Problems solved by technology
At present, the main method of flotation dosing is to insert the reagent pipeline directly into the middle box of the flotation machine or the flotation tank. The reaction time between the reagent and the pulp is short, the dispersion effect is poor, and the flotation index is affected. On the machine selection platform, it brings inconvenience to production operation and equipment maintenance

The invention belongs to the technical field of mineral separation, and particularly relates to a bottom agent-adding device for a flotation machine. The bottom agent-adding device is characterized by comprising a group of agent inlet pipes arranged at the bottom of a slot body of the floatation machine and extending into an impeller cavity, a group of vacuum generators of which the outlets are connected with the group of agent-adding pipes, an air compressor connected with the inlets of the group of vacuum generators by a compressed air pipeline, an agent box arranged at one side of the group of vacuum generators and connected with the group of vacuum generators by a group of agent-adding pipes, a group of check valves arranged on the group of agent inlet pipes respectively, and solenoid valves arranged on the agent-adding pipes. The bottom agent-adding for the floatation machine is realized, agents are directly input into the impeller cavity and can be fully mixed with ore pulp, and meanwhile the formed air agent suspension system can fully disperse the flotation agents, thus improving the agent acting effect, accelerating floatation speed, reducing the agent consumption and achieving the effect of improving the floatation index.
Description
technical field [0001] The invention belongs to the technical field of mineral separation, and in particular relates to a dosing device at the bottom of a flotation machine. Background technique [0002] Flotation is a technical method for separating useful minerals from ores according to the different physical and chemical properties of the surface of mineral particles. It is widely used in the separation of fine-grained and ultra-fine-grained materials. A flotation machine is a mechanical device that completes the flotation process. In the flotation machine, the ore pulp that reacts with the chemical is stirred and inflated, so that some of the ore particles are selectively fixed on the air bubbles, float to the surface of the ore pulp and are scraped off to form a foam product, and the rest remain in the ore pulp. , in order to achieve the purpose of separating minerals. One or more chemicals need to be added in the flotation production process, and the types of chemica...
