Abstract

An industrial vacuum cleaner, having a structure in the form of a trolley with a platform (1) on wheels (2) supporting a base (3) on which is seated an electric motor (4) connected to a radial compressor or vacuum pump (5). Two horizontal tubes (16) are connected to the front of the platform (1) and joined by two crossbars (17). At the extremities of the two horizontal tubes (16) there are casters (38). Both crossbars (17) are connected to two vertical tubes (18 and 19) of the same height, with U-shaped sockets (20 and 21) at the top end. These U-sockets are provided for slotting in segments of coaxial axle pins (22 and 23) which are placed on diametrically opposite sides of the drum (9). There are also handles (24) on either side of the drum.

Claims

1. An industrial vacuum cleaner for removing particles from a surface, the industrial vacuum cleaner comprising:

means for suctioning air;

a platform supporting said suctioning means;

a tipping drum having an inlet and an outlet and an outer surface, said tipping drum being formed to receive air with particles from the surface through said inlet;

means for cleaning the air of the particles and including a filter element in said tipping drum arranged between said inlet and said outlet, said filter element being formed to remove the particles from the air when the air passes through said filter element;

tubular means for connecting said outlet with said suctioning means so that the air passes from said inlet through said filter element and out said outlet and then through said tubular means to said suctioning means when said suctioning means suctions the air; and

means for pivotally supporting said tipping drum by said platform and including two U-shaped socket elements and two pin elements pivotally fittable with said U-shaped socket elements, two of said U-shaped socket and pin elements being attached to said outer surface of said tipping drum and arranged diametrically opposite from each other, and the other two of said elements being supported by said platform.

2. The industrial vacuum cleaner as defined in claim 1, wherein said suctioning means includes at least one electrical motor and at least one vacuum pump drivable by said one electrical motor.

3. The industrial vacuum cleaner as defined in claim 1, wherein said suctioning means includes at least one electrical motor and at least one radial compressor drivable by said one electrical motor.

4. The industrial vacuum cleaner as defined in claim 1, wherein said pin elements extend horizontally outward from said tipping drum and diametrically opposite from each other and coaxial with each other, said U-shaped socket elements being upwardly open and arranged so that said pin elements are simultaneously pivotally fittable into said U-shaped socket elements,

5. The industrial vacuum cleaner as defined in claim 1, wherein said platform has a front side facing said tipping drum, said pivotally supporting means further including two tubes horizontally extending from and connected to said front side, two crossbars joining said horizontal tubes together, two vertical tubes having upper ends, each of said vertical tubes extending from and connecting a respective one of said crossbars and having a height equal to each other, two of said elements being connected to a respective two of said upper ends.

6. The industrial vacuum cleaner as defined in claim 1;

further comprising;

a control panel; and

means for supporting said control panel including a vertical frame having an upper horizontal portion, said frame being attachable to said platform and said control panel being mountable on said upper horizontal portion.

7. The industrial vacuum cleaner as defined in claim 1, further comprising:

a plurality of handles mounted on said tipping drum.

8. The industrial vacuum cleaner as defined in claim 1, wherein said tipping drum has a central area located in a horizontal plane, said inlet being arranged above said central area;

further comprising;

an internal shield extending inward of said tipping drum and arranged to direct said air passing through said inlet downward.

9. The industrial vacuum cleaner as defined in claim 1;

further comprising;

hose means connectable with said inlet and a suction element such that air is passable from said suction element through said hose means and to said inlet.

10. The industrial vacuum cleaner as defined in claim 1, further comprising:

locking means for locking said pivotally supporting means such that said tipping drum becomes locked in a vertical position preventing pivotable movement of said tipping drum.

11. The industrial vacuum cleaner as defined in claim 1, wherein said drum has a volume to hold contents and has an opening and a movable cover closing said opening, said outlet being arranged in said cover, said cover being movable away from said opening for emptying said contents through said opening.

12. The industrial vacuum cleaner as defined in claim 11, wherein said filter element is formed with an upper brim, said drum being formed to receive said brim around said opening such that said cover is movable to close said opening on top of said brim, said cleaning means also including a basket holder housing said filter element to prevent said filter element from blocking said outlet during suction.

13. The industrial vacuum cleaner as defined in claim 12, wherein said tipping drum has a circular cross-section, said filter element being formed as a cloth bag, said brim being bendable, and said basket holder being cylindrically shaped.

14. The industrial vacuum cleaner as defined in claim 1, further comprising:

a base mounted on said platform and supporting said suctioning means, said base having an inlet opening connectable with said tubular means and having an outlet opening for discharging the air and having passages from said suctioning means to said inlet and outlet openings.

15. The industrial vacuum cleaner as defined in claim 14, wherein said base has sides, further comprising:

a plurality of noise suppressors interspersed along said sides between said suctioning means and said inlet and outlet openings.

16. The industrial vacuum cleaner as defined in claim 14, wherein said tubular means includes a first upturned tubular elbow connectable with and extendable outward and upward from said inlet opening, a second upturned tubular elbow connectable with and extendable outward and upward from said outlet opening, and a tubular flexible hose connectable between said first upturned tubular elbow and said tipping drum outlet.

17. The industrial vacuum cleaner as defined in claim 1, further comprising:

means for rolling the industrial vacuum cleaner including a plurality of wheels and casters supporting said platform.

18. The industrial vacuum cleaner as defined in claim 17, wherein said platform has a front side facing said drum;

and further comprising;

two tubes extending horizontally from said front side and having an end portion spaced furthest from said front side, one of said casters mounted to a respective one of said two tubes.

19. An industrial vacuum cleaner for removing particles from a surface, the industrial vacuum cleaner comprising:

means for suctioning air;

a platform supporting said suctioning means;

a tipping drum having an inlet and an outlet, said tipping drum being formed to receive air with particles from the surface through said inlet;

means for cleaning the air of the particles and including a filter element in said tipping drum arranged between said inlet and said outlet, said filter element being formed to remove the particles from the air when the air passes through said filter element;

tubular means for connecting said outlet with said suctioning means so that the air passes from said inlet through said filter element and out said outlet and then through said tubular means to said suctioning means when said suctioning means suctions the air;

means for pivotally supporting said tipping drum by said platform and including two U-shaped socket elements and two pin elements pivotally fittable with said U-shaped socket elements, two of said U-shaped socket and pin elements being attached to said tipping drum and arranged diametrically opposite from each other, and the other two of said elements being supported by said platform; and

locking means for locking said pivotally supporting means such that said tipping drum becomes locked in a vertical position preventing pivotable movement of said tipping drum, said locking means including a hinged latch pivotally connected to one of said U-shaped socket and pin elements, and a receiving element connected to a second of said U-shaped socket and pin elements and arranged for receiving said hinged latch for locking said latch into position.
