Gericke’s range of pre-engineered packaged vacuum conveying solutions have been designed to assist in loading and refilling processes, driven by venturi ejector. By using an electric pump, on short distances, a dense phase conveying mode can be approached.
The modular design provides the opportunity to adapt the suction device to various different handling or process equipment. Sack tipping, Drum unloading, BBU Big Bag Unloading, feeder refilling, reactor loading, to name some examples. Vacuum conveyors are compact and light and are suitable for manual or automated operation.
Most of Gericke’s package vacuum conveying systems work on what is referred to as a "suck and dump" system. This is a cyclic operation where the system conveys for a set time or to a level, conveying stops, the discharge valves opens and the filters are cleaned. This sequence is then repeated.
There are a three crucial elements required for any package vacuum system, these are:
1. The material pick-up point. This can be a variety of different equipment dependant upon the type of material being handled, some of which are:
2. The vacuum receiver. This piece of equipment is positioned at the end of the conveying line and is used to separate the product from the laden conveying air. As the product enters the receiver it reduces in velocity and drops out of suspension to the bottom of receiver. The vacuum source pulls the dusty conveying air to the top of the receiver, where a filter assembly is positioned, ensuring the air leaving the receiver is clean. In addition the filters are automatically cleaned on every discharge cycle via a compressed air blast.
3. The vacuum generator. This can either be an electrically powered vacuum pump or a vacuum ejector operated with pressurized air.
Pumps or ejectors are selected on an application dependant basis, taking into consideration all of the conveying requirements.
