Principles and Features
Compressed air is introduced to the air tank of the Knocker and the piston momentarily works by opening/closing the inside valve using three-way valve. The generated impact will avoid the powder sticking/clogging problem at hoppers. This system eliminates the manual hammering work. Fully automatic operation is possible. Hammering strength is adjustable by changing pressure. Multiple knockers can be installed by single valve action.
Tubing for Multiple Air Knocker installation
When multiple installation, compressed air is supplied through three-way valve to tank-center port of the knocker. And from the next sub port, another tube is connected to the next air knocker main port. And the 3rd and more knocker can be connected in the same way. All the air knockers work almost at the same time (very short time lag). Multiple air knocker can be operated by single valve action, which decreases the initial cost. Maximum quantity (3 to 10 units) depends on the control and the three-way valve. (Patented)
Installation Method
- When wall thickness in the installation part is thin, prepare the reinforcing plate of 3 2 to 6 mm thick, and weld the center and around the whole reinforcing plate in front fillet welding to the hopper for transmitting percussion force more efficiently.
- Weld around the whole circumference of the base.
- For the model larger than RKV60, weld accessory reinforcing rib usually necessary for RKV30P and 40P.
- Tighten the body thoroughly, using accessory bolt, spring washer, and hard lock nut.
- Secure the knocker by suspending with wire rope to prevent the knocker from dropping.
