Abstract

A filter system and method include a filter configured to receive a first fluid mixture via an inlet. The first fluid mixture includes a first fluid and debris. The filter is shaped to separate a portion of the debris from the first fluid. A fluid control device is fluidly coupled with the filter. The fluid control device receives the first fluid from the filter and changes a characteristics of the first fluid. A conduit is fluidly coupled with the filter and a second fluid source. The conduit receives the debris from the filter and a second fluid from the second fluid source. The conduit combines the debris with the second fluid to form a second fluid mixture within the conduit. The conduit is shaped to control one or more of a pressure or a velocity within the conduit to direct the second fluid mixture through the conduit toward an outlet.

First claim

What is claimed is:

1. A filter system comprising:
a filter configured to receive a first fluid mixture via an inlet, the first fluid mixture comprising a first fluid and debris, the filter shaped to separate a portion of the debris from the first fluid;
a fluid control device fluidly coupled with the filter, the fluid control device configured to receive the first fluid from the filter and change a characteristic of the first fluid to form a second fluid within the fluid control device, the fluid control device configured to direct a first portion of the second fluid out of the fluid control device via a first outlet of the fluid control device and direct a second portion of the second fluid out of the fluid control device via a second outlet of the fluid control device; and
a conduit fluidly coupled with the filter and the fluid control device, the conduit configured to receive the portion of the debris from the filter and the second portion of the second fluid from the fluid control device,
the conduit extending along an axis and comprising a section including an increasing cross-sectional size along the axis, the conduit configured to receive the portion of the debris and the second portion of the second fluid at a location that is upstream along a direction of flow from the section including the increasing cross-sectional size, the conduit configured to combine the portion of the debris with the second portion of the second fluid within the conduit upstream of the section including the increasing cross-sectional size to form a second fluid mixture, the conduit shaped to control one or more of a pressure or a velocity within the conduit to direct the second fluid mixture through the conduit toward an outlet.

2. The filter system of claim 1 , wherein the fluid control device is configured to receive the first fluid from the filter and separate the second fluid into the first portion of the second fluid and the second portion of the second fluid.

3. The filter system of claim 1 , wherein the filter is shaped to rotate the first fluid mixture in one or more cyclonic directions in the filter.

4. The filter system of claim 1 , wherein the filter, the fluid control device, and the conduit are disposed within a common housing.

5. The filter system of claim 1 , wherein the fluid control device is disposed outside of a common housing.

6. The filter system of claim 1 , wherein the conduit is shaped to control one or more of a flow rate, direction of movement, a volumetric flow rate, a temperature, a turbulence, or rotational force of one or more of the debris, the second portion of the second fluid, or the second fluid mixture.

7. The filter system of claim 1 , wherein a portion of one or more internal surfaces of the conduit is textured to change one or more characteristics of the second fluid mixture within the conduit.

8. The filter system of claim 1 , wherein the second fluid has an energy level that is greater than an energy level of one or more of the first fluid mixture or the first fluid.

9. A method comprising:
separating a first fluid of a first fluid mixture from debris of the first fluid mixture within a filter;
directing the first fluid toward a fluid control device;
changing a characteristic of the first fluid to form a second fluid within the fluid control device;
separating a first portion of the second fluid from a second portion of the second fluid;
directing the first portion of the second fluid out of the fluid control device via a first outlet of the fluid control device and directing the second portion of the second fluid out of the fluid control device via a second outlet of the fluid control device; and
receiving the debris and the second portion of the second fluid from the fluid control device within a conduit, the conduit comprising a section including an increasing cross-sectional size along an axis, the conduit configured to receive the debris and the second fluid at a location that is upstream along a direction of flow from the section including the increasing cross-sectional size, the conduit configured to combine the debris with the second fluid to form a second fluid mixture, the conduit shaped to control one or more of a pressure or a velocity within the conduit to direct the second fluid mixture through the conduit toward an outlet.

10. The method of claim 9 , further comprising directing the second portion of the second fluid from the fluid control device via the second outlet toward the conduit to form the second fluid mixture within the conduit.

11. The method of claim 9 , further comprising rotating the first fluid mixture in one or more cyclonic directions to separate the debris from the first fluid.

12. The method of claim 9 , wherein the filter, the fluid control device, and the conduit are disposed within a common housing.

13. The method of claim 9 , wherein the fluid control device is disposed outside of a common housing.

14. The method of claim 9 , further comprising controlling one or more of a flow rate, direction of movement, a volumetric flow rate, a temperature, a turbulence, or rotational force of one or more of the debris, the second portion of the second fluid, or the second fluid mixture based on a shape of the conduit.

15. The method of claim 9 , wherein a portion of one or more internal surfaces of the conduit is textured to change one or more characteristics of the second fluid mixture within the conduit.

16. A filter system comprising:
a filter configured to receive a first fluid mixture via an inlet, the first fluid mixture comprising a first fluid and debris, the filter shaped to separate a portion of the debris from the first fluid;
a fluid control device fluidly coupled with the filter, the fluid control device configured to receive the first fluid from the filter and change a characteristic of the first fluid to form a second fluid, the fluid control device configured to separate a first portion of the second fluid from a second portion of the second fluid by directing the first portion of the second fluid out of the fluid control device via a first outlet and directing the second portion of the second fluid out of the fluid control device via a second outlet; and
a conduit fluidly coupled with the filter and the second outlet of the fluid control device, the conduit configured to receive the portion of the debris from the filter and the second portion of the second fluid from the fluid control device, the conduit comprising a section including an increasing cross-sectional size along an axis of the conduit, the conduit configured to receive the portion of the debris and the portion of the second fluid at a location that is upstream along a direction of flow from the section including the increasing cross-sectional size, the conduit configured to combine the portion of the debris with the second fluid within the conduit to form a second fluid mixture, the conduit shaped to control one or more flow characteristics of one or more of the portion of the debris, the second fluid, or the second fluid mixture within the conduit,
wherein the filter, the fluid control device, and the conduit are disposed within a common housing.

17. The filter system of claim 16 , wherein the second fluid has an energy level that is greater than an energy level of one or more of the first fluid mixture or the first fluid.

18. The filter system of claim 1 , wherein the fluid control device includes a fluid control inlet configured to receive the first fluid from the filter, the fluid control inlet fluidly coupled with both of
