Description

Technical Field

[0001] The invention relates to the technical field of building material recycling, in particular to a processing device for recycling building materials. Background Art

[0002] With the continuous acceleration of urbanization, the construction industry is booming. At the same time, the amount of construction waste is also increasing day by day. The traditional way of treating construction waste has many disadvantages. In terms of waste treatment, most of them used simple landfill or open-air stacking, which not only occupies a lot of precious land resources, but also causes serious pollution to soil and water sources. Construction waste contains various harmful substances, such as heavy metals and chemical additives, which will gradually penetrate into the ground and harm the ecological environment. In addition, construction waste piled in the open air is also easily eroded by wind and rain, resulting in dust pollution, affecting the surrounding air quality and residents' health; There are also shortcomings in the traditional approach to the utilization of recyclable resources in construction waste. For example, metal materials such as steel bars mixed in construction waste have been mainly sorted manually in the past, which is extremely inefficient and difficult to ensure the thoroughness of the sorting. A large amount of valuable metal resources are wasted and not fully recycled, resulting in a huge loss of resources. At the same time, manual sorting requires a lot of manpower costs and has low economic benefits. In terms of dust reduction measures, traditional construction waste treatment sites lack effective dust reduction methods. In the process of handling construction waste, especially during operations such as crushing, a large amount of dust will be generated, seriously affecting the surrounding environment and air quality. Existing dust reduction methods, such as simple watering to reduce dust, have limited effects and cannot meet increasingly stringent environmental protection requirements.

[0003] To sum up, traditional methods of treating construction waste have serious defects in resource recycling and environmental protection. There is an urgent need for a new type of treatment device that can not only efficiently crush construction waste, but also accurately recycle metal materials such as steel bars, while also having effective dust reduction measures to meet the needs of sustainable development of the construction industry.

[0004] After searching, it was found that the prior art publication number is CN111068811A, which discloses an environmentally friendly recycling and utilization equipment for building materials, including a recycling box, a feeding port is provided on the left side of the top of the recycling box, and a debris discharge port is provided at the lower part of the right wall of the recycling box.

The piston rod of the cylinder is fixedly connected to the push plate, and the right side of the push plate is connected to the left end of the sliding rod. The invention is suitable for an environmentally friendly recycling and utilization equipment for building materials. The whole device crushes and preliminarily screens the building materials, so that the crushed garbage such as cement and stones in the building materials can be directly screened and processed for subsequent construction use, thereby improving the utilization rate of building materials and being more energy-saving and environmentally friendly.

A plurality of first connecting columns 22 are fixedly connected to the outer wall of the striking plate 23, and the plurality of first connecting columns 22 are distributed in an array from front to back on the outer wall of the striking plate 23; See also Figure 4 , Figure 8 - Fig.10 The magnetic attraction mechanism 301 includes a plurality of elastic telescopic rods 31, which are fixedly connected to the outer wall of the rotating barrel 18. The plurality of elastic telescopic rods 31 are distributed in a circle on the outer wall of the rotating barrel 18. An abutment ball 32 is movably installed at one end of the elastic telescopic rod 31 away from the rotating barrel 18. The abutment ball 32 is spherical. A metal plate 33 and two ceramic blocks 34 are fixedly connected to one end of the water tank 3 close to the casing 1. The outer walls of the metal plate 33 and the two ceramic blocks 34 abut against adjacent abutment balls 32. The metal plate 33 and the ceramic blocks 34 are in a complete circle. The metal plate 33 is made of copper and has good electrical conductivity and good corrosion resistance and high temperature resistance. Two curved arc bars 17 are also fixedly connected to the inner wall of the casing 1. The curved arc bars 17 are curved. The two curved arc bars 17 are symmetrically distributed front and back in the inner wall of the casing 1. The two curved arc bars 17 are located directly below an adjacent crushing plate 16. An abutment plate 20 is fixedly connected between the bottoms of the two curved bars 17, a dredging pipe 35 and a material guide pipe 36 are fixedly connected at the bottom of the casing 1, the dredging pipe 35 and the material guide pipe 36 are symmetrically distributed at the bottom of the casing 1, a collecting box 14 is fixedly connected to the bottom of the casing 1, the collecting box 14 and the material guide pipe 36 are fixedly connected through a pipeline, a triangular block 42 is also fixedly connected to the bottom end of the inner wall of the casing 1, the triangular block 42 is located on the right side of the material guide pipe 36, and the triangular block 42 is triangular, a plurality of electromagnetic blocks 19 are fixedly connected to the outer wall of the rotating barrel 18, and each electromagnetic block 19 is fixedly connected to the adjacent elastic telescopic rod 31 through an electric wire.

[0023] The working principle of the present invention is: When in use, it is only necessary to place the fragments of construction waste on the upper end of the conveyor belt 5, and the conveyor belt 5 will drive the fragments of construction waste to move to the bottom of the casing 1, start the driving motor 11, and the driving motor 11 drives the second pulley 13 to rotate, and the second pulley 13 drives the first pulley 10 to rotate through the transmission belt 12, and the first pulley 10 drives the rotating barrel 18 to rotate, and the rotating barrel 18 drives all the electromagnetic blocks 19 and the striking plate 23 to rotate. When the rotating barrel 18 rotates, it will also drive all the elastic telescopic rods 31 to rotate together, and the elastic telescopic rods 31 will drive the contact balls 32 and the metal plates 33 The metal plate 33 is energized when the abutting ball 32 abutting against the outer wall of the metal plate 33 is energized, and the abutting ball 32 abutting against the outer wall of the metal plate 33 is energized. The abutting ball 32 energizes the corresponding electromagnetic block 19 through the elastic telescopic rod 31, and the electromagnetic block 19 adsorbs the fragments of the construction waste with metal on the upper end of the conveyor belt 5. It is worth noting that when the abutting ball 32 abuts against the outer wall of the metal plate 33, the electromagnetic block 19 is far away from the triangular block 42, and the electromagnetic block 19 drives the adsorbed fragments to abut against the inner wall of the abutting curved plate 15, pressurizes and crushes the fragments, and the striking plate 23 limits the fragments to prevent them from falling. When the abutting ball 32 abuts against the outer wall of another ceramic block 34, the electromagnetic block 19 loses its magnetism, and the striking plate 23 throws the crushed fragments to the outer wall of the crushing plate 16, and the closest distance between each crushing plate 16 and the striking plate 23 is two to five centimeters. The striking plate 23 will squeeze the fragments and the crushing plate 16 again, so that the fragments can be better crushed. When the striking plate 23 at the right end of the electromagnetic block 19 abuts against the curved strip 17, the abutting ball 32 will abut against the outer wall of the metal plate 33 again. At this time, the electromagnetic block 19 adsorbs the metal, and when the striking plate 23 abuts against the outer wall of the curved strip 17, the striking plate 23 The crushed pieces will fall into the upper end of the mounting base 4 through the dredging pipe 35, and the mounting base 4 will drive the pieces away. The abutment plate 20 can guide the pieces. When the striking plate 23 is separated from the outer wall of the curved strip 17, the abutment ball 32 will abut against another ceramic block 34. At this time, the electromagnetic block 19 loses its magnetic force, and the metal will fall into the guide pipe 36 and the collection box 14. In order to prevent the metal pieces on the outer wall of the electromagnetic block 19 that has lost its magnetism from being adsorbed by other electromagnetic blocks 19, the material of the striking plate 23 can effectively block the magnetism and prevent other electromagnetic blocks 19 from adsorbing the fallen metal pieces. When the striking plate 23 abuts against the inner wall of the abutting curved plate 15, the rubber sleeve 25 and the connecting pipe 26 are filled with liquid water. The contraction of the striking plate 23 will squeeze the adjacent rubber sleeve 25, and the water inside the rubber sleeve 25 will be sprayed out from the first connecting column 22. The water will reduce the dust generated by the fragments inside the casing 1 to prevent the dust from spreading. When the internal pressure of the rubber sleeve 25 increases, the blocking plate 38 will abut against the bottom of the second connecting block 39 more tightly. When the striking plate 23 is separated from the abutting against the inner wall of the abutting curved plate 15, the rubber sleeve 25 will reset. When the rubber sleeve 25 is reset, it will suck the inside of the connecting pipe 26. At this time, the blocking plate 38 will be separated from the matching port 37 and abut against the bottom of the second connecting block 39. The connecting pipe 26 will pump water into the water tank 3 to replenish water into the rubber sleeve 25. According to the above working principle, the rotating barrel 18 rotates back and forth in sequence to crush the building debris, recycle the metal materials, and reduce dust, which is easy to operate.

[0024] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed in the present invention, which should be covered by the protection scope of the present invention.
