Abstract
Description
Technical Field
[0001] This utility model relates to the field of microbial fermentation, specifically a simple microbial fermentation device for aquaculture. Background Technology
[0002] In aquaculture, the fermentation of microbial agents is a crucial step in improving water quality and promoting the health of farmed organisms. However, in traditional fermentation processes, uneven temperature distribution and significant differences in colony density occur in different areas of the fermentation tank, leading to low local fermentation efficiency and even the accumulation of microbial metabolites that inhibit the overall fermentation process. To address this issue, existing technologies generally employ stirring devices to promote uniform mixing of materials within the tank, thereby optimizing microbial distribution and improving heat transfer efficiency.
[0003] Currently, most fermentation mixing devices on the market adopt an independent design, meaning each fermentation tank is equipped with its own mixing structure consisting of a drive motor, mixing shaft, and blades. This design has the following drawbacks: 1. High cost: Each tank requires independent procurement and installation of the drive motor, transmission components, and control system, leading to a significant increase in equipment investment costs, especially placing a substantial economic burden on small and medium-sized aquaculture enterprises. 2. Inconvenient maintenance: Multiple independent mixing structures require separate daily inspections and troubleshooting, which is time-consuming and labor-intensive, and the redundancy of components can increase the failure rate. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this utility model provides a simple fermentation device for aquatic microorganisms. This device can connect multiple tanks together and share a single drive mechanism, which can greatly reduce costs and facilitate maintenance, effectively solving the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a simple fermentation device for aquatic microorganisms, comprising several horizontally spaced tanks, each tank being spherical, with meshing gear discs fixed at the vertical maximum diameter of adjacent tanks, and horizontal rotating shafts fixed at the center of the left and right sides of the tanks, the rotating shafts being rotatably connected to bearings on a rectangular frame surrounding all the tanks, with support members spaced apart on the bottom surface of the rectangular frame, the bottom of the support members being fixed to a base plate, and the gear disc on the leftmost tank being connected to a drive mechanism on the left, the drive mechanism being fixed to the base plate;
[0006] The tank body on one side of the gear disk is provided with a filling port, and the filling port is threadedly sealed with a cap.
[0007] A pressure relief valve is also provided on the tank body on the sealed side.
[0008] As a preferred technical solution, baffles are also fixedly provided circumferentially at intervals inside the tank on the inner side of the gear disk.
[0009] As a preferred technical solution, the driving mechanism includes a gear that meshes with the leftmost gear disk, the gear is fixed to the drive motor, the drive motor is fixed to the fixing block on the base plate, and the bottom of the fixing block is fixed to the base plate.
[0010] As a preferred technical solution, the support includes an L-shaped support plate, the top surface of which is fixedly connected to the bottom surface of the rectangular frame, and the bottom horizontal portion of the L-shaped support plate is fixedly connected to the base plate by a first bolt.
[0011] As a preferred technical solution, the bottom of the front and rear sides of the fixing block is provided with horizontal plates, and the horizontal plates are fixedly connected to the base plate by the second bolts.
[0012] As a preferred technical solution, a cylindrical tube is connected to the center of the outer surface of the cover, and an end cap is threaded to the outer end of the cylindrical tube.
[0013] As a preferred technical solution, the bottom edge of the base plate is also provided with omnidirectional wheels that have a limiting function.
[0014] Compared with the prior art, this utility model provides a simple fermentation device for aquatic microorganisms, which has the following beneficial effects:
[0015] 1. This utility model features intermeshing gear discs fixed at the vertical maximum diameter of adjacent tanks. Horizontal rotating shafts are fixed at the center of the left and right sides of each tank, and these shafts are rotatably connected to bearings on the upper side of a rectangular frame surrounding all the tanks. Support members are spaced apart on the bottom surface of the rectangular frame, with their bottoms fixed to a base plate. The gear disc on the leftmost tank is connected to a drive mechanism on the left. In use, fermenting microorganisms can be stored inside the tanks. The drive mechanism on the left can simultaneously drive multiple tanks to rotate, thus achieving a stirring effect. This significantly reduces costs and facilitates maintenance. The rotating shafts and rectangular frame facilitate circumferential rotation of the tanks, and the rectangular frame provides a protective enclosure around all the tanks, preventing collisions with pedestrians or vehicles.
[0016] 2. This utility model has a filling port on one side of the tank body of the gear disk, and a sealing cap is connected to the filling port by a threaded seal. A pressure relief valve is also provided on the side of the tank body of the sealing cap. In use, the filling port facilitates the filling of bamboo material into the tank and the subsequent discharge of material.

[0017] 3. In this utility model, baffles are also fixedly installed circumferentially inside the tank on the inner side of the gear disk. When in use, three-quarters of the microorganisms can be stored in the tank. When the tank rotates, the baffles can turbulent the flow of microorganisms, which is beneficial to the stirring of microorganisms.
[0018] 4. This utility model has a cylindrical tube connected to the center of the outer surface of the cap. The outer end of the cylindrical tube is threaded with an end cap. In use, by controlling the drive mechanism to make the filling port of the tank face downward, the end cap can be opened to take out a small amount of microorganisms, which can be used for sampling.
[0019] 5. This utility model is equipped with universal wheels with limiting function at intervals along the bottom edge of the base plate. During use, the universal wheels can be used to easily move the tank to the required position, which facilitates filling and unloading, and improves the convenience of use.

Horizontal rotating shafts 14 are fixedly installed at the center of the left and right sides of each tank 1. The rotating shafts 14 are rotatably connected to bearings 31 (embedded in the left and right side plates of the rectangular frame) on a rectangular frame 3 surrounding all tanks 1. Support members are spaced apart on the bottom surface of the rectangular frame 3, with their bottoms fixed to a base plate 5. The gear disc 2 on the leftmost tank 1 is connected to a drive mechanism 6 on the left side, which is fixed to the base plate 5. A filling port 11 is provided on one side of the tank 1 containing the gear disc 2, and a sealing cap 12 is threadedly connected to the filling port 11 (the sealing caps 12 do not affect each other when the tanks 1 rotate). A pressure relief valve 13 is also provided on one side of the sealing cap 12.
[0029] Inside the tank 1 on the inner side of the gear disk 2, baffles 15 are also fixedly installed at intervals around the circumference (the outer side of the baffle 15 is perpendicular to the inner surface of the tank 1).
[0030] The drive mechanism 6 includes a gear 61 that meshes with the leftmost gear disk 2. The gear 61 is fixed to the drive motor 62, which is fixed to the fixing block 63 on the base plate. The bottom of the fixing block 63 is fixed to the base plate 5.

The filling port facilitates the filling of materials into the tanks 1 and subsequent discharge. The pressure relief valve 13 provides pressure relief, ensuring the safety of microbial fermentation. When three-quarters of the microorganisms are stored in the tank 1, the baffle 15 can turbulent the flow of microorganisms during rotation, promoting stirring. Example 2
