Description

Technical Field

[0001] This utility model relates to the technical field of construction waste recycling equipment, specifically a classification and screening device for construction waste recycling and processing. Background Technology

[0002] Construction waste refers to various discarded materials generated during building construction, demolition, and renovation. These wastes are extremely complex in composition, typically including concrete, bricks, wood, metal, glass, plastics, and other impurities. Against the backdrop of accelerating global urbanization, the amount of construction waste generated is increasing year by year, placing enormous pressure on the environment and demanding higher standards for waste management systems.

[0003] In response to increasingly severe environmental pollution and the dwindling natural resources, countries are placing greater emphasis on the recycling of construction waste. Effective waste recycling can not only significantly reduce landfill usage and lower the risk of soil and water pollution, but also achieve substantial economic benefits through resource reuse. However, the mixed nature of different materials in construction waste presents numerous challenges to the separation and recycling process.

[0004] Currently, construction waste treatment typically begins with preliminary crushing, a process that reduces waste volume, facilitating transportation and subsequent processing. However, even after crushing, metallic and non-metallic materials remain mixed together, reducing overall recycling efficiency. Metallic materials, in particular, are difficult to separate effectively using traditional screening methods due to their irregular shapes and small size after crushing.

[0005] Traditional screening methods largely rely on physical sieves for separation. However, due to the diverse shapes and sizes of construction waste, sieves alone cannot effectively separate metals from non-metals. This limitation leads to low metal recovery rates, significant resource waste, and fails to fully realize the potential for material reuse. Therefore, we propose a classification and screening device for construction waste recycling. Utility Model Content

[0006] The purpose of this invention is to provide a sorting and screening device for the recycling and processing of construction waste, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A sorting and screening device for construction waste recycling includes a frame-shaped support. First support blocks are located on the front and rear sides of the inner wall of the frame-shaped support, near the left side. Second support blocks are located on the front and rear sides of the inner wall of the frame-shaped support, near the right side. Springs are located at the top of the two first support blocks and the two second support blocks. The tops of the four springs are connected to a screening trough plate. A vibration motor is located at the bottom of the screening trough plate, near the left side. The vibration motor, in conjunction with the four springs, causes the screening trough plate to vibrate, facilitating the movement of crushed solid construction waste to the lower right within the screening trough plate. An electromagnet suction plate is embedded at the bottom of the inner wall of the screening trough plate. Both the vibration motor and the electromagnet suction plate are powered by an external power source. When energized, the electromagnet suction plate generates suction, which can attract and hold metal from the crushed solid waste falling from the screening trough plate. Under the action of the vibration motor, non-metallic waste can continue to fall, thereby achieving the separation of metallic and non-metallic waste.

[0009] A guide cylinder is rotatably connected between the front and rear sides of the inner wall of the frame-shaped support, near the right side. The upper and lower sides of the guide cylinder are open. The input end of the guide cylinder is located directly below the discharge port on the right side of the screening trough plate. An angle adjustment component is provided on the right side of the bottom of the frame-shaped support to adjust the position of the guide cylinder. The angle of the guide cylinder can be adjusted so that the output end of the guide cylinder can be located above the first discharge trough plate and the second discharge trough plate respectively. Two first fixed side plates are provided at the bottom of the frame-shaped support, near the right side. A first discharge trough plate and a second discharge trough plate are provided between the two first fixed side plates, near the bottom. The first discharge trough plate is used to output non-metallic waste, and the second discharge trough plate is used to output metallic waste.

[0010] Preferably, the frame bracket has support frames on both the left and right sides of its bottom, and the support frames are of H-shaped structure to provide stable support for the entire device.

[0011] Preferably, a fixed top plate is provided on the top left side of the inner wall of the screening tank plate, and a feed hopper is provided through the top of the fixed top plate. The crushed construction waste is fed into the screening tank plate to start the separation and screening process.

[0012] Preferably, the right side of the screening trough is inclined downwards, and a guide plate is provided at the opening on the right side of the screening trough. The guide plate has an inverted V-shaped structure to ensure that all waste material output from the screening trough enters the guide cylinder.

[0013] Preferably, a first U-shaped seat is provided in the middle of the upper right side of the guide cylinder, and two second U-shaped seats are provided in the upper right side of the guide cylinder in a symmetrical arrangement. Both second U-shaped seats are rotatably connected to a positioning rod for use with the angle adjustment component.

[0014] Preferably, the angle adjustment component includes a second fixed side plate fixedly connected to the bottom of the frame bracket. A third U-shaped seat is provided on the left side of the second fixed side plate near the bottom center. A hydraulic cylinder is rotatably connected to the third U-shaped seat. The hydraulic cylinder is connected to an external hydraulic drive system. The end of the movable rod of the hydraulic cylinder is rotatably connected to the first U-shaped seat. The hydraulic cylinder drives the guide cylinder to rotate, thereby realizing the angle adjustment. When the electromagnet suction plate is energized to attract metal waste, the movable rod of the hydraulic cylinder is in a fully retracted state. When all the non-metallic waste in the screening trough is output, the movable rod of the hydraulic cylinder is fully extended, so that the output end of the guide cylinder is above the second discharge trough. At this time, the electromagnet suction plate is de-energized. Under the action of the vibration motor, the metal waste in the screening trough can fall downward into the guide cylinder and be guided by the guide cylinder to the second discharge trough for output.

[0015] Preferably, two fourth U-shaped seats are provided on the left side of the second fixed side plate near the bottom, arranged symmetrically front to back. Both fourth U-shaped seats are rotatably connected to a circular tube, and the two positioning rods are slidably connected inside the two circular tubes, thereby improving the stability of the angle adjustment component adjusting the guide cylinder.

[0016] Preferably, the second discharge trough plate and the first discharge trough plate are arranged symmetrically from left to right, with the first discharge trough plate located to the right of the second discharge trough plate. When the movable rod of the hydraulic cylinder is fully extended, the output end of the guide cylinder is located above the second discharge trough plate. When the movable rod of the hydraulic cylinder is fully retracted, the output end of the guide cylinder is located above the first discharge trough plate, ensuring that the guide cylinder can sort and output metal waste and non-metal waste.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This construction waste recycling and sorting device, by installing an electromagnet suction plate in the screening tank and combining it with the action of a vibrating motor, can effectively adsorb and separate metal substances. This design significantly improves the accuracy and efficiency of metal separation and solves the problem that traditional screen methods cannot effectively separate metals and non-metals.

[0019] 2. The sorting and screening device for recycling and processing construction waste has an angle adjustment component that allows the guide cylinder to be flexibly adjusted in position, ensuring that metal and non-metal waste are accurately guided into the corresponding second discharge trough and first discharge trough. This design improves the flexibility and accuracy of the device operation. Attached Figure Description

[0030] Please see Figures 1-7 This utility model provides a technical solution:

[0031] The sorting and screening device for construction waste recycling includes a frame support 1. First support blocks 10 are provided on the front and rear sides of the inner wall of the frame support 1, near the left side. Second support blocks 11 are provided on the front and rear sides of the inner wall of the frame support 1, near the right side. Springs 2 are provided at the top of each of the two first support blocks 10 and the two second support blocks 11. The tops of the four springs 2 are connected to a screening trough 3. A vibration motor 9 is provided at the bottom of the screening trough 3, near the left side. The vibration motor 9, in conjunction with the four springs 2, can cause the screening trough 3 to vibrate, which facilitates the movement of crushed solid construction waste to the lower right within the screening trough 3. An electromagnet suction plate 4 is embedded at the bottom of the inner wall of the screening trough 3. Both the vibration motor 9 and the electromagnet suction plate 4 are powered by an external power source. When the electromagnet suction plate 4 is energized, it generates suction, which can attract metal from the crushed solid waste falling from the screening trough 3. Under the action of the vibration motor 9, non-metallic waste can continue to fall, thereby achieving the separation of metallic and non-metallic waste.

[0032] A guide cylinder 5 is rotatably connected between the front and rear sides of the inner wall of the frame bracket 1 and near the right side. The upper and lower sides of the guide cylinder 5 are open. The input end of the guide cylinder 5 is located directly below the discharge port on the right side of the screening trough plate 3. An angle adjustment component 6 is provided on the right side of the bottom of the frame bracket 1 to adjust the position of the guide cylinder 5. The angle of the guide cylinder 5 can be adjusted so that the output end of the guide cylinder 5 can be located above the first discharge trough plate 7 and the second discharge trough plate 8 respectively. Two first fixed side plates 13 are provided at the bottom of the frame bracket 1 and near the right side. The first discharge trough plate 7 and the second discharge trough plate 8 are provided between the two first fixed side plates 13 and near the bottom. The first discharge trough plate 7 is used to output non-metallic waste, and the second discharge trough plate 8 is used to output metallic waste.

[0033] In this embodiment, support frames 12 are provided on both the left and right sides of the bottom of the frame bracket 1. The support frames 12 have an H-shaped structure and provide stable support for the entire device.

[0034] Specifically, a fixed top plate 30 is provided on the top left side of the inner wall of the screening tank plate 3, and a feed hopper 31 is provided through the top of the fixed top plate 30. The crushed construction waste is fed into the screening tank plate 3 to start the separation and screening process.

[0035] Furthermore, the right side of the screening trough plate 3 is inclined downwards, and a guide plate 32 is provided at the opening on the right side of the screening trough plate 3. The guide plate 32 has an inverted V-shaped structure to ensure that all the waste material output from the screening trough plate 3 enters the guide cylinder 5.

[0036] Furthermore, a first U-shaped seat 50 is provided in the middle of the upper right side of the guide cylinder 5, and two second U-shaped seats 51 are provided in the upper right side of the guide cylinder 5 in a symmetrical arrangement. Both second U-shaped seats 51 are rotatably connected to a positioning rod 52 for use by the angle adjustment component 6.

[0037] Furthermore, the angle adjustment component 6 includes a second fixed side plate 60 fixedly connected to the bottom of the frame bracket 1. A third U-shaped seat 61 is provided on the left side of the second fixed side plate 60 near the bottom center. A hydraulic cylinder 62 is rotatably connected to the third U-shaped seat 61. The hydraulic cylinder 62 is connected to an external hydraulic drive system. The end of the movable rod of the hydraulic cylinder 62 is rotatably connected to the first U-shaped seat 50. The hydraulic cylinder 62 drives the guide cylinder 5 to rotate, thereby realizing the angle adjustment. When the electromagnet suction plate 4 is energized to attract metal waste, the movable rod of the hydraulic cylinder 62 is in a fully retracted state. When all the non-metallic waste in the screening trough 3 is output, the movable rod of the hydraulic cylinder 62 is fully extended, so that the output end of the guide cylinder 5 is above the second discharge trough 8. At this time, the electromagnet suction plate 4 is de-energized. Under the action of the vibration motor 9, the metal waste in the screening trough 3 can fall down into the guide cylinder 5 and be guided by the guide cylinder 5 to the second discharge trough 8 for output.

[0038] Furthermore, two fourth U-shaped seats 63 are provided on the left side of the second fixed side plate 60 near the bottom, arranged symmetrically front to back. Both fourth U-shaped seats 63 are rotatably connected to circular tubes 64, and two positioning rods 52 are slidably connected to the two circular tubes 64 respectively, thereby improving the stability of the angle adjusting component 6 adjusting the guide cylinder 5.

[0039] Furthermore, the second discharge trough plate 8 and the first discharge trough plate 7 are arranged symmetrically from left to right, with the first discharge trough plate 7 located to the right of the second discharge trough plate 8. When the movable rod of the hydraulic cylinder 62 is fully extended, the output end of the guide cylinder 5 is located above the second discharge trough plate 8. When the movable rod of the hydraulic cylinder 62 is fully retracted, the output end of the guide cylinder 5 is located above the first discharge trough plate 7, ensuring that the guide cylinder 5 can sort and output metal waste and non-metal waste.

[0040] In this embodiment, the classification and screening device for construction waste recycling and processing is used by starting the vibration motor 9 and simultaneously activating the electromagnet suction plate 4. Then, the crushed construction waste is fed into the screening trough 3 through the feed hopper 31 on the fixed top plate 30, ensuring uniform waste input to prevent blockage. The vibration motor 9 vibrates the screening trough 3 and promotes the waste to move downwards and to the right. The electromagnet suction plate 4 attracts falling metal waste within the screening trough 3. Under vibration, non-metallic waste continues to move downwards. The inclined design of the screening trough 3 facilitates the natural fall of non-metallic waste, while the electromagnet suction plate 4 attracts metallic substances to prevent them from mixing with non-metallic waste. The waste is then guided by the guide plate 32... With its inverted V-shaped structure, waste is guided into the guide cylinder 5, which in turn guides the non-metallic waste into the first discharge trough 7 and outputs it. After all the non-metallic waste in the screening trough 3 has been output, the movable rod of the hydraulic cylinder 62 extends fully, positioning the output end of the guide cylinder 5 above the second discharge trough 8. At this point, the electromagnet suction plate 4 is de-energized, and under the action of the vibrating motor 9, the metallic waste in the screening trough 3 can fall downwards into the guide cylinder 5 and be guided by the guide cylinder 5 to the second discharge trough 8 for output. Through these operating steps, the device can efficiently separate and process construction waste, improve material recycling efficiency, reduce resource waste, and play a positive role in environmental protection.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
