Description

A kind of Anti-leakage type lid of filter

Technical field

The utility model relates to filter, and more particularly, it relates to a kind of Anti-leakage type lid of filter.

Background technology

By the process that fluid purification purifies by special device, the mode of filtration is a lot, and the system of use is also very extensive, and solid-liquid, solid-gas, bulky grain, granule are all very common.

Filtration is that liquid (or gas) in motive force or other External Force Acting low suspension liquid (or containing solid particle heating gas) is through medium, solid particle and other materials are filtered medium and retain, thus make the operation that solid and other materials are separated with liquid (or gas).

At present, the application number on market is the patent of CN201080028618.9, provides a kind of filter core being applicable to multistage filtering, such as double-stage filtering.This filter core has a tip plate configurations be made up as polyurethane of thermosets, and wherein the top of this external filter and internal ramp and bottom have at least one to be embedded in thermosets.A tip plate configurations adopts thermosets to be for the ease of manufacturing this tip plate configurations, and this tip plate configurations has the sealing of one or more sealing surfaces to seal together with the shell together with assembling with filter core.Such as, the filter liquide that the thermosets of this end plate can filter from each stage through filter core seals unfiltered liq.

But the filter in some main equipments, its lid is formed by casting of metals, and thickness is thicker, owing to being the large-sized object be cast into, therefore therefrom having a lot of gap and produces, therefore can produce seepage.In order to make up this defect, at cast outer surface coating marine glue, pour into a mould one deck resin more afterwards, but resin can be the condition of high temperature when pouring into a mould, and marine glue can be melted, still can produce leakage problems.

Utility model content

For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of Anti-leakage type lid of filter.

A kind of Anti-leakage type lid of filter, comprising lid, described lid is provided with installing hole, described lid inner surface being fitted with the metallic plate for preventing seepage.

Pass through technique scheme: when lid uses, inner surface and fluid contact, outer surface then with contacting external air, be exposed to filter outside.By the setting of metallic plate, even if there is the gap of leakage on lid, also can block fluid, anti-fluid flows out from gap.

The utility model is set to further: described cover outer surface is disposed with Waterproof glue line and resin bed.

Pass through technique scheme: by the setting of Waterproof glue line and resin bed, prevent the super outside outflow of internal flow further on the one hand, on the other hand, also prevent filter exterior materials and enter into filter interior by lid.

The utility model is set to further: it is characterized in that: described lid inner surface is provided with groove, described metallic plate is provided with the lug boss embedding groove.

Pass through technique scheme: can make in installation is the effect that metallic plate can pre-fix by with lid, the area of simultaneously fitting is larger, also can play the omnibearing effect preventing seepage.

The utility model is set to further: described metallic plate is provided with the metallic sheath embedding installing hole.

By technique scheme: be mounted on filter at lid by installing hole; now, installing hole goes out also may there is seepage, is socketed in installing hole by metallic sheath again; so just can cross and also play a protective role to installing hole, anti-fluid seepage from installing hole is gone out.

The utility model is set to further: described metallic sheath is evenly provided with some gaps.

Pass through technique scheme: by the setting in gap, just only need just can form metallic sheath to metallic plate is one time punching molded, and the existence in gap makes in installation process more tight with coordinating of bolt, serves close-connected effect.

The utility model is set to further: described metallic plate is aluminium sheet.

The utility model is set to further: described metallic plate is corrosion resistant plate.

The utility model is set to further: described metallic plate is copper coin.

Detailed description of the invention

Referring to figs. 1 through Fig. 3, a kind of Anti-leakage type lid of filter of the utility model embodiment is described further.

According to Fig. 1 and Fig. 2, the first embodiment is explained:

A kind of Anti-leakage type lid of filter 1, comprising lid 1, described lid 1 is provided with installing hole 2, described lid 1 inner surface being fitted with the metallic plate 3 for preventing seepage.

When lid 1 uses, inner surface and fluid contact, outer surface then with contacting external air, be exposed to filter outside.By the setting of metallic plate 3, even if there is the gap 9 of leakage on lid 1, also can block fluid, anti-fluid flows out from gap 9.

Described lid 1 outer surface is disposed with Waterproof glue line 4 and resin bed 5.

Pass through technique scheme: by the setting of Waterproof glue line 4 and resin bed 5, prevent the super outside outflow of internal flow further on the one hand, on the other hand, also prevent filter exterior materials and enter into filter interior by lid 1.

By Fig. 3, the second embodiment is explained.

Described lid 1 inner surface is provided with groove 6, described metallic plate 3 is provided with the lug boss 7 embedding groove 6.Described lid 1 is provided with installing hole 2, described metallic plate 3 is provided with metallic sheath 8.Described metallic sheath 8 is evenly provided with some gaps 9.

Can make in installation is the effect that metallic plate 3 can pre-fix by with lid 1, and the area of simultaneously fitting is larger, also can play the omnibearing effect preventing seepage.

Be mounted on filter at lid 1 by installing hole 2, now, installing hole 2 goes out also may there is seepage, is socketed in installing hole 2 by metallic sheath 8 again, so just can cross and also play a protective role to installing hole 2, and anti-fluid seepage from installing hole 2 is gone out.

By the setting in gap 9, just only need just can form metallic sheath 8 to metallic plate 3 is one time punching molded, and the existence in gap 9 makes in installation process more tight with coordinating of bolt, serves close-connected effect.

Metallic plate 3 can for being aluminium sheet or corrosion resistant plate or copper coin.

The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
