Control method for super extra gravity settling separator

Abstract

The invention discloses a control method for a super extra gravity settling separator, and belongs to the technical field of separating process and equipment control. The invention mainly solves the problems that production efficiency is low, labor intensity is high and the like due to a natural settling method in the conventional infusorial earth separation. The control method is characterized by comprising ore pulp concentration control, feed flow control, separation control and a control instrument, wherein the ore pulp concentration control comprises a suspended matter concentration meter and a water supply solenoid valve; the feed flow control comprises an ultrasonic flowmeter and a hydraulic valve; the separation control comprises a feed pump, a feed solenoid valve, a return flow solenoid valve, a water flushing solenoid valve, a concentrate solenoid valve, a tailing solenoid valve, a slip motor and an electromagnetic speed setting controller; and the control instrument is connected with the ore pulp concentration control, the feed flow control and the separation control. By the control method, original infusorial earth is separated in a strengthened mode in a centrifugal force field under the optimal conditions, automatic, efficient, continuous and stable production is realized, and the control method is particularly suitable for separating clay materials.

Description

technical field [0001] The invention relates to the technical field of mineral processing technology and equipment control, in particular to a control method of a supergravity sedimentation separator. Background technique [0002] Diatomaceous earth is a natural nano-microporous and regular distribution, large specific surface area, small bulk density, the main component is amorphous SiO 2 The natural siliceous porous non-metallic minerals are widely used in the filtration of beer, beverages, drinking water, industrial oils, etc., as well as in the fields of sewage treatment, building materials, chemicals, agriculture, rubber and plastic fillers, paper fillers, etc., and are indispensable for many industries. Mineral functional mineral materials have broad application prospects. [0003] my country is a country with large reserves of diatomite, second only to the United States in the world, ranking second. However, most of the diatomite reserves in my country are low-grade...

Problems solved by technology

However, it takes a long time for the slurry to settle and stratify in the gravity field, which leads to problems such as low production efficiency, high labor intensity, and non-continuous production.
