Taking apart this machine piece by piece

They also have a gauge on the scrubber and I am trying to find out why that is so.

 

[4metals]

I don't see any gauges on the picture of the fume scrubber, there is a sight glass which has a face that could look like the face of a gauge. The sight glass is like a port hole which allows you to see the liquid flowing over the packing.

Hi 4metals
I think there is a gauge on the machine

 

[4metals]

The only things you measure on a scrubber are the flow from the pump, so a pressure gauge may be on the plumbing line, and the other thing you measure is the airflow through the scrubber using a velometer. This is measured at the hood opening.

Some manufacturers put in an instrument to measure the pressure drop across the packing, this is expensive and they usually give you a hard time because they clog up. Straight caustic scrubbers are just backwashed periodically to maintain the airflow.

I don't believe any of these are on this scrubber but I can be wrong.

Hi 4metals
Those meters must be for what you are talking about
If you look on page 1 of the pdf file pasted by HAuCl4
there you have the refining unit with the tumble than the scrubber and what is that machine on the right hand side of the picture.
I am trying to figure that one out but I don't have a clue as to what it might be

Steve,

I think that is the scrubber for the reactor. The circulating pump is on the bottom front, sight glass top front and thier blower on the top of the unit with the exhaust.

That PDF does show a pressure gauge in the liquid feed line. The unit to the right is what they call a cementation tank and it is where they precipitate the gold. They precipitate with SO2 in the tank, they do not cement with copper as we speak of here on the forum.

They filter the solution through a PVC filter that rolls around on the floor and in the picture it is parked under the tumbler hood. It draws a vacuum with a double diaphragm pump and pumps the liquid to the next process. After they drop the gold they move the filter under the stand on their cementation tank and filter out the waste from the fine gold.

FWIW if I were to copy or reverse engineer a machine (or part of it, like a scrubber). I'd pick the italian ones, from the website posted by 4metals. Forget about the other 2 videos. Paying retail for it, well not for me, but maybe for others.

 

[golddie]

If I was to design a system like that Italian unit,I would make the cementation tank in the same workplace as where the reaction vessel would be.
All in one place so that you dont have to remove a vessel that has AR or something else and deal with the smell.

 

[golddie]

If you go down to page 7 I think there is a system where you have the reaction vessel and the cementation tank in the same area.
I dont know why they didnt do the same on design on page 1

 

[4metals]

That system is a static system because the reaction vessel does not tumble, the static systems require silver to be lower to work effectively, the tumbler plants seem to grind away chlorides and effect a more complete reaction.

The tumbler plants process larger lots but since the liquids are pumped from one closed container to the next the fumes shouldn't be too bad. Except of course for the most discriminating noses!

Hi 4metals
There are so many interesting systems on this pdf file.
I am on page 18 and I read the info quickly but I didn't exactly understand what that unit was for, maybe if I read it more carefully it would make sense

Hi 4metals
It looks like I was interested in refining machines for a while and I had asked about this unit

[4metals]

I remember that post, just re-read it and the pieces are what I thought they were. Only difference is now I've seen one standing in front of me and I was impressed with the craftsmanship.

But you can still do it in buckets.

I have built this system of mine and its working very well.
Thanks to my friends here in the forum
Virtual friends to be exact.
If I was to make another one it would be flawless
Right now I see mistakes on it and I should not have made those mistakes and I cant fix them

For example I placed my blowers on the right hand side of the room when I could have placed them one them left hand side
and this way I would have less curves.

I also learned a lot about installing ventilation systems
I know I need more experience
I said maybe I can try to find customers that need to have things like this built.
Thanks again

Have any pictures? I'd like to see pictures of peoples fume hoods and closed systems to get an idea of what I will do once I get room to build one. Come on guys. Heres your chance to show off your creations

Hi goldenchild
Till now we have not seen any pictures of a system and I think it can be helpful for future projects.
I will take a few pictures and post them for everyone here.

None of your fumes are being scrubbed!

You connect to the top of your tank with a tee. The fumes will flow straight past the tank to the blower and not enter the tank at all.

Scrap all your plumbing and rebuild like this. You only need (3) 6" elbows and some pipe.
