Impeller water-spraying oxygen-increasing machine

Abstract

The invention discloses an impeller water-spraying oxygen-increasing machine, wherein a motor (11) is arranged above a support body (2), the support body (2) is connected to one end of a support rod (5) in a trisection mode, the other end of the support rod (5) is provided with a floating ball (9), a shaft of the motor (11) is provided with an impeller shaft (14) through a coupler (13), and the impeller shaft (14) is provided with an impeller (18). The impeller water-spraying oxygen-increasing machine is characterized in that a water outlet body (16) is arranged below the support body (2), the impeller shaft (14) penetrates through the centre of the water body (16), a water inlet cover (8) is arranged below the water outlet body (16), and the impeller (18) is positioned in a cavity formedby the water outlet body (16) and the water inlet cover (8). A spiral membrane on the water-outlet body enables the spraying water to be in a rotation state so that the water can contact with the airfor a longer time, the water and the air are further mixed, convection and exchange of a bottom-layer water body and an upper-layer water body are realized, and the oxygen-increasing capability is improved.

Description

technical field [0001] The invention relates to an aerator, in particular to an impeller water spray aerator. Background technique [0002] At present, with the large-scale development of aquaculture and the implementation of central financial subsidies for fishery machinery products, fishery machinery has been vigorously promoted and used, and the aerator has become an indispensable farming machinery in the aquaculture industry. The existing impeller aerators in the market are basically composed of motor, gear reducer, impeller, support rod and floating ball. Certain noise, gears are easy to wear, once the gear oil in the gear reduction box leaks, it will cause water pollution in fish ponds, the impeller will be overloaded and burned when the depth of the impeller exceeds the draft line, and the impeller will cause damage to the fish body. Defects such as inability to fully use; the water wheel aerator can only be used in the field of special aquaculture, because of its lo...

Problems solved by technology

The existing impeller aerators in the market are basically composed of motor, gear reducer, impeller, support rod and floating ball. Certain noise, gears are easy to wear, once the gear oil in the gear reduction box leaks, it will cause water pollution in fish ponds, the impeller will be overloaded and burned when the depth of the impeller exceeds the draft line, and the impeller will cause damage to the fish body. Defects such as not being able to be fully used; the water wheel aerator can only be used in the field of special aquaculture, because of its low aeration capacity, it cannot meet the needs of fish pond aquaculture, and the structure is complex, the quality is large, and the price of the gear reducer is high. Oil will leak and cause water pollution in fish ponds, and even cause the death of cultured animals; the existing water jet aerators use submersible motors, which have a high failure rate, are prone to water leakage and tripping, and the motors are easily damaged. Demand in the field of density farming
