Improved structure of air hose of drying furnace

Abstract

The invention discloses an improved structure of an air hose of a drying furnace, which comprises a vertical pipe and is characterized by further comprising an arc-shaped bend, wherein the arc-shaped bend communicated with the vertical pipe is arranged on the lateral surface of the bottom of the vertical pipe in connection mode, and the vertical pipe and the arc-shaped bend are made of aluminum alloy materials. The improved structure solves the problems that oil dirt can be accumulated on an air hose of a drying furnace in the prior art, the oil dirt can slide into the drying furnace under effect of gravity and fall on the surfaces of products, product quality can be affected, and the appearance of the products can be unattractive. The improved structure is simple in structure, convenient to use and capable of guiding flow for the oil dirt and avoids the oil dirt from falling on the surfaces of the products. The arc-shaped bend communicated with the vertical pipe is arranged on the lateral surface of the bottom of the vertical pipe in connection mode, and the oil dirt is guided by the arc-shaped bend in falling and cannot fall on the surfaces of products, so that surface appearance of the products is ensured, reject rate is reduced, and the improved structure has good economic benefit.

Description

technical field [0001] The invention relates to the technical field of air ducts, in particular to an improved structure of an air duct of a drying furnace. Background technique [0002] After the mobile phone button product is painted, it needs to be placed in a drying oven for drying treatment. During the drying process, the air duct on the drying oven will accumulate oil. Since the current air duct adopts a straight-up and straight-down type, when the oil volume is large, Under the action of gravity, the oil will slide down into the drying furnace and fall to the surface of the product, which will affect the quality of the product and cause the appearance of the product surface to be poor. Contents of the invention [0003] In order to solve the problem that the air duct on the drying furnace in the prior art will accumulate oil stains, and under the action of gravity, the oil stains will slide down into the drying furnace and fall to the surface of the product, affecti...
