Cyclone type mineral flotation and defoaming device with induced draft fan convenient to disassemble

Abstract

The invention discloses a cyclone type mineral flotation and defoaming device with an induced draft fan convenient to disassemble. The cyclone type mineral flotation and defoaming device is characterized in that a flotation machine is connected with a foam feeding hopper, the foam feeding hopper is connected with the induced draft fan by a primary cyclone separator, secondary cyclone separators are connected with the induced draft fan, an exhaust pipe is connected to the tops of the secondary cyclone separators, discharge pipes at the bottoms of the primary cyclone separator and the secondary cyclone separators are connected with a spiral conveyor, and a discharge outlet of the spiral conveyor is connected with a sedimentation tank; an impeller of the induced draft fan can timely clean dust by the aid of centrifugal force. The cyclone type mineral flotation and defoaming device has the advantages that emission and water consumption can be reduced, chemicals can be saved, the cyclone type mineral flotation and defoaming device is high in defoaming speed, more importantly, disassembling technologies for the induced draft fan are changed to a great extent, accordingly, pressures of components similar to nuts on the end surfaces of shaft shoulders of screws can be easily eliminated when the induced draft fan is disassembled, the problem that an existing induced draft fan assembled in a threaded manner is continuously automatically locked under the effects of load and is difficult to detach can be effectively solved, the cyclone type mineral flotation and defoaming device is particularly applicable to conveniently and quickly detaching large fans after the large fans are locked in a threaded manner, and particularly obvious effects can be realized.

Description

technical field [0001] The invention relates to a cyclone-type mineral flotation defoaming device, in particular to a cyclone-type mineral flotation defoaming device that does not accumulate dust in a fan and is easy to disassemble. 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 ...

AI Technical Summary

Problems solved by technology

In the actual assembly of shafts and holes with transmission threads, in order to achieve large load-bearing functions, the size of the threaded shafts and matching nut-like components are relatively large, and it is often easy and convenient to screw in during assembly, and It can realize the automatic and continuous locking of the bearing capacity during use, so it is very reliable, but when it is disassembled, the assembly is often very tight, and disassembly is very difficult. It is particularly important to realize simple and easy disassembly under this condition
