Symmetrically arranged propeller type self-air compression, self-air suction and self-water absorption aerator

Abstract

The invention discloses a symmetrically arranged propeller type self-air compression, self-air suction and self-water absorption aerator. A motor fixed on a weight beam transmits power to a hollow shaft through a chain, and an internally helical blade conical air compression wheel with a through hole at bottom is arranged on the upper end face of the hollow shaft. A hollow sleeve is sleeved outside the hollow shaft, the upper end face of the hollow sleeve is connected with the weight beam, the other end of the weight beam is fixed with a floater, the lower end face of the hollow sleeve is connected with an air suction chamber, the tail end of the hollow sleeve is provided with a driving bevel gear, and two driven bevel gears are arranged on respective hollow output shafts respectively. The other ends of the hollow output shafts extend out of the air suction chamber, the tail ends of the hollow output shafts are provided with an impeller and a diffuser, and the extended part comprises the impeller and the diffuser and is enclosed by a deflector fixed on the air suction chamber. The water suction pipe, after entering from the bottom face of the air suction chamber, is divided into two parts, and the divided two pipes extend into the hollow output shafts respectively. In the invention, the air compression wheel is used for compressing air, the impeller is used for air suction, and the air intake volume is high; the adoption of the air suction pipe increases the air and liquid mixing and shearing action; and the aeration capacity is increased.

Description

technical field [0001] The invention relates to an aerator, in particular to a symmetrically arranged propeller-type self-compressed air, suction and water aerator. Background technique [0002] Aerator is a machine that is often used in fishery and aquaculture, so that the "oxygen" in the air is quickly transferred to the aquaculture water. It can not only solve the problem of fish floating heads caused by lack of oxygen in pond culture, but also can Eliminate harmful gases, promote convective exchange in water bodies, improve water quality conditions, reduce feed coefficients, and increase fish pond activity and primary productivity, thereby increasing stocking density, increasing the feeding intensity of breeding objects, promoting growth, and greatly increasing the yield per mu. purpose of increasing income. The measures taken when designing the aerator are: 1) Use mechanical components to stir the water body to promote convective exchange and interface renewal; 2) Disp...
