Homogeneity blast heating vacuum drying box

Abstract

The invention discloses a homogeneity blast heating vacuum drying box. The homogeneity blast heating vacuum drying box comprises a heating box body and a box door, the side, facing the box door, of the heating box body is of an open structure, and the heating box body and the box door are closed to form a heating cavity; one set of heating pipe is embedded in the parts, facing the heating cavity,of the top and bottom of the heating box body respectively, one set of blasting panel is mounted on the parts, facing the heating cavity, of the left side wall and the right side wall of the heating box body respectively, and the two sets of blasting panels are connected with a same air blower through air inlet pipelines; and the sides, facing the heating cavity, of the blasting panels are evenlyprovided with ventholes. On the one hand, the homogeneity blast heating vacuum drying box make the heating temperature at each position of the heating cavity from bottom to top be the same, on the other hand, the intensity of the drying air applied to to-be-dried objects on different grids in the heating cavity is the same; the internal heating temperature is homogenous and stable, the intensity of the drying air on the same grid is the same, the whole drying homogeneity of the drying box is effectively improved, and the drying quality is improved.

Description

technical field [0001] The invention relates to the field of drying ovens, in particular to a uniform blast heating vacuum drying oven. Background technique [0002] Electric blast vacuum drying oven is a kind of equipment that uses electric heating for blast drying. It is mainly used in chemical industry, electronics, foundry, automobile, food, machinery, biotechnology and other industries. Existing electric blast drying ovens generally include: a drying oven, the interior of which has a drying chamber, an air blast assembly, a heating pipe, a vacuum device, and the like. [0003] The design of the heating device and blowing device in the existing drying box is unreasonable. The uniformity of heating and blowing at different positions inside the drying chamber are not the same, and the degrees of heating and drying of items at different positions are different, which affects the drying of items. The performance, especially for chemical, food waiting for drying performance ...

Problems solved by technology

[0003] The design of the heating device and blowing device in the existing drying box is unreasonable. The heating uniformity and blasting uniformity at different positions inside the drying chamber are not the same, and the degree of heating and drying of items at different positions is different, which affects the drying of items. The performance, especially for chemical, food waiting for drying performance is greater
