Description

Technical Field

[0001] The utility model relates to the technical field of vibrating screens, and more specifically to a vibrating screen filter with an anti-blocking structure. Background Art

[0002] The vibrating screen works by using the reciprocating vibration generated by the vibrator excitation. The upper rotating weight of the vibrator causes the screen surface to produce a plane gyratory vibration, while the lower rotating weight causes the screen surface to produce a conical gyratory vibration. The combined effect causes the screen surface to produce a complex gyratory vibration. Its vibration trajectory is a complex spatial curve. The curve is projected as a circle on the horizontal plane and an ellipse on the vertical plane. There is a screen on the vibrating screen, and the screen is used to screen the material. However, as the material screening proceeds, some of the screen holes on the screen are easily blocked by the material, which affects the screening efficiency. At the same time, the blocked material in the screen holes on the screen is not easy to clean, which seriously affects the normal operation of the vibrating screen. For this reason, we propose a vibrating screen filter with an anti-blocking structure. Utility Model Content
