Description

Technical Field

[0001] This utility model relates to the field of microbial agent addition technology, and in particular to a device for uniformly dispersing and adding microbial agents for fermenters. Background Technology

[0002] Fermentation technology, as an important component of modern bioengineering, is widely used in food, agriculture, environmental protection, and other fields. During fermentation, the activity and distribution of microorganisms directly affect the yield and quality of the final product. The method of adding microbial agents directly relates to the growth environment, metabolic level, and uniformity of fermentation. Therefore, how to add microbial agents evenly and effectively into the fermenter is one of the key steps to improve fermentation efficiency and ensure product quality.

[0003] In existing fermenters, the addition of microbial agents is generally done manually, by simple pumping or by gravity dripping. This can easily lead to localized high concentrations or sedimentation of the microbial agents in the tank, making it difficult for them to diffuse rapidly in the liquid phase. This can result in dead zones or uneven microenvironments during the fermentation process. Utility Model Content

[0009] Preferably, a motor is fixedly installed on the surface of the fermenter, and a second gear is fixedly installed at the output end of the motor, the second gear meshing with the first gear.

[0010] Preferably, the surface of the fermenter is equipped with a spraying mechanism for spraying microbial agents onto the upper material.

[0012] Preferably, a cam is fixedly installed on the surface of the rotating shaft to drive the second piston to move.

Detailed Implementation

[0017] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] See Figures 1-4 This utility model provides a technical solution: like Figures 1-4 As shown, a device for uniformly dispersing and adding microbial agents for a fermenter includes a fermenter 1 and a feeding hopper 2. The feeding hopper 2 is installed on the surface of the fermenter 1 for feeding materials. A discharge pipe 3 is installed at the bottom of the fermenter 1 for discharging materials. A dispersing mechanism 4 is installed on the surface of the fermenter 1 for dispersing microbial agents. The dispersing mechanism 4 includes a microbial agent tank 401, a rotating shaft 403, and an injection pipe 404. The microbial agent tank 401 is installed on the surface of the fermenter 1 for storing microbial agents. An injection pipe 402 is installed on the side wall of the microbial agent tank 401 for injecting microbial agents into the microbial agent tank 401. The rotating shaft 403 is rotatably installed in the inner cavity of the fermenter 1. The upper part of the rotating shaft 403 is inserted into the inner cavity of the microbial agent tank 401. The injection pipe 404 is installed at the bottom of the rotating shaft 403. A through hole 405 is opened in the inner cavity of the rotating shaft 403. A spray hole 406 is opened on the side wall of the injection pipe 404, and the spray hole 406 is connected to the through hole 405.

[0019] like Figures 1-4As shown, further, a first piston 407 is slidably installed inside the inoculant tank 401 for injecting the inoculant from the inoculant tank 401 into the through hole 405. An electric telescopic rod 408 is fixedly installed on the surface of the inoculant tank 401. The telescopic end of the electric telescopic rod 408 is fixedly connected to the first piston 407 for driving the first piston 407 to rise and fall. The electric telescopic rod 408 can drive the first piston 407 to move downward, injecting the inoculant from the inoculant tank 401 into the through hole 405, and spraying it into the material through the spray hole 406, realizing simultaneous mixing and spraying of inoculant, and improving the uniformity of the inoculant. The rotating shaft 403 is symmetrically and fixedly mounted with mixing rods 409 for mixing materials. A first gear 410 is fixedly mounted on the surface of the rotating shaft 403 for driving the rotating shaft 403 to rotate. A motor 411 is fixedly mounted on the surface of the fermentation tank 1. A second gear 412 is fixedly mounted on the output end of the motor 411. The second gear 412 meshes with the first gear 410. The motor 411 drives the second gear 412 to rotate, which in turn drives the first gear 410 to drive the rotating shaft 403 to rotate. Thus, the mixing rods 409 mix the bacterial agent into the materials, improving the uniformity of the bacterial agent.

[0020] With the above technical solution, when in use, the material to be fermented is put into the fermentation tank 1 through the feeding hopper 2, and the inoculant is injected into the inoculant tank 401 through the injection pipe 402. The first piston 407 can be driven to move down by the electric telescopic rod 408, injecting the inoculant in the inoculant tank 401 into the through hole 405 and spraying it into the material through the spray hole 406. At the same time, the second gear 412 is driven to rotate by the motor 411, which can drive the first gear 410 to drive the rotating shaft 403 to rotate, thereby mixing the inoculant into the material through the mixing rod 409, realizing the simultaneous mixing and spraying of inoculant, and improving the uniformity of inoculant.

[0021] like Figures 1-4 As shown, a spraying mechanism 5 is further installed on the surface of the fermenter 1 for spraying microbial agents onto the upper layer of material. The spraying mechanism 5 includes a spray pipe 501 and a nozzle 502. The spray pipe 501 is installed on the inner wall of the fermenter 1, and a number of nozzles 502 are installed on the surface of the spray pipe 501 for spraying microbial agents onto the upper layer of material to improve the uniformity of the microbial agents. The microbial agent tank 401 has symmetrically opened injection chambers 503 in its inner cavity. A second piston 504 is slidably installed in the injection chamber 503. A spring 505 is installed in the injection chamber 503. One end of the spring 505 is fixedly connected to the microbial agent tank 401, and the other end of the spring 505 is fixedly connected to the second piston 504 for driving the second piston 504 to move in the direction of the rotating shaft 403.

[0022] like Figures 1-4As shown, a cam 506 is fixedly mounted on the surface of the rotating shaft 403 to drive the second piston 504 to move. Under the action of the spring 505, the second piston 504 is driven to press against the side wall of the cam 506. As the rotating shaft 403 rotates, when the protrusion of the cam 506 contacts the second piston 504, the spring 505 contracts and the second piston 504 moves backward. When the protrusion of the cam 506 moves away from the second piston 504, the spring 505 returns to its original position and the second piston 504 moves forward, realizing the reciprocating movement of the second piston 504. A first one-way valve 507 and a second one-way valve 508 are installed on the side wall of the injection chamber 503. The first one-way valve 507 is connected to the inner cavity of the bacterial agent tank 401 by a pipe for liquid inlet. The second one-way valve 508 is connected to the spray pipe 501 by a pipe for liquid outlet.

[0023] With the above technical solution, during use, under the action of spring 505, the second piston 504 is driven to press tightly against the side wall of cam 506. As the rotating shaft 403 rotates, when the protrusion of cam 506 contacts the second piston 504, spring 505 contracts and the second piston 504 moves backward. When the protrusion of cam 506 moves away from the second piston 504, spring 505 returns to its original position and the second piston 504 moves forward, realizing the reciprocating movement of the second piston 504. This causes the first one-way valve 507 and the second one-way valve 508 to alternately open, sending the bacterial agent in the bacterial agent tank 401 into the spray pipe 501, and finally spraying it out from the nozzle 502 onto the surface of the upper material, improving the uniformity of the bacterial agent.

[0024] Preferably, during use, the material to be fermented is fed into the fermentation tank 1 through the feeding hopper 2, and the inoculant is injected into the inoculant tank 401 through the injection pipe 402. The first piston 407 can be driven to move down by the electric telescopic rod 408, injecting the inoculant in the inoculant tank 401 into the through hole 405 and spraying it into the material through the spray hole 406. At the same time, the second gear 412 is driven to rotate by the motor 411, which in turn drives the first gear 410 to drive the rotating shaft 403 to rotate, thereby mixing the inoculant into the material through the mixing rod 409, realizing the simultaneous mixing and spraying of the inoculant, and improving the uniformity of the inoculant.

[0025] Preferably, during use, under the action of spring 505, the second piston 504 is driven to press tightly against the side wall of cam 506. As the rotating shaft 403 rotates, when the protrusion of cam 506 contacts the second piston 504, spring 505 contracts and the second piston 504 moves backward. When the protrusion of cam 506 moves away from the second piston 504, spring 505 returns to its original position and the second piston 504 moves forward, realizing the reciprocating movement of the second piston 504. This causes the first one-way valve 507 and the second one-way valve 508 to alternately open, sending the bacterial agent in the bacterial agent tank 401 into the spray pipe 501, and finally spraying it out from the nozzle 502 onto the surface of the upper material, thereby improving the uniformity of the bacterial agent.
