Dust-free and environmentally friendly film drying device

Abstract

A dust-free and environment-friendly film drying device relates to the field of film drying. The present invention solves the problem that the existing method of drying the film has low drying efficiency; the air is polluted to a certain degree, and the dust in the air easily falls on the surface of the film to contaminate the film. Dust-free and environmentally friendly film drying device, including drying box and waste discharge box; the side of the drying box is set as a condensation plate, the bottom is set as a deflector, and the other side is set with multiple fans; outside the fan There is also an air filter plate; a guide roller and a heating pipe are fixed in the drying box; a waste gas discharge port is provided in the waste discharge box; a waste water discharge port is provided at the bottom of the waste discharge box. The invention adopts a semi-closed design, so that during the drying process of the film, the water vapor can be discharged in time, and the harmful gas can be treated for waste gas, ensuring the dust-free state during drying; moreover, the film is bent in a W shape Transportation greatly increases the space utilization of the drying device, making the film drying process more efficient, energy-saving and environmentally friendly.

Description

technical field [0001] The invention relates to the field of film drying, in particular to a dust-free and environment-friendly film drying device. Background technique [0002] The existing methods of drying the film generally adopt closed drying or open drying. When using closed drying, a large amount of water vapor generated during drying will cause the humidity in the drying room to increase due to the airtightness. The higher the drying rate is, the drying efficiency will be greatly reduced; when using open drying, the volatile harmful gas of the membrane itself will continue to diffuse into the air during the drying process, causing a certain degree of pollution to the air and harming the air. Moreover, the dust in the air is very easy to fall on the surface of the membrane during drying, causing secondary pollution of the membrane and reducing the quality of the membrane. Contents of the invention [0003] In order to solve the above technical problems, the present...
