Description

Technical Field

[0001] The utility model belongs to the technical field of asphalt production and processing, and relates to an asphalt production and processing device, in particular to an asphalt production and processing waste material treatment device. Background Art

[0002] Asphalt concrete, commonly known as asphalt concrete, is a mixture of artificially selected mineral materials with a certain graded composition, such as crushed stone or crushed gravel, stone chips or sand, mineral powder, etc., mixed with a certain proportion of road asphalt materials. Asphalt concrete will produce waste during the processing and production process.

[0003] A search revealed a Chinese patent document disclosing a waste treatment device for asphalt concrete processing [Application Number: 202321557741.0; Publication Number: CN220328928U]. This device utilizes a screening mechanism and a sieving mechanism. A hopper and a guide plate direct the crushed asphalt concrete waste to the rear of the screening plate. The inclined screening plate then moves the waste forward, filtering it sequentially through four screens to separate asphalt concrete waste of varying particle sizes.

[0004] Although the screening device disclosed in this patent can process waste materials according to their particle size and optimize the processing structure, the device guides the processed waste materials to fall naturally onto the mesh surface for screening through the guide plate. The friction between the screen and the processed waste materials causes the processed waste materials to remain on the surface of the small-particle screen, which can easily lead to blockage of the processed waste materials of the corresponding particle size, making it difficult to screen them normally and delaying the waste processing process. Utility Model Content

[0005] The purpose of this utility model is to solve the above problems in the existing technology and propose an asphalt production and processing waste treatment device. The technical problem to be solved by this utility model is: how to achieve particle size screening of the crushed waste without clogging.

[0006] The purpose of this utility model can be achieved through the following technical solutions:

[0007] An asphalt production and processing waste treatment device includes a feed box, a crushing device is fixed to the lower inner wall of the feed box, a discharge mechanism is provided at the bottom of the crushing device, and a screening mechanism is provided at the bottom of the discharge mechanism; the screening mechanism includes a screening component and a discharging component, and the screening component includes a discharging box, a motor, a screw, two sliders, four mounting blocks, a scraper, a slide bar, a screen group, two first limit blocks and two second limit blocks, the four mounting blocks are distributed in a matrix, the motor is fixed to one of the mounting blocks on the right, the screw is fixed to the output end of the motor, the four mounting blocks are all fixed to the discharging box, and the screw is rotated to connect Between the two mounting blocks on the left, the slide rod is fixed between the two mounting blocks on the right, one of the sliders is threadedly connected to the screw, and the other slider is sleeved on the slide rod. The scraper is rotated between the two sliders, and the two first limit blocks and the two second limit blocks are symmetrically fixed on the opposite sides of the two sliders. The first limit block is vertically set at the front end of the scraper, and the second limit block is set at the rear end of the scraper. The screen group is set at the bottom of the scraper, the screen group is tilted backward, the screen group is fixed on the inner wall of the discharge box, and the screen group is in contact with the scraper. The discharge assembly is set at the bottom of the screening assembly, and a dust removal mechanism is set on the top of the feed box.

[0008] The working principle of the utility model is as follows: asphalt production and processing waste enters through the feed box and is processed into particles by the crushing equipment. The particles pass through the feeding mechanism to the fine mesh of the screen group, and some of the particles pass through the corresponding particle size screen by natural rolling to achieve screening. For the particles that remain on the surface of the screen group, the running motor drives the screw to rotate the rod, and the slider performs a linear motion in the forward and backward directions with the screw as the trajectory through the thread transmission with the screw and under the limitation of the slide groove and the slide rod, driving the scraper to scrape the waste particles on the surface of the screen group, and the scraper drives the waste particles on the screen. The scraper moves on the surface of the group and passes through the screen of corresponding particle size. When the scraper moves forward, the scraper can rotate by the force relative to the larger waste particles, avoiding scraping more large waste particles to the surface of the small-size screen. When the scraper rotates to be horizontal to the surface of the screen group, it contacts the second limit block and cannot continue to rotate, avoiding the scraper from rotating in a circle. When the scraper moves backward, the scraper is limited by the first limit block and maintains an angle perpendicular to the surface of the screen group in the friction force with the screen group during the movement, thereby pushing the movement of waste particles on the surface of the screen group and preventing the surface of the screen group from being blocked.

[0009] The discharging assembly includes two partitions, which are equidistantly fixed on the bottom of the screen group. The screen group consists of three screens with different densities, and the two partitions are vertically fixed on the inner wall of the discharging box.

[0010] With the above structure, waste particles of different sizes pass through the screen group and enter the space separated between the partitions and the partitions and the discharge box, so that the waste particles passing through the screen group can be separated for easy distinction.

[0011] The bottom of the inner wall of the discharge box is sloped, and both left and right sides of the discharge box are provided with sliding grooves for the slider to slide through.

[0012] With the above structure, after the discharge box door is opened, the separated waste particles slide down through the slope at the bottom of the inner wall of the discharge box and fall into the external waste collection container, thereby accelerating the discharge.

[0013] The unloading mechanism includes a unloading box, a conveyor belt, a material blocking strip and a material blocking plate. The conveyor belt is arranged on the unloading box. The material blocking strip and the material blocking plate are fixed to the inner wall of the unloading box. The material blocking strip is arranged at the rear end of the top of the conveyor belt, and the material blocking plate is arranged at the front end of the bottom of the conveyor belt. The material blocking strip and the material blocking plate are both in contact with the conveyor belt, and the conveyor belt is arranged to be tilted forward.

[0014] With the above structure, the waste particles that have passed through the crushing equipment are transmitted forward through the conveyor belt. The conveyor belt prevents the particles from staying in the discharge box due to friction, ensuring that all the crushed particles are output to the discharge box. The baffle bar prevents the waste particles from falling through the gap between the conveyor belt and the discharge box onto the largest particle size screen in the screen group. The baffle plate scrapes the waste particles in contact with the conveyor belt to the surface of the smallest particle size screen in the screen group, ensuring that the waste particles are screened from small to large particle size screens, thereby ensuring screening accuracy.

[0015] The upper end of the lower material box is fixedly connected and communicated with the feed box, and the bottom end of the lower material box is fixedly connected and communicated with the discharge box.

[0016] With the above structure, waste can enter the feed box, pass through the crushing equipment, the unloading mechanism, the screening component, and the discharge component. There is no blockage in the process, so the waste processing is continuous. There is no need to suspend the feeding in a certain step for maintenance, which improves the waste processing efficiency.

[0017] The dust removal mechanism includes a water tank, a bottom suction water pump, a first metal water pipe, a tee, two hoses, two connecting elbows, two rotating plates, multiple clamps, multiple mist nozzles, two second metal water pipes and two baffles. The two rotating plates and the two baffles form a frame structure. The clamps are fixed on the rotating plates. The second metal water pipe is fixed in the clamps. The mist nozzles are fixed on the second metal water pipes. The bottom suction water pump is arranged on the inner wall of the water tank. One end of the first metal water pipe is fixed to the output end of the bottom suction water pump, and the other end of the first metal water pipe is fixed to the input end of the tee. One end of the hose is fixed to the output end of the tee, and the other end of the hose is fixed to one end of the connecting elbow. The other end of the connecting elbow is fixed to the input end of the second metal water pipe.

[0018] With the above structure, the bottom suction pump sucks the liquid in the water tank, and delivers it to the tee through the first metal water pipe, and then delivers it to two hoses at the same time due to the characteristics of the tee, and then delivers it to the second metal water pipe through the connecting elbow. Finally, it is sprayed in the form of water mist through the mist nozzle to suppress the dust generated during the feeding process. The rotating plate is rotated, and the mist nozzle rotates with the rotating plate through the clamping part. During the rotation of the rotating plate, the connecting elbow moves with the second metal water pipe, and the hose deforms to adapt to the change in the position of the connecting elbow, thereby realizing the adjustment of the water mist spraying range.

[0019] The baffle is fixed to the upper end of the feed box, and the rotating plate is rotatably connected to the feed box via a damping rotating shaft.

[0020] With the above structure, the damping shaft realizes the damping attenuation of the rotation of the rotating plate through the damping material, so that the adjustment angle of the rotating plate has a temporary stop function.

[0021] Compared with the prior art, the utility model has the following advantages:

[0022] 1. The scraper is driven by screw thread to scrape back and forth on the surface of the screen group, so as to drive the waste particles to move on the surface of the screen group instead of the waste particles sliding down for screening, thereby avoiding the friction between the waste particles and the surface of the screen group causing them to stay and cause blockage, affecting the waste treatment process, and improving the waste treatment efficiency.

[0023] 2. By setting up a feeding mechanism, the conveyor belt is used to guide the crushed waste particles to the surface of the smallest particle size screen in the screen group, and the blocking strips and the blocking plates are used to prevent small particles from falling to the surface of the larger particle size screen due to inertial movement, thereby improving the screening accuracy. The guiding speed can be adjusted by adjusting the rotation speed of the conveyor belt, making the feeding speed controllable.

[0024] 3. A rotating plate is set to adjust the range of water mist to adapt to different dust levels. At the same time, connecting elbows, hoses and tees are set to adapt to changes in the position of the mist nozzle. BRIEF DESCRIPTION OF THE DRAWINGS

The conveyor belt 302 prevents the particles from staying in the discharge box due to friction, ensuring that all the crushed particles are output to the discharge box 301.

[0040] The dust removal mechanism 5 includes a water tank 501, a bottom suction water pump 502, a first metal water pipe 503, a tee 504, two hoses 505, two connecting elbows 506, two rotating plates 507, multiple clamps 508, multiple mist nozzles 509, two second metal water pipes 510 and two baffles 511. The two rotating plates 507 and the two baffles 511 form a frame structure. The clamp 508 is fixed on the rotating plate 507. The second metal water pipe 510 is fixed in the clamp 508. The mist nozzle 509 is fixed on the second metal water pipe 510. The bottom suction water pump 502 is arranged on the inner wall of the water tank 501. One end of the first metal water pipe 503 is fixed to the output end of the bottom suction water pump 502, and the other end of the first metal water pipe 503 is fixed to the input end of the tee 504. One end of the hose 505 is fixed to the output end of the tee 504, and the other end of the hose 505 is fixed to the connecting One end of the connecting elbow 506 is connected, and the other end of the connecting elbow 506 is fixed to the input end of the second metal water pipe 510. In this embodiment, the fixed connection is achieved by internal and external threaded connections. The bottom suction pump 502 sucks the liquid in the water tank 501, and transports it to the tee 504 through the first metal water pipe 503. It is simultaneously transported to the two hoses 505 through the characteristics of the tee 504, and is transported to the second metal water pipe 510 through the connecting elbow 506. Finally, it is sprayed in the form of water mist through the mist nozzle 509 to suppress the dust generated during the feeding process. The rotating plate 507 is rotated, and the mist nozzle 509 rotates with the rotating plate 507 through the clamping member 508. During the rotation of the rotating plate 507, the connecting elbow 506 moves with the second metal water pipe 510, and the hose 505 deforms to adapt to the change in the position of the connecting elbow 506 to achieve adjustment of the water mist spraying range.

[0041] The baffle 511 is fixed to the upper end of the feed box 1, and the rotating plate 507 is rotatably connected to the feed box 1 through a damping shaft. In this embodiment, the baffle 511 is integrally formed on the left and right sides of the top of the feed box 1, and the rotating plate 507 is rotatably connected to the front and back sides of the top of the feed box 1 through the damping shaft of the existing technology. The damping shaft realizes damping attenuation of the rotation of the rotating plate through the damping material, so that the adjustment angle of the rotating plate 507 has temporary stopping property.

[0042] The working principle of the present invention is as follows: the waste materials from asphalt production and processing enter through the feed box 1 and are processed into granules by the crushing equipment 2. The waste particles that have passed through the crushing equipment 2 are transported forward by the conveyor belt 302. The conveyor belt 302 prevents the particles from staying in the discharge box due to friction, ensuring that all the crushed particles are output to the discharge box 301. The blocking strip 303 prevents the waste particles from falling through the gap between the conveyor belt 302 and the discharge box 301 onto the largest particle size screen in the screen group 408. The blocking plate 304 scrapes the waste particles in contact with the conveyor belt 302 to the surface of the smallest particle size screen in the screen group 408. Some particles are screened by naturally rolling through the screen of corresponding particle size. For the particles that stay on the surface of the screen group 408, the motor 402 is operated to drive the screw 403 to rotate the rod. The slider 404 is driven by the thread of the screw 403 and is limited by the slide groove and the slide rod 407. It moves linearly in the forward and backward directions with the screw 403 as the track, driving the scraper 406 to scrape the waste particles on the surface of the screen group 408. The scraper 406 drives the waste particles to move on the surface of the screen group 408 and pass through the screen of corresponding particle size. When the scraper 406 moves forward, the scraper 406 can rotate by the force relative to the larger waste particles. , to avoid scraping more large waste particles onto the surface of the small-size screen. When the scraper 406 rotates to be horizontal to the surface of the screen group 408, it contacts the second limit block 411 and cannot continue to rotate, preventing the scraper 406 from rotating in a circle. When the scraper 406 moves backward, the scraper 406 is limited by the first limit block 410 and maintains an angle perpendicular to the surface of the screen group 408 during the movement due to the friction with the screen group 408, thereby pushing the movement of the waste particles on the surface of the screen group 408 and preventing the surface of the screen group 408 from being blocked. During the feeding process, the bottom suction pump 502 sucks the liquid in the water tank 501 through the first metal water The pipe 503 is transported to the tee 504, and is transported to the two hoses 505 at the same time through the characteristics of the tee 504, and is transported to the second metal water pipe 510 through the connecting elbow 506. Finally, it is sprayed in the form of water mist through the mist nozzle 509 to suppress the dust generated during the feeding process. The rotating plate 507 is rotated, and the mist nozzle 509 rotates with the rotating plate 507 through the clamping piece 508. During the rotation of the rotating plate 507, the connecting elbow 506 moves with the second metal water pipe 510, and the hose 505 deforms to adapt to the change in the position of the connecting elbow 506, so as to adjust the water mist spraying range. The water mist plays a dust suppression role in the feeding process.

[0043] In summary, the scraper is driven by thread to scrape back and forth on the surface of the screen group, so that the waste particles are driven to move on the surface of the screen group through operation instead of the waste particles themselves sliding down for screening, thereby avoiding the friction between the waste particles and the surface of the screen group causing them to stay and cause blockage affecting the waste treatment process, thereby improving the waste treatment efficiency.

[0044] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
