Description

Technical Field

[0001] This utility model relates to the field of cavitation technology, and in particular to a built-in Venturi tube cavitation generator for producing small molecule water. Background Technology

[0002] The Venturi tube, as a hydrodynamic cavitation generator, is widely used in various fields such as water treatment and the chemical industry. Its working principle is based on the Venturi effect: when fluid passes through the contraction section, the flow velocity increases and the pressure decreases, creating a low-pressure zone at the throat. When the fluid enters the diffusion section, the flow velocity slows down and the pressure rises again. During this process, if the pressure in the fluid drops below the saturated vapor pressure, cavitation occurs, forming cavitation bubbles. These cavitation bubbles collapse when the fluid pressure subsequently rises, releasing a significant amount of energy. This energy can be used to enhance physical and chemical processes, such as promoting the decomposition of water molecules to generate smaller water molecules.

[0003] A significant drawback of Venturi tube cavitation water generators is that insufficient inlet pressure in the Venturi tube can affect the cavitation effect. The generation of cavitation depends on the fluid reaching a sufficiently low pressure state at the throat of the Venturi tube. This requires the fluid at the inlet to have a certain initial pressure to ensure that it can be reduced below the saturated vapor pressure when passing through the contraction section. If the inlet pressure is insufficient, the pressure of the fluid at the throat may not be reduced to the level required to trigger cavitation, resulting in poor cavitation effect or even failure to generate cavitation. Utility Model Content

[0004] Specifically, the technical problem to be solved by this utility model is to provide a built-in Venturi tube cavitation generator for producing small molecule water, so as to solve the current technical problem that if the inlet pressure is insufficient, the cavitation effect is poor or even the cavitation phenomenon cannot be generated.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] An internal Venturi tube cavitation generator for producing small molecule water includes a horizontal tube. A Venturi assembly is fixed at the inlet end inside the horizontal tube. The Venturi assembly includes a horizontal flow end, a narrowing end welded to the outlet end of the horizontal flow end, a throat end welded to the end of the narrowing end away from the horizontal flow end, and a diffusion end welded to the end of the throat end away from the narrowing end.

[0007] A pressurizing component is fixed inside the advection end, and the movable end of the pressurizing component is close to the shrinking end. A semi-circular plug is fixedly connected to the movable end of the pressurizing component, and the semi-circular plug is located inside the shrinking end. The pressurizing component drives the semi-circular plug to move laterally inside the shrinking end.

[0008] As an improved technical solution, a connecting hole is provided on the peripheral surface of the throat end, and a connecting pipe is welded to the throat end at the position opposite to the connecting hole.

[0009] As an improved technical solution, the pressurization assembly includes two fixed frames inside the advection end, and a transverse chamber is fixed between the two fixed frames. A blocking plate is detachably installed at the end of the transverse chamber away from the shrinking end. A push-pull rod is slidably installed inside the blocking plate, and a circular hole for the push-pull rod to pass through is opened at the end of the transverse chamber away from the blocking plate. At the same time, a semi-circular plug is fixed at the end of the push-pull rod away from the blocking plate.

[0010] As an improved technical solution, sliding hole blocks are welded to both sides of the end of the push-pull rod away from the semi-circular plug. The sliding hole blocks are slidably connected to a positioning rod through the sliding holes on them, and the positioning rod is welded inside the transverse compartment.

[0011] As an improved technical solution, an electromagnet is fixed at the center of the end of the plug plate near the semi-circular plug, and a magnetic plate is embedded at the center of the end of the push-pull rod near the electromagnet, with the magnetic plate and the electromagnet facing each other in a magnetic repulsive state. A spring is fitted on the positioning rod on the side of the sliding block away from the electromagnet.

[0012] As an improved technical solution, a conical chamber is fixed to the end of the blocking plate away from the electromagnet, and a battery is fixed inside the conical chamber.

[0013] As an improved technical solution, a flow guide seat is fixed at one end of the semi-circular plug near the push-pull rod, and a reserved hole for the push-pull rod to pass through is opened in the middle of the flow guide seat.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are:

[0015] 1. This utility model uses a pressurizing component to laterally shift the semi-circular plug inside the narrowing end, thereby changing the flow velocity of the water as it flows through the narrowing end, thus changing the pressure of the water flow and creating a stable pressure difference. This ensures that the pressure of the fluid at the throat end can be effectively reduced to the level required to trigger cavitation, improving the cavitation effect. Furthermore, it can be adjusted in real time according to actual needs, making it more flexible.

[0016] 2. In this utility model, an inclined surface is added to the end of the semi-circular plug near the pressurizing component to guide the water flow to continuously move towards the narrowing end, avoiding the water flow from directly hitting the flat end of the semi-circular plug and turning back. Similarly, the conical chamber will also prevent the water flow from directly hitting the plug plate and turning back. Attached Figure Description

[0028] like Figures 1 to 4 As shown in the figure, this embodiment provides a built-in Venturi tube cavitation generator for generating small molecule water. This built-in Venturi tube cavitation generator for generating small molecule water includes a horizontal tube 1, and flanges are welded to both ends of the horizontal tube 1. A Venturi assembly 2 is fixed at the inlet end inside the horizontal tube 1. The Venturi assembly 2 includes a horizontal flow end 21, a narrowing end 22 is welded to the outlet end of the horizontal flow end 21, a throat end 23 is welded to the end of the narrowing end 22 away from the horizontal flow end 21, and a diffuser end 24 is welded to the end of the throat end 23 away from the narrowing end 22.

[0029] The interior of the advection end 21 is fixed with a pressurizing component 3, and the movable end of the pressurizing component 3 is close to the side of the shrinking end 22. The movable end of the pressurizing component 3 is fixedly connected with a semi-circular plug 4, and the semi-circular plug 4 is located inside the shrinking end 22. The pressurizing component 3 drives the semi-circular plug 4 to move laterally inside the shrinking end 22. The center lines of the semi-circular plug 4, the advection end 21 and the shrinking end 22 coincide.

[0030] The pressurizing component 3 moves the semi-circular plug 4 laterally inside the narrowing end 22 to change the flow velocity of the water as it flows through the narrowing end 22, thereby changing the pressure of the water flow and making it have a stable pressure difference. This ensures that the pressure of the fluid at the throat end 23 can be effectively reduced to the level required to trigger cavitation, thus improving the cavitation effect. Furthermore, it can be adjusted in real time according to actual needs, making it more flexible.

[0031] like Figures 1 to 2 As shown in the figure, in this embodiment, a connecting hole is provided on the peripheral surface of the throat end 23, and a connecting pipe 25 is welded to the position of the throat end 23 opposite to the connecting hole, and the connecting pipe 25 passes through the horizontal pipe 1 and is located outside the horizontal pipe 1.

[0032] like Figures 1 to 4As shown in the figure, in this embodiment, the pressurizing component 3 includes two fixed brackets 31 fixed inside the advection end 21. A horizontal chamber 33 is fixed between the two fixed brackets 31. A blocking plate 39 is detachably installed at the end of the horizontal chamber 33 away from the narrowing end 22. A push-pull rod 36 is slidably installed inside the blocking plate 39. A circular hole for the push-pull rod 36 to pass through is opened at the end of the horizontal chamber 33 away from the blocking plate 39. At the same time, a semi-circular plug 4 is fixed at the end of the push-pull rod 36 away from the blocking plate 39.

[0033] like Figure 4 As shown, in this embodiment, sliding hole blocks 32 are welded to both sides of the end of the push-pull rod 36 away from the semi-circular plug 4. The sliding hole blocks 32 are slidably connected to the positioning rod 35 through the sliding holes on them, and the positioning rod 35 is welded inside the transverse compartment 33.

[0034] like Figure 4 As shown, in this embodiment, an electromagnet 37 is fixed at the center of the end of the blocking plate 39 near the semi-circular plug 4, and a magnetic plate is embedded at the center of the end of the push-pull rod 36 near the electromagnet 37. The magnetic plate and the opposite surface of the electromagnet 37 are in a state of magnetic repulsion. A spring 34 is sleeved on the positioning rod 35 on the side of the sliding block 32 away from the electromagnet 37.

[0035] like Figure 4 As shown, in this embodiment, a conical chamber 38 is fixed to the end of the blocking plate 39 away from the electromagnet 37, and a battery and a controller are fixed inside the conical chamber 38.

[0036] like Figure 4 As shown, in this embodiment, a flow guide seat 41 is fixed at one end of the semi-circular plug 4 near the push-pull rod 36, and a reserved hole for the push-pull rod 36 to pass through is provided in the middle of the flow guide seat 41. The flow guide seat 41 is installed at one end of the semi-circular plug 4 near the pressurizing component 3. The inclined surface of the flow guide seat 41 guides the water flow to move continuously towards the narrow end 22, avoiding the water flow from directly hitting the flat end of the semi-circular plug 4 and turning back. Similarly, the setting of the conical chamber 38 will also prevent the water flow from directly hitting the plug plate 39 and turning back.

[0037] When in use, the water flows into the interior of the horizontal pipe 1 from the inlet end of the horizontal pipe 1, and then enters the interior of the horizontal end 21, and then enters the interior of the throat end 23 through the narrowing end 22. After cavitation inside the throat end 23, it is discharged through the diffuser end 24.

[0038] In the initial state, under the elastic action of the spring 34, the push rod 36 will be pushed towards the electromagnet 37, so that the semi-circular plug 4 is close to the inlet end of the narrowing end 22. At this time, even if the semi-circular plug 4 blocks the narrowing end 22, the flow velocity through the narrowing end 22 is the smallest, that is, the pressure through the horizontal end 21 and the narrowing end 22 is the largest.

[0039] When electromagnet 37 is in the open state, electromagnet 37 and the magnetic plate on push rod 36 repel each other, pushing push rod 36 towards semi-circular plug 4. This pushes semi-circular plug 4 towards the outlet end of narrowing end 22, blocking the outlet end of narrowing end 22. The outlet end of narrowing end 22 becomes smaller again, and its flow velocity will further increase and the pressure will decrease. Therefore, depending on the actual situation, the pressurizing component 3 can be used to laterally move semi-circular plug 4 inside narrowing end 22 to change the flow velocity of water when it flows through narrowing end 22, thereby changing the water pressure.

[0040] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
