Description

Technical Field

[0001] This utility model relates to the field of bio-fermentation tank technology, and in particular to a filter component for a bio-fermentation tank. Background Technology

[0002] Bio-fermentation is a biochemical process in which microorganisms, under specific conditions, transform organic matter into a target substance through metabolism. This biotechnology is widely used in food, pharmaceuticals, and environmental protection. Bio-fermentation technology not only improves product quality and promotes resource recycling but also drives green manufacturing and sustainable development. When materials require fermentation, they are introduced into a bio-fermentation tank. A bio-fermentation tank (also called a fermentation reactor or bioreactor) is a specially designed device used to conduct the bio-fermentation process in a controlled environment, increasing oxygen solubility through agitation to meet the aerobic needs of the microorganisms.

[0003] However, common bio-fermenters suffer from uneven mixing, which affects the subsequent fermentation of materials. At the same time, when filtering materials, they are prone to accumulating in one place of the filter structure, increasing the local filtration pressure and affecting the feeding and discharging of materials. Furthermore, if some filter structures are installed at the inlet and outlet, it will also affect disassembly and replacement. In view of this, we propose a filter component for bio-fermenters.

[0005] The technical solution of this utility model is as follows: A filtration assembly for a bio-fermentation tank includes a support structure and a controller. The support structure houses a rotating assembly, which includes a constant-temperature fermentation cylinder. A toothed ring is fitted onto the outer wall of the constant-temperature fermentation cylinder. A drive assembly is located below the toothed ring.

[0012] Compared with the prior art, the present invention has the following beneficial technical effects:

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] Example

[0021] like Figures 1 to 4 As shown, the present invention proposes a filtration assembly for a bio-fermentation tank, comprising a support structure 1 and a controller 7. A rotating assembly 2 is installed inside the support structure 1. The rotating assembly 2 includes a constant-temperature fermentation cylinder 21, sealing rings 22, stirring components 23, a feed pipe 24, a sealing plate 25, a solenoid valve 26, and a toothed ring 27. Two sealing rings 22 are symmetrically installed on both end faces of the constant-temperature fermentation cylinder 21 and inserted into symmetrically opened sealing grooves on both sides of the inner wall of the support structure 1, assisting the constant-temperature fermentation cylinder 21 in rotation and facilitating subsequent mixing. Multiple stirring components 23 are arranged inside the constant-temperature fermentation cylinder 21 in a ring array, which is beneficial for subsequent mixing of the contents of the constant-temperature fermentation cylinder 21. The materials are stirred and turned; the inlet end of the feed pipe 24 is inserted into the discharge port at the bottom of the constant temperature fermentation cylinder 21, which facilitates feeding and discharging of materials using the feed pipe 24; the sealing plate 25 and the solenoid valve 26 are both set inside the feed pipe 24, the sealing plate 25 is fixedly connected to the inner wall of the feed pipe 24, the middle part of the sealing plate 25 has an inlet and outlet, and the top and bottom walls of the sealing plate 25 are symmetrically provided with inclined surfaces. The solenoid valve 26 is installed in the inlet and outlet on the sealing plate 25, which facilitates the adjustment of the opening and closing state of the solenoid valve 26 according to the usage requirements; the toothed ring 27 is sleeved on the outer surface wall of the constant temperature fermentation cylinder 21, which facilitates the subsequent rotation of the constant temperature fermentation cylinder 21.

[0022] Furthermore, the stirring assembly 3 is mounted on the support structure 1. The stirring assembly 3 includes an air guide shaft 31, a stirring shaft 32, and an exhaust valve 33. First rotating holes are symmetrically opened on both sides of the support structure 1, so that one end of the air guide shaft 31 passes through the first rotating hole and is fixedly connected to the inner side wall of the support structure 1. Multiple exhaust valves 33 are symmetrically installed on the outer wall of the air guide shaft 31 and communicate with the inside of the air guide shaft 31 to facilitate oxygen supply to the support structure 1. An exhaust pressure reducing valve is connected to the other side wall of the support structure 1 to facilitate the fermentation of materials in the constant temperature fermentation tank 21. Multiple stirring shafts 32 are arranged in a ring array on the outer wall of the air guide shaft 31 and are set inside the air guide shaft 31. They are also staggered with the stirring structure on the stirring component 23 so that the stirring component 23 is not blocked by the stirring shaft 32 during rotation. Due to the rotatable setting of the stirring component 23, the stirring shaft 32 and the stirring component 23 cooperate to facilitate the stirring and fermentation of materials in the support structure 1. The uniformity and full contact of the materials are ensured by mechanically stirring the mixture.

[0023] Furthermore, the filtration mechanism 4 is installed on the feed tube 24. The filtration mechanism 4 includes a cylinder 40, a guide tube 41, a slider 42, a guide shaft 43, a spring 44, a vibration motor 45, a movable frame 46, a filter screen 47, a slide bar 48, and a moving part 49. The bottom end of the feed tube 24 is inserted into the guide tube 41. Multiple sliders 42 are welded to the four inner walls of the guide tube 41 and inserted into multiple grooves opened on the outer wall of the feed tube 24. The guide tube 41 moves up and down by utilizing the cooperation between the grooves and the sliders 42. Some sliders 42 have symmetrical sliding holes. Two guide shafts 43 are symmetrically arranged in the corresponding grooves and inserted into the corresponding sliding holes to assist the slider 42 in lifting and lowering, thus serving as guides. Multiple springs 44 are grouped in pairs, with the opposite ends of the two springs 44 in each group connected to the top and bottom walls of the slider 42, and the back ends of the two springs 44 connected to the top and bottom walls of the groove to assist the slider 42 in resetting. Each vibrating motor 45 is symmetrically installed on the outer walls of both sides of the guide tube 41 to assist the guide tube 41 in vibrating, facilitating vibration filtering of materials during feeding and discharging.

[0024] Two cylinders 40 are symmetrically mounted on the two side walls of the guide tube 41. The extension of the back wall of the movable component 49 is connected to the output end of the cylinder 40, facilitating the adjustment of the position of the movable component 49 under the drive of the cylinder 40. The movable frame 46 is inserted into the sliding opening on the guide tube 41. The front wall of the movable frame 46 is fixedly connected to the back wall of the movable component 49, which facilitates the adjustment of the position of the movable frame 46 under the pull of the movable component 49. Two slide bars 48 are symmetrically welded to the two side walls of the movable frame 46. Guide grooves are symmetrically opened on the two side walls of the sliding opening. Parts of the structure of the two slide bars 48 are respectively embedded in the insertion position. The filter screen 47 is placed in the corresponding guide groove, which helps the movable frame 46 move smoothly. The movable frame 46 has symmetrically opened storage grooves, and the bottom wall of the storage groove is open to avoid affecting the subsequent filtration of materials. The filter screen 47 is placed in the storage groove corresponding to the position and is located in the guide tube 41. The sliding mouth of part of the filter screen 46 is used to position the movable frame 46. At the same time, the filter screen 47 can be filtered under the action of the movable frame 46. Under the push of the cylinder 40, the movable frame 46 moves the filter screen 47 out of the guide tube 41, which facilitates the quick replacement of the filter screen 47 and makes it easier to clean, thus providing convenience for subsequent filtration work.

[0025] Furthermore, the top wall of the base plate 8 is fixedly connected to the bottom end of the support leg structure of the bracket structure 1, providing support for the bracket structure 1; the motor base 6 is fixedly installed on the top wall of the base plate 8, and the controller 7 is installed on the side wall of the motor base 6 for easy operation by staff; the drive assembly 5 is installed on the motor base 6, and the drive assembly 5 includes a forward and reverse motor 51, a rotating shaft 52, and a gear 53. The forward and reverse motor 51 is installed on the top wall of the motor base 6, and one end of the rotating shaft 52 is connected to the output end of the forward and reverse motor 51, facilitating rotation under the drive of the forward and reverse motor 51; the bracket A protruding rod is connected to the bottom wall of part of the support structure of structure 1. A second rotating hole is opened on the protruding rod, and an auxiliary bearing is embedded in the second rotating hole. The other end of the rotating shaft 52 is inserted into the second rotating hole, so that the auxiliary bearing is sleeved on the outer surface wall of the rotating shaft 52, which stabilizes and assists the rotation of the other end of the rotating shaft 52. The gear 53 is located below the gear ring 27 and is fixedly sleeved on the outer surface wall of the rotating shaft 52. It also meshes with the gear ring 27, which facilitates the rotation of the constant temperature fermentation cylinder 21 by the gear ring 27, which is beneficial for subsequent turning and mixing of materials.

[0026] In this embodiment, when materials need to be introduced into the constant temperature fermentation cylinder 21, the forward and reverse motor 51 is started to drive the rotating shaft 52 to rotate the gear 53, so that the gear ring 27 meshes with the gear 53 to drive the constant temperature fermentation cylinder 21 to rotate, adjusting the position of the guide tube 24 to an upward tilted state, which facilitates the introduction of the materials to be fermented into the constant temperature fermentation cylinder 21. When the materials are introduced into the constant temperature fermentation cylinder 21, the solenoid valve 26 is in the open state, and the vibration motor 45 is started to drive the guide tube 41 to make the movable frame 46 and the filter screen 47 vibrate. Due to the vibration of the filter screen 47, the local filtration pressure of the filter screen 47 during the filtration process is reduced, which may affect the filtration operation and prevent it from affecting the material introduction into the constant temperature fermentation cylinder 21. In addition, with the cooperation of the spring 44, the guide shaft 43 and the slider 42, the guide tube 41 is assisted to vibrate on the guide tube 24 to avoid reducing the connection between the guide tube 24 and the guide tube 41. Due to the rotatable setting of the constant temperature fermentation cylinder 21, the stirring element 23 is able to move within the constant temperature fermentation cylinder 21. Driven by motor 1, the stirring shaft 32 mixes the fermentation materials, improving the uniformity and contact effect during fermentation. When discharge is required, the forward and reverse motors 51 drive the gear 53 and gear ring 27 to rotate the constant temperature fermentation cylinder 21, adjusting the guide pipe 24 to face downwards. At this time, the solenoid valve 26 is closed to prevent material discharge during the rotation of the constant temperature fermentation cylinder 21. Since the vibration motor 45 can drive the guide pipe 41 to vibrate, it reduces the impact of material accumulation on the filtration operation and facilitates the feeding and discharging of the constant temperature fermentation cylinder 21. When the filter screen 47 needs to be cleaned or replaced, the cylinder 40 pushes the moving part 49 to move the movable frame 46, allowing the filter screen 47 to be moved out of the guide pipe 41 for quick disassembly and replacement. The two storage slots on the movable frame 46 allow the staff to place a filter screen 47 in the storage slots, enabling quick replacement during disassembly and facilitating subsequent feeding and discharging filtration.
