Waste liquid treatment device for rare-earth metal production

Abstract

The invention discloses a waste liquid treatment device for rare-earth metal production, wherein the upper end of the filtering tank is fixedly connected with a liquid inlet pipe, the upper end of theflow guide pipe is fixedly connected with a water pump, and the lower end of the water pump is fixedly connected with a treatment box, the upper end of the treatment box is fixedly connected with anexhaust pipe, and the right end of the treatment box is fixedly connected with a liquid inlet pipe, the liquid inlet pipe is located below the water tank, and a transfer pipe is fixedly connected to the lower end of the treatment box, the lower end of the transferring pipe is fixedly connected with a collecting box, the lower end of the collecting box is fixedly connected with a motor, and the output end of the motor is fixedly connected with a stirring rod, the right end of the collecting box is fixedly connected with a liquid discharging pipe, and the outer side of the liquid discharging pipe is fixedly connected with a fourth valve. According to the waste liquid treatment device for the rare-earth metal production, the filtering effect is increased, and the waste liquid can be used, sothat the harm of the waste liquid treatment device to the environment and the human body is reduced; meanwhile, the extraction and use of the waste liquid are facilitated.

Description

technical field [0001] The invention relates to the technical field of rare earth metal processing, in particular to a waste liquid treatment device for rare earth metal production. Background technique [0002] With the development of the times, the use of rare earth metals has become more and more extensive, which has given birth to many rare earth metal processing industries. The processing of rare earth metals is very complicated, and a large amount of waste liquid will be generated during the processing process. Contains a lot of possible substances, but there are also a lot of impurities in the waste liquid. [0003] However, in the existing waste liquid treatment devices, the waste liquid is treated to a certain extent and then discharged. It is impossible to extract and reuse the usable substances in the waste liquid, which increases resource consumption, and some rare earth metals will produce Harmful gas, the existing waste liquid treatment device does not handle ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a waste liquid treatment device for rare earth metal production, to solve the problem that the existing waste liquid treatment device proposed in the above background technology is to treat the waste liquid to a certain extent and then discharge it, so the waste liquid cannot be discharged. The extraction and reuse of the substances that can be used in the waste liquid will increase the consumption of resources, and the treatment of some rare earth metals will produce harmful gases. The existing waste liquid treatment device does not have the problem of dealing with harmful gases.
