Description

Technical Field

[0001] The utility model relates to the relevant field of thermal cleaning furnaces, in particular to a thermal cleaning furnace door sealing structure. Background Art

[0002] The hot cleaning furnace door is an important part of the hot cleaning furnace. Its main function is to protect the hot cleaner in the furnace from being invaded by cold air from the outside, thereby improving the working efficiency of the hot cleaning furnace. The hot cleaning furnace door is usually composed of refractory materials, thermal insulation materials and metal frames. Refractory materials can withstand high temperatures, thermal insulation materials can reduce heat loss, and metal frames play a supporting and fixing role. The shape and size of the hot cleaning furnace door vary depending on the model, but are usually rectangular or round. The functions of the hot cleaning furnace door are mainly as follows: Maintaining the temperature and pressure in the furnace: The hot cleaning furnace will produce a high temperature and high pressure environment when working, and the furnace door can effectively maintain this environment. Thereby ensuring the normal operation of the heat cleaner; preventing cold air from invading: the furnace door can prevent cold air from the outside from invading the furnace, avoiding lowering the furnace temperature, affecting the efficiency of the heat cleaner and increasing energy consumption; protecting the heat cleaner: the furnace door can protect the heat cleaner from external dust, impurities, etc., thereby extending its service life; improving work efficiency: because the furnace door can maintain the temperature and pressure in the furnace, the heat cleaner can work in the best condition, thereby improving work efficiency.
