Zinc sulfide drying device used for optical infrared imaging

Abstract

The invention discloses a zinc sulfide drying device used for optical infrared imaging. The zinc sulfide drying device comprises a box body, an electric heating device and drawers used for containing zinc sulfide. The box body is a cuboid box body and comprises a left side plate, a right side plate, a top plate, a bottom plate, a front door and a rear door. The electric heating device is arranged on the box body. The box body is partitioned into three heating areas in the front and back direction. The lengths of the areas in the heating areas are the same and are all larger than the length of the drawers. The heating temperatures of the areas in the three heating areas from front to back are lowered section by section. A plurality of beams are horizontally arranged between the left side plate and the right side plate. The box body is partitioned into a plurality of heating cavities through the beams from top to bottom. The drawers are installed in the heating cavities in a drawing mode and can move forwards and backwards in the heating cavities. The drying device can dry the zinc sulfide, and the drying effects of all pieces of zinc sulfide are basically kept the same.

Description

technical field [0001] The invention relates to a drying device, in particular to a zinc sulfide drying device for optical infrared imaging. Background technique [0002] At present, the market application of zinc sulfide continues to expand, especially in the field of infrared imaging. Infrared imaging technology has the advantages of long working distance, strong anti-interference, strong ability to penetrate smoke, dust, and haze, and can work all-weather and all-day. A wide range of applications, zinc sulfide as a basic material, has a wide range of needs in the field of infrared imaging technology. [0003] Zinc sulfide is made by the reaction of zinc sulfate and hydrogen sulfide. After the zinc sulfide is made, it needs to be washed with water, centrifugally dehydrated, and then dried. However, the drying of zinc sulfide is carried out in an ordinary oven at present, and the drying effect is poor. Moreover, the preparation of zinc sulfide is continuous, but the dryin...

Problems solved by technology

[0003] Zinc sulfide is made by the reaction of zinc sulfate and hydrogen sulfide. After it is made, zinc sulfide needs to be washed with water, centrifugally dehydrated, and then dried. However, the drying of zinc sulfide is carried out in an ordinary oven at present, and the drying effect is poor.

And zinc sulfide is prepared continuously, but the drying of zinc sulfide is not continuous, so the drying effect of each zinc sulfide is inconsistent
