Control system and method for dry method sorting device

Abstract

Disclosed are a control system and a method for a dry method sorting device. The control system comprises a material feeding medium sensor, a material discharging coal dust medium sensor, a material discharging coal gangue medium sensor, a control main machine, a vortex motor frequency changing and speed setting controller, an air door adjusting driving machine and a spiral material conveying controller. When materials are sorted, signals are collected in real time through the material feeding medium sensor, and the detected signals are sent to the control main machine, so that quantity containing gangue components in the coal sorting materials is confirmed, and the speed of the vortex motor frequency changing and speed setting controller is controlled so as to carry out rough sorting. The materials after rough sorting enter an air sorting device, detection information is obtained through the material discharging coal gangue medium sensor, an air door valve and a spiral material conveying device are automatically controlled, so that fine sorting is achieved. The defect of poor mechanical adaptability of a traditional coal sorting machine is overcome, the turbine revolving speed can be adjusted automatically according to coal quality of different fed materials, and the air door of spiral material conveying and air sorting can be automatically adjusted according to the detection of coal dust and gangue dust at a material outlet at the same time, so that the best coal sorting effect can be achieved.

Description

technical field [0001] The invention relates to a control system and method of a dry separation device, and is especially suitable for the control of a coal separation device in coal industrial production. Background technique [0002] Coal preparation is an essential link in the coal industry to improve product quality, an effective way to comprehensively utilize resources, save energy and protect the environment, and is also an important part of clean coal technology in my country's century sustainable development strategy. At present, the energy development strategy is shifting from energy development to energy economic efficiency, with equal emphasis on energy development and conservation, with priority given to conservation, economic and social benefits in development, and the core of which is to increase energy utilization. Coal preparation is the most economical and effective way to rationally utilize coal resources and protect the environment, and is an indispensable...
