The existing problem is that the mixing tank contains large particles of dust and water vapor, which enter the filter through the vacuum pipe. The filter is easily blocked and has a short service life. In the production process, sudden blockage requires shutdown to replace the filter element, causing great losses. It is relatively difficult to predict the blockage time, and the cost of regular replacement of the filter element is high. Summary of the invention

[0032] The working process of this utility model:

[0033] a. Install a long-life mixer vacuum filtration system that does not require stopping to replace the filter element on the mixer. A controller is set on the mixer. When the vacuum filtration loop is working, when the vacuum filter 14 in the vacuum main line 1 is blocked, the pressure at the outlet increases, and a pressure difference is formed between the inlet and outlet of the pipeline. The first ball valve 15 is opened, and the temporary branch line 2 is connected. The equipment can temporarily operate normally, and at the same time, the equipment issues an alarm to replace the filter element, reminding you to replace the filter element;

[0034] b. The operator can directly replace the filter element while the equipment is running after closing the first ball valve 15 on both sides of the vacuum filter 14 in the vacuum main line 1.
