Description

Technical Field

[0001] The utility model relates to the field of fermentation devices, in particular to an exhaust module device for a fermentation tank. Background Art

[0002] Fermentation refers to the process in which people use the life activities of microorganisms under aerobic or anaerobic conditions to prepare the microbial cells themselves, or direct metabolites or secondary metabolites. The fermenter is a tank-shaped device in which microorganisms form the desired products through fermentation. The exhaust module is an important component structure in the aerobic fermenter, and together with the air intake module, it maintains the stability of the air pressure in the fermenter.

[0003] As for the current fermentation tank exhaust module device, the exhaust function is often achieved by manually controlling the switch of the one-way valve. In this way, the exhaust rate cannot be adjusted according to the air pressure in the fermentation tank, which in turn affects the quality of the fermentation product and may increase the workload of the staff to a certain extent. In addition, the gas discharged from the fermentation tank often has some more irritating odors, which may have a certain negative impact on the external air.

[0004] Therefore, those skilled in the art provide a fermentation tank exhaust module device to solve the problems raised in the above background technology. Utility Model Content

[0011] Furthermore, a support frame is provided on the outer surface of the tank body near the lower end fixing sleeve, and two vertical slide grooves are provided on the inner surface of one end of the exhaust pipe near the tank body;

[0025] The utility model has the following beneficial effects:

[0026] 1. The utility model proposes a fermentation tank exhaust module device, in which a speed regulating mechanism is provided. During use, the rotating mechanism and the sliding mechanism move upward under the action of the internal and external air pressure difference, and the rotating mechanism rotates at the same time. The two mechanisms directly produce an angle difference to achieve the adjustment of the size of the vent. This not only can realize real-time automatic adjustment of the exhaust rate, ensure the stability of the air pressure in the tank, and thus ensure the quality of the fermentation product, but also can reduce the burden on the staff to a certain extent.

The air intake module continuously inputs compressed sterile gas into the tank. In order to ensure the stability of the air pressure in the tank, the exhaust gas is discharged into the atmosphere from the pipeline of the exhaust mechanism 3.

[0039] A speed regulating mechanism 4 is fixedly arranged inside the exhaust mechanism 3, and the speed regulating mechanism 4 includes a rotating mechanism 401, a sliding mechanism 402 and a threaded rod 404. The speed regulating mechanism 4 is fixedly arranged on the inner surface of the exhaust pipe 301 close to the tank body 2, and the deodorizing mechanism 5 is slidably arranged in the pipe body of the exhaust pipe 301 away from the tank body 2. The rotating mechanism 401 is sleeved on the rod body of the threaded rod 404, and the sliding mechanism 402 is sleeved on the rod body of the threaded rod 404. Support rods 403 are fixedly arranged on both sides of the rod body of the threaded rod 404 near the lower end, and the opposite ends of the two support rods 403 are fixedly connected to the inner surface of the exhaust pipe 301, and the upper ends of the opposite ends of the two support rods 403 are fixedly arranged with buffer pads 405;

[0040] The rotating mechanism 401 includes an annular rotating block 40101, two inner sliders 40102 and a plurality of fan-shaped blades 40103. An annular sliding groove 40104 is provided at the lower end of the annular rotating block 40101.

[0041] The sliding mechanism 402 includes a windshield frame 40201, two outer sliding blocks 40202 are fixedly arranged on the outer surface of the windshield frame 40201, two sliding limit blocks 40203 are fixedly arranged on the upper end of the windshield frame 40201, an annular rotating block 40101 is slidably sleeved on the position of the threaded rod 404 near the upper end, the windshield frame 40201 is slidably sleeved on the position of the threaded rod 404 near the lower end, two inner sliding blocks 40102 are respectively slidably arranged in two thread grooves of the threaded rod 404, two outer sliding blocks 40202 are respectively slidably arranged in the vertical slide groove 304, and two sliding limit blocks 40203 are both slidably arranged in the annular slide groove 40104;

[0042] The device is provided with a speed regulating mechanism 4. When the air pressure inside the tank is greater than the external air pressure, the pressure difference will push the rotating mechanism 401 and the sliding mechanism 402 to move upward synchronously. The rotating mechanism 401 rotates while sliding upward, and the sliding mechanism 402 slides vertically upward, resulting in an angle difference between the two, thereby changing the size of the vent to achieve the adjustment of the exhaust rate.

[0044] The device is provided with a deodorizing mechanism 5, in which the filter element 502 plays a major role. The superposition of multiple layers of filter elements 502 can fully purify the gas. By pressing the card block downward at the same time, the deodorizing mechanism 5 can be taken out, and the filter element 502 can be replaced regularly.

[0045] Working principle: When the exhaust module device starts to work, the internal air pressure is greater than the external air pressure, and the internal air pressure will push the rotating mechanism 401 and the sliding mechanism 402 to move upward. Under the joint action of the inner slider 40102 and the threaded rod 404, the rotating mechanism 401 rotates while moving upward, and under the action of the outer slider 40202 and the vertical slide groove 304, the sliding mechanism 402 only slides upward without rotating. In this way, the two mechanisms will produce an angle difference. The size of the angle difference determines the size of the vent area. The change in air pressure can drive the change of the vent, thereby achieving the purpose of adjusting the exhaust rate; when the gas reaches the deodorization mechanism 5, the gas will be purified under the action of the multi-layer filter element 502. After using it for a period of time, press the rotating block 303 downward, hold the handle 503 and pull the deodorization mechanism 5 outward, so that the filter element 502 can be replaced for subsequent use.

[0046] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
