Candle filter is a kind of equipment being widely used in the numerous areas such as environmental protection, purification.During work, fluid reaches required technique object through filter element filtering.But after filtering, cartridge surface stockpiles filter residue or dirt unavoidably, makes its filter efficiency reduce, even loses efficacy.In order to address this problem, backpressure flushing is usually taked to reach cleaning object.But to retain in filter core the adhesive force showing every bit inconsistent due to dirt lime-ash, and when backpressure flushing, when cartridge surface point is by pressure penetration, other places pressure reduction cannot effectively be set up, be therefore difficult to the object reaching cleaning comprehensively.

Application number be 200810166948.9 Chinese invention patent application disclose a kind of can the filter of self-cleaning rotating filter element.Under the double action that filter core that its band hollow shaft rotates cleans its outer surface in the clean liquid back flush be centrifuged under power effect and clean round brush, can prevent the absorption of filter core side impurity from piling up, but this cleaning structure is obviously not suitable for being attached on existing candle filter.

In addition, application number is that the Chinese utility model patent of 96246113.X and 200320110635 individually discloses the self-cleaning filter installing centering rotating shaft scrubbing cleaning brush in filter core.When needing clean, rotate external rotating shaft handle, cleaning brush is rotated, the impurity of cartridge surface can be removed.But there is following obviously limitation in above-mentioned prior art: 1) because cleaning brush rotating shaft is through filter housings, is therefore difficult to ensure No leakage, is not suitable for poisonous, inflammable medium; 2) cleaning brush occupies whole space in filter core, increases resistance during fluid flowing, is not suitable for large diameter filter core.

Summary of the invention

The object of the invention is to: the shortcoming existed for above-mentioned prior art, propose the self-cleaning filter of a kind of No leakage and compact conformation, thus the demand of poisonous inflammable medium and large gauge filtration can be met.

In order to reach above object, self-cleaning filter of the present invention comprises the housing with import and outlet, the barrier film being separated out bottom power drive room and middle and upper part filter chamber body is housed in described housing, and described filter chamber body is equipped with and is separated out import and treats filter chamber and export the tubular element filtering chamber; The inner side and outer side of described barrier film is equipped with the track rotating disk that the track brush rotating disk coaxial with tubular element and power set drive respectively; The rotation coaxial with external gear initiatively shaft coupling is equipped with at least one place of periphery of described track rotating disk, described track brush rotating disk and described active magnetic shaft coupling correspondence position are equipped with the passive magnetic shaft coupling coaxial with the brush holder support of track brush, described brush holder support have the bristle contacted with tubular cartridge surface; Described external gear engages with the ring gear be fixed on outside barrier film, and the center of circle of described ring gear is positioned on the axis of described tubular filter core.

When driven by motor track turntable rotation, revolved round the sun by drive active shaft coupling, this active shaft coupling is under the engagement of internal-external gear simultaneously, also around own axes rotation thereupon.Under magneticaction, drive track brush and initiatively shaft coupling synchronously revolve round the sun and rotation by driven shaft coupling, thus brush cleaning along the inner surface of tubular filter core.Have employed magnetic shaft coupling because the present invention is ingenious, because this ensure that No leakage, the special type being applicable to the inflammable medium of filtering poisonous is filtered; And the motion mode that to combine with rotation of reasonably revolving round the sun not only makes track brush configuration compact, can not increase filtration resistance, and no matter filter core internal diameter is much all can effectively clear up.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, the present invention is further illustrated.

Fig. 1 is the structural representation of one embodiment of the invention.

Detailed description of the invention

Embodiment one

As shown in Figure 1, its tank-like shell 11 middle and lower part with cover has import A and outlet B to the self-cleaning filter of the present embodiment.The flat septum 6 being separated out power drive room, bottom and middle and upper part filter chamber body is equipped with in bottom in housing 11.Filter chamber's body is equipped with and is separated out import and treats filter chamber (be directly communicated with import A) and export the vertical tubular element 10 filtering chamber (be directly communicated with and export B).The track rotating disk 2 that inner side above barrier film 6 and the outside of below drive respectively by the coaxial track brush rotating disk 8 of bearings and vertical tubular element 10 and motor 1 (as power set).Motor 1 is arranged on below tank-like shell 11, and the track rotating disk 2 installed by vertical rotating shaft and the level of output is in transmission connection.The vertical active shaft coupling 5 of the rotation coaxial with cylindrical external gear 3 is equipped with at periphery one place of track rotating disk 2, and track brush rotating disk 8 and active magnetic shaft coupling 5 correspondence position are equipped with the passive magnetic shaft coupling 7 coaxial with the brush holder support of track brush.Active magnetic shaft coupling 5, there is between passive magnetic shaft coupling 7 and barrier film 6 0.2-0.6 millimeter magnetic gap respectively, although both directly do not contact, under the effect of the magnetic line of force, maintenance is synchronized with the movement, forms contactless coupling structure.Brush holder support has the radial bristle 9 contacted with tubular filter core 10 inner surface.External gear 3 engages with the ring gear 4 be fixed on outside barrier film 6, and the center of circle of this ring gear 4 is positioned on the axis of tubular filter core 10.The side of barrier film 6 installs the sewage draining exit C led to outside tank-like shell 11 down.
