[0003] In existing technologies, oat straw is usually crushed separately using a crushing device and then transferred to a fermentation device for fermentation. The two processes are completed independently, but efficiency is reduced because the crushed oat straw needs to be transferred. Utility Model Content

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] A fermentation device for treating oat straw and waste residue for saline-alkali land treatment includes a crushing chamber 1 and a fermentation tank 2 fixedly connected to the lower end of the crushing chamber 1; the oat straw is first crushed in the crushing chamber 1, and then the residue falls directly into the fermentation tank 2 below for fermentation.

[0024] The crushing chamber 1 is provided with a hollow crushing cavity 3. The upper end of the crushing chamber 1 is provided with a feed inlet 4 that communicates with the crushing cavity 3. The crushing chamber 1 is equipped with a set of feed rollers 5 near the feed inlet 4 and a set of crushing blades 6 located below the set of feed rollers 5. Oat straw is fed into the upper end of the set of feed rollers 5 through the feed inlet 4, conveyed downward by the set of feed rollers 5, and then crushed by the set of crushing blades 6.

[0025] The fermentation tank 2 has a hollow fermentation chamber 8. The lower end of the crushing chamber 3 is connected to the fermentation chamber 8 through a feeding port 7. The fermentation chamber 8 is equipped with a stirring mechanism, a temperature control component, and a humidity control component. The upper end of the fermentation tank 2 has a microbial inlet 12 connected to the fermentation chamber 8, and the lower end of the fermentation tank 2 has a discharge port 13 connected to the fermentation chamber 8. The discharge port 13 is fitted with an openable cover 14. The crushed oat straw residue falls into the fermentation chamber 8 through the feeding port 7, and then the microbial inoculum for fermentation is added through the microbial inlet 12. During fermentation, the stirring mechanism stirs the mixture to ensure even distribution of the microbial inoculum and aerates it to prevent localized anaerobic conditions. The temperature and humidity are controlled by the temperature and humidity control components. After fermentation, the lower cover 14 is opened, and the material is discharged through the discharge port 13. During each fermentation, the material does not completely fill the fermentation chamber 8; optimally, it is controlled to fill the fermentation chamber 8 to 2 / 3 of its capacity.

[0026] This invention integrates oat straw crushing and fermentation equipment, thereby avoiding the transfer between the two processes, saving the transfer time of oat straw residue, and thus improving work efficiency.

[0027] In a preferred embodiment, the feed roller group 5 includes two parallel feed rollers 5 that are installed and rotate within the crushing chamber 3. The two feed rollers 5 are driven to rotate by a first motor, and the two feed rollers 5 rotate in opposite directions.

[0028] The oat straw fed from the inlet is gripped and conveyed downwards by two counter-rotating feed rollers 5.

[0029] In a preferred embodiment, the pulverizing blade assembly includes two pulverizing blades 6 rotatably mounted within the pulverizing chamber 3. The pulverizing blades 6 are horizontally arranged and staggered. The pulverizing blades 6 are driven to rotate by a second motor. The pulverizing blades 6 are mounted and rotated within the pulverizing chamber 3 via a rotating shaft. A first pulley is fixedly mounted on the rotating shaft. A second motor is mounted on the outer wall of the pulverizing chamber 1, and a second pulley is fixedly mounted at the output end of the second motor. The second pulley and the first pulley are connected by a transmission belt.

[0030] The oat straw is shredded using the shredder 6.

[0031] In a preferred embodiment, the stirring mechanism includes a main shaft 9 that is horizontally disposed and rotates within the fermentation chamber 8. The main shaft 9 is driven to rotate by a third motor 11, and a plurality of stirring rods 10 are provided on the main shaft 9.

[0032] The third motor 11 drives the main shaft 9 to rotate, thereby driving several stirring rods 10 to tumble and stir the material in the fermentation chamber 8.

[0033] In a preferred embodiment, the temperature control component includes a heating wire embedded in the stirring rod 10 and a temperature sensor 15 embedded in the main shaft 9.

[0034] The real-time temperature of the material is monitored by temperature sensor 15. When the temperature is low, the material is heated by heating wire. When the temperature is sufficient, the heating is stopped.

[0035] In a preferred embodiment, the humidity control component includes a humidity sensor 16 embedded in the main shaft 9 and a plurality of spray heads 17 disposed at the upper end of the fermentation chamber 8. The upper end of the fermentation chamber 8 is provided with an installation groove, and the spray heads 17 are disposed in the installation groove.

[0036] The humidity sensor 16 monitors the real-time humidity of the material. When the humidity is low, water is sprayed through the spray head 17. When the humidity is sufficient, the water spraying stops.

[0037] In a preferred embodiment, the fermentation chamber 8 has a circular cross-section, and the end of the stirring rod 10 is positioned close to the inner wall of the fermentation chamber 8.

[0038] This setting reduces dead corners in the fermentation chamber 8, allowing the stirring rod 10 to tumble and stir all materials as much as possible.

[0039] In a preferred embodiment, the inner wall of the fermentation chamber 8 is provided with a corrosion-resistant and heat-insulating coating, including an epoxy glass flake anti-corrosion layer connected to the inner wall of the fermentation chamber 8, an aerogel polyurethane heat-insulating layer disposed on the surface of the epoxy glass flake anti-corrosion layer, and a fluorocarbon resin wear-resistant sealing layer disposed on the surface of the aerogel polyurethane heat-insulating layer.
