a drying oven

Abstract

The invention discloses a drying box, and relates to the field of drying instruments. The drying box comprises a box body, a box door and an exhaust pipe communicating with the interior of the box body, and a first hollow cavity and a second hollow cavity communicating with the first hollow cavity are formed in the box body; and a heating sheet is arranged in the first hollow cavity, the side wallof the box body is provided with a blower fan which communicates with the second hollow cavity and is aligned with the first hollow cavity, exhaust holes are formed in the bottom wall and the side wall of the box body, the bottom wall of the box body is rotationally connected with a rotating shaft, a fan blade is arranged at the end, located in the first hollow cavity, of the rotating shaft, moreover, a supporting frame is arranged at the other end, located in the box body, of the rotating shaft, and trays are arranged on the supporting frame. The drying box has the following advantages and effects that the trays and materials are indirectly driven to rotate through the blower fan, meanwhile, the materials undergo air blowing drying in multiple directions, so that the heating surfaces ofthe materials in the drying box are more uniform, overheating damage caused by uneven heating of the materials is avoided, then drying quality and efficiency are improved, the waste of energy and resources is reduced, and the drying rate of the materials is improved.

Description

technical field [0001] The invention relates to the field of drying equipment, in particular to a drying box. Background technique [0002] The drying box is a device for drying wet items. According to the different dry substances, the drying box is divided into two categories: electric blast drying box and vacuum drying box. It has been widely used in chemical industry, electronic communication, plastic, cable, Automobile, rubber products and other industries. [0003] The Chinese patent with the authorized notification number CN103954104B discloses a drying box for drying electronic components and lithium batteries. There are heating sheets on the top and bottom respectively; the tray is used to contact the heating sheet through the lifting device to heat the products in the tray. [0004] When the above-mentioned drying oven is used to heat and dry the material, the heating surface of the material in the drying oven is always fixed, which makes the material heated uneve...

AI Technical Summary

Problems solved by technology

[0004] When the above-mentioned drying oven is used to heat and dry the material, the heating surface of the material in the drying oven is always fixed, which makes the material heated unevenly and easily causes overheating damage. This drying method cannot adapt to the needs of different drying characteristics of different materials. , not only affects the drying quality and efficiency, but also causes waste of energy and resources
