Description

Technical Field

[0001] The present invention relates to the technical field of magnetic separation devices, and in particular to a magnetic separation treatment device and method for construction waste. Background Art

[0002] Construction waste contains a large amount of recyclable materials such as metals, plastics, and wood, especially metal materials such as iron and aluminum, which have high recycling value and reuse potential. However, due to the complexity and diversity of construction waste, the traditional manual sorting method is inefficient, costly, and cannot meet the needs of large-scale processing. Therefore, magnetic separation and processing devices have emerged. This device uses the principle of magnetic force to separate magnetic metals from construction waste through a strong magnetic field, thereby achieving efficient resource recovery.

[0020] 2. In this construction waste magnetic separation and processing device, during the operation of the leveling component, the leveling component drives the toggle component to operate synchronously, so that the speed of material dispersion is further improved during the leveling and dispersion of the construction waste materials. At the same time, the materials mixed together can be broken up, thereby improving the accuracy of subsequent material classification.

[0021] 3.

[0036] Reference Figure 1-Figure 9 A magnetic separation and processing device for construction waste comprises a mounting frame 1, on which a magnetic separation cylinder 3 is arranged, on the surface of which a transmission part 2 for conveying materials is arranged, a first collecting box 4 is arranged on one side of the mounting frame 1, and the bottom of the mounting frame 1 is located below the magnetic separation cylinder 3 and the transmission part 2, where a second collecting box 5 is arranged, a leveling component 6 arranged on the top of the mounting frame 1, one end of which is connected to the transmission part 2, and is used to level the construction waste conveyed on the transmission part 2; a toggle component 7 is arranged on the leveling component 6, and drives the toggle component 7 to move synchronously during the leveling operation of the leveling component 6, so as to separate the materials mixed together in the conveyed construction waste; a collecting component 8 is arranged in the leveling component 6, one end of which extends to the outside of the leveling component 6, and is driven by the toggle component 7 to pre-extract and clean the fine dust particles of the conveyed material.

[0037] In the present invention, when in use, the material is poured in advance at the feed end of one end of the transmission part 2, and the transmission part 2 is started to drive the construction waste material thereon to be transported to the other discharge end of the transmission part 2. A magnetic separation cylinder 3 is arranged at the discharge end. When the material is transported to the magnetic separation cylinder 3, the magnetic objects in the material can be adsorbed on the transmission part 2 through the operation of the magnetic separation cylinder 3, and the materials that cannot be adsorbed fall into the first collection box 4 as the transmission part 2 continues to transport. The materials adsorbed on the transmission part 2 lose their magnetism when passing over the second collection box 5, and then fall into the second collection box 5, thereby completing the magnetic separation and classification processing operation. In the process of material transportation, the materials poured on the transmission part 2 may be piled up together, which leads to excessive accumulation of magnetic objects in the material during subsequent magnetic separation, and the magnetic separation cylinder 3 has a limited magnetic suction distance and cannot be adsorbed in time, resulting in poor magnetic separation effect. In this scheme, by 2, a leveling component 6 is arranged above the conveying part 2. During the material conveying operation of the conveying part 2, the power source generated by the conveying of the conveying part 2 drives the leveling component 6 to operate synchronously, so as to level the construction waste materials accumulated during the conveying process to avoid excessive accumulation of materials. During the leveling operation, the materials can be dispersed to make the materials dispersed more evenly, thereby improving the magnetic separation effect of the device. During the leveling operation of the conveying materials, the leveling component 6 drives the toggle component 7 to operate synchronously, so that the speed of material dispersion is further improved during the leveling and dispersing process of the construction waste materials. At the same time, the materials mixed together can be broken up to improve the accuracy of subsequent material classification. When the toggle component 7 is running, it can also drive the collecting component 8 to operate synchronously, so as to pre-extract, adsorb and collect smaller dust particles mixed in the construction waste materials conveyed on the conveying part 2, reduce the dust phenomenon in the working environment, and reduce the influence of dust on the magnetic separation drum 3 during operation.

[0038] It should be noted that the output end of the driving unit 31 is connected to the magnetic separation cylinder 3, the cylinder size of the magnetic separation cylinder 3 is the same as that of the transmission roller 33, and the transmission belt 34 is wound around the transmission roller 33 and the surface of the magnetic separation cylinder 3. When the driving unit 31 is started, the transmission unit and the magnetic separation cylinder 3 are operated. In this scheme, during the magnetic separation operation, the construction waste to be magnetically separated is initially crushed by the crusher and then poured onto the transmission unit 2. When the construction waste is transmitted to the magnetic separation cylinder 3, the magnetic construction waste objects in the construction waste are magnetically adsorbed on the magnetic field surface of the magnetic separation cylinder 3 through the transmission belt 34 after the magnetic separation cylinder 3 is started. Non-magnetic objects are not affected by the magnetic field and will continue to fall into the first collection box 4 as the transmission belt 34 moves and are eliminated. As the magnetic construction waste objects adsorbed on the transmission belt 34 at the magnetic separation cylinder 3 gradually move away from the magnetic separation cylinder 3, the magnetic adsorption force weakens, and then they break away from the transmission belt 34 and fall into the second collection box 5.

[0039] In a preferred embodiment, referring to Figure 3 , Figure 4, Figure 5 and Figure 6 The transmission part 2 includes a driving part 31 connected to the magnetic separation drum 3, a transmission roller 33 is rotatably connected to the mounting frame 1 through a bearing, a support roller 32 is rotatably connected to the mounting frame 1 through a bearing, a transmission belt 34 is wound around the transmission roller 33 and the magnetic separation drum 3, and the leveling component 6 includes a driving wheel 60 fixed at one end of the transmission roller 33, the surface of the driving wheel 60 is connected to the driven wheel 61 through a synchronous belt drive, a first connecting shaft 62 is fixed at the axis of the driven wheel 61, a rotating drum 63 is fixed to one end of the first connecting shaft 62, a second connecting shaft 65 is fixed to one end of the rotating drum 63, the second connecting shaft 65 is rotatably connected to the mounting frame 1 through a bearing, a wear-resistant layer is provided on the surface of the rotating drum 63, and symmetrically arranged spiral blades 64 are provided on the surface of the rotating drum 63, and the spiral blades 64 and the wear-resistant layer are both made of ceramic composite materials.

[0040] In the above scheme, the driving part 31 is driven by a reduction motor. Under the drive of the driving part 31, the magnetic separation drum 3 and the transmission roller 33 are driven to rotate synchronously, so that the construction waste materials on the conveyor belt 34 are transported and operated. The surface of the conveyor belt 34 is provided with a baffle plate made of rubber material to prevent the material from spilling. When the transmission part 2 is running, one end of the transmission roller 33 is started to connect the driving wheel 60, and the drum 63 is driven to rotate with the cooperation of various components. When the material on the conveyor belt 34 is continuously transported, when passing through the bottom of the drum 63, due to the excessive accumulation of materials, the excessive materials can be intercepted under the obstruction of the drum 63, so that the materials being transported can be flattened. On the other hand, spiral blades 64 are provided on the surface of the drum 63. When the two groups of symmetrical spiral blades 64 come into contact with the transported materials, they can disperse the materials accumulated in the middle part, so that the materials are flatter. Due to the setting of the spiral blades 64, when the materials are transported, the spiral blades 64 can be used to crush larger pieces of construction waste, so that it also has the effect of crushing the materials.

[0041] In a preferred embodiment, referring to Figure 6 and Figure 7The toggle assembly 7 includes a bevel gear 71 fixed on the surface of the second connecting shaft 65, a matching gear 72 is meshed on the surface of the bevel gear 71, a connecting rod 73 is fixed at the axis of the matching gear 72, one end of the connecting rod 73 is rotatably connected to the mounting frame 1 through a bearing, a cam 74 is fixed at one end of the connecting rod 73, a reciprocating member is provided on the surface of the cam 74, and the reciprocating member includes a slide rod 75 that fits on the surface of the cam 74, one end of the slide rod 75 passes through the second connecting shaft 65 and extends to the inside of the rotating drum 63 where the connecting frame 7 is fixed 6. An extrusion spring 77 is fixed between the connecting frame 76 and the inner wall of the rotating cylinder 63. The extrusion spring 77 is sleeved on the surface of the sliding rod 75. The surface of the connecting frame 76 is rotatably connected to a toggle rod 78 through a pin shaft. An opening 79 is provided on the surface of the rotating cylinder 63. One end of the toggle rod 78 passes through the opening 79 and extends to the outside of the rotating cylinder 63. The surface of the toggle rod 78 is rotatably connected in the opening 79 through a pin shaft. A protective sleeve 791 is sleeved on the surface of the toggle rod 78. One end of the protective sleeve 791 is fixedly connected to the outer wall of the rotating cylinder 63.

[0042] By adopting the above scheme, during the rotation of the drum 63, the second connecting shaft 65 at one end drives the bevel gear 71 to rotate synchronously, thereby applying a reciprocating force to the slide bar 75, and the slide bar 75 drives the connecting frame 76 to reciprocate horizontally, and finally drives the toggle rod 78 to swing back and forth. When the toggle rod 78 swings back and forth, it contacts the material transported on the lower transmission part 2, so that when the construction waste is leveled, the swinging effect of the toggle rod 78 can be utilized to accelerate the dispersion of the material, saving the time for leveling and dispersion. At the same time, when the toggle rod 78 swings, multiple construction wastes mixed together can be separated to avoid the non-magnetic materials being adsorbed together during the subsequent magnetic separation and classification processing, thereby improving the accuracy of the magnetic separation, adsorption and classification processing of the device.

[0043] It should be noted that the slide rod 75 slides through the second connecting shaft 65, and drives the cam 74 to rotate when the bevel gear 71 and the mating gear 72 are in meshing transmission. When the cam 74 rotates, it fits with one end of the slide rod 75, and then cooperates with the extrusion spring 77. When the second connecting shaft 65 and the slide rod 75 rotate, the connecting frame 76 fixed at one end of the slide rod 75 can also be squeezed by the cam 74 to make horizontal reciprocating motion.

[0044] In a preferred embodiment, referring to Figure 2 , Figure 7 , Figure 8 and Fig. 9The collecting assembly 8 includes a filter screen 81 arranged at one end of a toggle rod 78, a cavity a82 is provided inside the toggle rod 78, a delivery pipe a83 is connected to one end of the toggle rod 78, a cavity b84 is provided inside the connecting frame 76, one end of the delivery pipe a83 is connected to the connecting frame 76, a delivery pipe b85 is fixed to one end of the connecting frame 76, a discharge piece is provided at the end of the delivery pipe b85, and the discharge piece includes a connecting tube 86 fixed to the end of the delivery pipe b85, and the connecting tube 86 is embedded and installed in the first connecting shaft 62, A first valve 87 is arranged between the delivery pipe b85 and the connecting cylinder 86, a piston 88 is slidably connected inside the connecting cylinder 86, a moving rod 89 is fixed to one side of the piston 88, one end of the moving rod 89 is fixedly connected to the connecting frame 76, one end of the connecting cylinder 86 extends to the outside of the first connecting shaft 62 and a dust collecting box 892 is arranged, a second valve 891 is arranged at one end of the connecting cylinder 86, a cover plate 893 is arranged on the top of the dust collecting box 892, and a support rod 9 connected to the mounting frame 1 is fixed to the bottom of the dust collecting box 892.

[0045] By adopting the above scheme, during the reciprocating motion of the connecting frame 76, the moving rod 89 can be driven to move synchronously, and the moving rod 89 drives the piston 88 to slide back and forth inside the connecting cylinder 86, and an adsorption force is generated at the filter screen 81 at one end of the toggle rod 78, so that the fine dust particles in the transported construction waste materials can be adsorbed and collected, and then transported to the dust collection box 892 through the moving rod 89 for centralized storage. By adopting this structure, a large amount of dust is avoided during the material transportation process to pollute the working environment. At the same time, the dust suction operation can prevent dust from adhering to the working magnetic separation cylinder 3, affecting the magnetic attraction effect of the magnetic separation cylinder 3, reducing the occurrence of faults, and improving the stability of the device operation. Overall, due to the cooperation between the toggle assembly 7 and the collecting assembly 8, when the toggle rod 78 swings back and forth, the dust suction range of the collecting assembly 8 is further improved, so that the dust suction effect is better, wherein a cover plate 893 is provided at the bottom of the dust collecting box 892, which is convenient for centralized cleaning of the dust in the dust collecting box 892, and an exhaust hole is provided at the top of the cover plate 893, and a dust filter is provided in the exhaust hole, so that the structure can operate normally, wherein the first valve 87 and the second valve 891 are one-way valves.

[0046] A method for using a construction waste magnetic separation and treatment device mainly comprises the following steps:

[0047] Step A: When in use, the material is poured onto one end of the transmission part 2 in advance, and the construction waste material thereon is driven by power to be transported to the other end, at which a magnetic separation drum 3 is provided. When the material is transported to the magnetic separation drum 3, the magnetic objects in the material can be adsorbed onto the transmission part 2 through the operation of the magnetic separation drum 3, while the material that cannot be adsorbed falls into the first collection box 4 as the transmission part 2 continues to transport. The material adsorbed on the transmission part 2 loses its magnetism when passing over the second collection box 5, and then falls into the second collection box 5, thereby completing the magnetic separation and classification processing operation;

[0048] Step B: During the material conveying process, the transmission part 2 drives the leveling component 6 to operate synchronously to level the materials that are piled too high, and cooperates with the shifting component 7 to break up the mixed materials. The shifting component 7 can also drive the collecting component 8 to operate synchronously during operation, so as to pre-extract, adsorb and collect the dust particles mixed in the construction waste materials conveyed by the transmission part 2.

[0049] The above description is only a preferred specific implementation manner 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 scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

5. A construction waste magnetic separation and treatment device according to claim 4, characterized in that: The discharge member comprises a connecting tube (86) fixed to the end of a conveying pipe b (85), the connecting tube (86) being embedded and installed in a first connecting shaft (62), a first valve (87) being arranged between the conveying pipe b (85) and the connecting tube (86), a piston (88) being slidably connected inside the connecting tube (86), a moving rod (89) being fixed to one side of the piston (88), one end of the moving rod (89) being fixedly connected to a connecting frame (76), one end of the connecting tube (86) extending to the outside of the first connecting shaft (62) being arranged with a dust collecting box (892), one end of the connecting tube (86) being arranged with a second valve (891), a cover plate (893) being arranged on the top of the dust collecting box (892), and a supporting rod (9) connected to the mounting frame (1) being fixed to the bottom of the dust collecting box (892).

6. A method for using a construction waste magnetic separation and treatment device, using the construction waste magnetic separation and treatment device according to claim 5, characterized in that: The main steps include: Step A: When in use, the material is poured onto one end of the transmission part (2) in advance, and the construction waste material thereon is driven by power to be transported to the other end, and a magnetic separation cylinder (3) is provided at the other end. When the material is transported to the magnetic separation cylinder (3), the magnetic separation cylinder (3) can work to adsorb the magnetic objects in the material onto the transmission part (2), while the material that cannot be adsorbed falls into the first collection box (4) as the transmission part (2) continues to transport. The material adsorbed on the transmission part (2) loses its magnetism when passing above the second collection box (5), and then falls into the second collection box (5), thereby completing the magnetic separation and classification processing operation; Step B: During the material conveying process, the conveying part (2) drives the leveling component (6) to operate synchronously, so as to level the materials that are piled too high, and at the same time cooperates with the shifting component (7) to break up the materials that are mixed together. When the shifting component (7) is in operation, it can also drive the collecting component (8) to operate synchronously, so as to pre-extract, adsorb and collect the dust particles mixed in the construction waste materials conveyed by the conveying part (2).
