Problems solved by technology

[0002] In the actual production process, it is found that most of the existing filters cannot meet the requirements when the polymer organic thermal solution is separated from the solid and liquid.
One is that the polymer solution requires multi-stage filtration, while most of the existing filters are single-stage
The second is that the polymer solution needs to be kept warm during the whole process of filtration. The existing filter has a large temperature loss and is difficult to keep warm.
The third is that the polymer solution is an organic solvent and must be sealed during the filtration process, and open filtration equipment cannot be used

Abstract

The invention discloses a multistage filtering device for a polymer organic solution, and belongs to the field of filtering. The device includes a base, a first-stage sealing cylinder that is arrangedon the base, the filtering motor that is arranged on the bottom side of the first-stage sealing cylinder, the second-stage sealing cylinder that is arranged in the first-stage sealing cylinder and connected with the output end of the filtering motor, the multiple sets of filtering net cylinders that are arranged in the second-stage sealing cylinder and are coaxially arranged, and the heating setthat is arranged between the first-stage sealing cylinder and the second-stage sealing cylinder. According to the invention, the multi-stage filter screen cylinder is designed in the second-stage sealing cylinder to realize one-time multi-stage filtering, the heat preservation effect is good, the temperature loss is small, and the filtering effect and the filtering efficiency of the polymer organic solvent are greatly improved.

Description

technical field [0001] The invention relates to the field of filtration, in particular to a multistage filtration device for polymer organic solution. Background technique [0002] In the actual production process, it is found that most of the existing filters cannot meet the requirements when the polymer organic thermal solution is separated from the solid and liquid. One is that the polymer solution requires multi-stage filtration, while most of the existing filters are single-stage. The second is that the polymer solution needs to be kept warm during the whole process of filtration. The existing filter has a large temperature loss and is difficult to keep warm. The third is that the polymer solution is an organic solvent and must be airtight during the filtration process, and open filtration equipment cannot be used. Contents of the invention [0003] The present invention is aimed at the deficiencies in the prior art, proposes a kind of multistage filtration device f...
