Online cleaning device and online cleaning method for liquid level meter of vacuum pump separation tank

Abstract

The invention belongs to the technical field of vacuum pumps, and discloses an online cleaning device and an online cleaning method for a liquid level meter of a vacuum pump separating tank, and the online cleaning device for the liquid level meter of the vacuum pump separating tank comprises a cleaning cylinder and a movable scraper assembly; one end of the cleaning cylinder is open, the other end of the cleaning cylinder is provided with a bottom plate with a guide hole, the opening is provided with a connecting piece used for being connected with a liquidometer guide pipe valve, and the cleaning cylinder is provided with a water inlet pipe used for inflow of cleaning water and a first control valve arranged on the water inlet pipe; the movable scraper assembly comprises a rotating rod and a scraper structure, one end of the rotating rod rotatably penetrates through the guide hole, the other end of the rotating rod is fixedly connected with the scraper structure, and the scraper structure is used for rotating and propelling to penetrate through the guide pipe valve and clean the inner wall of the guide pipe. According to the online cleaning device for the liquid level meter of the vacuum pump separating tank, the guide pipe can be cleaned online, the pump does not need to be stopped, the liquid level meter is prevented from being distorted, and the production efficiency is prevented from being influenced; according to the online cleaning method, the device is applied to online cleaning of the guide pipe, the cleaning steps are simple, and the cleaning efficiency is high.

Description

technical field [0001] The invention relates to the technical field of vacuum pumps, in particular to an online cleaning device and an online cleaning method for a liquid level gauge of a separation tank of a vacuum pump. Background technique [0002] A vacuum pump refers to a device that uses mechanical, physical, chemical or physical-chemical methods to evacuate the pumped container to obtain a vacuum. In order to ensure the vacuum pumping effect of the vacuum pump, a vacuum separation tank is often set for gas-liquid separation to ensure gas purity. . The main function of the vacuum pump separation tank in the smelting industry is to separate the acid gas from gas and liquid. The separated acid gas is discharged from the outlet pipe of the separation tank, and the separated liquid (ie vacuum condensate) is left in the separation tank. Part of the vacuum condensate in the tank is discharged from the sewage pipe at the bottom of the separation tank, and part of it enters t...

Problems solved by technology

Because the acid gas contains impurities, during the operation of the separation tank, the impurities will slowly accumulate in the liquid level gauge lead pipe of the separation tank, causing the measurement distortion of the liquid level gauge, which will make the operation of the vacuum pump unstable, even in the In the case of falsely high liquid level, due to the lack of working fluid in the pump body of the vacuum pump, it will cause damage to the pump body and equipment failure

[0003] At present, the liquid level gauge after the introduction tube is blocked can only be cleaned when the pump is stopped. Generally, if the vacuum pump continues to run for two months, the introduction tube will be blocked and the measurement of the liquid level gauge will be distorted.

If the pump is stopped to clean the liquid level gauge in such a short time interval, it will not only increase the workload, but also frequently reverse the pump will affect the stable operation of the vacuum pump, and ultimately affect the production efficiency and product quality
