The purpose of this utility model provides a kind of flow velocity that improves, precipitable and discharge dirt, but and the water purifier of filtering multiple harmful substances.

The purpose of this utility model realizes by following technical scheme, water purifier has shell, be connected in the top cover on the shell, be fixed in the filter cylinder at shell middle part, be attached to the outer filter screen of filter cylinder, gac in the filter cylinder, the felt material on gac top, water inlet pipe and rising pipe, it is characterized in that tangential being connected on the shell of said water inlet pipe, water shoot and water discharge valve are arranged on the bottom surface of said shell, between the bottom surface of said shell and the bottom surface of said filter screen the settling region that is not less than outer cover length 1/6 is arranged, between the medial surface of said shell and the outside surface of said filter screen the annular disengagement chamber is arranged, the diametric gap of this disengagement chamber is 1/10～1/50 of a housing diameter, said filter screen is multi-layer combined filter screen, and the filtering accuracy of filter screen outer filter material is lower than the filtering accuracy of internal layer filtering material.

Water purifier of the present utility model, owing to have the settling region that certain altitude is arranged, water inlet pipe is again tangentially water to be introduced shell, formation is along garden week flowing water flow, the middle part flow velocity is less, one preliminary sedimentation effect is arranged, and therefore current have improved flow velocity along the disengagement chamber rotational flow in less gap, and make flow velocity greater than filtration velocity, simultaneously screen surface is had cleanup action, the dirt of being removed is stored in the bottom, settling region, opens wash water valve and then dirt can be bled off, simultaneously wash water valve also can in line tap water and take without filtering tap water, adopt multi-layer combined filter screen, to the filteration difference of impurity in the water, thereby can remove multiple harmful substances because each metafiltration material is different, the filtering accuracy of internal layer filtering material is higher than the outer filter material, water is carried out stage treatment, and self cleanup action and the impurity that produce owing to flow velocity is high lodge in each layer of filter screen feasible filtration density loss respectively, reduced concentration polarization, so the filtration efficiency height, flow is big, and quality is good.

Below in conjunction with drawings and Examples water purifier of the present utility model is done detailed explanation.

Fig. 1 is the structural representation of the utility model water purifier;

Fig. 2 is the sectional view of the utility model water purifier along A-A face among Fig. 1.

As Fig. 1 Fig. 2, water purifier has cylinder-like shell 5, be connected in the top cover 11 of shell upper with screw thread or screw, wear ring 12 sealings are arranged between the two, the sidewall that is connected in shell 5 that water inlet pipe 4 is tangential and with shell in be connected, water inlet pipe can be on the bottom or the top of shell 5, rising pipe 14 is connected in the top cover middle part and there is outside screw at two ends, filter cylinder 7 tops with certain intensity have internal thread to link to each other with the outside screw of the inboard of rising pipe 14 and seal mutually with wear ring 13, the other end of rising pipe 14 then can be connected with valve or link to each other with the water inlet pipe of next stage water purifier, the section of filter cylinder 7 can be circular or the folding tubular, porous is arranged to pass through current thereon, on the filter cylinder with stacked and be around in the multi-layer combined filter screen 6 of periphery by several layers of different filtering material, can or tie up and be fixed on the filter cylinder with bonding, fill gac 9 in the filter cylinder 6, the felt material 10 that prevents that gac from overflowing is arranged at gac 9 tops, can certainly not fill gac, water shoot 2 and water discharge valve 1 are arranged on the bottom surface of shell 5, leave enough height between the bottom surface of the bottom surface of shell 5 and filter screen 6 and form settling region 3, this highly is the bigger the better, minimum can not be less than 1/6 of outer cover length, when water quality is bad, the following bottom of the position of water inlet pipe 4 adjacent screen 6 above settling region 3 below the shell 5, when water quality is better, water inlet pipe 4 can be below top cover 11 above the shell 5, it is that 1/10～1/50 of housing diameter makes its gap less that annular space between the outside surface of shell 5 medial surfaces and filter screen 6 should be controlled its diametric gap, form an annular disengagement chamber 8, because the gap is less, so can improve the flow velocity of the water in the disengagement chamber, tangentially flow into along side wall of outer shell from water inlet pipe 4 as the tap water of enough pressure, just formed annularly flow in the enclosure, and flowing up or down along disengagement chamber 8 curls, thereby improved the outer flow velocity of filter screen 6, water from filter screen 6 through and through gac and the rising pipe 14 from the top flows out, in filter screen 6, form filtering velocity, owing to improving, flow velocity make flow velocity greater than filtering velocity, improved filtration efficiency, because the existence and the water inlet pipe of settling region 3 are tangentially intake, in the settling region, reach and separate and cohesion, make impurity obtain precipitation, simultaneously because the flow velocity raising, the filter screen outside surface there is cleaning action, the dirt that cleans also can progressively be deposited in the settling region, can get rid of at any time.When need also can be emitted tap water from valve 1 when not needing filtering water.
