Embodiment approach

[0028] Wherein, as an embodiment of the connection structure, the first retaining ring 113 is provided with through holes spaced along the circumferential direction of the first retaining ring, and the second retaining ring 123 is provided with The through holes are one-to-one corresponding to the threaded holes; then the connecting structure includes screws respectively passing through the through holes from the outside of the first retaining ring to fit and connect with the corresponding threaded holes. In addition, as an embodiment of the contact sealing structure, the contact sealing structure includes a sealing ring 124 disposed on the end surface of the second retaining ring 123 .

[0029] Since the first retaining ring 113 and the second retaining ring 123 are provided, when the second retaining ring 123 is in contact with the first retaining ring 6113 when the second filter element 120 is pulled out from the first filter element 110, the second filter element 120 will ...

Abstract

The invention discloses a filter element which solves the technical problems that the filter area of the filter element is increased and the mutual contradiction between packaging cost of the filter element and the transportation cost of the filter element is reduced in the prior art. The filter element comprises a first filter element and a second filter element, wherein the second filter element is selectively in one of the two states that the second filter element is arranged in the first filter element and the second filter element is pulled out from the first filter element; during working, the second filter element is in the state of being pulled out from the first filter element and is connected with the first filter element to form a whole body. In the packaging and transportation process of transferring the filter element to a filter element using place from a filter element manufacturing place, the second filter element is arranged in the first filter element, so that the packaging cost is reduced, the transportation space for occupying a single filter element is also reduced, and the transportation cost is reduced; when the filter element works, the second filter element is pulled out from the first filter element and is connected with the first filter element to form the whole body, so that the filter area of the whole filter element is equal to the sum of the area of the first filter element and the area of the second filter element, and the total filter area of the filter element is increased.

Description

technical field [0001] The invention relates to the technical field of filtration, in particular to a filter element. Background technique [0002] The filtration area is an important index to evaluate the performance of the filter element. The larger the filtration area, the more the filter element can handle in a unit time. Without changing the structure of the filter element, in order to increase the filtering area of ​​the filter element, the size of the filter element can only be increased. For example, the applicant of the present invention has developed a tubular filter element with a longer length than the existing tubular filter element in order to increase the filtering area of ​​the tubular filter element in actual production and operation activities. Under the condition of the same diameter, due to the increased length, the tubular filter element developed by the applicant of the present invention has a larger filtering area than the existing tubular filter ele...
