Description

Technical Field

[0001] This utility model relates to the field of solid-liquid separation and sedimentation, and more specifically to a portable device capable of conducting multiple flocculation and sedimentation experiments simultaneously. Background Technology

[0002] In the mineral processing industry, ore undergoes crushing, grinding, and beneficiation processes to produce concentrate, while the remaining tailings are discharged into tailings ponds. Both tailings and concentrate require sedimentation and filtration in thickening tanks. During this sedimentation process, flocculants are often added to form flocs from fine solid particles, accelerating solid-liquid separation and improving the quality of the clarified supernatant. The compatibility between the flocculant and the slurry solution directly affects the flocculation and sedimentation effect; therefore, the selection of flocculants is a crucial technical aspect for mining companies. Selecting a flocculant necessitates experiments on the type and dosage of flocculants to identify economical and efficient options. Traditional flocculant experiments primarily use glass graduated cylinders for individual comparative tests, which suffers from low efficiency and lacks direct comparative analysis. Therefore, to address these shortcomings, a portable device capable of simultaneously conducting multiple flocculation and sedimentation experiments is urgently needed to improve experimental efficiency and accuracy.
