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

Embodiment 1

[0045] like figure 1As shown, the separation tank 400 has an acid gas inlet 401 and an acid gas outlet 402, the acid gas introduced by the vacuum pump enters the separation tank 400 through the acid gas inlet 401, and the separation tank 400 separates the acid gas from gas and liquid, and the acid gas after the separation The gas is discharged from the acid gas outlet 402 of the separation tank 400, and the separated vacuum condensate remains in the separation tank 400. A part of the vacuum condensate in the separation tank 400 will be discharged from the sewage pipe 403 at the bottom of the separation tank 400, Part of the working fluid of the vacuum pump is circulated into the pump body of the vacuum pump. The liquid level gauge 300 is used to measure the capacity of the vacuum condensate in the separation tank 400, and is connected to the separation tank 400 through the lead pipe 200. Since the impurities in the acid gas will gradually accumulate in the lead pipe 200, the l...

Embodiment 2

[0056] The second embodiment of the present invention provides an online cleaning method, such as Figure 4 As shown, using the vacuum pump separation tank liquid level gauge online cleaning device in the first embodiment, including the following steps:

[0057] Step S1, remove the liquid level gauge 300 of the separation tank 400, connect the connector 12 of the cleaning cartridge 1 to the lead pipe valve 100 of the liquid level gauge 300, and close the lead pipe valve 100;

[0058] Step S2, open the water inlet pipe 13 through the first control valve 14 of the cleaning cylinder 1, and the cleaning water enters the cleaning cylinder 1;

[0059] Step S3, slowly open the lead pipe valve 100, adjust the first control valve 14, so that the water pressure of the water inlet pipe 13 is not less than 0.1Mpa, until the lead pipe valve 100 is fully opened; The tube 1 enters the guide tube 200 so as to have a scouring effect;

[0060] Step S4, make the rotating rod 21 rotate, the scr...

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...
