[0002] Wet strength agent is mainly used in the papermaking industry. It is a new generation of non-toxic and odorless papermaking additives commonly used in the world that can greatly improve the dry and wet strength of paper sheets. When using, first pour the wet strength agent into the container according to the dosage, dilute it 5-10 times with cold water, stir evenly, and slowly add it to the post-grinding pool or pulping pool.
[0003] In the production of wet strength agent, various chemical agents need to be stirred and mixed by a mixing device. The mixing devices in the prior art all perform mixing by stirring. However, during the stirring process, most mixing devices use a single stirring blade for stirring. This method causes the liquid to form a vortex during the stirring process, which causes the axial flow to be destroyed. All the chemical agents flow in the form of radial flow fluid, making it impossible for chemical agents at different levels to mix with each other, thereby reducing the mixing effect, resulting in insufficient mixing and insufficient practicality. Therefore, it is necessary to redesign a liquid mixing device for wet strength agent production in view of the above problems. Utility Model Content

The lifting mechanism comprises a cylinder 4 fixedly mounted on the upper end surface of the first support plate 3, and the telescopic end of the cylinder 4 is fixedly connected to the bottom wall of the connecting plate 5. The cylinder 4 telescopes up and down to drive the cover plate 6 to move, so as to facilitate the opening and closing of the cover plate. The end of the connecting plate 5 is fixedly connected to the cover plate 6 that matches the upper end surface of the mixing tank 1, and a moving frame 7 is fixedly mounted on the bottom wall of the cover plate 6. A reciprocating screw 8 is rotatably mounted on the inner wall of the moving frame 7, and a motor 9 connected to the reciprocating screw 8 is fixedly mounted on the upper end surface of the cover plate 6.
