Embodiment Construction

[0020] like figure 1 , 2 As shown: the concentrator control system mainly controls the operation status of the concentrator equipment through the programmable logic controller PLC; completes the monitoring and remote control of the equipment through the touch screen, and truly reflects the operation status of the equipment; that is The electric signal of the operation status of the concentrator is transmitted to the remote operation console through wireless communication, and the remote operation console controls the operation of the concentrator through wireless communication to control the on-site control cabinet to complete the control of the rotating bridge, the control of the scraping device, the control of the hydraulic system, the fault alarm and Chain control. The system includes: on-site control cabinet, power supply, wireless communication and remote operation console. The acquisition system of the on-site control cabinet transmits the electrical signal of the opera...

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 control cabinet and a ground touch screen by Ethernet.

Description

technical field [0001] 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 [0002] 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. [0003] 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 the t...
