Description

Technical Field

[0001] This utility model relates to the field of cellar oxygenation technology, and in particular to a microporous oxygenation and gas diversion device for cellars. Background Technology

[0002] In the food fermentation and brewing industries, fermentation pits serve as the core fermentation containers. The metabolic activities of the microorganisms inside directly determine the quality and efficiency of the fermentation products. Oxygen supply is one of the key factors affecting microbial metabolism. In order to meet the continuous oxygen demand of the fermentation materials in the fermentation pits, and at the same time ensure that the gas is evenly distributed in the materials to avoid local hypoxia or over-aeration, microporous oxygen supply and gas guiding devices for fermentation pits have emerged.

[0003] Currently, the core mechanical structure of existing fermentation pit oxygenation and gas diversion devices typically includes an air compressor, a main gas pipeline, branch gas pipelines, and aeration components. The air compressor, as the gas source, pressurizes external air to a certain pressure through mechanical compression to meet the needs of long-distance gas transportation and penetration into fermentation materials. The main gas pipeline uses rigid pipe material, with one end connected to the output end of the air compressor and the other end extending into the fermentation pit, responsible for delivering compressed air into the pit. The aeration components are mostly tubular or disc-shaped structures with small holes, fixed at the end of the branch gas pipeline, used to convert compressed air into small bubbles and release them into the fermentation materials.

[0004] However, existing fermentation pit oxygenation and gas diversion devices generally suffer from the problem of dust and impurities easily entering the aeration components during actual operation, causing pore blockage. Because the existing devices' air supply equipment directly draws in dust, particles, and other impurities from the outside air during the intake process, and the existing gas delivery pipeline system lacks effective pre-filtration and intermediate interception structures, these dust and impurities enter the main gas delivery pipeline and branch gas delivery pipelines along with the compressed air, eventually reaching the aeration components. The particle diameter of these dust and impurities is often larger than or close to the pore size, making them easily stuck inside the pores and difficult to expel through gas flow, leading to a decline in the quality of fermentation products and increased batch-to-batch variations. Therefore, a microporous oxygenation and gas diversion device for fermentation pits is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a microporous oxygen supply and gas guiding device for cellars, which aims to improve the problem in the prior art where dust particles are easily stuck in the pores, causing microporous blockage.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A microporous oxygen supply and gas diversion device for a cellar includes a cellar body, a cover plate on the top of the cellar body, a blower fixedly connected to the top of the cover plate, a diversion air pipe fixedly connected to the output end of the blower, a filter assembly inside the diversion air pipe, a microporous air pipe at the bottom of the diversion air pipe, and a quick-release assembly on the inner wall of the microporous air pipe.

[0008] The filter assembly includes a filter screen, the outer wall of which is disposed inside the air guide tube. A guide block is fixedly connected to the top of the filter screen. A slot is formed inside the guide block. A mounting bracket is slidably connected to the outer wall of the guide block. The outer wall of the mounting bracket is fixedly connected to the inner wall of the air guide tube. A retaining ball is slidably connected to the inner wall of the mounting bracket. The outer wall of the retaining ball is slidably connected to the inner wall of the slot. A limit block is fixedly connected to the outer wall of the retaining ball. A reset assembly is disposed inside the mounting bracket.

[0009] As a further description of the above technical solution:

[0010] The reset assembly includes a spring, the outer wall of which is disposed inside the mounting bracket. One end of the spring is fixedly connected to the inner wall of the mounting bracket, and the other end of the spring is fixedly connected to the outer wall of the limiting block.

[0011] As a further description of the above technical solution:

[0012] The quick-release assembly includes a connecting tube, the outer wall of which is fixedly connected to the inner wall of the microporous air tube.

[0013] As a further description of the above technical solution:

[0014] A sealing ring is fixedly connected to the top of the microporous air tube, and the outer wall of the connecting tube is slidably connected to the inner wall of the guide air tube.

[0015] As a further description of the above technical solution:

[0016] The guide tube has a fixing hole inside, and the microporous tube has a bracket fixedly connected to its outer wall.

[0017] As a further description of the above technical solution:

[0018] The bracket has a slidable pin on its inner wall, and the outer wall of the pin is slidably connected to the inner wall of the fixing hole.

[0019] As a further description of the above technical solution:

[0020] One end of the locking post is fixedly connected to a pull rod, and the outer wall of the pull rod is slidably connected to the inner wall of the bracket.

[0021] As a further description of the above technical solution:

[0022] A second spring is installed inside the bracket. One end of the second spring is fixedly connected to the inner wall of the bracket, and the other end of the second spring is fixedly connected to the outer wall of the locking post.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the filter screen is installed inside the air guide tube by moving the ball into the slot. The filter screen then intercepts dust and impurities, thus preventing dust and impurities from entering the microporous air tube. Because the pores of the microporous air tube are extremely small, dust particles are easily trapped in the pores, causing microporous blockage. In severe cases, this can lead to the failure of the microporous air tube. This allows the device to operate continuously and stably, ensuring the oxygenation and gas flow effect in the fermentation pit, and improving the quality and efficiency of fermentation.

[0025] 2. In this utility model, the microporous air tube is quickly disassembled by sliding the locking pin on the inner wall of the fixing hole and then sliding the connecting tube on the inner wall of the guide tube. This avoids the need for tools to be used during the installation and disassembly of traditional microporous air tubes, which are usually connected by clamps, screws and seals. This process is cumbersome, time-consuming and labor-intensive. Therefore, the microporous air tube can be disassembled and installed without cumbersome tools and complicated operation steps, thus improving the overall work efficiency.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-3 This utility model provides an embodiment of a microporous oxygenation and gas diversion device for a fermentation pit, comprising a pit body 1 with a top-opening structure for containing fermentation materials, providing a closed and stable space for microbial fermentation, and ensuring that the fermentation process is not disturbed by the external environment. A cover plate 2 is provided on the top of the pit body 1, covering the top opening to isolate external dust and impurities and maintain stable temperature and humidity within the pit. A fan 3 is fixedly connected to the top of the cover plate 2, pressurizing outside air and delivering it to a gas diversion pipe 4 to provide oxygenation for the entire oxygenation system. A continuous airflow is provided to meet the oxygen requirements of microorganisms in the fermentation pit. A guide pipe 4 is fixedly connected to the output end of the blower 3. The guide pipe 4 is used to guide the compressed air delivered by the blower 3 to the microporous pipe 5 to achieve the effect of directional gas delivery. A filter component is installed inside the guide pipe 4. A microporous pipe 5 is installed at the bottom of the guide pipe 4. The wall of the microporous pipe 5 is evenly provided with several tiny pores to disperse the compressed air delivered by the guide pipe 4 into the fermentation material in the main body of the fermentation pit 1, thereby increasing the contact area between oxygen and material and improving the uniformity of oxygen supply. A quick-release component is installed on the inner wall of the microporous pipe 5.

[0035] The filter assembly includes a filter screen 6, which traps dust and impurities in the air, preventing them from entering the microporous air tube 5 and clogging its pores. This ensures that all air flowing through the guide air tube 4 is filtered by the filter screen 6, guaranteeing the ventilation efficiency of the microporous air tube 5. The outer wall of the filter screen 6 is located inside the guide air tube 4. A guide block 7 is fixedly connected to the top of the filter screen 6, providing positioning guidance for its installation and ensuring that the filter screen 6 can accurately snap into the mounting bracket 9, achieving a quick and precise installation. A slot 8 is provided inside the guide block 7, which engages with a locking ball 10 to fix the filter screen 6 and prevent it from shifting under airflow impact. The mounting bracket 9 is slidably connected to the outer wall of the guide block 7, and its outer wall is fixedly connected to the inner wall of the guide air tube 4. A locking ball 10 is slidably connected to the inner wall of the mounting bracket 9. Ball 10 is inserted into slot 8 to limit the guide block 7. This, combined with the reset component, enables quick fixing and disassembly of filter 6, achieving convenient operation. The outer wall of ball 10 is slidably connected to the inner wall of slot 8, and a limiting block 11 is fixedly connected to the outer wall of ball 10. The limiting block 11 restricts the sliding stroke of ball 10, preventing it from detaching from mounting frame 9 and ensuring the stability of the fit between ball 10 and slot 8. A reset component is installed inside mounting frame 9, including spring 12. The outer wall of spring 12 is located inside mounting frame 9, with one end fixedly connected to the inner wall of mounting frame 9 and the other end fixedly connected to the outer wall of limiting block 11. Spring 12 transmits its elastic force to ball 10 through limiting block 11, pushing ball 10 into slot 8, achieving automatic locking of filter 6.

[0036] Reference Figure 4 and Figure 5The quick-release assembly includes a connecting tube 14, which is a hollow tubular structure used to insert into the guide air tube 4 to achieve initial docking between the microporous air tube 5 and the guide air tube 4, providing a foundation for subsequent fixation and achieving the effect of positioning connection. The outer wall of the connecting tube 14 is fixedly connected to the inner wall of the microporous air tube 5. A sealing ring 13 is fixedly connected to the top of the microporous air tube 5, which fills the gap between the connection between the microporous air tube 5 and the guide air tube 4, achieving the effect of preventing airflow leakage and improving airtightness. The outer wall of the connecting tube 14 is slidably connected to the inner wall of the guide air tube 4. A fixing hole 15 is opened inside the guide air tube 4, which cooperates with the locking post 17 to fix the microporous air tube 5 and the guide air tube 4, achieving the effect of preventing the connection from loosening. A bracket 16 is fixedly connected to the outer wall of the microporous air tube 5. The bracket 16 is a block-shaped support structure used to support the locking post 17, the pull rod 18, and the spring 19, providing support for the quick-release assembly. The bracket 16 provides a stable support base. A locking post 17 is slidably connected to the inner wall of the bracket 16. The locking post 17 is a columnar structure used to insert into the fixing hole 15 to lock the microporous air tube 5 and the guide air tube 4. It works with spring 19 to automatically lock, achieving a quick fixation effect. The outer wall of the locking post 17 is slidably connected to the inner wall of the fixing hole 15. One end of the locking post 17 is fixedly connected to a pull rod 18, which is pulled by the operator to disengage the locking post 17 from the fixing hole 15, achieving a convenient unlocking effect. The outer wall of the pull rod 18 is slidably connected to the inner wall of the bracket 16. Spring 19 is installed inside the bracket 16. One end of spring 19 is fixedly connected to the inner wall of the bracket 16, and the other end is fixedly connected to the outer wall of the locking post 17. Spring 19 provides continuous elastic force to the locking post 17, pushing it into the fixing hole 15 to automatically lock the microporous air tube 5 and the guide air tube 4.

[0037] Working principle: First, the guide block 7 is inserted into the mounting bracket 9. Then, the guide block 7 squeezes the ball 10. When the ball 10 is squeezed, it slides on the inner wall of the mounting bracket 9. Then, the sliding of the ball 10 drives the limiting block 11 to move. Then, the movement of the limiting block 11 compresses the spring 12. After the guide block 7 is installed in place, the spring 12 rebounds and drives the limiting block 11 to reset. Then, the reset of the limiting block 11 drives the ball 10 to move into the slot 8, thus completing the installation of the filter screen 6. This prevents dust from entering the microporous air tube 5 through the guide air tube 4. Because the pores of the microporous air tube 5 are extremely small, dust particles are easily stuck in the pores, causing microporous blockage, which can lead to failure of the microporous air tube in severe cases.

[0038] When disassembling the microporous endotracheal tube 5, first pull the lever 18. Pulling the lever 18 causes the locking pin 17 to slide on the inner wall of the bracket 16. Then, the sliding of the locking pin 17 compresses the second spring 19. When the locking pin 17 moves out of the fixing hole 15, the disassembly of the microporous endotracheal tube 5 is completed. When installing the microporous endotracheal tube 5, first slide the connecting tube 14 to the inner wall of the guide tube 4. When the sealing ring 13 contacts the bottom of the guide tube 4, release the lever 18. Then, the rebound of the second spring 19 causes the locking pin 17 to reset. Then, the installation of the microporous endotracheal tube 5 is completed when the locking pin 17 moves into the fixing hole 15. This avoids the problem that traditional microporous endotracheal tubes 5 are usually connected by clamps, screws, and seals. The installation and disassembly require tools, which is cumbersome and time-consuming.
