Description

Technical Field

[0001] This utility model relates to the field of micro-nano bubble generating device technology, and in particular to a melting tank for a micro-nano bubble generating device. Background Technology

[0002] The gas melting tank plays a role in converting stored gas into micro-nano bubble generators. Authorized publication number CN201720466360.X discloses a pressure tank for a micro-nano bubble generator, including a tank body and an inlet and outlet connected to the tank body. The inlet is equipped with a microporous baffle, and the tank body is also equipped with several microporous meshes, which are at least two layers thick. A vent valve is installed on the tank body.

Utility Model Content

[0003] (a) Technical problems to be solved

[0004] The technical problem to be solved by this utility model is to provide a melting tank for a micro-nano bubble generator, which uses a water-gas mixing tube to initially mix water and gas, so that it can enter the next process more quickly.

[0005] (II) Technical Solution

[0006] The technical solution adopted by this utility model to solve the above problems is:

[0007] A melting tank for a micro / nano bubble generator includes a tank body, inside which a water-gas mixing pipe is disposed; inside the water-gas mixing pipe a high-pressure water flow pipe is disposed, one end of the high-pressure water flow pipe extending to the outside of the tank body and the other end extending to the inside of the water-gas mixing pipe;

[0008] The water-air mixing pipe is formed from top to bottom into a water-air mixing section and a high-pressure water flow pipe extension section; a gas inlet pipe is provided on the side wall corresponding to the high-pressure water flow pipe extension section of the water-air mixing pipe.

[0009] In the above technical solution, the water sprayed from the high-pressure water pipe and the gas sprayed from the gas inlet pipe enter the tank together along the water-gas mixing section and undergo preliminary mixing in the water-gas mixing section.

[0010] Furthermore, a perforated mesh plate is provided between the inner wall of the tank and the outer wall of the water-gas mixing pipe. The perforated mesh plate has multiple small holes, each with a diameter of 3mm-5mm.

[0011] In the above technical solution, after the water-air mixture enters the tank, it is then cut and mixed by a porous mesh plate.

[0012] Furthermore, the porous mesh plate is provided in two or more layers and is arranged from top to bottom along the length of the water-air mixing pipe. The upper porous mesh plate is inclined at a certain angle inside the tank, the middle porous mesh plate is arranged perpendicular to the length of the water-air mixing pipe inside the tank, and the lower porous mesh plate is symmetrically arranged based on the middle porous mesh plate and the first layer of porous mesh plate.

[0013] In the above technical solution, setting up multi-layered and relatively inclined perforated mesh plates can more fully and effectively mix and cut the water-air mixture.

[0014] Furthermore, the high-pressure water flow pipe includes a water outlet end, which is configured as a cone that is thinner at the top and thicker at the bottom; the outer diameter of the high-pressure water flow pipe is smaller than the inner diameter of the water-air mixing pipe.

[0015] In the above technical solution, setting the water outlet as a cone helps improve the stability of the water flow. This design can reduce eddies in the water flow during the jetting process, improve the concentration and speed of the water flow, and since the high-pressure water flow pipe is set inside the water-air mixing pipe, when the water flow is jetted out at high speed, the internal pressure inside the water-air mixing pipe decreases, thereby increasing the flow rate of the gas entering the pipe. The effect is optimal when the outer diameter of the high-pressure water flow pipe is smaller than the set value of the inner diameter of the water-air mixing pipe.

[0016] Furthermore, the diameter of the gas inlet pipe is smaller than that of the high-pressure water flow pipe.

[0017] In the above technical solution, the narrow pipe of the gas inlet pipe can increase the gas flow rate and avoid excessive gas waste.

[0018] Furthermore, the end of the water-air mixing pipe extends inward and connects to the outer wall of the high-pressure water flow pipe.

[0019] In the above technical solution, connecting the end of the water-air mixing pipe to the outer wall of the high-pressure water flow pipe can prevent leakage.

[0020] Furthermore, an outlet is provided at the bottom of the tank.

[0021] In the above technical solution, the water-air mixture is cut, and after mixing, it enters the next process through the outlet.

[0022] (III) Beneficial Effects

[0023] Compared with the prior art, the technical solution of this utility model has the following advantages:

[0024] (1) The gas melting tank for micro-nano bubble generating device provided by this utility model uses water and gas sprayed out under high pressure to perform preliminary mixing in the water-gas mixing section. After preliminary mixing, the water-gas mixture is cut by a porous mesh plate, which generates more and smaller bubbles, making the micro-nano bubble generation effect faster and better.

[0030] The water-air mixing pipe 2 is formed from top to bottom into a water-air mixing section 7 and a high-pressure water flow pipe extension section 8; a gas inlet pipe 5 is provided on the side wall corresponding to the high-pressure water flow pipe extension section 8 of the water-air mixing pipe 2, and the diameter of the gas inlet pipe 5 is smaller than that of the high-pressure water flow pipe 6.

[0031] A porous mesh plate 3 is provided between the inner wall of the tank body 1 and the outer wall of the water-air mixing pipe 2. The porous mesh plate 3 has multiple small holes, each with a diameter of 3mm-5mm. The porous mesh plate 3 is provided in two or more layers and is arranged from top to bottom along the length of the water-air mixing pipe 2. The upper porous mesh plate 3 is inclined at a certain angle inside the tank body 1, the middle porous mesh plate 3 is arranged perpendicular to the length of the water-air mixing pipe 2 inside the tank body 1, and the lower porous mesh plate 3 is symmetrically arranged with the middle porous mesh plate 3 and the first layer of porous mesh plate 3.

After the water-gas mixture enters the tank 1, it passes through the porous mesh plate 3. At this time, the water-gas mixture has been fully mixed and cut by the multi-layer porous mesh plate, and finally falls to the bottom of the tank 1 and enters the outlet 9 to reach the next process.
