Abstract

A vacuum waste removal system including a waste receiving container including a tank having an intake conduit, a dome carrying an air knife and having an outlet conduit and a filter screen removably located between an upper end of the tank and a lower end of the dome. The improvement is directed to a lift and lock arrangement interconnecting the dome with the tank. The arrangement includes a horizontal arm extending from one edge of the dome and tank to substantially the vertical axis of the container. A jack is connected with the first end of the arm while the second end connects with the dome and air knife. A conduit supplying air to the air knife passes through the connector connecting the dome with the end of the arm. The arrangement allows the dome, the conduit, and the air knife to be moved upward away from the tank a distance sufficient to allow removal and replacement of the filter. The arrangement then allows the dome, conduit and air knife to be cranked downwardly into sealed engagement with the tank. During these vertical movements, the dome is maintained aligned with the vertical axis of the cylinder.

Claims

1. In an industrial cleaning arrangement having a dust and lint collection cylinder including a tank having an air intake, a removable dome having an air outlet and a screen removably located between an outer edge of said dome and an upper edge of said tank, said arrangement comprising;

a lock and lift unit connecting with said tank at a point along the periphery thereof and with said dome at a point aligned with the vertical axis of said cylinder, said unit being operative to separate said dome from said tank by lifting said dome along said vertical axis and to seal said dome with said tank by moving said dome downward along said vertical axis into pressured contact with said upper edge of said tank;

whereby,

said dome may be raised to allow removal of said screen and lowered into sealing engagement with said tank.

2. The arrangement of claim 1 including;

a guide member associated with said cylinder, said guide member being operative to maintain said dome aligned with said tank during vertical movement.

3. The arrangement of claim 1;

wherein said lock and lift unit includes a crank jack mounting a horizontal arm.

4. The arrangement of claim 3 including;

a mounting stand connected with said periphery of said tank adjacent said upper edge, said crank jack being secured with said mounting stand.

5. The arrangement of claim 3 including;

a connector including a swivel mounting connecting said horizontal arm with said dome.

6. The arrangement of claim 1 including;

a rotating air knife carried within said dome.

7. The arrangement of claim 6 including;

an air conduit passing through said dome along said vertical axis for supplying said air knife with compressed air.

8. The arrangement of claim 7 wherein;

said lock and lift unit includes a horizontal arm and a connector connecting said arm with said dome, said air conduit passing through said connector.

9. The arrangement of claim 1 including;

a plurality of sealing members, said sealing members being operative to lock opposed flanges of said tank and said dome in air tight engagement with the periphery of said screen.

10. In an industrial cleaning arrangement for accumulating dust and lint a reservoir having a vertical axis, said reservoir including a tank having an air inlet, a dome having an air outlet, an air knife carried by said dome and a filter screen positioned between said tank and said dome, a method of separating said dome from said tank for facilitating access to said filter screen and of reuniting said dome with said tank in sealed air tight engagement;

said method comprising;

providing a substantially vertically disposed lifting member having a substantially horizontally disposed lifting arm;

providing a connector and connecting said connector with said lifting arm and with said dome along said vertical axis;

actuating said lifting member to move said connector vertically along said vertical axis; and

moving said dome first upward along said vertical axis away from and out of engagement with said tank and moving said dome second downward along said vertical axis toward and into engagement with said tank.

11. The method of claim 10 including providing said lifting member include a crank jack.

12. The method of claim 10 including;

providing a swivel connection between said lifting arm and said dome and allowing relative movement between said lifting arm and said dome during movement.

13. The method of claim 12 including;

providing an air conduit through said connection along said vertical axis and supplying said air knife with compressed air through said conduit.

14. A vacuum waste receiving container including a tank having an intake conduit, a removable dome having an outlet conduit, a filter screen located between an upper edge of said tank and a lower edge of said dome, an air knife carried by said dome and an air supply for supplying air for said air knife, the improvement comprising;

a lock and lift arrangement interconnecting said dome with said tank, said lock and lift arrangement including an arm extending from a point along the periphery of said dome to substantially the vertical axis of said container, a jack connecting with a first end of said arm, a connector having a swivel member connecting said dome with a second end of said arm along said vertical axis and a conduit passing through said connector connecting said air supply with said air knife;

whereby,

said lock and lift arrangement acts to move said dome vertically between a raised position separated from said tank and a lowered position in engagement with said tank, to allow air from said supply to communicate with said air knife and to allow relative movement between said dome and said arm during said vertical movement.
