Description

Technical Field

[0001] The utility model relates to the technical field of thermal reactors, in particular to a high-voltage current-inducing insulating device dedicated to high-frequency agglomeration. Background Art

[0002] The high-voltage lead-in insulation device for high-frequency agglomeration generates current through the high-frequency power supply, which induces high-density current on the surface of the heated workpiece, thereby quickly heating the surface of the workpiece to the required temperature. This heating method can achieve local heating, avoid electrical heating of the entire workpiece, and save energy and time. In thermal reaction technology, this device is often used in processes that require precise temperature control, such as smelting metals and synthetic chemical reactions. In high-voltage lead-in insulation devices, it is crucial to maintain good insulation to prevent current from passing through the tank wall instead of the heated workpiece surface. The design of large-diameter electrode penetrations may make insulation more complicated because it is necessary to ensure that the insulating material can cover the entire penetration and can effectively isolate the current.

[0003] In the prior art, the device directly designs the current lead-in penetration piece inside the tank body, and the electrode penetration piece arranged inside cannot be sealed and insulated, and the insulation and sealing properties cannot be guaranteed. Utility Model Content
