Description

Conveyor System for Cathode Material Manufacturing Equipped with Unidirectional Sealing Bearing Block The present invention relates to a conveying facility for manufacturing a cathode material having a unidirectional sealing bearing block, and more specifically, to a conveying facility for transporting a saggar containing a cathode material, wherein the installation and replacement of the bearing can be facilitated and maintenance efficiency can be improved. Cathode materials are a key component responsible for battery capacity and output. The cathode material manufacturing process consists of the following main steps. Raw materials such as lithium, nickel, cobalt, and manganese are precisely weighed and mixed (raw material mixing), the mixed raw materials are heat-treated at a high temperature to produce a positive electrode active material (calcination), and the calcined active material is ground to a uniform size. Subsequently, a coating layer is formed on the surface of the ground active material to improve performance (coating), the coated active material is dried to remove moisture (drying), and the dried active material is classified by particle size (classification). In this process, the RHK kiln is used during the firing stage of the cathode material manufacturing process. Since the RHK heat-treats the cathode material while moving it over rollers, a uniform temperature distribution can be achieved. This is crucial for ensuring the uniformity of the cathode material's quality. Furthermore, it is designed to enable a continuous process, which can improve productivity through uniform heat treatment and continuous production. The RHK kiln is equipped with a conveying facility having conveying rollers, and the rollers serve to convey a trolley on which sacks containing the anode material being fed are placed along a conveying path. Typically, such a conveying system has a pair of frames that form a conveying path. The pair of frames has a certain width and a set length along the conveying path. In the above pair of frames, the ends of the rotation axes are rotatably supported at a front-to-back interval. One of the frames is the driving frame, and the other frame is the driven frame. Inside the drive-side frame, drive gears and drive-side bearings are installed to support one end of the rotating shaft and provide rotational driving force to the rotating shaft. A driven bearing that rotatably supports the other end of the rotating shaft is installed inside the driven frame. The driven bearing is installed in the outer space of a pair of frames, which is the inner space of the conveyor, and is positioned in a certain narrow space. In addition, the driven bearing is secured through headless bolts and fixing bolts. Here, if the conveyor driven side bearing and ceramic are damaged, a problem arises in transporting the base plate on which the saga is seated. Accordingly, the driven side bearing must be replaced. Since the driven side bearing is installed in the inner space of the frame, the headless bolt and fixing bolt must be loosened through the inner space of the frame, and the drive gear and drive side bearing must be removed before the driven side bearing and ceramic can be replaced. Consequently, in the past, there was a problem where the maintenance time increased compared to other sections due to the increase in the number of processes associated with replacing the driven bearing and the difficulty of using jigs and fixtures due to the narrow space.
