The rotary rake grille cleaning machine is a cutting-edge water treatment marvel, engineered to continuously and automatically intercept and eliminate various debris within fluids. It's widely applicable in urban sewage treatment and stands as a pinnacle of solid-liquid screening technology in China. This advanced device is pivotal in wastewater treatment processes across diverse industries such as textiles, food processing, papermaking, and leather, in addition to bolstering the water supply sector and power plant intakes.
Working Principle
The ingenious rotary grid cleaning machine, featuring a unique rake tooth factory assembly, forms a rotating grid chain. Powered by a motor reducer, this rake chain expertly rotates against the water flow, ensuring optimal performance.
As the rake chain ascends to the equipment's upper section, guided by a groove wheel and curved rail, each set of rake teeth engages in relative self-cleaning motion. Gravity assists in dislodging most solid materials, while any residual debris is removed through the reverse movement of the cleaner, ensuring impeccable maintenance of the rake teeth.
Aligning with the water flow, the rake chain mimics a grille, with the spacing between the rake teeth on the chain shaft adjustable to meet usage conditions. As the rake teeth effectively segregate solid suspended solids in the fluid, it guarantees a smooth flow of water, with operations capable of being continuous or intermittent, depending on requirements.
The equipment's standout feature is its high automation level, exceptional separation efficiency, minimal power consumption, silent operation, and robust corrosion resistance. It assures unmonitored, continuous, and stable performance, complete with overload safety protection to prevent operation under excessive loads. The device can tailor its operating intervals to user specifications, allowing periodic operation; it can be auto-controlled based on the liquid level difference pre and post grille, and includes a manual control function for straightforward maintenance. Users enjoy the flexibility to adapt to varying job demands.
Thanks to the device's thoughtfully engineered structural design, it boasts a formidable self-cleaning capacity during operation, mitigating any risk of blockage and significantly reducing daily maintenance efforts.
