Abstract

The invention relates to an on-line magnetic iron detection and alarm device and method for magnetite tailings. The on-line magnetic iron detection alarm device comprises a tailing groove, a mine cutting pipe, a pulp groove, a magnetic separation device for pulp and a detection and early warning device, wherein the magnetic separation device for pulp is composed of a driving device, a driving shaft, a permanent magnetic separation disc, two mine discharging grooves and two water filling devices; the mine discharging grooves are fixed on the pulp groove through a support; the detection and early warning device is composed of a fixed frame, two thickness detection sensors, an analog and digital converter, a computer and a photoelectric alarm; and the two thickness detection sensors are respectively arranged on one outer sides of the two end faces of the permanent magnetic separation disc. The on-line magnetic iron detection and alarm device and method provided by the invention can timely detect the change of magnetic iron in the tailings and make preliminary judgment on an operation state of the magnetic separator, thus avoiding the situation that the content of the magnetic iron in the tailings is out of limits for a long time; and meanwhile, the on-line magnetic iron detection and alarm device and method can make preliminary judgment on a part out of limits and narrow an investigation range, so that the parts out of limits can be disposed in real time, and the labour intensity of operating staffs is relieved.

Description

technical field [0001] The invention belongs to the technical field of iron ore separation, and relates to an online detection and alarm device for magnetic iron in magnetite tailings and a detection and alarm method. Background technique [0002] In the existing field of magnetite beneficiation technology, whether a single magnetic separation process or a magnetic-flotation joint separation process is adopted, magnetic iron (iron in strong magnetic minerals) inevitably exists in the tailings. Therefore, Almost all large-scale concentrators in China use weak magnetic recovery machines to recover the magnetic iron in the tailings, and use the re-election process to re-select the recovered magnetic iron to increase the output of concentrates, reduce the grade of tailings, and increase the metal recovery rate. the goal of. [0003] The content of magnetic iron ore in tailings is affected by many factors, such as sorting equipment failure, untimely operation and adjustment of o...
