Multiple airlocks on one transfer pipe?7/21
I'm assuming this works, just playing with an idea. Can you have multiple airlock s dumping into a common pipe for transferring?
We currently have a 20hp Murphy Rodgers baghouse, and a separate 7½hp Oneida on the router. I'm thinking about getting rid of the baghouse, and moving the cyclone into a lean-to on the side of the shop, along with three more of those dust collectors. Line them all up, airlock into a common pipe, blow it into a trailer.
We're a very small shop, in a good sized building. We have a lot of equipment for the number of workers. It's tough to justify the bigger dust collector running when it's just a dude standing at a cut off saw, and nobody else needs DC are that time. I've got three trunks that come together and would be super easy to modify them so they go out the wall separately. The pipes could easily go out between studs, the current opening in the wall for dirty air going out, and clean air coming back would be more than adequate for just a return air from the lean-to
I priced out a new system, I don't have $100k to throw at this problem, and it wouldn't cure the electrical draw problem.
No airlocks here but would imagine Oneida would give you valid answers with only a modest sales repercussion.
Your trajectory sounds exactly like how Ive tried to setup my shop with modular capacity that can be ramped up or idled as demand occurs. To me at least the "old world" philosophy of building a monster plant works as long as your confident in continuous demand, little to no variation in the type of production, and so on. When we have a nice batch of good paying CNC work, its very nice to have that machine, its DC, and its light bank, energized. The shop is quieter, cooler, and the electric and heat bill (winter) is a lot nicer.
Likely not true for the big boys but it sure does help when you have peaks and valleys and periods where your making product thats not the anticipated norm. It allows you to get a bit more competitive in many aspects as well because your operating costs are a bit more dynamic.
The only issue I see is that you need to size the exhaust pipe and blower for the trailer to keep up with maximum usage, ie. Everything running at max capacity. Not sure if you could then add a VFD to that blower to ramp it down to lesser usage and keep material flowing thru the pipes and not lose velocity and settle out before the trailer. Interesting idea.
