Unplugging a Pneumatic Tanker by Reversing the Flow(Sucking it Back). Blow Baby Blow
Вставка
- Опубліковано 15 чер 2018
- This video shows being plugged but clearing the line by sucking the product back into the first empty hopper. The principle behind it is like a weather system...high pressure runs toward low pressure. Once the tank with zero psi in it is rapidly opened and closed..the product in the high pressure line is drawn back eventually clearing the plug. Yes. Its obviously better not to plug but this product is heavy, dense and has far to go. As one hopper goes empty, product falls in from an adjacent hopper dropping in too much limestone too fast for the line to handle. Watch your gauges. Truckin's the Life when you know how to do it.
This video saved my day haha. Thanks for the tip, in other videos they don’t mention tank must have no pressure which is an important detail
That's what it's there for Buddy...I still remember my first plug.
Another tip: unloading dusty product (cement) into rail cars with no dust collection. Run lots of top air (no aerators) so you don't stir up the product, keeps the dust to minimum until the very end. You want the top air to push the product and just enough line air to keep it moving.
Give this man a beer or something.
Great tutorial and demonstration, retired bulker here, have had to do this a few times, beats the alternatives. Have done this with a partially filled compartment ,if you're using the most foreward one you may get some product of the vent. I would strap a purge bag over the outlet if the load was pellets.
Great advice...noted. I got out of pneumatics awhile back and was pulling an RGN. Luv at first sight.
Thank you very much!!! I been up all night unloading 3 different trailers and the last one clogged up on me .....thanks to your video its flowing again!!👍👍
I just tried this and it worked. I also wish I had washed 2 hours ago. Thank you sir!
Great video
Yep, back when I hauled pebble lime and guy taught me how to do this. Sure saves a lot of time and wasting of product, not to mention the laborious task of unhooking and dumping those heavy hoses.
I just started bulk tank work and I’ve been killing myself with these hoses. Now I know
Very helpful thank you have a great day be safe.
Anytime...an ole skool Han'd taught me and Im just passin' it on.
This may or may not work for you depending on how much product is left in your tanks. If you plug up 5 seconds into the unload lol and are still full I wouldn’t recommend this. Helps if you’ve got at least on empty pod. Good video driver
Im overly cautious when starting product to prevent a plug with no empty hoppers available. Its always nice to draw back into the rear one which is why that is the first to come off. When I plug on full tanks I suck it back into the first hopper which essentially spreads the return along the product line... However the pressure differential in a loaded hopper is still enough to break a plug. My number one rule is DONT PLUG UP.
If it blocks that quick the loader really needs a slap with a shovel and instructions how to use a sieve and take care of a loading process. Been there, seen the lumps fall into the trailer during loading, locked the cab and walked away :) If they can't load the product at the factory I'm not sweating and struggling trying to discharge at the customer premises (usually the sites with very low air pressure saftey cutoff systems in my experience).
@@glenjones6980 damn loaders need a slap regardless lol most the ones I’ve met
@@strpped379 DONT PLUG UP was always my number one rule as well but we all know how it goes lol
That was a great tutorial👍I wish I had searched for this before id got my first blockage! Would have made life easier lol. Only difference with my setup is the valves are air operated! So they dont open and close quickly.
Some of my worst plugs I had to dig'em out. But when Im at the controls and shut it down quick...this works most everytime. Im out of pneumatics temporarily and back on Floors and Hoppers...the dairy side of business.
So for the last 45 minutes ive being trying to unplug my hose.....i mean my arms are sore drom plunging it.....needless to say the guy comea out and says shut it off.....and im like aw shit....my first time here and i fucked it up....he comes back and says sorry man, one of our maintence guys shut the valve to the silo...😆😆😆😆😆😆😆😆
Aaaaaaaaahhhhhh....that BLOWS.
Man this just helped me out.
A few more details for the layman but a very good video...
Sometimes it doesn't work. So must vacuum hook up
The only times it fails me is when I haul meat meal...greasy lamb. It doesnt fall or blow well. Then...its all about manually cleaning out the connections. Other than that...its 100% reliable.
Thanks for the video. How tippy are those trailers to pull? Seems like they could go over pretty easy in corners. Have a nice weekend.
@69adrummer They dont feel top heavy at all. Most of the loads are very low center of gravity. Limestone, Grit, Rice...all sit very low in the trailer. Some fluffy'er loads will fill the entire trailer but settle as you go down the road...what was full when you left, later settles to 4 or 5ft below the top. Now, on the other hand ...the pull trailer on a set of doubles can get a little squirrelly on you.
One thing I’m having an issue with working with older unmaintained tanks is the aerator cups actually being so full and clogged that air won’t flow proper causing issues to fully unload a hopper. I could use some advice on cleaning them properly if you have any advice
Honestly, nothing beats regularly cleaned aerators. I had to learn to take them apart and put them together when they werent working ideal 400 miles from our yard. Some guys run the aerators while getting washed out but depending on what you haul I try to keep them dry dry dry!!!
@@strpped379 oh I hear ya i gotta keep ‘em dry as well. hauling lime and cement I’d like to learn how to do so but can’t seem to find any advice on how to do it. I had a guy tell me that there’s nothing wrong it just means there’s product in the aerator line. But there’s definitely an issue if I gotta build pressure and try to empty a hopper 3 times before she even sounds empty. There’s nothing worse then not being able to get all the way empty.
@@kyler7024 ooooohhhh, definitely sounds like your hoses to the aerator are restricted. Its pretty easy to clean just loosen the hose clamp with a screwdriver or socket. Next time youre empty look down in your tank and see if old product has caked on the walls. I have 1 vid posted where a guy is inside the pneumatic pressure washing it after a bunch of mold and cake really obstructed the walls. Thatll hang thousands of pounds of product. Cement and Lime shouls have no issues coming out...those are dream loads...chicken meal, lamb meal, fish meal...absolute nightmare loads
I blow 00 sand at 15 all day and rarely clog and when I do I just cut the product off and bang the blow down open and it sucks it up every time but I keep the pressure high
I luv blowing that high...the distance sucks though. Limestone/Grit is so abrasive it eventually wears holes in the hoppers, hoses and elbows. I once cemented my pop off valves on a powder train and blew off 55k at 20lbs in 18minutes....was never brave enough to do that twice. Keep up the good work...blow baby blow
@@strpped379 Yeah it’s so much more efficient and Sheesh that’s high I’m not comfortable over 16 but yeah sands just like a sand blaster it eats through EVERYTHING I don’t deal with powder much but I’ve found low pressure to work a lot better with powder
Would this work for Cement powder trailers?
Absolutely...works best on powders like cement.
Does this work with plastic pellets?
@ breakingbadken I couldnt answer that. Ive never hauled pellets. However, the principle is the same.
Did you try ?
@breakingbadken Have you tried
It sure does. Since pellets will flow a bit, like back down the tube, it works really well
U gotta have at least 1 empty pod right?
Having an empty Hopper helps but not necessary. I've plugged up immediately a few times and it's just the draw put on the product line that is enough to release the plug. If not...I've had to manually open and break down each section and clear them with a long pole or rod. In general, pneumatics are hard to plug...but meat meal SUCKS !!!!!!! Cement, Lime, Fly Ash, Grit, Rice, Sand and Powders...piece of cake
@@strpped379 I've done that too
If you're plugged real bad with a full load ,you might have to climb up on top and crack a hatch cover open, it works every time.
@@normangilbert1236 This worked with 56 sand and no empty hoppers. Thank you
I need to show the idiots at my job this video cause they unhook their hoses and blow product all over the place
Same here, only plastic pellets
