ABSTRACT:
A substance delivery and filter system for use in delivering or conveying a dry, fluid powder substance from a closed container to an open receptacle is provided. The delivery and filter system includes a filter housing having a heavy particle cyclone separator, a fine particle filter bag assembly, a substance inlet port positioned just above the heavy particle cyclone separator, a substance outlet port positioned at the bottom of the cyclone separator, and a filtered air outlet port communicating between the clean side of the filter bag assembly and the outside environment. The powder substance in the container is entrained in an air stream and introduced into the filter housing through a conduit connected to the substance inlet port. The heavier substance particles fall downwardly from the swirling air stream caused by the cyclone separator and are discharged into an open-air receptacle from the substance outlet port. The air and particulate matter are forced upwardly to the filter bag assembly where the fine particles are trapped on the outside of the filter bags. Filtered air is exhausted from the filter housing through the filtered air outlet ports. The filter bags are cleaned by bursts of air introduced into the filter housing through the filtered air outlet port to purge the filter bags of any substance collected thereon.
