The frequency control deep cone concentrator centre independent stirring device comprises a driving device, a connecting supporting device, a machine base, a mixer shaft, a coupling flange disc, a deflection preventing device, an upper spiral scraper, a lower part positioning device, a lower spiral scraper and a lower mixing blade, wherein the driving device is arranged on the machine base through the connecting supporting device and comprises a frequency control device and an output power device, and the output end of the output power device is connected with the mixer shaft through a coupler; and the mixer shaft finishes self connection through the connecting flange disc, the deflection preventing device is arranged on the lower part of the mixer shaft, and the upper spiral scraper, the lower part positioning device, the lower spiral scraper and the lower mixing blade are successively arranged on the bottom of the mixer shaft. The frequency control deep cone concentrator centre independent stirring device provided by the invention adopts an independent rabbling mechanism so as to be free from the influence of the rotate speed of a rake frame, the rotate speed is adjusted according to different material properties and underflow concentration, a rotation speed signal is transmitted to a central control room, the use is very convenient, and the frequency control deep cone concentrator centre independent stirring device is safe and reliable, is durable in use and is strong in practicability.

Description

technical field [0001] The invention relates to an independent stirring device for the center of a deep cone thickener with frequency conversion and speed regulation, which is mainly used for central stirring of the deep cone thickener. Background technique [0002] Due to the high underflow concentration of the deep cone thickener, small footprint, large processing capacity, and high efficiency, the deep cone thickener has become more and more popular in coal preparation, mineral processing, sewage treatment and other industries in recent years, especially with large-scale With the birth of center drive and center rake deep cone thickeners in China, the promotion and popularization of deep cone thickeners is getting faster and faster. However, due to the deep center depth of the deep cone thickener, the material concentration in the deep cone cone pit is high, basically paste, high viscosity, high shear strength, difficult to discharge, easy to harden, especially for large ...

AI Technical Summary

Problems solved by technology

However, due to the deep center depth of the deep cone thickener, the material concentration in the deep cone cone pit is high, basically paste, high viscosity, high shear strength, difficult to discharge, easy to harden, especially for large thickeners, with the thickener As the diameter increases, the central depth of the concentrator will be deeper, and the phenomenon of clogging of the cone pit, material compaction, and inability to discharge will become more serious, especially for tailings concentration of laterite nickel ore.

[0003] Now, the difficulty of underflow discharge of large deep cone thickeners has become a worldwide problem, and it has become a bottleneck restricting the development of large deep cone thickeners, and whether the problem of underflow discharge of large deep cone thickeners can be solved is the key to breaking through this bottleneck , both at home and abroad have done many years of research on this technology, but still can't find a good solution
