Description

Technical Field

[0001] The utility model relates to the technical field of water treatment equipment, in particular to a flocculant uniform dispensing device for water treatment. Background Art

[0002] Flocculant is a high molecular polymer that can form floccules from fine solid particles dispersed in liquid. It is mainly used in wastewater treatment systems. Currently, conventional sewage treatment generally includes coagulation, sedimentation, filtration and disinfection. Coagulation is the first step in conventional water treatment technology. Its purpose is to add flocculants to neutralize some particles or particles with negative (positive) charges in the water that are difficult to separate, reduce their electric potential, make them unstable, and use their polymerization properties to concentrate these particles and separate them by physical or chemical methods.

[0003] However, in the traditional flocculant dissolution process, the more traditional flocculant mixing method is still used, that is, the flocculant is directly added to the water to be treated in proportion for stirring. During the addition process, since the flocculant is added in a concentrated manner in a short period of time, agglomeration and uneven dissolution are prone to occur, which affects the later use effect of the flocculant. Therefore, a water treatment flocculant uniform distribution device is urgently needed to solve the above problems. Utility Model Content

[0004] 1. Technical issues to be solved

[0018] The beneficial effect of adopting the above further scheme is that by starting the servo motor to make the worm drive the worm wheel to rotate, the hollow drum drives the stirring rod to stir slowly, avoiding the stirring rod from breaking the formed alum flowers too quickly.
