Description

Technical Field

[0001] This invention relates to the field of construction waste treatment equipment technology, and more specifically, to construction waste treatment equipment. Background Technology

[0002] Construction waste treatment equipment is a core component in the field of construction solid waste resource utilization, widely used in demolition sites, renovation sites of old projects, and waste material processing for new construction projects. Its main function is to crush and reduce the volume of mixed construction waste such as concrete blocks, brick fragments, metal components, and plastic waste, separating recyclable resources (such as metals and plastics). This reduces land occupation and environmental pollution caused by open dumping or landfilling of construction waste, and provides raw materials for the production of recycled building materials (such as recycled aggregates and recycled plastic pellets). It is a key piece of equipment for promoting the green circular economy development of the construction industry and reducing solid waste treatment costs.

[0003] However, traditional construction waste disposal methods have significant limitations and cannot meet the demands for efficient and economical processing. Existing processes often employ a segmented "crushing + sorting" approach: large pieces of construction waste are first crushed into smaller particles using single crushing equipment such as jaw crushers or impact crushers, and then metals and plastics are sorted separately using specialized equipment like magnetic separators or eddy current separators, or by manual sorting. This approach has significant problems: machine sorting requires additional investment in multiple specialized devices, significantly increasing purchase and maintenance costs, and the combination of multiple devices occupies more space, placing stringent requirements on site planning; manual sorting suffers from high labor intensity and low sorting efficiency, and is prone to missing recyclable resources due to human error, wasting resources and being unsuitable for large-scale construction waste processing. Therefore, there is an urgent need to develop construction waste processing equipment that integrates crushing and sorting functions to overcome these bottlenecks. Summary of the Invention

The crushing and driving mechanisms work together to crush construction waste twice during operation. The crushed waste is then conveyed to the left by the screening module, separating magnetic metals, plastics, and lighter materials, while non-magnetic metals and other construction waste are conveyed to the right.

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0021] In this invention, unless otherwise stated, the directional terms such as "up" and "down" generally refer to the directions shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" generally refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0022] Please see Figures 1-8A construction waste treatment device includes a housing 1, which provides a supporting frame for the entire device. A feeding ramp 33 fixedly connected to the lower side of the housing 1 has four partitions in the middle for classifying and receiving different types of sorted waste. A crushing box 2 fixedly connected to the upper side of the housing 1 holds the construction waste and provides crushing space. A fixed jaw 3 is fixed to the inner left side wall of the crushing box 2. A movable jaw 4 is rotatably connected to the inner side wall of the crushing box 2 via a rotating shaft. The output shaft of a bidirectional motor 5 is connected to the outer surface of a crankshaft 6 via a first pulley group 9. One end of a first connecting rod 8 rotatably connected to the outer surface of the middle part of the crankshaft 6 is rotatably connected to the right side of the movable jaw 4 via a hinge block. The bidirectional motor 5 drives the crankshaft 6 to rotate, and the crankshaft 6 drives the movable jaw 4 to reciprocate via the first connecting rod 8. The rotating mechanism, in conjunction with the fixed jaw 3, crushes large pieces of waste. The flywheel 7, fixed at both ends of the crankshaft 6, stores inertial energy to enhance the power of the movable jaw 4, crushing large pieces of waste such as concrete and bricks, thus improving the crushing efficiency. The crushing roller 11 is rotatably connected to the inner wall of the crushing box 2 via the first rotating shaft 10. One end of the first rotating shaft 10 passes through the front of the crushing box 2 and is fixedly connected to two gears 12 that mesh with each other. One end of the output shaft of the bidirectional motor 5 is connected to the front end of the right first rotating shaft 10 via the second pulley group 13. The bidirectional motor 5 drives the right first rotating shaft 10 to rotate via the pulley group. The meshing of the two gears 12 causes the two crushing rollers 11 to rotate synchronously in opposite directions, performing secondary crushing of the crushed waste to refine the particle size and meet the subsequent sorting requirements.

[0023] The first rotating roller 17 of the screening module 16 is rotatably connected to the left side of the inner wall of the equipment housing 1, and the second rotating roller 18 is rotatably connected to the right side of the inner wall of the equipment housing 1. The front end of the first rotating shaft 10 on the left is connected to the front end of the first rotating roller 17 through the third pulley group 27, and the front end of the first rotating shaft 10 on the right is connected to the front end of the second rotating roller 18 through the fourth pulley group 28. The outer surface of the second rotating roller 18 is fixedly connected to the bearing 19 and has a toothed groove 20. The left side of the magnetic conveyor belt 25 is connected to the toothed groove 20 on the outer surface of the first rotating roller 17, and the right side is connected to the bearing 19 on the outer surface of the second rotating roller 18. The left side of the non-magnetic conveyor belt 26 is connected to the bearing 19 on the outer surface of the first rotating roller 17, and the right side is connected to the toothed groove 20 on the outer surface of the second rotating roller 18. The first rotating shaft 10 drives the rotating roller to rotate through the pulley group. The bearing 19 and the toothed groove 20 cooperate to make the magnetic conveyor belt 25 rotate counterclockwise and the non-magnetic conveyor belt 26 rotate clockwise, respectively conveying magnetic and non-magnetic waste, realizing the initial sorting and conveying of waste, and avoiding the mixing of different types of waste.

[0024] The rear end of the limiting inner sleeve 21 is fixed to the inner wall of the equipment housing 1. The output shaft of the motor 22, which is fixedly connected to the inner wall, is fixedly connected to one end of the sorting roller 23. The outer surface of the sorting roller 23 is fixedly connected to the multi-pole alternating magnetic block 24. The principle is that the second motor 22 drives the sorting roller 23 to rotate, and the multi-pole alternating magnetic block 24 generates an alternating magnetic field. Non-magnetic metals (such as aluminum sheets) enter the magnetic field and generate eddy currents. They are pushed away from the non-magnetic conveyor belt 26 and thrown towards the arc-shaped separator plate 29 (fixedly connected to the right side of the screening module 16 on the inner wall of the equipment housing 1), thus accurately separating the non-magnetic metals.

[0025] A separation plate 34 is fixedly connected to the lower left side of the screening module 16 on the inner wall of the equipment shell 1. Magnetic metals (such as steel bar fragments) conveyed by the magnetic conveyor belt 25 are stripped off by the separation plate 34 and fall into the left channel of the feeding inclined plate 33 for separate collection. A chain conveyor belt 39 is installed at an angle on the inner wall of the water separation tank 38 fixedly connected to the left side of the equipment shell 1. The lower end of the permeable net 37 is located inside the water separation tank 38. Light waste (such as plastic) falls into the water separation tank 38 and is conveyed to the left end for recycling by the chain conveyor belt 39. The silt in the water is discharged through the sewage pipe 40 fixedly connected to the lower front side of the water separation tank 38, realizing the recycling of light waste and the cleaning of silt.

[0026] The inner wall of the equipment casing 1 is fixedly connected to the buffer rubber plate 15 below the crushing box 2. When the crushed waste falls, it contacts the buffer rubber plate 15 to reduce the impact speed, prevent the waste from directly hitting the screening module 16, extend the service life of the screening module 16, and reduce the frequency of equipment maintenance.

[0027] Please see Figures 1-4 The first cross-flow fan 14 is inclinedly installed on the upper right side of the screening module 16 on the inner wall of the equipment shell 1. After starting, it generates directional airflow. The airflow direction is consistent with the counterclockwise conveying direction of the magnetic conveyor belt 25. It can push the light waste with low density (such as plastic and paper scraps) to the left, separate the light waste in advance, reduce the sorting burden of the subsequent screening module 16, and improve the overall sorting efficiency.

[0028] The inner wall of the equipment casing 1 is fixedly connected to the second cross-flow fan 35 on the left side of the separation plate 34, and a protective net 36 is fixedly connected above it. The air outlet of the second cross-flow fan 35 faces upward, which can blow up the light waste stuck in the gap between the magnetic conveyor belt 25 and the non-magnetic conveyor belt 26, and prevent the waste from clogging the conveyor belt. The protective net 36 can block construction waste particles from entering the fan, prevent blade wear, and further improve the separation rate of light waste.

[0029] The outer surface of the equipment shell 1 is rotatably connected to the air-permeable mesh 37. The lower end of the air-permeable mesh 37 extends into the water separation tank 38, which not only ensures that the airflow generated by the first cross-flow fan 14 and the second cross-flow fan 35 is discharged smoothly, but also prevents garbage from splashing to the outside of the equipment. The effect is to maintain the airflow circulation inside the equipment and prevent garbage leakage from polluting the environment. Moreover, the airflow guiding structure is integrated with the screening module 16, which does not require additional space. The overall size of the equipment is smaller than that of traditional equipment, making it suitable for narrow construction site scenarios.

[0030] Please see Figures 1-4 The lower side of the arc-shaped partition plate 29 is rotatably connected to the screen 30. The upper surface of the screen 30 has fine filter holes on the right side and coarse filter holes on the left side. Non-magnetic construction waste such as concrete and bricks is guided to the surface of the screen 30 through the arc-shaped partition plate 29. The fine filter holes can filter small particles, and the coarse filter holes can filter medium particles. Large particles that do not pass through the filter holes slide off from the left end of the screen 30, realizing three-stage screening of construction waste particles and meeting the different raw material requirements of recycled mortar (fine particles) and recycled aggregate (medium particles).

[0031] A connecting rod 31 is fixedly connected to the front left side of the screen 30. A groove adapted to the connecting rod 31 is opened on the outer surface of the equipment shell 1. The outer surface of the connecting rod 31 is slidably connected to the inner wall of the groove. One end of the second connecting rod 32, which is rotatably connected to the outer surface of the front end of the connecting rod 31, is rotatably connected to the front end of the first rotating shaft 10 through an eccentric rotating shaft. When the first rotating shaft 10 rotates, the eccentric rotating shaft at its front end drives the second connecting rod 32 to swing back and forth. The second connecting rod 32 pulls the connecting rod 31 to slide up and down along the groove, thereby driving the screen 30 to shake up and down around the rotating shaft on the lower side of the arc-shaped partition plate 29, avoiding the blockage of the filter holes by construction waste particles and making the screen 30 feed smoothly. Moreover, the first rotating shaft 10 of the crushing mechanism is directly reused as the power source, eliminating the need for an additional shaking motor and reducing the equipment manufacturing cost.

[0032] The lower part of the feeding inclined plate 33, which is fixedly connected to the outer shell 1, is equipped with four partitions. The four partitions correspond to the fine filter area, coarse filter area, large particle sliding area and magnetic metal falling area of ​​the screen 30, respectively, forming four independent feeding channels. This enables the classified collection of materials of different types and particle sizes, avoids mixing, improves subsequent processing efficiency, and increases the resource utilization rate of construction waste compared to non-grading screening.

[0033] In summary, when the entire equipment is in use: construction waste is introduced into the equipment from the top of the crushing box 2. When the bidirectional motor 5 is working, it drives the crankshaft 6 to rotate through the first pulley group 9. When the crankshaft 6 rotates, it drives the movable jaw 4 to rotate back and forth through the first connecting rod 8, crushing large pieces of construction waste that enter between the fixed jaw 3 and the movable jaw 4. The inertial energy stored by the flywheel 7 facilitates the lifting of the movable jaw 4. When the bidirectional motor 5 is working, it also drives the crushing roller 11 to rotate through the transmission action of the second pulley group 13. Through the transmission action of the two gears 12, the two crushing rollers 11 are driven to rotate in opposite directions, thereby crushing the construction waste that has passed between the two crushing rollers 11 again. Then the crushed construction waste falls onto the upper surface of the screening module 16. The buffer rubber plate 15 provides cushioning during the falling process of the crushed construction waste. The construction waste lands on the upper surface of the magnetic conveyor belt 25 and the non-magnetic conveyor belt 26. The first cross-flow fan 14 blows the lightweight plastic construction waste to the left. Through the third pulley group 27, the first rotating shaft 10 can drive the first rotating roller 17 to rotate. The first rotating roller 17 drives the non-magnetic conveyor belt 26 to rotate through the toothed grooves 20 on its outer surface. The other end of the non-magnetic conveyor belt 26 rotates with the outer surface of the second rotating roller 18 through the bearing 19, causing the non-magnetic conveyor belt 26 to rotate clockwise, conveying the non-magnetic waste to the right. Similarly, the transmission of the fourth pulley group 28 drives the second rotating roller 18 to rotate counterclockwise, thereby causing the magnetic conveyor belt 25 to rotate counterclockwise. The magnetic waste is conveyed to the left by the counter-clockwise rotation and falls onto the upper surface of the magnetic conveyor belt 25. The raised areas on the outer surface of the magnetic conveyor belt 25 cause the non-magnetic construction waste to gradually move forward and backward during transport, falling into the grooves of the non-magnetic conveyor belt 26. Meanwhile, the magnetic metal within the non-magnetic conveyor belt 26 is attracted to the upper surface of the magnetic conveyor belt 25 and moves to the left along with it. After reaching the left end of the screening module 16, the magnetic waste is scraped off and falls into the discharge ramp 33, exiting from the left side of the ramp 33. The second cross-flow fan 35 blows air upwards, working in conjunction with the first cross-flow fan 14 to blow the lightweight waste to the upper left, causing it to fall into the water separation tank 38. The permeable mesh 37 allows for outward ventilation while preventing waste from flying out. At this time, lightweight waste falls into the water in the water separation tank 38 and is discharged from the left end of the lightweight waste bin by the chain conveyor belt 39. The mud and other impurities in the water separation tank 38 can be discharged and cleaned out through the drain pipe 40 by opening the valve 41. Non-magnetic waste is transported to the right by the non-magnetic conveyor belt 26. When it passes above the second rotating roller 18, the motor 22 drives the sorting roller 23 to rotate. Through the setting of the multi-pole alternating magnetic blocks 24, an alternating magnetic field is generated around it. When non-magnetic metal enters the magnetic field, it generates induced eddy currents. Since the non-magnetic metal has a relative velocity with the magnetic field, it exerts a pushing force on the metal pieces and blocks that generate eddy currents, pushing them away from the upper surface of the non-magnetic conveyor belt 26 and throwing them to the right side of the arc-shaped partition plate 29. Finally, it is discharged from the right side of the discharge inclined plate 33.After being crushed, concrete and brick debris falls directly from the right end of the screening module 16. Guided by the arc-shaped partition plate 29, it lands on the upper surface of the screen 30. When the crushing roller 11 rotates, the eccentric shaft at the front end of the first rotating shaft 10 and the transmission action of the second connecting rod 32 drive the screen 30 to vibrate up and down, facilitating the falling of debris from the upper surface of the screen 30. Furthermore, the fine and coarse filter holes on the upper surface of the screen 30 can separate the debris into different sizes. Finally, the concrete and brick particles are separated into large, medium, and small grades and discharged through the feed inclined plate 33.

For all the fixed connections mentioned above, welding is preferred.
