Abstract
An improved dust collector having a housing that encloses clean-air and dirty-air chambers with an elongate non-vertical annular hollow filter with an end accommodating the flow of clean air positioned in the housing, and a nozzle connected to an air source where the nozzle is positioned so as to inject a blast of air into the filter in order to dislodge particulate accumulated on the outside of the filter. The improvement involves a turbine positioned within the filter and linkage joining the turbine with respect to the filter such that a blast of air from the nozzle turns the turbine which thereby turns the filter whereby the filter is reoriented to facilitate removal of particulate collected thereon.

In a dust collector for removing particulate from air, the dust collector including a housing enclosing clean-air and dirty-air chambers, an elongate non-vertical annular hollow filter in the housing with an end accommodating flow of clean air, and a nozzle connected to an air source for injecting a blast of air into the end to dislodge particulate from the filter, the improvement comprising:
- a turbine positioned within the filter;
- and
- linkage joining the turbine with respect to the filter such that a blast of air from the nozzle turns the turbine and thereby turns the filter,
- whereby the filter is reoriented to facilitate removal of particulate collected thereon.
In a dust collector for removing particulate from air, the dust collector including a housing enclosing clean-air and dirty-air chambers, an elongate non-vertical annular hollow filter in the housing with an end accommodating flow of clean air, and a nozzle connected to an air source for injecting a blast of air into the end to dislodge particulate from the filter, the improvement comprising a means for turning the filter whereby the filter is reoriented to facilitate removal of particulate collected thereon.
A method for cleaning a filter located in a dust collector comprising the steps of:
- positioning a turbine within the filter;
- linking the turbine to the filter;
- impacting the turbine with a blast of air thereby causing the turbine to rotate;
- and
- imparting the rotation of the turbine to the filter by means of the linkage,
- whereby the rotation causes the particulate accumulated on the filter to fall off in the collector.
