Description

Technical Field

[0001] The utility model relates to the technical field of rotary drum type screen dirt removers, in particular to a rotary drum type screen dirt remover with high separation efficiency. Background Art

[0002] A rotary drum screen scrubber is a device used in water treatment systems, primarily for solid-liquid separation and wastewater treatment. It typically consists of a rotating cylindrical frame with a mesh or filter inside that filters out solid particles from the water and separates them to purify the water. However, long-term use of a rotary drum screen scrubber can cause the screen basket to clog, reducing separation efficiency. Furthermore, the screen basket is fixed and cannot be replaced with different mesh sizes as needed, further reducing separation efficiency.

[0003] A Chinese patent discloses a rotary drum screen cleaner (authorization announcement number CN218653240U). The patented technology mainly includes a screen frame, a lifting bin is provided on the top of the screen frame, and the lifting bin extends to the inner cavity of the screen frame. A discharge port is provided at the end of the bottom of the lifting bin away from the screen frame. A mounting seat is provided at the bottom of the screen frame, and a base is hinged on one side of the bottom of the mounting seat. A mounting bin is provided in the inner cavity of the base, and threaded rods are provided on both sides of the inner cavity of the mounting bin, and one end of the threaded rod extends to the outside of the base.

[0004] However, this patent still has some shortcomings. When the rotary drum screen cleaner is used for treating sewage, long-term use may cause the screen basket to become clogged, reducing the separation efficiency. At the same time, the screen basket is fixed and cannot be replaced with screen baskets of different mesh sizes as needed, which also reduces the separation efficiency. Therefore, those skilled in the art have provided a rotary drum screen cleaner with high separation efficiency to solve the problems raised in the above background technology. Utility Model Content
