Description

An intelligent monitoring device for pulp and foam full tank in flotation tank

technical field

The utility model belongs to the field of mineral processing engineering flotation, and in particular relates to an intelligent monitoring device for ore pulp and a froth full tank in a flotation tank.

Background technique

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 slurry in the flotation tank. Too much surface or too much foam will cause the overflow tank to escape. "Full tank" will not only lead to the loss of minerals, 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 during the concentrate flotation. When the "full tank" is found, emergency treatment or post-processing is made based on daily work experience; this traditional method consumes a lot of manpower, and The risk of "full tank" is high, which will inevitably lead to the loss of minerals and reduce the grade and recovery rate of concentrate products.

The three-dimensional model is compared with the standard model; if the foam height reaches the safety threshold and there is a tendency to fill the tank, the control system of the BIM server sends an activation program command to the alarm and the electric control valve electric actuator through the network switch; the alarm program is blocked. When activated, the indicator light of the alarm flashes to remind the staff, and the electric regulating valve is activated synchronously to adjust the output diameter of the slurry, reduce the level of the slurry, and avoid the overflow of "full tank" foam.
