The invention relates to the field of product cleaning, and the cleaning technology to the equipment is a variety of parts and assemblies, and can be used in repair plants and in various areas of npoNibmmeHHOcTH. The purpose of the invention is to improve the quality of cleaning. Fig. 1 shows schematically an installation for washing products (longitudinal section), a general view; in fig. 2 - e, top view; in fig. 3 is a section A-A in FIG. 2; in fig. 4 is a section B-B in FIG. I. The apparatus for washing products has a bath 1 for washing liquid, a drive 2 for vertical reciprocating movement and rotation of the holder 3 with products, With a guide 2 for vertical return-accessible movement and rotation associated frame 4 to accommodate the holder 3 and the shell 5 with nozzle sleeves 6 and spring-loaded check valves 7. Both the gull 5 is installed under the frame 4 which is perforated and has profiled blades 8 The unit is equipped with a sleeve 9, a leash 10, a supporting piston 11, An on 1 is provided with a lid 12 with clamps -13 and a drive 14 Kryshki 12, A drive 2 of vertical reciprocating movement and rotation contains engines 15, gears 16, spindle screws 17, The unit is equipped with lugs 18, seal 19, rod 20 with a screw groove 21, a turbo collector propellant 22 with a crane 23 and a collector 24. The installation has a drainage pipe 25 and a crane 26, a pipeline 27, valves 28 and 29, a delivery pipe 30 and 31, a cleaning liquid 32, a cleaning liquid 33 , boot pipes 34 and 35, valve 36 and 37. The holder 3 has, for example, a lattice design with a small intrinsic hydraulic resistance. Bath 1 is structurally made of sheet, for example, stainless steel with thermal insulation and is able to withstand excess pressure. From above, the bath 1 is closed by a lid 12, structurally designed from the sheet steel with thermal insulation, which surpasses the excess 3 pressure. The cover 12 may have a rubber seal, a safety valve protecting the bath 1 from excess pressure. Inside the bath 1 there is a perforated frame 4 with profiled blades 8, a sleeve 9, a leash 1 O, and a support bearing 1I. The perforated frame 4 is a metal structure with low flow resistance. The sleeve 9 is rigidly connected with the central part of the frame 4 and with the driver 10 in the form of a cylindrical pin. When this sleeve 9 can be performed. For example, at the same time with the middle ring of the support bearing 11, which, in its turn, is double-edged with two-sided action. On the side surface of the frame 4, double profiled blades 8 are located and are rigidly connected with it. Bath 4 and Kr 12 have an actuator 14, which is made in the form of a pneumatic cylinder with a stem unfolding as it moves. Such an actuator 14 provides lifting and lowering of the crush 12 with respect to the bath 1. The crush of the crush 12 to the bath 1 for sealing the joint is carried out by means of clamps 13 mounted on its walls. The clamps 13 are made in the form of wedge lever clamps and fix the cover 12 in the closed position. The installation may have several actuators 2 vertical reciprocating movement and rotation. Each actuator 2 may comprise an engine 15, a gearbox 16 and a spindle 17. The engine 15 is designed as a reversible electric motor, mounted on the bath 1 and is rigidly associated with it. Gearbox 16 passes through. the side wall of the bath I and is tightly connected with it by an airtight connection. The lead screw 17 is mounted on supports inside the bath 1 rotatably and, through a gear 16, is connected to the engine 15. The shell 5 is a metal structure in the form of a rigid pan covering the bottom of the frame 4, the central part of which is rigidly connected with the support bearing ring P. In the lower part of the shell 5, nozzle sleeves 6 are installed, the axes of which are directed to the holder 3. Valves 7 are made in the lateral surface of the shell 5 and are spring-loaded the covers working on, type of check valves. At the same time, the valves 7 close when the shell 5 moves down, and when it moves upwards they open. On the outer side of the side surface of the shell 5, bobs 18 are located, the threaded holes of which interact with the driving screws 17 and convert their rotational movement into translational movement. Along the outer surface of the shell 5, in addition to the places where the cobbles 18 are located, there is a seal 19 that seals the joint between the bath I and the shell 5. The seal 19 is made in the form of ribs rigidly connected to the shell 5 and spring-loaded inserts. made of non-metallic half-rings creating a maze. A rod 20 is rigidly connected to the bottom of the bath 1 in the center with a screw groove 21 with an increased angle of lift. The rod-20 is the guiding element of the frame 4 and passes through the bearing 11 and the sleeve 9. In this case, the lead 10 of the sleeve 9 enters the screw groove 21 of the rod 20, converting the post rotational movement into rotational Turbo-collector propellant 22 consists of a crane 23, a collector 24, the drainage pipe 25 and the crane 26; the crane 23 is installed at the entrance to the collector 24 and is shut-off with an electric drive. The collector 24 is located in the lower part of the bath 1 and is designed as a set of annular pipelines with through-holes. The drain pipe 25 is located in the upper part of the bath 1 and is designed as an annular pipe with through-holes, which is protected by a defoaming jacket. A crane 26 is installed at the outlet of the drainage pipe 25 and is constructed similarly to the valve 23. The drainage pipe 25 through the valve 26 communicates with the atmosphere outside the workshop. Pipeline 2 (FIG. 2) connects the internal cavity of bath 1 through valves 28 and 2 to discharge pipes 3 and 31. Valves 28 and 29 are designed as shut-off electro-dampers. The pressure pipe 30 is connected to the top of the cleaner 32 of the washing liquid, and the pipe 31 to the cleaning liquid 33 of the washing liquid. Cleaner 32 provides cleaning and storage of washing liquid, which can be made on the basis of Thermos; . Cleaner 32 (Fig. 3) is made in the form of a container divided by a partition into two parts. Each of the two parts of the cleaner 32 has a conical bottom, connected through a shut-off valve to the sewage system, into which sediment is discharged. The part of the cleaner 32 connected to the pressure pipe 30 is a section for pre-treatment of the fluid and, through a horizontal slot, is connected with an additional capacity of light fractions of contaminants, also connected to the sewage system. Cleaner 32 has a filling port and a steam collector heater. The other part of the cleaner 32 is the final liquid cleaning section and is connected through a hole in the upper part of the partition to the pre-cleaning section. A refill tank is installed on the wall of the final cleaning section of the cleaner 32, the volume of which corresponds to the volume of liquid to be filled into the bath 1. The filling tank is connected through the float valve to the final cleaning section and to the pipeline 34. The inlet of the cleaner 32 connected to the pipeline 30 , is located higher than its inlet hole with a pipe 34, which in turn exceeds the maximum liquid level in bath 1. Cleaner 33 of the washing liquid is made identical to cleaner 32. An aqueous solution of potassium dichroic acid (chromium) can be used as the flushing liquid. Pipeline 34 (FIG. 2) is connected via valve 36 to the inlet of pipeline 30, and pipe 35 through valve 37 is connected to the inlet of pipeline 31. Pipelines 34 and 35 provide liquid by gravity due to the level difference in the bath 1. Valves 36 and 37 are similarly valves 28 and 29. The unit for washing products works as follows. The uncleaned parts come from the process food to the loading table, where they are placed in holder 3. From the loading table, the manure holder takes the holder 3 with the unclean details and carries it to the bath 1, with which the valve is open. The manipulator drops the holder 3 into the inside of the bath 1 at the bottom of the frame 4, which is in the up position at this moment. Then the actuator 14 with rotation lowers the cover 12, and the clamps 13 presses it against the bath I, sealing the joint. After closing the lid 12, the bath 1 is filled with cleaning liquid to a predetermined volume. When the bath 1 is filled with the washing liquid, the drives 2 are turned on for vertical reciprocating movement and rotation. The motors 15 of the drives 2 through the gears 16 are driven into rotation by the driving screws 17, the rotation of which causes the shell 5 to move downward due to the lowering of its bosses 18 along the screw cutting of the screw screws 17. Lowering down, the shell 5 through the support bearing 11 carries away the frame 4, the sleeve 9 of which is lowered along the rod 20 and the lead 10 slides along its screw slot 21, the sleeve 9, the lead 10 and the bearing 1 convert the translational movement of the shell 5 into the rotational movement of the frame 4 with its simultaneous translational movement with the holder 3. Simultaneously with the activation of the actuators 2, the crane 23 of the turbocompletion displacement body 22 opens. The heated air through the collector 24 enters the washing fluid, creating the effect of a boiling, turbulent liquid. From the inner cavity of the bath 1, the air penetrated through the drainage pipe 25 and the valve 26 of the displacer 22 is opened. When the shell 5 is lowered and sealed by a labyrinth seal 19, the fluid in front of it is compressed, which causes the pressure of this fluid to increase. and to the closing of the valves 7. The presence of the passage nozzle bushing 6 on the side 5 causes liquid to flow through them. The energy of the liquid is converted here into the kinetic energy of the jets. Air passing through the liquid enters the forming jets, and all of them are air bubbles. The nozzle sleeves 6 form a system of turbulent jets directed and penetrating the rotating frame 4 with the holder 3. This leads to intensive removal of contaminants from the surfaces of the parts and their removal from the inner zone of the holder 3. Rotating, the frame 4 with its profiled blades 8 and the parts in the holder 3 capture the adjacent layers of liquid, drawing them into rotational motion. Under the action of centrifugal forces, the fluid in this layer along with the contaminants moves to the periphery of the frame 4, the flow around the part, and the profiled blades 8 capture and direct the fluid inside the frame 4 to the holder 3 with the parts. This creates additional turbulization of the fluid flow, facilitating the removal of contaminants from the surface of parts and their removal from the inner zone of the holder 3. These processes continue until the shell 5 with the frame 4 and with the holder 3 reaches the lower position, after which the engines 15 ivodov 2 is altered direction of rotation of the spindles 17, Simultaneously, the valves 23 and 26 of propellent 22 are closed and the air supply into the tub 1 and output prekraschayuts. At the same time, the shell 5 begins to move upwards, dragging the frame 4 with the holder 3, which abruptly change the direction of rotation to the opposite. Due to the fact that the washing liquid was twisted in a rotational motion, then at the moment of stopping and changing the direction of rotation of the frame 4, the parts move against the movement of the fluid flow. At this moment, the speed of movement of parts relative to the fluid is maximum and decreases as the shell 5 rises and the direction of fluid motion coincides with the direction of rotation of the frame 4. At the same time, the profiled blades 8 with their reverse surfaces of the corresponding direction capture the opposite flows of the rotating fluid, ensuring its abrupt intake frame 4. A powerful flow of turbulent fluid is created, penetrating the holder 3 s.

details Such movement of the frame 4 with a change of rotation at the transition of the extreme position promotes intensive removal of contaminants from the surfaces of the parts and their exit from the holder 3.

After changing the direction of movement, the shell 5 moves upward, passing through itself the fluid that passes through the nozzle sleeves 6 and through the valves 7 opening under the action of the velocity head of this direction. Opening the valves 7 provides a sharp decrease in the hydraulic resistance of the shell 5, which means a better flow of parts with fluid at a higher speed. The rotating frame 4 with its blades 8 draws adjacent layers of liquid into rotational motion of the same direction and, capturing, narravlut inside on the holder 3. This creates a turbulent flow of parts in the holder 3 by the liquid, which ensures the effective removal of contaminants. These processes continue until the shell 5 reaches the top position. To achieve the top position of the elements 5, 4 and 3 engines 15 drives

2 changes the direction of rotation of the spindle screws 17. At the same time, the taps 23 and 26 of the displacer 22 are opened. Changing the direction of rotation of the chassis screws 17 causes the shell 5 to move downward, while the valves 7 are closed on it, and the frame 4 with the holder 3 sharply changes direction rotation to the opposite. The cleaning processes and the withdrawal of contaminants that occur during the change of direction in the upper position, occur similarly to the processes occurring at the transition to the lower end position. After changing the direction of movement, the shell 5 with elements 4 and

3 moves down. The further movement of elements 5, 4 and 3 occurs similarly to the indicated movements with all accompanying processes. Such a reciprocating movement of the shell 5 with the frame 4 and the holder 3 takes place until the liquid is loaded. When a liquid is contaminated, the shell 5 is brought to the upper edge.

its position and stops due to the engine 15 being stopped. Simultaneously with the engine 15 shutting down, the valve 23 expels the J body 22 and the valve 28 is opened. The closed position of the valve 26 on the drain pipe 25 provides for the creation of an overpressure of air in the bath 1. The air pressure is displaced The contaminant along with the contamination from the bath 1 through the pipeline 27, the open valve 28, the discharge pipeline 30 to the cleaner 32 of the washing liquid is filled with contamination. The displacement of a liquid occurs until it leaves the bath I and the pipes 27 and 30 are not propelled by air. Passing through cleaner 32, the washing liquid is cleaned of contaminants, for example, by sludge, etc. and accumulates in its fuel tank. After the final displacement of the contaminated liquid, the valve 23 is closed, and the valve 26 of the propellant 22 is opened, providing an exit

25 of the air from the upper part of the bath 1. At the same time, the valve 36 opens and the cleaned cleaning liquid from the cleaner 32 through the filling pipe 34, the open valves 36, 28 and the pipe 27 enters the bath 1, which is filled to the previous volume, and the valves 28 and 36 are closed.

When the bath 1 is filled with the washing liquid 5, the drives 2 are turned on and the crane 23 is opened. A further reciprocating movement of the shell 5 with the frame 4 and the holder 3 with all the processes 0 occurs according to the indicated scheme. Such replacement of the contaminated washing liquid can occur several times depending on the degree of contamination of the parts in the holder 3. If necessary, 5 other types of washing liquid can be used, which comes from an additional cleaner that is structurally designed similarly to the cleaner 32 0 with an identical connection to the bath 1. After cleaning in the washing liquid and its displacement from the bath I, the parts are subjected to washing. For this, the valve 23 is closed and the valve 26 of the propellant 22 is opened, allowing air to escape from the upper part of the bath 1. Opening the valves 29 and 37 opens the passage to be cleaned.

the washing liquid from the cleaner 33 through the pipes 35 and 27 into the bath 1. The bath 1 is filled with the washing liquid to a predetermined volume, after which the valves 29 and 37 are closed. When the bath I is filled with the washing liquid, drives 2 are turned on. Further reciprocating movement of elements 5, 4 and 3 with all related processes and fluid pressure through pipelines 27 and 31 to the cleaner 33 follow the indicated scheme. At this point, the cleaning of parts in the flushing fluid ends with the stop of the shell 5 in the upper position.

After opening the valve 26, the heated air from the displacer 22 through the valve 23, the collector 24 and the internal cavity of the bath 1 with the holder 3 enters the drainage pipe 25, ensuring the parts are blown and dried. The drying of parts finishes after the valve 23 is closed. Then the parts are removed, for which the clamps 13 release the lid 12, and the actuator 14 raises and leads it to the side, opening the bath 1. The manipulator catches the holder 3 from the bottom of the frame 4 and transfers it to the table discharge, where cleaned and dried parts are removed from the holder 3, which are then fed to the process stream. The manipulator then returns to the loading table, where. captures prepared holder 3 with uncleaned parts. Further installation work is repeated according to the indicated procedure.

The invention allows for high-quality cleaning of parts, which is achieved using a combined cleaning, including

5 include the following operations: washing the holder with the parts in a turbulent fluid flow; washing of the holder with parts in various working fluids; jet washing

O ku with a pulsating supply of air into the jet of liquid centrifugal cleaning; final cleaning in the washing liquid; final air blown preheated air hom. All this allows you to completely clean the parts with great performance and immediately release them from the bath to the process flow. Cleaning parts with removal of contaminants from

The 0 bath zone allows the cleaning rate to always be kept at the same maximum level, regardless of the number of parts washed and the time the fluid is used.

5 This allows you to fully use the cleaning fluids in the washing process and maintain the desired concentration. The kinematics of the movement of the drives allows the entire volume of the fluid to pass through the sorter with parts, which significantly increases the cleaning efficiency. The high degree of variable turbulization of fluid flow ensures the complete ignition of the internal surfaces of parts of any configuration without the formation of stagnant zones inside the sorter and the rapid removal of contaminants. The tight implementation of the bath in combination with the removal of liquid and air-blown parts at the end of cleaning for the first time makes it possible to completely eliminate the interaction of the washing liquid vapors with the atmosphere of the workshop.
