Description

Technical Field

[0001] The utility model belongs to the technical field of screening devices, and in particular relates to a rotary vibration screen cleaning device. Background Art

[0002] The rotary vibrating screen is a high-precision fine powder screening machine with low noise, high efficiency, and quick screen change in 3-5 minutes. It has a fully enclosed structure and is suitable for screening and filtering of materials such as particles, powders, and mucus. The rotary vibrating screen uses an upright motor as the excitation source. Eccentric weights are installed on the upper and lower ends of the motor to convert the motor's rotational motion into horizontal, vertical, and inclined three-dimensional motion, and then transmit this motion to the screen surface. Since the objects being screened are large and easy to stick together, the mesh is prone to clogging after long-term use. A device that can clean the screen on both sides is now proposed.
