Rotary drying furnace

Abstract

The invention discloses a rotary drying furnace, which comprises a furnace body, a rotary heating frame rotatably arranged inside the furnace body, and an air heating circulation device, wherein the rotary heating frame comprises round supporting plates respectively arranged at the upper end and the lower end of a rotary shaft, and at least three rectangular hanging boards which are parallel to the rotary shaft and symmetrically fixed between the two supporting plates at intervals; hanger structures are arranged on the inner sides and the outer sides of the rectangular hanging boards; a rectangular opening is arranged at the front part of a heating cavity of the furnace body; and the rotary heating frame is eccentrically arranged in the heating cavity, wherein a portion of the rotary heating frame is exposed outside a box body through the opening, so that dry components can be hung and taken down. The rotary drying furnace adopts external heating, and improves the utilization efficiency of the internal space; the traveling traces of all the components during the heating process are the same; and even small differences exist in partial temperatures, the heating effect under different temperatures can be balanced efficiently for the reason that the heating time of each component at different locations are the same.

Description

technical field [0001] The invention relates to a drying oven, in particular to a drying oven which can be used for drying the interior parts of automobiles. Background technique [0002] Automobile interior parts, such as the O / M skin in the door panel, need to be dried after the adhesive is applied. The commonly used parts drying oven is a drawer-type multi-compartment drying oven. The heater is installed inside the furnace to heat the product and the air in the furnace. The time management of the drawers, and in order to promote the flow of hot air in the box, a fan is also arranged on the rear side of the inside to make the hot air enter each heating drawer. [0003] However, the existing drawer-type structure occupies a large space in the box, resulting in poor air circulation in the box, and the heater cannot dissipate heat evenly, which causes local overheating or low temperature. Although a fan is used for hot air circulation, but because each heating The air press...

Problems solved by technology

[0003] However, the existing drawer-type structure occupies a large space in the box, resulting in poor air circulation in the box, and the heater cannot dissipate heat evenly, which causes local overheating or low temperature. Although a fan is used for hot air circulation, but because each heating The air pressure at the drawer is different, so that the temperature of each heating grid is different, and the product quality is not uniform, which affects the product quality; and the drying furnace is made into a honeycomb drawer type, and the time management of each grid increases the burden on the system. Inconvenience, such as a drawer time management failure, this warming drawer can not be used, will affect the production efficiency
