Detailed Description
The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.
Please refer to fig. 1-2. It should be understood that the structure, ratio, size and the like shown in the drawings attached to the present specification are only used for matching with the content disclosed in the specification, so as to be known and read by those skilled in the art, and are not used for limiting the limit conditions that the present invention can be implemented, so that the present invention has no technical essential meaning, and any structure modification, ratio relationship change or size adjustment should still fall within the scope that the technical content disclosed in the present invention can cover without affecting the function that the present invention can produce and the purpose that the present invention can achieve. Meanwhile, the terms such as "upper", "lower", "left", "right", "middle" and "one" used in the present specification are for convenience of description, and are not intended to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof may be made without substantial technical changes, and the present invention is also regarded as the scope of the present invention.
The utility model provides a high-temperature oven with an improved heating wire, which comprises an oven body 1 and a controller 2 arranged on the side edge of the oven body 1,
wherein the side wall of the oven body 1 comprises an outer layer metal plate and an inner layer metal plate 5, a gap 6 is arranged between the outer layer metal plate and the inner layer metal plate 5,
meanwhile, the device also comprises a high-temperature heating wire 8 which is fixed in the gap 6 through an insulating base 7,
the high-temperature heating wire 8 penetrates out of the inner-layer metal plate 5 through the heating wire lead 9, meanwhile, the high-temperature heating wire 8 is sleeved with a circle of high-temperature-resistant quartz tube 10, and the high-temperature heating wire 8 is completely wrapped in the high-temperature-resistant quartz tube 10.
In this embodiment, the high temperature resistant quartz tube 10 is transparent, so that the working state of the internal high temperature heating wire 8 can be conveniently observed.
In this embodiment, the refractory quartz tube 10 is fixed to the outer metal plate by the insulating base 7.
