[0014] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0015] In the description of the embodiments of this utility model, it should be noted that if terms such as "upper," "lower," "inner," or "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, they are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the utility model. Furthermore, if terms such as "first" or "second" appear in the description of this utility model, they are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0016] In the description of the embodiments of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] As shown in the attached drawings, this utility model includes a roller 30, a roller support 31, a roller drive motor 32, a spray pipe 33, and a water tank 34. The roller drive motor 32 is mounted on the roller support 31 and drives the roller 30 to roll on the roller support 31. Multiple sets of lifting plates 40 are provided inside the roller 30. The water tank 34 is located below the roller 30. The spray pipe 33 is located above one side of the roller 30. The spray pipe 33 is connected to the water tank 34 through a pump. A flow equalization plate 35 is provided at the bottom of the spray pipe 33. A gap is provided between the flow equalization plate 35 and the rolling surface of the roller 30.

[0018] The molding sand enters the drum 30 from the feed end. When the drum 30 rotates, the lifting plate 40 turns the sand particles and conveys them to the discharge end. The spray pipe 33 sprays the water in the water tank 34 evenly onto the flow equalization plate 35. The water flows down from the flow equalization plate 35 to form a water curtain that evenly covers the surface of the drum 30, thereby cooling it and removing the heat from the sand particles inside the drum 30.

[0019] The flow equalization plate 35 forms a slide, which allows water to be spread smoothly onto the roller 30, preventing water from the spray pipe 33 from directly impacting the roller 30 and causing water splashing.

[0020] Preferably, both ends of the drum 30 are conical cylinders, and a set of spiral guide vanes 38 are provided inside the conical cylinder at the discharge end. The spiral guide vanes 38 facilitate the output of sand particles inside the drum 30.

[0021] Furthermore, the drum support 31 is provided with a support roller, the drum 30 is provided with an annular guide rail that cooperates with the support roller, the drum 30 is provided with a toothed disc, and the drum drive motor 32 is provided with a drive gear that cooperates with the toothed disc; the lifting plate 40 is inclined, and multiple sets of lifting plates 40 are spirally distributed inside the drum 30.

[0022] There are two annular guide rails, located at both ends of the drum 30. The flow equalization plate 35 is located between the two annular guide rails. In this design, a baffle plate is provided on the inner side of the annular guide rails to effectively prevent water stains on the surface of the drum 30 from overflowing from the annular guide rails to the outside. The lifting plates 40 are inclined, and multiple sets of lifting plates 40 are spirally distributed inside the drum 30. When the sand particles flow in the inner drum 30, they are sequentially output to the discharge end by the lifting plates 40.

[0023] Furthermore, the spray pipe 33 is mounted on the roller support 31 via a support frame. The bottom of the spray pipe 33 has multiple water outlets along its length. The flow equalization plate 35 is located on one side of the water outlets and can be adjusted and mounted on the spray pipe 33.

[0024] Furthermore, the flow equalization plate 35 is provided with connecting sleeves 36 at both ends, and can be rotatably installed on the spray pipe 33 through the connecting sleeves 36. A pair of flow equalization plate adjustment support rods 37 are provided on the support frame.

[0025] The tilt angle of the flow equalization plate 35 is adjusted by adjusting the support rod 37 of the flow equalization plate, and the gap between the flow equalization plate 35 and the roller 30 is controlled.

[0026] A pair of flow equalization plate adjustment support rods 37 are rotatably mounted on the support frame. The rear side of the flow equalization plate 35 is provided with a set of positioning grooves that cooperate with the flow equalization plate adjustment support rods 37. The tilt angle of the flow equalization plate 35 can be controlled by adjusting the position of the flow equalization plate adjustment support rods 37 in different positioning grooves.
