Description

Technical Field

[0001] This utility model belongs to the field of tailings solid waste crushing and sorting technology, specifically relating to a tailings solid waste soil improvement pretreatment crushing and sorting device. Background Technology

[0002] Resource utilization of solid waste such as tailings, construction waste, and industrial sludge (hereinafter referred to as "solid waste") is an important link in achieving sustainable development. Among them, crushing and sorting such solid waste and using it as soil amendment materials or roadbed soil is an effective resource utilization approach. In this process, pretreatment is a key step, the core of which is to crush large pieces of solid waste to a suitable particle size through crushing and sorting devices.

[0003] When crushers break materials into small pieces, they generate a large amount of dust. This dust permeates the area around the equipment, causing serious air pollution and posing a threat to the health of operators. The crushed material falls onto an inclined vibrating screen for sorting. Existing devices cannot adjust the screen's inclination angle according to the different materials to be sorted. For example, in construction waste, there is a mixture of bricks and concrete. Bricks have a low density and relatively loose texture, and after crushing, they are mostly irregular particles. If the inclination angle of the vibrating screen is too large, the brick particles will slide quickly due to gravity. Even if the particle size meets the requirements, they do not have time to pass through the screen holes and are eventually discharged with large pieces of concrete residue, resulting in a significant reduction in the recovery rate of useful materials. When processing fine-grained tailings, if the screen inclination angle is too small, the tailings particles, due to their high density and tendency to agglomerate, will slowly accumulate on the screen surface, not only clogging the screen holes but also significantly reducing the sorting speed and severely slowing down the entire pretreatment process.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in related technologies, this utility model proposes a tailings solid waste soil improvement pretreatment crushing and sorting device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a tailings solid waste soil improvement pretreatment crushing and sorting device, including a bottom shell, a sorting mechanism rotatably installed inside the bottom shell, the sorting mechanism including a bottom frame, the front of the bottom frame rotatably installed on the inner wall of the bottom shell, through holes symmetrically opened at both ends of the back of the bottom frame, and arc plates fixedly installed at both the left and right ends of the bottom shell, the arc plates having a plurality of threaded holes, and the plurality of threaded holes being distributed in a circular array with the central axis of the arc plates as the center, and a plug being installed in each through hole; A crushing box is fixedly installed on the top of the bottom shell, and a crushing mechanism is installed inside the crushing box; The bottom shell is hinged to the top of the cover, and a connecting box is installed on the inner wall of the cover. The connecting box has a cavity inside and several dust inlet holes on the inner wall of the connecting box. A corrugated telescopic tube is connected to the top of the connecting box, and a collection box is connected to the end of the corrugated telescopic tube away from the connecting box. A blocking net is installed on the inner wall of the collection box by a magnetic attachment, and a fan is installed at the front of the collection box and on one side of the blocking net. A hopper is fixedly installed on the inner wall of the bottom shell and below the bottom frame, and a controller is installed at one end of the bottom shell.

[0007] Furthermore, the sorting mechanism also includes four vibration springs, which are distributed at the four corners of the top of the bottom frame, and a vibration frame is fixedly installed at the end of each vibration spring away from the bottom frame.

[0008] Furthermore, a vibration motor is installed at one end of the vibration frame, a screen is fixedly installed at the top of the vibration frame, a frame plate is fixedly installed on the outer periphery of the top of the vibration frame, and an inclined chute is fixedly installed at the front end of the vibration frame.

[0009] Furthermore, the plug-in includes a screw, one end of which is fixedly fitted with a knurled knob.

[0010] Furthermore, the crushing mechanism includes a drive motor, which is fixedly mounted on the crushing box. A drive gear is fixedly mounted on the output end of the drive motor, and a rotating shaft is fixedly mounted on the axis of the drive gear. Several first crushing blades are installed on the outer wall of the rotating shaft and located in the inner cavity of the crushing box.

[0011] Furthermore, one end of the driving gear meshes with a driven gear, and a connecting shaft is fixedly installed at the axis of the driven gear. The connecting shaft is rotatably installed with the crushing box, and a plurality of second crushing blades are fixedly installed on the outer wall of the connecting shaft and in the inner cavity of the crushing box. The plurality of first crushing blades and the plurality of second crushing blades are distributed at intervals.

[0012] Furthermore, a door shell is symmetrically hinged to the back of the bottom shell.

[0013] This utility model has the following beneficial effects: This invention involves rotating the base frame to adjust the screen's tilt angle, aligning the two through holes with the threaded holes on the nearest curved plate, and then inserting the two screws through the through holes. The knurling knob is then manually rotated, causing the screws to rotate and thus screw them into the threaded holes. At this point, the screws provide support for the base frame, completing the adjustment of the screen's tilt angle. This adapts to the sorting needs of different materials, increasing the device's versatility.

[0014] This invention allows the operator to rotate the cover to cover the opening at the top of the crushing chamber. At the same time, the controller starts the fan, creating a negative pressure suction force inside the collection chamber. The connected corrugated telescopic tube and the cavity also generate suction force. The dust generated during crushing enters the cavity through several dust inlets, passes through the corrugated telescopic tube, and is finally collected in the collection chamber. This prevents the dust generated during material crushing from spreading around the equipment and posing a threat to the health of the operator.

[0020] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0021] Please see Figures 1-9 As shown, this utility model is a tailings solid waste soil improvement pretreatment crushing and sorting device, including a bottom shell 1. A sorting mechanism 2 is rotatably installed inside the bottom shell 1. The sorting mechanism 2 includes a bottom frame 201. The front of the bottom frame 201 is rotatably installed on the inner wall of the bottom shell 1. Through holes 202 are symmetrically opened at both ends of the back of the bottom frame 201. Arc plates 3 are fixedly installed at both the left and right ends of the bottom shell 1. A plurality of threaded holes 301 are opened in the arc plates 3, and the plurality of threaded holes 301 are distributed in a circular array with the central axis of the arc plates 3 as the center. A plug 4 is installed in each through hole 202. A crushing box 12 is fixedly installed on the top of the bottom shell 1, and a crushing mechanism 5 is installed inside the crushing box 12; The bottom shell 1 is hinged to the top of the cover 6. The inner wall of the cover 6 is fitted with a connecting box 7. The connecting box 7 has a cavity 701 inside. The inner wall of the connecting box 7 has several dust inlet holes 702. The top of the connecting box 7 is connected to a corrugated telescopic tube 8. The end of the corrugated telescopic tube 8 away from the connecting box 7 is connected to a collection box 9. The inner wall of the collection box 9 is fitted with a blocking net 10 through a magnetic suction component 15. A fan 11 is installed at the front end of the collection box 9 and on one side of the blocking net 10. A hopper 13 is fixedly installed on the inner wall of the bottom shell 1 and below the bottom frame 201.

[0022] First, the tilt angle of the sorting mechanism 2 needs to be adjusted according to the material to be crushed. The operator holds the bottom frame 201. Since one end of the bottom frame 201 is rotatably mounted on the inner wall of the bottom shell 1, the bottom frame 201 is rotated around the connection point of the two as the axis of rotation. After adjusting to the required tilt angle, the two through holes 202 on the bottom frame 201 are aligned with the threaded holes 301 on the arc plate 3 that are closest to this height. It should be noted that the distance between the threaded holes 301 on the arc plate 3 is small and will not affect the adjustment of the angle of the sorting mechanism 2. Then, the two inserts 4 are passed through the two through holes 202 and screwed into the threaded holes 301. This will support the bottom frame 201 and complete the adjustment of the tilt angle of the sorting mechanism 2. This adapts to the sorting requirements of different materials and increases the adaptability of the device. Next, the crushing mechanism 5 is started via controller 16. The material to be crushed is placed onto the crushing mechanism 5 inside the crushing box 12. The crushing mechanism 5 generates a large amount of dust during operation. The operator can rotate the cover 6 to cover the opening at the top of the crushing box 12 to prevent dust from overflowing. Simultaneously, controller 16 starts the blower 11 (model YN5-47). The air inlet of the blower 11 is connected to the collection box 9. After the blower 11 starts, it creates a negative pressure suction force inside the collection box 9, which in turn creates suction force in the connected corrugated telescopic pipe 8 and the cavity 701, thus crushing the material. The dust generated will enter the cavity 701 through several dust inlet holes 702 on the connecting box 7, and then pass through the corrugated telescopic tube 8, and finally be collected in the collection box 9. This prevents the dust generated during material crushing from spreading around the equipment and posing a threat to the health of the operators. The baffle 10 between the collection box 9 and the fan 11 can prevent dust from entering the fan 11. If the baffle 10 needs to be replaced, simply apply a force greater than that of the magnetic suction part 15 (preferably a magnet with a stronger attraction force). The baffle 10 is made of iron. The baffle 10 can be removed from the magnetic suction part 15. While the crushing operation is in progress, the controller 16 will control the sorting mechanism 2 to start vibrating. The crushed material will fall onto the sorting mechanism 2 and be sorted by the vibration force of the sorting mechanism 2. The material with the required particle size will pass through the sorting mechanism 2 and fall into the feed hopper 13 below. The material with the required particle size will not be able to pass through the sorting mechanism 2 and will slide along the inclined surface of the sorting mechanism 2 and eventually fall to the ground.

[0023] In one embodiment, the sorting mechanism 2 further includes four vibration springs 203, which are distributed at the four corners of the top of the bottom frame 201. A vibration frame 204 is fixedly installed at one end of each vibration spring 203 away from the bottom frame 201.

[0024] A vibration motor 205 is installed at one end of the vibration frame 204, a screen 206 is fixedly installed on the top of the vibration frame 204, a frame plate 207 is fixedly installed on the outer periphery of the top of the vibration frame 204, and an inclined chute 208 is fixedly installed at the front end of the vibration frame 204.

[0025] The controller 16 is electrically connected to the vibration motor 205 (model MVE60 / 3). The controller 16 controls the vibration motor 205 to start. The high-frequency vibration power generated by the vibration motor 205 is directly transmitted to the vibration frame 204, causing the entire vibration frame 204 to vibrate regularly with the vibration spring 203 as support. It is important to note that there is a gap between the vibration frame 204 and the bottom shell 1, so that the vibration frame 204 does not contact the inner wall of the bottom shell 1 when it vibrates. At this time, the screen 206 fixed on the top of the vibration frame 204 will vibrate synchronously with the vibration frame 204, and the material that falls onto the screen 206 after being crushed will... Under the vibration of the screen 206, the particles will slide slightly along the surface of the screen 206. Particles that meet the aperture requirements of the screen 206 will pass through the mesh of the screen 206 during the vibration and fall into the hopper 13 below. Particles that do not meet the aperture requirements of the screen 206 will remain on the surface of the screen 206 and move along the inclined direction of the screen 206 towards the inclined chute 208, and fall to the ground through the inclined chute 208. The frame plate 207 fixed on the top periphery of the vibrating frame 204 can prevent the material from falling from the edge of the vibrating frame 204.

[0026] The plug-in 4 includes a screw 401, and a knurled knob 402 is fixedly installed at one end of the screw 401.

[0027] After the screw 401 passes through the through hole 202, the knurled knob 402 is turned by hand. The knurled knob 402 drives the screw 401 to rotate, thereby screwing the screw 401 into the threaded hole 301. At this time, the screw 401 supports the bottom frame 201.

[0028] In one embodiment, the crushing mechanism 5 includes a drive motor 501, which is fixedly mounted on the crushing box 12. A drive gear 502 is fixedly mounted on the output end of the drive motor 501. A rotating shaft 503 is fixedly mounted on the axis of the drive gear 502. A plurality of first crushing blades 504 are mounted on the outer wall of the rotating shaft 503 and located in the inner cavity of the crushing box 12.

[0029] One end of the driving gear 502 is meshed with a driven gear 505. A connecting shaft 506 is fixedly installed at the axis of the driven gear 505. The connecting shaft 506 is rotatably installed with the crushing box 12. A plurality of second crushing blades 507 are fixedly installed on the outer wall of the connecting shaft 506 and in the inner cavity of the crushing box 12. A plurality of first crushing blades 504 and a plurality of second crushing blades 507 are distributed at intervals.

[0030] When the controller 16 is electrically connected to the drive motor 501 (drive motor 501 model: YE3-100L1-4), the controller 16 controls the drive motor 501 to start, and the output end of the drive motor 501 synchronously drives the drive gear 502 to rotate. At the same time, a rotating shaft 503 is fixedly installed at the axis of the drive gear 502. The rotating shaft 503 rotates with the drive gear 502, and the rotating shaft 503 drives several first crushing blades 504 to rotate in the inner cavity of the crushing box 12. Secondly, since one end of the driving gear 502 meshes with the driven gear 505, when the driving gear 502 rotates, it drives the driven gear 505 to rotate in the opposite direction. A connecting shaft 506 is fixedly installed on the axis of the driven gear 505, and several second crushing blades 507 are fixed on the outer wall of the connecting shaft 506. At this time, the rotational power of the driven gear 505 is transmitted to the second crushing blades 507 through the connecting shaft 506, causing the second crushing blades 507 to rotate in the opposite direction with the connecting shaft 506. Finally, when the material to be crushed is put into the crushing box 12, the rotating first crushing blades 504 and the counter-rotating second crushing blades 507 can exert a shearing force on the material, crushing it into fine particles. The crushed particles will fall from the discharge port at the bottom of the crushing box 12 under the action of gravity and fall onto the screen 206.

[0031] In one embodiment, for the aforementioned bottom shell 1, a door shell 101 is symmetrically hinged to the back of the bottom shell 1.

[0032] Rotate the two door shells 101 to open the space on the side of the bottom shell 1 that needs to be rotated, so that the operator can adjust the tilt angle of the bottom frame 201. After adjustment, close the two door shells 101 and lock them.

[0033] Working principle: Rotate the two door shells 101 to open the space of the bottom shell 1 on the side of the bottom frame 201 that needs to be rotated. One end of the bottom frame 201 is rotated and installed on the bottom shell 1. Rotate the bottom frame 201 with the connection point of the two as the axis of rotation. After adjusting to the required tilt angle of the screen 206, align the two through holes 202 on the bottom frame 201 with the threaded holes 301 on the arc plate 3 that is closest to this height. Then, pass the two screws 401 through the through holes 202 and turn the knurled knob 402 by hand. The knurled knob 402 drives the screws 401 to rotate, thereby screwing the screws 401 into the threaded holes 301. At this time, the screws 401 support the bottom frame 201 and complete the adjustment of the tilt angle of the screen 206. Next, the controller 16 controls the drive motor 501 to start. The drive motor 501 drives the drive gear 502, the rotating shaft 503 and the first crushing blade 504 to rotate in the inner cavity of the crushing box 12. When the drive gear 502 rotates, it drives the driven gear 505, the connecting shaft 506 and several second crushing blades 507 to rotate in the opposite direction. When the material to be crushed is put into the crushing box 12, the rotating first crushing blades 504 and the rotating second crushing blades 507 can form a shearing force on the material, crushing it into fine particles. The crushed particles will fall onto the screen 206 under the action of gravity. During the crushing process, a large amount of dust is generated. The operator can rotate the cover 6 to cover the opening at the top of the crushing box 12. At the same time, the controller 16 starts the fan 11 to create a negative pressure in the collection box 9. The connected corrugated telescopic pipe 8 and the cavity 701 also generate suction. The dust generated by crushing will enter the cavity 701 through several dust inlet holes 702, and then pass through the corrugated telescopic pipe 8 before finally being collected in the collection box 9. The controller 16 controls the vibration motor 205 to start. The high-frequency vibration generated by the vibration motor 205 is transmitted to the vibration frame 204, causing the entire vibration frame 204 to vibrate regularly with the vibration spring 203 as support. At this time, the screen 206 will vibrate with the vibration frame 204. The material that falls onto the screen 206 after being crushed will slide slightly along the surface of the screen 206 under the action of vibration. Particles that meet the requirements of the screen 206 aperture will pass through the mesh of the screen 206 during the vibration and fall into the feed hopper 13 below. Particles that do not meet the requirements of the screen 206 aperture will remain on the surface of the screen 206 and move along the inclined direction of the screen 206 towards the inclined chute 208, and fall to the ground through the inclined chute 208.
