Battery pole piece planetary ball milling device

Abstract

The invention relates to the technical field of strategic emerging industries, and discloses a battery pole piece planetary ball milling device. The device comprises a gas conveying pipe, wherein an exhaust pipe is fixedly connected to the middle of an inner cavity of the gas conveying pipe in a sleeved mode, three evenly-distributed gas distribution pipes are connected to the bottom of the gas conveying pipe in a clamped mode, and a top cover is fixedly connected to the bottom of one side of each gas distribution pipe. Through a designed base, an upper shell and a movable ring, a single ball mill tank is sealed, the situation that other parts are damaged at a low temperature due to the fact that the whole ball mill is sealed is avoided; through a designed gas-distributing pipe and a gas collecting pipe, in the rotation and revolution process of the ball mill tank, the gas-distributing pipe can be driven by revolution of the ball mill tank to complete autorotation and is not influenced by autorotation of the ball mill tank; and meanwhile, the gas-collecting pipe can be synchronous with the revolution of the ball mill tank and is not influenced by autorotation of the ball mill tank, so that cooling gas can complete cooling circulation through the gas-distributing pipe and the gas collecting pipe, and the condition of breakage of a cooling pipeline is avoided.

Description

technical field [0001] The invention relates to the technical field of strategic emerging industries, in particular to a planetary ball grinding device for battery pole pieces. Background technique [0002] In the preparation of the battery, the manufacture of the pole piece needs to go through five processes: slurry preparation, slurry coating, pole piece rolling, pole piece cutting, and pole piece drying. For the preparation of the slurry, a planetary The planetary high-energy ball mill crushes and mixes the materials. The planetary high-energy ball mill is equipped with several ball mill tanks that revolve with the turntable and rotate at high speed on the circumference of the rotating disc. Great high-frequency impact and friction for fast fine grinding. [0003] When the material is subjected to high-energy impact and rolling for a long time, the material will undergo repeated processes of deformation, cold welding, crushing, and refinement, which will cause the temper...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies in the use of the existing planetary ball mills proposed in the background technology, the present invention provides a planetary ball mill for battery pole pieces, which is equipped with a separate cooling ball mill tank, and the cooling system is not affected by the revolution and rotation of the ball mill pot. The advantage of the volume change of the inner cavity of the trachea to complete the suction action solves the problems in the above-mentioned background technology that other parts of the ball mill are damaged by the influence of the cooling gas, the rotation and work of the ball mill tube cause the cooling pipe to break, and the amount of cooling gas increases with the working time.
