Abstract
Description
Technical Field
[0001] This utility model relates to a magnetic material production and processing equipment, specifically a flotation device for ultra-high purity concentrate powder. Background Technology
[0002] The production of magnetic materials involves turning magnetic materials into powder, adding a coagulant, pressing and molding the powder, and then sintering it into a hard state. To improve the physical properties of magnetic materials, finer powder is required. Magnetic materials obtained by conventional grinding methods and then sintered have more pores and weaker structural strength, making them unsuitable for high-pressure working environments. Therefore, the powder needs to be processed with greater fineness to meet the product's property requirements and improve its quality. Utility Model Content
[0003] The purpose of this invention is to overcome the above-mentioned deficiencies in the existing technology and to provide a flotation device for ultra-high purity concentrate powder.
[0004] The technical solution adopted by this utility model to solve the above problems is as follows: The flotation device includes a hopper, a ball mill, a mixing tank, and a flotation machine. The hopper is connected to the feed inlet of the ball mill, and the mineral powder enters the ball mill through the hopper. The other end of the ball mill is set as the discharge outlet, and a spiral elevator separator is set at the discharge outlet. The upper end of the spiral elevator separator is set as the concentrate outlet and is connected to the mixing tank. The bottom of the spiral elevator separator is set as the tailings outlet, and the tailings outlet is connected to the feed inlet of the ball mill through a return pipe. The outlet in the mixing tank is connected to the flotation machine. The upper part of the flotation machine is the flotation feed port, and the concentrate enters the conveying channel through the flotation feed port. A tailings outlet is also set at the bottom of the flotation machine and is connected to the return pipe. The flotation unit is a linked operating device. The feed hopper adds the finely crushed raw material to the ball mill. In the ball mill, the mineral powder is mixed with water and repeatedly ground to achieve the required high fineness. The slurry after ball milling is then separated by a spiral conveyor separator. Particles that meet the required size can be easily lifted and conveyed to the mixing tank. Particles that cannot be lifted are not fine enough and are returned to the ball mill through the return pipe for further grinding. Foaming agents can be added to the slurry in the mixing tank and thoroughly mixed with the slurry before entering the flotation machine. The slurry is thoroughly agitated and foams in the flotation machine. The finer particles rise to the top of the liquid with the foam and are separated by the flotation process. The heavier tailings are returned to the ball mill for further grinding, resulting in ultra-high purity fine mineral powder materials that meet the requirements of the production product.
[0005] Furthermore, the ball mill's feed inlet is connected to a feeding trough, which is also connected to a discharge hopper, a return pipe, and a water pipe. The mineral powder in the discharge hopper enters the ball mill along with water transported by the water pipe. Tailings transported by the return pipe flow into the feeding trough and also into the ball mill. The feeding trough, located before the ball mill, facilitates control of the proportions of materials from various sources, prevents excessively high material density during secondary grinding, facilitates mixing, and allows for easy addition of water before grinding, enabling precise control of the water ratio and facilitating production.
[0006] Furthermore, the inlet of the spiral elevator separator is located at a low position and connected to the outlet of the ball mill, while the outlet of the spiral elevator separator is located at a high position. The spiral blades rotate upwards from the bottom, driving the mineral powder slurry upwards. The spiral elevator mainly relies on the agitation of the spiral blades; lighter materials are easier to lift, while heavier materials are recovered through the return pipe and further processed when there is a large quantity.
[0007] Furthermore, the inlet of the mixing tank is lower than the outlet, a stirring blade is provided in the middle of the mixing tank, and the upper part of the mixing tank is set as an open surface. Foaming agent is added to the mixing tank from the open surface, and the rotating blades mix the foaming agent and mineral powder slurry evenly. The upper part of the mixing tank is open, which facilitates feeding and controls the amount processed in each batch. The outlet is relatively high, and the slurry only leaves due to fluid dynamics after it has been fully mixed, thus promoting mixing.
[0008] Furthermore, the flotation machine is equipped with an agitation device. A pulsator blade is located at the bottom of the agitation device, which is fitted with a hollow tube. Liquid has liquid holes on the side of the hollow tube. Liquid enters from the lower end of the hollow tube and exits through the side liquid holes. The height of the liquid holes is located in the upper layer of the liquid within the flotation machine, but below the height of the flotation feed inlet. A discharge port is located at the bottom of the flotation machine, corresponding to the bottom layer of the liquid. The pulsator blades can agitate and shape the liquid, primarily by feeding it into the hollow tube and discharging it through the liquid holes. During this process, the liquid comes into contact with air, accelerating foaming efficiency and allowing the finer particles to quickly combine with the foam, thus increasing production efficiency.
[0009] Compared with the prior art, this utility model has the following advantages and effects: This design is an improvement of the processing equipment for producing magnetic materials, which can obtain ultra-high purity concentrate powder, is suitable for producing products with high physical property requirements, produces magnetic materials with high density, is suitable for high pressure environment, and can realize mass production.
