Abstract
Disclosed is a dust collector that is essentially modular in structure, thereby making it easy to transport, position and assemble by the user himself or herself. This dust collector includes one or more filter modules, a fan module operatively connectable to one end of the filter module(s), an end plate for closing the opposite end of the filter module(s), and optionally a silencer module intercalatable between the fan module and the filter module(s) to reduce the noise of the fan. In use, the dust collector can be easily upgraded whenever required by merely changing the motor, fan wheel and inlet of the fan module and/or adding one or more filter module in order to increase the filtering surface area.
Claims12
A modular dust collector comprising, in combination:
- at least one filter module, each filter module comprising:
- a filter bag-support in the form of a hollow box having a first open end, a second open end opposite to the first one, and at least one opening transverse to said first and second ends;
- and
- a filter bag detachably fixable to each of said at least one opening;
- and
- an end plate for closing the second open end of the filter bag-support of the filter module;
- and
- a fan module comprising:
- an interchangeable fan wheel rotatably mounted within a casing having an inlet connectable to a dust collecting pipe, said inlet being located in an interchangeable inlet plate mounted on said casing, and a peripheral outlet;
- an interchangeable motor mounted on a supporting flange fixed to the casing, said motor being operatively connected to the fan wheel for driving the same;
- a fan plate having an opening made therein;
- bracket means for mounting said casing, fan wheel and motor onto said fan plate with the outlet of said casing in registry with the opening of said fan plate;
- and
- fixation means for detachably fixing the fan plate to the first open end of the filter bag-support of the filter module so as to close the same, said fixation means being devised to allow fixation of said fan plate at a plurality of different angular positions relative to said at least one opening in said filter bag-support,
- wherein the interchangeable fan wheel, said interchangeable inlet plate and said interchangeable motor are replaceable with another fan wheel of a different size, another inlet plate with an inlet of different size, and another motor of a different power, respectively to accommodate additional filter modules;
- and whereby one may select only one of said angular positions to adjust the position of the inlet of the fan with respect to the dust collecting pipe so as to facilitate their connection;
- and
- then, one may operate the dust collector so that dust sucked in by said fan through said dust collecting pipe and blown into said filter module is collected into said at least one filter bag of said at least one filter module.
