Fig. 2 is that the utility model filters the front view schematic diagram under the operating mode.
The specific embodiment
Below in conjunction with drawings and Examples structural principle of the present utility model and operation principle are further specified:
See figures.1.and.2, a kind of inflatable filter tank, comprise sewage water inlet pipe 1, be installed into water valve 2 on the sewage water inlet pipe 1, the outlet of sewage water inlet pipe 1 is connected with water inlet weir notch 3, water inlet weir notch 3 communicates with filter chamber 7 by being provided with into water weir plate 4 of one side, 7 bottoms, filter chamber are provided with backwash outlet pipe 6, backwash discharging valve 5 is installed on the backwash outlet pipe 6,7 inside, filter chamber are provided with filler chamber 14, be filled with filler 12 in the filler chamber 14, filler chamber 14 tops are equipped with covers perforated plate 9, be positioned at and cover perforated plate 9 both sides and be provided with cloth aquaporin 8, the soft elasticity of the arranged outside of filler chamber 14 filter tank outer wall 11, the outside of soft elasticity filter tank outer wall 11 is filter tank sidewall supplemental support 10 of thin-walled perforated plate configuration, filter tank sidewall supplemental support 10 is connected with an end of lower floor perforated plate 13, the other end of lower floor's perforated plate 13 is connected with soft elasticity filter tank outer wall 11, cloth aquaporin 8 belows are provided with backwash control valve 21, lower floor's perforation version 13 is arranged with aeration tube 22, filter chamber's 7 arranged outside have coupled logical backwash water channel 15, backwash water channel 15 be connected with the outlet canal 16 in the outside and between be provided with out sluice gate 18, the top of backwash water channel 15 is provided with backwash water inlet pipe 17, be provided with backwash water intaking valve 23 on the backwash water inlet pipe 17, bottom one side of outlet canal 16 is provided with outlet pipe 20, is provided with flowing water Valve 19 on the outlet pipe 20.
The specific embodiment of the present utility model is:
Filter under the operating mode, with reference to Fig. 2, water intaking valve 2, water inlet weir plate 4, go out sluice gate 18, flowing water Valve 19 is opened, backwash discharging valve 5, backwash water intaking valve 23, backwash control valve 21 are closed.Sewage is entered into water weir notch 3 by sewage water inlet pipe 1 through promoting, and injects filter chamber 7 by water inlet weir plate 4.Along with constantly entering of sewage, filter chamber's 7 liquid levels raise gradually, and the outer wall 11 interior outsides in soft elasticity filter tank form water-head, under the water pressure action, soft elasticity filter tank outer wall 11 is compressed, and the inner lightweight elastic filler 12 of filling of compression finally presents inner concavity shown in Figure 2.When filter chamber's 7 liquid levels were increased to the outer wall height of cloth aquaporin 8, sewage entered cloth aquaporin 8, and by on cover perforated plate 9 water distribution uniformities, enter filler chamber 14 and begin to filter.Sewage flow through the successively flexible filtrate 12 of lightweight, lower floor's perforated plate 13, backwash water channel 15 by filtering out sluice 18 rear final remittance outlet canals 16, flow out through outlet pipe.
Under the backwash operating mode, close water intaking valve 2, water inlet weir plate 4, go out sluice gate 18, flowing water Valve 19, open backwash outlet valve 5, the water in the filter chamber 7 is emitted through backwash outlet pipe 6, and water level reduces gradually.Under filtrate 12 Action of Gravity Fields, soft elasticity filter tank outer wall 11 expands and is outer gibbosity, and filler chamber's 14 cross sections increase, thus the filter material layer thickness reduction.Open the backwash water intaking valve 23 on the backwash water inlet pipe 17, open simultaneously the equipment such as blower fan that are connected with aeration tube 22, aeration tube 22 beginning aerations.Backwashing water flows into backwash water channel 15, passes lower floor's perforated plate 13 and enters filler chamber 14.Because the aeration effect, filtrate 12 is stirred, flushing, and the dirt impurity of holding back in the filter process is washed out.Open filter back washing control valve 21, backwashing sewage water flows out, and flows into backwash outlet pipe 6 through filter chamber 7 and enters the municipal wastewater pipeline.
Filter tank of the present utility model sidewall adopts soft elastic material, according to different operating mode demands, regulates the filter tank sidewall and is in indent/evagination state, and filter tank filler chamber cross-sectional area changes, thereby changes filtrate thickness.Particularly: filtration stage, controlled filter chamber water level is higher than filter tank body interior water level, under the pressure-acting of water-head, outer wall both sides, soft elasticity filter tank indent, filler chamber is compressed, its cross section is corresponding less, and filler reaches the design filter thickness, and sewage enters normal filtration after the main body of filter tank by water feed apparatus.The backwash stage, emptying filter chamber water, this moment, outer wall both sides, soft elasticity filter tank were outer gibbosity because the Action of Gravity Field of filler, and it is large that filler chamber's cross-sectional area becomes, and corresponding filtrate less thick is beneficial to the carrying out of backwash.
