Description

Technical Field

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

[0002] Solid waste refers to solid and semi-solid materials that have lost their original utilization value or have not lost their utilization value but have been discarded or abandoned, as well as gaseous items and substances placed in containers, and items and substances that are included in waste management as required by laws and administrative regulations. According to their source and nature, solid waste can be divided into domestic waste, construction waste, industrial solid waste, agricultural solid waste and hazardous waste.

[0003] After searching, the Chinese patent with publication number CN220658723U discloses a solid waste garbage classification and collection device, including a recycling box, a feed hopper is fixedly installed on the upper side wall of the recycling box, and a second gear is sleeved on the outer side wall of the first motor output shaft, and the second gear is meshed with the first gear. When the solid waste is recycled, large-sized waste is left on the surface of the sieve, and small-sized waste passes through the inner cavity of the sieve and falls on the surface of two crushing rollers. The small-sized solid waste is crushed by the two relatively rotating crushing rollers, and the large-sized waste retained on the surface of the sieve is driven by the active end of the electric push rod to move the push plate, and the retained solid waste is pushed out of the outside through the push plate, so that the solid waste is discharged to the outside through the discharge port. By classifying and recycling the solid waste, the efficiency of the waste treatment process is improved, and the processing operation process of the relevant personnel is convenient. However, the scheme still has the following shortcomings when it is actually used: In the field of solid waste recycling, for the treatment and recycling of specific types such as construction waste, although the existing technology identifies and picks out large waste as a preliminary classification step, it fails to achieve a deeper level of fine classification and recycling of special components that may be contained in these solid wastes, such as metal substances. This limitation significantly reduces the practicality and efficiency of the recycling process, because construction waste is often mixed with a large amount of recyclable metals, such as steel bars, aluminum parts and waste pipes. If these metals can be effectively separated and recycled, it will not only significantly reduce the demand for mining of primary mineral resources, but also bring considerable economic benefits to enterprises, while reducing the pollution burden on the environment.

[0004] Therefore, the present application provides a classification device for solid waste recycling to meet the purpose of sorting metal substances. Summary of the invention

[0024] like Figures 1 to 8As shown, a classification device for solid waste recycling comprises a sorting frame 1; a conveying structure 2, which is arranged on the inner side wall of the sorting frame 1; a connecting seat 3, which is fixedly installed on the side of the sorting frame 1, and a blanking plate 13 is fixedly installed between the connecting seat 3 and the sorting frame 1, and the blanking plate 13 is arranged in an inclined manner; a top frame 4, which is fixedly installed on the top surface of the connecting seat 3; a turntable 1 5, which is rotatably installed on one side of the bottom surface of the top frame 4; a turntable 2 6, which is rotatably installed on the other side of the bottom surface of the top frame 4; a sorting assembly, which is arranged on the top surface of the connecting seat 3; an electromagnetic sorting plate 8, which is arranged on the sorting assembly; a spreading plate 10, which is arranged at a position directly above the conveying structure 2, and a plurality of tooth comb grooves distributed in a linear array are opened at the bottom of the spreading plate 10; a spreading assembly, which is arranged at a position corresponding to the top surface of the sorting frame 1 and the spreading plate 10; a support plate 11, which is fixedly installed on one side of the top surface of the sorting frame 1; a pre-selection assembly, which is arranged between the sorting frame 1 and the support plate 11; First, the solid waste to be recycled can be added to the conveying structure 2 on the sorting frame 1 through a loading device, and the conveying structure 2 can be opened to convey the solid waste. In the process of conveying the solid waste through the conveying structure 2, the solid waste on the conveying structure 2 can be sorted by a pre-selection component first, so that larger solid waste can be sorted out. Then, the solid waste can be evenly spread on the conveying structure 2 through the use of a spreading component and a spreading plate 10 for subsequent sorting. The spread solid waste can pass directly under the electromagnetic sorting plate 8, and the metal material can be adsorbed under the magnetic force of the electromagnetic sorting plate 8. The metal waste adsorbed by the electromagnetic sorting plate 8 is guided to the outside of the sorting frame 1 through the sorting component and discharged separately through the blanking plate 13, thereby realizing the classified recycling of solid waste.

When the turntable 2 6 rotates, the guide groove 1 74 on its side can drive the guide wheel 1 76 to slide along the guide groove 1 74, and during the sliding process, the connecting frame 75 can be driven to reciprocate. The other end of the connecting frame 75 is vertically slidably connected to the sliding seat 72 through the sliding groove 1 73 and the slider 77. Therefore, during the reciprocating rotation of the connecting frame 75, the sliding seat 72 can be driven to reciprocate horizontally along the connecting seat 3.

[0026] like Figures 3 to 6 As shown, the connection mechanism includes: a lifting plate 78, which is slidably mounted on the end of the sliding seat 72 away from the turntable 6; a second slide groove 79, which is arranged on the side of the lifting plate 78; a guide arm 710, which is hinged on the inner wall of the top frame 4; a rotating shaft 711, which is arranged through the end of the guide arm 710 away from the top frame 4; a second guide groove 712, which is arranged on the side of the turntable 5 opposite to the sliding seat 72, and one end of the rotating shaft 711 is slidably connected to the inner wall of the second guide groove 712; a second guide wheel 713, which is fixedly mounted on the end of the rotating shaft 711 away from the second guide groove 712, and the second guide wheel 713 is slidably connected to the second slide groove 79; a support arm 714, which is fixedly mounted on the side of the lifting plate 78 and located below the second slide groove 79, and the end of the support arm 714 away from the lifting plate 78 is fixedly connected to the top surface of the electromagnetic sorting plate 8; During the rotation of the turntable 1 5, the guide groove 2 712 on the side can drive the rotating shaft 711 to slide along the guide groove 2 712, and the rotating shaft 711 is hinged to the side of the top frame 4 through the guide arm 710, so that during the sliding of the rotating shaft 711 along the guide groove 2 712, the guide arm 710 can swing back and forth, and during the swinging of the guide arm 710, the sliding of the guide wheel 2 713 in the slide groove 2 79 can drive the lifting plate 78 to slide back and forth in the vertical direction along the sliding seat 72, and the rotation of the turntable 2 6 can make the sliding seat 72 slide back and forth in the horizontal direction. The electromagnetic sorting plate 8 can slide vertically back and forth at the two end positions of the sliding seat 72, so that the electromagnetic sorting plate 8 can move upward just above the conveying structure 2, and then move horizontally out of the sorting frame 1 and move downward. At this time, the electromagnetic sorting plate 8 can be powered off so that the metal waste falls onto the blanking plate 13. After completion, the electromagnetic sorting plate 8 can move upward and slide horizontally in the opposite direction to reset. When the electromagnetic sorting plate 8 is reset to just above the conveying structure 2, the electromagnetic sorting plate 8 continues to be powered on to adsorb the metal waste. The working principle and connection method of the electromagnetic sorting plate 8 are existing mature technologies and will not be elaborated on here.

The worm 99 on the transmission shaft 98 is meshed with the worm wheel 910 on the driving disk 95, so that the driving disk 95 can be driven to rotate, thereby driving the driving disk 95.

[0029] like Figure 2 , Figure 8As shown, the pre-selection assembly includes: a mounting plate 121, fixedly mounted on the top surface of the sorting frame 1; a support rod 122, which is arranged on the side of the mounting plate 121, and the support rod 122 is rotatably connected to the penetration, and the support rod 122 and the driving disk 95 are connected to each other through a driven wheel and a synchronous belt transmission; an eccentric wheel 123, fixedly mounted on the end of the support rod 122; a set frame 124, which is set on the outer wall of the eccentric wheel 123; a fixing rod 125, fixedly mounted on the side position of the mounting plate 121 At the position directly above the support rod 122; the slot 126 is opened at the top of the set frame 124, and the fixing rod 125 is movably connected to the slot 126; the large piece sorting plate 127 is fixedly installed on the side of the set frame 124, and the end of the large piece sorting plate 127 away from the set frame 124 is slidably connected to the support plate 11, and the large piece sorting plate 127 is set to be conical; two blanking ports 128 are symmetrically opened at the top surface of the sorting frame 1 and the corresponding positions of the two ends of the large piece sorting plate 127; When the driving disk 95 is driven, the support rod 122 on the mounting plate 121 can be driven to rotate through the synchronous belt and the driven wheel.
