[0003] For example, patent number CN105883818A discloses a quartz sand pickling equipment.

Based on this, the present invention provides a dynamic solid-liquid ratio adjustment system for quartz sand pickling to solve the problems raised in the above background technology. Summary of the invention

[0010] The beneficial effect of adopting the above further scheme is that when the system is working, the quartz sand injection pipe is set to add equal amounts of quartz sand to be pickled into the interior of the injection barrel in each quartz sand pickling mechanism, and then a subsequent quartz sand comparison experiment is carried out. The solenoid valve is set to control the discharge state of the feed pipe.

[0011] Furthermore, the guide module includes a transmission motor installed on the pickling frame and a camshaft rotatably connected to the pickling frame. The output shaft end of the transmission motor is transmission-connected to the gear cylinder through a first belt. Bevel gears are installed on the output shaft end of the transmission motor and the camshaft. The two bevel gears are meshed with each other. A protrusion is installed on the camshaft. An outer vibration frame is slidably connected to the pickling frame. The inner vibration frame is rotationally connected to the outer vibration frame. A reset spring is installed between the outer vibration frame and the pickling frame. The protrusion is transmission-adapted to the outer vibration frame.

After the transmission motor outputs the speed, it drives the camshaft to rotate.

The data ends of the temperature probe, solid-liquid ratio measurement and control element, PH electrode probe and acid concentration meter are all connected to the microcontroller data.

[0016] The beneficial effect of adopting the above further scheme is that when the quartz sand is pickled, the reaction temperature during the pickling process of the quartz sand is monitored in real time by setting the temperature probe, and the solid-liquid ratio ratio during the pickling process of the quartz sand is monitored in real time by setting the solid-liquid ratio measurement and control element. The solid-liquid ratio measurement and control element is a public component in the prior art and will not be described in detail here. The pickling state of each quartz sand pickling mechanism is monitored in real time by setting the pH electrode probe and the acid concentration meter.

[0017] The microcontroller has built-in PID algorithm and DCS control system. Through the setting of monitoring module, the density change and solid-liquid ratio of the mixture in each pickling liquid supply component can be measured. The DCS control system transmits the control signal to the pump body on the pickling tank to adjust the pickling liquid supply of the pump body, thereby realizing the dynamic adjustment of the solid-liquid ratio in each pickling liquid supply component and the adjustment of the pickling liquid;

[0018] Specifically, when the regulating system is working, the solid-liquid ratio setting parameters in each quartz sand pickling mechanism are different, and the four solid-liquid ratio setting adjustments are 1:0.8, 1:0.9, 1:1 and 1:1.1 respectively. By comparing the reference experiment, the removal effect of the pickling solution on impurities in quartz sand under different solid-liquid ratios is studied;

[0020] Furthermore, the spiral filtering mesh is provided with filtering holes at equal intervals, and the axis of the filtering holes is parallel to the axis of the lifting barrel.

[0021] The beneficial effect of adopting the above further scheme is that when the device is completed with the reference and comparative experiment, and the quartz sand after pickling in each quartz sand pickling mechanism needs to be discharged in turn, the spiral filter mesh lifts the quartz sand upward, and the pickling liquid is discharged through the liquid outlet valve.

[0026] 1) When the present invention is working, four groups of reference and comparative experimental systems are set up for pickling of quartz sand, and each group of systems has a specific solid-liquid experimental ratio of quartz sand to pickling solution. By comparing the reference experiments, the removal effect of the pickling solution on impurities in the quartz sand under different solid-liquid ratios is studied. During pickling, the single-chip microcomputer is equipped with a built-in PID algorithm and a DCS control system. Through the setting of the monitoring module, the density change and the 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 body on the pickling box, adjusts the pickling solution supply amount of the pump body, and then realizes the dynamic adjustment of the solid-liquid ratio in each pickling solution supply component and the adjustment of the pickling solution.

[0027] 2) When the present invention is working, when the pickling operation of quartz sand is carried out, the transmission motor outputs the speed at the set power. After the transmission motor outputs the speed, it drives the camshaft to rotate. After the camshaft rotates, the outer vibration frame and the inner vibration frame are driven to reset synchronously within the set stroke through the setting of the protrusion and the reset spring. After the outer vibration frame and the inner vibration frame are synchronously displaced, the spiral auger drives the quartz sand to move, which can effectively improve the flushing degree of the pickling liquid on the quartz sand, and then improve the pickling effect of the pickling liquid on the quartz sand.

When the quartz sand enters between the outer rotating cylinder and the inner rotating cylinder, it is effectively improved through the action of multiple groups of cleaning glue sticks, thereby effectively improving the collision degree between the quartz sand and the cleaning acid solution, and then 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.
