Technical Field

The utility model relates to a buffer memory storehouse with discharging device 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.
