Abstract

Automation of the delivery of a particulate to a tube contained in a reformer type heater with vertical tubes is disclosed and includes a hopper having an opening at the lower end. A slide gate is mounted on the hopper and selectively projects over the opening in the hopper. A box mounted below the hopper. A primary ramp is mounted in the box and underlaps the opening in the hopper. The primary ramp has an angle of inclination and extends to a lower end of the box. The primary ramp also has a screen. A cone is connected to the box proximate to one end of the primary ramp and a tube is connected to the lower end of the cone for conveying particulate to a tube loading adaptor. A dust collection cone is connected to the box underlapping the primary ramp and a discharge port is connected to the lower end of the dust collection cone. The tube loading adaptor is positioned for connection to the tube in the reformer type heater with vertical tubes. A vibrator is connected to the box.

Claims

wherein said primary ramp includes a means for allowing dust and fines to fall through said primary ramp;

a means for conveying the particulate to a tube loading adaptor, the means for conveying the particulate being connected to the box proximate to one end of said primary ramp;

a means for collecting dust and fines connected to the box underlapping said primary ramp;

wherein the tube loading adaptor is positioned for connection to the tube in the reformer type heater with vertical tubes; and

a means for moving the particulate connectable to the apparatus for automating delivery of the particulate.

2. The apparatus according to claim 1, further including a lid hinged to a top end of the hopper.

3. The apparatus according to claim 2, further including a control system, the control system comprising:

a means communicating with a reset switch mounted on the hopper for contact with the lid;

a means communicating with the means for moving the particulate wherein the means for moving the particulate comprises a means for vibrating the box;

a means communicating with a means for suspending, raising and lowering a tube loading system in the tube of the reformer type heater with vertical tubes, wherein the means for suspending, raising and lowering is positioned above the tube loading adaptor and runs internal to the tube loading adaptor; and

at least one timer in the control system.

4. The apparatus according to claim 1, further including a hopper extension piece connected to the hopper wherein said hopper extension piece comprises a chute having vertical slots.

5. The apparatus according to claim 4, further including a lid hinged to a top end of said hopper extension piece.

6. The apparatus according to claim 1, further including a baffle mounted within the hopper and at least partially projecting over the opening in the hopper.

7. The apparatus according to claim 6, wherein said baffle includes a lower angled platform for projecting over at least a portion of the opening.

8. The apparatus according to claim 6, wherein said baffle has a vertical slot for vertically positioning said baffle within the hopper.

9. The apparatus according to claim 1, wherein the hopper has a funnel shaped piece at the lower end, the funnel shaped piece defining the opening at the lower end of the hopper;

and

further including two guides attached along and beneath the funnel shaped piece for receiving and positioning the gate as a slide gate.

10. The apparatus according to claim 9, wherein the hopper has a horizontal slit aligned with the two guides;

wherein the slide gate is mounted through the horizontal slit and projects outside of the hopper for adjusting and fixing the position of the slide gate.

11. The apparatus according to claim 10, further including a mounting bracket attached to the hopper and a bolt tractable through the mounting bracket positioned for selectively fixing the position of the slide gate.

12. The apparatus according to claim 1, wherein the box includes a top off chute mounted along the top of the box and adjacent to the hopper.

13. The apparatus according to claim 1, further including a secondary ramp mounted within the hopper and within the box underlapping the opening in the hopper and overlapping said primary ramp wherein the secondary ramp has an angle of inclination transverse to said primary ramp and extends to a position staggered over a leading edge of said primary ramp.

14. The apparatus according to claim 13, wherein the secondary ramp includes an angled end piece extending up to one side of the opening in the hopper.

15. The apparatus according to claim 13, wherein the angle of inclination of the secondary ramp is fixed at 15 degrees downward.

16. The apparatus according to claim 1, wherein the angle of inclination of said primary ramp is adjustable.

17. The apparatus according to claim 1, wherein the angle of inclination of said primary ramp is preferably in the range of from 10 degrees to 30 degrees from the horizontal.

18. The apparatus according to claim 1, wherein said means for allowing dust and fines to fall through said primary ramp comprises a screen.

19. The apparatus according to claim 18, wherein the screen has a mesh size of at least one-quarter inch.
