Description

Technical Field

[0001] This utility model relates to the field of cattle and sheep feed production and processing technology, specifically to a fermentation device for cattle and sheep feed production. Background Technology

[0002] Fermentation is a common processing method in cattle and sheep feed production, which can improve the nutritional value of feed, enhance palatability, and extend shelf life. A published Chinese patent, CN220537786U, discloses a feed production fermentation device, relating to the field of feed production technology. The device includes a fermentation tank with a feed hopper at the top. A motor is fixedly mounted on the top of the fermentation tank via a bracket. The output end of the motor is connected to a first stirring rod inside the fermentation tank. The first stirring rod is equipped with multiple stirring components, and a drive bevel gear is connected to the bottom of the first stirring rod.

[0003] The aforementioned disclosed patents have the following problems in actual use:

[0004] 1. During fermentation, the protein and sulfur-containing amino acids (such as methionine and cysteine) in feed are decomposed by microorganisms, producing gases such as ammonia and hydrogen sulfide. Ammonia has an irritating odor, and high concentrations can harm the respiratory system of animals and operators. Hydrogen sulfide is a highly toxic gas; low concentrations have a rotten egg smell, while high concentrations can cause suffocation or even death. This fermentation device does not have a fermentation gas treatment function; the direct emission of untreated fermentation gases will pollute the environment and affect the safety of the working environment.

[0005] 2. The fermentation device does not have a self-cleaning function, making cleaning inconvenient. Utility Model Content

[0006] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a fermentation device for cattle and sheep feed production. By setting hydrogen sulfide adsorption plates and ammonia adsorption plates in the exhaust pipe, it can adsorb harmful gases such as ammonia and hydrogen sulfide produced by microbial decomposition of cattle and sheep feed during fermentation, thereby reducing the pollution of the environment caused by the emission of harmful gases such as ammonia and hydrogen sulfide and improving the safety of the working environment. By setting rubber blocks on the stirring paddle, a cleaning function can be added on the basis of the original stirring function, improving the convenience of cleaning the tank. This solves the problem that the fermentation devices used in the prior art do not have fermentation gas treatment function and self-cleaning function.

[0007] To achieve the above and other related objectives, this utility model provides a fermentation device for cattle and sheep feed production, including a support frame and a tank mounted on the support frame. The upper end of the tank is provided with a feed pipe and an exhaust pipe, and the lower end is provided with a discharge pipe. The tank is provided with a stirring mechanism, which includes a stirring motor, a rotating shaft, and several stirring paddles. The stirring motor is mounted on the upper end of the tank, the rotating shaft is rotatably mounted in the tank and its upper end is connected to the output end of the stirring motor, and several stirring paddles are staggered on opposite sides of the rotating shaft, and the several stirring paddles mounted on opposite sides of the rotating shaft are equidistantly distributed vertically in the tank.

[0008] The exhaust pipe is equipped with a hydrogen sulfide adsorption plate and an ammonia adsorption plate.

[0009] The exhaust pipe has a first chamber and a second chamber. The first chamber is located above the second chamber and its inner diameter is larger than that of the second chamber. The first chamber has a first convex ring and an ammonia adsorption plate is detachably placed on the upper end of the first convex ring. The second chamber has a second convex ring and a hydrogen sulfide adsorption plate is detachably placed on the upper end of the second convex ring.

[0010] Both the hydrogen sulfide adsorption plate and the ammonia adsorption plate have an inner cavity. The inner cavity of the hydrogen sulfide adsorption plate is filled with activated carbon, and the inner cavity of the ammonia adsorption plate is filled with zeolite. The upper and lower end faces of both the hydrogen sulfide adsorption plate and the ammonia adsorption plate are provided with through holes that extend into the inner cavity.

[0011] The end of the stirring paddle is provided with a rubber block, the cross-sectional shape of which is arc-shaped. The rubber block is in frictional contact with the inner wall of the tank. Furthermore, the rubber blocks provided on several stirring paddles work together to rotate and cover the inner wall of the corresponding stirring area of ​​the tank.

[0012] In one embodiment of the present invention, a butterfly valve is provided in the discharge pipe. The butterfly valve includes a valve body, a valve disc, a rotary motor, and a drive shaft. The drive shaft is movably mounted on the valve body through a rotating connector. The valve disc is mounted on the drive shaft. The rotary motor is mounted on the outer end of the valve body and its output end is connected to the drive shaft.

[0013] In one embodiment of the present invention, the discharge pipe is connected to a drain pipe at its side end above the butterfly valve, and a valve is provided on the drain pipe; a filter plate is provided at one end of the drain pipe connected to the discharge pipe.

[0014] In one embodiment of the present invention, the upper end of the feed pipe is a wide opening, and a detachable cover plate is fitted onto the wide opening of the feed pipe.

[0015] As described above, the fermentation device for cattle and sheep feed production of this utility model has the following beneficial effects:

[0016] 1. By installing hydrogen sulfide adsorption plates and ammonia adsorption plates in the exhaust pipe, harmful gases such as ammonia and hydrogen sulfide produced by the decomposition of proteins and sulfur-containing amino acids (such as methionine and cystine) in cattle and sheep feed during fermentation can be adsorbed by the hydrogen sulfide adsorption plates and ammonia adsorption plates, reducing the pollution of the environment caused by harmful gases such as ammonia and hydrogen sulfide, improving the safety of the working environment, and preventing secondary pollution of cattle and sheep feed by harmful gases, which is conducive to improving the quality of feed production.

[0017] 2. By setting rubber blocks on the mixing paddle, the arc-shaped cross-section design of the rubber blocks can fit against the curved inner wall of the tank when the rotating shaft rotates in the arc-shaped convex direction, ensuring normal mixing function. When the rotating shaft rotates in the opposite arc-shaped convex direction, it scrapes the curved inner wall of the tank, adding a cleaning function on the basis of the original mixing function, improving the convenience of cleaning the tank, and thus ensuring the safety of cattle and sheep feed production.

[0018] 3. By setting up a drain pipe, when the fermentation liquid needs to be removed after the cattle and sheep feed fermentation is completed, the fermentation liquid can be filtered out by opening the drain pipe, maintaining the appropriate humidity of the feed and improving the quality of feed production;

[0019] 4. This utility model has a reasonable overall design and compact structure. The design of the hydrogen sulfide adsorption plate and ammonia adsorption plate can effectively adsorb harmful gases produced by microbial decomposition during the fermentation of cattle and sheep feed, improving the safety of the working environment. The design of the rubber block can add a cleaning function on the basis of the original stirring function, improving the convenience of cleaning the tank. The setting of the drain pipe can filter out excess fermentation liquid, improving the quality of feed production. This device is not only suitable for the fermentation of cattle and sheep feed, but can also be used for the fermentation production of other livestock and poultry feed, and has a wide range of application prospects.
