Description
Technical field
The utility model belongs to biological slow filter field, and in particular to a kind of biological slow filtering device with back purge system.
Background technology
At present, the slow filter of known biology is made up of plant running shell and internal different particle diameter filler, passes through dress
Impurity, suspension and the chemical composition contained in the filler filter water of inside is put, reaches the effect of purified water, device is in operation
Reduce harmful components to chemical degradation by the retention absorption of different-grain diameter filler and microorganism and reach drinkable level, the dress
Putting extremely has the popularization being adapted in the processing of small rural Decentralized drinking water.
But the retention absorption principle due to device inner stuffing in itself, device is when operation reaches three to six months, carefully
The silt of particle diameter filler retention, impurity, suspension etc. can gradual deposition, the table of biomembrane can be directly overlie when excessive
Face, the microbial degradation effect of device is directly affected, causes clean-up effect to be deteriorated, the water quality of water outlet does not reach drinking water standard, is
People bring many unfavorable.
Therefore, need to be eluriated the small particle size filler on top when using biological slow filtering device, and clean out device
Interior impurity, suspension and chemical substance, traditional method are after biomembrane is salvaged, by original upper part 40-60cm's
Fine grain filler is transferred out of out of device, is eluriated, this method complex operation, it is also desirable to elutriation container in addition, especially
It is to be vulnerable to place limitation for biological slow filtering device, and carries out causing workload big during mobile inside and outside device of filler, wave
Take manpower and time, it is extremely inconvenient.
Utility model content
For the deficiency of existing biological slow filtering device cleaning technique, the purpose of this utility model is to propose a kind of carry instead

The back purge system includes backwash shell, water inlet pipe and apopore, and the backwash shell is located at fine grain
The intersection of layer and coarse grain footpath layer, described water inlet pipe one end are fixed on backwash cover top portion, and other end break-through fine grain layer prolongs
Extend above biological slow filter filler housing；The side wall of the backwash shell has been evenly arranged four apopores；
Water distribution orifice plate is provided with below the back purge system, multiple water distributing pores have been evenly arranged on the water distribution orifice plate.
It is further that the diameter of the water distributing pore is less than the diameter in coarse grain footpath；Avoid the pressure water when being backwashed
The filler of greater particle size is carried into punching to the upper strata of the biological slow filtering device, ensure that the filter effect of the script of the device.
It is further that the slow filter filler housing sidewall of biology is provided with spillway hole, and the spillway hole is located at fine grain layer
Top, after backwash, the water with suspension and impurity from spillway hole discharge.
It is further that the distance of the spillway hole and fine grain layer is 20~30cm；For in biological slow filter filler housing
The upset of portion's filler, which is eluriated, provides enough spaces.
Further that the slow filter filler housing bottom side wall of biology is provided with delivery port, the device in normal use,
Discharged after water filtration by delivery port for people to use.
The beneficial effects of the utility model are：
The utility model effectively can not only easily eluriate filler, reach effectively cleaning purpose, and can be conveniently direct
Ground is rinsed in device, and cleaning dynamics to filler are increased using backwash, by bottom even transverse direction surrounding water outlet,
The uniformity of flushing is also ensure that, the material such as impurity, suspension and chemical composition for being easy to preferably dispose in filler, also may be used
Directly avoid silt from blocking the situation of delivery port, ensure that back purge system can be used for multiple times；Water distribution orifice plate can not only backwash
Device provides horizontal positioned condition, can also separate fine grain and coarse grain footpath, avoid unstable fluidised form from carrying coarse grain footpath
Into fine grain layer, mixing for filler is caused, influences the effect of filtering；And do not need additional other elutriation container or eluriate dress
Put, greatly reduce workload, saved time and human cost；Meanwhile back purge system of the present utility model is directly pacified
Put inside biological slow filter filler shell, greatly save installing space, be extremely applicable with biological slow filtering device for small home；This
It is simple to operate when utility model is cleaned inside to the slow filter filler shell of biology, there is stronger applicability.

Embodiment
In order that the purpose, technical scheme and advantage of utility model are clearer, below in conjunction with the accompanying drawings to the utility model
It is further elaborated.
In the present embodiment, as shown in Figures 1 to 3, a kind of biological slow filtering device with back purge system, the biology are filtered slowly
Device includes the slow filter filler housing 1 of biology, and the slow inside of filter filler housing 1 of biology is provided with slow filter membrane 2, fine grain layer 3, coarse grain
Footpath layer 4 and back purge system；The back purge system includes backwash shell 6, water inlet pipe 5 and apopore 7, and preferably backwash is outer
A diameter of 90mm of shell 6, a height of 40mm, the caliber of water inlet pipe 5 is 16mm, and the bore of apopore 7 is 32mm, the backwash
Shell 6 is located at the intersection of fine grain layer 3 and coarse grain footpath layer 4, and described one end of water inlet pipe 5 is fixed on the top of backwash shell 6, separately
One end break-through fine grain layer 3 extends to the biological slow top of filter filler housing 1；The side wall of the backwash shell 6 has been evenly arranged
Four apopores 7, and four apopores 7 are respectively positioned at four sides of backwash shell 6；Water distribution is provided with below the back purge system
Orifice plate 8, the 8 a diameter of 110mm for being evenly arranged multiple water distributing pores, preferably water distribution orifice plate 8, thickness are on the water distribution orifice plate
10mm。
As prioritization scheme of the present utility model, the diameter of the water distributing pore is less than the diameter in coarse grain footpath；Avoid carrying out
The filler of greater particle size is carried punching to the upper strata of the biological slow filtering device by pressure water during backwash, ensure that the script of the device
Filter effect.
As prioritization scheme of the present utility model, the slow side wall of filter filler housing 1 of biology is provided with spillway hole 9, described to overflow
Water hole 9 is located at the top of fine grain layer 3, and after backwash, the water for carrying various impurity is discharged from spillway hole.
As prioritization scheme of the present utility model, the distance of the spillway hole 9 and fine grain layer 3 is 20~30cm；Make a living
The upset elutriation that thing filters filler enclosure interior filler slowly provides enough spaces.
