Description

Technical Field

[0001] This application relates to the field of organic fertilizer preparation technology, and in particular to an environmentally friendly organic fertilizer preparation device. Background Technology

[0002] Currently, with the development of large-scale and intensive modern livestock and poultry farming, the resource utilization of livestock and poultry manure has become one of the important directions for agricultural waste treatment. It can not only effectively reduce environmental pollution risks but also improve soil structure and enhance soil fertility, possessing significant ecological and economic value. In practical engineering applications, the organic fertilizer preparation process typically involves uniformly collected livestock and poultry manure being conveyed through a conveying system into a high-pressure belt filter press for mechanical filtration to achieve preliminary dehydration and form a solid filter cake with low moisture content. Subsequently, this filter cake material is transported to a low-temperature drying device for further drying to reduce its moisture content and improve storage stability, ultimately obtaining a dry-based organic fertilizer product.

[0003] In existing technologies, the drying treatment of organic solid materials after pressure filtration typically employs low-temperature drying equipment to avoid the damage to the active components of organic matter caused by high temperatures. This type of equipment is mostly based on hot air circulation or dehumidification and condensation principles. By constructing a relatively closed drying environment, it achieves continuous evaporation and removal of moisture within a low temperature range. Its basic working mechanism is based on utilizing the convective heat transfer between the airflow and the material surface to provide the latent heat of vaporization, while simultaneously relying on the diffusion and migration of moisture from the material's internal pore structure to the surface, thereby achieving overall dehydration. Existing equipment mostly adopts a continuous material-laying structure and controls the material layer thickness and airflow direction (e.g., vertical penetration or horizontal flow) to maintain relatively stable operating conditions during the drying process.

[0004] However, in practical applications, when livestock and poultry manure enters the conveying mechanism of the low-temperature drying equipment, uneven spreading due to random accumulation is inevitable. This can easily lead to short-circuiting of the airflow, causing excessive airflow in some areas, resulting in localized over-drying or even surface crusting. Once surface crusting occurs, this crust significantly hinders the continued outward diffusion of internal moisture, further reducing drying efficiency in the later stages. Simultaneously, airflow obstruction creates long-term high-humidity stagnation zones, making it difficult for moisture to drain effectively, resulting in significant uneven drying. Furthermore, high-moisture-content livestock and poultry manure easily adheres to the conveying mechanism, causing blockages and structural obstruction of the airflow channels. This hinders effective drying of the manure and severely affects the consistency and stability of organic fertilizer quality. Summary of the Invention

[0005] This application provides an environmentally friendly organic fertilizer preparation device. This device can evenly spread, prevent blockage during transport, enhance airflow and regulate mass transfer of livestock and poultry manure during the low-temperature drying process, effectively avoiding airflow short-circuiting, surface crusting and localized moisture retention, thereby significantly improving the drying efficiency of organic fertilizer and the consistency of product quality.

[0006] This application provides an environmentally friendly organic fertilizer preparation device, which adopts the following technical solution: An environmentally friendly organic fertilizer preparation device includes a shell, a conveying mechanism, and an airflow control mechanism. The shell houses a drying chamber and an equipment chamber. The conveying mechanism is located within the drying chamber, and the airflow control mechanism is located within the equipment chamber. The device is characterized by: A controller is provided on the housing; The transmission mechanism includes a frame, a feeding assembly, and an air injection assembly. The frame is located inside the drying chamber. Both the feeding assembly and the air injection assembly are located on the frame. The air injection assembly is located on one side of the feeding assembly. The feeding assembly is used to receive and transport livestock and poultry manure. The air injection assembly is used to transport airflow and make the airflow act on the livestock and poultry manure to promote the turning and drying of the manure. The feeding assembly includes a first motor, a drive shaft, a driven shaft, and a conveyor. The first motor is fixed on the frame and electrically connected to the controller. The drive shaft is rotatably mounted on the frame, and the driven shaft is movably mounted on the frame. The drive shaft is fixedly connected to the output end of the first motor, and the conveyor is wound around both the drive shaft and the driven shaft. The conveyor includes a first belt, a second belt, a first braided belt, and a second braided belt. The first belt and the second belt are both wound around the drive shaft and the driven shaft. The first braided belt and the second braided belt are disposed between the first belt and the second belt. One end of the first braided belt is connected to the first belt, and the other end of the first braided belt is connected to the second belt. One end of the second braided belt is connected to the first belt, and the other end of the second braided belt is connected to the second belt. The first braided belt overlaps the second braided belt, and the first braided belt and the second braided belt are arranged in a crisscross pattern. Multiple sets of the first braided belt and the second braided belt are provided, and the multiple sets of the first braided belt and the second braided belt are arranged at equal intervals along the length direction of the first belt.

[0007] By adopting the above technical solution, and by setting a first belt, a second belt, and multiple sets of first and second woven belts arranged in a crisscross pattern between them in the conveyor, the conveyor as a whole forms a discontinuous load-bearing structure with gap distribution characteristics. At the same time, with the air injection component, the airflow can directly act on the woven belt area and penetrate the material layer, so that during the conveying process, the woven structure of the conveyor can generate multi-directional disturbance to the livestock and poultry manure, causing the material to turn over and redistribute during the conveying process, thereby avoiding the problem of uneven material layer thickness caused by random accumulation in traditional continuous belt conveyors. Compared with existing low-temperature drying equipment that uses a continuous material spreading structure, this technical solution can improve the material distribution state and airflow path from a structural perspective, effectively suppressing airflow short-circuiting and local over-drying phenomena, and avoiding the obstruction of internal moisture diffusion by the crusting of the material surface, thereby significantly improving the uniformity of the drying process and the overall drying efficiency.

[0008] Optionally, a drive pulley is fixed on the drive shaft, and a driven pulley is fixed on the driven shaft. The diameter of the drive pulley is larger than that of the driven pulley. The first belt is wound around both the drive pulley and the driven pulley. The first belt is provided with alternating load-bearing parts and deformation parts. The plastic deformation capacity of the deformation parts is greater than that of the load-bearing parts, and the length of the load-bearing parts is less than that of the deformation parts. When the first belt runs on the drive pulley and the driven pulley, the deformation parts can stretch and retract to drive the first braided belt and the second braided belt to generate relative displacement, thereby peeling off the attached manure and inhibiting its accumulation. The second belt has the same features as the first belt. Both the driving pulley and the driven pulley are provided in two sets. The first belt and the second belt are symmetrically arranged along the length of the driving shaft.

[0009] By adopting the above technical solution, a pair of driving pulleys are set on the driving shaft, and a pair of driven pulleys are set on the driven shaft. A load-bearing part and a deformation part are set on the first belt. The diameter difference between the driving and driven pulleys is used to create load-bearing and deformation parts with different deformation capabilities. This causes the first and second belts to experience periodic tension changes and elastic deformation during operation, thereby driving the first and second braided belts to generate continuous relative displacement and dynamic disturbance. This not only inhibits material adhesion and accumulation but also continuously vibrates the material layer structure, causing the livestock manure to turn over and redistribute during transportation. This prevents the formation of a dense, compacted structure and fixed airflow channels during the drying process, thus avoiding airflow short-circuiting and localized over-drying, significantly improving the uniformity of airflow distribution and the stability and efficiency of the drying process.

[0010] Optionally, the first woven tape is configured as a thin strip, and an extension portion and a partition portion are fixed on the first woven tape. The extension portion is configured in two sets, and the two sets of extension portions are respectively arranged on both sides of the width direction of the first woven tape. The extension portion is configured as a thin sheet and the extension portion is the same length as the first woven tape. The partition portion is configured in multiple sets, and the multiple sets of partition portions are arranged at equal intervals on the extension portion.

[0011] By adopting the above technical solution, a thin, extended section and multiple sets of equally spaced partitions are provided on the first woven belt. The extended section generates periodic flutter under the action of airflow, thereby applying a continuous and distributed disturbance to the livestock and poultry manure during the conveying process. Under this disturbance, on the one hand, it can cause the material to change its posture and turn over during the conveying process, avoiding the material from continuously receiving airflow on a fixed contact surface, thus preventing excessive drying of local areas due to prolonged wind exposure, and inhibiting the formation of dense crusts. On the other hand, the above disturbance improves the uniformity of material spreading on the conveyor, reduces local accumulation or uneven thickness, and allows the airflow to act more evenly on the entire material, thereby improving the uniformity of drying. In addition, the extended section can also generate periodic shaking of the manure adhering to the surface of the woven belt during the fluttering process, weakening the adhesion between the manure and the woven belt, preventing the manure from continuously sticking and accumulating on the conveyor, thereby alleviating the problem of blockage of the conveyor caused by manure accumulation and improving the continuity and stability of equipment operation.

[0012] Optionally, the bearing portion is provided with a receiving groove, and both ends of the first woven belt are fixedly provided with a first connecting portion. The first connecting portion is fixedly embedded in the receiving groove, and the first woven belt is fixed between the first belt and the second belt through the first connecting portion.

[0013] By adopting the above technical solution, since the plastic deformation capacity of the deformation part is greater than that of the bearing part, and the first connecting part is embedded in the receiving groove to achieve a stable connection between the first woven belt and the first belt and the second belt, the first belt and the second belt will form periodic tension changes and elastic deformations during operation, thereby driving the first woven belt and the second woven belt to generate continuous relative displacement and dynamic disturbance, thereby effectively peeling off the livestock and poultry manure attached to the surface of the conveyor and inhibiting the adhesion and accumulation of materials.

[0014] Optionally, the air injection assembly includes an air injection pump and a first air injection pipe. The air injection pump is located below the frame and is electrically connected to the controller. The first air injection pipe is located on the frame and on one side of the conveyor. One end of the first air injection pipe is connected to the output end of the air injection pump. Multiple sets of branch pipes are fixed on the first air injection pipe, and multiple sets of nozzles are arranged at equal intervals on the branch pipes. The nozzles are perpendicular to the first braided belt and the second braided belt. The airflow blown by the nozzles can act on the first braided belt and the second braided belt. When the airflow blows over the extension, the extension will vibrate.

[0015] By adopting the above technical solution, the airflow sprayed from the nozzle can act on the extension section, causing continuous vibration in the extension section. This creates a periodic shaking effect on the livestock and poultry manure, which on the one hand promotes continuous tumbling of the material during transportation, preventing it from being continuously subjected to airflow in a fixed posture. This prevents excessively rapid evaporation of moisture in local areas, thus avoiding the formation of a dense layer or initial crust structure and improving the uniformity of drying. On the other hand, the vibration can also continuously disturb the manure adhering to the surface of the woven belt, weakening the adhesion between the livestock and poultry manure and the woven belt, inhibiting the accumulation of manure on the conveyor, thereby reducing the risk of accumulation and blockage, ensuring the smooth flow of airflow, and improving the stability of equipment operation.

[0016] Optionally, it also includes a stacking detection assembly, which includes a mounting frame, a detection impeller, a detection shaft, a turntable, and a photoelectric sensor. The mounting frame is fixed on the frame and extends into the conveyor. A rotating seat is fixed on the mounting frame. The detection shaft is rotatably mounted on the rotating seat. The detection impeller is fixed at one end of the detection shaft, and the turntable is fixed at the other end of the detection shaft. The photoelectric sensor is fixed on the mounting frame and located on one side of the turntable. The photoelectric sensor is electrically connected to the controller. A reflective strip is fixed on the outer circumferential wall of the turntable, and the photoelectric sensor can sense the position of the reflective strip.

[0017] By adopting the above technical solution, the accumulation detection component generates different obstruction states as the degree of manure accumulation changes during material transportation. The detection impeller drives the detection shaft and turntable to rotate synchronously, and the photoelectric sensor periodically identifies the reflective strips on the turntable, thereby converting the changes in flow resistance caused by accumulation into a quantifiable rotation frequency signal. Compared with traditional direct contact or vision-based accumulation detection methods, which are easily affected by the dusty environment inside the drying chamber and thus suffer from detection distortion, this technical solution achieves stable identification of the accumulation state in a high-humidity, highly adhesive livestock and poultry manure environment through an indirect measurement path of "flow resistance - mechanical rotation response - photoelectric encoding output". This avoids the problem of detection element contamination or failure, and improves detection reliability and long-term stability.

[0018] Optionally, the frame is provided with a spacing adjustment component, which includes an adjustment drive and a sliding seat. The adjustment drive is fixed on the frame and electrically connected to the controller. A slide rail is fixed on the frame. The sliding seat is rotatably connected to one end of the driven shaft and is slidably mounted on the frame via the slide rail. The output end of the adjustment drive is connected to the sliding seat. The adjustment drive can drive the sliding seat to reciprocate on the frame, thereby adjusting the spacing between the drive shaft and the driven shaft.

[0019] By adopting the above technical solution, the spacing adjustment component can actively adjust the spacing between the drive shaft and the driven shaft. When the accumulation detection component detects that there is a relatively serious accumulation of material on the surface of the conveyor, the spacing adjustment component actively adjusts the spacing between the drive shaft and the driven shaft, increasing the spacing between them. This increases the effective span between the first belt and the second belt and causes an increase in belt deflection. Due to the increased span, the periodic stress state of the conveyor changes during operation, resulting in a more significant tension fluctuation effect between the first belt and the second belt in the heavy-load area and the rebound area. This tension fluctuation is further transmitted to the first braided belt and the second braided belt, causing a more obvious relative slippage and misalignment movement in the cross structure of the braided belt. This allows the first braided belt and the second braided belt to exert a stronger shearing disturbance on the livestock and poultry manure adhering to the surface of the conveyor. Combined with the micro-vibration effect generated by the airflow, this achieves enhanced peeling of the adhering material, thereby effectively reducing the degree of accumulation and restoring the normal conveying and air permeability of the conveyor.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting a first belt, a second belt, and multiple sets of first and second braided belts arranged in a cross-over pattern in the conveyor, the conveyor as a whole forms a discontinuous load-bearing structure with gap distribution characteristics; at the same time, with the air injection component, the airflow can directly act on the braided belt area and penetrate the material layer, so that during the conveying process, the braided structure of the conveyor can generate multi-directional disturbance to the livestock and poultry manure, causing the material to turn over and redistribute during the conveying process, thereby avoiding the problem of uneven material layer thickness caused by random accumulation in traditional continuous belt conveying, and significantly improving the uniformity of the drying process and the overall drying efficiency; 2. The stacking detection component can detect the degree of manure stacking during material transportation. Compared with traditional direct contact or vision-based stacking detection methods, which are easily affected by the dusty environment inside the drying chamber and thus cause detection distortion, this technical solution achieves stable identification of the stacking state in a high-humidity, highly adhesive livestock and poultry manure environment through an indirect measurement path. This avoids the problem of detection element contamination or failure, and improves detection reliability and long-term stability. Attached Figure Description

Detailed Implementation

[0029] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail below.

[0030] This application discloses an environmentally friendly organic fertilizer preparation device.

[0031] Reference Figure 1 and Figure 2 An environmentally friendly organic fertilizer preparation device includes a shell 1, a conveying mechanism, and an airflow control mechanism 6. A partition plate is fixed inside the shell 1, dividing the interior of the shell 1 into two independent chambers. These two chambers are respectively equipped with a drying chamber 11 and an equipment chamber 12. The conveying mechanism is installed in the drying chamber 11, and the airflow control mechanism 6 is installed in the equipment chamber 12, located to one side of the conveying mechanism. The conveying mechanism is used to spread out the filtered livestock manure for drying, while the airflow control mechanism 6 regulates the airflow throughout the entire preparation device.

[0032] Reference Figure 2 and Figure 3In this embodiment, the transmission mechanism includes a frame 2, a shearing cylinder, a feeding assembly 3, an air injection assembly 4, and a stacking detection assembly 5. A controller 13 is installed on the outer wall of the housing 1. The frame 2 is installed inside the drying chamber 11, and the shearing cylinder is installed on the frame 2. The shearing cylinder includes a feeding hopper, an active shearing roller, a driven shearing roller, and a shearing motor. The feeding hopper is fixed on the frame 2. The active and driven shearing rollers are rotatably installed inside the feeding hopper and are interlocked. The shearing motor is fixed on the feeding hopper and is electrically connected to the controller 13. The output end of the shearing motor is fixedly connected to one end of the active shearing roller via a coupling. A first transmission gear is coaxially fixed at the other end of the active shearing roller, and a second transmission gear is coaxially fixed at one end of the driven shearing roller. The first and second transmission gears mesh. The shearing cylinder is used to crush the filter cake of livestock and poultry manure after pressure filtration into uniformly sized strip-shaped particles for subsequent low-temperature drying treatment.

[0033] The feeding assembly 3 is installed on the frame 2 and is located below the shearing cylinder. The feeding assembly 3 includes a first motor 31, a drive shaft 32, a driven shaft 33, a spacing adjustment component 35, and a conveying component 34. The first motor 31 is fixed on the frame 2 and can be configured as a servo motor. The first motor 31 is electrically connected to the controller 13. The output end of the first motor 31 is fixedly connected to one end of the drive shaft 32. Several sets of bearing seats are fixed on the frame 2. The drive shaft 32 is rotatably mounted on the frame 2 through the bearing seats. The spacing adjustment component 35 is located at both ends of the driven shaft 33. The driven shaft 33 is movably mounted on the frame 2 through the spacing adjustment component 35.

[0034] A drive pulley 321 and a drive support pulley are fixedly mounted on the drive shaft 32. Two sets of drive pulleys 321 are arranged symmetrically along the length of the drive shaft 32. The drive support pulley is positioned between the two sets of drive pulleys 321. A driven pulley 331 and a driven support pulley are also fixedly mounted on the driven shaft 33. The driven shaft 33 has the same features as the drive shaft 32, except that the diameter of the drive pulley 321 is larger than the diameter of the driven pulley 331.

[0035] Reference Figure 3 and Figure 4In this embodiment, two sets of spacing adjustment components 35 are provided, and the two sets of spacing adjustment components 35 are respectively provided at both ends of the driven shaft 33. The spacing adjustment component 35 includes an adjustment drive component 351 and a sliding seat 352. The adjustment drive component 351 is fixed on the frame 2. In this embodiment, the adjustment drive component 351 can be a servo electric cylinder. The adjustment drive component 351 is electrically connected to the controller 13. A slide rail is fixed on the frame 2. The sliding seat 352 is rotatably connected to one end of the driven shaft 33. The sliding seat 352 is slidably disposed on the frame 2 through the slide rail. The output end of the adjustment drive component 351 is fixedly connected to the sliding seat 352.

[0036] Of course, in other embodiments of this application, the adjusting drive 351 can also be configured as other types of linear drive components, such as electric push rods or cylinders.

[0037] Reference Figure 4 In this embodiment, the conveyor 34 includes a first belt 341, a second belt 342, a first braided belt 343, and a second braided belt 344. The first belt 341 is provided with a support portion 3411 and a deformation portion 3412, with multiple sets of both. The support portions 3411 and deformation portions 3412 are alternately arranged on the first belt 341. The length of the support portion 3411 is less than the length of the deformation portion 3412. The support portion 3411 is made of nitrile rubber, while the deformation portion 3412 is made of neoprene rubber. One end of the support portion 3411 is fixedly connected to one end of the deformation portion 3412. The second belt 342 has the same features as the first belt 341, and the first belt 341 and the second belt 342 are symmetrically arranged along the length direction of the drive shaft 32.

[0038] The first woven strip 343 is a thin strip made of stainless steel. The first woven strip 343 has an extension portion 3431 and a partition portion 3432 on both sides along its width direction. The extension portion 3431 is a thin sheet and its length is the same as that of the first woven strip 343. The partition portion 3432 is fixed on the extension portion 3431. The length of the partition portion 3432 is greater than the width of the extension portion 3431, and one end of the partition portion 3432 is fixedly connected to the first woven strip 343. Multiple sets of partition portions 3432 are provided and are evenly spaced on the extension portion 3431, dividing the extension portion 3431 into several segments.

[0039] The second braided belt 344 has the same features as the first braided belt 343. Both ends of the first braided belt 343 are fixed with a first connecting portion 3433, and both ends of the second braided belt 344 are also fixed with a second connecting portion. A receiving groove is provided on the bearing portion 3411. The first braided belt 343 and the second braided belt 344 are disposed between the first belt 341 and the second belt 342. The first connecting portion 3433 at one end of the first braided belt 343 is connected to a set of bearing portions 3411 on the first belt 341. The first connecting portion 3433 is fixedly embedded in the receiving groove on the bearing portion 3411. The first connecting portion 3433 at the other end of the first braided belt 343 is connected to a set of bearing portions 3411 on the second belt 342. Similarly, the second connecting part at one end of the second braided belt 344 is connected to the first belt 341, the second connecting part at the other end of the second braided belt 344 is connected to the second belt 342, the first braided belt 343 overlaps the second braided belt 344, and the first braided belt 343 and the second braided belt 344 are arranged in a cross pattern.

[0040] Multiple sets of the first woven belt 343 and the second woven belt 344 are provided. The multiple sets of the first woven belt 343 and the second woven belt 344 are arranged at equal intervals along the length direction of the first belt 341. The first woven belt 343, the second woven belt 344, the first belt 341 and the second belt 342 are combined to form a mesh conveyor belt.

[0041] A tension roller is rotatably mounted on the frame 2. The first belt 341 and the second belt 342 are both wound around the driving pulley 321, the driven pulley 331, and the tension roller. The conveyor belt is rotatably mounted on the frame 2 via the driving pulley 321, the driven pulley 331, and the tension roller. More specifically, along the direction of the conveyor belt's circular rotation, the area from the driving pulley 321 to the driven pulley 331 is designated as the working area, the area from the driven pulley 331 to the tension roller is designated as the buffer zone, and the area from the tension roller to the driving pulley 321 is designated as the tensioning zone. The tensioning zone and the working area are set in parallel.

[0042] During the operation of the conveyor belt, because the diameter of the driving pulley 321 is larger than that of the driven pulley 331, the tension at the driving pulley 321 is much greater than that at the driven pulley 331. Therefore, when the conveyor belt reaches the driving pulley 321, the deformation parts 3412 corresponding to the first belt 341 and the second belt 342 will be stretched, causing the first braided belt 343 and the second braided belt 344 at the corresponding positions to move relative to each other. The direct manifestation is that the mesh gap of the transmission net increases. Similarly, when the conveyor belt reaches the driven pulley 331, the deformation part 3412 at the corresponding position will retract, thereby cleaning the manure adhering to the conveyor belt, reducing the accumulation of manure on the conveyor belt, and preventing airflow blockage.

[0043] In this embodiment, two sets of conveying components 34 are provided, and the two sets of conveying components 34 are arranged in a vertical direction, with one end of one set of conveying components 34 located directly below the feed hopper.

[0044] Reference Figure 3 , Figure 4 and Figure 5 In this embodiment, the air injection assembly 4 includes an air injection pump 41 and a first air injection pipe 42. A mounting plate is fixedly provided below the frame 2, and the air injection pump 41 is fixedly provided on the mounting plate. The air injection pump 41 is electrically connected to the controller 13. The input end of the air injection pump 41 is connected to the drying chamber 11. A first mounting seat is fixedly provided on the frame 2. The first air injection pipe 42 is located on one side of the conveyor 34. The first air injection pipe 42 is mounted above the conveyor 34 through the first mounting seat. One end of the first air injection pipe 42 is connected to the output end of the air injection pump 41. Multiple sets of branch pipes 421 are fixedly provided on the first air injection pipe 42. The branch pipes 421 extend into the conveyor 34. The branch pipes 421 are arranged parallel to the axis of the drive shaft 32. Multiple sets of nozzles 422 are fixedly arranged at equal intervals on the branch pipes 421. The jet direction of the nozzles 422 is upward in the vertical direction.

[0045] More specifically, when the nozzle 422 sprays air upwards, it passes through the first braided belt 343 and the second braided belt 344. Since the first braided belt 343 is provided with an extension 3431, when an airflow blows rapidly over the extension 3431, a pressure difference will be formed on both sides of the extension 3431. The airflow will generate separation and vortices behind the extension 3431. These vortices are not stable, but rather periodically changing aerodynamic forces. At the same time, the extension 3431 itself is set as a thin sheet. Under the action of periodically changing aerodynamic forces, the extension 3431 will vibrate. In this way, the extension section 3431 throughout the entire working area will vibrate, and the manure on it will also tumble as it moves with the conveyor belt. This can prevent the manure from becoming crusty due to local over-drying during drying, which would affect the drying quality of the manure. In addition, since the extension section 3431 throughout the entire working area will vibrate, it can also alleviate the problem of manure sticking and accumulating on the first braided belt 343 and the second braided belt 344, which could cause local blockage of the conveyor belt.

[0046] Reference Figure 6In this embodiment, the stacking detection component 5 includes a mounting frame 51, a detection impeller 52, a detection shaft 53, a turntable 54, and a photoelectric sensor 55. The mounting frame 51 is fixed on the frame 2 and is mounted above the tensioning area. Several sets of ventilation holes are evenly opened on the mounting frame 51. A rotating seat 511 is fixed on the mounting frame 51. The detection shaft 53 is rotatably mounted on the rotating seat 511. The detection impeller 52 is fixed at one end of the detection shaft 53, and the turntable 54 is fixed at the other end of the detection shaft 53. The photoelectric sensor 55 is fixed on the mounting frame 51 and is located on one side of the turntable 54. The photoelectric sensor 55 is electrically connected to the controller 13. A reflective strip 541 is fixed on the outer circumferential wall of the turntable 54, and the photoelectric sensor 55 can sense the position of the reflective strip 541.

[0047] In this embodiment, multiple sets of accumulation detection components 5 are evenly spaced on the mounting frame 51. These multiple sets of accumulation detection components 5 are used to detect possible scaling and clogging problems along the width direction of the conveyor 34.

[0048] Under normal conditions, the airflow velocity inside the entire housing 1 is within a stable range. If there is no blockage on the conveyor belt, the rotation speed of the detection impeller 52 driven by the airflow is a stable value. Once the conveyor belt is blocked, the airflow path will be obstructed, the rotation speed of the detection impeller 52 will decrease, and the corresponding photoelectric sensor 55 will detect a significant decrease in rotation speed.

[0049] Meanwhile, once the controller 13 detects that the speed of the detection impeller 52 has decreased, the controller 13 will control the spacing adjustment component 35 to start, increasing the spacing between the drive shaft 32 and the driven shaft 33. At this time, the tension of the first belt 341 and the second belt 342 increases. Combined with the setting of the drive pulley 321 and the driven pulley 331, the mutual movement between the first braided belt 343 and the second braided belt 344 is enhanced, so that the manure attached to them is quickly peeled off.

[0050] Reference Figure 7 In this embodiment, the airflow control mechanism 6 includes a blower 61, an exhaust fan 62, a condenser 63, an evaporator 64, and a filter element 65. The blower 61 is installed inside the drying chamber 11 and is fixed on the mounting plate. The blower 61 is electrically connected to the controller 13. The input end of the blower 61 is connected to the equipment compartment 12, and the output end of the blower 61 is connected to the drying chamber 11. The blower 61 can guide the treated dry airflow in the equipment compartment 12 to the drying chamber 11 and guide the dry airflow to circulate from bottom to top.

[0051] The condenser 63, evaporator 64, and filter 65 are all installed inside the equipment compartment 12. The evaporator 64 is fixed to the mounting plate, and a support frame is fixed to the mounting plate. The condenser 63 is fixed to the support frame and is supported above the evaporator 64 by the support frame. There are two sets of evaporators 64 and condensers 63, which are symmetrically arranged along the length of the mounting plate. Both the evaporator 64 and the condenser 63 are electrically connected to the controller 13. The condenser 63 is used to dehumidify the airflow, and the evaporator 64 is used to heat the dehumidified airflow so that the airflow temperature rises to 75°C.

[0052] A filter element 65 is mounted above the condenser 63 and is configured as a filter mesh. The filter element 65 filters the airflow entering the equipment compartment 12 and traps dust in the airflow. An exhaust fan 62 is fixedly mounted on the partition plate and is electrically connected to the controller 13. Multiple sets of exhaust fans 62 are installed on the partition plate and are located above the conveyor 34. The exhaust fan 62 is used to guide the airflow in the drying chamber 11 into the equipment compartment 12.

[0053] The implementation principle of the environmentally friendly organic fertilizer preparation equipment in this application embodiment is as follows: After high-pressure filtration, the livestock and poultry manure first enters the shearing cylinder, where it is crushed into strip-shaped particles of relatively uniform size under the meshing action of the active shearing roller and the driven shearing roller, thereby increasing the specific surface area of ​​the material and weakening the agglomeration structure, providing favorable conditions for subsequent moisture diffusion and evaporation; the crushed material falls onto the mesh conveyor belt composed of the first belt 341, the second belt 342, and the first woven belt 343 and the second woven belt 344 arranged in a cross-weave pattern, realizing continuous spreading and conveying; During the operation of the conveyor belt, the periodic change in belt tension caused by the difference in diameter between the driving pulley 321 and the driven pulley 331 causes the deformation part 3412 on the belt to stretch and retract, thereby driving the braided belt to produce relative displacement and mesh opening and closing changes, thus periodically peeling and loosening the highly viscous manure adhering to the conveyor belt, effectively inhibiting material accumulation and blockage of the conveying mechanism. Under the action of the air injection component 4, the airflow penetrates the mesh conveyor belt from bottom to top. When the airflow passes through the thin sheet-like extension 3431 on the woven belt, it induces unsteady vortices, which excite the extension 3431 to flutter, causing the material to continuously undergo micro-disturbance and tumbling during the conveying process. This disrupts the local airflow short-circuit path, promotes uniform airflow distribution, and enhances the convective heat transfer and moisture diffusion processes inside and outside the material layer.

[0054] Meanwhile, the accumulation detection component 5, located above the tension zone, uses airflow to drive the detection impeller 52 to rotate, and the photoelectric sensor 55 monitors its rotation speed in real time to reflect the unobstructed airflow channel. When it is detected that the airflow is obstructed and the impeller speed decreases due to material accumulation, the controller 13 drives the spacing adjustment component 35 to adjust the spacing between the drive shaft 32 and the driven shaft 33, increasing the tension of the conveyor belt and the relative movement amplitude of the braided belt, thereby enhancing the material peeling ability and achieving adaptive clearing of blockages.

[0055] In addition, the airflow control mechanism 6 dehumidifies the circulating airflow through the condenser 63, and then heats it through the evaporator 64 to form a low-humidity, high-temperature airflow. Under the action of the blower 61 and the exhaust fan 62, a bottom-up circulating airflow field is constructed to achieve stable control of temperature and humidity and directional flow of airflow in the drying chamber 11. The filter element 65 traps dust in the circulating airflow to ensure the stability of system operation.

[0056] The above are all optional embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
