Surface purveyed filtration process
View Patent ↗A filtration process are provided that facilitate a high quality, fine grade filtration without being burdened by the filter size, flushing, or plugging impediments inherent in the prior art. The filtration device used in the method is comprised of a topologic disk with a vacant circular center and a textured surface, and a conveyance disk with a vacant circular center and a grooved surface containing multiple inlet grooves and multiple outlet grooves. The textured surface of the topological disk and the grooved surface of the conveyance disk may be brought into direct contact with one another for filtration and separated from one another for flushing. At least one of the textured surface of the topological disk and the grooved surface of the conveyance disk may be rotated relative to the other prior to filtration. In one embodiment, the inlet grooves and the outlet grooves are configured in a spiral array.
1. A process for surface purvey filtration comprising the steps of:
a. connecting the textured surface of a topological disk with the grooved surface of a conveyance disk;
b. pressuring one or more fluids that contain solids into the inlet grooves of said conveyance disk, across portions of the contact area of said textured surface and said grooved surface, and out of outlet grooves of said conveyance disk, to collect said solids on said textured surface;
c. separating said textured surface of said topological disk from said grooved surface of said conveyance disk;
d. flushing said textured surface of said topological disk from said grooved surface of said conveyance disk to remove said collected solids;
e. rotating at least one of said textured surface of said topological disk and said grooved surface of said conveyance disk relative to one another; and
f. performing the steps of above in repeated cycles.
2. The process of claim 1 wherein said textured surface of said topological disk has a homogeneous and grainy finish.
3. The process of claim 1 wherein each of said inlet grooves and said outlet grooves have the same length.
4. The process of claim 1 wherein said inlet grooves and said outlet grooves are configured in a spiral array.
5. The process of claim 4 wherein said spiral array consists of said inlet grooves and said outlet grooves positioned in an alternating order such that each of said inlet grooves is directly adjacent to two outlet grooves and each of said outlet grooves is directly adjacent to two inlet grooves.
6. The process of claim 5 wherein the portion of each of said outlet grooves that is directly adjacent to one of said two inlet grooves is offset from the portion of each of said outlet grooves that is directly adjacent to the other of said two inlet grooves.
7. The process of claim 1 wherein each of said inlet grooves and each of said outlet grooves are spaced equidistant apart on said grooved surface of said conveyance disk.
8. The process of claim 1 wherein the width of each of said inlet grooves deceases from said inlet point of each of said inlet grooves to said endpoint of each of said inlet grooves, the width of each of said outlet grooves increases from said endpoint of each of said outlet grooves to said outlet point of each of said outlet grooves, and the rate of said decrease is inversely proportional to the rate of said increase.
9. The process in claim 1 wherein multiple sets of said topological disk and said conveyance disk are stacked together in an alternating order, wherein the top surface and the bottom surface of said topologic disks in the interior of said stack are textured, and wherein the top surface and bottom surface of said conveyance disks in the interior of said stack are grooved.
10. The process in claim 1 wherein at least one of said textured surface of said topological disk and said grooved surface of said conveyance disk may be rotated relative to the other prior to said direct contact with one another for filtration.
