Description

Technical Field

[0001] This invention relates to the field of electric heating tube technology, and in particular to a grinding device and grinding method for the connection of an electric heating tube. Background Technology

[0002] An electric heating element is a tubular electric heating element composed of a metal tube, a spiral resistance wire, and crystalline magnesium oxide powder. Electric heating elements are typically made from high-quality imported stainless steel tubes, imported high-temperature magnesium oxide powder, and high-quality heating wire. Other structural parts are made of stainless steel, resulting in excellent overall performance, a long lifespan, and easy maintenance. The high-temperature resistance wire is evenly distributed within the seamless stainless steel tube, with the gaps filled with crystalline magnesium oxide powder, which has excellent thermal conductivity and insulation properties. This advanced structure not only results in high thermal efficiency and uniform heating, but also ensures that when current flows through the high-temperature resistance wire, the generated heat diffuses through the magnesium oxide powder to the surface of the metal tube and is then transferred to the heated object or air, achieving the heating purpose.

[0003] like Figure 11 The image shows a flange-type electric heating tube, which is assembled from multiple U-shaped electric heating tubes and a flange. When the U-shaped electric heating tubes are connected to the flange, the two end faces of the U-shaped electric heating tubes need to be in close contact with the flange to prevent external heated liquid from flowing into the electric heating tubes. Therefore, the two end faces of the U-shaped electric heating tubes need to be ground to ensure the flatness of the end faces of the U-shaped electric heating tubes.

[0004] However, the grinding equipment currently used can only grind one end face of the U-shaped electric heating tube in actual use. It cannot grind the end faces of two U-shaped electric heating tubes at the same time. Therefore, it cannot be guaranteed that the two end faces will always be flush, which can easily lead to gaps when assembling flange electric heating tubes.

[0005] Furthermore, when grinding U-shaped electric heating tubes, the waste residue produced by grinding is prone to scattering everywhere and cannot be collected in a concentrated manner. On the one hand, the waste residue scattered everywhere is likely to injure the staff, and on the other hand, the scattered waste residue is also inconvenient to collect.

[0006] Therefore, based on the two problems mentioned above, this technical solution proposes a grinding device and grinding method for the connection of an electric heating tube, in order to solve the problems mentioned above. Summary of the Invention
