Technical Field

[0002] In modern industrial production, many fields such as metallurgy, chemical engineering, ceramics, and machining place stringent demands on the efficiency, stability, and precision of heating processes. Silicon carbide rods, as a novel non-metallic heating element, have emerged in the industrial heating field due to their significant advantages. Made primarily from high-purity green hexagonal silicon carbide through high-temperature recrystallization, they possess characteristics such as high temperature resistance, strong oxidation resistance, good thermochemical stability, high power density, and rapid heating. They can operate stably for extended periods in high-temperature environments, effectively improving heating efficiency. Therefore, they are widely used in various high-temperature heating equipment. Spiral silicon carbide rod heating element devices, by designing the silicon carbide rod into a spiral structure, further increase the heating area. Compared to straight silicon carbide rods, they can provide higher heating power within the same space, improving heating efficiency and uniformity, and to a certain extent meeting the needs of some industrial production. Therefore, a high-efficiency spiral silicon carbide rod heating element device is needed.

[0003] Existing spiral high-efficiency silicon carbide rod heating element devices are mostly integral structures. If a part is damaged, the whole device often needs to be replaced, which increases maintenance costs and downtime. They are also not convenient for automatically compensating for the thermal expansion difference between the silicon carbide rod and the connecting parts when the temperature changes. Therefore, there is an urgent need for a spiral high-efficiency silicon carbide rod heating element device. Utility Model Content

They are also not convenient to automatically compensate for the thermal expansion difference between the silicon carbide rod and the connecting parts when the temperature changes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a spiral high-efficiency silicon carbide rod heating element device, comprising a spiral silicon carbide rod, wherein the outer wall of the spiral silicon carbide rod is in contact with a beryllium bronze spring sheet, the outer wall of the beryllium bronze spring sheet is in contact with a first fixing frame, the inner wall of the first fixing frame is equipped with a connecting rod, the outer wall of the connecting rod is fixedly connected with a fixing sleeve, and the outer wall of the connecting rod is equipped with a second fixing frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model uses beryllium bronze spring sheets to resist the spiral silicon carbide rod. When using the device, the beryllium bronze spring sheets adapt to the thermal expansion difference between the silicon carbide rod and the connecting parts by utilizing their elastic deformation capabilities during temperature changes. When the spiral silicon carbide rod expands, the beryllium bronze spring sheets are compressed and store elastic potential energy; when it contracts, the beryllium bronze spring sheets release elastic potential energy, achieving elastic connection compensation. The beryllium bronze spring sheets can maintain stable mechanical properties at high temperatures, making them suitable for use in high-temperature conditions.
