Description

Technical Field

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

[0002] Construction waste recycling is an important measure for reusing waste generated during construction and demolition. Construction waste has a complex composition, including concrete, bricks, wood, plastics, and metals. Through effective recycling, concrete and bricks can be crushed and made into recycled aggregates for road base and building subbase. Wood can be processed into recycled boards or biomass fuel. Metals can be sorted and then smelted. Plastics can be recycled and granulated for reuse. This not only reduces the amount of waste going to landfills and alleviates pressure on land resources, but also reduces the exploitation of primary resources, saves energy, reduces environmental pollution, and achieves the circular use of resources. It is of great significance to promoting the sustainable development of the construction industry.

[0003] Existing technologies, such as the utility model with publication number CN213256235U, relate to the field of construction equipment, specifically a construction waste recycling device for construction. This device includes a main body box with a detachable support block at its bottom. Inside the main body box is a recycling bin and a detachable filter screen. A connecting block is detachably installed on one side of the filter screen. An inlet is located at the top of the main body box, and a motor is located on one side of the inlet. This utility model, by using a filter screen positioned above the recycling bin and angled, not only filters construction waste but also expands the filtration area, improving filtration efficiency and quality. Furthermore, the bottom of the recycling bin includes a sliding seat, pulleys, a first toothed plate, a second toothed plate, and toothed blocks, allowing workers to adjust the position of the recycling bin, thus improving the overall practicality of the device.

[0004] However, construction waste is complex, containing a variety of materials such as concrete, bricks, wood, plastics, and metals. Currently, it is difficult to effectively classify these materials, resulting in poor purity of the recycled materials. For example, metals may contain other impurities, affecting smelting quality, and wood may contain bricks, which is not conducive to reprocessing and utilization. Moreover, it will reduce the efficiency of resource reuse and increase processing costs, as further separation and purification are required. Utility Model Content

[0005] The purpose of this invention is to address the problem in the existing technology that construction waste has a complex composition, encompassing various materials such as concrete, bricks, wood, plastics, and metals, making it difficult to effectively classify these materials and resulting in poor purity of the recycled materials. Therefore, this invention proposes a construction waste recycling device for construction.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a construction waste recycling device for building construction, comprising a box and a sorting device. A hopper is fixedly installed on the upper surface of the box, and the sorting device is installed in the inner wall of the box. The sorting device includes a magnetic suction plate, which is fixedly connected to the inner wall of the box. Multiple filter holes are opened on the surface of the magnetic suction plate. The interior of the box is hollow. A dust inlet is opened on the lower surface of the box, and a round cover is threadedly connected to the surface of the dust inlet. A sorting box is fixedly connected to one side of the box, and a fan is fixedly installed on one side of the sorting box. A servo motor is fixedly installed on the surface of the fan. A collection box is provided on the lower surface of the sorting box. A pushing component is provided at the end of the box near the magnetic suction plate. By setting up the sorting device, different types of construction waste can be separated, allowing various materials to be better recycled and reused. Compared with traditional manual or inefficient sorting methods, this greatly improves the processing efficiency of construction waste and can quickly complete the sorting of large amounts of construction waste, meeting the needs of actual engineering projects.

[0007] Preferably, the sorting box has an air inlet on the side near the fan, and a dust filter is fixedly connected to the inner wall of the air inlet on one side of the sorting box. By setting up the sorting box, the sorting box provides a centralized processing space for construction waste. When large bricks roll into the sorting box from the inclined magnetic plate, the sorting box can gather these pre-screened materials together, laying the foundation for subsequent more detailed sorting operations based on different material characteristics, and avoiding the materials being scattered and difficult to process uniformly.

[0008] Preferably, a discharge pipe is fixedly connected to the end of the sorting box away from the fan. The discharge pipe is connected to the sorting box. By setting up a fan, after the construction waste enters the sorting box, the fan is started and drives the airflow to blow towards the discharge pipe. Because lightweight materials such as plastics are light, they will enter the discharge pipe along with the airflow and be discharged, thus achieving separation from the construction waste.

[0009] Preferably, a magnet is fixedly connected to the lower surface of the sorting box, and a slot is provided on the side of the collection box near the magnet. The magnet is inserted into the slot on one side of the collection box and magnetically connected. By setting the magnet, it is easy to fix the collection box on the sorting box, which increases the stability of the equipment and reduces the difficulty of operating the equipment.

[0010] Preferably, a pull rod is fixedly connected to one end of the collection box, and the magnetic suction plate is set at an angle. By setting the magnetic suction plate, the magnetic suction plate has magnetism and can attract iron building materials in the construction waste to its surface. In this way, the iron materials are separated from the mixed construction waste, which provides convenience for the separate recycling of iron materials in the future.

[0011] Preferably, the pushing assembly includes a chute formed on the surface of the box. A sliding rod is slidably connected to the inner wall of the chute, and a pushing plate is fixedly connected to the surface of the sliding rod. By setting up the pushing assembly, the pushing assembly moves the sliding rod along the surface of the magnetic plate by pulling the handle, pushing the adsorbed iron waste out of the magnetic plate. This operation allows the iron material to be smoothly removed from the magnetic plate, making it easy to recycle. It avoids the problem that the iron material cannot be effectively recycled due to being too firmly adsorbed, and improves the recycling efficiency of the iron material.

[0012] Preferably, a handle is fixedly connected to the end of the slide bar away from the pusher plate. The pusher plate is in contact with the magnetic suction plate. The pusher plate is made of plastic. By setting the pusher plate, the pusher plate can move smoothly along the surface of the magnetic suction plate under the action of the slide bar, and gradually push out the iron waste adsorbed on it. This operation allows the iron material to be smoothly removed from the magnetic suction plate, realizing the efficient recycling of iron material.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In this invention, a sorting device is installed. During use, recycled construction waste is poured into the hopper and passes through to the magnetic suction plate. Dust in the waste passes through the magnetic suction plate and falls into the box, while ferrous building materials are attracted to it. Because the magnetic suction plate is tilted, large bricks roll down and enter the sorting box. A servo motor is activated, driving a fan to blow air towards the discharge pipe. As the construction waste falls into the sorting box, lightweight waste such as plastics is carried by the airflow into the discharge pipe and discharged. Heavier bricks are not affected by the airflow and fall into the collection box. Pulling the lever removes the collection box, and rotating the round cover opens the dust outlet for cleaning. This sorting device separates different types of construction waste, allowing for better recycling and reuse of various materials. Compared to traditional manual or inefficient sorting methods, it significantly improves the efficiency of construction waste processing, enabling the rapid sorting of large quantities of construction waste and meeting practical engineering needs.

[0015] In this invention, by setting up a pushing component, after sorting, pulling the handle causes the sliding rod to slide, and as the sliding rod slides, it causes the pushing plate to move along the surface of the magnetic suction plate, pushing out the adsorbed iron waste from the magnetic suction plate for easy recycling. By setting up the pushing component, after the construction waste is sorted, pulling the handle causes the sliding rod to slide, and the sliding rod in turn causes the pushing plate to move along the surface of the magnetic suction plate, thereby pushing out the iron waste adsorbed on the magnetic suction plate, making the iron waste easy to recycle, reducing the problem of iron waste being difficult to remove from the magnetic suction plate after a long time, and improving the recycling efficiency and ease of operation of iron waste.

[0022] Please see Figures 1-5 This utility model provides a technical solution: a construction waste recycling device for building construction, including a box 1 and a sorting device 3. A hopper 2 is fixedly installed on the upper surface of the box 1, and the sorting device 3 is installed in the inner wall of the box 1.

[0023] In this implementation scheme: the sorting device 3 includes a magnetic suction plate 31, which is fixedly connected to the inner wall of the box 1. The surface of the magnetic suction plate 31 is provided with multiple filter holes. The interior of the box 1 is hollow. The lower surface of the box 1 is provided with a dust inlet 32, and a round cover 33 is threadedly connected to the surface of the dust inlet 32. A sorting box 34 is fixedly connected to one side of the box 1. A fan 312 is fixedly installed on one side of the sorting box 34. A servo motor 36 is fixedly installed on the surface of the fan 312. A collection box 37 is provided on the lower surface of the sorting box 34. A pushing component 39 is provided at one end of the box 1 near the magnetic suction plate 31. By setting up the sorting device 3, different types of construction waste can be separated, so that various materials can be better recycled and reused. Compared with traditional manual or inefficient sorting methods, the processing efficiency of construction waste is greatly improved, and a large amount of construction waste can be sorted quickly to meet the needs of actual engineering.

[0024] Specifically, the sorting box 34 has an air inlet on the side near the fan 312, and a dust filter 38 is fixedly connected to the inner wall of the air inlet on one side of the sorting box 34. By setting up the sorting box 34, the sorting box 34 provides a centralized processing space for construction waste. When large bricks roll down from the inclined magnetic plate 31 into the sorting box 34, the sorting box 34 can gather these pre-screened materials together, laying the foundation for subsequent more detailed sorting operations based on different material characteristics, and avoiding the materials being scattered and difficult to process uniformly.

[0025] Specifically, a discharge pipe 35 is fixedly connected to the end of the sorting bin 34 away from the blower 312. The discharge pipe 35 is connected to the sorting bin 34. By setting up the blower 312, after the construction waste enters the sorting bin 34, the blower 312 is started, driving the airflow to blow towards the discharge pipe 35. Because lightweight materials such as plastics are light, they will enter the discharge pipe 35 along with the airflow and be discharged, thus achieving separation from the construction waste.

[0026] Specifically, a magnet 310 is fixedly connected to the lower surface of the sorting box 34, and a slot is provided on the side of the collection box 37 near the magnet 310. The magnet 310 is inserted into the slot on one side of the collection box 37 and magnetically connected. By setting the magnet 310, it is easy to fix the collection box 37 on the sorting box 34, which increases the stability of the equipment and reduces the difficulty of operating the equipment.

[0027] Specifically, a pull rod 311 is fixedly connected to one end of the collection box 37, and the magnetic plate 31 is set at an angle. By setting the magnetic plate 31, the magnetic plate 31 has magnetism and can attract iron building materials in the construction waste to its surface. In this way, the iron materials are separated from the mixed construction waste, which provides convenience for the separate recycling of iron materials in the future.

[0028] Specifically, the pusher assembly 39 includes a chute 394, which is formed on the surface of the housing 1. A slide rod 392 is slidably connected to the inner wall of the chute 394, and a pusher plate 393 is fixedly connected to the surface of the slide rod 392.

[0029] In this embodiment: by setting up a pushing component 39, the pushing component 39 pulls the handle 391, causing the slide bar 392 to drive the pushing plate 393 to move along the surface of the magnetic suction plate 31, pushing the adsorbed iron waste out of the magnetic suction plate 31. This operation allows the iron material to be smoothly separated from the magnetic suction plate 31, making it easier to recycle. It avoids the problem that the iron material cannot be effectively recycled due to being too firmly adsorbed, and improves the recycling efficiency of the iron material.

[0030] Specifically, a handle 391 is fixedly connected to the end of the slide bar 392 away from the pusher plate 393, the pusher plate 393 is in contact with the magnetic plate 31, and the pusher plate 393 is made of plastic.

[0031] In this embodiment: by setting a pusher plate 393, the pusher plate 393 can move smoothly along the surface of the magnetic suction plate 31 under the drive of the slide rod 392, and gradually push out the iron waste adsorbed on it. This operation allows the iron material to be smoothly removed from the magnetic suction plate 31, and realizes the efficient recycling of iron material.

[0032] Working principle: By setting up a sorting device 3, during use, the recycled construction waste is poured into the hopper 2, passing through the hopper 2 to the magnetic suction plate 31. Dust in the waste passes through the magnetic suction plate 31 and falls into the box 1, while ferrous building materials are attracted to the magnetic suction plate 31. Because the magnetic suction plate 31 is tilted, large bricks roll down and enter the sorting box 34. The servo motor 36 is activated, driving the fan 312 to blow air towards the discharge pipe 35. The construction waste falling into the sorting box 34 is then separated by the airflow. Lightweight waste such as bricks is discharged into the discharge pipe 35 by the airflow. Since bricks are heavier, they are not affected by the airflow and fall into the collection box 37. The collection box 37 can be removed by pulling the lever 311, and the dust port 32 can be opened by rotating the round cover 33 to clean the dust. By setting up the sorting device 3, different types of construction waste can be separated, so that various materials can be better recycled and reused. Compared with the traditional manual or inefficient sorting method, the efficiency of construction waste processing is greatly improved. It can quickly complete the sorting of a large amount of construction waste and meet the actual engineering needs.

[0033] By setting up the pushing component 39, after the sorting is completed, pulling the handle 391 causes the slide bar 392 to slide. As the slide bar 392 slides, it causes the pushing plate 393 to move along the surface of the magnetic plate 31, pushing out the adsorbed iron waste from the magnetic plate 31 for easy recycling. By setting up the pushing component 39, after the construction waste is sorted, pulling the handle 391 causes the slide bar 392 to slide. The slide bar 392 then causes the pushing plate 393 to move along the surface of the magnetic plate 31, thereby pushing out the iron waste adsorbed on the magnetic plate 31. This makes the iron waste easy to recycle, reduces the problem of iron waste being difficult to remove from the magnetic plate 31 after being adsorbed for a long time, and improves the recycling efficiency and ease of operation of iron waste.
