Method, device and system for controlling water content of machine-made sand and sand making equipment
The invention provides a method, device and system for controlling the water content of machine-made sand and sand making equipment. The method comprises the steps that the current weight value of finished machine-made sand and the flow target value of the water content needed by the finished machine-made sand are obtained; the current flow value of the water content of the finished product machine-made sand is monitored; and the opening degree of a valve port of a proportional overflow valve is adjusted according to the error between the flow target value and the current flow value, so that the water content of the finished machine-made sand reaches the flow target value. According to the invention, the technical problem of inaccurate control of the water content of the machine-made sand in the prior art is solved.
本发明提供了一种机制砂含水量的控制方法及装置、系统、制砂设备，该方法包括：获取成品机制砂的当前重量值以及所述成品机制砂所需含水量的流量目标值；监测所述成品机制砂含水量的当前流量值；根据所述流量目标值与所述当前流量值之间的误差调节比例溢流阀的阀口开度，使得所述成品机制砂的含水量到达所述流量目标值。通过本发明，解决了相关技术中机制砂含水量控制不精确的技术问题。
