Micro-sized small-power impeller-type aerator

Abstract

The invention relates to a micro-sized small-power impeller-type aerator. The micro-sized small-power impeller-type aerator comprises a floating body, an electromotor and an impeller. The floating body is made by vinyon. The floating body is of a hollow-core circular ring with a low and recessed edge and a low and recessed middle part. The impeller is arranged in the center of the floating body. An electromotor is arranged below the floating body. The impeller is connected with a rotary shaft of the electromotor. The impeller is composed of a rotor body and multiple blades. The rotor body is arranged in the middle and the blades are uniformly distributed around the rotor body along the peripheral direction. The blades are of inverted-trapezoidal structures. The blades are obliquely welded on the external circumference of the rotor body. The blades are driven by the electromotor such that water flows are lifted from downward to the oblique top and splashed to the air, thereby forming water mist. Compared with the prior art, the micro-sized small-power impeller-type aerator has the following beneficial effects: the micro-sized small-power impeller-type aerator is simple in structure and convenient in installation; water flows can be directly lifted from downward to the oblique top and splashes are formed so that the effect of Increasing oxygen and dissolving oxygen is exerted; and the micro-sized small-power impeller-type aerator is widely applied to the field of production device for domestic aquatic products so that the amount of dissolved oxygen is improved and breeding effect of aquatic products is effectively improved.

Description

[0001] [technical field] [0002] The invention relates to the technical field of aquatic aeration equipment, in particular to a miniature low-power impeller type aeration machine. [0003] [Background technique] [0004] At present, among various submersible electric pumps and various aquaculture machinery and equipment on the market, the commonly used ones mainly include impeller aerators and gushing aerators. Among them, the impeller type aerator, the motor is equipped with a reducer and installed on the bracket after assembly, and then the bracket is installed on three floating balls, and a 1:11 reducer is installed at the shaft end of the motor, and the shaft extension of the reducer drives the impeller The disc rotates in the water at a speed of 136r / min to drive up the water splashes and promote the flow of water waves to increase the amount of dissolved oxygen in the water. Its structure is complex and bulky. The gushing type aerator installs a water pump on the upper ...

Problems solved by technology

Among them, the impeller type aerator, the motor is equipped with a reducer and installed on the bracket after assembly, and then the bracket is installed on three floating balls, and a 1:11 reducer is installed at the shaft end of the motor, and the shaft extension of the reducer drives the impeller The disc rotates in the water at a speed of 136r / min to drive up the water splashes and push the water waves to flow to increase the amount of dissolved oxygen in the water. Its structure is complex and bulky

The gushing type aerator installs a water pump on the upper part of the motor, and installs a nozzle at the outlet of the water pump. The water is squeezed out from the gap. After spraying out, the oxygenation range is only a circular range, and the water volume is very small. Insufficient oxygenation capacity and low power efficiency

Therefore, above-mentioned aerator all can't satisfy the special demand of small-scale farmer, if can provide a kind of miniature low-power impeller type aerator, make it have simple and reliable structure, water yield is big, oxygen-increasing capacity is sufficient, and power efficiency is high, will Can achieve certain economic and social benefits
