Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery production, in particular to a lithium battery wastewater treatment device. Background Art

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as positive and negative electrode materials and non-aqueous electrolyte solutions. With the development of science and technology, lithium batteries have become mainstream. During the production process of lithium batteries, workers need to recycle and process scrapped lithium batteries, and wastewater will be generated in the process of recycling and processing lithium batteries. In the process of treating lithium battery wastewater, reaction reagents need to be added to mix with the wastewater to react so that the lithium battery wastewater meets the discharge standards. However, the existing lithium battery wastewater treatment equipment cannot add appropriate doses of reaction reagents according to the amount of wastewater when adding reaction reagents.

[0003] After searching, China Patent Publication (Announcement) No. 202222993505.5 discloses a lithium battery wastewater treatment device. This patent controls the processing unit to stop the liquid pump, and can automatically add an appropriate dose of reaction reagent according to the water intake of the wastewater. Although the above patent has the function of controlling the water intake of the reaction reagent, the reaction reagent cannot be added evenly. Since the reaction reagent is usually added directly on the surface of the thick wastewater, it needs to be stirred continuously after addition to be completely mixed, resulting in a long mixing time. In addition, the current wastewater treatment device is not thorough enough when discharging liquid. Since most of the current drainage methods are to allow the solution to be discharged naturally after the drainage valve is opened, and there is often residual solution on the inner wall of the reaction box that takes a long time to completely flow out, resulting in a long natural discharge time. Therefore, it is necessary to design a lithium battery wastewater treatment device. Utility Model Content

[0026] In this embodiment, a motor 8 is installed on the upper surface of the box cover 2 , and the output end of the motor 8 is fixedly connected to the reciprocating screw rod 3 .

[0027] When in use, the motor 8 is started to drive the reciprocating screw rod 3 to rotate, thus achieving a transmission effect.

[0028] In this embodiment, a liquid inlet pipe 9 is fixedly connected to one side of the outer surface of the reaction box 1 near the top, a liquid discharge pipe 10 is fixedly connected to one side of the outer surface of the reaction box 1 near the bottom, and a solenoid valve is provided on the outer surface of the liquid discharge pipe 10.

[0029] When in use, the wastewater is conveniently connected to an external wastewater pipe through the liquid inlet pipe 9, so that the wastewater flows into the reaction box 1. After the wastewater reaction is completed, it passes through the liquid discharge pipe 10, which has the effect of convenient discharge.
