Filter device for use with machine
View Patent ↗Solutions for improving efficiency of a filter device for use with a machine requiring clean airflow are disclosed. In one embodiment, the filter device includes: a filter housing about an airflow inlet of the machine, wherein the filter housing comprises an air-permeable filter media configured to filter particles from multi-directional airflow moving through a substantial portion of the filter housing into the airflow inlet.
1. A filter device for use with a machine, the filter device comprising:
a filter housing about an airflow inlet of the machine, wherein the filter housing substantially comprises an air-permeable filter media configured to filter particles from a multidirectional airflow moving through a substantial portion of the filter housing into the airflow inlet, wherein a portion of the filter housing directly contacts a ground surface.
2. The filter device of claim 1 , wherein the filter housing has a substantially semi-spherical shape.
3. The filter device of claim 1 , wherein the filter housing has a substantially geodesic dome shape.
4. The filter device of claim 1 , wherein the filter housing is flexible.
5. The filter device of claim 1 , further comprising a vibration device for vibrating the filter device and removing particles on the air-permeable filter media.
6. The filter device of claim 1 , wherein the air-permeable filter media includes at least one of: a glass-fiber material or a polymer-synthetic material.
7. The filter device of claim 1 , wherein the air-permeable filter media includes a hydrophobic membrane material.
8. The filter device of claim 1 , wherein the air-permeable filter media further includes a hydrophobic coating.
9. The filter device of claim 1 , wherein the air-permeable filter media includes a multi-layered fabric.
10. A machine, the machine comprising:
an airflow inlet; and
a filter housing about the airflow inlet of the machine, wherein the filter housing substantially comprises an air-permeable filter media configured to filter particles from a multidirectional airflow moving through a substantial portion of the filter housing into the airflow inlet, wherein a portion of the filter housing directly contacts a ground surface.
11. The machine of claim 10 , wherein the filter housing has a substantially semi-spherical shape.
12. The machine of claim 10 , wherein the filter housing has a substantially geodesic dome shape.
13. The machine of claim 10 , wherein the filter housing is flexible.
14. The machine of claim 10 , further including a vibration device for vibrating the filter housing and removing particles on the air-permeable filter media.
15. The machine of claim 10 , wherein the air-permeable filter media includes at least one of: a glass-fiber material and a polymer-synthetic material.
16. The machine of claim 10 , wherein the air-permeable filter media includes a hydrophobic membrane material.
17. The machine of claim 10 , wherein the air-permeable filter media further includes a hydrophobic coating.
18. The machine of claim 10 , wherein the air-permeable filter media includes a multi-layered fabric.
19. The filter device of claim 1 , wherein the portion of the filter housing includes supporting structures for directly contacting the ground surface.
20. The machine of claim 10 , wherein the portion of the filter housing includes supporting structures for directly contacting the ground surface.
