Description

Technical Field

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

[0002] See Figure 1 Traditional fermenters include a feed pipe, an ammonia pipe, and a stirring device. The feed pipe is used to introduce the liquid into the tank, the ammonia pipe is used to introduce ammonia into the tank to adjust the pH value required for microbial fermentation, and the stirring device is used to mix the materials in the tank evenly.

[0003] Traditional fermenters have the following drawbacks:

[0004] 1. After the feed pipe enters the fermentation tank, the liquid directly impacts the inner wall of the tank, generating a large number of bubbles, which affects fermentation.

[0005] 2. The feed is not equipped with metering equipment, making it difficult to control the feeding speed.

[0006] 3. The outlet of the ammonia water pipe is located above the liquid surface inside the tank, which means that the ammonia water is pumped away before it enters the liquid, resulting in waste.

[0007] 4. When multiple mixing blades of the mixing equipment are at the same horizontal position, the overall mixing effect is poor. Utility Model Content

[0008] In view of the above, this utility model provides a novel fermenter, which aims to solve at least one of the defects pointed out in the background art.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] This utility model provides a novel fermentation tank, comprising:

[0011] The tank body has a feeding port on its side wall; one end of the feeding port extends into the tank body and is flared.

[0012] A feed pipe is connected to the inlet of the measuring cup, and the feed pipe has a first electrically controlled valve;

[0013] A measuring cup, the outlet of which is connected to the feed port via a conduit, the conduit having a second electrically controlled valve;

[0014] A trachea is connected to the inlet of the measuring cup;

[0015] A flexible buffer mechanism is connected to the feed interface and located on the discharge path of the feed interface.

[0016] In some embodiments of this utility model, the flexible buffer mechanism includes:

[0017] a support plate connected to the feeding interface through a connecting assembly;

[0018] a flexible convex provided on one side of the support plate facing the feeding interface.

[0019] In some embodiments of the present application, the flexible convex is spherical on one side facing the feeding interface.

[0020] In some embodiments of the present application, the flexible convex is connected with an air nozzle, and the air nozzle is provided with a pressure relief valve.

[0023] a support rod hingedly connected to the connecting sleeve at one end and connected to the support plate at the other end after passing through the limiting gap.

[0024] In some embodiments of the present application, the support rod is hingedly connected to the support plate.

[0025] In some embodiments of the present application, further comprising an ammonia water pipe, and the outlet of the ammonia water pipe is below the liquid level in the tank.

[0026] In some embodiments of the present application, further comprising a stirring shaft in the tank and a plurality of stirring blades arranged along the length direction of the stirring shaft.

[0027] The embodiments of the present application have at least the following advantages or beneficial effects:

[0028] 1. By providing the measuring cup, the liquid to be fed into the tank can be quantified, and by sequentially opening and closing the first electric control valve and the second electric control valve, and by introducing the gas with the specified pressure into the air pipe, the control of the feeding speed and the feeding amount is realized.

[0029] 2. Since one end of the feeding interface extends into the tank and is flared, the diameter of the outlet of the feeding interface changes greatly, which can effectively slow down the flow rate of the liquid and weaken the impact of the liquid on the inner wall of the tank, thereby reducing the generation of bubbles.

[0030] 3. By providing the flexible buffering mechanism, part of the impact force of the liquid can be absorbed, further weakening the impact of the liquid on the inner wall of the tank and reducing the generation of bubbles.

[0049] The embodiments of the utility model will be described in detail below.

[0050] Embodiment 1

[0051] Referring to Figures 1-3 , the embodiment provides a novel fermentation tank, which comprises a tank body 1, an ammonia pipe 2, a stirring mechanism, a feeding pipe 4, a measuring cup 5, an air pipe 6 and a flexible buffer mechanism 7.

[0052] The lower side wall of the tank body 1 is provided with a feeding interface 11. One end of the feeding interface 11 extends into the tank body 1 and is flared.

[0053] The outlet of the ammonia pipe 2 is close to the inner bottom of the tank body 1.

[0054] The stirring mechanism comprises a stirring shaft 31 located in the tank body 1 and a plurality of stirring blades 32 arranged at intervals along the length direction of the stirring shaft 31. The feeding interface 11 is located below the stirring blades 32.

[0055] The feeding pipe 4 is connected with the inlet of the measuring cup 5, and the feeding pipe 4 is provided with a first electric control valve 41.

[0056] The outlet of the measuring cup 5 is connected with the feeding interface 11 through a conduit 51, and the conduit 51 is provided with a second electric control valve 52.

[0057] The air pipe 6 is connected with the inlet of the metering cup 5, and pressure gas is introduced into the metering cup 5 through the air pipe 6 to control the feed pressure.

[0058] The flexible buffering mechanism 7 is connected with the flared end of the feed interface 11 and is located on the discharge path of the feed interface 11.

[0059] Through the arrangement of the metering cup 5, the feed liquid to be introduced into the tank body 1 is quantified, and the orderly opening and closing of the first electric control valve 41 and the second electric control valve 52 are matched, and the gas with the specified pressure is introduced into the air pipe 6, so that the control of the feeding speed and the feeding amount is realized.

[0060] Since one end of the feed interface 11 extends into the tank body 1 and is flared, the diameter of the outlet of the feed interface 11 changes greatly, which can effectively slow down the flow rate of the feed liquid and weaken the impact of the feed liquid on the inner wall of the tank body 1, thereby reducing the generation of bubbles.

[0061] Through the arrangement of the flexible buffering mechanism 7, the partial impact force of the feed liquid can be absorbed, and the impact of the feed liquid on the inner wall of the tank body 1 is further weakened, thereby reducing the generation of bubbles.

[0062] The outlet of the ammonia water pipe 2 is close to the inner bottom of the tank body 1, so that the outlet of the ammonia water pipe 2 can be located below the liquid level in the tank body 1. In this way, the situation that the ammonia water is not yet introduced into the feed liquid but is drawn away no longer exists, and the waste of ammonia water is avoided.

[0063] By arranging the plurality of stirring blades 32 along the length direction of the stirring shaft 31, the stirring effect on the whole feed liquid in the tank body 1 is strengthened. By locating the feed interface 11 below the stirring blades 32, the feed liquid introduced into the tank body 1 from the feed interface 11 can be quickly stirred and mixed uniformly with other feed liquids in the tank by the stirring blades 32 in the process of flowing upward.

[0064] Embodiment 2

[0065] Referring to Figures 1-3 In this embodiment, the flexible buffering mechanism 7 includes a support plate 71 and a flexible protrusion 72.

[0066] The support plate 71 is connected with the feed interface 11 through a connecting assembly.

[0067] The flexible protrusion 72 is arranged on the side of the support plate 71 facing the feed interface 11, and the side of the flexible protrusion 72 facing the feed interface 11 is spherical. The flexible protrusion 72 is like an air bag, and the flexible protrusion 72 is connected with a gas nozzle 73, and the gas nozzle 73 is provided with a pressure relief valve 731.

[0068] When the flexible protrusion 72 is impacted by the feed liquid, it will deform and consume part of the kinetic energy of the feed liquid, thereby weakening the impact of the feed liquid on the inner wall of the tank body 1 during feeding and reducing the generation of bubbles.

[0069] By making the flexible protrusion 72 spherically shaped towards one side of the feed interface 11, both good buffering effect and guiding and dispersing effect on the feed liquid can be achieved.

[0070] Considering that the temperature in the fermentation tank is relatively high, the gas in the flexible protrusion 72 may expand after being heated, which may reduce the elasticity of the flexible protrusion 72. Therefore, a pressure relief valve 731 is arranged on the air nozzle 73 to automatically release pressure when the air pressure in the flexible protrusion 72 reaches a threshold value, so as to prevent the flexible protrusion 72 from being stretched too much and thus reducing the buffering effect.

[0071] The connecting assembly includes a connecting sleeve 74 and a supporting rod 75.

[0072] The connecting sleeve 74 is threadedly connected to the outer wall of the feed interface 11, and the connecting sleeve 74 has an extension 76 with a limiting notch 77.

[0073] One end of the supporting rod 75 is hingedly connected to the connecting sleeve 74, and the other end is connected to the upper part of the supporting plate 71 after passing through the limiting notch 77.

[0074] By arranging the connecting sleeve 74 and the supporting rod 75, the supporting plate 71 can be conveniently connected to the feed interface 11.

[0075] Further, the supporting rod 75 is hingedly connected to the supporting plate 71; when the gas pressure in the metering cup 5 is relatively high, the supporting plate 71 can be pushed to increase the horizontal distance between the flexible protrusion 72 and the feed interface 11, so that the feed liquid can be prevented from being subjected to excessive rebound force from the flexible protrusion 72.

[0076] Finally, it should be noted that the above is only a preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes, and the embodiments of the present application and the features in the embodiments can be arbitrarily combined without conflict. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
