specific Embodiment I

[0057] Such as Figure 1~2 , the oscillating assembly 3 includes: an oscillating plate 301 and more than two return springs 302; wherein, the oscillating plate 301 is closer to the bottom of the aeration tank than the output end of the aeration assembly 2; the return spring 302 is arranged on the Between the oscillating plate 301 and the output end of the aeration assembly 2, it is used to provide a vibrating restoring force for the oscillating plate 301; the oscillating plate 301 is flat or faces the bottom of the aeration tank.

[0058]The return spring 302 can be selected according to needs. At the same time, in order to increase the impact force, the oscillation plate 301 adopts a flat plate shape. The water flow output by the aeration assembly 2 hits the plate-shaped oscillating plate 301 vertically. Since the aeration assembly 2 is generally output by an impeller, the water flow output from the output end of the aeration assembly 2 is not a constant flow rate, resulting...

specific Embodiment II

[0060] Such as image 3 Since the flat plate-shaped oscillating plate 301 is used in the specific embodiment 1, after the water flow containing large air bubbles hits the plate-shaped oscillating plate 301, too many fine air bubbles exist near the oscillating plate 301. During the movement, the oxygen is basically exhausted, and the aeration effect is not ideal.

[0061] In order to solve the above-mentioned problems, on the basis of the specific embodiment I, the oscillating plate 301 adopts an arc-shaped plate, and the arc-shaped plate protrudes toward the bottom of the aeration tank.

[0062] The water flow output by the aeration assembly 2 impinges on the arc-shaped oscillating plate 301. Since the aeration assembly 2 is generally output by an impeller, the water flow output from the output end of the aeration assembly 2 is not a constant flow rate, resulting in abnormal After the water flow at a constant velocity hits the oscillating plate 301, the oscillating plate 301 ...

specific Embodiment III

[0066] Such as Figure 4 , in order to increase the application reliability of the submersible aerator of the present invention, a submersible aerator also includes: a control unit 4, an air pump 5 and a counterweight 6; wherein the control unit 4 is arranged on the bracket assembly 1; the air pump 5 is arranged on the support assembly 1, and is used to forcefully inject air into the liquid in the aeration assembly 2; the counterweight 6 is used to balance the support assembly 1; the control unit 4 and the air pump 5 Electrically connected, used to control the air pump 5 to force ventilation according to the oxygen content in the aeration tank.

[0067] The oxygen content in the aeration tank is detected manually or electronically. If the oxygen content is too low, the control unit 4 controls the air pump 5 to work to perform forced ventilation and increase the oxygen in the aeration tank.

[0068] Preferably, the air pump 5 supplies air to the aeration tank through an air no...

Abstract

The invention aims to provide a submersible aerator and a use method thereof, and the submersible aerator comprises a support assembly, an aeration assembly and an oscillation assembly; wherein the support assembly floats on the water surface; the aeration assembly is arranged on the bracket assembly and is used for spraying liquid rich in bubbles from the output end of the aeration assembly underthe action of the aeration assembly; the oscillation assembly is arranged at the output end of the aeration assembly and is used for continuously adjusting the distance between the oscillation assembly and the output end of the aeration assembly according to the flow velocity of the liquid at the output end of the aeration assembly. The oscillating assembly is arranged at the output end of the aeration assembly, so that the oscillating assembly continuously adjusts the distance between the oscillating assembly and the output end of the aeration assembly according to the flow velocity of liquid at the output end of the aeration assembly, a vibration effect is generated, more fine bubbles are generated, and the basic area of liquid in the aeration tank is increased.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to a submersible aerator and a use method thereof. Background technique [0002] The aeration tank is a structure that uses the activated sludge method for sewage treatment. The aeration tank is mainly composed of three parts: the tank body, the aeration system and the water inlet and outlet. The pool body is generally made of reinforced concrete, and its planar shape is rectangular, square and circular. The aeration tank provides a certain sewage residence time to meet the oxygen required by aerobic microorganisms and the mixing conditions for full contact between sewage and activated sludge, thereby decomposing various organic matters in the water, which is beneficial to the next step of the process. [0003] The submersible aerator is directly driven by the motor and the impeller, and the air is mixed with the liquid by the rotation of the impeller to form a uniform ...
