Description

Technical Field

[0001] This utility model relates to sewage treatment equipment, and more particularly to a bidirectional sludge removal and rotating brush device for a bar screen cleaner. Background Technology

[0002] A bar screen is a solid-liquid separation device that mechanically removes screenings from water. It is mainly used in the pre-treatment stage of water intakes in sewage treatment plants, pumping stations, waterworks, and food processing plants. Its core function is to use a bar screen to intercept and a rake tooth to remove suspended debris, preventing clogging of subsequent treatment equipment. Existing bar screens often have a rotating brush device at the top for cleaning the rake teeth. However, this device typically only has a single unidirectional rotating brush roller, which can only clean one side of the rake teeth, leaving the other side uncleaned. This results in incomplete cleaning and clogging issues with traditional unidirectional rotating brushes.

[0003] Therefore, how to design a bidirectional cleaning brush device for bar screen cleaners to improve cleaning efficiency and reduce maintenance frequency has become a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

The brush roller 8 is rotatably mounted on the telescopic end of the first electric telescopic cylinder 7, and each end of the brush roller 8 is connected to a first electric telescopic cylinder 7. The first electric telescopic cylinder 7 is mounted on the housing 1. In the first rotating brush assembly 3, one end of the brush roller 8 is drivenly connected to a first pulley and a second pulley.

[0037] The reducer 21 drives the brush roller 8 in the first rotating brush assembly 3 to rotate via the first belt ring 22. When the brush roller 8 in the first rotating brush assembly 3 rotates, it drives the first rotating shaft 42 to rotate via the second belt ring 46. When the first rotating shaft 42 rotates, it drives the first gear 44 to rotate. When the first gear 44 rotates, it drives the second gear 45 meshing with it to rotate. When the second gear 45 rotates, it drives the second shaft 43 to rotate. When the second shaft 43 rotates, it drives the brush roller 8 in the second rotating brush assembly 5 to rotate via the third belt ring 47.

[0038] The two gears in the transmission assembly 4 work together to rotate the brush roller 8 in the first rotating brush assembly 3 in the opposite direction to the brush roller 8 in the second rotating brush assembly 5. This bidirectional rotation of the two brush rollers 8 cleans both sides of the rake teeth, effectively improving the cleaning efficiency of the rotating brush and reducing the maintenance frequency of the bar screen.
