Detailed description of the invention
In order to feature of the present invention can be made more clear, disclose the specific embodiment of the present invention below with reference to accompanying drawing.
Self-driven water filter of the present invention has structure as shown in Figure 1, in upper shell 5 and the fastening filter chamber of lower house 6, net-filter assembly 10, blowdown breeches pipe 15 and micro impeller 4 is housed; Wherein water inlet pipe 1 is positioned at lower house 6 bottom and lower than the position of micro impeller 4, outlet pipe 2 be positioned at lower house 6 top and facing to the position of net-filter assembly 10.
Below with reference to Fig. 1-Fig. 3, net-filter assembly 10 is fixed in lower house 6, comprise gland 102, inside and outside two coil unit filter screens 103 and chassis 101, chassis 101 there is two circles water hole as shown in Figure 2, inside and outside two coil unit filter screens 103 are inserted in the groove of two circle water holes, the upper end of inside and outside two coil unit filter screens 103 is buckled with gland 102, can be bolted into an entirety between gland 102 and chassis 101.And in order to ensure sealing, filter screen and gland 102, between filter screen and chassis 101, also seal washer can be housed.Inside and outside two coil unit filter screens 103 are clamped between gland 102 and chassis 101, are fixed in the respective through hole on chassis 101 to make inside and outside two coil unit filter screens 103; The cross section of two circle water holes on chassis 101 can be various rational shapes, as circle, polygon etc.
Below with reference to Fig. 1, Fig. 4 and Fig. 5, blowdown breeches pipe 15 is positioned at the below of net-filter assembly 10, and it comprises fixed support 151, the thrust housing 153 in lower nozzle 152, two-arm and two-arm, spring 154 and U-shaped sealing ring 155.The two-arm of blowdown breeches pipe 15 is in " Y " shape, and the two ends centre-to-centre spacing of arm is not etc.U-shaped sealing ring 155 is between thrust housing 153 and upper orifice, the difference seat of two ends up and down of spring 154 is between thrust housing 153 and the boss of orifice outlet, thus make the upper surface of the thrust housing 153 in blowdown breeches pipe 15 two-arm prop up chassis 101, thrust housing 153 suitable for reading relative with two of chassis 101 circle water holes respectively, aperture is identical.Fixed support 151 is positioned on the external rotation of breeches pipe, and the lower end of its upper end and trunnion shaft 9 is rigidly connected; Lower nozzle 152 is connected with blow-off pipe 3 bearing, and micro impeller 4 is fastened on lower nozzle 152.
Like this, when " Y " shape blowdown breeches pipe 15 rotates, its two-arm thrust housing 153 upper surface is then close to filter screen chassis 101 and is done circumferential fricting movement, two mouths of pipe above its two-arm at the same time just to an interior coil unit filter screen and/or an outer coil unit filter screen, and can only create the chance of backflow flushing for it.Suppose that inner ring has M unit filter screen, there is N number of unit filter screen outer ring, and wherein only have at most 2 unit filter screens in flushing, all the other M+N-2 unit filter screens are still carrying out normal filtration work.Operating self-driven water filter is only accounted for 2/ (M+N) of work screen area by the screen area of cleaning, reduce by the ratio of the area of cleaning filter screen with work screen area, thus reduce cleaning amount and water consumption of removing contamination, also reduce the water pressure fluctuations amplitude of water filter outlet pipe 2 when clear blowdown of on-line operation, so the stability that water filter runs can be ensured.
