Abstract

The invention discloses an efficient classification and thickening machine for tailing slurry. The efficient classification and thickening machine comprises a supporting frame, a hopper, a material classifying device, a stirring device, a backflow pipe, an overflow tank and an unloading device. The hopper, the material classifying device, the stirring device, the backflow pipe, the overflow tank and the unloading device are arranged on the supporting frame. The hopper is internally divided into a classifying cavity and a material storing cavity through a partition plate. The material classifying device is arranged in the classifying cavity. The material classifying device comprises a primary material chamber, a secondary material chamber, a fall pressure chamber and a circulation plate. The stirring device comprises a first rotating shaft, a second rotating shaft and a slurry pump. The first rotating shaft and the second rotating shaft are hollow and are each in a cylindrical shape. One end of the first rotating shaft is connected with a motor in a transmission mode, and the other end of the first rotating shaft extends into the material storing cavity sequentially through the fall pressure chamber, the secondary material chamber and the primary material chamber. The first rotating shaft is sleeved with the second rotating shaft. The top end of the backflow pipe is arranged above the circulation plate and is lower than the top of the fall pressure chamber. The unloading device is arranged at the bottom of the material storing cavity and comprises a feed cylinder, a material guide cylinder, a spiral bevel gear and a transmission shaft.

Description

technical field

[0001] The invention relates to a tailings treatment device, in particular to a tailings slurry high-efficiency classification thickener. Background technique

[0002] Using thickening equipment to increase the concentration of tailings is a commonly used method at present. At present, thickeners are mainly divided into traditional thickeners, high-efficiency thickeners and high-efficiency deep cone thickeners.

[0003] The traditional thickener consists of a shell, a driving device and a rake scraper. The solid particles suspended in the slurry in the thickening tank settle under the action of natural gravity, and the upper part becomes clarified water to separate the solid and liquid. The slime deposited at the bottom of the thickening tank is continuously scraped and collected by the rake scraper to the discharge port at the center of the bottom of the tank, while the clarified water overflows from the upper edge of the thickening tank.
