PLC-based automatic batch ingredient pneumatic conveying system

Abstract

The invention discloses a PLC (Programmable Logic Controller)-based automatic batch ingredient pneumatic conveying system. The system is characterized by comprising a blower, pressure gauges, safety valves, material level sensors, gate valves, hoses, a delivery pump, butterfly valves, a control system panel, stop valves, dust collectors, target bunkers, air tanks, shunt valves and storage silos, wherein the air tanks are connected with the pressure gages and the dust collectors; the dust collectors are connected with the storage silos; the material level sensors are arranged on the storage silos; the bottoms of the storage silos are connected with the gate valves; the gate valves are connected with the hoses; the hoses are connected with the delivery pump; the delivery pump is connected with the blower; the shunt valves are connected to the dust collectors; the bottoms of the dust collectors are connected to the target bunkers; the safety valves are arranged on the target bunkers; the bottoms of the target bunkers are connected with the butterfly valves and the stop valves; and the control system panel is connected with the blower. According to the invention, the automatic control of the automatic powder batch ingredient pneumatic conveying manufacturing process can be realized, and the work efficiency is improved.

Description

technical field [0001] The invention relates to a conveying system, in particular to a PLC (Programmable Logic Controller, Programmable Logic Controller)-based automatic batch batching pneumatic conveying system. Background technique [0002] Generally, industrial production process can be divided into continuous production process, batch production process (intermittent production process) and discrete production process according to whether the output product is a continuous product flow, discrete batch or discrete quantity. A mass production process is a process in which mass production of products is carried out in a sequence of operating steps. [0003] In foreign countries, the DCS control system (that is, the process control system) produced for the continuous production process has greatly advanced the automation of the production process. Whether the DCS control system is configured is almost a sign of judging the level of automation. With the intensification of c...
