Detailed Description

The principles and features of the present invention will be described with reference to the drawings, which are provided for illustration only and are not intended to limit the scope of the invention.

Example 1

In the processing process of certain silicate non-metallic minerals, dilute sulfuric acid is added to leach iron impurities in the minerals to generate high-valence iron ion leaching slurry containing non-metallic solid minerals, and under the condition of not filtering the leaching slurry, active metal powder is added into the slurry, and a system generates a displacement reaction to form displacement liquid containing simple substance iron powder. Adopt the utility model (concentrate pickling thick liquid → reduction replacement iron → physics magnetism is inhaled deironing → contains the iron slag) integration deironing device gets rid of the simple substance iron powder in the replacement liquid.

In operation, as shown in FIGS. 1-3, the inlet valve F1 and outlet valve F2 are opened, and the residue discharge valve F3 and inlet valve F4 are closed.

Replacement liquid in the reaction kettle 6 enters the iron remover 4 through a circulating pump 5 and a feeding pipe L1, enters the iron removing area through a feeding hole 42 in a buffer area, and is blocked by a buffer strip 45 to control the magnetic attraction effect; when the liquid level exceeds the buffer strip, the liquid flows into the next iron removal block, and simultaneously the magnet 3 below the bottom plate of the iron remover 4 performs magnetic attraction to adsorb iron powder in the replacement liquid on the bottom plate of the iron removal block; the replacement liquid sequentially flows through the last iron removing block, flows into a collecting region from a discharge hole 44 and returns to the reaction kettle 6 through a discharge pipe L2; the simple substance iron in the replacement liquid is removed by continuous and cyclic adsorption, and one operation period is 30-60 minutes. One wash is performed after one or more cycles of operation.

During cleaning, the feeding valve F1 and the discharging valve F2 are closed, and the deslagging valve F3 and the water inlet valve F4 are opened. The inclination angle of the base box 2 is increased, and the water flow speed is increased. The inclination angle of the base box 2 is adjusted to 20 degrees by adjusting the jackscrew. Tap water enters the iron remover 4 through the water inlet pipe L4 to wash the iron slag deposited on the bottom plate, and flows into the iron slag collecting barrel 7 through the slag discharge pipe L3.
