Simultaneously open the stirring device 6, the water-sand mixing tank is equipped with a double-layer stirring device, and the device is controlled by a frequency converter. influential. The liquid level sensor 5 (the liquid level sensor here is a plug-in differential pressure liquid level gauge) prevents the system from inaccurate measurement of the liquid level gauge due to sand in the water. When reaching the limited liquid level, close the valve and stop thepipeline pump 103 at the same time.

打开第二开关阀109，第二开关阀109处装有手动跟电动两只阀门，手动阀门为检修阀，平常为常开状态，只有当检修或者特殊情况时才用手动阀门关闭进水。启动渣浆泵110，调节第一开关阀102门查看第二流量计112到需要流量。当水沙混合罐上的液位传感器5低于某数值时液位计共有4段设定值，低于最低点设定值时为工频供水，在第2-3点之间时，系统根据液位的高低不同采用变频供水，当液位高于最高点的液位时管道泵0HZ运行。Open the second on-offvalve 109, the second on-offvalve 109 is equipped with manual and electric two valves, and the manual valve is an inspection valve, which is usually in a normally open state.

混合液体通过分沙装置将湿沙分离出来水沙分离器采用旋流分沙器两台串联使用，分沙器的体积不宜过大，如采用大容量的分沙器，对水沙分离的效果将小于采用小型分沙器的效果，湿沙经过称重传感器得到湿沙的重量，然后进入烘干装置，水分以水蒸气模式被排掉，得到干沙湿沙采用分段计量，分段烘干。干沙经过称重后返回沙箱；烘干前后的重量差值就是湿沙所带水分的重量，通过试验软件保存到数据库。The mixed liquid is separated from the wet sand through the sand separator. The water and sand separator uses two cyclone sand separators in series. The volume of the sand separator should not be too large. If a large-capacity sand separator is used, the effect of water and sand separation It will be less than the effect of using a small sand separator. The wet sand passes through the load cell to obtain the weight of the wet sand, and then enters the drying device, and the water is drained in the steam mode to obtain dry sand. Dry. The dry sand is weighed and returned to the sandbox; the weight difference before and after drying is the weight of the moisture carried by the wet sand, which is saved to the database through the test software.
