Description

TECHNICAL FIELD

[0001] The application relates to the technical field of retention and drainage aids, in particular to a high-molecular retention and drainage aid stirrer. BACKGROUND

[0002] The retention and drainage aid is a chemical agent made of a polyacrylamide derivative. The polyacrylamide is widely used as a papermaking aid. Cationic polyacrylamide is used to utilize the negative electric property of the filler surface in the papermaking retention process, to cationize the filler surface with a cationic high-molecular polyelectrolyte, to increase the adsorption of the filler particles, paper pulp fibers and fine fibers, to improve the single-pass retention rate of the filler, to reduce the filler content in the white water, to reduce the loss and thus reduce the cost, to reduce the concentration and ash content of the pulp on the wire, to prolong the service life of the forming wire, and to improve the smoothness and opacity of the paper sheet.

[0003] Patent No. CN219291258U discloses a high-molecular retention and drainage aid stirrer. The high-molecular retention and drainage aid stirrer simultaneously feeds two different raw materials into two liquid inlet pipes. A motor drives the mixing hopper to rotate, so that the two raw materials can be mixed in the mixing hopper, fall into the cylinder, and then be stirred by the stirring paddle to mix the raw materials above the cylinder and stir the raw materials below the cylinder, so that the mixing of the raw materials is more uniform and efficient. However, the preliminary mixing effect of the different raw materials in the mixing hopper is not ideal. In actual use, the raw materials flow down along the inner wall of the mixing hopper into the stirring link, which increases the production cost of the stirrer and reduces the performance-price ratio of the stirrer.
