Abstract
Description
Technical Field
[0001] This utility model relates to the field of fermentation technology, and in particular to a fermentation device for fermentation broth. Background Technology
[0002] The production of bio-enzymes requires steps such as raw material cultivation, raw material fermentation, and bio-enzyme extraction. Since the raw material fermentation step is time-consuming, a special fermentation tank is required during the fermentation process. During fermentation, the raw materials need to be stirred to ensure that they react fully. Stirring not only prevents the solid raw materials from settling at the bottom for a long time, but also improves the overall mixing uniformity of the materials, so that the components in the raw materials can fully contact and react.
[0003] The fermentation device for facilitating stirring of fermentation broth, as described in announcement number CN219342124U, includes a fermentation tank. A stirring assembly is rotatably installed inside the fermentation tank. The stirring assembly includes a central column, and several layers of side plates arranged in a linear array in the vertical direction are fixedly connected to the outer side of the central column. Each layer includes several side plates arranged in a ring array. A drive motor is bolted to the top of the fermentation tank. The output shaft of the drive motor passes through the top cover of the fermentation tank and is connected to the stirring assembly for transmission and rotation. A conveying pipe is provided on the outer side of the fermentation tank, and the outlet of the conveying pipe at the top passes through the side wall of the fermentation tank.
[0004] Based on the above technical features, the problem is that existing stirring devices tend to cause the mixture to form a relatively fixed flow direction during the stirring process, resulting in uneven mixing, uneven fermentation, and ultimately affecting the fermentation quality.
[0005] Therefore, it is necessary to solve the above problems by using a fermentation device for fermentation broth. Utility Model Content

[0008] Preferably, the turbulent production component includes multiple transmission blocks and multiple rotating plates; the multiple rotating plates correspond one-to-one with multiple stirring plates, and each rotating plate is rotatably connected to the end of the corresponding stirring plate away from the rotating shaft; a torsion spring is fixedly installed at the connection between each rotating plate and the corresponding stirring plate; the multiple transmission blocks are fixed on the inner wall of the fermenter; the multiple transmission blocks correspond one-to-one with multiple rotating plates, and each rotating plate abuts and drives the corresponding transmission block.
[0009] Preferably, the liquid circulation mechanism includes a water pump and a U-shaped circulation pipe; both ends of the circulation pipe are fixedly connected to the fermentation tank, and the two ends are arranged symmetrically, one above the other; the water pump is fixedly installed at the lower end of the circulation pipe.
[0010] Preferably, multiple three-bladed plates are rotatably installed inside the circulation pipe, and the rotation axis of each three-bladed plate is collinear with the central axis of the circulation pipe.

[0012] Preferably, each stirring plate and each rotating plate has through holes.
[0013] The technical effects and advantages of this utility model are as follows: During the mixing of the fermentation liquid by the stirring plate, the turbulent production component of this utility model causes the fermentation liquid to become turbulent and the liquid flow direction to become chaotic; at the same time, the liquid circulation mechanism draws the fermentation liquid out of the fermentation tank and puts it back in, thereby causing the liquid to become mixed again; after two mixing processes, the materials are mixed evenly, ensuring the fermentation quality of the fermentation liquid.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0019] This utility model provides, for example Figures 1 to 3 A fermentation apparatus for fermentation broth is shown, comprising a fermenter 2, which is vertically fixedly mounted on a support 1. The top of the fermenter 2 is fixedly connected to a feed pipe 3, and the bottom of the fermenter 2 is fixedly connected to a discharge pipe 10. Control valves are installed in both the feed pipe 3 and the discharge pipe 10.
[0020] A rotating shaft 5 is vertically placed inside the fermentation tank 2, and a motor 4 is fixedly installed on the top of the fermentation tank 2. The output shaft of the motor 4 is coaxially and fixedly connected to the rotating shaft 5.
[0021] Multiple stirring plates 6 are welded and fixed on the rotating shaft 5. The multiple stirring plates 6 are evenly distributed on the rotating shaft 5, and each stirring plate 6 is arranged radially along the rotating shaft 5.
[0022] A turbulence generator is installed inside the fermenter 2, and the turbulence generator is driven by multiple stirring plates 6.
[0023] The turbulent production component includes multiple transmission blocks 9 and multiple rotating plates 8. Each rotating plate 8 corresponds to a stirring plate 6, and each rotating plate 8 is rotatably connected to the end of the corresponding stirring plate 6 away from the rotating shaft 5.
[0024] A connecting shaft is inserted at the connection point between each rotating plate 8 and its corresponding stirring plate 6, passing vertically through both the rotating plate 8 and the stirring plate 6. The stirring plate 6 is fixedly connected to the connecting shaft, while the rotating plate 8 is rotatably connected to the connecting shaft. A torsion spring is fitted onto the connecting shaft, with one end of the torsion spring fixedly connected to the rotating plate 8 and the other end fixedly connected to the stirring plate 6.
[0025] Multiple transmission blocks 9 are fixed on the inner wall of the fermenter 2. Each transmission block 9 corresponds to a multiple rotating plate 8, and each rotating plate 8 engages with the corresponding transmission block 9 in a transmission-prone manner when in contact.
[0026] Each stirring plate 6 and each rotating plate 8 has a through hole 7.
[0027] Fermentation tank 2 is equipped with a liquid circulation mechanism for pumping out liquid.
[0028] The liquid circulation mechanism includes a water pump 12 and a U-shaped circulation pipe 11. Both ports of the circulation pipe 11 are fixedly connected to the fermentation tank 2, and the two ports are symmetrically arranged, one above the other. The water pump 12 is fixedly installed at the lower port of the circulation pipe 11, which is used to draw the fermentation liquid out of the fermentation tank 2 from the bottom and put it back in from the top.
[0029] Multiple mounting seats are fixedly installed inside the circulation pipe 11. The mounting seats are evenly distributed along the axial direction of the circulation pipe 11, and a three-bladed plate 13 is rotatably mounted on each mounting seat. Each three-bladed plate 13 is a three-bladed fan, and the rotation axis of each three-bladed plate 13 is collinear with the central axis of the circulation pipe 11.
[0030] Working principle: When producing fermentation broth, motor 4 and water pump 12 are started. The output shaft of motor 4 drives the rotating shaft 5 to rotate, and the rotating shaft 5 drives all the stirring plates 6 to stir the fermentation broth. As the stirring plates 6 rotate with the rotating shaft 5, the stirring plates 6 drive the connected rotating plates 8 to revolve around the rotating shaft 5 through the connecting shaft.
[0031] When the rotating plate 8 revolves around the rotating shaft 5, it comes into rotational contact with the corresponding transmission block 9. After contact, the transmission block 9 pushes the rotating plate 8 to rotate around the connecting shaft. As the rotating plate 8 rotates, the torsion spring twists, creating turbulence between the rotating plate 8 and the stirring plate 6, thus disrupting the flow direction of the fermentation broth. After the rotating plate 8 disengages from the transmission block 9, under the action of the torsion spring, the rotating plate 8 reverses direction, thereby generating turbulence again at the end of the rotating plate 8 away from the stirring plate 6.
[0032] At the same time, during the stirring process, the fermentation liquid impacts the transmission block 9, which once again disrupts the flow direction of the fermentation liquid.
[0033] When water pump 12 is working, it draws the fermentation liquid from fermenter 2 into circulation pipe 11. The fermentation liquid in circulation pipe 11 flows from the lower inlet to the upper inlet, and finally flows back into fermenter 2 from the upper inlet. During this process, the fermentation liquid in circulation pipe 11 impacts and rotates the tri-blade 13, which agitates and stirs the liquid. Simultaneously, the fermentation liquid in fermenter 2 undergoes alternating up-and-down flow, further disrupting the flow direction and resulting in more uniform mixing.
[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
