Description

Technical Field

[0001] The present invention relates to the technical field of waste treatment, and in particular to a device and method for treating artificial pavement waste. Background Art

[0002] Man-made pavement waste refers to the waste materials generated during the construction, maintenance, renovation, or demolition of man-made pavements (such as asphalt pavements and cement concrete pavements). Currently, cement concrete pavement waste includes cement stone, aggregate, and steel bars.

[0003] Existing artificial pavement waste processing devices are designed to recycle cement concrete pavement waste, crushing old concrete into aggregates of varying particle sizes for use in the production of recycled concrete, roadbed filler, or cement-stabilized gravel. While the waste is crushed by a crushing mechanism, the cement concrete pavement waste contains rebar, a recyclable metal that requires manual separation from the concrete blocks. However, existing artificial pavement waste processing devices are unable to separate the rebar from the concrete blocks, requiring additional labor, time, and safety precautions.

[0004] In order to solve the above problems, we propose an artificial pavement waste treatment device and treatment method. Summary of the Invention

[0005] The purpose of the present invention is to solve the problem that the artificial pavement waste processing device in the prior art cannot separate the steel bars and concrete blocks from the crushed waste, and to propose an artificial pavement waste processing device and processing method.

[0007] A frame is provided in the outer shell, and the frame is located below the two crushing rollers. Diversion slopes are provided on both sides of the frame, and a plurality of evenly distributed sieve holes are provided on the diversion slopes. Guide frames are fixedly installed on both sides of the frame, and the guide frames pass through the outer shell. Electromagnets are provided on both sides of the frame, and the electromagnets are arranged in a columnar shape and parallel to the sieve holes. A moving mechanism is installed on the frame, and the moving mechanism is connected to the electromagnet and is used to drive the electromagnet to move above the diversion slope.

[0008] Preferably, the driving mechanism includes two first servo motors, each of which is fixedly mounted on the outer shell, and the output shaft of the first servo motor is fixedly connected to the crushing roller and is used to drive the crushing roller to rotate.

[0009] Preferably, a guide channel is fixedly installed in the outer shell, and the guide channel is located above the gap between the two crushing rollers.

[0010] Preferably, protective covers are fixedly installed on both sides of the outer shell, and the protective covers are located on the sides of the crushing roller. A dust collection device is installed on the outer shell.

[0011] Preferably, the moving mechanism includes four slides fixedly mounted on the frame, two of the slides are arranged in a group on the side of the frame and are symmetrically distributed, a slider is slidably arranged in each of the slides, one end of the slider is rotatably mounted on the end of the electromagnet, a lead screw is rotatably mounted in each of the slides, the lead screw passes through the slider and is threadedly connected to the slider, power components are installed on both sides of the frame, and the power components are used to drive the two sliders on the same side to move along the slide.

[0012] Preferably, the power assembly includes two connecting shafts, which are rotatably mounted outside the slideway, and the connecting shafts pass through the slideway and are fixedly connected to the lead screw. A first bevel gear is fixedly mounted on the end of the connecting shaft, and a second servo motor is fixedly mounted on the side of the frame. A second bevel gear is fixedly mounted on the output shaft end of the second servo motor, and the second bevel gear is meshed with the first bevel gears on both sides.

[0013] Preferably, a driven wheel is sleeved and fixedly mounted on one end of the electromagnet, a strip frame is fixedly mounted on the frame, and a plurality of equidistantly distributed friction parts are provided on the strip frame. The friction parts are in contact with the driven wheel and transmission is carried out between the two through friction force.

[0014] Preferably, two symmetrically distributed elastic members are fixedly connected to both sides of the frame, and the elastic members are fixedly connected to the outer shell.

[0015] Preferably, racks are fixedly mounted on both sides of the frame, the racks extend out of the outer shell, a third servo motor is fixedly mounted on the outer shell, an incomplete gear is fixedly mounted on the output shaft end of the third servo motor, and the incomplete gear is meshed with the rack.

[0016] A method for treating artificial pavement waste comprises the following steps: The cement concrete pavement waste is directed through the diversion channel to between the two relatively rotating crushing rollers; The crushing rollers are driven by a driving mechanism to rotate synchronously in opposite directions to crush the waste; The crushed materials fall onto the guide slope with the sieve holes, and are preliminarily screened through the sieve holes; During the screening process, the electromagnet is driven by the moving mechanism to move back and forth above the guide slope to absorb the steel bars in the crushed material; By intermittently rotating the electromagnet, different positions of the electromagnet are directed toward the guide slope; After the screening is completed, the electromagnet is controlled to be powered off so that the adsorbed steel bars fall off and are collected.

[0017] Compared with the prior art, the present invention has the following beneficial effects: The device crushes the waste using two crushing rollers, which then screen the crushed material with the sieve holes on the frame. This screens out any incompletely crushed waste while retaining the steel bars on the diversion slope. A third servo motor drives the frame back and forth, shaking the crushed material on the diversion slope and improving the screening efficiency of the sieve holes.

[0018] The moving mechanism drives the electromagnet to reciprocate above the diversion slope, thereby driving the electromagnet to reciprocate above the diversion slope. The electromagnet absorbs the rebar remaining on the diversion slope. While crushing, the device also automatically separates the rebar from the crushed concrete as recyclable metal, eliminating the need for manual separation of rebar from concrete crushed materials, saving both manpower and time.

[0019] When the electromagnet moves, the driven wheel on the electromagnet intermittently contacts the friction part, and the electromagnet intermittently rotates back and forth while moving on the guide slope. Different positions on the electromagnet are rotated to a state facing the guide slope, so that different positions on the electromagnet can adsorb steel bars, avoiding the adsorption of steel bars at a fixed position on the electromagnet, and increasing the number of steel bars adsorbed by the electromagnet.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] Example 1 Reference Figure 1-7 A device for processing artificial pavement waste includes an outer shell 1, within which two spaced-apart crushing rollers 2 are rotatably mounted. A drive mechanism is mounted outside the outer shell 1 for driving the two crushing rollers 2 to rotate. A frame 3 is mounted within the outer shell 1, positioned below the two crushing rollers 2. A diversion slope 4 is provided on each side of the frame 3, each of which has a plurality of evenly distributed sieve holes 5. Guide frames 6 are fixedly mounted on each side of the frame 3, each extending through the outer shell 1. Electromagnets 7 are mounted on each side of the frame 3, each columnar and parallel to the sieve holes 5. A moving mechanism is mounted on the frame 3, connected to the electromagnets 7 and configured to drive the electromagnets 7 to move above the diversion slopes 4.

[0024] The drive mechanism includes two first servo motors 8, each fixedly mounted on the outer shell 1. The output shafts of the first servo motors 8 are fixedly connected to the crushing rollers 2 and are used to drive the crushing rollers 2 in rotation. A diversion channel 9 is fixedly mounted within the outer shell 1, located above the gap between the two crushing rollers 2. Protective covers 10 are fixedly mounted on both sides of the outer shell 1, covering the sides of the crushing rollers 2. A dust collection device 25 is installed on the outer shell 1 to absorb dust generated during operation of the waste handling device. The protective covers 10 separate the personnel from the crushing rollers 2, providing protection for the personnel.

[0025] By placing cement concrete pavement waste into the diversion channel 9, the waste is diverted to the space between the two crushing rollers 2 through the diversion channel 9, and the crushing rollers 2 are driven to rotate by the first servo motor respectively, so that the crushing rollers 2 on both sides rotate synchronously and in opposite directions, thereby crushing the waste between the two crushing rollers 2. The crushed debris falls onto the frame 3, and the debris on the frame 3 is diverted to both sides through the diversion slopes 4 on both sides. The debris is screened in conjunction with the sieve holes 5 on the frame 3, and the waste that is not completely crushed can be screened out. At the same time, the steel bars in the waste remain on the diversion slope 4.

[0026] The moving mechanism includes four slides 11 fixedly mounted on the frame 3. Two slides 11 are arranged in a group on the side of the frame 3 and are symmetrically distributed. A slider 12 is slidably mounted in each slide 11. One end of the slider 12 is rotatably mounted on the end of the electromagnet 7. A lead screw 13 is rotatably mounted in each slide 11. The lead screw 13 passes through the slider 12 and is threadedly connected to the slider 12. A power assembly is installed on both sides of the frame 3. The power assembly is used to drive the two sliders 12 on the same side to move along the slide 11. The power assembly includes two connecting shafts 14, which are rotatably mounted on the outside of the slide 11. The connecting shaft 14 passes through the slide 11 and is fixedly connected to the lead screw 13. A first bevel gear 15 is fixedly mounted on the end of the connecting shaft 14. A second servo motor 16 is fixedly mounted on the side of the frame 3. A second bevel gear 17 is fixedly mounted on the output shaft end of the second servo motor 16. The second bevel gear 17 meshes with the first bevel gears 15 on both sides.

[0027] During the screening process, the electromagnet 7 is driven to reciprocate above the diversion slope 4 by the moving mechanism. Specifically, the second servo motor 16 drives the second bevel gear 17 to rotate, and the second bevel gear 17 drives the first bevel gear 15 to rotate. The first bevel gear 15, the connecting shaft 14, and the lead screw 13 rotate synchronously, which can drive the slider 12 to move along the direction of the slideway 11. The sliders 12 on both sides move in a synchronized direction and at the same speed, thereby driving the electromagnet 7 to reciprocate above the diversion slope 4. The electromagnet 7 absorbs the steel bars remaining on the diversion slope 4.

[0028] Example 2 proposed based on Example 1: Reference Figure 2-7 A driven pulley 18 is mounted and fixedly mounted on one end of the electromagnet 7. A strip frame 19 is fixedly mounted on the frame 3. The strip frame 19 is provided with a plurality of equally spaced friction portions 20. The friction portions 20 contact the driven pulley 18, and transmission is achieved through friction between the friction portions 20 and the driven pulley 18. An elastic strip 26 is fixedly connected between the slider 12 and the driven pulley 18.

[0029] When the electromagnet 7 moves back and forth above the guide slope 4, the driven wheel 18 on the electromagnet 7 is in intermittent contact with the friction part 20, and the friction part 20 and the driven wheel 18 are transmitted through friction force, so that multiple friction parts 20 intermittently drive the driven wheel 18 to rotate, and the driven wheel 18 and the electromagnet 7 rotate synchronously, and the elastic strip 26 is deformed. When the driven wheel 18 is separated from the friction part 20, the elastic force of the elastic strip 26 drives the driven wheel 18 and the electromagnet 7 to reset, so that the electromagnet 7 intermittently reciprocates while moving on the guide slope 4, and different positions on the electromagnet 7 are rotated to a state facing the guide slope 4, so that different positions on the electromagnet 7 can adsorb steel bars, avoiding a fixed position on the electromagnet 7 adsorbing steel bars, and the number of steel bars adsorbed by the electromagnet 7 can be increased.

[0030] Two symmetrically distributed elastic members 21 are fixedly connected to both sides of the frame 3, and both elastic members 21 are fixedly connected to the outer shell 1. Racks 22 are fixedly mounted on both sides of the frame 3, extending outside the outer shell 1. A third servo motor 23 is fixedly mounted on the outer shell 1, and a partial gear 24 is fixedly mounted on the output shaft end of the third servo motor 23, which meshes with the rack 22.

[0031] When the crushed material falls onto the diversion slope 4, the device performs screening. After the screening is completed, the steel bar adsorption process is performed, and the above process is repeated. During the screening process, a third servo motor 23 is used to drive the incomplete gear 24 to rotate. The incomplete gear 24 intermittently drives the rack 22 to move, which can drive the frame 3 to move horizontally along the direction of the guide frame 6. The elastic member 21 is deformed at the same time. When the incomplete gear 24 separates from the rack 22, the elastic member 21 drives the frame 3 to reset, thereby driving the frame 3 to reciprocate. By shaking the crushed material on the diversion slope 4, the screening efficiency of the sieve hole 5 is improved.

[0032] The overall working principle is as follows: cement concrete pavement waste is placed into the diversion channel 9, and diverted to between the two crushing rollers 2 through the diversion channel 9. The crushing rollers 2 are driven to rotate by the first servo motor respectively, so that the crushing rollers 2 on both sides rotate synchronously and in opposite directions, thereby crushing the waste between the two crushing rollers 2. The crushed debris falls onto the frame 3, and the debris on the frame 3 is diverted to both sides through the diversion slopes 4 on both sides. The debris is screened in conjunction with the sieve holes 5 on the frame 3, and the waste that is not completely crushed can be screened out. At the same time, the steel bars in the waste remain on the diversion slope 4.

[0033] When the crushed material falls onto the diversion slope 4, the device performs screening. After the screening is completed, the steel bar adsorption process is performed, and the above process is repeated. During the screening process, a third servo motor 23 is used to drive the incomplete gear 24 to rotate. The incomplete gear 24 intermittently drives the rack 22 to move, which can drive the frame 3 to move horizontally along the direction of the guide frame 6. The elastic member 21 is deformed at the same time. When the incomplete gear 24 separates from the rack 22, the elastic member 21 drives the frame 3 to reset, thereby driving the frame 3 to reciprocate. By shaking the crushed material on the diversion slope 4, the screening efficiency of the sieve hole 5 is improved.

[0034] During the screening process, the electromagnet 7 is driven to reciprocate above the diversion slope 4 by the moving mechanism. Specifically, the second servo motor 16 drives the second bevel gear 17 to rotate, and the second bevel gear 17 drives the first bevel gear 15 to rotate. The first bevel gear 15, the connecting shaft 14, and the lead screw 13 rotate synchronously, which can drive the slider 12 to move along the direction of the slideway 11. The sliders 12 on both sides move in a synchronized direction and at the same speed, thereby driving the electromagnet 7 to reciprocate above the diversion slope 4. The electromagnet 7 absorbs the steel bars remaining on the diversion slope 4.

[0035] When the electromagnet 7 moves back and forth above the guide slope 4, the driven wheel 18 on the electromagnet 7 is in intermittent contact with the friction part 20, and the friction part 20 and the driven wheel 18 are transmitted through friction force, so that multiple friction parts 20 intermittently drive the driven wheel 18 to rotate, and the driven wheel 18 and the electromagnet 7 rotate synchronously, and the elastic strip 26 is deformed. When the driven wheel 18 is separated from the friction part 20, the elastic force of the elastic strip 26 drives the driven wheel 18 and the electromagnet 7 to reset, so that the electromagnet 7 intermittently reciprocates while moving on the guide slope 4, and different positions on the electromagnet 7 are rotated to a state facing the guide slope 4, so that different positions on the electromagnet 7 can adsorb steel bars, avoiding a fixed position on the electromagnet 7 adsorbing steel bars, and the number of steel bars adsorbed by the electromagnet 7 can be increased.

[0036] After adsorbing the steel bars, the electromagnet 7 returns to its initial position, and the electromagnet 7 is powered off again. The steel bars on the electromagnet 7 fall down due to gravity, and the staff can take them out in a centralized manner.

[0037] A method for treating artificial pavement waste comprises the following steps: The cement concrete pavement waste is diverted through the diversion channel 9 to between the two relatively rotating crushing rollers 2; The crushing roller 2 is driven by the driving mechanism to rotate synchronously in the opposite direction to crush the waste; The crushed materials fall onto the guide slope 4 with sieve holes 5, and the crushed materials are preliminarily screened through the sieve holes 5; During the screening process, the electromagnet 7 is driven by the moving mechanism to move back and forth above the guide slope 4 to absorb the steel bars in the crushed material; By intermittently rotating the electromagnet 7, its different positions are all directed toward the guide slope 4; After the screening is completed, the electromagnet 7 is powered off to allow the adsorbed steel bars to fall off and be collected.

[0038] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
