The scraper mechanism 7 rotates under the drive of the mixing mechanism 3 to scrape the material attached to the bottom or side of the pickling box 1, so that the mixing is more uniform and the reaction is more sufficient, and then the moving mechanism 2 is started to drive the mixing mechanism 3 and the scraper mechanism 7 to move back and forth up and down, so that the pickling solution is mixed evenly and the reaction is sufficient.

[0037] Specifically, the moving mechanism 2 includes a fixed frame 201, the longitudinal section of which is in an inverted "U" shape, and electric slide rails 202 are vertically fixed on the inner walls on both sides of the fixed frame 201 by bolts, a slider 204 is slidably connected to the outer wall of one side of the electric slide rail 202, and a cross plate 203 is horizontally installed on the outer wall on the side opposite to the two sliders 204.

[0038] As can be seen from the above, starting the electric slide rail 202 can drive the movement of the slider 204, and further drive the movement of the mixing mechanism 3 and the scraping mechanism 7.

[0039] Specifically, the mixing mechanism 3 includes a motor 301, which is fixed by bolts at the center position of the bottom outer wall of the horizontal plate 203. The bottom end key of the output shaft of the motor 301 is connected with a transmission shaft 302. One end of the transmission shaft 302 passes through the top outer wall of the pickling box 1. The transmission shaft 302 is located at the vertical center line inside the pickling box 1.

[0044] As can be seen from the above, after the pickling work is completed, the solenoid valve 6 is opened, and the quartz sand and pickling liquid can be discharged from the discharge pipe 5.

[0045] Working principle: When in use, pour the solution of fluorosilicic acid and hydrofluoric acid into the pickling box 1 from the feed hopper 4, then pour quartz sand into the pickling box 1, start the motor 301 to drive the transmission shaft 302 and the stirring rod 303 to mix the pickling solution and the quartz sand, and use the acidic substance to physically or chemically remove the dirt and harmful substances on the surface of the quartz sand. The scraper mechanism 7 rotates under the drive of the mixing mechanism 3, and the materials attached to the bottom or side of the pickling box 1 are scraped by the scraper 702, the scraper blade 1 703 and the scraper blade 2 705, so that the mixing is more uniform and the reaction is more sufficient, and then start the electric slide rail 202 to drive the slider 204 to move up and down reciprocatingly, and then drive the mixing mechanism 3 and the scraper mechanism 7 to move up and down reciprocatingly, so that the pickling solution is mixed evenly and reacts fully. After the pickling work is completed, open the solenoid valve 6, and the quartz sand and pickling solution can be discharged from the discharge pipe 5.
