No pics handy, but my home brew parts cleaner, is a 20 gallon barrel sitting in an angle iron frame. I trimmed the lip[ off after I discovered the (Metal, remember those?) oil drain pan woul not seat but with the lip cut off id did.
I cut a small hole in the middle and installed a bathroom sink drain and tail piece, with a screen, (didn't want to be fishing for small fasteners in the glop on the bottom).
A recirculating pump, an old TP oil filter with the restrictosr drilled out, and some soft copper and I thought I was set, except the damn thing splattered solvent everywhere.
Solution: I added a fitting to adapt a std. bath faucet diffuser, onto the outlet, added a T near the bottom of the copper upright and a valve to create back pressure and ran the excess pressure to a "swirl tube" that helps keep the debris in the drain pan/basin clear.
Been using it well over 25 years..
I did later add a curved "back splash" just to help contain the splatter from the stream hitting parts and it helps a lot.
I've since added an old Matag Jet clean dishwasher as an automated parts cleaner. works great the few time I have used it.
