Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
Embodiment 1:
As shown in Figure 1, described device by water inlet pipe 1, water intaking valve 2, the first sea water pump 3, first overflow valve 4, leather bag 5, water storage valve 6, bolt 7, upper end cover 8, sealing ring 9, filtration barrel body 10, filter core 11, outlet pipe 12, outlet valve 13, flow rate detector 14, blow-off pipe 15, blowoff valve 16, the second sea water pump 17, bottom end cover 18 and the second overflow valve 19 form.
The filter core 11 of annular is placed in filtration barrel body 10, and is fixed by upper end cover 8 and bottom end cover 18, with sealing ring sealing, component content chamber and outer cavity volume, wherein, content cavity is limited by circular filter core 11 inwall and upper end cover 8 and bottom end cover 18; Outer cavity volume is limited by filter core 11 outer wall and filtration barrel body 10 inwall and upper end cover 8 and bottom end cover 18.
Water inlet pipe 1 is connected with content cavity, is connected with water intaking valve 2 and the first sea water pump 3 in this inlet pipeline.The effect of water intaking valve 2 is the break-makes controlling inlet pipeline, and the effect of the first sea water pump 3 pumps into seawater to content cavity.
Outlet pipe 12 is connected with outer cavity volume, is connected with outlet valve 13 and flow rate detector 14 in this outlet pipeline.The effect of outlet valve 13 is the break-makes controlling outlet pipeline, and the effect of flow rate detector 14 is the flow velocity or the flow that detect fluid in water lines.Outlet pipe docks with in-situ study detecting instrument 20.
Blow-off pipe 15 is connected with content cavity, is connected with blowoff valve 16 and the second sea water pump 17 in this blowoff line.The effect of blowoff valve 16 is break-makes of control of sewage disposal pipeline, and the effect of the second sea water pump 17 is discharged by the water in content cavity.
Leather bag 5 is connected with outer cavity volume by water storage valve 6.The effect of leather bag 5 be water storage for carrying out backwash to filter core 11 and rinsing the water in device, the effect of water storage valve 6 controls being communicated with of leather bag 5 and water between outer cavity volume.
In addition, consider from security standpoint, content cavity and outer cavity volume are connected to the first overflow valve 4 that can intake and can the second overflow valve 19 of water outlet respectively.When the pressure in content cavity and external environment pressure difference are greater than the force value that overflow valve sets, seawater enters content cavity by the first overflow valve 4, and when the pressure of outer cavity volume and external environment pressure difference are greater than the force value that overflow valve sets, the water of outer cavity volume is discharged by the second overflow valve 19.
By filter by assembling shown in figure and after connecting with in-situ study detecting instrument 20, being first full of water by filter, comprising leather bag and be also filled with water, water pump and each valve closing, then lay together to operating position, ocean.Before operation, first filter carries out 3 self-cleanings, mainly the washing be previously full of in device is gone out with the seawater of original position.
After having cleaned, open water intaking valve 2, outlet valve 13, open the first sea water pump 3, carry out filtering and to in-situ study detecting instrument 20 sample introduction, in-situ study detecting instrument 20 is started working.
When the flow value finding in filter process that flow rate detector 14 shows is starkly lower than the metered flow of the first sea water pump 3, illustrate that filter core 11 may be blocked by particle, now, the break-off of in-situ study detecting instrument, carries out the self-cleaning of filter.First carry out filter-core back-flushing and wash operation, that is: filter cuts out the first sea water pump 3, closes water intaking valve 2 and outlet valve 13, open blowoff valve 16 and water storage valve 6, start the second sea water pump 17, now have water to flow to content cavity through filter core 11 from outer cavity volume, thus backwash is carried out to filter core.After the water of leather bag 5 storage exhausts, carry out the operation of leather bag water-filling, that is: close the second sea water pump 17, close blowoff valve 16, open water intaking valve 2, open the first sea water pump 3, to leather bag 5 water-filling.After leather bag 5 is full of water, close the first sea water pump 3, close water intaking valve 2.The filter-core back-flushing repeated above washes operation and leather bag water-filling operates 3-5 time, completes the self-cleaning of filter, closes water storage valve 6.
After filter self-cleaning completes, open water intaking valve 2, outlet valve 13, open the first sea water pump 3, proceed filter and to in-situ study detecting instrument 20 sample introduction, in-situ study detecting instrument 20 works on.Find in work that filter core blocks, then carry out filter self-cleaning as previously mentioned.
