Description

Technical Field

[0001] The utility model relates to a device for cleaning and removing water from the inner wall of a quartz furnace tube, belonging to the technical field of quartz furnace tube processing equipment. Background Art

[0002] Quartz furnace tubes are tubular components made of quartz material. They have many characteristics such as high temperature resistance, good chemical stability, good thermal stability, excellent optical properties, and good electrical insulation properties. They are mainly used in various industrial and laboratory fields.

[0003] During the processing of quartz furnace tubes, the inner wall of the tube needs to be frequently cleaned, and then the remaining water stains after cleaning are removed. The existing methods of removing water mainly include natural drying and hot air drying: the natural drying method has the disadvantages of low efficiency and large floor space; hot air drying uses a hot air blower to blow out hot air to heat the air inside the furnace, thereby drying the workpiece inside the furnace. Since the length of quartz furnace tubes reaches 4 meters and some types of quartz furnace tubes are blocked at one end, it is difficult for hot air to reach deep inside the tube. Therefore, hot air drying is not ideal for the inner wall of quartz furnace tubes with a long length and one end blocked. Moreover, when a large amount of water stains remain on the inner wall of the quartz furnace tube, the evaporation of water will precipitate a large amount of hard carbonate scale that adheres to the surface of the quartz furnace tube, affecting product quality.
