Abstract
A membrane filtration apparatus includes a frame, in which a plurality of membrane members, an aeration device, a cleaning device, and a jet device are provided. The cleaning device includes a rail mounted on the frame; an up frame engaging the rail to be moved in the rail, a plurality of cleaning wires respectively having an end connected to the up frame and respectively passing through a space between each two of the neighboring membrane members; and a low frame connected to opposite ends of the cleaning wires. A motor is provided to move the up frame so that the cleaning wires are reciprocating in the space to scratch the sludge off the membrane members.
Claims9
A cleaning device of a membrane filtration apparatus, wherein the membrane filtration apparatus includes a frame and a plurality of membrane members mounted in the frame in parallel, and each of the membrane members includes at least one membrane, the cleaning device comprising:
- a rail mounted on the frame;
- an up frame engaging the rail, and the up frame being driven to be moved on the rail;
- a plurality of cleaning wires, each respectively having an end connected to the up frame, and each respectively passing through a space between each two of the membrane members;
- a low frame connected to opposite ends of the cleaning wires;
- and
- an aeration device mounted on the frame, wherein the aeration device has a plurality of apertures to provide air bubbles;
- wherein the up frame is vertically above the membrane members, and the low frame and the aeration device are vertically under the membrane members;
- wherein the rail is parallel to the membrane members, and the up frame is perpendicular to the rail, so that the cleaning wires reciprocate in the spaces between the membrane members in a horizontal direction when the up frame is reciprocating on the rail;
- wherein the low frame is between the membrane members and the aeration device, and the low frame and the cleaning wires are agitated by the air bubbles of the aeration device.
