Impeller of oxygen-enriching machine

Abstract

The invention relates to an impeller of an oxygen-enriching machine. The impeller comprises an impeller disc and a plurality of blades arranged on the impeller disc; a straight tube penetrating through the center of the impeller disc is fixed onto the impeller disc; the multiple blades are distributed on the outer side wall of the impeller disc in the circumferential direction of the straight tube; the impeller further comprises an annular check ring located at one side of the outer side wall of the impeller disc, and an enclosing plate; the annular check ring is arranged at the outer edge inthe circumferential direction of the impeller disc; the enclosing plate, the annular check ring and the side wall of the straight tube jointly define a cavity; the multiple blades divide the cavity into a plurality of mixing chambers; the annular check ring is provided with multiple sets of water outlets; multiple sets of air inlets are formed in the impeller disc; a plurality of water inlets areformed in the inner wall of the straight tube; and the water inlets communicate with the corresponding mixing chambers. When the impeller rotates, water continuously touches and mixes with new air entering into the mixing chambers in the process that the water flows from the water inlets to the water outlets, so that water flows is rich in air, and the mixing degree of the water and the air is improved to make oxygen enriching efficiency higher.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to an aerator impeller. Background technique [0002] The aeration machine is a commonly used machine in the fishery and aquaculture industry. It drives the working parts through a power source such as an electric motor or a diesel engine, so that the "oxygen" in the air is quickly transferred to the equipment in the aquaculture water body. The machine is mainly used to increase The oxygen content in the water can ensure that the fish and other organisms in the water will not be hypoxic, and 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 island fish. [0003] At present, the Chinese patent with the notification number CN201536562U discloses an aerator impeller, including a wheel body and spokes, the spokes are fastened on the wheel body, the wheel b...

AI Technical Summary

Problems solved by technology

However, although the impeller of the aerator can push a large amount of water to move, the contact time between the water body and the air is short, and the air that can actually enter the water body is limited, resulting in poor oxygenation effect
