Multi-cyclone sediment filter

Abstract

A multi-cyclone sediment filter having a sediment bowl with a hemispherical bottom and a sump for collecting sediment, a cylindrical cyclone housing disposed above and sealingly connected to the sediment bowl, a removable and replaceable cyclone cartridge inserted into the cyclone housing, a diffuser plate sealingly connected to the cyclone cartridge and cyclone housing, a fluid inlet for introducing fluid into the cyclone housing, and a fluid outlet for discharging fluid from the cyclone housing. The cyclone cartridge inserted in the cyclone housing includes a plurality of vertically disposed inverted cone- shaped fluid cyclones, each having a small opening at a lower end and larger opening at an upper end. The cartridge has a plurality of fluid flow paths that direct fluid to the cyclones where a vortex is induced in the moving fluid. As sediment is removed from the fluid in each cyclone, it is separated out and delivered down into the sediment bowl sump, while fluid is directed upwardly and out to the fluid outlet.

Description

technical field [0001] The present invention relates generally to cyclone separators, and more particularly to a multi-pass cyclone separator and sediment filter for fluids that uses a plurality of cyclones arranged in a radial pattern to remove particulate debris from the fluid . Background technique [0002] Cyclone separators are used to separate unwanted debris from a fluid by using centrifugal force. Fluid is usually injected obliquely into the cyclone separator element, thereby creating a circulating flow. Centrifugal force acts on the debris, which is denser than the fluid in which it is suspended, pushing the denser material outward and towards the perimeter of the separation chamber. The conical shape of the separator element does not allow denser material to exit the top of the inverted cone. Instead, the substantially debris-free fluid surrounding the center of the vortex is extracted and recycled, while the debris is collected and discarded. [0003] Some cyc...

[0008] US Patent No. 4793925 to Duval et al shows a single element separator comprising a body with an inlet and an outlet that induces vortices in the fluid by driving the fluid into an inverted conical cavity .Solid particulate material falls from an orifice in the bottom of the cone. In many respects this is indistinguishable from the Tashiro et al. patent.
