Product Overview
Description
ROTARY SCREEN is used for solid/liquid separation for high flow rate and combine two operations: filtration and compacting. They feature a screen basket, perforated pores or wedge wire, that act as a filter and rotating with the transport screw, followed by the transportation that ends with a compacting modulus. Screenings are conveyed by a shaft screw until the compacting/dewatering section where both volume and weight are reduced (up to 40%).
The rotary screen is installed at the inlet of pump station or water treatment system. It is composed of pedestal, specific plough shaped tines,rake plate, elevator chain and motor reducer units etc. It is assembled into different spacing according to different flow rate.The rake plate ,which is fixed in the elevator chain,starts clockwise movement under the drive of the driving device, hooking residue from down to up together with the elevator chain. Under the effect of steering guide and guiding wheel, residue gets discharged by gravity while the rake plate reached the top of screen. The rake tines moved to the bottom of the equipment and starts to work for another round,residue moves continuously.
*The different Rotary Drum Fine Screen has Perforated Plate or Wedge-wire models, from 0.5mm-12mm, more models are available to make custom-design equipment, contact our reps. for more details.
Advantages ■ Low headloss – High separation efficiency Due to the drum's shape and 35° installation the screen area is much larger than that of a vertical or steeply inclined screen, which results in a low headloss, high separation efficiency and maximum throughput. ■ No by-passing The entire flow enters the screen drum through its open front end and can only leave the drum through its screen area. This prevents plant overflow and guarantees that the screenings are always retained within the screen drum. ■ Several functions combined in one system Perform the functions of screenings removal, transport, washing, dewatering and compaction in a single space saving unit. ■ Retrofitting The design of the RO Screens allows for later modification so that the systems can be adapted to changing requirements. The heating and/or integrated screenings washing can be retrofitted. The bar spacing can also be reduced to meet more stringent requirements. ■ Low maintenance No lubrication. Regular checking and visual inspection are sufficient. |
