The Inlet and outlet water structure of the fibre turntable filter that the utility model provides, comprise water inlet 1, delivery port 11 and filter chamber 12, rotation filter disc 13 is installed in the filter chamber 12, water flows to filter chamber 12 from water inlet 1, filter through rotation filter disc 13, the delivery port 11 that is connected by the water side 14 with rotation filter disc 13 flows out again.Be provided with influent weir around the inwall of filter chamber 12, influent weir is communicated with water inlet 1.
Influent weir can be divided into water inlet end influent weir 3, side influent weir 20 and water side influent weir 6 according to the shape of filter chamber 12.Filter chamber 12 is provided with deflector 4, and deflector 4 and the supporting use of influent weir slow down the into flow velocity of water.Deflector 4 corresponding water inlet end deflector 19, side deflector 21 and the water side deflectors 22 of also can being divided into.Deflector is divided into upper hem 17 and lower hem 18, and upper hem 17 and influent weir are vacated the distance of water overflow, and lower hem 18 tilts to filter chamber's inwall, with the water guiding filter chamber inwall of overflow.With the distance of vacating the water overflow near the upper hem 17 of the supporting water inlet end deflector 19 of the water inlet end influent weir 3 of water inlet and influent weir, lower hem 16 is parallel with filter chamber's inwall.
Also be provided with into water surge chamber 2 between water inlet 1 and the influent weir, the height of water inlet 1 is lower than the height of influent weir.Be provided with water outlet surge chamber 8 between the water side 14 of rotation filter disc 13 and the delivery port 11, water outlet surge chamber 8 is provided with dividing plate 23; Dividing plate 23 is divided into stationary barrier 10 and active clapboard 9, and active clapboard 9 is set on the stationary barrier 10, and active clapboard 9 can be up and down, regulates the height of dividing plate 23.
The operation principle of the fibre turntable filter that the utility model provides is as follows:
The sewage of handling through sedimentation basin at first enters into water surge chamber 2 by water inlet 1, enter in the influent weir that is encircling around filter chamber's inwall by water inlet surge chamber 2, crest of weir by influent weir is to rotation filter disc 13 water distribution uniformities, make water body to rotating the disturbance minimum of filter disc 13, guarantee rotation filter disc 13 static drainages.Under the effect of hydraulic pressure, enter in the rotation filter disc 13 behind the water distribution, and flow to water outlet surge chamber 8, flow out by delivery port 11 by the dividing plate 23 buffering backs of water outlet surge chamber 8 by the water side 14 of rotation filter disc 13 through the clear water after filtering.The fiber filter cloth of rotation filter disc 13 can be close on the base fabric under the hydraulic pressure effect automatically, form the filtration of dense layer, the mud granule suspension can be piled up gradually on its surface, because filter cloth adopts hydrophobic nylon, polyester fiber material to make, the mud granule suspension is difficult for cohering, rotation filter disc 13 is again a vertical design, so the mud granule suspension deposits at the bottom of the pond easily.The mud granule suspension forms mud after pond bottom sediments a period of time, PLC can open the mud at the bottom of the motor-driven valve 5 that is connected with extraction mud pipe, the back suction sucking pump 7 suction ponds termly, and mud enters through the mud-suction hole on the extraction mud pipe that to discharge the pond in the extraction mud pipe more external.
In addition, when the water level in the body of pond has surpassed setting value, liquid level gauge can be passed to PLC to this signal, PLC opens the motor-driven valve 5 that is connected with connecting pipe, back suction sucking pump 7, the double sucker 24 that rotates filter disc 13 dual-sides this moment carries out back suction to rotation filter disc 13 simultaneously and inhales under the suction function of back suction sucking pump 7, disorderly and unsystematic, crisscross, be close to fiber cloth silk on the base fabric before the suction inlet that enters double sucker 24 earlier through the combing of broach and the direction unanimity that becomes, the fiber cloth silk becomes fluffy upright back suction suction state by the filtration state of dense layer then, and the settled sludge on the filter cloth is by sucking-off smoothly.When back suction is inhaled, drive motors drives driving mechanism and then drives whole hollow water outlet axle, arc connector, rotation filter disc 13 and slowly rotates, revolving turns around finishes the back suction suction process of rotating filter disc 13 to, PLC stops just finishing the motor-driven valve 5 that back suction is inhaled process then, open next motor-driven valve 5 and carry out next back suction suction process of rotating filter disc 13, all cleaned up to every group of rotation filter disc 13, finished a back suction and inhale process.When suspension in the sewage too much causes the processing water yield to descend, the back suction that front and back are twice is inhaled the time interval can be less than the time of setting, PLC can start two back suction pulsating pumps 7 simultaneously and corresponding motor-driven valve 5 carries out the back suction suction, shorten back suction and inhale the time, guaranteeing still can operate as normal under the impact of high load capacity.Back suction pulsating pump 7 is delivered to the front end water inlet system with the mud that pumps out and is disposed.
The Inlet and outlet water structure of the fibre turntable filter that the utility model provides, water flows to the filter chamber from water inlet, filters through the rotation filter disc, and the delivery port that is connected by the water side with the rotation filter disc flows out again, be provided with influent weir around the inwall of filter chamber, influent weir is communicated with water inlet; The filter chamber is provided with deflector, and the supporting use of deflector and influent weir slows down the into flow velocity of water.Compared with prior art, the Inlet and outlet water structure of the fibre turntable filter that the utility model provides reduces water velocity aspect two, reach water distribution uniformity, the first, be provided with influent weir around filter chamber's inwall, influent weir is communicated with water inlet, long 3 times-4 times of the influent weir that influent weir total length all around is provided with than a monolateral end makes the load of water overflow of influent weir crest of weir reduce, and has reduced the flooding velocity of water; The second, water is after the influent weir overflow, deflector further reduces the flow velocity of water, make water slowly enter the filter chamber along deflector, reach water distribution uniformity, reduce the purpose of current, make the fibre turntable filter be in the state of static filtering, reduce the disturbance of current, improve filter efficiency settled sludge.
Especially, the deflector of the Inlet and outlet water structure of the fibre turntable filter that provides of the utility model and the distance that influent weir is vacated the water overflow; Deflector tilts to filter chamber's inwall, water guiding filter chamber inwall with overflow, reduce the direct impact of water, can reduce, reduce disturbance the mud on being deposited at the bottom of the pond, filter chamber to being deposited on the disturbance of the mud of rotation on the filter disc to the rotation filter disc of fibre turntable filter.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined herein General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
