Description

Technical Field

[0001] The utility model relates to the technical field of paper production and drying equipment, in particular to a moisture drying device for paper production. Background Art

[0002] Paper: a thin sheet made of plant fiber, used for writing and painting, printing books and newspapers, packaging, etc. Paper: a general term for paper. Paper is measured in sheets, hence the name.

[0003] In the process of paper production, some high-end papers and papers for special purposes need to be dried separately. Traditional box-type drying equipment mostly uses a heater to blow air at a fixed point for drying. Although this method has a low cost, the temperature at a certain point in the drying process is higher than the temperature at other positions, which causes drying wrinkles and uneven temperature radiation, and it is easy for water vapor to accumulate on the top of the device, which easily soaks the paper again. If microwave drying is used, the drying will be uniform, but the production cost is high, resulting in increased production cost. Based on this, a moisture drying device for paper production is proposed. Utility Model Content

The air flow enters and is discharged from the partition 8 through the guide air holes 10, so that the air flow carries water vapor to contact the metal hollow mesh 12 and the zeolite 13, so as to absorb and condense the water vapor. When the zeolite 13 absorbs a large amount of water vapor, water is introduced through the water inlet pipe 5, the connecting pipe 3 and the hollow guide pipe 14 for condensation, so as to facilitate discharge.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
