Grills Type Mechanical Coarse Screen Water Treatment For Sludge Treatment

Mechanical bar screen for sludge treatment is a kind of advanced solid-liquid separation device in water treatment, which can continuously and automatically remove debris from wastewater for sewage pretreatment. It is mainly used in municipal sewage treatment plants, residential quarters sewage pretreatment devices, municipal sewage pumping stations, waterworks and power plants, also it can widely be applied to water treatment projects of various industries, such as textile, printing and dyeing, food, fishery, paper, wine, butchery, curriery etc.

Main Features Of Mechanical Bar Screen For Sludge Treatment

1. The driving unit is directly driven by cycloidal gear reducer or helical gear reducer which shows the nature of working stability, low noise, big load capability and high efficiency in conveying.
2. Simple structure with compact size, easy to install and move. Device can self-clean up while working, easy to maintain.
3. Easy to operate, can be controlled directly on the spot or remote.
4. Include overload protection device, machine will shut down automatically when malfunction happens to avoid damage.
5. When the device width exceeds 1500mm, will be made into parallel machine to ensure the overall strength.

Bar screen mainly composed of driven device,rake tooth facility ,Flush facility etc, which is assembled to be a group of rotary bar screen chain by a unique rake tooth, driven by Motor reducer, the rake tooth chain going Rotary motion as reverse flow.

When the rake tooth chain operate to upside of equipment, due to the guiding of Geneva wheel and curve, which produce the relative self-cleaning motion between each group rake tooth, most of the solid drop down by gravity. Another parts clean up the sundries sticking in the rake tooth by sweeper ‘s Reverse movement.

Rake tooth chain similar to grilling by water flow direction, the rake tooth clearance which assembled in rake tooth chain shaft can be chose according to usage condition; Which can guarantee water flow pass by smoothly after the rake tooth separate the suspended solid in the fluid. the whole process can be continuous and intermittent.
