Description

Technical Field

[0001] This utility model relates to the field of multi-unit fermentation tank technology, and in particular to a gas path isolation component for multi-unit fermentation tanks. Background Technology

[0002] A multi-unit fermenter is a device used for microbial fermentation processes. It consists of multiple independent fermenters that can carry out different fermentation processes simultaneously or independently. This system is designed to improve fermentation efficiency, increase output, optimize production processes, and reduce costs.

[0003] The multi-unit fermenter gas supply system connects several fermenters, allowing a single gas supply device to supply gas to each fermenter, thus conveniently supplying the special gases required for the fermentation process in each fermenter.

[0004] The existing gas supply system for multi-unit fermenters mainly connects the gas inlet of each fermenter directly to the gas supply device through an external pipe, thereby supplying gas to each fermenter. However, this gas supply system results in too many gas lines and an overly complex pipeline structure, making it impossible to supply gas through a single main gas pipe, which is quite inconvenient to use. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the problems existing in the prior art, this utility model provides a gas path isolation component for multi-unit fermenters.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model is implemented through the following technical solution: a gas path isolation component for a multi-unit fermenter, comprising several main gas pipes, a transfer box fixedly connected between adjacent main gas pipes, a gas distribution pipe fixedly connected to both sides of the transfer box, two valve assemblies arranged inside the transfer box, and a limit assembly arranged on the upper surface of the transfer box;

[0009] The valve assembly includes a fixed plate fixedly connected inside a transfer box. Two rotating plates are hinged inside the transfer box. A protrusion is fixedly connected to the upper surface of the rotating plate. A movable rod that cooperates with the protrusion is slidably arranged on the upper surface of the transfer box.

[0010] The limiting assembly includes a fixed crossbar that is fixedly installed on the upper surface of the transfer box. Two threaded shafts are interposed inside the fixed crossbar, and rotating blocks are meshed with the outer surfaces of the two threaded shafts.

[0011] In a preferred embodiment of the gas path isolation assembly for a multi-unit fermenter described in this utility model, an electric push rod is fixedly connected to the upper surface of the transfer box, and the output end of the electric push rod is fixedly connected to the outer surface of the moving rod.

[0012] As a preferred embodiment of the gas path isolation component for a multi-unit fermenter described in this utility model, the upper surface of the transfer box is provided with two limiting grooves, the inner wall of the limiting groove is provided with an arc-shaped groove that cooperates with the protrusion, the lower surface of the moving rod is provided with a rectangular groove, and the top of the protrusion passes through the inside of the arc-shaped groove and is inserted into the rectangular groove on the lower surface of the moving rod.

[0013] As a preferred embodiment of the gas path isolation component for a multi-unit fermenter described in this utility model, two sealing plates are fixedly connected to both sides of the moving rod. The sealing plates abut against the inner wall of the limiting groove on the upper surface of the transfer box. Soft sealing strips for sealing are provided on the lower surface of the sealing plates and on the side of the rotating plate near the fixed plate.

[0014] In a preferred embodiment of the gas path isolation assembly for a multi-unit fermenter described in this utility model, the two threaded shafts are respectively fixedly connected to the outer surfaces of the moving rods on both sides, and the two rotating blocks are respectively disposed on both sides of the fixed crossbar.

[0015] As a preferred embodiment of the gas path isolation assembly for a multi-unit fermenter described in this utility model, the fixed crossbar has a through hole with a diameter larger than that of the threaded shaft. When the output ends of the two electric push rods extend to their maximum distance, the end of the threaded shaft near the rotating block can abut against the outer surface of the adjacent moving rod.

[0016] (III) Beneficial Effects

[0017] This invention provides a gas path isolation component for multi-unit fermenters. It has the following beneficial effects:

[0018] 1. Gas is supplied through the main gas pipe, and the gas inlet of each individual fermenter is controlled by the valve assembly of the corresponding gas distribution pipe. The moving rod is controlled by an electric push rod, and the rectangular groove on the lower surface of the moving rod cooperates with the protrusion to drive the rotating plate to rotate. This allows the gas inside the main gas pipe to enter the transfer box near the gas distribution pipe, and then enter the designated fermenter through the gas distribution pipe. The gas pipeline is simple and clear, making it easy to control the opening and closing of the gas inlet of individual fermenters.

[0019] 2. By rotating the rotating block, the rotating block moves on the outer surface of the threaded shaft. When the electric push rod drives the moving rod to move, the rotating block on the outer surface of the threaded shaft abuts against the outer surface of the fixed crossbar. At this time, the moving rod moves to its maximum distance, thereby limiting the maximum opening and closing degree that the rotating plate can rotate, and avoiding excessive rotation that would cause the gas flow rate to be too fast and affect the control of the gas supply.

Detailed Implementation

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] Example 1

[0030] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5This is the first embodiment of the present invention. This embodiment provides a gas path isolation component for a multi-unit fermenter, including several main gas pipes 1, a transfer box 3 fixedly connected between adjacent main gas pipes 1, a gas distribution pipe 2 fixedly connected to both sides of the transfer box 3, two valve components 4 provided inside the transfer box 3, and a limit component 5 provided on the upper surface of the transfer box 3.

[0031] The valve assembly 4 includes a fixed plate 404 fixedly connected inside the transfer box 3. Two rotating plates 403 are hinged inside the transfer box 3. A protrusion 406 is fixedly connected to the upper surface of the rotating plate 403. A moving rod 402 that cooperates with the protrusion 406 is slidably arranged on the upper surface of the transfer box 3.

[0032] Specifically, an electric push rod 401 is fixedly connected to the upper surface of the transfer box 3, and the output end of the electric push rod 401 is fixedly connected to the outer surface of the moving rod 402.

[0033] Specifically, the upper surface of the transfer box 3 is provided with two limiting grooves. The inner wall of the limiting groove is provided with an arc-shaped groove that cooperates with the protrusion 406. The lower surface of the moving rod 402 is provided with a rectangular groove. The top of the protrusion 406 passes through the inside of the arc-shaped groove and is inserted into the rectangular groove on the lower surface of the moving rod 402. The movement of the protrusion 406 is limited by the arc-shaped groove inside the limiting groove. Thus, when the moving rod 402 moves, the rotation plate 403 can be driven to rotate by the protrusion 406 through the cooperation of the rectangular groove and the arc-shaped groove on the lower surface of the moving rod 402.

[0034] Specifically, two sealing plates 405 are fixedly connected to both sides of the moving rod 402. The sealing plates 405 abut against the inner wall of the limiting groove on the upper surface of the transfer box 3. The lower surface of the sealing plates 405 and the side of the rotating plate 403 near the fixed plate 404 are provided with soft sealing strips for sealing. By setting the sealing plates 405 and the soft sealing strips, the opening of the arc groove is sealed to prevent air leakage.

[0035] Furthermore, by connecting the gas supply device to the main gas pipe 1, gas can be delivered to the entire gas system through the gap between the two fixed plates 404 inside the transfer box 3. Then, depending on the specific situation of different fermenters, it is selected whether to open the valve assembly 4 to supply gas. The fermenter that needs gas supply controls the corresponding valve assembly 4. The electric push rod 401 controls the movement of the moving rod 402, so that the rectangular groove on the lower surface of the moving rod 402 cooperates with the protrusion 406, so that the protrusion 406 drives the rotating plate 403 to rotate, thereby opening the gas passage inside the transfer box 3 to the side of the designated fermenter, so that the supplied gas can enter the designated fermenter through the corresponding gas distribution pipe 2. Through the cooperation of the main gas pipe 1 and the gas distribution pipe 2 and the control of the valve assembly 4, the overall gas system pipeline is simple and clear, and easy to maintain. Air is left between the two fixed plates 404, so that the gas inside the main gas pipe 1 can flow through the gap between the fixed plates 404, thereby realizing the gas supply to the entire gas system.

[0036] Example 2

[0037] Reference Figure 1 , Figure 2 and Figure 6 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The limiting component 5 includes a fixed crossbar 501 fixedly installed on the upper surface of the transfer box 3. Two threaded shafts 502 are interposed inside the fixed crossbar 501. Rotating blocks 503 are meshed with the outer surfaces of the two threaded shafts 502.

[0038] Specifically, two threaded shafts 502 are fixedly connected to the outer surfaces of the two movable rods 402 on both sides, and two rotating blocks 503 are respectively disposed on both sides of the fixed crossbar 501. The fixed crossbar 501 has a through hole with a diameter larger than that of the threaded shafts 502. When the output ends of the two electric push rods 401 extend to their maximum distance, the end of the threaded shaft 502 near the rotating block 503 can abut against the outer surface of the adjacent movable rod 402. The two threaded shafts 502 are fixedly connected to the outer surfaces of the two movable rods 402, while the rotating blocks 503 are disposed on the outer surface of the threaded shaft 502 that meshes with it, away from the fixed crossbar 402. The fixed connecting rod 402 is positioned on one side, and the fixed crossbar 501 is set in the middle of the upper surface of the transfer box 3. The through hole supports the threaded shaft 502 and prevents it from tilting. When the output ends of the two electric push rods 401 extend to their maximum distance, the end of the threaded shaft 502 near the rotating block 503 can abut against the outer surface of the adjacent moving rod 402. At this time, the moving rod 402 drives the rotating rod to rotate to a vertical position, thereby sealing the air chamber on the inner side of the transfer box 3. This ensures that the setting of the threaded shaft 502 does not affect the opening and closing of the rotating plate 403 driven by the moving rod 402.

[0039] Furthermore, by rotating the corresponding rotating block 503, the rotating block 503 moves on the outer surface of the threaded shaft 502. When the electric push rod 401 drives the moving rod 402 to move, the rotating block 503 on the outer surface of the threaded shaft 502 abuts against the outer surface of the fixed crossbar 501. At this time, the moving rod 402 moves to its maximum distance, thereby limiting the maximum opening and closing degree that the rotating plate 403 can rotate, and avoiding excessive rotation that would cause the gas flow rate to be too fast and affect the control of the gas supply.

[0040] Working principle: When supplying gas to the multi-unit fermenters, the gas supply device connects to the main gas pipe 1, allowing gas to be delivered to the entire gas system through the gap between the two fixed plates 404 inside the transfer box 3. Then, depending on the specific situation of each fermenter, the valve assembly 4 is opened for gas supply. The fermenter requiring gas supply controls its corresponding valve assembly 4, which in turn moves the moving rod 402 via the electric push rod 401. The rectangular groove on the lower surface of the moving rod 402 engages with the protrusion 406, causing the protrusion 406 to rotate the rotating plate 403. This opens the gas path inside the transfer box 3 leading to the designated fermenter, allowing the supplied gas to enter the designated fermenter through the corresponding gas distribution pipe 2. Gas is supplied inside the tank. The overall gas system is simple and easy to maintain through the cooperation of the main gas pipe 1 and the branch gas pipe 2 and the control of the valve assembly 4. Before controlling the valve assembly 4, the corresponding rotating block 503 can be rotated to move on the outer surface of the threaded shaft 502. When the electric push rod 401 drives the moving rod 402 to move, the rotating block 503 on the outer surface of the threaded shaft 502 abuts against the outer surface of the fixed crossbar 501. At this time, the moving rod 402 moves to its maximum distance, thereby limiting the maximum opening and closing degree of the rotating plate 403. This avoids excessive rotation that would cause the gas flow rate to be too fast and affect the control of the gas supply. Finally, the gas supply control of the multi-unit fermenter is completed.

[0041] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
