Embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts. Furthermore, although terms used in the present invention are selected from publicly known and commonly used terms, some terms mentioned in the present specification may be selected by the applicant at his or her discretion, the detailed meanings of which are described in relevant parts of the description herein. Furthermore, it is required that the present invention is understood, not simply by the actual terms used but by the meaning of each term lying within.
Referring to fig. 1 to 3, the present invention proposes a core-grade seal oil filter core, which includes a filter core outer frame 10 and a base 20, wherein the filter core outer frame 10 has a mounting end 110, and the filter core outer frame 10 is provided with at least one first connecting member 120 at the mounting end 110; at least one second connecting piece 210 is arranged on the base 20, and the filter element outer framework 10 is connected with the base 20 in advance through clamping between the first connecting piece 120 and the second connecting piece 210.
The conventional filter element outer frame 10 and the base 20 are generally connected only by welding or bonding, and in this connection mode, the periphery of the bottom shell of the filter element outer frame 10 is easily broken by compression due to the increase of flow or the increase of viscosity of the filter medium, so that the leakage of the pipeline and the disassembly of the filter element are caused, and impurities cannot be effectively filtered.
Therefore, this application sets up at least one first connecting piece 120 at the installation end 110 of filter core exoskeleton 10, then set up on base 20 with first connecting piece 120 looks adaptation joint's second connecting piece 210, through the joint cooperation of first connecting piece 120 and second connecting piece 210, improve the joint strength between filter core exoskeleton 10 and the base 20, further combine the joint mode such as bonding or welding to improve the structural strength of nuclear seal oil filter core by a wide margin again.
In one embodiment, the first connector 120 is a plurality of snap teeth extending inwardly around the outer perimeter boundary of the mounting end 110. Correspondingly, the second connecting piece 210 is a clamping groove matched with the clamping tooth.
It should be noted that, when the working flow rate of the filter element increases or the viscosity of the filter medium increases, the outer edge of the bottom end of the outer skeleton 10 of the filter element is most likely to be crushed and broken. Therefore, the mounting strength between the outer peripheral edge of the cartridge outer frame 10 and the base 20 can be improved by arranging the outer periphery of the engagement teeth around the outer peripheral periphery of the mounting end 110.
In another embodiment, the first connecting member 120 is a clamping groove, the plurality of clamping grooves extend inwards around the outer periphery of the mounting end 110, and the second connecting member 210 is a clamping tooth adapted to the clamping groove.
That is, the engaging teeth may be provided on the cartridge outer frame 10 or may be provided on the base 20. Preferably, the clamping teeth are arranged on the filter element outer framework 10, if the clamping grooves are arranged on the filter element outer framework 10, the mounting end 110 of the filter element outer framework 10 needs to be thickened, and therefore the processing difficulty of the filter element outer framework 10 is increased.
In one embodiment, the clamping teeth comprise a connecting end 121 and an extending end 122, the connecting end 121 is connected with the filter element outer skeleton 10, and the extending end 122 extends towards the middle of the filter element outer skeleton 10 in an arc shape; the clamping groove extends towards the middle of the base 20 in an arc shape.
The clamping teeth and the filter element outer framework 10 are integrally processed and designed.
The extending end 122 of the clamping tooth extends obliquely to the middle of the filter element outer framework 10 compared with the connecting end 121, and the extending end 122 and the mounting end 110 of the filter element outer framework 10 are arranged at intervals. Correspondingly, the clamping groove also extends to the middle of the inclined base 20 to be matched with the clamping teeth, and then when the base 20 is in spiral fit with the filter element outer framework 10, the clamping teeth are completely embedded in the clamping groove to pre-connect the base 20 and the filter element outer framework 10, and then the base 20 and the filter element outer framework 10 are further connected by adopting bonding or welding.
Specifically, the arc-shaped orientations of the plurality of clamping teeth are arranged along the same spiral direction.
That is, the installation between the cartridge exoskeleton 10 and the base 20 is simply installed by rotating, and the connection strength thereof can be ensured.
In some other embodiments, the first connector 120 and the second connector 210 may also be mated using other types. Such as a snap and detent, a threaded rotation fit, etc., without limitation.
Specifically, the cross-sectional dimension of the connecting end 121 to the extending end 122 of the snap teeth decreases. Because the connecting end 121 is connected with the mounting end 110 of the filter element outer framework 10, the cross section size of the connecting end 121 is larger than that of the extending end 122, which is favorable for improving the structural strength of the clamping teeth, and avoiding the influence on the connection strength of the filter element outer framework 10 due to the broken teeth in the connection process between the filter element outer framework 10 and the base 20.
In one embodiment, the connecting ends 121 of the snap teeth conform to the contour of the outer edge of the cartridge exoskeleton 10.
The diameter of the base 20 is consistent with that of the filter element outer framework 10, the clamping teeth are arranged to extend the outer edge of the filter element outer framework 10, the edge of the filter element outer framework 10 can be prevented from being broken, and the connection strength between the filter element outer framework 10 and the base 20 is improved.
Further, the extended ends 122 of the clamping teeth are connected to form a circle, and the center of the circle is collinear with the centers of the base 20 and the cartridge exoskeleton 10. Therefore, after the clamping teeth and the clamping grooves are installed, the filter element outer framework 10 and the base 20 are automatically centered, the fault tolerance of workers is improved, the whole stress of the nuclear-grade sealing oil filter element is more uniform, and the installation strength between the filter element outer framework 10 and the base 20 is improved.
In one embodiment, the cartridge exoskeleton 10 is bonded to the base 20 and glue fills at least the mounting gap between the first and second connectors 120 and 210.
In yet another embodiment, the cartridge exoskeleton 10 cooperates with the base 20 to form a mounting surface 220, and the cartridge exoskeleton 10 and base 20 are welded at the mounting surface 220.
Specifically, the process of bonding the outer skeleton 10 of the filter element and the base 20 through glue is as follows:
cleaning the mounting end 110 and the clamping groove of the filter element outer framework 10 to keep the surface clean;
injecting glue into the clamping groove until the glue is spread to the edge of the base 20;
each clamping tooth corresponds to the clamping groove in position, and the clamping teeth are rotated to the maximum angle, so that the extending ends 122 of the clamping teeth are completely embedded into the bottommost part of the clamping groove, and the base 20 and the filter element outer framework 10 are automatically aligned at the moment;
applying vertical pressure to the filter element outer framework 10, and placing the installed filter element outer framework 10 and the base 20 in air for standing;
and after the glue is completely solidified, the splicing between the filter element outer framework 10 and the base 20 is finished.
Specifically, the welding process of the outer framework 10 and the base 20 of the filter element is as follows:
each clamping tooth corresponds to the clamping groove in position, and each clamping tooth is at least partially embedded in the clamping groove;
rotating the filter element outer skeleton 10 to the maximum angle, so that the extending ends 122 of the clamping teeth are completely embedded into the bottommost part of the clamping groove;
the base 20 is electrified and heated to be in a plastic state capable of being pressed and welded, and the base is thermally fused with the clamping teeth and the edge of the filter element outer framework 10;
stopping heating, and placing the connected filter element outer framework 10 and the base 20 in air for cooling to finish splicing.
