Cyclone mineral flotation defoaming device

Abstract

The invention discloses a cyclone type mineral flotation defoaming device, which comprises a flotation machine, a foam feeding hopper, a primary cyclone separator, an exhaust fan, a secondary cyclone separator, an exhaust pipe, a screw conveyor and a settling tank. The flotation machine is connected to the foam hopper, the foam hopper is connected to the exhaust fan through the primary cyclone separator, the exhaust fan is connected to the secondary cyclone separator, the top of the secondary cyclone separator is connected to the exhaust pipe, the primary cyclone separator and the secondary cyclone separator The discharge pipes at the bottom of the cyclone separator are all connected to the screw conveyor, and the discharge port of the screw conveyor is connected to the settling tank. The structure of the invention is simple and reliable, the defoaming speed is fast, and it is convenient to realize continuous operation; the two-stage cyclone separation is connected in series to separate the foam and the air, which is high-speed and efficient; no foam breaking agent is used, and the supernatant of the settling tank is recycled, which can reduce emissions and save chemicals and water consumption; system cleaning and dredging is convenient.

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
