Abstract

The invention relates to a multilayer filter, which comprise: an upper base, a water inlet, a water outlet, and the first filter screen connected to the folded end cover, wherein the end cover is fixed to one end of folded core; the wall of folded core has holes; the folded core contains skeleton that contains fluorate; the skeleton has water inlet; one end of transition connector is fixed with the folded core, while another end via the second screen network is connected to the inner cylinder; the inner cylinder has filter material; one end of skeleton is through to the filter material; the upper cover of inner cylinder via the third filter screen is connected to the end of inner cylinder; the end cover of inner cylinder via the first sealing ring is connected to the upper cover; the open end of frame is fixed on the end cover of cylinder; there is space between the inner cylinder and the frame through to the water inlet; the inner cylinder contains water outlet tube whose wall has several holes; one end of water outlet tube is through to the water outlet, while another end is sealed. The invention has better filter effect and low cost.

Description

Multilayer filter

Technical field

The present invention relates to a kind of filter.

Background technology

In order to improve the quality of living, general Drinking Water all need filter, and at present general water filter filter effect is also bad, and the cost of good filtration effect is higher again, is difficult for being accepted by the public.

Summary of the invention

In order to overcome above-mentioned defective, the invention provides a kind of multilayer filter, this filtration device structure is reasonable, the lower and good filter effect of tool of cost.

The present invention for the technical scheme that solves its technical problem and adopt is: a kind of multilayer filter, comprise the seat of honour, water inlet on the seat of honour, delivery port, the seat of honour is fixed on the inner barrel end cap by second and third sealing ring, is provided with the first secondary filter net, folding end cap, folded core, transit joint, the second secondary filter net, inner barrel, the 3rd secondary filter net, inner barrel loam cake, first sealing ring, inner barrel end cap in the filter cylinder shell successively; The first secondary filter net is right after folding end cap, folding end cap is fixed on folded core one end, establish the hole of supplying water and flowing on the folded core wall, be provided with skeleton in the folded core, be provided with hydrochlorate in the fluorine in the skeleton, skeleton is provided with several inlet openings, transit joint one end is fixed on folded core, the other end is connected by the second secondary filter net and inner barrel, be provided with filter material in the inner barrel, filter material in skeleton one end and the inner barrel communicates, the inner barrel loam cake is fixed on the inner barrel termination by the 3rd secondary filter net, and the inner barrel end cap is fixed on the inner barrel loam cake by first sealing ring; The filter cylinder shell aperture end margin fixed cylinder end cap that extends internally, leave certain gap between inner barrel and filter cylinder shell for water inlet, the gap communicates with water inlet on the seat of honour, be provided with outlet pipe in the inner barrel, the water outlet tube wall is provided with several holes of supplying water and flowing into, outlet pipe one end communicates with delivery port on the seat of honour, and the outlet pipe other end is sealing, in order to prevent not flow directly in the outlet pipe through the water of filter material.

The invention has the beneficial effects as follows: owing to be provided with multi-level filtration, so filter effect is better, and this topology layout is reasonable, and whole cost is lower.

The specific embodiment

Embodiment: referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, a kind of multilayer filter, comprise the seat of honour 14, water inlet on the seat of honour 14, delivery port, the seat of honour 14 is fixed on the inner barrel end cap 11 by second and third sealing ring, be provided with in the water after water that second and third sealing ring can prevent water inlet end is sneaked into filtration, be provided with the first secondary filter net 1, folding end cap 2, folded core 3, transit joint 5, the second secondary filter net 6, inner barrel 7, the 3rd secondary filter net 8, inner barrel loam cake 9, first sealing ring 10, inner barrel end cap 11 in the filter cylinder shell 15 successively; The first secondary filter net 1 is right after folding end cap 2, folding end cap 2 is fixed on folded core 3 one ends, establish the hole of supplying water and flowing on folded core 3 walls, be provided with skeleton 4 in the folded core 3, be provided with hydrochlorate 16 in the fluorine in the skeleton 4, skeleton 4 is provided with several inlet openings, transit joint 5 one ends are fixed on folded core 3, the other end is connected by the second secondary filter net and inner barrel 7, be provided with filter material 21 in the inner barrel 7, filter material in skeleton 4 one ends and the inner barrel 7 communicates, inner barrel loam cake 9 is fixed on inner barrel 7 terminations by the 3rd secondary filter net 8, and inner barrel end cap 11 is fixed on inner barrel loam cake 9 by first sealing ring 10; The filter cylinder shell 15 open end edge fixedly inner barrel end cap 11 that extends internally, 15 on inner barrel 7 and filter cylinder shell leave certain gap 18 for water inlet, and the gap communicates with water inlet 17 on the seat of honour; Be provided with outlet pipe 19 in the inner barrel, outlet pipe 19 walls are provided with several holes that supply water to flow into, and outlet pipe one end communicates with delivery port 20 on the seat of honour, and the outlet pipe other end is closed, in order to prevent not flow directly in the outlet pipe through the water of filter material.

Filter material 21 can be grain active carbon in this example, and grain active carbon can be used other filter material according to demand instead certainly.

The course of work of the present invention is: running water enters from water inlet, flow in the gap 18 of inner barrel 7 and filter cylinder shell 15, flow into and flow to folded core 3, because the existence of hydraulic pressure, hydrochlorate in folded core flows into fluorine advance the skeleton 4 (by the inlet opening on the skeleton 4) again, water again in fluorine hydrochlorate flow to the filter material of inner barrel 7 by the second secondary filter net 6, water flow in the outlet pipe 19 by the hole on the outlet pipe tube wall from filter material again, last water flows to the delivery port 20 at the seat of honour from outlet pipe, flows to the user and uses.

In this example, the water inlet 17 on the seat of honour, delivery port 20 are prior art, and this example no longer describes its structure in detail.
