Abstract
The utility model discloses a filtering cartridge of a filter, which comprises a skeleton, a filtering net and a fixing device, and is characterized in that the skeleton is provided with liquid passing holes, the section of the skeleton adopts waveform folded curve structures which are evenly distributed on the circumference, and the filtering net has a consistent shape with the skeleton and is arranged together with the skeleton. High-pressure liquid runs through the filtering net and the skeleton, thus realizing the filtering; as the shapes of the filtering net and the skeleton are consistent, the filtering net can bear larger pressure difference under the support of the skeleton, thus greatly improving the anti-pollution capacity of the filtering net; and compared with the filter filtering cartridge with a cylindrical skeleton and a cylindrical filtering net, the filtering cartridge of the utility model has increased effective filtering area due to the folded curve shape.
Description
Technical field
The utility model relates to a kind of filter element, relates in particular to a kind of hydraulic support filter element.
Background technology
Existing filter element mainly contains cylinder frame and joins cylinder leaching net and cylinder frame and join folding two kinds of forms of filter screen.
Figure 3 shows that cylinder frame joins the cylinder leaching net form, skeleton is a drum, and filter screen is a drum also, and filter screen is close on the skeleton.Though this filter element can bear big pressure, filter area is less.
Figure 4 shows that cylinder frame joins folding filter screen, skeleton is a drum, and filter screen is folded up and is attached on the skeleton.Though this filter element has strengthened filter area, because the skeleton employing is cylindric, folding filter screen is easy to be crushed or presses off and splits, and the pressure differential that can bear is little, and the life-span is low.
The utility model content
Join the little problem of cylinder leaching net filter area and join folding filter screen with cylinder frame and bear the defective that pressure differential is little, the life-span is low in order to solve existing filter element cylinder frame, the purpose of this utility model provide a kind of filter area greatly, filter element that bearing capacity difference ability is strong.
The purpose of this utility model is achieved through the following technical solutions:
A kind of filter element comprises skeleton, screen pack and fixture, and described skeleton has liquid-through hole, and skeleton section has adopted the folding curvilinear structures of the waveform that is distributed in circumference, and screen pack is consistent with frame configuration and be installed together.
Further, the utility model can also be by the following technical solutions:
Described screen pack is installed in the skeleton outside.
Described screen pack also can be installed in the skeleton inboard.
Described screen pack is formed by stacking by the single or multiple lift screen pack.
Filter element described in the utility model, because skeleton adopts the folding curvilinear structures of the waveform that is distributed in circumference, avoided stress to concentrate and the hydraulic system pressure fluctuation is drawn badly to the fatigue that filter core causes, screen pack is consistent with frame configuration, having guaranteed has increased filter area under the prerequisite that does not increase filter volume.
Hydraulic support filter of the present utility model is compared with the filter of comparable size, and water environment capacity is improved, and has prolonged the life-span of filter element, has improved anti-fatigue ability.

The specific embodiment
As shown in Figure 1 and Figure 2, filter element of the present utility model, comprise skeleton 1, screen pack 2, end cap 3, swivel nut 4, seal 5, skeleton 1 section configuration is for folding the equal portion of curve shape on circumference, have liquid-through hole above the skeleton, screen pack 2 curve shapes are consistent with skeleton 1, are installed in skeleton 1 outside or in skeleton 1 inboard, for the intensity and the precision that improve screen pack, screen pack can multilayer stack.
On the swivel nut 4 seal can be installed, swivel nut 4 can also can adopt welding with being threaded with skeleton 1.
On the end cap 3 seal can be installed, end cap 3 can be with being threaded with skeleton 1.
3 of screen pack 2 and swivel nut 4 and end caps can adopt fluid sealant to fix.
According to the flow direction of filtered fluid, filter element of the present utility model can adopt outer go out in advancing or in the two kinds of filter types that advance to go out.Served as filtrate flow to from inside to outside the time, skeleton is in the outside of screen pack; Served as filtrate flow to from outside to inside the time, skeleton is in the inboard of screen pack.
Figure 1 shows that to have served as filtrate flow to from outside to inside the time that liquid medium enters in the filter by screen pack 2 and skeleton 1 through inlet, flow out from liquid outlet then, be filtered off thing and stay screen pack 2 outsides,, can select the screen pack of corresponding filtering accuracy for use according to required filtering accuracy.The utility model filter skeleton 1 has adopted folding curve shape to be distributed on the circumference, and screen pack 2 is consistent with skeleton 1 shape, and the pressure that screen pack can be born strengthens, and water environment capacity improves greatly, increase filter area simultaneously, prolonged the life-span of filter element.
The above; it only is the preferable specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; variation or the replacement based on this structure that can expect easily all should be encompassed within the protection domain of the present utility model.
Claims (4)
1. filter element, comprise skeleton (1), screen pack (2) and fixture, it is characterized in that: described skeleton has liquid-through hole, and skeleton section has adopted the folding curvilinear structures of the waveform that is distributed in circumference, and screen pack is consistent with frame configuration and be installed together.
2. filter element according to claim 1 is characterized in that: described screen pack is installed in the inboard of skeleton.
