Ultimately, the carcasses are transformed into usable resources or safely landfilled. This technology has the dual functions of resource utilization and environmental protection and is an important means of modern livestock waste management.
[0003] In existing technologies, the pulverization and degradation of livestock and poultry carcasses for harmless treatment mostly involves adding the pulverized carcasses into a degradation tank for degradation and disinfection. However, during the process of adding the carcasses to the degradation tank, large-scale feeding can lead to localized accumulation within the tank, resulting in insufficient heating efficiency for some of the pulverized carcasses. This causes hot and cold spots to appear inside the tank, and temperature fluctuations can cause instability in the fermentation process of the pulverized carcasses, affecting the quality of organic fertilizer. Therefore, this utility model provides a device for the pulverization, degradation, and harmless treatment of livestock and poultry carcasses. Utility Model Content

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0018] like Figures 1 to 5 As shown, this utility model provides a technical solution: a device for the pulverization, degradation, and harmless treatment of livestock and poultry carcasses, including a degradation tank 1. A threaded conveyor 2 is provided on the side of the degradation tank 1. A feed pipe 3 is fixedly connected to the output end of the threaded conveyor 2. The end of the feed pipe 3 away from the threaded conveyor 2 is fixedly connected to the degradation tank 1. A uniform feeding mechanism 4 is provided on the top of the degradation tank 1. An anti-clogging mechanism 5 is provided on the top of the threaded conveyor 2. The uniform feeding mechanism 4 includes a rotating rod 41 disposed inside the degradation tank 1. Four connecting rods 42 are fixedly connected at equal intervals to the top of the rotating rod 41. A hollow tube 43 is fixedly connected to the end away from the rotating rod 41. Three guide plates 44 are fixedly connected at equal intervals on the side of the hollow tube 43. Guide plates 45 are fixedly connected between the three guide plates 44. A partition 46 is fixedly connected inside the degradation tank 1. The rotating rod 41 is rotatably connected to the partition 46. The top surfaces of the guide plates 44 and 45 are both inclined. The three guide plates 45 are fan-shaped. A motor 47 is fixedly installed at the bottom inside the degradation tank 1. The bottom end of the rotating rod 41 passes through the partition 46. The end of the rotating rod 41 that passes through the partition 46 is fixedly connected to the output shaft of the motor 47.
[0019] Through the above technical solution, guide plate 1 44 and guide plate 2 45 together form a three-stage material distribution structure. When the crushed poultry and livestock carcasses enter the system through the feed pipe 3 and fall downwards, motor 1 47 starts and drives partition 46 to rotate. This causes partition 46 to drive hollow tube 43 to rotate through connecting rod 42, which in turn drives hollow tube 43, guide plate 1 44, and guide plate 2 45 on connecting rod 42 to rotate. Some of the crushed residue will directly enter hollow tube 43, then pass down along hollow tube 43 and settle to the middle area of degradation tank 1. At the same time, the crushed residue near the side wall of hollow tube 43 will first fall onto guide plate 2 45. With the help of the tilt angle of guide plate 2 45, these residues are guided to the transition area between the center and the tank wall inside degradation tank 1, thereby realizing the supplementary feeding of the central area of degradation tank 1. The crushed residue far from the hollow tube 43 falls onto the guide plate 44. The guide plate 44, with its specific tilt angle and surface texture, further guides these residues to the area near the inner wall of the degradation tank 1. In this way, the hollow tube 43 and the guide plate 44, together with the guide plate 45, work together to ensure that the crushed poultry and livestock carcasses are evenly distributed inside the degradation tank 1, avoiding local accumulation. Compared with the traditional single feeding method, this three-stage feeding structure significantly improves the uniformity of feeding. It can prevent hot and cold spots from appearing inside the degradation tank 1 due to local accumulation when feeding in large quantities, ensuring that the heating rate of all raw materials is kept within the design requirements, avoiding the problem of substandard high-temperature sterilization due to insufficient temperature, thereby improving the efficiency and safety of the overall degradation treatment.
[0020] Specifically, such as Figure 1 , Figure 2 as well as Figure 5As shown, the anti-clogging mechanism 5 includes a fixed pipe 51 fixedly connected to the top of the threaded conveyor 2. A fixed cover 52 is fixedly connected to the end of the fixed pipe 51 away from the threaded conveyor 2. A motor 53 is fixedly installed on the top of the fixed cover 52. A drive pulley 54 and a driven pulley 55 are rotatably connected inside the fixed cover 52. The output shaft of the motor 53 passes through the fixed cover 52 and is fixedly connected to the drive pulley 54. A rotating shaft 56 is rotatably connected inside the fixed pipe 51. The rotating shaft 56 is fixedly connected to the conveying rod inside the threaded conveyor 2. Two limiting plates 57 are symmetrically fixedly connected to the surface of the rotating shaft 56. Two limiting grooves 58 are symmetrically opened in the middle of the driven pulley 55. Both limiting plates 57 are slidably connected to the limiting grooves 58. The driving pulley 54 and the driven pulley 55 are both fitted with belts. A fixed cylinder 59 is fixedly connected to the side of the fixed cover 52 away from the fixed tube 51. A sliding plate 510 is slidably connected inside the fixed cylinder 59. One end of the rotating shaft 56 is rotatably connected to the sliding plate 510. Two electric telescopic rods 511 are symmetrically fixedly installed on the side of the fixed cylinder 59 away from the fixed cover 52. The movable ends of the two electric telescopic rods 511 pass through the fixed cylinder 59 and are fixedly connected to the sliding plate 510.
[0021] Through the above technical solution, after the driving pulley 54 starts to rotate, it drives the driven pulley 55 to rotate synchronously via the belt. As the driven pulley 55 moves, the mutual cooperation between the limiting plate 57 and the limiting groove 58 generates a constraint force, causing the rotating shaft 56 to be driven and generate continuous rotational motion. The rotation of the rotating shaft 56 further drives the conveying rod inside the threaded conveyor 2 to rotate synchronously, thereby realizing the continuous conveying of the crushed poultry and livestock carcasses along the inner wall of the threaded conveyor 2. If the crushed poultry and livestock carcasses cause local blockage due to adhesion to the inner wall of the threaded conveyor 2, the two electric telescopic rods 511 are activated. The movable end of the electric telescopic rods 511 retracts rapidly, causing the sliding plate 510 to slide away from the driven pulley 55 inside the fixed cylinder 59. This sliding action drives the rotating shaft 56 to move away from the fixed pipe 51. The sliding plate 510 moves horizontally, causing the conveying rod inside the threaded conveyor 2 to mechanically pry the blocked area. Subsequently, the movable end of the sliding plate 510 returns to its original position under the action of a spring or hydraulic reset device, pushing the rotating shaft 56 back to its initial position, enabling it to reciprocate inside the threaded conveyor 2. Even when the sliding plate 510 intervenes and moves horizontally, the driven pulley 55 continues to drive the rotating shaft 56 to rotate through the constraint of the limiting plate 57 and the limiting groove 58. In this way, the conveying rod maintains its rotation state while reciprocating and sliding, which can apply shearing and frictional forces to the blocked area in multiple directions, significantly improving the unblocking efficiency and preventing secondary blockages. This enables the threaded conveyor 2 to quickly unblock blockages while continuously conveying crushed poultry and livestock carcasses, ensuring the efficient and stable operation of the entire conveying system.
[0022] Specifically, such as Figure 1 As shown, the degradation tank 1 is equipped with a control panel, which is electrically connected to motor 47, motor 53 and electric telescopic rod 511.
[0023] Through the above technical solution, the control panel can control the opening and closing of motor 47, motor 53 and electric telescopic rod 511.
[0024] In operation, motor 53 is started, driving the drive pulley 54 to rotate. The rotation of the drive pulley 54, via the belt, drives the driven pulley 55 to rotate. This, in turn, through the engagement of the limiting plate 57 and the limiting groove 58, drives the rotating shaft 56 to rotate, thereby rotating the conveyor rod inside the threaded conveyor 2. This facilitates the transport of the pulverized livestock carcasses inside the threaded conveyor 2. When the pulverized livestock carcasses adhere to the inner wall of the threaded conveyor 2, causing a blockage, the movable ends of the two electric telescopic rods 511 retract. This causes the sliding plate 510 to slide away from the driven pulley 55 within the fixed cylinder 59, thus driving the rotating shaft 56 to slide away from the fixed pipe 51. Subsequently, the movable end of the sliding plate 510 resets, pushing the rotating shaft 56 back to its original position. This allows the rotating shaft 56 to drive the conveyor rod to reciprocate within the threaded conveyor 2, scraping away the pulverized livestock carcasses from the inner wall of the threaded conveyor 2, achieving an automatic unblocking effect. The pulverized livestock carcasses then enter the system through the discharge pipe 3 and fall downwards. When the material falls, motor 47 starts, driving partition 46 to rotate. This causes partition 46 to rotate hollow tube 43 via connecting rod 42, which in turn rotates hollow tube 43, guide plate 44, and guide plate 45 on connecting rod 42. Some of the crushed residue will directly enter hollow tube 43, then pass down along hollow tube 43 and settle to the middle area of degradation tank 1. At the same time, the crushed residue near the side wall of hollow tube 43 will first fall onto guide plate 45. With the help of the tilt angle of guide plate 45, these... The residue is guided to the transition zone between the center and the wall inside the degradation tank 1, thereby supplementing the central area of the degradation tank 1. The crushed residue far from the hollow tube 43 falls onto the guide plate 44. The guide plate 44, through its specific tilt angle and surface texture, further guides these residues to the area near the inner wall of the degradation tank 1. In this way, the hollow tube 43 and the guide plate 44 work together with the guide plate 45 to ensure that the crushed poultry and livestock carcasses are evenly distributed inside the degradation tank 1.
