Technical Field

[0001] This utility model relates to the field of solid waste treatment technology, specifically to a construction solid waste resource recycling device. Background Technology

[0002] With the continuous acceleration of urbanization, the construction industry has developed rapidly, but it has also generated a large amount of construction solid waste. Construction solid waste mainly includes waste concrete, waste bricks and stones, waste steel bars, etc. If these solid wastes are not properly treated and utilized, they will not only occupy a large amount of land resources, but also cause serious pollution to the environment.

Second, the spiral feeder of this utility model can feed the collected non-magnetic waste back into the rectangular crushing shell, so that it can undergo crushing and adsorption by the permanent magnet plate again, which can more thoroughly separate the magnetic waste and improve the degree of recycling of magnetic waste.

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Please refer to the following: Figures 1-7 .

[0018] The construction solid waste recycling equipment includes: a rectangular crushing shell 1, a first support frame 2 and a second support frame 3 fixedly installed on the outer walls of both sides of the rectangular crushing shell 1, a feed hopper 4 fixedly installed on the top of the rectangular crushing shell 1, two crushing rollers 5 rotatably installed inside the rectangular crushing shell 1, each crushing roller 5 having multiple crushing teeth 6 on its outer periphery, and the crushing teeth 6 of the two crushing rollers 5 meshing with each other, and the same-direction ends of the two crushing rollers 5 extending outside the rectangular crushing shell 1, and gears fixedly fitted on the parts of the two crushing rollers 5 located outside the rectangular crushing shell 1, with the two gears meshing with each other, and a first drive motor fixedly installed on one side of the outer wall of the rectangular crushing shell 1, the output shaft of which is fixedly connected to one end of one of the crushing rollers 5. Through the operation of the first drive motor and the meshing of the two gears, the two crushing rollers 5 can be driven to rotate synchronously and relative to each other, thereby realizing the crushing of solid waste; A guide ramp 7 is fixedly installed on the outer wall of the rectangular crushing shell 1 near the first support frame 2. Multiple inclined guide plates 8 are fixedly installed on the inner walls of both sides of the rectangular crushing shell 1, and these inclined guide plates 8 are symmetrically and alternately distributed. This allows the crushed waste to roll multiple times, improving the collection effect of magnetic waste. Furthermore, the uppermost inclined guide plate 8 is located below the guide ramp 7 and is symmetrically and alternately distributed with the guide ramp 7, thus smoothly guiding the crushed waste to the highest point of the uppermost inclined guide plate 8, allowing the waste to start rolling from this highest point. To attract magnetic substances in the waste, multiple permanent magnet plates 10 are provided inside the rectangular crushing shell 1. The magnetic plate 10 is attached to the bottom of multiple inclined guide plates 8. When the waste rolls on the inclined guide plates 8, it can adsorb the magnetic material. A pull-down mechanism is provided on the rectangular crushing shell 1 to separate the permanent magnet plate 10 from the inclined guide plates 8, so that the adsorbed magnetic waste can be discharged smoothly. Two guide channels 18 are provided below the rectangular crushing shell 1. The first belt conveyor group 19 and the second belt conveyor group 20 are respectively provided in the two guide channels 18. A horizontal moving mechanism is provided on the side of the first support frame 2 near the second support frame 3. The horizontal moving mechanism is connected to the two guide channels 18. The two conveying tools can separately convey and recycle non-magnetic and magnetic waste.

[0019] In this embodiment, the aforementioned pull-down mechanism includes a rectangular frame 9 fitted onto the rectangular crushing shell 1. Multiple connecting arms 11 are fixedly installed on the inner walls of both sides of the rectangular frame 9. One side of each connecting arm 11 extends into the rectangular crushing shell 1 and is fixedly connected to a corresponding permanent magnet plate 10. All connecting arms 11 are slidably connected to the rectangular crushing shell 1. A hydraulic cylinder 12 is fixedly installed inside the second support frame 3. A lower pressure plate 13 is fixedly installed on the output shaft of the hydraulic cylinder 12. One side of the lower pressure plate 13 is fixedly connected to one outer wall of the rectangular frame 9. The mechanism is connected via hydraulic... The extension of the output shaft of the pressure cylinder 12 allows multiple permanent magnet plates 10 to descend, thus separating from the inclined guide plate 8. To ensure that the connecting arm 11 can slide smoothly up and down on the rectangular crushing shell 1, multiple sliding openings are provided on both sides of the rectangular crushing shell 1. The multiple connecting arms 11 pass through the multiple sliding openings and contact the inner wall of the corresponding sliding opening. A baffle plate is fixedly fitted on each of the multiple connecting arms 11. The multiple baffle plates contact the outer wall of the rectangular crushing shell 1 and cover the multiple sliding openings to form a baffle effect and prevent waste from leaking out.

[0020] In this embodiment, the aforementioned horizontal moving mechanism includes an open frame 14 fixedly installed on the side of the first support frame 2 near the second support frame 3. A moving screw 15 is rotatably installed inside the open frame 14, and a moving block 16 is threaded onto the moving screw 15. In order to ensure that the moving block 16 forms a linear motion, two limiting single bars are fixed inside the open frame 14. The two limiting single bars pass through the moving block 16 and are slidably connected to it. An mounting plate 17 is fixedly installed on the top of the moving block 16. The bottoms of the two guide channel steels 18 are fixedly connected to the mounting plate 17. A second drive motor is fixedly installed on one outer wall of the open frame 14, and its output shaft is fixedly connected to one end of the moving screw 15.

[0021] In this embodiment, the first belt conveyor group 19 and the second belt conveyor group 20 mentioned above are both composed of a conveyor belt, a conveyor motor, and two conveyor rollers. The two conveyor rollers are rotatably installed inside the guide channel steel 18, and the conveyor belt is sleeved on the two conveyor rollers. The conveyor motor is fixedly installed on one side of the outer wall of the guide channel steel 18, and the output shaft of the conveyor motor is fixedly connected to the end of one of the conveyor rollers. This type of conveying structure is a common type of conveying on the market, and will not be described in detail here. In addition, a receiving frame 21 is provided below the two guide channel steels 18 to collect the conveyed waste. A screw feeder 22 is provided on the side of the first belt conveyor group 19 away from the second belt conveyor group 20. The discharge end of the screw feeder 22 is located above the feed hopper 4. This allows the collected non-magnetic waste to be put back into the rectangular crushing shell 1 to undergo another crushing and magnetic attraction process, thereby increasing the amount of magnetic waste collected.

[0022] The working principle of the construction solid waste recycling equipment provided by this utility model is as follows: In its initial state, the first belt conveyor unit 19 is located below the discharge port of the lowest inclined guide plate 8; When in use, first start the first drive motor. The meshing of the two gears will drive the two crushing rollers 5 to rotate synchronously and relative to each other. Then, pour the solid waste into the rectangular crushing shell 1 through the feed hopper 4 and crush the solid waste using the crushing teeth 6. The crushed waste will fall onto the first inclined guide plate 8 through the guide plate 7 and continue to roll, and then roll on the remaining few inclined guide plates 8 in turn, and finally fall onto the first belt conveyor 19 and be conveyed to the receiving frame 21. During the rolling process on the inclined guide plate 8, the waste is attracted by the magnetism of the permanent magnet plate 10, and the magnetic metal waste in the waste will be adsorbed onto the inclined guide plate 8. After the solid waste crushing is completed, the receiving frame 21 under the first belt conveyor unit 19 is pulled away and a new empty receiving frame 21 is placed. Then, the receiving frame 21 containing non-magnetic waste is tilted and aligned with the feed end of the screw feeder 22. The waste is poured into the screw feeder 22 and then enters the rectangular crushing shell 1 again through the discharge end of the screw feeder 22. This allows the crushed waste to undergo crushing and rolling again, which can more thoroughly adsorb the magnetic waste mixed in onto the inclined guide plate 8. After the above steps are completed, the second drive motor can be started in the forward direction. Its output shaft drives the moving screw 15 to rotate, and the moving block 16 with its threaded mounting moves horizontally with the two guide channel steels 18. Finally, the second belt conveyor 20 is moved to below the discharge port of the lowest inclined guide plate 8. Then, the output shaft of the hydraulic cylinder 12 is extended, and the rectangular frame sleeve 9 lowers the three connecting arms 11, thereby separating the permanent magnet plate 10 from the inclined guide plate 8. After separation, the magnetic metal waste on the inclined guide plate 8 will automatically roll down and finally fall into the second belt conveyor 20 and be conveyed to the receiving frame 21 below the outlet of the second belt conveyor 20. After discharge, the second drive motor is started in reverse to bring the two guide troughs 18 back to their initial positions. Then, the output shaft of the hydraulic cylinder 12 is retracted to make the permanent magnet plate 10 fit with the inclined guide plate 8 again, so that the next batch of solid waste can continue to be crushed and recycled.

[0023] Compared with related technologies, the construction solid waste recycling equipment provided by this utility model has the following beneficial effects: I. This utility model, by setting a permanent magnet plate 10 at the bottom of the inclined guide plate 8, allows solid waste to be crushed and then rolled sequentially on multiple inclined guide plates 8, thereby adsorbing magnetic metal waste and discharging non-magnetic waste through the first belt conveyor unit 19. After the crushing operation is completed, the permanent magnet plate 10 is separated from the inclined guide plate 8, allowing the magnetic waste to be discharged through the second belt conveyor unit 20. This separates the non-magnetic and magnetic waste for collection, which is beneficial for subsequent recycling of the two types of waste. At the same time, compared with the traditional method of crushing first and then transferring to magnetic separation equipment for magnetic separation, this method is faster and improves recycling efficiency. Second, the spiral feeder 22 of this utility model can feed the collected non-magnetic waste back into the rectangular crushing shell 1, so that it can undergo crushing and adsorption by the permanent magnet plate 10 again, which can more thoroughly separate the magnetic waste and improve the degree of recycling of magnetic waste.
