DETAILED DESCRIPTION

[0022] The technical solutions of the present application will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of the present application.

[0023] The environment-friendly asphalt resource recycling equipment and method of the present embodiment, as shown in Figure 1 Figure 7 The environment-friendly asphalt resource recycling equipment and method of the present embodiment, as shown in

[0024] In the present embodiment, as shown in Figure 2 The end of the fixed plate 504 close to the vertical groove 3 is fixedly connected with the fixed plate 504, and the fixed plate 504 close to the side of the crushing box 1 is fixedly connected with the torsional spring 503. The end of the torsional spring 503 away from the fixed plate 504 is fixedly connected to the side wall of the crushing box 1, and the torsional spring 503 is sleeved on the outer surface of the rotating shaft 502. When the fixed plate 504 is forced to rotate the rotating shaft 502, the torsional spring 503 is synchronously extruded. When the force disappears, the rebounding force of the torsional spring 503 can drive the fixed plate 504 to rotate in the opposite direction.

[0025] In the present embodiment, as shown in Figure 2 and Figure 4 The end of the fixed plate 504 close to the vertical groove 3 is fixedly connected with the fixed plate 504, and the fixed plate 504 close to the side of the crushing box 1 is fixedly connected with the torsional spring 503. The end of the torsional spring 503 away from the fixed plate 504 is fixedly connected to the side wall of the crushing box 1, and the torsional spring 503 is sleeved on the outer surface of the rotating shaft 502. When the fixed plate 504 is forced to rotate the rotating shaft 502, the torsional spring 503 is synchronously extruded. When the force disappears, the rebounding force of the torsional spring 503 can drive the fixed plate 504 to rotate in the opposite direction.

[0026] In the present embodiment, as shown in Figure 4 , Figure 6 and​Figure 7 As shown, the lifting plate 507 is rotatably connected with a connecting plate 508 at the center of the side of the crushing box 1 away from the lifting plate 507, and the connecting plate 508 is rotatably connected with a moving block 509 at the side of the connecting plate 508 away from the lifting plate 507. The moving block 509 is slidably connected in the horizontal groove 4, and a driven pulley 512 is symmetrically arranged below the moving block 509. The driven pulley 512 is rotatably connected to the side wall of the crushing box 1, and a belt 513 is sleeved on the outer surface of the driven pulley 512. A push plate 514 is fixedly connected to the outer surface of the belt 513, and the push plate 514 is used to push the moving block 509 to move. When the belt 513 moves around the driven pulley 512, the belt 513 can drive the push plate 514 to push the moving block 509 to slide synchronously in the horizontal groove 4. At this time, the moving block 509 will pull the lifting plate 507 to slide downward synchronously in the vertical groove 3 during the movement of the moving block 509 through the connecting plate 508 rotatably connected to the side wall.

[0027] In this embodiment, as shown in Figure 7 The inner center of the belt 513 is drivingly connected with a main pulley 516, and the main pulley 516 is fixedly connected to the outer surface of the drive shaft 515. When the drive shaft 515 drives the main pulley 516 to rotate, the belt 513 can be driven to move. Through the transmission connection of the belt 513 and the driven pulley 512, the driven pulley 512 can be driven to rotate.

[0028] In the prior art, the crushing device usually adopts an open type or a manually closed structure, which causes the dust, asphalt smoke and other harmful gases generated during the operation to directly escape to the external environment, seriously pollutes the air and harms the health of the operators, and is difficult to meet the increasingly stringent environmental emission limit requirements. In addition, due to the lack of effective automatic closing device, foreign matter and sundries are easily fallen into the crushing box 1 to pollute the asphalt recycling material during the production process, which affects the purity and grading stability of the recycled mixture. Furthermore, the open structure cannot block the mechanical noise generated during the operation of the equipment, resulting in a poor sound environment in the operation area. Compared with the prior art, the crushing box 1 can automatically close the top of the crushing box 1 during the crushing and recycling of asphalt, which not only isolates the internal dust and harmful gases from diffusing to the external environment, reduces air pollution from the source, protects the health of the operators, and meets the environmental emission limit requirements, but also avoids the pollution of foreign matter or sundries to the asphalt material during the operation process, ensures the purity and stability of the recycled mixture, and blocks the mechanical noise generated during the crushing process, thereby improving the sound environment quality in the operation area.

[0029] On other levels, the embodiment also provides a dust removal mechanism for concentrating and collecting the dust inside the crushing box 1, as shown in Figure 3 Figure 6 ​As shown, the dust removal mechanism includes an exhaust fan 608, which is fixedly connected to the drive shaft 515. The exhaust fan 608 is located inside the crushing box 1. A protective shell 607 is fitted on the outer surface of the exhaust fan 608. A ventilation hole 611 is provided on the side of the crushing box 1 near the exhaust fan 608. An adsorption plate 606 is fixedly connected to the inner wall of the crushing box 1 away from the exhaust fan 608. An inclined plate 609 is provided below the adsorption plate 606 and is fixedly connected to the inner wall of the crushing box 1.

[0030] In this embodiment, as Figure 3 and Figure 5 As shown, a discharge port 605 is provided on the side of the crushing box 1 near the adsorption plate 606, and the discharge port 605 is located below the adsorption plate 606. A water storage tank 601 is fixedly connected to the side of the crushing box 1 near the discharge port 605, and the water storage tank 601 is located below the discharge port 605. A filter plate 602 is fixedly connected to the upper surface of the water storage tank 601. A water pump 604 is fixedly connected to the side of the water storage tank 601 away from the crushing box 1. A water supply pipe 603 is fixedly connected to the water pump 604 and passes through and is fixedly connected to the crushing box 1 to supply water. A diversion pipe 610 is fixedly connected to the end of pipe 603 away from the water pump 604. The diversion pipe 610 is located above the adsorption plate 606. When the water pump 604 is turned on to draw water from the water storage tank 601 and discharge it through the water supply pipe 603 and the diversion pipe 610, the water will flow from top to bottom along the side wall of the adsorption plate 606 to wash the side wall of the adsorption plate 606. The water that comes into contact with the dust will be discharged through the inclined plate 609 and the discharge port 605 and flow to the filter plate 602 to filter the water.

[0031] Compared with existing technologies, the exhaust fan 608 can be driven simultaneously during the intermittent opening of the baffle 501 to blow the dust inside the crushing box 1 onto the adsorption plate 606 on the other side. This not only collects the dust in time to prevent it from settling in the crushing box 1 and reducing abrasive wear on moving parts, but also helps to reduce dust leakage, lower the dust concentration in the work area, improve the working environment for operators, and reduce the potential harm of dust to the respiratory system.

[0032] At other levels, this embodiment also provides an environmentally friendly method for the resource recycling of asphalt, such as... Figure 1 - Figure 7 As shown, it includes the following steps: Step 1: Put the asphalt blocks into the crushing equipment for crushing and processing; Step 2: During the crushing process, dust control measures are implemented to prevent the dust generated during crushing from escaping. Step 3: During the crushing process, a dust removal operation is performed to collect and treat the dust generated inside the equipment; Step 4: The asphalt material that has completed crushing and dust treatment is discharged from the equipment and enters the subsequent resource recycling process.

[0033] In this embodiment, the dust prevention operation in step 2 is achieved by the movable baffle 501 mechanism at the feed inlet of the equipment.

[0034] In this embodiment, the dust removal operation in step 3 is achieved by spraying liquid into the equipment and then exporting the dust-laden liquid.

[0035] The overall working process and principles involved in the above embodiments are as follows: When workers need to crush and recycle asphalt, they first turn on the drive motor 511, which drives the drive shaft 515 to rotate. This causes the main pulley 516 connected to the outer surface of the drive shaft 515 to rotate synchronously. Since a belt 513 is fitted onto the outer surface of the main pulley 516, and driven pulleys 512 are symmetrically connected inside the belt 513, the rotation of the main pulley 516 drives the driven pulleys 512 on both sides to rotate synchronously via the belt 513. This causes the belt 513 to rotate around the main pulley 516 and the driven pulleys 512. 2. As the outer surface moves, the lever 514, which is fixedly connected to the outer surface of the belt 513, will move synchronously with the belt 513. When the lever 514 moves to the top, it will gradually approach the moving block 509. After the lever 514 and the moving block 509 come into contact, as the lever 514 continues to move, it will push the moving block 509 to slide horizontally in the transverse groove 4 opened on the side wall of the crushing box 1. Since the connecting plate 508 is rotatably connected to the side wall of the moving block 509, the side of the connecting plate 508 away from the moving block 509 rotates. Connected to the lifting plate 507, which is slidably connected within the vertical groove 3, the connecting plate 508 moves from a vertical position to a near-horizontal position as the moving block 509 slides horizontally. As the state of the connecting plate 508 changes, it causes the lifting plate 507 to slide vertically downwards within the vertical groove 3. At this time, the linkage column 506, fixedly connected to the side wall of the lifting plate 507, descends synchronously. The linkage column 506 is slidably connected to the fixed plate 504 via the through groove 505. The fixed plate 504 is fixedly connected to the rotating shaft 5. Therefore, when the linkage column 506 slides downward, it will slide synchronously in the through groove 505 opened on the fixed plate 504. The through groove 505 will push one end of the fixed plate 504 to move downward, causing the rotating shaft 502 connected to the fixed plate 504 to rotate on the crushing box 1. This will cause the baffle 501 connected to the outer surface of the rotating shaft 502 to rotate downward and open. At the same time, the fixed plate 504 will squeeze the torsion spring 503 connected to the outer surface of the rotating shaft 502. At this time, the staff can put the asphalt into the crushing box 1 for crushing. When the belt 513 drives the lever 514 from top to bottom, the lever 514 will separate from the moving block 509. At this time, through the rebound force of the torsion spring 503, the torsion spring 503 will push the fixed plate 504 to drive the rotating shaft 502 to reverse, so that the baffles 501 connected to the upper end of the crushing box 1 will come closer to each other and close. This not only isolates the internal dust and harmful gases from spreading to the external environment, reducing air pollution from the source, protecting the health of operators, and meeting the environmental emission limit requirements, but also prevents foreign objects or debris from falling into the crushing box 1 during the operation and contaminating the asphalt material, ensuring the purity and stability of the recycled mixture. In addition, the closed structure can block the mechanical noise generated during the crushing process and improve the sound environment quality of the working area. When the fixed plate 504 reverses due to the rebound force of the torsion spring 503, the fixed plate 504 will move the linkage column 506 through the through groove 505, causing the lifting plate 507 to rise in the vertical groove 3. At this time, the lifting plate 507 will pull the moving block 509 to move in the opposite direction in the horizontal groove 4 through the connecting plate 508, sliding back to the initial position, so that the subsequent moving plate 514 can move the moving block 509 again. This allows the baffles 501 symmetrically connected to the upper end of the crushing box 1 to open intermittently and automatically. It can open and close automatically according to the preset rhythm without manual intervention, accurately control the material feed amount and feeding time, prevent the equipment from overload or idling, and improve crushing efficiency and stability. Moreover, the baffles 501 automatically close during non-feeding periods, minimizing the open time of the crushing box 1, continuously suppressing the leakage of dust and harmful gases, and reducing air pollution from the source. During the rotation of the drive shaft 515 driven by the drive motor 511, the exhaust fan 608 fixedly connected to the drive shaft 515 will rotate synchronously to form an airflow, which blows the dust generated during the crushing process inside the crushing box 1 onto the adsorption plate 606 connected to the inner wall of the crushing box 1. This not only collects the dust in time to prevent it from settling in the crushing box 1 and reducing abrasive wear on moving parts, but also helps to reduce dust leakage, reduce the dust concentration in the working area, improve the working environment of operators, and reduce the potential harm of dust to the respiratory system. While the drive motor 511 is in operation, the operator can simultaneously turn on the water pump 604 to draw water from the water storage tank 601 into the water delivery pipe 603, and then deliver it to the diversion pipe 610. The water is then discharged through the diversion pipe 610. Since the diversion pipe 610 is located above the adsorption plate 606, and an inclined plate 609 is installed below the adsorption plate 606 and fixedly connected to the discharge port 605, as the diversion pipe 610 discharges water, the water flows downwards along the side wall of the adsorption plate 606, washing away the dust on the adsorption plate 606. The water containing dust falls onto the inclined plate 609 below and flows down the inclined surface of the inclined plate 609 to the discharge port. At outlet 605, the water is discharged through discharge port 605. Since water storage tank 601 is located below discharge port 605 and filter plate 602 is installed on the upper surface of water storage tank 601, when water containing dust is discharged through discharge port 605, it will flow to the top of filter plate 602. After being filtered by filter plate 602, the dust will remain on the surface of filter plate 602, while the water will continue to flow into water storage tank 601 for recycling. This process not only requires no manual intervention, improving the automation of dust cleaning, but also the design of filter plate 602 can filter out dust particles in the water flow, allowing the cleaning water to be recycled, saving water resources, reducing wastewater discharge, and meeting environmental protection requirements.
