What industry is the wind knife applied to?

2021-09-21 12:00:00

Air knives have a large number of applications such as blowing water and blowing dust in the industrial field, such as blowing off dust and moisture on steel plates, aluminum alloy profiles, etc., blowing off water on the surface of beverage bottles, packaging cans, etc., and blowing off products Impurities and dust on the surface, residual liquid, moisture on the outer packaging, and cleaning of the conveyor belt. Under the condition of compressed air supply, the air knife can perfectly meet these applications. The air knife can be driven by a vortex fan or a high-pressure centrifugal fan (instead of compressed air with high energy consumption). It uses different fans to cooperate with the air knife to dry the dust and moisture on the surface of the object in time. According to different needs, air knives with different functions are extended. Working principle: After the compressed air enters the air knife, it is blown out at high speed with an airflow sheet with a thickness of only 0.05 mm. Through the Coanda effect principle and the special geometric shape of the air knife, the thin air curtain can accommodate 30-40 times the ambient air, forming a thin, high-strength, high-current impact air curtain.

F type cold wind knife

Air knives are divided into standard air knives and super air knives in terms of working mode. The air curtain of the standard air knives is deflected by 90 degrees and blows out, and the air curtain of the super air knives blows out horizontally. Features: The air knife is made of aluminum alloy or stainless steel. The aluminum alloy air knife is electroplated in the manufacturing process, and the service life is much longer than other similar products. The stainless steel air knife can be used in high temperature and high corrosion environments; the "full airflow" design, that is The width of the air knife is exactly the same as the width of the air curtain blown by the air knife. There are mounting and connecting screw holes on the back of the air knife, which can be combined according to the required length; the air knife can drain 40 times the ambient air, and the air consumption is only 1/5 of the traditional blowing pipe; the air knife has no wear parts inside, The gasket is made of stainless steel and has a service life of more than 10 years; it is driven by compressed air without electricity and can be used in an explosion-proof environment. The air knife produces a powerful air curtain, which can be used in various blowing and air cooling applications, such as: automotive industry: used to blow off extra water, coolant, dust, debris, etc. in manufacturing, and air cooling before painting the steel plate , Drying and dust removal. Electronics industry: The electronic circuit boards are quickly dried before assembly. F type cold wind knife

Beverage canning and bottle making: Blow off the water and attachments from the mouth or body of the beverage bottle before labeling, ink-jetting or packaging. Chemical industry: before labeling or packaging, blow off surface chemicals or moisture. Food and medicine: Blow off moisture and attachments before manufacturing or packaging, or remove dust from the opening and bag before bagging. Metal industry: blow off coolant or other liquids from the metal surface. The emulsion is blown off from the rolling mill. The surface is dried or cooled before polishing, electroplating, and painting. Rubber and plastic industry: blow off dust or debris on the product surface. Dry before extrusion or injection. The product is cooled after injection molding. Printing (Inkjet): Inkjet, blow off dust, debris, and water vapor before printing, or use the ink to dry quickly. Hot air knife
