Description

Technical Field

[0001] This utility model belongs to the technical field of sewage treatment equipment, and specifically relates to a cleaning device for a rotary bar screen cleaner. Background Technology

[0002] Rotary bar screens are specialized water treatment equipment that can continuously and automatically intercept and remove debris of various shapes from fluids. They can be widely used in urban sewage treatment, tap water industry, and power plant inlets. They can also be used as pre-screening equipment in wastewater treatment processes in industries such as textiles, food processing, papermaking, and leather. They are one of the most advanced solid-liquid separation equipment currently available.

[0003] Currently, in rotary bar screen cleaning machines, the bar chain carries debris trapped on the bar surface from bottom to top to the discharge port. When the bar chain moves from top to bottom, the debris falls off by gravity and is discharged from the discharge port into the conveyor. However, wastewater contains a large amount of flocculent matter and plastic waste, which can become entangled or adhere to the bar chain and become stuck, potentially affecting the normal operation of the equipment. This also presents the problem of difficulty in cleaning the debris adhering to the bar chain.

[0004] Therefore, there is an urgent need for a cleaning device for rotary bar screen cleaners to solve the above problems. Utility Model Content

The cleaning brush on the cleaning plate can clean the surface of the grid chain. Then, the output shaft of the reduction motor is controlled to rotate in reverse, causing the sliding block to move in the opposite direction, and the cleaning brush is used to sweep the surface of the grid chain again. This operation is repeated until the impurities on the grid chain are cleaned off. The cleaned impurities fall onto the filter screen plate in the slag outlet and are collected. After cleaning, the plugs on both sides of the slag outlet are pulled to remove the filter screen plate, clean off the impurities accumulated on the filter screen plate, and after cleaning, the filter screen plate is reinstalled.

[0016] The beneficial effects of this utility model are that the cleaning mechanism uses the repeated movement of the cleaning brush to clean the debris adhering to the grid chain, making cleaning convenient and effectively ensuring the normal operation of the equipment; in addition, the filter screen is easy to disassemble and assemble, making it convenient to collect and clean the impurities, and the operation is convenient.
