Raw material impurity removal device for polyaluminum chloride production

Abstract

The invention provides a raw material impurity removal device for polyaluminum chloride production, and relates to the field of polyaluminum chloride, the raw material impurity removal device comprises a mixing cylinder internally provided with a mixing cavity, a motor fixed at the bottom of the mixing cavity and a chassis mounted on an output shaft of the motor, wherein the upper end face of the mixing cylinder is provided with a plurality of inlets, and the lower end face of the mixing cylinder is provided with a plurality of outlets, a plurality of through holes penetrating through the upper and lower surfaces of the chassis are formed in the chassis; the outer side of the chassis is rotationally connected with a side ring groove formed in the side wall of the mixing cavity; a plurality of stirring rods, wherein the bottom ends of the stirring rods are fixed on the upper surface of the chassis; screens corresponding to the inlets, wherein the screens are mounted under the corresponding inlets; a diluting pipe which is mounted on the upper surface of the mixing cylinder; plug columns corresponding to the through holes, and a driving part which is connected with the plug columns, wherein the diameter of the plug columns is equal to that of the corresponding through holes, and the driving part is used for driving the plug columns to move, so that the plug columns enter the through holes or are far away from the through holes. Through the device, the water purification effect of the produced polyaluminum chloride is ensured.

Description

technical field [0001] The invention relates to the field of polyaluminum chloride, in particular to a raw material removal device for polyaluminum chloride production. Background technique [0002] Polyaluminum chloride is an inorganic polymer coagulant, which is an inorganic polymer water treatment agent with a large molecular weight and a high charge produced due to the bridging effect of hydroxide ions and the polymerization of polyvalent anions. It can be divided into solid and liquid in form. Polyaluminum chloride is mainly used in the field of water treatment, including water purification treatment, such as domestic water, industrial water, urban sewage treatment, industrial wastewater, sewage, sludge treatment and some slag recovery in sewage, etc. [0003] The applicant found that most of the raw material removal devices for the production of polyaluminium chloride on the market do not have the dilution function, because polyaluminum chloride will precipitate fixed...

AI Technical Summary

Problems solved by technology

[0004] In view of this, the purpose of one or more embodiments of this specification is to propose a raw material removal device for polyaluminum chloride production, so as to solve the problem of the existing raw material removal device for polyaluminum chloride production on the market in the prior art. Most of them do not have the dilution function, because polyaluminum chloride will precipitate fixed particles during the production process, which will affect the technical problem of the water purification effect of polyaluminum chloride after production
