Rotary air lock valve is also well-known as rotary feeders and is commonly used in agricultural as well as industrial applications as one of the important component in specialty or bulk material handling system. Their primary use included discharging bulk solid material from bins, receivers and hoppers into a vacuum-driven pneumatic conveying system.
Applications
Their common applications basically include gravity discharging/conveying and pneumatic conveying. Owing to these applications, they are commonly used with storage bins, baghouse hoppers and dust collection systems. The seal of this style of airlock valve is more suitable for low and moderately pressurized systems where small air leak is adequate.
Apart from this rotary air lock valve is also used in volumetric feed controls and dust control equipment. To describe more precisely, it has vanes that perfectly fit closely against the valve walls. When the vanes turn, it allows materials to pass through it without creating a direct opening between the outlet and inlet sides of valve. This airlock quality of rotary value contributes towards its usefulness.
Vanes present in rotary airlock valves are operated by making use of motor. The volume of material which can be moved in vanes can be measured by the vanes rotation. You can adjust the speed of the motor so as to increase/decrease the material flow rate in valves.
Following are some essential considerations for rotary airlock valves:
• The construction of the steel body, whether it is cast or plate steel
• Number of vanes in the airlock valves
• The size of opening in rotary valve
• Motor’s capability and size
• Type of material used to tip the vanes i.e. whether it is hardened or rubber steel
