The specific embodiment
Self-cleaning efficient water filter shown in Figure 1 mainly is made up of tank body 1, cartridge filter 2 and self-stripping unit 3.Tank body 1 is combined by end socket 1-1, upper shell 1-2 and lower shell 1-3.Lower shell 1-3 is provided with inlet N1, and upper shell 1-2 is provided with liquid outlet N2.Separated by dividing plate 4 and cartridge filter 2 between inlet N1 and the liquid outlet N2.Specifically, dividing plate 4 is fixed on the apposition position of upper and lower cylindrical shell 1-2,1-3, and the nose end of three circle cartridge filters 2 is fixing likes that the other end is fixed on the apposition position of end socket 1-1 and upper shell 1-2 on the dividing plate 4.Self-stripping unit 3 comprises three layers of scum pipe 6 of pivot and drive motors 5 connecting shafts, and the lower end of scum pipe 6 is connected with the slag-drip opening 8 that magnetic valve 7 is housed, and the other end can align with the nozzle of cartridge filter 2 respectively.Control circuit in the self-stripping unit 3 as shown in Figure 2, microswitch WD and radial Position Control dish shown in Figure 3 form can perception scum pipe angular position sensing element.The Position Control dish is fixed in the rotating shaft of drive motors 5, and the distributing position of its radiation tooth is corresponding with the distributing position of cartridge filter 2, therefore when the mouth of pipe of scum pipe 3 aligns with the nozzle of cartridge filter 2, must have a radiation tooth to trigger microswitch WD.The relay on-off delay control circuit adopts Siemens's 200 series of PLC to constitute.0.4 mouthful of the signal input part of the output termination PLC of microswitch WD.The control output end 0.0 of PLC meets drive motors start and stop solenoid relay valve KM1, and its another delivery outlet 0.1 is by auxiliary reclay KA1 run in cinder notch power on/off magnet valve relay K M2 and KM3.SA in this circuit is a change-over switch, and when this switch was pushed auto state " 1 " and " 4 ", system was in auto state; When this switch was pushed manual position " 1 " and " 2 ", system was in manual state.Among Fig. 2, KM1 is used for controlling drive motors (Fig. 1 5), and KA1, KM2, KM3 are used for controlling magnetic valve (Fig. 1 7), KA2 is used for resetting of timing relay K T, and this time relay is used for timing working, and KP is a pressure difference switch, SB is a hand push button, and B is standby.
The input of PLC is connected to hand switch SB, timing control switch KT, pressure difference switch KP and backup circuit breaker B respectively for 0.0,0.1,0.2,0.3 mouthful, 9 liang of contacts of the differential pressure pickup of pressure difference switch KP are placed in the interior outside of cartridge filter 2 respectively, when cartridge filter 2 stops up, inside and outside pressure reduction rises, thereby sends pressure difference signal.Like this, make the anti-cleaning of present embodiment drive to take manually as the case may be, multiple modes such as timing controlled or pressure reduction control, thereby make the filter of present embodiment have more flexibility and adaptability.
Present embodiment can have following three kinds of states:
1. when needing manually to clean, by " SB ";
2. after the time, relay K T reached setting-up time, the KT closure of often making war;
3. reach when setting value, KP closure when pressure reduction between the import and export of system.
More than three kinds of situation systems can both enter automatic cleaning state, its course of work is: SB, KT, arbitrary group of closure of KP, PLC promptly has input, 0.0 of PLC output simultaneously, KM1 closure, drive motors rotation, drive Position Control dish shown in Figure 3 and rotate, the scum pipe 6 among Fig. 1 also rotates thereupon.When scum pipe 6 turned to cartridge filter 2 positions aligning, the radiation tooth of Position Control dish triggered microswitch WD, and this switch sends signal, and 0.4 of PLC has input, made former 0.0 output interruption, and 0.1 has output simultaneously.At this moment, the KM1 dispensing, the drive motors stall, scum pipe 6 also is parked in and cartridge filter 2 positions aligning.Meanwhile, 0.1 output makes the KA1 adhesive, and its normally opened contact closure makes the KM3 adhesive again, and slag-drip opening magnetic valve 7 is opened.In the case, because cartridge filter 2 is communicated with atmosphere through scum pipe, slag-drip opening 8, therefore produce pressure reduction in the tube, medium moment generation is flow backwards, be blocked in waste residue on the cartridge filter 2 from the inside back flush of cartridge filter 2 outer walls, it is discharged together with the reverse osmosis medium, reach desirable self-cleaning effect.After this, when the deslagging time reached setting value, 0.1 output of PLC was interrupted, and the KA1 dispensing causes the KM3 dispensing, and the KM2 adhesive, the deslagging closed electromagnetic valve.0.0 output signal of PLC repeats said process again.
When whole cleanings finished, 0.0 and 0.1 signal of PLC all interrupted, 0.2 output triggering signal, and KA2 short time closure, time relay KT resets, and system quits work, and above-mentioned three kinds of situations occur up to next time.
