Description

Technical Field

[0001] This invention relates to the field of construction waste sorting technology, specifically to a sorting device for construction waste treatment that prevents material from getting stuck. Background Technology

[0002] Sorting equipment for construction waste treatment is the core equipment for realizing the resource recycling of construction waste. Its core function is to accurately classify mixed construction waste according to physical characteristics such as composition, particle size, density, and magnetism, separating recyclable components from impurities that need to be harmlessly disposed of, thus providing a preliminary guarantee for subsequent resource-based processing and environmentally friendly disposal.

[0003] Construction waste, such as demolition waste, renovation waste, and road construction waste, has a complex composition and is usually mixed with concrete blocks, brick and tile fragments, waste steel bars, waste wood, plastics, slag, glass, and other materials. Direct landfilling will cause resource waste and environmental pollution.

[0004] Traditional drum screens and vibrating screens are prone to getting tangled in flexible debris. Flexible debris (such as plastic sheeting and fiber bags) can easily get tangled and hooked during movement, forming "flocculent balls" that cause screen holes to become clogged. Further improvements and optimizations are needed. Summary of the Invention

[0005] The purpose of this invention is to provide a sorting device for construction waste treatment that prevents material from getting stuck, effectively preventing blockage caused by flexible debris.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A sorting device for construction waste treatment with anti-snagging material handling includes a sorting main support frame and multiple sorting flow channels with upward openings and inclined arrangement fixed on the sorting main support frame. The multiple sorting flow channels are arranged in a stepped shape. Each sorting flow channel has an upward opening material receiving channel below it. The material receiving channel below each sorting flow channel is connected to the input end of the adjacent sorting flow channel inclined downward. The bottom of the sorting flow channel is equipped with multiple vertically connected sorting and screening holes; The input end of the uppermost sorting flow channel is connected to an initial input hopper; The bottom of the lowest sorting and flow channel is equipped with an upward-facing tail material collection box; The output end of the sorting flow channel is provided with a discharge temporary storage tank, and a discharge inclined pipe is connected to the side of the discharge temporary storage tank. A discharge storage box is connected to the lower end of the discharge inclined pipe. Each sorting flow channel is equipped with a feeding mechanism. The feeding mechanism includes a feeding support plate set above the sorting flow channel. The feeding support plate has multiple feeding connection holes that run vertically through the channel. A feeding deflection support plate is rotatably connected to the feeding connection holes. The feeding deflection support plate has an eccentric connection hole that runs vertically through the channel. A sorting feeding rod is fixed in the eccentric connection hole. The input end of the sorting flow channel is equipped with a debris storage box with an upward-facing opening.

[0007] Preferably, multiple sorting vibration modules are fixed on the outer side of the sorting flow channel.

[0008] Note: Under vibration, construction waste will gradually slide along the sorting flow channel from the input end to the output end.

[0009] Preferably, the feeding support plate is connected to the upper side of the sorting flow channel through a reciprocating feeding drive mechanism. The reciprocating feeding drive mechanism includes a feeding drive support plate fixed to the side of the sorting flow channel. A feeding support slide rail arranged in parallel to each other is fixed on the top of the feeding drive support plate. A feeding drive slider is slidably connected on the feeding support slide rail. A material feeding drive slider is fixed with an upward-facing material feeding lifting fixed cylinder. A material feeding lifting sliding cylinder is slidably connected in the material feeding lifting fixed cylinder. The top of the material feeding lifting sliding cylinder is fixedly connected to the material feeding support plate through a lifting fixed connecting rod. The material lifting fixed cylinder is equipped with a material lifting drive rod for driving the material lifting sliding cylinder to move up and down.

[0010] Explanation: During the process of construction waste sliding in the sorting and flow channel, the material feeding mechanism separates the clumps of construction waste and screens out fibrous flexible waste such as strips of cloth and plastic sheeting.

[0011] Preferably, a deflection drive support ring is fixed on the top of the material feeding deflection support plate and is coaxial with it. A deflection driven gear ring is fixed on the outside of the deflection drive support ring. A deflection drive motor is fixed on the upper side of the material feeding support plate. A deflection drive gear is fixed on the output shaft of the deflection drive motor. The deflection drive gear is meshed with the deflection driven gear ring.

[0012] Note: The deflection movements of multiple material feeding deflection support plates are synchronized, and the material feeding deflection support plates perform periodic clockwise and counterclockwise deflection movements around the axis of the material feeding connection hole, which is conducive to more complete contact between multiple sorting material feeding rods and construction waste.

[0013] Preferably, the sorting and feeding rod is provided with a barb hooking mechanism. The sorting and feeding rod has a hollow structure inside. The barb hooking mechanism includes a barb linkage rod that is slidably disposed inside the sorting and feeding rod. The side wall of the sorting and feeding rod has multiple barb connecting oblique holes that are interconnected inside and outside. Hooked barbs are slidably connected in the barb connecting oblique holes. One end of the hooked barb inside the sorting and feeding rod is fixedly connected to the barb linkage rod. The upper end of the sorting and feeding rod is fixed with a barb extension drive housing. The upper end of the barb linkage pull rod extends into the barb extension drive housing. The barb extension drive housing is provided with a barb extension drive rod for driving the barb linkage pull rod to move.

[0014] Explanation: When the outer end of the hook barb extends from the oblique hole of the barb connection, multiple hook barbs form a barb structure on the sorting barb, which can more effectively pick out and separate debris from construction waste.

[0015] Preferably, there is a discharge driving mechanism on the upper side of the discharge temporary storage tank. The discharge driving mechanism includes a discharge driving support plate fixed on the upper side of the discharge temporary storage tank. A horizontally extending discharge driving support slide rail is fixed on the side of the discharge driving support plate. A discharge driving support slider is slidably connected on the discharge driving support slide rail. A downward-facing discharge lifting fixed cylinder is fixed on the discharge drive support slider. A discharge lifting sliding cylinder is slidably connected inside the discharge lifting fixed cylinder. The lower end of the discharge lifting sliding cylinder is connected to the discharge drive plate through the discharge toggle link. The discharge lifting fixed cylinder is equipped with a discharge lifting drive rod for driving the discharge lifting sliding cylinder to move up and down.

[0016] Note: Under the drive of the discharge drive mechanism, the construction waste in the discharge temporary storage tank smoothly enters the discharge storage box along the discharge inclined pipe.

[0017] Preferably, the upper side of the waste storage box is provided with a waste removal mechanism. The waste removal mechanism includes a removal support plate fixed to the upper side of the waste storage box. A removal support slide rail extending vertically is fixed to the side of the removal support plate. A removal support slider is slidably connected to the removal support slide rail. The removal support slider is connected to the waste removal plate through a removal drive linkage. Multiple vertically penetrating waste removal constraint slots are provided on the waste removal plate.

[0018] Instructions: The debris stripping mechanism is used to transfer fibrous flexible waste from multiple sorting and feeding rods to a temporary debris storage box.

[0019] Preferably, the side of the waste storage box is provided with a negative pressure exhaust mechanism, and the side of the waste storage box is provided with a negative pressure exhaust connection hole. The negative pressure exhaust mechanism includes a waste negative pressure exhaust pipe that is slidably connected in the negative pressure exhaust connection hole. The negative pressure exhaust pipe for miscellaneous items is located outside the miscellaneous items storage box. One end of the pipe is connected to the negative pressure storage box via a negative pressure transfer exhaust pipe. The negative pressure storage box is connected to a negative pressure suction machine via a negative pressure connecting pipe; A telescopic drive support plate is fixed to the outside of the temporary storage box for miscellaneous items. A telescopic support slide rail is fixed to the telescopic drive support plate. The extension direction of the telescopic support slide rail is parallel to the sliding direction of the negative pressure exhaust pipe for miscellaneous items. A telescopic support slider is slidably connected to the telescopic support slide rail. The telescopic support slider is fixedly connected to the negative pressure exhaust pipe for miscellaneous items.

[0020] Instructions: The negative pressure exhaust mechanism is used to transfer fibrous flexible waste from the waste storage bin to the negative pressure storage bin.

[0021] Compared with the prior art, the beneficial effects of the present invention are reflected in the following aspects: 1. The present invention has a reasonable structural design and adopts a multi-stage fine screening design. The material passes through multiple flow channels with screen holes. The fine material screened out at each stage falls directly into the lower layer, while the coarse material continues to move forward, realizing multiple classifications of particle size and improving the separation purity of different components. 2. The present invention has outstanding anti-clogging and anti-entanglement capabilities. Each sorting tank is equipped with an independent material feeding mechanism, which can actively stir and move the material, effectively preventing large pieces or fibrous materials from accumulating and bridging on the screen surface. 3. The material feeding rod of the present invention has lifting and rotating functions, which can adapt to material layers of different thicknesses and break up clumps from multiple angles; 4. The sorting and feeding rod of the present invention has a built-in retractable "hook barb". When it encounters plastic sheeting, woven bags and other debris that are easy to get tangled, the barb can be extended to actively hook and wrap the debris onto the feeding rod and then lift it up to peel it off. This fundamentally solves the problem of flexible debris getting tangled on the screen or equipment parts. The action is controllable and does not affect the normal flow of materials.

[0022] 5. The discharge drive mechanism of the present invention can actively push materials into the discharge inclined pipe at the discharge port to prevent the discharge port from being blocked; 6. The debris stripping mechanism of the present invention can transfer fibrous flexible waste attached to multiple sorting and feeding rods to the debris temporary storage box at the feeding end by means of a stripping plate that moves up and down.

[0034] In practical applications, this invention is used to perform preliminary step-by-step screening of construction waste according to its size. In practical applications of this invention, the higher end of the sorting flow channel 20 is the input end, and the lower end is the output end. The flow direction of the sorting flow channel 20 is inclined at a 5° angle to the horizontal plane, and the inclination direction of multiple sorting flow channels 20 is consistent. Each sorting flow channel 20 is numbered from top to bottom as F1, F2, F3, ..., Fn; The sorting and screening holes 201 on each sorting flow channel 20 are numbered from top to bottom as S1, S2, S3, ..., Sn; The discharge temporary storage tanks 23 connected to each sorting flow channel 20 are numbered from top to bottom as P1, P2, P3, ..., Pn; The miscellaneous temporary storage boxes 24 connected to each sorting flow channel 20 are numbered from top to bottom as Z1, Z2, Z3, ..., Zn; From top to bottom, the aperture of the sorting sieve holes 201 on each sorting flow channel 20 gradually decreases, and the ratio of the aperture of the sorting sieve holes 201 on two adjacent sorting flow channels 20 is 1:0.8. The diameter of the sorting sieve hole 201 on the uppermost sorting flow channel 20 is 200mm; Each material receiving groove 21 is numbered from top to bottom as L1, L2, L3, ..., Ln; The construction waste to be processed is conveyed to the initial input hopper 22 by a conveyor belt conveyor of existing technology. The construction waste in the initial input hopper 22 is discharged from its lower end and enters the sorting flow channel 20 numbered F1. The sorting vibration module 202 continuously applies vibration of 5~20Hz to the sorting flow channel 20. Under the action of vibration, the construction waste will gradually slide along the direction from the input end to the output end in the sorting flow channel 20. During the process of construction waste sliding in the sorting and flow channel 20, construction waste with a diameter smaller than the sorting screen hole 201 numbered S1 passes through it from top to bottom and falls into the material receiving channel 21 numbered L1. Construction waste with a diameter larger than the sorting screen hole 201 numbered S1 continues to slide down along the sorting and flow channel 20 numbered F1 and is discharged from its output end into the discharge temporary storage channel 23 numbered P1. Construction waste falling into the receiving trough 21 of L1 will gradually slide down along the receiving trough 21 and enter the sorting flow trough 20 of F2. The construction waste continues to slide in the sorting flow trough 20 of F2. Construction waste with a diameter smaller than the sorting screen hole 201 of S2 will pass through from top to bottom and fall into the receiving trough 21 of L2. Construction waste with a diameter larger than the sorting screen hole 201 of S2 will continue to slide down along the sorting flow trough 20 of F2 and be discharged from its output end into the discharge temporary storage trough 23 of P2. Similarly, the construction waste in the discharge temporary storage tank 23 numbered P2 will continue to be transferred downwards, and the construction waste will be screened by the sorting and flow tanks 20 numbered F3, ..., Fn in sequence. Finally, the construction waste smaller than the sorting screen hole 201 numbered Sn will pass through from top to bottom and fall into the tail material collection box 221. During the process of construction waste sliding in the sorting and flow channel 20, the material feeding mechanism 30 separates the clumps of construction waste and screens out fibrous flexible waste such as strips of cloth and plastic sheeting. The material feeding drive slider 343 is driven by a servo motor of the prior art through a screw drive to move along the material feeding support slide rail 342. The extension direction of the material feeding support slide rail 342 is parallel to the flow direction of the sorting flow channel 20. The material feeding drive slider 343 can then drive the material feeding lifting fixed cylinder 344, the material feeding lifting sliding cylinder 345, the lifting fixed connecting rod 346, the material feeding support plate 31, and multiple sorting material feeding rods 33 to move together. The movement process from the output end to the input end of the sorting flow channel 20 is called the "material feeding forward stroke", and the movement process from the input end to the output end of the sorting flow channel 20 is called the "material feeding reset stroke". During the "forward stroke of material feeding", the inner rod of the material feeding lifting drive rod 347 is in the retracted state, so that the material feeding support plate 31 and multiple sorting material feeding rods 33 are in a low position, so that multiple sorting material feeding rods 33 are inserted into the construction waste. When multiple sorting material feeding rods 33 are inserted into the construction waste and move from the output end to the input end of the sorting flow channel 20, they can separate the fibrous flexible waste in the construction waste and make these fibrous flexible wastes wrap around the multiple sorting material feeding rods 33. In the barb hook mechanism 40, each barb connecting oblique hole 401 is arranged obliquely upward. When the inner rod of the barb extension drive rod 431 retracts, it drives the barb linkage pull rod 41 to move from bottom to top. The barb linkage pull rod 41 then drives the outer end of the hook barb 42 to extend out of the barb connecting oblique hole 401. At this time, the barb hook mechanism 40 is said to be in the open state. When the inner rod of the barb extension drive rod 431 extends, it drives the barb linkage pull rod 41 to move from top to bottom. The barb linkage pull rod 41 then drives the hook barb 42 to retract back into the barb connecting oblique hole 401. At this time, the barb hook mechanism 40 is said to be in the closed state. When the material feeding support plate 31, together with multiple sorting feeding rods 33, moves to the input end of the sorting flow channel 20, the barb hook mechanism 40 is in the open state. Then, the inner rod of the material feeding lifting drive rod 347 extends and drives the material feeding lifting sliding cylinder 345, the lifting fixing link 346, the material feeding support plate 31, and multiple sorting feeding rods 33 to move upward together, so that multiple sorting feeding rods 33 are pulled out from the construction waste. Due to the hooking action of the hook barbs 42, the fibrous flexible waste can be firmly constrained on the multiple sorting feeding rods 33 and pulled out together, thereby separating the fibrous flexible waste from the construction waste. Subsequently, the material feeding drive slider 343 continues to move towards the direction of the debris storage box 24, driving multiple sorting material feeding rods 33 to be above the debris storage box 24. At this time, the multiple sorting material feeding rods 33 are in each debris stripping constraint slot 630. The debris stripping mechanism 60 transfers the fibrous flexible waste on the multiple sorting material feeding rods 33 to the debris storage box 24. When the multiple sorting and feeding rods 33 are positioned in the corresponding debris stripping constraint slots 630, the barb hook hanging mechanism 40 is closed. Then, the stripping support slider 622 is driven by a conventional servo motor fixed on the stripping support plate 61 via a screw drive to move along the stripping support slide rail 621. The stripping support slider 622 drives the debris stripping plate 63 to move from top to bottom, stripping the fibrous flexible waste on the multiple sorting and feeding rods 33 into the debris temporary storage box 24. The fibrous flexible waste in the waste storage box 24 is transferred and stored in the negative pressure storage box 73 by the negative pressure exhaust mechanism 70. The negative pressure suction machine 74 evacuates the inside of the negative pressure storage box 73 through the negative pressure connecting pipe 741, so that the inside of the negative pressure storage box 73 is in a negative pressure state. Under the action of negative pressure, the fibrous flexible waste in the waste storage box 24 will be sucked into the inside of the negative pressure storage box 73 through the waste negative pressure exhaust pipe 71 and the negative pressure transfer exhaust pipe 72. Furthermore, the telescopic support slider 752 is driven by a prior art servo motor fixed on the telescopic drive support plate 75 through a lead screw drive to move along the telescopic support slide rail 751. The telescopic support slider 752 then drives the debris negative pressure discharge pipe 71 to move along the axial direction of the negative pressure discharge connection hole 701, so that the debris negative pressure discharge pipe 71 extends into the debris temporary storage box 24, which is conducive to more thoroughly transferring and storing fibrous flexible waste in the debris temporary storage box 24 into the negative pressure temporary storage box 73. Under the drive of the discharge drive mechanism 50, the construction waste in the discharge temporary storage tank 23 smoothly enters the discharge storage box 232 along the discharge inclined pipe 231. The discharge drive support slider 53 is driven by the existing technology servo motor fixed on the discharge drive support plate 51 through the screw drive to move along the discharge drive support slide rail 52. The discharge drive support slider 53 then drives the discharge lifting fixed cylinder 541, the discharge lifting sliding cylinder 542, the discharge toggle connecting rod 543 and the discharge drive plate 55 to move together, so that the discharge drive plate 55 moves closer to or away from the discharge inclined pipe 231. The process of the discharge drive plate 55 gradually moving closer to the discharge inclined pipe 231 is called the "discharge forward stroke", and the process of the discharge drive plate 55 gradually moving away from the discharge inclined pipe 231 is called the "discharge reset stroke". During the "forward discharge stroke", the inner rod of the discharge lifting drive rod 544 is in the extended state, causing the discharge drive plate 55 to be inserted into the construction waste and gradually push the construction waste towards the discharge inclined pipe 231. During the "reset discharge stroke", the inner rod of the discharge lifting drive rod 544 is in the retracted state, causing the lower end of the discharge drive plate 55 to be higher than the construction waste in the discharge temporary storage tank 23, causing the discharge drive plate 55 to return to the end away from the discharge inclined pipe 231, and then the "forward discharge stroke" is performed again, causing the inner rod of the discharge lifting drive rod 544 to be in the extended state, causing the discharge drive plate 55 to be inserted into the construction waste again. This cycle is repeated to help the construction waste smoothly enter the discharge storage box 232 along the discharge inclined pipe 231.

[0035] During the "forward stroke of material feeding", the output shaft of the deflection drive motor 323 drives the material feeding deflection support disk 32 to rotate periodically around the axis of the material feeding connection hole 310 through the meshing connection of the deflection drive gear 324 and the deflection driven gear ring 322. The deflection motion of multiple material feeding deflection support disks 32 is carried out synchronously. The material feeding deflection support disk 32 rotates periodically clockwise 30° and counterclockwise 30° around the axis of the material feeding connection hole 310, which is conducive to more complete contact between multiple sorting material feeding rods 33 and construction waste.
