The present invention relates to a multi-functional wet vacuum cleaner, and more specifically, to a multi-functional wet vacuum cleaner that is mounted on a waste oil storage drum to absorb, collect, and remove waste cutting oil of machine tools, hydraulic oil residue of hydraulic devices, and residues from oil generated during the production of metal products such as bolts, screws, nails, and the likes, and has ability to clean a large volume of wastes.
A conventional wet vacuum cleaner has a disadvantage in that it is inconvenient since a user has to clean while emptying the cleaner several times due to its small capacity when the cleaner performs wet cleaning with respect to waste cutting oil of machine tools, hydraulic oil residue of hydraulic devices, and residues from oil (hereinafter, called ‘waste oil’) generated during the production of metal products such as bolts, screws, nails, and the likes.
Therefore, in order to solve the above problem, as illustrated in
According to the cleaning method, a suction unit 21 of the vacuum induction device 20 is mounted in an upper opening 12 of a waste oil storage drum 10, an output hose 31 of an air compressor 30 is connected to a supply unit 22 of the vacuum induction device 20, and a suction pipe 14 is connected to an upper inlet 13 of the waste oil storage drum 10.
Moreover, in a case in which the air compressor 30 is operated, high-pressure air is injected through the output hose 31, and the injected high-pressure air is discharged to an outlet 23 by an internal structure of the vacuum induction device 20, so that the suction unit 21 sucks the air.
As the air in the waste oil storage drum 10 is discharged through the outlet 23 by the suction operation of the suction unit 21, the inside of the waste oil storage drum 10 is changed into a vacuum state while the pressure lowers.
As described above, when the inside of the waste oil storage drum 10 is in a vacuum state, a suction pipe 14 connected to the inlet 13 performs a suction operation due to a pressure difference with the outside to suck waste oil 41 accommodated on a tray 40.
Here, the tray 40 is a container that is integrally mounted on the machine tool mentioned above to store the discharged waste oil, and the suction pipe 14 is a pipe that a user holds with the hand to suck the waste oil stored in the tray 40.
Accordingly, the waste oil 41 sucked through the suction pipe 14 is introduced and stored into the waste oil storage drum 10 through the inlet 13.
The conventional art has improved cleaning ability. However, the conventional art increases additional costs due to the use of the air compressor 30 or has a limitation in carrying and storing. Moreover, the conventional art has additional disadvantage in that the vacuum induction device 20 has output loss due to the air discharged to the outside and it causes a lack of capacity of the air compressor 30.
The present invention has been made to solve the above-mentioned problems occurring in the prior arts, and it is an object of the present invention to provide a multi-functional wet vacuum cleaner that is mounted on a waste oil storage drum to absorb, collect, and remove waste cutting oil of machine tools, hydraulic oil residue of hydraulic devices, and residues from oil generated during the production of metal products such as bolts, screws, nails, and the likes, and has ability to clean a large volume of wastes.
