Description

Technical Field

[0001] This utility model relates to the field of fermentation equipment technology, specifically to a fermentation tank outlet anti-sludge filter valve assembly. Background Technology

[0002] In fields such as bio-fermentation, food processing, and pharmaceutical production, fermenters are one of the core pieces of equipment used to cultivate microorganisms and carry out fermentation reactions. After fermentation is complete, the material in the fermenter needs to be discharged from the outlet for subsequent separation, purification, and other processes. However, a certain amount of sediment is generated during fermentation, such as microbial cell residue and unreacted raw material particles. This sediment flows to the outlet along with the material.

[0003] Existing fermenters typically only have ordinary valves at the discharge port to control the flow of material, lacking effective filtration and anti-clogging structures. During the discharge process, sediment easily accumulates at the valve, causing blockage. This not only affects discharge efficiency but also requires shutdown for valve disassembly and cleaning, increasing maintenance workload and production costs. Furthermore, while some fermenters have separate filters on the discharge pipe, these filters are separate from the valves, occupying significant space, and sediment may still accumulate in the pipe between the filter and valve, failing to fundamentally solve the blockage problem. Therefore, it is necessary to design a sediment-preventing filter valve assembly for the fermenter discharge port. Utility Model Content

[0028] Please see Figures 1-3 This utility model discloses a fermenter outlet anti-sludge filter valve assembly, comprising:

[0029] The valve body 1 has an inlet end 2 connected to the outlet of the fermentation tank at one end and an outlet end connected to the outlet pipe 3 at the other end. The valve body 1 has a material flow channel 4 for the flow of fermented materials. The valve body 1 also has a valve core 5 for controlling the opening and closing of the material flow channel. For easy inspection and maintenance, the top of the valve body 1 has an inspection port 18 connected to the material flow channel 4. The inspection port 18 has an inspection cover 19, which is detachably connected to the valve body 1 by bolts. Opening the inspection cover allows for the inspection and replacement of the components inside the valve body.

[0030] The filter mechanism 6 is detachably installed in the material flow channel 4 within the valve body, located between the feed end 2 and the valve core 5. The filter mechanism 6 includes a filter frame 7 and a filter screen 8. The filter frame 7 is sealed to the inner wall of the valve body 1, and the filter screen 8 is fixed to the filter frame 7 for filtering sediment from the material. The filter screen 8 is made of stainless steel, and its mesh diameter is 0.5-2mm. It effectively filters out most of the sediment from the material without excessively obstructing material flow, ensuring efficient discharge. The filter mechanism features a detachable design; when the filter screen is damaged or requires thorough cleaning, the inspection cover can be opened to remove the filter mechanism, making operation convenient.

[0031] An anti-clogging mechanism is provided inside the valve body 1 and corresponds to the filtering mechanism. The anti-clogging mechanism includes a cleaning scraper 9 and a scraper support 10. The cleaning scraper 9 is in contact with the surface of the filter screen 8. One end of the scraper support 10 is connected to the cleaning scraper 9, and the other end extends to the outside of the valve body 1. The cleaning scraper is made of polytetrafluoroethylene, which has good wear resistance, corrosion resistance and flexibility. Its edge is in close contact with the surface of the filter screen to ensure cleaning effect. The width of the cleaning scraper is adapted to the diameter of the filter screen to ensure that the cleaning scraper can cover the entire surface of the filter screen when it moves, avoiding cleaning dead corners.

[0032] The driving mechanism includes a first driving component and a second driving component. The first driving component is connected to the valve core 5 and is used to drive the valve core to rotate in order to open or close the material flow channel. The second driving component is connected to the outer end of the scraper bracket 10.

[0033] In this invention, the first driving assembly includes a drive motor 11, a reducer 12, and a transmission rod 13. The drive motor 11 is connected to the reducer 12, and the output end of the reducer 12 is connected to one end of the transmission rod 13. The other end of the transmission rod 13 extends into the valve body 1 and is fixedly connected to the valve core 5. The drive motor 11 drives the valve core 5 to rotate through the reducer 12 and the transmission rod 13. The valve core in this invention is a spherical valve core with a flow hole adapted to the material flow channel. When the first drive motor starts, it is decelerated by the first reducer and drives the transmission rod to rotate, which in turn drives the spherical valve core to rotate. When the flow hole aligns with the material flow channel, the material flow channel is open, and material discharge begins; when the flow hole is misaligned with the material flow channel, the material flow channel is closed, and material discharge stops. The control is precise and reliable.

[0034] In this invention, the second driving assembly includes a telescopic hydraulic cylinder 14 and a connecting column 15. The telescopic hydraulic cylinder 14 is installed outside the valve body 1. The telescopic end of the telescopic hydraulic cylinder 14 is connected to one end of the connecting column 15, and the other end of the connecting column 15 is connected to the scraper bracket 10. When the telescopic hydraulic cylinder operates, it can drive the scraper bracket and the cleaning scraper to move back and forth along the surface of the filter screen, which can clean the sediment attached to the filter screen, prevent the sediment from clogging the filter screen, and further improve the discharge efficiency.

[0035] Furthermore, in this invention, the bottom of the valve body 1 is provided with a slag discharge port 16, which is connected to the material flow channel 4 and located below the filtration mechanism. A slag discharge valve 17 is provided at the slag discharge port 16 for discharging the cleaned slag. The scraped slag will fall into the slag discharge port under the action of gravity. The slag discharge valve is a manual or electric valve. When the slag accumulates to a certain amount, the slag discharge valve can be opened to discharge the slag, which is simple to operate.

[0036] Working Principle: One end of the valve body is connected to the fermentation tank outlet, and the other end is connected to the discharge pipe. The internal valve core controls the opening and closing of the material channel. The first drive component drives the valve core to rotate, allowing material to enter the channel when it is open. The material first passes through the filtration mechanism between the inlet and the valve core. The filter frame seals the valve body, and the stainless steel filter screen traps sediment. After filtration, the material flows to the outlet. The anti-clogging mechanism is driven by the second drive component: a hydraulic cylinder drives the scraper bracket, causing the cleaning scraper attached to the filter screen to move back and forth, scraping away the sediment on the filter screen. The sediment falls into the slag discharge port at the bottom of the valve body, which can be opened to discharge it. The top inspection port facilitates filter screen replacement and internal maintenance, ensuring smooth discharge and reducing clogging and downtime for maintenance.

[0037] In summary, this utility model has a compact structure, can effectively filter sediment in materials, and can promptly clean sediment attached to the filter mechanism to avoid blockage, ensure smooth discharge, reduce maintenance costs, and improve fermentation production efficiency. It is suitable for the discharge system of various fermentation tanks.

[0038] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
