Described siphon pipe top is double-layer hollow tubular construction, at the outer layer pipe of mid-way sealing double-layer hollow pipe, the extreme higher position of the inner layer pipe of double-layer hollow pipe is lower than the warning water level of water collector, between outer layer pipe top to the water purifying chamber of double-layer hollow pipe, be provided with syphon trap, between the bottom of the outer layer pipe of double-layer hollow pipe and straining chamber top, be provided with communicating pipe.
Access ramp is formed between the two-layer filler in described former water precipitation pond.
The utility model adopts a kind of automatic back-washing filtration unit designed by technique scheme, by increasing the integral parts such as former water precipitation pond, water collector, filtered water reservoir, siphon pipe on the basis of existing former water supply line, realize the automatic operation of former water precipitation, filtration, reach and remove the effect that suspended substance improves water quality.
Accompanying drawing explanation
Fig. 1 represents the structural representation of a kind of automatic back-washing filtration unit of the utility model.
Embodiment
Illustrate below in conjunction with the structure of accompanying drawing to a kind of automatic back-washing filtration unit of the utility model.
See Fig. 1, a kind of automatic back-washing filtration unit of the utility model, comprise raw water pipeline, raw water pipeline is provided with raw water pump 5, raw water pipeline is established former water precipitation pond, wherein, the bottom in former water precipitation pond is divided into the settling chamber 7 of intake chamber 4 and band blow-off pipe 6 by grid, grid is provided with two-layer filler 8,10, the two-layer filler 8 in former water precipitation pond, forms access ramp 9 between 10, establish water collector 12 on the top in former water precipitation pond, water collector 12 is communicated with former water precipitation pond by the multiple tracks zig-zag spillway of upper end, former water precipitation pond.Water collector 12 is connected by outfall sewer 13 with the filtering basin on side, former water precipitation pond, filtering basin top, sidepiece are closed, filtering basin bottom is straining chamber 3, top is the water purifying chamber 14 of band water outlet 11, be equiped with multiple filter cap in straining chamber 3, filter cap is equipped with hard coal, crosses the filter material 2 of the variable grains such as filter sand.Be connected with siphon pipe 15 in the outside of water purifying chamber 14, siphon pipe 15 the other end connects draining trench 1.Siphon pipe 15 top of the present utility model is double-layer hollow tubular construction, at the outer layer pipe of mid-way sealing double-layer hollow pipe, the extreme higher position of the inner layer pipe of double-layer hollow pipe is lower than the warning water level of water collector, between outer layer pipe top to the water purifying chamber of double-layer hollow pipe, be provided with syphon trap, between the bottom of the outer layer pipe of double-layer hollow pipe and straining chamber top, be provided with communicating pipe 16.Said structure forms strainer of the present utility model.
The utility model is before Yuan Shui enters the intake chamber 4 in former water precipitation pond, and in former water, add appropriate flocculation agent by tube mixer by flocculation agent chemicals dosing plant, former water enters intake chamber 4 after adding flocculation agent.Former water crosses midfeather after being full of intake chamber 4, is full of settling chamber 7, and the raising along with water level is progressively full of packing layer and arrives the top in former water precipitation pond, is confluxed in water collector 12 by zig-zag spillway.The Main Function of the utility model packing layer is stationary flow, former water is made to form stable laminar flow regime in whole settling tank, and make the impurity in water form flocks under the effect of flocculation agent and imported in settling chamber 7 by the access ramp 9 of filler, and discharged by blow-off pipe 6.Water in water collector 12 enters the top of filtering basin by the outfall sewer 13 that its underpart is installed.When the impurities accumulation on filter material 2 to a certain extent after, filter water resistance progressively to increase, hydraulic pressure on filter material 2 increases, filtration chamber's pressure improves, the former water section that water collector 12 flows down no longer passes through filter material, but tube space outside the top being entered siphon pipe 15 by the communicating pipe 16 on straining chamber 3 top, and progressively discharge the air in siphon pipe.When impurities accumulation on filter material 2 is to time maximum, filter material 2 not after water, the water that water collector 12 gets off all by communicating pipe on straining chamber 3 top to the skin of siphon pipe 15, after exceeding the height of inner tube, flow into draining trench 1 by interior pipe.In this process, air in siphon pipe 15 is excluded, siphon pipe forms siphonic effect, and make the water on straining chamber 3 top be entered draining trench 1 by siphon pipe 15 sucking-off, the pressure on straining chamber 3 top sharply reduces, the ordinary water-level of water purifying chamber 14 is water outlet position, the pressure of the pressure ultra-filtration hydroecium 3 of such water purifying chamber 14, water purification can pass through filter cap, filter material 2, by siphon pipe 15 sucking-off, form backwash, remove the depositing contaminants on filter material 2 by backwash.When the water level of intake chamber 4 is down to syphon trap position, siphon pipe 15 top starts into air, and siphonic effect stops, on filter material 2, impurity is also complete by complete backwash, and the resistance drop of filtering layer is low to moderate normally, returns to filtration condition, complete whole backwash process, and automatically restore to filtration condition.
Strainer of the present utility model can realize automatic back-washing in operational process, automatically resumes operation, and effluent quality can reach certain standard, plays the object improving water quality.
