Welding one conical baffle 7 on cylinder 11 lower inner wall.Conical baffle 7 is divided into the two parts that are interconnected with housing 1 inside, and cleaning area 18 and bottom sedimentation district 8 are filtered in top.
The supporting arrangement 9 that is fixed on the conical baffle 7 comprises one a group of supporting gusset 91 and a minor axis 92.The middle part of minor axis 92 has a shoulder 93.The lower end of supporting gusset 91 is welded on the conical baffle 7, and the lower end is welded on the middle part shoulder 93 of minor axis 92.
Being fixed on screen pack bucket 2 on the supporting arrangement 9 comprises the cylinder 20 of a porous and removably is fixed on screen pack 25 on cylinder 20 outer walls.The upper and lower end of cylinder 20 is welded with a upper cover plate 21 and a lower cover 22 respectively.Be welded with a Upper shaft sleeve 23 and a Lower shaft sleeve 24 respectively at the center of upper and lower cover plate 21,22.Upper shaft sleeve 23 is sleeved on the water purification discharge pipe 51 that is positioned at housing 1 of pipe-line system 30.Lower shaft sleeve 24 is sleeved on the upper end of minor axis 92, is fixed on the minor axis 92 with screw.
Extremely shown in Figure 4 as Fig. 2, can be rotated to support on screen pack on the supporting arrangement 9 scrapes cleaning device 14 and comprises a rectangular frame 141, a plurality of U-shaped gathering sills 142 that are fixed on symmetrically on the rectangular frame 141 are contained in a spring 143 and a wiper or a scraper plate 144 in each gathering sill 142.Under the elastic force effect of spring 143, wiper 144 is pressed in certain suitable pressure on the surface of screen pack 25 of screen pack bucket 2.Center at the upper and lower crossbeam of rectangular frame 141 is welded a upper bush 145 and a lower sleeve 146 respectively.Upper bush 145 is sleeved on the water purification discharge pipe 51 that is positioned at housing 1 of pipe-line system 30, with lower sleeve 146 be sleeved on minor axis 92 on, thereby, screen pack is scraped cleaning device 14 can be rotated to support on the supporting arrangement 9.
As Fig. 1 and shown in Figure 5, the pipe-line system that is connected with housing 1 comprises a sewage induction pipe road 40, one water pipelines 50 and a blowoff line 60.Sewage induction pipe road 40 is communicated with cylinder 11 cuts.Water pipeline 50 comprises the water purification discharge pipe 51 that is positioned at housing 1 and is positioned at housing 1 water purification discharge pipe 52 outward, is connected by known one-tenth inserting structure between them.A plurality of holes 54 are arranged on the tube wall of water purification discharge pipe 51.The outer wall of water purification discharge pipe 52 and the gap between the inwall of the short tube 123 that upper cover 12 top center are welded seal with sealing ring.Water purification discharge pipe 52 has a valve 53.Blowoff line 60 comprises that a continuous blowdown pipeline 61 and is interrupted blowoff line 62.Continuous blowdown pipeline 61 is welded on low head 13 bottom centre.Continuous blowdown pipeline 61 is connected with interruption blowoff line 62, and they respectively have a valve 62 and a valve 63.
Continuous self-cleaning of the present utility model is washed fixed network formula filter when being used, 1 tangential direction enters housing 1 to sewage from sewage induction pipe road 40 along housing, and in housing 1 rotational flow, the water purification that filters by screen pack bucket 2 by water purification discharge pipe 51 the mouth of pipe and a plurality of holes 54 on the tube wall of water purification discharge pipe 51 enter water purification discharge pipe 51, upwards flow out along water purification discharge pipe 51 and water purification discharge pipe 52 by valve 53.Solid impurity in the sewage rotates with current, and shifts to the inwall of housing 1 under centrifugal action, sinks under the gravity effect, enters sedimentation district, bottom 8, is discharged from through valve 62 by continuous blowdown pipeline 61.
Under the hydraulic action of rotation, it will be the center rotation with the center line of housing 1 that the screen pack in cleaning area 18 is filtered on top is scraped cleaning device 14, thereby the screen pack 25 lip-deep suspensions that will be deposited on screen pack bucket 2 are removed.These suspensions enter sedimentation district, bottom 8 the most at last, are discharged from through valve 62 by continuous blowdown pipeline 61.
In case of necessity can open valve 63, deposit dirt is discharged through valve 63 by disconnected blowoff line 62 between more thorough, with row function between realizing.
In addition, also can filter cleaning area 18 to top and introduce backwashing water, to realize backwash with water purification discharge pipe 52 as recoil water inlet pipe to the screen pack 25 lip-deep suspensions of screen pack bucket 2.But when normal the use, a row and recoil are unnecessary.
The utility model has the advantages that: the filter self-cleaning, continuous blowdown, washer promotes with waterpower.
