System for automatically controlling thickening parameters in photoelectric monitoring thickening process and corresponding thickener

Abstract

According to the system for automatically controlling the thickening parameters in the photoelectric monitoring thickening process and the corresponding thickener, the innovative scheme has the key points that 1, on the basis of vacuum perspective container equipment of the existing thickener, a T18-6MX type photoelectric detection instrument is additionally arranged, and an existing concentration detection device is cancelled; the photoelectric detection instrument can monitor the thickening process (including settling velocity and time) on line in real time and transmit detection data to the PLC control system; 2, a PLC control system is adopted to replace an existing non-intelligent electrical control system, the PLC control system dynamically compares detection data with design parameters in real time and intelligently controls thickening parameters, the feeding amount and the reasonable dosage of a flocculating agent are adjusted in time, waste of the flocculating agent is avoided, and the material concentration effect is guaranteed. The thickener is an automatic thickener, and a system for monitoring the thickening process through photoelectricity and automatically controlling thickening parameters is used; the technical problems that a concentration detection instrument loses efficacy or a detection result is distorted, and thickening parameters (including the feeding amount, the dosage and the concentration effect) cannot be intelligently controlled are solved.

Description

technical field [0001] The invention belongs to the technical field of automatic thickeners, and relates to a system for monitoring thickening process (including settling speed and time) and automatically controlling thickening parameters (including feeding amount, dosing amount and concentration effect). Background technique [0002] Thickener (also called thickener) is a solid-liquid separation equipment based on gravity sedimentation; automatic thickener is a thickener that automatically controls thickening parameters (including feed amount and dosing amount) by detecting material concentration. It consists of a concentration tank, a thickening mechanism, a concentration detection device, and an electrical control cabinet; the concentration tank includes a cone-bottom cylinder, a discharge port, and an overflow port; the thickening mechanism includes a drive motor, a reducer, a scraper shaft (rake rod), Scraping rake; concentration detection device, which can only detect ...
