ABSTRACT:
An improved device for removing and replacing catalyst particles or pellets in an underfloor type catalytic converter is provided. The catalytic converter is a purifier installed in the exhaust pipe of an internal combustion engine for the purpose of purifying the emissions thereof. The catalyst changer includes a canister for containing catalyst particles, a conduit for conducting particles from the converter to the canister and vice versa, an eccentrically mounted vibrator to aid in removing particles from the converter and in replenishing the converter with a fresh supply of particles tightly packed in a catalytic bed, and clamping means for rigidly clamping the changer to the catalytic converter during removal and replacement of the catalytic particles. The clamping means is of a construction and magnitude to cause opposed clamping elements to deform the outer skin or surface of the casing of the coverter. Such clamping arrangement aids in transmitting the full effect of the vibrational forces created by the vibrator to the catalytic bed of the converter, during replacement of the catalytic particles.
