Air knocker RKV series (Indirect impact type)

Eliminate the blockage of powder by automation of hammering!

This product is used for the following applications:
1.Prevention of clogging in hopper in sewage sludge fuel production facilities
2.Prevention of blockage in dust hopper for dust collector in waste treatment plant
3.Prevention of blockage in the recycle fuel (capsule of compressed wood) supply hopper
4.Prevention of blockage in the glass cullet storage hopper
5.Elimination of clogging of livestock forage silo
6.Facilitation of ejection of silica gel
7.Elimination of adhesion of calcination product raw material on wall surface
8.Knocking off the ash in the recycling plant. Facilitation of ejection of aluminum powder
9.Prevention of adhesion in piping in pharmaceutical plant

Features
The Air knocker (Indirect impact type) is a unique equipment in which the force of compressed air causes the piston to energetically strike the base surface, which eliminates the adhesion or clogging of powder. In addition, this knocker is excellent in safety and economics because it can be used only by air supply, and it can be used safely for powder that has a characteristic to show adhesion when receiving the centrifugal vibration.

Adjustable impact force
In the air knocker series, just changing the pressure of supply air allows the impact force to be changed by the special mushroom valve (patented). The air pressure is increased if the blockage cannot be eliminated, and is decreased if the impact force is too strong. Moreover, the adjustment of pressure is effective in reducing noise. Even if wrong selection of model results in excessive or poor capability during installation work, such a problem may be solved by adjusting the impact force. Thus, the adjustable impact force mechanism is appreciated in the field.

Relay piping allowing multiple units to be used simultaneously
Air knocker is equipped with relay piping function (patented) in which one control panel can operate more than one unit simultaneously. In the similar way, one controller or the control panel dedicated to knocker can use more than one unit. Thus, the introduction of relay piping will decrease the facility cost because the number of control panels in overall facilities can be reduced.

Operating principle of Air knocker
1.The compressed air flowed into the knocker is first supplied to the valve chamber to depress the mushroom valve and then is stored in the accumulator.
2.When the three-way valve is actuated to exhaust the air from the valve chamber, the compressed air in the accumulator moves the mushroom valve upward.
3. When the mushroom valve moves, the compressed air in the accumulator depresses the piston energetically, which strikes the base surface. That impact force eliminates the adhesion or blockage of powder.

Oil-free and environmentally friendly
The air knocker series require no lubricant during operation. It is suitable for the work environment in factory because it does not produce oil-mist. Oiler is not needed to be installed in the air supply facilities, which brings great advantages on customers, such as cost reduction and no lubrication maintenance required.

Simple structure and high durability
The air knocker series withstand a million times of hammering. They have durability supported by high design basis and have a simple structure, which provides almost maintenance-free performance and requires no additional spare parts. In long-term delivery record of this air knocker series, customers have appreciated its maintenance-free performance with almost no failure.

Adoption of convenient push one joint (only for RKV20)
The product adopts directionally-adjustable and removable push one joint. Tubes to be mounted to the joint are changed from the conventional 8mm type to the 6mm type.
*The kit in which the 6mm tube can be used for the controller with a discharge opening diameter of 8mm are attached as standard equipment.

Various types of dedicated controllers for knockers are available
The dedicated control panel is available for operation of air knocker series and stainless steel knocker series. The control panels include the air operation controller AOC-1B type that can start operation readily without electric power, the timer control panel for solenoid valve control KSE1 type that controls the interval between impacts and the number of impacts, and the control panel HKE series, or the control panel EKE5000 with free input voltage specification from 100 to 240VAC. In addition, the fully air controlled control panel HKA5000A for explosion-proof area is available. (Option)
