Pipe Conveyor for Coke Transfer

Posted in: , on 25. May. 2014 - 11:25

Pipe conveyor for coke transfer from Coke Ovens to Blast Furnace Stock House

Sir,

Our's is steel cord belt 1000 N/mm strength, 300 mm pipe dia, 1200 Mtr long for transportation of coke 34 mm to 80mm size @ 150 to 200 tons per hour from coke ovens to Blast Furnace no-5. Most often we face the problem of over filling from the previous belt and jamming in pipe conveyors. Sometimes belt joint got opened up to 90% width and identified in the mid length of panels. Further shifting to head end being risky, we had to cut panels and join by hot vulcunising there itself. It's having hydraulic drive.

We request your valuable suggestions to overcome these problems. Further please indicate

1. whether belt can be driven in opposite direction to bring to nearest flat portion

2. Whether panels can be fixed by bolting to the structure for quick shifting at timesof need.

3. Any automatic/ self traing idler to keep overlap always at the top in drive and bottom in driven side.

4. Any other automation system to be incorporated to smart operation.

Thanks,

Pipe Conv. Design Improvements

Dear Mr. Roy,

your post was moved and made a new thread due to its content deviating from prevoius thread.

Concerning your requests:

1) this should be a primary design feature of your plant, thus to be checked in op. manuals etc. if possible (motor controller, holdbacks, scrapers, idler frame adaptation, etc.)

2) to be checked by resp. design engineer for position stability under load, if due to mismatch / assembly tolerances & deviations a misplacement occurs, the belt will lose track and / or rotate

3) pls. inquire at reputable pipe belt equipment / systems suppliers, there's such solutions but to my knowledge = proprietary design and in any case adapted to specific utilization case

4) see 3)

List = just shortlist of first thoughts, may be improved by other members input. However, due to size of planned alöterations, the professional involvement of a knowledgeable specialist re consultant seems appropriate.

Regards

R.

Your problem seems to boil down to an overloaded belt. Larry Nordell might be able to improve the seam rotation aspects but if residual charge remains in the tube it is quite likely to settle and constipate your operations. If your conveyor wasn't a home made effort then it likely the original design was up to specification, if anybody at your end even checked? Consequently I suggest you examine some way of expelling the residual charge (this is very difficult although possible) or controlling the feed more accurately to achieve an acceptable cut off level.
