Thickener control system

Abstract

The invention provides a thickener control system. An acquisition system of a field control cabinet sends electrical signals of operating state of the thickener through a control system, a storage system and an executive system so that a rotary bridge, a scrapping and collecting device and a hydraulic system of the thickener can automatically run according to programs; the field control cabinet is connected to a power source by a current collector; the electrical signals of operating state of the thickener are transmitted to a remote console by wireless communication, the remote console controls the field control cabinet by the wireless communication to control operation of the thickener so as to complete the rotary bridge control, the scrapping and collecting device control, the hydraulic system control, fault alarm and interlock control; and remote control, automatic control and manual control are provided. The system can automatically lift rakes one by one, realize mechanical pool cleaning function, avoid water discharge for cleaning, reduce waste, and greatly increase economic benefit of users. The remote operation realizes wireless communication between the rotary PLC controlcabinet and a ground touch screen by Ethernet.

Description

Concentrator control system technical field The invention belongs to the technical field of electric automatic control, and is especially suitable for a concentrator control system for concentrating and purifying suspensions in coal, chemical, building materials and sewage treatment industries. Background technique Thickeners are widely used in coal, chemical, building materials and sewage treatment industries to concentrate and purify suspensions. Especially in today's shortage of energy and resources, the demand for concentrators in industries such as sewage treatment and concentrate extraction will increase. The solid particles in the suspension in the concentration tank settle under the action of gravity, so that the solid and liquid can be separated, and the upper part is clarified water. The sediment deposited at the bottom of the concentration tank is continuously scraped and collected by the scraping device to the ore discharge port at the center of the bottom of...
