Pre-filtration and maintenance sensing for explosion-proof enclosures
First Claim
Patent Images
1. A maintenance sensing system for an enclosure, the maintenance sensing system comprising:
- a filter system located in an aperture in a wall of the enclosure, wherein the filter system controls air flowing into the enclosure, wherein the enclosure is suitable for explosive environments, and wherein the filter system comprises at least one enclosure coupling feature that couples to the wall of the enclosure so that the enclosure complies with industry standards for explosion-proof enclosures;
a sensor that measures an operating value of an operating parameter inside the enclosure, wherein the operating value is associated with the air flowing into the enclosure through the filter system;
a control device operatively coupled to the sensor, wherein the control device;
receives the operating value from the sensor;
determines that the operating value exceeds a threshold value; and
performs, based on determining that the operating value exceeds a threshold value, a maintenance operation to reduce the operating value of the operating parameter inside the enclosure.

Abstract
A filter system for an explosion-proof enclosure is described herein. The filter system can include a pre-filter assembly located outside the explosion-proof enclosure. The pre-filter assembly can include a pre-filter material configured to control air passing therethrough. The filter system can also include a filter assembly coupled to the pre-filter assembly. The filter assembly can further control the air received from the pre-filter assembly and passing therethrough into the explosion-proof enclosure.

19. An explosion-proof enclosure, comprising:
-
an enclosure body having an aperture that traverses therethrough; an enclosure cover coupled to the enclosure body; a filter system located in the aperture of the explosion-proof enclosure, wherein the filter system controls air flowing into the explosion-proof enclosure, and wherein the filter system comprises at least one enclosure coupling feature that couples to the explosion-proof enclosure so that the explosion-proof enclosure complies with industry standards for explosion-proof enclosures; a sensor that measures an operating value of an operating parameter inside the explosion-proof enclosure, wherein the operating value is associated with the air flowing into the explosion-proof enclosure through the filter system; and a control device operatively coupled to the sensor, wherein the control device; receives the operating value from the sensor; determines that the operating value exceeds a threshold value; and performs, based on determining that the operating value exceeds a threshold value, a maintenance operation to reduce the operating value of the operating parameter inside the explosion-proof enclosure. - View Dependent Claims (20)
