An integrated device for dosing, separation and purification of rare earth processing wastewater

Abstract

The invention relates to the field of rare earth processing wastewater treatment equipment, in particular to an integrated device for dosing, separating and purifying rare earth processing wastewater, comprising a device main body, a stirring rod is fixedly installed on the left side inside the device main body, and a stirring and dosing plate is fixedly installed outside the upper end of the stirring rod The impurity separation device is fixedly installed on the right side inside the main body of the device, and the rotating shaft is fixedly installed through the lower end of the impurity separation device, and the inner wall of the impurity separation device is set in a rounded table shape inclined to the outside, so when the stirring rod rotates, the rotating shaft can be driven by the transmission belt together. Rotate, so that when the rare earth wastewater that has been added to the drug moves to the inside of the impurity separation device through the catheter, it can use centrifugal force to move up along the slope inside the impurity separation device, and contact the slag blocking filter plate to filter the internal impurities. The slag blocking filter plate is set in an inclined arc shape, so that the blocked impurities can continue to enter the slag separating layer along the arc surface under the action of centrifugal force, so as to achieve the effect of automatic cleaning of impurities.

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
