Specifically, dewaxing precision casting is a casting method in which a wax pattern is formed into a desired shape, the wax pattern is melted and lost by heating, and molten metal is injected into a blank shell to form a casting, in the dewaxing precision casting process, a natural gas roasting device is required to be used for roasting a mould shell, tail gas is generated in the roasting process, the tail gas generated in the roasting process possibly contains pollutants such as sulfur dioxide, nitrogen oxides, particulate matters and the like, and if the tail gas is directly discharged without treatment, obvious pollution is caused to the atmospheric environment, and meanwhile, the damage is possibly caused to the health of a human body, so that the tail gas generated by the natural gas roasting device is required to be treated in order to protect the environment and the health of workers; the existing roasting exhaust gas treatment device sprays purifying liquid on the exhaust gas to adsorb impurities in the exhaust gas, the impurities adsorbed by the purifying liquid are intercepted by a filter box and stay on the surface of the filter box, the purified exhaust gas is discharged out of a purifying tower, but when more impurities are adhered on the surface of the filter box, the filter box is required to be taken out of the purifying tower after the purifying work is finished, and then the purifying work is cleaned, so that the trouble is caused, in the cleaning process of the filter box, the normal operation of the purifying work is also influenced, and in addition, if the filter box is blocked by the impurities, the passing of the exhaust gas and the spraying liquid is influenced, and the whole purifying efficiency is further influenced;
Therefore, in order to solve the above-mentioned problem, when the embodiment is used, the exhaust gas discharge pipeline of the natural gas roasting equipment is connected with the air inlet pipe 2, the exhaust gas enters the purifying box 1 through the air inlet pipe 2, then the pump body 20 is started, the pump body 20 pumps the purifying liquid in the liquid storage box 19, and the purifying liquid is sprayed from the spray head 24 after passing through the hose 21 and the connecting pipe 23, so that the exhaust gas is sprayed, impurities in the exhaust gas can be adsorbed by the purifying liquid and fall on the surface of the filter plate 4, and the purification of the exhaust gas can be realized;
In addition, in the spraying process of the purifying liquid, the motor III 18 can be utilized to drive the threaded rod III 25 to rotate, so that the displacement plate 28 transversely moves, when the through hole column 30 is aligned to the filter hole 31, the electric push rod II 26 is started and drives the fixing plate 29 to ascend, so that the through hole column 30 passes through the filter hole 31, impurities blocking the filter hole 31 can be lifted upwards, then the through hole column 30 is reset and transversely moves to dredge the rest filter holes 31, so that the impurities blocking the filter hole 31 can be lifted upwards in the spraying process, the impurities are far away from the filter hole 31, the situation that tail gas and spraying liquid pass through the filter hole 31 due to the blocking of the filter hole 31 by the impurities is avoided, the purifying efficiency is improved, meanwhile, the manual cleaning process of the filter hole 31 by personnel is omitted, and the purifying liquid is convenient;
In order to avoid the situation that the filter holes 31 are blocked again due to the fact that the impurities can fall on the surface of the filter plate 4 and the impurities can be displaced under the action of external force of spray liquid and tail gas, so that the dredging effect is affected, when the fixing plate 29 moves transversely, the collecting box 9 moves transversely and synchronously with the fixing plate 29 under the action that the motor III 18 drives the threaded rod I7 to rotate, the through holes 17 are aligned with each row of filter holes 31 in sequence, after the through hole columns 30 pass through the filter holes 31, the through holes 17 continue to ascend and pass through until the upper end surfaces of the through hole columns 30 are aligned with the lower end surfaces of the inner cavity walls of the collecting box 9, at the moment, the electric push rod I10 is started to drive the scraping plate 16 to move from right to left, and the impurities attached to the top of the through hole columns 30 can be pushed leftwards, so that the impurities are separated from the end parts of the through hole columns 30 and transferred into the collecting box 9, and the situation that the impurities ejected by the through hole columns 30 fall on the surface of the filter plate 4 are displaced under the action of external force of the spray liquid and the tail gas, and the filter holes 31 are blocked again is avoided;
Moreover, because the through hole 17 exists at the bottom of the collecting box 9, the tail gas possibly enters the collecting box 9 through the through hole 17, so that the impurities of the collecting box 9 are blown out to the collecting box 9 and return to the surface of the filter plate 4 again, and the dredging effect is affected, therefore, when the scraper 16 transversely moves to push the impurities at the top of the through hole column 30, the impurities are pushed to the position between the box cover 15 and the baffle 12, then the motor II 13 drives the threaded rod II 14 to rotate, so that the baffle 12 descends, the bottom of the baffle is attached to the bottom of the inner cavity of the collecting box 9, at the moment, the impurities are in a closed space, then the through hole column 30 is separated from the through hole 17 again, and the subsequent dredging operation is carried out, and the impurities are in the closed space every time the impurities are carried into the collecting box 9 by the through hole column 30, so that the tail gas is prevented from entering the collecting box 9, and the impurities are blown down to the surface of the filter plate 4 again, and the dredging effect is affected;
the purified tail gas can be discharged from the gas outlet pipe 33, the spray liquid can be discharged from the liquid discharge pipe 6, and impurities in the collecting box 9 can be cleaned by periodically opening the box cover 15.
In this embodiment, as shown in fig. 9, a motor one 3 is fixedly connected to the middle part of the upper end surface of the purifying box 1, and the output end of the motor one 3 is fixedly connected to the middle part of the upper end surface of the rotating plate 22.
Specifically, in the process of purifying liquid spraying tail gas, the motor I3 can be utilized to drive the connecting pipe 23 to reciprocally rotate for a certain angle so as to change the angle of the spray head 24, and the rotating angle of the connecting pipe 23 is limited, so that the hose 21 cannot be wound, the spraying range is enlarged, and the spraying uniformity is improved.
