Cyclone-type mineral floating and defoaming device

Abstract

The invention discloses a cyclone-type mineral floating and defoaming device. The cyclone-type mineral floating and defoaming device comprises a flotation machine, a foam feeding hopper, a primary cyclone separator, an exhaust fan, a secondary cyclone separator, an exhaust pipe, a spiral conveyor and a sedimentation tank, wherein the flotation machine is connected with the foam feeding hopper; the foam feeding hopper is connected with the exhaust fan through the primary cyclone separator; the exhaust fan is connected with the secondary cyclone separator; the top of the secondary cyclone separator is connected with the exhaust pipe; discharging pipes at the bottoms of the primary cyclone separator and the secondary cyclone separator are connected with the spiral conveyor; a discharge opening of the spiral conveyor is connected with the sedimentation tank. The cyclone-type mineral floating and defoaming device is simple and reliable in structure, high in defoaming speed and convenient to implement continuousness; the primary cyclone separator and the secondary cyclone separator are serially connected for defoaming and air separation, at high speed and efficiency; a defoaming agent is not used, and supernatant in the sedimentation tank can be recycled, so that emission is reduced and chemical agent consumption and water consumption are saved; the cyclone-type mineral floating and defoaming device is convenient to clean and dredge.

Description

technical field [0001] The invention relates to a cyclone type mineral flotation defoaming device, which is designed according to the working principle of a 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 the needs of later smelting and processing. [0...

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
