Abstract

A sprocket for a kiln conveyor and a wear inspection system thereof are disclosed. A sprocket for a kiln conveyor according to one embodiment includes a first sprocket body portion to which an axis is connected by penetrating the center, and a second sprocket body portion that surrounds the outside of the first sprocket body portion and contacts and frictionally contacts a conveyor chain. The second sprocket body portion may be made of a material that does not affect magnetic foreign matter in a product sintered inside the kiln upon wear, and can easily confirm and inspect the wear of the sprocket and prevent the generation of magnetic foreign matter caused by the wear of the sprocket.

Description

Sprockets for kiln conveyors and their wear inspection apparatus The present invention relates to a sprocket for a kiln conveyor and a wear inspection system thereof, and more specifically, to a sprocket for a kiln conveyor and a wear inspection system thereof that can verify and inspect the wear of the sprocket for a kiln conveyor and prevent product defects of anode materials by using a material that can prevent magnetic foreign matter in wearable parts. Unlike primary batteries, which cannot be recharged, secondary batteries refer to batteries that can be charged and discharged. A secondary battery can be composed of a cathode material, an anode material, an electrolyte, and a separator. Among these, the cathode material is an important component that determines the performance of the secondary battery, such as capacity and output. Calcination is a process of adding lithium, the core material of lithium-ion batteries, to a precursor made of cathode material constituents such as nickel, cobalt, and manganese. A high-temperature atmosphere is stably formed inside the kiln, and the raw material is uniformly placed in a firing vessel, such as a saggar, and transported, and can be sintered through a firing process. A kiln conveyor is a device that moves a firing vessel in a set direction. Generally, a kiln conveyor may consist of a conveyor chain and a sprocket connected to the conveyor chain that rotates. Additionally, wear may occur on the sprocket due to contact friction with the conveyor chain. However, conventional sprockets for kiln conveyors had a problem in that, due to the material properties, wear generated magnetic contaminants, ultimately causing product defects in the anode material. Furthermore, while these conventional sprockets require inspection and replacement planning based on wear, there were difficulties in inspecting and verifying the wear status of sprockets while they were in operation. As a prior art document related to the present invention, there is Korean Published Patent Application No. 10-2005-0118928, which discloses technology related to a conveyor sprocket. FIG. 1 is a drawing showing a schematic front structure of a sprocket for a kiln conveyor according to one embodiment.
