Rare-earth processing wastewater dosing, separating and purifying integrated device

Abstract

The invention relates to the field of rare earth processing wastewater treatment equipment, in particular to a rare-earth processing wastewater dosing, separating and purifying integrated device. Thedevice comprises a device body, a stirring rod is fixedly mounted on the left side in the device body; a stirring dosing plate is fixedly mounted on the outer side of the upper end of the stirring rod; an impurity separator is fixedly mounted on the right side in the device body; a rotating shaft is fixedly mounted at the lower end of the impurity separator; the inner wall of the impurity separator is in the shape of an inverted circular truncated cone inclining outwards; when the stirring rod rotates, the transmission belt can drive the rotating shaft to rotate together; when the rare earth wastewater subjected to dosing is moved into the impurity separator through the liquid guide pipe; the centrifugal force can be utilized to move upwards along the inclined surface of the inner side ofthe impurity separator to be in contact with a slag blocking filter plate to filter internal impurities, and the slag blocking filter plate is arranged in an inclined arc shape, so that the blocked impurities can continuously enter the slag separation layer along the arc surface under the action of the centrifugal force, and the effect of automatically cleaning the impurities is achieved.

Description

technical field [0001] The invention relates to the field of treatment equipment for rare earth processing wastewater, in particular to an integrated device for dosing, separating and purifying rare earth processing wastewater. Background technique [0002] Rare earths have the reputation of "industrial vitamins", and now they have become extremely important strategic resources. Rare earth elements have been widely used in petroleum, chemical industry, metallurgy, textile, ceramics, glass, permanent magnet materials and other fields. With the advancement of science and technology and continuous breakthroughs in application technology, the value of rare earth oxides will increase. [0003] The main wastewater generated during the processing of rare earths is saponification wastewater, oxalic acid precipitation acid wastewater, carbonate precipitation wastewater, and some wastewater has strong acidity. It is necessary to use drugs to neutralize and meet the pH value requireme...

AI Technical Summary

Problems solved by technology

It is necessary to use drugs to neutralize to meet the pH value requirements, but the mixing efficiency of wastewater and drugs in existing rare earth wastewater treatment devices is low, which reduces the treatment speed of wastewater, and cannot automatically clean and filter when the drug is added and filtered The impurities under the filter will cause the filter device to easily accumulate too much accumulated impurities, which will reduce the filtration speed and further reduce the treatment efficiency of rare earth wastewater
