The present invention relates to a dust collector, particularly relates to a dust collector capable in recollecting particulate dust from the filter barrel of the collector.
Dust collector has been used in a factory for wood or metal works to collect the dust produced, particularly the particulate dust, to clean the environment. This is even more necessary when the air flow in the factory is not good. Workers in the factory may absorb the dust and damage their health.
A conventional dust collector is shown in
Although the conventional dust collector can collect the dust produced in the factory, it is noted there is always a leakage of particulate dust from the dust bag 8 when a maintenance of the dust collector 1 to open and clean the filter barrel 7. This means a secondary pollution will be caused.
It is therefore the principle object of the present invention is to provide a dust collector which can completely collect the particulate dust in the environment without a secondary pollution.
Another object of the present invention is to provide a dust collector equipped with a particulate dust detection unit to automatically detect the volume of the particulate dust collected.
Still another object of the present invention is to provide a dust collector equipped with an alarm unit to signal a warning the particulate dust has been collected to a preset volume and in need a maintenance to clean the filter barrel.
The principle feature of the dust collector of the present invention is to provide an air suction unit to guide the air with particulate dust into the dust collector through a dust collection tube.
Another feature of the dust collect of the present invention is to provide a filter barrel having an air conduit with one end connected to the inner portion of the filter barrel and another end formed into an air outlet adaptor. A cover is used to either close or open the air outlet adaptor.
Still another feature of the dust collector of the present invention is to provide a filter net equipped with a dust clean device to shake down the particulate dust from the filter net.
Therefore, the dust collector in accordance with the present invention comprises a collector body having a dust collection tube, a dust collection barrel, a filter barrel which comprises a filter net and an air conduit with one end connected to the inner portion of the filter barrel and another end formed into an air outlet adaptor, a dust clean device and an air suction unit which drives the air with particulate dust to pass the filter net of the filter barrel and a cover used to either close or open the air outlet adaptor.
Those and other advantages, objects and features of the dust collector in accordance with the present invention will become apparent from the below detailed description of the preferred embodiment of the invention with reference to the accompanying drawings, wherein:
Referring to
A filter barrel 40 installed in the collector body 10 comprises a filter net 41 to filter the air mixed with dust and a dust clean device 42 installed in the filter barrel 40 which is operated by a handle 43 extended outward the filter barrel 40 and the collector body 10. There is an air outlet adaptor 44 formed at the lower portion of the filter barrel 40. The air outlet adaptor 44 is communicating with the inner portion of the filter net 41 of the filter barrel 40 and is also communicating with the dust collection tube 20. If the particulate dust contained in the driven air and filtered to stick on the filter net 41 reached a preset volume, the dust collector may automatically stop.
An air suction unit 50 is equipped in the collector body 10 to guide the environmental air into the collector body 10 through the dust collection tube 20. The air will be in turn driven to pass through the dust collection barrel 30 as well as the filter net 41 of the filter barrel 40. Filtered clean air will be released out of the collector body 10. It is readily to know that the air suction unit 50 can be an air pump or an electric fan.
A cover 60 can be fitted onto the air outlet adaptor 44 to either close or open the same.
A dust detection unit 70 comprises a dust detection device 71 which is installed in the collector body 10 and an alarm device 72. The function of the dust detection unit 70 is to detect the particulate dust volume filtered and contained on the filter net 41d and in the dust collection barrel 30. It is readily to know that the dust detection device 71 can be a pressure sensor and the alarm device 72 can be a LED.
When the dust collector 100 in accordance to the present invention is actuated to function the particulate dust collection, please still refer to
Referring to
When the particulate dust has been accumulated on the filter net 41 more than a preset volume, the dust collector 100 needs to operate its clean maintenance process. The cover 60 will be uncovered from the air outlet adaptor 44 and one end of the dust collection tube 20 will be fixed onto the air outlet adaptor 44. By rotating the handle 43, dust clean device 42 will be actuated to sweep and clean the filter net 41 causing the particulate dust to drop in the filter barrel 40 and then sucked into the dust collection barrel 30 through the dust collection tube 20. The filter net 41 and the filter barrel will be cleaned without a secondary pollution during the clean maintenance.
Referring to
Although the dust collector capable of recollecting particulate dust in the filtered barrel in accordance with the present invention has been described by way of preferred embodiment, it will become apparent and easily understood that changes, improvement and modifications may still be possible but without departing from the spirit of the current invention and still fallen in the protection scope as the claims of the invention.
