Rotary river sand iron separation device

Abstract

The invention discloses a rotary river sand iron separation device, which comprises a base, a screening box and a screening barrel; a frame is fixedly installed on the left side of the base, and a top plate is fixedly installed on the upper side of the frame; the screening box passes through The installation frame is fixedly installed on the inner side of the frame; an exhaust fan is fixedly installed on the upper side of the top plate, an air inlet is arranged on the right side of the exhaust fan, and a disc-shaped air outlet is arranged on the top of the screening box; the screening The inside of the box is symmetrically installed with a first turning roller and a second turning roller; the inside of the screening box is fixedly installed with a fixed sieve plate on the lower side of the first turning roller, and the lower side of the fixed sieve plate is also provided with a movable Sieve plate; the sieve bucket is rotatably installed at the bottom of the sieve box. The invention adopts the method of pumping and air-drying to dry the river sand, avoiding the magnet degaussing caused by high temperature, and improving the efficiency of iron selection; the iron powder is screened out from the dried river sand by setting a rotating rotary barrel, and the screening effect is excellent.

Description

technical field [0001] The invention relates to an iron selection device, in particular to a rotary river sand iron selection device. Background technique [0002] River sand is a non-metallic ore with complex components, smooth surface and high impurity content, which is produced by natural stones in the natural state, repeatedly collided and rubbed by the force of water for a long time. The grains of river sand are smooth, relatively clean, and come from a wide range of sources; river sand has no taste, while sea sand has a salty taste. [0003] Most of the river sand contains a certain amount of iron powder, which is widely used in industry, so the river sand iron separation process emerged as the times require; the existing river sand iron separation devices generally use magnetic separation to select iron. Sand contains a certain amount of water, wet river sand is not conducive to iron selection, and drying the river sand by heating will bring a certain temperature to ...

Problems solved by technology

[0003] Most of the river sand contains a certain amount of iron powder, which is widely used in industry, so the river sand iron separation process emerged as the times require; the existing river sand iron separation devices generally use magnetic separation to select iron. The sand contains a certain amount of water. Wet river sand is not conducive to iron selection, and drying the river sand by heating will bring a certain temperature to the river sand, which will affect the magnet and reduce the iron selection effect.
