Abstract
An internally fed drum filter for treating waste water, includes an inlet distribution arrangement for distributing waste water entering the drum filter via an inlet duct, characterized in that the inlet distribution arrangement includes an adjustable flow deflection member arranged near the outflow opening of the inlet duct, downstream thereof, for adjusting the flow characteristics of waste water entering the drum filter via the inlet duct.
Claims17
An internally fed drum filter for treating waste water, comprising:
- an inlet distribution arrangement for distributing waste water entering the drum filter via an inlet duct, the inlet distribution arrangement comprising a flow deflection member arranged near an outflow opening of the inlet duct, downstream thereof, for adjusting the flow characteristics of waste water entering the drum filter via the inlet duct,
- wherein the flow deflection member is connected to an underside of the inlet duct by a hinge that allows rotation of the flow deflection member from and towards the outflow opening of the inlet duct, the flow deflection member having a flow deflection surface for deflecting an incoming flow from the inlet, the flow deflection surface extending upwardly from below a lower edge of the outflow opening of the inlet duct, and
- wherein the flow deflection member is upwardly inclined, and wherein an angle of the upwardly inclined flow deflection member with respect to a centre line of the inlet duct is adjustable within a range of 5°-50° by rotation of the flow deflection member.
An internally fed drum filter for treating waste water, comprising:
- an inlet duct;
- an outflow opening of the inlet duct;
- an upwardly inclined flow deflection member arranged near the outflow opening, for adjusting the flow characteristics of waste water entering the drum filter via the inlet duct, an angle of the upwardly inclined flow deflection member with respect to a centre line of the inlet duct is adjustable within a range of 5°-50° by rotation of the flow deflection member;
- a hinge that allows rotation of the upwardly inclined flow deflection member, the hinge connecting the flow deflection member to an underside of the inlet duct so as to allow rotation of the flow deflection member from and towards the outflow opening of the inlet duct, the flow deflection member having a flow deflection surface for deflecting an incoming flow from the inlet, the flow deflection surface extending upwardly from below a lower edge of the outflow opening of the inlet duct;
- and
- an activator connected to the upwardly inclined flow deflection member, the activator comprising a rod that projects through a separation wall.
