ABSTRACT:
FIELD OF THE INVENTION
This invention relates generally to dust collectors and, more particularly, to a portable heavy-duty dust collector.
BACKGROUND OF THE INVENTION
Many commercial woodworking or cabinet shops have relatively effective dust collection systems. However, such systems are elaborate, with a significant cost for each work station being serviced. These systems tend to include a large centrifugal dust collector, which has a substantially cylindrical shape and is between 5 to 8 feet high. As such, a heavy-duty centrifugal dust collector is very heavy and thus not portable. Accordingly, each work station has a dust hose tube connected to the large centrifugal dust collector, as the dust collector cannot be moved between work stations.
Such systems are not readily available to an individual woodworker who has his equipment in a home basement or garage. Among the reasons are size, complexity and costs. Similarly, such systems are impractical for contractors building a house, for example, as the dust collector cannot be easily moved or carried to the jobsite. Also, such systems are not easily expanded to accommodate new equipment brought into the shop.
Accordingly, it is an object of the invention to provide a heavy-duty portable dust collector.
SUMMARY OF THE INVENTION
In accordance with the present invention, an improved dust collector is employed. The dust collector includes a main housing, a dust inlet disposed on the main housing, an air outlet disposed on the main housing, and an inclined filter disposed within the main housing and between the dust inlet and the air outlet. Preferably, the filter is pleated. The dust collector may also include a removable bin disposed within the main housing and preferably disposed below the filter. A seal may be disposed between the bin and the main housing. Similarly, the dust collector may also include a removable liner disposed within the main housing and preferably disposed below the filter. A seal may be disposed between the liner and the main housing. A baffle may be disposed within the main housing and preferably disposed between the filter and the dust inlet.
The main housing may comprise a bottom portion and a top portion pivotally attached to the bottom portion. The dust inlet is preferably disposed on the top portion. Similarly, the air outlet is preferably disposed on the top portion. The filter is also preferably disposed within the top portion.
Additional features and benefits of the present invention are described, and will be apparent from, the accompanying drawings and the detailed description below.
