[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0044] Example 1

[0045] See Figure 1-5 A metal casting processing waste gas treatment device includes a main body component 1, the main body component 1 includes: a treatment frame 11, the rear side wall of which is connected to an air outlet 13; an air inlet pipe 12, which is connected to the end of the air outlet 13 away from the treatment frame 11 through an air pump, the treatment frame 11 is provided with a chemical solution, and the air outlet 13 is provided below the liquid level of the chemical solution; a treatment component 2 is provided on the treatment frame 11, and the treatment component 2 includes: a turntable 21, which penetrates and is rotatably connected to the right side wall of the treatment frame 11; a motor 211 is provided on the right side wall of the treatment frame 11 , the output shaft of the motor 211 is fixedly connected to the right side wall of the turntable 21; the rod body 22 is symmetrically arranged on the left side wall of the turntable 21; the movable door 23 is slidably connected to the left side wall of the processing frame 11; the side block 231 is symmetrically arranged on the outer side wall of the movable door 23; the electric push rod 232 is symmetrically arranged on the outer side wall of the turntable 21, and the top of the electric push rod 232 is fixedly connected to the side block 231 respectively; the filter frame 24 is arranged on the left side wall of the turntable 21, and the filter frame 24 is located below the movable door 23; the collection frame 25 is arranged at the bottom of the filter frame 24. The processing frame 11 and the rod body 22 are provided with a cleaning mechanism 26. The cleaning mechanism 26 comprises: a base plate 261 fixedly connected to the front wall of the processing frame 11; a second electric push rod 262 disposed on the top of the base plate 261; a connecting plate 263 fixedly connected to the right output shaft of the second electric push rod 262; a sliding rod 264 fixedly connected to the left wall of the connecting plate 263, the left end of the sliding rod 264 passing through and slidably connected to the right wall of the processing frame 11; and a scraper 265 slidably connected to the interior of the processing frame 11 and fixedly connected to the left end of the sliding rod 264. The filter frame 24 and the collection frame 25 are slidably connected via a slide block.

[0046] During use, the staff leads the waste gas generated during the metal casting processing to the air inlet pipe 12, and the air pump transports the gas in the air inlet pipe 12 to the inside of the treatment frame 11 through the air outlet 13, and the treatment component 2 treats the waste gas: the air outlet 13 is located below the liquid level of the chemical solution in the treatment frame 11, so that the gas ejected from the air outlet 13 contacts the chemical solution, which is convenient for reacting with harmful substances. At the same time, the staff starts the motor 211, and the motor 211 drives the turntable 21 and the rod body 22 to rotate. When the rod body 22 rotates, the chemical solution is stirred, so that the gas and the chemical solution are more fully mixed, thereby improving the reaction efficiency. The gas that has completed the reaction with the chemical solution is directed to the adsorption mechanism 27 for adsorption. After the waste gas treatment is completed, the staff controls the electric push rod 232 to extend, and the electric push rod 232 drives the movable door 23 to lift upward through the side block 231, and the waste liquid inside the treatment frame 11 flows into the filter frame 24. The filter frame 24 filters out the solid impurities in the waste liquid and mixes them with the collection frame 25. The waste liquid in the part is treated separately. When the chemical solution is discharged, the cleaning mechanism 26 cleans the inner wall of the treatment frame 11 to prevent impurities generated by the reaction from adhering to the inner wall of the treatment frame 11 and affecting the normal reaction effect of the next clean chemical solution: when the turntable 21 drives the rod body 22 to rotate and stir the chemical solution, the scraper 265 is initially located on the side close to the turntable 21. When the chemical solution inside the treatment frame 11 is discharged, the staff controls the electric push rod 262 to retract, and the electric push rod 262 drives the connecting plate 263 and the sliding rod 264 to move to the left. The sliding rod 264 drives the scraper 265 to slide to the left. When the scraper 265 slides, the impurities adhered to the inner wall of the treatment frame 11 are scraped to the movable door 23 for the staff to clean, so as to avoid affecting the normal reaction effect of the next chemical solution. After cleaning the impurities on the scraper 265, the staff controls the electric push rod 262 to extend, and the scraper 265 returns to the far right to facilitate the next waste gas treatment. When the waste liquid in the collecting frame 25 is almost full, the staff slides the collecting frame 25 out of the bottom of the filter frame 24 through the chute slider, so that the staff can process the waste liquid in the collecting frame 25.

[0047] Example 2

[0048] On the basis of the first embodiment, an auxiliary function is added.

[0049] See Figure 1-5 The air outlets 13 are symmetrically arranged in multiple groups. A movable plate 266 is rotatably connected to the inner wall of the scraper 265, and the rod 22 sequentially passes through the movable plate 266. The processing frame 11 is provided with an adsorption mechanism 27, which includes: a tube 271, which is connected to the top of the processing frame 11; an adsorption frame 272, which is arranged at the top of the processing frame 11 and is connected to the tube 271; and an adsorption layer 273, which is symmetrically and movably connected to the adsorption frame 272.

[0050] The multiple gas outlets 13 increase the contact area between the gas and the chemical solution, thereby accelerating the reaction speed and improving the efficiency of waste gas treatment. The scraper 265 drives the movable plate 266 to move together when moving. The movable plate 266 processes the impurities adhered to the outer wall of the rod body 22. Since the scraper 265 is rotatably connected to the movable plate 266, the movable plate 266 does not affect the normal rotation of the rod body 22 while cleaning the rod body 22. The gas after reacting with the chemical solution enters the adsorption frame 272 through the tube 271. The multiple adsorption layers 273 set on the adsorption frame 272 sequentially adsorb water vapor and impurities in the gas, thereby enhancing the treatment effect. As the use time of the adsorption layer 273 increases, its adsorption effect also weakens. The staff can remove the adsorption layer 273 from the adsorption frame 272 by lifting it, which is convenient for regular replacement to avoid affecting the adsorption effect.

[0051] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
