Description

Technical Field

[0001] This utility model belongs to the field of fermenter heating technology, specifically relating to a heating device for fermenters. Background Technology

[0002] A fermenter is a device for the growth, reproduction, and formation of the external environment for the product during the fermentation process. Temperature, pressure, and airflow need to be controlled during the fermentation process.

[0003] During the fermentation process, the fermentation tank needs to stir the materials, especially the liquid matrix materials. The liquid matrix materials will move axially during the stirring process. As we all know, the outer wall and bottom of the existing fermentation tank are equipped with heating structures to heat the liquid matrix materials in the fermentation tank.

[0004] Because the trajectory of the liquid matrix material is relatively fixed during the stirring and flow process, the outer and bottom parts of the liquid matrix material are effectively heated, while the middle part of the liquid matrix material, especially the outer part near the stirring shaft, is difficult to contact with heat, resulting in slow heating and making it difficult to heat the liquid matrix material evenly and efficiently.

[0005] Therefore, a heating device for fermenters is proposed. Summary of the Invention

[0006] This invention provides a heating device for fermenters, the purpose of which is to solve the problems mentioned above.

[0007] This utility model provides a heating device for a fermenter, including a fermenter body, a sealing cover, and a fermenter tank body, with the sealing cover located between the fermenter body and the fermenter tank body; a heating assembly disposed on the fermenter body and the sealing cover; wherein the heating assembly includes: an insulation sleeve fixed to the outer wall of the fermenter body; a vertical heating rod embedded and fixed inside the fermenter body; an electric push rod fixed to the bottom of the fermenter body by bolts; a lifting extrusion plate fixed to the output end of the electric push rod; a horizontal heating rod embedded and fixed inside the lifting extrusion plate; a discharge pipe welded to the center of the bottom of the lifting extrusion plate; a discharge solenoid valve embedded and fixed to the bottom of the sealing cover; a one-way valve fixed to the top of the sealing cover by screws; and a material guiding assembly disposed on the sealing cover and the fermenter tank body; wherein the material guiding assembly includes: a stirring shaft sleeve rotating at the center of the top of the sealing cover; a flow groove and a blade through groove opened on the outer wall of the stirring shaft sleeve, the flow groove being located on one side of the blade through groove.

[0008] A heating device for a fermenter, wherein the material guiding assembly further includes: a motor fixed to the center of the top of the fermenter body by bolts; a stirring shaft fixed to the output end of the motor; a flow channel two formed on the outer wall of the stirring shaft; and a blade fixed to the outer wall of the stirring shaft near the flow channel two; flanges welded to the bottom of the fermenter body and the top of the sealing cover respectively; and a support leg fixed to the bottom of the fermenter body by bolts.

[0009] Furthermore, the outer wall of the lifting extrusion plate is precisely fitted with the inner wall of the fermentation tank body, and the lifting extrusion plate performs piston-like movements inside the fermentation tank body;

[0010] By adopting the above technical solution, the precise piston movement can ensure the sealing of the lifting and pressing plate's movement inside the fermentation tank, effectively preventing leakage.

[0011] Furthermore, a valve is installed at the bottom of the discharge pipe, and the discharge pipe passes through the bottom of the fermentation tank body;

[0012] By adopting the above technical solution, the discharge pipe can be controlled by a valve, and the through-type structure can be used to ensure the normal lifting and lowering movement of the lifting extrusion plate.

[0013] Furthermore, a through hole is provided at the bottom of the sealing cap near the one-way valve, and the one-way valve is oriented towards the fermenter body;

[0014] By adopting the above technical solution, it is ensured that the liquid matrix material in the fermenter flows into the fermenter body in one direction after passing through the one-way valve.

[0015] Furthermore, a check valve is provided at the bottom of the sealing cap, directly below the stirring shaft sleeve;

[0016] By adopting the above technical solution, the backflow of liquid matrix material into the stirring shaft sleeve is avoided.

[0017] Furthermore, the blade passes through the blade penetration groove;

[0018] By adopting the above technical solution, it is easy to install the blades, and by using the limiting function of the blade through groove, the stirring shaft sleeve can rotate synchronously when the stirring shaft rotates.

[0019] Furthermore, the stirring shaft adopts a hollow tubular structure, and the second flow channel coincides with the first flow channel;

[0020] By adopting the above technical solution, the liquid matrix material in the fermenter can pass through the first and second flow channels and enter the stirring shaft, and then pass through the sealing cover into the fermenter body.

[0021] The beneficial effects of this utility model are as follows:

[0022] This invention utilizes a unidirectional flow channel for the liquid matrix material formed by the combination of a stirring shaft sleeve and a stirring shaft. This ensures that while the stirring operation is carried out normally inside the fermenter, the liquid matrix material with a relatively inner flow trajectory in the middle of the fermenter body can enter the fermenter body. The heating structure of the fermenter body is used to rapidly heat the liquid matrix material. By repeatedly performing the pumping and squeezing operations of the liquid matrix material, the liquid matrix material in the middle position inside the fermenter body can be effectively heated, ensuring uniform heating and high heating efficiency of the entire fermenter.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0032] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 This utility model provides a heating device for a fermenter, including a fermenter body 1. A sealing cover 2 is fixedly installed on the top of the fermenter body 1. A fermenter tank body 3 is installed above the sealing cover 2. An insulation sleeve 41 of a heating component 4 is installed on the outer wall of the fermenter body 1. A vertical heating rod 42 is embedded and fixed in the wall thickness of the fermenter body 1. Two electric push rods 43 are symmetrically fixed to the bottom of the fermenter body 1 by bolts. A lifting and pressing plate 44 is fixedly connected to the output end of the two electric push rods 43. The outer wall of the lifting and pressing plate 44 is precisely fitted with the inner wall of the fermenter body 1. The lifting and pressing plate 44 performs piston-like movement inside the fermenter body 1. The precise piston-like movement ensures the sealing of the lifting and pressing plate 44's movement inside the fermenter body 1, effectively preventing leakage. A horizontal heating rod 45 is embedded and fixed inside the lifting and pressing plate 44. A discharge pipe 5 is welded to the center of the bottom of the lifting and pressing plate 44. The bottom end of the discharge pipe 5 is provided with... A valve is installed, and the discharge pipe 5 passes through the bottom of the fermenter body 1. The valve controls the discharge of material from the discharge pipe 5, and the through structure ensures the normal lifting and lowering movement of the lifting extrusion plate 44. A discharge solenoid valve 6 is embedded and fixed at the bottom of the sealing cover 2, and a one-way valve 7 is fixed to the top of the sealing cover 2 by screws. A through hole is opened at the bottom of the sealing cover 2 near the one-way valve 7. The one-way nature of the one-way valve 7 faces the fermenter body 3, ensuring that the liquid matrix material in the fermenter body 1 passes through the one-way valve. The liquid phase matrix material flows into the fermenter body 3 in a one-way manner after 7. The top center of the sealing cover 2 is rotatably connected to the stirring shaft sleeve 81 in the material guiding assembly 8. A check valve is set at the bottom of the sealing cover 2 near the stirring shaft sleeve 81 to prevent the liquid phase matrix material from flowing back to the stirring shaft sleeve 81 and to ensure that the liquid phase matrix material in the stirring shaft sleeve 81 flows into the fermenter body 1 in a one-way manner. A flow groove 82 and a blade through groove 83 are opened on the outer wall of the stirring shaft sleeve 81. The flow groove 82 is located on one side of the blade through groove 83.

[0033] The specific implementation method is as follows: When heating the liquid matrix material in the fermenter, the liquid matrix material is stirred inside the fermenter body 3. When the electric push rod 43 moves downward through its output end, a negative pressure environment is formed inside the fermenter body 1. Under the action of negative pressure, the liquid matrix material in the middle part of the fermenter body 3 near the outside of the stirring shaft sleeve 81 passes through the flow channel 82 and the check valve and enters the fermenter body 1. The heat generated by the vertical heating rod 42 and the horizontal heating rod 45 is energized to heat the liquid matrix material. After a certain period of time, the liquid matrix material is heated by an external PLC controller. The electric push rod 43 drives the lifting extrusion plate 44 to move upward through its output end on one side. The lifting extrusion plate 44 pushes the liquid matrix material upward inside the fermenter body 1. Since the fermenter body 1 and the sealing cover 2 form a relatively sealed space, as the lifting extrusion plate 44 continues to move upward, the liquid matrix material, after being subjected to increased extrusion pressure, flows into the fermenter body 3 from the one-way valve 7. By repeatedly heating part of the liquid matrix material, the liquid matrix material in the middle position inside the fermenter body 3 can be heated, ensuring uniform heating and heating efficiency.

[0034] In a further preferred embodiment of this utility model, such as Figure 1 and Figure 4 As shown, a motor 84 is bolted to the center of the top of the fermentation tank body 3. A stirring shaft 85 is fixedly connected to the motor 84 through its output end on one side. A second flow channel 86 is provided on the outer wall of the stirring shaft 85. The stirring shaft 85 adopts a hollow tubular structure. The second flow channel 86 and the first flow channel 82 overlap, allowing the liquid matrix material in the fermentation tank body 3 to pass through the first flow channel 82 and the second flow channel 86 and enter the stirring shaft 85, and then pass through the sealing cover 2 and enter the fermentation tank body 1. A blade 87 is fixedly installed on the outer wall of the stirring shaft 85 near the second flow channel 86. The blade 87 passes through the blade penetration groove 83. Flanges 9 are welded to the top of the sealing cover 2 and the bottom of the fermentation tank body 3. The two flanges 9 are fixedly connected by bolts. Three support legs 10 are fixedly installed at equal intervals along the axis at the bottom of the fermentation tank body 1.

[0035] The specific implementation method is as follows: When the stirring shaft 85 and the stirring shaft sleeve 81 are connected, the stirring shaft 85 is inserted into the stirring shaft sleeve 81, and the blade 87 is fixed on the stirring shaft 85 after passing through the blade through groove 83. At this time, the first flow groove 82 and the second flow groove 86 overlap. When the motor 84 drives the stirring shaft 85 to rotate through its output end on one side, the stirring shaft sleeve 81 rotates synchronously. By utilizing the flow channel formed by the stirring shaft 85 and the stirring shaft sleeve 81, the liquid phase matrix material in the middle position inside the fermenter body 3 can gradually enter the fermenter body 1.
