[0002] In the modern foundry industry, coated sand has become a key material for molding and core making due to its good fluidity, strength and collapsibility. Coated sand particles need to undergo processes such as screening, drying and sieving before being put into use.
[0003] Drying is achieved by heating the inside of the equipment with a heating plate to dry the sand particles. However, since the sand and gravel are piled up together, they will clump together, which not only reduces the drying speed but also easily causes discharge blockage, making subsequent screening difficult. In view of the above reasons, this application proposes a processing device for coated sand particles. Utility Model Content

[0036] The stirring structure 6 includes a stirring rod 601 and a stirring rod 602 for promoting material movement. Gears 603 and 604 for transmission are fixed to the tops of the stirring rods 601 and 602, respectively. Stirring plates 605 for dispersing materials are provided on the exterior of both stirring rods 601 and 602. The stirring plates 605 can disperse stacked or clumped materials, increasing the contact area between the materials and hot air, improving the drying speed, and preventing discharge blockage, ensuring the materials can smoothly enter the screening process. A motor 606 for driving is fixed to the top of the stirring rod 601. A reciprocating screw 607 is provided between the stirring rods 601 and 602. Belt pulley 611 and belt pulley 612 are fixedly mounted on the reciprocating screw 607 and the reciprocating screw 607 respectively. The same belt is mounted on the belt pulley 611 and belt pulley 612. The tops of the reciprocating screw 607, the stirring rod 601 and the stirring rod 602 are movably connected to the top inner wall of the processing box 1. Two flipping plates 609 are movably mounted on the reciprocating screw 607. The same internal thread block 608 is fixedly mounted on the end of the two flipping plates 609 that is close to each other. The internal thread block 608 is movably connected to the reciprocating screw 607. Multiple limiting rods 610 are movably mounted on the internal thread block 608. The top of the limiting rod 610 is fixedly connected to the top inner wall of the processing box 1. The flipping plates 609 can move up and down on the reciprocating screw 607 to realize the flipping function.
[0037] The processing box 1 is equipped with a screening structure 7, which includes a second motor 701 for driving and a screen plate 702 for screening. The inner wall of the processing box 1 is provided with two sliding grooves. Two sliders are fixedly provided on the outside of the screen plate 702. The sliders and the sliding grooves are movably connected. Multiple magnets 703 for adsorbing metal are fixedly provided on the top of the screen plate 702. The magnets 703 can adsorb metal in the material to prevent defects such as sand holes and air holes. The output shaft of the second motor 701 extends to the processing box 1. Two push rods 706 are fixedly provided on the output shaft of the second motor 701. Multiple springs 704 are fixedly provided on the bottom of the screen plate 702. A horizontal plate 705 is fixedly provided on the bottom of the springs 704. The horizontal plate 705 is fixedly connected to the inner wall of the processing box 1.
[0038] In this embodiment, sand is first introduced into the processing box 1, then the heating plate and motor 606 are started. Motor 606 drives stirring rod 601 and gear 603. Gear 603 and stirring rod 601 then drive gear 604 and pulley 611, respectively. Gear 604 and pulley 611 then drive stirring rod 602 and pulley 612, respectively. Pulley 612 then drives reciprocating screw 607. The two stirring rods simultaneously drive multiple stirring plates 605. The stirring plates 605 stir the material in the feed hopper 4. The reciprocating screw 607 moves up and down to agitate the material, thus increasing the amount of material to be dried. The increased contact area with hot air improves the drying speed of the material. After the material is dried, motor 701 is started and solenoid valve 5 is opened. Motor 701 drives two push rods 706, which press the screen plate 702. The screen plate 702 then presses the spring 704 at the bottom. When the push rods 706 separate from the screen plate 702, the spring 704 pushes the screen plate 702 upward, causing the screen plate 702 to vibrate. The material falls on the top of the screen plate 702, and the vibration generated can achieve screening of the material. During screening, magnet 703 can adsorb metal impurities in the material, which can effectively prevent metal impurities from causing defects such as sand holes and air holes on the surface of castings.
[0039] The above specific embodiments are merely several optional embodiments of this utility model.
