TECHNICAL FIELD
[0001] The utility model belongs to the technical field of floatation machine, especially a kind of general floatation machine connecting tank. BACKGROUND
[0002] Floatation machine is a kind of equipment widely used in the field of mineral processing, mainly used for separating useful minerals from gangue minerals in ore. Its working principle is based on the difference of physical and chemical properties of mineral surface, and the separation of minerals is realized through a series of complex physical and chemical processes. Generally, the raw ore needs to be crushed and ground into fine particle size slurry, and the slurry is transported into the floatation machine, and specific flotation reagent is added, then the aeration device at the bottom of the floatation machine starts to work, and air is filled into the slurry to form bubble rising flow. Because the surface of target mineral particles has hydrophobicity after being affected by collector, they will adhere to the rising bubbles and rise to the surface of slurry with the bubbles to form foam layer. While gangue mineral particles remain hydrophilic due to ineffective action of collector, they remain in the slurry. Finally, the foam layer on the surface of the floatation machine is scraped out by mechanical bubble scraping device, and the foam layer is rich in target useful minerals. These foams can be further processed to obtain high-grade concentrate products, while the remaining slurry part is discharged as tailings, thus completing the separation process of useful minerals and gangue minerals. However, the existing floatation machine connecting tank has the problems of complex structure, large space occupation, slow discharge rate and high energy consumption, which is not conducive to reducing the construction and production cost of floatation machine.

[0025] For example, the slurry feeding mechanism 2 and the tailings discharge mechanism 3 can adopt the structure used on the existing flotation machine, such as slurry feeding pipe and slurry discharge pipe, which can be fixed on the tank body 1 and communicated with the tank body 1.
