Technical field
The invention belongs to sewage treatment field more particularly to a kind of anti-blocking filtering equipment and working method.
Background technology
In urban sanitation work, need periodically to remove rubbish, the sludge etc. in sewer, to ensure that sewer is unobstructed.
With the high speed development of China's urban construction, the length of city sewer also increases rapidly, and the dredging work of sewer becomes to get over
Come heavier.The complicated component of sewage sludge also contains a large amount of organic matter, difficult to degrade in addition to containing a large amount of moisture
The ingredients such as organic matter, various trace elements, pathogenic microorganism and parasitic ovum, heavy metal and salt, the big, ingredient by these yield
Complicated urban sewer sludge is innoxious, recycling, it has also become new difficult point in comprehensive environmental improvement work is newly chosen
War.
In traditional wastewater processing system, the supernatant of sedimentation basin and heavy mud act as can not lack part, while its occupy it is big
The place of area directly increases the investment of manufacturer, and fixed design water determines that it cannot receive the too big wave of water
Dynamic, the splashing of the sludge flocculating effect that rises and intake also directly affects the water quality of water outlet.
Existing filter plant generally requires manufacture pressure difference, and manufactures pressure difference and then need to consume the more energy.Filtering dress
The problem of being easy to happen plugged filter is set, excessive impurity is easy that hole plug will be filtered, to influence filter effect；It is existing
Solution technology can't solve blockage problem well, and operation difficulty is big, cause to filter cost raising.
Existing technology specific aim is insufficient, cannot accomplish to carry out distribution filtering to the mud of variable grain size, cause
Filter device short life, filter core are easily damaged.Or device structure is complicated, use cost is high.Meanwhile existing equipment floor space
Greatly, energy consumption is big.

Description of the drawings
Fig. 1 is a kind of structural schematic diagram of the present invention；
Fig. 2 is another structural schematic diagram of the present invention.
In figure：1 filtering ponds, 21 water inlets, 30 flow directions separate cover, 31 collecting channels, 300 flow data feedback channels, 301 flows
Down going channel, 40 filters, 50 buffering areas, 60 sludge collecting regions, 61 mud discharging mouths.
Specific implementation mode
Invention is further explained below in conjunction with the accompanying drawings：
A kind of anti-blocking filtering pond, including filtering ponds 1；Filtering ponds 1 are internally provided with flow direction and separate cover 30；
It is flow down going channel 301,301 top of flow down going channel that flow direction, which separates cover 30 and the clearance space of filtering ponds 1,
Equipped with water inlet 21；
Flow direction, which separates, is equipped with filter 40 in cover 30, flow direction separates 30 bottoms of cover and is equipped with opening；Separate cover 30 side wall with
The clearance space of filter 40 is flow data feedback channel 300；
40 inside of filter is collecting channel 31, and collecting channel 31 is communicated by water producing pipe 310 with the external world of filtering ponds 1；
1 bottom of filtering ponds is sludge collecting region 60, and 60 bottom of sludge collecting region offers mud discharging mouth 61；
40 lower section of filter is equipped with distribution device.
Flow direction, which separates, is equipped with buffering area 50 between cover 30 and sludge collecting region 60.
Distribution device is identical as the external world of filtering ponds 1 by tracheae.
The setting height of water inlet 21 is more than water producing pipe 310, and the two difference in height is greater than or equal to 0.5m.
Filter 40 is not secured to flow direction and separates cover 30, and flow direction separates the only bottom of cover 30 and is equipped with opening.
Filter 40 is granular pattern, is several filtering particles inside particle type filter, flow passes through the seam between particle
Gap, and impurity can not pass completely through intergranular gap since volume is larger and be detached with flow, be rushed by distribution device bubble
It hits and makes it easier to reset.
The collecting channel 31 is catchmented with what the water producing pipe 310 was connected to alternatively, separating to be equipped with above cover 30 in flow direction
Chamber 11 can also impact the impurity in filter 40 by 310 air inlet of water producing pipe after the completion of filtering；Water collection chamber 11 and institute
It is intake tunnel 12 to state 1 inner wall clearance space of filtering ponds, and the intake tunnel 12 is connected to the water inlet 21 and the filtering ponds 1
The external world, flow initially enter intake tunnel 12 after entering filtering ponds 1, then flow downward along clearance space, pass through water inlet 21
Continue to flow downward.
A kind of working method for anti-blocking filtering pond specifically includes following steps：
A. water inlet 21 and water producing pipe 310 are opened, mud discharging mouth 61 is closed；
B. it is intake by water inlet 21, flow reaches collecting channel 31 after filter 40；
C. filtering ponds 1 are left from water producing pipe 310 by pressure difference；
D. water inlet 21 and water producing pipe 310 are closed；
E. it is ventilated to distribution device by tracheae, meanwhile, open mud discharging mouth 61.
The present invention a kind of working method be：
Mud discharging mouth 61 to be closed, is intake by water inlet 21, flow is flowed downward by flow down going channel 301, due to
The inertia of impurities in water, when flowing to buffering area 50 under elementary stream, the larger impurity inertia of particle is larger, can pass through buffering area 50
Continue to sink, then sinks to sludge collecting region 60；And the smaller impurity of particle can be flowed up with water flowing, reach filtering
40 outside of device, partly enters flow data feedback channel 300, and flow passes through filter 40, the impurity of smaller particle to be hindered by filter 40
It blocks, clear water enters collecting channel 31, because of the presence of pressure difference, water one in collecting channel 31 is semi-direct to be left from water producing pipe 310
Filtering ponds.
After the completion of filtering, then water inlet 21 and water producing pipe 310 are closed.
Mud discharging mouth 61 is opened, the sludge in sludge collecting region 60 is directly discharged from mud discharging mouth 61.It is given simultaneously by tracheae
Distribution device is ventilated；Water level decreasing in filtering ponds 1 is fixedly connected since filter 40 does not separate cover 30 with flow direction, uses
Mode of the floatation suspension in water, therefore, filter 1 can decline with water level decreasing.There is filter 1 in the shaking of water level
The effect cleansed can wash away the impurity part adhered to thereon；The water that the distribution device outlet of 1 lower section of filter generates
Bubble, bubble to constantly on gush, filter is washed away, further the impurity in filter 1 is washed away, impurity is made to be mixed into again
In water, flowed out from mud discharging mouth 61 with flow.
Small filtering particle is used in filter 40, during water shakes and bubble washes away, small mistake
Particle is filtered to be easier, by impact displacement, particle resetting will to be filtered in filter 40, to the sludge quilt being more convenient in particle gap
It washes away out, be then discharged from mud discharging mouth 61 with flow.
" upper and lower " herein is reference with orientation in Fig. 1, is for, convenient for statement, not having other and special containing
Justice.The extraneous of filtering ponds refers to filtering ponds exterior space, the inside for distinguishing over filtering ponds.
In addition, the invention is not limited in the above embodiments, as long as it reaches the present invention's with essentially identical means
Technique effect should all belong to the scope of protection of the present invention.
