Description

Technical Field

[0001] The utility model relates to the field of ore dressing equipment, in particular to a double-shaft stirring tank for ore dressing which is convenient for maintenance. Background Art

[0002] The stirring tank is one of the important auxiliary equipment in the flotation process and plays an important role in the mixing operation of pulp and medicament. The pulp conditioning stirring tank mainly realizes the mixing and uniform mixing operation of materials and medicament in a mechanical stirring manner, so as to ensure the stirring and contact time between the medicament and the mineral, and realize the full dispersion of the mineral and the complete reaction of the medicament. Ores often need to be finely ground before flotation and can only enter the flotation equipment after being ground to a certain particle size to improve the flotation index.

[0003] In the ore dressing industry, the stirring tank is mainly used for the pulp stirring before the flotation operation to mix the medicament and the pulp. At present, some stirring tanks have a simple structure. When pouring in the pulp and ore dressing medicament, due to the large density and weight of the pulp, the stirring blades of the mixer are difficult to fully stir the pulp, so sufficient stirring cannot be carried out, which affects the full mixing reaction of the pulp and the ore dressing medicament and results in poor ore dressing quality. A lot of impurities will be generated during the mining and transportation of minerals. If the other impurity components contained in the pulp cannot be removed in time before entering the flotation equipment, it will affect the internal liquid environment during flotation and the flotation effect. Moreover, at present, most of the stirring tanks adopt a fixed upper cover structure and cannot be easily opened. When removing the tailings in the barrel or performing maintenance activities such as replacing the blades, disassembly operations are required, which are very time-consuming and laborious.
