Description
Technical field
The utility model relates to a kind of filter plant, is specially a kind of backwash filter.
Background technology
Along with the scarcity of water resources and the day by day serious of water pollutions, people to living environment and quality more and more higher, the process of waste water and recovery become the important component part of industrial production and resident living day by day, backwash filter can solve the problem of wastewater treatment and recycling, but the backwash filter of prior art still exists, and process is discontinuous and floor space is large, deadweight has the deficiencies such as impact to filtration procedure, filtering head is topmost parts in backwash filter, the filtration of liquid mainly completes in filtering head, but the filtering head of prior art is all vertical placement, due to the effect of gravity, during vertical placement, in filtering head, the filtering table with a certain distance from fixed support be positioned at bottom filtering table group cannot form hole when back flushing, cause filtered liquid skewness, backwashing pressure is excessive, need by external source pump to backwashing pressure, the gravitional force of filtered liquid self can not meet the pressure of back flushing, in addition, backwash filter, that a kind of filter screen that utilizes directly tackles impurity in water, remove water body recovery technology, particulate matter, reduce turbidity, purify water, minimizing system dirt, bacterium algae, the generations such as corrosion, with the precision equipment purified water and other equipment of securing system normally work, realize intelligentized equipment, a filtering layer or adsorption layer are only set in the backwash filter of prior art, can not effectively except the impurity in anhydrating, the effect better can not played precipitation and filter, the result of final back flushing is affected, and can not effectively play reduction turbidity, the effect purified water.
Summary of the invention
The purpose of this utility model is to change filtering head into horizontal positioned by vertically placing, avoid the phenomenon of filtered liquid skewness, simultaneously, when back flushing, because filtered liquid has certain gravitional force, so only need very little backwashing pressure, no longer need external source pump to backwashing pressure, the gravitional force of filtered liquid self just can meet the pressure of back flushing, therefore, provides a kind of backwash filter.
For achieving the above object, by the following technical solutions, the utility model comprises water tank 1, inlet damper 2, water inlet pipe 3, eduction pipe 4, water inlet pipe control valve 5, filter plate 6, filtering head 7, back flushing water shoot 8, feet 9, gac 10, alum 11, supporting layer 12, water outlet baffle plate 13, it is characterized in that, the mid-way of the inner tip of water tank 1 is provided with inlet damper 2, the outer tip end of water tank 1 is provided with water inlet pipe 3, water inlet pipe 3 is provided with eduction pipe 4, the bottom of water inlet pipe 3 is provided with water inlet pipe control valve 5, the inside of water tank 1 is provided with gac 10 and alum 11, and alum 11 is placed in the top of gac 10, the inside of water tank 1 is provided with filter plate 6 and supporting layer 12 near the position of bottom, and filter plate 6 is placed in the top of supporting layer 12, the inner bottom of water tank 1 is provided with water outlet baffle plate 13, the position that the external bottom end of water tank 1 keeps left is provided with feet 9, and the position that the external bottom end of water tank 1 is placed in the middle is connected with one end of back flushing water shoot 8, and the other end of back flushing water shoot 8 is provided with the filtering head 7 of horizontal positioned.
The beneficial effects of the utility model are:
Changing filtering head into horizontal positioned by vertically placing, avoiding the phenomenon of filtered liquid skewness, not needing the pressure that just can meet back flushing by external source pump, reduce cost.
Increase an adsorption layer, can more effective removing impurity, so that the running of better maintenance system.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation
Fig. 2 is the enlarged view of the utility model filtering head 7.
In figure: water tank 1, inlet damper 2, water inlet pipe 3, eduction pipe 4, water inlet pipe control valve 5, filter plate 6, filtering head 7, back flushing water shoot 8, feet 9, gac 10, alum 11, supporting layer 12, water outlet baffle plate 13.
Embodiment
Example 1
A kind of backwash filter, comprises water tank 1, inlet damper 2, water inlet pipe 3, eduction pipe 4, water inlet pipe control valve 5, filter plate 6, filtering head 7, back flushing water shoot 8, feet 9, gac 10, alum 11, supporting layer 12, water outlet baffle plate 13, it is characterized in that, the mid-way of the inner tip of water tank 1 is provided with inlet damper 2, the outer tip end of water tank 1 is provided with water inlet pipe 3, water inlet pipe 3 is provided with eduction pipe 4, the bottom of water inlet pipe 3 is provided with water inlet pipe control valve 5, the inside of water tank 1 is provided with gac 10 and alum 11, and alum 11 is placed in the top of gac 10, the inside of water tank 1 is provided with filter plate 6 and supporting layer 12 near the position of bottom, and filter plate 6 is placed in the top of supporting layer 12, the inner bottom of water tank 1 is provided with water outlet baffle plate 13, the position that the external bottom end of water tank 1 keeps left is provided with feet 9, and the position that the external bottom end of water tank 1 is placed in the middle is connected with one end of back flushing water shoot 8, and the other end of back flushing water shoot 8 is provided with the filtering head 7 of horizontal positioned.
Open water inlet pipe control valve 5, water flows in water tank 1 along water inlet pipe 3, once filter time in water tank 1 through alum 11, alum 11 can adsorb the impurity be suspended in water, make it to settle from water, water after filtration is carrying out secondary filtration through gac 10, gac 10 can carry out disinfection to water quality, purify water, and can impurity in planar water, make water quality more aseptic, health, filter plate 6 plays the dual function of the filtration of carrying filter material layer and back flushing water distribution in water tank 1, supporting layer 12 prevents filterins media run-off when filtering, and play booster action when back flushing, filtering head 7 horizontal positioned, filtered liquid just can be uniformly distributed, simultaneously, when back flushing, because filtered liquid has certain gravitional force, so only need very little backwashing pressure just can play the effect of back flushing, when opening back flushing water shoot 8, impurity particle is discharged together.
