Abstract

The invention belongs to the technical field of sewage treatment equipment and discloses a spiral jet aerator. The spiral jet aerator is used for solving the problem that the air dissolution efficiency is low in the conventional aerator. The spiral jet aerator disclosed by the invention comprises a water pump, wherein the water pump is connected with an aerator; the aerator comprises an air suction chamber and a nozzle; the nozzle is sleeved by one end of the air suction chamber; the other end of the air suction chamber is connected with a throat tube; the air suction chamber is further communicated with an air suction tube; spiral guide plates are arranged inside the nozzle; multiple through holes are formed in nozzles between adjacent spiral guide plates; the air suction tube is connected with at least two air inlet branch tubes; the air inlet branch tubes sleeve the periphery of the nozzle; the air inlet branch tubes are uniformly provided with air inlets of which the number is the same as that of the through holes; and the air inlets are communicated with the through holes by virtue of pipelines. The spiral guide plates are arranged inside the nozzle, and the air inlet branch tubes are arranged at the periphery of the nozzle, so that air is introduced into the nozzle, and the air can be rapidly dissolved in water. Therefore, the air dissolution efficiency of air is improved, and the sewage treatment effect is improved.

Description

[0001] technical field [0002] The invention belongs to the technical field of sewage treatment equipment, and in particular relates to a spiral jet aerator. Background technique [0003] The aerator injects "micro-bubbles" directly into the untreated sewage through the diffuser impeller. Under the joint action of the coagulant and flocculant, the suspended solids undergo physical and chemical flocculation, thereby forming large suspended solids. The floc, under the action of the buoyancy of the bubble group, the "floc" floats to the liquid surface to form scum, which is separated from the water by a scum scraper; there is no need to clean the nozzle, and no clogging will occur. [0004] For example, the utility model patent with application number 201420707321.0 discloses a water pressure energy gradient utilization jet aerator, including a submersible pump, a double-air channel annular nozzle primary suction jet, a multi-nozzle radial secondary jet aerator, Mixed liquid ...
