Abstract

The utility model discloses a jet aerator, which belongs to sewage treatment equipment. The jet aerator comprises a suction air chamber (1), a tubular mixing chamber (3) and a water inlet pipe, wherein the suction air chamber (1) is communicated with an air inlet pipe; the tubular mixing chamber (3) is arranged below the suction air chamber (1) and is communicated with the suction air chamber (1); and the water inlet pipe is coaxially arranged in the mixing chamber (3) and is provided with a cone spray nozzle (5). The jet aerator is characterized in that the inner wall of the spray nozzle (5) of the water inlet pipe is provided with at least three blades (8) which are distributed in a helical shape. In the utility model, the blades which are distributed in a helical shape are arranged in the spray nozzle of the water inlet pipe, and thus, water flow jetted from the spray nozzle is rotated under the action of the blades, the friction of the water flow and the air is increased and the air bubbles become small, so that sewage is oxygenated uniformly, the dissolved oxygen is high and the aerating effect is greatly improved.

Description

A kind of jet aerator
Technical field
The utility model relates to a kind of sewage disposal device, particularly a kind of jet aerator.
Background technology
In the sewage disposal, jet-flow aeration is as the third aeration mode after blast aeration, mechanical aeration, utilize effusive turbulent fluctuation campaign and shearing action, cutting gas, produce microbubble, obtain high oxygen transfer rate, with and simple in structure, take up an area of to economize, initial cost is few etc., and advantage more and more causes people's attention.Existing jet aerator generally is made up of nozzle, suction chamber, three parts of interfusing chamber, its principle of work is: current form high velocity flow through the nozzle ejection, forming negative pressure around nozzle introduces air, and utilize effusive turbulent fluctuation diffusion that current and air are mixed, form air-water mixture and penetrate.Usually the nozzle of jet aerator mostly is conical structure greatly, and there is the defective that mixed effect is bad, dissolved oxygen amount is little between working medium and the injection medium in this kind nozzle arrangements because working medium is that direct injection is come out, and causes the aeration weak effect.
The utility model content
At the above-mentioned defective that exists in the prior art, the utility model provides a kind of novel jet aerator, and its oxygenation is even, and dissolved oxygen amount is big, and aeration is effective.
The utility model is achieved by the following technical solution: a kind of jet aerator, comprise the suction air chamber that communicates with inlet pipe, be located at and suck the air chamber bottom and suck the piped mixing section that air chamber communicates, the coaxial water inlet pipe that has conical nozzle in the mixing section that is arranged on, the nozzle inner walls of described water inlet pipe are provided with at least three blades of shape distribution in the shape of a spiral.
The utility model is by being provided with the blade of shape distribution in the shape of a spiral in the nozzle of water inlet pipe, make that the effect owing to blade produces rotation to the current that spray at the nozzle place, increased the friction of current and air, the air thorough mixing of sewage and injection, bubble diminishes, the sewage oxygenation is even, and dissolved oxygen amount is big.
In order to improve mixed effect and to consider processing of leaves technology, the blade in the utility model can adopt rectangle or right-angled trapezium shape.
The beneficial effects of the utility model are: the utility model is simple in structure, it is by being provided with blade in spiral distribution in the nozzle of water inlet pipe, make the current that eject in the nozzle can with the air thorough mixing of injection, because the rotation of current, current and air friction diminish bubble, thereby the sewage oxygenation is even, dissolved oxygen amount is big, improves the aeration effect greatly.

Embodiment
Embodiment below by indefiniteness also is further described the utility model in conjunction with the accompanying drawings:
As shown in drawings, shown in the present embodiment is a kind of jet aerator, it comprises the mixing section 3 that sucks air chamber 1, is located at suction air chamber 1 bottom, suck air chamber 1 and be provided with inlet pipe 7, can communicate with inlet system, mixing section 3 is a tubular structure, and it is provided with pore 2 corresponding to the tube wall that sucks air chamber 1, sucks air chamber 1 and communicates by pore 2 with mixing section 3.Water inlet pipe 6 coaxial ends that are arranged on mixing section 3, its water side is positioned at mixing section 3, and the water side has nozzle 5, and nozzle 5 is the tapered tube structure, and its inwall is provided with the equally distributed blade 8 of shape in the shape of a spiral, and shown in the present embodiment is three blades.The other end of mixing section 3 is air water mixed exports 4, and it is the tapered tube structure.
The quantity of the blade 8 in the present embodiment can be adjusted according to the design needs, and the shape of blade 8 can adopt rectangle or right-angled trapezium shape.
Working process of the present utility model is: gas enters from inlet pipe 7 and sucks air chamber 1, sewage sprays at a high speed through nozzle 5 from water inlet pipe 6, forming negative pressure in the sewage course of injection around the nozzle will suck in the air introducing mixing section 3 in the air chamber 1 and mix, oxygenation in water, mixed air-water mixture penetrates through air water mixed export 4.
Other parts of present embodiment adopt prior art, do not repeat them here.
The foregoing description only is used for explanation of the present utility model, is not to its restriction, and those skilled in the art also can make a change on this basis.

Claims (2)

1. jet aerator, comprise the suction air chamber (1) that communicates with inlet pipe, be located at and suck air chamber (1) bottom and suck the piped mixing section (3) that air chamber (1) communicates, the coaxial water inlet pipe that has conical nozzle (5) in the mixing section (3) that is arranged on is characterized in that: the nozzle of described water inlet pipe (5) inwall is provided with at least three blades (8) of shape distribution in the shape of a spiral.
2. jet aerator according to claim 1 is characterized in that: described blade (8) be shaped as rectangle or right-angled trapezium.
