[0027] Specifically, a pair of supporting legs 300 are fixedly connected to the bottom end of the circular shell 10 , and both ends of the circular shell 10 are provided with round openings.

[0028] In this embodiment, the support legs 300 provide stable support for the circular housing 10 , and the circular opening will neither interfere with the rotation of the screen drum 50 nor interfere with the movement of the sliding arc sheet 120 .

[0035] The working principle and use process of the utility model are as follows: the clay sand (including molding sand and castings) enters the feed hopper 20, and the molding sand and castings pass through the opening 60 together and fall into the screen drum 50. At this time, the molding sand and castings bury the multiple cooling pipes 462, and the sealing arc sheet 70 faces downward, so the molding sand in the screen drum 50 will not be separated from the screen drum 50, the molding sand and castings are cooled evenly, the cooling time is long, and the cooling effect is good. The electric telescopic rod 210 is started to shrink, and the two sliding arc sheets 120 move closer to each other and fit on the outer gear ring 80. On the top, the sealing of the opening 60 can be achieved, and then the outer gear ring 80 is driven to rotate by the driving mechanism 90, and the outer gear ring 80 drives the screen drum 50 to rotate. At this time, the screening of molding sand and castings can be achieved. The large castings stay in the screen drum 50, and the small molding sand passes through the screen drum 50 and is discharged through the discharge port 30; when the casting needs to be cleaned, the opening 60 is facing downward, and then the electric telescopic rod 210 is started to extend to the maximum length. At this time, the length of the opening 60 is the longest, and the castings fall automatically, and the fall is sufficient without any residue.
