Description

Technical Field

[0002] Iron removers are widely used in metallurgy, mining, coal preparation plants, power plants, ceramics, glass, cement, building materials, chemicals, and food and feed processing industries. Iron removers are divided into two categories based on the magnetic source: electromagnetic and permanent magnets. There are many types of iron removers, the most common of which is the magnetic drum remover, which can operate continuously in conjunction with a conveyor belt. However, for mixed materials containing a large amount of magnetic material, the magnetic material is adsorbed and fixed within a certain range after entering the magnetic field. Non-magnetic materials may be trapped between the magnetic materials, resulting in a large amount of non-magnetic material mixed with the separated magnetic material. Repeated screening with multiple devices is usually required to achieve the desired separation effect.

[0020] like Figure 1-3 As shown, a dry iron remover includes a mounting frame 11, and the mounting frame 11 is installed with an upper mounting frame 8 and a lower mounting frame 14. The upper mounting frame 8 is located above the lower mounting frame 14, and the upper mounting frame 8 is installed with a lower hopper 7.

[0021] The side wall of the discharge hopper 7 above the discharge port 17 is provided with a movable plate 15, and the movable plate 15 is slidably connected to the discharge hopper 7. Preferably, sliding grooves are provided on both sides of the side wall above the discharge port 17, and the movable plate 15 is slidably connected in the sliding groove. Two corresponding mounting rods 31 are installed between the discharge hopper 7 and the mounting frame 11, and a driving shaft 12 is rotatably connected to the two mounting rods 31. Two racks 16 are fixedly connected to the movable plate 15, and a gear 10 meshing with the two racks 16 is installed on the driving shaft 12. A mounting head 2 is installed at one end of the driving shaft 12, and a rocker 1 is installed on the mounting head 2. By rotating the rocker 1, the driving shaft 12 can be made to rotate, so that the gear 10 drives the rack 16 to rotate, thereby realizing the movement of the movable plate 15. The movement of the movable plate 15 can control the size of the blocking of the discharge port 17 by the movable plate 15, thereby realizing the control of the size of the opening of the discharge port 17, thereby controlling the falling speed of the material.

[0022] Two groups of supporting frames 4 corresponding to each other are installed on the top of the lower mounting frame 14. One group of supporting frames 4 is rotatably connected to a first transmission rod, and the first transmission rod is connected to a magnetic roller 5. The other group of supporting frames 4 is rotatably connected to a second transmission rod, and the second transmission rod is connected to a rotating roller 3. A conveyor belt is installed on the magnetic roller 5 and the rotating roller 3. One end of the first transmission rod is connected to a driving mechanism, which can drive the first transmission rod to rotate, drive the magnetic roller 5 to rotate, and thus rotate the conveyor belt, thereby completing the conveying process of the conveyor belt. The magnetic roller 5 drives the second transmission rod to rotate through the conveyor belt. The second transmission rod rotates, so that no dynamic friction is generated between the conveyor belt and the rotating roller 3, and the service life of the conveyor belt is long.

[0023] The driving mechanism includes a mounting plate, which is fixedly connected to one side of the lower hopper 7 and the mounting frame 11. A motor 19 is installed on the mounting plate. A driving roller is installed at the output end of the motor 19. One end of the first transmission rod is fixedly connected to a rotating roller 3. The rotating roller 3 is connected to the driving roller through a transmission belt. The motor 19 drives the driving roller to rotate, and the driving roller drives the rotating roller 3 to rotate through the transmission belt. A protective cover 20 is provided outside the driving mechanism.

[0024] A discharge hopper 6 is installed at the bottom of the lower mounting frame 14, and a discharge port is provided at the bottom of the discharge hopper 6. Two parallel adjusting rods 26 at the same horizontal height are installed above the discharge hopper 6. Adjustment plates 27 are respectively installed on the two adjusting rods 26. The adjustment plates 27 are bent, and the two adjustment plates 27 are bent outward. The adjustment plates 27 pass through the discharge port, and the bottom of the adjustment plates 27 is located below the discharge port. An adjustment mechanism is installed on the side wall of the discharge hopper 6, and the adjustment mechanism includes a fixed block 23, which is fixedly connected to the side wall of the discharge hopper 6. The fixed block 23 is rotatably connected to the adjusting rod 26. The inclination angle of the adjusting plate 27 can be controlled by rotating the adjusting rod 26. Thereby, the opening angle between the two adjustment plates 27 is controlled to achieve the screening of objects with different magnetic forces; a threaded hole is provided on the side wall of the fixed block 23, and a screw 29 is threadedly connected to the hole on the side wall of the fixed block 23. One end of the screw 29 is in contact with the adjustment rod 26, and a tightening handwheel 28 is installed on the other end of the screw 29. By rotating the tightening handwheel 28, the screw 29 fixes the adjustment rod 26, thereby fixing the adjustment plate 27 in the target position; the end of the adjustment rod 26 away from the fixed block 23 is rotatably connected to the side wall of the lower hopper 7, and the other end of the adjustment rod 26 is installed with an adjusting handwheel 22, which can be used to more easily rotate the adjustment rod 26.

[0025] The upper part of the adjusting plate 27 is provided with a rotating rod 25, and the rotating rod 25 is located above the adjusting rod 26. The end of the adjusting rod 26 away from the fixed block 23 is cooperated with the slide rail 24, and the slide rail 24 is provided with a track, and the track on the slide rail 24 corresponds to the movement trajectory of the adjusting rod 26. The slide rail 24 is fixedly connected to the inner side wall of the lower hopper 7. The end of the rotating rod 25 away from the slide rail 24 is cooperated with to install a limit block 21. The limit block 21 is provided with a limit hole that matches the track of the slide rail 24, and the side wall of the discharge hopper 6 is provided with a hole that matches the limit hole. The limit hole corresponds to the shape of the track of the slide rail 24. The end of the rotating rod 25 away from the slide rail 24 is threadedly connected with a limit head 30 that matches the limit block 21. Rotating the limit head 30 can make the limit head 30 and the limit block 21 tightened, fixing the limit head 30, thereby keeping the rotating rod 25 fixed, making the adjusting plate 27 more stable.

[0026] In summary, in actual practice, the material to be deironed is put into the discharge hopper 7, and then the material falls through the discharge port 17. The size of the discharge port 17 is controlled by the rocker 1 to control the movable plate 15, and the appropriate discharge speed is adjusted. The material falls onto the conveyor belt, and under the action of the magnetic roller 5, the iron-free material is directly thrown out by the conveyor belt, blocked by the baffle 13 or directly falls onto the discharge hopper 6, and then discharged from the discharge port. The iron-containing material in the material is adsorbed by the magnetic roller 5, and when it reaches the bottom of the magnetic roller 5, it is on the conveyor belt. Under the action of the magnetic roller 5, the iron-containing material will break away from the adsorption of the magnetic roller 5 and fall between the two adjustment plates 27. By controlling the size of the openings on the tops of the two adjustment plates 27, it is possible to control the iron content to fall between the two adjustment plates 27. The material with a lower iron content is discharged from the discharge port on the outer side of the two adjustment plates 27, thereby realizing the screening of the material within a certain iron content range. The iron purity range of the screened material is relatively accurate, and no additional screening process is required for screening. It is easy to use and saves equipment costs.
