Description

Technical Field

[0001] The utility model relates to the technical field of feed fermentation, in particular to a silage fermentation device. Background Art

[0002] Silage fermentation is an important process for making feed, mainly used to process crop straw and silage to improve its nutritional value and long-term preservation. The silage fermentation process can be divided into the following stages: initial stage. In the initial stage of silage fermentation, the oxygen in the raw materials gradually decreases, and lactic acid bacteria begin to multiply and produce lactic acid in an anaerobic environment. This stage usually lasts for a few days, during which plant cells are still respiring, releasing heat and carbon dioxide, and when the silage is stirred, oxygen will accelerate the metabolic activity of microorganisms, and the internal temperature will even rise to 60 degrees. Excessive temperature can easily lead to the death of beneficial bacteria in the strain, resulting in fermentation failure, causing the silage to rot and deteriorate. As oxygen is consumed, the reproduction of lactic acid bacteria reaches a peak, producing a large amount of lactic acid and lowering the pH value of the feed. This stage is the key to the entire fermentation process, because the accumulation of lactic acid will inhibit the growth of other harmful microorganisms and protect the nutrients of the feed. When the pH value drops below 4.2, most microorganisms stop multiplying, the activity of lactic acid bacteria is also inhibited, and the fermentation process stops. At this point, the feed enters a stable storage state and can be stored for a long time under closed conditions to maintain its nutritional value.

This traditional stirring method is not only time-consuming and labor-intensive, but also greatly reduces the overall processing efficiency of silage. A sealed fermentation device for silage processing includes a barrel body, a top cover is provided on the top of the barrel body, and a sealing plate is fixedly connected to the bottom of the top cover, and a sealing groove for matching with the sealing plate is provided on the top of the barrel body.

[0004] In the above scheme, when the silage is stirred, the oxygen in the barrel will accelerate the metabolic activity of the microorganisms, thereby causing the fermented silage to generate high temperature, affecting the quality of the silage fermentation. Utility Model Content

[0025] Embodiment:

[0026] Referring to Figures 1-4 , a silage fermentation device includes a fermentation tank 1. A heat dissipation pipe 2 is provided on the outer wall of the fermentation tank 1, and the heat dissipation pipe 2 is spiral and sleeved on the outer wall of the fermentation tank 1. A coolant is filled in the heat dissipation pipe 2, which can be used to absorb the heat generated during the stirring process of the fermentation tank 1. A connecting shaft 3 is fixedly connected inside the fermentation tank 1, and stirring blades are also fixedly connected to the connecting shaft 3, which can be used to stir the feed in the fermentation tank 1. A cover body is detachably connected to the top of the fermentation tank 1 for sealing the fermentation tank 1. A drive motor or a hydraulic motor can be installed at the bottom of the fermentation tank 1 to rotate the internal connecting shaft 3.

[0027] Moreover, the connecting shaft 3 extends to the outside of the fermentation tank 1 and is fixedly connected with a main gear 301. A transmission disk 5 is fixedly connected to the bottom of the fermentation tank 1. A rotating shaft 4 is rotatably connected to the transmission disk 5, and a turbine blade 501 is fixedly connected to the rotating shaft 4. The input end of the heat dissipation pipe 2 is fixedly connected to one side of the transmission disk 5. A heat dissipation box 7 is fixedly connected to the bottom of the fermentation tank 1, and the other side of the transmission disk 5 is connected to the heat dissipation box 7 through a connecting pipe. The output end of the heat dissipation pipe 2 is fixedly connected to the heat dissipation box 7.

[0028] When the rotating shaft 4 rotates, it can drive the turbine blade 501 inside the transmission disk 5 to rotate, thereby enabling the coolant to circulate in the heat dissipation pipe 2. The coolant can more effectively contact the outer wall surface of the heat dissipation pipe 2, thereby improving the heat conduction efficiency. Then the coolant absorbs the heat on the outer wall of the fermentation tank 1 and takes away the heat through the circulating flow to achieve the purpose of heat dissipation.

[0029] Moreover, the rotating shaft 4 extends outside the transmission disc 5 and is fixedly connected with an auxiliary gear 401. A main gear 301 is fixedly connected to the connecting shaft 3. Then, the main gear 301 is meshed with the auxiliary gear 401. By rotating the connecting shaft 3, the auxiliary gear 401 is driven to rotate, which drives the turbine blade 501 inside the transmission disc 5 to rotate, thereby circulating the coolant in the heat dissipation pipe 2.

[0030] To further improve the heat dissipation effect of the heat dissipation pipe 2, heat dissipation fins 8 made of copper or aluminum are arranged in the heat dissipation box 7, and the other end of the heat dissipation fins 8 extends outside the heat dissipation box 7. The coolant circulates in the heat dissipation pipe 2, then flows through the inside of the heat dissipation box 7, and the heat of the coolant is dissipated through the heat dissipation fins 8. This can effectively increase the heat exchange effect between the coolant and the external environment, improve the heat dissipation efficiency, and the heat dissipation fins 8 can increase the speed of heat transfer, enabling the coolant to transfer heat to the surface of the heat dissipation fins 8 faster, thereby accelerating the dissipation of the heat inside the fermentation tank 1. When stirring the inside of the fermentation tank 1, the internal temperature may even rise to 60 degrees. At this time, it is necessary to cool the fermentation tank 1 to lower the temperature.

[0031] Meanwhile, a pressurizing disc 6 is fixedly connected to the bottom of the fermentation tank 1, and the end of the rotating shaft 4 extends into the pressurizing disc 6 and is fixedly connected with a fan blade 601. When the rotating shaft 4 rotates, the fan blade 601 can be driven to rotate, thereby making the air inside the pressurizing disc 6 flow. An air inlet and an air outlet are arranged on the pressurizing disc 6. Air enters through the air inlet and exits through the air outlet, and the air outlet on the pressurizing disc 6 is directed towards the heat dissipation fins 8.

[0032] Moreover, a diversion channel 9 is arranged at the bottom of the heat dissipation box 7, and the heat dissipation fins 8 outside the heat dissipation box 7 extend into the diversion channel 9. The diversion channel 9 is communicated with the air outlet on the pressurizing disc 6. By the rotation of the fan blade 601 to generate wind, the wind is used to take away the heat on the heat dissipation fins 8, accelerating the dissipation and transfer of heat, improving the heat dissipation efficiency, thereby releasing the heat to the outside faster, making the cooling speed of the coolant in the heat dissipation pipe 2 faster, and further reducing the temperature generated during the process of stirring the feed in the fermentation tank 1, and improving the fermentation quality of the silage feed.

[0033] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
