Description

Technical Field

[0001] This utility model belongs to the technical field of bubble generators, specifically relating to a bubble generator with hydrogen peroxide dosing function. Background Technology

[0002] A bubble generator is a device that dissolves gas in a liquid under high pressure to form a supersaturated solution. According to the Yang-Laplace equation, the internal pressure of the bubble increases sharply as the radius decreases, thus accelerating the dissolution of the gas. When the bubble bursts, it can release hydroxyl radicals, which have strong oxidizing properties and can degrade pollutants.

[0003] Existing bubble generators degrade pollutants by releasing nano-sized bubbles to impact and oxidize them in wastewater. This degradation process takes a long time, resulting in low pollutant degradation efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a bubble generator with a simple structure and reasonable design that incorporates hydrogen peroxide dosing function in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A bubble generator with hydrogen peroxide dosing function includes a housing, a bubble generating device inside the housing, a hydrogen peroxide storage tank on one side of the housing, pipes fixedly connected to both ends of the hydrogen peroxide storage tank, a connecting structure installed on the free ends of the two pipes, a piston slidably connected inside the hydrogen peroxide storage tank, the periphery of the piston fitting against the inner wall of the hydrogen peroxide storage tank, hydrogen peroxide contained in the hydrogen peroxide storage tank above the piston, a first external threaded pipe and a second external threaded pipe fixedly connected to the outer wall of one side of the housing and communicating with the inside of the housing, and the free ends of the two pipes connected to the first external threaded pipe and the second external threaded pipe respectively through the connecting structure.

[0007] As a further optimization of this utility model, a water inlet pipe connector for connecting to an external water inlet pipe is fixedly connected to the top of the housing, and a drain pipe connector for connecting to an external drainage pipe is fixedly connected to the bottom of the housing. Both the water inlet pipe connector and the drain pipe connector are provided with external threads.

[0008] As a further optimization of this utility model, multiple sets of bubble generating devices are provided, with the first external threaded tube and the second external threaded tube both located between two adjacent sets of bubble generating devices.

[0009] As a further optimization of this utility model, the bubble generating device includes a partition plate disposed inside the housing. The periphery of the partition plate is fixed to the inner wall of the housing by a sealing ring. A rotating plate is disposed below the partition plate. The partition plate and the rotating plate are rotatably connected by a connecting shaft. Both the partition plate and the rotating plate are provided with through holes.

[0010] As a further optimization of this utility model, the diameter of the rotating plate is smaller than the inner diameter of the shell, and multiple blades with a spiral structure are distributed in a ring on the upper surface of the rotating plate.

[0011] As a further optimization of this utility model, the pipe is made of a flexible material, and the connection structure includes a connector rotatably connected to the free end of the pipe, and the inner wall of the connector is provided with an internal thread.

[0012] As a further optimization of this utility model, a one-way valve is installed on the pipe connected to the first external threaded pipe via the connector, and a flow valve is installed on the pipe connected to the second external threaded pipe via the connector.

[0013] As a further optimization of this utility model, a feed pipe is fixedly connected to the side wall of the hydrogen peroxide storage tank near the one-way valve. The feed pipe is connected to the inside of the hydrogen peroxide storage tank, and a sealing cap is installed on the free end of the feed pipe.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. When the water flow is blocked by the baffle below the second external threaded pipe while moving inside the shell, it will enter the bottom of the hydrogen peroxide storage tank through the pipe connected to the second external threaded pipe due to the water pressure. The water pressure will then push the piston upward, transporting the stored hydrogen peroxide to the inner cavity of the shell along the pipe and the first external threaded pipe. Since hydrogen peroxide has strong oxidizing properties, it can effectively kill bacteria, viruses and other microorganisms in the water to improve water quality and greatly improve the purification efficiency of sewage.

[0016] 2. After hydrogen peroxide is added into the shell, it moves towards the drain pipe joint along with the water flow. During the movement, it is dispersed by multiple sets of bubble generating devices, which allows the hydrogen peroxide to be fully mixed after addition. Moreover, the hydrogen peroxide can react with the bubbles generated by the bubble generating devices, causing the bubbles to burst and increasing the decontamination performance of the bubbles. This helps to better suspend and remove small particulate matter in the water, making the water clearer. Attached Figure Description

[0022] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Example

[0024] like Figure 1 - Figure 4 As shown, a bubble generator with hydrogen peroxide dosing function includes a housing 1. The top of the housing 1 is fixedly connected to a water inlet pipe connector 2 for connecting to an external water inlet pipe, and the bottom of the housing 1 is fixedly connected to a drain pipe connector 3 for connecting to an external drainage pipe. Both the water inlet pipe connector 2 and the drain pipe connector 3 are provided with external threads, so that the external water inlet pipe and the drainage pipe can be threadedly connected to the water inlet pipe connector 2 and the drain pipe connector 3 respectively through the external threads. The threaded connection method not only provides a stable connection and good sealing performance, but also facilitates installation and disassembly.

[0025] A bubble generating device is provided inside the housing 1. The bubble generating device includes a partition 4 disposed inside the housing 1. The periphery of the partition 4 is fixed to the inner wall of the housing 1 by a sealing ring. A rotating plate 5 is disposed below the partition 4. The partition 4 and the rotating plate 5 are rotatably connected by a connecting shaft 6. Both the partition 4 and the rotating plate 5 are provided with through holes 7. When water flows into the housing 1 through the water inlet pipe joint 2, it can move down through the through holes 7 on the partition 4 and the rotating plate 5, and finally be discharged from the housing 1 through the drain pipe joint 3.

[0026] The diameter of the rotating plate 5 is smaller than the inner diameter of the shell 1. Multiple spiral blades are distributed in a ring on the upper surface of the rotating plate 5. Since the rotating plate 5 is rotatably connected to the partition plate 4 through the connecting shaft 6, when the water flows through the through hole 7 on the partition plate 4, it will impact the spiral blades on the upper surface of the rotating plate 5, drive the rotating plate 5 to rotate, tear the water into fine droplets, and at the moment of sudden pressure drop, the gas dissolved in the water quickly forms micro-nano bubbles.

[0027] A hydrogen peroxide storage tank 10 is provided on one side of the shell 1. Both ends of the hydrogen peroxide storage tank 10 are fixedly connected to pipes 11. The pipes 11 are made of flexible material. A connection structure is installed on the free ends of the two pipes 11. The connection structure includes a connector 12 that is rotatably connected to the free ends of the pipes 11. An internal thread is provided on the inner wall of the connector 12.

[0028] A piston 15 is slidably connected inside the hydrogen peroxide storage tank 10. The periphery of the piston 15 is in contact with the inner wall of the hydrogen peroxide storage tank 10. The hydrogen peroxide storage tank 10 above the piston 15 contains hydrogen peroxide. A first external threaded pipe 8 and a second external threaded pipe 9, which communicate with the inside of the shell 1, are fixedly connected to the outer wall of one side of the shell 1. The free ends of the two pipes 11 are connected to the first external threaded pipe 8 and the second external threaded pipe 9 respectively through connectors 12. When the bottom of the piston 15 is pressed and slides upward along the inner wall of the hydrogen peroxide storage tank 10, it will squeeze the hydrogen peroxide stored above it into the first external threaded pipe 8 along the pipe 11, and finally flow into the inner cavity of the shell 1, realizing the automatic addition of hydrogen peroxide.

[0029] The bubble generating device is set in multiple sets, which can greatly improve the dispersion of bubbles, making the bubbles generated by the device smaller in diameter and more numerous, thus greatly improving the efficiency of pollutant degradation by the bubbles. The first external threaded pipe 8 and the second external threaded pipe 9 are both set between two adjacent sets of bubble generating devices, which can minimize the obstruction of hydrogen peroxide entering the shell 1 along the pipe 11.

[0030] A one-way valve 13 is installed on the pipe 11 connected to the first external threaded pipe 8 via connector 12, and a flow valve 14 is installed on the pipe 11 connected to the second external threaded pipe 9 via connector 12. The one-way valve 13 is set to block the water flow and gas flow inside the housing 1. The pipe 11 installed at the top of the hydrogen peroxide storage tank 10 enters the hydrogen peroxide storage tank 10. The flow valve 14 is set to adjust the amount of hydrogen peroxide added.

[0031] A replenishment pipe 16 is fixedly connected to the side wall of the hydrogen peroxide storage tank 10 near the one-way valve 13. The replenishment pipe 16 communicates with the inside of the hydrogen peroxide storage tank 10. A sealing cap 17 is installed on the free end of the replenishment pipe 16. When the hydrogen peroxide in the hydrogen peroxide storage tank 10 is used up, the user can open the sealing cap 17 and replenish the hydrogen peroxide in the hydrogen peroxide storage tank 10 through the replenishment pipe 16, so that the hydrogen peroxide storage tank 10 can be recycled.

[0032] It should be noted that in this type of bubble generator with hydrogen peroxide dosing function, when water flows into the housing 1 through the inlet pipe joint 2, the water can flow down through the through hole 7 on the baffle 4 and impact the blades on the upper surface of the rotating plate 5 below the baffle 4, causing the rotating plate 5 to rotate and tear the water into fine droplets. At the moment of sudden pressure drop, the gas dissolved in the water rapidly forms micro-nano bubbles. When the water flows to the baffle 4 below the second external threaded pipe 9, the pressure above the baffle 4 increases due to the blocking effect of the baffle 4. At this time, part of the water flow will be affected by the water pressure and pass through the second... The pipe 11 connected to the external threaded pipe 9 enters the bottom of the hydrogen peroxide storage tank 10, and the water pressure pushes the piston 15 upward. During the upward movement of the piston 15, it squeezes the hydrogen peroxide stored above it into the first external threaded pipe 8 along the pipe 11, and finally delivers it into the inner cavity of the shell 1, realizing the automatic addition of hydrogen peroxide. Since hydrogen peroxide has strong oxidizing properties, it can not only effectively kill bacteria, viruses and other microorganisms in the water and improve water quality, but also react with bubbles, causing the bubbles to burst, increasing the decontamination performance of the bubbles, helping to better suspend and remove small particulate matter in the water, making the water clearer.

[0033] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
