Description

Technical Field

[0001] This utility model relates to the field of oxygen enrichment technology, and in particular to a water micro-nano bubble oxygen enrichment device. Background Technology

[0002] The core structure of water micro-nano bubble oxygen enrichment devices generally adopts a combination of "water storage tank + micro-nano bubble generator + aeration pipeline + atmospheric pressure control system". Its working logic is as follows: the micro-nano bubble generator breaks air or oxygen into micro-nano-sized fine bubbles, and then the bubbles are transported to the water storage tank through the aeration pipeline, so that the bubbles can fully contact and dissolve with the water, and finally achieve oxygen enrichment of the water. Due to its mature principle and convenient operation, this type of device is widely used in aquaculture (to ensure oxygen supply for aquatic organisms) and sewage treatment (to improve the activity of aerobic microorganisms).

[0003] Micro-nano bubble generators need to be disassembled and cleaned regularly to prevent pore blockage from affecting bubble generation efficiency. In existing devices, generators are mostly fixed with bolts, which can ensure installation stability, but there are obvious drawbacks in actual disassembly and cleaning. Disassembling and assembling a single generator requires repeatedly tightening the bolts, which is time-consuming. In addition, in some scenarios, multiple generators need to be installed at the same time, which further accumulates the disassembly and assembly time, resulting in a significant reduction in the overall efficiency of regular cleaning and making it difficult to meet the needs of efficient operation and maintenance. Utility Model Content

[0004] This utility model relates to a micro-nano bubble oxygen enrichment device for water bodies. It uses a single push cylinder as a driving source, which allows for the simultaneous control of the assembly and disassembly of two micro-nano bubble generators. Compared with traditional bolt positioning, this application can quickly achieve the assembly and disassembly of multiple micro-nano bubble generators without spending too much time on disassembly and cleaning. When the two micro-nano bubble generators are positioned, the extrusion plate will also extrude pressure on the sealing ring, so that the gap between the installation port and the micro-nano bubble generator after installation is sealed by the sealing ring, ensuring the installation is airtight and preventing leakage of the transformer water tank due to improper installation of the micro-nano bubble generator.

[0005] In a first aspect, this utility model provides a micro-nano bubble oxygen enrichment device for water, specifically comprising: a variable pressure water tank, wherein a support frame is fixedly installed at the top of the interior of the variable pressure water tank, and a dissolved oxygen detection sensor is fixedly installed at the top of the support frame; a protective cover is fixedly installed at the bottom of the dissolved oxygen detection sensor; variable pressure air guide pipes are symmetrically fixedly installed on the front and rear sides of the top of the variable pressure water tank; the variable pressure air guide pipe on the front side is an air inlet pipe, and the one on the rear side is an air outlet pipe; a solenoid valve and a pressure sensor are fixedly installed on the variable pressure air guide pipe; a water inlet pipe is fixedly installed at the bottom right side of the variable pressure water tank; a check valve is fixedly installed on the water inlet pipe; a drain pipe is fixedly installed at the bottom left side of the variable pressure water tank; and a protective cover is fixedly installed on the drain pipe. A flow regulating valve is fixedly installed; a guide rod is fixedly installed at the center of the left side of the variable pressure water tank; a push cylinder is fixedly installed at the center of the right side of the variable pressure water tank; a synchronization ring is slidably installed on the guide rod; push blocks are fixedly installed on the left and right sides of the bottom of the synchronization ring; two mounting ports are symmetrically fixedly installed on the outer circumference of the variable pressure water tank; a guide rail is fixedly installed at the inner end of the mounting port; a sealing ring is installed on the outer side of the mounting port; a micro-nano bubble generator is inserted into the mounting port; a guide block is fixedly installed on the outer circumference of the micro-nano bubble generator; a squeezing plate is fixedly installed at the rear end of the outer wall of the micro-nano bubble generator; a force-bearing block is fixedly installed on the top of the squeezing plate.

[0006] The pressure sensor and dissolved oxygen detection sensor are connected to an external control system via signal lines.

[0007] The synchronization ring is a circular ring structure; the synchronization ring is also slidably mounted on the variable pressure water tank.

[0008] The synchronizing ring is also fixedly connected to the output shaft of the push cylinder.

[0009] The guide block is slidably installed inside the guide rail.

[0010] The micro-nano bubble generator has a honeycomb-shaped airflow channel inside, with air outlets densely distributed at the front end and an external air source connected to the rear end via a flexible tube.

[0011] The top of the force-bearing block is provided with a force-bearing groove with an inclined structure.

[0012] This invention provides a micro-nano bubble oxygen enrichment device for water bodies, which has the following beneficial effects: 1. The dissolved oxygen detection sensor and pressure sensor are linked, and the pressure parameters can be adjusted in real time according to the dissolved oxygen concentration in the water to avoid "over-oxygen" or "under-oxygen", reducing energy consumption by 25%. The protective cover effectively reduces bubble impact, and the service life of the dissolved oxygen detection sensor is extended to 12-18 months, reducing replacement costs.

[0013] 2. This application uses a single push cylinder as the driving source, which can simultaneously control the disassembly and assembly of two micro-nano bubble generators. Compared with the traditional bolt positioning method, it does not require tightening the bolts one by one, and can quickly complete the disassembly and assembly of multiple generators, greatly shortening the disassembly and cleaning time and significantly improving maintenance efficiency.

[0014] 3. When the two micro-nano bubble generators are positioned, the extrusion disc driven by the push cylinder will simultaneously extrude the sealing ring, so that the sealing ring fully fills the gap between the installation port and the generator, forming a reliable seal. This design can effectively avoid the leakage problem of the transformer water tank caused by improper installation of the generator, and ensure the sealing performance of the device under transformer conditions.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] Please refer to Figures 1 to 5 Example 1: This utility model proposes a micro-nano bubble oxygen enrichment device for water bodies, comprising: a variable pressure water tank 1, a support frame fixedly installed at the top of the interior of the variable pressure water tank 1, and a dissolved oxygen detection sensor 2 fixedly installed at the top of the support frame; a protective cover 3 fixedly installed at the bottom of the dissolved oxygen detection sensor 2; variable pressure air guide pipes 4 symmetrically fixedly installed on the front and rear sides of the top of the variable pressure water tank 1; the variable pressure air guide pipe 4 on the front side is an air inlet pipe, and the one on the rear side is an exhaust pipe; a solenoid valve 5 and a pressure sensor 6 are fixedly installed on the variable pressure air guide pipe 4; a water inlet pipe 7 is fixedly installed at the bottom right side of the variable pressure water tank 1; a check valve 8 is fixedly installed on the water inlet pipe 7; a drain pipe 9 is fixedly installed at the bottom left side of the variable pressure water tank 1; a flow regulating valve 10 is fixedly installed on the drain pipe 9; the variable pressure... A guide rod 11 is fixedly installed at the center of the left side of water tank 1; a push cylinder 12 is fixedly installed at the center of the right side of transformer water tank 1; a synchronous ring 13 is slidably installed on the guide rod 11; push blocks 14 are fixedly installed on the left and right sides of the bottom of the synchronous ring 13; two mounting ports 15 are symmetrically fixedly installed on the outer circumference of transformer water tank 1; a guide rail 16 is fixedly installed at the inner end of the mounting port 15; a sealing ring 17 is installed on the outer side of the mounting port 15; a micro-nano bubble generator 18 is inserted into the inside of the mounting port 15; a guide block 19 is fixedly installed on the outer circumference of the micro-nano bubble generator 18; a compression plate 20 is fixedly installed at the rear end of the outer wall of the micro-nano bubble generator 18; a force-bearing block 21 is fixedly installed on the top of the compression plate 20.

[0020] In Example 2, based on Example 1, the pressure sensor 6 and the dissolved oxygen detection sensor 2 are connected to an external control system via signal lines; the synchronization ring 13 has a circular ring structure; the synchronization ring 13 is also slidably mounted on the variable pressure water tank 1; the synchronization ring 13 is also fixedly connected to the output shaft of the push cylinder 12.

[0021] In Example 3, based on Example 2, the guide block 19 is slidably installed inside the guide rail 16; the micro-nano bubble generator 18 has a honeycomb-shaped airflow channel inside, with densely packed air outlets at the front end and connected to an external air source via a hose at the rear end. The micro-nano bubble generator 18 is made of ceramic material, or it can be made of titanium alloy. Titanium alloy has stronger corrosion resistance, is suitable for chlorinated wastewater and high-salt seawater, and has higher hardness, making it less prone to pore deformation due to collisions, extending its service life to 1.5 times that of the original. Although the cost increases by 20%, the long-term maintenance cost is lower; the top of the force block 21 has a force groove with an inclined structure.

[0022] Working principle: During use, the micro-nano bubble generator 18 is inserted into the mounting port 15, so that the extrusion plate 20 fits against the sealing ring 17. Then, the push cylinder 12 is activated, which controls the synchronous ring 13 and the push block 14 to descend. The push block 14 pushes the inclined surface of the force groove on the force block 21 by descending, so that the force controls the micro-nano bubble generator 18 and the extrusion plate 20 to move inward. While fixing the micro-nano bubble generator 18, it can also compress and deform the sealing ring 17, improving the fit between the micro-nano bubble generator 18 and the mounting port 15. After ensuring the airtight seal between the components, open the front-side pressure-transformer air vent pipe 4 and inject the water to be treated into the pressure-transformer water tank 1 until the water level reaches two-thirds of the height of the pressure-transformer water tank 1. Then close the front-side pressure-transformer air vent pipe 4, and immediately turn on the dissolved oxygen detection sensor 2 and pressure sensor 6. Initialize the external control system parameters (target dissolved oxygen concentration 8-12 mg / L, initial pressure range 0.3-0.5 MPa). This completes the oxygen enrichment preparation stage. Open the solenoid valve 5 of the rear-side pressure-transformer air vent pipe 4 to allow the external pressure system to supply water to the pressure-transformer water tank. Pressurized gas is introduced into the internal structure of the transformer water tank 1. Pressure sensor 6 provides real-time feedback on the internal pressure of transformer water tank 1. When the pressure reaches 0.5 MPa, the solenoid valve 5 of the rear transformer air duct 4 is closed, and then the gas source valve of the micro-nano bubble generator 18 is opened. The gas is broken into 10-50 μm micro-nano bubbles through the honeycomb channel and released into the water from the front outlet. Simultaneously, dissolved oxygen detection sensor 2 monitors the dissolved oxygen concentration in the water in real time. If the dissolved oxygen is below 8 mg / L, the control system opens the solenoid valve 5 of the front transformer air duct 4 to increase the pressure. The pressure (up to 0.8 MPa) is increased to accelerate dissolved oxygen. If the dissolved oxygen is higher than 12 mg / L, the solenoid valve 5 of the rear pressure-conducting air pipe 4 is opened to release the pressure (minimum 0.2 MPa) to avoid energy waste. During the oxygen enrichment process, the protective cover 3 can prevent bubbles from directly impacting the probe of the dissolved oxygen sensor 2 to ensure stable monitoring data. After the oxygen enrichment reaches the standard (dissolved oxygen 8-12 mg / L maintained for 10 minutes), the air source of the micro-nano bubble generator 18 is turned off, and the flow regulating valve 10 is opened to discharge the oxygen-enriched water to the target scenario (such as an aquaculture pond).
