Description of drawings:
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed description.
Fig. 1 is the structural representation that the utility model recirculated water valveless water filter device improves the preferred implementation of structure.
Fig. 2 is that the utility model recirculated water valveless water filter device improves in the structure under auxiliary siphon pipe effect in the backwash tube liquid level variation sketch map that rises.
The specific embodiment
Among Fig. 1, the embodiment shown in Figure 2; A kind of recirculated water valveless water filter device improves structure; Comprise elevated tank 10 and oral siphon 11 and outlet pipe 12; The water route turnover of elevated tank 10 is seen shown in Fig. 1 direction of arrow, and circulating water strainer 30 and external circular treatment pipeline, on the bottom outlet pipe 12 of elevated tank 10 outlet pipes 12 access circulating water strainers 30, is provided with restricting orifice 20.Backwash tube 35 and auxiliary siphon pipe 36 are installed on the circulating water strainer 30; Backwash tube 35 is tilted to also from circulating water strainer 30 upper ends and extends in the blowdown tank 40 after the bending downwards; Auxiliary siphon pipe 36 connects and extends down in the blowdown tank 40 from the top end of backwash tube 35, has blowdown outlet 41 on the blowdown tank 40.The automatic terminator 33 of backwash is installed on the circulating water strainer 30, is connected with vacuum breaking pipe 34 on the automatic terminator 33 of backwash, vacuum breaking pipe 34 tail ends are connected with backwash tube 35.Have clear water output pipe 31 on the circulating water strainer 30, filter material layer 32 is installed in the circulating water strainer 30, auxiliary siphon pipe 36 locates to be provided with pressure backwash mouth 361 above leaning on blowdown tank 40, force backwash mouth 361 to be provided with air admission valve 37.Backwash tube 35 bottoms are provided with backwash forced adjustment device 38 in blowdown tank 40.
In the circulating water treatment process; Along with the carrying out of filtering, the increasing of the impurity that filtrate is held back in the circular water treating system, water increases through the resistance of filter material layer; And then the pressure differential that causes the filter material layer Inlet and outlet water needs to increase, and the result of its performance is exactly that the liquid level difference of filtering layer Inlet and outlet water increases.Because the water outlet liquid level is constant, maintain near the delivery port basically, so the liquid level of filter material layer water inlet raises, also be that backwash tube rising part middle water level raises.When water level rose to the auxiliary siphonal mouth of pipe, water flowed down from auxiliary siphon pipe, and the vacuum and the gas effect of holding under the arm of current that rely on descent waterflow in pipe, to form further make the increase of system vacuum degree, and backwash tedge water level further raises.Because auxiliary siphon pipe caliber very carefully causes its downflow flowing to be not enough to the water level that rises in the balance backwash tube, so liquid level can be crossed auxiliary siphon pipe continuation rising (seeing the variation signal direction of liquid level 50 among Fig. 2) in the backwash tube.Cross the backwash tube top and when falling, vacuum sharply increases in the pipe when the water in the tedge, the rising water column converges into one and goes out the mouth of pipe in falling water flow and the backwash tube, all takes away residual air in the pipe, forms the serial siphon current.At this moment, because the filtering layer upper pressure die-offs, the rightabout that impels the water in the backwash water tank following when filtering gets into the siphon tedge, and then the entering backwash tube drains, filter material layer thereby receive backwash.In flushing process, the water level in the backwash water tank descends gradually, when water level drops to the automatic terminator of backwash, and the siphon destructing tube mouth of pipe and atmosphere in the automatic terminator of backwash, siphon is destroyed, and flushing process finishes, and filtration restarts.
Although this paper has used terms such as bottom outlet pipe, restricting orifice, auxiliary siphon pipe, circulating water strainer, backwash tube, the automatic terminator of backwash, vacuum breaking pipe morely; But do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present invention more easily; It all is contrary with spirit of the present invention being construed to any additional restriction to them.
