Rotor cyclone two-stage tandem type mineral flotation and defoaming device

Abstract

The invention discloses a rotor cyclone two-stage tandem type mineral flotation and defoaming device which comprises a flotation machine, a foam feeding hopper, a rotor, an exhaust fan, a cyclone separation device, an exhaust pipe, a spiral conveyor and a sedimentation pond. The rotor is located in a barrel and composed of a rotary shaft and blades, and a barrel discharging pipe is connected with the spiral conveyor. The flotation machine is connected with the foam feeding hopper, the foam feeding hopper is connected with the exhaust fan through the barrel, the exhaust fan is connected with the cyclone separation device, the top of the cyclone separation device is connected with the exhaust pipe, the bottom of the cyclone separation device is connected with the spiral conveyor through a discharging pipe, and a material outlet of the spiral conveyor is connected with the sedimentation pond. The rotor cyclone two-stage tandem type mineral flotation and defoaming device is simple and reliable in cyclone separation and high in rotor defoaming efficiency, facilitates continuity achievement, rapidly and efficiently performs defoaming and air separation in a rotor cyclone two-stage tandem mode, does not use a defoaming agent, recycles supernate in the sedimentation pond, can reduce discharge and save agent and water consumption and is systematically quick and convenient to clean, clear and dredge.

Description

technical field [0001] The invention relates to a rotor cyclone two-stage serial mineral flotation defoaming device. The defoaming device is designed according to the working principle of the rotor and the cyclone separator. Background technique [0002] Flotation is a method of sorting according to the difference in the surface physical and chemical properties of mineral particles and the difference in mineral floatability. Most ores can be sorted by flotation, such as coal, coal fluorite, talc and other non-metallic ores, especially for lead, zinc, molybdenum, mercury, copper and other metals and oxidized ores. [0003] Flotation is a beneficiation method based on the different wettability of minerals by water. The purpose is to make minerals selectively adhere to the foam produced by air, chemicals and water and float up to achieve separation. After the flotation is completed, post-processing is required, mainly defoaming and sedimentation separation of minerals to meet ...

Problems solved by technology

[0004] The commonly used defoaming method is mainly to store the natural defoaming in the pool, and use the method of adding water and defoaming agent to defoam, but this method needs to consume a lot of water, and due to the discharge of a large amount of flotation agent and defoaming agent, it is harmful to the environment. caused serious pollution
