Description

Super Rotary Magnetic Oxygenation Aerator

Technical field:

The utility model relates to sewage treatment equipment, in particular to a super-rotating magnetic oxygen-charging aerator.

Background technique:

At present, the discharge of industrial and people's domestic sewage has attracted great attention from all walks of life, and a large amount of sewage discharge has a great impact on the ecological environment. In the prior art, the aeration device is inseparable from sewage treatment, and the quality of the sewage treatment depends on the energy efficiency of the aeration device. The traditionally used (a) surface aerator has a shallow draft and can only aerate on the surface. The amount of oxygenation decreases with the increase of water depth. A large amount of dead sludge is easy to accumulate at the bottom of the pool, forming an anaerobic reaction, which may cause anaerobic Oxygen mud expands and floats up, which seriously affects the sewage treatment effect and consumes a lot of power. (b) The microporous aeration head is matched with the Roots blower. The Roots blower is bulky and needs to build a large machine room. It occupies a large area and consumes a lot of energy. It is necessary to arrange a large number of ventilation pipes at the bottom of the pool. The microporous aeration head is located at the bottom of the pool. , The pores are easily blocked by the deposited activated sludge, and the aeration function is lost, so it cannot be repaired without stopping the production. (c) The jet aerator has a limited draft and sludge is easy to accumulate at the bottom of the pool. These treatment equipments have complex structures, high energy consumption, inconvenient use and maintenance and other deficiencies to varying degrees, which are far from meeting the requirements of existing sewage treatment and discharge.

Invention content:

The purpose of the utility model is to overcome the deficiencies of the prior art and provide a super-rotating magnetic oxygen-charging aerator with simple structure, low energy consumption and convenient maintenance.

The purpose of this utility model can be realized by following technical measures:

The upper and lower parts of the main tube of the super-rotating magnetic oxygenation aerator are respectively connected to the platform and the main engine. The connected inflatable pipe is connected with the flow divider at the bottom, the flow divider is connected with the hollow shaft connected with the ejector at the bottom, and the flow-aid propeller is connected with the outside of the hollow shaft.

The purpose of this utility model can also be achieved through the following technical measures:

A check valve is provided at the junction of the inflation pipe and the diverter; the platform is triangular, circular or regular polygonal; the platform and the floater are connected through a floater connecting rod; the floater is Floating ball; there are several floating ball buoyancy devices.

The utility model is provided with:

Rain cover - installed above the oxygenator, hat-shaped, to prevent the oxygenator from being exposed to rain;

Oxygenator—installed on the platform, connected to the inflation pipe, and sends air to the water;

Oxygenator protective cover - protect the oxygenator from collision and splashing water;

Platform - the upper part is equipped with an oxygenator, and the lower part is connected with a floating ball by a floating ball rod;

Floater connecting rod - connected to the floater, the length can be adjusted to control the depth of the aerator into the water;

Floater - to make the aerator float on the water, which can realize the aerator to float anywhere on the water surface, which can be fixed in place or moved to other places, and the layout is flexible;

Inflatable pipe - the upper part is connected to the oxygenator, and the lower part is connected to the shunt after passing through the check valve, which is the channel for the oxygenator to supply air;

Main cylinder——The upper part is connected to the platform, and the lower part is connected to the main engine. It is the connecting part between the lower structure of the aerator and the platform. It realizes aeration and mixing in deep water. Changing the length of the main cylinder can also adjust the aeration depth;

Main engine—the upper part of the main engine is connected to the main cylinder, and the lower part is connected to the diverter. The structure of the submersible sludge pump casing is adopted to protect the internal motor from water leakage. Mechanical wear and swaying can achieve the effect of increasing the torsional moment and rotating speed, increasing the force of the jet and the force of stirring;

Check valve——the lower part of the inflatable pipe. Due to the high underwater pressure, when the aerator stops working, the water flow will recoil from the inflatable pipe and may be poured into the blower. Therefore, a check valve is added at the lower part. It can be automatically closed when it stops to prevent water recoil;

Diverter—the upper part is connected to the host, the lower outer ring is connected to the magnetizer, the center of the lower part is connected to the hollow shaft, and the side is connected to the air tube. The sealing area gathers into the hollow shaft. When the main engine rotates at high speed, the blowing force driven downward by the air-supply piece is very large, and a negative pressure will be formed in the diverter, which will generate a suction force on the air inlet, so that the air is easy to enter and can reduce the water charge. The power consumption of the oxygen machine overcomes the difficulty of deep water air supply and the huge power of air supply machinery caused by the high underwater pressure;

Magnetizer—distributed and fixed on the frame of the lower outer ring of the shunt, made of NdFeB permanent magnets as the main material, the water flows into the hollow shaft inside after being magnetized by the magnetizer, and many properties of the water body will occur after magnetization Changes are beneficial to the transfer of dissolved oxygen, and the biological activity of activated sludge can be increased by 18%. It is rare to use magnetization technology for sewage treatment;

Hollow shaft——The upper end is connected to the flow divider, and the air enters through it. There is an "inner jet port" in the middle section, and there are water inlet holes on the outer wall. The sewage enters the hollow shaft from the water inlet hole and mixes with the jet air. The hollow shaft continues to jet down to the "super swirl jet";

Flow impeller - divided into main propeller and flow aid propeller, the main propeller is welded on the outside of the middle section of the hollow shaft, above the water inlet hole, and three or more pieces are set according to the needs, the size is larger, and it can push the flow downward and stir The role of the flow aid propeller is welded on the outside of the lower section of the hollow shaft and above the super swirl jet, the size is small, and it plays the role of cutting air bubbles;

Super swirl jet - oblate, hollow, surrounded by cutting blades, the upper part is connected to the hollow shaft, which rotates synchronously with the hollow shaft, and the mixed state of air and water is injected into the super swirl jet from the hollow shaft, and then injected into the water horizontally.

The utility model uses floating balls to float the aerator on the water, and the water platform is connected to the main cylinder downwards. A submersible motor is installed at the bottom of the main cylinder. Jet aeration, the oxygenator on the upper part of the platform is connected to the lower suction jet structure through the air supply pipe to assist air supply. The deep water aeration overcomes the disadvantage of uneven oxygenation of the water body, especially the problem of insufficient oxygenation of the deep water body; the lower part of the jet agitation promotes the full mixing of oxygen, water body and sludge, and avoids sludge deposition at the bottom of the pool Form anaerobic reaction; due to the relatively small volume, there is no need to build a large machine room on the ground, no need to be equipped with large auxiliary equipment, no need to arrange ventilation pipes; in addition, low energy consumption, under the premise of the same oxygenation effect, can be Save energy consumption by 30%.
