Description

Technical Field

[0001] The invention belongs to the technical field of mineral processing flotation reagent distribution, and in particular relates to a flotation powder reagent preparation mechanism and a use method. Background Art

[0002] At present, in the flotation process, powdered reagents are generally prepared on-site in a mixing tank, and the structure of the mixing tank is mainly composed of a stirrer, water inlet, valve, cover, pulley, buoy weight counterweight level gauge, weight, scale, reagent pump and tank body, etc. When preparing the reagent, it is usually done by manually adding the reagent and controlling the amount of water added, and operating the stirrer to stir the solution. After completion, the solution is transported to the reagent box of the flotation dosing platform through the reagent pump at the bottom of the mixing barrel, and added to the flotation tanks of each flotation zone.

[0003] Since some powdered medicines need to be filled with hot water to generate steam during the preparation process, it is not suitable to set an electronic level gauge in the tank, and the liquid level cannot be observed manually. Instead, a float weight counterweight level gauge is used, with a scale set on the outside of the tank, and the liquid level is estimated by observing the position of the weight. The following problems often occur: 1. Since each person has a different height, the angle of the scale outside the mixing barrel is different, and the liquid level is observed differently. The medicine and water are added based on experience, resulting in unstable preparation concentration, which leads to fluctuations in flotation quality; 2. The medicine and water need to be added manually, which is laborious and time-consuming; 3. During the use of the medicine, since there is no liquid level alarm, the liquid level of the medicine tank needs to be checked frequently, which not only increases the labor intensity of employees, but also often fails to find out the exhaustion of the medicine in time, resulting in medicine shortage accidents, affecting the flotation index. Therefore, solving the accuracy of flotation preparation and preventing medicine shortage accidents are of great significance to flotation production. Summary of the invention
