CN2546070Y - Liquid inverse filter - Google Patents

Abstract

The utility model relates to a liquid inverse filter which is filtering device suitable for daily life of people, public place drinking water, sanitary use water or beverage production. The filter is composed of a liquid purifying chamber and a strainer settling chamber. In the process of filtering, the impurities and the feculences blocked by a strainer can automatically deposit on the bottom of the strainer settling chamber, and then the impurities and the feculences are exhausted by a pollution discharge outlet. The utility model solves the problems that the accumulation of the impurities and the feculences on the strainer leads to the blockage of the strainer, unable adoption of high-density strainer and the inexhaustive filtration when the filtration adopts the prior art. Compared with the prior art, much clean water or other clean liquid can be obtained.

Description

The contrary formula filter of liquid

The utility model relates to a kind of device that water or other liquid of impure dirt can be purified.Be specially adapted to people's daily life, the drinking water of public place, the filter that sanitary water or beverage are produced.

At present, known running water filter is to make the water of band impurity dirt flow into filter screen from top to bottom, and the water purification behind strainer filtering is from outflow off the net.Because adopt this structure, the impurity dirt after the filtration accumulates on the filter screen entirely, causes filter screen easily to stop up, and can only adopt the low-density filter screen, it is not thorough to cause the impurity dirt to filter.

Technical problem to be solved in the utility model is, provides a kind of water or other liquid in the process of filtering, and the impurity dirt in the liquid is separated voluntarily with filter screen.Reach and to adopt highdensity filter screen, to obtain filtering the more thorough and nonclogging effect of filter screen than prior art.

In order to realize the above-mentioned technical problem that will solve, the utility model provides a kind of technical scheme unlike the prior art to be: make the water or other liquid that need to filter flow into filter screen from the filter screen below, the clean liquid behind strainer filtering flows out from the top of filter screen.A mud chamber is established in the filter screen below, for being precipitated voluntarily by the impurity dirt under the filter screen arresting.The mud chamber establishes the bottom opening of a band valve, is convenient to discharge at any time the impurity dirt under mud chamber's storage.

In order to obtain better effect, set up magnet circle, magnetized liquid in the above and below of filter screen, the sealing rubber ring that superposes on magnet circle face stops the impurity dirt to enter clean liquid chamber from the limit wall.

The beneficial effects of the utility model are: in the filter process of water or other liquid, the impurity dirt can separate voluntarily with filter screen.Reach and to adopt highdensity filter screen, and filter screen do not produce clogging, to obtain water or other liquid cleaner than prior art.

Below in conjunction with drawings and Examples to real novel the further specifying of this usefulness.

In the accompanying drawing 1, the feed tube front end; 2, feed tube butt joint screw thread; 3, feed tube rear end; 4, imported valve; 5, pressure-reducing cushioning device; 6, buffer fixed cap; 7, mud chamber's butt joint screw thread; 8, sealing ring; 9, magnet circle; 10, filter screen; 11, clean liquid chamber shell; 12, clean liquid outlet; 13, mud chamber's shell; 14, sewage draining valve; 15, sewage draining exit; 16, mud chamber; 17, clean liquid chamber; 18, not filtrate import.Be described in the drawings the structure of the contrary formula filter of the utility model liquid, feed tube front end (1) is connected with feed tube rear end (3) through feed tube butt joint screw thread (2), and imported valve (4) is contained on the feed tube front end (1).Pressure-reducing cushioning device (5) buffer fixed cap is contained in the afterbody of feed tube rear end (3).Clean liquid chamber shell (11) is connected the centre that filter screen (10) is clipped in two magnet circles (9) through mud chamber's butt joint screw thread (7) with mud chamber's shell (13), magnet circle (9) is clipped in the centre of two sealings (8), be close to mutually through screwing of mud chamber's butt joint screw thread (7), and, stop the impurity dirt to enter the bottom that clean liquid chamber (17), sewage draining valve (14) are contained in mud chamber's shell (13) with clean liquid chamber shell (11) inner wall sealing.

In the accompanying drawings, the water of impure dirt or other liquid filtrate import never (18) flow into, flow out through feed tube inlet side (1) imported valve (4) feed tube rear end (3) pressure-reducing cushioning device (5) buffer fixed cap (6), fill mud chamber (16) after magnet circle (9) magnetization, after filter screen (10) filters, fill clean liquid chamber (17) back and flow out from clean liquid outlet (12).In filter process, the impurity dirt by filter screen (10) arresting after, be deposited in mud chamber (16) bottom voluntarily,, discharge when opening through sewage draining valve (14) from sewage draining exit (15).

Claims (2)

1, the contrary formula filter of a kind of liquid.It is characterized in that: clean liquid chamber (17) is on the top of filter screen (10); Feed tube rear end (3) is the upper end of (16) in the mud chamber; Feed tube rear end (3), mud chamber (16) all place the bottom of filter screen (10).

2, the contrary formula filter of a kind of liquid according to claim 1.It is characterized in that: a sewage draining exit (15) is arranged at the bottom of mud chamber (16), and sewage draining exit (15) locates to establish a sewage draining valve (14).
