[0002] Microbial fermentation is a process of using microorganisms to carry out metabolic activities under specific conditions to convert chemical raw materials into required products. In the production of chemical products, many organic compounds, bioactive substances, etc. can be synthesized through microbial fermentation.

[0003] When the existing fermenter ferments chemical products, the raw materials inside are stirred and mixed by a stirring rod. However, the mixing method relying solely on the stirring rod is relatively inefficient. At the same time, when carrying out chemical preparation, the chemical raw materials need to obtain an appropriate amount of oxygen to maintain the best fermentation conditions. Therefore, a multi-stage continuous fermenter for chemical product preparation is proposed. Content of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a multi-stage continuous fermenter for chemical product preparation to solve the technical problems raised in the above background.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0023] Next, according to the overall structure of the present utility model, its embodiments will be described.

[0024] A multi-stage continuous fermentation tank for preparing chemical products, as Figures 1-5 shown, includes a fermentation tank 100. A mixing assembly 200 is provided inside the fermentation tank 100, and a feeding assembly 300 is provided on one side of the top end of the fermentation tank 100. The mixing assembly 200 includes a first servo motor 210 fixedly connected to the top end of the fermentation tank 100. The output end of the first servo motor 210 is fixedly connected with an auger 220. The surface of the auger 220 is rotatably connected with a sleeve 230, and the bottom end of the auger 220 is fixedly connected with a gear a 240. Gears b 250 meshing with each other are provided on both sides of the gear a 240. The center of the gear b 250 is fixedly connected with a reciprocating screw rod 260. The surface of the reciprocating screw rod 260 is rotationally connected with a semi-circular disk 270.

[0025] By starting the first servo motor 210, the auger 220 is driven to rotate. Through the interaction between the auger 220 and the sleeve 230, the chemical raw materials inside the fermenter 100 can be continuously conveyed upward, causing the conveyed chemical raw materials to gush out from the top of the sleeve 230 and then flow back into the fermenter 100 again. Thus, the microorganisms and the chemical raw materials can be fully contacted and mixed, promoting the full reaction between the bacterial strains and the chemical raw materials. At the same time, by conveying the chemical raw materials upward, it can ensure that each layer obtains an appropriate amount of materials and oxygen, thereby maintaining the optimal fermentation conditions. While the auger 220 rotates, it drives the gear a 240 to rotate, and the gear a 240 drives the gear b 250 to rotate synchronously, causing the gear b 250 to drive the reciprocating lead screw 260 to rotate. The reciprocating lead screw 260 drives the semi - disk 270 to reciprocate up and down inside the fermenter 100, tumbling the chemical raw materials reciprocally, further enhancing the mixing efficiency of the chemical raw materials, and thus increasing the fermentation rate.

[0026] Please refer specifically to Figure 1 and Figure 3 At the lower end of the surface of the fermenter 100, a support plate 110 is welded, and at the bottom end of the fermenter 100, a discharge pipe 120 is provided. An electromagnetic valve 121 is installed on the discharge pipe 120. On one side of the surface of the sleeve 230, a cross - plate 232 is welded, and the end of the cross - plate 232 far from the sleeve 230 is fixedly connected to the inner wall of the fermenter 100.

[0027] The stability of the fermenter 100 can be enhanced through the support plate 110, and the sleeve 230 can be fixed by setting the cross - plate 232.

[0028] Please refer specifically to Figure 2 and Figure 3 At the bottom end of the reciprocating lead screw 260, a limiting shaft 261 is fixedly connected, and the limiting shaft 261 is rotatably connected to the bottom end inner wall of the fermenter 100. On one side of the semi - disk 270, a limiting block 271 is welded, and on both sides of the surface of the sleeve 230, sliding grooves 231 that fit the limiting block 271 are opened.

[0029] By setting the limiting shaft 261, the reciprocating lead screw 260 can be prevented from moving. Through the mutual cooperation between the limiting block 271 and the sliding groove 231, the semi - disk 270 can be effectively prevented from rotating.

[0030] Please refer specifically to Figure 1 、 Figure 4 and Figure 5, the feeding assembly 300 includes a storage cylinder 310 fixedly connected to one side of the top end of the fermentation tank 100. A second servo motor 320 is fixedly connected to the top end of the storage cylinder 310. The output end of the second servo motor 320 is welded with a fixed shaft 330. A fixed disk 340 is attached to the bottom end of the fixed shaft 330. A rotating plate 350 welded to the surface of the fixed shaft 330 is provided at the top end of the fixed disk 340. A stopper 360 is attached to the top end of the rotating plate 350. A feeding pipe 370 is connected to one side of the storage cylinder 310, and a vertical pipe 380 is connected to the bottom end of the storage cylinder 310. The fixed disk 340, the stopper 360 and the inner wall of the storage cylinder 310 are fixedly connected. A groove 341 is formed inside the fixed disk 340, and a storage groove 351 is formed inside the rotating plate 350.

[0031] By starting the second servo motor 320 to drive the fixed shaft 330 to rotate, the fixed shaft 330 drives the rotating plate 350 to rotate. When the storage groove 351 inside the rotating plate 350 fits with the stopper 360, the top end of the storage groove 351 is closed. The rotating plate 350 continues to rotate. When the storage groove 351 coincides with the groove 341, the chemical raw materials inside the storage groove 351 will enter the vertical pipe 380 from the groove 341 and finally enter the fermentation tank 100, thereby realizing the effect of quantitative and continuous addition of chemical raw materials. The multi-stage continuous addition can make the fermentation tank 100 have higher production efficiency and stability, reduce the differences and wastes between batches, and the product yield and purity can be optimized by adjusting the fermentation conditions.

[0032] During use, by starting the first servo motor 210, the auger 220 is driven to rotate. Through the interaction between the auger 220 and the sleeve 230, the chemical raw materials inside the fermentation tank 100 can be continuously conveyed upward, so that the conveyed chemical raw materials gush out from the top of the sleeve 230 and then flow back into the fermentation tank 100 again, thereby enabling the microorganisms to fully contact and mix with the chemical raw materials, promoting the full reaction between the bacterial strain and the chemical raw materials. At the same time, by conveying the chemical raw materials upward, it can ensure that each layer obtains an appropriate amount of materials and oxygen, so as to maintain the best fermentation conditions. While the auger 220 rotates, it drives the gear a 240 to rotate, so that the semi-circular disk 270 reciprocates up and down inside the fermentation tank 100, tumbling the chemical raw materials reciprocally, further enhancing the mixing efficiency of the chemical raw materials, thereby improving the fermentation rate. By starting the second servo motor 320 to drive the fixed shaft 330 to rotate, the effect of quantitative and continuous addition of chemical raw materials is realized. The multi-stage continuous addition can make the fermentation tank 100 have higher production efficiency and stability, reduce the differences and wastes between batches, and the product yield and purity can be optimized by adjusting the fermentation conditions. The parts not involved in this device are the same as or can be implemented by using the prior art.

The specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can make modifications, substitutions, and variations that do not make creative contributions to the embodiments as needed, but as long as they are within the scope of the claims of the present utility model, they are protected by the patent law.
