Submersible aerator

Abstract

The invention belongs to the technical field of aquaculture machinery, in particular to a submersible aerator, which mainly comprises a floating body, a submersible motor, bases, an air inlet passage and the like, wherein the floating body is two connected floating pontoons subjected to blow molding at one time, and the two floating pontoons are respectively provided with a through hole capable of penetrating an air inlet pipe; the air inlet passage is that: lower parts of the two air inlet pipes are respectively fixed on connectors of left and right bases, base air ducts are formed in the bases, upper ends of the base air ducts are provided with the connectors of the air inlet pipes, lower ends of the base air ducts are communicated with hinged seats; hollow shafts on two sides of an induction chamber are hinged in the hinged seats; inner holes of the two hollow shafts are communicated with an inner cavity of the induction chamber; a large end of the induction chamber is connected with a shaft outlet end of the submersible motor; a hollow impeller is arranged on a motor shaft; and during work, the submersible motor drives the hollow impeller to rotate to push water to form negative pressure so as to suck air, and the air enters the water through the air inlet pipes, the base air ducts, the hinged seats, the hollow shafts of the induction chamber, induction passages and impeller air ducts.

Description

technical field [0001] The invention belongs to the technical field of aquaculture machinery, in particular to a submersible aerator. . Background technique [0002] The aerator is a life-saving and stimulating equipment for fish and shrimp in aquaculture. Existing mechanical aerators mainly include three types: water wheel type, impeller type and water spray type. There is also a submersible aerator which is connected to the intake pipe by two pontoons and brackets. The intake pipe is bent and welded to the flange. There is also a submersible aerator for a pontoon, which is not stable enough during work. The above two submersible aerators all have complex structures, poor motor seals, and short service life. Contents of the invention [0003] The object of the present invention is to overcome the defects of the prior art and provide a submersible aerator with simple structure and reliable sealing performance of the motor. [0004] The purpose of the present invention i...
