Description

Technical Field

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

[0002] Silage is the process of sealing green fodder and fermenting it to produce organic acids. The silage is isolated from the air, will not spoil for a long time, and can reduce the loss of nutrients.

[0003] However, the existing fermentation tank includes a tank body and a top cover. When in use, the fermentation material is filled into the tank body cavity, and then sealed by the top cover. By inputting sufficient material into the tank body, the material can be maintained at a certain degree of compaction density in the tank body through the restriction of the fermentation tank, thereby ensuring the stable compaction of the silage raw materials. However, when the sample is small, it is impossible to effectively maintain the silage raw materials in a compacted state only by the fermentation tank, so the silage raw materials can only be stored in bags. However, bagged storage of silage materials has many disadvantages, such as the fermentation environment is greatly affected by the external environment, the fermentation environment is unstable, and the fermentation environment cannot be monitored, etc.

[0004] Therefore, it is urgent to propose a silage fermentation tank, which can provide a stable fermentation environment for different amounts of silage raw materials. Utility Model Content

The pressure cover can slide downward in the tank body along the slide rail until the material is compacted by the pressure cover. At this time, the pressure cover separates the tank body into a fermentation chamber and a pressure relief chamber. The gas generated by the raw materials in the fermentation chamber during the fermentation process is released into the pressure relief chamber through a one-way exhaust valve, thereby maintaining the stability of the pressure in the fermentation chamber and ensuring the stability of the fermentation environment.

A slide rail 2 is fixedly arranged on the inner wall of the tank body 1, and the slide rail 2 extends along the axial direction of the tank body 1. The tank cover includes a pressure cap 3, which can be used to compact the material. A notch 4 is arranged on the pressure cap 3, and the pressure cap 3 can slide onto the slide rail 2 through the notch 4, thereby realizing a sliding connection between the pressure cap 3 and the slide rail 2, so that the pressure cap 3 can also slide along the axis of the tank body 1. The size of the pressure cap 3 is preferably matched with the size of the inner wall of the tank body 1, and the outer edge of the pressure cap 3 fits with the inner wall of the tank body 1. The pressure cap 3 can seal the tank body 1 to a certain extent, and the tank body 1 is divided into a pressure relief chamber and a fermentation chamber by the pressure cap 3. A one-way exhaust valve 5 is arranged on the pressure cap 3, and the gas in the fermentation chamber is discharged into the pressure relief chamber through the one-way exhaust valve 5.

[0031] Working principle: Fermentation materials (including silage raw materials) are loaded into the tank body 1, and auxiliary tools are used to preliminarily compact the raw materials. Then, the pressure cap 3 is slid from the tank mouth onto the slide rail 2, so that the pressure cap 3 is slidably connected with the slide rail 2, and the pressure cap 3 can slide downward along the slide rail 2 in the tank body 1 until the material is compacted by the pressure cap 3. At this time, the pressure cap 3 separates the tank body 1 into a fermentation chamber and a pressure relief chamber. The gas generated by the raw materials in the fermentation chamber during the fermentation process is released into the pressure relief chamber through the one-way exhaust valve 5, thereby maintaining the stability of the pressure in the fermentation chamber and avoiding the increase of the pressure in the fermentation chamber. Even when the silage raw materials are less, they can be compacted by the pressure cap 3 to maintain a certain compaction density, and the reaction gas is effectively discharged by the one-way exhaust valve 5 to ensure the stability of the fermentation environment. That is, the utility model can provide a stable fermentation environment for different amounts of silage raw materials in the fermentation tank.

[0032] In one embodiment, a locking mechanism is further included, through which the pressing cover 3 can be locked on the slide rail 2, so that the pressing cover 3 can provide a greater pressure for the fermentation material, ensuring that the fermentation material is fully compacted.

Preferably, the positioning holes 9 are evenly arranged on the slide groove 7. When the gland 3 presses the fermentation material, the positioning pin is inserted from the through hole 8 and inserted into the positioning hole 9, so that the slider 6 is fixed on the slide rail 2, and the gland 3 is limited on the slide rail 2. The positioning pin is preferably threadedly connected with the through hole 8 and the positioning hole 9. Preferably, the aperture of the through hole 8 is consistent with that of the positioning hole 9, the slider 6 is perpendicular to the plane where the gland 3 body is located, the axis of the through hole 8 is parallel to the plane where the body is located, and the through hole 8 is located above the gland 3 body.

[0034] Of course, other forms of locking mechanisms may also be used, such as a clamping device fixedly provided on the pressure cover 3. After the pressure cover 3 compresses the fermentation material, it is clamped on the slide rail 2 through the clamping device, thereby achieving a fixed connection between the pressure cover 3 and the slide rail 2.

[0035] In one embodiment, two slide rails 2 are provided, and the slide rails 2 are arranged opposite to each other on the inner wall of the tank body 1, and both slide rails 2 are slidably connected with the gland 3, thereby ensuring the stability of the movement state of the gland 3. Of course, the slide rails 2 can also be provided in plurality according to actual conditions, and the gland 3 can be limited by the plurality of slide rails 2 together, so that the movement state of the gland 3 is more stable.

A hole cover that can be opened and closed is provided on the sampling hole 11. When sampling is required, the hole cover is opened, and the sampler is inserted into the fermentation chamber through the sampling hole 11 to take samples. After sampling, the hole cover is closed to achieve sealing of the sampling hole 11.

[0038] In one embodiment, a probe group 12 is also provided in the fermentation chamber. The probe group 12 includes a temperature probe and a humidity probe. The probe group 12 is fixed on the inner wall of the tank body 1. The temperature and humidity in the fermentation chamber can be detected through the probe group 12. The probe group 12 is preferably fixed on the bottom surface of the tank body 1.

[0039] In this embodiment, a display screen 13 is fixedly provided on the outer wall of the tank body 1, and is electrically connected to the probe group 12 through the display screen 13, so that the status information in the fermentation chamber, such as temperature, humidity information, etc., can be displayed through the display screen 13, so that the changes in internal temperature and humidity during the fermentation process can be observed in real time through the display screen 13.

[0040] In one embodiment, the pressure cover 3 is made of a transparent material, and the fermentation material can be observed through the pressure cover 3 from the outside of the tank body 1 to check whether the inside is moldy or discolored.
