Description

Technical Field

[0001] This invention belongs to the field of environmental protection technology promotion services, and relates to the technical field of harmless treatment of dead poultry, specifically a high-temperature harmless treatment equipment for dead poultry in farms. Background Technology

[0002] The rapid development of intensive poultry farming has made the harmless disposal of diseased and dead poultry a crucial link in preventing and controlling animal diseases, blocking the spread of pathogens, ensuring public health and safety, and promoting the sustainable development of the poultry industry. High-temperature rendering has become one of the mainstream processing methods because it can completely inactivate pathogens (such as avian influenza virus) and recover by-products such as oil and meat and bone meal.

[0003] Currently, most common high-temperature harmless treatment equipment for diseased and dead poultry adopts a single-shaft stirring type or static cooking tank structure. These devices generally suffer from the following technical shortcomings in actual operation:

[0004] The large amount of high-temperature waste gas (rich in water vapor and volatile substances) generated during the treatment process is usually discharged directly or after only simple treatment. The sensible and latent heat it carries is not effectively recovered, resulting in high energy consumption. Secondly, for materials such as poultry carcasses, which contain a large amount of feathers and fascia and are prone to sticking and clumping, single-shaft agitation is difficult to achieve all-round, high-intensity crushing and mixing. Material "clamping" or "scaling" phenomena are easily formed in the tank, which not only affects heat transfer efficiency but also leads to incomplete local treatment and poses biosafety risks. Summary of the Invention

[0005] The purpose of this invention is to provide a high-temperature harmless treatment device for diseased and dead poultry in farms, so as to solve the problems mentioned in the background art.

Detailed Implementation

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] Example 1: Please refer to Figures 1-3 and Figure 6 In this embodiment of the invention, a high-temperature harmless treatment device for dead poultry in a farm includes a base 1, and further includes:

[0051] The processing tank 2 is set above the base 1. Both ends of the processing tank 2 are open structures. The outer ends of the processing tank 2 are fixedly connected to the base 1 with support legs 3. The outer end of the processing tank 2 has a downward-facing discharge port 36 installed through at the bottom position, and a through exhaust pipe 30 is set at the top position.

[0052] A gradient heating structure is installed on the processing tank 2;

[0053] The capping assembly 4 is fixedly installed at both ends of the base 1;

[0054] A conveying mechanism is rotatably installed between the two sets of sealing assemblies 4. The conveying mechanism includes a conveying component for uniformly guiding the material from the front end to the end in the processing tank 2; and a dispersing component for continuously dispersing the material during the conveying process.

[0055] The drive assembly 6, which is fixedly installed on the base 1, is used to drive the guide assembly. It includes a support 25 fixedly installed on the base 1, a motor 26 fixedly installed on the top of the support 25, and a drive pulley 24 fixedly installed on the output shaft end of the motor 26.

[0056] And a feed assembly 5 that is fixedly installed on the periphery of the processing tank 2 near the front end.

[0057] During operation, the crushed diseased and dead poultry material enters the processing tank 2 through the feeding assembly 5. The motor 26 in the drive assembly 6 starts, driving the conveying mechanism via belt drive. The conveying assembly slowly and uniformly guides the material from the front end of the processing tank 2 to the discharge port 36 at the rear, ensuring sufficient residence time. Simultaneously, the gradient heating structure provides the processing tank 2 with stepped heat distributed from high to low, continuously heating the material. Through the combination of "uniform speed conveying" and "gradient heating," a stable environment is provided for the material, meeting the requirements of the heat treatment process (heating-constant temperature-cooling), solving the problems of uneven heating time and high energy consumption in traditional batch processing, and laying the foundation for continuous and efficient processing.

[0058] Example 2: Please refer to Figure 3 , Figure 5 and Figure 6 Based on Example 1, the sealing assembly 4 includes a sealing ring 18, which is fixedly installed at the end of the processing tank 2 via a flange. A rotatable turntable 20 is installed in the sealing ring 18 via a sealed rotating bearing 19.

[0059] The conveying assembly includes a conveying shaft 7 coaxially disposed in the processing tank 2, and a spiral blade 43 is provided on the outer periphery of the conveying shaft 7 located inside the processing tank 2.

[0060] When the two ends of the guide shaft 7 are fixed, they pass through the corresponding turntable 20. A driven pulley 22 is fixedly installed on the periphery of the guide shaft 7 at one end near the drive assembly 6. A belt 23 is installed between the driven pulley 22 and the drive pulley 24.

[0061] Motor 26 drives the guide shaft 7 and its spiral blade 43 to rotate via drive pulley 24, belt 23, and driven pulley 22. The spiral blade 43, as the main pushing component, continuously pushes the material in the discharge direction. This achieves the core function of axial material conveying, creating conditions for subsequent mixing and heat exchange.

[0062] Example 3: Please refer to Figure 2 , Figure 3 , Figure 5 and Figure 9 Based on embodiment 2, a cavity 44 is provided inside the guide shaft 7, and a copper coil 27 is fixedly installed in the cavity 44. Both ends of the copper coil 27 penetrate through the end of the guide shaft 7 to the outside of the guide shaft 7, and both ends of the copper coil 27 are coaxial with the guide shaft 7.

[0063] A rotating tube connector 28 is fixedly installed at one end of the copper coil 27 near the drive assembly 6. A first conduit 29 is connected to the end of the rotating tube connector 28 away from the copper coil 27. The first conduit 29 is rotatably connected to the copper coil 27 through the rotating tube connector 28.

[0064] A rotating pipe connector 32 is fixedly installed at the other end of the copper coil 27. The end of the rotating pipe connector 32 away from the copper coil 27 is connected to a second conduit 31. The end of the second conduit 31 away from the copper coil 27 is connected to the end of the exhaust pipe 30 away from the treatment tank 2.

[0065] The high-temperature exhaust gas generated during the treatment process is discharged from the exhaust pipe 30 and enters the copper coil 27 in the internal cavity 44 of the guide shaft 7 through the second conduit 31. As the exhaust gas flows through the copper coil 27, its heat is absorbed by the copper tube wall and conducted to the entire guide shaft 7, making it a huge "heat shaft". Finally, the exhaust gas is discharged through the first conduit 29.

[0066] This invention utilizes a rotating spindle as a heat exchange medium to achieve in-situ, efficient recovery of waste heat from exhaust gases. This recovered heat is directly used to heat the wet, cold materials in contact with the spindle, significantly improving the overall thermal efficiency of the system and solving the problem of high energy consumption caused by the direct emission of waste gas heat.

[0067] Example 4: Please refer to Figures 3-6 Based on Example 3, the dispersing component includes a motor 35 and four rotating shafts 21. The four rotating shafts 21 are rotatably mounted between two turntables 20, and the four rotating shafts 21 are arranged in a circumferential array about the guide shaft 7. Multiple sets of crushing components are arranged in an array along the length direction on the periphery of a pair of opposite rotating shafts 21, and multiple sets of centrifugal stirring components are arranged in an array along the length direction on the periphery of another pair of opposite rotating shafts 21.

[0068] After the four rotating shafts 21 are rotated through the turntable 20 at the corresponding positions, they are fixedly installed with synchronous pulleys 33, and synchronous belts 34 are installed between the four synchronous pulleys 33.

[0069] Motor 2 35 is fixedly mounted on the outer side of turntable 20 near synchronous pulley 33, and the output shaft end of motor 2 35 is fixedly connected to a synchronous pulley 33.

[0070] Motor 2 35 drives four rotating shafts 21, which are arranged in a circumferential array about the guide shaft 7, to rotate at high speed via synchronous belt 34. At the same time, since the rotating shafts 21 are mounted on a rotatable turntable 20, they also revolve around the guide shaft 7. The rotating shafts 21, which are equipped with pulverizing and centrifugal stirring components, form a complex planetary motion trajectory inside the tank.

[0071] Through a combination of high-speed rotation and revolution, the main material flow pushed by the spiral blade 43 is strongly intervened and cut, achieving global and high-intensity mixing and crushing of the material. This effectively breaks up clumps that may form due to material adhesion, increases the heat exchange area, and solves the problems of uneven mixing and dead zones that are easily generated in single-shaft mixing.

[0072] Example 5: Please refer to Figure 6 and Figure 7 Based on embodiment 4, the crushing assembly includes a first auger blade 37 and a second auger blade 38 fixedly mounted on the rotating shaft 21, with the first auger blade 37 and the second auger blade 38 rotating in opposite directions; it also includes a plurality of dispersing blades 39 fixedly mounted on the periphery of the rotating shaft 21, the plurality of dispersing blades 39 being arranged in a circumferential array about the axis of the rotating shaft 21, and the plurality of dispersing blades 39 being located in the middle position between the first auger blade 37 and the second auger blade 38.

[0073] The auger blades 37 and 38 on the rotating shaft 21 rotate in opposite directions, actively pushing the surrounding material towards the dispersing cutter 39 in the center. The dispersing cutter 39 shears and impacts the material under high-speed rotation. This design not only mixes the material but also achieves "active aggregation-centralized crushing," especially effective for tough parts of poultry such as fascia and connective tissue, resulting in higher crushing efficiency and further ensuring the uniformity of material particles, leading to more thorough subsequent heating.

[0074] Example 6: Please refer to Figure 6 and Figure 8 Based on Example 4, the centrifugal stirring assembly includes two symmetrically fixed hinge seats 40 on the periphery of the rotating shaft 21. The pins of the hinge seats 40 are parallel to the rotating shaft 21. A connecting rod 41 is fixedly connected to the periphery of the pins of the hinge seats 40. A scraper 42 is fixedly installed at the end of the connecting rod 41 away from the hinge seats 40. The side of the scraper 42 away from the connecting rod 41 is an arc surface, and the two sides of the scraper 42 are inclined surfaces, forming a shovel angle. When the connecting rod 41 is perpendicular to the rotating shaft 21, the rotation of the rotating shaft 21 drives the scraper 42 to remove the deposits on the inner wall of the treatment tank 2.

[0075] When the shaft 21 rotates at high speed, centrifugal force causes the hinged connecting rod 41 to throw the scraper 42 outward. The arc surface and shovel angle design of the scraper 42 can effectively scrape and treat materials that may adhere to the inner wall of the tank 2. When encountering hard objects, the hinged structure allows the scraper 42 to swing and avoid them. This design realizes the functions of stirring and self-cleaning. It can dynamically prevent materials from scaling on the tank wall, maintain the good heat transfer performance of the tank wall, and at the same time, its adaptive avoidance characteristics ensure operational stability, solving the problems of easy adhesion and difficult cleaning on the inner wall of traditional equipment.

[0076] Example 7: Please refer to Figure 10Based on embodiment 3, the feeding assembly 5 includes a hollow column 51 horizontally placed above the processing tank 2. A feed pipe 55 is fixedly installed through the bottom of the hollow column 51. The bottom end of the feed pipe 55 is fixedly connected through the processing tank 2. A feeding bin 45 is fixedly installed through the top of the hollow column 51. A feed inlet 47 is provided at the center of the top of the feeding bin 45. A guide pipe 48 is fixedly connected to the top of the feed inlet 47. The end of the guide pipe 48 away from the feed inlet 47 is connected to an external feeding device.

[0077] A preheating chamber 46 is provided in the feed hopper 45. The end of the first conduit 29 away from the copper coil 27 is fixedly connected to the preheating chamber 46 in a through manner, and the connection is located at the bottom of the preheating chamber 46. An exhaust pipe 2 49 and a drain pipe 2 50 are fixedly installed in a through manner around the feed hopper 45. The exhaust pipe 2 49 is located at the upper part, and the drain pipe 2 50 is located at the lower part.

[0078] A motor 54 is fixedly installed at one end of the hollow column 51. An installation roller 52 is rotatably installed between the two ends of the hollow column 51. The end of the installation roller 52 closest to the motor 54 rotates through the end of the hollow column 51 and is fixedly connected to the output shaft end of the motor 54. Multiple circumferentially arrayed feeding plates 53 are fixedly connected to the periphery of the installation roller 52. The end of the feeding plate 53 away from the installation roller 52 is an arc surface and slides in contact with the inner wall of the hollow column 51.

[0079] The exhaust gas from the copper coil 27 is introduced into the preheating chamber 46 of the feed hopper 45 through the first conduit 29 to preheat the freshly fed room-temperature material. After preheating, the exhaust gas is discharged from the exhaust pipe 49, and the condensate is discharged from the drain pipe 50. Simultaneously, the motor 54 drives the feeding plate 53 to rotate, achieving uniform and controllable quantitative feeding, and a dynamic seal is formed by the sliding contact between the feeding plate 53 and the inner wall of the hollow column 51. This setup achieves three-stage energy utilization (main heating - shaft heating - preheating). Preheating reduces the heat load of the material entering the main tank, and the dynamic seal reduces heat loss from the feed inlet, resulting in significant overall energy savings and improved working conditions.

[0080] Example 8: Please refer to Figure 1 and Figure 2 Based on Example 1, the gradient heating structure includes a cavity set in the processing tank 2, two heat insulation plates 56 are fixedly installed in the cavity, the two heat insulation plates 56 divide the cavity into three heating chambers 8, a temperature sensor is set on the inner side of the heating chamber 8, and the three heating chambers 8 are, from the front end to the back end of the processing tank 2, a high temperature zone, a medium temperature zone and a low temperature zone respectively.

[0081] The heating chamber 8 has an exhaust pipe 9 fixedly installed at the top. The three exhaust pipes 9 are connected to the gas collecting pipe 10. The gas collecting pipe 10 is also connected to the gas outlet pipe 11, which is connected to an external steam collection device.

[0082] A drain pipe 15 is fixedly installed through the heating chamber 8 at the lowest position. The three drain pipes 15 are connected to a water collection pipe 16. The water collection pipe 16 is also connected to a water guide pipe 17. The water guide pipe 17 is connected to an external water collection device.

[0083] An air inlet pipe 12 is fixedly installed through the bottom of the heating chamber 8. A flow valve is installed in the air inlet pipe 12. The three air inlet pipes 12 are connected to a branch pipe 13. The branch pipe 13 is also connected to a guide pipe 14. The guide pipe 14 is connected to an external steam supply device.

[0084] Steam enters three independent heating chambers 8 through the steam guide pipe 14, the branch pipe 13, and the inlet pipe 12. The temperatures of the three zones—high temperature, medium temperature, and low temperature—can be independently and precisely controlled by the flow valves on each inlet pipe 12 and the temperature sensors inside the heating chamber 8.

[0085] Condensate is collected and discharged through drain pipe 15, and exhaust gas is collected and discharged through exhaust pipe 9.

[0086] By using physical isolation and independent temperature control, a stable and controllable gradient temperature field is created along the axis of the equipment. This prevents the material from being locally overheated or underheated, improving processing efficiency while also avoiding energy waste.

[0087] Example 9: Based on Example 8, a control module is also included. This control module can be a programmable logic controller or an industrial computer. Its signal input terminal is electrically connected to temperature sensors (not shown in the figure) respectively disposed inside the three heating chambers 8, and its control output terminal is electrically connected to flow valves (not shown in the figure) respectively disposed on the three air inlet pipes 12.

[0088] During operation, the operator presets target temperature values ​​for the high-temperature, medium-temperature, and low-temperature zones in the control module according to process requirements. Temperature sensors inside each heating chamber 8 monitor the material temperature in its corresponding area in real time and feed the temperature signal back to the control module. The control module compares the received real-time temperature signal with the preset target temperature value, calculates control commands based on its built-in control algorithm (such as PID control, a mature existing technology), and outputs them to the flow valves on the corresponding air inlet pipes 12 to dynamically adjust the steam flow rate entering each heating chamber 8.

[0089] For example, when the temperature sensor feedback value in the high-temperature zone is lower than the set value, the control module increases the opening of the flow valve on the corresponding air intake pipe 12 in the high-temperature zone to increase the steam supply and raise the temperature; conversely, it decreases the opening. The control principles for the medium-temperature zone and the low-temperature zone are the same, and the control of the three zones is independent of each other.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
