Abstract
Description
Technical Field
[0001] The utility model relates to a cleaning device, in particular to a roller kiln cleaning device for sintering sodium iron phosphate. Background Art
[0002] Roller kilns are often used for sintering in the preparation process of sodium iron phosphate. During the sintering process, the powder is placed in a sagger, which is then conveyed by the conveyor rollers of the roller kiln. In a high-temperature environment, the powder is easy to fly out of the sagger, mixed with other foreign matter such as magnetic anomalies, and falls into the kiln to form ash accumulation. Too much ash accumulation in the roller kiln can easily introduce impurities such as magnetic anomalies into the finished product, causing abnormalities in the finished product after sintering, which requires thorough cleaning. The existing roller kiln for sintering sodium iron phosphate has a flat bottom structure, and because the kiln needs to be filled with protective gases such as nitrogen to form a protective atmosphere, the sealing requirements are high, resulting in the inability to open a quick opening to facilitate the discharge of residual impurities inside the roller kiln. The kiln body can only be manually disassembled and the foreign matter can only be cleaned with a vacuum cleaner. This cleaning method is time-consuming and labor-intensive, and cannot guarantee the continuity of production. In addition, the cleaning effect is poor, affecting the quality of the finished product.
