Control device based on PLC computer system

Abstract

The invention discloses a control device based on a PLC computer system, which comprises a furnace body, the top of the furnace body is fixedly connected with a connecting table, a powder material pipe and a block material pipe are arranged at the top of the connecting table in a penetrating mode, and a partition plate is rotationally connected in the powder material pipe and the block material pipe; the inner top wall of the furnace body is fixedly connected with a discharging mechanism for controlling the discharging method of powder and lump materials; and the inner wall of the furnace body is fixedly connected with a bottom plate, and the top of the bottom plate is provided with a vibration mechanism for preventing coal ash accumulation. According to the control device based on the PLC computer system, coal fuels in two different states are fed according to work, when the temperature is insufficient, whether coal lacks or not is determined firstly, if coal lacks, a partition plate in a lump material pipe is turned over, a channel is opened, and lump materials fall into a furnace body, and after the lump materials are fed, a partition plate in a powder material pipe is turned over, the channel is opened, the powder is carried by the air flow generated by a fan to be sprayed into the furnace body to support the combustion of the block materials, and the temperature in the furnace can be quickly increased, so that the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of PLC control, in particular to a control device based on a PLC computer system. Background technique [0002] The full name of PLC is programmable logic controller, which is an electronic device specially designed for industrial production. It uses a type of programmable memory for its internal storage program, logic operation, sequence control, timing , Counting and arithmetic operations and other user-oriented instructions, and control various types of machinery or production processes through digital or analog input / output, are the core parts of industrial control. [0003] Industrial boilers are equipment used to provide power, heat, and hot water in industrial production. Due to the simple feeding method of boilers at present, the combustion efficiency of boilers is low, the temperature adjustment is slow, and the energy utilization rate is low. Therefore, we propose a PLC-based computer system contr...
