Description

Technical Field

[0001] The utility model relates to the technical field of sludge scraping mechanisms, in particular to a center-driven sludge scraping mechanism with an adjustable scraping arm. Background Technique

[0002] In the sewage treatment industry, sedimentation tanks are key components in the treatment process. Their main function is to allow suspended solids, particulate matter, and some organic matter in the sewage to settle to the bottom of the tank by gravity, forming a sludge layer, while the supernatant is discharged through the outlet for further subsequent treatment. However, with the continuous accumulation of sludge, if not cleaned in time, it will not only occupy the effective volume of the sedimentation tank, reducing the treatment efficiency, but may also cause secondary pollution to the water quality. The center-driven sludge scraping mechanism mainly consists of a driving device, a transmission device, a scraping arm, and a scraping plate, etc. Its working principle is that the driving device drives the transmission device to rotate, thereby driving the scraping arm to make a circular motion along the central axis of the sedimentation tank, and the scraping plate moves with the scraping arm to scrape the sludge at the bottom of the tank and push it to the sludge sump or the sludge discharge port.

[0003] However, in practical applications, due to factors such as the irregular shape of the bottom of the sedimentation tank, uneven sludge distribution, and water quality changes, the center-driven sludge scraping mechanism may encounter some problems during operation. For example, if the gap between the scraping plate and the bottom of the tank is too large or too small, it may lead to poor sludge scraping effect or equipment damage; if the movement trajectory of the scraping arm does not match the characteristics of the sludge distribution, it will also affect the sludge scraping efficiency; in addition, over time, the bottom of the tank may change due to wear, deposition, etc., which also requires corresponding adjustment of the scraping arm.
