Description

Technical Field

[0001] This utility model relates to the technical field of waste liquid pretreatment devices, specifically an NMP waste liquid pretreatment device. Background Technology

[0002] The NMP waste liquid pretreatment unit is mainly used to treat NMP waste liquid generated during the lithium battery production process. This waste liquid is mainly generated in the positive electrode coating and drying process of lithium batteries. NMP, as a solvent for dispersing binders, volatilizes during the drying process. Through the treatment of this unit, the NMP waste liquid can be converted into recyclable electronic-grade products and returned to the lithium battery production line.

[0003] For example, the NMP waste liquid pretreatment device disclosed in the authorization announcement number CN222286526U includes a base plate, a treatment tank is provided on the base plate, the treatment tank is provided with an inlet, the bottom of the treatment tank is provided with an outlet pipe, the outlet pipe is provided with a control valve, the treatment tank is provided with a cooling mechanism, the treatment tank is provided with a filter plate inside the treatment tank, the filter plate is provided with a slag removal mechanism, the cooling mechanism includes an air cooler, a heat exchange chamber, a spiral plate, an outlet, a baffle and an air outlet, the air cooler is provided on the base plate, the heat exchange chamber is provided on the side wall of the treatment tank, and the spiral plate is provided inside the heat exchange chamber;

[0004] Although it achieves this by setting up a cooling mechanism, turning on the air cooler, and injecting cold air into the heat exchange chamber through the air cooler, the cold air flows upward on the spiral plate through the air pressure of the air cooler. Due to the good heat transfer effect of the inner wall of the heat exchange chamber, this process can allow the cold air to exchange heat with the high temperature in the waste liquid. Then the cold air enters the interior of the treatment tank through the outlet, and further exchanges heat with the temperature of the waste liquid, thus lowering the temperature of the waste liquid. The inclined baffle can prevent the waste liquid from entering the heat exchange chamber. By setting up a slag removal mechanism, turning on the motor, and causing the output shaft of the motor to drive the rotating shaft to rotate, the scraper can rotate on the filter plate, which can discharge solid impurities on the filter plate through the slag outlet. During the rotation of the scraper, the rubber protrusions can clear the filter plate pores and prevent the filter plate from clogging.

[0005] However, this does not solve the problem that existing waste liquid pretreatment devices of this type are generally not conducive to convenient quantitative conveying of materials for reaction, affecting the uniformity of liquid mixing, making it difficult to elastically scrape the inner wall, and making it difficult to conveniently discharge and collect waste liquid, thus affecting the reaction efficiency of the waste liquid pretreatment device. Utility Model Content

[0006] The purpose of this invention is to provide an NMP waste liquid pretreatment device to solve the problems mentioned in the background art, such as the inconvenience of quantitatively conveying materials for reaction, which affects the uniformity of liquid mixing, the inconvenience of elastically scraping the inner wall, and the inconvenience of conveniently discharging and collecting waste liquid, thus affecting the reaction efficiency of the waste liquid pretreatment device.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an NMP waste liquid pretreatment device, comprising a trolley and a water storage tank.

[0008] Preferably, a rotating column is installed at the output end of the servo motor, the rotating column extends into the interior of the water storage tank and is movably connected thereto, and support blocks are symmetrically installed on the surface of the rotating column.

Waterproof electric push rods are movably installed on the side wall of the support block.

[0010] Preferably, the output end of each waterproof electric push rod is equipped with a first shaft, the outside of each support block is provided with a support plate, a second shaft is movably installed at the center of each support plate, the second shaft extends through the support plate to its outside, a third shaft is movably installed at both ends of each support plate, and a second connecting arm is fitted at the end of each third shaft away from the support plate.

[0014] Preferably, the rotating shaft is movably connected to the limiting seat, and a handle is fitted onto the surface of the rotating shaft, with the handle in contact with the buckle.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the waste liquid pretreatment device not only facilitates the quantitative conveying of materials for reaction, improves the uniformity of liquid mixing, facilitates the elastic scraping of the inner wall, but also facilitates the discharge and collection of waste liquid, thereby improving the reaction efficiency of the waste liquid pretreatment device.

[0016] (1) The stepper motor drives the screw to rotate, and the screw drives the ion exchange resin to be conveyed downward. It falls into the water storage tank through the feeding pipe to remove impurities.

The waterproof electric push rod drives the first shaft to move, which in turn drives the support plate, second shaft, first connecting arm, third shaft, and second connecting arm to move. Under the support of the rotating shaft, the first connecting arm and second connecting arm drive the flip plate to rotate around the rotating shaft, so that multiple sets of flip plates can rotate to fully stir the waste liquid inside the water storage tank. This realizes that the waste liquid pretreatment device can conveniently and fully stir the waste liquid, improve the uniformity of liquid mixing, facilitate elastic scraping of the inner wall, and improve the convenience of the waste liquid pretreatment device to fully stir the waste liquid.

[0018] (3) Manually pull the handle to disengage the handle from the buckle. Under the support of the limit seat, the handle drives the rotating shaft to rotate. Under the support of the auxiliary shaft, the rotating shaft drives the valve plate to rotate, so that the valve plate and the valve body open at a certain angle, allowing the waste liquid to be discharged and collected. This facilitates the convenient discharge and collection of waste liquid and realizes the convenient discharge and movement of waste liquid. Attached Figure Description
