However, the jacketed structure causes the temperature of the fermentation liquid near the inner wall of the tank to change faster, while the temperature of the fermentation liquid near the middle changes relatively slowly, resulting in a temperature difference. Based on this, a microbial fermentation seed tank is provided. Utility Model Content

Detailed Implementation
[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Please see Figures 1-5 In this embodiment of the present invention, a microbial fermentation seed tank includes a fermentation tank 1 and a stirring assembly 2. A heat exchange assembly 3 is provided inside and outside the fermentation tank 1. The heat exchange assembly 3 is used to exchange heat with the fermentation liquid inside the fermentation tank 1.
[0032] Heat exchange component 3 includes a heat exchange unit and a linkage unit;
[0033] The channels formed by the heat exchange units are used to supply the flow of heat exchange medium, so as to achieve uniform heat exchange with the fermentation liquid inside the fermenter 1.
[0034] The linkage unit utilizes the driving force of the stirring component 2 to assist in multi-directional stirring inside the fermenter 1;
[0035] The heat exchange unit includes an annular tube 301, a heat exchange tube 302, a connecting tube 303, a protective sleeve 304, a rotating cylinder 305, a diversion tube 308, an inlet pipe 309, and an outlet pipe 310.
[0036] Annular pipes 301 are distributed on the outside of fermenter 1. Multiple heat exchange pipes 302 are provided, and multiple heat exchange pipes 302 are fixed on the inside of annular pipes 301 and penetrate into the interior of fermenter 1.
[0037] The protective casing 304 is distributed inside the fermenter 1 and the center of the protective casing 304 coincides with the center of the fermenter 1. Multiple heat exchange tubes 302 penetrate into the interior of the protective casing 304 and are fixedly connected to the connecting tube 303.
[0038] Multiple sets of annular tube 301, heat exchange tube 302, connecting tube 303, and protective sleeve 304 are evenly arranged vertically. Rotating cylinder 305 is rotatably connected between two protective sleeves 304 and penetrates into the interior of the protective sleeve 304 and is sleeved and connected to the connecting tube 303.
[0039] The outlet pipe 310 is connected to the bottommost annular pipe 301, the diversion pipe 308 is connected to multiple annular pipes 301 that are not at the bottom, and the inlet pipe 309 is fixed to the outside of the diversion pipe 308 and connected to the diversion pipe 308.
[0040] The channel consisting of inlet pipe 309, diversion pipe 308, annular pipe 301, heat exchange pipe 302, connecting pipe 303, rotating cylinder 305, and outlet pipe 310 is used to realize the circulation of heat exchange medium.
[0041] In this embodiment: When fermenting microbial seeds, the fermentation liquid inside the fermenter 1 is stirred by the stirring component 2. At the same time, the temperature of the fermentation liquid inside the fermenter 1 can be controlled by supplying a heat exchange medium into the heat exchange component 3. The flow trajectory of the heat exchange medium inside the heat exchange component 3 is as follows:
[0042] The heat exchange medium is transported to the distribution pipe 308 through the liquid inlet pipe 309 and then distributed into the interior of multiple annular pipes 301. After that, it flows into the interior of the connecting pipe 303 along multiple heat exchange tubes 302, and then flows downward along the vertical pipe formed by the rotating cylinder 305 and the connecting pipe 303 (it should be noted that: except for the bottom rotating cylinder 305, the other rotating cylinders 305 are all hollow structures and are open at both ends). Finally, it flows into the bottom heat exchange tube 302 through the bottom connecting pipe 303, and then flows to the liquid outlet pipe 309 through the bottom annular pipe 301 to be discharged. This process is repeated to achieve the circulation of the heat exchange medium.
[0043] During this process, the heat exchange medium flowing inside the heat exchange tube 302 and the rotating cylinder 305 can exchange heat with the fermentation liquid inside the fermenter 1, thereby achieving the effect of controlling the temperature of the fermentation liquid. Compared with the traditional structure that exchanges heat through the jacket structure of the fermenter 1, the heat exchange tube 302 and the rotating cylinder 305 are evenly distributed inside the fermenter 1, and the heat exchange with the fermentation liquid is more uniform and efficient.
[0044] Please refer to this carefully. Figures 1-5 The stirring assembly 2 includes a drive motor 201, a drive shaft 202, and a stirring blade 203;
[0045] The drive motor 201 is installed at the top center of the fermentation tank 1, the drive shaft 202 is fixed to the output end of the drive motor 201 and extends into the interior of the fermentation tank 1, and the stirring blades 203 are symmetrically fixed to the outside of the drive shaft 202.
[0046] The linkage unit includes a linkage bevel gear 306 and a transmission bevel gear 307;
[0047] The bottom end of the drive shaft 202 extends into the topmost protective sleeve 304. The linkage bevel gear 306 is distributed inside the protective sleeve 304 and is fixed to the bottom outer side of the drive shaft 202 and the upper and lower outer sides of the rotating cylinder 305, respectively.
[0048] The transmission bevel gears 307 are distributed inside the protective sleeve 304 and rotatably connected to the outside of the heat exchange tube 302. The transmission bevel gears 307 inside the topmost protective sleeve 304 mesh synchronously with the linkage bevel gears 306 on the drive shaft 202 and the rotating cylinder 305. The transmission bevel gears 307 inside the other protective sleeves 304 mesh synchronously with the linkage bevel gears 306 on the two rotating cylinders 305.
[0049] The transmission between the linkage bevel gear 306 and the drive bevel gear 307 is used to achieve synchronous and opposite rotation between the top rotating cylinder 305 and the drive motor 201, as well as between two adjacent rotating cylinders 305.
[0050] The bottom protective sleeve 304 is rotatably connected to a solid rotating cylinder 305, and all rotating cylinders 305 are fixed with stirring plates 203 on their outer sides.
[0051] In this embodiment: when the drive motor 201 is running, the drive motor 201 drives the drive shaft 202 to rotate. The drive shaft 202 can drive the top rotating cylinder 305 to rotate through the transmission of the linkage bevel gear 306 and the transmission bevel gear 307. The bottom of this rotating cylinder 305 drives the second rotating cylinder 305 to rotate through the linkage bevel gear 306 and the transmission bevel gear 307. By repeating this transmission, all the rotating cylinders 305 can be rotated.
[0052] Furthermore, the rotation directions of two adjacent rotating cylinders 305 are opposite, and the rotation direction of the top rotating cylinder 305 is opposite to the rotation direction of the drive shaft 202. In this way, the drive shaft 202 and the rotating cylinders 305 drive their respective stirring plates 203 to rotate in different directions, which can realize the multi-directional stirring operation of the fermentation liquid, further improve the mixing efficiency of the fermentation liquid, and thus improve the fermentation efficiency.
[0053] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
