Detailed description of the invention
Embodiment of the present utility model is illustrated below in conjunction with accompanying drawing.
Generally at the inlet channel 1 being arranged over for intaking of side, filter tank, this inlet channel is connected to the inlet pipeline being provided with water intaking valve 2.Former water to be filtered enters filter tank from inlet channel 1.The filter material layer for filtering it is provided with in filter tank.The outlet 5 for discharging filtered fluid it is connected with in filter tank.Former water enters behind filter tank, with gravity leakage through filter material layer, and to merge into the collecting chamber below filter material layer after the head filtration that weighs, after flowed out by outlet 5.When backwash, it is with valvular pipeline to connect air pump 4 and water pump 3 respectively at outlet 5 place by corresponding, rinses filter material layer by pumping into the mode direction of air-flow or current from outlet.Arranging flap valve 14 on the sidewall in filter tank, the water in backwash process flows into drainage ditch by flap valve 14, and is discharged by discharge outlet.This utility model is in order to realize the accurate control of backwash real machine and washing time, the drainage ditch place being connected at outlet 5 place and flap valve 14 is respectively arranged to delivery turbidity instrument 7 and the drainage turbidity instrument 16 of detection water quality, starts by detecting Water-quality control backwash or terminates.Described filter tank is provided with on the pipeline that liquidometer, air pump 4 and water pump 3 connect and is all connected to effusion meter, the pipeline that air pump 4 is connected with outlet 5 is provided with non-return valve 10.
Under normal circumstances, in drainage procedure, trapped substance can not rapidly be excluded, and particularly from flap valve trapped substance farther out, the mode only by limit bath limit draining makes trapped substance be discharged, this process can cause substantial amounts of filterins media run-off, wastes water and electric energy simultaneously.The discharge of foreign material during in order to be beneficial to backwash, accelerate backwash process, the air-blowing float tube 11 that blowing direction is relative with flap valve 14 is set in filter tank, blow to the trapped substance certain power of offer on liquid level by air-blowing float tube, help trapped substance quickly to discharge filter tank, greatly reduce the loss of filtrate.Air-blowing float tube 11 can include a gas blow pipe for blowing, and it is arranged on a floating thing, and is connected with source of the gas by flexible pipe.In order to limit its position on liquid level, the guiding mechanism such as guide rod, chute can also be set to guide it to fluctuate.
Concrete control method is: when running well in filter tank, by being arranged on the delivery turbidity instrument 7 monitor in real time effluent quality of filter tank outlet 5, when delivery turbidity is more than setting value, namely judges that effluent quality is defective, it is necessary to carry out backwash operation.Now namely automatically controlling closedown water intaking valve 2, booster air pump and water pump carry out backwash according to the program of backwash successively.In backwash process, utilizing filter tank ullage to float the air-blowing float tube 11 arranged to the air blowing of flap valve 14 direction level, the foreign material to accelerate ullage discharge filter tank by flap valve.In the whole process of backwash, utilize the drainage turbidity instrument 16 monitor in real time draining water quality being arranged on discharge outlet place, can be judged as that filtrate is rinsed well when drainage turbidity is less than setting value, automatically control stopping backwash operation, return to normal filtration.
Generally, backwash process is divided into gas punching, mixing wastewater with air punching and water to rush three phases.The stage is rushed, only booster air pump, by gas shock filtrate at gas.Mixing wastewater with air rushes stage booster air pump and water pump simultaneously, mixes with a certain proportion of air-flow and current and impacts filtrate.Water rushes the stage and then closes air pump, only rinses filtrate by current.Form current owing to only having new water to flow into filter tank in mixing wastewater with air punching and the water stage of rushing and discharge from flap valve, thus only can start air-blowing float tube 11 level in mixing wastewater with air punching and/or water punching and blow.The present embodiment selects only utilize air-blowing float tube 11 to blow in the water stage of rushing.
Foreign material in order to ensure filter tank ullage can flow out from flap valve smoothly, should ensure that the position of liquid level and flap valve adapts.Liquid level can pass through flap valve 14 and water pump 3 controls.When draining, if filtrate does not precipitate, it is possible to be lost in drainage ditch with discharging water.Therefore, use servomotor stepless time adjustment characteristic can continuously, accurately control the aperture of flap valve, when draining starts, the aperture of flap valve is gradually increased with liquid level reduction in filter tank, the liquid and the trapped substance that make the only the superiors in filter tank are discharged in drainage ditch, reduce the loss of filtrate.
Because source quality is affected by factors such as time, season, weather, so filter material layer trapped substance also differs, different trapped substances, required back washing strength is also different, converter is utilized to regulate the frequency of air pump, water pump, just can regulate backwash frequency, to reach the intensity controlling backwash of intelligence.
For avoiding the water in collecting chamber to pour in down a chimney air pump, except the connecting line of air pump can being set to inverted U-shaped pipeline, non-return valve 10 also can be installed on the pipeline that air pump 4 is connected with outlet 5, form duplicate protection, make production safer, reliably.
