Description
Technical field
The present invention relates to the free drop filter of a kind of gravity type, the free drop filter of this gravity type is suitable for sewage treatment plant's sewage water depth-type filtration and handles, and the fresh water (FW) reuse is filtered, and middle water reuse filtration, belongs to the sewage water filtration process field.
Background technology
The at present existing disk type filtering equipment that is used for the sewage water filtration processing is divided into two kinds of primary structures.The disk type filtering equipment of two kinds of structures all is middle rotatable rotary drums that a hollow is arranged; Have a plurality of openings on the rotary drum; Be radial mutual connection by N filtration fan on the opening and form a circular filtering chamber, N circular filtering chamber being distributed on the rotary drum along the rotary drum parallel longitudinal.First kind of structure will be that the former water that needs to handle gets into the filtering chamber that is made up of filter membrane via middle rotary drum through the opening on the rotary drum, and former then water flows out through filter membrane, and the particle after the filtration is stayed the inside of filtering chamber.When filter membrane can not play effective filtration, backwashing system started, and rotary drum begins rotation, will stay the inner particle of filtering chamber through the outside nozzle of installing of filtering chamber and pour in the inner feeder.Second kind of structure is to make the former water that needs to handle flow in the filtering ponds earlier; Former then water, gets in the rotary drum by the outside chamber interior that gets into of filtering chamber through filter membrane then, and the particle after the filtration is stayed the filtering chamber outside; When filter membrane can not play effective filtration; The back suction desorption system starts, and rotary drum begins rotation, siphons away at the particle that will stay on the filter membrane through the outside sucker of installing of filtering chamber.
More than the disk type filtering equipment of two kinds of structures, no matter be to adopt the rinsed filter membrane or suck filter membrane with sucker, the rotary drum in the middle of all need rotating could realize cleaning the function of filter membrane.Therefore there is following weak point:
1, because the rotary drum of a hollow is arranged, in order to increase effective filtration area, it is big to cause filtering the fan diameter, and the disk type filtering equipment volume is big, and floor space is big.
2, because rotary drum needs rotation, cause the requirement of filter fan support member hardness and sealing highly, make the support member complex design, materials are many, the cost height.
3, since backwash or back suction desorption system need rotate rotary drum could the effective cleaning filter membrane, the power of motor that causes rotating rotary drum is big, operating cost is high.
Summary of the invention
The objective of the invention is to propose the free drop filter of a kind of novel gravity type, existing disk type filtering equipment structure is improved, so that the disk type filtering equipment structure is compact more; Floor space is littler; Processing technology is simpler, and cost is lower, and operating cost is lower.
The free drop filter of the gravity type that is used for sewage water filtration that the present invention proposes comprises transmission mechanism, water inlet main line, water inlet branch line, Suction cup assembly, filter element, filter membrane component, back suction suction main line, blowdown main line.Have water main inlet port at the top of free drop filter one side of gravity type and connect the water inlet main line; The water inlet main line is at the top of the free drop filter of gravity type; Have the branch's water inlet that equates with filter element quantity on the water inlet main line; The branch water inlet connects the water inlet branch line, and the water inlet branch line is connected with the filter element top through snap joint and communicates.Filter element is radial by N filter membrane component and connects the filter element of forming a circular hollow mutually through the fan frame.N circular filter element is through the connector of home position and being distributed in the free drop filter of gravity type of filtration support unit vertical parallel.A back suction that links to each other in transmission mechanism is inhaled main line and is run through the connector between each filter element; Each filter element is connected; Back suction has the back suction suction inlet that equates with filter element quantity on inhaling and being responsible for, and the back suction suction inlet is mounted on the Suction cup assembly in the hollow filter element.Suction cup assembly is made up of H type tube connector and sucker, and Suction cup assembly is inhaled main line through back suction and linked to each other with the back suction sucking pump of back suction sucking-off water pipe in the free drop filter of gravity type side.There is a blowdown main line below of the free drop filter of gravity type; The blowdown main line links to each other through the back suction sucking pump of the free drop filter of blowdown outlet pipe and gravity type side; Have the branch's sewage draining exit that equates with filter element quantity on the blowdown main line, branch's sewage draining exit through with the water inlet branch line on isostructural snap joint be connected in filter element bottom and communicate.Bottom crossing the free drop filter of gravity type and water main inlet port homonymy or corresponding opposite side has clear water output.
Above-mentioned filter membrane component is worked out by chemical fibre or wire, becomes a fan type.Processing of fan frame by engineering plastics or stainless steel, the fan frame is made up of two brace summers and an outer plate, and filter membrane component is embedded on the fan frame, and each filter membrane component connects the formed hollow circular filter element in back through the fan frame, and inboard one side is that smooth nothing rises and falls.
Above-mentioned Suction cup assembly is connected through H type tube connector, and each Suction cup assembly is made up of two suckers, and each sucker is provided with suction inlet, and soft fiber small brushes is arranged around the suction inlet.
The connector of above-mentioned filter element is the cylinder of a hollow, and diameter is inhaled main line greater than back suction, and cylindrical two ends are the flange connecting interface.
The free drop filter of gravity type that the present invention proposes; Advantage is; Former water flows into circular filter element inside through the water inlet main line at the free drop filter of gravity type top through the water inlet branch line; Former then water flows out through filter membrane, and filter element can not receive the into influence of water water impact.The interior circular diameter that filter element in the existing disk type filtering equipment does not participate in filtering is 500～800mm; The interior circular diameter that the filter element of the free drop filter of gravity type that the present invention proposes does not participate in filtering is 150～280mm; Catch up with and state two kinds of existing disk type filtering equipments and compare; The filter element of equivalent diameter is compared with the existing filter plant of above-mentioned first kind of structure, and effective filtration area has improved 80～120%; Compare with the existing filter plant of second kind of structure, effective filtration area has improved 10～20%.Filter element need not rotation, has reduced the requirement to fan frame intensity, and the fan frame is lighter and handier, becomes the product cost lower, and processing technology is simpler.Transmission mechanism drives back suction and inhales the main line rotation, and used power of motor is less than existing filter plant.With the equipment of performance, the free drop filter of gravity type that the present invention proposes, volume is littler, and production cost and operating cost are lower.
