Description

Technical Field

[0001] The present invention belongs to the technical field of solid waste treatment, and in particular relates to a solid waste treatment device. Background Art

[0002] When treating solid waste, it is usually necessary to first crush the solid waste to reduce the volume or length of the solid waste so that subsequent treatment work can be carried out.

[0003] At present, the solid waste crusher on the market has relatively complete functions and a relatively mature structure. Usually, a motor drives two rollers to rotate, and teeth are installed on the rollers. Through the synchronous reverse rotation of the two rollers, the teeth on the rollers bite the solid waste and crush the solid waste. In addition, the crusher in the prior art is equipped with a material-stuck reversal mechanism, that is, when the teeth on the rollers cannot crush the solid waste and cause material jamming, the torque sensor on the rollers generates a signal and feeds it back to the electric control cabinet, which controls the motor to rotate slightly in the opposite direction, so that the rollers reverse, bite the solid waste again, and then crush it again.

[0004] Although the crusher in the prior art can re-grip the solid waste by reversing, if the position of the solid waste on the roller is special, for example, when the larger end of the solid waste is located exactly between the two corresponding teeth of the two rollers, even after the roller is reversed, when the teeth on the roller bite the solid waste, since the larger end of the solid waste is usually thicker, the teeth on the roller are still prone to jamming when crushing the end, and manual adjustment is required, which makes the operation inconvenient. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a solid waste treatment device.

[0006] The technical solution adopted to solve the above technical problems is: a solid waste treatment equipment, including a frame and two rollers symmetrically installed on the frame, the two rollers are driven by a driving mechanism arranged on the frame to rotate synchronously in opposite directions, the lower side of the frame is surrounded by a discharge port, and also includes: A mounting portion fixedly sleeved on the periphery of the roller shaft at equal intervals, wherein the periphery of the mounting portion is provided with a plurality of assembly openings in the form of notches along its axial array; A gear block fixedly connected to the assembly opening, wherein a non-working surface of the gear block is provided with a concave receiving groove; A movable block engaged in the receiving groove, wherein the movable block slides freely in the receiving groove; A movable mechanism is arranged in the tooth block, and the movable mechanism is used to drive the movable block to move in the accommodating groove.

[0007] Through the above technical solution, when the material is stuck, the driving mechanism drives the roller to rotate slightly in the opposite direction, so that the solid waste produces pressure on the movable block. Under the action of pressure, the movable mechanism drives the movable block to move horizontally, thereby driving the solid waste to move horizontally slightly, thereby adjusting the position of the solid waste on the mounting portion so that the tooth block can bite the solid waste. In addition, if the tooth block still gets stuck, the above steps can be repeated automatically until the tooth block can bite the solid waste and crush the solid waste.

[0008] Furthermore, the driving mechanism includes a motor installed on the placement surface, a reduction gearbox is provided on the outside of the frame, a motor shaft of the motor is drivingly connected to the reduction gearbox, one of the roller shafts is drivingly connected to the reduction gearbox, a gear transmission unit is provided on one side of the frame, and two of the roller shafts are connected to the gear transmission unit.

[0009] Through the above technical solution, the motor drives the reduction box to rotate, the reduction box drives one of the rollers to rotate, and then drives the other roller to rotate synchronously in the opposite direction through the gear transmission unit, so that the two rollers rotate synchronously in the opposite direction, so that the gear blocks on the mounting plates of the two rollers can crush the solid waste thrown between the two rollers.

[0010] Furthermore, an electric control cabinet is provided on the frame, a torque sensor is installed on one of the rollers, and the motor and the torque sensor are both electrically connected to the electric control cabinet.

[0011] Through the above technical solution, the torque sensor collects the torque of the roller and feeds it back to the electric control cabinet. When the roller torque collected by the torque sensor increases, the electric control cabinet will control the motor to rotate in the opposite direction, thereby driving the two rollers to rotate in the opposite direction, thereby pushing out the solid waste stuck between the two rollers.

[0012] Furthermore, a feeding port is provided on the upper side of the frame.

[0013] Through the above technical solution, solid waste can be fed into between the two rollers through the feeding port.

[0014] Furthermore, the movable mechanism includes a support shaft horizontally inserted through the tooth block, the outer wall of the movable block is provided with a clearance groove for the support shaft to pass freely, a sliding pin is fixed to the periphery of the support shaft, and a waist-shaped hole for the sliding pin to be inserted into the surface of the movable block is provided, and the length direction of the waist-shaped hole forms an angle with the axial direction of the support shaft, and a return spring is wound around each of the two ends of the support shaft, and the two ends of the return spring in the elastic force direction correspondingly elastically press against the outer wall of the movable block and the inner wall of the accommodating groove.

[0015] Through the above technical solution, when the solid waste is bitten by the tooth blocks on the two rollers, the solid waste's own gravity and the longitudinal component of the tooth block's squeezing force on the solid waste act together on the movable block, so that the movable block is subjected to a force in the direction of retracting into the inner side of the accommodating groove, thereby causing the sliding pin to slide in the waist-shaped hole, so that the sliding pin slides from the lower side of the waist-shaped hole in the length direction to the upper side of the waist-shaped hole in the length direction, thereby causing the movable block to move horizontally, and one of the return springs is squeezed by the movable block to accumulate elastic potential energy. In addition, since the solid waste is bitten by the tooth block at this time, the solid waste will not move horizontally. When the solid waste cannot When the material is broken by the tooth block and jammed, the roller will rotate in the opposite direction of the original rotation direction, causing the movable block to rotate in the opposite direction. At this time, the biting force of the tooth block on the solid waste is reduced. At the same time, since the solid waste moves upward on the periphery of the mounting portion, the elastic potential energy of the reset spring is released, causing the movable block to move in the opposite direction. The sliding pin will slide from the upper side to the lower side in the length direction of the waist-shaped hole, so that the movable blocks on multiple tooth blocks can lift the solid waste together. Since the movable blocks move horizontally at the same time, the solid waste can be driven to move horizontally. In this way, the position of the solid waste on the tooth block can be changed. The structure is simple and automatic operation can be achieved.

[0016] Furthermore, a plurality of stripe grooves are provided on a side of the movable block that is exposed from the tooth block.

[0017] Through the above technical solution, the striped grooves are arranged so that when the movable block moves horizontally, the friction between the surface of the movable block and the surface of the solid waste is relatively large, thereby being able to smoothly drive the solid waste to move horizontally.

[0018] Furthermore, the length direction of the striped groove is perpendicular to the axial direction of the mounting portion.

[0019] Through the above technical solution, the friction between the surface of the movable block and the surface of the solid waste is relatively large.

[0020] Furthermore, the mounting portion is key-connected to the periphery of the roller shaft, and a spacing self-adjusting mechanism is provided on the frame. The spacing self-adjusting mechanism is used to drive the mounting portion to translate along a fixed direction when two corresponding tooth blocks on the two roller shafts approach each other, so that the lateral spacing between two adjacent mounting portions increases.

[0021] Through the above technical solution, after the tooth block cuts off the longer solid waste, the length or width of the cut solid waste may be greater than the lateral spacing between two adjacent mounting portions on the same roller, which may cause the cut solid waste to be stuck between two adjacent mounting portions on the same roller, resulting in it being unable to fall smoothly. Therefore, through the spacing self-adjusting mechanism, after the tooth block cuts and crushes the solid waste, the spacing between two adjacent mounting portions on the same roller is increased, so that the cut solid waste can fall smoothly between the two adjacent mounting portions.

[0022] Furthermore, the spacing self-adjusting mechanism includes a fixed plate fixedly connected to the inner wall of one side of the frame, and two fixed seats are fixedly connected to the inner wall of one side of the frame away from the fixed plate, and the fixed seat and the fixed plate are each rotatably connected with a rotating seat, and the two rotating seats at the axial ends of the same roller shaft are rotatably connected to the two rotating shafts together, and two nut sleeves are embedded on the end face of the mounting portion, and the periphery of the rotating shaft is fixedly sleeved with an external thread sleeve, and the external thread sleeve is correspondingly threaded through the nut sleeve, and the thread pitch of the multiple external thread sleeves on the same rotating shaft decreases successively in the direction away from the fixed seat, and a rotation driving unit is provided in the fixed seat for driving the rotating shaft to rotate around its own axis when the roller shaft rotates.

[0023] Through the above technical scheme, when the roller shaft rotates, it will synchronously drive the two rotating seats on both sides of its axis to rotate. When the rotating seat rotates, it will cause the two rotating shafts to rotate around the axis of the roller shaft. During rotation, the rotating drive unit will intermittently drive the rotating shaft to rotate, so that the nut sleeve and the external thread sleeve are threaded together, and then the nut sleeve drives the mounting part to produce horizontal movement. In addition, since the thread pitch of the external thread sleeve decreases successively, the movement stroke of each mounting part is changed successively, so that the spacing between the multiple mounting parts on the roller shaft can be increased, avoiding the phenomenon that the movement stroke of each mounting part is consistent and the lateral spacing between two adjacent mounting parts does not change.

[0024] Furthermore, the rotation driving unit includes a gear fixedly sleeved on one end of the rotating shaft passing through the fixed seat, and a plurality of first rack portions are arranged in an array on the inner hole wall of the fixed seat along the axis of the roller shaft, and the position and number of the first rack portions are adapted to the position and number of the tooth blocks on the mounting portion, a flange seat is fixedly connected to the inner side wall of the frame, a fixed plate is coaxially fixedly connected to the end of the flange seat, a plurality of second rack portions are arranged on the periphery of the fixed plate, the second rack portions are arranged corresponding to the first rack portions, and a gear section is arranged on the periphery of the rotating shaft, and the gear and the first rack portion can intermittently mesh internally when the roller shaft rotates, and the gear section can mesh externally with the second rack portion when the gear and the first rack portion are disengaged.

[0025] Through the above technical solution, when the rotating seat rotates, the gear will intermittently mesh with the inside of the first rack portion, so that the gear drives the rotating shaft to rotate in one direction, thereby increasing the distance between two adjacent mounting portions. When the gear is disengaged from the first rack portion, the gear segment will mesh with the outside of the second rack portion, thereby causing the rotating shaft to rotate in the opposite direction, thereby restoring the distance between two adjacent mounting portions to its original state.

[0026] The beneficial effects of the present invention are as follows: (1) In the present invention, when the material is stuck, the driving mechanism drives the roller to rotate slightly in the opposite direction, so that the solid waste exerts pressure on the movable block. Under the pressure, the movable mechanism drives the movable block to move horizontally, thereby driving the solid waste to move horizontally slightly, thereby adjusting the position of the solid waste on the mounting portion so that the tooth block can bite the solid waste. In addition, if the tooth block still gets stuck, the above steps can be repeated automatically until the tooth block can bite the solid waste and crush the solid waste. (2) In the present invention, after the tooth block cuts the longer solid waste, the length or width of the cut solid waste may be greater than the lateral spacing between two adjacent mounting parts on the same roller shaft, which may cause the cut solid waste to be stuck between the two adjacent mounting parts on the same roller shaft, resulting in the inability to fall smoothly. Therefore, through the spacing self-adjusting mechanism, after the tooth block cuts and crushes the solid waste, the spacing between the two adjacent mounting parts on the same roller shaft is increased, so that the cut solid waste can fall smoothly from between the two adjacent mounting parts; (3) In the present invention, when the roller shaft rotates, it will synchronously drive the two rotating seats on both sides of its axis to rotate. When the rotating seats rotate, the two rotating shafts will rotate around the axis of the roller shaft. During rotation, the rotating drive unit will intermittently drive the rotating shaft to rotate, so that the nut sleeve and the external thread sleeve are threaded together, and then the nut sleeve drives the mounting part to produce horizontal movement. In addition, since the thread pitch of the external thread sleeve decreases successively, the movement stroke of each mounting part is changed successively, so that the spacing between the multiple mounting parts on the roller shaft can be increased, avoiding the phenomenon that the movement stroke of each mounting part is consistent and the lateral spacing between two adjacent mounting parts does not change.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0030] like Figure 1-Figure 12As shown, this embodiment provides a solid waste treatment device, including a frame 7, on which two rollers are connected to rotate horizontally by installing a bearing seat, and the two rollers are symmetrically distributed along the center line of the frame 7. A reduction box 2 is installed on the outer side of the frame 7, and the input end of the reduction box 2 is drivingly connected to a motor 1 placed on a placement surface. When the motor shaft of the motor 1 rotates, it will drive the reduction box 2 to rotate. One end of one of the rollers is drivingly connected to the output end of the reduction box 2, so that when the reduction box 2 rotates, it will drive the roller to rotate. A gear transmission unit 6 is installed on the side of the frame 7 away from the reduction box 2. The gear transmission unit 6 includes two transmission gears. Two transmission gears are respectively fixedly sleeved on the ends of the two rollers, and the two transmission gears are meshed, so that when the reduction box 2 drives one roller to rotate, the two transmission gears in the gear transmission unit 6 are meshed and transmitted, and then the other roller can be driven to rotate synchronously in the opposite direction. An electric control cabinet 8 is provided on the frame 7, and a torque sensor is installed on one of the rollers. The motor 1 and the torque sensor (not shown in the figure) are both electrically connected to the electric control cabinet 8. A feeding port 4 is installed on the top of the frame 7, through which the solid waste to be crushed can be put into the frame 7, and the solid waste falls between the two rollers. In addition, a discharge port 9 is formed on the lower side of the frame 7; The periphery of the roller shaft is provided with mounting parts 5 at a fixed interval, the mounting parts 5 are coaxial with the roller shaft, and the mounting parts 5 are key-connected with the roller shaft, so that the mounting parts 5 can slide on the periphery of the roller shaft along the axial direction of the roller shaft, and the mounting parts 5 on the two roller shafts are arranged alternately, that is, the mounting parts 5 on one roller shaft are engaged between two adjacent mounting parts 5 on the other roller shaft, and the periphery of the mounting parts 5 is provided with a plurality of assembly openings in an array along its axial direction, the assembly openings are in the form of notches, and tooth blocks 3 are welded in the assembly openings, and the tooth blocks 3 are provided with an arc-shaped opening on one side for biting the material and crushing it, and a recessed receiving groove 22 is provided on the non-working surface (that is, the side that does not participate in biting the material and crushing it), and a movable block 16 is engaged and installed in the receiving groove 22, and the movable block 16 slides freely in the receiving groove 22, and specifically, the movable block 16 can be both water-locked and moved in the receiving groove 22. The movable block 16 is provided with a waist-shaped hole 27 for the sliding pin 25 to be inserted into the surface of the movable block 16, and the length direction of the waist-shaped hole 27 is at an angle to the axial direction of the support shaft 23. The two ends of the support shaft 23 are respectively wrapped with a return spring 24, and the two ends of the return spring 24 in the elastic force direction elastically press against the outer wall of the movable block 16 and the inner wall of the accommodating groove 22. In the initial state, the two return springs 24 generate elastic pressing forces of equal size and opposite direction on the movable block 16, thereby causing the movable block 16 to move in the radial outer direction of the mounting portion 5 in the accommodating groove 22 until the sliding pin 25 is engaged with the lower side of the waist-shaped hole 27 in the length direction (reference Fig.12 ), and at this time, the movable block 16 protrudes to the non-working surface of the tooth block 3, and a plurality of stripe grooves are provided on one side of the movable block 16 exposed from the tooth block 3. Furthermore, the length direction of the stripe grooves is perpendicular to the axial direction of the mounting portion 5. The arrangement of the stripe grooves increases the friction between the surface of the movable block 16 and the surface of the solid waste; A fixing plate 10 is connected to the inner wall of one side of the frame 7 by screws or welded thereto. Two fixing seats 14 are fixedly connected to the inner wall of the side of the frame 7 away from the fixing plate 10. A rotating seat 11 is rotatably connected to each of the fixing seat 14 and the fixing plate 10. Specifically, two rotating seats 11 are provided on the fixing plate 10, and a rotating seat 11 is provided on the fixing seat 14. The two rotating seats 11 at the axial ends of the same roller shaft are rotatably connected to two rotating shafts 15 together through mounting bearings. Two nut sleeves 21 are embedded on the end surface of the mounting portion 5. An external thread sleeve 17 is fixedly sleeved on the periphery of the rotating shaft 15. The external thread sleeve 17 is correspondingly threadedly inserted into the nut sleeve 21. The thread pitches of the multiple external thread sleeves 17 on the same rotating shaft 15 decrease in sequence in the direction away from the fixing seat 14. The rotating shaft 15 penetrates into the fixing seat 14. A gear 12 is fixedly sleeved on the inner end, and a plurality of first rack portions 20 are arranged in an array on the inner hole wall of the fixed seat 14 along the axis of the roller shaft. The position and number of the first rack portions 20 are adapted to the position and number of the tooth blocks 3 on the mounting portion 5. A flange seat 13 is fixedly connected to the inner side wall of the frame 7, and a fixed plate 18 is coaxially fixedly connected to the end of the flange seat 13. A plurality of second rack portions 19 are arranged on the periphery of the fixed plate 18, and the second rack portions 19 are arranged corresponding to the first rack portions 20. A gear segment 28 is opened on the periphery of the rotating shaft 15. The gear 12 and the first rack portion 20 can be intermittently meshed internally when the roller shaft rotates. The gear segment 28 can be externally meshed with the second rack portion 19 when the gear 12 and the first rack portion 20 are disengaged, and the number of the second rack portions 19 is consistent with the number of tooth blocks 3 on the same mounting portion 5.

[0031] The working principle of this embodiment is as follows: The solid waste to be crushed is put between the two rollers, and the motor 1 is started. The motor shaft of the motor 1 drives the reduction box 2 to rotate. When the reduction box 2 rotates, it will drive one of the rollers to rotate. When the roller rotates, it will drive the other roller to rotate through the gear transmission unit 6, so that the two rollers rotate synchronously in opposite directions, and then the gear blocks 3 on the two rollers generate a biting force on the solid waste, so that the solid waste is bitten between the two rollers, and the working surface of the gear block 3 bites and crushes the solid waste; When the solid waste is bitten by the tooth blocks 3 on the two rollers, the solid waste's own gravity and the longitudinal component of the squeezing force of the tooth blocks 3 on the solid waste act together on the movable block 16, so that the movable block 16 is subjected to a force in the direction of being retracted into the inner side of the accommodating groove 22, thereby causing the sliding pin 25 to slide in the waist-shaped hole 27, so that the sliding pin 25 slides from the lower side of the waist-shaped hole 27 in the length direction to the upper side of the waist-shaped hole 27 in the length direction, thereby causing the movable block 16 to move horizontally, and one of the return springs 24 is squeezed by the movable block 16 to accumulate elastic potential energy. In addition, since the solid waste is bitten by the tooth blocks 3 at this time, the solid waste will not move horizontally. When the size of the part of the solid waste bitten by the tooth blocks 3 is large, the tooth blocks 3 may not be able to crush the solid waste, thereby causing the material to jam. At this time, the torque parameter collected by the torque sensor is large, and the torque sensor feeds back the torque signal to the electric control cabinet 8, and the electric control cabinet 8 controls the electric The machine 1 rotates in the reverse direction slightly, causing the roller shaft to rotate in the reverse direction slightly. The roller shaft will rotate in the opposite direction of the original rotation direction, causing the movable block 16 to rotate in the reverse direction. At this time, the gripping force of the tooth block 3 on the solid waste is reduced. At the same time, since the solid waste moves upward on the periphery of the mounting portion 5, the elastic potential energy of the reset spring 24 is released, causing the movable block 16 to move in the reverse direction. The sliding pin 25 will slide from the upper side to the lower side in the length direction of the waist-shaped hole 27, so that the movable blocks 16 on the multiple tooth blocks 3 can lift the solid waste together. Since the movable blocks 16 move horizontally at the same time, the solid waste can be driven to move horizontally, so that the position of the solid waste on the tooth block 3 can be changed. Then the motor 1 rotates forward again, causing the tooth block 3 to re-engage the solid waste and crush the solid waste. If the tooth block 3 still has material stuck, the above steps can be repeated automatically until the tooth block 3 can bite the solid waste and crush the solid waste. In addition, when the roller is rotating, it will synchronously drive the two rotating seats 11 on both sides of its axis to rotate. When the rotating seat 11 rotates, the two rotating shafts 15 will rotate around the axis of the roller. During rotation, the gear 12 will begin to engage with the first rack portion 20 internally, causing the rotating shaft 15 to rotate. When the rotating shaft 15 rotates, the nut sleeve 21 and the external thread sleeve 17 will be threaded together, thereby causing the nut sleeve 21 to drive the mounting portion 5 to move horizontally. In addition, since the thread pitch of the external thread sleeve 17 decreases successively, the movement stroke of each mounting portion 5 changes successively, thereby increasing the spacing between the multiple mounting portions 5 on the roller. In this way, during the process of crushing solid waste, the spacing between the two corresponding tooth blocks 3 on the two rollers is greater than the width of the tooth block 3 on the same roller (refer to Fig.10, the width direction of the tooth block 3 is consistent with the length direction of the accommodating groove 22), so that the solid waste cut by the tooth block 3 will not be stuck between the two adjacent mounting parts 5, so that the cut solid waste can fall smoothly. After cutting and crushing, as the roller continues to rotate, the gear 12 begins to disengage from the first rack part 20, and then the gear segment 28 begins to engage with the second rack part 19 externally, so that the rotating shaft 15 starts to rotate in the opposite direction, and then the mounting part 5 starts to move in the opposite direction until it returns to the original spacing size. In addition, in this embodiment, the lateral spacing size of the two adjacent mounting parts 5 in the original state is set to be slightly larger than the width size of the tooth block 3. In this way, when the material is stuck, when the roller rotates in the opposite direction of the original rotation direction, the lateral spacing of the two adjacent mounting parts 5 ensures that when the roller rotates in the opposite direction, the opposite surfaces of the two adjacent mounting parts 5 will not produce a large extrusion with the surface of the mounting part 5 stuck between the two adjacent mounting parts 5; It should also be noted that the width of the tooth block 3 cannot be greater than the thickness of the mounting portion 5, so as to avoid the portion of the tooth block 3 protruding from the mounting portion 5 being damaged by a large squeezing force when cutting and crushing solid waste.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention.
