Abstract

The utility model relates to a multi-stage filter which is convenient to wash, and the multi-stage filter can be used time and again. The utility model is formed by that a multi-stage filtering core which is formed by that circular-tube-shaped multi-stage filtering tubes are connected in series is arranged in a cylindrical casing; each stage of filtering tube is sheathed with a water stopping ring; an inlet hole and a filtering screen are arranged on a pipe wall at one side of the water stopping ring; an outlet hole is arranged on the pipe wall at the other side; each stage of filtering screen is orderly connected along the entire filtering core; after entering into the filter, water flows by the filtering screens, inlet holes and outlet holes on each stage of filtering tube, and finally the water flows out of an outlet pipe. Impurities on each stage of filtering net can be conveniently and thoroughly brushed by that the filtering core is taken out, and the utility model can be used that the filtering core is installed again.

Description

Tubular multistage filter

The utility model relates to a kind of filter, filters and remove the solid impurity in the water on the especially suitable domestic running water pipe.

Present common filter, mostly adopt one from outside to inside, concentric multistage filtering core from coarse to fine is as the core component of filter, this multistage filtering core forms an interlayer between every two-stage filter screen, blocked by impurity such as silts easily, and the impurity in the interlayer cleans inconvenience, not thorough, and the people of use is fewer and feweri.

The purpose of this utility model provides a kind of filter, and it not only can realize multiple filtration, and can remove the impurity on the filter screen easily and thoroughly, uses repeatedly, can also add and change materials such as charcoal in screen pipe, and water is gone the sterilization of distinguishing the flavor of.Can also several this cast multistage filter series combination, make the filter of various different sizes according to different requirements in addition.

The purpose of this utility model is achieved in that in the cylindrical jacket of an even thickness, the tubular of packing into, separate and each section pipe outside, spare the multistage filtering core that the multistage filtering pipe that is with a water blocking ring is connected in series in the pipe.The space all and between the filter overcoat is left in the whole filter core outside of crossing except water blocking ring.Even on the tube wall around each grade screen pipe water blocking ring one side have screen pack outside inlet opening and the hole, and have apopore on water blocking ring opposite side tube wall.Each grade screen pack all connects in turn along the whole filter core of crossing like this, the whole pipe closedtop mouth of crossing filter core.During work, after water enters filter from water inlet pipe, enter filter screen and inlet opening on each grade screen pipe successively, flow out apopore again, the outlet pipe from filter overcoat one side flows out at last.Reach the purpose of multistage filtering.During cleaning,, the impurity on every grade of filter screen is cleaned with water, can be reinstalled use as long as take out the multistage filtering core.

Because, adopted above scheme, can be when water be carried out multistage filtering, in screen pipe, add thing piece such as charcoal to the water sterilization of going to distinguish the flavor of; Take out filter core, after the impurity on each grade filter screen is thoroughly cleaned with water, can reinstall use.

Below in conjunction with accompanying drawing to this practical further specifying.

Fig. 1 is an outside drawing of the present utility model.

Fig. 2 is an assembly structure figure of the present utility model.

Fig. 3 is a vertical section of the present utility model structural map.

Among the figure: 1. 10. 3 grades of filter screens of water inlet pipe 2. filter overcoats, 3. outlet pipe 4. sealing rings, 5. filter core bonnet 6. one-level filter screens, 7. inlet opening 8. water blocking ring, 9. secondary filter screens, 11. filter courses, 12. apopores, 13. pipe internal partitions 14. are crossed filter core 15. and are crossed filter core base 16. charcoals 17. bonnet draw-in grooves.

In Fig. 1, water inlet pipe (1) is connected with filter overcoat (2) one ends, and outlet pipe (3) is connected on the other end tube wall of filter overcoat (2), crosses filter core (5) and is connected with filter overcoat (2) by screw thread, in order to prevent the interface water outlet, at a junction cover sealing ring (4).

In Fig. 2, cross filter core (14) and be connected in series by the overanxious pipe of level Four.Wherein the final stage screen pipe is connected with the whole filter core of crossing by screw thread, is convenient to open interior charcoal and other germicide pieces of replace tubes of chimney filter.All be stamped one deck filter screen outside each grade screen pipe inlet opening (7), filter screen is preferably selected not stainless steel filtering net, and copper mesh also can.Wherein one-level filter screen (6) suggestion is about 250 orders, and secondary filter screen (9) advises that about 350 orders, three grades of filter screens (10) are advised about 450 orders.The overanxious layer of final stage (11) is advised with foamed plastic or other superfine fibre layers.The aperture of final stage apopore (12) suggestion diameter 3 millimeter is to prevent that managing interior germicide piece flows out.Whole cross filter core (14) and pack in the filter overcoat (2) after, the inwall of water blocking ring (8) and filter overcoat (2) closely offsets, when rotation tightened filter bonnet (5), whole filter core (14) should be along with rotation excessively.Water blocking ring (8) and sealing ring (4) should adopt rubber ring.

In Fig. 3, cross between the inwall of filter core (14) and filter overcoat (2) and leave the space, in the final stage screen pipe of crossing filter core (14), charcoal and germicide piece (16) are housed, cross filter core base (15) cover and be embedded in the bonnet draw-in groove (17) of filtration core bonnet (5).When filter is worked, after water enters filter from water inlet (1), under the stopping of every grade of water blocking ring (8), can only enter each grade filter screen and inlet opening successively, outflow water outlet sky, enter the final stage screen pipe at last, go to distinguish the flavor of after the sterilization, flow out final stage apopore and delivery port (3) by charcoal lump (16).

Claims

1. filter, in a columniform overcoat, the multistage filtering core that the multistage filtering pipe of packing into is connected in series, each grade screen pipe all is with a water blocking ring outward, on the water blocking ring one side pipe wall filter screen and inlet opening are arranged, on the opposite side tube wall apopore is arranged, it is characterized in that: each grade filter screen (with filter course) all is connected in turn along crossing filter core.

2. filter according to claim 1 is characterized in that: screen pack is all arranged on the inlet opening of each grade screen pipe.
