The specific embodiment

Below in conjunction with drawings and Examples the utility model is elaborated.

Before the utility model is described in detail, be noted that in the following description content, similar elements is represented with identical numbering.

As shown in Figures 1 and 2, one first preferred embodiment of Scroll-tupe filter of the present utility model comprises the cylinder barrel 1 of a stainless steel and a filter element 2 that uprightly is contained in this cylinder barrel 1.

This cylinder barrel 1 has an influent stream mouth that is positioned at place, its top 11, one and is positioned at the filter head piece 12 at its place, top, a pressure relief opening 13 that is positioned at its place, top, and a sewage draining exit 14 that is positioned at its place, bottom.

This filter element 2 has a filter core 21 around a filter clear space 22, and a block gap is around this filter core 21 and the vibration filter screen 23 that matches and define a whirlpool space 24 with an internal face of this cylinder barrel 1.One end of this filter clear space 22 is communicated with this filter head piece 12, and an end in this whirlpool space 24 is communicated with this influent stream mouth 11 and this pressure relief opening 13, and the other end in this whirlpool space 24 then is communicated with this sewage draining exit 14.

Moreover the aperture of this filter core 21 is between 0.08 micron (μ m) is to 5 microns.This vibration filter screen 23 has a block gap around this filter core 21 and have the stratum reticulare body 231 of a plurality of filter openings 233, and multi-disc is obliquely installed the flow-disturbing teat 232 that surface and one side at this stratum reticulare body 231 connect described filter opening 233 respectively, particularly, the two angle theta of the surface of the bottom surface of described flow-disturbing teat 232 and this stratum reticulare body 231 is between 23 ° to 32 °; At present embodiment, the aperture of described filter opening 233 is 10 microns, described filter opening 233 is all del with described flow-disturbing teat 232, a top margin of each flow-disturbing teat 232 connects a top margin of corresponding filter opening 233, and the two angle theta of the surface of the bottom surface of described flow-disturbing teat 232 and this stratum reticulare body 231 is about 28.10 °.

The strobe utility of Scroll-tupe filter of the present utility model is, when leading a sewage body in the influent stream mouth 11 that enters this cylinder barrel 1, the L type flow passage structure design of the special angle by this influent stream mouth 11, make this sewage know from experience the place, top of the internal face that impacts earlier this cylinder barrel 1 up, then flow into down and also form spiral flowing in this whirlpool space 24 downwards, and impacting the surface of internal face and this vibration filter screen 23 of this cylinder barrel 1, in the process, suspended solids in this sewage body is under the influence of inertia and centrifugal action, can be thrown and hit and accumulate on the internal face of this cylinder barrel 1, simultaneously, this vibration filter screen 23 can produce vibration under powerful hydraulic pressure impacts, add 232 pairs of these sewage bodies of the above flow-disturbing teat and cause the flow-disturbing effect, can prevent effectively that suspended solids in this sewage body from passing through or adhere to, thus, this sewage body is after wearing this vibration filter screen 23 of filtration, contained suspended solids is almost by complete filtering, further wear again and filter this filter core 21 and behind this filter clear space 22 that arrives, make contained as virus, colloid, organic matter, materials such as germ are by filtering, so far just form a high-quality water purification body, this water purification body of filtering then upwards flows to discharge from this filter head piece 12, and the flow direction of above-mentioned whole filter process is shown in imaginary line arrow among Fig. 1.

As for, accumulate in the mud at the internal face place of this cylinder barrel 1, or, just can discharge to carry out subsequent treatment from the sewage draining exit 14 of this cylinder barrel 1 via the sewage that is produced after clear water or the air backwash procedure.

As shown in table 1, be further to utilize Scroll-tupe filter of the present utility model to come a herding waste water is carried out purified treatment, at first, this herding waste water must be earlier via carrying out pre-treatment as trash rack, and then enter in this Scroll-tupe filter and filter, the filtercondition that sets is the influent stream amount: 2.5 tons/hour, influent stream pressure: 5 kilograms/square centimeter, and with 1.5 tons/hour filter flow filter clean water body.By the water quality detection result shown in the table 1 as can be known, this burst herding waste water is after handling through Scroll-tupe filter of the present utility model, on the processing effect of projects such as biochemical oxygen demand (BOD), suspended solid amount and COD, not only have up to the removal efficient more than 75%, also far below the release concentration value of water discharge standard institute standard of Taiwan animal husbandry, prove that Scroll-tupe filter of the present utility model can reach splendid filtration effect really, make this burst herding waste water after handling, be reclaimed, circulate, utilize again.

[table 1]

Therefore, utilize this sewage body of control after importing, can carry out spiral quick flowing along this cylinder barrel 1 and 23 of this vibration filter screens, cooperate this vibration filter screen 23 when being subjected to high hydraulic pressure and impacting, can produce vibration to this sewage body, the flow-disturbing effect, make suspended solids in this sewage body at effect of inertia, centrifugal force, influence such as vibration force and flow-disturbing effect down, can efficiently be removed, this sewage body in percolation through this vibration filter screen 23 and when filtering subsequently through this filter core 21, be minimized the filtration load of this filter core 21, slow down its choking phenomenon, and then reduce the back washing frequency and increase the service life, thereby it is good to make the utility model integral body can produce the filtration effect, and running cost is low (as energy saving, low consumptive material), effect such as the little and applicability of space requirement is wide.

As shown in Figure 3, during actual the use, in order to improve treatment effeciency, several Scroll-tupe filters of the present utility model can also be connected in parallel, described Scroll-tupe filter can be arranged rectangular or annular, an and shared influent stream pipe 3, article one, filter stream is managed 4 and blow-off pipes 5, this influent stream pipe 3 links the influent stream mouth 11 of described Scroll-tupe filter, sewage physical efficiency in cesspool 6 is evenly divided via this influent stream pipe 3 and is delivered to described Scroll-tupe filter, this filter stream pipe 4 links the filter head piece 12 of described Scroll-tupe filter, the water purification physical efficiency that described Scroll-tupe filter is produced is confluxed to this filter stream pipe 4, and delivery, collection exists in the water purifying tank 7, and this blow-off pipe 5 is the sewage draining exits 14 that link described Scroll-tupe filter, compiles with the mud that described Scroll-tupe filter is discharged, be sent in the sludge-tank 8.Cooperate simultaneously automatically-monitored equipment again; as aerosol concentration, turbidity, flow according to the on-line monitoring water outlet ... etc. the water quality project; judge automatic back washing or change opportunity of filter material, or take place when unusual when a Scroll-tupe filter wherein, can give independent shutdown and keep in repair.

As shown in Figure 4, be one second preferred embodiment of Scroll-tupe filter of the present utility model, be that described filter opening 233 can be a semi-circular shape with the shape of described flow-disturbing teat 232 with the difference of above-mentioned this first preferred embodiment.
