[0017] The technical scheme in the embodiments of the utility model will be apparently and completely described in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0018] Please refer to Figures 1-3The utility model discloses an embodiment of a kind of microbial fermentation air inlet device, including lower U-shaped pipe 1 and upper U-shaped pipe 4, the middle section of lower U-shaped pipe 1 is welded with the input pipe 2 of downward protruding, the middle section of upper U-shaped pipe 4 is welded with the output pipe 5 of upward protruding, the input end of input pipe 2 is connected with air compressor by pipeline, the output end of output pipe 5 is connected with air cooler by pipeline, the both ends of lower U-shaped pipe 1 and the both ends of upper U-shaped pipe 4 are aligned in up-down direction, the port position of lower U-shaped pipe 1 and upper U-shaped pipe 4 alignment is all installed with deep filter 3, the upper of upper U-shaped pipe 4 vertical pipe portion is installed with the closure mechanism that penetrates to the inner wall of upper U-shaped pipe 4 vertical pipe portion, the lower of the inner wall of two vertical pipe portions of upper U-shaped pipe 4 is shaped with the docking mechanism that closure mechanism is in accord with, the two vertical pipe portions of lower U-shaped pipe 1 are installed with manual valve 6.

[0019] In the embodiment: when starting air compressor operation, air compressor is pressed into pipeline with external air and enters the inside of lower U-shaped pipe 1 by input pipe 2, and the compressed air enters deep filter 3 by one output port (because one manual valve 6 is in open state, and another manual valve 6 is in closed state) of lower U-shaped pipe 1, and deep filter 3 carries out interception to the impurity, bacteria contained in air, realizes effective filtration to air, and the filtered air enters upper U-shaped pipe 4, and enters output pipe 5 by upper U-shaped pipe 4, and then enters air cooler, realizes the cooling of compressed air, and then enters gas-liquid separator, realizes gas-liquid separation, guarantees that the air entering fermentation tank is relatively pure;

[0020] When deep filter 3 needs to be replaced after long time use, the manual valve 6 that is opened is closed, and another manual valve 6 that is closed is opened, and the compressed gas enters another deep filter 3 from another outlet of lower U-shaped pipe 1, and the above operation is repeated;

[0021] After the deep filter 3 that needs to be replaced is removed, the closure mechanism above the deep filter 3 is pushed down to the lowest position, and the closure mechanism is docked with the docking mechanism at this time, and then the deep filter 3 that needs to be replaced can be removed, after the deep filter 3 is removed, external air cannot exchange gas with the inner wall of upper U-shaped pipe 4 at this time, and after replacing new deep filter 3, the cleanliness of the inside of upper U-shaped pipe 4 can be ensured in subsequent use process;

[0022] And the design can ensure that the operation is not stopped.

[0023] Please refer to Figure 2 And Figure 3The docking mechanism includes a transition cone surface 13 integrally formed on the lower inner wall of the vertical section of the upper U-shaped tube 4. The transition cone surface 13 has a cone structure that is wider at the top and narrower at the bottom. The two docking interfaces of the vertical section of the upper U-shaped tube 4 are integrally formed with inlet ports 14 that are opposite to the narrow lower surface of the transition cone surface 13. The sealing mechanism includes a guide sleeve 7 integrally formed on the upper outer wall of the bend section of the upper U-shaped tube 4. A sliding rod 8 is inserted into the inner wall of the guide sleeve 7. A limit ring 9 is integrally formed on the outer wall of the sliding rod 8 above the guide sleeve 7. A handle 10 is fixedly installed on the top of the sliding rod 8. A plug 12 is fixedly installed on the bottom of the sliding rod 8.

[0024] In this embodiment: when the corresponding sealing mechanism needs to be closed, the operator applies downward pressure to the handle 10, and the handle 10 pushes the sliding rod 8 down along the inner wall of the guide sleeve 7 until the sliding rod 8 slides to the lowest position. At this time, the sliding rod 8 drives the plug 12 to completely block the inner wall of the inlet 14. At this time, the bottom end of the plug 12 is flush with the bottom end of the upper U-shaped tube 4. At this time, the deep filter 3 that needs to be replaced can be disassembled. After the deep filter 3 is disassembled, external air cannot enter the interior of the upper U-shaped tube, thereby preventing dust or bacteria in the external air from entering the fermenter through the pipe during subsequent operation.

[0025] Please refer to this carefully. Figure 2 The outer diameter of the plug 12 is equal to the inner diameter of the inlet 14, and a sealing ring is installed on the outer wall of the plug 12. The outer diameter of the sliding rod 8 is equal to the inner diameter of the guide sleeve 7, and a sealing ring is installed on the outer wall of the sliding rod 8.

[0026] In this embodiment: the design of the sealing ring can improve the sealing ring at the docking position, thereby further preventing air from entering the interior of the upper U-shaped tube 4;

[0027] It should be noted that when pushing the sliding rod 8 downward, or when the sliding rod 8 drives the plug 12 to move upward to reset, the bottom of the sliding rod 8 and the plug 12 need to be heated with a spray gun to achieve a sterilization effect. Since the compressed air needs to be cooled in subsequent operations, it will not affect the air temperature entering the fermenter.

[0028] Please refer to this carefully. Figure 2 The inner wall of the depth filter 3 is equipped with a porous limiting mesh 11, and the inner wall of the depth filter 3 is filled with an intercepting medium between the two limiting meshes 11.

[0029] In this embodiment, the intercepting medium is typically composed of multiple layers of filter media made of different materials, such as fiberglass, cotton, and activated carbon. It is cylindrical or block-shaped, with an outer shell encapsulating the filter media. It has inlet and outlet ports at both ends, allowing air to pass through along a specific path. The working principle relies primarily on inertial collision, interception, diffusion, and electrostatic adsorption. When air containing impurities passes through, larger dust particles and microorganisms are trapped due to inertial collisions with the filter media; smaller particles diffuse to the surface of the filter media due to Brownian motion in the airflow and are adsorbed; simultaneously, some charged particles are removed by the electrostatic attraction of the filter media.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
