    A filter is provided with a number of elongated filter elements disposed in a pressure vessel. Each element has a filter web extending about the length of the element and fastened at the top and the bottom. Rigid support means are provided inside the filter element in order to support the web. They extend about the length of the element and preferably extend over a part only of the circumference of the element so as to permit the web to perform a limited movement outwards and inwards in radial direction. During the operation the web is pressed against the support means by the inflowing liquid permitting a filter cake to build up at its outside while upon a backwash operation the web moves outwardly away from said support means thus loosening the filter cake. Inlet and outlet means are provided on the pressure vessel. This permits a build-up and easy removal of the filter cake without the use of a bellows type filter web.

    专利说明:

    The invention relates to the filtration of liquids, in particular to cartridge filters.
    A known filter comprising a housing with inlet and outlet nozzles for liquid, vertical filter elements installed in the housing and including a support frame and elastic filtering material, and a regeneration device with a nozzle for supplying compressed air; connected to the internal cavity of the filtering material Cl3. The known device is characterized by insufficient sludge removal efficiency and a limited service life of the filter material.
    The purpose of the invention is to increase the efficiency of removal of the precipitate rf to increase the service life of the filter material.
    This goal is achieved by the fact that in a filter comprising a housing with fluid inlet and outlet nozzles, vertical filter elements mounted in the housing and including a support frame and an elastic filtering material, and a regeneration device with a nozzle for supplying compressed air connected to the internal cavity the filtering material, the cross section of the support frame is made in the form of a polyhedron with concave edges and rounded corners.
    In addition, the reference / arcace section has 2, 3, 4, or 8 concave faces and 2, 3, 4, or 8 rounded corners.
    FIG. 1 shows the filter, a general view; in fig. 2 - filter element, longitudinal section; FIGS. 3-6 are a support frame having 2, 3, 4 or 8 rounded corners, respectively.
    The filter comprises a housing 1 with an inlet 2 port for the suspension to be filtered, an outlet 3 for the purified liquid and an opening 4 for removing filtering residues. The housing 1 is attached to the flanges 5 with a removable cover b with an air outlet pipe 7. The filter elements 8 are fixed in the collector 9. The filter element 8 contains a frame 10, which passes the substrate 11, the filter fabric 12 and the filter cake 13.
    Between the filter cloth 12 and the substrate, 11 there is a small space 14.
    The filter works as follows
    In the process of filtering, the suspension to be filtered is fed through the nozzle 2 into the filter housing 1. Under the influence of fluid pressure, the filter cloth is adjacent to the frame 10. Solid parts are deposited on the cloth 12 of the filter element 8 and form the filter cake 13. Pass through the filter cake 13, the filter fabric 12, which passes the substrate 11, the liquid passes inside the frame 10, rises up, goes to the collector 9 and leaves the filter through the exhaust 3 pipe.
    At the end of the filtration, the filter cake 13 can be dried by passing gas in the filter direction, for example, through a dry outlet pipe 7. The dried filter cake 13 is removed using compressed air or gas that is passed in the opposite direction, for example, through pipe 3 and the collector 9 The blows of compressed air push the filter cloth 12 outwardly and straighten it out. After discarding the filter cake 13 through the opening 4 in the bottom of the filter housing 1, it can be produced for the purpose of further cleaning by backwashing it with a solution of cleaning agent.
    You can use any multifaceted form of the frame, the choice of which depends on the size of the filter element, ha, the nature of the filter cloth used, etc.
    Using the proposed filter allows you to quickly and completely remove the dry filter cake without the need to use the built-in moving parts.
