Technical Field

[0001] The utility model relates to the technical field of filtering, in particular to a filtering component and a filter. Background Art

[0002] The filter is used to remove suspended matter and particulate matter in the water to reduce turbidity and purify water quality, and also reduce the generation of dirt, algae and rust, etc., to ensure the effect of purifying water quality and protect the normal operation of other equipment in the system. The core component of the filter is the filter element. The existing filter element generally has a relatively single filtration accuracy, which makes the filtration incomplete.

[0003] Chinese utility model patent CN219539669U discloses a multi-core integrated filter element for graded filtration, which includes a filter element base, a connecting plate, a plurality of first filter elements and a second filter element. The two ends of the first filter element are respectively connected to the filter element base and the connecting plate, and a plurality of through holes are provided on the connecting plate. One end of the second filter element is connected to the connecting plate. The second filter element is arranged one-to-one with the first filter element. The filtering accuracy of the second filter element is lower than that of the first filter element. The second filter element, the through holes and the first filter element are connected. The multi-core integrated filter element can filter water body step by step, the filter element has good filtering effect, and the integration of multiple filter elements improves the filtering flow rate.

[0004] When filtering, the above-mentioned filter element usually passes through the second filter element first, and then passes through the first filter element for secondary filtration, achieving step-by-step filtration, improving the filtration performance and achieving good filtration effect. At the same time, the integrated structure is adopted, which is more convenient for overall disassembly and assembly, and convenient for filter element replacement.

[0005] However, in the multi-core integrated filter element for graded filtration, the first filter element must be arranged in a one-to-one correspondence with the second filter element. In addition, the filter element can only achieve a two-stage filtration effect.

[0006] How to further optimize the structure and improve the filtering effect is a direction that technical personnel in this field have always needed to improve. Utility Model Content

[0012] Wherein, the end of the first filter element or the second filter element is also connected to a connecting chassis.

[0013] Preferably, a third filter element may be further included, the number of the third filter elements being consistent with the number of through holes, the third filter elements being arranged inside the second filter element and being connected to the corresponding through holes.

[0026] The embodiments of the utility model are further described below in conjunction with the accompanying drawings. Example

[0027] like Figure 1-3 As shown, a filter assembly includes a connecting plate 1, a first filter element 2, a second filter element 3, and a connecting base plate 6.

[0028] The connection disk 1 is formed with 5 through holes 11, which are evenly arranged around the center of the connection disk 1. Of course, the number of through holes 11 is not limited to 5, but can also be 3 or 7. In principle, at least 2 through holes are provided and regularly arranged along the center of the connection disk.

[0029] The number of the first filter cores 2 is consistent with the number of the through holes 11 , and the first filter cores 2 are fixedly mounted at one end of the connecting plate 1 and communicate with the through holes 11 in a one-to-one correspondence.

[0030] Only one second filter core 3 is provided and fixedly mounted on the other end of the connecting plate 1 , and the second filter core 3 can surround all the through holes 11 .

[0031] The connecting chassis 6 is connected to the end of the second filter element 3 away from the connecting disk 1, and an exhaust structure 61 is provided on the connecting chassis 6 to facilitate the exhaust of the filter assembly as a whole. Among them, a handle 62 is provided on the connecting chassis 6 to facilitate the extraction operation of the filter assembly as a whole. Of course, in addition to this, the connecting chassis 6 can also be connected to the end of the first filter element 2 away from the connecting disk 1.

[0032] The first filter element 2 and the second filter element 3 may adopt the same type of filter element structure, or may respectively adopt two different filter element structures, such as one adopting a wound filter element and the other adopting a folded filter element. The filtering accuracy of the first filter element 2 and the second filter element 3 is different.

[0033] Normally, the accuracy of the first filter element 2 is lower than that of the second filter element 3. During filtering, the filter assembly is installed in the filter. First, the fluid medium flows from the outside of the first filter element 2 to the inside of the first filter element 2 to achieve the first stage of filtration. Then, the fluid medium flows through the through hole 11 from the end of the connecting disk 1 close to the first filter element 2 to the end of the connecting disk 1 close to the second filter element 3. Finally, the fluid medium flows from the inside of the second filter element 3 to the outside of the second filter element 3 to achieve the second stage of filtration, thereby ensuring a reliable filtering effect.

[0034] Of course, the precision of the second filter element 3 can also be set to be lower than that of the first filter element 2. When filtering, the filter assembly is installed in the filter. First, the fluid medium flows from the outside of the second filter element 3 to the inside of the second filter element 3 to achieve the first stage of filtration. Then, the fluid medium flows from the end of the connecting plate 1 close to the second filter element 3 to the end of the connecting plate 1 close to the first filter element 2 through the through hole 11. Finally, the fluid medium flows from the inside of the first filter element 2 to the outside of the first filter element 2 to achieve the second stage of filtration. The specific setting can be selected according to the actual situation.

[0035] With the filter assembly of the above structure, only one second filter element is provided and surrounds all through holes, and the second filter element does not need to correspond one-to-one with the first filter element. Example

[0036] like Figure 4 As shown, a filter component, whose structure is compared with that of embodiment 1, and its main difference is: a third filter element 4 is additionally provided, the number of the third filter elements 4 is consistent with the number of through holes 11, and the third filter element 4 is arranged on the inner side of the second filter element 3 and is connected to the through holes 11 accordingly.

[0037] Normally, the accuracy of the first filter element 2 is lower than that of the third filter element 4, and the accuracy of the third filter element 4 is lower than that of the second filter element 3. During filtering, the fluid medium can pass through the first filter element 2, the third filter element 4, and the second filter element 3 in sequence, and three-stage filtration can be achieved, thereby further improving the filtering performance.

[0038] Of course, the accuracy of the second filter element 3 can also be set to be lower than that of the third filter element 4, and the accuracy of the third filter element 4 can be lower than that of the first filter element 2. During filtering, the fluid medium can pass through the second filter element 3, the third filter element 4, and the first filter element 2 in sequence to achieve three-stage filtration. The specific setting can be selected according to actual conditions. Example

[0040] In addition, the connecting chassis 6 may also be connected to an end of the fourth filter element 5 away from the connecting disk 1 .

[0041] Normally, the accuracy of the fourth filter element 5 is lower than that of the first filter element 2, and the accuracy of the first filter element 2 is lower than that of the second filter element 3. During filtering, the fluid medium can pass through the fourth filter element 5, the first filter element 2, and the second filter element 3 in sequence, and three-stage filtration can be achieved, thereby further improving the filtering performance.

[0042] Of course, the accuracy of the second filter element 3 can also be set to be lower than that of the first filter element 2, and the accuracy of the first filter element 2 can be lower than that of the fourth filter element 5.

[0045] Only one fourth filter element 5 is provided, and the fourth filter element 5 is fixedly mounted on an end of the connecting plate 1 away from the second filter element 3 , and the fourth filter element 5 surrounds all the first filter elements 2 .

[0046] In addition, the connecting chassis 6 may also be connected to an end of the fourth filter element 5 away from the connecting disk 1 .
