Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Specific Implementation Example 1:

[0029] Please see Figure 1-6 As shown, this utility model is a construction waste sorting and recycling device, including a sorting machine 1, a cyclone dust collector 2, an ash discharge valve 3, and a centrifugal fan 4. The sorting machine 1 includes a sorting box 11, a feeding bin 12, a guide plate assembly 13, and an iron removal assembly 14. The sorting box 11 includes a rectangular box 111. The feeding bin 12 is fixedly installed through and on the top left side of the rectangular box 111. The right end face of the rectangular box 111 has a heavy waste output port 112 and a scrap iron output port 113, with the scrap iron output port 113 located above the heavy waste output port 112. The guide plate assembly 13 is installed inside the sorting box 11 and is inclined from the upper left corner to the lower right corner of the sorting box 11. The iron removal assembly 14 is installed inside the sorting box 11 and is located above the guide plate assembly 13. Two rows of exhaust pipes 114 are fixedly installed through and on the top surface of the rectangular box 111. Two rows of extraction pipes 114 are connected by a main air duct 115, and each main air duct 115 is connected to the air inlet of a cyclone dust collector 2. A discharge valve 3 is installed at the lower end of the cyclone dust collector 2. The upper ends of the two cyclone dust collectors 2 are connected to the air inlet of the centrifugal fan 4 via a T-junction pipe 5. A conveyor is installed below and outside the heavy waste outlet 112, and another conveyor is installed below and outside the scrap iron outlet 113, for conveying and stacking waste.

[0030] The sorting chamber 11 in the sorting machine 1 provides a relatively enclosed environment. The feeding hopper 12 evenly feeds the crushed construction waste onto the guide inclined plate assembly 13 below. During the rotation of the iron removal assembly 14, ferrous metals are adsorbed and discharged from the scrap iron outlet 113. Lighter materials are discharged from the two rows of exhaust pipes 114, while heavier waste is discharged from the heavy waste outlet 112. This process achieves the sorting and recycling of recyclable lightweight combustible materials and scrap iron from construction waste.

[0031] The sorting machine 1, combined with the cyclone dust collector 2, the ash discharge valve 3, and the centrifugal fan 4, can extract lightweight debris such as wood chips, plastic film, and foam from the sorting machine 1 and discharge them through the ash discharge valve 3. After collection and sieving to remove ash and soil, the debris can be compressed, packaged, and sent to incineration power plants for recycling and reuse.

[0032] To facilitate cleaning of the interior of the rectangular box 111, an inspection window 116 is provided on the left end face of the rectangular box 111.

[0033] The feeding hopper 12 includes a rectangular material pipe 121 that is fixedly connected to the top surface of a rectangular box 111. A conical funnel 122 is fixed to the upper end of the rectangular material pipe 121, and the crushed construction waste is dumped into the conical funnel 122 using a conveyor or a loader. Inclined feeding plates 123, which are inclined towards the left side of the rectangular box 111, are fixed to the front, rear, inner walls, and right wall of the rectangular material pipe 121. Two vibrators 124 are installed on the lower surface of the inclined feeding plates 123. To ensure that the material is firmly packed and does not collapse naturally during feeding from the feeding hopper 12, the two vibrators 124 vibrate the crushed construction waste to ensure a stable downward flow.

[0034] The guide plate assembly 13 includes two support strips 131, a guide plate 132, and several springs 133. The upper end of the guide plate 132 is positioned directly below the discharge hopper 12. The lower end of the guide plate 132 passes through the heavy waste outlet 112. The two support strips 131 are fixed between the front and rear inner walls of the rectangular box 111. Several guide holes 134 are evenly distributed along the length of the surface of the support strips 131. Two rows of guide posts 135 are fixed on the lower surface of the guide plate 132, which slide in cooperation with the guide holes 134 on the support strips 131. Springs 133 are fitted on the guide posts 135 between the lower surface of the guide plate 132 and the support strips 131. When the debris trapped between the guide plate 132 and the iron removal component 14 in the guide plate assembly 13 is larger than the gap between them, the guide plate 132 is compressed by the spring 133 and moves downward so that the debris can flow downward smoothly. Under the elastic action of the spring 133, it returns to its original position, ensuring the smooth downward flow of the pulverized building materials so that the ferrous metal and lightweight debris can be separated and recycled in an orderly manner.

[0035] The iron removal assembly 14 includes a geared motor 141, an inner cylinder 142, a stainless steel outer cylinder 143, several semi-circular magnets 144, and a shovel plate 145. A motor mounting base 117 for mounting the geared motor 141 is fixed to the outer wall of the rectangular housing 111. The inner cylinder 142 is fixed between the front and rear inner walls of the rectangular housing 111. A circular disc 146 is fixed to each end of the outer wall of the rectangular housing 111. The circular discs 146 and the stainless steel outer cylinder 143 are rotatably connected via bearings 147. A row of closely arranged semi-circular magnets 144 is evenly distributed and fixed to the outer wall of the inner cylinder 142 between the two circular discs 146. The two end faces of the semi-circular magnets 144 are vertically aligned, and the semi-circular magnets 144 are located on one side of the discharge hopper 12. An internal gear 148 is fixed to the inner wall of one end of the stainless steel outer cylinder 143. The output shaft of the geared motor 141 passes through the outer wall of the rectangular housing 111 and is fitted with an external gear that meshes with the internal gear 148. The shovel plate 145 is fixed to the lower end face of the scrap metal output port 113 and is inclined.

[0036] The geared motor 141 drives the stainless steel outer cylinder 143 to rotate. Within the range of the semi-circular magnet 144 installed on the inner cylinder 142, the scrap iron is attracted to the outer surface of the stainless steel outer cylinder 143. After the scrap iron passes the top of the stainless steel outer cylinder 143, it begins to detach from the stainless steel outer cylinder 143 and slides out of the scrap iron output port 113 along the shovel plate 145. The scrap iron in the construction waste is collected and utilized.
