Description

Technical Field

[0001] This utility model relates to the field of biotechnology, specifically to a fermentation substrate feeding device for the production of Bacillus subtilis. Background Technology

[0002] Bacillus subtilis grows and reproduces rapidly. Its colonies have a rough, opaque surface and are off-white or slightly yellow. When grown in liquid culture, it often forms a wrinkled mold. It is an aerobic bacterium that can utilize proteins, various sugars, and starch, and decomposes tryptophan to form indole.

[0003] According to the patent application published on the Internet, a fermentation substrate feeding device for Bacillus subtilis production (authorization announcement number: CN 213949697 U) describes "This utility model relates to the field of biotechnology and discloses a fermentation substrate feeding device for Bacillus subtilis production. The feeding motor drives the rotating shaft and spiral blade to rotate, thereby automatically feeding the substrate. The storage tank, return air pipe, feeding mechanism, feeding hose and sealing end cap constitute a closed feeding system. During the feeding process, the dusty air in the fermentation tank flows back to the storage tank through the return air pipe and is filtered by the air filtration mechanism, thereby preventing dust diffusion and protecting the working environment. This solves the problem of low feeding efficiency of fermentation substrate and the generation of a large amount of dust, which pollutes the production environment. By opening several conical grooves on the side wall of the cover, a slider is slidably connected in the groove. The slider is fixedly connected to the clamping plate, thereby clamping the fermentation tank, which facilitates the fixing of the sealing end cap. At the same time, during the clamping process, the slider slides inward and presses down on the cover, thereby ensuring the sealing of the sealing end cap."

[0004] Based on the above, the applicant believes the following deficiencies exist:

[0005] The fermentation substrate feeding device for Bacillus subtilis production is equipped with casters to allow the device to move during use. However, it lacks a function to reinforce the device during the feeding process, which may cause shaking and displacement, posing certain safety hazards and hindering the further progress of the feeding work.

[0028] This utility model provides the following technical solution:

[0029] Example 1

[0030] Combination Figures 1 to 6 A fermentation substrate feeding device for Bacillus subtilis production includes a feeding box 1, a conveying auger 3 fixedly connected to the bottom of the feeding box 1, a conveying pipe 4 fixedly connected to the top of the conveying auger 3, a feeding hose 5 fixedly connected to the top of the conveying pipe 4, a return air pipe 6 fixedly connected to the bottom of the feeding hose 5, a filter mechanism 8 inside the feeding box 1, a moving mechanism 2 at the bottom of the feeding box 1, and a cover plate 7 hinged to the top of the feeding box 1.

[0031] The moving mechanism 2 includes a moving leg 21, which is fixedly connected to the bottom of the feeding box 1. A long box 22 is fixedly connected to the inner side of the moving leg 21. A threaded rod 23 is rotatably connected to the inner wall of the long box 22. A long plate 24 is threadedly connected to the outer wall of the threaded rod 23. A long block 27 is fixedly connected to the bottom of the long plate 24. A reinforcing plate 28 is fixedly connected to the bottom of the long block 27. A worm gear 25 is fixedly connected to the outer wall of the threaded rod 23. A worm 26 is meshed on the outer ring of the worm gear 25. A motor 29 is fixedly connected to the front end of the worm 26.

[0032] Furthermore, the bottom of the long box 22 is provided with a movable opening, through which the long block 27 passes and moves, allowing the long block 27 to move through the movable opening.

[0033] Furthermore, the long plate 24 is slidably connected to the inner wall of the long box 22, and the worm gear 26 passes through the long box 22 and rotates, providing stable support for the worm gear 26.

[0034] Furthermore, there are two long boxes 22, and the motor 29 is fixedly connected to the front of one of the two long boxes 22 to provide stable support for the motor 29.

[0035] Example 2

[0036] See Figures 1 to 6 Furthermore, based on Embodiment 1, the filter mechanism 8 further includes a support plate 81, which is fixedly connected to the outside of the feeding box 1. A baffle 82 is provided on the top of the support plate 81. A limiting frame 84 is fixedly connected to the inner wall of the feeding box 1. A filter frame 83 is slidably connected to the inner wall of the limiting frame 84. A limiting plate 85 is fixedly connected to the back of the feeding box 1 to facilitate the disassembly and cleaning of the filter frame 83.

[0037] Furthermore, a short shaft is rotatably connected inside the baffle 82, and the short shaft is fixedly connected to the front of the feeding box 1, so that the filter frame 83 can block the filter frame 83.

[0038] Furthermore, the back of the filter frame 83 is in contact with the front of the limiting plate 85. Both the front and back of the filter frame 83 are provided with exhaust holes, and both the front and back of the feeding box 1 are provided with openings, so that the exhaust gas can be discharged better.

[0039] In actual operation, when this device is used, the operator first moves the device to the feeding position of Bacillus subtilis fermentation substrate, then connects the feeding hose 5 to the feeding position. The moving leg 21 enables movement, and the self-locking wheel provides initial self-locking. Then, the motor 29 can be started. The output of the motor 29 drives the worm 26 to rotate. Since the worm 26 and the worm wheel 25 are meshed, the worm wheel 25 drives the threaded rod 23 to rotate. The long plate 24 can slide and limit the movement on the inner wall of the long box 22, thus converting the rotational motion of the threaded rod 23 into the linear motion of the long plate 24. The long plate 24 can drive the reinforcing plate 28 to descend via the long block 27, allowing the bottom of the reinforcing plate 28 to contact the ground. This provides reinforcement during the feeding process, reducing swaying and deviation, lowering potential safety hazards, and facilitating further feeding operations.

[0040] When the conveyor auger 3 is started, the Bacillus subtilis fermentation material at the bottom of the feeding box 1 is transported to the inside of the conveying pipe 4, and then to the inside of the feeding hose 5, thus achieving the purpose of feeding. The waste gas generated during the feeding process will be discharged into the inside of the filter frame 83 through the return air pipe 6. The filter frame 83 can filter and purify the substances contained in the waste gas. The rotating baffle 82 moves in a circle along the axis of the short axis, so that the baffle 82 is no longer in front of the filter frame 83. At this time, the filter frame 83 can be pulled forward, so that the filter frame 83 can be pulled out from inside the limiting frame 84, thus realizing the disassembly of the filter frame 83. This makes it convenient for the staff to disassemble, replace and clean the filter frame 83, achieving good cleaning efficiency and facilitating operation. The purified waste gas will be discharged through the exhaust hole opened in the filter frame 83, and the limiting plate 85 can block the filter frame 83.
