TECHNICAL FIELD

[0001] The utility model belongs to ore processing pretreatment technical field, concretely relates to an ore processing pretreatment device. BACKGROUND

[0002] Ore processing pretreatment refers to a series of initial treatment processes of ore before processing or extracting useful minerals, which aims to improve the properties of ore through physical methods, improve the efficiency and benefit of subsequent crushing, grinding and other links;

[0003] The existing ore processing pretreatment device mostly adopts split type layout, relies on external equipment to process ore first, and then sends to the main processing machinery, which undoubtedly prolongs the operation link, causes the processing time limit to decline, and limits the overall pretreatment process efficiency. UTILITY MODEL CONTENT

[0004] Therefore, the utility model provides an ore processing pretreatment device, which can simplify the processing steps through the integrated design of magnetic separation and ore processing device, significantly enhance the overall efficiency of ore processing, and ensure the efficient execution of ore pretreatment.

[0005] To solve the above technical problems, the utility model provides an ore processing pretreatment device, which comprises a machine body and a magnetic separation roller symmetrically connected to the upper end of the inner cavity of the machine body, a reverse tapered guide plate is arranged above the magnetic separation roller close to the inner cavity of the machine body, the magnetic separation roller is arranged on the lower end of the reverse tapered guide plate on both sides, that is, the magnetic separation roller is started and synchronously reversely rotated to realize the magnetic separation of ore, and the ore after magnetic separation falls into the lower process.

[0006] A discharge hopper is arranged below the two magnetic separation rollers, one end of the discharge hopper penetrates the machine body and extends to the outside, scrapers are arranged on the upper end of the discharge hopper on both sides, the ends of the scrapers are respectively in contact with the outer part of the magnetic separation roller on the same side, that is, the scraper will continuously scrape the magnetic material adsorbed on the surface of the magnetic separation roller, so that the magnetic material falls into the discharge hopper, thereby keeping the surface of the magnetic separation roller clean and ensuring continuous and efficient magnetic separation.

[0007] The two side walls of the inner cavity of the machine body close to the reverse tapered guide plate are provided with guide blocks, that is, the guide blocks cooperate with the reverse tapered guide plate to improve the effect of guiding the material.

[0008] It also includes a driving mechanism, which is used to drive the two magnetic separation rollers to rotate in opposite directions at the same amplitude at the same time. The driving mechanism includes a motor arranged at one end of the machine body, and the output shaft of the motor is fixedly connected to one end of a magnetic separation roller. The two magnetic separation rollers are provided with gears at the ends away from the motor, and the two gears are meshed with each other. That is, when the motor is started, the motor drives the magnetic separation roller fixedly connected to it to rotate, and through the two meshed gears, the two magnetic separation rollers can rotate in opposite directions at the same amplitude at the same time.

[0009] It also includes a dispersion component, which is used to evenly disperse the mineral material. The dispersion component includes rotating rods that are respectively connected to the inner cavity of the machine body near both sides of the inverted cone guide plate.

[0013] 1. The ore enters from the upper end of the machine body, and then is guided by the inverted cone-shaped guide plate and the guide block to guide the ore to fall naturally close to each magnetic separation roller. During this process, the magnetic separation roller and the motor are started, and the motor drives the magnetic separation roller fixedly connected to it to rotate, and drives the other magnetic separation roller to rotate synchronously in the opposite direction through two meshing gears. When the ore passes through the two magnetic separation rollers, the non-magnetic material continues to fall, while the magnetic material is attracted and retained on the roller surface of the magnetic separation roller. As the magnetic separation roller rotates, the scraper will continuously scrape off the magnetic material adsorbed on the surface of the magnetic separation roller and make it fall into the discharge hopper, thereby keeping the surface of the magnetic separation roller clean and ensuring continuous and efficient magnetic separation. The ore after magnetic separation falls into the lower process. The integrated design of magnetic separation and ore processing equipment simplifies the processing steps, significantly enhances the overall efficiency of ore processing, and ensures the high efficiency of ore pretreatment.
