Description
Technical field
The present invention relates to a kind of water fetching device, particularly a kind of filtration water fetching device be fixed on bottom the close water source, bank such as rivers, lakes and reserviors.This immersion filters water fetching device can be applied to the water treatment field such as the Drinking Water of polluted source and the pretreatment of water for industrial use.
Background technology
Current, the intake end of Drinking Water and water for industrial use is provided with grid, in order to tackle foreign material thick in water, between pump house water inlet, is provided with dull and stereotyped graticule mesh, in order to tackle foreign material more tiny in water.This water-supply method is merely able to stop water pump to suck foreign material, ensures that water pump normally runs, can not play due preliminary filtering function to the water treatment technology of waterworks.
Summary of the invention
The object of this invention is to provide a kind of immersion and filter water fetching device, that immersion filtration water fetching device is set at the water intaking end of Drinking Water and water for industrial use water supply plant, not only can stop suction foreign material, effectively can also remove the impurity particle in former water, improve effluent quality, simultaneously for the cleaning process of filtrate creates better technology mode.
A kind of immersion filters water fetching device, comprise support, tank body, grid, filtrate, catch net, palisade collector pipe and outlet pipe, be characterized in that support installing is held in water supply plant water intaking and is fixed on bottom water source, described tank body is positioned at support, tank base is provided with grid, filtrate is provided with in tank body, tank body upper end communicates with air, catch net is provided with above filtrate, the porose arrangement of palisade collector pipe sidewall be arranged at above catch net is palisade, described palisade collector pipe is connected from tank body side with outlet pipe, outlet pipe is flexible pipe, be connected to pump house pulsating pump, lifting arrangements for speed regulation are provided with above support, these lifting arrangements for speed regulation comprise motor, reel and rope, motor connects with reel, rope is wrapped on reel, the rope other end is connected with tank body.Described motor is variable-frequency motor.During described lifting arrangements for speed regulation work, hoisting velocity is 0.5 ~ 1.0m/s, and hoisting depth is 2.0 ~ 3.0m.
Owing to being provided with filter course on water fetching device, former water through filtering layer in upward flow mode, effectively can be removed the impurity particle such as pollutant and algae in former water, reduce the turbidity of former water.Filter and terminate, promote tank body, the clear water being positioned at catch net top rinses filter material layer downwards under gravity, filtrate is made to reach fluidized state, be retained in pollutant in filtering layer to split away off from filter material surface under the double action of current shearing and filtering material particle collision friction, realize effectively cleaning filtrate.According to the water quality condition of former water at Various Seasonal and different times, by regulating the rate of climb of the FREQUENCY CONTROL tank body of variable-frequency motor, the cleaning performance that filtrate reaches best can be made.Owing to effectively removes impurity particle, the wearing and tearing to pulsating pump can be reduced, extend the service life of water pump.Through the primary filter of water intaking end, the dosage of waterworks coagulant and disinfectant can be reduced on the one hand, reduce the content of aluminium salt and DBPs in the rear water of filter, the scale of water factory's water treatment building can be reduced on the other hand, save water factory's floor space and investment.This immersion filters simple and reliable for structure, the small investment of water fetching device, occupation of land is little, convenient operation and management, operation cost are low, the process water yield is large, purification efficiency is high.
Accompanying drawing explanation
Fig. 1 is that immersion of the present invention filters water fetching device schematic diagram.
Fig. 2 is palisade collector pipe schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, the enforcement that immersion filters water fetching device is described further.
Fig. 1 is that immersion filters water fetching device, is fixed on river, lakes and reserviors etc. bottom the water source on bank, comprises support 1, tank body 2, grid 3, filtrate 4, catch net 5, palisade collector pipe 6, outlet pipe 7 and promotes arrangements for speed regulation.Tank body 2 is positioned at support 1, is provided with grid 3 bottom tank body 2, and the larger foreign material of volume tackled by grid 3, and the upper end of tank body 2 communicates with air, are provided with filtrate 4 in tank body 2, and filtrate 4 is the granules of polystyrene that proportion is lighter than water.The particle size range of polystyrene thickness of filter bed, filtrate and size grading are determined according to the water quality condition of Practical Project Central Plains water.Be provided with catch net 5 above filtrate 4, the aperture of catch net 5 is less than the diameter of filtrate, and filtrate is separated with clear water.See that the palisade collector pipe 6 of Fig. 2 is arranged at above catch net 5, the porose arrangement of palisade collector pipe 6 sidewall is palisade.Palisade collector pipe 6 picks out from tank body 2 side, is connected with outlet pipe 7, and outlet pipe 7 is flexible pipe.Outlet pipe 7 is connected to pump house pulsating pump.When after starting mode of pump, produce negative pressure in tank body 2, former water through grid 3, filters through polystyrene filter medium 4 filtering layer in upward flow mode, enters palisade collector pipe 6, enter pump house from outlet pipe 7 bottom tank body 2.Former water enters water supply plant after primary filter.Through filtration after a while, the impurity of filtrate trapped inside is many, affects filter effect, needs to rinse filtrate 4.Be provided with lifting arrangements for speed regulation above tank body 2, these lifting arrangements for speed regulation comprise motor 10, reel 8 and rope 9, and motor 10 connects with reel 8, and rope 9 is wrapped on reel 8, and rope 9 other end is connected with tank body 2.Motor 10 is variable-frequency motor, and movable reel 8 is with by motor 10, pulls rope 9, and the tank body 2 of the following hanging of rope 9 is promoted by with speed faster, and hoisting velocity is 0.5 ~ 1.0m/s, and hoisting depth is 2.0 ~ 3.0m.Hoisting velocity can be realized by the frequency adjusting variable-frequency motor 10.The clear water be stored in above catch net rinses filtrate 4 downwards, and the impurity particle in filtrate enters water body downwards.Tank body 2 arrives the height of setting, completes filtrate cleaning.Tank body 2 uniform descent, to position time initial, starts the filtration water intaking operation of next filter cycle.According to test: the diameter of filter tank body is 2.5m, height is 3.0m, and the clear water zone height above filtrate is 1.0m, and granules of polystyrene filter height is 1.0m.When filtering velocity is 40m/h, when raw water turbidity is 40 ~ 50NTU, delivery turbidity is after filtering 30 ~ 35NTU, and turbidity average removal rate is 25 ~ 30%.Other auxiliary characteristics, chroma removal rate is 8%, BOD clearance be 12%, COD clearance is 6%, and ammonia nitrogen removal frank is 3.5%.Served as the filter water fetching device loss of flood peak when reaching 2m, filtration time is 6.5h.Filter cycle terminates, and carries out backwash to filtrate, and tank body hoisting velocity is 0.5 ~ 1.0m/s.Test achieves the good result of expection.
