Title: Joseph A Parenti: Innovator in Coal Mine Air Cleaning Technologies
Introduction
Joseph A Parenti is a notable inventor based in Morgantown, WV (US). He has made significant contributions to the field of air cleaning technologies specifically designed for coal mining. With a total of 2 patents, his innovations focus on improving air quality and safety in mining environments.
Latest Patents
One of his latest patents is an "Apparatus for cleaning air in coal mines." This apparatus features a large-capacity main blower that draws air from the coal face. The air is filtered through a grid that deflects large coal pieces into a refuse bin. The main stage of centrifugal filters separates dust and particles, discharging clean air back into the mine. The dirty air is further processed through a secondary stage of filters, ensuring that only clean air is released into the atmosphere. An air balancing device is included to maintain proper operating pressures, enhancing the efficiency of the system.
Another significant patent is the "Blower and dust collecting machine and method of operation." This invention utilizes a blower with an exhaust fan that draws dust-laden air from the coal face. The air passes through a series of individual centrifuges that concentrate the dust, which is then discharged into a collection chamber. A grid prevents large particles from entering the centrifuges, while a second stage of centrifuges removes finer dust particles. The cleaned air is then combined with dust-free air and returned to the mine.
