Description

Technical Field

[0001] This utility model relates to the field of fermentation aeration technology, specifically a combined fermentation aeration device. Background Technology

[0002] In the fermentation industry, fermentation aeration devices play a crucial role in maintaining the aerobic respiration of microorganisms during fermentation, and their performance directly affects fermentation efficiency and product quality.

[0003] However, traditional fermentation aeration devices have some shortcomings. On the one hand, the design of the aeration heads is not reasonable enough. Many aeration heads are not effective in preventing backflow of fermenting materials, which may lead to blockage of the aeration pipe and thus affect the entire fermentation process. In addition, the maintenance and replacement of aeration heads are very inconvenient. Some traditional aeration heads are usually fixed on the air inlet pipe and cannot be disassembled. This not only requires a lot of time and manpower for maintenance and cleaning, but also increases maintenance costs. On the other hand, because the outside air contains a lot of dust and impurities, if they enter the blower directly, they will block the subsequent air outlet structure and air head structure, leading to frequent device failures and greatly shortening the service life of the device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a combined fermentation aeration device that solves the problems of inconvenient maintenance and replacement of aeration heads and blockage caused by impurities in the air.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A combined fermentation aeration device includes: a blower; an air outlet pipe fixedly connected to the inner wall of the blower, an air outlet structure fixedly connected to the outer wall of the air outlet pipe, and an air head structure slidably connected to the inner wall of the air outlet structure; the air head structure includes a connecting plate, an aeration pipe fixedly connected to the inner wall of the connecting plate, a microporous diaphragm fixedly connected to the inner wall of the aeration pipe, a baffle fixedly connected to the outer wall of the top of the aeration pipe, a clamping block slidably connected to the inner wall of the side of the connecting plate, a pull plate fixedly connected to the outer wall of the clamping block, sliding rods symmetrically fixedly connected to the inner wall of the pull plate, a limit plate fixedly connected to the outer wall of the sliding rod, and a compression spring fixedly connected to the outer wall of the limit plate.

Pulling the pull plate causes the clamping block to slide outward. Because the pull plate and the limiting plate are close to each other, the compression spring is compressed and stores force. When the pull plate is released, the clamping block is pushed back to its original position under the elastic restoring force of the compression spring. The microporous diaphragm is set above the connecting plate. The microporous diaphragm has many tiny holes. Gas is slowly discharged through these micropores, which can increase the contact time between the gas and the fermentation product and improve the contact efficiency of the gas in the fermentation product.

[0010] Preferably, the air outlet structure includes an air outlet manifold, a connecting block is fixedly connected to the outer wall of the air outlet manifold, an air outlet hole is opened on the outer wall of the air outlet manifold, clamping grooves are symmetrically opened on the outer wall of the side of the connecting block, a sealing gasket is fixedly connected to the outer wall of the top of the connecting block, and a support rod is fixedly connected to the outer wall of the air outlet manifold.

When the clamping block is inserted into the clamping groove, a tight connection between the air head structure and the air outlet structure can be achieved.

[0012] Preferably, the blower has an air intake grille on the outer wall away from the air outlet pipe; a fixed frame is fixedly connected to the outer wall of the blower, and a filter plate is slidably connected to the inner wall of the fixed frame.

[0013] Preferably, the fixed frame is set outside the air intake grille, which can filter the air, filter out some fine dust, impurities, etc., and ensure that the air entering the subsequent structure is relatively clean. The outer wall of the air outlet pipe is fixedly connected to the outer wall of the air outlet manifold, and the air is delivered to the air outlet manifold connected to it through the air outlet pipe of the blower.

[0014] (III) Beneficial Effects

[0015] This invention provides a combined fermentation aeration device. It has the following beneficial effects:

[0016] (i) The aeration head structure, through the baffle on the outer wall of the top of the aeration pipe, can not only prevent the fermented material from flowing back into the aeration pipe, but also guide the gas coming out of the microporous membrane, so that it can be more evenly diffused into the fermented material. At the same time, during installation, a simple sliding insertion operation is used to achieve a tight connection by utilizing the cooperation between the clamping block and the clamping groove and the elastic restoring force of the compression spring. When maintaining or replacing the aeration head structure, it can be removed simply by pulling the pull plate to disengage the clamping block from the clamping groove. This greatly facilitates the cleaning, maintenance or replacement of the aeration head, reduces maintenance costs and improves the maintainability of the device.

[0017] (ii) The blower, by setting a fixed frame outside the blower's air intake grille and slidingly connecting a filter plate inside the frame, can effectively filter fine dust and impurities in the outside air, preventing them from entering the blower and subsequent air outlet and air head structures, preventing damage caused by impurities clogging the air, and extending the service life of the device.

[0024] 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.

[0025] Please see Figure 1-5 This utility model provides a technical solution: a combined fermentation aeration device, comprising: a blower 1; an air outlet pipe 11 is fixedly connected to the inner wall of the blower 1, an air outlet structure 2 is fixedly connected to the outer wall of the air outlet pipe 11, and an air head structure 3 is slidably connected to the inner wall of the air outlet structure 2; the air head structure 3 includes a connecting plate 31, an aeration pipe 32 is fixedly connected to the inner wall of the connecting plate 31, a microporous diaphragm 33 is fixedly connected to the inner wall of the aeration pipe 32, a baffle 34 is fixedly connected to the outer wall of the top of the aeration pipe 32, a clamping block 35 is slidably connected to the inner wall of the side of the connecting plate 31, a pull plate 36 is fixedly connected to the outer wall of the clamping block 35, a sliding rod 37 is symmetrically fixedly connected to the inner wall of the pull plate 36, a limiting plate 38 is fixedly connected to the outer wall of the sliding rod 37, and a compression spring 39 is fixedly connected to the outer wall of the limiting plate 38.

[0026] The outer wall of the compression spring 39 on the side away from the limiting plate 38 is fixedly connected to the outer wall of the pull plate 36. The outer wall of the slide rod 37 on the side away from the limiting plate 38 is fixedly connected to the outer wall of the side of the connecting plate 31. Pulling the pull plate 36 causes the clamping block 35 to slide outward. Because the pull plate 36 and the limiting plate 38 are close to each other, the compression spring 39 is squeezed and stored. When the pull plate 36 is released, the clamping block 35 is pushed back to its original position under the elastic restoring force of the compression spring 39. The microporous diaphragm 33 is set above the connecting plate 31. The microporous diaphragm 33 has many tiny holes. Gas is slowly discharged through these micropores, which can increase the contact time between the gas and the fermentation product and improve the contact efficiency of the gas in the fermentation product.

[0027] The air outlet structure 2 includes an air outlet manifold 21, a connecting block 22 is fixedly connected to the outer wall of the air outlet manifold 21, an air outlet hole 23 is opened on the outer wall of the air outlet manifold 21, a clamping groove 24 is symmetrically opened on the outer wall of the side of the connecting block 22, a sealing gasket 25 is fixedly connected to the outer wall of the top of the connecting block 22, and a support rod 26 is fixedly connected to the outer wall of the air outlet manifold 21.

[0028] The air outlets 23 are arranged in an array along the outer wall of the air outlet manifold 21. The connecting block 22 is set outside the air outlets 23. The outer wall of the connecting block 22 is slidably connected to the inner wall of the connecting plate 31. The inner wall of the air outlets 23 is slidably connected to the outer wall of the aeration pipe 32. Gas enters the aeration pipe 32 from the air outlet manifold 21 through the air outlets 23. The outer wall of the top of the sealing gasket 25 is in contact with the inner wall of the top of the connecting plate 31. The inner wall of the clamping groove 24 is slidably connected to the outer wall of the clamping block 35. When the clamping block 35 is inserted into the clamping groove 24, a tight connection between the air head structure 3 and the air outlet structure 2 can be achieved.

[0029] An air intake grille is provided on the outer wall of the blower 1 on the side away from the air outlet pipe 11; a fixed frame 12 is fixedly connected to the outer wall of the blower 1, and a filter plate 13 is slidably connected to the inner wall of the fixed frame 12.

[0030] The fixed frame 12 is set outside the air intake grille and can filter the air, filtering out some fine dust, impurities, etc., to ensure that the air entering the subsequent structure is relatively clean. The outer wall of the air outlet pipe 11 is fixedly connected to the outer wall of the air outlet manifold 21. Air is delivered to the air outlet manifold 21 connected to it through the air outlet pipe 11 of the blower 1.

[0031] In use, air is delivered to the air outlet structure 2 through the air outlet pipe 11 of the blower 1, and then discharged through the air head structure 3 to realize the aeration operation.

[0032] Blower 1 draws in outside air through the air intake grille. In order to prevent impurities and dust from entering the blower 1 and causing blockage and damage to the subsequent air outlet structure 2 and air head structure 3, a filter plate 13 is slidably connected in the fixed frame 12 outside the air intake grille. This filter can filter out some fine dust and impurities, ensuring that the air entering the subsequent structure is relatively clean.

[0033] The filtered air is delivered to the air outlet manifold 21 connected to the blower 1 through the air outlet pipe 11. The air outlet manifold 21 is provided with multiple air outlet holes 23, which are arranged in an array along the outer wall of the air outlet manifold 21. This allows the gas to be evenly distributed in the air outlet manifold 21, preparing for the subsequent aeration process.

[0034] When gas enters the aeration pipe 32 from the outlet manifold 21 through the outlet hole 23, it will encounter the microporous membrane 33 located on the inner wall of the aeration pipe 32. The microporous membrane 33 has many tiny pores, and the gas is slowly discharged through these micropores, which can increase the contact time between the gas and the fermentation material and improve the contact efficiency of the gas in the fermentation material. The baffle 34 is located on the top outer wall of the aeration pipe 32. It can play a certain role in blocking and guiding, preventing the fermentation material from flowing back into the aeration pipe 32. At the same time, it can also guide the gas coming out of the microporous membrane 33, so that it can be more evenly diffused into the fermentation material.

[0035] The connection between the air head structure 3 and the air outlet structure 2 has a certain degree of flexibility and maintainability. When installing the air head structure 3, the aeration pipe 32 is first aligned with the inner wall of the air outlet 23 and slid in. At the same time, the connecting plate 31 is slid in along the outer wall of the connecting block 22, so that the connecting block 22 contacts the clamping block 35. As the connecting plate 31 and the connecting block 22 continue to slide, the clamping block 35 is squeezed outward along the inner wall of the side of the connecting plate 31 through its inclined surface. At the same time, the pull plate 36 is also slid outward along the slide rod 37. Because the pull plate 36 and the limiting plate 38 are close to each other, the compression spring 39 is squeezed and stored. When the connecting plate 31 is slid in place, the inner wall of the top of the connecting plate 31 contacts the outer wall of the top of the sealing gasket 25, which plays a sealing role. At the same time, the clamping block 35 is aligned with the clamping groove 24. Under the action of the elastic restoring force of the compression spring 39, the clamping block 35 is inserted into the clamping groove 24, realizing a tight connection between the air head structure 3 and the air outlet structure 2.

[0036] Conversely, when maintenance or replacement of the aeration head structure 3 is required, the pull plate 36 is pulled to disengage the clamping block 35 from the clamping groove 24, and the aeration head structure 3 can be removed from the air outlet structure 2. This modular design facilitates the disassembly and installation of the aeration head structure 3, and makes it easy to clean, repair or replace the aeration head. The support rod 26 on the air outlet manifold 21 can provide a certain support strength for the entire air outlet structure 2.
