Description

Technical Field

[0001] The utility model relates to the technical field of refractory furnaces, in particular to a refractory furnace which is convenient for replacing a furnace core. Background Art

[0002] A refractory furnace is a device used for high-temperature heating or combustion. It is made of refractory materials and can withstand high temperatures and chemical corrosion. Refractory furnaces are usually used in smelting, sintering, calcining and other process processes in industrial production.

[0003] The furnace core is an important part of the refractory furnace. It is in contact with the burning or heating material and withstands high temperature and chemical corrosion. Due to long-term use and high temperature environment, the furnace core will gradually wear and age, resulting in performance degradation or failure. In order to ensure the normal operation and safety of the refractory furnace, the furnace core needs to be replaced regularly. For example, the Chinese utility model patent with patent publication number CN217737889U includes a device body, and the device body includes a refractory furnace body. The patent can be provided with a first clamping column, a first clamping groove, a second clamping column and a second clamping groove. The adoption of this design brings about that in actual use, the furnace core body of the device is not rigidly fixed, but the first clamping column, the first clamping groove and the second clamping column and the second clamping groove are mutually engaged to complete the positioning and fixing of the furnace core body, which not only ensures the stability of the installation of the furnace core body, but also facilitates the subsequent replacement of the furnace core body. Although the patent can use the clamping column and the clamping groove to facilitate the installation of the furnace core, when disassembling, since the furnace core is located inside the refractory furnace and fits with the inner wall of the refractory furnace, it is necessary to use tools to fix the furnace core and lift it out during disassembly, but due to the small internal space of the refractory furnace, it is inconvenient to use tools to fix it. In view of this, we propose a refractory furnace that is easy to replace the furnace core. Utility Model Content
