Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery binder production, and specifically relates to a mixing, stirring and dispensing device for lithium battery binders. Background Technique

[0002] A lithium battery binder is a polymer compound, which is a non-active component in the electrode sheet of a lithium-ion battery and is one of the important materials that must be applied in the preparation of the electrode sheet of a lithium-ion battery.

[0003] In the prior art, in a Chinese patent document with the authorization announcement number CN218609032U, a mixing, stirring and dispensing device for lithium battery binders is recorded. The patent includes legs, and a stirring mechanism is arranged at the top of the legs. The stirring mechanism includes a stirring bin installed at the top of the legs. A fixed column is connected to the bottom of the inner wall of the stirring bin, and a shielding rod is fixedly installed at the top of the fixed column; the lithium battery binder is mixed and stirred by the stirring mechanism. The stirring rod stirs inside the stirring bin in a circular motion, so that the lithium battery binder can be mutually fused inside the stirring bin. A rotating and rising threaded plate is installed on the outside of the shielding rod, which can push the lithium battery binder upward while obstructing it, forming the effect that the lithium battery binder can move up and down inside the stirring bin, making the lithium battery binder fuse more evenly. A water storage bin is installed outside the stirring bin, and water with a lower temperature can be injected into the water storage bin. The heat dissipation plate can accelerate the dissipation of heat in the water. With continuous use, the water contacts the periphery of the stirring bin, making the temperature inside the stirring bin also decrease, ensuring that the temperature does not rise during the stirring of the lithium battery binder.

[0004] In the prior art, by injecting water with a lower temperature into the water storage bin, it only has the function of cooling. However, too low a temperature will affect the fluidity and stirring effect of the slurry, and too high a temperature may cause the solvent to volatilize too fast, affecting the viscosity and uniformity of the slurry. Moreover, the temperature of the water in the water storage bin gradually rises, and the cooling quality is uncertain.

[0005] Therefore, we propose a mixing, stirring and dispensing device for lithium battery binders. Content of the Utility Model
