Description

Technical Field

[0001] The utility model relates to the technical field of vibrating screens, and more specifically to a screening component of a vibrating screen. Background Art

[0002] Vibrating screen is a filtering mechanical separation equipment used for solid phase processing. It is mainly composed of screen and vibrator. The coarseness of the screen is expressed in mesh. Generally, the screen below 50 mesh is coarse screen, and the screen above 80 mesh is fine screen. The vibrator is an eccentric wheel, which rotates under the drive of the motor to make the screen frame vibrate. Due to the vibration of the screen frame, the coarser solid particles on the screen surface remain on the screen surface and are discharged from one end along the inclined surface, while the finer solid phase particles fall through the screen holes, thus achieving screening.

[0003] After searching, the utility model patent with announcement number CN215844077U discloses a vibrating screening mechanism of a vibrating screen, including a screening plate, a first bracket, a rotating shaft, a turntable and a counterweight block, the first bracket is fixedly mounted on the screening plate, the rotating shaft is rotatably mounted on the first bracket, a motor is arranged on the first bracket, the output end of the motor is concentrically connected with the rotating shaft, the turntable is fixedly mounted on the rotating shaft, and the counterweight block is fixedly mounted on the turntable; it also includes a second bracket, a third bracket, a fine screen plate, multiple groups of buffer devices, a fourth bracket, a fifth bracket, a sixth bracket, a bearing base, a transmission motor, a motor base and a belt, the screening plate is fixedly mounted on the top of the third bracket through the second bracket, the fine screen plate is mounted on the third bracket, the third bracket is fixedly mounted on the fifth bracket through multiple groups of buffer devices, and the sixth bracket is fixedly mounted on the side wall of the first bracket.

[0004] However, the above patents still have the following shortcomings: the material on the screening plate and the fine screen plate moves down quickly, which is not convenient for ensuring that the material is completely screened, affecting the quality of the material screening; it is also not convenient to replace screens with different screening inner diameters. For this reason, we propose a screening assembly for a vibrating screen. Utility Model Content
