Description

Technical Field

[0001] The utility model relates to the technical field of screening, in particular to a raw material screening device. Background Art

[0002] Screening is the process of separating bulk materials into different particle sizes through one or more screens. Screening equipment uses the relative motion between the bulk material and the screen surface to force some particles through the sieve holes, thereby separating materials such as sand, gravel, and crushed stone into different sizes. The screening process is generally continuous. After the raw material is fed to the screening machine (referred to as the sieve), material smaller than the mesh size passes through the sieve holes and is called the undersize product. Material larger than the mesh size is continuously discharged from the sieve surface and is called the oversize product.

[0003] Existing, such as Chinese patent publication number: CN220861984U The utility model discloses a double screening device for raw materials, which belongs to the technical field of filling furnace charges. It is aimed at the need to screen the raw materials for filling furnace charges after the raw materials are crushed. During the screening process, although a vibrating screen can be used for screening, double screening cannot be performed, and the screening holes cannot be automatically cleaned during the screening process, which reduces the practicality. The utility model includes a screening box, and a screening plate 1 and a screening plate 2 are slidingly connected between the inner side walls of the screening box. The screening plate 1 is located directly above the screening plate 2, and the screening plate 1 and the screening plate 2 are arranged parallel to each other; the utility model can quickly perform double screening on the raw materials through the cooperation of the screening box, the screening plate 1, the screening plate 2, the screening holes, the connecting plate, the guide plate, the mounting plate, the driving motor, the cam, the arc plate, and the reset spring. During the screening process, the raw materials are automatically moved back and forth for shaking screening, thereby further improving the screening effect.

[0004] Although the above patent can quickly perform double screening on raw materials and automatically perform reciprocating shaking screening on the raw materials during the screening process, which further improves the screening effect, the screening mesh in the patent is fixedly installed inside the screening box. When the screening mesh needs to be replaced, it is not convenient to disassemble it. Therefore, a raw material screening device is needed to solve the above problem. Utility Model Content
