Abstract
The utility model discloses a kind of, and the efficient sedimentation tank central transmission concentrator containing back purge system opens submersible sewage pump in the case where sludge blockage influences spoil disposal, and flow passes through two twenty percents 120 on counter-flushing pipeline circumference.The flow that circular hole sprays is diluted and stirs to the thickened sludge that hardened state is gradually presented in collection mud pit, and the sludge of blocking is made quickly to be discharged outside pond；Open and close of the PLC by time control back purge system can also be used, the sludge in collection mud pit is enable continuously, to be rapidly discharged.
Description
Technical field：
The utility model belongs to sewage treatment field, and in particular to a kind of efficient sedimentation tank center containing back purge system
Transmission thickener.
Background technology：
Efficient sedimentation tank central transmission concentrator is mainly used for scraping the thickened sludge in sewage treatment plant's efficient sedimentation tank
Collection is to pool aottom center collection mud pit, further to make sludge dewatering treatment.
Due to the Layout Problem of active sludge pipe and excess sludge pipe, currently on the market efficient sedimentation tank center driving concentration
Center scraper can be arranged in some with machine, and some are just not provided with center scraper to prevent from interfering with sludge pipe.Due to High-rate sedimentation
Pond sludge content is heavier, center collection mud pit sludge can be caused more and more denseer if being not provided with center scraper, easily form hardened state, from
And excess sludge blockage is caused, influence spoil disposal.
Invention content：
It is not easy that center scraper, sludge pipe easily blocking etc. is arranged for efficient sedimentation tank central transmission concentrator currently on the market
A series of problems, the utility model provide a kind of efficient sedimentation tank central transmission concentrator containing back purge system, can solve
Certainly above-mentioned technical problem.
In order to solve the above technical problems, the utility model devises a kind of efficient sedimentation tank center containing back purge system
Transmission thickener, including：Transmission device 1, main shaft 2, catch basin 3, blade member 4, scraping arm 5, flange shaft 6, kuppe 7, inclined tube 8
And back purge system 9.Being not provided with, center scraper bottom of pond collection mud pit sludge concentration is higher and higher, and gradually forms hardened state,
In the case of causing spoil disposal blockage, back purge system 9 is opened, starts submersible sewage pump e, while wafer type electrical ball valve b and non-return
Valve f is also opened, and pool inner water flows through suction line a and enters, and enters counter-flushing pipeline h by discharge line g, by its pipeline circumference
The circular hole opened sprays, and the sludge in collection mud pit is diluted and is stirred so that the sludge of blocking can quickly be discharged outside pond.
Compared with prior art, the utility model has the following advantages that：
1, it is convenient for arrangement, it is not necessary to consider whether to interfere with bottom of pond active sludge pipe and excess sludge pipe；
2, the same stirring action of center scraper can not only be played, moreover it is possible to the sludge in bottom of pond collection mud pit is diluted,
It is more convenient for blocking the discharge of sludge；
3, reach sludge by the open and close of time remote control back purge system using PLC and rapidly, continuously arrange
The effect gone out.
Description of the drawings：
Fig. 1 is the efficient sedimentation tank central transmission concentrator outline drawing containing back purge system；
Fig. 2 is back purge system layout drawing；
Fig. 3 is the fixation of counter-flushing pipeline 3 and trepanning layout drawing.
Wherein：1, transmission device 2, main shaft 3, catch basin 4,5 scraping arm 6 of blade member, flange shaft 7, lead
Stream cover 8, inclined tube 9, back purge system；
In back purge system 9：A, suction line b, wafer type electrical ball valve c, elastomer connector d, transition pipe
E, submersible sewage pump f, check-valves g, discharge line h, counter-flushing pipeline i, pipeline support.
Specific implementation mode：
Below in conjunction with the accompanying drawings, the optimal technical scheme of the utility model is described in detail：
Back purge system 9 is mainly by suction line a, wafer type electrical ball valve b, elastomer connector c, transition pipe d, submersible sewage pump
E, check-valves f, discharge line g, counter-flushing pipeline h and pipeline support i compositions, ground is exposed in the scenes discharge line g with pre-buried pipeline
The one end in face is welded, and counter-flushing pipeline h then stretches into one end welding in collection mud pit with pre-buried pipeline, and submersible sewage pump e passes through foundation bolt
Be fixed on the boss of ground, suction inlet one end is connect by bolt with transition pipe d, excessive pipeline d through elastomer connector c again with it is right
Clip electrical ball valve b is connected, and wafer type electrical ball valve b is connect with suction line a, and suction line a is extend into efficient sedimentation tank；
And its exit end is connect by bolt with check-valves f, check-valves f is connected with discharge line g again, and discharge line g is through built-in pipe
Road is connect with counter-flushing pipeline h, and counter-flushing pipeline h is rounded to be fixed on by pipeline support i on bottom of pond collection mud pit, in its circumference
On open two twenty percents 120.Circular hole, sludge blockage influence spoil disposal in the case of, open submersible sewage pump e, flow is by suction line a
Into, counter-flushing pipeline h is entered by discharge line g, by its circumference circular hole spray flow to collection mud pit in gradually present
The thickened sludge of hardened state is diluted and stirs, and the sludge of blocking is made quickly to be discharged outside pond；PLC can also be used and pass through the time
The open and close for controlling back purge system, enable the sludge in collection mud pit continuously, to be rapidly discharged.
