The Solution
AGRICHEMA’s SHOCK-BLOWER® air-blast units store highly compressed air (or inert gases) up to 10 bar which can be expelled, if necessary, within milliseconds in an explosion-like manner.
By injecting the explosion-like air-blasts through specific expansion guide nozzles precisely focused into the separation layer between the wall and the bulk
material, the latter is literally “peeled” from the wall and moved towards the outlet.
The Concept
SHOCK-BLOWER® air-blast units are applied in “critical” zones where caking of material and bridge formation may occur.
By expelling air-blasts, if necessary, in a time-programmed sequence, active flow zones are created, causing even highly cohesive bulk material to flow.
The Design
Execution Valve units DN 100 and DN 150.SHOCK-BLOWER® from AGRICHEMA consist of a storage tank for compressed air or inert gases and a valve unit with control unit.
The storage tanks are made according to EURO standards and are hot galvanised on the inside and outside.
The valve unit with its vent seat made of Cr-Ni-steel is protected and arranged within the storage tank, even so it can be easily maintained and controlled from the outside.
The control unit “SIKOBETIC®” from AGRICHEMA guarantees a reliable operation of air blast units (even during fluctuations in the compressed air network). Additionally the “SIKOBETIC®” offers a simple handling and maximum security for the operating staff.
Execution Valve unit DN 40 and DN 65
The air blast forces have been tested at the Chair of Mechanical Process Engineering of the University of Kaiserslautern with state-of-the-art methods. The corresponding study can be obtained as special print from AGRICHEMA (English version).
Accessories
SIWARTIC®
AGRICHEMA's SIWARTIC® with filter regulator and 3/2-way ball valve, lockable threefold, is used as safety maintenance unit for reliable compusulsary venting of SHOCK-BLOWER® units.
Automatic Cycle Control (ATS) The automatic cycle control for SHOCK-BLOWER® (ATS) is freely programmable.
Thus, all bulk material disruptions can be eliminated by individual control of the SHOCK-BLOWER® units.
The SHOCK Control (SCS) is monitoring the SHOCK-BLOWER®'s function.
Option: Pressure sensor/pressure transmitter for monitoring the operating air pressure.
Further Accessories:
Air pipes, sets of fittings and installation accessories.
