Development of automobile spraying soot blowing air knife application in future industrial field

After the compressed air enters the air knife, it is blown out at high speed with a thin airflow sheet with a thickness of only 0.05 mm. Through the Coanda effect principle and the special geometric shape of the air knife, this sheet air curtain can reach 30 to 40 times the ambient air at most, forming a thin high-strength, high-flow impact air curtain.

Features of car spraying dust blowing air knife:

1.Stainless steel 304 is used as the body of the blade, and aluminum alloy is used as the blade. The production is precise, the air is strong, and it has the characteristics of energy saving, high efficiency, practicality and reliability.

2.The unique structural design ensures small wind resistance, uniform wind speed, and the accuracy can reach ±5%.

3.The width of the air outlet of the air knife can be adjusted to 0.1mm (the precision can reach 0.1mm). The blade size can be customized according to customer requirements, and the length can reach 6m.

4.A variety of air inlet calibers and positions are optional, and the screw-shaped or pagoda-shaped air inlet can be selected to meet the requirements of screw connection or hose connection and facilitate installation.

5.It can withstand high wind speed of 200m/s, high temperature resistance of 250℃, and maximum pressure resistance of 2kgf/cm2.

6.It can be used with vortex fans and centrifugal fans, and the application is flexible and convenient.

7.The air knife is matched with the hot air blower, which can perform hot air drying and hot air rapid drying, avoiding the use of ovens and other drying methods that require large investment and energy.

8.Air knife products are packed in wooden boxes, with one-year after-sales service and lifetime maintenance.

9.The air knife is made of aluminum alloy or stainless steel. The aluminum alloy air knife has been electroplated in the manufacturing process, and its service life is much longer than other similar products. The stainless steel air knife can be used in high temperature and high corrosion environments.

10."Full airflow" design, that is, the width of the air knife is the same as the width* of the air curtain blown out by the air knife. There are installation and connection screw holes on the back of the air knife, and the required length can be combined as required.

11.The air knife can drain 40 times the ambient air, and the air consumption is only 1/5 of the traditional blowing pipe.

12.There are no wearing parts inside the air knife, and the internal gasket is made of stainless steel, with a service life of more than 10 years.
