[0015] Compared with the prior art, the technical solution of the present invention has the following advantages: (1) By starting the motor body and the electric reciprocating push rod, the present invention can, with the cooperation of the filtering and anti-blocking assembly, make the filter material cylinder reciprocate up and down and rotate continuously. At the same time, under the impact of water flow, the impurities accumulated on the surface of the funnel filter net slide down from the inclined surface of the funnel filter net. The blocked filter net needs to be frequently cleaned or replaced, which not only increases the maintenance cost but also affects the continuous operation of the production line. However, the fermentation liquid filtering device reduces the risk of filter net blockage by removing impurities in advance, thereby reducing the downtime and maintenance cost. Moreover, the setting of the cylindrical filter net can ensure that the filtering efficiency is not affected during the process of removing the impurities accumulated on the surface of the funnel filter net, avoiding downtime caused by the blockage of the funnel filter net. (2) The present invention, through the cooperation between the filter anti-blocking component and the anti-deposition component, can enable multiple side scrapers to push away the impurities on the side of the cylindrical filter screen during the process of removing impurities accumulated on the surface of the funnel filter screen, so as to prevent the accumulation of impurities and cause them to enter the gap between the sealing ring and the sealing top cylinder, thereby causing the sealing performance of the sealing ring to decrease. By regularly cleaning the impurities on the surface of the filter screen, especially using the side scrapers to push away the impurities, the wear and corrosion of the filter screen by the impurities can be reduced, which helps to extend the service life of the filter screen and reduce the replacement frequency, thereby reducing maintenance costs. At the same time, keeping the sealing ring clean and having good sealing performance also helps to extend the service life of the entire filtration system. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] When filtering the fermentation broth, the electric reciprocating push rod 12 and the motor body 11 can be started. The motor body 11 can drive the spring rod 26 to rotate under the connection of the rotating shaft body 111. At this time, the support plate 21 can drive the filter material cylinder 27 to rotate synchronously under the connection of the guide rail rod 211. At this time, the support plate 21 can slide on the inner wall of the filter device body 1. At the same time, the start of the electric reciprocating push rod 12 can drive the filter material cylinder 27 to reciprocate axially on the outer walls of the plurality of guide rail rods 211. At this time, the filter material cylinder 27 can reciprocate and slide inside the filter device body 1 and continuously rotate. During this process, the fermentation broth can enter the inside of the cylindrical filter net 23 under the filtration of the plurality of funnel filter nets 25, and enter the central discharge pipe 28 through the feeding pipe 22 and the side discharge pipe 221, and finally be discharged through the fixed discharge pipe 29. The reciprocating sliding of the filter material cylinder 27 can improve the filtration efficiency of the fermentation broth. For example Figure 5 , when the filter material cylinder 27 slides downward, the plurality of funnel filter nets 25 can move upward relative to the filter material cylinder 27. When the cylindrical filter net 23 completely moves into the filter material cylinder 27, the fermentation broth can enter its inside through the cylindrical filter net 23, and the impurities adhered to the arc-shaped surface of the funnel filter net 25 can fall to the periphery of the plurality of side scraping rods 34 under the impact of water flow. When the filter material cylinder 27 slides upward, the sealing top cylinder 24 can move downward relative to the filter material cylinder 27. At this time, the scraping ring fixed on the inner wall of the inner sealing scraping cylinder 271 can scrape the impurities on the surface of the cylindrical filter net 23. During the downward movement of the filter material cylinder 27, the guiding block 31 can enter the arc-shaped guiding groove 321 through the opening groove. During the sliding of the guiding block 31 inside the arc-shaped guiding groove 321, it can drive the guiding connection cylinder 32 to rotate around the connection position with the filter material cylinder 27, thereby driving the plurality of side scraping rods 34 fixedly connected with the upper fixing ring 33 to rotate. The plurality of side scraping rods 34 can push aside the impurities on the periphery of the cylindrical filter net 23 to prevent the accumulation of impurities from entering the gap between the sealing ring 272 and the sealing top cylinder 24, thereby preventing the sealing performance of the sealing ring 272 from being reduced.

[0022] Working principle and usage process of the present invention: When filtering the fermentation broth, the electric reciprocating push rod 12 and the motor body 11 can be started. The motor body 11 can drive the spring rod 26 to rotate under the connection of the rotating shaft body 111. At this time, the support disk 21 can drive the filter cartridge 27 to rotate synchronously under the connection of the guide rail rod 211. At this time, the support disk 21 can slide on the inner wall of the filtering device body 1. At the same time, the start of the electric reciprocating push rod 12 can drive the filter cartridge 27 to reciprocate axially and slide on the outer walls of multiple guide rail rods 211. At this time, the filter cartridge 27 can reciprocate and slide inside the filtering device body 1 and continuously rotate. During this process, the fermentation broth can enter the inside of the cylindrical filter screen 23 through the filtration of multiple funnel filter screens 25, and enter the inside of the central discharge pipe 28 through the feeding pipe 22 and the side discharge pipe 221, and finally be discharged through the fixed discharge pipe 29. When the filter cartridge 27 slides downward, multiple funnel filter screens 25 can move upward relative to the filter cartridge 27. When the cylindrical filter screen 23 completely moves into the filter cartridge 27, the fermentation broth can enter its inside through the cylindrical filter screen 23, and the impurities adhering to the arc surface of the funnel filter screen 25 can fall to the periphery of multiple side scraping rods 34 under the impact of water flow. When the filter cartridge 27 slides upward, the sealing top cylinder 24 can move downward relative to the filter cartridge 27. At this time, the scraping ring fixed on the inner wall of the inner sealing scraping cylinder 271 can scrape the impurities on the surface of the cylindrical filter screen 23, which can prevent the surface of the funnel filter screen 25 from being blocked. And during the reciprocating up and down sliding of the cylindrical filter screen 23, under the elastic force of the spring, the bottom of the funnel filter screen 25 can be closely attached to the top end of the sealing top cylinder 24. And during the downward movement of the filter cartridge 27, the guide block 31 can enter the arc-shaped guide groove 321 through the opening groove. During the process of the guide block 31 sliding in the arc-shaped guide groove 321, it can drive the guide connection cylinder 32 to rotate around the connection position with the filter cartridge 27, thereby driving multiple side scraping rods 34 fixedly connected to the upper fixing ring 33 to rotate. Multiple side scraping rods 34 can push aside the impurities on the periphery of the cylindrical filter screen 23.
