Problems solved by technology

But in reality, the filter element is only polluted and clogged on the surface, and its interior has not been polluted or clogged, that is, the interior has not completely lost its filtering performance.
Therefore, the existing water filter element has the problems that the filtration performance cannot be used up, the service life is short, and the material waste is serious.

Embodiment 1

[0017] Such as figure 1 As shown, the water filter element of this embodiment includes a support frame 100 and a filter material 200 wound on the support frame 100 , and end caps 300 for fixing the filter material 200 are connected to both ends of the support frame 100 .

[0018] The filter material 200 is a microfiltration membrane or an ultrafiltration membrane, such as a non-woven fabric filter material, an air filter fiber material, a 1 micron filter membrane, and the like.

[0019] In this embodiment, the filter material 200 is composed of continuous sheet-shaped filter material units 201, and the adjacent sheet-shaped filter material units 201 are completely separated, but the head of the lower layer sheet-shaped filter material unit is pressed against the upper layer. The way on the tail of the sheet filter material unit is connected. Wherein the width of the pressure is 15-30mm. In this way, the invention of the overlapping width makes the winding quality better, and...

Embodiment 2

[0021] Such as figure 2 As shown, the difference between the present embodiment and the second embodiment is that the sheet filter material units 201 are connected, but there are tear lines 202 or imaginary knife lines at the connection positions. Such a connection structure is also very beneficial to the separation of the sheet filter material units.

[0022] The above are the two structural forms of the water filter element of the present invention. After it has been used for a period of time, when the filter material of the outer layer is polluted and blocked, this part of the sheet filter material unit can be removed, and the filter material inside can be continued. It is not necessary to replace the entire filter element to maximize the filtering performance, which improves the service life of the filter element and saves the cost of filter materials.

[0023] Therefore, the water filter element of the present invention has the advantages of reducing the material waste ...

Abstract

The invention discloses a water filtration filter element comprising a support skeleton and a filter material wound on the support skeleton, wherein the filter material is composed of continuous sheet filter material units, and a connection structure capable of being separated conveniently is arranged between the adjacent sheet filter material units. The water filtration filter element provided by the invention has the advantages that the waste caused by the filter element is reduced and the service life of the filter element is prolonged by multiple times.

Description

technical field [0001] The invention belongs to the technical field of household water treatment and relates to a water filter element. Background technique [0002] The existing ultrafiltration membrane filter elements and microfiltration membrane filter elements are basically coated with filter materials on the support frame. After the filter element is used for a period of time, its outer surface will be blocked by pollution, which will affect the filtering effect. At present, when such a situation occurs in the filter element, the filter element is usually discarded and replaced with a new filter element. But in reality, the filter element is only polluted and clogged on the surface, and its interior is not polluted or clogged, that is, the interior has not completely lost its filtering performance. Therefore, the existing water filter element has the problems of incomplete filtration performance, short service life and serious material waste. Contents of the inventi...
