Abstract

The utility model relates to a filter containing bulk materials, comprising an outer shell (9), filtering materials, a supporting rack (10), a water inlet pipe (4), a water outlet pipe (5), a backwashing water inlet pipe (6) and a sewage pipe. The filtering materials (3) which form a blanket shape are attached on the supporting rack (10), dividing the inner cavity of the filter into a turbid water cavity (1) and a clear water cavity (2). The water outlet of the water inlet pipe (4) is arranged toward the turbid water cavity (1); the water outlet pipe (5) and the backwashing water inlet pipe (6) are arranged on the wall of the clear water cavity; the lower part of the turbid water cavity is provided with the sewage pipe (7). The utility model has the advantages of big filterability per unit ground occupation area, small ground occupation area, and good filtration effect.

Description

Filter

The utility model relates to a kind of water treatment purifier, particularly a kind of filter that contains bulk material.

In water treatment field, the conventional water treatment process of extensive use both at home and abroad is at present: add coagulation (or flocculation) agent in pending water, enter the sedimentation basin precipitation, filtering than granule of failing to remove in sedimentation basin through the filter tank again removed, and enters then in clear water reserviors or following one water processing establishment.

Existing filter tank generally is sand filter or multilayer filter material filter pool.Sand filter is to form certain grating with the sand of different-grain diameter, and the water of post precipitation is through the sand filtering material in the filter tank.Sand filtering material is held back the impurity particle in the adsorbed water, and water is separated with impurity; The multilayer filter material filter pool is the filtrate layering laying up and down of adopting different specific weight.Though contain dirty ability enhancing is arranged slightly, it is poor to have improved filtering cloth head, has caused the certain energy waste.Though it is good to lay the filter effect of fiber filtering at the bottom of the pond, its blowdown problem can not solve well.

Above-mentioned filter floor space is big, and the water treatment amount is little, filtrate contain dirty ability and filth-discharging effect poor, and often cause filtrate to be penetrated, make the filtered water short circuit pass filter material layer, cause the filter tank to lose efficacy.

The utility model purpose is to overcome above-mentioned shortcoming of the prior art and a kind of water filter is provided, and improves the filter capacity of unit occupied area, reduces floor space, improves filter capacity and effect.

The purpose of this utility model is achieved by the following technical solution: filter comprises shell (9), filtrate, bracing frame (10), water inlet pipe (4), outlet pipe (5), backwash water inlet pipe (6), blow-off pipe (7) in forming.The filtrate (3) that is the blanket shape is divided into muddy water chamber (1), clear water chamber (2) attached on the bracing frame (10) with the filter inner chamber, and the delivery port of water inlet pipe (4) is opened to muddy water chamber (1).When pending muddy water when water inlet pipe (4) enters the muddy water chamber, because the effect of pressure reduction will see through and filter blanket (3), filter blanket (3) is held back dirt particle, clear water enters in the clear water chamber (2), becomes filtered water, is flowed out by the outlet pipe (5) that is located on the wall of clear water chamber; Backwash tube (6) inlet also is located on the wall of clear water chamber, during backwash, clear water with certain pressure enters clear water chamber (2) by backwash tube (6), the reverse filter blanket that passes, the dirt particle of filter in the blanket poured the muddy water chamber, and by the blow-off pipe (7) of bottom, muddy water chamber with backwash mudflow discharge filter.

The utlity model has that the unit occupied area filter capacity is big, floor space is little, the advantage of good filtration effect.

The schematic diagram of accompanying drawing for using embodiment of the utility model to filter.

Below in conjunction with accompanying drawing, further specify the utility model by embodiment.

During forming, filter comprises shell (9), filter blanket (3), bracing frame (10), water inlet pipe (4), outlet pipe (5), backwash water inlet pipe (6), blow-off pipe (7), the additional water pipe (8) of flushing.Bracing frame (10) bottom and filter bottom are joined, filter blanket (3) is served as reasons and is knitted (volumes) and make the tapetum fibrosum of substrate with fiber bond one-tenth, attached to being on 60 °-90 ° the bracing frame (10) with filter bottom, the filter blanket is divided into muddy water chamber (1), clear water chamber (2) of alternately arranging mutually with the filter inner chamber, and the delivery port of water inlet pipe (4) is opened to muddy water chamber (1).When pending muddy water when water inlet pipe (4) enters the muddy water chamber, because the effect of pressure reduction will see through and filter blanket (3), filter blanket (3) is held back dirt particle, clear water enters in the clear water chamber (2), becomes filtered water, is flowed out by the outlet pipe that is located at clear water chamber lower wall (5); Backwash tube (6) inlet also is located at clear water chamber lower wall, during backwash, clear water with certain pressure enters clear water chamber (2) by backwash tube (6), the reverse filter blanket that passes, at this moment, place the additional water pipe (8) of flushing on filter blanket (3) top also to emit clear water, the dirt particle in the filter blanket is poured the muddy water chamber, and by the blow-off pipe (7) of bottom with backwash mudflow discharge filter.
