[0002] Quartz crystal has piezoelectric effect, and will produce mechanical vibration when it is subjected to the effect of external alternating electric field. When the frequency of alternating electric field is the same as the natural frequency of quartz crystal, the vibration becomes very strong, which is the core component of quartz crystal oscillator. When quartz crystal is used, it needs to be ground to obtain high-quality quartz wafers. The waste liquid generated during the processing needs to be treated. After searching, the Chinese patent publication number is CN216737953U, which discloses a waste liquid treatment device for metal processing, including a treatment box, a cover plate is provided on the top of the treatment box, and connecting plates are fixedly installed on both sides of the bottom of the cover plate and located inside the treatment box. The utility model is provided with a treatment box, a cover plate, a sealing plug, a sealing sleeve, an operating handle, a card plate, a connecting plate, a magnetic plate, a liquid drop hole, a guide cover, a primary filter screen, a limit ring, a water inlet pipe, a sealing flange, a waste liquid pipe, a drain pipe, a moving rod, a scraper The plate, drain trough, sealing baffle, storage groove, spring, connecting groove, toggle rod and sealing card slot cooperate with each other, so that the device has the function of filtering and adsorbing iron filings impurities in the waste liquid, preventing the discharge of waste liquid containing iron filings, and avoiding pollution to the environment. At the same time, it solves the problem that the waste liquid contains iron filings, and the waste liquid is generally discharged directly without filtering and removing the iron filings, resulting in the iron filings in the waste liquid causing pollution to the environment. The above-mentioned existing technical solutions have the following defects: there will be some solid impurities in the quartz chip grinding waste liquid, and there will be residual impurities in the filter screen after the waste liquid is treated. There is no corresponding cleaning structure for dredging, and long-term use is prone to blockage, affecting the use of the treatment device, and the residual impurities inside the device cannot be cleaned, reducing the practicality of the environmental protection treatment device. Therefore, a quartz chip grinding waste liquid environmental protection treatment device is proposed to solve the above-mentioned problems. Utility Model Content

[0030] In summary, the environmental protection treatment device for quartz wafer grinding waste liquid, through the driving mechanism 6, the annular plate 7, the dredging mechanism 8 and the scraping mechanism 9, performs solid-liquid separation treatment on the quartz wafer grinding waste liquid, and then the inside of the treatment device needs to be cleaned. First, the motor 61 is started to drive the rotating shaft 62 to rotate. The rotating shaft 62 drives the horizontal plate 63 to rotate under the support of the circular ring 64, thereby driving the vertical plate 65, the dredging mechanism 8 and the scraping mechanism 9 to rotate at the same time. When the motor 61 is started, the cleaning liquid is injected into the treatment cylinder 1 and the filter cylinder 4 through the feed pipe 10; the dredging mechanism 8 is used to clean the solid impurities remaining in the filter holes on the filter cylinder 4. The vertical plate 65 drives the rectangular block 81 and the slide rod 82 to move while rotating around the filter cylinder 4. With the cooperation of the annular plate 7, the slide rod 82 drives the rectangular block 81 and the mounting plate 83 to reciprocate up and down. When the dredging block 88 is no longer in contact with the filter hole, it pushes the arc plate 86 to move under the support of the cross bar 84 and compresses the fixing spring 8 7. The arc plate 86 continues to rotate, and the tension of the fixed spring 87 pushes the dredging block 88 to extend to other filter holes again, and so on. The arc plate 86 rotates around the filter cartridge 4 to ensure that the dredging block 88 can contact each filter hole. The dredging block 88 is used to clean the solid impurities on the filter cartridge 4, thereby achieving the purpose of the cleaning structure to dredge the filter screen; secondly, the vertical plate 65 rotates while driving the scraping mechanism 9 to move. The movable frame 92 in the mounting frame 91 is connected by a telescopic spring 93 to ensure that the scraper 94 always fits the inner wall of the treatment cylinder 1. The scraper is used to clean the residual impurities on the inner wall of the treatment cylinder 1, thereby achieving the purpose of cleaning the interior of the device, solving the problem that there will be some solid impurities in the quartz wafer grinding waste liquid, and there will be residual impurities in the filter screen after the waste liquid is treated. There is no corresponding cleaning structure for dredging, and long-term use is prone to cause blockage, affecting the use of the treatment device, and the impurity residues inside the device cannot be cleaned.
