Description

Technical Field

[0001] This utility model relates to the field of electromagnetic iron removal equipment technology, specifically to an intelligent, energy-saving, high-power, automatic suction and unloading electromagnetic iron remover. Background Technology

[0002] In existing technologies, electromagnetic separators consist of an electromagnetic attractor and a control box. The electromagnetic attractor is directly mounted on the conveyor belt, and its start or stop can be manually controlled by the control box. Once the control box activates the electromagnetic attractor, it remains in the active state regardless of whether the conveyor belt contains ferrous materials. However, continuous energization of the electromagnetic attractor leads to excessively high coil temperatures, increased resistance, and decreased suction force. This limits the power output of the electromagnetic attractor, results in high energy consumption, and a short lifespan. Furthermore, since existing electromagnetic attractors are directly mounted on the conveyor belt, if the material on the belt is too high or if there are sharp, flaky materials during transport, the upper end of the material may touch the bottom of the electromagnetic attractor and become stuck. As the conveyor belt continues to move, the stuck material may tear the conveyor belt or be squeezed out and fall off. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an intelligent, energy-saving, high-power automatic suction and unloading electromagnetic separator, so as to solve the problems of high energy consumption and short service life caused by the existing electromagnetic separators being in working state regardless of whether the material being conveyed by the conveyor belt contains iron after being turned on.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] This application provides an intelligent, energy-saving, high-power, automatic electromagnetic separator. The electromagnetic separator is installed above a conveyor belt and includes a metal detector, an electromagnetic suction device, a moving system, and a control system. The metal detector and the moving system are installed sequentially on the same conveyor belt. The metal detector is used to detect whether the material on the conveyor belt contains iron. The moving system is equipped with a moving device. The control system is communicatively connected to the metal detector and the moving device, and is used to control the movement of the moving device and the electromagnetic suction and unloading of iron.

[0006] Furthermore, the moving system includes a moving device, four load-bearing columns, a pair of load-bearing beams, and a track. The bottom ends of the four load-bearing columns are fixedly installed around the perimeter of the conveyor belt. The pair of load-bearing beams and the track are horizontally installed on the top of the load-bearing columns. The load-bearing beams and the track extend from one side of the conveyor belt to the outer edge of the other side of the conveyor belt. The moving device is slidably installed on the track, and the moving device and the track form a lateral rolling connection. The electromagnetic suction is installed on the moving device.

[0007] Furthermore, the electromagnetic suction is installed on the moving device, which is used to move the electromagnetic suction to the top of the conveyor belt to attract iron or to the outside of the conveyor belt to unload iron.

[0008] Furthermore, the moving device includes a pair of crossbeams, a pair of longitudinal beams, and a driving device. The pair of crossbeams and the pair of longitudinal beams form a frame structure. Casters are installed at the bottom of the crossbeams and are rolled on the track. The driving device is connected to the casters and is used to drive the casters to move along the track. The electromagnetic attraction is installed on the longitudinal beams.

[0009] Furthermore, an adjustable height suspension device is provided between the electromagnetic suction and the longitudinal beam.

[0010] Furthermore, the adjustable height suspension device includes four sets of adjustable components. The four sets of adjustable components are respectively arranged around the upper end face of the electromagnetic attractor and between the longitudinal beam. Each set of adjustable components includes a lifting ring, a threaded rod, and a nut. The lifting ring is connected to the upper end face of the electromagnetic attractor by a shackle. The bottom end of the threaded rod is fixedly connected to the lifting ring. The nut is fixedly installed at the top of the longitudinal beam, and the top end of the threaded rod is vertically installed inside the nut.

[0011] Furthermore, a rotating handle is installed at the top of the threaded rod.

[0012] Furthermore, anti-derailment limiting baffles are installed on the outer edges of the opposite ends of the track.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By employing the aforementioned intelligent, energy-saving, high-power automatic electromagnetic separator, a metal detector is positioned in front of the conveyor belt in the conveying direction. When the metal detector detects iron mixed in with the material on the conveyor belt, it sends an action signal to the control system. The control system then controls a moving device to move, which moves the electromagnetic separator above the conveyor belt to attract the iron from the material being transported. After attracting the iron, it automatically moves outside the conveyor belt within a set time to unload it. Because the electromagnetic separator is normally stationary outside the conveyor belt and only becomes energized and moves when iron is detected, it achieves energy saving and extends its service life when no iron is detected.

[0015] 2. Since one end of the load-bearing beam and the track extends to the outside of the conveyor belt, the electromagnetic attractor can be moved along the track by the moving device to standby outside the conveyor belt. Since the electromagnetic attractor is located outside the conveyor belt at this time, the material on the conveyor belt will not come into contact with the electromagnetic attractor. Therefore, it can effectively prevent the phenomenon of sheet-like material in the material from touching and getting stuck with the electromagnetic attractor, thus tearing the conveyor belt or being squeezed out of the conveyor belt and falling off.

Detailed Implementation

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] First, to better understand the intelligent energy-saving high-power automatic electromagnetic separator 10 in this embodiment, its application scenario will be briefly explained. Considering the actual situation of a quarry, the amount of iron material that needs to be removed is not large. During the mining process, occasionally a small amount of excavator bucket teeth and roots, blasting machine drill bits and pins, and drill bits and rods from drilling rigs may fall off and mix with the stone. However, these small amounts of hard iron material can be very damaging to the crushing and pulverizing equipment. Therefore, it is necessary to remove the hard iron material from the stone.

[0024] See appendix Figure 1 To be continued Figure 2 As shown, this embodiment provides an intelligent, energy-saving, high-power automatic electromagnetic separator 10, which is installed on a conveyor belt 20. The electromagnetic separator includes a metal detector 100, an electromagnetic suction device 300, a moving system 200, and a control system.

[0025] See attached document Figure 1 Appendix Figure 2 and appendix Figure 4 As shown, in this embodiment, along the material conveying direction of the conveyor belt 20, the metal detector 100 and the moving system 200 are arranged sequentially in the front and rear directions of the conveyor belt 20. The metal detector 100 is arranged in front of the moving system 200. That is, during the conveying process, the material on the conveyor belt 20 is first detected by the metal detector 100. After being detected by the metal detector 100, the material moves to the position of the conveyor belt 20 where the electromagnetic suction 300 is installed with the help of the conveyor belt 20.

[0026] In this embodiment, the metal detector 100 is used to detect the iron content of the material conveyed on the conveyor belt 20, that is, to detect whether the material contains iron. It can directly use an iron removal detector in the prior art (with wireless communication function, such as the iron removal product with wireless radio frequency technology produced by Shandong Huatai Magnetoelectric Technology Co., Ltd.) so that it can be wirelessly connected to the subsequent controller. The specific structure and principle of the iron removal device will not be described here.

[0027] Continue to refer to the appendix Figure 1 and attached Figure 2 As shown, the mobile system 200 includes a mobile device 203, and an electromagnetic suction 300 is mounted on the mobile device 203. The mobile device 203 is used to drive the electromagnetic suction 300 to attract iron above the conveyor belt 20 or to move outside the conveyor belt to unload iron. The control system is communicatively connected to the metal detector 100 and the mobile device 203. The control system is used to control the movement of the mobile device 203 and the attraction and unloading of iron by the electromagnetic suction 300. In this embodiment, the control system adopts the existing PLC control system, and the PLC control system communicates with the mobile device 203, the electromagnetic suction 300, and the metal detector 100 to transmit signals.

[0028] A metal detector 100 is installed in front of the conveyor belt 20 in the conveying direction. When the metal detector 100 detects iron mixed in with the material on the conveyor belt 20, it sends an action signal to the control system. The control system then controls the moving device 203 to move and the electromagnetic suction 300 to be energized. The moving device 203 moves the electromagnetic suction 300 above the conveyor belt 20 to attract iron from the material being conveyed on the conveyor belt 20. After attracting iron, it automatically moves outside the conveyor belt 20 within a set time to unload the iron. Since the electromagnetic suction 300 is normally stationary outside the conveyor belt 20, it effectively prevents the conveyor belt from being torn. The electromagnetic suction 300 is only energized and moves when iron is detected; otherwise, it is not energized, thus achieving energy saving and extending service life.

[0029] Continue to refer to the appendix Figure 1 and attached Figure 2 As shown, the moving system 200 includes a moving device 203, four load-bearing columns 204, a pair of load-bearing beams 201, and a track 202. The bottom ends of the four load-bearing columns 204 are vertically fixed around the conveyor belt 20. The pair of load-bearing beams 201 and the track 202 are horizontally installed on the top of the load-bearing columns 204. That is, one load-bearing beam 201 and the track 202 are horizontally installed on the top of the pair of horizontally arranged load-bearing columns 204. The load-bearing beams 201 and the track 202 extend from one side of the conveyor belt 20 to the outside of the other side of the conveyor belt 20. The moving device 203 is rolled on the track 202, and the moving device 203 and the track 202 form a horizontal rolling connection. The electromagnetic suction 300 is installed on the moving device 203. By extending one end of the load-bearing beam 201 and the track 202 to the outside of the conveyor belt 20, the electromagnetic suction 300 can be moved to the outer edge of the track 202 via the moving device 203 when it is not in operation. That is, the electromagnetic suction 300 is moved to the position outside the conveyor belt 20. In this way, the material on the conveyor belt 20 will not come into contact with the electromagnetic suction 300 during the forward conveying process. This can also avoid the phenomenon that the material is too high or some flaky and sharp material will come into contact with the electromagnetic suction 300 and get stuck during the conveying process, thus preventing the conveyor belt 20 from being torn or the material from being squeezed out of the conveyor belt 20.

[0030] See attached document Figure 1 and attached Figure 3As shown, in this embodiment, the moving device 203 includes a pair of crossbeams 2031, a pair of longitudinal beams 2032, and a driving device. The pair of crossbeams 2031 and the pair of longitudinal beams 2032 form a frame structure. Casters 2034 are installed at the bottom of the crossbeams 2031. The casters 2034 are rolled on the track 202. The driving device is connected to the casters 2034 and is used to drive the casters 2034 to move along the track 202. An electromagnetic suction device 300 is installed on the longitudinal beams 2032. To prevent the casters 2034 from slipping off the track 202 during movement, anti-derailment limiting baffles 400 are installed at the outer edges of the opposite ends of the track 202.

[0031] In this embodiment, the drive device uses a three-in-one motor, which is connected to a controller (PLC control system) to control the operation of the three-in-one motor. By using a frame structure composed of crossbeams 2031 and longitudinal beams 2032, the stability of the moving device 203 when moving on the conveyor belt 20 can be increased.

[0032] See attached document Figure 3 As shown, in order to flexibly adjust the suspension height of the electromagnetic suction 300 according to the actual conveying volume of materials on the conveyor belt 20, in some embodiments, an adjustable height suspension device is provided between the electromagnetic suction 300 and the longitudinal beam 2032. The installation height of the electromagnetic suction 300, i.e., the vertical distance between the bottom surface of the electromagnetic suction 300 and the material on the conveyor belt 20, can be adjusted by adjusting the adjustable height suspension device. It can be understood that when the stack height of the material conveyed on the conveyor belt 20 is high, the installation height of the electromagnetic suction 300 needs to be adjusted upwards; conversely, when the stack height of the material conveyed on the conveyor belt 20 is low, the installation height of the electromagnetic suction 300 can be adjusted downwards.

[0033] Specifically, the adjustable height suspension device includes four sets of adjustable components. The four sets of adjustable components are respectively set around the upper end face of the electromagnetic suction 300 and between the longitudinal beam 2032. Each set of adjustable components includes a shackle 2037, a lifting ring 2036, a threaded rod 2035 and a nut 2033. The lifting ring 2036 is connected to the shackle 2037 set on the upper end face of the electromagnetic suction 300. The bottom end of the threaded rod 2035 is fixedly connected to the lifting ring 2036. The nut 2033 is fixedly installed on the top end of the longitudinal beam 2032, and the top end of the threaded rod 2035 is vertically installed in the nut 2033.

[0034] When the installation height of the electromagnetic attractor 300 needs to be adjusted, the nut 2033 can be rotated clockwise or counterclockwise. Since the top of the threaded rod 2035 is vertically installed inside the nut 2033, when the nut 2033 is rotated, the threaded rod 2035 will rise or fall vertically, thereby causing the electromagnetic attractor 300 below to rise or fall vertically accordingly, thus achieving the adjustment of the installation height of the electromagnetic attractor 300.

[0035] In some embodiments, a rotating handle is also installed on the nut 2033 to facilitate the adjustment of the threaded rod 2035. When adjusting the height of the threaded rod 2035, the nut 2033 can be rotated by turning the handle.

[0036] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
