Description

A gas-liquid mixing device

technical field

The utility model relates to a mixing generating device, in particular to a gas-liquid mixing generator device for mixing gas in liquid.

Background technique

The gas-liquid mixing generator is the core device of the aerator. At present, the traditional gas-liquid generators on the market mainly include the following types: One is the jet flow type, which forms a water flow to stir the water body to increase oxygen gently, and is suitable for fish fry pond aeration. Oxygen; the second is the waterwheel type, which has a good effect of increasing oxygen and promoting water flow, and is suitable for ponds with deep silt; the third is the impeller type, which has comprehensive effects such as increasing oxygen, stirring water, and aerating, and is currently the most used Its aeration capacity and power efficiency are superior to other models, and it is generally used for large-scale pond cultivation with a water depth of more than 1 meter. The general impeller type just uses the impeller to stir the water to make the water contact with the gas to achieve the purpose of dissolving the gas in the water, but the gas dissolving efficiency is not good.

Patent No. ZL200520100530.X (Notice No. CN2791034Y) utility model patent "Aeration Head for Aerator" discloses an aeration head for increasing oxygen. The negative pressure absorbs the gas, and the gas is cut by the aeration rotor and passes through the dispersing claws. At the same time, the dispersing claws agitate the water flow driven by the propeller impeller for the second time, so that the gas and the water flow are mixed. However, this kind of aerator only absorbs gas through negative pressure, resulting in insufficient gas volume during gas-liquid mixing, and the generated bubbles are also relatively thick, resulting in an unsatisfactory oxygenation effect of the gas-liquid mixture.

Utility model content

The purpose of the utility model is to provide a gas-liquid mixing generating device to improve the oxygen-increasing effect and gas-dissolving efficiency of the gas-liquid mixture.

In order to solve the above technical problems, the technical solution adopted by the utility model is as follows.

A gas-liquid mixing generating device, the hub of the spiral nylon impeller 5 is provided with an inner cavity; the spiral nylon impeller 5 is provided with small blades located in the inner cavity; The inner cavity is connected and constitutes the suction channel; the copper insert 4 and the inner diameter of the spiral nylon impeller 5 are fixedly connected by the insert; the shaft 2 and the copper insert 4 are arranged on the shaft 2 and the copper insert 4 through the connecting key 3 The keyway of the spiral nylon impeller 5 is axially fixed with the center line of the shaft 2 through the spring washer 6 and the nut 7; connect.

The number of blades of the spiral nylon impeller 5 is three.

There are 6 small blades inside the spiral nylon impeller 5 .

The gas bubble network 9 is hemispherical.

The utility model has beneficial effects. The utility model improves the air intake efficiency through the negative pressure generated by the rotating impeller and the small blades added inside; and refines the air bubbles through the rotating cutting effect of the gas bubble network to improve the gas dissolution efficiency.

Detailed ways

Below in conjunction with accompanying drawing and specific example the utility model is described in detail.

The overall structure of the gas-liquid mixing generator is shown in Figure 1. The air intake cover 1 connected with the driving and rotating device communicates with the inner cavity and forms an air suction channel; the copper insert 4 and the inner diameter of the spiral nylon impeller 5 are fixed by inserts; the shaft 2 and the copper insert 4 are connected by The key 3 is matched with the keyway provided on the shaft 2 and the copper insert 4; the spiral nylon impeller 5 is provided with an inner cavity; the spiral nylon impeller 5 is provided with small blades located in the inner cavity; Nylon impeller 5 is axially fixed with shaft 2 through spring washer 6 and nut 7 ; The gas bubble network 9 is provided with evenly distributed small holes, as shown in FIG. 4 .

The structure of the air intake cover 1 is shown in FIG. 2 .

The number of blades of the spiral nylon impeller 5 is three, as shown in FIG. 3 .

The number of small blades inside the spiral nylon impeller 5 is 6, as shown in FIG. 3 .

The gas bubble network 9 is hemispherical, as shown in FIG. 4 .

The working process of the utility model is: when the shaft 2 drives the spiral nylon impeller 5 to rotate at a high speed to promote the water flow movement, a negative pressure will be generated near the gas bubble network 9 to inhale, and the air intake cover 1 communicates with the inner cavity of the impeller hub At the same time, the small blades in the inner cavity of the hub of the spiral nylon impeller 5 also push the gas to move towards the gas bubble network 9, and the gas passes through the rotating impeller at high speed under the double action of negative pressure and small blades. The gas bubbles into the mesh 9 to form finer bubbles, which are mixed with the water flow driven by the spiral nylon impeller 5 to achieve the purpose of gas-liquid mixing.
