The finished material of the sand washer directly enters the dewatering screen for dehydration, and the slurry water discharged from the sand washer enters the cleaning tank of the equipment and is pumped to the separator through the vacuum high-pressure pump at the bottom for J separation and concentration. The fine sand enters the dewatering screen through the sedimentation sand nozzle, and other wastewater, mud, powder and impurities enter the return water tank through the overflow port of the high-pressure separator for discharge.
When the dewatering screen acts on some materials with low mud content, it can also be used alone without sand washing machine. Because quartz sand generally has low mud content, using sand washing machine to wash sand not only consumes energy, but also has poor effect. The important thing is that the investment cost of dewatering screen is lower than that of sand washing machine.
The dewatering screen adopts double motor self synchronization technology, universal eccentric block and adjustable amplitude vibrator. It is mainly composed of screen box, vibration exciter, support system and motor. Two unconnected vibrators operate synchronously and reversely. The centrifugal force generated by the two groups of eccentric masses is superimposed along the component force in the vibration direction and offset by reverse centrifugation, so as to form a single excited vibration along the vibration direction and make the screen box move back and forth in a straight line.
