Description

Technical Field

[0001] This invention belongs to the field of food waste treatment technology, specifically relating to a high-efficiency clean conversion and treatment device for agricultural and food waste. Background Technology

[0002] Food waste is extremely complex in composition. In addition to regular food scraps, hard lumps, and small bone fragments, a large amount of flexible, strip-shaped debris such as melon vines, vines, plant branches, and long fibers are mixed in during the pre-processing of catering and fruits and vegetables. These debris are tough, vary in length, and are extremely prone to tangling and agglomerating. After the material undergoes solid-liquid and oil-water separation, these flexible, strip-shaped debris will enter the downstream processing stage along with the organic material. However, the blade structure of current traditional crushing equipment is fixed and the operation mode is single. When vines and seedlings become entangled on the blade, they accumulate and adhere to the blade surface, continuously increasing the load on the blade shaft and causing a continuous decline in crushing efficiency. In severe cases, it can cause the blade to jam, requiring frequent manual cleaning of the entangled material, further reducing processing efficiency. Summary of the Invention

[0003] To address the problems existing in the prior art, the present invention provides a highly efficient cleaning and conversion treatment device for agricultural and kitchen waste, which avoids the continuous accumulation and entanglement of materials and prevents the blade from jamming.

[0004] The specific technical solution adopted in this invention is as follows:

[0005] A high-efficiency clean conversion and treatment device for agricultural and kitchen waste includes a sorting unit, a feeding unit, a dewatering unit, and a back-end processing unit arranged sequentially. The device is characterized by a crushing unit located between the feeding unit and the dewatering unit. The crushing unit includes a frame and a crushing assembly. The frame has a feeding bin; the crushing assembly is rotatably disposed within the feeding bin. The crushing assembly consists of two sets of rotary cutting blades arranged in parallel and rotating towards each other. Each rotary cutting blade set includes a cutter shaft, moving blade assemblies, spacers, and rotating blades. Multiple moving blade assemblies are arranged sequentially along the axial direction of the cutter shaft, and spacers are provided between adjacent sets of moving blade assemblies. The spacers have cavities inside for accommodating the rotating blades, and slots communicating with the cavities are provided on the spacers. The rotating blades are slidably disposed within the slots and have the freedom to extend and retract radially along the spacers.

[0006] In one embodiment, the spacer includes an inner ring body, an outer ring body, and a reset member. The inner ring body and the outer ring body are coaxially sleeved on the outer periphery of the cutter shaft, forming a circumferential relative rotation pair between the inner ring body and the outer ring body. The moving blade assembly is provided with an annular groove, and the end of the outer ring body is rotatably embedded in the annular groove. A gap is provided between the inner ring body and the outer ring body. The outer ring body has a radial through groove. The through groove has a trumpet-shaped structure, and the rotary blade is disposed in the gap, with the blade tail connected to the outer peripheral wall of the inner ring body. The blade head is slidably disposed in the through groove. In the initial no-load state, the rotary blade is completely hidden and stored inside the through groove. When the cutter shaft rotates without load, the reset member limits the synchronous rotation of the inner ring body and the outer ring body, restricting their relative rotation and preventing the rotary blade from accidentally extending. Only under the pressure of material load, the inner ring body and the outer ring body generate a relative angle, driving the rotary blade to extend and achieve the cutting operation.

[0007] Annular components are fixedly provided on both sides of the outer ring body. The annular components on both sides are fixedly connected to the adjacent moving blade assembly by pins. The outer periphery of the annular component is provided with a plurality of spaced driven teeth. An auxiliary roller is also provided on the frame. The auxiliary roller is oscillating on the frame by a connecting rod. The auxiliary roller is provided with a driving tooth that is adapted to mesh with the driven teeth. A handwheel is provided at the end of the auxiliary roller. The handwheel drives the auxiliary roller to rotate.

[0008] In one embodiment, the side face of the annular member near the outer ring body is a wedge-shaped structure.

[0009] In one embodiment, a plurality of return levers are provided within the gap, the return levers including upper levers and lower levers; a plurality of lower levers are provided on the outer peripheral wall of the inner ring, and a plurality of upper levers are provided on the inner peripheral wall of the outer ring, the upper levers and the lower levers abutting against each other or separating from each other as the inner and outer rings rotate.

[0010] In one embodiment, the reset element is a spring.

[0011] In one embodiment, a spiral conveyor roller is provided below the feed hopper.

[0012] In one embodiment, the dewatering unit is integrated and installed on the frame, and the discharge port of the spiral conveyor roller is connected to the feed end of the dewatering unit to realize continuous feeding and dewatering of crushed materials.

[0013] The beneficial effects of this invention are:

[0014] This invention employs radially telescopic rotary blades in conjunction with an inner and outer ring spacer structure capable of relative rotation. Two sets of rotary cutting blades rotate synchronously in opposite directions, and each set of moving blade components rotates with the blade shaft to form a symmetrical biting shearing and pulverizing zone. The spacers achieve precise positioning, ensuring a constant working distance between the moving blade components. After the material falls into the working gap between the two sets of blades, it is grabbed by the moving blades rotating in opposite directions and shredded and refined under the combined action of shearing, tearing, and squeezing, completing the continuous pulverizing operation. During the pulverizing process, when vine-like or seedling-like materials fall into the spacer's area, they tend to entangle and accumulate on the spacer's surface. When material entanglement occurs on the spacer's surface, the inner and outer rings generate circumferential relative motion. The inner ring drives the rotary blades to extend radially outward along the spacer. The extended rotary blades can quickly cut and peel off the flexible strip-like debris entangled on the outside of the spacer, preventing the material from continuously accumulating and entangled, and preventing the blades from jamming.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0023] Specific implementation examples Figures 1 to 5As shown, this invention relates to a high-efficiency clean conversion and treatment equipment for agricultural and kitchen waste, comprising a sorting unit, a feeding unit, a dewatering unit 7, and a back-end processing unit arranged sequentially. A crushing unit is located between the feeding unit and the dewatering unit 7, and the crushing unit includes a frame 1 and a crushing assembly 2. The frame 1 has a feeding bin 11; the crushing assembly 2 is rotatably disposed within the feeding bin 11. The crushing assembly 2 consists of two sets of rotary cutting blades 21 arranged in parallel and rotating towards each other. Each rotary cutting blade set 21 includes a cutter shaft 22, moving blade assemblies 23, spacers 24, and rotating blades 25. Multiple moving blade assemblies 23 are arranged sequentially along the axial direction of the cutter shaft 22, and spacers 24 are provided between adjacent sets of moving blade assemblies 23. The spacers 24 have cavities inside for accommodating the rotating blades 25, and slots 244 communicating with the cavities are provided on the spacers 24. The rotating blades 25 are slidably disposed within the slots 244 and have the freedom to extend and retract radially along the spacers 24.

[0024] The sorting unit includes a sealed sorting machine housing, a variable frequency material conveying mechanism, an intelligent debris identification and detection mechanism, a high-speed automatic rejection mechanism, and a negative pressure dust collection and deodorization mechanism. The variable frequency material conveying mechanism is used to convey raw kitchen waste materials at a uniform speed, ensuring that the materials are evenly spread and conveyed stably. The intelligent debris identification and detection mechanism can identify non-degradable foreign objects such as hard debris, metal, glass, and stones mixed in the materials in real time. The high-speed automatic rejection mechanism performs precise point-to-point rejection of the identified debris, realizing automated sorting and deodorization. The negative pressure dust collection and deodorization mechanism seals the sorting station to collect air, preventing dust overflow and odor diffusion, ensuring the purity of materials entering the downstream processes, and effectively protecting the safe and stable operation of the downstream crushing, dehydration, and fermentation equipment.

[0025] The feeding bin 11 is connected to the discharge port of the sorting unit. The materials sorted by the sorting unit enter the feeding bin 11 in sequence and are then sheared and crushed by the rotary cutter group 21.

[0026] Two sets of rotary cutting blades 21 continuously rotate synchronously in opposite directions. The evenly arranged moving blade components 23 rotate in opposite directions with the blade shaft 22, forming symmetrically engaged shearing and crushing zones. After being sorted by the sorting unit, the material falls into the working gap 243 between the two sets of blades and is quickly engaged and gripped by the high-speed rotating moving blade components 23. As the blade shaft 22 continues to rotate, the moving blade components 23 on both sides cooperate to apply a stable combination of shearing, tearing, and compressing forces to the material, gradually tearing, chopping, and refining large pieces of material, completing the continuous crushing operation. Relying on the precise spacing and positioning of the spacer 24, the working distance between each set of moving blade components 23 remains constant, effectively ensuring the uniformity and stability of the crushing operation.

[0027] Under normal operating conditions, the rotary blade 25 retracts into the internal cavity of the partition sleeve 24, and the blade tip of the rotary blade 25 will not extend beyond the outer peripheral wall of the partition sleeve 24. Once material entanglement occurs on the outer wall of the partition sleeve 24, the rotary blade 25 extends outward through the through groove 244 to cut off the vines and other materials entangled on the surface of the partition sleeve 24, and peel off the flexible strip-shaped debris attached to the outside of the partition sleeve 24, thereby preventing the continuous accumulation and entanglement of materials and avoiding blade jamming.

[0028] Combination Figure 4 The spacer 24 includes an inner ring 241, an outer ring 242, and a reset member. The inner ring 241 and the outer ring 242 are coaxially sleeved on the outer periphery of the cutter shaft 22, forming a circumferential relative rotating pair between the inner ring 241 and the outer ring 242. The moving cutter assembly 23 is provided with an annular groove, and the outer ring 242 is rotatably embedded in the annular groove. A gap 243 is provided between the inner ring 241 and the outer ring 242. The outer ring 242 is provided with a radial through groove 244. The through groove 244 has a trumpet-shaped structure. The rotary blade 25 is provided in the gap 243, and the blade tail is connected to the outer peripheral wall of the inner ring 241. The blade head is slidably provided in the through groove 244, and the two ends of the reset member are respectively connected to the inner ring 241 and the outer ring 242.

[0029] In the initial no-load state, the rotary blade 25 is completely hidden and stored inside the through groove 244; when the cutter shaft 22 rotates under no-load, the reset member limits the inner ring 241 and the outer ring 242 to rotate synchronously, restricting the relative rotation between the two and preventing the rotary blade 25 from accidentally extending. Only under the pressure of the material load, the inner ring 241 and the outer ring 242 generate a relative angle, driving the rotary blade 25 to extend and realize the cutting operation.

[0030] The feeding unit includes two symmetrically arranged pressure rollers 12, which rotate in opposite directions and rotate at a lower speed than the rotary cutting blade assembly 21. (The arrow indicates the rotation direction of the blade shaft 22.)

[0031] When one end of the material is wrapped around the outer wall of the spacer 24 and the other end is clamped between the pressure rollers 12, the material is pulled and twisted by the pressure rollers 12, causing the inner ring 241 and the outer ring 242 to rotate circumferentially relative to each other. This causes the rotary blade 25 mounted on the inner ring 241 to slide radially relative to the outer ring 242, so that the cutting head of the rotary blade 25 extends outward quickly along the radial through groove 244 of the outer ring 242, thereby cutting and severing the flexible strip-shaped debris wrapped around the outer ring 242 and the outside of the cutter shaft 22, and quickly releasing the material from the entanglement state.

[0032] After the entangled debris is removed, the outer ring 242 rotates back to its original position under the action of the reset component. The rotating blade 25 retracts back into the gap 243, and the outer ring 242 restores its smooth outer wall structure, without affecting the normal crushing operation of the equipment. This process is fully automated, requiring no machine shutdown or manual cleaning, thus solving the problems of easy entanglement, jamming, and frequent shutdowns in traditional crushing equipment.

[0033] The reset component is spring 5.

[0034] In another embodiment, combined Figure 5 Annular components 245 are fixed to both sides of the outer ring body 242. Each annular component 245 is connected to an adjacent moving cutter assembly 23 via pins 247. Multiple spaced driven teeth 246 are arranged around the outer periphery of the annular component 245. An auxiliary roller 3 is also provided on the frame 1. The two ends of the auxiliary roller 3 are oscillating on the frame 1 via connecting rods 31, and the auxiliary roller 3 has driving teeth that match the driven teeth 246. (The arrow indicates the rotation direction of the cutter shaft 22.)

[0035] Since the annular component 245 is integrated with the outer ring body 242, when vines become entangled on the outside of the outer ring body 242, auxiliary cleaning operations can be performed by stopping the machine. First, remove the pin 247 connecting the annular component 245 and the moving blade assembly 23 to release the fixed limiting constraint between the annular component 245 and the moving blade assembly 23, allowing the outer ring body 242 to rotate freely circumferentially relative to the moving blade assembly 23. Then, swing the connecting rod 31 to rotate the auxiliary roller 3 closer to the position of the rotary cutting blade assembly 21, so that the driving teeth on the outer circumference of the auxiliary roller 3 precisely mesh with the driven teeth 246 on the annular component 245. The roller shaft end of the auxiliary roller 3 is equipped with a handwheel, which can be manually driven to rotate the auxiliary roller 3. Through gear meshing, the outer ring body 242 rotates circumferentially relative to the inner ring body 241 (the rotation direction of the outer ring body 242 is opposite to the rotation direction of the blade shaft 22), driving the rotary blade to extend out of the through groove 244, thereby cutting off the entangled material on the outside.

[0036] After the entangled material is completely cut off and cleaned, the swing linkage 31 moves away from the auxiliary roller 3, disengages the gear meshing, and rotates the outer ring 242 circumferentially back to its original position. This causes the rotating blade 25 to retract into the gap 243 between the inner ring 241 and the outer ring 242, restoring the complete and smooth outer circumferential structure of the spacer 24. Subsequently, the pin 247 can be reinstalled to fix the ring part 245, and the equipment can resume normal crushing operation.

[0037] The side of the annular component 245 near the outer ring body 242 has a wedge-shaped structure. This wedge-shaped structure can guide and direct entangled vines and other debris, allowing the entangled debris accumulated on the top of the annular component 245 to slide smoothly to the outer periphery of the outer ring body 242, ensuring that the entangled debris is within the cutting range of the rotary blade 25, thus guaranteeing the cutting and cleaning effect.

[0038] In other embodiments, combined with Figure 6 Multiple return levers 4 are provided within the gap 243, each including an upper lever 41 and a lower lever 42. Multiple lower levers 42 are provided on the outer peripheral wall of the inner ring 241, and multiple upper levers 41 are provided on the inner peripheral wall of the outer ring 242. The lower levers 42 and upper levers 41 form the return lever 4 structure. The lower levers 42 can rotate with the inner ring 241, forming a contact-limiting or mutually distancing engagement with the upper levers 41. A rotary blade 25 is integrally arranged inside the gap 243. The tail of the rotary blade 25 is fixed to the outer wall of the inner ring 241, and the head of the rotary blade 25 can slide through the radial through groove 244 of the outer ring 242. Under normal operating conditions, the inner ring 241 and the outer ring 242 are relatively stationary, the lower blade 42 and the upper blade 41 are stably fitted and in contact, the rotary blade 25 is completely hidden inside the gap 243, the blade tip does not protrude from the outer circle of the outer ring 242, ensuring that the outer wall of the spacer 24 is smooth and without protrusions, and does not affect the normal crushing operation of the equipment.

[0039] When the entangled material accumulates to a certain extent, the entanglement resistance drives the inner ring 241 and the outer ring 242 to rotate relative to each other in a circumferential direction. The inner ring 241 causes the lower lever 42 to shift relative to the upper lever 41 and disengage from the contact limit. This, in turn, causes the rotary blade 25 fixed to the inner ring 241 to slide radially relative to the outer ring 242, causing the rotary blade 25 to extend rapidly outward along the radial through groove 244. The extended rotary blade 25 rotates synchronously with the cutter shaft 22, performing annular shearing to cut the flexible strip-shaped debris entangled on the outer ring 242 and the outside of the cutter shaft 22, quickly peeling off and removing the accumulated entangled material, and eliminating the risk of equipment jamming.

[0040] After the entangled debris is removed, the inner ring 241 and the outer ring 242 rotate relative to each other and reset. The lower lever 42 re-engages with the upper lever 41 and is limited. The rotating blade 25 retracts synchronously into the gap 243. The outer ring 242 restores its smooth outer wall structure, and the equipment returns to stable normal crushing operation.

[0041] Below the feed hopper 11 is a spiral conveyor roller 6. Two sets of spiral conveyor rollers 6 are mounted on the frame 1, rotating symmetrically in opposite directions. Their spiral guide vanes employ a variable-pitch spiral structure to facilitate the smooth entry of the pulverized kitchen waste into the dewatering unit 7 for dewatering. The discharge port of the spiral conveyor roller 6 is connected to the dewatering unit 7, which separates the moisture from the solid material in the kitchen waste. After dewatering, the low-moisture solid material is stably output to the downstream processing unit, thus achieving efficient solid-liquid separation of kitchen waste.

[0042] The dewatering unit 7 includes a solid-liquid separation unit and an oil-water separation unit, which are integrated and work in sequence. The solid-liquid separation unit employs a high-speed centrifugal separation structure to perform deep solid-liquid separation on the crushed and compressed mixed wastewater, effectively trapping suspended fine organic residues and solid debris, achieving complete solid-liquid separation. The separated fine solid residues are returned to the downstream fermentation process, while the oily wastewater is sent to the oil-water separation unit. The oil-water separation unit uses a constant-temperature heating sedimentation oil-water separation structure. Temperature control reduces the viscosity of the oil, and gravity stratification is used to achieve efficient separation of floating oil, emulsified oil, and water in the wastewater, completing the resource recovery of oil and the initial purification of wastewater.

[0043] After oil-water separation, the solid organic material enters the back-end processing unit for further treatment. The back-end processing unit includes a dry anaerobic fermentation unit and a waste gas treatment unit. The dry anaerobic fermentation unit employs a closed-loop dry anaerobic fermentation tank structure, equipped with an intelligent temperature control system, a mixing mechanism, an anaerobic bacteria inoculation mechanism, and a pressure-stabilizing aeration component. It performs dry anaerobic fermentation on the solid organic material obtained from the front-end separation, achieving the degradation, stabilization, and resource conversion of organic matter from kitchen waste to prepare organic fertilizer raw materials or soil amendment substrates. The waste gas treatment unit is connected to the dry anaerobic fermentation unit and all front-end closed processing stations. The waste gas treatment unit can be a multi-stage combined waste gas purification device, specifically including a gas collection and guiding component, a spray scrubbing tower, a photocatalytic oxidation purification component, an activated carbon adsorption device, a dehumidification and demisting component, and a variable frequency exhaust mechanism, with each structure arranged in series. The waste gas treatment unit is connected to the dry anaerobic fermentation unit and each front-end sealed treatment station. It can collect the odorous waste gas and organic waste gas generated during the crushing, dehydration, fermentation and sorting processes of the whole set of equipment. The waste gas is then subjected to acid and alkali spray washing to remove harmful acid and alkali media, photocatalytic degradation of organic odors, and deep adsorption and purification by activated carbon. Finally, it is discharged after dehumidification and demisting to meet the standards. It effectively removes odorous pollutants such as hydrogen sulfide, ammonia and volatile organic compounds, completely eliminates the problem of waste gas overflow and odor diffusion, and realizes the harmless, environmentally friendly and sealed operation of the whole set of equipment.

[0044] The equipment is equipped with an intelligent control unit, which is electrically connected to the sorting unit, feeding unit, crushing unit, dewatering unit 7 and back-end processing unit. It can realize the linkage start and stop of each process, adaptive load adjustment, automatic fault alarm and real-time monitoring of operating data, and realize the fully automatic intelligent unattended operation of the equipment.
