Description

Technical Field

[0001] This utility model relates to the field of experimental equipment technology, and in particular to an experimental fermenter. Background Technology

[0002] Biology, or simply biology, is one of the six fundamental disciplines of natural science. Taxonomy is a branch of biology that studies the methods and principles of biological classification. Fermentation tanks are frequently used in biological experiments. A fermentation tank is an industrial device used for microbial fermentation. Its main body is generally a cylindrical structure made of stainless steel, with a volume ranging from 1 m³ to several hundred m³. Careful attention should be paid to its structural integrity and rational design during manufacturing.

[0003] Chinese utility model patent CN208430175U discloses a bioreactor that is easy to heat. By setting up a U-shaped base, an electric heating wire and a circuit controller, it can not only control the circuit in the heating device in real time, but also has a good heat preservation effect, high heat utilization efficiency, and heat recovery function, thus reducing heat waste.

[0004] Regarding the aforementioned related technologies, the inventors believe that the following defects exist: When the device heats the inside of the tank, the heating position is relatively fixed, resulting in local overheating inside the tank. This causes the heat in that part to be higher than that in other parts, resulting in uneven heating inside the tank, which affects the distribution of microorganisms and thus the uniformity of fermentation. Therefore, we propose an experimental fermenter. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides an experimental fermenter.

[0006] This utility model is achieved by the following technical solution: an experimental fermenter, including a connecting frame, with casters installed at the four corners of the bottom of the connecting frame, a tank body installed inside the connecting frame, a pressure relief valve installed on the top of the tank body, a heating groove opened inside the tank body, a lifting component installed inside the heating groove, and a stirring component installed inside the tank body.

[0007] The lifting assembly includes a drive motor, an active helical gear fixedly connected to the output end of the drive motor, a driven helical gear meshing with the surface of the active helical gear, a long rod penetrating through the shaft of the driven helical gear, two cams sleeved on the surface of the long rod, a lifting frame abutting the surface of the cams, a lifting rod fixedly connected to the bottom of the lifting frame, and a heating element fixedly connected to the bottom end of the lifting rod.

[0008] The stirring assembly includes a stirring rod, with a fixed plate rotatably connected to the bottom end of the stirring rod. The two ends of the fixed plate are respectively fixedly connected to the inner wall of the tank. The surface of the stirring rod and the surface of the output shaft of the drive motor are connected by two meshing connecting gears. A fixed rod is provided inside the stirring rod, with the bottom end of the fixed rod fixedly connected to the top of the fixed plate. Helical gears A are sleeved at equal intervals on the surface of the fixed rod. Two helical gears B are meshed on the surface of helical gears A. A crossbar is fixedly connected to the axis of helical gears B. Support rods are fixedly connected at equal intervals on the surface of the crossbar.

[0009] As a further improvement to the above solution, the top of the tank is connected to an inlet pipe, and the bottom of the tank is connected to an outlet pipe. Valves are installed on the outside of both the inlet and outlet pipes to facilitate control of the material's entry and exit.

[0010] As a further improvement to the above solution, a power supply is installed on the top of the tank. The power supply is connected to the left lifting rod through a line. The lifting rod is an insulated hollow rod, which ensures the safety of the device.

[0011] As a further improvement to the above solution, the heating component includes multiple heating tubes, with two mounting rings sleeved on the surface of each heating tube. Adjacent mounting rings are connected by connecting pipes, and the top of the top mounting ring is fixedly connected to the bottom of the lifting rod, facilitating the entire heating component to provide heat.

[0012] As a further improvement to the above solution, a protective cover is installed on the top of the tank, and the drive motor and connecting gear are installed inside the protective cover. The top of the fixing rod is fixedly connected to the top of the inner wall of the protective cover, ensuring the normal operation of the drive motor, connecting gear and fixing rod.

[0013] As a further improvement to the above solution, two seated bearings are installed on the surface of the long rod, and the bottom of the seated bearings is fixedly connected to the top of the protective cover to ensure the normal rotation of the long rod.

[0014] As a further improvement to the above solution, a small bearing is installed on the surface of the crossbar, and the small bearing is installed on the inner wall of the stirring rod to ensure the normal rotation of the crossbar.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention, by incorporating a lifting assembly, allows for the heating of the tank's interior when heating is required. Power is activated, initiating the heating element's operation. The drive motor, carrying the active helical gear, rotates, causing the driven helical gear to rotate the long rod. This continuous rotation of the cam strikes the inner wall of the lifting frame, causing the lifting frame and lifting rod to move vertically. This vertical movement of the heating element prevents localized overheating and ensures a more uniform heat distribution within the tank, reducing the risk of uneven microbial distribution due to uneven heat distribution.

[0017] This invention incorporates a stirring assembly. When the drive motor is operating, its output shaft rotates, causing the stirring rod to rotate under the action of two connecting gears. Consequently, the crossbar rotates along with the stirring rod. During this process, the fixing rod remains stationary, preventing the helical gear A from being fixed in place. As the helical gear B rotates along with the stirring rod, it is also engaged by the helical gear A, causing the helical gear B to rotate vertically. This process uniformly mixes and stirs microorganisms at different height levels within the tank, improving the uniformity of microbial distribution within the device. Attached Figure Description

[0025] Please combine Figure 1-4 An experimental fermenter according to this embodiment includes a connecting frame 1, with casters installed at the four corners of the bottom of the connecting frame 1. A tank body 2 is installed inside the connecting frame 1. A feed pipe is connected to the top of the tank body 2, and a discharge pipe is connected to the bottom of the tank body 2. Valves are installed on the outside of both the feed pipe and the discharge pipe to facilitate control of the material's entry and exit. A pressure relief valve is installed on the top of the tank body 2. A heating tank is opened inside the tank body 2, and a lifting assembly is installed inside the heating tank. A stirring assembly is installed inside the tank body 2.

[0026] The lifting assembly is used to uniformly provide heat to the tank 2. The lifting assembly includes a drive motor, and the output end of the drive motor is fixedly connected to a driving helical gear 3. The surface of the driving helical gear 3 is meshed with a driven helical gear 4. A long rod 5 is connected through the shaft of the driven helical gear 4. Two seated bearings are installed on the surface of the long rod 5. The bottom of the seated bearings is fixedly connected to the top of the protective cover to ensure the normal rotation of the long rod 5. Two cams 6 are sleeved on the surface of the long rod 5. The surface of the cams 6 abuts against a lifting frame 7. A lifting rod 8 is fixedly connected to the bottom of the lifting frame 7. A power supply is installed on the top of the tank 2. The power supply is connected to the left lifting rod 8 through a line. The lifting rod 8 is an insulated hollow rod to ensure the safety of the device. A heating element 9 is fixedly connected to the bottom of the lifting rod 8. The heating element 9 includes multiple heating tubes. Two mounting rings are sleeved on the surface of the heating tubes. Adjacent mounting rings are connected by connecting pipes. The top of the top mounting ring is fixedly connected to the bottom of the lifting rod 8 to facilitate the entire heating element 9 to provide heat.

[0027] The stirring assembly is used to evenly distribute microorganisms. The assembly includes a stirring rod 10, with a fixing plate 11 rotatably connected to the bottom end of the stirring rod 10. Both ends of the fixing plate 11 are fixedly connected to the inner wall of the tank body 2. The surface of the stirring rod 10 and the surface of the drive motor output shaft are connected by two meshing connecting gears 12. A fixing rod 13 is installed inside the stirring rod 10. A protective cover is installed on the top of the tank body 2. The drive motor and connecting gears 12 are both installed inside the protective cover. The top end of the fixing rod 13 is fixedly connected to the protective cover. The top of the inner wall ensures the normal operation of the drive motor, connecting gear 12 and fixing rod 13. The bottom end of the fixing rod 13 is fixedly connected to the top of the fixing plate 11. Helical gears A14 are sleeved at equal intervals on the surface of the fixing rod 13. Two helical gears B15 are meshed on the surface of the helical gears A14. A crossbar 16 is fixedly connected at the shaft of the helical gears B15. Small bearings are installed on the surface of the crossbar 16. The small bearings are installed on the inner wall of the stirring rod 10 to ensure the normal rotation of the crossbar 16. Support rods are fixedly connected at equal intervals on the surface of the crossbar 16.

[0028] The implementation principle of an experimental fermenter in this application embodiment is as follows: the material is introduced into the interior of the tank 2 through the feed pipe, and the valve at the feed pipe is closed so that the entire tank 2 is in a closed state. When it is necessary to control the pressure inside the tank 2, the pressure inside the tank 2 is adjusted through the pressure relief valve.

[0029] When it is necessary to heat the inside of the tank 2, the power is turned on, so that the entire heating component 9 begins to provide heat. Then the drive motor is started, so that the drive motor drives the active helical gear 3 to rotate, so that the driven helical gear 4 drives the long rod 5 to rotate, which in turn causes the cam 6 to rotate continuously and continuously strike the inner wall of the lifting frame 7, so that the lifting frame 7 and the lifting rod 8 move up and down in the vertical direction, which in turn causes the heating component 9 to move up and down in the vertical direction. This avoids local overheating and makes the heat distribution on the inner wall of the tank 2 more uniform, reducing the uneven distribution of microorganisms caused by uneven heat distribution.

[0030] When the drive motor is working, the output shaft of the drive motor rotates, and under the action of the two connecting gears 12, the stirring rod 10 rotates, which in turn causes the crossbar 16 to rotate together with the stirring rod 10. During this process, the fixing rod 13 remains fixed, so the helical gear A14 cannot be fixed. As the helical gear B15 rotates together with the stirring rod 10, it is also subjected to the meshing action of the helical gear A14, causing the helical gear B15 to rotate in the vertical direction. This uniformly mixes and stirs the microorganisms at different height levels in the tank 2, improving the uniformity of the distribution of microorganisms in the device.

[0031] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
