Air Knocker

Air Knocker is a pneumatic device used in industrial settings to solve flow issues in silos, hoppers, and pipelines. It functions by delivering a precise, high-impact mechanical shock to the exterior of a vessel to dislodge material that has bridged, rat-holed, or stuck to the walls.

Feature of Air Knocker:
- Higher impact force at lower pressure and less kinetic energy’s loss due to light body made from magnesium alloy.
- Tubing range up to 20 m without auxiliary equipment is benefit from special development of floating valve seat.
- Impact force is adjustable by setting air pressures.
- Multiple knockers can be controlled by 1 control box.


Why Choose an Air Knocker.
- Preventing Damage: Because the device delivers high-energy impacts, it is crucial to mount it on a reinforced mounting plate to prevent the vessel wall from cracking or denting over time.
- Adjustability: The force of the impact can often be controlled by adjusting the air pressure, allowing you to fine-tune the force to match the vessel's structural integrity and the material's properties.
- Applications: They are widely used in chemical plants, food processing (to avoid dust buildup), and cement or mining industries where materials are prone to bridging.



Internal Structure and Principle:
- Charging: The Compressed Air flows along the Valve Chamber and enters the Air Chamber.
- Trigger: According to the setting on the Timer Setting, the Diverter Valve (three-way valve) is opened, influencing the differential pressure (Delta P) and triggering the Valve Seat to operate. Subsequently, the compressed air is ejected into the Piston Chamber in a moment.
- Impact: The compressed air pushes the Piston down rapidly, causing an impact and vibration on the Mounting Base to dislodge the clogged material.
