In each described unit filter layers, be all filled with granular filler, the top of each described unit filter layers arranges sand washing blast tube, the described permeable sand control separation net of the bottom of each described unit filter layers is obliquely installed, and on the described cartridge filter barrel of its lowest part, be provided with and inhale sand mouth, described suction sand mouth is communicated to the import of described transh pump after sand block valve and pump inlet valve;
The import of depositing sand filter described in described impurity delivery side of pump is communicated to; Described depositing on sand filter arranges sand suction pipe, the import to the described sand washing blast tube in each described unit filter layers through sandblast cross current after sand suction pipe valve; Described depositing is also provided with outlet of sewer on sand filter, described outlet of sewer is drawn two pipelines after outlet of sewer valve, the setting pot that one tunnel is communicated to, another road is also communicated to described sandblast water pipe through circulation pipe, and then is communicated to the import of the described sand washing blast tube in each described unit filter layers.
The pipeline of depositing the import of sand filter described in described impurity delivery side of pump is communicated to is provided with deposits sand filter imported valve.
Described sandblast cross current is provided with sand washing blast tube imported valve to the pipeline of the import of the described sand washing blast tube in each described unit filter layers.
Described suction sand mouth is communicated to the import of described transh pump successively after described sand block valve and described pump inlet valve.
Described water inlet cabin arranges dirt inlet, described in go out water tank water purification delivery port be set.
Described permeable sand control separation net is metal isolation net.
The online backwash technology of vertical cylinder type container granular filler filter mainly relies on: metal isolation net, sand washing blast tube, transh pump, deposit sand filter, sand block valve, sand suction pipe, sandblast water pipe composition, realize state back flush (online backwash) packing layer of not stopping transport at container; In online backwash process, filler and impurity dirt are discharged from the rear transh pump of crossing and clean and separate, and then enter and deposit sand filter cleaning, are then again distributed into packing layer by pipeloop; Therefore, filler particles can thoroughly be cleaned, thereby guarantees the active porosity of filler, and isolated impurity dirt can thoroughly be discharged simultaneously.
The beneficial effects of the utility model can be summarized as follows:
This technology of the utility model can guarantee that equipment carries out back flush in the situation that not stopping transport, and has avoided the impact to peripheral sewage disposal device; Pump drainage is crossed the mode of pump cleaning filler, makes filler obtain cleaning to greatest extent, has guaranteed that equipment can remain best filter effect, to guaranteeing that sewage disposal qualification rate has facilitation thoroughly.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Clearer for technical problem, technical scheme and beneficial effect that the utility model is solved, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
The online back washing device of a kind of vertical cylinder type container granular filler filter as shown in Figure 1, comprise cartridge filter 1, transh pump 2 and deposit sand filter 3, described cartridge filter 1 is vertically placed, described cartridge filter 1 comprises into water cabin 16, packing section 18 and go out water tank 17, the interior setting of described cartridge filter 1 is the permeable sand control separation net 4 of N layer at least, and N is more than or equal to 2 natural number; Described packing section 18 is divided at least N-1 unit filter layers 5 by the permeable sand control separation net 4 of described N layer; In each described unit filter layers 5, be all filled with granular filler, the top of each described unit filter layers 5 arranges sand washing blast tube 6, the described permeable sand control separation net 4 of the bottom of each described unit filter layers 5 is obliquely installed, and on described cartridge filter 1 barrel of its lowest part, be provided with and inhale sand mouth, described suction sand mouth is communicated to the import of described transh pump 2 after sand block valve 7 and pump inlet valve 8; Described in being communicated to, the outlet of described transh pump 2 deposits the import of sand filter 3; Described depositing on sand filter 3 arranges sand suction pipe 9, is communicated to the import of the described sand washing blast tube 6 in each described unit filter layers 5 after sand suction pipe valve 10 through sandblast water pipe 11; Described depositing is also provided with outlet of sewer on sand filter 3, described outlet of sewer is drawn two pipelines after outlet of sewer valve 12, the setting pot 13 that one tunnel is communicated to, another road is also communicated to described sandblast water pipe 11 through circulation pipe, and then is communicated to the import of the described sand washing blast tube 6 in each described unit filter layers 5.
