Each system has a specific solid-liquid ratio of quartz sand to pickling solution. By comparing the reference experiments, the effect of pickling solution on the removal of impurities in quartz sand under different solid-liquid ratios can be studied. During pickling, the microcontroller has a built-in PID algorithm and DCS control system. Through the setting of the monitoring module, the density change and solid-liquid ratio of the mixture in each pickling solution supply component can be measured. The DCS control system transmits the control signal to the pump on the pickling tank and adjusts the amount of pickling solution supplied by the pump, thereby realizing the dynamic adjustment of the solid-liquid ratio and the adjustment of the pickling solution in each pickling solution supply component.

[0027] 2) During operation of this invention, when performing acid washing of quartz sand, the drive motor outputs a set power speed. After the drive motor outputs the speed, it drives the camshaft to rotate. After the camshaft rotates, through the setting of the cam and the return spring, it drives the outer and inner vibrating frames to move synchronously back to the set stroke. After the outer and inner vibrating frames move synchronously, the spiral hinge then moves the quartz sand, which can effectively improve the scouring effect of the acid washing solution on the quartz sand, thereby improving the acid washing effect of the acid washing solution on the quartz sand.

[0028] 3) When the present invention is in operation, during the pickling of quartz sand, the spiral conch lifts the quartz sand upwards, and through the cooperation of the return port and the discharge port, the quartz sand is circulated for pickling. When the quartz sand enters between the outer and inner spiral cylinders, it is effectively improved by the action of multiple sets of cleaning rubber rods, thereby effectively improving the collision degree between the quartz sand and the cleaning acid, and thus effectively improving the pickling effect of the quartz sand. Through the improvement of the pickling effect, the pickling degree of the pickling solution on the quartz sand under different solid-liquid ratio conditions can be accurately and quickly measured.
