With reference to shown in accompanying drawing 2, the present embodiment and embodiment one difference are: apparatus body is cylindrical tank body structure, this cylindrical tank body structure comprises tank body 21 and lid 22, filtering bodies 23 one-tenth reverse taper or back taper platform vibrational power flow are in apparatus body inside, more excellent scheme is: filtering bodies 23 is arranged on the junction of tank body 21 and lid 22 with the junction of apparatus body, inlet 24 is arranged on the sidewall of tank body 21, sewage draining exit 26 is arranged at the bottom of tank body 21, liquid outlet 25 is arranged at the center of lid 22, namely the center line of liquid outlet 25 overlaps with the axis of tank body 21.Certainly, the center line of liquid outlet 25 also can not overlap with the axis of tank body 21, as shown in Figure 3.All the other structures, with above-described embodiment one, no longer describe.
Embodiment three
With reference to shown in accompanying drawing 4, the present embodiment three is with the difference of embodiment two: the reverse taper of filtering bodies 33 or the openend of back taper platform structure are inclined plane, it is inclined on tank body 31 inwall, liquid outlet 35 is arranged on the sidewall of tank body 31 of tapping side, its cavity surrounded with filtering bodies 33 inwall and tank body 31 communicates, and sewage draining exit 36 is arranged at the bottom of tank body 31.All the other structures, with above-described embodiment two, no longer describe at this.
Liquid filter method of the present invention is: liquid to be filtered filters inside the lateral of conical filter net, namely flow in apparatus body from inlet, and the liquid after conical filter body filters flows out from liquid outlet.Along with the carrying out of filtering, the impurity assembled in the dirty chamber of collection and the impurity be attached in filtering bodies increase gradually, pressure reduction between inlet and liquid outlet is increasing, when pressure reduction reaches predetermined value, open sewage draining exit, liquid to be filtered still filters normal through filtering bodies, collects the impurity assembled in dirty chamber and flows out from sewage draining exit with part liquid to be filtered, simultaneously because the fluid pressure after filtration is greater than sewage draining exit pressure, the fluid after part is filtered is reverse to flow out from sewage draining exit through filtering bodies.When pressure reduction is reduced to preset value, close sewage draining exit, continue to filter.
The work principle of filter of sedimeter of the present invention is as follows:
1, filter process: adopt conical filter body structure and from conical filter external body filtered version internally, makes liquid to be filtered from tangential by filtering bodies, forms velocity gradient and shearing force, decrease moisture film and form probability on filtering bodies surface.When liquid to be filtered flows through filtering bodies, the impurity that the particle diameter contained by it is greater than filtering bodies filtering accuracy is filtered body and is trapped in the dirty chamber of collection; Close under the effect that the impurity of filtering bodies filtering accuracy reduces at the radial latus rectum of velocity gradient, shearing force and sieve meshes, also be aggregated in the dirty chamber of collection, only there are a small amount of viscosity or flocculence material can assemble blocking mesh, and under the effect of liquid sticky power, form moisture film at filtering bodies mesh place, increase drag losses when filtering; The impurity that particle diameter contained by it is less than filtering bodies filtering accuracy flows out from liquid outlet with liquid.
2, blowdown process: along with the carrying out of filtering, the impurity assembled in the dirty chamber of collection and the impurity be attached in filtering bodies increase gradually, and the pressure reduction between inlet and liquid outlet is increasing, and when also just showing that fluid is filtered, drag losses is in rising.Now open sewage draining exit, collecting the impurity built up in dirty chamber directly relies on gravity to discharge from sewage draining exit, now liquid to be filtered major part is still filtered normal through filtering bodies, small part liquid to be filtered flows out from sewage draining exit, simultaneously because the liquid to be filtered pressure of filtering bodies outside reduces, cause filtering bodies internal liquid pressure to be greater than sewage draining exit pressure, Partial filtration body internal liquid is from its interior externally adverse current.Because conical filter body is when normal filtration, filtered boundary forms velocity gradient and hydrodynamic shear, and the flip-flop of filtered boundary can create local obstruction during adverse current, liquid to be filtered can cause blending strong between the inner particle of liquid stream when walking around filtering bodies filter screen border, relative motion, the impurity being simultaneously blocked in filtering bodies is separated from filter screen, liquid forms turbulent flow at filter screen outer surface, again along with the discharge of impurity, turbulent flow is formed at filter screen outer surface, then under turbulent flow and turbulent effect, the moisture film formed during normal filtration is destroyed, drag losses declines, so the dirty chamber of collection and the impurity be blocked on filter mesh are not only discharged from sewage draining exit by this blowdown process, and screen pack is brought back to life.Meanwhile, the diameter due to sewage draining exit will be far smaller than the diameter of inlet and liquid outlet, thus still can normally continuous filtration when filtering bodies brings back to life blowdown.
The present invention, owing to adopting the version of conical filter body reverse filtration, makes screen pack under the condition that mesh aperture is identical, and filtering accuracy improves 1-2 grade.Unique physical design makes filtering accuracy higher than order number corresponding to mesh aperture.And traditional structural design makes filtering bodies filtering accuracy equal with sieve meshes aperture order number.
The present invention makes full use of sewage draining exit when opening, the change collecting pressure differential between dirty chamber and filtering bodies inside and the flow direction realizes the self-cleaning resurrection of filtering bodies, utilize the pressure current of liquid to be filtered to rinse to be gathered in collect dirty chamber impurity, utilize pressure differential flushing to be blocked in impurity on filtering bodies filter screen, to utilize the turbulent flow and turbulent flow that produce in fluid motion process, destroy moisture film, then bring back to life filter membrane without the need to arranging the filtering bodies such as backwash, cleaning brush, absorption suction nozzle.
Liquid to be filtered of the present invention flows through filtering bodies from filtering bodies outside, flow out from filtering bodies inside, liquid to be filtered directly communicates with sewage draining exit, the liquid of discharging during blowdown is liquid to be filtered and filtered mixed liquid, overcome conventional filtering techniques to be communicated with liquid after filtering by sewage draining exit, the liquid of discharge is all the change of filtered liquid, this structure, make blowdown liquid impurity concentration high, filter liquide blowdown consumption reduces more than 50%.
The features such as the present invention has that structure is simple, filtering accuracy is high, blowdown flow rate is few, investment and operating cost is low, convenient operating maintenance.
The above; it is only preferred embodiment of the present invention; not do any pro forma restriction to the present invention, those skilled in the art utilize the technology contents of above-mentioned announcement to make a little simple modification, equivalent variations or modification, all drop in protection scope of the present invention.
