Description

Technical Field

[0001] This utility model relates to the technical field of livestock and poultry manure recycling devices, and in particular to a livestock and poultry manure recycling drying device. Background Technology

[0002] The livestock and poultry manure recycling and drying device is a piece of equipment designed specifically for treating livestock and poultry breeding waste. It can convert manure with high water content into reusable organic fertilizer or energy raw materials, combining environmental protection and resource utilization functions.

[0003] In the prior art, such as Chinese Publication No. CN220383920U, a utility model discloses a cow manure reprocessing and recycling system, relating to the field of livestock and poultry manure treatment and utilization technology. The system includes a cowshed, a manure collection tank on one side of the cowshed, a homogenizing tank connected to another side of the manure collection tank, an anaerobic fermentation tank installed on one side of the homogenizing tank, and a dry-wet separator connected to the output port of the anaerobic fermentation tank. A biogas slurry tank is located on one side of the dry-wet separator. This utility model, with the addition of an auxiliary material trough, a heat exhaust pipe, an auger, a mixing chamber, and a double-chamber storage bin, allows for the addition of organic auxiliary materials to the solid cow manure that needs to be made into organic fertilizer after the cow manure reprocessing and recycling process. This enables the dried and mixed cow manure to be directly transported to farmland or used for earthworm farming, mushroom cultivation, grasshopper farming, and other multi-channel utilization modes, improving the functionality of the recycling system, reducing the labor intensity of subsequent workers, saving time and effort, and being convenient to use.

[0004] While the above-mentioned solutions have the advantages mentioned above, their disadvantages are as follows: the livestock and poultry manure recycling drying device lacks a multi-stage drying and crushing structure, making it difficult to fully dry the manure, resulting in high residual moisture, easy bacterial growth, and affecting subsequent processing and utilization. Furthermore, large particles of manure cannot be effectively crushed, leading to uneven drying, reduced device efficiency, increased energy consumption, and potential equipment damage. The lack of shock-absorbing and buffering structures in the livestock and poultry manure recycling drying device results in severe vibration and shaking during operation. This not only generates significant noise, affecting the surrounding environment, but also loosens equipment connections, shortening its service life. Simultaneously, the vibration causes uneven distribution of manure, further reducing the drying effect and quality. In addition, strong mechanical impacts may pose safety hazards, such as parts falling off, posing a threat to workers. Utility Model Content

[0005] The purpose of this invention is to provide a drying device for the reuse of livestock and poultry manure. This invention features a multi-stage, multi-stage drying and crushing structure, which ensures that the manure is thoroughly dried with low residual moisture, minimizing the risk of bacterial growth and facilitating subsequent processing and utilization. Large manure particles can be effectively crushed, achieving uniform drying, improving device efficiency, reducing energy consumption, and extending equipment life. The device is designed with a shock-absorbing and buffering structure, resulting in minimal vibration and noise during operation, minimizing the impact on the surrounding environment. The connection parts of the equipment are less prone to loosening, extending its service life. The low vibration ensures uniform manure distribution, resulting in better drying effect and higher quality. In addition, it reduces mechanical impact, avoids safety hazards such as parts falling off, and effectively protects the safety of workers.

Two transmission belts 8 are driven to the outer surfaces of the multiple second transmission wheels 17. When the motor 14 is turned on, the output shaft of the motor 14 drives the two gears 15 to rotate. This drives the two crushing rollers 16 to rotate, the gear 15 drives the rotating shaft 18 to rotate, which in turn drives the two second transmission wheels 17 to rotate, and through the two transmission belts 8 drives the multiple first transmission wheels 3 to rotate, which in turn drives the upper and lower metal mesh conveyor belts 2 to rotate synchronously in the same direction, opening the multiple drying heating tubes 6 inside the box 1. The livestock and poultry manure to be dried enters the box 1 through the feed plate 4, and is initially heated and dried by the two upper drying heating tubes 6 at the upper metal mesh conveyor belt 2. It then moves with the metal mesh conveyor belt 2 to one end and falls between the two crushing rollers 16. The two crushing rollers 16 rotate to crush the livestock and poultry manure. After crushing, the livestock and poultry manure falls downward to the lower metal mesh conveyor belt 2 and is then subjected to secondary heating and drying by the two lower drying heating tubes 6. It then moves with the metal mesh conveyor belt 2 to one end and falls through the discharge port 20.

[0027] Furthermore, such as Figures 1 to 4 As shown, a frame 19 is fixedly installed on the outer surface of the housing 1. The frame 19 is fixedly connected to the outer surface of the motor 14, and the frame 19 fixes the motor 14.

[0028] Furthermore, such as Figures 1 to 4 As shown, two connecting plates 7 are fixedly installed on the outer surface of the box 1. Two limiting rods 13 are slidably connected to the inner surface of the two connecting plates 7. The connecting plates 7 on both sides cooperate with the multiple limiting rods 13 to limit the box 1.

[0029] Furthermore, such as Figures 1 to 4 As shown, a base plate 11 is fixedly installed on the bottom outer surface of multiple limit rods 13, and two fixing brackets 9 are fixedly installed on the outer surface of the base plate 11. The two fixing brackets 9 are fixedly connected to the multiple limit rods 13 respectively, and the two fixing brackets 9 install the multiple limit rods 13.

[0030] Furthermore, such as Figures 1 to 4 As shown, multiple shock-absorbing dampers 10 are fixedly installed on the outer surface of the base plate 11. The multiple shock-absorbing dampers 10 are fixedly connected to the bottom outer surface of the two connecting plates 7 respectively.

[0031] Furthermore, such as Figures 1 to 4 As shown, multiple shock-absorbing dampers 10 are fixedly provided with buffer springs 12 on their outer surfaces. The multiple buffer springs 12 are fixedly connected to the bottom outer surfaces of the two connecting plates 7 respectively. The multiple buffer springs 12 undergo elastic deformation to buffer the vibration and shaking of the box 1.

[0032] Furthermore, such as Figures 1 to 4 As shown, a feed plate 4 is fixedly installed on the outer surface of the box 1, and multiple breathable filter plates 5 are movably installed on the outer surface of the box 1.

Multiple drying heating tubes 6 inside the box 1 are opened. The livestock and poultry manure to be dried enters the box 1 through the feed plate 4. It is initially heated and dried by the two drying heating tubes 6 on the upper metal mesh conveyor belt 2, and then falls between the two crushing rollers 16 as it moves along the metal mesh conveyor belt 2. The crushing roller 16 rotates to crush the livestock and poultry manure. After crushing, the manure falls downward onto the lower metal mesh conveyor belt 2 and is then heated and dried by the two lower drying heating pipes 6. It then moves with the metal mesh conveyor belt 2 to one end and falls through the discharge port 20. The water vapor generated by the heated and dried manure is discharged through multiple breathable filter plates 5. When the device is drying the livestock and poultry manure, it causes vibration and shaking of the box body 1. Multiple shock-absorbing dampers 10 extend and retract to reduce the vibration and shaking of the box body 1. At the same time, multiple buffer springs 12 undergo elastic deformation to buffer the vibration and shaking of the box body 1. The connecting plates 7 on both sides, together with multiple limiting rods 13, limit the box body 1.
