[0005] To achieve the above-mentioned purpose, the technical scheme adopted by the utility model is as follows:

[0006] A filter for the production of chemical auxiliaries includes a filter body. An inlet pipe is fixed to the outside of the filter body, and a reducing pipe is welded to the outer opening of the inlet pipe. A flange is fixed to the outer pipe of the reducing pipe away from the inlet pipe. The filter body also includes a reducing mechanism, which comprises a fixed ring, a primary reducing pipe, a tail ring, a middle buffer cylinder, a bucket seat, a tail bundle pipe, and corner plates A and B. A fixed ring is fitted into the outer opening of the reducing pipe, and a primary reducing pipe is fixed within the fixed ring. The body of the primary reducing pipe is inserted into the reducing pipe, and a tail ring is fixed behind the primary reducing pipe. A middle buffer cylinder is screwed onto the tail ring, and its body is inserted into the inlet pipe. A tail bundle pipe is welded to the end of the middle buffer cylinder away from the tail ring via a bucket seat, and the tail bundle pipe extends into the filter body along the inlet pipe.

[0007] Furthermore, the corner plate A is symmetrically fixed with arc connecting plates on both sides, and the arc plate body of the arc connecting plate is welded to the inner wall of the initial shrink tube.

[0008] By adopting the above technical solution, after the corner dividing plate A is welded and fixed inside the initial shrink tube with the help of the arc connecting plate, the corner dividing plate A can divide the cavity at the initial shrink tube into a small cavity.

[0009] Furthermore, the corner plate B is symmetrically fixed with arc-shaped plates on both sides, and the arc-shaped plate body is welded to the inner wall of the middle cylinder.

[0010] By adopting the above technical solution, the corner plate B is welded and fixed inside the intermediate cylinder with the help of the arc plate, and the corner plate B can divide the intermediate cylinder into small cavities.

[0011] Furthermore, a screw-on hole is provided at the part of the cylinder body away from the bucket seat of the intermediate slow cylinder, and a tail ring is screwed into the screw-on hole;

[0012] By adopting the above technical solution, the tail ring can be screwed onto the intermediate cylinder through the screw-on hole, thereby completing the connection between the intermediate cylinder and the initial shrink tube.

[0013] Furthermore, the top of the corner plate A faces the outer opening of the reduced diameter pipe, and a back bend rib groove is provided on the plate body of the corner plate A.

[0014] By adopting the above technical solution, when chemical auxiliary production materials enter the reduced diameter pipe, the chemical auxiliary production materials can be separated at the corner dividing plate A, and the corner dividing plate A has a back bend rib groove for reinforcement.

[0018] This invention features a diameter reduction pipe at the inlet pipe of the filter body, along with a diameter reduction mechanism. The diameter reduction mechanism, consisting of a primary diameter reduction pipe, a secondary buffer cylinder, and matching corner dividing plates A and B, effectively pre-divides and guides the chemical auxiliary materials entering the filter. The materials first pass through the small dividing cavities of the primary diameter reduction pipe and corner dividing plate A, then enter the secondary buffer cylinder through the tail ring, and are further divided by corner dividing plate B. This process increases the pressure and flow rate of the materials, which helps to better distribute the materials within the filter and improves filtration efficiency.

[0019] Furthermore, the design of the diameter reduction mechanism and the corner plate not only increases the dispersibility of chemical auxiliary production materials, but also increases the flow path of the materials to differentiate the flow, thereby increasing the impact force of the materials on the inner wall of the filter and improving the filtration effect of the chemical auxiliary production materials at the filter body.
