Further, a first slot 250 is formed between the second support bar 240 and the third support ring 220 to match with the first flange 122; the second support bar 240 and the fourth support ring 230 form a second slot 260 therebetween for engaging the second flange 132. The first flange 122 and the first slot 250 are added between the first barrel 100 and the second barrel 200, or the second flange 132 and the second slot 260 are used as a connecting and matching structure, so that the connecting firmness between the first barrel 100 and the second barrel 200 can be further improved.

In this embodiment, first barrel spare 100 and second barrel spare 200 all adopt plastics to make, this one side makes first barrel spare 100 and second barrel spare 200 have certain intensity, can play the support cartridge filter, prevents that the cartridge filter from being collapsed the effect of deformation, and on the other hand can produce the deformation of certain degree again, and each protruding card of being convenient for is gone into corresponding recess, and each flange card of also being convenient for goes into respective slot. Of course, in other embodiments, first cartridge 100 and second cartridge 200 may be made of metal, composite, or other materials.

Specifically, the outer diameter of the first cartridge 100 is the same as the outer diameter of the second cartridge 200. Alternatively, the outer diameter of the first cartridge 100 is larger than the outer diameter of the second cartridge 200. Alternatively, the outer diameter of the first cartridge 100 is smaller than the outer diameter of the second cartridge 200. This arrangement allows only a new mold for manufacturing the first or second

cylindrical member

100 or 200 to be used when manufacturing a new filter element center tube 10 having a new outer diameter, which greatly reduces the manufacturing cost of the filter element center tube 10. Specific examples are as follows;

in one embodiment, as shown in fig. 1-4, a 30mm outer diameter cartridge center tube 10 is spliced using a first 30mm outer diameter cartridge 100 and a second 30mm outer diameter cartridge 200. Because the filter cartridge supported by the filter cartridge central tube 10 is sleeved outside the filter cartridge central tube 10, and the interior of the filter cartridge central tube 10 is a channel for fluid to flow, as long as the outer diameter of at least one part of the tube members forming the filter cartridge central tube 10 is 35mm, even if the outer diameter of the other part of the tube members forming the filter cartridge central tube 10 is less than 35mm, the filter cartridge central tube 10 can also play a role in supporting the filter cartridge and enabling fluid to pass through. Therefore, in another embodiment, as shown in fig. 5 to 7, when a filter element center tube 10 with an outer diameter of 35mm is required, a first tube 100 with an outer diameter of 35mm and a second tube 200 with an outer diameter of 30mm can be used, or the first tube 100 with an outer diameter of 30mm and the first tube 100 with an outer diameter of 35mm can be spliced, that is, only a mold for manufacturing the first tube 100 or the second tube 200 with an outer diameter of 35mm is needed. At this time, the inner diameter of the first cartridge 100 in fig. 7 is equal to the inner diameter of the first cartridge 100 in fig. 3, so that the second cartridge 200 having an outer diameter of 30mm is caught. Furthermore, if the filter element center tube 10 with the outer diameter of 30mm is not needed to be used temporarily, the filter element center tube 10 with the outer diameter of 30mm can be disassembled, and the first cylinder 100 or the second cylinder 200 with the outer diameter of 30mm is used for splicing the new filter element center tube 10 with the outer diameter of 35mm, so that the use of manufacturing materials is saved, and the manufacturing cost of the filter element center tube 10 is further reduced. In other embodiments, the sizes of the first cylinder 100 and the second cylinder 200 can be adjusted according to actual needs.

The cartridge central tube 10 described above has at least the following advantages:

the filter element center tube 10 and the filter element assembly include a first cylinder 100 and a second cylinder 200, and the first cylinder 100 and the second cylinder 200 can be engaged with a third engaging portion or a fourth engaging portion via a first engaging portion, so as to form a structure in which at least one first cylinder 100 and at least one second cylinder 200 are alternately arranged along an axial direction. With the filter element center tube 10 having such a structure, the filter element center tube 10 with a proper size can be spliced for use only by selecting the first cylinder 100 and the second cylinder 200 with proper outer diameters and numbers according to actual needs (such as the length of a pipeline and the size of a filter cartridge). Thus, only one first cartridge 100 and one second cartridge 200 are required to mold the cartridge center tube 10 to different lengths, and the used cartridge center tube 10 can be disassembled into at least one first cartridge 100 and at least one second cartridge 200 and then reassembled into a new cartridge center tube 10 as needed. Therefore, the filter element center tube 10 can save the material and the casting mold for manufacturing the filter element center tube 10, and the manufacturing cost of the filter element center tube 10 is greatly reduced.

Example 2

An embodiment of the present invention further provides a filter element center tube assembly group, comprising at least a first cartridge, a second cartridge and a third cartridge (not shown in the drawings). The first barrel 100 has a first fitting portion and a second fitting portion at its opposite ends. The two ends of the second cylinder 200 are respectively provided with a third matching part and a fourth matching part. And a fifth matching part and a sixth matching part are respectively arranged at two ends of the third cylinder. Wherein the third mating portion is mateable with the first mating portion and the fourth mating portion is mateable with the second mating portion; the third matching portion can be matched with the fifth matching portion, and the fourth matching portion can be matched with the sixth matching portion. Wherein, the outer diameter of the first cylinder 100 is larger than or equal to the outer diameter of the second cylinder 200, and the outer diameter of the third cylinder is larger than or equal to the outer diameter of the second cylinder 200; the outer diameter of the first cartridge 100 is not equal to the outer diameter of the third cartridge.

In this embodiment, the axial length of the second cylinder 200 is less than or equal to 10 mm. The smaller axial length of the second cartridge 200 prevents the collapse of the filter cartridge due to the longer length of the second cartridge 200, which has a relatively smaller outer diameter, from being unsupported by the filter cartridge center tube 10. Of course, in other embodiments, the axial length of the second barrel 200 can be adjusted according to actual needs.

Specifically, the first mating portion and the second mating portion have the same shape, the third mating portion and the fourth mating portion have the same shape, and the fifth mating portion and the sixth mating portion have the same shape. This setting makes things convenient for the both ends of first section of thick bamboo piece 100 and the both ends free combined connection of second section of thick bamboo piece 200 to and the both ends of third section of thick bamboo piece and the both ends free combined connection of second section of thick bamboo piece 200 need not to distinguish different ends, has increased the application scope and the installation convenience of second section of thick bamboo piece 200 and first section of thick bamboo piece 100, second section of thick bamboo piece 200 and third section of thick bamboo piece.

In this embodiment, other structural features and connection relationships of the first barrel 100, the second barrel 200 and the third barrel are as in embodiment 1, and are not described herein again.

The filter element central tube component group at least has the following advantages:

in this filter core center tube assembly group, the first and

second cartridges
