The bottom end of the fixing bolt 9 extends into the inside of the positioning ring 7. A filter tube 10 is provided inside the positioning ring 7. The cross-section of the filter tube 10 is smaller than the cross-section of the sleeve 6. The left side of the filter tube 10 extends into the inside of the sleeve 6. A cover plate 11 is provided on the right side of the filter tube 10. A filter groove 12 is provided on the left side of the bottom end of the filter tube 10. A filter screen 13 is installed inside the filter groove 12. A drain pipe 14 is installed at the bottom end of the filter tank 1. Support frames 15 are installed on both sides of the bottom end of the filter tank 1.

[0024] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, during use, the fermentation broth enters the infusion pipe 2 through the inlet pipe 5 and then enters the filter pipe 10 connected to it. With the assistance of the filter screen 13, it undergoes screening and filtration. If the motor 3 is started, the spiral conveying rod 4 inside the infusion pipe 2 can be driven to rotate. The rotating spiral conveying rod 4 can help push the material into the filter pipe 10. At the same time, the rotating drain pipe 14 can push the impurities that have not been filtered out inside the filter pipe 10 and drive them to accumulate at the end of the infusion pipe 2. The cover plate 11 is installed at the end of the filter pipe 10 by threads. After rotating the cover plate 11 to remove it, the accumulated debris inside can be cleaned. If the fixing bolt 9 is loosened and the fixing of the filter pipe 10 is released, the filter pipe 10 can be pulled out from the inside of the positioning ring 7. In this way, the filter pipe 10 can be replaced.

[0025] A side box 16 is installed at the bottom left side of the filter tank 1. A feed pump 17 is installed inside the side box 16. A liquid extraction pipe 18 is installed on the right side of the feed pump 17. The liquid extraction pipe 18 extends into the filter tank 1 on the right side. A circulation pipe 19 is installed at the top of the feed pump 17. The top of the circulation pipe 19 is fixedly connected to the bottom of the liquid delivery pipe 2. A door 20 is movably installed on the left side of the side box 16.

[0026] Specifically, such as Figure 1As shown, when in use, the feed pump 17 is started, and the fermentation liquid filtered inside the filter tank 1 can be extracted with the help of the liquid extraction pipe 18, and then transported back to the feed pipe 2 through the circulation pipe 19 for another filtration and screening operation.

[0027] The top of the filter tank 1 is provided with a through groove 21, and the inside of the through groove 21 is provided with an installation ring 22. The inside of the through groove 21 is provided with an internal thread, and the surface of the installation ring 22 is provided with an external thread. A transparent plate 23 is installed inside the installation ring 22. Two sets of transparent plates 23 are installed inside the installation ring 22 and the two sets of transparent plates 23 are distributed in parallel. A limiting platform 24 is fixed at the top of the installation ring 22, and an observation window 25 is provided on the surface of the top of the limiting platform 24.

[0028] Specifically, such as Figure 4 As shown, during use, the state of the fermentation liquid inside the filter tank 1 can be directly observed through the observation window 25. If the limiting platform 24 is rotated, the installation ring 22 can be removed after the threads between it and the through groove 21 are separated. At this time, the through groove 21 can be used as an auxiliary feeding port for multi-pipe feeding operation.

[0029] Working principle: During use, the material enters the inlet pipe 2 through the inlet pipe 5. The inlet pipe 2 and the filter pipe 10 are connected with the sleeve 6. The fermentation broth can flow into the filter pipe 10 through the inlet pipe 2. After being filtered by the filter screen 13, it flows into the filter tank 1. During this process, the motor 3 can be started. Starting the motor 3 can drive the spiral conveyor rod 4 inside the inlet pipe 2 to rotate. The rotating spiral conveyor rod 4 can help push the material into the filter pipe 10. At the same time, the rotating outlet pipe 14 can push the impurities that have not been filtered out inside the filter pipe 10 and drive them to accumulate at the end of the inlet pipe 2. The cover plate 11 is installed at the end of the filter pipe 10 by threads. After rotating the cover plate 11 to remove it, the accumulated material inside can be cleaned. If the fixing bolt 9 is loosened and the filter tube 10 is released, the filter tube 10 can be pulled out from the inside of the positioning ring 7. In this way, the filter tube 10 can be replaced. With the help of the observation window 25, the state of the fermentation liquid inside the filter tank 1 can be directly observed to determine the filtration state of the fermentation liquid. If the limiting platform 24 is rotated, the installation ring 22 can be removed after the threads between it and the through groove 21 are separated. At this time, the through groove 21 can be used as an auxiliary feeding port for multi-pipe feeding operation. If the conveying pump 17 is started, the fermentation liquid filtered inside the filter tank 1 can be extracted with the help of the liquid extraction pipe 18 and transported back to the liquid delivery pipe 2 through the circulation pipe 19 for another filtration and screening operation, so as to realize the function of circulating treatment of fermentation liquid.
