Flocculating agent dissolving equipment for sewage treatment tank

Abstract

The invention relates to the technical field of sewage treatment, and discloses flocculating agent dissolving equipment for a sewage treatment tank, the flocculating agent dissolving equipment comprises a machine body, the inner bottom end of the machine body is fixedly connected with a lower cavity, the middle part of the inner bottom end of the lower cavity is fixedly connected with a rotating assembly, and the movable shaft of the rotating assembly is movably connected with the top end of the lower cavity in a sleeving manner; the top end of the rotating assembly located outside the lower cavity is fixedly connected with two stirring rods, a stirring block is arranged at the top end of one stirring rod, and a square hole is formed in the middle of the top end of the machine body. The stirring block is arranged at the top end of one stirring rod, so that the stirring rod drives the blocking assembly on a main plate to swing to open the discharging hole in the rotating process, and a flocculating agent located in a feeding part equivalently falls into the machine body at a constant speed to be mixed with an aqueous solution; the flocculating agent is effectively prevented from being agglomerated or blocked too much due to too much or too fast one-time addition, and the dissolving efficiency of the flocculating agent is improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a flocculant dissolving device used in sewage treatment pools. Background technique [0002] Flocculant is a substance that can cause solutes, colloids or suspended particles in water to produce floc precipitation. It is widely used in many fields such as urban sewage, building materials wastewater, hospital sewage, petrochemical wastewater, papermaking waste liquid, pharmaceutical wastewater, etc. In the sewage treatment, the sewage can meet the water quality requirements of a certain water body for drainage or reuse, which has the advantages of promoting water quality clarification, reducing the amount of sludge, and making the filter cake easy to handle. [0003] Some flocculants cannot be directly added to the sewage, they must be dissolved in water before use, and then their aqueous solution is added to the sewage in a certain proportion. However, during the dissol...
