SU631774A1 - Stand for cleaning heat pipes - Google Patents

Description

The invention relates to devices for cleaning, washing containers with a mapped inlet section, for example, tepp tubes.

There are known washing devices that contain a container of water, which is attached to the product being washed by means of a pipeline through a pulsator with a check valve and a nozzle apparatus, which are connected with a compressed raaaflj

A device for cleaning products is known, comprising a bath with a wash liquid and a vibrator with a grill, on which a workpiece 2J is placed.

However, the known devices have a low rate of flushing, cleaning of heat pipes, as they are intended for flushing of water pipes, and there is no intensive liquid circulation in the baths, because the heat pipe is a closed vessel with a small inlet section. Oi there is also no degassing of the internal cavity of the product after cleaning.

The purpose of the invention is to increase the intensification of the cleaning process, mainly of tanks with a mapped inlet section.

This is achieved in that a stand-off system for washing liquid from the tubes, including a drainage tank, is introduced into the stand, which contains a container with washing liquid, a pipeline for connecting to the tubes, a pulsator with a check valve and a nozzle, connected to the compressed gas line, and a crane. made in the form of a nitrogen trap, and a vacuum pump connected to it, the drainage tank has a reset pin and the valve is made in the form of a vacuum valve.

The drawing shows a schematic diagram of the stand.

The stand contains a container 1 with liquid connected to the product to be washed 2 by means of pipe 3. The pipeline is equipped with a pump 4 with a return valve 5 and a nozzle device 6, ioTo-roe are connected through valve 7 with a cylinder 8 of compressed gas, as well as valve 9

363 To relegal 2, a suction system is turned on, which includes a valve 10 and a valve 11 to protect the mechanical vacuum pump from breaking through the atmosphere and the compressed Lod gas with a pressure, nitrogen poke 12 (drainage tank), which is connected through the valve 11 to a mechanical vacuum pump 13 The nitrogen trap 12 is fitted with a valve 14 for draining the fluid and for relieving the pressure of the system. 2; mounted on vibrator 15 and in order to prevent vibrations from being transmitted to the circuit element of the unit, compensators 16 are installed. The stand operates as follows. They turn on the mechanical vacuum on soy 13, supply nitrogen to the nitrogen trap 12. Open the valves 11, 10, i.e. Nitrogen production and pumping out of product 2 vushki 12. Close valve U, open valve 9, and the liquid from tank 1 1 through pulsator 4 with non-return valve 5, nozzle device 6 and valve 9 enter into product 2, on which vibratory overloads are imposed from V1 Rostand 15, After a certain time, the valve 11 is closed, the valves 7, 10 are opened. When the valve 7 is opened, the compressed gas under pressure of 4-5 atm. from the baplon 8, it enters the cavity of the pulsator 4 and closes the check valve 5, i.e. it stops the flow of liquid from the tank 1. The liquid remaining in the pulsator 4 is squeezed by gas into the nozzle 6, in which a liquid-gas emulsion is formed, and through valve 9 is injected into product 2, valve 14 is opened, and the release goes through valve 10, nitrogen trap 12 74 and valve 14. Then valves 7, 14 are closed and valve 11 is opened, i.e. the process is repeated. After several cycles with the valve closed: the valve 7 closes the valve 9, thus stopping the access of liquid and gas to the product 2 and degassing with the valves 10, 11 open, the invention intensifies the cleaning process of mainly containers with a small inlet section and allows for degassing after cleaning. Claims; 1, pTeHjd for cleaning heat pipes, containing a container for washing liquid, a pipeline for connecting with pipes, a pulsator with a check valve and a conn device connected to the main line of compressed gas, and With a chain of intensification of the cleaning process, it is predominantly a tank with a small inlet section, it has a system of suction of washing fluid from the pipe, including a drainage tank and a associated vacuum pump, the drainage tank has a) reset, and the faucet is designed as a vacuum valve . 2.
