trash rake-bar screen for sewage treatment
Mainly used in entrance channel or well for pump station to blockade and catch the drifts on the water to ensure normal operation of water pump.Normally used as intermediate or fine bar racks,suitble for water area with depth no more than 2 meters.
1.Simple construction,reliable operation.
2.Except the parts of bars and rake tooth under the water,all the parts of the machine are above water surface,so the whole machine has a long service life for less corrosion and convenent maintenance.
3.Have over loading protection set,ensure the grid cleaner safe and reliable.
4.The driving device adopts a new-type turning speed reducer fixed on the shaft,no need for couplings and alignment,easy to install and compact.
Structure and working principal:
Model series cleaner is ccomposed of motor,speed reducer,the gear,upper and lower chain wheels and chains separately mounted at two sides,forming a closed loop chain while the roller on the other joint is in the Viron guide rail which is parallel to the grate.The toothed raker is fixed onto the base oine of triangle rod frame.When the chain is driven by the driving mechanism at the top(the chain turns clockwise),the raker frame will do plan movement under the restriction of chain and guide rail.One cycle of operation includes closing the raker and taking residual underwater,moving upward and conciying
residual,residual discharge and opening the rake and changing the position.In this case,when the toothed raker moves upward and touches the shinning plate at the top and under the action of relative movement,the residual
will be removed to the residual barrel through guide plate.
