Furnace body structure of energy-saving type preheating furnace

Abstract

The invention discloses a furnace body structure of an energy-saving type preheating furnace. The furnace body structure comprises a preheating furnace body. A plurality of preheating cavities are formed in the preheating furnace body, and the side walls of each preheating cavity are provided with air inlets. An air return opening is formed in the rear wall of the preheating furnace body. The air inlets are provided with wind shields, and the wind shields can move left and right in guide grooves of the upper inner walls and the lower inner walls of the air inlets. Each preheating cavity is provided with a drawer-type storage box, and each storage box body is further internally provided with a roller. Through holes are evenly distributed in the side walls of the rollers. The two ends of each roller are connected with rotating shafts. One ends of the rotating shafts are connected with inner side bearing pedestals, and each inner side bearing pedestal is coated with a thermal insulation layer. The other ends of the rotating shafts penetrate through drawer panels and are connected with outer bearing pedestals and motors arranged outside the drawer panels. The front face of each drawer panel is provided with a mounting box body. Each mounting box body is further internally provided with a fan. Each drawer panel is made of a thermal insulation material. The furnace body structure is uniform in preheating and long in service life.

Description

technical field [0001] The invention relates to the field of preheating furnaces, in particular to a furnace body structure of an energy-saving preheating furnace. Background technique [0002] At present, most of the equipment used for component preheating in large and medium-sized chemical fiber industries are well-type preheating furnaces, box-type preheating furnaces, and small horizontal preheating furnaces, which generally have uneven temperature, high operating strength, and poor sealing performance. , high energy consumption, and small application range. For components with high preheating requirements or large batches and large volumes, the use effect is poor. At the same time, the existing preheating furnace does not preheat the workpiece uniformly. Contents of the invention [0003] The object of the present invention is to provide a furnace body structure of an energy-saving preheating furnace in order to overcome the above problems. [0004] In order to achie...
