Abstract

An improvement in a type of filtration apparatus which includes a housing having an inlet, an outlet, and a filter disposed between the inlet and the outlet so that fluids must flow through the filter in order to pass from the inlet to the outlet. The improvement is characterized by a first housing section with first peripheral edge and a second housing section with a second peripheral edge. One of the first peripheral edge of the first housing section or the second peripheral edge of the second housing section has a filter retaining groove. One of a rigid planar filter or a perforate rigid planar support adapted to support a filter membrane is disposed in the filter retaining groove. The first housing section and the second housing section are clamped together during use.

Claims

1. A filtration apparatus which includes a housing having an inlet, an outlet, and a filter disposed between the inlet and the outlet so that fluids must flow through the filter in order to pass from the inlet to the outlet, characterized by:

a first housing section with first peripheral edge;

a second housing section with a second peripheral edge;

one of the first peripheral edge of the first housing section or the second peripheral edge of the second housing section having a filter retaining groove;

One of a rigid planar filter or a perforate rigid planar support adapted to support a filter membrane is disposed in the filter retaining groove; and

means for clamping the first housing section and the second housing section together.

2. The filtration apparatus as defined in claim 1, wherein a clean out opening is provided in one of the first housing section and the second housing section, whereby particulate matter unable to pass through the filter is removed from the housing.

3. The filtration apparatus as defined in claim 1, wherein the inlet and the outlet are both positioned in the first housing section with a baffle positioned between the inlet and the outlet to prevent fluids from flowing directly from the inlet to the outlet, thereby enabling the second housing section to be removed to allow access for replacing the filter without having to disconnect either of the inlet or the outlet from a flow line.

4. The filtration apparatus as defined in claim 1, wherein the first housing section has a first peripheral flange, the second housing section has a second peripheral flange and the means for clamping the first housing section and the second housing section together engages the first peripheral flange and the second peripheral flange.

5. The filtration apparatus as defined in claim 4, wherein a channel form band wraps around the housing and clamps the first peripheral flange and the second peripheral flange together.

6. The filtration apparatus as defined in claim 1, wherein one of the first housing section or the second housing section has a sump, a mechanical conveyor being in communication with the sump whereby accumulated particulate matter unable to pass through the filter is removed from the housing by the mechanical conveyor, means being provided to prevent loss of fluid pressure from the housing during operation of the mechanical conveyor, such that the mechanical conveyor is able to operate without disrupting fluid flow through the housing.

7. The filtration apparatus as defined in claim 6, wherein the mechanical conveyor is an auger disposed in an auger tube which extends at an angle upwardly and outwardly from the sump, the length of the auger tube being selected to create a fluid head which prevents loss of fluid pressure from the housing during operation of the auger.
