Scraper system for grit chamber
The scraper system is intended for installation in a horizontal grit chamber and removal of grit settled on the bottom with its subsequent transportation to the appropriate pit.
Ideal solution for existing grit chambers. Significant compaction of the sludge during the reciprocating movement of the scrapers.
The principle of operation of the scraper system based on the reciprocating movement of the scrapers, which have a special wedge-shaped hydrodynamic profile.
When moving “forward”, the end surfaces scraper profiles direct the settled grit towards the pit of grit tank. When moving “backward”, the sharp (sloping) profile of the scraper moves at almost double the speed, as a result of which the grit overflows through the sharp scraper part. As the result is an almost continuous transport of grit towards the pit. Due to the constant reciprocating movement of the profiles, the grit is compacted.
- Few moving parts.
- The minimum need for maintenance
- Continuous transport of the grit.
- No interference in the sedimentation process
- High operational reliability.
