[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0019] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0020] like Figures 1-4 As shown, a ceramic fixture for a heating wire comprises a fixture 1, with a first connection end 2 and a second connection end 3 formed on either side of the fixture 1. Adjacent fixtures 1 have first and second connection ends 2 and 3 adapted to each other. Furthermore, adjacent fixtures 1 define positioning holes 4 on the connecting side. These positioning holes 4 are waist-shaped holes through which the heating wire passes, limiting its deformation during heating to within the waist-shaped hole. Preferably, the fixture 1 is made of ceramic.

[0021] Among them, the first connection end 2 and the second connection end 3 are formed at the upper part of the corresponding side of the fixing part 1, and the positioning hole 4 is defined at the lower part of the side of the connection of the fixing part 1. When installed and used, the heating wire passes through the corresponding positioning hole 4, and the adjacent first connection end 2 and second connection end 3 are adapted and plugged in on the outside of the heating wire spiral circle.

[0022] In some preferred embodiments, multiple fixing portions 1 are connected via matching first connecting ends 2 and second connecting ends 3 to form a fixing unit of predetermined length. Accordingly, the fixing unit is a ceramic fixing unit, and the fixing portion 1 at the end of the fixing unit includes a corresponding first connecting end 2 or second connecting end 3. Specifically, the first connecting end 2 and the second connecting end 3 are respectively matched with a dovetail groove 5 and a buckle 6, and a predetermined sliding damping is provided between the buckle 6 and the inner wall of the dovetail groove 5.

[0023] The specific usage is as follows: multiple fixing parts 1 are connected by dovetail grooves 5 and buckles 6 to form a fixing unit with a predetermined length. The fixing unit fixes the heating wire along the axial direction of the heating wire. The spiral turns of the heating wire pass through the corresponding positioning holes 4 respectively. The positioning holes 4 are the deformation space of the heating wire. The deformation of the heating wire can be reduced by the fixing unit.

[0024] For example, the heating wire (φ8.25mm) used in the heating furnace (high-temperature oxidation furnace VM890, Chuangxin Thermal Ceramic Furnace (Changzhou) Co., Ltd.) uses full-length rows of fixing units on both sides of the terminal blocks connected to the heating wire, that is, the spliced ​​fixing part 1 forms a fixing unit extending to both ends of the heating wire, and the heating wire is fixed along the length direction of the heating wire; the bottom of the lower combustion zone of the heating furnace generates the most heat and has the largest heat loss, so a short row of ceramic fixing units is added at the bottom, increasing the length from 206.5mm to 284mm, and a short row of fixing ceramics is added at the top of the upper combustion zone of the heating furnace, increasing the length from 138.5mm to 185mm, to control the deformation of the heating wire.

[0025] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents. In short, if those skilled in the art are inspired by this, and without departing from the purpose of the invention of the present invention, they can design structural methods and embodiments similar to the technical solution without creativity, and they should all fall within the scope of protection of the present invention. Each component of the present application can be driven by a corresponding external motor, which is a prior art and will not be described in detail in this application.
