Wicomsilo safety system
Wicomsilo Safety System
Filling a powders storage silo is always a critical operation because the air pressure can rise inside it at such a rate that it could put at risk the silo’s integrity.
WICOMSILO is a safety system which use a series of devices to prevent a dangerous build-up of internal pressure, such as would threaten the structure of the silo and the safety of anyone in the vicinity.
The WICOM Silo Safety System for the safeguarding of silos consists of a central electronic monitoring and control panel which manages a series of silos and a component kit including, in the basic version, one power panel for each silo, a silo pipe connection, a pinch valve, a tanker coupling to the filling pipe, a maximum level indicator, a differential pressure switch or electronic pressure meter, a pressure gauge for the venting filter, a pressure relief valve, and an audible alarm.
Functions
The WICOM Silo Safety System can be used for silos which are filled with powders or granular materials by tanker.
Damage to the silo or its accessories is most likely during filling operation from the tanker. This is due to the risk of overfilling or excess pressurisation.
The WICOM system, supplied in component form, prevents both overfilling and excess pressurisation, thus avoiding damage to the silo, to the venting filter or other accessories, and reducing the risk of dust emission into the atmosphere.
Options
- Central control panel
- Individual power panel
- Pressure gauge
- Pressure relief valve VDS
- Audible alarm
- Tanker coupling
- Venting filter
- Pressure switch/differential pressure meter
- Spigot for pressure switch/meter
- Level indicator
- Pinch valve incl. pneumatic control panel
The WICOM control box checks the air pressure into the silo and interacts with the several safety devices.
The MS pneumatic hose is located on the silo’s roof to connect WICOM control box to the inside of the silo.
The de-dusting filter unit MAXAIR-24, is designed to collect and release into the silo the powder rising during the silo’s filling. OPTIONAL.
The VDS/273 is a pressure relief valve safety device which automatically opens in case of the internal pressure exceeds the design rate.
The RLB level indicator, detects and displays via a lamp that the product has reached the maximum level in the silo.
The RLB level indicator, detects and displays via a lamp that the product has reached the maximum level in the silo.
The SA siren, is a safety device which gives an acoustic warning at any anomaly in the safety system.
VL pinch valve, designed to close the fill line in case of emergency. Available in two sizes: DN80 and DN100.
The PN pneumatic box contains the fittings to connect the pinch valve and the AIR pressure switch.
The E-100 adaptor ensures the connection between the tank lorry and the silo’s fill pipe via a STORZ coupling. Available in two sizes: DN80 and DN100.
The IT-100 adaptor ensures the connection between the tank lorry and the silo’s fill pipe via a PIN coupling. Available in two sizes: DN80 and DN100.
The CM terminal box collects all the cables coming from the devices and connects to the WICOM control box via ONE cable only.
