ABSTRACT:
The apparatus is for crushing used automotive oil filters, and for squeezing out and collecting the dirty oil. The used filter is placed on the platen of a piston, which is actuated directly by pneumatic pressure. The piston has an area of 400 sq cm, giving a crush force of 3 to 4 tonnes. There are no other moving parts associated with the movement of the piston. The piston platen is set in a chamber with a window for receiving the filter, and a door closes off the chamber during crushing. A pneumatic trip valve is actuated by the act of closing the door, to pressurize the piston. The piston is guided in bearings, comprising strips of anti-friction material set in the cylinder walls, which rub on the same surface as the pneumatic seal. The piston is very heavy and returns under its own weight when pressure is released. The seal/bearing surface of the piston is well lubricated by being splashed with oil from the crushed filter. Grooves in the platen direct jetting oil away from the door.
