Intelligent monitoring device for ore pulp and foam fullness of flotation cell, and monitoring method thereof

Abstract

The invention discloses an intelligent monitoring device for ore pulp and foam fullness of a flotation cell, and a monitoring method thereof. The flotation cell is provided with a camera, an electromagnetic flowmeter, a collector, a network switch, a BIM server, an electric control valve and an alarm; the BIM server receives the data, transmitted by the network switch, of the collector, the electric control valve and the alarm, model building software in the BIM server generates a real-time three-dimensional model, and the control system automatically compares the real-time three-dimensional model with a standard model; and if the foam height reaches a safety valve value, the control system of the BIM server sends an activation program instruction to the alarm and the electric actuator ofthe electric control valve through the network switch, an alarm program is activated, and the electric control valve is synchronously started to regulate the ore pulp output caliber. The device and the method have the advantages of high automation degree, ensuring of smooth flotation production, reduction of the safety risk caused when a flotation device runs at a high speed and the tank is full,avoiding of mineral losses, and ensuring of the grade and the recovery rate of flotation concentrate products.

Description

technical field [0001] The invention belongs to the field of mineral processing engineering flotation, and in particular relates to an intelligent monitoring device and a monitoring method for a flotation tank full of slurry and foam. Background technique [0002] Metals such as lead, zinc, sulfur and other concentrates can only be obtained through flotation. There are many types of minerals and the flotation process is complicated. The phenomenon of "full tank" often occurs in the actual flotation production of the concentrator, that is, the ore slurry in the flotation tank If the surface is too high or the amount of foam is too much, it will escape the overflow tank. "Full tank" will not only lead to mineral loss, but more importantly, it will affect the grade and recovery rate of concentrate products, and also directly lead to economic losses of the concentrator. At present, the traditional method is to arrange experienced operators to be on duty 24 hours a day when the c...

[0002] Metals such as lead, zinc, sulfur and other concentrates can only be obtained through flotation. There are many types of minerals and the flotation process is complicated. The phenomenon of "full tank" often occurs in the actual flotation production of the concentrator, that is, the ore slurry in the flotation tank If the surface is too high or the amount of foam is too much, it will escape the overflow tank. "Full tank" will not only lead to the loss of minerals, but more importantly, it will affect the grade and recovery rate of the concentrate product, and also directly lead to the economic loss of the concentrator.

At present, the traditional method is to arrange experienced operators to be on duty 24 hours a day when the concentrate flotation is in progress. When a "full tank" is found, emergency treatment or post-processing is done based on daily work experience; this traditional method consumes a lot of manpower. The risk of "full tank" is high, which will inevitably cause the loss of minerals and reduce the grade and recovery rate of concentrate products
