[0038] See also Figure 1-3 As shown, this embodiment provides a filtering tube sheet flange, including: a first flange 100, which is provided with a plurality of first through holes 101 along the circumferential direction, and the axis of the first through hole 101 is arranged parallel to the axis of the first flange 100; a second flange 110, which is provided with a plurality of second through holes 111 along the circumferential direction, and the axis of the second through hole 111 is arranged parallel to the axis of the second flange 110; wherein the first through hole 101 and the second through hole 111 are fixedly connected by bolts; and a filter assembly 130, which is arranged between the first flange 100 and the second flange 110.

[0039] It can be seen that the first flange 100 and the second flange 110 can be connected by bolts to form a closed pipeline system; the filter assembly 130 is arranged between the first flange 100 and the second flange 110, and can filter the fluid flowing through the pipeline system to remove impurities and particulate matter therein, thereby ensuring the purity and quality of the fluid.

[0040] It can be understood that the filter tube sheet flange provided in this embodiment has the advantages of simple structure, easy installation, good filtering effect, uniform and stable fluid flow, and replaceable and adjustable filter assembly 130, and is suitable for the filtering needs of various fluid pipeline systems.

[0041] Specifically, the filtering tube sheet flange also includes: a first groove, which is opened at one end of the first flange 100; a second groove, which is opened at one end of the second flange 110; wherein the cross-sectional area of ​​the first groove is equal to the cross-sectional area of ​​the second groove, the first groove and the second groove constitute a groove 140, and the inner surface of the groove 140 is provided with a thread.

[0042] It can be seen that the first groove and the second groove can not only make the connection of the filter tube sheet flange tighter, but also facilitate the installation of the filter assembly 130; since the cross-sectional areas of the first groove and the second groove are equal, when the first flange 100 and the second flange 110 are fixedly connected by bolts, the space inside the groove 140 forms a complete flow channel, and the fluid can flow from the first flange 100 to the second flange 110 through this flow channel, and at the same time be filtered by the filter assembly 130 arranged between the two.

[0043] It can be understood that the inner surface of the groove 140 is provided with a thread, which can very conveniently install the filter component 130 in the groove 140; one end of the filter component 130 can be provided with a thread structure matching the thread, and the filter component 130 can be fixed in the groove 140 by rotating it, thereby realizing the replacement and adjustment of the filter component 130.

[0052] Specifically, the second filter layer 132 is an activated carbon adsorption layer.

[0053] Specifically, the third filter layer 133 is a ceramic filter material layer.

[0054] It can be seen that the combination of stainless steel mesh layer, activated carbon adsorption layer and ceramic filter material layer can achieve multi-stage filtration of the fluid, effectively remove impurities and particulate matter in the fluid, and improve the purity and quality of the fluid; the stainless steel mesh layer can preliminarily intercept large particles of impurities, the activated carbon adsorption layer can adsorb organic matter and odor in the fluid, and the ceramic filter material layer can further filter fine particles to ensure the cleanliness of the fluid.
