Abstract

The invention relates to a flotation machine liquid level automatic control device and method and belongs to the flotation machine technical field. The device comprises a flotation machine liquid level automatic detection system, a flotation machine liquid level automatic adjustment system and a control box; the flotation machine liquid level automatic detection system comprises a liquid level gauge, a first guide rod and a guide rod fixing plate; the flotation machine liquid level automatic adjustment system is wholly vertical to the liquid level of a flotation machine; the flotation machine liquid level automatic adjustment system comprises a circular truncated cone-shaped dart valve, a second guide rod and an electric hydraulic push rod; the electric hydraulic push rod comprises a telescopic push rod, a hydraulic cylinder, a reversible motor and an electric hydraulic dynamic push rod supporting beam; and the signal output end of the liquid level gauge and the signal input end of the reversible motor are both connected with the control box. The flotation machine liquid level automatic control device of the invention has the advantages of high automation degree and timely and accurate liquid level adjustment. With the flotation machine liquid level automatic control device adopted, automatic detection and automatic adjustment flotation liquid level can be realized, and the optimal liquid level of flotation operation can be ensured, and advantageous safeguard can be provided for the acquisition of qualified flotation indexes.

Description

technical field [0001] The invention belongs to the technical field of flotation machines, in particular to an automatic liquid level control device and method for a flotation machine. Background technique [0002] The flotation equipment used in the flotation operation of the mineral processing plant is mainly a flotation machine and a flotation column. Since the microbubble generator of the flotation column relies on the Venturi action during the self-circulation of the captured pulp to generate microbubbles, the ore particles are Venturi fine mouth wears a lot, so the application of flotation columns in mines is limited to a certain extent. Currently, flotation machines are the most widely used in mines. Below the overflow of the flotation machine, it is divided into a pulp layer and a foam layer. The interface between the pulp layer and the foam layer is the flotation liquid level. The height of the flotation liquid level directly determines the height of the flotation f...
