一种氧化炉的螺旋进风装置
摘要：
本发明公开了一种氧化炉的螺旋进风装置，包括箱体，箱体的前后两端敞口，其中一端为进风口，另一端为出风口，箱体的中部设有隔板将箱体分割为靠近进风口的送风腔、靠近出风口的调节腔，隔板上设有三根成品字形分布的管体，管体内设有螺旋形的叶片，管体的前端为喇叭形。本发明结构设计新颖，通过在管体内设计螺旋形的叶片，保证进入氧化炉的炉膛内气流经过每个区域，保证了炉膛内气流的均匀性。
摘要（英）：

The invention discloses a spiral air inlet device of an oxidizing furnace. The spiral air inlet device comprises a box body, wherein the front end and the rear end of the box body are opened; one end is an air inlet, and the other end is an air outlet; a baffle is arranged in the middle of the box body and divides the box body into an air feeding cavity close to the air inlet and an adjusting cavity close to the air outlet; three tubes distributed like the Chinese character 'pin' are arranged on the baffle; spiral blades are arranged in the tubes; and the front ends of the tubes are trumpet-shaped. The spiral air inlet device of the oxidizing furnace is novel in structural design; and the spiral blades are arranged in the tubes, so that airflow entering the furnace chamber of the oxidizing furnace passes through each region, and the uniformity of the airflow inside the furnace chamber is guaranteed.
