See also Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 1 is the structural representation of fibre turntable filter in the utility model, and the direction of arrow is water (flow) direction among the figure; Fig. 2 is the cross section structure figure of fibre turntable filter among Fig. 1, and the direction of arrow is water (flow) direction among the figure; Fig. 3 is not for comprising the structural representation of the rotation filter disc of back suction sucker among Fig. 1; Fig. 4 is the structural representation that Fig. 1 turntable fritter is connected with arc connector.
The novel rotation filter disc of the fibre turntable filter that the utility model provides, comprise rotating disk fritter 13, rotating shaft 14 and back suction sucker 6, rotating disk fritter 13 surfaces are provided with filter course 21, rotating shaft 14 is provided with hollow duct, sewage enters into water surge chamber 2 by water inlet 1, enter influent weir 3 by water inlet surge chamber 2,3 overflows flow to filter chamber 12 through influent weir, flow to water outlet surge chamber 8 through the hollow duct by rotating shaft 14 after filter course 21 filtrations of rotating disk fritter 13 again, flow out by delivery port 11 by the dividing plate buffering back of water outlet surge chamber 8.Dividing plate 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.Back suction sucker 6 is fixed on the inwall 15 of filter chamber 12 by installing rack 16, and back suction sucker 6 is close on the filter course 21, is used for the mud on the back suction removing filter course 21.Back suction sucker 6 is connected with extraction mud pipe 17, by control valve 5 control back suction sucking pumps 7 the mud suction is scavenged into the external world.Deflector 4 cooperates with influent weir 3, plays the effect of water distribution uniformity.
The cross section of rotating shaft 14 is the regular polygon structure, and rotating disk fritter 13 is a sector structure, and the outer ring 22 and the inner ring 20 of rotating disk fritter 13 are arc, and rotating disk fritter 13 is connected with rotating shaft 14 by arc connector 18; Arc connector 18 is the plane with rotating shaft 14 contact-making surfaces, and arc connector 18 is a cambered surface with the contact-making surface of rotating disk fritter 13, and the cambered surface of arc connector 18 offers the hollow duct that water hole is connected rotating disk fritter 13 and rotating shaft 14 with the plane; The radius that the length of back suction sucker 6 equals the outer ring 22 of rotating disk fritter 13 deducts inner ring 20 radiuses of rotating disk fritter 13.Rotating disk fritter 13 comprises skeleton 19 and filter course 21, and filter course 21 is a fiber filter cloth, and fiber filter cloth is wrapped in the skeleton 19 outer internal cavities that form, and rotating disk fritter 13 is provided with the flow export of internal cavities in inner ring 20 cambered surfaces.Fiber filter cloth is mainly made by the nylon Polyester Fibers.Arc connector 18 is connected with rotating shaft 14 by bolt, has avoided the welding deformation with rotating shaft 14.
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 rotating disk fritter 13 water distribution uniformities, make water body to the disturbance minimum of rotating disk fritter 13, guarantee rotating disk fritter 13 static drainages.Under the effect of hydraulic pressure, enter in the rotating disk fritter 13 through the clear water after filtering, and flow to water outlet surge chamber 8 behind the water distribution, flow out by delivery port 11 by the dividing plate buffering back of water outlet surge chamber 8 by the water side 14 of rotating disk fritter 13.The fiber filter cloth of rotating disk fritter 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, rotating disk fritter 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 control 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 control valve 5 that is connected with connecting pipe, back suction sucking pump 7, this moment, the back suction sucker 6 of rotating disk fritter 13 dual-sides carried out the back suction suction to rotating disk fritter 13 simultaneously 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 back suction sucker 6 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 rotating shaft 14, arc connector 18, rotating disk fritter 13 and slowly rotates, revolving turns around finishes the back suction of a rotating disk fritter 13 is inhaled process, PLC stops just finishing the control valve 5 that back suction is inhaled process then, open the back suction that next control valve 5 carries out next rotating disk fritter 13 and inhale process, all cleaned up to every group of rotating disk fritter 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 sucking pumps 7 simultaneously and control corresponding 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 sucking pump 7 is delivered to the front end water inlet system with the mud that pumps out and is disposed.
Compared with prior art; the back suction sucker of the novel rotation filter disc of the fibre turntable filter that the utility model provides is when sucking sludge; because the back suction sucker is fixing; the rotation filter disc rotates; the back suction sucker can all can aspirate cleaning with the filter course all surfaces on the rotating disk fritter, and the back suction sucker can not bump to rotating shaft, also can not stay the suction dead angle on filter course; the protection filter course, the service life of prolongation filter course.
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.
