Drying-box door

Abstract

The invention relates to a drying-box door, which comprises a door frame and a rolling track, wherein the door frame is arranged in a box-body opening, the rolling track is installed on the door frame, a box door is fixedly arranged on the rolling track through a pulley, a lifting iron chain is installed at the upper end of the box door and is connected with a minor crane, the minor crane is installed at the upper part of the box body, heat-preserving cotton beyond the edge of the box body is arranged on the inner wall of the box body, compacting devices are installed on the box body at the periphery of the box door, and lugs are positioned at positions where the framework of the box door and the compacting devices are buckled, and are positioned on the box door. Differing from a traditional drying-box door, an up-down stretching-type structure and the compacting device are adopted by the drying-box door disclosed by the invention; compared with a traditional door opening-closing type drying-box door, better sealing and heat-preserving effects are achieved. The heat-preserving cotton is adopted on a sealing surface, so that the sealing effect can not be influenced due to stretching for many times. Since the structure that the box door is stretched through the crane is adopted, manpower is saved, so that the design is applicable to large and small drying boxes.

Description

technical field [0001] The invention relates to the field of oven manufacture, in particular to the design and manufacture of an oven door. Background technique [0002] With the advancement of human science and technology, ovens have been widely used in the field of science and technology. In general applications, the oven plays the role of drying, which requires the oven to have a better heat preservation and sealing effect. In the drying of some chemicals, the oven sometimes needs to achieve a vacuum effect, which requires further strengthening of the sealing effect of the oven. However, the traditional oven door generally adopts an open door oven, and a sealing strip is used to seal the box body and the box door. However, after many times of opening and closing, the sealing strip will gradually lose its original sealing performance, and the sealing effect will change. Difference. [0003] Therefore, the above-mentioned problems should be considered and solved during t...
