The treatment of coal gangue solid waste involves a series of operations such as crushing, screening, and separation to extract useful components from it, achieve resource recovery and utilization, reduce environmental pollution. For example, extracting mineral resources such as coal and kaolin from it, which can be used in fields such as building materials and chemical raw materials. It can also reduce the land occupation caused by its accumulation through treatment and mitigate the damage to the surrounding ecological environment.

[0003] In the prior art, there are many deficiencies in the treatment of coal gangue solid waste. On the one hand, the efficiency of the crushing link is relatively low. Common treatment devices rely only on a single crushing structure and are difficult to fully crush coal gangue, which has a high hardness and complex composition, resulting in increased difficulty in subsequent treatment and low resource recovery rate. On the other hand, the screening effect is not ideal, and the screening structure is prone to clogging, causing some coal gangue to accumulate inside, affecting the overall treatment progress. In addition, the overall integration of the equipment is not high, each treatment link is relatively independent, lacking an efficient collaborative operation mechanism, resulting in waste of space and large energy consumption.

Detailed implementation manners

[0020] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with the specific implementation manners.

[0021] Embodiment 1

[0022] As Figures 1 to 10As shown in the figure, a coal gangue solid waste treatment device according to an embodiment of the present invention includes a box body 1; receiving rings 11 are fixedly connected to both side walls of the box body 1, a receiving frame 12 is fixedly connected to the bottom of the receiving ring 11, and the receiving frame 12 penetrates the box body 1; arc-shaped filter rings 13 are rotatably connected to the ends of a pair of the receiving rings 11, and circular filter rings 14 are fixedly connected to the ends of a pair of the arc-shaped filter rings 13; a rotating ring 15 and a fixed ring 16 are respectively rotatably connected to the opposite ends of a pair of the circular filter rings 14, a rotating toothed ring 17 is rotatably connected to the inner wall of the fixed ring 16, a convex ring disc 18 is provided on the inner wall of the rotating toothed ring 17, a groove is formed at the end of the rotating ring 15, and crushing grooves 19 are formed at the opposite ends of the groove and the convex ring disc 18; a feed pipe 111 is fixedly connected to the fixed ring 16 through a feed slot, and the feed pipe 111 penetrates the top of the box body 1; a collection box is provided at the bottom of the box body 1; a group of sliding blocks 112 are fixedly connected to the inner wall of the rotating toothed ring 17, a group of sliding grooves 113 are formed on the outer wall of the convex ring disc 18, and the sliding blocks 112 are slidably connected in the sliding grooves 113; a receiving and pressing member is provided between the convex ring disc 18 and the rotating ring 15; a power assembly is provided in the box body 1, and the reverse rotation of the rotating ring 15 and the convex ring disc 18 and the operation of the receiving and pressing member are all driven by the power assembly; during operation, coal gangue enters the fixed ring 16 through the feed pipe 111 via the feed slot, the rotating ring 15 and the convex ring disc 18 rotate in opposite directions driven by the power assembly, the coal gangue is initially crushed by the crushing grooves 19, and then enters the circular filter rings 14 on both sides to rotate at a high speed and is screened under the action of centrifugal force. The smaller and compliant coal gangue is collected through the filter rings, and part of the coal gangue enters the arc-shaped filter rings 13 and then enters the receiving frame; the rotating toothed ring 17 and the convex ring disc 18 are matched by the sliding blocks 112 and the sliding grooves 113, and can maintain relative stability during rotation, and at the same time provide a basis for the subsequent operation of the receiving and pressing member, so that the crushing of the coal gangue is not only through the crushing of the crushing grooves 19, but also through the extrusion and crushing of the convex ring disc 18 and the fixed ring 16, improving the crushing efficiency, and the extrusion of the convex ring disc 18 is also beneficial to the crushed coal gangue entering the circular filter rings 14 on both sides, improving the screening effect.

[0023] Further, filter meshes are fixedly connected to the middle grooves of the rotating ring 15 and the convex ring disc 18; through the establishment of the filter meshes, the compliant small coal gangue blocks after crushing can enter the circular filter rings 14 for screening, and the large coal gangue blocks continue to be crushed in the crushing grooves 19.

[0024] The receiving and squeezing member includes a spherical ball 2. One end of the convex ring plate 18 is spherically connected with a group of spherical balls 2 through an extension column. A pair of reciprocating lead screws 21 are rotatably connected between the opposite side walls of the box body 1, and the pair of reciprocating lead screws 21 are fixedly connected. A twisted push plate 22 is fixedly connected to the reciprocating lead screw 21, and the twisted push plate 22 is in contact with the spherical ball 2. One end of the convex ring plate 18 is rotatably connected with a connecting ring 23. An arc-shaped plate 24 is slidably connected to the lower proximal part of the central groove of the rotating ring 15 through a square groove, and the arc-shaped plate 24 is in contact with the convex ring plate 18. The bottom of the arc-shaped plate 24 is fixedly connected to the connecting ring 23 through a connecting column 25. During operation, the power assembly drives the reciprocating lead screw 21 to rotate. The twisted push plate 22 on the reciprocating lead screw 21 pushes the spherical ball 2, and the spherical ball 2 drives the convex ring plate 18 to move axially back and forth along the reciprocating lead screw 21. Due to the special twisted structure of the twisted push plate 22 and the differential rotation between the convex ring plate 18 and the twisted push plate 22, the twisted push plate 22 can drive the convex ring plate 18 to displace cyclically through the spherical ball 2. And because of the squeezing force of the coal gangue between the convex ring plate 18 and the rotating ring 15, the spherical ball 2 is always in contact with the twisted push plate 22. The sliding block 112 and the sliding groove 113 provide guidance for the movement of the convex ring plate 18. When the convex ring plate 18 moves back and forth, it drives the arc-shaped plate 24 to slide in the square groove of the rotating ring 15 through the connecting ring 23 and the connecting column 25. At the same time, the rotating ring 15 drives the arc-shaped plate 24 to rotate slowly, turning the coal gangue on the arc-shaped plate 24 into the crushing groove 19 located below the rotating ring 15, so that the crushing groove 19 below also participates in the crushing work. When the arc-shaped plate 24 is flipped again, the crushed coal gangue is conveyed into a pair of circular filter rings 14. With this design, through the flipping of the arc-shaped plate 24, the coal gangue on the arc-shaped plate 24 has kinetic energy as it flips. When it rolls and slides on the arc-shaped plate 24, the coal gangue above it efficiently enters the pair of circular filter rings 14.

[0025] Further, an arc-shaped groove is formed in the arc-shaped plate 24. A contact plate is fixedly connected to the inner wall of the arc-shaped groove through a group of springs, and the contact plate is in contact with the groove. The bottom of the arc-shaped plate 24 is fixedly connected to the fixed ring 16 through a fixed rod. With this design, the arc-shaped plate 24 does not flip during operation. The contact plate contacts the groove through the side wall springs, making it have elasticity, avoiding the coal gangue on the arc-shaped plate 24 from entering its bottom, resulting in difficulty for some coal gangue to enter the circular filter rings 14 again after reaching the bottom of the groove.

[0026] The power assembly includes a transmission unit, a driving unit, and a first shaft 3; a first shaft 3 and a second shaft 31 are rotatably connected between opposite side walls of the box body 1, a motor 32 is fixedly connected to the end of the first shaft 3, and the motor 32 is fixedly connected to the side wall of the box body 1; a pair of power gears 33 and transmission gears 34 are respectively fixedly connected to the first shaft 3 and the second shaft 31, and the transmission gear 34 meshes with the power gear 33; a fixed tooth ring 35 is fixedly connected to each of the pair of circular filter rings 14, and the fixed tooth ring 35 meshes with the transmission gear 34; during operation, after the motor 32 is started, it drives the first shaft 3 to rotate, the power gear 33 on the first shaft 3 meshes with the transmission gear 34 on the second shaft 31, transmits the power to the second shaft 31, and then drives the circular filter ring 14 to rotate, so as to enable the arc-shaped filter ring 13 and the circular filter ring 14 to screen the coal gangue; at the same time, the rotation of the first shaft 3 provides a power source for the subsequent transmission unit and driving unit.

[0027] Further, the diameter of the power gear 33 is larger than that of the transmission gear 34; during operation, this design can make the subsequent power structure driven by the first shaft 3, as well as the rotation speeds of the fixed ring 16 and the convex ring disc 18 relatively slow, while the rotation speeds of the circular filter ring 14 and the arc-shaped filter ring 13 are relatively fast, and then screen the coal gangue through centrifugal force.

[0028] The transmission unit includes a support block 4; a support block 4 is fixedly connected to the bottom of the box body 1, a third shaft 41 and a fourth shaft 42 are respectively rotatably connected to the side wall of the support block 4 and the side wall of the box body 1, first bevel gears 43 are fixedly connected to the ends of the third shaft 41 and the fourth shaft 42, and a sixth shaft 44 is rotatably connected to the side wall of the box body 1; a second bevel gear 45 and a first worm gear 47 are fixedly connected to the sixth shaft 44, and the second bevel gear 45 meshes with a pair of first bevel gears 43; a worm groove 46 is provided on the first shaft 3, and the first worm gear 47 meshes with the worm groove 46; during operation, the worm groove 46 on the first shaft 3 meshes with the first worm gear 47 on the sixth shaft 44, transmits the rotation of the first shaft 3 to the sixth shaft 44; the second bevel gear 45 on the sixth shaft 44 meshes with the first bevel gears 43 on the third shaft 41 and the fourth shaft 42, transmits the power to the third shaft 41 and the fourth shaft 42 respectively, and realizes the branched transmission of power; the rotating ring 15 and the convex ring disc 18 are driven to rotate in opposite directions through the third shaft 41 and the fourth shaft 42, so as to achieve the effect of crushing the coal gangue.

[0029] The driving unit includes a tooth groove 7. A tooth groove 7 is formed on the outer wall of the outer ring of the rotating ring 15. A through groove is formed on the fixed ring 16. Driving gears 71 are fixedly connected to both the third shaft 41 and the fourth shaft 42. A pair of driving gears 71 are respectively meshed with the tooth groove 7 and the rotating tooth ring 17. During operation, the driving gears 71 on the third shaft 41 and the fourth shaft 42 are respectively meshed with the tooth groove 7 on the rotating ring 15 and the rotating tooth ring 17, transmitting the rotation of the third shaft 41 and the fourth shaft 42 to the rotating ring 15 and the rotating tooth ring 17, realizing the reverse rotation of the rotating ring 15 and the convex ring plate 18, and ensuring the crushing effect of the crushing groove 19 on the coal gangue.

[0030] The cross-sections of the central grooves of the convex ring plate 18 and the rotating ring 15 are trumpet-shaped, and the smaller ends of a pair of trumpet-shaped openings are correspondingly arranged. During operation, the trumpet-shaped structures of the central grooves of the convex ring plate 18 and the rotating ring 15 play a dispersing role when the coal gangue enters the grooves, enabling the coal gangue to enter the circular filter ring 14 more dispersedly and improving the screening effect.

[0031] Embodiment 2

[0032] As Figures 1 to 10 shown, circular half-rings 5 are fixedly connected to both side walls of the box body 1, and the reciprocating lead screw 21 is located inside the circular half-rings 5. A pair of rotation-limiting rings 51 are fixedly connected to the reciprocating lead screw 21. The rotation-limiting rings 51 extend out of the circular half-rings 5 and are fixedly connected to a material guiding plate 52, and the material guiding plate 52 is arranged in a twisted shape. The inner wall of the arc-shaped filter ring 13 is fixedly connected to the circular half-ring 5 through a group of fixing rods. A receiving block is fixedly connected to the bottom of the box body 1, and the receiving block is fixedly connected to the fixed ring 16 and is rotatably connected to the rotating ring 15. A fifth shaft 53 is rotatably connected to the side wall of the box body 1, and the fifth shaft 53 penetrates through the fixed ring 16 and is fixedly connected to a third bevel gear 54. A fourth bevel gear 55 is fixedly connected to the reciprocating lead screw 21, and the third bevel gear 54 and the fourth bevel gear 55 are meshed. A second worm 56 is fixedly connected to the fifth shaft 53, and the second worm 56 is meshed with the turbine groove. During operation, when the reciprocating lead screw 21 rotates, since the groove on the fixed half-ring restricts the rotation of the rotation-limiting ring 51, the rotation-limiting ring 51 drives the material guiding plate 52 to reciprocate. The twisted shape of the material guiding plate 52 can guide the coal gangue to move inside the circular half-ring 5, thereby driving the coal gangue inside the circular filter ring 14 into the arc-shaped filter ring 13 and then being collected. The third bevel gear 54 on the fifth shaft 53 is meshed with the fourth bevel gear 55 on the reciprocating lead screw 21, causing the fifth shaft 53 to drive the reciprocating lead screw 21 to rotate, driving the material guiding plate 52 to guide the coal gangue into the arc-shaped filter ring 13 through the reciprocating lead screw 21, and driving the twisted pushing plate 22 to rotate, realizing the extrusion of the convex ring plate 18 by the ball 2 and completing the extrusion and crushing of the coal gangue.

[0033] Further, a water pump and a water tank are fixedly connected to the top of the box body 1. A group of water spraying grooves are arranged inside the circular semi-ring 5. The outlet end of the water pump is communicated with the inside of the circular semi-ring 5 through a water outlet pipe. A water filtering groove is arranged at the bottom of the box body 1. During operation, with this design, the coal gangue can be washed during centrifugal separation, and the washing of the coal gangue is completed.

[0034] A group of twisted material guiding plates 6 are fixedly connected to the inner ring wall of a pair of the arc-shaped filter rings 13. A group of material guiding blocks 61 are fixedly connected to the inner ring wall of the circular filter ring 14, and the material guiding blocks 61 are distributed in a spiral shape. The cross section of the material guiding block 61 is similar to a triangle, and the inclined surface of the triangle is inclined towards the arc-shaped filter ring 13 and has the same rotation direction as the circular filter ring 14. During operation, the twisted material guiding plates 6 on the arc-shaped filter ring 13 guide the coal gangue to move inside the arc-shaped filter ring 13 during rotation, increasing the contact area between the coal gangue and the filter ring, improving the screening effect, and guiding the coal gangue into the receiving frame 12 for collection. The spiral-distributed material guiding blocks 61 on the circular filter ring 14 push the coal gangue to move along the spiral direction when the circular filter ring 14 rotates, making the coal gangue evenly distributed inside the filter ring. At the same time, by using the inclined surface of the similar triangle of the material guiding block 61, the coal gangue is guided into the arc-shaped filter ring 13, and through the inclined surface design of the material guiding block 61, some coal gangue is separated from the circular filter ring 14 during the centrifugal motion along its inclined surface, increasing the effect of mutual collision and fragmentation of the coal gangue.

[0035] Working principle: The coal gangue enters into the fixed ring 16 through the feed pipe 111 via the feed trough. The rotating ring 15 and the convex ring plate 18 rotate in opposite directions driven by the power assembly. The coal gangue is preliminarily crushed by the crushing trough 19, and then enters the circular filter rings 14 on both sides to rotate at high speed. It is sieved under the action of centrifugal force. The smaller and compliant coal gangue is collected through the filter rings. Part of the coal gangue enters the arc-shaped filter ring 13 and then enters the receiving frame. The rotating gear ring 17 and the convex ring plate 18 are matched through the sliding block 112 and the sliding groove 113, and can maintain relative stability during rotation. At the same time, it provides a basis for the operation of the subsequent receiving and squeezing parts, so that the crushing of the coal gangue is not only through the crushing of the crushing trough 19, but also through the extrusion and crushing of the convex ring plate 18 and the fixed ring 16, improving the crushing efficiency. Moreover, the extrusion of the convex ring plate 18 is also conducive to the crushed coal gangue entering the circular filter rings 14 on both sides, improving the sieving effect. The power assembly drives the reciprocating lead screw 21 to rotate. The twisted push plate 22 on the reciprocating lead screw 21 pushes the ball 2, and the ball 2 drives the convex ring plate 18 to move axially back and forth along the reciprocating lead screw 21. Because of the special twisted structure of the twisted push plate 22 and the differential rotation of the convex ring plate 18 and the twisted push plate 22, the twisted push plate 22 can drive the convex ring plate 18 to displace cyclically through the ball 2. And because of the extrusion force of the coal gangue between the convex ring plate 18 and the rotating ring 15, therefore, the ball 2 is always in contact with the twisted push plate 22. The sliding block 112 and the sliding groove 113 provide guidance for the movement of the convex ring plate 18. When the convex ring plate 18 moves back and forth, it drives the arc-shaped plate 24 to slide in the square groove of the rotating ring 15 through the connecting ring 23 and the connecting column 25. At the same time, the rotating ring 15 drives the arc-shaped plate 24 to rotate slowly, turning the coal gangue on the arc-shaped plate 24 into the crushing trough 19 located below the rotating ring 15, so that the crushing trough 19 located below also participates in the crushing work. When the arc-shaped plate 24 is turned over again, the crushed coal gangue is conveyed into a pair of circular filter rings 14. This design, through the turning of the arc-shaped plate 24, makes the coal gangue on the arc-shaped plate 24 have kinetic energy as it turns. When it rolls and slides on the arc-shaped plate 24, the coal gangue above it efficiently enters a pair of circular filter rings 14. After the motor 32 is started, it drives the first shaft 3 to rotate. The driving gear 33 on the first shaft 3 meshes with the transmission gear 34 on the second shaft 31, transmitting the power to the second shaft 31, and then driving the circular filter ring 14 to rotate, so that the arc-shaped filter ring 13 and the circular filter ring 14 screen the coal gangue. At the same time, the rotation of the first shaft 3 provides a power source for the subsequent transmission unit and the driving unit. The worm groove 46 on the first shaft 3 meshes with the first worm gear 47 on the sixth shaft 44, transmitting the rotation of the first shaft 3 to the sixth shaft 44. The second bevel gear 45 on the sixth shaft 44 meshes with the first bevel gears 43 on the third shaft 41 and the fourth shaft 42, transmitting the power to the third shaft 41 and the fourth shaft 42 respectively, realizing the branched transmission of power;Drive the rotating ring 15 and the convex ring disc 18 to rotate in opposite directions through the third shaft 41 and the fourth shaft 42 to achieve the effect of crushing coal gangue. When the reciprocating lead screw 21 rotates, since the groove on the fixed half-ring restricts the rotation of the rotation-limiting ring 51, the rotation-limiting ring 51 drives the material guiding plate 52 to move reciprocally. The twisted shape of the material guiding plate 52 can guide the coal gangue to move within the circular half-ring 5, and then drive the coal gangue within the circular filter ring 14 into the arc-shaped filter ring 13 and be collected. The third bevel gear 54 on the fifth shaft 53 meshes with the fourth bevel gear 55 on the reciprocating lead screw 21, causing the fifth shaft 53 to drive the reciprocating lead screw 21 to rotate, so that the reciprocating lead screw 21 drives the material guiding plate 52 to guide the coal gangue into the arc-shaped filter ring 13, and drives the twisted push plate 22 to rotate, realizing the extrusion of the convex ring disc 18 by the spherical ball 2 to complete the extrusion and crushing of the coal gangue. During the rotation of the twisted material guiding plate 6 on the arc-shaped filter ring 13, it guides the coal gangue to move within the arc-shaped filter ring 13, increasing the contact area between the coal gangue and the filter ring, improving the screening effect, and guiding the coal gangue into the receiving frame 12 for collection. The material guiding blocks 61 distributed in a spiral on the circular filter ring 14 push the coal gangue to move along the spiral direction when the circular filter ring 14 rotates, making the coal gangue evenly distributed within the filter ring. At the same time, using the triangular-like inclined surface of the material guiding blocks 61 to guide the coal gangue into the arc-shaped filter ring 13, and through the inclined surface design of the material guiding blocks 61, part of the coal gangue is separated from the centrifugal motion in contact with the circular filter ring 14 along its inclined surface, increasing the collision and crushing effect of the coal gangue. The driving gears 71 on the third shaft 41 and the fourth shaft 42 mesh with the tooth grooves 7 and the rotating tooth ring 17 on the rotating ring 15 respectively, transmitting the rotation of the third shaft 41 and the fourth shaft 42 to the rotating ring 15 and the rotating tooth ring 17, realizing the reverse rotation of the rotating ring 15 and the convex ring disc 18, ensuring the crushing effect of the crushing groove 19 on the coal gangue. The horn-shaped structure of the central grooves of the convex ring disc 18 and the rotating ring 15 plays a dispersing role when the coal gangue enters the groove, making the coal gangue enter the circular filter ring 14 more dispersedly and improving the screening effect.
