Description

Technical Field

[0001] The utility model relates to the technical field of ceramic sheets, in particular to a combined bolt for welded wear-resistant ceramic sheets. Background Art

[0002] Ceramic sheet is a sheet-like object made of ceramic material. The main components of ceramic material include silicon oxide, aluminum oxide, potassium oxide, sodium oxide, calcium oxide, magnesium oxide, iron oxide, titanium oxide, etc. Common ceramic raw materials include clay, quartz, potassium sodium feldspar, etc. Ceramic sheet has a wide range of applications in various fields due to its unique physical and chemical properties. Wear-resistant ceramic sheet is often used in parts that need to resist wear, such as in some conveying pipelines, the inner wall of reactors, etc., usually connected with glue or bolts.

[0003] The utility model patent application document with publication number "CN201281066Y" discloses a combined bolt for welded wear-resistant ceramic sheets, which solves the defect of existing welded wear-resistant ceramic sheets that the welding holes are easily worn after installation and welding. The bolt is composed of two parts, the lower part is a cylindrical metal with an external thread on one end, and the upper part is a nut made of high alumina material. Its shape is determined by the shape of the welding hole, and it can be conical or cylindrical, with an internal thread on one end; when the ceramic sheet is welded and installed, the metal non-threaded end is welded to the steel plate substrate, the ceramic sheet is put on, and then the high alumina nut is screwed onto the metal column to combine them together. Because the nut is also made of high alumina material, the wear resistance on the welding hole surface is also relatively good, and it is easy to install.

[0004] The combined bolts for welded wear-resistant ceramic sheets disclosed in the above-mentioned document have the following defects: this technical solution cannot perform partial replacement after key components are damaged. For example, if the threaded part of the bolt is damaged due to repeated tightening and loosening, the entire bolt needs to be replaced, which not only increases the cost, but the replacement process may also be more complicated, requiring the dismantling of the entire fixed structure, affecting the normal use cycle of the equipment.

[0005] It can be seen from this that the existing combined bolts for welded wear-resistant ceramic sheets do not have a structure that allows partial replacement of the bolts. It is necessary to improve the existing deficiencies and provide a combined bolt for welded wear-resistant ceramic sheets. Utility Model Content
