Description

Technical Field

[0001] This utility model belongs to the field of construction waste treatment technology, and in particular relates to a construction waste treatment device. Background Technology

[0002] With the rapid urbanization and development of the construction industry, a large amount of construction waste has been generated. How to efficiently handle this waste has become one of the most pressing issues in the environmental protection field. Currently available construction waste processing equipment mainly focuses on large-scale mechanical crushers and sorting lines. While these can reduce waste volume to a certain extent, they are costly, complex to operate, inconvenient for small construction sites, and have limited ability to finely separate mixed waste, failing to meet the needs of resource recycling. To address these challenges, the industry has proposed several different processing methods. For example, some manufacturers have developed mobile crushing plants that can be quickly moved to different construction sites, improving flexibility; others have developed automatic sorting machines based on photoelectric recognition technology, which distinguish different types of materials by color, shape, and other factors, improving recycling rates. However, these traditional processing methods still have many limitations. Mobile crushing plants are bulky, difficult to operate in confined spaces, and cause significant noise pollution; photoelectric sorting machines require huge initial investments, have high maintenance costs, and are susceptible to environmental interference that can lead to decreased recognition accuracy. Overall, existing construction waste treatment technologies generally suffer from low efficiency, narrow applicability, and poor economic performance, especially in small-scale construction sites. Furthermore, many devices can only perform a single function (such as crushing or screening), lacking integrated solutions and failing to achieve effective control over the entire process from source to end.

[0003] Chinese patent CN218901957U discloses a construction waste processing device. The device includes a base plate, a housing, a first rotary motor, a bidirectional threaded rod, support blocks, sliders, a second rotary motor, a rotating rod, crushing rollers, and limiting blocks. Four support legs are fixedly connected to the upper surface of the base plate. The first rotary motor and support blocks are fixedly connected to the front of the housing. The bidirectional threaded rod is rotatably connected to the support blocks. Two sliders are threadedly connected to the outer surface of the bidirectional threaded rod, and both sliders are slidably connected to the housing. The upper surfaces of both sliders are fixedly connected to the second rotary motor, and rotating rods are fixedly connected to the output shafts of both second rotary motors. Two limiting blocks are slidably connected to the inner wall of the housing, and each limiting block is rotatably connected to one of the two crushing rollers. Through these cooperating components, the axial distance between the two crushing rollers can be adjusted as needed to crush construction waste into different diameters, thus enhancing the applicability of the construction waste processing device. The device is not convenient for separating metal waste from the crushed construction waste, which affects the treatment effect of construction waste and makes it difficult to achieve better practicality. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned technical problems by providing a construction waste treatment device. This device effectively solves the problem that during the use of construction waste treatment devices, it is not easy to separate metal waste from the crushed construction waste, which affects the treatment effect of construction waste and thus facilitates better practicality.

[0005] In view of this, the present invention provides a construction waste treatment device including a support column, a crushing box fixedly mounted on the support column; a tilting assembly disposed on one side of the crushing box, the tilting assembly pouring construction waste into the crushing box; a splash-proof assembly disposed on the top of the crushing box, the splash-proof assembly preventing construction waste from splashing during crushing; crushing rollers symmetrically disposed inside the crushing box; an electromagnetic grid disposed below the crushing rollers, the electromagnetic grid being disposed inside the crushing box; a first outlet disposed on the side wall of the crushing box; and a second outlet disposed at the bottom of the crushing box. A guide plate is disposed between the first and second outlets, the guide plate being rotatably disposed inside the crushing box.

[0006] In this technical solution, the dumping component transports construction waste to the top of the crushing chamber and pours it into the chamber. During crushing, the construction waste may generate flying debris; the splash-proof component bounces this debris back into the crushing chamber. An electromagnetic grid, when energized, generates magnetic force to attract metallic waste. A guide plate directs the construction waste to the first outlet. Once all non-metallic construction waste is discharged, the electromagnetic grid is no longer energized and stops attracting metallic waste; the guide plate then directs the metallic waste to the second outlet. This separation of metallic waste from the construction waste improves the processing efficiency and achieves better practicality.

[0007] In the above technical solution, further, hydraulic telescopic columns are symmetrically arranged at the bottom of the guide plate, the hydraulic telescopic columns are fixedly arranged at the bottom of the crushing box, and the output end of the hydraulic telescopic columns is arranged at the bottom of the guide plate. When the hydraulic telescopic rod extends, the guide plate corresponds to the first outlet, and when the hydraulic telescopic rod retracts, the guide plate corresponds to the second outlet.

[0008] In this technical solution, the hydraulic telescopic rod drives the guide plate to rotate inside the crushing box through its own extension and retraction. When the electromagnetic grid is energized, it magnetically attracts the metal waste, and the hydraulic telescopic rod extends. The guide plate guides the non-metallic construction waste to the first outlet. When all the non-metallic construction waste is discharged, the electromagnetic grid is de-energized and no longer magnetically attracts the metal waste. The hydraulic telescopic rod retracts, and the extension and retraction of the hydraulic telescopic rod controls the rotation of the guide plate.

[0009] In the above technical solution, the tilting assembly further includes a support base, which is fixedly mounted on one side of the crushing chamber. A first drive motor is mounted on the support base, and a first sprocket is coaxially connected to the first drive motor. The first sprocket is connected to a second sprocket via a first chain. The second sprocket is rotatably mounted on the top of the lifting slide rod. A lifting slider is fixedly mounted on the first chain and slidably mounted on the lifting slide rod. The lifting slide rod is vertically mounted on the support base. A carrying box is mounted on one side of the lifting slider, and the carrying box is equipped with a tilting unit that tilts the carrying box.

[0010] In this technical solution, a first drive motor drives a first sprocket to rotate, the first sprocket drives a first chain to rotate between the first sprocket and the second sprocket, the first chain drives a lifting slider to slide at a certain height on a lifting slide bar, and the first drive motor drives the carrying box to move at a certain height through the first lifting slider. The carrying box is loaded with construction waste, raising the construction waste on the ground to the top of the crushing box, which reduces manual labor and improves processing efficiency.

[0011] In the above technical solution, the tilting unit further includes an L-shaped slide groove, which is vertically placed on the support base. A first sliding cylinder is slidably arranged in the L-shaped slide groove. The first sliding cylinder is fixedly arranged on the top of the reversing plate. A first fixed cylinder is fixedly arranged on the bottom of the reversing plate. The first fixed cylinder is rotatably arranged on the bearing box. A second fixed cylinder is rotatably arranged on the side of the bearing box away from the first fixed cylinder. The other end of the second fixed cylinder is fixedly arranged on the lifting slider.

[0012] In this technical solution, during the upward movement of the carrying box, the first fixed column and the second fixed column rise synchronously. When the first sliding cylinder contacts the top of the L-shaped chute, the vertical displacement is converted into a horizontal displacement. The first sliding cylinder causes the first fixed column to act on the carrying box through the reversing plate, causing the carrying box to rotate on the second fixed column. The first motor drives the first fixed column to continue to rise, and the rotation angle of the carrying box increases, so that the construction waste in the carrying box is poured into the crushing box.

[0013] In the above technical solution, a guide channel is further provided on the top of the crushing box to guide the dumped construction waste into the crushing box.

[0014] In this technical solution, the guide channel guides the construction waste poured out of the carrying box, so that the construction waste is poured into the crushing box in a better manner.

[0015] In the above technical solution, the splash-proof component further includes a partition plate, which is symmetrically arranged on the top of the crushing chamber and rotatably arranged inside the crushing chamber. A guide rod is fixedly arranged at the bottom of the partition plate and slidably arranged in a guide cylinder. A return spring is arranged inside the guide cylinder and is in a compressed state. The guide cylinder is fixedly arranged on the inner wall of the crushing chamber.

[0016] In this technical solution, construction waste falls onto the partition plate. Due to the gravity of the construction waste, the return spring is squeezed and contracted, and the partition plate rotates downward to reveal the feed inlet. The construction waste enters the crushing box through the feed inlet. When there is no construction waste on the partition plate, the return spring rebounds, causing the partition plate to seal the top of the crushing box. During the crushing process, not only is it possible to avoid the splashing of debris, but also to avoid the flying of dust.

[0017] In the above technical solution, one end of the crushing roller is coaxially connected to a first support rod, and the other end is coaxially connected to a second support rod. The first support rod passes through the first sliding groove and is rotatably mounted on the first slider. A second drive motor and a third drive motor are respectively fixedly mounted on the two first sliders. The output ends of the second drive motor and the third drive motor are coaxially connected to the first support rod.

[0018] In this technical solution, the output ends of the second drive motor and the third drive motor rotate relative to each other, and the second drive motor and the third drive motor drive the crushing roller to rotate relative to each other, so as to better crush the construction waste.

[0019] In the above technical solution, the first slider is threadedly connected to the first screw, the first screw is rotatably mounted on the limiting block, the first screw is coaxially connected to a driving unit, the driving unit drives the first screw to rotate, the limiting block is fixedly mounted on the outer wall of the crushing box, the second support rod is rotatably mounted on the second slider, and the second slider is slidably mounted in the second groove.

[0020] In this technical solution, the first screw is provided with a bidirectional thread. The drive unit drives the first screw to rotate, causing the two first sliders to slide relative to each other, which in turn causes the crushing rollers to slide relative to each other in the crushing box. This adjusts the distance between the two crushing rollers, controls the size of the crushed construction waste, and improves the usability of the device.

[0021] In the above technical solution, the driving unit further includes a fourth driving motor, the fourth driving unit is fixedly mounted on the limiting block, and the output end of the fourth driving motor passes through the limiting block and is coaxially connected to the first screw.

[0022] In this technical solution, the fourth drive motor drives the first screw to rotate. The first screw is provided with a bidirectional thread. The first screw drives the crushing roller to slide relative to each other in the crushing box through the first slider, thereby adjusting the distance between the two crushing rollers and controlling the size of the crushed construction waste, thus improving the usability of the device.

[0023] The beneficial effects of this utility model are:

[0024] 1. By setting an inclined unit, the greater the distance between the first fixed column and the second fixed column, the more the entire bearing box rotates, pouring the construction waste inside the bearing box into the crushing box.

[0025] 2. By setting up splash-proof components, the partition plate seals the top of the crushing box, which not only prevents debris from flying but also prevents dust from flying during the crushing process.

[0026] 3. By setting up hydraulic telescopic columns, the hydraulic telescopic rods extend, and the guide plate guides the remaining construction waste to the first outlet. When the electromagnetic grid is energized, it no longer magnetically attracts the metal waste, the hydraulic telescopic rods retract, and the guide plate guides the metal waste to the second outlet, thus separating the metal waste from the crushed construction waste.

[0044] Example 1:

[0045] This embodiment provides a construction waste treatment device, such as... Figure 1As shown, the device includes a support column 1, a crushing box 2 fixedly mounted on the support column 1; a tilting assembly located on one side of the crushing box 2, used to pour construction waste into the crushing box 2; a splash-proof assembly located on the top of the crushing box 2, used to prevent construction waste from splashing during crushing; a crushing roller 21 symmetrically arranged inside the crushing box 2; an electromagnetic grid 22 located below the crushing roller 21 inside the crushing box 2; a first outlet 23 located on the side wall of the crushing box 2; and a second outlet 24 located at the bottom of the crushing box 2.

[0046] A guide plate 25 is installed between the first outlet 23 and the second outlet 24, and the guide plate 25 is rotatably mounted inside the crushing chamber 2. The tilting assembly transports the construction waste to the top of the crushing chamber 2 and pours it into the chamber. During crushing, the construction waste may generate flying debris; the anti-splash assembly bounces this debris back into the crushing chamber 2. The electromagnetic grid 22, when energized, generates magnetic force to attract the metal waste. The guide plate guides the construction waste into the first outlet 23. After the construction waste is crushed, the electromagnetic grid 22 is no longer energized and no longer attracts the metal waste. The guide plate 25 guides the metal waste into the second outlet 24. This separation of the metal waste from the construction waste improves the processing efficiency and achieves better practicality.

[0047] like Figure 6 As shown, hydraulic telescopic columns 26 are symmetrically arranged at the bottom of the guide plate 25. The hydraulic telescopic columns 26 are fixedly installed at the bottom of the crushing box 2, and the output end of the hydraulic telescopic columns 26 is located at the bottom of the guide plate 25. When the hydraulic telescopic rod 26 extends, the guide plate 25 corresponds to the first outlet 23; when the hydraulic telescopic rod 26 retracts, the guide plate 25 corresponds to the second outlet 24. The hydraulic telescopic rod drives the guide plate 25 to rotate inside the crushing box 2 through its own extension and retraction. When the electromagnetic grid 22 is energized, it magnetically attracts the metal waste, the hydraulic telescopic rod extends, and the guide plate 25 guides the non-metallic construction waste to the first outlet 23. When all the non-metallic construction waste is discharged, the electromagnetic grid 22 is de-energized and no longer magnetically attracts the metal waste, the hydraulic telescopic rod retracts, and the guide plate 25 guides the metal waste to the second outlet 24. The extension and retraction of the hydraulic telescopic rod 26 controls the rotation of the guide plate 25.

[0048] like Figure 2-3As shown, the tilting assembly includes a support base 4, which is fixedly mounted on one side of the crushing chamber 2. A first drive motor 5 is mounted on the support base 4, and the output of the first drive motor 5 is connected to a lifting slider 6. The lifting slider 6 is slidably mounted on a lifting rod 8, which is vertically mounted on the support base 4. A carrying box 7 is mounted on one side of the lifting slider 6, and the carrying box 7 is equipped with a tilting unit that tilts the carrying box 7. The first drive motor 5 drives the carrying box 7 to move vertically through the first lifting slider 6. The carrying box 7 is loaded with construction waste, raising the construction waste on the ground to the top of the crushing chamber 2, reducing manual labor and improving processing efficiency.

[0049] like Figure 4-5 As shown, a first drive motor 5 is coaxially connected to a first sprocket 32. The first sprocket 32 ​​is connected to a second sprocket 33 via a first chain 34. The second sprocket 33 is rotatably mounted on the top of the lifting slide bar 8. A lifting slider 6 is fixedly mounted on the first chain 34. The first drive motor 5 drives the first sprocket 32 ​​to rotate, which in turn drives the first chain 34 to rotate between the first sprocket 32 ​​and the second sprocket 33. The first chain 34 then drives the lifting slider 6 to slide vertically along the lifting slide bar 8.

[0050] like Figure 2 As shown, the tilting unit includes an L-shaped slide groove 9, which is vertically placed on the support base 4. A first sliding cylinder 14 is slidably disposed in the L-shaped slide groove 9. The first sliding cylinder 14 is fixedly disposed on the top of the reversing plate 15. A first fixed cylinder 17 is fixedly disposed on the bottom of the reversing plate 15. The first fixed cylinder 17 is rotatably disposed on the bearing box 7. A second fixed cylinder 16 is rotatably disposed on the side of the bearing box 7 away from the first fixed cylinder 17. The other end of the second fixed cylinder 16 is fixedly disposed on the lifting slider 6. During the upward movement of the carrying box 7, the first fixed column 17 and the second fixed column 16 rise synchronously. When the first sliding cylinder 14 contacts the top of the L-shaped chute 9, the vertical displacement is converted into a horizontal displacement. The first sliding cylinder 14 causes the first fixed column 17 to act on the carrying box 7 through the reversing plate 15, causing the carrying box 7 to rotate on the second fixed column 16. The first drive motor 5 drives the first fixed column 17 to continue to rise, and the rotation angle of the carrying box 7 increases. The horizontal position of the carrying box 7 rotates to a vertical position, so that the construction waste in the carrying box 7 is poured into the crushing box 2.

[0051] like Figure 1 As shown, the top of the crushing box 2 is provided with a guide channel 37. The guide channel 37 guides the dumped construction waste into the crushing box 2 and guides the construction waste dumped from the carrying box 7, so that the construction waste is poured into the crushing box 2 in a better manner.

[0052] like Figure 6 As shown, the splash-proof assembly includes a partition plate 3, which is symmetrically arranged on the top of the crushing chamber 2. The partition plate 3 is rotatably disposed inside the crushing chamber 2. A guide rod 20 is fixedly disposed at the bottom of the partition plate 3, and the guide rod 20 is slidably disposed in a guide cylinder 18. A return spring 19 is disposed inside the guide cylinder 18, and the return spring 19 is shown to be in a compressed state. The guide cylinder 18 is fixedly disposed on the inner wall of the crushing chamber 2. When construction waste falls onto the partition plate 3, the gravity of the construction waste compresses and contracts the return spring 19, causing the partition plate 3 to rotate downward to create a feed inlet. The construction waste enters the crushing chamber 2 through the feed inlet. When there is no construction waste on the partition plate 3, the return spring 19 rebounds, causing the partition plate 3 to seal the top of the crushing chamber 2. During the crushing process, not only are flying debris prevented, but also dust is prevented from flying.

[0053] like Figure 1 , Figure 7 and Figure 9 As shown, one end of the crushing roller 21 is coaxially connected to a first support rod 27, and the other end is coaxially connected to a second support rod 28. The first support rod 27 passes through a first sliding groove 35 and is rotatably mounted on a first slider 12. A second drive motor 10 and a third drive motor 31 are respectively fixedly mounted on the two first sliders 12. The output ends of the second drive motor 10 and the third drive motor 31 are coaxially connected to the first support rod 27. The output ends of the second drive motor 10 and the third drive motor 31 rotate relative to each other, driving the crushing roller 21 to rotate relative to each other, thus better crushing the construction waste.

[0054] like Figure 1 , Figure 8 and Figure 10 As shown, the first slider 12 is threadedly connected to the first screw 30, which is rotatably mounted on the limiting block 13. A drive unit is coaxially connected to the first screw 30, driving the first screw 30 to rotate. The limiting block 13 is fixedly mounted on the outer wall of the crushing chamber 2. The second support rod 28 is rotatably mounted on the second slider 29, which is slidably mounted within the second sliding groove 36. The first screw 30 has a bidirectional thread. The drive unit drives the first screw 30 to rotate, causing the two first sliders 12 to slide relative to each other, which in turn causes the crushing rollers 21 to slide relative to each other within the crushing chamber 2. This adjusts the distance between the two crushing rollers 21, controlling the size of the crushed construction waste and improving the usability of the device.

[0055] like Figure 1As shown, the drive unit includes a fourth drive motor 11, which is fixedly mounted on a limiting block 13. The output end of the fourth drive motor 11 passes through the limiting block 13 and is coaxially connected to the first screw 30. The fourth drive motor 11 drives the first screw 30 to rotate. The first screw 30 is provided with a bidirectional thread. The first screw 30 drives the crushing rollers 21 to slide relative to each other in the crushing box 2 through the first slider 12, thereby adjusting the distance between the two crushing rollers 21 and controlling the size of the crushed construction waste, thus improving the usability of the device.

[0056] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.
