Description

Technical Field

[0001] The utility model relates to the technical field of drying box nozzles, in particular to a single air outlet nozzle and an assembly structure thereof. Background Art

[0002] Drying is the process of removing water or other solvents from materials. Most drying ovens use nozzles to spray hot air to evaporate the water in the material.

[0003] The uniformity of the drying process depends on the distribution of hot air. If the air is unevenly distributed, it will cause local overheating or insufficient drying, which will affect product quality. Therefore, improving the uniformity of air flow is the key to improving the drying efficiency and product quality of the drying box. In order to achieve better drying effects, scientific design of air flow is required. This includes nozzle design, air duct design, and internal structure design of the box, etc.

[0004] The utility model with the publication number CN203586711U proposes a flotation drying box nozzle, including a fixed bottom plate, left and right wall panels are arranged on the fixed bottom plate, middle orifice plates are arranged in the left and right wall panels, and guide plates are arranged on the middle orifice plates in the left and right wall panels. The fixed bottom plate, the left and right wall panels and the middle orifice plate form a lower chamber, and the space surrounded by the middle orifice plate and the guide plate is an upper chamber. However, the nozzle still has two air outlets, which results in air outlet on both sides when paper is dried through the nozzle. In this way, one side of the nozzles arranged on both sides of the drying box sprays hot air outward, and the hot air sprayed outward directly causes the loss of hot air flow. The lost hot air flow not only leads to a waste of energy, but also may cause overheating and damage to surrounding electronic and mechanical equipment.
