Description

Technical Field

[0001] The present application relates to the field of waste recycling technology, and in particular to a construction waste treatment device and a construction waste regeneration system. Background Art

[0002] In recent years, my country has produced more than 3 billion tons of construction waste each year, accounting for about 40% of the total urban waste. Construction waste is an important resource for renewable building materials. Recycling construction waste can create huge economic value.

[0003] Sorting and separation of construction waste is a crucial link in the resource utilization of construction waste. Construction waste is transported to a closed stockpile plant for pre-treatment, loading, feeding, and crushing. The physical properties of steel are used to magnetically separate and collect steel bars. Masonry separation equipment is used to separate masonry. The density differences and gravity of various types of waste are used to separate light materials such as wood, plastic, paper, and film from masonry. The collected dust is transported to concrete production equipment as powder for concrete production.

[0004] When loading construction waste, transportation equipment such as forklifts or excavators are used to unload the construction waste onto a conveying device or the feed port of a crusher. In order to reduce collisions between equipment during the loading process, under normal circumstances, a certain height difference needs to be maintained between the transportation equipment and the equipment below that receives the raw materials when unloading. Due to the height difference when unloading, construction waste is more likely to collide with the equipment below when falling. Long-term use can easily damage the equipment that receives the construction waste raw materials. Summary of the invention

[0005] In order to reduce the impact of construction waste on equipment that receives the construction waste during the construction waste loading process, the present application provides a construction waste processing equipment and a construction waste recycling system.

[0006] The present application provides a construction waste treatment device and a construction waste recycling system that adopts the following technical solutions:

[0007] A construction waste processing equipment, including a crusher, a loading conveyor device and a discharging conveyor device, the loading conveyor device is used to feed the construction waste into the crusher, the discharging conveyor device is used to transport the construction waste crushed by the crusher to the next process, the construction waste processing equipment also includes a material guiding device, the material guiding device includes a bracket and a material guiding plate, the material guiding plate is rotatably connected to the bracket through a rotating connecting piece, the rotating connecting piece deviates from the center of the material guiding plate, the material guiding plate is provided with a counterweight, the counterweight is located on the side of the rotating connecting piece away from the center of the material guiding plate, the bracket is provided with a limiting piece, the counterweight is used to drive the lower surface of the material guiding plate to abut the limiting piece; the bracket and the lower surface of the material guiding plate A buffer mechanism is connected between the guide plate and the support, and the buffer mechanism is located on the side of the guide plate away from the counterweight. The buffer mechanism includes a buffer cylinder and a piston. One end of the buffer cylinder is connected to the bracket, and the buffer cylinder is closed at one end close to the bracket. The piston is clearance-matched with the buffer cylinder. A magnet is provided at the end of the piston away from the buffer cylinder, and the magnet is connected to the lower surface of the guide plate by magnetic attraction. When the guide plate abuts against the limit member, the side of the guide plate away from the counterweight is located at the upper limit position, and when the piston abuts against the closed end of the buffer cylinder, the side of the guide plate away from the counterweight is located at the lower limit position, and a gap margin is left between the working surface of the loading and conveying device.

[0008] By adopting the above technical solution, when the material guide plate is not used for guiding materials, one side of the material guide plate on which the counterweight is arranged maintains a state of abutting against the surface of the limiting piece under the action of the gravity of the counterweight; when the transport equipment is loading materials, the transport equipment unloads the construction waste onto the material guide plate of the material guide device, and the material guide plate is impacted by the construction waste, and the side of the material guide plate away from the counterweight rotates and tilts downward, and at the same time, the cavity between the piston of the buffer mechanism and the inner wall of the buffer cylinder is rapidly compressed, and the air in the cavity between the piston and the inner wall of the buffer cylinder forms a buffering effect on the impact received by the material guide plate.

[0009] The speed of construction waste is reduced due to the buffering effect of the buffer mechanism. As the air in the cavity between the piston and the inner wall of the buffer cylinder is gradually discharged, the piston abuts the closed end of the buffer cylinder. At the same time, the guide plate away from the counterweight rotates downward and approaches the working surface of the discharge conveying device, causing the construction waste to slide along the guide plate onto each feeding roller. Since the speed of the construction waste is reduced and the drop of the construction waste onto the feeding roller is reduced, the impact of the construction waste on the feeding roller is reduced.

[0010] When the construction waste on the guide plate is transferred to the discharging conveying device, the guide plate rotates and resets under the action of the counterweight. At the same time, the guide plate drives the piston rod to reset through the magnetic attraction. During the rotation and reset of the guide plate, the volume of the cavity formed between the piston and the inner wall of the buffer cylinder gradually increases, and air is sucked in from the gap between the piston cylinder and the inner wall of the buffer cylinder, so that the buffer mechanism has a buffering effect on the reset process of the guide plate, making the reset action of the guide plate slower, which is beneficial to reduce the dust formed by the powder remaining on the surface of the guide plate.

[0011] Optionally, the material guide plate is a rectangular plate, the length direction of the material guide plate is arranged along the center line direction of the rotating connecting member, and the length direction of the material guide plate is arranged along the feeding direction of the loading and conveying device.

[0012] By adopting the above technical solution, the guide plate is set as a rectangular plate, and its length direction is along the feeding direction of the loading conveyor device. When the transport equipment is unloading, the transport equipment can be unloaded on the long side of the guide plate, so that the transport equipment has a larger operating space during the unloading process. On the other hand, the loading conveyor device is a device for conveying materials. Usually, the length direction of the loading conveyor device is consistent with the feeding direction. Therefore, by making the length direction of the guide plate consistent with the length direction of the loading conveyor device, it is beneficial to reduce the area occupied by the guide device and the loading conveyor device and improve space utilization.

[0013] Optionally, a sealing plate is provided at one end of the buffer cylinder away from the bracket, and the sealing plate is provided with a through hole for avoiding the piston rod of the piston.

[0014] By adopting the above technical solution, the sealing plate can shield the space inside the piston cylinder and reduce the dust from entering the piston cylinder; and the piston rod of the piston can be further supported, making the relative movement between the piston and the buffer cylinder more stable.

[0015] Optionally, a buffer sliver is arranged around the piston, and a peripheral side surface of the piston is provided with an annular groove for avoiding the buffer sliver, and the buffer sliver abuts against the inner wall of the buffer cylinder.

[0016] By adopting the above technical solution, the buffer cotton strip can increase the resistance of air circulation in the buffer cylinder, thereby improving the buffering effect of the buffer structure.

[0017] Optionally, the feeding and conveying device includes a feeding rack, which is provided with a plurality of equidistantly arranged feeding rollers, and the feeding rack is provided with a feeding drive mechanism for driving the feeding rollers to rotate synchronously, and a screening gap is formed between every two adjacent feeding rollers; the construction waste processing equipment also includes an auxiliary discharging device, which is used to receive the construction waste raw materials falling from the screening gap.

[0018] By adopting the above technical solution, construction waste falls from the guide plate to the various feeding rollers of the feeding conveyor device, and the powder and fine particles in the construction waste can fall from the screening gap to the auxiliary discharging device, which is beneficial to reduce the dust generated by the powder in the construction waste during the crushing process of the crusher.

[0019] Optionally, the discharging conveying device includes a discharging conveyor belt and a discharging frame. The discharging conveying device is arranged to be gradually inclined upward in a direction away from the crusher. An inclined guide plate is provided at the lower part of the crusher. The inclined guide plate is used to guide the crushed construction waste to the discharging conveyor belt. The lower edge of the inclined guide plate abuts against the working surface of the discharging conveyor belt, and a screening gap is formed between the lower edge of the inclined guide plate and the working surface of the discharging conveyor belt.

[0020] By adopting the above technical scheme, a small amount of powder or fine particles are formed after the construction waste is crushed. The screening gap between the lower edge of the inclined guide plate and the working surface of the discharge conveyor belt can screen out the powder and fine particles in advance, thereby reducing the powder and fine particles from forming floating dust in subsequent processes.

[0021] Optionally, a chamfered surface is provided on the lower edge of the inclined guide plate, and an angle formed between the chamfered surface and the working surface of the discharge conveyor belt is oriented in a feeding direction along the discharge conveying device.

[0022] By adopting the above technical solution, the angle between the chamfered surface and the surface of the discharge conveyor belt can buffer more powder and fine particles, reducing the situation where powder and fine particles cannot be screened out in time and are directly taken away by the discharge conveyor belt; and by setting the chamfered surface, the thickness of the lower edge of the guide plate can be reduced, making it easier for powder and fine particles to pass through the screening gap.

[0023] Optionally, a transfer trough is provided at one end of the discharging conveying device close to the crusher, and the transfer trough is used to receive the construction waste materials screened out from the screening gaps, and the transfer trough is tilted downward and extends to the top of the auxiliary discharging device.

[0024] By adopting the above technical solution, the transfer chute transfers the construction waste raw materials screened out by the screening gaps to the auxiliary discharging device, and then transports them through the auxiliary discharging device.

[0025] Optionally, the discharging frame is fixedly provided with a material shifting piece, the material shifting piece is located at one end of the discharging frame close to the crusher, and the material shifting piece is used to shift the construction waste located on the discharging conveyor belt.

[0026] By adopting the above technical solution, the material shifting piece can shift the construction waste on the discharge conveyor belt. When the crushed construction waste falls on the discharge conveyor belt, as the discharge conveyor belt transports the construction waste, the material shifting piece will shift the construction waste, causing the powder and fine particles between the gaps of the construction waste to fall onto the discharge conveyor belt, thereby allowing the powder and fine particles to be screened out from the screening gaps as much as possible.

[0027] A construction waste recycling system comprises any one of the construction waste treatment equipments described above, and the construction waste treatment equipment is used in conjunction with building material production equipment.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. When the construction waste is discharged onto the guide plate of the guide device, the guide plate is impacted by the construction waste, and the side of the guide plate away from the counterweight rotates and tilts downward. The air in the cavity between the piston and the inner wall of the buffer cylinder has a buffering effect on the impact of the guide plate, and the drop of the construction waste onto the loading roller is reduced, which is conducive to reducing the impact of the construction waste on the loading roller;

[0030] 2. The guide plate is set as a rectangular plate, and its length direction is along the feeding direction of the loading conveyor. When the transport equipment is unloading, the transport equipment can be unloaded on the long side of the guide plate, so that the transport equipment has a larger operating space during the unloading process;

[0031] 3.

DETAILED DESCRIPTION

[0039] The following is combined with Figure 1-5 This application is described in further detail.

[0040] The present application embodiment discloses a construction waste treatment device. Figure 1 The construction waste processing equipment includes a crusher 2, a loading conveyor device 1, a discharging conveyor device 3 and a material guiding device 4. The material guiding device 4 is used to guide the construction waste unloaded by the transportation equipment into the working surface of the loading conveyor device 1. The loading conveyor device 1 is used to feed the construction waste into the crusher 2. The discharging conveyor device 3 is used to transport the construction waste crushed by the crusher 2 to the next process.

[0041] Reference Figure 2 The feeding and conveying device 1 includes a feeding frame 11, and the feeding frame 11 is provided with a plurality of feeding rollers 12 arranged at equal intervals. The feeding frame 11 is provided with a feeding driving mechanism 14 for driving each feeding roller 12 to rotate synchronously. The feeding driving mechanism 14 includes a first motor 141. The first motor 141 drives the feeding rollers 12 to rotate synchronously through a belt transmission assembly 142, so as to drive the construction waste to move closer to the crusher 2, and a screening gap 13 is formed between every two adjacent feeding rollers 12.

[0042] The construction waste is discharged from the guide plate 42 onto the various feeding rollers 12 of the feeding conveyor 1, and the powder and fine particles in the construction waste are first screened out to reduce the dust generated during the crushing process of the crusher 2. The construction waste treatment equipment also includes an auxiliary discharge device 5 for receiving the construction waste materials that fall from the screening gap 13. The auxiliary conveying device is a belt conveying device, and the auxiliary discharge device 5 is used to receive the construction waste materials that fall from the screening gap 13.

[0043] Reference Figure 1 and Figure 3The material guide device 4 includes a bracket 41 and a material guide plate 42. The material guide plate 42 is rotatably connected to the bracket 41 through a rotating connector 43. The rotating connector 43 includes a rotating shaft 431 fixed to the bracket 41 and two rotating seats 432 fixed to the lower surface of the material guide plate 42. The two rotating seats 432 are rotatably connected to the rotating shaft 431 respectively. The rotating connector 43 deviates from the center of the material guide plate 42. The material guide plate 42 is provided with a counterweight 44. The counterweight 44 is located on the side of the rotating connector 43 away from the center of the material guide plate 42. The counterweight 44 is a metal block such as copper or iron. The counterweight 44 is arranged in a plurality of pieces arranged along the center line direction of the rotating connector 43. The bracket 41 is provided with a stopper 45. The stopper 45 is abutted against the lower surface of the side of the material guide plate 42 where the counterweight 44 is arranged. The counterweight 44 drives the material guide plate 42 to rotate to a position abutting against the stopper 45 by gravity.

[0044] Reference Figure 1 and Figure 4 At least two buffer mechanisms 46 are connected between the bracket 41 and the lower surface of the guide plate 42. Each buffer mechanism 46 is arranged along the length direction of the guide plate 42. The buffer mechanism 46 is located on the side of the guide plate 42 away from the counterweight 44. The buffer mechanism 46 includes a buffer cylinder 461 and a piston 462. One end of the buffer cylinder 461 is fixedly connected to the bracket 41. The end of the buffer cylinder 461 close to the bracket 41 is closed. The piston 462 is clearance-matched with the buffer cylinder 461. The end of the piston 462 away from the buffer cylinder 461 is provided with a magnet 463. The magnet 463 is hinged to the piston rod of the piston 462. The guide plate 42 is a steel plate. The magnet 463 is connected to the lower surface of the guide plate 42 by magnetic attraction.

[0045] When the guide plate 42 abuts against the limit piece 45, the guide plate 42 is parallel to the working surface of the discharge conveying device 3, and the side of the guide plate 42 away from the counterweight 44 is located at the upper limit position. At the same time, a cavity is formed between the piston 462 of the buffer mechanism 46 and the inner wall of the buffer cylinder 461. When the piston 462 abuts against the inner wall of the closed end of the buffer cylinder 461, the side of the guide plate 42 away from the counterweight 44 is located at the lower limit position, and a gap margin is left between the working surface of the loading conveying device 1, so that the impact of the construction waste from the guide plate 42 is not easily transmitted to the loading roller 12.

[0046] The buffering principle of the material guiding device 4 for construction waste is as follows: the construction waste is unloaded from the transportation equipment to the material guiding plate 42, and the material guiding plate 42 forms an impact effect, causing the material guiding plate 42 to tilt downward on the side away from the counterweight 44. At the same time, the cavity between the piston 462 of the buffer mechanism 46 and the inner wall of the buffer cylinder 461 is rapidly compressed, and the air in the cavity between the piston 462 and the inner wall of the buffer cylinder 461 has a buffering effect on the impact effect on the material guiding plate 42.

[0047] The speed of construction waste is reduced due to the buffering effect of the buffer mechanism 46. As the air in the cavity between the piston 462 and the inner wall of the buffer cylinder 461 is gradually discharged, the piston 462 abuts against the closed end of the buffer cylinder 461. At the same time, the guide plate 42 rotates downward away from the side of the counterweight 44 and approaches the working surface of the discharge conveying device 3, causing the construction waste to slide along the guide plate 42 onto each loading roller 12. Since the speed of the construction waste is reduced and the drop of the construction waste onto the loading roller 12 is reduced, it is helpful to reduce the impact of the construction waste on the loading roller 12.

[0048] After the construction waste on the guide plate 42 is transferred to the discharging conveying device 3, the guide plate 42 is reset under the action of the counterweight 44, and the guide plate 42 drives the piston rod to reset, so that the buffer mechanism 46 waits to play a buffering role again.

[0049] Reference Figure 1 The guide plate 42 is a rectangular structure, and the length direction of the guide plate 42 is arranged along the center line direction of the rotating connector 43, and the length direction of the guide plate 42 is arranged along the feeding direction of the loading and conveying device 1, so that the guide device 4 and the loading and conveying device 1 are arranged more compactly. A buffer pad 422 is provided on the upper surface of the guide plate 42, and the buffer pad 422 can be made of a relatively light material such as a wood board or a rubber board. A plurality of reinforcing ribs 423 are welded and fixed on the lower surface of the guide plate 42, and the length direction of the reinforcing ribs 423 is perpendicular to the center line direction of the rotating connector 43, and the reinforcing ribs 423 are arranged equidistantly along the center line direction of the rotating connector 43.

[0050] Reference Figure 1 Two side baffles 421 are respectively provided on the two wide sides of the guide plate 42, and the side baffles 421 prevent the construction waste from falling outward from the wide sides of the guide plate 42, so that the construction waste on the guide plate 42 falls onto the loading and conveying device 1 as much as possible.

[0051] Reference Figure 4 The end of the buffer cylinder 461 away from the bracket 41 is provided with a sealing plate 464, and the peripheral edge of the sealing plate 464 is provided with a connecting wall 4641, and the connecting wall 4641 is interference-fitted with the inner wall of the buffer cylinder 461. In another embodiment, it can also be set to be threaded. The sealing plate 464 is provided with a through hole 4642 for avoiding the piston rod of the piston 462, and the piston rod of the piston 462 is clearance-fitted with the through hole 4642. The sealing plate 464 blocks the space between the piston rod of the piston 462 and the inner wall of the buffer cylinder 461, reducing the dust from entering the buffer cylinder 461.

[0052] Reference Figure 4A buffer cotton strip 465 is arranged around the piston 462. The material of the buffer cotton strip 465 can be sponge or layered cloth. The peripheral side of the piston 462 is provided with an annular groove 4621 for avoiding the buffer cotton strip 465. The outer peripheral surface of the buffer cotton strip 465 abuts against the inner wall of the buffer cylinder 461, which reduces the air circulation efficiency in the buffer cylinder 461, which is beneficial to improving the buffering effect of the buffer mechanism 46.

[0053] Reference Figure 5 The discharging conveying device 3 includes a discharging conveying belt 31 and a discharging frame 32. The discharging conveying device 3 is gradually inclined upward in the direction away from the crusher 2. An inclined guide plate 6 is fixedly connected to the lower part of the crusher 2. The inclined guide plate 6 is used to guide the crushed construction waste to the discharging conveying belt 31. The lower edge of the inclined guide plate 6 abuts against the working surface of the discharging conveying belt 31. A screening gap 62 is formed between the lower edge of the inclined guide plate 6 and the working surface of the discharging conveying belt 31. The screening gap 62 can screen out the powder and fine particles formed in the process of crushing the construction waste from the side of the discharging conveying belt close to the crusher 2, thereby reducing the dust raised during the feeding process of the discharging conveying belt 31.

[0054] Reference Figure 5 The lower edge of the inclined guide plate 6 is provided with a chamfered surface 61, and the angle formed between the chamfered surface 61 and the working surface of the discharge conveyor belt 31 is oriented in the feeding direction along the discharge conveyor belt 31. The chamfered surface 61 has a guiding effect on the powder and fine particles on the discharge conveyor belt 31, making it easier for the powder and fine particles to pass through the screening gap 62. In addition, by providing the chamfered surface 61, the thickness of the lower edge of the guide plate 42 can be reduced, making it difficult for the powder and fine particles to get stuck in the screening gap 62.

[0055] Reference Figure 5 The discharging frame 32 is fixedly provided with a material shifting piece 7, which is located at one end of the discharging frame 32 close to the crusher 2. When the discharging conveyor belt 31 transports construction waste, the material shifting piece 7 can shift the construction waste on the discharging conveyor belt 31, so that the powder and fine particles remaining in the gaps of the construction waste can fall as much as possible on the discharging conveyor belt 31 and then be sieved out from the screening gap 62.

[0056] Reference Figure 5 A transfer trough 8 is provided at one end of the discharging conveying device 3 close to the crusher 2. The transfer trough 8 is used to receive the construction waste materials sifted out from the screening gap 62. The transfer trough 8 extends downwardly to the top of the auxiliary discharging device 5. The transfer trough 8 transfers the construction waste materials sifted out from the screening gap 62 to the auxiliary discharging device 5, and then is transported through the auxiliary discharging device 5.

[0057] The implementation principle of a construction waste treatment device in an embodiment of the present application is as follows: the transportation equipment unloads the construction waste onto the guide plate 42 of the guide device 4, the guide plate 42 is subjected to the impact of the construction waste, the guide plate 42 is rotated and tilted downward on the side away from the counterweight 44, the buffer mechanism 46 has a buffering effect on the impact of the guide plate 42, and the drop of the construction waste falling to the loading roller 12 is reduced, which is beneficial to reduce the impact of the construction waste on the loading roller 12.

[0058] After the construction waste falls onto the loading conveying device 1, the waste with smaller particle size in the construction waste falls onto the auxiliary conveying device from the screening gap 13 between adjacent loading rollers 12 and is taken away by the auxiliary conveying device; and the main part of the construction waste enters the crusher 2 and falls onto the discharging conveying device 3 along the inclined guide plate 6 after being crushed. The powder and fine particles generated during the crushing process of the construction waste can be screened out through the screening gap 62 between the inclined guide plate 6 and the discharging conveyor belt 31, thereby reducing the formation of dust during the subsequent transportation and screening of the construction waste.

[0059] This embodiment also discloses a construction waste recycling system, which includes the above-mentioned construction waste processing equipment, and the construction waste processing equipment is used in conjunction with the building material production equipment.

[0060] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
