Polyaluminum chloride water purification device and working method

Abstract

The invention discloses a polyaluminium chloride water purification device and a working method. The polyaluminium chloride water purification device comprises a device main body, a rotating motor isfixedly mounted on the front side surface, close to a corner, of the device main body, and a driving shaft penetrating through the device main body is mounted at the output end of the rotating motor;and a driving gear fixedly sleeves the outer side face, close to the other end, of the driving shaft, a sawtooth belt is arranged on the side face, away from the rotating motor, of the device body andclose to the bottom, a driven gear is installed on the side face, close to the sawtooth belt, of the device main body and located at one corner, and a driven shaft is arranged in the driven gear in apenetrating mode. Powder and sewage can be fully mixed through double shafts, the time required for impurity flocculation is shortened, the sewage purification efficiency is improved, the situation that a pipeline is blocked due to the fact that polyaluminum chloride powder adheres to the pipe wall is avoided, a good anti-blocking effect is achieved, the powder is prevented from flying to the inner wall of the device, and the utilization rate of powder is improved.

Description

technical field [0001] The invention belongs to the technical field of polyaluminum chloride water purification, in particular to a polyaluminum chloride water purification device and a working method. Background technique [0002] Polyaluminum chloride is an inorganic polymer coagulant. Due to the bridging effect of hydroxide ions and the polymerization of polyvalent anions, it produces an inorganic polymer water treatment agent with a large molecular weight and a high charge. It can be divided into solid and liquid, and the solid can be divided into brown, yellow and white according to the color. Polyaluminum chloride of different colors also has great differences in application and production technology; [0003] The existing polyaluminum chloride water purification device still has certain defects in use. In most cases, the powder is directly poured into the sewage for mixing, and a single roller is used for stirring, the mixing effect is poor, and the time required for ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a polyaluminum chloride water purification device and working method, which mainly solves the defects that the existing polyaluminum chloride water purification device still has certain defects in use, and in most cases, the powder is directly poured into the Mixing in sewage, using a single roller for mixing, the mixing effect is poor, and the time required for the flocculation of impurities is longer, thereby reducing the purification efficiency of sewage, and the polyaluminum chloride powder is easy to adhere to the pipe wall and cause pipe blockage. It does not have a good anti-clogging effect, and the powder is easy to float to the inner wall of the device, which reduces the utilization rate of the powder
