Description

Technical Field

[0001] This utility model relates to the field of coal-based solid waste processing technology, specifically to a coal-based solid waste crushing and mixing device. Background Technology

[0002] Coal-based solid waste, as the main solid waste generated in the coal industry chain, requires crushing and mixing as the core link to achieve resource utilization. Crushing can reduce particle size, increase specific surface area, and improve reaction activity and mixing uniformity. Mixing optimizes material performance through multi-component synergy, laying the foundation for high-value utilization. For example, after crushing coal gangue, it can be mixed with gasification slag, fly ash, etc. to prepare paste filling materials, low-carbon cementitious materials, etc., which can not only solve the problem of stockpiling pollution, but also create economic value.

[0003] However, existing coal-based solid waste mixing equipment mostly involves directly pouring mixed fragments of coal gangue, fly ash, desulfurization gypsum, gasification slag, and bottom ash into the equipment for crushing and mixing. This makes it inconvenient to crush the fragments of coal gangue, fly ash, gasification slag, and bottom ash separately. Furthermore, the mixture is usually stirred in one direction, which may cause the mixture to move along with the stirring rod, thus reducing the mixing effect. Utility Model Content

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0027] Example 1:

[0028] like Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a coal-based solid waste crushing and mixing device, including a crushing box 1, four feeding hoppers 2 fixed on the side of the crushing box 1, a crushing motor 3 fixed on the top cover of the crushing box 1, an inner frame 4 fixed inside the crushing box 1, a crushing structure 5 provided between the inner frame 4 and the crushing box 1, a mixing box 6 fixed at the bottom of the crushing box 1, a discharge pipe 7 fixed on the side of the mixing box 6, a base 8 fixed at the bottom of the mixing box 6, and a mixing structure 9 provided inside the mixing box 6.

[0029] The crushing structure 5 includes a crushing chamber 51, which is formed by the gap between the inclined partition inside the crushing box 1, the crushing box 1, and the inner frame 4. A long shaft 52 rotates between the crushing box 1 and the inner frame 4. A crushing roller 53 is fixed on the long shaft 52. A crushing shaft 54 ​​is fixed at the output end of the crushing motor 3. A drive bevel gear 55 is fixed at the bottom of the crushing shaft 54. An L-shaped bracket 56 is fixed on the side of the inner frame 4. A toothed ring 57 rotates on the L-shaped bracket 56 via a pivot pin. A driven bevel gear 58 is fixed on the toothed ring 57. The surface of the long shaft 52 is located within the inner frame. The internal part of the 4 is fixed with a crushing toothed ring 59 and a second toothed ring 510. Through the feed hopper 2, coal gangue, fly ash, gasification slag and bottom ash can be poured into the crushing chambers 51 at different positions. Starting the crushing motor 3 can cause the crushing shaft 54 ​​to drive the drive bevel tooth 55 to rotate. Through the meshing of the drive bevel tooth 55 with the driven bevel tooth 58, the meshing of the first toothed ring 57 with the second toothed ring 510 and the meshing of the two crushing toothed rings 59, the two crushing rollers 53 can rotate in opposite directions, so that coal gangue, fly ash, gasification slag and bottom ash can be crushed and processed separately.

[0030] Furthermore, four crushing chambers 51 are provided. The upper part of the crushing chamber 51 is a square pyramid shape, and the lower part is rectangular, which facilitates the pouring of coal gangue, fly ash, gasification slag and bottom ash into the crushing chambers 51 at different positions. This allows for the individual crushing of coal gangue, fly ash, gasification slag and bottom ash. The crushing chamber 51 is connected to the rotating drum 94, and the crushed waste material can fall into the rotating drum 94. The crushing chamber 51 is provided with a triangular ramp inside so that the waste material can fall between the two crushing rollers 53.

[0031] Furthermore, the crushing rollers 53 are provided in four sets, with two rollers in each set. The two crushing rollers 53 are located inside the crushing chamber 51, which facilitates the individual crushing of coal gangue, fly ash, gasification slag, and bottom ash through the synchronous reverse rotation of the two crushing rollers 53. The crushing rollers 53 are cylindrical in shape, and extrusion ridges are fixed on the surface of the crushing rollers 53 along their length. Multiple extrusion ridges are distributed around the circumference of the crushing rollers 53. When the two crushing rollers 53 rotate in opposite directions, the extrusion ridges on the two crushing rollers 53 move alternately and do not contact each other. After the waste fragments fall between the two crushing rollers 53, the gap between the two reverse-rotating crushing rollers 53 will exert an extrusion effect on the waste fragments, thereby achieving material crushing and improving the crushing efficiency of coal-based solid waste.

[0032] Furthermore, the driving bevel tooth 55 meshes with the driven bevel tooth 58, the first gear ring 57 meshes with the second gear ring 510, and the crushing gear rings 59 on the two long shafts 52 mesh with each other. The L-shaped bracket 56 can support the rotation of the first gear ring 57 and the driven bevel tooth 58. The driving bevel tooth 55 can drive the driven bevel tooth 58 to rotate, the driven bevel tooth 58 can drive the first gear ring 57 to rotate, the first gear ring 57 can drive the second gear ring 510 to rotate, and the second gear ring 510 can drive one of the crushing gear rings 59 to rotate, thereby enabling the two crushing gear rings 59 to rotate in opposite directions.

[0033] Example 2:

[0034] like Figure 1 , Figure 5 and Figure 6 As shown, based on Example 1, the mixing structure 9 can be used to uniformly mix and process the pulverized mixture.

[0035] Furthermore, the stirring structure 9 includes a stirring motor 91, which is fixed to the side of the stirring box 6 via a support plate. A stirring toothed ring 92 is fixed to the output end of the stirring motor 91. A bearing 93 rotates inside the cylindrical cavity of the stirring box 6. A rotating drum 94 rotates in the stirring box 6 via the bearing 93. A toothed groove 95 is provided on the outer surface of the rotating drum 94, and the stirring toothed ring 92 meshes with the toothed groove 95. An outer stirring rod 96 is fixed to the inner surface of the rotating drum 94. A stirring shaft 97 rotates on the base 8, and an inner stirring rod 98 is fixed on the stirring shaft 97. Crushed coal gangue, fly ash, gasification slag, and bottom ash waste fall into the rotating drum 94. The stirring shaft 97 can stir the waste to one side via the inner stirring rod 98, and the stirring motor 91 can drive the outer stirring rod 96 to rotate to the other side via the meshing of the stirring toothed ring 92 and the toothed groove 95, so that the outer stirring rod 96 can stir the waste to the other side, so as to uniformly mix the waste.

[0036] Furthermore, the top end of the stirring shaft 97 is fixedly connected to the drive bevel gear 55, so that the drive bevel gear 55 can drive the inner stirring rod 98 to rotate through the stirring shaft 97.

[0037] Furthermore, the outer stirring rod 96 and the inner stirring rod 98 are staggered in the vertical direction, that is, the outer stirring rod 96 is between the two inner stirring rods 98, to prevent the outer stirring rod 96 and the inner stirring rod 98 from interfering when they rotate in opposite directions.

[0038] Furthermore, the discharge pipe 7 is inclined, and an electric rod is fixed on the discharge pipe 7. The electric rod is equipped with a gate for opening and closing the internal channel of the discharge pipe 7. The inner bottom of the mixing tank 6 is inclined to the side of the discharge pipe 7. A gap is left between the bottom end of the rotating drum 94 and the inner bottom surface of the mixing tank 6. By leaving a gap between the bottom end of the rotating drum 94 and the inner bottom surface of the mixing tank 6, it is easy for the mixed waste to fall onto the inner bottom surface of the mixing tank 6. The inner bottom surface of the mixing tank 6 is inclined, so that the waste on the inner bottom surface of the mixing tank 6 can slide and accumulate towards the port of the discharge pipe 7. The electric rod can drive the gate to move upward and open the internal channel of the discharge pipe 7 so that the mixed waste can be discharged from the discharge pipe 7.

[0039] The working principle of this utility model is as follows: During use, coal gangue, fly ash, gasification slag, and bottom ash can be separately poured into the crushing chambers 51 at different positions through the feed hoppers 2 at different positions. At the same time, the crushing motor 3 is started, which drives the drive bevel gear 55 to rotate through the crushing shaft 54. The drive bevel gear 55, through meshing with the driven bevel gear 58, drives the first tooth ring 57 to rotate. The first tooth ring 57, through meshing with the second tooth ring 510, drives a long shaft 52 to rotate. The long shaft 52, through meshing with two crushing tooth rings 59, enables two crushing rollers 53 to rotate synchronously in opposite directions. Thus, the crushing rollers 53 inside the four crushing chambers 51 can crush different coal-based waste materials to improve the crushing effect. The crushed coal-based waste inside the four crushing chambers 51 is processed by the crushing rollers 53. Waste material falls into the rotating drum 94, and the driving bevel gear 55 drives the inner stirring rod 98 to rotate to one side via the stirring shaft 97. Thus, the inner stirring rod 98 can stir the crushed mixture to one side. At the same time, the stirring motor 91 is started to drive the stirring tooth ring 92 to rotate. The stirring tooth ring 92, through meshing with the tooth groove 95, can drive the rotating drum 94 to rotate to the other side. Then, the rotating drum 94 can stir the crushed mixture to the other side via the outer stirring rod 96. The stirring directions of the outer stirring rod 96 and the inner stirring rod 98 are opposite, so as to stir the mixture evenly and improve the stirring effect of the mixture. The stirred mixture settles on the base 8. After stirring is completed, the gate on the discharge pipe 7 is opened to discharge the stirred mixture.
