Embodiment Construction

[0025] figure 1 A schematic diagram showing a water tank in a chip removing device according to the present invention. The water tank 1 is provided with a net plate 11 near the bottom, and the net plate 11 is supported on the bottom plate of the water tank by several pads 12 . The mesh plate 11 is a perforated plate with holes for the passage of wash water (usually distilled or deionized water). Obviously, the mesh panel 11 can also be a metal mesh, as long as it has the required strength and rigidity. The mesh plate 11 is used as a device to support the electrode material, so that the electrode material (take carbon felt as an example below) can be "suspended" in the water tank. The distilled water or deionized water flowing through the surface of the carbon felt can pass through the mesh plate downwards and flow out through the water outlet. In this context, the term "suspension device" is used to refer to the mechanism that supports the carbon felt so that all sides of t...

Abstract

The invention provides a method and a device for removing fragments in an electrode material, which fills the blank of a special device and method for washing electrode materials in the prior art. The method comprises the following steps of: suspending the electrode material in a water tank; supplying circulating water to the water tank; and filtering the fragments in the circulating water by a filter. The device comprises a water tank, a suspension device and a circulating pump, wherein at least one water inlet is formed in the wall of the water tank or a water tank cover, and at least one water outlet is formed in the bottom of the water tank; the suspension device is arranged in the water tank and is used for suspending the electrode material in the water tank; and the circulating pump is used for circulating washing water. The method and the device have an obvious fragment removing effect, do not cause damages to the electrode material, can be used for processing electrode materials with different sizes synchronously so as to achieve mass processing, and are simple to operate.

Description

technical field [0001] The invention relates to an auxiliary equipment and production method for producing secondary batteries, in particular to a method and device for removing debris from electrode materials (usually carbon felt and graphite felt). Background technique [0002] Secondary batteries, such as zinc-bromine flow batteries and all-vanadium flow batteries, often use carbon felt or graphite felt as electrode materials, which is due to the good conductivity, oxidation resistance, high activity and mechanical strength of graphite felt / carbon felt . Carbon felt is usually made of polyacrylonitrile-based raw silk (fiber filament) through needle punching, and then pre-oxidized and carbonized. After further graphitization process, graphite felt is obtained. [0003] During the carbonization and graphitization process of graphite felt / carbon felt, the fiber filaments undergo high-temperature treatment, the mechanical strength will deteriorate, and even the fiber filame...
