Description

Technical Field

[0001] This invention relates to the field of straw degradation technology, and in particular to a treatment device for straw degradation. Background Technology

[0002] Straw degradation is the process by which straw undergoes microbial fermentation, and through the degradation action of special enzymes produced by microbial metabolism, its macromolecules such as cellulose, lignin, and hemicellulose are broken down into low-molecular-weight monosaccharides or oligosaccharides. The existing method of straw degradation involves placing shredded straw inside a fermentation tank, spraying fermentation liquid into the tank, and then subjecting the straw to anaerobic fermentation. This method has the following problems: 1. The crushed straw material is put into the fermentation box through the feed inlet. Since the feed inlet is in a one-way direction, the straw tends to accumulate below the feed inlet of the fermentation box, which affects the uniformity of the crushed straw fermentation. 2. After the crushed straw is put into the fermentation box, fermentation liquid needs to be sprayed into the fermentation box. Since the amount of straw put in and the amount of fermentation liquid sprayed should be mixed in proportion, the existing technology cannot make proportional adaptation. To address the above problems, we propose a treatment device for straw degradation. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a processing device for straw degradation. A moving push plate flattens the material, and the pressure change generated by the push plate's movement is converted into the force of a mixing claw mechanism, facilitating the mixing of the sprayed, pulverized straw. The amount of pulverized straw material is reflected in the change in gravity, thereby altering the height of the liquid-absorbing mechanism to ensure stable and sufficient absorption of the bacterial solution.

[0004] This invention provides a treatment device for straw degradation, comprising an anaerobic fermentation chamber and a storage tank. The storage tank is located on one side of the anaerobic fermentation chamber. A holding box is slidably connected inside the anaerobic fermentation chamber. The holding box is equipped with a leveling and mixing mechanism, which includes a push plate and a mixing claw mechanism. The push plate is movably located inside the holding box. A threaded rod is rotatably connected inside the holding box and threadedly connected to the push plate. A drive motor is fixedly connected to the holding box, and the output end of the drive motor is connected to the end of the threaded rod. A protective corrugated tube is sleeved on the surface of the threaded rod. Both ends of the protective corrugated tube are fixedly connected to the holding box and the push plate, respectively. The push plate has a hollow structure inside, and a conduit is connected to the hollow structure of the push plate. The other end of the conduit is connected to the protective corrugated tube. The mixing claw mechanism is rotatably located on the side of the push plate, and a connecting pipe is fixedly connected to the mixing claw mechanism. The other end of the connecting pipe is connected to the hollow structure of the push plate.

[0005] The storage tank is equipped with a liquid suction mechanism, which includes a suction tube and a telescopic column. The fixed end of the telescopic column is fixedly connected to the inner top wall of the storage tank, and a gas passage pipe is fixedly connected to the fixed end of the telescopic column. The other end of the gas passage pipe is fixedly connected to the bottom of the anaerobic fermentation chamber. The upper end of the suction tube is fixedly connected to the output end of the telescopic column. The anaerobic fermentation chamber is equipped with a liquid distribution plate. A liquid passage pipe is fixedly connected to the side end of the suction tube, and the other end of the liquid passage pipe is fixedly connected to the liquid distribution plate.

[0006] A further improvement of the present invention includes a mixing claw mechanism comprising a mixing claw and a sealing ring. The mixing claw is rotatably connected to one side of a push plate, and a fan blade is fixedly connected to the mixing claw. The sealing ring is rotatably fitted onto the mixing claw, and the fan blade is disposed inside the sealing ring. One end of a connecting pipe is connected to the hollow structure of the push plate, and the other end is connected to the side end of the sealing ring. A gas storage plate is fixedly connected to the push plate, and an air outlet pipe is fixedly connected to the side end of the sealing ring. The other end of the air outlet pipe is fixedly connected to the gas storage plate.

[0007] In a further improvement of the present invention, a limiting plate is fixedly connected inside the anaerobic fermentation box, and a limiting mechanism is fixedly connected to the lower end surface of the container, with one end of the limiting mechanism extending into the limiting plate.

[0008] Beneficial effects of the present invention: The present invention provides a treatment device for straw degradation: 1. The push plate moves under the drive of the screw rod, which can flatten the piled-up crushed straw. At the same time, the mixing claw mechanism on the side can turn the crushed straw during the movement to ensure that the material is loose and increase the contact area with the bacterial liquid. 2. The mixing claw mechanism is connected to the hollow structure of the push plate and has built-in fan blades. When the push plate moves, the gas inside the protective corrugated pipe is squeezed through, and the fan blades drive the mixing claw to rotate automatically, stirring the crushed straw after spraying the bacterial liquid. This design converts gas power into mechanical stirring force, without the need for an additional drive motor. It has a clever structure and can deeply turn the material. Third, the liquid suction mechanism adopts a linkage structure of telescopic column and liquid suction pipe. Furthermore, the liquid suction mechanism is connected to the anaerobic fermentation box, so that the liquid suction pipe can automatically adjust its position according to the amount of crushed straw to ensure stable absorption of bacterial liquid. Fourth, the protective corrugated pipe is sleeved on the surface of the threaded rod and connected to the hollow structure of the push plate. This not only protects the threaded rod from the corrosion of straw debris and corrosive liquids, but also serves as a gas delivery channel, achieving multiple uses in one piece.

The pump 31 is connected to the top of the anaerobic fermentation box 1.

[0014] In a further improvement of the present invention, the mixing claw mechanism 6 includes a mixing claw 10 and a sealing ring 11. The mixing claw 10 is rotatably connected to one side of the push plate 5. A fan blade 12 is fixedly connected to the mixing claw 10. The sealing ring 11 is rotatably fitted onto the mixing claw 10.

[0015] In a further improvement of the present invention, a limiting plate 17 is fixedly connected inside the anaerobic fermentation box 1, and a limiting mechanism 18 is fixedly connected to the lower end face of the holding box 3. The limiting mechanism 18 includes an electric telescopic rod 25 and an L-shaped push plate 26.

[0016] principle: In use, the crushed straw is fed into the holding box 3 through the feed inlet 29 and guided by the guide plate 30. After the material is fed in, the drive motor 16 is started to start the leveling operation. The drive motor 16 starts and drives the threaded rod to rotate. When the threaded rod rotates, it drives the push plate 5 to move horizontally. The push plate 5 flattens the crushed straw piled on the bottom of the holding box 3. When the push plate 5 moves horizontally, the protective corrugated pipe 7 is folded. The gas inside the protective corrugated pipe 7 is squeezed into the hollow structure of the push plate 5 and enters the gas storage plate 13 through the connecting pipe 19, the sealing ring 11, and the gas outlet pipe 24. During the flow of gas, the fan blade 12 is driven to rotate, which in turn drives the mixing claw 10 to rotate, stirring the crushed straw and preventing it from piling up and resulting in a small contact surface with the environment inside the anaerobic fermentation box 1.

[0017] When the crushed straw is put into the holding box 3, the weight of the straw compresses the spring telescopic rod 23 to retract, the holding box 3 moves down, and the gas inside the anaerobic fermentation box 1 below the holding box 3 is compressed and enters the fixed end of the telescopic column 15 through the gas pipe 20, which compresses the extended end of the telescopic column 15 to extend, thereby driving the liquid suction pipe 14 to move down, so as to facilitate the absorption of more bacterial liquid.

[0018] When the push plate 5 moves to the other end of the holding box 3, the drive motor 16 stops running, the pump 31 starts, and the bacterial liquid inside the storage tank 2 enters the liquid distribution plate 9 through the suction pipe 14 and the liquid passage pipe 21, and is sprayed out onto the crushed straw through the liquid distribution plate 9 for fermentation.

[0019] After the bacterial solution is sprayed, the pump 31 stops running, the drive motor 16 starts and reverses, driving the push plate 5 to reset, the protective corrugated pipe 7 extends, and the gas in the gas storage plate 13 enters the protective corrugated pipe 7 through the gas outlet pipe 24, the sealing ring 11, and the connecting pipe 19. During the flow of gas, the fan blade 12 rotates, thereby driving the mixing claw 10 to rotate, stirring the sprayed crushed straw and ensuring the fermentation and degradation effect.

Any person skilled in the art may make various modifications and alterations without departing from the spirit and scope of the present invention.
