If these waste liquids are discharged directly into the sewer, they will not only cause environmental pollution, but also cause great harm to the health of the operators. Therefore, it is very important to collect the waste liquids after the experiment. Chemical laboratories generally use large glass bottles or plastic barrels to store them, but these harmful waste liquids are potentially dangerous when placed in the laboratory.

The application discloses a waste liquid treatment device for laboratories, which adds a filter bin and a baffle on the original basis, the baffle is fixedly connected to the inner wall of the treatment box, and the baffle is arranged at the bottom of the filter bin, so as to set off the filter bin, and the feed hole opened in the middle of the baffle is opened at the bottom of the filter screen, so that the waste liquid after filtration flows into the bottom of the treatment box, and finally the filter bin can be taken out from the inside of the treatment box, and the filter screen at the bottom of the filter bin is cleaned.

[0004] However, this application has certain shortcomings.

[0021] In summary, this application includes the following beneficial technical effects:

[0022] The stirring rod is driven to rotate by two rotating shafts to rotate the inside of the processing box. There are more sealing paths between the rotating shaft and the processing box and the cost is lower. At the same time, the mounting cover can be detached to remove the filter plate, and the filter plate can also be cleaned, so the sealing is better. BRIEF DESCRIPTION OF THE DRAWINGS
