Automatic control system for purifying sea sand

The invention provides an automatic control system for purifying sea sand. If the electrode indication value of the content of chlorine ions in the current sea sand is higher than the required value of the content of the chlorine ions in the sea sand, a central control system controls a sand washing...

Beschreibung
Zusammenfassung:	The invention provides an automatic control system for purifying sea sand. If the electrode indication value of the content of chlorine ions in the current sea sand is higher than the required value of the content of the chlorine ions in the sea sand, a central control system controls a sand washing wheel motor to reduce the rotating speed and controls an electric control water outlet valve to open, so that the amount of water for washing the sea sand is increased; and if the electrode indication value of the content of the chlorine ions in waste water after treatment is lower than the required value of the content of the chlorine ions in the waste water, the central control system controls the electric control water outlet valve to open, and the waste water after treatment can be put into use again. By means of the automatic control system for purifying the sea sand, the problem that an existing sea sand purifying production line cannot perform automatic adjustment in real time according to the chlorine ion
