Description

Technical Field

[0001] This utility model relates to the field of construction waste treatment technology, specifically a magnetic separation treatment structure for construction waste. Background Technology

[0002] Construction waste processing equipment refers to equipment for collecting, crushing, and separating construction waste. Different equipment and structures can be used depending on the stage of the work. For example, magnetic separation can separate magnetic and non-magnetic metals in construction waste and can recycle and reuse metal materials such as iron and steel in construction waste.

[0003] A search revealed Chinese patent CN214637303U, which discloses a device for processing construction waste. The device includes a housing with mounting plates fixedly installed on the lower left and right ends. Two support legs are fixedly installed on the lower ends of each mounting plate, and an electrical control box is mounted on a fixed rod at the upper end of one of the mounting plates. A feed hopper is fixedly installed on the upper end of the housing, and a discharge hopper is fixedly installed on the lower end. Both the feed hopper and discharge hopper are integrally formed with the housing and are internally connected. Fasteners are fixedly installed on one side of the front end of the housing. Magnetic separation components are provided in the upper part of the inner cavity and the upper part of the inner cavity. This device for processing construction waste is scientifically designed and structurally sound. It can pre-treat construction waste, removing iron-containing impurities. Furthermore, the removal of iron-containing impurities adhering to the electromagnetic rod is simpler and more convenient, resulting in higher efficiency compared to traditional iron removal devices.

[0004] The aforementioned device can separate construction waste falling into the container through the magnetic separation component. However, the structure adopts a top-down feeding method. When construction waste is fed in, adjacent construction waste will block each other. At this time, the construction waste blocking each other will reduce the screening function of the magnetic separation component. During operation, some magnetic metals will not be attracted by other construction wastes and need to be fed in and screened again, which is quite troublesome to use.

[0005] Therefore, we propose a magnetic separation structure for construction waste treatment. Utility Model Content

[0006] The purpose of this utility model is to provide a magnetic separation treatment structure for construction waste to solve the problems raised in the prior art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a magnetic separation treatment structure for construction waste, including a fixed frame, wherein a conveyor belt assembly 1, a conveyor belt assembly 2, and a conveyor belt assembly 3 are respectively installed inside the fixed frame, a fixed ring is fixedly installed inside the fixed frame, and a separation cylinder is rotatably connected inside the fixed ring;

[0008] A drive mechanism is installed on the outside of the separation cylinder, and a spiral tube is fixedly installed inside the separation cylinder to assist in the separation of construction waste.

[0009] A control mechanism is mounted on the outside of the fixed frame, a hydraulic cylinder is mounted on the outside of the control mechanism, a mounting bracket is mounted on the output end of the hydraulic cylinder, and multiple sets of electromagnetic rods are mounted on the outside of the mounting bracket.

[0010] Preferably, the separating cylinder has an inclined structure, the first conveyor belt assembly is located at the inlet of the separating cylinder, and the second and third conveyor belt assemblies are located at the outlet of the separating cylinder and are arranged vertically.

[0011] Preferably, multiple sets of fixing rings are symmetrically arranged on the outside of the fixing frame, and both ends of the separating cylinder are supported by fixing rings.

[0012] Preferably, the driving mechanism includes a protective cylinder, the outer surface of which is fixedly installed with the interior of the fixed frame, a first motor is installed inside the protective cylinder, a first gear is installed at the output end of the first motor, a second gear meshes with the outer teeth of the first gear, and the outer surface of the separating cylinder is fixedly installed with the interior of the second gear.

[0013] Preferably, the control mechanism includes a fixed plate, the outer surface of which is fixedly installed with the interior of the fixed frame, a threaded rod is rotatably connected to the interior of the fixed plate, a movable frame is threadedly connected to the outer surface of the threaded rod, and the base of the hydraulic cylinder is fixedly installed with the outer surface of the movable frame.

[0014] Preferably, a limiting rod is fixedly installed on the outer surface of the fixed plate, and the outer surface of the limiting rod is slidably connected to the inside of the movable frame. A second motor is installed on the outside of the fixed plate, and the output end of the second motor is fixedly installed to one end of the threaded rod.

[0015] Preferably, the electromagnetic rod is horizontal to the axis of the separating cylinder, and the hydraulic cylinder can drive the electromagnetic rod to move above the conveyor belt assembly three.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This application utilizes the coordination between the separation cylinder, the spiral tube, and the control mechanism. After the construction waste inside the separation cylinder is fed into the inlet, it rotates under the action of the separation cylinder, thus separating the construction waste that is attached to each other. The spiral tube can convey and transfer the construction waste, allowing it to move and separate. Then, the electromagnetic rod, after being energized, can attract the construction waste containing magnets. During processing, the control mechanism can drive the electromagnetic rod to move to the outside of the separation cylinder. Then, when the electromagnetic rod is de-energized, the attracted construction waste can be discharged to the outside of the conveyor belt assembly. This achieves the function of rotating and separating construction waste, which helps to reduce the attraction effect caused by non-magnetic waste blocking magnetic waste.

[0018] 2. This application, by setting up components such as a protective cylinder and gear two, can protect the meshing position or teeth of gear one and gear two through the protective cylinder. The meshing of gear one and gear two can control the rotation of the separation cylinder. At this time, the separation cylinder will rotate stably under the action of the fixing rings on both sides, which can perform separation operation on the internal separation cylinder and improve the treatment effect of magnetic construction waste.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example:

[0027] like Figure 1 - Figure 5 As shown, this utility model provides a technical solution for a magnetic separation treatment structure for construction waste. The structure includes a fixed frame 1, inside which conveyor belt assembly 2, conveyor belt assembly 3, and conveyor belt assembly 4 are respectively installed. A fixing ring 5 is fixedly installed inside the fixed frame 1, and a separation cylinder 6 is rotatably connected inside the fixing ring 5. Multiple sets of fixing rings 5 ​​are symmetrically arranged outside the fixed frame 1. Both ends of the separation cylinder 6 are supported by the fixing rings 5. The separation cylinder 6 has an inclined structure. Conveyor belt assembly 2 is located at the inlet of the separation cylinder 6. Conveyor belt assembly 3 and conveyor belt assembly 4 are connected to the separation cylinder 6. Belt assembly 3 4 is located at the outlet of separation cylinder 6 and is arranged vertically. Conveyor belt assembly 1 2, conveyor belt assembly 2 3 and conveyor belt assembly 3 4 all include components such as conveyor belts, rotating shafts and motors. Multiple sets of conveyor belts can be connected to external feeding devices or other classified conveyor belts to facilitate the separate transfer of magnetic or non-magnetic metals. When in use, external construction waste enters the inlet of separation cylinder 6 through conveyor belt assembly 1 2. Then, under the rotation of separation cylinder 6, the mixed construction waste can be rotated and separated, reducing the stacking of construction waste.

[0028] A drive mechanism 7 is installed on the outside of the separating cylinder 6. The drive mechanism 7 includes a protective cylinder 701. The outer surface of the protective cylinder 701 is fixedly installed inside the fixed frame 1. A first motor 702 is installed inside the protective cylinder 701. A gear 703 is installed at the output end of the first motor 702. A gear 704 meshes with the teeth of the gear 703. The outer surface of the separating cylinder 6 is fixedly installed inside the gear 704. The first motor 702 can control the rotation of the gear 703. The meshing of the gear 703 and the gear 704 can control the rotation of the separating cylinder 6. The protective cylinder 701 can protect the first motor 702, the gear 703, and the gear 704 from external impact, reducing the external influence on the gears 703 and 704.

[0029] The interior of the separation cylinder 6 is fixedly equipped with a spiral tube 8 to assist in the separation of construction waste. The rotation of the spiral tube 8 and the separation cylinder 6 can cause the construction waste entering the separation cylinder 6 to rotate. At this time, the construction waste that is squeezed against each other will be turned over or separated, and the magnetic metal and non-magnetic metal can be controlled to turn over.

[0030] A control mechanism 9 is installed on the outside of the fixed frame 1. The control mechanism 9 includes a fixed plate 901. The outer surface of the fixed plate 901 is fixedly installed inside the fixed frame 1. A threaded rod 902 is rotatably connected inside the fixed plate 901. A movable frame 903 is threadedly connected to the outer surface of the threaded rod 902. The base of the hydraulic cylinder 10 is fixedly installed on the outer surface of the movable frame 903. The control mechanism 9 can drive the electromagnetic rod 12 to move. Under the rotation of the threaded rod 902, the movable frame 903 can move inside the fixed frame 1, which can further drive the movable frame 903 to move.

[0031] A limiting rod 904 is fixedly installed on the outer surface of the fixed plate 901. The outer surface of the limiting rod 904 is slidably connected to the inside of the movable frame 903. A second motor 905 is installed on the outside of the fixed plate 901. The output end of the second motor 905 is fixedly installed to one end of the threaded rod 902. The linear movement of the movable frame 903 can be limited by the limiting rod 904. At this time, the movable frame 903 can move linearly stably. The rotation of the threaded rod 902 can be controlled by the second motor 905.

[0032] A hydraulic cylinder 10 is installed on the outside of the control mechanism 9. A mounting frame 11 is installed on the output end of the hydraulic cylinder 10. Multiple sets of electromagnetic rods 12 are installed on the outside of the mounting frame 11. The electromagnetic rods 12 are horizontal with the axis of the separation cylinder 6. The hydraulic cylinder 10 can drive the electromagnetic rods 12 to move above the conveyor belt assembly 3 4. When performing magnetic sorting, the threaded rod 902 causes the moving frame 903 to move towards one end of the separation cylinder 6. Then, the hydraulic cylinder 10 can push the electromagnetic rods 12 into the interior of the separation cylinder 6. At this time, the electromagnetic rods 12 will be close to one side wall of the separation cylinder 6. Then, under the rotation of the separation cylinder 6, the electromagnetic rods 12 are energized. At this time, the electromagnetic rods 12 can separate the construction waste containing magnets inside the separation cylinder 6. Under the rotation of the separation cylinder 6 and the spiral tube 8, the construction waste can be flipped over, which can reduce the impact of stacking on the magnetic metal.

[0033] Working principle: During operation, construction waste enters the interior of the separation cylinder 6 through the conveyor belt assembly 2. At this time, the separation cylinder 6 rotates under the control of motor 702, gear 1 703, and gear 2 704. Under the action of the separation cylinder 6 and the spiral tube 8, the stacked construction waste can rotate and flip over. At this time, the threaded rod 902 drives the moving frame 903 to move towards one end of the separation cylinder 6. When the moving frame 903 approaches one end of the separation cylinder 6, the hydraulic cylinder 10 controls the electromagnetic rod 12 to enter the interior of the separation cylinder 6. After the electromagnetic rod 12 is energized, it can attract the construction waste containing magnetism. At this time, the non-magnetic construction waste can fall outside the conveyor belt assembly 3. The electromagnetic rod 12 is first moved upward by the hydraulic cylinder 10, and then moved to the outside of the conveyor belt assembly 4 under the control of the threaded rod 902 and the power is cut off to release the collected construction waste. After repeating the operation, the construction waste can be recycled.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
