Description

The The invention relates to a method for cleaning the interior of a empty storage tanks and / or for stirring one inside a storage tank located stock liquid, wherein Outlets within the storage tank for stirring with the stock liquid or for cleaning with a Cleaning / rinsing liquid are pressurized and the stock liquid or the cleaning liquid deploy within the storage tank and a stirring and Cleaning device.

in the State of the art are different stirring and cleaning devices for storage tanks, for example from the field of sprayers and industrial liquid distribution machines.

From the DE 39 21 092 A1 For example, a stirring device for stirring a liquid in a liquid tank of an agricultural field sprayer is known. In this case, a stirring line is led from the upper region of the storage tank to approximately the bottom, where this stirring line divides into two opposite outlet openings, through which the corresponding liquid can be pumped within the storage tank. This results in a circulation of the liquid within the storage tank.

The DE 200 18 717 U1 discloses, by way of example, a stirring arrangement, namely a hydraulic stirrer, for mixing pesticides with water, in which a stirring line with stirring nozzles is arranged in a liquid tank. The mixing takes place here by pumping the liquid from the liquid tank and reintroducing the liquid through a stirring. The agitating nozzles distribute the pumped liquid such that a directional flow is created within the liquid tank. This should be done a uniform mixing.

Of Further, in the general state of the art storage tanks of Sprayers, deicers, storage containers and The like are known in which individual nozzles in the wall of the storage tank are arranged so that liquid out is pumped out of the tank at one point and by a variety introduced from nozzles in the wall in the tank becomes. Again, the goal is to mix the liquid well.

Problematic at the previously known in the art stirring and Cleaning devices for liquid containers and the corresponding method is the poor mixing of the contained liquid. It is desirable that a level-independent constant concentration the components of the fluid within the whole Storage tanks remains guaranteed. Next is the stirring preferably without the introduction of air into the liquid so as not to cause foaming or blistering comes.

simultaneously it is problematic in the known stirring and cleaning devices, that a variety of supply lines, valves, pumps and the like is necessary to get the required uniform Concentrate within the liquid of the storage tank to ensure.

task The invention is a stirring and cleaning device and to specify a method with which it is possible a uniform concentration within one To comply with liquid in a storage tank, in particular To prevent sinking suspended matter within the liquid gather at the bottom of the storage tank.

Farther It is an object of the invention, a stirring and cleaning device and to provide a method with which effective cleaning Storage tanks, in particular adhering deposits and Residues is effectively possible.

Solved This object is achieved by a method according to claim 1 and a Apparatus according to claim 13.

If a rotatably mounted between two receptacles tube on the Lateral surface arranged the outlet openings are to turn a rotation axis between shots is it possible to have a homogeneous, even and equally distributed concentration of the fluid within to realize a storage tank. This can improve the quality of the stored liquid over a longer period of time be granted. Furthermore, a separation of the liquid actively prevented in their individual components, so it does not flocculation or the like comes.

Of Furthermore, it is possible to make the storage tank more efficient clean and remove any residue.

Thereby, that turning depending on the level height takes place, stirring and / or cleaning may be required be performed. Here, in particular, the stirring and / or cleaning is activated and deactivated. Next, for example the rotational speed or the pressurization according to the Be adapted to needs.

Since withdrawing takes place regularly from the storage tanks and thus the level always changes, the pressurization takes place depending on the filling level. The Druckbeauf At a high filling level, high pressures can be used to circulate a larger quantity of liquid. For smaller filling levels, the pressurization can be carried out with smaller pressures, so that the effective range of the liquid emerging from the outlet openings is lower than during high pressurisation.

Thereby, that the shots during the stirring or the Cleaning in height can be changed during the stirring or during cleaning the Altitude of the pipe can be varied to all Areas of the storage tank with the out of the outlet openings to reach the exiting liquid.

Around foaming, air spraying or the like To prevent, the stirring of the stock liquid takes place at a level height in the range of maximum Filling level up to an upper filling level, in the case of an overlap of the effective range of the outlet openings with the stock liquid is just given, by circulating Turning the pipe while pressurizing.

If a portion of the liquid is removed, the liquid level decreases inside the storage tank, which increases the filling level reduced. Stirring the stock liquid takes place at a level height in the range of the upper level to a lower level Level height at which an overlap the effective range of the outlet openings still exists, by rotating the tube in a swivel range <360 ° with simultaneous pressurization, the bisector of the swivel range from the vertex Oriented downwards, since this is the effective range of the outlet openings leaking fluid within the storage liquid of the storage tank is held. An impact on the level height will be prevented.

If The swivel range in the upper level range up to the lower filling level depending on from the level height continuously or stepwise is reduced, wherein the bisector of the pivoting range from the vertex is still directed downwards, is permanent ensures that no impact from the outlets leaking fluid over the level the stock liquid takes place.

Around foaming or the like of the stock liquid in a lower area, will prevent stirring the stock liquid at a level height stopped below the lower filling level. In particular, would in a rigid arrangement of the tube within the storage tank, an area below the pipe exist, in which the liquid emerging from the outlet openings directly would be discharged to the air. Thus, would the exiting liquid air particles in the remaining storage liquid contribute to a negative quality impact the stock liquid and to the already mentioned above Foaming would result.

Farther it is conceivable that the stock liquid within the Storage tanks behaves such that one above the Liquid floating layer, for example, a forming skin, which is present by distributing the outlets leaking liquid above this layer to a Mix this layer with the stock liquid would. For example, this could lead to contamination at the sampling point or other lines within a sampling device to lead.

Thereby, that cleaning only with a remainder of stock liquid or empty storage tank, wherein the cleaning by circulating Turning the pipe or turning the pipe in a swivel range with simultaneous pressurization with the cleaning / rinsing liquid or water takes place, the bisector of the swivel range From the vertex is oriented upwards, first the still existing stock liquid neither diluted still contaminated. Furthermore, the cleaning / rinsing liquid or the water also not strong by the remaining liquid contaminated. Both lead to a reduction of disposal costs. By a rotating rotation of the tube all Areas of the interior of the storage tank with the cleaning / rinsing liquid or the water sprayed out of the orifices is applied. Alternatively, it may be enough just one turn to perform the hollow shaft in a swivel range, as residual fluids Gravity caused within the storage tank on the walls after would run downstairs. In the lower area of the storage tank can these cleaning / rinsing liquids or the water, which is contaminated accordingly, aspirated and then disposed of.

In order to counteract a constant switching back and forth of the process status during a movement of the storage tank, for example in an arrangement of the storage tank on a vehicle, which moves through uneven terrain, and leads to a back and forth sloshing of the storage liquid to counteract, the switching is done by stirring with rotating rotation, stirring with rotation in a swivel range, stopping the pressurization and rotation and cleaning automatically, wherein after switching from one area to another area within a tolerance range of the level height is not switched back to the previous process status.

Of the Pressure will vary depending on the process status and cleaning controlled. In this case, preference is given to stirring driven with a lower spray pressure than when cleaning. When cleaning, the higher pressure is used to spray the interior of the storage tank. As a result, the surface is sufficient freed from the stock liquid and cleaned from residues.

Especially It is advantageous if the stirring, the removal of a Part of the stock liquid, the pressurization and Introduction into the tube, the application of the pressurized stock liquid through the outlet openings in the storage tank in one operated closed circuit. For this purpose, the stock liquid at any point, but preferably at the lowest point of Storage tanks are pumped and by a corresponding pumping arrangement again with the help of the tube and the corresponding outlet openings be introduced into the storage tank.

According to the rules o. g. Problem solved by the fact that the outlet openings are arranged on the lateral surface of the pipe and the pipe is rotatably mounted in recordings about a rotation axis.

Thereby, that the effective range of the outlet openings predominantly is aligned in the radial direction, wherein the outlet openings are oriented near walls of the storage tank such that whose effective range points in the direction of the wall of the storage tank, is over the entire space area or interior of the storage tank sufficient stirring of the stock liquid guaranteed. In particular, the edge regions of the interior again and again problem areas, which now sufficiently stirred so that no separation or deposits form here can. The same applies to cleaning, so that also problem areas from the leftovers of the stock liquid and Residues and deposits freed or cleaned become.

If the outlet openings as nozzles, preferably as Injector nozzles or ball head nozzles formed are, wherein the ball-headed nozzles preferably eccentrically rotating are formed, the effective range of each individual nozzle further increased, since both the effective range extended as well as rotationally symmetrical enlarged.

The Pipe can be turned manually operated. For further improvement and Automation is a rotary drive for turning the tube intended. In particular, the rotary drive means is a water motor, an electric motor, a pneumatic drive, a lever or coupling gear and / or a hydraulic motor, wherein rotational speed and direction of rotation are customizable.

If a sealing passage for the pipe through the wall of the storage tank is provided, the pipe can through the wall of the storage tank are guided directly. hereby can be a complex construction and protection arrangement of the required Objects, such as the pressurizing agent or the like, are dispensed within the tank, so that these devices in the simplest way outside of the storage tank can be arranged and at the same time the pipe is supplied with the appropriate liquid can.

Farther it is particularly advantageous if the pressurizing agent and / or the rotary drive means outside the storage container are arranged. Any required maintenance These devices can be especially simply done.

Especially the pressurizing agent is a pump. The pump is here particularly preferably designed as a pressing pump.

Around a homogeneous stirring within very large To ensure storage tanks, several pipes are in the Storage tank rotatably arranged. Both over the length, the width, as well as the height is the arrangement several pipes in the storage tank useful, preferably all Pipes with a pressurizing agent with the liquid be supplied. In this context, would fall below the lower filling level of the respective pipe the corresponding pipe via controllable valves not be pressurized more. Turning for this tube is finished at the same moment.

Especially Preferably, the axis of rotation (s) are / are aligned horizontally. in this connection can the outlet openings of the corresponding Pipe are liquid supplied with the same pressure. alternative If the axis of rotation (s) is / are aligned vertically. Here you have to the outlet openings of each tube can be controlled individually be. This can, for example, via electrically controllable Valves can be reached via a bus system, so that the Valves at a decreasing level within the storage tank be switched off from top to bottom in turn.

Because the recordings are fixed on the or in the storage tank, a low-maintenance static arrangement is realized to perform the stirring and cleaning.

alternative are the shots along the wall sides of the storage tank, at which they are arranged movable and adjustable, wherein preferably an adjustment by means of a drive is provided. To move the recordings by means of the drive can For example, electric motors, pulleys, linkage arrangements or the like, the corresponding rotational movements translate into linear movements. Alternatively, you can do this but also linear actuators or hydraulic rams are used. Furthermore, an arrangement on a rotation disk is possible, allowing a spatial movement of the tube in two dimensions done in the room.

Around the efficiency especially in lower areas of a storage tank to further optimize, the tube has one at each end Cranking on, wherein the crimp angle respectively in the Range of 5 to 110 °, preferably in the range of 70 to 108 °. This will result in a very large stroke range and the associated effective range, which at the same time by a variable restricted pivoting range is limited, designed, so that in particular at very low level heights still be successfully carried out a stirring can. Here, in particular, the region of the tube of outlet openings keep clear who is near the recordings. This area is in particular starting from the respective admission to the end of the See offset, otherwise the outlet openings In this area may not be sufficient with the stock liquid are covered within the storage tank, whereas the largest number the outlet openings still far below the level height the stock liquid is located within the storage tank.

Thereby, that the effective range of the outlet openings in the way from the respective recording expiring Kröpfbereichen of the pipe and the

arrangement is oriented on the lateral surface of the tube such that the effective area towards the nearest wall of the storage tank, the walls of the storage tank, at the the recordings are sufficiently cleaned or the stock liquid sufficiently mixed / stirred in these edge areas.

to Realization of a cyclic flow within the storage tank the outlet openings are spiraling on the Lateral surface of the tube is arranged. Here you can several revolutions of the tube are provided. In particular, you can but also, as already mentioned above, individual nozzles be switched on and off. For this purpose, a BUS system is particularly preferred to use, for example, solenoid valves on the individual nozzles controls.

to uniform mixing of the stock liquid inside the storage tank are the outlet openings equidistant, preferably at a distance of 20 to 50 cm and particularly preferably at a distance of 25 cm from each other, on the Lateral surface of the tube is arranged.

Around the largest possible number of storage liquids or to be able to use liquids for cleaning, If the tube is made of metal, preferably stainless steel and is preferred a round tube. Alternatively to the design of the tube made of metal can also be plastics, which are preferably fiber-reinforced, be used. Here, in particular, the resistance to to observe the storage liquids to be stirred.

Further is an additional tank with a cleaning / rinsing fluid or filled with water / filled, wherein an additional supply line for supplying the cleaning / rinsing liquid or the water is provided to the pressurizing means, making short-term switching between stirring with the stock liquid and cleaning with a cleaning / rinsing liquid or with water is possible. Alternatively leaves About this additional tank, a concentrate, such as a pesticide or the like, stockpiled as needed is introduced into the storage tank. It would be special here makes sense if initially only water would be present in the storage tank. By introducing the concentrate just before using the Stock liquid, for example, a ready mixed Plant protection product, a deicing agent or a cleaning agent can For example, high transport costs are avoided, which arise would, if very large quantities of ready mixed Supply liquid from one filling point to a place of application or place of use would have to be brought. In In this context, it is desirable that water Place first in the storage tank, then add the concentrate and finally carry out a stirring.

to full automation are level sensors for determining the filling level in the storage tank arranged.

1 shows the stirring and cleaning device 1 in a storage tank 2 , The storage tank 2 gets out of the wall 21 formed and encloses the interior 22 , In the storage tank 2 there is a storage liquid 3 , In the lower area of the storage tank 2 is a removal 25 provided, which serves the stock liquid 3 from the storage tank 2 refer to.

Inside the storage tank 2 there are two shots 24 for receiving a pipe 11 , The pipe 11 is in the shots 24 rotatably mounted, with the tube 11 rotates about a rotation axis x.

The pipe 11 points to its lateral surface 12 outlet openings 13 on. These outlet openings 13 are in this embodiment as nozzles 13 educated.

The outlet openings or the nozzles 13 have an effective range 15 , This effective range 15 is the area where the leaking fluid from the outlet openings, nozzles 13 inside the interior 22 or within the stock liquid 3 can work. This effective range 15 does not, however, include all the flows caused by the stirring movement or the outflowing liquid from the outlet openings, nozzles 13 within the stock liquid 3 arises. Rather, caused by the exiting liquid from the outlet openings, nozzles 13 complex flow processes, turbulences and mixing, which are not shown here.

Through the pipe 11 a liquid is transported under pressure, as already described above, from the outlet openings, nozzles 13 in the storage tank 2 is introduced. To get this liquid first into the tube 11 to bring in is the pipe 11 about an implementation 23 in the wall 21 of the storage tank 2 led to the outside, where a line 32 to the pipe 11 connected. This line 32 is on a pump 31 connected, which forms the pressurizing means in this case. The pump 31 is in this embodiment with the storage tank 2 about the removal 25 connected, whereby it is possible, a part of the stock liquid 3 at the removal 25 from the storage tank 2 and in the sense of a circulation process via the pipe 11 in the storage tank 2 due.

As a result, a circulation process is realized in which the storage liquid 3 inside the storage tank 2 sufficiently stirred and kept homogeneous. To stir the stock liquid 3 becomes the stock liquid 3 self-used.

In this embodiment, the storage tank 2 about 80% with the stock liquid 3 filled. The fill level of the stock liquid 3 inside the storage tank 2 is readable on the basis of the filling height h. This fill level h can for example be optically detected or detected by level sensors and fed to a central control unit as a data signal. The level height h is used in particular to activate and deactivate the stirring movement as well as the pressurization of the tube 11 , The dependence of the pressurization and the rotation is particularly in the 3a . 3b . 3c for this embodiment, as well as in the 4a . 4b . 4c for a further embodiment according to 2 shown in more detail.

Furthermore, a valve arrangement 34 provided to the one more line 32 is arranged, at the other end a consumable element 33 having. This consumable item 33 in interaction with the management 32 and the valve assembly 34 serves to remove stock liquid 3 from the storage tank 2 , The removal is in particular by the pump 31 and a corresponding switching of the valve assembly 34 , as well as over the dimensioning of the lines 32 affected.

The administration 32 from the removal 25 via the pressurizing means, the pump 31 , up to the valve assembly has a large cross-section, which then divides into two new, smaller lines, each with a smaller cross-section. As a result, sufficient stock liquid 3 circulated and sufficient stock liquid 3 remains free for removal.

The overall arrangement of in 1 illustrated embodiment represents an agricultural field sprayer, wherein the consumption element 33 is an example of deployable spray arms of an agricultural sprayer with corresponding spray nozzles. The arrangement looks similar when used for a building sprayer such as a de-icing machine or the like.

For further operation of the stirring and cleaning device 1 according to 1 will be on the 3a . 3b and 3c directed.

2 shows a schematic representation of a second embodiment of the stirring and cleaning device.

Same Components are also provided below with the same reference numerals.

The storage tank 2 will, as already in 1 described, from the wall 21 formed and encloses the interior 22 , The stock liquid 3 is in the storage tank 2 , On the representation of the outside of the storage tank 2 located devices is omitted here, since these already the 1 are removable.

Inside the storage tank 2 again there are two shots 24 for receiving a pipe 11 , The pipe 11 is in the shots 24 in turn rotatably mounted about the axis of rotation x.

Different from 1 However, the design of the tube 11 , The pipe 11 has at its ends in each case a crank 14 . 14 ' on. The cranes 14 . 14 ' are bent in a Kröpfwinkel β. This forms a double-cranked tube 11 out.

The pipe 11 points to its lateral surface 12 the already mentioned outlet openings 13 on, for example, as nozzles 13 are formed.

The outlet openings or the nozzles 13 have an effective range 15 which in this embodiment is different than the effective range 15 out 1 is trained. The effective range 15 is in 2 smaller, because of the two cranks 14 . 14 ' the pipe 11 a larger spatial coverage area within the storage tank 2 by a rotation about the axis of rotation x.

The outlet openings, nozzles 13 of the pipe 11 are preferred in the crank area 14 . 14 ' and the areas in the recording 24 not provided.

For the operation of the stirring and cleaning device 1 according to 2 will be on the 4a . 4b and 4c directed.

In the following, the operation of the stirring and cleaning device 1 explained in more detail:
In the 3a . 3b and 3c is the first embodiment of the stirring and cleaning device 1 out 1 resumed, here the cross section through the in 1 shown stirring and cleaning device 1 is shown.

3a shows a schematic representation of the operation of the first embodiment of the stirring and cleaning device 1 while stirring.

Inside the storage tank 2 with its the interior 22 bounding wall 21 is the pipe 11 rotatably arranged. Exemplary is an outlet opening, nozzle 13 with an effective range 15 shown.

The storage tank 2 is with the stock liquid 3 filled to a great extent. The filling height h is shown on the side. Now, two more level heights, namely the upper level height oh and the lower level height uh are shown. The upper level height oh represents the level height at which the effective range 15 the outlet opening, nozzle 13 still completely with the stock liquid 3 is covered. The lower level height uh represents the fill level of the stock liquid 3 in which the stock liquid 3 still above the outlet opening, nozzle 13 is, so the effective range 15 the outlet opening, nozzle 13 at a lowermost point, namely in the vertically downward exit point of the outlet opening, nozzle 13 , completely in the stock liquid 3 is.

How out 1 known, the tube rotates 11 around the rotation axis x. In 3a this movement is a 360 ° continuous rotation, since the level height h is above the upper level height oh.

This rotation is performed in a swivel range α, in which case, as already mentioned above, a complete circumferential rotation of the tube 11 is performed in the swivel range α. Nevertheless, it can also change direction come so that after one or more successive revolutions, a change between clockwise rotation and counterclockwise rotation takes place, these changes can also be dependent on, for example, a predetermined time. For this purpose, of course, sensors may be present which detect the rotation and the number of rotations.

3b shows a schematic representation of the operation of the first embodiment of the stirring and cleaning device during stirring.

In 3b is now after the reduction of the level height h of the stock liquid 3 by removing further stock liquid 3 the swivel range α is reduced. The pivoting range α now extends to a limited portion of a circle in which the tube 11 is swung back and forth.

Around indicate the direction of the swivel range, the bisector α / 2 shown. The bisecting line α / 2 is directed downwards.

The swivel range α became due to the reduced liquid supply of the stock liquid 3 limited. Now the level is h below the upper level height oh and above the lower level height uh. Upon further reduction of the filling height h, there is an analogous reduction of the swiveling range α, so that it becomes smaller.

to Further elaboration will be made to the above textual description Adjustment of the swivel range α referenced.

3c shows a schematic representation of the operation of the first embodiment of the stirring and cleaning device when rinsing.

It is now the storage tank 2 without the stock liquid 3 shown. The stock liquid 3 is from the storage tank 2 completely removed. Now it requires a thorough cleaning of the emptied interior 22 and in particular the wall 21 ,

Cleaning the storage tank 2 takes place by means of a rinsing and cleaning liquid or with the help of water, which passes through the pipe 11 is passed at high pressure, then the outlet opening, nozzle 13 leaves and against the wall 21 of the interior 22 is injected. This dissolves any deposits and residues of the stock liquid 3 from the wall 21 and be transported by gravity and the enticing water or the enticing flushing and cleaning liquid down.

The cleaning or rinsing of the storage tank 2 takes place here in a swivel range α, which is oriented upwards. Based on the size of the effective range 15 it can be seen that the pressure of the rinsing and cleaning fluid is higher than in the process state stirring 3a and 3b , Now the effective range is sufficient 15 to the wall 21 of the storage tank 2 approach.

4a shows a schematic representation of the operation of the second embodiment of the stirring and cleaning device during stirring.

In analogy to the 3a . 3b . 3c , which have each related to the first embodiment, are the 4a . 4b . 4c now directed to the second embodiment. They represent a cross section through the center of the storage tank 2 represents.

This is a double-bent tube 11 which is moved within the storage tank.

Through the two cranks 14 . 14 ' is the largest part of the pipe 11 outsourced from the axis of rotation x, so that now a very large turning radius for the majority of the tube 11 results. In particular, characterized in that the outlet opening, nozzle 13 preferably in the area between the two cranks 14 . 14 ' on the lateral surface 12 of the pipe 11 are arranged, are no outlet openings, nozzles 13 in the area between cranking 14 . 14 ' and recordings 24 intended.

When turning the pipe 11 A larger area, a larger volume can now be passed through about the axis of rotation x. In this case, lower pressures are sufficient to ensure uniformly homogeneous mixing of the stock liquid 3 to obtain.

In 4a is still a rotating rotation due to the high level height h possible. With continuous removal of the stock liquid, however, this rotating rotation of the tube 11 stopped in the swivel range α, as an upper level height oh is exceeded.

In embodiment of the tube 11 such that the outlet openings, nozzles 13 on the axis of rotation x directed part of the lateral surface 12 of the pipe 11 can be arranged, the duration of the rotating rotation of the tube 11 with constant / uniform removal of the stock liquid 3 be maximized, since thereby the effective range 15 contrary to the version shown here in the interior 22 , is always directed in the direction of the axis of rotation x.

4b shows a schematic representation of the operation of the second embodiment of the stirring and cleaning device during stirring.

In 4b is by removal of the stock liquid 3 the level height h is reduced. Now, the upper level height oh falls below what the tube 11 only in a reduced pivoting range α is pivoted back and forth.

4c shows a schematic representation of the operation of the second embodiment of the stirring and cleaning device when rinsing.

The empty storage tank 2 is done with the help of the revolving tube 11 cleaned. Instead of a complete rotating rotation of the tube 11 is also the pivoting in an upward pivoting range α possible. For this, refer to the analogue version in 3c directed.
