Air-flow type drying oven for drying coating layer of radiate material and blast nozzle parts thereof

Abstract

The invention discloses an air flow drying oven for drying the coating of a radiate material and a blast nozzle part thereof. The blast nozzle part is a case, the lower part of which is provided with an air inlet. The middle of the upper part of the case is provided with a guide roller groove, and the case is provided with an inner cavity at the lower part and a left air duct and a right air duct which are positioned at the left side and the right side of the upper part and directly communicated with the inner cavity. An air outlet of the left air duct is a left parallel air flow blast nozzle which inclines towards the left, and the air outlet of the right air duct is a right parallel air flow blast nozzle which inclines towards the right. When the blast nozzle part is used in the drying oven, the left and right blast nozzles accelerate the flow flowing to the left and right sides of the blast nozzle part, and a left horizontal supporting plate and a right horizontal supporting plate lead the air flow to form parallel wind which is parallel to the radiate material, thus increasing the direct contact area between the wind and the radiate material, leading the radiate material surface to be heated evenly and the heat exchange between the parallel hot wind and the radiate material to be more sufficient, improving the heat exchange efficiency and having better drying quality due to even heating.

Description

technical field

[0001] The invention relates to a drying device, in particular to a drying box for drying a liquid coating coated on one side surface of a web-like material and an air nozzle part thereof. Background technique

[0002] Radial materials refer to thinner banner-shaped paper, plastic film, non-woven fabrics, etc. In order to increase the functions of these radial materials, it is often necessary to coat one side of these web-shaped materials with a liquid coating with certain functions. Layers, such as adhesives, anti-adhesive silicone oil or protective coatings, are then dried by a drying process to fix the liquid coating on the radial material. The drying of the liquid coating on the radial material is usually carried out in a drying tunnel or drying oven provided with a radial material inlet and outlet and a radial material conveying device. The box body of the drying box is generally made of thermal insulation materials; some drying boxes are also equipped ...
