[0002] High-density bio-fermenters are specialized equipment used for high-density microbial fermentation. They achieve high cell density and efficient product generation by optimizing culture conditions. The core of this technology lies in precisely controlling parameters such as temperature, pH, and dissolved oxygen concentration, combined with an intelligent control system, to improve fermentation efficiency and product quality. Furthermore, when the pressure in the high-density bio-fermenter exceeds a certain value during operation, it can automatically release pressure through a safety relief structure to avoid the risk of explosion due to excessive pressure.

[0003] Currently, existing safety pressure relief structures for high-density bio-fermenters are generally used in conjunction with pressure gauges to achieve safe pressure relief. However, during the high-density bio-fermentation process, impurities (such as foam or suspended particulate impurities) are generated. These impurities may block the interior of the pressure relief cavity, affecting the normal pressure relief function of the safety pressure relief structure and posing certain safety hazards to the entire production and fermentation process, thus affecting the stable and safe operation of the equipment. Therefore, a new safety pressure relief structure for high-density bio-fermenters is proposed to address the above problems. Summary of the Invention

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.

[0014] Please see Figure 1-4 This utility model provides a technical solution: A safety pressure relief structure for a high-density bioreactor includes a fermenter body 1. An auxiliary port 2 is connected to the top of the fermenter body 1. A sealing cover 5 is installed on the top of the auxiliary port 2. A square tube 3 is connected to the right side of the sealing cover 5. A threaded bayonet 6, which is threadedly connected to the sealing cover 5, is connected to the bottom of the square tube 3. A pressure relief insert 7 is connected to the bottom of the threaded bayonet 6. A limiting guide rail 8 is fixedly connected to the bottom right side of the sealing cover 5. A connecting rod 9 is slidably connected to the inner side of the limiting guide rail 8. The bottom of the connecting rod 9 is fixedly connected to... A hollow gear 10 is connected, and an outer retaining ring 12 is fixedly connected to the bottom of the hollow gear 10. A first filter screen 11 is installed in the groove formed between the outer retaining ring 12 and the hollow gear 10. An inclined arc rod 13 is fixedly connected to the inner ring surface of the outer retaining ring 12. An inclined needle 14 is fixedly connected to the inclined surface of the inclined arc rod 13. A second filter screen 15 is inserted into the inner side of the pressure relief tube 7. A short column 16 is fixedly connected to the bottom of the second filter screen 15. A transmission gear 17 is meshed with the right side of the hollow gear 10. A micro motor 18 is provided directly above the transmission gear 17.

[0015] The right side of the adapter square tube 3 is equipped with a pressure gauge body 4 that is in a conductive configuration. The bottom of the adapter square tube 3 and the top of the sealing cover 5 are fitted together. The sealing cover 5 and the auxiliary pipe port 2 are detachably connected by multiple bolt fasteners. This structure facilitates the auxiliary sealing and plugging of the inlet end of the auxiliary pipe port 2 by the sealing cover 5. The top of the adapter square tube 3 is connected to a pressure relief lower pipe 19. An inner support plate 22 is fixedly connected to the inner side of the pressure relief lower pipe 19. A pressure relief top rod 21 is slidably connected in the middle slot of the inner support plate 22. The pressure relief top rod 21 has an inverted "T" shape. A pressure relief spring 23 is sleeved on the outside of the vertical end of the pressure relief top rod 21. The top end of the pressure relief top rod 21 is fixedly connected to a pressure relief upper pipe 20. The pressure relief upper pipe 20 and the pressure relief lower pipe 19 are in a sealed conductive configuration. The bottom end of the pressure relief spring 23 is fixedly connected to the top end of the inner support plate 22. Through the above structure, a complete pressure relief system can be formed. The structure is designed to allow the equipment to safely release pressure in a timely manner during fermentation. The upper end of the micro motor 18 is fixedly installed at the bottom of the sealed cover 5. One end of the transmission gear 17 is fixedly connected to the output end of the micro motor 18. The cooperation between the micro motor 18 and the transmission gear 17 drives the multiple rows of oblique needles 14 to rotate in a circular motion, breaking and removing the foam in the fermentation gas. The short column 16 extends downward through the central hole of the hollow gear 10. The short column 16 is fixedly connected to the first filter screen. The first and second filter screens are arranged parallel to each other. The four oblique arc rods 13 are arranged at an angle downward. There are four rows of oblique needles 14. The hollow gear 10 is sleeved on the outside of the pressure relief tube 7. The pressure relief tube 7 extends through the sealed cover 5 to the inside of the auxiliary pipe 2. The second filter screen can perform secondary filtration of the fermentation gas without affecting the normal delivery of fermentation gas into the pressure relief tube 7.

[0016] Workflow: The power required for the start-up and operation of the fermentation equipment in this utility model comes from an external power source. Before using the fermentation equipment, the sealing cover 5 is opened, and the raw materials required for fermentation are put into the fermentation tank body 1 through the auxiliary pipe 2. When using the high-density biological fermentation tank equipment, as the raw materials are put into the fermentation tank body 1 and the sealing cover 5 is installed in place to seal the auxiliary pipe 2, the stirring component installed at the center of the sealing cover 5 is started to assist in stirring the materials inside the fermentation tank body 1, so that they can undergo biochemical reactions under suitable conditions and with the assistance of stirring to achieve fermentation. During the fermentation process, under the conduction of the transfer square pipe 3, the fermentation equipment can be connected to the pressure gauge body to monitor the pressure value inside the fermentation tank body 1 in real time. Specifically, after the pressure relief pipe 7 extends through the sealing cover 5 and into the auxiliary pipe 2, the second filter 15 will fit into the interior of the pressure relief pipe 7. When the fermentation gas containing impurities rises into the interior of the pressure relief pipe 7, with the assistance of the sealing cover 5 and the limiting guide rail 8, When the micro motor 18 is started, it drives the transmission gear 17 to rotate. The hollow gear 10 then drives the connecting rod 9, outer retaining ring 12, first filter screen 11, short column 16, second filter screen 15, inclined arc rod 13, and inclined needle 14 to achieve relative circumferential rotation. At this time, the fermentation equipment can use multiple rows of inclined needles 14 to puncture and remove foam in the fermentation gas. At the same time, the multi-stage filtration structure formed by the first filter screen 11 and the second filter screen 15 further filters out suspended particulate impurities in the fermentation gas, preventing fermentation gas containing impurities from being directly sent into the pressure relief tube 7. This can easily lead to blockages inside the fermentation equipment. Then, the high-pressure fermentation gas will pass through the threaded bayonet 6 and the adapter square tube 3 and enter the pressure relief upper tube 20. With the assistance of the inner support plate 22, the high-pressure fermentation gas will overcome the rebound force generated by the pressure relief spring 23 and push the pressure relief rod 21 upward, so that the pressure relief upper tube 20 is lifted upward. A pressure relief gap is created between the pressure relief upper tube 20 and the pressure relief lower tube 19, and the high-pressure fermentation gas can be automatically depressurized and discharged, so as to achieve the purpose of safely protecting the normal operation of the entire fermentation equipment.

[0017] 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.
