Abstract
The utility model belongs to a filtering device of water and water solution, a no-backwash fiber filtering machine, comprising a container, with in and out water pipes arranged inside the container, upper and lower otter boards and a fiber filter layer which consists of a plurality of fiber bundles, with the fiber bundles top connected with the upper otter board fixed inside the container and the bottom connected with the lower otter board, which is characterized that a dredging pipe is arranged in the fiber filter layer, a separating board is arranged in the lower part of the lower otter board, an impurity deposition chamber is arranged under the separating board, and a draining pipe is arranged under the container which is connected with the impurity deposition chamber. A net barrel supporting the fiber layer is arranged inside the container, the lower otter board connected with the net barrel. The space between the net barrel and an inner wall of the container is an impurity deposition way, which is connected with the impurity deposition chamber. A top end of the dredging pipe is connected with a porous sprinkler, with the characteristics of simple structure, low cost, small filter resistance, strong interception capability, long service life and wide application scope.
Description
Technical field
A kind of no backwash fabric filter belongs to the filter of water, the aqueous solution.
Background technology
Existing a kind of fabric filter is provided with inlet tube and outlet tube by container in container, fibrous filter layer also is provided with back purge system at the container upper and lower end and forms.The weak point of this fabric filter is, complex structure, and the manufacturing cost height, developing result is poor, and filtration resistance is big, and service life is low.This fabric filter only is applicable to better water treatment, is not suitable for sewage disposal.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of impurity settling chamber that has, and the mediation water pipe is set in fibrous filter layer, and simple in structure, cost is low, and filtration resistance is little, and retaining power is strong, long service life, no backwash fabric filter applied widely.
The technical scheme that solves its technical problem employing is: a kind of no backwash fabric filter, it comprises container, inlet tube and outlet tube is set in container, upper and lower web plate and fibrous filter layer, fibrous filter layer is made up of some fibre bundles, the fibre bundle upper end last web plate interior with being fixed on container is connected, its lower end is connected with following web plate, be characterized in: the mediation water pipe is set in fibrous filter layer, below following web plate, dividing plate is set, the below of dividing plate is the impurity settling chamber, is provided with the blow-off pipe that communicates with the impurity settling chamber in the container lower end.The fibrolaminar net bucket of supporting is set in container, and following web plate is connected with the net bucket, and the net bucket is an impurity sedimentation passage with the space of container inner wall, and this impurity sedimentation passage is connected with the impurity settling chamber.The mediation water pipe places fibrous filter layer, and the head end of mediation water pipe is connected with porous nozzle.
No backwash fabric filter of the present utility model is compared with existing fabric filter, because the utility model is in the fibrous filter layer in container the mediation water pipe to be set, below fibrous filter layer, be provided with the structure of impurity settling chamber, do not need back purge system is set in addition, place minute impurities particle deposition that the water pressure of the mediation water pipe of fibrous filter layer just can directly hold back fibrous filter layer in the impurity settling chamber and discharge from blow-off pipe.Also owing in container, be provided with the fibrolaminar net bucket of supporting, the net bucket is an impurity sedimentation passage with the space of container inner wall, this impurity sedimentation passage is connected with the impurity settling chamber, enter the settling chamber along the sedimentation passage on the one hand impurity necessary path is provided, on the other hand fibrage is played supporting role, prevent fibrage deformation and the density uneven phenomenon occurs.Have simple in structurely, cost is low, and filtration resistance is little, and retaining power is strong, long service life, advantage such as applied widely.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings
Fig. 1 is no backwash fabric filter structure cross-sectional schematic.
The specific embodiment
With reference to Fig. 1, no backwash fabric filter has container 1, on container 1 top Pressure gauge 12 is housed.Inlet tube and outlet tube 2,3 is set, upper and lower web plate 10,14 and fibrous filter layer 13 in container 1.Fibrous filter layer 13 is that some fibre bundles 9 are formed, and fibre bundle 9 selects for use the soft long fibre silk of suitable diameter, suitable length to become rope form, vertically ties up firmly with upper and lower web plate 10,14 with suitable filling density.Mediation water pipe 11 is set in fibrous filter layer 13, is connected with porous nozzle 15 on the mediation water pipe 11.The fibrolaminar net of supporting bucket 8 is set in container 1, and net bucket 8 is connected with following web plate 14, nets barrels 8, following web plate 14 can also be structure as a whole.In following web plate 14 lower ends is dividing plate 6.Dividing plate 6 is fixed on the container 1.Dividing plate 6 belows are provided with impurity settling chamber 4.Net bucket 8 is an impurity sedimentation passage 7 with the space of container 1 inwall, and this impurity sedimentation passage 7 is connected with impurity settling chamber 4.Lower end at container 1 is provided with the blow-off pipe 5 that is communicated with impurity settling chamber 4.
The filter process of no backwash fabric filter is: the water, the aqueous solution that need to filter enter in the fibrous filter layer 13 by water inlet pipe 2 under pressure, behind current process fibrous filter layer 13 filtration, purifications, discharge through outlet pipe 3.The minute impurities particle is held back by fibrous filter layer 13 in the water, and under the effect of water pressure, minute impurities is squeezed and concentrates and be sunken in the impurity settling chamber 4 through impurity sedimentation passage 7, finally discharges through blow-off pipe 5.When the motion process of minute impurities particle is obstructed, when promptly in fibrous filter layer 13, having impurity to pile up, give the mediation water pipe 11 logical press waters, the mediation current directly wash some fibre bundles 9 of fibrous filter layer 13 through porous nozzle 15, the sewage that has the minute impurities particle flow in the impurity settling chamber 4 along impurity sedimentation passage 7, discharges through blow-off pipe 5 again.
Claims (3)
