Abstract

The invention relates to the technique of washing and degreasing parts and can be used in mechanical engineering and instrument engineering for cleaning parts with internal and hard-to-reach channels. By restricting the discharge pipelines with partitions and a bottom with a check valve, a compartment is formed in the tank. When the compressed gas is supplied to the compartment, the washing nozzles enter the nozzles of the working chamber, and then the compressed gas. Moreover, the compressed gas enters the volume of washing liquid accumulated in the working chamber, which ensures its bubbling. This improves the quality and performance of the wash. 6 Il.

The invention relates to the technique of washing and degreasing parts and can be used in mechanical engineering and instrument engineering for cleaning parts with internal and hard-to-reach channels from chips and fatty contaminants.

The aim of the invention is to improve the quality and productivity of washing.

FIG. 1 shows the installation, General view; in Fig.2 - the same, side view; in fig. 3 - cleaning the part in a liquid medium with a jet of washing liquid; in fig. 4 - the same, in a liquid medium with compressed air; in fig. 5 - the same, in the air medium with a jet of washing liquid and compressed air; in fig. 6 - discharging the washing liquid from the working chamber into the tank for washing liquid.

The product washer comprises a washing liquid tank 1, equipped with a transparent hose 2 for draining the washing liquid and for measuring its level. A pressure pipe 3 is located in the tank 1. The tank is equipped with partitions 4 not reaching the bottom of the tank and a bottom 5 outgoing from their lower edge, forming a compartment in the tank 1, and the pressure pipe 3 is located in this compartment. A check valve 6 is built into the bottom 5 of the compartment, and the compartment has a nozzle 7 connected to a source of compressed gas. On the tank 1, a working chamber 8 is installed, equipped with a manipulator 9 for transferring the cleaned parts 10 from the storage tray 11 to the receiving tray 12 with nozzles 13 placed on it. The storage tray 11 is equipped with directional nozzles 14 and a damper 15 to smooth the blows when feeding along parts tray, as well as to receive a signal of part availability. A coarse filter 16 is fixed on the working chamber 8 to clean the washing liquid when it overflows through the nozzle 17 or when it is drained through the openings 18 and the nozzle 19. In the upper part of the working chamber 8, the control ultrasound 20 is located, containing a machine control system, such as a microcontroller.

Installation for washing products works as follows.

If there are parts 10 on the storage tray 11, the damper 15 is activated and the part presence signal is fed to the console 20. The compressed gas is turned on through the fitting 7. The valve 6 is closed and the washing liquid is fed to the nozzles 13 and 14 through the discharge pipe 3. the tank 1 and the passage for the required period of time through the pipe 3 and the nozzles 13 and 14 of the compressed air providing a bar of washing liquid in the chamber, the source of compressed air is turned off. The fitting 7 is connected to the atmosphere. Under the action of the hydrostatic pressure of the liquid, the tank 1 opens, the valve 6 and the compartment are filled with liquid. The manipulator 9 is turned on and transfers the part 10 from the storage tray 11 to the receiving tray 12, where it is finally cleaned with directional jets of washing liquid and compressed air. The following detail falls on the damper 15. The cycle is repeated. During the operation of the machine, the washing liquid from the washing chamber 8 is poured through the pipe 17 and

filter 16 coarse to tank. The washing chamber 8 is emptied by moving the coarse filter 16 to the front end position. Fluid through the holes 18 and the pipe 19, and the filter 16 enters the tank 1. The fluid from the tank 1 is drained through the hose 2.

The use of the proposed device for washing products will make it possible to drastically improve the quality of cleaning body parts with hard-to-reach channels and blind holes compared to the existing ones, reduce the cost of manual labor for cleaning parts, and free up production areas.
