Description

Technical Field

[0001] The present invention relates to the technical field of fermentation equipment, and in particular to an environmentally friendly feed fermentation device and a use method thereof. Background Art

[0002] Biofeed is an animal feed or feed raw material prepared by bio-fermentation of feed substrates based on microbial fermentation technology. The prepared bio-fermented feed improves the utilization rate of roughage and reduces the waste of feed raw materials. Bio-feed fermentation can not only remove anti-nutritional factors in the raw materials, improve the palatability and digestibility of the feed, but also convert unconventional raw materials into feed raw materials that can be digested and absorbed by animals, effectively reducing or even replacing the use of antibiotics in feed and breeding processes.

[0003] During the fermentation process, biological feeds (such as straw and grass) need to be compacted layer by layer. The core purpose is to create a strict anaerobic environment and expel air between cells. This operation directly affects the success of fermentation and feed quality. However, existing compaction operations are all performed manually, and each layer of feed is manually flattened and compacted. During the compaction process, the compaction force cannot be guaranteed, resulting in different amounts of air expelled from each layer of feed. There are also differences in the amount of feed in each layer, resulting in different levels of fermentation in each layer. Summary of the Invention

A pressure sensor is installed at the air inlet of the hydraulic cylinder 3. The pressure sensor detects that the pressing mechanism 2 applies the same pressure to each layer of feed, thereby ensuring that the compaction degree of each layer of feed is the same; the pressing mechanism 2 includes a pressing seat 21 with a hollow structure, which is used to compact the feed in the fermentation tank 1 layer by layer. A feeding port 29 is provided on the pressing seat 21, and the feeding port 29 can be opened and closed. The feed raw materials enter the pressing seat 21 through the feeding port 29. A plurality of discharge ports 22 are evenly arranged on the side of the pressing seat 21. In this embodiment, there are four discharge ports 22. The discharge port 22 is slidably connected to a valve plate 23 that can be raised and lowered. The cross-section of the valve plate 23 is an L-shaped structure. The valve plate 23 is used to close the discharge port. 22 is closed, and the discharge port 22 is closed when the valve plate 23 rises, and the discharge port 22 is opened when the valve plate 23 falls; and a spraying assembly 25 is provided in the pressing seat 21, and the spraying assembly 25 is located at the top position in the pressing seat 21, and the spraying assembly 25 is used to evenly spray the fermentation agent onto the feed raw material; in specific implementation: first, the discharge port 22 is closed, and the crushed feed raw material is conveyed into the pressing seat 21 through the feed port 29, and then the fermentation agent is evenly sprayed onto the feed raw material through the spraying assembly 25. After the two are fully mixed, the discharge port 22 is opened, and the mixed feed is discharged from the discharge port 22 and falls into the interior of the fermentation tank 1. Then, the hydraulic cylinder 3 drives the pressing seat 21 to descend, compacts the feed, and discharges the air in the feed. The above actions are repeated, and the feed is stacked from bottom to top in the fermentation tank 1 to multiple layers, compacted in turn, and the compaction strength is the same each time to ensure that the air is discharged to the same degree in each layer of feed.

[0025] like Figure 5-Figure 6As shown, the bottom of the pressing seat 21 is rotatably connected to a rotating disk 24, and the rotating disk 24 contacts the bottom of the pressing seat 21, and a rotating motor 241 for driving the rotating disk 24 to rotate is fixedly installed on the pressing seat 21.

The valve plate 23 is driven up and down by the lifting cylinder 26, thereby controlling the switch of the discharge port 22; wherein, the spraying assembly 25 includes a ring-shaped liquid separation seat 253, the liquid separation seat 253 is fixedly installed at the top position inside the material pressing seat 21, and a plurality of spray pipes 251 are evenly fixedly connected to the side of the liquid separation seat 253, and a plurality of nozzles are provided on the lower surface of the spray pipe 251. A liquid inlet interface 252 is provided, which is connected to an external pipeline. The fermentation agent enters the liquid separation seat 253 through the liquid inlet interface 252. The liquid separation seat 253 evenly transports the fermentation agent to each spraying pipe 251, and then sprays it onto the feed raw materials. In specific implementation: when the feed raw materials enter the pressing seat 21 from the feed port 29, the rotating motor 241 drives the rotating disk 24 to rotate slowly, so that the feed is evenly distributed in the rotating disk 24, and at the same time, the spraying assembly 25 sprays the fermentation agent on the surface of the feed, so that the fermentation agent and the feed raw materials are fully mixed until the feed raw materials fill the pressing seat 21, and then the lifting cylinder 26 drives the valve plate 23 to descend and open the discharge port 22, and then the rotating motor 241 drives the rotating disk 24 to rotate at a high speed. The feed raw materials are discharged from the discharge port 22 under the action of centrifugal force and fall into the fermentation tank 1, and then the lifting cylinder 26 drives the valve plate 23 to rise and close the discharge port 22, and the hydraulic cylinder 3 drives the pressing seat 21 to descend to compact the feed.

[0026] Preferably, the lower surface of the pressing seat 21 and the lower surface of the valve plate 23 are both fixedly connected with pressing plates 210 of mutually matching shapes, so as to facilitate better compaction of the feed.

[0027] Preferably, a plurality of friction strips 243 and stirring columns 242 are provided on the surface of the rotating disk 24, wherein the stirring columns 242 and the connecting rod 262 do not interfere with each other.

[0031] In this embodiment, the feed raw materials are first conveyed into the pressing seat 21, and then the feed raw materials are fully mixed with the fermentation agent and dropped into the fermentation tank 1, thereby ensuring that the amount of feed in each layer is the same. The feed is compacted by the pressing seat 21, and the compaction strength is the same each time, so that the degree of air discharge from each layer of feed is the same.

[0032] This embodiment also discloses a method for using the environmentally friendly feed fermentation device. Based on the above fermentation device, the method includes the following steps: Step 1: The crushed feed material is loaded into the press seat 21 from the feed inlet 29.

When the lifting ring 261 descends, the valve plate 23 is driven downward to open the discharge port 22. Then, the rotating motor 241 drives the rotating disk 24 to rotate at high speed. Under the action of centrifugal force, the feed is discharged from the discharge port 22 and falls into the fermentation chamber 4. Step 3: After the feed is discharged, the lifting cylinder 26 drives the valve plate 23 to rise and reset, and the vibration motor 7 vibrates the fermentation tank 1 to make the feed evenly distributed in the fermentation tank 1. Then the hydraulic cylinder 3 drives the pressing mechanism 2 to descend to compact the feed. The pressed filtrate flows into the filtrate chamber 5 and is finally discharged from the liquid outlet pipe 8. Step 4: Repeat the above steps until multiple layers of feed are loaded into the fermentation tank 1 and compacted.
