Problems solved by technology

The mixing of coagulant or flocculant and water is usually used in a mixing and stirring device. When adding coagulant or flocculant to the device, due to its large specific surface area and light weight, it is easy to cause dust to fly and bring trouble to the operator. It is inconvenient, and at the same time, the mixing of coagulant or flocculant and water is not uniform, and there will be impurities such as coagulant or flocculant in the water that are not completely dispersed. Easy to clog the delivery pump

Abstract

The invention discloses a sewage treatment dry powder wet agent adding device free of dust leakage and thorough in dispersion, and belongs to a mixer in the technical field of water treatment. The device is mainly formed by an agent dissolving tank, a liquid storage cavity, an air stirring device and an exhaust device and is characterized in that 1, an agent powder dispersing link and a pump conveying link are separated through the agent dissolving tank and the liquid storage cavity; 2, multi-center pneumatic stirring is utilized or combined with mechanical stirring; 3, negative pressure is formed in the agent dissolving tank. Compared with the prior art, the device has the advantages that 1, pump blocking is avoided by designing the agent dissolving tank and the liquid storage cavity; 2,by means of multi-center pneumatic stirring or combination of multi-center pneumatic stirring and mechanical stirring, agent powder and water are dispersed thoroughly; 3, by means of the negative pressure of the agent dissolving tank, the dry agent powder which is not wet by spraying cannot flutter out of an agent adding chute opening, and inconvenient influence on an operator is avoided.

Description

technical field [0001] The invention relates to a mixer in the technical field of water treatment, in particular to a mixer with gas agitation. Background technique [0002] With the development of human society, the development and utilization of water resources are deepening day by day, leading to the increasingly severe situation of water resource shortage and water environment pollution. Water resource shortage and water environment pollution have become global problems today. Therefore, more and more attention has been paid to the prevention and control of water pollution, and various sewage treatment technologies have been continuously developed and applied. Among them, coagulation and sedimentation technology has been developed for a long time, and it is still an important part of water treatment technology. [0003] Coagulation and sedimentation technology is a common method for deep purification of sewage by using coagulants and flocculants. Coagulants or flocculan...
