Opicon’s control system for the process of separating slurry and sand and the retention and cleaning of sand for reuse is built up in a way to grant fully automatic, continuous operation..
The process, as described in the section ”solutions”, among other things, is controlled by strategically placed measuring devices for flow and dry matter content. The information from these devices is registered in a PLC. Based on this information, the PLC is programmed to control the operation of the mixer in the raw slurry tank, the pumps and valves to achieve the required flow and dry matter content, flow and pressure of cleaning water to the sandbed, the function of the sandwasher’s agitator and auger, etc.
All the data is logged making it possible to continuously follow the performance history.
The different parameters can be adjusted via touch screen or via remote control from a PC or smart phone.
