,具体涉及一种电窑对流传热装置。
技术介绍
对加工成型的泥坯进行窑炉烧制是陶瓷生产中的关键环节,直接决定了陶瓷成本的质量。现有技术中通常建设大型窑,采用集中供热和通风,并且对统一规格的泥坯进行传送带或辊轮输送,实现对陶瓷品的大批量工业生产。但是,在大批量单一规格生产以外的场合,往往也需要实现个性化定制产品的加工,例如对消费者自己制作的泥坯进行烧制,或者对个人定制陶瓷仿真头像人偶进行烧制。如果使用现有技术中大型窑生产定制产品,一般只能凑满足够数量的泥坯后再执行加工,这导致出货周期显著拉长;相反,如果在不足量的情况下运转大型窑,就会造成比较大的成本消耗,甚至造成亏损。现有技术中针对个性化定制产品加工的另一种方案是采用小型电窑,实现单体陶瓷品的烧制。现有的小型电窑其加热主要采用在窑内壁上设置电热丝,直接通过电热丝对窑内进行整体加热,但这种方式导致窑内温度不均衡,靠近电热丝的位置温度较高,电热丝之间的缝隙相对的空间温度又较低,导致烧制的产品质量参差不齐。
