Coarse Screen
WateRRake Model CS1 is designed and built for removal of large suspended solids. The mechanism is rugged and easy to operate. Grab carriage can run to the lowest position to sweeps up the trash which settled on the floor, thus the cleaning is so efficient. The cleaning is made possible by grab controlling through 3-cable motion. Two cables are used for lifting and lowering of grab, while the other is for opening and closing of grab. On downward position the grab runs in open position until reaching the floor or obstruction, where the slack line sensor sends a signal to close the grab, through turning the swiveling rollers whereby the length of the center cable is changed and close the grab. Then the lifting motor runs into reverse motion lifting the grab upward for discharge above floor. In automatic operation the cleaning sequence is repeated continuously until all suspended solids are removed.
Cleaning at any Depth
Model CS1 employs the slack line balancer that will activate and start several cleaning motions at different depth until the surface is cleared off all floatable. The same kind of action is repeated for heavy deposits on channel floor until the bar screen get thoroughly cleaned.
Rake Teeth Penetration
The toothed rake can be adjusted to regulate the penetration of the toothed tips between the screen bars. This finer adjustment permits Model CS1 to rake all finer trashes, which plugged between bar screen.
Fully Automated
The drive can be set to time or level difference function to start and stop automatically. The control is so designed that warnings such as `rake does not reach channel floor`, `cable rupture` or `electrical failure` can be shown when screen malfunction.
