Description

Reversely-washing divides bucket efficient household water filter

The utility model relates to a kind of quality purifying device for water, and particularly a kind of reversely-washing divides bucket efficient household water filter.

The water purifier of Chu Shouing is of a great variety in the market, and it filters, scavenging material all is a special-purpose filter core of making definite shape, and what have can not clean, though cleaning of having, cumbersome, also can influence decontamination effect improving after the cleaning sometimes.Because the filtration, purification material is easy cleaning not, many users can not clean on time, have directly influenced the decontamination effect improving and the work-ing life of water purifier.In addition, special-purpose filter core need regularly replace, but because sample of producer of shape of filter core, versatility is not strong, can't buy former model filter core as the user, and water purifier has just become refuse.At present, still find no and the same or analogous product of the utility model.

The purpose of this utility model is to provide a kind of filtration, purification material to divide bucket in bulk, has the backwash function, and the filtration, purification material cleans and change all the efficient household water filter of reversely-washing branch bucket very easily.

Technical solution of the present utility model is: packing particulate filter material, adsorption cleaning material and hollow fiber ultrafiltration membrane in filter vat, purification bucket and the ultrafiltration bucket, the lower end of filter vat is connected with a purification bucket lower end, purifying bucket is communicated with the ultrafiltration bucket in the upper end, be provided with the backwash transforming valve between the last water-in of filter vat and water inlet pipe, the water-in of backwash transforming valve is connected with water inlet pipe, two water outlets are communicated with the following water-in of last water-in and purification bucket respectively, and the backwash transforming valve also is provided with sewage draining exit; Be provided with spool in the backwash transforming valve, spool is reverse frustoconic, is processed with twice arc guiding gutter on it, and the bottom of spool is provided with change lever.

Shell is provided with filter water faucet and ultrafiltration water nozzle, and filter water faucet is communicated with ultrafiltration barrel rim hole by flexible pipe, and the ultrafiltration water nozzle is connected with ultrafiltration bucket mesopore by flexible pipe.

The utility model structure design novelty is skillfully constructed: adopt unit block formula structure, filtration, purification and ultrafiltration divide bucket to realize that filtration, purification material list bucket is in bulk, and the Shi Buxu that reloads changes part, have solved filter core and have changed the relatively problem of difficulty; Owing to set up the backwash transforming valve, can filtration, purification material automatic back-washing be cleaned easily, improved decontamination effect improving and work-ing life greatly.The utility model can effectively be removed impurity in the water, fouling product and organism peculiar smell, and kill bacteria has been improved people's drinking-water quality.

Below in conjunction with accompanying drawing and most preferred embodiment content of the present utility model is further elaborated.

Fig. 1 is that structure master of the present utility model looks synoptic diagram;

Fig. 2 is a side-looking structure sectional view of the present utility model;

Fig. 3 is the structural representation of backwash transforming valve;

Fig. 4, Fig. 5 are respectively the view of backwash transforming valve when purifying with backwash.

With reference to accompanying drawing, the utility model by filter vat 1, purify bucket 2, ultrafiltration bucket 3 and shell 4, base plate 8 is formed, in bulk in the filter vat 1 have the particulate filter material to be used for removing water fouling product, impurity, its lower end is communicated with the lower end of flexible pipe and purification barrels 2; In bulk in the purification bucket 2 have the adsorption cleaning material to be used to remove the organism peculiar smell, and the upper end that purifies bucket 2 is connected with flexible pipe with the upper end of ultrafiltration bucket 3; Hollow fiber ultrafiltration membrane 33 is housed in the ultrafiltration bucket 3, play kill bacteria and action of microorganisms, the lower end of ultrafiltration bucket 3 be provided with ultrafiltration barrel rim hole 31 and ultrafiltration bucket mesopore 32, two holes by flexible pipe respectively be fixed on shell 4 on filter water faucet 41 and ultrafiltration water nozzle 42 be connected.Base plate 8 is provided with installs suspension member 81 and retaining clip 82, is respectively applied for to be fixed on the wall water purifier and fixing single tub assembly.5 of water-in 11 and water inlet pipes have additional backwash transforming valve 6 on filter vat 1, this valve is provided with four mouths: water-in 61 is connected with water inlet pipe 5, water outlet 62,63 is communicated with the following water-in 21 of last water-in 11 and purification bucket 2 respectively, and sewage draining exit 64 is opened on sewage draining exit 43 places on the shell 4; Be provided with spool 7 in the backwash transforming valve 6, spool 7 is reverse frustoconic, is processed with arc guiding gutter 71,72 on it, and the bottom of spool 7 is provided with the change lever 65 that is used for rotational valve core.

Working process of the present utility model is as follows:

(the conversion spool is in position shown in Figure 4) spool 7 is sealed water outlet 63 during purification, tap water is entered in the backwash transforming valve by water-in 61 through water inlet pipe 5, flow out by water outlet 62 through arc guiding gutter 71, enter in the filter vat 1 from last water-in 11, this moment, current had a compaction force to filtrate from top to bottom, can strengthen the media filtration effect; The lower end of the water inherent filtration bucket 1 after the filtration enters and purifies in the bucket 2, through purifying after in upper end inflow ultrafiltration bucket 3.At this moment, if filter water faucet is opened, the ultrafiltration water nozzle is closed, and then water is flowed out by filter water faucet 41 through 31 places, ultrafiltration barrel rim hole; If filter water faucet is closed, the ultrafiltration water nozzle is opened, and then water passes the process ultrafiltration of hollow fiber ultrafiltration membrane wall after ultrafiltration bucket mesopore 32 is flowed out by ultrafiltration water nozzle 42.

During backwash with change lever 65 half-twists, make spool be in position shown in Figure 5, this moment, arc guiding gutter 71 was communicated with water-in 61 with water outlet 63, arc guiding gutter 72 is communicated with water outlet 62 with sewage draining exit 64, the current trend is: water is entered in the backwash transforming valve by water-in 61 from water inlet pipe 5, through arc guiding gutter 71, water outlet 63 oneself following water-ins 21 enter and purify in the bucket 2, and be connected by what purify bucket lower end and filter vat lower end that flexible pipe is counter to be flowed in the filter vat 1, this moment, current produced suspending power to filtrate from bottom to top, make it be in half suspended state, bump each other and realize cleaning filtrate with this.Sewage after the cleaning is back in the backwash transforming valve by water outlet 62 through last water-in 11, is discharged by sewage draining exit 64 through guiding gutter 72 again.
