(54) INSTALLATION FOR LIQUID CLEANING OF PARTS (57) The invention relates to mechanical engineering and can be used in various processes with liquid treatment of parts, specifically to clean parts from contaminants and quenching media after heat treatment. The purpose of the invention is to simplify the design and operation of the device. The goal is achieved due to the fact that the sealed container 1 has a sealed cover 17 at the top and is equipped with a pipe 9 connecting the sealed container with an open tank 10, and one discharge pipe is equipped with a shower system 19 inside the sealed container, and the other a suction pipe 3 in place connection with. the sealed container contains a reflector 20 made in the form of a plate rigidly mounted at an angle to the outlet of the pipeline. 1 s.p. f-ly, 1 ill.

The invention relates to mechanical engineering and can be used in various processes with liquid machining of parts, and more particularly to cleaning parts from contaminants and quenching media after heat treatment.

The purpose of the invention is to simplify the design and operation of the device.

The drawing shows a device, jq General view.

The installation consists of a sealed container 1, pump 2 with a suction 3. and discharge 4.5 pipelines with valves 6, 7, 8. respectively.> 5

The pressurized container 1 is connected by a pipe 9 passing through its bottom with an open tank 10 located under the pressurized container 1. The upper end of the pipeline 9 is located above the liquid level in the pressurized container 1, and the lower one is buried below the liquid level in the re-energy 10. The pipeline '9 is equipped with a shutter 11, the tank 10 is equipped with a tray 25 T2 for filling the liquid, and the pipeline 5 is equipped with a filter 13. The cleaned parts 14 are placed in a sealed container 1, which has a pipe 15 with a shutter .16 and a sealed container 1 on top. a sealed cover 17 is installed, in which a valve 18 is installed, and the pipe 4 ends in a sealed container 1 with a shower system 19. The pipe 3 is equipped with a reflector 20 made ^ 5 in the form of a plate rigidly mounted at an angle to the pipe inlet. To drain contaminants, the sealed container 1 is connected by a pipe 21 to a pipe 15. The pipe 21 contains a shutter 22.

Installation works as follows.

Through the airtight cover 17, parts 14 are placed in the airtight container 1. The airtight container 1 is filled with liquid (washing solution) when the airtight cover 17 is removed from an external source until the airtight container 1 is completely filled when the pipelines 3, 4, are closed. 5, 9, 15, 21 with gates 6, 7, 8, 11, 16, 22, respectively. After filling the liquid in the sealed container 1, the cover 17 is hermetically closed. When the shutter 6 is opened, the pump · 2 is turned on, and the liquid from the sealed container 1 enters through the filter 13 into the discharge pipes 4, 5. Then, when the shutter 7 is gradually opened, the liquid is supplied through the pipe 4 to the shower system 19 for washing parts 14, and when the shutter is opened 8 through the pipeline 5 - to the tank 10. In this case, the liquid level in the sealed container 1 decreases, a vacuum is formed and the liquid enters (is sucked) through the pipe 9 into the sealed container 1 from the open tank 10. In the pipeline 9 and the sealed container 1 a significant amount of reduced pressure (vacuum) is given, which is provided stable, without cavi-. tatsii, the operation of the pump 2, installed with a negative suction height (under the bay); the presence of the pipeline 9; connecting the cavity of the tank 10 and the tight container 1, and with a larger length of the pipeline there is a large vacuum (theoretically, the difference in the marks of the liquid levels in the sealed container 1 and the tank 10 to 10 m):

n = ^π βακ $>

where Η _vak is the height of the liquid column;

~ vacuum pressure;

y is the volumetric weight of the liquid. Deepening the edges of the pipeline 9 to the liquid level in the tank 10 eliminates the suction of air (the formation of a suction funnel).

I

Thus, with the simultaneous mixing of the liquid and the formation of a vacuum in the sealed container 1, intensive formation and release of air bubbles occurs. A part of the bubbles settles on the surface of the parts 14, including in places difficult to access. After washing, when the pump 2 is stopped, the sealed container 1 through the valve 18 communicates with the atmosphere. At this moment there is an intensive removal of air from parts 14 in the form of bubbles, which contributes to the destruction of contaminants and their removal from the surface of parts 14, this ensures high-quality cleaning and washing of parts 14. To prevent dirt from entering the suction pipe 3 at the entrance to him, in the tank 1, a reflector 20 is installed. A light fraction of contaminants that floats to the surface of the liquid during the washing process is removed into the sewer through the pipe 21 when the shutter 23 is opened. the solutions settled in the lower part of the sealed container 1, after the end of the washing process, merge through the pipe 15 when the shutter 16 is opened for discharge (into the sewer). To drain possible mud impurities from the liquid, a filter 13 is installed in the pipeline 5. The washed and cleaned parts 14 are removed from the sealed container 1 when the sealed cover 17 is opened. ''

The device operates in automatic mode - the pump 2 is turned on and off depending on the liquid levels, and the gates are equipped with electric drives (not shown in the drawing).

Thus, during the simplification and operation of the device, washing and cleaning of contaminants and hardening media is carried out while creating a vacuum and mixing the layers of liquid), and for this it is enough to have one unit of energy consumption - a pump.
