Description

Technical Field

[0001] The utility model belongs to the technical field of battery processing, and specifically relates to a new energy battery electrolyte impurity processing device. Background Art

[0002] New energy batteries, such as lithium iron phosphate batteries, lithium batteries, and ternary lithium batteries, typically use materials containing lithium as electrodes and are representative of modern high-performance batteries. In used lithium iron phosphate batteries, the positive electrode material is lithium iron phosphate, which contains a large amount of recyclable iron. In used batteries, contact between the electrode material and the electrolyte causes corrosion of the iron, resulting in iron loss. Therefore, recycling iron from used batteries not only reduces environmental pollution but also provides valuable iron resources.

[0003] At present, the existing new energy battery electrolyte impurity treatment device, such as the disclosed invention patent with publication number CN111106406A, discloses a new energy chemical battery recycling and processing device, including a support frame, a processing box and an iron removal component, the upper part of the support frame is fixedly installed with a processing box, the top of the processing box side wall is installed with a feed port, the top of the processing box is connected to a cover plate through a snap mechanism, the middle part of the cover plate is fixedly installed with a working motor, the output end of the working motor is fixedly connected to a first rotating shaft, the bottom of the first rotating shaft is fixedly connected to a stirring component, and two iron removal components for iron removal are symmetrically provided on both sides of the first rotating shaft. Although this solution can quickly separate iron from the electrolyte, iron easily adheres to the iron removal roller. Even if the electromagnet is powered off, some iron will still remain on the iron removal roller, which is inconvenient to remove and affects the next recycling and processing of the electrolyte.

[0004] Therefore, improvements are urgently needed. Utility Model Content

[0005] In response to the above-mentioned defects in the prior art, the utility model provides a new energy battery electrolyte impurity treatment device, including a tank body, a stirring mechanism, an iron removal mechanism and a cleaning mechanism. A feed pipe and an exhaust pipe are provided on the upper part of the tank body, a lower hopper is provided at the bottom of the tank body, and a discharge port is provided at the bottom of the lower hopper. A top cover is sealed and fixed on the top of the tank body, and an observation port is provided on the side wall of the tank body.

[0006] The stirring mechanism includes a reduction motor and a rotating shaft. The reduction motor is arranged outside the tank body, and the rotating shaft is vertically arranged at the center position inside the tank body. The top end of the rotating shaft passes through the top cover and is transmission-connected to the output shaft of the reduction motor. Several stirring blades are installed at the bottom end of the rotating shaft.

[0007] The iron removal mechanism includes a plurality of iron removal cylinders arranged in the tank body, the plurality of iron removal cylinders are evenly distributed around the rotating shaft, and an electromagnet is arranged inside the iron removal cylinder.

[0008] The cleaning mechanism includes an electric cylinder arranged above the top cover and a cleaning disk arranged in the tank body. The piston rod of the electric cylinder passes through the top cover and is fixedly connected to the cleaning disk. The cleaning disk is provided with a number of cleaning holes with the same number as the iron removal cylinders. The several cleaning holes correspond to and match the several iron removal cylinders, and each iron removal cylinder passes through each cleaning hole. Each cleaning hole is provided with bristles, and a through hole for the rotating shaft to pass through is provided in the center of the cleaning disk.

[0009] Optionally, a battery is provided above the top cover, and the electromagnet is circumferentially arranged around the inner wall of the iron removal cylinder. The top of the iron removal cylinder is fixedly connected to the bottom surface of the top cover through an insulating tube, and a wire is passed through the insulating tube, and the electromagnet is electrically connected to the battery through the wire.

[0010] Optionally, the length of the rotating shaft is greater than the sum of the lengths of the iron removal cylinder and the insulating tube, and the stirring blades are located below the iron removal cylinder.

[0011] Specifically, when the rotating shaft drives the stirring blade to rotate, no interference is caused to the iron removal drum.

[0012] Optionally, supporting legs are provided below the tank body.

[0013] Optionally, a heating jacket is provided on the outer wall of the tank.

[0014] Specifically, the heating jacket is used to heat the tank body.

[0015] Optionally, a discharge valve is provided at the discharge port of the tank body.

[0016] In particular, the discharge valve facilitates controlled discharge.

[0017] The present invention also includes other components that enable the normal operation of a new energy battery electrolyte impurity treatment device, all of which are conventional technical means in the field. In addition, devices or components not otherwise specified in the present invention all employ conventional technical means in the field, such as electric cylinders, reduction motors, and batteries.

[0018] The working principle of the utility model is that when in use, the electrolyte is put into the tank body through the feed pipe, the battery is connected to power the electromagnet, and the reduction motor is started at the same time to drive the rotating shaft to rotate, which drives the stirring blade to rotate, and then slowly stirs the electrolyte in the tank body, so that the electrolyte circulates and contacts the iron removal cylinder, and the iron in the electrolyte is adsorbed on the iron removal cylinder, thereby accelerating the iron removal efficiency. After the treatment is completed, the discharge valve is opened to discharge the electrolyte, and the inside of the tank body is dried. At the same time, the battery is disconnected to cut off the power to the electromagnet, and most of the iron will be removed by gravity. The iron will fall into the lower hopper, but some iron will still adhere to the iron removal cylinder and be difficult to remove. At this time, the electric cylinder can be controlled to stretch the piston rod to drive the cleaning plate to move downward. In the process of the cleaning plate moving downward, the bristles in the cleaning hole will sweep the surface of the iron removal cylinder to clean up the iron on it. Then, the electric cylinder can be controlled to retract the piston rod and pull the cleaning plate upward to clean the iron removal cylinder again. This operation is repeated until the iron on the surface of the iron removal cylinder is cleaned up. The cleaned iron is finally collected in the lower hopper and discharged centrally.

[0019] The beneficial effect of the utility model is that the iron removal efficiency of the electrolyte can be accelerated through the tank body, the stirring mechanism and the iron removal mechanism; the iron adhering to the surface of the iron removal cylinder can be swept down through the cleaning mechanism, which is convenient for cleaning and provides convenience for the next recovery and treatment of the electrolyte.
