Specific embodiment
The utility model is further described with reference to the accompanying drawing:
In conjunction in Fig. 1, a kind of filter device, including outer barrel 10 and the interior bucket 20 being arranged in outer barrel 10；The interior bucket 20
Outer ring is arranged with water-insulating cover 30；Water-insulating cover 30 is circumferentially positioned at the outside of interior bucket 20；
Between the water-insulating cover 30 and the interior bucket 20 be return water layer, between the water-insulating cover 30 and said tub 10 for into
Water layer 40；The outer barrel 10 on water inlet 40 top of layer is equipped with water inlet；Sewage is entered from the inlet into water layer 40, then downwards
Flowing；
The upper end of the interior bucket 20 and the water-insulating cover 30 is all connected to top surface in said tub 10；So that return water layer and
Only have bottom to communicate between water inlet layer 40；
In conjunction in Fig. 2,10 space of outer barrel of 30 lower section of water-insulating cover is settling zone 50, is flowed downward from water inlet layer 40
Water some bulky grain suspended matters behind settling zone 50 sink under the influence of gravity；50 bottom margin of settling zone is equipped with arc
Portion 60,50 bottom surface of the settling zone middle part are equipped with reflow bump 61；After the water in layer 40 of intaking flows downward, along curved portion
As soon as 60 form a convolution flow direction, reflow bump 61 is then hit with the trend that backs up, bulky grain suspended matter is just at this time
It has been deposited between two protrusions, small granular suspended matters will be sprung up upwards, into water-insulating cover 30, travel further into return water layer
In；
Constantly enter with dampening, the hydraulic pressure in return water layer gradually increases, and then just enters from the filter hole of 20 side wall of interior bucket
Interior bucket, filter hole are provided with 203 middle and lower part of packing layer, are filtered, and sewage is by packing layer 203 first by large granular impurity mistake
Filter, then water continue on pour into filter assemblies 201 further progress and filter；
It is equipped with mud discharging mouth 62 between the reflow bump 61 and the curved portion 60, when sludge impurities accumulation to certain journey
It opens mud discharging mouth 62 after degree impurity is discharged, since the setting of mud discharging mouth 62 is in bottom and top is impurity, so in spoil disposal mistake
Sludge is isolated by water with mud discharging mouth 62 in journey, reduces influence of the spoil disposal process to water flow；
Multilayer is also classified into filter assemblies 201；The interior bucket 20 is water purification layer 22 and filter assemblies 21 from top to bottom；It is described
Filter assemblies 21 are secondary filter component 201, packing layer 203 from top to bottom；
Filter packing is equipped in described filler layer 203, the total filler volume of the filter packing is that described filler layer 203 is filled out
The 70-90% of Material product.
203 lower part of described filler layer is filler buffer layer 202；The height of the filler buffer layer 202 is described filler layer
203 10-30%.
203 side wall of packing layer of 202 top of the filler buffer layer is equipped with filter hole, but the side on 203 top of packing layer
Wall is closed, in order to enable water energy is enough to pass into more media filtrations, 202 lower part of filler buffer layer from lower part
Equipped with filter hole.
The secondary filter component 201 is followed successively by filtering meshes 2011 from top to bottom, upper secondary filter layer 2012, stands
Layer 2013, accurate packing layer 2014, lower secondary filter layer 2015, lower filtering meshes 2016；And pass through between adjacent two layers
Separation net separates.
Wherein upper filtering meshes 2011 and lower filtering meshes 2016 play separation buffer action, and one is formed between two
Space is for accommodating other filter layers etc.；And upper secondary filter layer 2012, standing layer 2013, accurate packing layer 2014, lower essence
Close filter layer 2015 also has a receiving container to be isolated between adjacent layer；
2012 water supply of standing layer one smoothly excessively, is further sunk so that passing through the filtered water energy in lower section in secondary stop
It forms sediment, so that top filter effect is more preferable；
Several filtering lines 2000 are equipped in the upper secondary filter layer 2012 and lower secondary filter layer 2015；The filtering line
About 2000 extensions are connected to two neighbouring separation nets.
Spacing is 0.1-1mm between the filtering line 2000 of the upper secondary filter layer 2012；The lower secondary filter layer
Spacing between 2015 filtering line 2000 is 0.1-2mm.Bulky grain is first intercepted or is separated by lower secondary filter layer 2015, so
Afterwards by the accurate further filtering of packing layer 2014, further little particle is filtered finally by upper secondary filter layer 2012；
Filler rate in the precision packing layer 2014 is that 95-100% can be filtered so that the packing layer is more closely knit
Fall more short grained impurity；
Filter packing density in described filler layer 203 is less than 0.9g/cm3, can float in water, thus filtering
When, enable filter packing to be deposited in 203 top of packing layer under buoyancy, forms closely knit filter packing；It is described net
Water layer 22 is equipped with intake.
The quantity of the interior bucket 20 is one or more；The interior bucket 20 and 10 detachable connection of said tub.It is equipped with
Multiple is the work in order to do not influence in backwash process this device, guarantees that remaining can be just when one of cleaning
Often work；
30 bottom of water-insulating cover is equipped with aerator；The aeration tube of the aerator is located at the filter assemblies 21
In, and the two is arranged in the same direction.It when needing to clean, is drained by bottom mud discharging mouth 62, aerator is aerated in bottom, wherein one
Portion gas enters packing layer 203 from 202 bottom of layer and upsets the filler in packing layer 203 from changing, and enables impurity therein
Enough as downward water flow leaves packing layer 203；Aeration tube gos deep into filter assemblies 21 simultaneously, further makes to fill out from being wherein aerated
Filler is upset in the bed of material 203.
The working principle of the utility model are as follows:
Sewage enters from water inlet layer 40, then flows downward, by settling zone 50；It is some when sewage flows through settling zone 50
Large granular impurity precipitates；It is gushed in water reflux, into water-insulating cover 30；
After sewage enters in water-insulating cover 30, enter in packing layer 203 under the action of water pressure, first passes through the filtering of packing layer 203
Then it is rushed to filter assemblies 201 on, finally reaches in water purification layer 20；
After the water in water purification layer 20 reaches to a certain degree, pulled water out by intake；
Equipment after a period of use, can stop injecting in sewage, then sewage is discharged by mud discharging mouth 62；It is draining
In the process, the filler in packing layer 203 loosens, so that impurity flows downward with water；More just by aerator aeration simultaneously
It is impacted in by the impurity in filler；
Inside can also be washed away by aerator water flowing；Or from water purification layer 22 pass downwardly through back purge system into
Row rinses, the structure of back purge system uses existing common technology, all backwashing functions that is able to achieve.
Those skilled in the art can define, in the situation of the overall spirit and design that do not depart from the utility model
Under, the various modifications for above embodiments can be made.It each falls within the protection scope of the utility model.This is practical new
The protection scheme of type is subject to the utility model appended claims.
