Filter tube holding grommet

A dust filtering and collection system for filtering dust and other debris particles from an incoming dust laden air stream, such air stream generally being used for conveying granular material into or from a bulk tank trailer, a railroad car, or other conveying vehicle, the filtering system designed to be functioned by vacuum air pressure, operatively generated by a blower, to draw in the soiled air into the filter system, to cleanse such air for further use in the conveying of the granular material. The air flow may be reversed, to provide for a dislodging of any dust particles from the filtering system, and to cleanse the filter for further efficient usage of the system in conveying granular material into or out of the tank trailer, or other vehicle during usage. The filter system includes a pod of filter tubes encapsulated by a polymer header that mounts to a transverse plate that secures to the approximate upper end of the filter canister of the filtration system.

Vacuum filter assembly for cleansing air for use in transfer of bulk, granular material as in conveying vehicles

A pressure and heat molded polymer tube, formed of miniscule polyethylene beads, each in the vicinity of 115 um powder in diameter, which when compression molded forms pores that are of uniform diameter throughout their length within the range of 5 um-10 um, the tube having an upper flange, that mates within a correspondently shaped grommet, which when applied to the transverse plate of an air filtration housing, functions to cleanse highly efficiently the dust particles and debris from the air being filtered, when passing through the filtration system, so that such purified air can be discharged safely.

A sealed manhole clamp securing a manhole cover to a weld ring, including a lever assembly, the lever assembly having a lever arm and a cam, a pivot bolt, the pivot bolt having a cylindrical upper portion, and a lower portion, the lower bolt portion threadedly engages upwardly within the cylindrical upper portion of the pivot bolt, the cylindrical upper portion being pivotally pinned to the lever arm, the lower bolt portion being pivotally mounted to a seal ring, wherein since the lower bolt portion threadedly engages within the cylindrical upper portion, the entrance of any debris, dust, or moisture is prevented from entering the region of this threaded engagement of the pivot bolt components.

An alternative bottom drop and straight tee discharge from bulk tank conveying granular material, the tee having extensions for the automatic and manual operations of a disc valve, pivotally located within the horizontal section of the tee, during functioning. The disc valve may be manually operated, or pivoted through motorized operations, to allow for the alternative flow of bulk material from the vehicle hopper. The disc valve has an annular disc, integrally formed with upright supports, that are bearing mounted by shafts to the sidewalls of the structured tee.
