Abstract

A movable oil and oil sludge removal apparatus which can be inserted into the manhole of a storage and process tank, the apparatus including a platform, a pump connected to the platform, two track assemblies connected to the platform, tracks connected to each track assembly to drive the track assemblies, a motor for driving the track assemblies, and an auger apparatus connected to the track assemblies for cutting the sludge and channeling the sludge to the pump intake.

Claims

1. A movable sludge pumping apparatus for insertion into a contained sludge area for pumping sludge from said contained sludge area, comprising:

a. a platform,

b. pump means connected to said platform for pumping sludge from said contained sludge area,

c. drive assembly means connected to said platform means for supporting and moving said platform means and said pump means to pump said sludge from selected areas of said contained sludge area, and

d. rotatable cutter means connected to said platform means for cutting and channeling said sludge to said pump means.

2. The apparatus of claim 1 wherein said drive assembly means is pivotally connected to said platform means.

3. The apparatus of claim 1 wherein said cutter means comprises auger means.

4. The apparatus of claim 1 wherein said drive assembly means is foldable beneath said platform means to enable said sludge pumping apparatus to be insertable into a manhole.

5. A movable sludge pumping apparatus for pumping sludge from a contained sludge area, comprising:

a. a platform,

b. pump means connected to said platform for pumping sludge from said contained sludge area,

c. drive assembly means pivotally connected to said platform means for supporting and moving said platform means and said pump means around said contained sludge area to pump said sludge from selected areas of said contained sludge area, said drive assembly means being foldable beneath said platform means to enable said sludge apparatus to be insertable into a manhole, and

d. rotatable cutter means rotatably connected to said drive assembly means for cutting and channeling said sludge to said pump means.

6. The apparatus of claim 5 wherein said cutter means comprises auger means.

7. The apparatus of claim 6 wherein said drive assembly means comprises track means to propel said sludge pumping apparatus around said contained sludge area.

8. The apparatus of claim 7 wherein motor means is connected to said track means for driving said track means.

9. The apparatus of claim 5 wherein said drive assembly means comprises track means to propel said sludge pumping apparatus around said contained sludge area.

10. The apparatus of claim 9 wherein motor means is connected to said track means for driving said track means.

11. A movable sludge pumping apparatus for pumping sludge from a contained sludge area, comprising:

a. a platform,

b. pump means connected to said platform for pumping sludge from said contained sludge area, and

c. drive assembly means pivotally connected to said platform means for supporting and moving said platform means and said pump means around said contained sludge area to pump said sludge from selected areas of said contained sludge area, said drive assembly means being foldable beneath said platform means to enable said sludge apparatus to be insertable into a manhole.

12. The apparatus of claim 11 wherein said drive assembly means comprises track means to propel said sludge pumping apparatus around said contained sludge area.

13. The apparatus of claim 12 wherein motor means is connected to said track means for driving said track means.
