The extraction process of praseodymium and neodymium oxide will generate a large amount of wastewater and contain a large amount of acidic substances and heavy metal substances. If it is directly discharged into the sewage Pipelines will cause serious pollution to the environment, so it is necessary to recycle acidic substances and heavy metal substances before discharging waste water. At present, most of the treatment processes for heavy metal acid wastewater use the method of "neutralization, precipitation, and filtration". Correspondingly, the wastewater needs to go through sedimentation equipment, filtration equipment, etc. during the recycling process. The principle is to add alkali to the wastewater Active agents make heavy metal ions form hydroxide precipitates, and the precipitated solid particles are discharged and collected after passing through the sand filter, and the precipitated wastewater is discharged out of the recovery device after multiple follow-up operations.

Chinese patent application CN115784333A discloses a heavy metal acid wastewater recovery device for the extraction of praseodymium and neodymium oxide.

The second rotary driver 8414 is preferably a servo motor, and the winding drum 71 on the filter winding belt 7 is placed on the first elastic expansion frame 8413 of the rotation mounting base 841 and the second elastic expansion frame 8424 of the traction mounting base 842. The elastic expansion frame 8413 and the second elastic expansion frame 8424 can be effectively elastically expanded and positioned to place the winding drum 71. When the filter surface of the filter winding belt 7 needs to be replaced, the shutter valve 4 is closed so that the sewage cannot circulate, and the telescopic butt joint 82 shrinks and stops Press to make the filter winding belt 7 movable, and the spring 834 on the fixed mount will still press the moving mounting frame 832 when the telescopic butt joint 82 shrinks, so that the pressing gear 836 on the installation shaft 835 is still in line with the limit of the filter winding belt 7 When the anti-slip side 73 is in conflict, the servo motor drives the installation shaft 835 to rotate, and when the installation shaft 835 rotates, it drives the pressure gear 836 to rotate, and the rotation of the pressure gear 836 will drive the limit anti-skid side 73 of the filter winding belt 7 to the limit clamp rail 812 Move in the middle, make the filter winding belt 7 adjust and switch, the winding drum 71 installed on the traction mounting seat 842 will rotate when the filter winding belt 7 is pulled, so that the unused filter winding belt 7 is expanded to replace the filter surface, The second rotating seat 8423 in the traction mounting seat 842 can increase the resistance by resisting the friction tooth 8422 of the second fixed seat 8421 through the elastic resisting tooth 8425, so as to prevent the winding drum 71 installed on the second elastic expansion frame 8424 from rotating , when the pressure gear 836 pulls the filter winding belt 7 to move, the rotating mounting base 841 drives the first rotating base 8412 to rotate synchronously through the servo motor, so that the winding drum 71 installed on the first elastic expansion frame 8413 rotates and winds. The used filter winding belt 7 is collected and processed, the pressing gear 836 stops rotating, and when the winding drum 71 stops thereupon, the first elastic expansion frame 8413 continues to rotate and then frictionally slides on the winding drum 71 . Effective positioning and winding of the filter winding belt 7 improves replacement efficiency.

Specific working principle:

The staff installs the fixed installation pipe 3 at the water outlet of the sewage treatment equipment 1. When the praseodymium and neodymium oxide is extracted, a large amount of polluted waste water will be generated. When the waste water needs to be treated, the waste water is transported to the sewage treatment equipment 1, and the sewage treatment equipment 1 passes through After the liquid medicine is mixed with the waste water, let the waste water stand still in the body for a period of time, so that the impurities in the waste water can be quickly precipitated, and then the waste water needs to be removed, and the shutter valve 4 is opened, and the waste water in the sewage treatment equipment 1 will pass through the fixed installation pipe 3, The shutter valve 4, the limit mounting frame 5, the rotary cleaning mechanism 6, the filter winding belt 7 and the winding switching device 8 then flow into the drainage pipe 2, and the drainage pipe 2 transports the sewage to the area to be treated. When the sewage flows out, it is filtered and collected. The tape will filter the wastewater. Even if the wastewater is mixed with chemicals to precipitate the impurities in the sewage, there will still be a small amount of impurities in the sewage when it flows, which will be filtered by the filter tape. Long-term filtration by the filter tape will cause a large amount of impurities to adhere On the surface of the filter take-up belt, the rotary cleaning mechanism 6 will rotate when the sewage circulates, and the self-rotating rotary cleaning mechanism 6 can effectively rotate and clean the surface of the filter take-up belt 7 to ensure the circulation of the waste water, and the filter take-up belt 7 After the filter has been used for a period of time, it still needs to be replaced regularly to ensure the filtering effect and smoothness of the filter. When the filter winding belt 7 needs to be replaced, the shutter valve 4 will be closed and the sewage will not be able to circulate. The winding switching device 8 will automatically rotate and switch the filter winding belt 7 , the filter surface of the filter rewinding belt 7 is replaced, and the water receiving bucket 9 is used to receive the waste water spilled during the replacement, effectively saving manpower, improving work efficiency, and ensuring the good condition of the staff's health.
