Description

Technical Field

[0001] This utility model relates to the field of permanent magnet separator technology, and in particular to a permanent magnet separator with explosion-proof function. Background Technology

[0002] Permanent magnet separators utilize the property of magnets to attract ferrous materials, achieving iron removal within an effective range. Internally, they employ a composite magnetic system composed of neodymium iron boron (NdFeB) and other special permanent magnets with high coercivity and remanence. They offer advantages such as maintenance-free operation, strong magnetic force, long lifespan, simple installation, convenient use, and reliable operation. Suitable for removing iron from non-magnetic materials on belt conveyors, vibrating conveyors, electromagnetic vibrating feeders, plate separators, and discharge chutes. They can remove ferromagnetic substances weighing from 0.1 to 35 kg, and the internal permanent magnet system has a service life of over 10 years.

[0003] In traditional explosion-proof designs for permanent magnet separators, fixed protective covers are typically used. However, this fixed installation method often makes replacement particularly cumbersome. Each time the protective cover needs to be replaced, the disassembly process is both time-consuming and labor-intensive, leading to extended equipment downtime and impacting overall production efficiency. Therefore, there is an urgent need for a permanent magnet separator with explosion-proof capabilities to solve these problems. Utility Model Content

An explosion-proof protective mechanism for the permanent magnet separator plate is located on the bottom of the inner wall of the fixed frame. The protective mechanism includes first trapezoidal grooves on both sides of the bottom of the inner wall of the fixed frame. First trapezoidal sliders slide inside the two first trapezoidal grooves. The bottom of the two first trapezoidal sliders is fixed to the top of the same protective cover. One end of the protective cover is rotatably connected to a maintenance door. Two fixing blocks are fixed to the side of the protective cover. The end of each fixing block near the maintenance door is rotatably connected to a limit plate via a torsion spring.

[0023] The protective mechanism includes first trapezoidal grooves 306 on the bottom of both sides of the inner wall of the fixed frame 3. First trapezoidal sliders 405 are slidably arranged inside the two first trapezoidal grooves 306. The top of the same protective cover 401 is fixed to the bottom of the two first trapezoidal sliders 405. One end of the protective cover 401 is rotatably connected to an inspection door 4. Two fixing blocks 402 are fixed to the side of the protective cover 401. The end of the fixing block 402 near the inspection door 4 is rotatably connected to a limit plate 403 through a torsion spring. Two stops 404 are fixed to one end of the inspection door 4, and the two stops 404 cooperate with the limit plate 403 respectively. The inspection door 4 and the protective cover 401 can prevent the permanent magnet iron removal plate 303 from exploding and protect the surrounding area. The protective cover 401 can be quickly disassembled through the first trapezoidal sliders 405, and the permanent magnet iron removal plate 303 can be easily inspected through the inspection door 4.

[0024] In this utility model, a rotating plate 304 is rotatably connected to both sides of one end of the fixing frame 3, and a threaded hole 406 is opened at one end of each of the two first trapezoidal sliders 405. The threaded hole 406 is provided with a suitable screw 305 inside, and holes for the screw 305 to pass through are opened at both ends of the bottom of the rotating plate 304.

[0025] In this utility model, non-magnetic isolation plates 407 are fixed to the bottom of both sides of the inner wall of the protective cover 401.

[0026] In this utility model, the bottom sides of the protective cover 401 are provided with second trapezoidal grooves 408, and the interior of the two second trapezoidal grooves 408 is provided with second trapezoidal sliders 501. The bottom of the two second trapezoidal sliders 501 is fixed with the same magnetic object collection box 5. One end of the magnetic object collection box 5 is fixed with a handle 502. The magnetic object collection box 5 can collect some magnetic items.

[0027] In this utility model, electric telescopic rods 301 are installed on both sides of the top of the fixed frame 3, and the output shafts of the two electric telescopic rods 301 pass through the top of the fixed frame 3 and are fixed to the top two ends of the permanent magnet iron removal plate 303.

[0028] In this utility model, the conveying mechanism includes rotating rods 201 that are rotatably connected to both ends of the inner wall of the mounting frame 1, and the outer walls of the two rotating rods 201 are provided with matching conveyor belts 2.

[0029] In this utility model, a motor 202 is installed on one side of the mounting bracket 1, and the output shaft of the motor 202 is fixedly connected to one end of one of the rotating rods 201.

[0030] Working principle: In use, firstly, remove the magnetic material collection box 5 from the bottom of the protective cover 401 using the handle 502. Then, drive the motor 202 to rotate the rotating rod 201, which in turn drives the conveyor belt 2 to rotate and transport the material. Then, use the two electric telescopic rods 301 to move the permanent magnet iron removal plate 303 down and close to the top of the non-magnetic isolation plate 407. The permanent magnet iron removal plate 303 then removes iron from the material, adsorbing magnetic items in the material to the bottom of the non-magnetic isolation plate 407. When a certain amount has been collected, align the second trapezoidal slider 501 with the inside of the second trapezoidal groove 408 and insert it. Move the magnetic material collection box 5 below the non-magnetic isolation plate 407. Then, drive the electric telescopic rods 301 to move the permanent magnet iron removal plate 303 to the top of the fixed frame 3 and away from it. With the non-magnetic isolation plate 407 in place, the distance between the permanent magnet iron removal plate 303 and the non-magnetic isolation plate 407 increases, reducing the magnetic attraction of the permanent magnet iron removal plate 303 to magnetic items. The magnetic items then fall into the magnetic collection box 5 under their own weight for collection. At this time, the inspection door 4 and the protective cover 401 provide explosion-proof protection for the permanent magnet iron removal plate 303. Rotating the limit plate 403 away from the stop block 404 allows the inspection door 4 to be opened, facilitating the inspection of the permanent magnet iron removal plate 303. When the entire protective cover 401 needs to be replaced, rotating the screw 305 away from the threaded hole 406 and opening the inspection door 4 allows the entire protective cover 401 to be pulled out and moved away from the fixing frame 3, enabling replacement or repair of the protective cover 401. This achieves rapid disassembly of the protective cover 401, reducing downtime and improving work efficiency.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
