Description

Technical Field

[0001] This utility model relates to the field of sponge zirconium processing technology, specifically to a passageway heater device for sponge zirconium. Background Technology

[0002] In the production process of sponge zirconium, the aisle heater device plays a crucial role. However, traditional aisle heater devices present numerous problems when applied to sponge zirconium production.

[0003] First, the heating efficiency was low. Early heaters could not heat the materials in the aisle quickly and evenly, which led to longer production cycles, reduced production efficiency, and increased time costs for enterprises.

[0004] Secondly, the temperature control accuracy is poor. The production of sponge zirconium has extremely stringent temperature requirements, but the old aisle heaters are unable to accurately maintain a stable heating temperature, resulting in large temperature fluctuations, which reduces the product quality of sponge zirconium and causes economic losses to enterprises.

[0005] Furthermore, energy consumption is high. Traditional equipment has low energy efficiency, resulting in significant energy waste during the heating process. This not only contradicts the current development concept of energy conservation and environmental protection but also increases production costs for enterprises. In addition, the equipment lacks stability and reliability. Due to limitations in structural design and material selection, these aisle heaters are prone to malfunctions during long-term operation, requiring frequent shutdowns for maintenance and severely impacting production continuity.

[0006] To address the aforementioned issues, a passageway heater device for sponge zirconium is designed to better meet practical application needs. Utility Model Content

[0007] The purpose of this invention is to provide a passageway heater device for sponge zirconium to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a passageway heater device for sponge zirconium, comprising a protective layer, an insulation layer fixed to the inner wall of the protective layer, a heating cavity fixed to the inner side of the insulation layer, the heating cavity being fixed to a conductive rod, the conductive rod being connected to a resistance wire, and the resistance wire being fixed inside the heating cavity.

[0009] Preferably, the heating chamber is made of carbon fiber reinforced silicon carbide composite material, and the thickness of the heating chamber is 0.5mm-1mm. By limiting the material of the heating chamber, the stability of the heating chamber in long-term high-temperature environment is ensured.

[0010] Preferably, a temperature and pressure detector is installed on the protective layer and is connected to the heating cavity. The protective layer is fixed to the passage assembly. The temperature and pressure detector can detect the temperature and pressure inside the heating cavity.

[0011] Preferably, a flow detector is fixed on the passage component, and the passage component is installed inside the heat transfer pipe. The flow detector can monitor the flow velocity of the sponge zirconium flowing inside the passage component.

[0012] Preferably, a temperature sensor is fixed on the heat transfer pipe, which can monitor the internal temperature of the heat transfer pipe.

[0013] Preferably, the diameter of the heat transfer pipe is larger than the diameter of the passageway assembly. By limiting the size of the heat transfer pipe, the normal flow of hot air is ensured, thereby ensuring the heating effect of the sponge zirconium in the passageway assembly.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The sponge zirconium aisle heater device uses an aisle heater and component aisle to connect the sublimation furnace and the reduction furnace. The flow detector can adjust and control the amount of gaseous zirconium tetrachloride entering at any time. After the heater is working, the zirconium tetrachloride in the sublimation liner can be heated and sublimated into gaseous state. The gaseous zirconium tetrachloride enters the reduction liner through the aisle component heated by the aisle heater and undergoes a magnesothermic reduction reaction with liquid magnesium, completing the reduction production stage of sponge zirconium, improving the production efficiency of sponge zirconium, reducing energy consumption, and realizing continuous and efficient production of sponge zirconium.
