Description

Technical Field

[0001] This utility model relates to the technical field of coated sand production equipment, and in particular to a cooling drum used in coated sand production. Background Technology

[0002] Coated sand is a molding material widely used in the foundry industry. It refers to molding sand or core sand with a layer of solid resin on the surface of the sand grains before molding. In its production process, the cooling process is one of the key links to ensure product quality, and cooling rollers are used to cool the material.

[0003] Because the cooling drum causes the internal material to tumble during operation, material accumulation or clumping can easily occur, which reduces the uniformity and efficiency of cooling. In view of the above reasons, this application proposes a cooling drum for the production of coated sand. Utility Model Content

[0006] The stirring structure includes a motor for driving and a rotating rod for mounting. Multiple stirring blades and heat dissipation blades are fixedly provided on the outside of the rotating rod, and a connecting pipe for driving the rotating rod is movably provided at the output end of the motor.

[0007] Optionally, a support platform is fixedly provided at the bottom of the motor, the support platform is fixedly connected to the base, and two fixing plates are movably provided on the outside of the rotating rod.

Two limiting grooves are provided on the inner wall of the connecting pipe, and two limiting blocks are fixedly installed outside the output shaft of the motor. The limiting blocks and the limiting grooves are movably connected.

[0010] Optionally, both the feed inlet and the discharge outlet are provided with sealing covers. The sealing cover of the feed inlet has a round hole, which is movably connected to the connecting pipe. The roller body is provided with multiple heat dissipation holes, and the heat dissipation holes are provided with filters for blocking dust.

[0011] Optionally, the end of the rotating rod near the motor is provided with a rectangular groove, and the end of the connecting pipe away from the motor is provided with a rectangular plate, the rectangular plate and the rectangular groove being compatible.

[0012] Optionally, the front of the base is provided with a cooling structure for absorbing heat. The cooling structure includes a horizontal plate for installation.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects:

[0014] 1.

[0034] Example

[0035] like Figure 1-4 As shown, the present invention proposes a cooling drum for the production of coated sand, including a base 1, a drum body 2 for cooling materials is movably provided above the base 1, a toothed ring 3 for driving the drum body 2 is provided on the surface of the drum body 2, a discharge port 4 and a feed port 5 are respectively provided at both ends of the drum body 2, and a stirring structure 7 for breaking up agglomerated materials is provided on one side of the base 1.

[0036] The stirring structure 7 includes a motor 701 for driving and a rotating rod 702 for mounting. Two fixing plates 705 are movably mounted on the outside of the rotating rod 702. Both fixing plates 705 are fixedly connected to the inner wall of the drum body 2. The fixing plates 705 have circular holes, and bearings are fixedly mounted inside these holes. The inner ring of the bearings is fixedly fitted onto the rotating rod 702. Multiple stirring blades 704 and heat dissipation blades 703 are fixedly mounted on the outside of the rotating rod 702. The airflow generated by the rotation of the heat dissipation blades 703 accelerates the flow of hot air, making it easier for it to move towards the air outlet or opening of the drum and be discharged outside. Combined with the use of heat dissipation holes 8, this enhances the ventilation and heat dissipation effect, ensuring that the coated sand can be cooled quickly and evenly. A support platform 707 is fixedly mounted on the bottom of the motor 701, and the support platform 707 is fixedly connected to the base 1. The output end of the motor 701 is movably connected to a connector that drives the rotating rod 702. The tube 709, and the telescopic connecting tube 709, facilitates the disassembly and installation of the sealing cover. Both the feed inlet 5 and the discharge outlet 4 are equipped with sealing covers. The sealing cover of the feed inlet 5 has a round hole, which is movably connected to the connecting tube 709. The drum body 2 is equipped with multiple heat dissipation holes 8, which allow hot air inside the drum to be discharged. The heat dissipation holes 8 are equipped with a filter screen for blocking dust. A spring 710 is fixedly installed inside the connecting tube 709. The other end of the spring 710 is fixedly connected to the output shaft of the motor 701. The inner wall of the connecting tube 709 is equipped with two limiting grooves. Two limiting blocks 708 are fixedly installed outside the output shaft of the motor 701. The limiting blocks 708 are movably connected to the limiting grooves. The end of the rotating rod 702 near the motor 701 is equipped with a rectangular groove 706. The end of the connecting tube 709 away from the motor 701 is equipped with a rectangular plate 711. The rectangular plate 711 and the rectangular groove 706 are compatible.

[0037] The front of the base 1 is provided with a cooling structure 6 for absorbing heat. The cooling structure 6 includes a horizontal plate 601 for installation. The top of the horizontal plate 601 is provided with a cooling water tank 602 and a water pump 603. The drain end of the water pump 603 is fixedly provided with a cooling water pipe 604. The cooling water pipe 604 is located above the drum body 2. The other end of the cooling water pipe 604 is fixedly connected to the top of the cooling water tank 602. The external cooling structure 6 will not occupy the internal space of the drum, will not affect the arrangement of the mixing structure 7 and the normal flow of materials, and will help ensure the uniform mixing and cooling effect of the coated sand in the drum.

[0038] In this embodiment, the meshing of the gear ring 3 and the drive device in the base 1 enables the drum body 2 to rotate. Before use, coolant is injected into the cooling water tank 602. Then, the material is introduced into the drum body 2 through the feed inlet 5. After the material is fed, one end of the connecting pipe 709 is inserted through the sealing cover on the feed inlet 5 and extends into the drum body 2, allowing the rectangular plate 711 to be inserted into the rectangular groove 706. Then, the water pump 603, motor 701, and equipment body are started to perform cooling operations. The drum body 2 drives the internal material to rotate, and the water pump 603 introduces the coolant in the cooling water tank 602 into the cooling water pipe 604. The cooling water pipe 604 can remove the heat dissipated inside the drum body 2. The motor 701 drives the material to rotate. The connecting pipe 709 drives the rotating rod 702, which in turn drives the stirring blades 704 and the heat dissipation blades 703. The stirring blades 704 cause the material to continuously change position within the cooling drum, preventing local overheating or overcooling and improving the uniformity of cooling. The tumbling action of the stirring blades 704 can break up the agglomeration between particles, keeping the coated sand in a loose state and preventing the formation of clumps, which is beneficial for subsequent processing and use. The airflow generated by the rotation of the heat dissipation blades 703 accelerates the flow of hot air, making it easier for it to move towards the air outlet or opening of the drum and be discharged outside the drum. Combined with the use of the heat dissipation holes 8, it can enhance the ventilation and heat dissipation effect, ensuring that the coated sand can be cooled quickly and evenly.

[0039] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
