Intelligent horizontal screw machine operation control system and method

Abstract

The invention relates to an intelligent horizontal screw machine operation control system comprising a PLC control box, a main motor, an auxiliary motor, a stirring tank motor, a screw conveyor motor,an electric knife gate valve, a feeding pump and an electric three-way valve. The main motor is connected to a drum of the horizontal screw machine, the auxiliary motor is spirally connected to the horizontal screw machine through a differential mechanism, the stirring tank motor is connected with a stirring shaft arranged in a stirring tank, the screw conveyor motor is connected with a screw shaft in a screw conveyor, the electric knife gate valve is arranged on a slag outlet pipe between a drum small end slag outlet of the horizontal screw machine and a feeding opening of the screw conveyor, and the feeding pump and the electric three-way valve are arranged on a feeding pipe between a discharging opening of the stirring tank and a feeding opening of the horizontal screw machine. A highly-integrated and intelligent control system is adopted, so that the whole operation state of the horizontal screw machine is effectively monitored, automatic running is carried out in all startup, running and shutdown processes of the horizontal screw machine according to an electronic control program, the labor intensity is greatly reduced, and the operation reliability of the horizontal screw machine is improved.

Description

technical field [0001] The invention relates to an intelligent horizontal screw machine operation control system and method, belonging to the technical field of mechanical equipment automatic control. Background technique [0002] It is understood that the decanter is a general-purpose equipment for solid-liquid separation using the centrifugal force generated by high-speed rotation. After the separated material enters the drum, due to the density difference between the solid and liquid, under the action of centrifugal force, the solid It settles quickly to the inner wall of the drum, and the liquid phase settles to the surface of the solid phase. The drum and the screw rotate in the same direction, and there is a speed difference between the drum and the screw. The solid phase is pushed to the slag outlet at the small end of the drum under the action of the screw, and the liquid phase passes through the slag outlet on the shaft of the large end cover. The liquid outlet is ...

AI Technical Summary

Problems solved by technology

[0003] The existing control system of the decanter machine is generally intelligent and the degree of automation is not high. In the actual production process, it must be manually on duty, and the labor intensity is relatively high. The control system cannot detect various index parameters during the operation of the decanter machine. The failures that may occur during the operation of the horizontal screw machine cannot be effectively predicted and diagnosed, resulting in the prone to failure of the horizontal screw machine, which needs to be disassembled for inspection, which greatly affects normal production
