[0032] Working principle: when in use, the staff passes the liquid into the funnel 4, and the liquid falls on the filter plate 9. After being filtered by the filter plate 9, the solid impurities inside it remain on the top of the filter plate 9. When there are too many impurities on the top of the filter plate 9, the staff pours the liquid from the other end of the first baffle 10 into the filter box 3. The liquid is filtered through the filter plate 9 on the other side. At this time, the staff rotates the handle 29, the threaded rod 27 rotates, driving the circular block 28 to descend, and the block 28 leaves the slot 26. At this time, the staff can draw out the box door 6, and then start the electric telescopic rod 21. The telescopic end of the electric telescopic rod 21 stretches to push the scraper 22 to move. The scraper 22 pushes the impurities on the top of the filter plate 9 out of the opening 20, which facilitates the cleaning of the impurities. When the cleaning is completed, the staff resets the box door 6, rotates the handle 29, the block 28 enters the slot 26, fixes the box door 6, and reciprocates until the filtration is completed, thereby improving the filtration efficiency. The filtered liquid enters the neutralization box 5. The staff uses the electric heating plate 15 and the temperature sensor 18 to keep the temperature in the box constant. Liquid ammonia and the like are added into the box through the liquid inlet pipe 12 to provide a basis for the preparation. The pH value of the liquid in the box is continuously measured by the pH meter 19 to accurately grasp the preparation results. Finally, the staff starts the solenoid valve 17, and the liquid leaves the neutralization box 5 from the liquid outlet pipe 16.
