Can anyone explain what’s happening here?

"Filter cake" is the built up material on a filter after a fluid removed. This machine sequentially separates filters so the filter cake can fall off. Depending on what you're doing, filter cake can either be wanted or unwanted material.

I can only assume the machine is putting them all back after the unpacking, since there's nothing falling out

or it starts at the back and its 50 plates from the first one.

What kind of fluids would you run through a filter like this?


Fun_Wind7710

I'm a layperson, but it sounds like they're typically used in mining industries. I would guess that maybe a slurry of pulverized ore and a solvent that selectively dissolves the desires metals. That would leave you with filter cake that is mostly unwanted rock minerals.

They’re also used in the Wastewater industry to remove ‘wasted sludge’ as part of the dewatering process. Think of a Wastewater treatment plant as a giant aquarium filter. Sludge is literally the beneficial bacteria that you wash out of your aquarium filter. It’s expensive to cart off water, so they use these filter pressures to remove the water. Then they can truck off the dry wasted sludge.

A lot. Everything from wine, beer, and Apple cider to mineral concentrates at mines to thickener tank sludge.

We use filters presses at my job similar to this and they are for removing activated carbon from our products

I work at a pharmaceutical company that processes amino acids after a dissolution process which turns crude crystal into a liquid we add things like EDTA, Sodium metabisulfite, and Activated Carbon to remove impurities. This mixture is then ran through a filter press which removes the carbon which has binded to any impurities in the dissolution. Hope this helps

Thank you for the explanation


twhiz

Also curious!

I found this [video](https://youtu.be/P3AUlCF2Fv4), but now I’m even more confused/interested.

As u/Fun_Wind7710 points out, this machine separates sequential layers of a filter so that the solids caught in the filter (filter cake) can fall out, which is unfortunately not very visible in OP’s video. Disclaimer: my education is in chemistry, not mining, so take the below with a… grain of salt (sorry) This is a common separation technique in mining; rock is mostly a bunch of metals and metal salts mixed up together. When we want to separate out part of a rock, it’s often easiest to grind it up and mix it with water to make a slurry. Then by adding acids, bases, or other metal salts, we can selectively dissolve parts of the rock. If we then filter the slurry, we’ve effectively separated the soluble parts from the insoluble, refining the material of interest. When the filters are clogged up by the solid from the slurry, the process in the videos allows the solid filter cake to be removed by agitation or just gravity

Thanks for clearing that up


seniledude

Thank you. Have my free award for the day


JamesthePuppy

Why thank you!

The thing slides left until the right arm is in place. Then it slides right and the left arm pops up, and it moves the other thing to the right. Then the things slides left again, and it repeats.


about6bobcats

I used the same kind of filter when I brewed beer. We used it to filter our lagers.


rgolden4

Same


Arandomfan27

Where cake? 😔


furaisuwatto

It was a lie


Mister_Krunch

This was a triumph!


MECHAC0SBY

The whole machine is actually one of those elaborate cakes you think is a real machine


ChiefyPoof

I was told there would be cake.


GroceryScanner

The cake is a lie


TwoSillyStrings

#SPAAAAAACE!!

Pushers lift and lower automatically because of their geometry, engaging just the plate that needs to be moved. Trolley just needs to move back and forth, stopping upon resistance to movement.


The_Best_Dakota

It’s so satisfying

My familiarity with filter presses is via sugarmaking (i.e. making maple syrup). Which had me wondering exactly how much maple syrup is being made at that facility. But then thought, ah, must be Quebec. And then someone mentioned mining.


the1theycallfish

These things are wild to operate.


mashedmattatoes

Okay... cakes aside... Is that claw painted to look like a corgi?


cap-slow

It looks like a robotic dog to me


TypicalGamer88

I thought it was a real dog just chilling on the machine.


Hawt_Dawg_II

Shit mane that used to be my nickname in college!


Tiny_Artificer

Good crab


Ermahgerd_Rerdert

Lies! I see no cake!?


billoftt

The door storage and retrieval system from Monsters Inc.?


peanutbuttet93

I was promised cake?


EstebanLB01

I don't see any cake there man, you lied to me
