a desilting tank

Abstract

The invention discloses a desliming tank, comprising: a tank body (1), a slurry valve is provided on a discharge pipe (9) at the bottom of the tank; a material receiving cylinder (2) is provided with a feeding pipe (2- 1); the central axis (3) is arranged along the axial centerline of the tank body (1), and the tank body (1) is provided with a driving device for driving its rotation; the distribution plate (4) is installed on the The central shaft (3) is located below the discharge port at the bottom of the receiving cylinder (2); the flushing water tray (5) is installed on the central shaft (3) and located in the middle of the tank (1) The lower area is provided with a water spray port; the water supply device (6) communicates with the water spray port of the flushing water tray (5) through the channel inside the central shaft (3); the overflow tank (7), An overflow pipe (7‑1) is provided on it. The desliming tank has high desliming and concentration efficiency, large production capacity per unit area, and a single unit can achieve the effect of two-stage or even multi-stage desliming and concentration.

Description

technical field [0001] The invention relates to the technical field of mineral processing equipment, in particular to a desliming tank used for desliming treatment of ore pulp. Background technique [0002] Desliming and thickening are common operations in the beneficiation production process. The basic principle is to use the ore (or ore aggregate) to settle out of the slurry by its own gravity to achieve the purpose of desliming or dehydration. [0003] At present, conventional desliming and thickening equipment mainly include desliming buckets, thickeners, inclined plate thickeners, etc. [0004] The desliming hopper is also widely used in small and medium-sized mineral processing plants in my country. It is mainly used to deslim and concentrate the feed material before sorting and grading operations, and it also plays a buffer role. However, due to its low concentration and desliming efficiency and small equipment specifications, it is gradually being replaced by thicke...

AI Technical Summary

Problems solved by technology

Its disadvantage is that when the pulp moves in the equipment, the disturbance is small, which is not conducive to the dispersion of particles in the pulp, especially when it is used in the selective flocculation and desliming process of selectively adsorbing and flocculating useful mineral particles to remove gangue slime. Useful minerals will entrain a large amount of gangue mud that should have been discharged from the overflow and sink, resulting in poor desliming effect
