With the rise and rapid development of the lithium battery industry, the demand for high-purity NMP in power batteries, energy storage batteries and other fields is increasing, and the requirements are gradually increasing; the existing NMP distillation waste will be discharged through the pipeline to the treatment place, and then the next step will be carried out, but the existing treatment place is usually far away from the NMP distillation location, and when the processing capacity of a treatment box is insufficient, it is necessary to wait for the treatment to be completed before transmission, which will cause a waste of resources. In order to solve the above problems, a waste recovery device for NMP distillation is proposed. Utility Model Content

[0004] Furthermore, the turntable is connected to an external controller, there are two processing boxes, which are symmetrically arranged at both ends of the slide, and the support plate is located in the middle of the slide and fixed in the slide;

[0005] Furthermore, electric push rods are fixedly provided on both sides of the support plate, and a limit ring is fixedly provided on the other end of the electric push rod, the limit ring is sleeved on the processing box, the electric push rod is connected to an external controller, and the contact port is coupled to the input pipe.

[0006] Beneficial effects of the utility model:

[0007] The utility model controls the electric push rod on one side to extend first, drives the limit ring and the processing box to move outward along the slide slot, so that the contact port is combined with the input pipe on the distillation tower, and the waste of NMP distillation is processed and recycled. When the processing box is full, the electric push rod on this side is retracted to separate the processing box and the input pipe, and the rotation of the turntable is controlled to make the contact port of the other processing box face the input pipe to repeat the above operation, and the replacement is completed. When the processing capacity of one processing box is insufficient, it is not necessary to wait for the processing to be completed before transmission, thereby reducing resource waste.
