[0002] Cavitation occurs when bubbles or cavities form and grow in a liquid as the liquid pressure changes.

[0003] The most common liquid cavitation equipment now is the Venturi tube. After the water flows into the Venturi tube, when the water flows through the contraction section of the Venturi tube, the water flow cross-sectional area becomes smaller, the water flow velocity increases rapidly, the pressure decreases, cavitation bubbles are generated in the water, and cavitation occurs at the throat position of the Venturi tube.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] The utility model provides Figure 1-2 The cavitation enhancement device shown includes a connecting pipe 101, a first cavitation mechanism and a second cavitation mechanism. The outer wall of the connecting pipe 101 is provided with an air intake mechanism, and the interior of the connecting pipe 101 is provided with a rotating mechanism. The rotating mechanism adds additional disturbance to the water body entering the connecting pipe 101, thereby enhancing the kinetic energy of the water flow, providing favorable conditions for enhancing the cavitation reaction, and achieving the purpose of enhancing the occurrence of cavitation. At the same time, the air intake mechanism injects inert gas into the interior of the connecting pipe 101, which can increase the bubbles in the water flow in the connecting pipe 101 and provide the gas nuclei necessary for cavitation to occur, thereby achieving the purpose of strengthening the occurrence of hydraulic cavitation.

[0024] The first cavitation mechanism is provided with multiple groups, and the multiple groups of first cavitation mechanisms are connected to the connecting pipe 101 in a circular array. The first cavitation mechanism includes a first water inlet pipe 201, and the first water inlet pipe 201 is fixedly inserted and connected to the front of the connecting pipe 101. The front of the first water inlet pipe 201 is fixedly connected to the first contraction tube 202, and the front of the first contraction tube 202 is fixedly connected to the first throat pipe 203. The water flow in the connecting pipe 101 is diverted into multiple first water inlet pipes 201, and the water flow in the first water inlet pipe 201 enters the first contraction tube 202. The aperture of the first contraction tube 202 gradually decreases, so that the flow cross-sectional area of ​​the water flow in the first contraction tube 202 is reduced, the water flow rate increases rapidly, and the pressure is reduced, so that bubbles are generated in the water flow and cavitation occurs in the first throat pipe 203.

[0025] The second cavitation mechanism is connected to the first cavitation mechanism, and the second cavitation mechanism includes a second water inlet pipe 301. The front faces of multiple first throat pipes 203 are fixedly connected to the back faces of the second water inlet pipe 301. The front face of the second water inlet pipe 301 is fixedly connected to a second contraction tube 302, and the front face of the second contraction tube 302 is fixedly connected to a second throat pipe 303. The water flow that has undergone preliminary cavitation through multiple first cavitation mechanisms converges into the second water inlet pipe 301 again, wherein the aperture of the second contraction tube 302 gradually decreases, thereby reducing the flow cross-sectional area of ​​the water flow in the second contraction tube 302, rapidly increasing the water flow rate, and reducing the pressure, so that bubbles are generated again in the water flow, and cavitation occurs in the second throat pipe 303, thereby enhancing the cavitation of the water flow.

[0026] Among them, the air intake mechanism includes multiple air intake pipes 701, and the multiple air intake pipes 701 are fixedly inserted and connected to the outer wall of the connecting pipe 101 in a circular array. The end of the outer wall of the air intake pipe 701 is fixedly sleeved with a third connecting ring 702, and the outer wall of the third connecting ring 702 is provided with multiple third connecting holes 703. The third connecting ring 702 and the third connecting hole 703 are used to facilitate the connection of the air intake pipe 701 with the external air supply equipment, so that the inert gas can be stably injected into the interior of the connecting pipe 101 through the air intake pipe 701, thereby allowing the inert gas to mix with the water in the connecting pipe 101, creating favorable conditions for cavitation of the water.

[0027] Among them, the rotating mechanism includes a rotating shaft 401, one end of the rotating shaft 401 is rotatably connected to the inner wall of the connecting pipe 101, and the other end of the rotating shaft 401 is fixedly connected to a turntable 402. The outer wall of the turntable 402 is fixedly connected to a plurality of spoiler blades 403 in a circular array. When water enters the connecting pipe 101, the water flow will impact the spoiler blades 403, so that the turntable 402 can drive the rotating shaft 401 to rotate, thereby causing the plurality of spoiler blades 403 to rotate inside the connecting pipe 101. The rotating spoiler blades 403 can increase the fluidity of the water inside the connecting pipe 101 and increase the kinetic energy of the water, thereby enhancing the subsequent cavitation of the water.

[0028] Among them, the position of the first throat pipe 203 corresponds to the position of the second contraction tube 302, so that the water flow out of the first throat pipe 203 can directly hit the inclined surface of the inner wall of the second contraction tube 302, thereby causing the water flow to collide, promoting the generation of cavitation bubbles during the second cavitation of the water body, and further enhancing the cavitation of the water body.

[0029] Among them, a first connecting ring 501 is fixedly sleeved on the end of the outer wall of the connecting pipe 101, and a plurality of first connecting holes 502 are opened on the front of the first connecting ring 501. The first connecting ring 501 and the first connecting holes 502 facilitate the connection of the connecting pipe 101 with the external pipeline, so that the water to be cavitated can stably enter the connecting pipe 101 and be cavitated through the first cavitation mechanism and the second cavitation mechanism.

[0030] Among them, a second connecting ring 601 is fixedly sleeved on the end of the outer wall of the second throat pipe 303, and a plurality of second connecting holes 602 are opened on the front of the second connecting ring 601. The second connecting ring 601 and the second connecting holes 602 facilitate the connection of the second throat pipe 303 with the external pipeline, so that the water body after cavitation is completed can be discharged stably for use.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
