Preheating furnace with uniform preheating function

Abstract

The invention discloses a preheating furnace with an uniform preheating function. The preheating furnace comprises a shell, a door plank, a preheating furnace body and a heating box. Multiple preheating cavities are formed in the preheating furnace body. A drawer type containing box is arranged in each preheating cavity. Containing box protruding blocks are correspondingly arranged on the left end side face and the right end side face of each containing box body. Wind shields are correspondingly arranged on air inlets in the left side wall and the right side wall of each preheating cavity. The rear ends of the wind shields are connected with springs. The upper ends and the lower ends of the wind shields are embedded into guide grooves in the upper inner walls and the lower inner walls of the air inlets. A valve plate protruding block is arranged on the inner side face of each wind shield. Through the wind shields arranged on the side walls of the preheating cavities, through the cooperation of the protruding blocks on the drawer type containing boxes and the protruding blocks on the wind shields, the wind shields can be opened when the drawer type containing boxes are inserted into the preheating box bodies, and hot air is introduced; and when the drawer type containing boxes are pulled out, the wind shields return to the original positions, and the ventilation is closed, so that the excessive heating can be avoided, the energy consumption is lowered, and the energy is saved.

Description

technical field [0001] The invention relates to the field of preheating furnaces, in particular to a preheating furnace with uniform preheating. 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 preheating furnace with uniform preheating in order to overcome the above problems. [0004] In order to achieve the above object, the method adopte...
