0.37 - 1.5kw Mechanical Bar Screen / Bar Rack Water Treatment SS Material
High quality mechanical rake bar screen for wastewater treatment
Fine bar screen is one of the important dirt pretreated and blocked equipment in the wastewater treatment. It can be applied for municipal sewage, drainage pumping plant, industrial wastewater.
Structure and Working Principles
This device is provided with several special-shaped teeth which are assembled on the teeth axis based on certain ordering, forming the sealed teeth chain. The lower part is installed in the water inlet. If the chain wheel rotates directionally with even speed, the whole rake chain will move accordingly. Under such circumstances, the solid sundries attached to the tooth will be separated from the liquid and the fluid will flow away through the gap. When the rake chain arrives at its upper end, each group of rakes will carry on self-cleaning by dropping out most of the solid material under gravity and guideline rail, while the rest of the solid will be tidied clean by back running brush. The whole process is carried out continuously and automatically so as to achieve the goal of solid-liquid separation.
