Description
Technical Field
The utility model relates to a material feeding unit of establishing ties for the coal processing field.
Background
China is a country with more coal, less oil and poor gas, and in the petrochemical energy reserves proven in China, oil and natural gas only account for 6 percent, and the rest 94 percent are coal substances. The resource characteristics determine that China mainly builds energy structures by using coal substances.
The DCS System is an english abbreviation (Distributed Control System) of a Distributed Control System, and is also called a Distributed Control System in the domestic automatic Control industry. The computer control system is a novel computer control system relative to a centralized control system, and is developed and evolved on the basis of the centralized control system.
A PLC system, also known as a programmable logic controller, is a digital arithmetic operation electronic system designed specifically for use in an industrial environment. It uses a programmable memory, in which the instructions for implementing logical operation, sequence control, timing, counting and arithmetic operation are stored, and utilizes digital or analog input and output to control various mechanical equipments or production processes.
In the field of coal processing, a large-scale coal processing system is basically controlled by adopting a DCS (distributed control system), distributed management is facilitated, centralized control can be realized, and a common PLC (programmable logic controller) system for a medium-small coal processing system is only required to be controlled in one place in a centralized manner.

The existing feeding devices are often connected in parallel or in series due to actual needs, and particularly on the feeding devices connected in series, due to the superposition of safety defects, more safety defects exist, and more potential safety hazards exist.
