SELF-PURIFYING FILTER Russian patent published in 2006 - IPC B01D29/64 

FIELD: different branches of industry; production of the self-purifying filters.

SUBSTANCE: the invention is pertaining to the devices for filtration of the liquid mediums, in particular, to the self-purifying filter and may be used in different branches of industry, where the effective purification of the liquid mediums from the mechanical impurities is required. The self-purifying filter contains: the body divided by the filtering partitions into the chambers of the source and purified liquids coupled accordingly with the inlet and outlet fitting pipes; the fixed on the hollow arbor component of purification of the filtering partitions, in the lateral surface of which there is a hole communicating through the purifying component with the chamber of the source liquid. The purifying component is made in the form of the half-closed vane, the open side of which is facing the filtering partition. The hole on the lateral surface of the hollow arbor is made in the place of the purifying component fixation with provision of communication of the indicated hole with the cavity of the half-closed vane. One end of the hollow arbor arranged in the body of the filter is made with the shut butt, and other end of the hollow arbor is made with the open butt providing withdrawal of the pollutions. The filter contains the annular collector mounted in the body with formation of the ring-type channel between the internal surface of the body and the external surface of the annular collector made with the tangential partitions and the guiding slits arranged on the circumference with the even pitch. The filter can have the inlet fitting pipe mounted tangentially to the filter body, which is made cylindrical. The filter can contain: the additional filtering partition and in this case the body is divided by the filtering partitions into the chamber of the source liquid and two chambers of the purified liquid arranged symmetrically in respect to the chamber of the source liquid, and the vane of the mobile purifying component is made with two open sides facing the planes of the filtering partitions; the additional filtering partition and the additional purifying component made in the form of the half-closed vane. At that the body is parted by the filtering partitions into the chamber of the source liquid, the intermediate chamber and the chamber of the purified liquid arranged sequentially above the chamber of the source liquid. In the lateral surface of the hollow arbor there is an additional hole communicating through the additional purifying component with the intermediate chamber. The technical result of the invention is the increased efficiency of the filter operation.

EFFECT: the invention ensures the increased efficiency of the filter operation.
