Abstract
A vibrating filter has a housing, top and bottom plates spaced vertically in an upper portion of the housing and defining an outlet chamber therebetween, at least one filter element dependent from the bottom plate into a filter chamber defined in the housing below the outlet chamber and a process liquid inlet into the filter chamber and a filtered liquid outlet from the outlet chamber. A vibrator containing an eccentrically movable mass, abuts and is energizable directly through the top plate, without need for energizing hoses or conduits within the outlet chamber. The vibrator connects by a slim depending member to the bottom plate carrying the filter elements.
Claims18
A vibrating filter for removal of unwanted solids from sticky liquids, particularly including modern base coat paint applied by means of electrostatic dip tanks to automobile bodies prior to application of a finish coat paint thereto, comprising:
- a substantially vertical housing having a removable cover at one end thereof, said housing having an inlet for process liquid to be filtered and an outlet for filtered liquid, said housing having a first annular step at said one end thereof and an annular second step spaced intermediate said one end of said housing and an opposite end thereof, said second step dividing said housing into a filter chamber and a vibrator chamber;
- first and second plates supported on said first and second steps respectively;
- a filter element in said filter chamber and fixed to and opening through said second plate and into said vibrator chamber, said second plate separating said chambers;
- and second U-section resilient rings surrounding and fitted over the periphery of said first and second plates respectively for (1) sealing said vibrator chamber from said filter chamber and from the environment outside the housing, and (2) resiliently supporting both said plates with respect to said first and second housing steps respectively;
- means rigidly fixing said first and second plates together in spaced relation, said means comprising a vibrator having a rigid hollow casing and an inertia mass movable eccentrically within said casing along an internal path in a generally upstanding plane, said vibrator casing being rigidly fixed to and abutting and protruding from the inner face of said first plate, said vibrator being spaced from said second plate, a post spanning the space between the vibrator casing and second plate, said post rigidly connecting the bottom of said vibrator casing to said second plate, said vibrator casing and post being centrally fixed to said plate.
A vibrating filter for removal of unwanted solids from sticky liquids, particularly including modern base coat paint applied by means of electrostatic dip tanks to automobile bodies prior to application of finish coat paint thereto, comprising:
- a housing;
- a top plate and a bottom plate spaced therebelow in said housing and defining an outlet chamber vertically therebetween, at least one filter element depending from said bottom plate into a filter chamber defined below said bottom plate in said housing, said housing having a process liquid inlet into said filter chamber and a filtered liquid outlet from said outlet chamber;
- a vibrator having a casing including front and rear faces and a peripheral face in turn having a flat top portion fixed flush against the underside of said top plate adjacent the center thereof, said vibrator including an inertia mass movable in a closed orbit in said casing, said orbit defining a plane at an angle to said top plate, pressure fluid inlet and outlet passages extending generally tangentially from opposite sides of said orbit up through said flat portion of said casing periphery and communicating with corresponding passages through said top plate for respective connection to a pressure fluid source and exhaust means outside said housing;
- a rigid post depending bottom of said vibrator casing and connecting same rigidly to the top of said bottom plate;
- resilient means mounting said top and bottom plates in said housing.
A vibrating filter for removal of unwanted solids from sticky liquids, particularly including modern base coat paint applied by means of electrostatic dip tanks to automobile bodies prior to application of a finish coat paint thereto, comprising:
- a housing;
- a top plate and a bottom plate spaced therebelow in the housing and defining an outlet chamber vertically therebetween, at least one filter element depending from said bottom plate into a filter chamber defined below said bottom plate in said housing, said housing having a process liquid inlet into said filter chamber and a filtered liquid outlet from said outlet chamber;
- resilient means mounting top and bottom plate to said housing;
- a casing including front and rear
- a vibrator having a casing including front and rear faces and a peripheral face in turn having a flat top portion fixed flush against the underside of said top plate adjacent the center thereof;
- a rigid post depending from the bottom of said vibrator casing and connecting same rigidly to the top of said bottom plate, said vibrator being of the kind having an inertia mass movable eccentrically therewithin to cause vibratory movement of the vibrator casing, said casing and post defining a central column fixedly joining said top and bottom plates and extending substantially vertically therebetween, the bottom half of said vibrator casing being convexly curved generally downward to in effect taper down into said post, the front and rear faces of said vibrator casing being substantially flat, the thickness of said vibrator casing between said front and rear faces being substantially less than the radius of said outlet chamber, the maximum thickness of said post being no more than the thickness of said vibrator casing, the height of the post being at least a third the height of the outlet chamber, the flat front and rear faces of the vibrator casing defining planes substantially parallel and straddling the length axis of the filtered liquid outlet from said outlet chamber, the outlet chamber having the shape of an upstanding right circular cylinder from which the filtered liquid outlet protrudes radially, the diameter of said cylinder substantially exceeding the width and thickness of said vibrator casing, the diameter of said chamber substantially exceeding the combined height of said vibrator casing and post, said at least one filter element opening through said bottom plate into said chamber behind said post, namely on the side of said post opposite said outlet, such that a flow of filtered liquid rising out of the top of the last mentioned filter element behind said post can easily and with little restriction flow upward and forward toward said outlet through the relatively wide aisles on opposite sides of said post and vibrator, so as to avoid interference with the passage of such liquid through said outlet chamber despite the central location of the vibrator and post therein.
