A kind of swash plate flusher
Technical field
This utility model relates to a kind of cleaning device, particularly to for cleaning water conservancy and the swash plate of engineering of water treatment or oblique
The flusher of pipe sedimentation tank.
Background technology
Precipitation is the important step of mud-water separation in water treatment technology, and its operation conditions directly affects effluent quality, tradition
Horizontal sedimentation tank advantage be simple structure, safe and reliable, shortcoming is that floor space is big, and treatment effeciency is low, wants to reduce
Before filter, the turbidity of water will strengthen the length of sedimentation tank significantly.And this is opposed with human social theory
's.
Inclined-plate clarifying basin refers to be provided with the sedimentation tank of swash plate in settling zone.In flat flow or the precipitation of vertical sedimentation basin
Utilize the parallel pipe tilted or parallelpiped (sometimes may utilize honeycomb filler) to be divided into a series of shallow layer precipitating floor in district, located
The heavy mud with sedimentation of reason mutually moves in each precipitation shallow-layer and separates.According to its mutual direction of motion be divided into inverse (different) to
Stream, three kinds of different separate modes of concurrent and reverse flow.Between every two pieces of inclined paralled plates (or in parallel pipe) be equivalent to one the most shallow
Sedimentation tank.
But common inclined-plate clarifying basin has again easy deposition, surface easily to grow algae and the problem such as perforation spoil disposal is the most smooth.Need
The most clear pond is rinsed, and reduces because biomembrane overgrowing causes clogging.And this needs power-off to stop production, and the clear pond of draining, will shadow
Ring the process to sewage disposal.Cause the non-qualified discharge of sewage.And the mud on artificial flushing swash plate is also not susceptible to
Operation, and there is certain danger.

As the further improvement of such scheme, through-hole spacing adjacent on same described pipeline is 10~30cm.
As the further improvement of such scheme, described through-hole diameter is 1~3mm.
As the further improvement of such scheme, also including PLC automatic control switch board, described gas rushes control valve and controls with water punching
Valve is all electrically connected with PLC automatic control switch board.
As the further improvement of such scheme, also include that sludge bucket, described sludge bucket are positioned at the lower section of backwash pipe network.
As the further improvement of such scheme, bottom described sludge bucket, it is connected to discharge pipeline, equipped with certainly on described discharge pipeline
Dynamic mud valve.
As the further improvement of such scheme, described automatic mud removing valve is electrically connected with PLC automatic control switch board.
The beneficial effects of the utility model are: by connection at the online water inlet pipe network of backwash tube and air inlet pipe network, can
With according to on-the-spot actual demand, and rush control valve and rush control valve by controlling gas with water, make backwash pipe network uniformly go out air,
Water or water-gas combined work, the mud that will be attached on swash plate surface washes away totally.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is sectional view of the present utility model;
Fig. 2 is plane graph of the present utility model;
Fig. 3 is PLC automatic control switch board connection figure of the present utility model.
Detailed description of the invention
Swash plate flusher as shown in Figure 1-2 and inclined-plate clarifying basin, inclined-plate clarifying basin is built with swash plate support 8, tiltedly
Board mount 8 is provided with some swash plates 9, and above-mentioned swash plate 9 also can substitute with inclined tube.
Swash plate flusher includes air inlet pipe network 2, water inlet pipe network 3 and is positioned at the backwash pipe network 1 below swash plate 9.Enter
Gas pipe network 2, water inlet pipe network 3 all connect with backwash pipe network 1, and air inlet pipe network 2 rushes control valve 4, described water inlet pipe network 3 equipped with gas
On rush control valve 5 equipped with water, backwash pipe network 1 is provided with some split through holes 6, split through hole in the direction of vertical level
Mud bottom swash plate 9 and inclined-plate clarifying basin can be rinsed simultaneously, sky can be selected according to different field demands
Gas and water or water-gas combined work are rinsed.
Improving further, backwash pipe network 1 includes some pipelines being parallel to each other, and the parallel distance of adjacent channel is
20cm, through hole 6 is opened on each pipeline.
Improving further, every pair of through hole 6 spacing adjacent on same pipeline is 10cm.
Improve further, a diameter of 3mm of through hole 6.
Improve further, as it is shown on figure 3, swash plate flusher also includes PLC automatic control switch board 7, gas rush control valve 4 with
Water rushes control valve 5 and is all electrically connected with PLC automatic control switch board 7, can be by parameter set in advance by PLC programming input PLC
Automatic control switch board 7, makes inclined-plate clarifying basin automatically start swash plate flusher after running certain time.
Improving further, with reference to Fig. 1 and Fig. 2, be provided with sludge bucket in the bottom of inclined-plate clarifying basin, this sludge bucket 10 is positioned at
The lower section of backwash pipe network 1, for collecting the mud precipitated.
Improve further, be connected to discharge pipeline 11 bottom sludge bucket 10, equipped with automatic mud removing valve 12 on discharge pipeline 11, open
The mud collected can be discharged by automatic mud removing valve 12.
Improving further, with reference to Fig. 3, described automatic mud removing valve 11 is electrically connected with PLC automatic control switch board 7.
The operation principle of above-described embodiment is as follows:
Embodiment uses PLC automatic control switch board 7, and the parameter set according to PLC programming, when running one section with inclined-plate clarifying basin
As the setting value of startup swash plate flusher after between, or can set using every day, a couple of days or longer time as opening
The setting value of dynamic swash plate flusher.
After inclined-plate clarifying basin runs a period of time, PLC automatic control switch board 7 controls automatic mud removing valve 12 and starts, and swash plate sinks
Mud in pond, shallow lake is discharged by sludge bucket 10 and discharge pipeline 11, and after spoil disposal, automatic mud removing valve 12 cuts out, now swash plate
The liquid level of sedimentation tank declines, and according to pre-set program and on-the-spot practical situation, opens gas and rushes control valve 4 or water punching
Control valve 5 or two control valves are opened simultaneously, and after opening controlling valve, the through hole 6 on the backwash pipe network 1 bottom swash plate can be all
Even goes out sky gas and water or water-gas combined work, will be attached to swash plate and washes away totally, flushed with the mud on sludge bucket 10
Cheng Zhong, can select inclined-plate clarifying basin break-off according to backwash rate or continue to run with.
Additionally, it is possible to be operated with manual switches gas and rush control valve 4 and rush control valve 5 to realize the unlatching of swash plate flusher with water
With closedown, and carry out two control valves opening and closing control without PLC automatic control cabinet 7.
Certainly, this utility model is not limited to above-mentioned embodiment, and those of ordinary skill in the art are without prejudice to this
Also can make equivalent variations or replacement on the premise of spirit, modification or the replacement of these equivalents are all contained in the application right
In requirement limited range.
