Description

Detailed Description of the Invention 3. Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a pump device that uses circulating liquid to transfer solid matter, and particularly relates to a pump device that uses circulating liquid to transfer solid matter. The present invention relates to a solid-liquid transfer pump device equipped with a device for separating solids and liquids.

[Prior Art] When a pump that transfers a liquid contains air bubbles in the liquid, the transfer efficiency decreases, and in particular, a phenomenon occurs in which a rotary centrifugal pump becomes unable to transfer the liquid. The inability to transfer solids not only reduces transfer efficiency but also causes significant damage to the solids being transferred.

As shown in FIGS. 12 and 13, the present inventor installed a baffle plate 2 upright in a steam-water separation tank 1 with a predetermined volume and an open upper part to create a horizontally elongated liquid flow path. 3, air bubbles are floated and separated while flowing through the liquid flow path 3, and the liquid from which the air bubbles have been removed is used to transport the fish body along with the liquid to a high place or to a high speed passage using a pump. 26020).

However, since the transfer pump device having this structure is configured to separate air bubbles using the elongated liquid passage 3 of the air/water separation tank, the air/water separation tank 1 is quite long to separate the air bubbles. This has the disadvantage that the air/water separation tank 1 becomes considerably large in size because it requires a N.

That is, in the solid liquid transfer pump device shown in FIG. 12, since wastewater is supplied to the upper part of the steam/water separation tank 1, the wastewater supplied to the steam/water separation tank 1 flows forcefully and due to its inertial force. The bubbles are drawn into the liquid, and the problem is that the bubbles that are generated are extremely fine, and the bubbles sink to the bottom of the water separation tank along with the liquid, and the floating speed of the bubbles is surprisingly slow. While the liquid flows through the long and narrow passage,
The drawback was that it was extremely difficult to efficiently float and eliminate the bubbles. If the flow path is made narrower in order to make the liquid path longer, the flow rate becomes faster and sufficient bubble separation cannot be achieved.

[Objective of the present invention] The present invention was developed with the aim of further eliminating this drawback, and the present invention has been developed to efficiently remove air bubbles using a small-sized air-water separation tank, and to improve the efficiency of solid material transfer. It is an object of the present invention to provide a solid-liquid transfer pump device that enables solid-liquid transfer and damage-free transfer.

Another important object of the present invention is that when the liquid separated by the separator is quickly transferred to a mixing tank installed at a high place by a return water pump, an air/water separation tank can be connected to the suction side of the pump. The object of the present invention is to provide a solid-liquid transfer pump device that enables efficient operation of a return water pump and achieves highly efficient and damage-free transfer of solids.

[Means for Solving the Object] A solids-liquid transfer pump device includes a mixing tank that stores a solids-containing liquid, and a separator that is communicated with the mixing tank via a transfer pipe and separates the solids from the liquid. The separator separates the solids and liquid transferred through the transfer pipe, returns the separated liquid to the mixing tank, circulates the liquid, and transfers the solids together with the liquid.

In order to separate air bubbles contained in the liquid, a steam capacity tank is provided in the return water line leading from the separator including the mixing tank to the mixing tank. The upper surface of the steam/water separation tank is open to the atmosphere, and a water supply member that communicates with the separator is connected to the water supply member. A horizontal outlet for discharging in the horizontal direction is opened.

The liquid that is sent after the solids are separated by the separator is
Water is supplied by being sprayed in the horizontal direction near the water surface of the steam/water separation tank through the horizontal outlet of the water supply member.

[Operations and Effects] The liquid separated from the solid matter by the co-separator flows downward through the perforated plate of the separator in the form of countless shower-like water droplets, flowing down at high speed, but at the same time, it entrains the surrounding air. Bubbles are generated in the liquid. This liquid containing air bubbles is supplied to the original mixing tank via the return water line, and at least one air-water separation tank is installed in the return water line that includes the mixing tank.
The horizontal outlet of the water supply member injects the return water from the separator in the horizontal direction near the liquid level of the steam/water separation tank, thereby suppressing the separation of air bubbles and the generation of new air bubbles.

If water is supplied vigorously from the top to the bottom of the water separation tank as in the past, not only will the air bubbles contained in the liquid be removed, but when it falls to the water surface, the air at the water surface will be absorbed into the liquid. Involved, new air: a is generated, and both the new and old air bubbles are
Submerged deeply underwater and unable to surface easily, with considerable air and water λ
“Separation of air bubbles is not possible without the use of a tank.

In the charging system of the present invention, the flow direction of the return water from the separator is changed to the horizontal direction by the horizontal outlet of the water supply member that supplies liquid to the steam/water separation tank, and the water surface of the steam/water separation tank is By spraying from the vicinity in a horizontal direction, that is, parallel to the water surface, the generation of air bubbles is suppressed and air and water are allowed to pass through. Liquid that is supplied horizontally near the water surface of the air-water separation tank will not flow deep into the air-water separation tank because it will involve the surrounding air; Even if it contains air bubbles, the air bubbles are quickly separated due to the extremely short distance of 7♀.

The present invention does not separate air bubbles by flowing the liquid through a long channel as in the past, but instead supplies the liquid in a perfect condition to an air-water separation tank installed in the return water line. This reduces air bubbles contained in the liquid. Therefore, air bubbles can be efficiently separated using a small-sized air/water separation tank, eliminating the drawbacks of liquid transfer containing air bubbles, and realizing efficient transfer of solids (i.e., no-damage transfer).

In a preferred embodiment of the present invention, one or both of a solids transfer pump and a return water pump are connected between the mixing tank and the separator. The solids transfer pump transfers the liquid mixed with solids from the mixing tank to the separator, and the return water pump transfers the liquid 1 separated by the separator.
Reflux the book into the mixing tank. It is important that the ζ night body, which has a small amount of mixture of Qi and Bao, can be transferred well by the carving transfer pump; it is also important that the water return pump is able to efficiently return the liquid. In the present invention, the return water pump is separated by a separator? When transferring α(ho) to a mixing tank installed at a high place, by connecting a steam/water tank to the suction side of the return water pump, efficient operation of the return water pump is possible. It has the advantage of being able to achieve high efficiency and lossless transfer of solid materials.

It is fixed directly to the cylinder 12 so that it collides with the cylinder 12 and changes direction horizontally or horizontally in all directions.

The size of the turning plate 14 is determined to be larger than the cylindrical opening area, for example, 1.2 times or more, preferably twice or more, of the cylindrical inner diameter so that the liquid collides with the turning plate and changes direction.

Further, the gap between the turning plate 14 and the cylinder 12 is determined to have a cross-sectional area approximately equal to the cross-sectional area of the cylinder 12.

By the way, as shown in FIG. 1, the turning plate 14 is arranged completely horizontally with respect to the water surface. I! In other words, the horizontal outlet 15 of the water supply member should open completely horizontally to the water surface.

Even if $ is supplied to the water surface of the mixing tank, the bubble separation effect does not deteriorate at all.7 Therefore, in unknown gB, 15 horizontal delivery ports) Sending out liquid horizontally does not mean that it is completely horizontal. This includes a state where the device is tilted within 45 degrees with respect to the horizontal plane.

The solid liquid transfer pump shown in Figure 1 @Taka: Well, the liquid is refluxed horizontally near the water surface of the mixing tank 4, where crushed ice is floating on the surface and fish are settling on the bottom.

When the fish in the mixing tank 4 are gradually sent out and there are few remaining, if the drain valve 17 is opened to drain the liquid separated by the separator 7, the amount of liquid in the mixing tank 4 is reduced, and the fish can be collected and transferred efficiently. .

As shown in FIGS. 1 and 3, the mixing tank 4

It consists of a water return pump 18 and a water return pipe 8 provided in the water return line, and a water supply member 9 arranged near the water surface of the steam/water difficulty tank 19.

In this device, water naturally flows down into the mixing tank due to the water level difference H between the separator 7 and the mixing tank 4, and the solid fish is transferred to the separator 7 along with the liquid. The liquid separated by the separator 7 is returned from the air/water separation tank 19 to the mixing tank 4 through the return pipe 8 and the return water pump 18, and the mixing tank 4 is constantly maintained at a water surface level H higher than the separator 7. be done. The operation of the return water pump 18 is controlled by the level sensor 20 of the mixing tank 4, and it is operated when the water level of the mixing tank 4 decreases, and is stopped when the water level rises above a certain level, and the operation of the water return pump 18 is controlled by the level sensor 20 of the mixing tank 4. The water level difference H with the steam/water difficulty tank 19 is maintained within a certain range.

The fish is separated from the liquid with a separator and removed.

The horizontal outlet 15 is located in the gap between the drainage "rR21" and the turning plate 14.
is formed, and the liquid separated by the separator 7 is distributed horizontally from the horizontal outlet and supplied to the steam/water separation tank.

When the water surface level of the steam/water separation tank changes, the relative position between the water surface and the turning plate 14 changes.

When multiple fish are supplied to the mixing tank 4, the water level in the air-water separation tank 19 rises, and the turning plate 14 sinks below the water surface. The falling liquid is redirected horizontally so that air bubbles 71) are separated without going deep into the liquid. Turning plate 14
If it is floated on the water surface of the steam/water separation tank 19, the turning plate 14 will always be located on the water surface even if the water surface of the steam/water separation tank 19 fluctuates somewhat.

The solid liquid transfer pump device shown in FIG. 5 is for transferring solid substances such as oranges floating on water, and includes a mixing tank 4, a solid transfer pump 6, a separator 7, a steam/water separation tank 19a,... 19b, and a water supply member 9.

The water supply member 9 of the steam/water separation dunk 19b communicates with the water return pipe 8 which passes through the water/water difficulty tank 191 vertically upward and opens near the water surface, and the It is composed of a turning plate 14 arranged horizontally and separated by a predetermined distance. The upper end of the opening of the water return pipe 8 and the turning plate 1
4 and a horizontal outlet 15 are provided.

On the other hand, a Lenopel sensor 25 is installed at the top of the mixing tank 4.
is provided and configured to detect the level of orange in the mixing tank 4 and start/stop the supply container 26.

A separator 7 is provided at the discharge control point of the solids transfer pump 6, and a steam/water separation tank 19a is also provided below the separator tough. This steam/water difficulty tank 19a is provided with a turning plate 14 above the water surface near the water surface, and the turning plate 14 forms a horizontal outlet 5.

The method of operating this device is to first supply water to the steam/water separation tank 19a from an external water source such as tap water (not shown), and wait until the water reaches a predetermined level in the steam/water separation tanks 19a, 19b and the mixing tank 4. , the solids transfer pump 6 is started and operated. Water flows through the steam/water separation tank 19b, the mixing tank 4, the solids transfer pump 6, the separator 7, and the steam/water difficulty tank 19a, and the water returns from the steam/water difficulty tank 19a to the water return pipe 8.
The water is returned to the steam/water separation tank 19b and circulated through the tank 19b. When the solids transfer pump 6 is in a normal operating state,
Preparation is complete when the flow reaches a quantitative state.

Next, the supply container 26 is operated to supply oranges into the mixing tank 4, and when the lower limit of the level sensor 25 is reached, the solids transfer pump 6 is started and operated.

In this case, as shown in the figure, some of the oranges are exposed to the atmosphere at the top of the water surface L2 of the mixing tank 4 and are exposed to the atmosphere, and some of the oranges are pushed down below the water surface due to the weight of the oranges at the top. It is immersed in water.

What is sucked into the solids transfer pump are the oranges pushed down below the water surface, which are sucked together with the water in the mixing tank toward the solids transfer pump, and are forced into the separator via the transfer pipe.

Therefore, oranges are supplied one after another from the supply conveyor 26, and a certain amount of oranges are deposited in the mixing tank 4, and the oranges supplied first one after another are due to the weight of the oranges supplied later. Then, the solids are pushed down into the mixing tank 4 and settled, and are sucked and pumped together with running water by the solids transfer pump 6.

As the water and oranges in the mixing tank 4 are sucked into the solids transfer pump 6, the water surface level L2 in the mixing tank 4 drops instantaneously. Water flows into the mixing tank 4, and the inside of the mixing tank 4 is always at a predetermined water level L2.

The action of the turning plate 14 provided below the separator 7: The turning plate 14 turns the high-speed water in the horizontal direction and forms a thin, slope-like water film that is dispersed in all directions and falls onto the water surface. . The fractional direction of the water film is very horizontal, and even if it falls to the water surface L3 of the air/water separation tank 19a, it will not sink deeply into the water. The position of the turning plate 14 may be near the water surface, fl slightly submerged in the water, or may be above the water surface near the water surface as shown in FIG.

Even if the returned water from the air-water separation tank 19a is controlled by the turning plate 14 so as not to contain air bubbles, it may still contain some air bubbles if the air-water separation tank 19a is small. be. In addition, when water is returned to the air-water separation tank 19a, air bubbles may be mixed in again if the water is supplied at high speed. It is also provided in the air/water external tank 19b.

In FIG. 5, the water return pipe 8 extends from the bottom to the top of the steam/water difficulty tank 19b. The turning plate 14, which is disposed horizontally near the water surface L1, is blocked by the turning plate 1↓ from the water blown out from the water return pipe 8, and is dispersed in a film shape in the horizontal direction, causing air bubbles to mix into the water. prevent. For this reason, the air/water separation tank ζ:! Can you return the water from the return pipe 8 at high speed? In this case, the turning plate 14
Nearby, it can be on the water surface or underwater, or if the water from the return pipe 8 contains almost no bubbles, it can be underwater.
Fl rarely occurs.

In the steam/water separation tank 19 shown in FIG. 6, the turning plate 14 is fixed and protrudes to the outside, and the outer periphery of the turning F&14 is surrounded by a partition-like turning part 27.

The turning plate 14 is arranged horizontally near the water surface of the steam/water separation tank 19. The pipe 1 is placed vertically above the turning 1 14, and the water return pipe 8 is arranged vertically. Lower end of water return pipe 8 and turning plate 1
A horizontal outlet 15 is formed on the upper surface of the turning plate 14 using the water supply glIJ material 9 consisting of 4.

Further, the steam/water separation tank 19 shown in FIG. 7 is provided with a turning plate 14 extending horizontally and outwardly a little above the water surface. That is, the water supply member 9 with this structure
is formed into a box shape with a horizontal outlet 15 opening in the steam/water separation tank 19 by the turning plate 14, the turning member 27 on the outer periphery, and the bottom plate 28, and the bottom plate 28 is vertically penetrated from bottom to top; A water return pipe 8 is connected thereto.

Furthermore, the turning plate 14 shown in FIG.
A water return pipe 8 is vertically disposed above the turning plate 14 by a float floating on the turning plate 9, and the direction of water supplied from the water return pipe 8 is horizontally changed by the turning plate 14.

Further, as the turning plate 14, as shown in FIG. 9, a perforated plate disposed near the water surface can also be used. Turning plate 1 which is a perforated plate
4, some of the water penetrates and flows downward, but the inertial force of the water is decelerated at the time of penetration, and bubbles do not sneak to the bottom of the steam/water separation tank 19. A part of the water that collided with the upper surface ξ of the deflection +Fi, 14 is supplied horizontally through the horizontal outlet 15 formed by the deflection plate 14 and the lower end of the water return pipe 8, thereby preventing the generation of bubbles.

Furthermore, the steam/water tank 19 shown in FIG. A buffer chamber 29 is formed in 19. The turning member 27 forming the buffer chamber 29 is a partition whose upper edge extends near the water surface, and forms a horizontal outlet 15 above the turning member 27. The water supply member 9 does not need to specify the direction in which the water return pipe 8 supplies liquid to the buffer chamber 29. Therefore, the water return pipe 8 can be arranged vertically as shown in FIG.
Alternatively, although not shown, it is also possible to connect the water return pipe directly through the wall of the buffer chamber.

Air and water external tank 19 shown in the vertical sectional view of FIG. 11;
Three-dimensional ζ is arranged in a narrow space to promote the effect of separating air bubbles into a raised system.

In FIG. 11, the steam/water separation tank 9 is separated into two upper and lower chambers 31 and 32 by a partition plate 30.

The lower chamber 32 is communicated with the upper chamber 31 by a communication pipe 33, and the lower chamber 32 is connected to the upper chamber 31. Return pipe 8 or upper chamber: 31 has drain pipe 3
4 are connected, external, and open, respectively, as shown in the figure.

The float valve 31 is configured to open when the float 36 descends.

A turning plate 14 is disposed near the water surface of the upper chamber 31 at the upper open end of the communication pipe 33, and a water return pipe 8 is disposed near the water surface of the lower chamber 32.
A turning plate 14 is disposed on the opening end surface of the opening.

The function of this water supply tank will be explained below by supplying water containing air bubbles from the separator through the return pipe 8.
The turning plate 14 installed near the water surface of the lower chamber 32 allows the water to be moved near the water surface (to disperse the energy toward the water surface, and to disperse the air contained in the water over a wide plane, allowing the water to dive deep underwater). Without doing so, the bubbles immediately rise and disappear on the water surface L4.

In this case, to explain the action of the float valve 35, the float 36 is descending until it reaches the predetermined water surface L11 after water is supplied to the royal house 32, so the float valve 35
2 is fully 1fi, and the air in the lower chamber 32 is freely exhausted to the outside. As the water level gradually rises, the float valve 35 acts in the closing direction until the water level reaches L4 and n is fully closed. In this state, a sealed air chamber is formed above the water surface L4 of the lower chamber 32. By supplying water after the float valve 35 is fully opened, air bubbles contained in the supplied water are floated and separated as described above, and the air pressure in the air chamber increases. Water is pushed upward from the communication pipe 33 by the action of the air pressure and is supplied to the upper chamber 1. Then, the water volume in the upper chamber 31 gradually increases by 1, and finally the water surface L
Reach 5. Due to the air bubbles contained in the water return pipe 8, the separated air accumulates in the air chamber, and as the air pressure increases, the water surface L4 falls. When the water surface L4 falls, the float valve 35 opens, and the air in the air chamber is discharged to the drain, and the water surface L4 always maintains a predetermined position.

Since the turning plate 14 is also provided at the upper end of the communication pipe 33 as shown in the figure, air bubbles are separated by the same effect as described above. The water surface L5 of the upper chamber 31 is always operated at a predetermined position,
Since a large amount of liquid may be supplied from the separator at one time and the water level L5 temporarily rises, in that case, the water is drained from the overflow port 37. Also, air-water separation tank 1
If the water supply to No. 9 temporarily decreases, replenish fresh water from the float valve provided at the left aperture of the upper chamber from 3 days onwards.

The float valve 38 communicates with a water source 39, and is configured to open to supply water when the water level decreases below a predetermined level, and close when the water level L5 rises. The float valve 38 may be used to supply water when initially supplying water to the steam/water separation tank 19 in preparation for operation.

In the air-water separation tank 19 shown in FIG. 11, air bubbles are separated from the water discharged from the bottom of the upper chamber 31 by the air bubble separation action of the water return pipe 8 and the turning plate 14 in the lower chamber 32 and the communication pipe 33 and the turning plate 14. Mixing tank 4 becomes water only.
supplied to Furthermore, although the steam/water difficulty tank 19 is separated into two upper and lower chambers and its installation area is reduced, it has the function of efficiently separating air bubbles.

Furthermore, although the partition plate 30 that separates the upper and lower chambers into two chambers has a large area, during operation, the water pressure in the upper chamber 31 and the lower chamber 3 are separated.
Since the air pressure in the second air chamber is balanced with the air pressure in the second air chamber, there is no need to create a pressure structure because they are balanced with each other. That is, the partition plate 30 does not require reinforcement to prevent deflection.
