The baffle plates 17 are uniformly arranged in the slag scraping pool 1, the baffle plates 17 incline towards the rotating belt 11, and the baffle plates 17 are uniformly provided with filter holes 18; the diameter of the filter holes 18 on the adjacent partition plates 17 is gradually reduced, and the diameter of the filter holes 18 far away from the waste residue box 13 is larger than that of the filter holes 18 close to the waste residue box 13, and the top of the partition plates 17 close to the waste residue box 13 is positioned in the waste residue box 13;
The water inlet end of the slag scraping pool 1 is communicated with the medicine mixing pool, the water outlet end of the slag scraping pool 1 is communicated with the purifying pool, and the water inlet end and the water outlet end of the slag scraping pool 1 are both close to the bottom; the waste liquid is reacted in the medicine mixing tank in a medicine adding mode, so that pollutants in the waste liquid are coagulated and floated; and discharging the mixed waste liquid into a slag scraping pool 1, filtering the mixed waste liquid in the slag scraping pool 1, discharging the filtered waste liquid into a purifying pool, and finally discharging the evolved waste liquid into a paint spraying workshop for recycling after the treatment of the purifying pool.
The specific working flow is as follows: when waste liquid is treated, the rotating belt 11 rotates to drive the scraping plate 12 to move, the scraping plate 12 is turned over to be below the rotating belt 11 and then contacts the liquid level of the waste liquid in the slag scraping pool 1, and floating impurities are pushed to the direction of the waste liquid box 13 along with the movement of the scraping plate 12 until the impurities are pushed into the waste residue box 13; moreover, the scraping plate 12 scrapes along the inner wall surface of the inner side of the scraping tank 1, and when scraping impurities adsorbed on the inner wall of the scraping tank 1, the scraping plate 12 is prevented from flowing away from gaps between two ends of the scraping plate 12 and the side wall of the scraping tank 1 in the process of pushing the impurities, so that the solid-liquid separation efficiency of the scraping plate 12 is influenced, the waste liquid filtering efficiency is improved, meanwhile, the cleaning degree of the scraping tank 1 is maintained, the time for cleaning the scraping tank 1 by workers in each filtering is shortened, the solid-liquid separation efficiency of the scraping tank 1 is improved, and the waste gas and waste liquid treatment system efficiency is further improved;
when impurities are scraped into the waste residue box 13, the scraping plate 12 passes over the waste residue box 13, and the scraping plate 12 contacts the upper half part of the cleaning plate 15; along with the movement of the scraping plate 12, the cleaning plate 15 is extruded, the cleaning plate 15 slides along the inclined surface of the scraping plate 12, impurities adhered to the surface of the scraping plate 12 are scraped by the cleaning plate 15 and drop into the waste residue box 13, so that the cleaning degree of the surface of the scraping plate 12 is improved, the situation that the scraping plate 12 carries excessive residual impurities to contact waste liquid again to increase the impurity content in the waste liquid is avoided, the solid-liquid separation efficiency of the waste liquid is improved, and the efficiency of a waste gas-waste liquid treatment system is further improved; the scraper 12 drives the cleaning plate 15 to move, and meanwhile, the cleaning plate 15 slides in the waste residue box 13 to scrape the impurities in the waste residue box 13, so that the impurities are prevented from being dried and adhered on the draining holes 14 after being drained, the draining effect of the draining holes 14 is affected, and the long-time draining effect of the draining holes 14 is improved; the water drained from the draining holes 14 flows back to the slag scraping pool 1 again through the water pipe, so that the waste of water resources in solid-liquid separation is reduced, and the solid-liquid separation effect is improved; in the process that the cleaning plate 15 moves from one side of the waste residue box 13 to the other side, the cleaning plate 15 can be matched with the inner wall of the waste residue box 13 to extrude impurities, water in the impurities is extruded, the utilization of water resources is improved, meanwhile, the drying of the impurities is accelerated, and workers can conveniently take out or process the impurities; in addition, when the waste residue box 13 is installed, a heating wire can be installed in the waste residue box 13, and impurities are heated and dried through the heating wire, so that the impurities are more easily dried into solids, and the impurities are further conveniently taken out;
