flow detector

17,18, two top water outlets respectively are provided with a branch pipe, in two outlets of this branch pipe is respectively to establish C magnetic valve 19, C1 magnetic valve 20, D magnetic valve 21 and D1

magnetic valve

22, and 22 of C1 magnetic valve 20 and D1 magnetic valves are connected to water purification aqua storage tank 42 with water purification rising pipe 23, this water purification rising pipe set out another counterflush water pipe 24 in 23 minutes, be in series with a motor 41 on these counterflush water pipe 24 pipelines, be connected with respectively again to being provided with the branch pipe of C magnetic valve 19, form a complete water pipeline device by this with D magnetic valve 21.

Wherein, this tow filtrator 10, set two normal-open

electromagnetic valves

12,13 and the two closed type

magnetic valves

14,15 of 10a bottom branch pipe, habitual technical can be replaced by single three-way control valve certainly (scheme not have and illustrate).

Please join Fig. 4, above-mentioned four A, B, C, D

magnetic valve

12,13,19,21 all is the control of controlled circuit 30, pilot circuit 30 of the present utility model is that the single-chip of establishing sequence of control in one is constituted, two

flow detectors

17,18 respectively in order to detect tow filtrator 10, the aquifer yield of 10a, and A magnetic valve 12B magnetic valve 13, C1 magnetic valve 20 and D1 magnetic valve 22 are to be made as normally open, and A1 magnetic valve 14, B1 magnetic valve 15, C

magnetic valve

19 and 21 of the magnet valves in D village are made as normally off, this single-chip is its interior sequence of control system farmland dominant discharge detector 17 of mat then, 18 and A～D

magnetic valve

12,13,19,21, A1～D1

magnetic valve

14,15,20,22, when two groups of

flow detectors

17,18 flux detectings are for just often, and each magnetic valve keeps the unlatching of original setting or cuts out shape.

As shown in Figure 2, under normal situation, motor 40 is with in the former water water inlet pipe 11 of former water suction, import strainer 10 respectively through A magnetic valve 12 and the B magnetic valve 13 that is normally open, filter among the 10a, water purification after filtering then is directed in the water purification rising pipe 23 via the

flow detector

17,18 of top water outlet, imports water purification aqua storage tank 42 at last, and its water purification filters after the formality to emit via filter material chamber 44 extreme traces at last.

Please join Fig. 2, when handling purificating raw water work after after a while, blocked as the serious contamination of filter pulp of a strainer 10a inside wherein, pressure when former water will pass through filter pulp increases, and the flow detector 18 of water outlet will detect flow to be reduced, even so the time pilot circuit 30 B magnetic valves 13 skip to closing condition by normally open, B1 magnetic valve 15 skips to opened condition (being wastewater discharge pipe 16 and strainer 10a conducting) by normally off synchronously, skip to closing condition with seasonal D1 magnetic valve 22 by normally open, 21 of D magnetic valves skip to opened condition by normally off, so the former water that former water water inlet pipe 11 enters all imports in the strainers 10 via A magnetic valve 12, and motor 41 starts, with the water purification of water purification rising pipe 23 and the water purification in the part water purification aqua storage tank 42, extract and be directed to counterflush water pipe 24, the filter pulp of mat water purification counterflush strainer 10a inside, and make the sand and dust particulate of being detained on filter pulp, foul is got express developed out, make and carry particulate secretly, the waste water of foul imports wastewater storage tank 43 via the B1 magnetic valve of having opened 15 by wastewater discharge pipe 16, when pilot circuit 30 was set the flush time arrival that filter pulp can be cleaned, this D magnetic valve 21 and B1 magnetic valve 15 were with rebound normally off once again (being that wastewater discharge pipe 16 is not communicated with strainer 10a).

After strainer 10a counterflush is removed totally (about 5 ~ 8 second time), pilot circuit 30 is then with D1 magnetic valve 22 and B magnetic valve 13 rebound normally opens, make former water water inlet pipe 11 2 sides return extensive conducting, water purification rising pipe 23 is derived by water purification, is returned to the normal filtration operation situation of Fig. 1 again.Before take off when strainer 10a carries out counterflush and clean in the process, though the water purification in the water purification rising pipe 23 are started the back suction by motor 41,, still can utilize the water storages in the water purification aqua storage tank 42 and uninterruptedly reach the water outlet supply in final pure water inlet end place.

Moreover, please join Fig. 3, when the aquifer yield that detects another strainer 10 as the flow detector 17 of this pilot circuit 30 reduces, promptly represent strainer 10 wherein filter pulp reached serious contamination degree, A magnetic valve 12, C1 magnetic valve 20 skip to closing condition by normally open, A1

magnetic valve

14,19 of C magnetic valves skip to opened condition by normally off, and counterflush purifies wherein filter pulp mode and effect also with as mentioned above, and form the purifier of back-washing type.

Moreover, wastewater discharge pipe 16 is connected among the wastewater trough 43, wastewater trough 43 bottoms are provided with a mud discharging control valve 45, wastewater trough 43 tops are provided with a upflow tube 46, be provided with a float(ing)valve 47 on the upflow tube 46, therefore and upflow tube 46 is connected with former water water inlet pipe 11, is thrown into waste water in the wastewater trough 43 and can has a precipitating action, makes mud be derived by mud discharging control valve 45.Be provided with the filter material chamber 44 that an inside is filled with adsorption material again in water purification aqua storage tank 42 back segments again, make via the water purification after filtering and adsorb through adsorption material again, the metallic element that is difficult for filtering is adsorbed, and makes the water purifying water quality of discharge better.And the waste water after backwash generally is directly to emit, it is also quite surprising that its quantity discharged adds the General Logistics Department, so it is collected in the wastewater trough 43, make waste water through for some time post precipitation, with deposition of dirt contained in the waste water, the also controlled circuit 30 time openings control of this mud discharging control valve 45, mud discharging control valve 45 is closed after the drain time that single-chip 31 is set arrives; Also can sedimentary dirt be discharged by manually opened exhaust-control valve 45.Moreover when when sedimentary waste water height exceeds the height of float(ing)valve 47, this float(ing)valve 47 is just opened upflow tube 46 inlets automatically, and the waste water through post precipitation is mixed with former water again, enters filter once more, and reaches the effect of waste water decrement.

Via above-mentioned explanation for architectural feature of the present utility model, combination kenel and embodiment, be not difficult to find that the utility model has following several advantage by the structural design of uniqueness:

1, under normal circumstances, filtered water purification is stored to the water purification aqua storage tank, so wherein a filter oppositely rushes When washing, still have sufficient a large amount of water purification that use is provided.

2, the mode of employing to washing need do not changed filter pulp.

3, effectively reclaim waste water reuse, significantly reduce wastewater flow rate.

4, the water purification mouth is equipped with the filter material chamber of filling adsorption material, makes the water purification that leaches be subjected to adsorption material absorption metallic element once more, and has better effect.

In sum, quick opposite-washing type quality purifying device for water of the present utility model, eliminate the shortcoming that the typical filter device need regularly replace filter material, and a kind of zero consumptive material is provided, need change filtering element (cartridge), still to have a large amount of water purification when counterflush available, simultaneously can reduce wastewater flow rate, practical value is simplified, is had in its design, is suitable for the utilization on the industry, proposes patent application in accordance with the law.
