[0028] Please see Figures 1-4 .

[0029] Some embodiments of this application disclose a magnetic separator feed screening device, including a positioning frame 1 and a trough-shaped coarse grate body 2. The trough-shaped coarse grate body 2 is snapped into the inside of the magnetic separator feed inlet. The positioning frame 1 is installed at the outer end of the trough-shaped coarse grate body 2. The lower surface of the positioning frame 1 abuts against the upper surface of the magnetic separator feed inlet. Two sets of slots are provided on the upper surface of the positioning frame 1. A cleaning mechanism 4 for cleaning debris accumulated inside the trough-shaped coarse grate body 2 is slidably connected inside the two sets of slots of the positioning frame 1. Limiting mechanisms 3 are installed on the left and right sides of the positioning frame 1. A detection mechanism 7 is installed on the upper surface of the positioning frame 1. A protective mechanism 9 is installed at the top of the detection mechanism 7.

[0030] Specifically, by activating the cleaning mechanism 4, debris accumulated inside the multiple feed inlets of the main body 2 of the coarse grate is pushed away, thus shortening the time spent by subsequent workers in cleaning the debris inside the multiple feed inlets of the main body 2 of the coarse grate, thereby improving the practicality of the device; the coarse grate body 2 reduces the accumulation of lump coal at the feed inlet of the magnetic separator, increasing the service life of the drum skin; at the same time, it ensures that the medium liquid will not overflow, causing waste of medium usage, greatly saving the cost of medium usage, and reducing the need for personnel to clean up.

[0031] The cleaning mechanism 4 includes two sets of sliding plates 401, which are slidably connected to the two sets of slots in the positioning frame 1. An L-shaped connecting plate 402 is provided on the upper surface of the two sets of sliding plates 401. A slot is opened at the top of the L-shaped connecting plate 402. An electric telescopic rod 404 is installed inside the slot of the L-shaped connecting plate 402. A fixing plate 403 is installed at the output end of the electric telescopic rod 404. Multiple cleaning blocks 405 are provided on the lower surface of the fixing plate 403. The positions of the multiple cleaning blocks 405 are located at the top of the multiple feed inlets inside the positioning frame 1.

[0032] Specific method: When a large amount of debris accumulates in the multiple feed inlets inside the main body 2 of the coarse grate, the two sets of sliding plates 401 are pushed to connect them to the two sets of slots in the positioning frame 1. This positions the subsequent sets of cleaning blocks 405 directly above the multiple feed inlets inside the positioning frame 1. Then, by activating the electric telescopic rod 404, the fixing plate 403 is pushed, causing the multiple sets of cleaning blocks 405 to move downwards. As the subsequent sets of cleaning blocks 405 move downwards, they push away the debris accumulated in the coarse grate. The device removes debris from the multiple feed inlets of the main body 2, thus reducing the time spent by subsequent workers cleaning the debris accumulated inside the multiple feed inlets of the main body 2 and improving the practicality of the device. By pushing the fixing plate 403, the two sets of sliding plates 401 are moved out of the two sets of slots in the positioning frame 1, so that the subsequent cleaning mechanism 4 can be removed from the top of the positioning frame 1, thereby minimizing the possibility that the cleaning mechanism 4 will block the feed end of the main body 2 during subsequent use.

[0033] The upper surface of the positioning frame 1 is provided with a U-shaped slot, and a U-shaped limiting plate 5 is engaged inside the U-shaped slot of the positioning frame 1. Specifically, by pushing the U-shaped limiting plate 5, the U-shaped limiting plate 5 is inserted into the U-shaped slot of the positioning frame 1, so that the U-shaped limiting plate 5 restricts the movement of the raw material accumulated on the upper end of the coarse grate body 2, thereby minimizing the rolling off of the raw material accumulated on the upper end of the coarse grate body 2.

[0034] A fixing rod 8 is installed on the back of the positioning frame 1. The fixing rod 8 is located on the moving path of the two sets of sliding plates 401. Specifically, by positioning the fixing rod 8 on the moving path of the two sets of sliding plates 401, when the subsequent workers push the two sets of sliding plates 401 to abut the back of the two sets of sliding plates 401 against the front of the fixing rod 8, the positions of the multiple sets of cleaning blocks 405 are respectively located at the top of the multiple sets of feed inlets inside the positioning frame 1. This allows the subsequent workers to quickly adjust and move the multiple sets of cleaning blocks 405 to the top of the multiple sets of feed inlets inside the positioning frame 1, thereby shortening the time and labor spent by the subsequent workers in installing the cleaning mechanism 4, thus improving the practicality of the device.

[0035] The detection mechanism 7 includes a U-shaped connecting plate 701 and an acrylic plate 707. The U-shaped connecting plate 701 is installed on the upper surface of the positioning frame 1. A motor 702 is installed on the right side of the U-shaped connecting plate 701. An alarm 703 is installed on the front of the U-shaped connecting plate 701. Through holes are opened on the inner walls of both sides of the U-shaped connecting plate 701. A lead screw 704 is rotatably connected inside the two sets of through holes of the U-shaped connecting plate 701. A slider 705 is threadedly connected to the outside of the lead screw 704. An infrared sensor 706 is installed on the upper surface of the slider 705. A slot is opened on the front of the U-shaped limiting plate 5. The acrylic plate 707 is installed inside the slot of the U-shaped limiting plate 5. The position of the acrylic plate 707 is located on the signal source path of the infrared sensor 706. The infrared sensor 706 and the control terminal of the alarm 703 are electrically connected.

[0036] Specific method: The starting motor 702 and infrared sensor 706 drive the infrared sensor 706 to move left and right at the upper end of the U-shaped connecting plate 701. The acrylic plate 707 is made of transparent material, so the laser generated by the infrared sensor 706 can illuminate the inside of the U-shaped limiting plate 5. When a large amount of material accumulates inside the U-shaped limiting plate 5, the infrared sensor 706 is triggered to activate the alarm 703. During the activation process, the alarm 703 sounds an alarm to remind the staff to clean the material accumulated on the upper end of the coarse grate body 2 in time, thereby avoiding the blockage caused by the accumulation of a large amount of material on the upper end of the coarse grate body 2. This improves the practicality of the device.

[0037] The protective mechanism 9 includes two sets of side plates 901, both of which are mounted on the upper surface of the slider 705. A top plate 902 is mounted on the upper surface of the two sets of side plates 901, and the top plate 902 is located directly above the infrared sensor 706. Specifically, by positioning the top plate 902 directly above the infrared sensor 706, the protective mechanism 9 shields and protects the infrared sensor 706, thereby minimizing the impact of subsequent raw materials on the infrared sensor 706 and preventing damage to it. This improves the service life of the infrared sensor 706.

[0038] The limiting mechanism 3 includes two sets of L-shaped fixing plates 301, which are respectively installed on the left and right sides of the positioning frame 1. Threaded holes are provided on opposite sides of both sets of L-shaped fixing plates 301, and screws 302 are connected to the internal threads of both sets of L-shaped fixing plates 301. Vacuum suction cups 303 are installed at adjacent ends of both sets of screws 302. Specifically, after the subsequent coarse grate body 2 is engaged inside the magnetic separator inlet, it is pushed by rotating the two sets of screws 302. Two sets of vacuum suction cups 303 are moved, and the adjacent sides of the two sets of vacuum suction cups 303 are respectively abutted against the left and right sides of the magnetic separator inlet. Then, by rotating the subsequent two sets of vacuum suction cups 303, the adjacent sides of the two sets of vacuum suction cups 303 are respectively adsorbed to the left and right sides of the magnetic separator inlet. This allows the subsequent limiting mechanism 3 to restrict the movement position of the trough-cut coarse grate body 2 inside the magnetic separator inlet, thereby improving the stability of the subsequent trough-cut coarse grate body 2 during use.

[0039] The upper surface of the L-shaped connecting plate 402 has two sets of grooves. Limiting rods 6 are slidably connected inside the two sets of grooves of the L-shaped connecting plate 402. The lower surfaces of the two sets of limiting rods 6 are installed on the upper surface of the fixing plate 403. Specifically, when the fixing plate 403 moves up and down, it simultaneously pulls the two sets of limiting rods 6 to slide inside the two sets of grooves of the L-shaped connecting plate 402. This restricts the movement path of the fixing plate 403 during the up and down movement inside the L-shaped connecting plate 402, thereby minimizing the risk of bending of the electric telescopic rod 404 during use and thus improving the service life of the electric telescopic rod 404.

[0040] In this embodiment, by pushing two sets of sliding plates 401 to connect them to the two sets of slots in the positioning frame 1, the positions of the subsequent multiple sets of cleaning blocks 405 are respectively located at the top of the multiple sets of feed inlets inside the positioning frame 1. Then, by activating the electric telescopic rod 404 to push the fixing plate 403, the multiple sets of cleaning blocks 405 move downwards. As the subsequent multiple sets of cleaning blocks 405 move downwards, they push away the debris accumulated inside the multiple sets of feed inlets of the coarse grate body 2, thereby shortening the time spent by the workers to clean the debris accumulated inside the multiple sets of feed inlets of the coarse grate body 2. By pushing the U-shaped limiting plate 5 to insert it into the U-shaped slot in the positioning frame 1, the U-shaped limiting plate 5 restricts the movement of the raw material accumulated on the upper end of the coarse grate body 2, thereby minimizing the rolling of the raw material accumulated on the upper end of the coarse grate body 2.

[0041] Simultaneously, by starting the motor 702 and the infrared sensor 706, the infrared sensor 706 moves left and right at the upper end of the U-shaped connecting plate 701. Since the acrylic plate 707 is made of transparent material, the laser generated by the infrared sensor 706 can illuminate the interior of the U-shaped limiting plate 5. When a large amount of material accumulates inside the U-shaped limiting plate 5, the infrared sensor 706 is triggered to activate the alarm 703. During activation, the alarm 703 sounds an alarm to alert workers to promptly remove the material accumulated on the upper end of the coarse grate body 2. The cleaning process is carried out to minimize the accumulation of raw materials on the upper part of the subsequent coarse grate body 2, which could cause blockage inside the subsequent coarse grate body 2. By rotating the two sets of screws 302, the two sets of vacuum suction cups 303 are moved, and the adjacent sides of the two sets of vacuum suction cups 303 are respectively placed against the left and right sides of the magnetic separator inlet. Then, by rotating the subsequent two sets of vacuum suction cups 303, the adjacent sides of the two sets of vacuum suction cups 303 are respectively adsorbed to the left and right sides of the magnetic separator inlet, so that the subsequent limiting mechanism 3 restricts the movement position of the coarse grate body 2 inside the magnetic separator inlet.

[0042] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed, and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art.
