Separation equipment

Abstract

The invention discloses separation equipment which is used for separating solid matters with different settling velocities in a suspension. The separation equipment comprises a first separation device and a second separation device, wherein the first separation device is a fluidized separation device, and the second separation device is a belt-type separator. According to the separation equipment, the belt-type separator carries out secondary separation on a first solid matter which is separated from the fluidized separation device, contains a second solid matter and has lower settling speed, so that the second solid matter with lager settling speed in the first solid matter can be thoroughly separated, thus the separation effect is improved, and the first solid matter and the second solid matter can be thoroughly separated.

Description

technical field [0001] The invention relates to a separation device, in particular to a separation device for separating solid substances in a suspension having different settling velocities. Background technique [0002] Traditional separation equipment includes screens, cyclones, etc. Screening is mainly to classify the material through different mesh screens, and it can only be used to separate solid particles with larger particle sizes. The cyclone uses the principle of centrifugal sedimentation for solid-solid separation, but it cannot completely separate different solid substances from the suspension, and the separation effect is poor. For example, in the field of hydrometallurgy, it is usually necessary to purify the metals in the leaching solution by precipitation, and then separate solid particles with different particle sizes and weights, such as calcium sulfate and cobalt hydroxide or nickel hydroxide, etc., traditional separation equipment from the leaching solu...
