Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of mineral processing equipment, and particularly relates to a magnetic separation device for river sand rough selection. BACKGROUND

[0002] The river sand magnetic separator mainly utilizes the principle that magnetic substances are subjected to magnetic force in a magnetic field. When the river sand is conveyed to the magnetic field area of the magnetic separator, the magnetic particles therein are attracted by the magnetic field and are adsorbed on the surface of the drum of the magnetic separator. The non-magnetic particles are separated from the magnetic particles under the action of gravity and other mechanical forces.

[0003] In the prior art, the river sand is mixed with water into a slurry and then enters the interior of the magnetic separator. The magnetic substances move under the action of the magnetic field and are attached to the outer surface of the drum. Then, the magnetic substances are scraped off or washed off by the scraper or water flow. Since the gap between the drum and the shell of the magnetic separator is small, only the slurry with small particles can pass through. However, the river sand contains many large particles, and the flow rate is high, so the river sand is easily accumulated and blocked at the inlet or interior of the magnetic separator, thereby reducing the operating efficiency of the magnetic separator.

[0004] For the problems in the related art, no effective solution has been proposed so far. CONTENT OF THE UTILITY MODEL

DETAILED DESCRIPTION

[0031] With reference to the accompanying drawings, the technical solutions in the embodiments of the utility model will be clearly and completely described below, obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work belong to the scope of the utility model protection.

[0032] In the description of the utility model, it needs to be understood that the terms '' opening '', '' upper '', '' lower '', '' top '', '' middle '', '' inner '' and the like indicate the orientation or positional relationship, only for the convenience of describing the utility model and simplifying the description, and not indicate or imply that the indicated components or elements must have a particular orientation, be constructed and operated in a particular orientation, therefore, it cannot be understood as the limitation of the utility model.

[0033] Please refer to Figures 1-6 The utility model discloses a magnetic separation device for river sand rough selection, including magnetic separation machine body 1:

[0034] Magnetic separation machine body 1 is provided with drive assembly 2, connecting assembly 3, discharging assembly 4 and limiting component 5 respectively;

[0035] The output end of drive assembly 2 is fixedly installed with one end of connecting assembly 3, so that drive assembly 2 drives connecting assembly 3 to operate;

[0036] One end of discharging assembly 4 is fixedly installed with one end of connecting assembly 3, so that connecting assembly 3 drives discharging assembly 4 to discharge uniformly when operating;

[0037] The inside of limiting component 5 is rotatably connected with one end of discharging assembly 4, so that limiting component 5 limits and fixes the position of discharging assembly 4.

[0038] It needs to be explained that after the ore pulp flows into the magnetic separator through the ore feeding box, the ore particles enter the ore feeding area of the tank in a loose state under the action of the water flow of the ore feeding water pipe. Under the action of the magnetic field, the magnetic particles form " magnetic group " or " magnetic chain " by magnetic aggregation. The " magnetic group " or " magnetic chain " moves towards the magnetic pole under the action of the magnetic force in the ore pulp, and is adsorbed on the roller. Because the polarity of the magnetic pole is alternately arranged along the rotation direction of the roller, and the magnetic pole is fixed during operation, when the " magnetic group " or " magnetic chain " rotates with the roller, the magnetic stirring phenomenon occurs, and the gangue and other non-magnetic minerals mixed in the " magnetic group " or " magnetic chain " fall off in the tumbling. The concentrate is turned to the weakest place of the magnetic system at the edge of the cylinder, and is discharged into the concentrate tank under the action of the washing water flow of the ore discharging water pipe. The non-magnetic or weak-magnetic minerals are left in the ore pulp and discharged out of the tank, which is tailings.
