Description

TECHNICAL FIELD

[0001] The utility model relates to ore magnetic separation technical field, concretely is a kind of dry type drum type ore magnetic separator. BACKGROUND

[0002] Ore is the cornerstone of modern industry and infrastructure, but a large amount of waste rock or tailings containing magnetic minerals will be generated during mining and processing. In order to efficiently utilize these resources, magnetic separation technology needs to be used for separation, and the dry type drum type ore magnetic separator utilizes magnetic force to separate magnetic minerals from non-magnetic minerals in the ore through the strong magnetic field generated by the permanent magnetic drum. Magnetic force is a natural force that can generate a magnetic field in space. When the ore enters the magnetic field, minerals with different magnetic properties experience different magnetic forces in different directions, thereby achieving separation.

[0003] According to the dry type drum type permanent magnetic separator (authorized announcement CN 220678170U) disclosed by the patent network, "a dry type drum type permanent magnetic separator, comprising a drum magnetic separator, the bottom four corners of the drum magnetic separator are provided with foot supports, two foot supports are connected through a transmission shaft, the transmission shaft is wrapped with a conveyor belt, the transmission shaft is connected with a second motor through the foot support, the outer side of the second motor is provided with a second fixed rack, the inner side of the conveyor belt is provided with a second shaft at one end, and the two ends of the second shaft are movably connected with the foot support."

[0004] According to the above description, the applicant believes that the following problems exist:

[0005] In the use process of the utility model, ore raw materials are added to the conveyor belt from the ore adding port. At the top of the drum magnetic separator, baffles are arranged on both sides of the conveyor belt to prevent ore from falling. The permanent magnetic force drum rotates to adsorb the magnetic ore in the ore conveyed above the conveyor belt. Finally, the third motor is started, and the rotating scraper is driven to rotate by the third motor. The scraper on the rotating scraper will scrape the magnetic ore adsorbed on the permanent magnetic force drum, but in the actual use process, when the device adds ore raw materials to the ore adding port, it cannot control the feeding speed and feeding amount because the ore raw materials are directly added to the ore adding port. This causes excessive accumulation of materials in the magnetic separator during continuous feeding, affecting the effective separation of magnetic minerals and non-magnetic minerals, and thus the processing capacity of the magnetic separator reaches the limit, affecting the separation effect. Therefore, it is necessary to improve the dry type drum type ore magnetic separator. UTILITY MODEL CONTENTS
