The rotary feeder air knife is a kind of ventilation valve controlled by the solenoid valve, which is controlled by the pulse signal generator. The solenoid valve is used for pulse air supply according to the required opening and closing time, so that the powder materials from the pressure tank can be cut into the material plunger with the same length by the air knife. Pulse pneumatic conveying system is a promising pneumatic conveying mode due to its high productivity, material gas ratio M of 30~300, conveying distance of 500 m, low air consumption, low conveying wind speed of only 1~2 m/s, less pipeline wear, less broken materials during conveying, and low energy consumption.

旋轉(zhuǎn)供料器供料系統(tǒng)需要使用密閉性好的設(shè)備，不同工況設(shè)計(jì)不同的結(jié)構(gòu)及密封的選擇供料系統(tǒng)，供氣力輸送系統(tǒng)正壓的輸送使用，很好的解決了顆粒物料的防卡，粘附物料的粘壁，塑性物料的擠壓塑化，高溫物料的受熱膨脹，磨損物料的設(shè)備**，溫差物料的表面揭露等等一系列問題。

The feeding system of the rotary feeder needs to use equipment with good airtightness. Different structures and seals are designed for different working conditions. The positive pressure transmission of the pneumatic conveying system solves a series of problems, such as the anti seize of granular materials, the sticking of materials to the wall, the extrusion and plasticization of plastic materials, the thermal expansion of high-temperature materials, the equipment * * for wearing materials, and the surface exposure of temperature difference materials.
