[0032] By adopting the above technical solution, the device can prevent foreign matter from entering the device through the cooperation of structures such as the mesh ring 71 and the closed frame 73 when necessary, thereby better meeting the working needs in different situations.

During the grinding work, the staff can start the fan 85 in the dust collecting device 8. Under the action of the fan 85, the flying dust during grinding passes through the conveying pipe 81 with the air into the collecting box 83, and then the dust is blocked by the filter cloth 84 and remains in the collecting box 83, thereby reducing the possibility of the dust causing adverse effects on the surrounding personnel or the environment. After the grinding is completed, the fan 85 can be turned off, and the staff can unscrew the threaded block 82 to take out the collected dust.

[0036] The structure and principle of the first box body 1 and the structure above it, the discharging assembly 3 composed of the mounting groove, the extrusion block, the eccentric wheel, the first motor, the third box body, the spring, the first filter plate, the closing door and the third filter plate, the grinding assembly 4 composed of the grinding roller, the third motor, the driving gear and the driven gear, the continuous pickling assembly 5 composed of the stirring shaft, the pipeline pump, the second box body, the second motor, the observation window, the second filter plate and the partition, and the electric heating rod 6 are disclosed in a stone The quartz sand continuous pickling device has been disclosed. Its working principle is that when in use, the third motor and the electric heating rod are turned on, the third motor drives the driving gear to rotate, the driving gear drives the driven gear to rotate by meshing with the driven gear, the driven gear drives the second rotating shaft to rotate, and then drives the grinding roller to rotate to physically crush the large particles of quartz sand. The crushed quartz sand enters the interior of the heating tank and pours the quartz sand into the interior of the first box through the slot on the top of the first box. After the electric heating rod heats the quartz sand, the solenoid valve on the third discharge pipe is opened to discharge the quartz sand. The first discharge pipe is connected to the external pump, and the solenoid valve on it is opened to extract the reacted acid and most of the impurities through the second filter plate, and then acid is added to the second box through the acid adding pipe, and the pipeline pump is opened to discharge the acid and quartz sand into the lower part of the inner partition of the second box, and the corresponding second electric motor is continued to be opened. The machine drives the stirring blades on the outer side of the corresponding stirring shaft to continue to accelerate the reaction. After observing the reaction again, the solenoid valve on the second discharge pipe is opened to discharge the acid and quartz sand after the secondary reaction into the interior of the third box body. The first motor is turned on, and the eccentric wheel is driven to rotate by the first motor. The eccentric wheel squeezes the extrusion block and then squeezes the first filter plate to make it reciprocate and squeeze the spring. The impurities in the quartz sand are mainly metal impurities headed by iron. The impurities are adsorbed by the first filter plate, and the quartz sand is intercepted by the third filter plate and retained on the inner bottom side of the third box body. The acid is discharged through the fourth discharge pipe.

After the heating is completed, the solenoid valve at the bottom of the first box body 1 is opened, so that the quartz sand passes through the upper connecting pipe 24 in the separation connection device 2 and enters the connection box 21, and rolls on the inclined filter screen 23. The staff can start the vibrator 26 to drive the filter screen 23 to vibrate, thereby preventing the filter screen 23 from being blocked. The filter screen 23 is made of elastic material. Unqualified fine particles in the quartz sand pass through the filter screen 23 and remain in the connection box 21, while qualified quartz sand passes through the lower connecting pipe 27 and enters the continuous pickling component 5. Then the staff continuously pickles the quartz sand through the continuous pickling component 5, and sends it to the discharging component 3 after continuous pickling, and operates the discharging component 3 to The quartz sand is filtered, and the acid is discharged from the discharging component 3, and then the staff can take out the quartz sand, and the work is completed. In addition, the staff can unscrew the blocking block 25 to take out the unqualified fine quartz sand particles in the connecting box 21, and the thermal insulation cotton 22 plays a role in preventing heat loss; when necessary, the staff can start the electric telescopic rod 72 in the closing device 7, thereby driving the closing frame 73 to descend until the closing frame 73 and the mesh ring 71 are tightly attached to each other, thereby preventing foreign impurities from entering the device. During the grinding work, the staff can start the fan 85 in the dust collecting device 8. Under the action of the fan 85, the flying dust during grinding passes through the conveying pipe 81 with the air into the collecting box 83, and then the dust is blocked by the filter cloth 84 and remains in the collecting box 83, thereby reducing the possibility of dust causing adverse effects on surrounding personnel or the environment. After the grinding is completed, the fan 85 can be turned off, and the staff can unscrew the threaded block 82 to take out the collected dust.
