Device for preparing flocculant

Abstract

The invention discloses a device for preparing a flocculant. The device comprises a spiral conveying device, a hydrocyclone, a stirring device and a water purification device; the spiral conveying device conveys quantitative flocculant powder to the hydrocyclone at a uniform speed, eddy current is formed in the hydrocyclone, after being sufficiently mixed with water at a uniform speed in advance,the flocculant powder enters the stirring device to be stirred, and the problems are solved that the manual material adding speed is not uniform, and caking is easily caused when the flocculant powderis not sufficiently mixed in advance; the water is treated through the water purification device, and fine particles in tap water can be reduced, so that the fusing effect of the flocculant is better; a roller is driven by a gear to rollably rotate. On one hand, the problems of an existing stirring mode are solved that flocculant solid sinks at the bottom of a dissolving tank and is not easily stirred; on the other hand, the collision frequency of the flocculant powder and the water is increased by rolling and rotation, and the stirring effect is good.

Description

technical field [0001] The invention relates to the technical field of flocculant dissolution, in particular to a flocculant preparation device. Background technique [0002] Flocculants are mainly used in the fields of water supply and drainage and sewage treatment. The flocculant is mainly a group with positive (negative) charge and some particles or particles with negative (positive) charge in water that are difficult to separate, close to each other, reduce its potential, make it in an unstable state, and use its The nature of aggregation makes these particles concentrate and flocculate into agglomerates, and they are separated by physical or chemical methods to achieve the purpose of cleaning water. At present, the flocculants used in wastewater treatment are generally inorganic flocculant powders, which need to be formulated into flocculant solutions before use. [0003] There are several factors that affect the dissolving flocculant: 1. The water quality used to dis...

AI Technical Summary

Problems solved by technology

The applicant found in actual operation that the problem of artificial feeding is that the addition rate is not easy to control. With the gradual increase of the solution concentration, it cannot be guaranteed that the flocculant powder added later can be fully mixed with the water body at the moment of addition. The uneven speed is very easy to cause a large amount of flocculant powder to agglomerate in the water and it is difficult to mix evenly. A large amount of flocculant blocky waste gathers at the bottom of the dissolving tank, which not only causes waste of resources, but also affects the stability of the flocculant production process, and even cause pipe blockage

[0005] At present, there is no special equipment that can efficiently prepare flocculant solution
