Description

Technical Field

[0001] This utility model relates to a fermentation tank, specifically a fermentation tank for the production of feed additives, and belongs to the technical field of feed additive fermentation tanks. Background Technology

[0002] Feed additives refer to small or trace amounts of substances added during feed production, processing, and use. They play a significant role in enhancing the nutritional value of feed, improving animal production performance, ensuring animal health, reducing feed costs, and improving the quality of livestock products. Feed additive fermentation tanks are deep liquid culture equipment for microorganisms with sterilization, temperature control, stirring, oxygen supply, and automated control functions. By precisely controlling parameters such as temperature, pH value, and dissolved oxygen, they provide the optimal growth environment for microorganisms, achieving efficient production of feed additives.

[0003] Current feed additive fermentation tanks can ferment both liquid and solid additives. When fermenting liquid additives, the additives are added to the fermentation tank through a delivery pipe. When fermenting solid additives, the feed inlet is opened and the solid additives are poured into the fermentation tank. The feed inlet opening is relatively small, and when pouring, a large amount of solid additives directly and quickly come into contact with the fermentation liquid, forming large clumps. These clumps of solid additives are not easy to break up, requiring a long period of stirring, which affects the fermentation speed or results in uneven fermentation. Utility Model Content

[0004] The purpose of this invention is to provide a fermentation tank for the production of feed additives to solve the above problems. It is equipped with a component that breaks up solid fermentation agents when they are fed, so as to avoid clumping and uneven fermentation.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a fermentation tank for feed additive production, comprising a tank body, a feeding mechanism installed on the tank body, the feeding mechanism including a feeding port, a feeding port with a straight structure on the tank body, two supports symmetrically installed on the tank body about the feeding port, a hopper fixedly connected to the two supports, a rotating cylinder rotatably connected inside the hopper, a collection groove opened on the outer shell of the rotating cylinder, the collection groove communicating with the bottom opening of the hopper, a feeding pipe installed on the tank body, the feeding port located at the bottom of the rotating cylinder, and a sealing plate provided on the feeding port.

[0006] Specifically, the feeding mechanism also includes a rotating shaft, which is rotatably connected to the hopper and located above the rotating drum. A second gear is keyed to the end of the rotating shaft, and a first gear is keyed to the end of the rotating drum. The first gear and the second gear mesh with each other. A second motor is installed on the side of the hopper, and the output end of the second motor is fixedly connected to the end of the rotating drum.

[0007] Specifically, the feeding mechanism also includes blades, and multiple sets of blades are equidistantly arranged on the rotating shaft, and the diameter of gear one is larger than the diameter of gear two.

[0008] Specifically, the feeding mechanism also includes a guide plate, and the guide plate is inclinedly welded between the two supports and the tank body.

[0009] Specifically, the tank is equipped with a stirring mechanism, which includes a motor. The motor is installed on the top of the tank, and the output end of the motor is connected to a stirring shaft via a coupling. Multiple sets of stirring blades are provided on the stirring shaft located inside the tank.

[0010] Specifically, the tank is equipped with a detection mechanism, which includes a sampling tube. The tank is also equipped with a pH meter and a dissolved oxygen detector.

[0011] Specifically, the tank is equipped with a temperature control mechanism, which includes a temperature detector and a heat insulation plate. The heat insulation plate is installed inside the tank, and a temperature detector that contacts the heat insulation plate is installed on the tank. The inner wall of the tank is spirally provided with a conveying cavity, and an inlet pipe and an outlet pipe that communicate with the conveying cavity are installed on the tank.

[0012] Specifically, the tank is equipped with an exhaust mechanism, which includes an exhaust pipe. The exhaust pipe is installed on the top of the tank and a filter is installed on the exhaust pipe.

[0013] Specifically, the tank is equipped with a discharge mechanism, which includes a discharge pipe. The bottom of the tank is connected to the discharge pipe, and a steam pipe is vertically installed on the discharge pipe. Valves are installed on both the steam pipe and the discharge pipe. A sterile air duct is installed at the bottom of the tank.

[0014] The beneficial effects of this utility model are as follows: when solid additives are added into the hopper, the hopper can be sealed regardless of whether the collection groove on the rotating drum is facing upwards or downwards. When the collection groove opening is upwards, the solid additives at the bottom of the hopper can be collected. Then, the sealing plate located at the top of the tank is opened, and the discharge port located at the top of the tank is opened. When the collection groove on the rotating drum is downwards, the material is poured out in a curtain-like manner. The poured solid additives are poured into the inside of the tank. During the material discharge, the solid additives are dispersed, preventing a large amount of solid additives from falling rapidly into the inside of the tank and coming into contact with the fermentation liquid, causing clumping.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5As shown, a fermentation tank for feed additive production includes a tank body 1. The tank body 1 is equipped with a detection mechanism 4, an exhaust mechanism 5, a temperature control mechanism 6, a discharge mechanism 7, a stirring mechanism 2, and a feeding mechanism 3. The feeding mechanism 3 includes a feeding port 305. The tank body 1 has a straight feeding port 305. Two supports 304 are symmetrically installed on the tank body 1 about the feeding port 305. A hopper 301 is fixedly connected to the two supports 304. A rotating drum 308 is rotatably connected inside the hopper 301. A collection groove 309 is provided on the outer shell of the rotating drum 308. The collection groove 309 communicates with the bottom opening of the hopper 301. A second motor 302 is installed on the side of the hopper 301. The output end of the second motor 302 is fixedly connected to the end of the rotating drum 308. A feeding pipe 303 is installed on the tank body 1. The feeding port 305 is located at the bottom of the rotating drum 308. A sealing plate 311 is provided on the feeding port 305.

[0024] As a technical optimization of this utility model, the feeding mechanism 3 further includes a rotating shaft 306. The rotating shaft 306, located above the rotating cylinder 308, is rotatably connected to the hopper 301. A gear 2 313 is keyed to the end of the rotating shaft 306, and a gear 1 312 is keyed to the end of the rotating cylinder 308. The gear 1 312 and the gear 2 313 mesh with each other. The feeding mechanism 3 also includes blades 307. Multiple sets of blades 307 are equidistantly arranged on the rotating shaft 306. The diameter of the gear 1 312 is larger than the diameter of the gear 2 313. When the rotating cylinder 308 rotates, the gear 1 312 drives the gear 2 313 to rotate, thus realizing that the rotating shaft 306 drives the blades 307 to stir the additives inside the hopper 301, preventing blockage and facilitating feeding.

[0025] As a technical optimization of this utility model, the feeding mechanism 3 also includes a guide plate 310. The guide plate 310 is inclinedly welded between the two supports 304 and the tank 1, so that the additives poured out of the collection tank 309 on the rotating drum 308 can be accurately poured into the inside of the feeding port 305.

[0026] As a technical optimization of this utility model, the stirring mechanism 2 includes a motor 201. The motor 201 is installed on the top of the tank 1. The output end of the motor 201 is connected to the stirring shaft 202 through a coupling. Multiple sets of stirring blades 203 are provided on the stirring shaft 202 located inside the tank 1. Starting the motor 201 enables the stirring blades 203 to stir the fermentation additives, which is beneficial for uniform mixing and fermentation.

[0027] As a technical optimization of this utility model, the detection mechanism 4 includes a sampling tube 401, the sampling tube 401 is installed on the tank 1, and a pH meter 402 and a dissolved oxygen detector 403 are installed on the tank 1 to realize sampling and observation of fermentation during fermentation.

[0028] As a technical optimization of this utility model, the temperature control mechanism 6 includes a temperature detector 603 and a heat preservation plate 605. The heat preservation plate 605 is installed inside the tank body 1, and the temperature detector 603 that abuts against the heat preservation plate 605 is installed on the tank body 1. The inner wall of the tank body 1 is provided with a spiral conveying cavity 604. The tank body 1 is provided with an inlet pipe 601 and an outlet pipe 602 that communicate with the conveying cavity 604. Hot water or cold water is connected to the inlet pipe 601 so that hot water or cold water enters the interior of the conveying cavity 604 to cool or keep the tank body 1 warm.

[0029] As a technical optimization of this utility model, the exhaust mechanism 5 includes an exhaust pipe 501. The exhaust pipe 501 is installed on the top of the tank body 1, and a filter 502 is installed on the exhaust pipe 501 to realize the discharge and filtration of the gas generated during fermentation.

[0030] As a technical optimization of this utility model, the discharge mechanism 7 includes a discharge pipe 702. The bottom of the tank body 1 is connected to the discharge pipe 702. A steam pipe 701 is vertically installed on the discharge pipe 702. Valves 703 are installed on both the steam pipe 701 and the discharge pipe 702. A sterile air pipe 704 is installed at the bottom of the tank body 1. Steam can be added into the tank body 1 through the steam pipe 701, and air can be added into the tank body 1 through the sterile air pipe 704 for reaction. The discharge pipe 702 can discharge the material.

[0031] In use, this invention involves installing the tank 1 using a mounting bracket. When feeding liquid feed additives, the feed pipe 303 is directly connected to the pipe supplying the liquid fermenting agent. The fermentation method is the same for both liquid and solid fermenting agents. When fermenting solid feed additives, the solid additive is added to the inside of the hopper 301. The hopper 301 can be sealed regardless of whether the collection trough 309 on the rotating drum 308 is facing upwards or downwards. When the collection trough 309 is facing upwards, the solid additive at the bottom of the hopper 301 can be collected. Then, the tank 1 is opened. The top sealing plate 311 opens the discharge port 305 at the top of the tank 1, further activating the motor 302 to drive the rotating drum 308 inside the hopper 301. When the collection trough 309 on the rotating drum 308 faces downwards, material is poured out in a curtain-like manner. The poured solid additives are guided into the interior of the tank 1 by two guide plates 310. During the feeding process, the solid additives are dispersed, preventing a large amount of solid additives from falling rapidly into the interior of the tank 1 and coming into contact with the fermentation liquid, causing clumping. Clumping requires prolonged stirring, wasting fermentation time, and uneven stirring can also lead to fermentation problems. Uneven fermentation affects feed quality. When motor 2 (302) drives the collection trough 309 on the rotating drum 308 upwards again, it collects solid additives again. When the collection trough 309 rotates downwards, the feed is poured out. During fermentation, the sealing plate 311 covers the feed inlet 305 to prevent bacteria from entering. When the rotating drum 308 rotates, gear 1 (312) drives gear 2 (313) to rotate, which in turn causes the rotating shaft 306 to drive the blades 307 to rotate above the rotating drum 308, thus stirring the solid additives above the rotating drum 308 and preventing blockages that affect feeding. Finally, motor 1 (201) can be started to activate the stirring blades 203 to stir the fermenting additives. Adding agents and stirring facilitates uniform mixing and fermentation. Sampling tube 401, pH meter 402, and dissolved oxygen detector 403 are used to sample and observe the fermentation process. Hot or cold water is connected to the inlet pipe 601 to allow hot or cold water to enter the conveying chamber 604 for cooling or heat preservation of the tank 1. Gases generated during fermentation are discharged and filtered through the exhaust pipe 501 and filter 502. Steam can be added to the tank 1 through the steam pipe 701, and air can be added to the tank 1 through the sterile air pipe 704 for reaction. Material can be discharged through the discharge pipe 702.
