Hydraulic suspension type impeller aerator

Abstract

Hydraulic suspension type impeller type aerator, the impeller includes a connecting plate and a wheel, and the wheel includes an inner wheel and an outer wheel, and the connecting plate, the inner wheel, and the outer wheel are connected in sequence from the inside to the outside; the center of the connecting plate A rotating shaft positioning hole is provided, and a group of bolt connection holes are correspondingly provided on the periphery of the rotating shaft positioning hole of the connection plate; a group of balance holes evenly distributed along the circumference is provided on the inner wheel disc, and the circumference is concentric with the inner wheel disc; A group of shovel-shaped blades are evenly arranged on the edge along the circumferential direction, and a group of axial force balance structures are evenly arranged on the outer disc along the circumferential direction; the axial force balance structure consists of long vertical plates, short vertical plates and Balance tendon composition. After the axial force balancing structure is arranged on the outer disc along the circumference, it can balance the axial force caused by the pressure difference and the axial force caused by the dynamic reaction force, making the operation of the aerator more stable and reliable.

Description

technical field [0001] The invention relates to the technical field of aeration equipment, in particular to a hydraulic suspension type impeller aerator. Background technique [0002] The aerator is a machine often used in the aquaculture industry. Its main function is to increase the oxygen content in the water to ensure that the fish in the water will not be hypoxic. At the same time, it can also inhibit the growth of anaerobic bacteria in the water and prevent the deterioration of the pool water from threatening the living environment of the fish. Aerators generally inject air into the water to increase the oxygen content in the water. Aerators are divided into impeller aerators, waterwheel aerators, water spray aerators, inflatable aerators, suction aerators and eddy current aerators, among which the impeller aerators have Oxygenation, water stirring, gas explosion and other comprehensive functions are currently the most widely used aerators, and their oxygenation capa...

AI Technical Summary

Problems solved by technology

[0003] 1) When the aerator is running, the draft depth increases, the equipment load increases, and the motor is easy to burn

[0004] 2) In order not to burn the motor, the motor insurance factor must be increased, resulting in the need to equip a larger power motor, high equipment cost, and high operating costs

[0005] 3) The aerator must use enlarged bearings or bearings that can withstand axial force, resulting in complex equipment structure

The existing method of opening a hole in the center can only solve the axial force caused by the pressure difference but not the axial force caused by the dynamic reaction force. Therefore, it is necessary to develop an impeller type that can balance the axial force caused by the dynamic reaction force. Aerator
