Strainer/Mixer with Scraper
(Patent No. 7,981,282)
The Model 763 Automatic Slurry Strainer/Mixer with Scraper provides removal of solids and debris without flow interruption. The strainer is designed for applications that have heavy solids loading with particles ranging from 75 micron to 12mm (0.003" to 1/2" diameter particle).
The inlet and outlet is inline to fit most piping arrangements. The inlet area is designed as a first stage separator, allowing particles that have a heavy density to settle out before reaching the screen. The retention drain has a large holding capacity. This drain is not located in the normal flow area so that it does not experience any agitation or fluid velocity. The unit is designed for continuous cleaning cycle or a timed cleaning cycle. The valve on the blow off connection can be timed, cycled for cleaning, or manually operated.
This unit has rails to aide in the removal of the screen and in the adjustment of the scraper blade. When adjusting the scraper blade, the screen can be manually turned for fine adjustment. The screen and scraper blade is a one piece sub-assembly. All screens are fabricated and machined for a tight tolerance and true running surface. The blade can be manufactured from various metals and plastics.
