The basic function and characteristics of wind knife

There are a large number of applications for air blowing and dust removal in the industrial field, such as removing dust and water from steel plates, aluminum alloy profiles and other flat surfaces, removing water from the surface of bottles such as beverage bottles and packaging cans, removing impurities on the surface of products, dust, residual liquids, water on the packaging, and cleaning conveyor belts. With a compressed air supply, the air knife is perfectly suited for these applications.

The air knife is can be driven by vortex fan or high pressure centrifugal fan (instead of high energy consumption of compressed air), it uses different fans with the air knife, can be in a timely manner to the surface of the object of the dust debris and moisture blowing dry.

HBO wind knife / waterjet series of products, especially suitable for circuit boards, plating parts, coating, ultrasonic cleaning, coating, non-ferrous metal plate / wire production, glass production and other different industries in a variety of processes in the de-watering and drying; can be used for hazardous gases, dust, hot and cold air barrier-free isolation, printing to the paper blowing and printing on the paper and post-drying; can be used for food, medicine and rapid heating, defrosting and sterilization at high temperatures.

HBO wind knife all use stainless steel 304 material, food or Medicine and other special environment using 316 health-grade stainless steel, high corrosion and rust resistance. The wind knife is made of precision, strong wind, even wind curtain, high temperature resistance, energy saving, high efficiency, practical and reliable features.

HBO Air Knife Characteristics:

1、Outlet width adjustable (0.1-5mm), customized length up to 6 meters.

2、Multiple connection methods for air intake, with adjustable angles to ensure the best results.

3、A variety of specifications to choose from, suitable for different industries with different application needs.

4、The knife body temperature resistance of 350 degrees, pressure resistance of 5KG/cm, special needs can be further enhanced.

5、The structure is uniquely designed to ensure that the wind resistance is small, the wind speed is average, and the wind shape is uniform.

6、Air compressor, vortex fan, centrifugal fan can be used as air source, flexible and convenient application.

7、Matching with hot air blower, it can carry out hot air dryer and hot air rapid drying or sterilization.

8、Small air knives can be discharged side by side or used individually, especially for special process needs.

Customized forms are available for different needs:

1、Can be customized all kinds of types of shaped structure of the wind knife, to meet the special purposes.

2、Customizable hot air shrinkage air knife with heating structure, especially useful for large objects packaging.

Suggestion for using Hunan HBO Air Knife:

1、Rapid dewatering: wind speed 70 ~ 120m/s, air outlet width of 1 ~ 1.5 mm.

2、General dewatering: wind speed 50 ~ 80 m/s, air outlet width 1 ~ 1.5 mm.

3、Water-based coating drying: wind speed 40m/s, air outlet width 5mm.

4、Rapid drying: wind speed 60-80m/s, air outlet width 2-5mm, temperature 150 ° C-250 ° C.

5、Hot air drying: wind speed 20-60m/s, air outlet width 2-5mm, temperature 60 ° C-150 ° C.

6、Instant sterilization: wind speed 70-150m/s, air outlet width 0.25m, temperature 300°C.

7、When the wind knife is too long, in order to ensure the uniformity of the air outlet, it is necessary to increase the number of air inlets and air volume distribution box.

Application of HBO Air Knife：

The wind knife produces a powerful wind curtain, which can be used for various blowing and air-cooling applications.

1、Automotive industry: used for blowing off extra water, coolant, dust, debris, etc. in manufacturing, as well as blowing cooling, drying and dust removal before steel plate painting.

2、Electronics industry: rapid drying of electronic circuit boards before assembly.

3、Beverage Filling and Bottle Making: Blow off moisture and adhesion from bottle tops or bottles before labeling, inkjet or packaging.

4、Chemical industry: blowing off surface chemicals or moisture before labeling or packaging.

5、Food & Pharmaceuticals: Blowing out moisture and adherents prior to manufacturing or packaging, or opening and de-dusting bags prior to bagging.

6、Metal Industry: Blowing off coolants or other liquids from metal surfaces. Blowing off emulsions from rolling mills. Surface drying or cooling before polishing, plating, painting and coating processes.

7、Rubber & Plastic Industry: Blowing off dust or debris from the product surface. Drying before extrusion or injection. Cooling of products after injection molding.

8、Printing: Inkjet, pre-printing dust, debris, vapor blowing, or for rapid ink drying.
