An electric heating rotary furnace, including furnace tube, thermocouple protective tube, feeding port, outlet port and small feeder board, feeding mouth and outlet are located at both ends of the inclined furnace barrel, the feeding port is end to the top of the furnace barrel, the thermocouple protective tube is located in the shaft of the furnace tube and runs through the furnace barrel, and the small feeder board is placed on the inner wall of the furnace tube and is uniformly distributed along the inner wall of the furnace tube for a week, and the casing is uniformly distributed along the inner wall of the furnace tube. Sleeve is set outside the thermocouple protective tube, the casing is divided into multiple sections along the furnace tube, and the large lifting plate is set in the furnace tube. The large lifting plate is set on the radial surface of the furnace tube, one end of the furnace tube is connected with the inner wall of the furnace tube and the other end is connected with the casing. The large lifting plate is divided into four pieces with 90 degrees each other, and the inner area of the furnace barrel is divided along the circle on Thursday; the large feeder board is carried out. In the middle, the small lifting plate is parallel to the axis of the furnace tube, and the number of rolling of the material is obviously increased, the quality of the roasting is improved, the calcination time is shortened, and the material is reduced, so it is suitable for the production of the fragile material.

一种电加热回转炉
本技术涉及一种电加热回转炉,属于催化剂加工领域。
技术介绍
当前,制备催化剂载体和成品通常采用高温焙烧的工艺。成型的干燥条主要成分为氢氧化铝进入焙烧炉经过高温焙烧,制备成所需的氧化铝载体。通常,载体高温焙烧是在焙烧炉里完成的。现有的焙烧炉根据形式可分为回转炉、辊道窑、网带窑等,根据加热方式可分为燃气加热和电加热。电加热回转炉利用进料口与出料口倾斜的角度以及炉筒旋转完成进出料,炉筒内的物料随炉筒内的扬料板翻转,与炉筒内流通的空气接触,完成载体焙烧。缺点是炉筒内的物料在扬料板的带动下,会出现摔落断条的情况,特别不适用于易碎物料的焙烧。
