Box-type calcining furnace

The utility model relates to a box type calcining furnace which comprises a furnace body, a furnace door and a plurality of heating parts, the furnace body and the furnace door form a closed hearth, and the plurality of heating parts are divided into a first heating part group arranged on the side wall of the hearth and a second heating part group arranged between the side walls of the hearth. And a calcining channel for calcining materials is formed between the second heating component group and the bottom of the hearth. Through the second heating component group arranged between the side walls of the hearth, the temperature of the middle part of the hearth is conveniently controlled to be consistent with the temperature of the periphery, so that the temperature in the hearth is uniformly distributed, the stability of the material calcining quality is effectively improved, and the product quality is ensured. 本实用新型涉及一种箱式煅烧炉，其包括炉体、炉门、及加热部件，其中炉体与炉门形成密闭的炉膛，加热部件有多个，且多个加热部件划分为设置在炉膛侧壁的第一加热部件组、设置在炉膛侧壁之间的第二加热部件组，其中第二
