Description

Technical Field

[0001] The utility model relates to the technical field of fermentation equipment, in particular to a motor mounting base and a vertical stirring fermentation tank. Background Art

[0002] A fermentation tank is an industrial device used for microbial fermentation. Its main body is generally a cylindrical cylinder made of stainless steel plates, with a volume ranging from one cubic meter to several hundred cubic meters.

[0003] There is a stirring device inside the tank, which is used for continuous stirring during the fermentation process. The power of the stirring device is generally provided by a drive motor. In the vertical installation method, the motor is installed on the axis of the tank and is located on the top of the fermentation tank, and the output shaft of the motor extends into the tank from the top of the tank.

[0004] The motor will vibrate violently during operation, which will cause the fermentation tank body to vibrate, which is not conducive to the fermentation process of microorganisms. Therefore, it is very important to improve the stability of the motor and prevent its vibration from affecting the fermentation tank. The existing fixing methods mainly include screw fixing or fixing with multiple reinforcing ribs. However, during the production process of the fermentation tank, the combined effects of the pressure and temperature changes in the fermentation tank, the weight of the motor itself, and the self-weight of the fermentation tank stirring shaft may cause a certain degree of deformation of the tank top, and the fermentation tank is mostly made of stainless steel, which is not as strong as iron reinforcement ribs. Therefore, when vibrating for a long time, the rigid connection between the existing fixing method and the tank top is prone to fatigue damage when the tank top is deformed, causing damage to the tank top. Summary of the Invention

[0005] In response to the above technical problems, the utility model provides a motor mounting base and a vertical stirring fermentation tank. The base can serve as a transition connection component between the motor and the fermentation tank. The base can disperse the force transmitted when the fermentation tank body is deformed by increasing the contact area with the fermentation tank in the connection structure with the fermentation tank, thereby avoiding damage to the tank top and having the advantage of high connection stability.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A motor mounting base is provided, the base being cylindrical and comprising a first port for connecting to a power supply motor and a second port for connecting to a fermentation tank;

[0008] The second port is arranged to expand outward in a trumpet shape.

[0009] In one embodiment, an inspection opening is provided on the outer edge of the base.

[0010] In one embodiment, the inspection port is sealed with a movable door.

[0011] The utility model also provides a vertical stirring fermentation tank, comprising the motor mounting base mentioned in the above solution, and also comprising a tank body and a motor;

[0012] The motor is fixedly connected to the first port by bolts;

[0013] The second port of the base is welded to the top of the tank body.

[0014] In one embodiment, a support seat is further provided at the bottom of the tank.

[0015] In one embodiment, a shock absorbing pad is provided at the bottom of the support seat.

[0016] The utility model has the following advantages due to the adoption of the above technical solution:

[0017] The base is specifically used to connect the motor and the fermentation tank. Since the second port is arranged to expand outward in a trumpet shape, the fitting area and contact area between the second port and the fermentation tank can be further increased. During the production process of the fermentation tank, the pressure and temperature changes in the fermentation tank, the weight of the motor itself, and the self-weight of the fermentation tank stirring shaft may cause a certain degree of deformation of the tank top. At this time, the contact surface between the second port and the fermentation tank can disperse the force transmitted when the fermentation tank body is deformed, avoid damage to the tank top, and has the advantage of higher connection stability.

[0023] To make the purpose, technical solutions, and advantages of the present invention more clear, the following is a clear and complete description of the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary persons in this field without creative work are within the scope of protection of the present invention.

[0024] Unless otherwise defined, the technical or scientific terms used in this utility model shall have the usual meanings understood by persons of ordinary skill in the field to which this utility model belongs. The words "first", "second", "third", "fourth" and similar terms used in this utility model do not indicate any order, quantity or importance, but are only used to distinguish different components. Words such as "include" or "comprise" mean that the elements or objects preceding the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. Words such as "connect" or "connected" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect.

[0025] Regarding the motor installation of a fermentation tank, since the motor will vibrate violently during operation, which in turn causes the fermentation tank body to vibrate, it is not conducive to the fermentation process of microorganisms. Therefore, it is very important to improve the stability of the motor and prevent its vibration from affecting the fermentation tank. Existing fixing methods mainly include screw fixing or fixing with multiple reinforcing ribs. However, during the production process of the fermentation tank, the pressure and temperature changes inside the fermentation tank, the weight of the motor itself, and the deadweight of the fermentation tank stirring shaft may cause the tank top to deform to a certain extent. Fermentation tanks are mostly made of stainless steel, which has less strength than iron reinforcing ribs. Therefore, when vibrated for a long time, the rigid connection between the existing fixing method and the tank top is prone to fatigue failure when the tank top is deformed, causing damage to the tank top. In response to the above technical problems, the utility model provides a motor mounting base and a vertical stirring fermentation tank. The base can serve as a transition connection component between the motor and the fermentation tank. By increasing the contact area with the fermentation tank in the connection structure with the fermentation tank, the base can disperse the force transmitted when the fermentation tank body is deformed, avoid damage to the tank top, and has the advantage of high connection stability.

[0026] The technical solution of the present utility model is described in detail below with reference to specific examples.

[0027] Reference Figure 1 、 Figure 2 as well as Figure 3 As shown, the utility model relates to a motor mounting base, the base 1 is cylindrical, and the base 1 includes a first port 3 for connecting to a power supply 2, and a second port 4 for connecting to a fermentation tank, wherein the second port 4 is trumpet-shaped and expanded outward.

[0028] For example, in this embodiment, the base 1 is specifically used to connect the motor 2 and the fermentation tank. Since the second port 4 is arranged to expand outward in a trumpet shape, the fitting area and contact area between the second port 4 and the fermentation tank can be further increased. During the production process of the fermentation tank, the pressure and temperature changes in the fermentation tank, the weight of the motor itself, and the self-weight of the fermentation tank stirring shaft may cause a certain degree of deformation of the tank top. At this time, the contact surface between the second port 4 and the fermentation tank can disperse the force transmitted when the fermentation tank body 7 is deformed, thereby avoiding damage to the tank top and having the advantage of higher connection stability.

[0029] It should be noted that, during the actual design process, the deformation threshold of the fermentation tank body 7 can be estimated according to the specific working conditions of the fermentation tank and the motor 2, thereby adjusting the set size of the second port 4 to adapt to the current deformation threshold of the fermentation tank body 7.

[0030] In this embodiment, it is more preferable that an inspection port 5 is provided on the outer edge of the base 1 to facilitate routine maintenance of the motor 2 .

[0031] When the output shaft components of the motor 2 need to be regularly maintained later, the maintenance can be performed through the provided inspection port 5 .

[0032] In this embodiment, it is more preferred that the inspection opening 5 is sealed with a movable door 6 .

[0033] The movable door 6 can close the inspection port 5. During normal operation, the movable door 6 can close the inspection port 5 to prevent foreign matter from entering the interior of the base 1 through the inspection port 5. When maintenance is required on the components of the motor 2, the components inside the base 1 can be maintained by opening the movable door 6.

[0034] The utility model also provides a vertical stirring fermentation tank, referring to Figure 1 as well as Figure 2 As shown, it includes the motor mounting base mentioned in the above scheme, as well as a tank body 7 and a motor 2, wherein the motor 2 is fixedly connected to the first port 3 by bolts, the output shaft of the motor 2 passes through the base 1 and is installed inside the fermentation tank, and the second port 4 of the base 1 is welded to the top of the tank body 7.

[0035] In this embodiment, the base 1 is specifically used to connect the motor 2 and the fermentation tank. Since the second port 4 is arranged to expand outward in a trumpet shape, the fitting area and contact area between the second port 4 and the fermentation tank can be further increased. During the production process of the fermentation tank, the pressure and temperature changes in the fermentation tank may cause a certain degree of deformation of the tank top. At this time, the contact surface between the second port 4 and the fermentation tank can disperse the force transmitted when the fermentation tank body 7 is deformed, thereby avoiding damage to the tank top and having the advantage of higher connection stability.

[0036] In this embodiment, specifically, a support base 8 is further provided at the bottom of the tank body 7. In order to further improve the stability of the tank body 7, a shock absorbing pad is provided at the bottom of the support base 8, and the shock absorbing pad is specifically a rubber pad.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
