Its purpose is to remove impurities in the molding sand, improve the air permeability, compactness and other properties of the molding sand, ensure the smooth progress of the casting process, and improve the quality of castings. However, there are many problems with traditional molding sand pre-treatment devices: 1.

[0022] Working principle: When in use, the pretreated molding sand is put into the interior of the machine body 1 through the feeding hopper. At the same time, the driving motor 7 is started. The start of the driving motor 7 drives the rotation of the eleventh pulley 8 through the output shaft. The rotation of the eleventh pulley 8 drives the synchronous rotation of the twelfth pulley 901, the thirteenth pulley 902 and the third pulley 306 respectively through the fifth belt 903. The rotation of the thirteenth pulley 902 drives the rotation of the third grinding roller 203. The rotation of the third grinding roller 203 drives the rotation of the first gear 205, which is meshed and driven with the second gear 206 at the same time. The rotation of the second gear 206 drives the rotation of the second grinding roller 202. The rotation of the thirteenth pulley 306 drives the screening cylinder 301 to rotate synchronously. The ground molding sand is screened through the rotation of the screening cylinder 301; At the same time, the rotation of the third grinding roller 203 drives the rotation of the second pulley 208. The rotation of the second pulley 208 drives the synchronous rotation of the first pulley 207 through the first belt 209. The rotation of the first pulley 207 drives the rotation of the fourth grinding roller 204. At the same time, the rotation of the second grinding roller 202 drives the synchronous rotation of the sixth pulley 1003 and the fourth pulley 1001 respectively through the second belt 1004. The rotation of the fourth pulley 1001 drives the rotation of the first grinding roller 201. The molding sand entering the interior of the machine body 1 is ground through the rotation of the first grinding roller 201, the second grinding roller 202, the third grinding roller 203 and the fourth grinding roller 204. At the same time, the ground molding sand enters the interior of the screening cylinder 301; The rotation of the sixth pulley 1003 drives the rotation of the first connecting rod 302. The rotation of the first connecting rod 302 drives the synchronous rotation of the connecting frame 303. At the same time, the rotation of the connecting frame 303 drives the synchronous rotation of the electromagnetic plate 304. The magnetic impurities in the molding sand entering the interior of the screening cylinder 301 are adsorbed through the rotation of the electromagnetic plate 304; The rotation of the first grinding roller 201 drives the synchronous rotation of the tenth pulley 210. The rotation of the tenth pulley 210 drives the rotation of the ninth pulley 606 through the fourth pulley 605. The rotation of the ninth pulley 606 drives the seventh pulley 602 to rotate at an accelerated speed through the accelerator 601. At the same time, through the rotation of the third pulley 604, the rotation of the third pulley 604 drives the rotation of the worm 505. The rotation of the worm 505 is meshed and driven with the worm gear 504, thereby driving the rotation of the second connecting rod 502. The rotation of the second connecting rod 502 drives the fan blade 503 to rotate synchronously. The light impurities in the molding sand entering the interior of the machine body 1 are blown through the rotation of the fan blade 503, thereby removing impurities such as leaves, fluff or paper scraps in the molding sand, thus ensuring the effect of using the molding sand for casting. The blown light impurities leave the interior of the machine body 1 through the guide plate 11 and thus fall into the impurity collection box 13; Since the storage door 307 and the screening cylinder 301 are magnetically adsorbed, no internal impurities will fall off during screening. At the same time, the rotation of the twelfth pulley 901 drives the rotation of the first conveying roller 401, and the rotation of the first conveying roller 401 drives the conveyor belt 403 to rotate around the circumference of the second conveying roller 402. The screened molding sand is automatically conveyed through the conveyor belt 403. When the screening is completed, all the electromagnets on the electromagnetic plate 304 and the storage door 307 are powered off, so that the storage door 307 opens, and at the same time, the magnetic impurities adsorbed on the electromagnetic plate 304 all fall off, and are thus conveyed out of the interior of the machine body 1 through the conveyor belt 403, facilitating the cleaning by the operator.

[0023] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
