Description

Technical Field

[0001] The utility model relates to the technical field of magnetic separation devices, in particular to a novel magnetic separation device with good magnetic separation effect. Background Art

[0002] A magnetic separator is a device that uses the physical properties of magnetic materials to separate or extract substances. It is usually used to separate or extract mixtures containing magnetic components, such as extracting iron ore from ore. Magnetic separators are widely used in mining, metallurgy, building materials and other industries.

[0003] Existing magnetic separators usually consist of a magnetic system and a conveying system. The magnetic system includes components such as a magnetic drum and a magnetic separation zone, and uses a strong magnetic field to absorb or repel the magnetic components in the material. The conveying system is used to feed the mixture into the magnetic system and discharge the separated material from the magnetic system.

[0004] However, when using existing magnetic separators to separate metal powders contained in mineral soil or mud, due to the presence of agglomerates in the mineral soil or mud, the agglomerated mineral soil or mud is not easy to loosen and break when passing through the magnetic separator, and the metal powders wrapped in the agglomerates cannot be normally magnetically attracted and are discharged along with the agglomerates, resulting in poor magnetic separation effect. Utility Model Content

[0005] The purpose of the utility model is to provide a novel magnetic separation device with good magnetic separation effect to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions.

[0007] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion.

[0008] It can be seen that since the entire magnetic separation device is arranged vertically, the mineral soil or silt is transported downward by gravity, and there is a downward impact effect, which can disperse some of the agglomerated mineral soil or silt, thereby improving the magnetic separation effect on metal powders. In addition, when the shaft rotates, it drives the mounting plate to rotate synchronously, and the sleeve will intermittently contact the arc-shaped protrusion on the mounting plate. The arc-shaped protrusion pushes the sleeve and the discharge plate upward. As the rotation continues, the discharge plate swings back and forth up and down at a high frequency, so that the mineral soil or silt can be shaken evenly, and the agglomerates can also be shaken off, further ensuring the magnetic separation effect on metal powders.

[0009] Furthermore, both frames are provided with vertically extending sliding grooves, in which sliding seats are respectively installed for limited sliding, and the scraper is installed between the two sliding seats. One side of the frame is provided with an adjustment mechanism for driving the scraper to move vertically and adjust.

[0010] When the top of the scraper is excessively worn and the gap between it and the magnetic separation roller is too large, the scraper can be pushed upward by operating the adjustment mechanism to reduce the gap between the scraper and the magnetic separation roller to ensure the scraping effect on the metal powder.

[0011] Furthermore, the driving mechanism includes a mounting base, a driving motor, a first pulley, a second pulley and a transmission belt. The driving motor is fixed to the side of the frame through the mounting base, the first pulley is fixed to the output shaft of the driving motor, the second pulley is fixedly sleeved on one end of the shaft, and the transmission belt is sleeved on the first pulley and the second pulley.

[0012] The driving motor drives the first pulley to rotate. The rotating first pulley can drive the second pulley to rotate under the transmission action of the transmission belt, and then drives the shaft rod and the magnetic separation roller to rotate, providing a stable drive for the rotation of the shaft rod.

[0013] Furthermore, the adjustment mechanism includes an adjustment plate, an adjustment screw and a connecting block. The adjustment plate is fixed to the side of the frame. A vertical threaded hole is provided on the adjustment plate. The adjustment screw is thread-matched and installed in the threaded hole. The connecting block is rotatably installed on the top of the adjustment screw. The connecting block is fixedly connected to the side of the sliding seat on one side.

[0014] By rotating the adjusting screw, the adjusting screw moves upward, thereby pushing the connecting block and the sliding seat on one side to move upward, so that the scraper can be adjusted upward to reduce the gap between the scraper and the magnetic separation roller to prevent metal powder from passing between the scraper and the magnetic separation roller.

[0015] Furthermore, a pinch handle is fixed to the bottom end of the adjusting screw rod, and the outside of the pinch handle is provided with anti-slip grooves.

[0016] By holding the handle, it is convenient to exert force to turn the adjusting screw, and the anti-slip grooves are provided on the handle to increase the friction between the hand and avoid slipping when twisting.

[0017] Furthermore, side baffles are respectively fixed on both sides of the upper surface of the blanking plate, and the side baffles extend along the blanking direction of the blanking plate.

[0018] The side baffles are used to block the conveying of ore soil or silt on the unloading plate to prevent the ore soil or silt from rolling down from the side of the unloading plate.

[0019] Furthermore, a conveying trough plate is arranged obliquely between the two frames, and the conveying trough plate is located below the scraper. One side of the frame is provided with a clearance opening with two sides passing through the clearance opening, and one end of the conveying trough plate extends to the outer side of the frame through the clearance opening.

[0020] The metal powder scraped off by the scraper falls down onto the conveying trough plate, and the metal powder can be transported to the outside through the conveying trough plate for easy collection.

[0021] Furthermore, the width of the discharge hopper is smaller than that of the discharge plate, the width of the discharge plate is smaller than that of the magnetic separation roller, and the width of the separation plate is larger than that of the magnetic separation roller.

[0022] The width of the unloading plate is sufficient to cover the unloading hopper, the width of the magnetic separation roller is sufficient to cover the unloading plate, and the width of the separation plate is sufficient to cover the magnetic separation roller, so as to prevent the mineral soil or silt from leaking from the sides of the unloading plate and the magnetic separation roller during the transportation process.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows.

[0024] 1. In the utility model, since the entire magnetic separation device is arranged vertically, the ore soil or silt is transported downward by gravity, which has a downward impact effect, and can disperse part of the agglomerated ore soil or silt, thereby improving the magnetic separation effect on metal powder.

[0025] 2. When the shaft of the utility model rotates, the mounting plate is driven to rotate synchronously, and the sleeve will intermittently contact the arc-shaped protrusion on the mounting plate. The arc-shaped protrusion pushes the sleeve and the unloading plate upward. As the rotation continues, the unloading plate swings back and forth up and down at a high frequency, thereby shaking the mineral soil or mud evenly and also shaking off the agglomerates, further ensuring the magnetic separation effect on metal powder.

[0026] 3. When the top of the scraper is excessively worn and the gap between it and the magnetic separation roller is too large, the utility model can adjust the scraper upward by screwing the adjusting screw to push the connecting block and the sliding seat on one side to move upward, so as to reduce the gap between the scraper and the magnetic separation roller, thereby preventing metal powder from passing through between the scraper and the magnetic separation roller, thereby ensuring the scraping effect of the metal powder.
