Description

Technical Field

[0001] This utility model relates to the field of microbial fermentation technology, and in particular to an inoculation device for microbial fermentation. Background Technology

[0002] Microbial fermentation refers to the process by which microorganisms transform raw materials into products needed by humans through metabolic pathways in a specific environment. This process depends not only on the genetic characteristics of the strains but is also significantly affected by culture conditions (such as temperature, pH, and oxygen supply).

[0003] In the existing technology, there is an inoculation device for a microbial fermenter with application number CN202420241358.2. This application does not require reducing the tank pressure to zero or depressurizing it. The inoculation cup is directly connected to the top inlet of the fermenter. After pouring the inoculum into the inoculation cup, the cover is closed and the ball valve is opened. At this time, the return pipe connects the fermenter and the inoculation cup, thereby balancing the pressure between the two chambers. This allows the inoculum in the inoculation cup to flow smoothly into the fermenter. The inoculum is poured into the inoculation cup under the protection of the flame ring, which greatly reduces the risk of contamination during inoculation. However, after inoculation, the staff needs to extinguish the flame ring with a wet towel, which is highly dangerous. Improper operation can easily lead to injury to the staff, and the flame is not easy to extinguish. Utility Model Content

[0004] The purpose of this invention is to provide an inoculation device for microbial fermentation that can solve the problems mentioned in the background art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an inoculation device for microbial fermentation, comprising a fermenter, and further comprising: An inoculation assembly, which is installed at the top of the fermenter and is used to inoculate the fermenter; The inoculation component includes: A connecting pipe is fixedly installed at the top of the fermenter. A connecting pipe is inserted inside the connecting pipe. An inoculation cup is fixedly installed at the upper end of the connecting pipe. A protective ring is fixedly installed at the upper outer side of the inoculation cup. A through groove is opened at the upper end of the protective ring. An adjusting ring is rotatably connected to the outer side of the protective ring. A sealing plate is fixedly installed at the upper end of the adjusting ring. Limit blocks are fixedly installed at the front and rear sides of the lower end of the protective ring. The front and rear ends of the adjusting ring have slots. A locking block is slidably connected inside the limiting block. A spring is provided between the locking block and the limiting block.

[0006] In the above scheme, after the adjusting ring is rotated to the designated position, the locking block aligns with the slot, and the spring pushes the locking block into the slot to lock the adjusting ring and ensure the stability of the adjusting ring during use.

[0007] A further feature of this invention includes: A locking component, which is installed on the outside of the inoculation component, is used to lock the internal structure of the inoculation component.

[0008] The locking component includes: A positioning ring is fixedly installed on the outside of the connecting pipe. A sealing ring is glued to the lower end of the positioning ring. A locking sleeve is rotatably connected to the outside of the connecting pipe at the upper end of the positioning ring. The locking sleeve is threadedly connected to the outside of the connecting pipe.

[0009] In the above scheme, when installing the inoculation component, the connecting tube is inserted into the inside of the connecting tube, and the locking sleeve is screwed onto the outside of the connecting tube. As the locking sleeve is screwed down, the positioning ring is pushed down, so that the sealing ring on the positioning ring is tightly attached to the connecting tube, ensuring the sealing of the connection between the connecting tube and the connecting tube.

[0010] A further feature of this invention includes: A cover assembly is installed on the upper part of the fermenter.

[0011] The cover plate assembly includes: A cover plate is attached to the upper end of the inoculation cup. A locking block is fixedly installed inside the upper end of the inoculation cup. A limiting sleeve is fixedly installed at the lower end of the cover plate. Limiting grooves are opened on the left and right sides of the limiting sleeve. The limiting grooves are L-shaped.

[0012] In the above scheme, the limiting groove on the limiting sleeve is aligned with the locking block, and then the cover plate is pushed to insert the limiting sleeve into the inoculation cup. The locking block slides into the limiting groove at the same time. Then the cover plate is rotated to drive the limiting sleeve to rotate, so that the locking block slides into the depth of the L-shaped limiting groove, thereby locking the cover plate.

[0013] The beneficial effects of this utility model are: The inoculation assembly of this invention uses a protective ring and a through groove to form a flame ring on the outside of the inoculation cup, killing bacteria in the surrounding air and reducing the risk of bacterial contamination. At the same time, the adjusting ring and the sealing plate work together to prevent outside air from entering the protective ring, thereby extinguishing the burning alcohol inside the protective ring, facilitating the extinguishing of the flame ring, improving safety when extinguishing the flame, and sealing the protective ring to prevent the evaporation of residual alcohol.

[0014] The locking component of this invention, through the cooperation of the locking sleeve and the positioning ring, facilitates the disassembly and installation of the inoculation component, thereby facilitating the cleaning of the inoculation component. At the same time, it ensures the airtightness of the inoculation component and the fermenter after installation, preventing external bacteria from entering the fermenter through the connection between the connecting pipe and the docking pipe, thus preventing contamination of the fermenter.

[0015] The cover plate assembly of this utility model locks the limiting sleeve by cooperating with the cover plate, which facilitates the disassembly and installation of the limiting sleeve and the sealing of the inoculation cup, preventing dust and impurities from entering the inoculation cup.

[0020] Reference Figure 1-5 An inoculation device for microbial fermentation includes a fermenter 1, an inoculation component 2, a locking component 3, and a cover plate component 4. The inoculation component 2 is installed on the upper end of the fermenter 1 for inoculating the fermenter 1. The locking component 3 is installed on the outside of the inoculation component 2 for locking the internal structure of the inoculation component 2. The cover plate component 4 is installed on the upper end of the fermenter 1.

[0021] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The inoculation assembly 2 includes: a connecting pipe 201 fixedly installed on the upper end of the fermenter 1; a connecting pipe 202 inserted inside the connecting pipe 201; an inoculation cup 203 fixedly installed on the upper end of the connecting pipe 202; a protective ring 204 fixedly installed on the upper outer side of the inoculation cup 203; a through groove 205 opened on the upper end of the protective ring 204; an adjusting ring 206 rotatably connected to the outer side of the protective ring 204; a sealing plate 207 fixedly installed on the upper end of the adjusting ring 206; and a limiting plate fixedly installed on the front and rear sides of the lower end of the protective ring 204. Positioning block 208, adjusting ring 206 has slots 209 at the front and rear ends, limiting block 208 has a sliding block 210 inside, and a spring 211 is provided between the block 210 and the limiting block 208. Locking component 3 includes: positioning ring 301 fixedly installed on the outside of connecting pipe 202, sealing ring 302 glued to the lower end of positioning ring 301, and locking sleeve 303 rotatably connected to the outside of connecting pipe 202 at the upper end of positioning ring 301. Locking sleeve 303 is threadedly connected to the outside of connecting pipe 201.

[0022] In this invention, when inoculating the inside of the fermenter 1, rotating the adjusting ring 206 causes the sealing plate 207 to rotate synchronously. One end of the locking block 210 has a semi-circular design. When the adjusting ring 206 rotates, it presses against the semi-circular side of the locking block 210, causing the locking block 210 to slide into the limiting block 208 and compressing the spring 211. When the adjusting ring 206 rotates to the designated position, the locking groove 209 aligns with the locking block 210, and the spring 211 resets, pushing the locking block 210 into the locking groove 209, thus locking the adjusting ring 206 and ensuring its stability. 6. Stability during use: Align the slots on the sealing plate 207 with the through-slots 205 on the protective ring 204, allowing the interior of the protective ring 204 to communicate with the outside. The protective ring 204 contains alcohol, which is ignited through the through-slot 205, creating a flame ring on the outside of the inoculation cup 203. Then, the inoculum is poured into the inoculation cup 203. The flame ring kills airborne bacteria, reducing the risk of contamination. The inoculum inside the inoculation cup 203 enters the connecting pipe 201 through the connecting pipe 202, and then enters the fermenter 1. The inoculation assembly 204 is used to inoculate fermenter 1. After inoculation, rotating the adjusting ring 206 rotates the sealing plate 207, causing the sealing plate 207 to cover the through groove 205, preventing outside air from entering the protective ring 204 and thus extinguishing the burning alcohol inside the protective ring 204. This facilitates the extinguishing of the flame ring and improves safety during flame extinguishing. Simultaneously, it seals the protective ring 204 to prevent the evaporation of residual alcohol. When disassembling the inoculation assembly 2, the locking sleeve 303 is screwed up, causing it to spiral upwards outside the connecting pipe 201, locking the inoculation assembly 2. The fixing sleeve 303 releases the pressure on the positioning ring 301, and then pulls up the inoculation cup 203, causing the connecting tube 202 to slide upwards, thereby pulling out the inside of the connecting tube 201. This also causes the sealing ring 302 on the positioning ring 301 to disengage from the connecting tube 201, making it easier to disassemble and install the inoculation assembly 2. This facilitates the cleaning of the inoculation assembly 2 and ensures the airtightness of the inoculation assembly 2 and the fermenter 1 after installation, preventing external bacteria from entering the inside of the fermenter 1 through the connection between the connecting tube 202 and the connecting tube 201, thus preventing contamination inside the fermenter 1.

[0023] Reference Figure 1 and Figure 5 The cover plate assembly 4 includes: a cover plate 401 that overlaps the upper end of the inoculation cup 203; a locking block 402 that is fixedly installed inside the upper end of the inoculation cup 203; a limiting sleeve 403 that is fixedly installed at the lower end of the cover plate 401; and limiting grooves 404 that are L-shaped on the left and right sides of the limiting sleeve 403. In this invention, after the inoculation cup 203 is used, the cover plate 401 is removed so that the limiting groove 404 on the limiting sleeve 403 is aligned with the locking block 402. Then, the limiting sleeve 403 on the cover plate 401 is inserted into the inoculation cup 203, and the locking block 402 is simultaneously inserted into the limiting groove 404. Then, the cover plate 401 is rotated, thereby driving the locking block 402 to rotate inside the L-shaped limiting groove 404, thereby locking the limiting sleeve 403. This facilitates the disassembly and installation of the limiting sleeve 403, and facilitates the sealing of the inoculation cup 203, preventing dust and impurities from entering the inoculation cup 203.

[0024] Working principle: When inoculating the inside of fermenter 1, rotating the adjusting ring 206 causes the sealing plate 207 to rotate synchronously. One end of the locking block 210 has a semi-circular design. When the adjusting ring 206 rotates, it presses against the semi-circular side of the locking block 210, causing it to slide into the limiting block 208 and compressing the spring 211. When the adjusting ring 206 rotates to the designated position, the locking groove 209 aligns with the locking block 210, and the spring 211 resets, pushing the locking block 210 into the locking groove 209, thus locking the adjusting ring 206 and ensuring its stability during use. The slot on the sealing plate 207 is aligned with the through groove 205 on the protective ring 204, allowing the inside of the protective ring 204 to communicate with the outside. The protective ring 204 contains alcohol. The alcohol in the protective ring 204 is ignited through the through groove 205, forming a flame ring on the outside of the inoculation cup 203. Then, the inoculum is poured into the inoculation cup 203. The flame ring kills the surrounding airborne bacteria, reducing the risk of contamination. The inoculum inside the inoculation cup 203 enters the connecting pipe 201 through the connecting pipe 202, and then enters the fermenter 1, thus inoculating the fermenter 1.

[0025] When extinguishing the flame inside the protective ring 204, rotate the adjusting ring 206 to drive the sealing plate 207 to rotate, so that the sealing plate 207 covers the through groove 205, preventing outside air from entering the interior of the protective ring 204, thereby extinguishing the burning alcohol inside the protective ring 204.

[0026] When it is necessary to disassemble the inoculation assembly 2, turn the locking sleeve 303 so that the locking sleeve 303 spirals up on the outside of the connecting tube 201, so that the locking sleeve 303 releases the pressure on the positioning ring 301. Then pull up the inoculation cup 203, which drives the connecting tube 202 to slide up, thereby pulling out the inside of the connecting tube 201 and causing the sealing ring 302 on the positioning ring 301 to disengage from the connecting tube 201, thus realizing the disassembly of the inoculation assembly 2.

[0027] After the inoculation cup 203 is used, remove the cover plate 401 and align the limiting groove 404 on the limiting sleeve 403 with the locking block 402. Then, insert the limiting sleeve 403 on the cover plate 401 into the inoculation cup 203, and simultaneously insert the locking block 402 into the limiting groove 404. Then, rotate the cover plate 401, thereby driving the locking block 402 to rotate inside the L-shaped limiting groove 404, thereby locking the limiting sleeve 403 and preventing dust and impurities from entering the inoculation cup 203.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
