Application number is that 200810166948.9 Chinese utility application has disclosed a kind of filter that can automatically cleaning rotation filter core.The filter core of its band hollow shaft rotation is under the double action to its outer surface cleaning by clean liquid back flush under the centrifugal action and cleaning round brush, the absorption that can prevent filter core one side impurity is piled up, but this cleaning structure obviously is not suitable for being attached on the existing candle filter.

In addition, application number is that the Chinese utility model patent of 96246113.X and 200320110635 discloses the auto purification filter that centering rotating shaft scrubbing cleaning brush is installed respectively in filter core.When needing cleaning, rotate external rotating shaft handle, make the cleaning brush rotation, can remove the impurity of cartridge surface.Yet there is following obviously limitation in above-mentioned prior art: 1) because filter housings is passed in the cleaning brush rotating shaft, therefore be difficult to guarantee not have leak, be not suitable for poisonous, inflammable medium; 2) cleaning brush has occupied whole space in the filter core, has increased the resistance when fluid flows, and is not suitable for large diameter filter core.

The utility model content

The purpose of this utility model is: at the shortcoming that above-mentioned prior art exists, propose a kind of self-cleaning filter that does not have leakage and compact conformation, thereby can satisfy the demand of poisonous inflammable medium and big specification filtration.

In order to reach above purpose, self-cleaning filter of the present utility model comprises the housing with import and outlet, the barrier film that is separated out power drive chamber, bottom and filter chamber, middle and upper part body is housed in the described housing, and described filter chamber body is equipped with and is separated out the tubular element that filter chamber and outlet filtration chamber are treated in import; The track rotating disk that drives with the coaxial track of tubular element brush rotating disk and power set is equipped with in the inboard of described barrier film and the outside respectively; The rotation active shaft coupling coaxial with external gear is equipped with at peripheral at least one place of described track rotating disk, described track brush rotating disk and described active magnetic shaft coupling correspondence position are equipped with the coaxial passive magnetic shaft coupling of brush holder support with the track brush, have the bristle that contacts with the tubular cartridge surface on the described brush holder support; Described external gear and the ring gear engagement that is fixed on the barrier film outside, the center of circle of described ring gear is positioned on the axis of described tubular filter core.

When driven by motor track rotating disk rotates, will drive the active shaft coupling and revolve round the sun thereupon, be somebody's turn to do the active shaft coupling simultaneously under inside and outside gear meshing effect, also around self axis rotation.Under magneticaction, driven shaft coupling will drive track brush and initiatively shaft coupling revolution and rotation synchronously, thereby brush cleaning along the inner surface of tubular filter core.Because therefore the ingenious magnetic shaft coupling that adopted of the utility model has been guaranteed not have to leak, suitable special type of filtering poisonous inflammable medium is filtered; And reasonably the revolution motion mode that combines with rotation not only makes and track brush configuration compactness can not increase filtration resistance, and no matter the filter core internal diameter is much all can effectively clear up.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is the structural representation of an embodiment of the utility model.

The specific embodiment

Embodiment one

The self-cleaning filter of present embodiment as shown in Figure 1, its tank-like shell with cover 11 middle and lower parts have import A and the outlet B.The horizontal barrier film 6 that is separated out power drive chamber, bottom and filter chamber, middle and upper part body is equipped with in bottom in the housing 11.Filter chamber's body is equipped with and is separated out the vertical tubular element 10 that filter chamber (directly being communicated with import A) and outlet filtration chamber (directly being communicated with outlet B) are treated in import.The track rotating disk 2 that the inboard of barrier film 6 tops and the outside of below drive by coaxial track brush rotating disk 8 of bearings and vertical tubular element 10 and motor 1 (as power set) respectively.Motor 1 is installed in tank-like shell 11 belows, and the track rotating disk of installing by the vertical rotating shaft and the level of output 2 is in transmission connection.The rotation vertical active shaft coupling 5 coaxial with cylinder external gear 3 is equipped with at periphery one place of track rotating disk 2, and track brush rotating disk 8 and magnetic shaft coupling 5 correspondence positions initiatively are equipped with the coaxial passive magnetic shaft coupling 7 of brush holder support with the track brush.Initiatively have 0.2-0.6 millimeter magnetic gap respectively between magnetic shaft coupling 5, passive magnetic shaft coupling 7 and the barrier film 6,, constitute contactless shaft coupling structure though both not directly contacts under the effect of the magnetic line of force, are synchronized with the movement maintenance.Has the radial bristle 9 that contacts with tubular filter core 10 inner surfaces on the brush holder support.External gear 3 and ring gear 4 engagements that are fixed on barrier film 6 outsides, the center of circle of this ring gear 4 is positioned on the axis of tubular filter core 10.One side of barrier film 6 is installed the sewage draining exit C that leads to outside the tank-like shell 11 down.
