Self-cleaning iron ion removing separation device

Abstract

The invention relates to a separation device, in particular to a self-cleaning iron ion removing separation device. According to the technical proposal provided by the invention, the bottom of a bucket body is a filter bed for placing the mixture of manganese sand and B metal, the filter bed is internally provided with a water distribution cover, and the upper part of the bucket body is provided with a water supply pipe which is connected with the water distribution cover; the bucket body is internally provided with an outlet sand pipe, the lower end of the outlet sand pipe is located at the bottom of the bucket body, and the upper end of the outlet sand pipe is connected with a twisted dragon located in the upper part of the bucket body; a compressed air outlet is arranged at the bottom of the bucket body which directly faces the outlet sand pipe, and the wall of the bucket body corresponding to the upper part of he filter bed is thereon provided with a clear water outlet. The invention adopts the fundamental principle of a fluidized bed, and combines the innovated process of self-cleaning and self-returning B metal material; during separation, the machine does not need to be stopped for cleaning, cleaning water is not wasted, and the problem of loose bed is solved simultaneously.

Description

technical field [0001] The invention relates to a separation device, in particular to a self-cleaning iron ion separation device. Background technique [0002] According to the Faraday phenomenon, many B metals (the slag after smelting non-ferrous metals containing a large amount of positive charges, of course, must be screened) can be exchanged with the positive and negative ions in the wastewater, and the ionic structure can be transformed into molecules. Iron ions in wastewater is one of these methods. The technology has been widely used in the water treatment industry at home and abroad, and the effect is also very satisfactory. According to the current equipment that uses B metal to exchange iron ions at home and abroad, mechanical filters and sand filters are generally used. The above two types of equipment are widely used in the water treatment industry at home and abroad because of their low treatment costs. [0003] Faraday electrolysis technology has been widely ...

AI Technical Summary

Problems solved by technology

Therefore, the production must be stopped, and a large amount of clean water is used for backwashing, and the waste water from backwashing must be repeatedly treated, thus increasing the operating cost; in addition, it is not easy to loosen the bed after metal B is agglomerated, and it is often necessary to remove the waste water from the machine. The B metal is taken out and cleaned, which increases the labor cost, and at the same time, continuous production cannot be performed during cleaning, which delays the amount of wastewater treatment
