Description

Technical Field

[0001] The utility model relates to the technical field of ceramic tubes, in particular to a reinforced alumina ceramic tube. Background Technique

[0002] The heating element can be applied to electric water heaters, cabinet appliances, solar products and electric heating equipment. Due to its high efficiency, good safety and large power, the alumina ceramic heating element is becoming more and more popular among people. The patent document with the publication number of CN217160045 U discloses a reinforced alumina ceramic tube. The two ends of the alumina ceramic tube body are open and internally connected. Internal threads are provided on the inner tube walls at both ends of the alumina ceramic tube body. Reinforced cone ceramic linings are screwed into both ends of the alumina ceramic tube body. Both ends of the reinforced cone ceramic lining are open and internally connected. The outer port of the reinforced cone ceramic lining is larger than the inner port of the reinforced cone ceramic lining. Explosion-proof corrugations and a plurality of heat-permeable openings are also provided on the surface of the reinforced cone ceramic lining.

[0003] When reinforcing the ceramic tube in the above technical solution, only the inner lining is added inside. Since the outside of the ceramic tube is relatively fragile and the technical solution does not add an outer protection device, it is possible that the outside of the ceramic tube is damaged due to collision. Therefore, we propose a reinforced alumina ceramic tube to solve this problem. Content of the Utility Model

And during this process, the first spring 10 is compressed and the second spring 16 extends. At this time, rotate the bolt 19 so that the stop block presses the first frame 17 tightly. At this time, the fixation between the first shell 2 and the second shell 3 is completed. When it is necessary to disassemble the first shell 2 and the second shell 3, only need to rotate the bolt 19 in the reverse direction so that the stop block no longer abuts against the first frame 17. At this time, under the reverse acting force of the first spring 10 and the second spring 16, the second column 12 leaves the clamping plate 21. At this time, the fixation between the first shell 2 and the second shell 3 is released.
