Description

Technical Field

[0001] The utility model relates to the technical field of filtration, and in particular to an integrated filtration component for multi-stage filtration 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

[0025] The embodiments of the utility model are further described below in conjunction with the accompanying drawings. Example

[0026] like Figure 3-4 As shown, an integrated filter assembly for multi-stage filtration includes a first filter element 1, a second filter element 2, a third filter element 3, a first connecting plate 5, a second connecting plate 6, and a third connecting plate 7.

[0027] The first connecting plate 5 is formed with three first through holes 51, which are evenly arranged around the center of the first connecting plate 5. Of course, the number of the first through holes 51 is not limited to 5, but may be 5 or 7. In principle, at least one first through hole is provided.

[0028] Five second through holes 61 are formed on the second connecting plate 6, and the five second through holes 61 are evenly arranged in the circumferential direction with the center of the second connecting plate 6 as the center. Of course, the number of the second through holes 61 is not limited to 5, and can also be 3 or 7. In principle, at least one second through hole is provided. The number of the second through holes 61 can be the same as or different from the number of the first through holes 51, and the projections of the second through holes 61 and the first through holes 51 in the axial direction are staggered and do not overlap each other.

[0029] One end of the first filter element 1 is connected to the first connecting plate 5, and the first filter element 1 can surround all the first through holes 51. The number of the first filter elements 1 is the same as the number of the first through holes 51, and a total of three first filter elements 1 are provided, and each first filter element 1 is provided in a one-to-one correspondence with each first through hole 51, thereby forming an enclosure for all the first through holes 51. Of course, only one first filter element can also be provided, and all the first through holes are all located on the inner side of the first filter element, thereby achieving the purpose of the first filter element surrounding all the first through holes.

[0030] The second filter element 2 is arranged between the first connecting plate 5 and the second connecting plate 6, and its two ends are fixedly connected to the first connecting plate 5 and the second connecting plate 6 respectively, and the second filter element 2 can surround all the second through holes 61 and stagger with the first through holes 51. Similarly, the number of second filter elements 2 is the same as the number of second through holes 61, and a total of 5 are arranged, and each first filter element 2 is arranged in a one-to-one correspondence with each first through hole 51, thereby forming an enclosure for all the first through holes 51. Of course, only one second filter element can also be arranged, and all the second through holes are all located on the inner side of the second filter element, and all the first through holes are all located on the outer side of the second filter element, so as to achieve the purpose of the second filter element surrounding all the second through holes and staggering with the first through holes.

[0031] The third filter element 3 is arranged at one end of the second connecting plate 6 away from the second filter element 2, and the third filter element 3 can surround all the second through holes 61. Similarly, the number of the third filter elements 3 is the same as the number of the second through holes 61, and a total of 5 third filter elements 3 are arranged, and each third filter element 3 is arranged in a one-to-one correspondence with each second through hole 61, thereby forming a surround for all the second through holes 61. Of course, only one third filter element can also be arranged, and all the second through holes are all located on the inner side of the third filter element, and all the first through holes are surrounded by one third filter element at the same time.

[0032] The third connecting plate 7 is connected to the end of the third filter element 3, and a handle 71 is provided on the third connecting plate 7. The third connecting plate 7 makes it easier to seal with the filter. The handle structure is provided to facilitate the extraction operation of the entire filter assembly, which is beneficial to the disassembly, assembly and replacement of the filter assembly in the filter.

[0033] Generally, the first filter element 1, the second filter element 2, and the third filter element 3 have different filtering accuracies. According to the relative positions of the filter elements, their filtering accuracies are successively improved along the medium flow direction. Of course, the filter elements at adjacent positions may have the same accuracies. In addition, the first filter element 1, the second filter element 2, and the third filter element 3 may adopt the same type of filter element structure, or may adopt a variety of different filter element structures, such as some using winding filter elements, others using folded filters, or stacked filter membrane stacks, or even ordinary filter nets.

[0034] like Figure 4 As shown, during filtering, the fluid medium first flows from the outside of the first filter element 1 to the inside of the first filter element 1 to achieve the first stage of filtration, and then the fluid medium passes through the first through hole 51 to the other side of the first connecting plate 5 and the outside of the second filter element 2, and flows from the outside of the second filter element 2 to the inside of the second filter element 2 to achieve the second stage of filtration, and then the fluid medium passes through the second through hole 61 to the other side of the second connecting plate 6 and the inside of the third filter element 3, and flows out from the inside of the third filter element 3 to the outside of the third filter element 3 to achieve the third stage of filtration, thereby ensuring a reliable filtering effect.

[0035] Of course, it can also be set in the opposite direction, that is, the third connecting plate can also be connected to the end of the first filter element. During filtering, the fluid medium first flows from the outside of the third filter element 3 to the inside of the third filter element 3 to achieve the first stage of filtration, and then the medium passes through the second through hole 61 to the inside of the second filter element 2, and flows out from the inside of the second filter element 2 to the outside of the second filter element 2, and then the fluid medium passes through the first through hole 51 to the inside of the first filter element 1, and flows out from the inside of the first filter element 1 to the outside of the first filter element 1, to achieve the third stage of filtration, thereby ensuring a reliable filtering effect.

[0036] By adopting the above scheme, the first filter element is arranged corresponding to the first through hole on the first connecting plate, and the second filter element is arranged offset from the first through hole on the first connecting plate, so that the number, position and layout of the first filter element and the second filter element do not affect each other, and there is no need to arrange them one by one; in addition, by arranging the first filter element, the second filter element and the third filter element in sequence, three-stage filtration can be achieved, further improving the filtration effect. Example

[0037] like Figure 5 As shown, an integrated filter assembly for multi-stage filtration includes a first filter element 1, a second filter element 2, a third filter element 3, a fourth filter element 4, a first connecting plate 5, a second connecting plate 6, a third connecting plate 7 and a fourth connecting plate 8.

[0038] Compared with the first embodiment, a fourth filter element 4 and a fourth connecting plate 8 are mainly added. The fourth connecting plate 8 is formed with at least one fourth through hole. One end of the fourth connecting plate is connected to the first filter element, and the first filter element and the fourth through hole are staggered.

[0039] It also includes at least one fourth filter element, which is installed at one end of the fourth connecting plate away from the first filter element, and the fourth filter element can surround all the fourth through holes.

[0040] Compared with the first embodiment, the second embodiment further adds one level of filtration, that is, four-level filtration is achieved, and the filtration effect is further improved.

[0041] In addition, we can also use the same method to further stack and achieve 5, 6 or even more levels of filtering. Of course, usually, 2-4 levels of filtering are more in line with actual needs. Example

[0042] like Figure 1-4 As shown, a filter includes a cylinder 9, a cover plate 11 and an integrated filter assembly 10 for multi-stage filtration as described in the first embodiment.

[0043] The cylinder 9 is formed with a filter cavity with an opening at the upper end, a feed inlet 91 is provided at the bottom of the cylinder 9, and a discharge outlet 92 is provided on the side wall of the cylinder 9 close to the upper end.

[0044] The integrated filter assembly 10 of the multi-stage filtration is installed in the filter chamber of the cylinder 9, and the first connecting plate 5, the second connecting plate 6, and the third connecting plate 7 are all sealed with the inner wall of the filter chamber, so that the filter chamber is divided into the first chamber 93, the second chamber 94, and the third chamber 95 from bottom to top, and the feed port 91 is connected to the first chamber 93, and the discharge port 92 is connected to the third chamber 95. Among them, a multi-layer support card is also provided on the inner side wall of the filter chamber, which is used for positioning and supporting the first connecting plate 5, the second connecting plate 6, and the third connecting plate 7, respectively, which is more conducive to the positioning and installation of the filter assembly in the cylinder. Of course, although it is not clearly shown in the figure, in fact, the diameters of the first connecting plate 5, the second connecting plate 6, and the third connecting plate 7 are actually increased in sequence, and the cylinder and each supporting card have a certain reduction in diameter from top to bottom. When installing the integrated filter assembly of the multi-stage filtration, it can be directly inserted into the filter chamber of the cylinder from the upper end opening of the cylinder 9, and it is very convenient to disassemble.

[0045] In addition, the cover plate 11 is detachably mounted on the upper end of the cylinder 9, and fixes and compresses the integrated filter assembly 10 of the multi-stage filtration, so that the filter assembly can be stably and reliably installed in the filter cavity of the cylinder 9. The cover plate 11 is formed with an opening groove corresponding to the handle, and the handle can extend out of the cover plate 11 through the opening groove, which makes it more convenient to grab and move the filter as a whole.

[0046] During filtering, the above-mentioned filter is connected to the pipeline of the filtering system, and the material can enter the filtering chamber from the feed port 91. After multiple filtrations, the material is discharged from the discharge port 92. The integrated filtering component with multi-stage filtration in the filter is not only simple and compact in structure and easy to disassemble and assemble, but also can realize multi-stage filtration to ensure reliable filtering effect.
