Description

The invention relates to installations for washing and drying various components and parts after machining, as well as before painting and preservation.

A device for washing products is known in which, in order to reduce the installation size and reduce auxiliary time, the table on which the part is placed is combined with a hinged loading hatch that closes the chamber entrance in the working position.

The disadvantage of this machine is the ability to process parts in only one environment, while modern technology for high-quality cleaning requires at least two environments and drying. In addition, with the combined version of the loading hatch and the table, due to the specific trajectory of the part

when entering the chamber, its loading is limited to low or cone-shaped parts, and the presence of parts in the form of a cube or cylinder significantly increases the internal volume of the chamber, which leads to an increase in energy loss during evaporation of the solution, increases the distance from nozzles to cleaning surfaces, and decreases efficiency cleaning, leads to an increase in the diameter of the table, which, in turn, does not allow for horizontal loading-unloading of this table with modern automatic reloading devices.

Known multi-medium washing machine, in which the washing sections with different solutions are tightly separated from each other, which is achieved by making the upper part of the machine in the form of a cap with dead flats | about

birthmarks. Washing circuits with power nozzles are mounted on the entire inner surface of the hood sections. During operation, the hood covers the items being washed, moving in a vertical plane.

The disadvantage of this machine is the impossibility of efficiently washing the body parts of a complex bowl-shaped form due to the absence of movement of the parts relative to the washing jets and in the space, which leads to the accumulation of dirt and residues of the washing solution in the cavities of the parts. In addition, the use of hoses for supplying detergent solutions to the chamber leads to their rapid wear and lower reliability of the machine.

A known jet washing installation, selected as a prototype, comprising a chamber with a tilter, a washing circuit, loading tables, a transporting mechanism with pushers and carriages with elements constituting detachable scenes with each other and the pusher. The unit is equipped with bathtubs with washing and flushing solutions and a drying device.

The disadvantage of this machine is the installation of a tilting unit and the presence of carts in the area of jet washing and drying, which leads to premature wear of their mechanisms and moving parts or requires their manufacture from special materials. In addition, this design significantly increases the internal volume of the chamber and, as a result, leads to the same disadvantages as on the above machine.

The aim of the invention is to expand technological capabilities and increase cleaning efficiency.

This goal is achieved by the fact that the known design of the cleaning module comprises a housing, a washing chamber with a sliding cover, a table with a rotary drive and a base, devices for drying, washing and condensation, which are tilted from the axis, as well as a bath of degreasing and washing solutions with hydraulic systems for its supply,

0 through ventilation duct 40, dispensing device 41 through the baths of degreasing and flushing solutions with a reciprocal receiving branch pipe 42.

The apparatus for cleaning products operates as follows.

The capsule chamber 10 with a sliding cover 32 is in its original vertical and open state. The processed object by horizontal reloading

0 device (not shown conventionally) is shifted to the rotary table 18 so that its T-shaped protrusions, the entry into the T-shaped grooves of the locking device 19 to the stop 20. The reloading device is removed 5 from the camera 19, the sliding cover 32 under the action of the power the cylinder 31 moves down and closes the chamber 10. The rotation drive 11 abuts against the hinged base 12 and around the axle shafts 13 and bearings

0 14 tilts chamber 10 90 ° - puts it in a horizontal working position. In this case, the connecting windows for supplying 22 and removing hot air 23 and the connecting drain pipe 24 of the chamber 10 are joined 5 with the corresponding response windows 35 and 36 of the drying system 34 and the receiving pipe 42, the distribution device 41 through the baths of degreasing and washing solutions, and the telescopic knee the suction of the vapor-air mixture 25 enters the counter-elbow of the ventilation 40 of the condensation system 39.

The dispenser 41 switches to drain the degreasing solution

5 into the degreasing bath 1. The pump 3 is turned on and delivers the washing solution from the degreasing bath 1 through the check valve 4, the supply system 2 passing through the hollow shaft 13 and the collector 26 of the chamber 10 to the object to be processed. Crafted

the degreasing solution is drained from the workpiece into the pan 21 and through the docked drain pipes 24 and 42 and the dispenser 41 flows into the degreasing bath 1, the check valve 8 of the washing solution 6 system is closed.

Upon completion of the degreasing process, pump 3 stops and a similar flushing process occurs. The dispenser 41 switches into layers in the wash bath 5. The pump 7 is turned on and delivers the wash solution from the wash bath 5 through the open check valve 8, the feed system 6 passing through the hollow shaft 13 and the wash manifold 26, of the chamber 10 to the workpiece. The spent washing solution is collected in a pan 21 and through the docked drain pipes 24 and 42 and the dispenser 41 flows into the washing bath 5, the check valve 4 of the degreasing system 1 is closed.

To prevent mixing of the solutions between the degreasing and washing operations, the washing manifold 26 is purged with compressed air - a purge circuit is not shown conventionally.

During the degreasing and washing periods, the Kot sensing system 39 operates, removing the excess vapor-air mixture from the chamber 10 through the manifold 28, the duct 29, the telescopic 25, and the elbow 40.

Upon completion of the flushing process, the pump 7 is stopped, the condensation system 39 is turned off and a drying process takes place. The fan 37 is turned on and supplies air through the heating air heater 38, through the docked windows 22 and 35, the air duct 30, the collector 27 to the object being processed, drains it and is removed from the chamber 10 through the window 16 and the docked windows 23 and 26 of the drying system 34 back to the fan torus 37 onwards in that order.

During degreasing, washing and drying modes to increase processing efficiency, the workpiece is rotated together with the turntable 18 by means of a rotary drive 17, and the rotation is performed 90 ° to both sides from the initial position, which ensures high-quality washing of the product from all sides and at the same time allows to exclude additional fastenings of the object in the locking device 19.

Upon complete completion of all processing modes, the chamber 10 is rotated by the drive 11 to its initial vertical position, the sliding cover 32 is moved upward by the power cylinder 31, thereby releasing the processing object.

The processing facility is removed from the chamber 10 by a reloading device,

the cycle is completed.

The use of the unit for cleaning the PTZ camera allows to increase the cleaning efficiency, and the removal of most moving devices and mechanisms

from the working chamber to increase reliability. The use of an automatic locking device allows automatic loading and unloading of the processed object. Securing the camera to a hinged base reduces the overall volume of the camera, thereby reducing energy consumption.
