Portable air cooling film drying apparatus

Abstract

The present invention discloses a portable air cooling film drying apparatus. The drying apparatus comprises: a drying oven housing, wherein both the upper and lower ends of the drying oven housing are of an open shape; a bracket structure for placing a film cartridge is arranged in the drying oven housing; at least one air blowing apparatus and at least one air suction apparatus are arranged on the drying oven housing; a drying oven cover, which is detachably mounted on an upper opening of the drying oven housing; and a wastewater containing apparatus, which is detachably mounted on a lower opening of the drying oven housing. The film cartridge filled with films is put on the bracket structure inside the drying oven housing; and the air blowing apparatus is used for blowing the outside air into the drying oven housing, and the air suction apparatus is used for sucking out the air inside the drying oven housing. The portable air cooling film drying apparatus provided by the present invention is convenient to use, simple in operation method, and easy to carry, so that working efficiency is improved, a rejection rate of the films is reduced, and the portable air cooling film drying apparatus has a certain environment protection function.

Description

technical field [0001] The invention relates to the technical field of film drying, in particular to a portable air-cooled film drying device. Background technique [0002] In the drying process of ordinary film drying ovens, the common method is to put the film processed in the darkroom into the ordinary drying oven, and the drying is usually completed in 15-20 minutes. However, once the operator neglects the time, the film will be over-dried. It will affect the quality of the film; at the same time, when the film is processed in the darkroom, it usually goes through three steps: film development, film fixing, and film washing. Benzene, methanol, silver halide and other boric acid, hydroquinone bleach and fixer contain harmful components such as bromide developers CD2, CD3 and CD4. The silver ion contained in the fixer is a powerful bactericide, and too much silver in the wastewater will affect the biological treatment effect of the wastewater treatment plant. After devel...

[0002] In the drying process of ordinary film drying oven, the common method is to put the film processed in the darkroom into the ordinary drying oven, and the drying is usually completed in 15-20 minutes. However, once the operator neglects the time, the film will be over-dried. It will affect the quality of the film; at the same time, when the film is processed in the darkroom, it usually goes through three steps: film development, film fixing, and film washing. Benzene, methanol, silver halide and other boric acid, hydroquinone bleach and fixer contain harmful components such as bromide developers CD2, CD3 and CD4

The silver ion contained in the fixer is a powerful bactericide, too much silver in the wastewater will affect the biological treatment effect of the wastewater treatment plant

After developing, fixing and washing the ordinary film holder, take it out into the drying box, part of the liquid will flow to the ground, and part will be dried in the drying box, the outflow of developer and fixer will not only affect There is pollution in the outside world, and more importantly, the loss of Ag ions in the fixer solution will cause certain losses to the enterprise and society.

Therefore, the traditional film drying oven has great limitations on the work of drying film
