DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions 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.

[0026] In one embodiment, Figure 1-Figure 5 As shown, a solid waste sorting and recycling device for a power plant comprises a crushing box 1 and a sorting box 2 arranged at the lower end of the crushing box 1, wherein a crushing chamber 11 and a transport chamber 12 are sequentially arranged inside the crushing box 1 from top to bottom, a crushing structure 3 is arranged inside the crushing chamber 11, a crushing chamber 21 and a sorting chamber 22 are sequentially arranged inside the sorting box 2 from top to bottom, a filter plate 67 is arranged between the crushing chamber 21 and the sorting chamber 22, a sorting structure 7 is arranged inside the sorting chamber 22, a discharge port 23 is provided at the bottom of the right end of the sorting box 2, a discharge port 24 is provided at the bottom of the sorting box 2, and a material receiving conveyor belt 2 92 and a material receiving conveyor belt 1 91 are respectively arranged below the discharge port 23 and the discharge port 24;

[0027] The sorting structure 7 includes a driven roller 74 rotatably mounted inside the sorting chamber 22, a magnetic ring 75 is fixed to the outer wall of the driven roller 74, one end of the driven roller 74 is fixedly connected to a driven wheel 2 73, the driven wheel 2 73 is mounted at the front end of the sorting box 2, the driven wheel 2 73 is connected to the driving wheel 2 71 through a transmission belt 2 72, and the driving wheel 2 71 is fixed on the crushing structure 5;

[0028] A scraper 25 is fixed to the inner wall of the discharge port 24 , and the upper end of the scraper 25 is in contact with the outer wall of the magnetic ring 75 .

[0029] In this embodiment, the waste is put into the crushing chamber 11 of the crushing box 1. The crushing structure 3 performs preliminary crushing on the waste, crushing it into smaller particles for subsequent processing.

[0030] The waste after preliminary crushing is transported to the crushing chamber 21 of the sorting box 2 through the transport chamber 12. In the crushing chamber 21, the waste is further crushed to ensure that its particle size meets the requirements of subsequent sorting.

[0031] The pulverized waste enters the sorting chamber 22 through the filter plate 67. In the sorting chamber 22, the sorting structure 7 starts to work, the pulverizing structure 5 drives the driven roller 74 to rotate, and the driven roller 74 drives the magnetic ring 75 to rotate. The magnetic ring 75 uses its magnetic properties to absorb the metal components in the waste. At the same time, the driving wheel 2 71 drives the driven wheel 2 73 and the driven roller 74 to rotate through the transmission belt 2 72, so as to realize the continuous operation of the magnetic ring 75. The metal components adsorbed by the magnetic ring 75 are brought to the vicinity of the discharge port 24 as the driven roller 74 rotates. Since the scraper 25 fits the outer wall of the magnetic ring 75, the scraper 25 will scrape off the metal components attached to the surface of the magnetic ring 75 and discharge it from the discharge port 24. The waste with non-metallic components is discharged through the discharge port 23 under the action of gravity.

[0032] Finally, the sorted wastes are discharged through the discharge port 23 and the discharge port 24 respectively, and are collected and transported by the receiving conveyor belt 2 92 and the receiving conveyor belt 1 91 .

[0033] In an optional embodiment, the crushing structure 5 includes a crushing piece 51 and a crushing piece 54 rotatably installed inside the crushing chamber 21, one end of the crushing piece 51 extends to the rear end of the sorting box 2 and is fixedly connected to the output end of the motor 2 56, one end of the crushing piece 54 extends to the rear end of the sorting box 2 and is fixedly connected to the rotating disk 55, the other ends of the crushing piece 51 and the crushing piece 54 extend to the front end of the sorting box 2 and are respectively fixed with a gear 52 and a gear 2 53, the gear 1 52 is fixed to the driving wheel 2 71, the gear 1 52 is meshed with the gear 2 53, and the gear 2 53 and the rotating disk 55 are connected to the reciprocating structure 6.

[0034] It should be noted that when the motor 2 56 is started, the crushing element 1 51 starts to rotate, and through the meshing transmission of the gear 1 52 and the gear 2 53, the crushing element 2 54 and the rotating disk 55 are driven to rotate synchronously, thereby driving the reciprocating structure 6 to operate.

[0035] In an optional embodiment, the reciprocating structure 6 includes a fixed rod 61 fixed to the outer circumferential surface of the gear 2 53 and the rotating disk 55, the fixed rod 61 is slidably installed inside the movable frame 62, one end of the movable frame 62 is fixedly connected to the reciprocating rod 65 through the connecting rod 63, the reciprocating rod 65 is slidably installed inside the reciprocating frame 64, the reciprocating frame 64 is fixed on the left side of the sorting box 2, an L-shaped plate 66 is fixed at the lower end of the reciprocating rod 65, the other end of the L-shaped plate 66 is fixedly connected to the filter plate 67, and the other end of the filter plate 67 is connected to the blowing structure 8 through the connecting block 68.

[0036] It should be noted that when the crushing element 54 and the rotating disk 55 rotate, the fixed rod 61 rotates accordingly and slides in the movable frame 62. This sliding motion is converted into a reciprocating motion of the reciprocating rod 65 in the reciprocating frame 64 through the connecting rod 63. Finally, the L-shaped plate 66 drives the filter plate 67 to reciprocate and vibrate, which helps to screen and separate waste.

[0037] In an optional embodiment, the blowing structure 8 includes an air cavity 26 and an installation cavity 27 opened inside the sorting box 2, a piston block 82 is slidably arranged inside the air cavity 26, and one end of the piston block 82 away from the air cavity 26 is fixed to the connecting block 68 through a piston rod 81, a one-way air inlet valve 83 is arranged at the upper end of the air cavity 26 to communicate with the outside, a filter screen 1 84 is arranged on the one-way air inlet valve 83, the air cavity 26 is connected to the jet component 87 through a connecting pipe 86, the jet component 87 is installed inside the installation cavity 27, a one-way air outlet valve 85 is arranged at the connection between the air cavity 26 and the connecting pipe 86, the jet port of the jet component 87 faces the filter plate 67, and a filter screen 2 88 is arranged at the jet port position of the jet component 87.

[0038] It should be noted that when the filter plate 67 vibrates, the piston block 82 is driven to slide in the air cavity 26 through the connecting block 68 and the piston rod 81. When the piston block 82 moves to the outside of the air cavity 26, the one-way air inlet valve 83 opens, allowing the outside air (filtered by the filter screen 84) to enter the air cavity 26. When the piston block 82 moves to the inside of the air cavity 26, the one-way air outlet valve 85 opens, and the gas enters the jet part 87 through the connecting pipe 86 and sprays out the airflow toward the filter plate 67. This airflow helps to further clean the residue on the filter plate 67 and improve the screening efficiency.

[0039] In an optional embodiment, the crushing structure 3 includes two crushing parts 31 rotatably installed inside the crushing chamber 11, one end of the two crushing parts 31 extends to the front end of the crushing box 1 and is fixedly connected to a gear part 32, the two gear parts 32 are meshed with each other, and a driving wheel 33 is fixed at one end of one gear part 32, the driving wheel 33 is fixed to the output end of a motor 34, and the driving wheel 33 is connected to the transport structure 4 through a transmission belt 35.

[0040] It should be noted that when the motor 1 34 is started, the driving wheel 1 33 drives the transmission belt 1 35 to rotate, thereby driving the two crushing members 31 to rotate toward each other through the meshing of the gear member 1 32. This design allows the waste to be fully crushed in the crushing chamber 11.

[0041] In an optional embodiment, the transport structure 4 includes a driven wheel 41 installed at the front end of the crushing box 1, and the driven wheel 41 is connected to the driving wheel 33 through a transmission belt 35. One end of the driven wheel 41 extends to the inside of the transport cavity 12 and is fixedly connected to a transport roller 42. A plurality of transport spacers 43 are fixed at equal angles on the outer wall of the transport roller 42, and a transport groove 44 is arranged between every two transport spacers 43.

[0042] It should be noted that the crushed waste is driven by the transport spacer 43 and the transport trough 44 on the transport roller 42 through the transport chamber 12, and moves downward along the transport chamber 12 until it enters the crushing chamber 21 for further processing. In this process, the waste is contained in the transport trough 44, ensuring that the amount of waste transported to the crushing chamber 21 each time remains consistent, which not only optimizes the crushing efficiency, but also ensures the continuity and stability of the subsequent processing steps.

[0043] The above embodiment discloses a solid waste sorting and recycling device for a power plant, wherein the waste is put into the crushing chamber 11 of the crushing box 1. The crushing structure 3 performs preliminary crushing on the waste, crushing it into smaller particles for subsequent processing.

[0044] Specifically, when the motor 34 is started, the driving wheel 33 drives the transmission belt 35 to rotate, and then drives the two crushing parts 31 to rotate towards each other through the meshing of the gear part 32, so that the waste is fully crushed in the crushing chamber 11.

[0045] The crushed waste passes through the transport chamber 12 and is driven by the transport spacers 43 and the transport troughs 44 on the transport rollers 42 , and moves downward along the transport chamber 12 until entering the crushing chamber 21 for further processing.

[0046] When the motor 2 56 is started, the crushing element 1 51 starts to rotate, and through the meshing transmission of the gear 1 52 and the gear 2 53 , the crushing element 2 54 and the rotating disk 55 are driven to rotate synchronously, thereby driving the reciprocating structure 6 to operate.

[0047] When the crushing element 2 54 and the rotating disk 55 rotate, the fixed rod 61 rotates accordingly and slides in the movable frame 62. This sliding motion is converted into a reciprocating motion of the reciprocating rod 65 in the reciprocating frame 64 through the connecting rod 63. Finally, the L-shaped plate 66 drives the filter plate 67 to reciprocate and vibrate, which helps to screen and separate waste.

[0048] When the filter plate 67 vibrates, the piston block 82 is driven to slide in the air cavity 26 through the connecting block 68 and the piston rod 81. When the piston block 82 moves to the outside of the air cavity 26, the one-way air inlet valve 83 opens, allowing the outside air (filtered by the filter screen 84) to enter the air cavity 26. When the piston block 82 moves to the inside of the air cavity 26, the one-way air outlet valve 85 opens, and the gas enters the jet part 87 through the connecting pipe 86 and sprays out the airflow toward the filter plate 67. This airflow helps to further clean the residue on the filter plate 67 and improve the screening efficiency.

[0049] The motor 2 56 drives the gear 1 52 to drive the driving wheel 2 71 to rotate. The driving wheel 2 71 is connected to the driven wheel 2 73 through the transmission belt 2 72, thereby driving the driven roller 74 to rotate. The driven roller 74 drives the magnetic ring 75 to rotate. The magnetic ring 75 uses its magnetic properties to absorb the metal components in the waste. At the same time, the driving wheel 2 71 drives the driven wheel 2 73 and the driven roller 74 to rotate through the transmission belt 2 72, so as to realize the continuous operation of the magnetic ring 75. The metal components adsorbed by the magnetic ring 75 are brought to the vicinity of the discharge port 24 as the driven roller 74 rotates. Since the scraper 25 fits the outer wall of the magnetic ring 75, the scraper 25 will scrape off the metal components attached to the surface of the magnetic ring 75 and discharge it from the discharge port 24. The waste with non-metallic components is discharged through the discharge port 23 under the action of gravity.

[0050] Finally, the sorted wastes are discharged through the discharge port 23 and the discharge port 24 respectively, and are collected and transported by the receiving conveyor belt 2 92 and the receiving conveyor belt 1 91 .

[0051] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
