The auto weigh automatic tank filling system provides an automatic system for filling a tank of a dry bulk tank trailer with bulk material that is properly distributed through the length of the tank interior volume and is at a weight limit for safe and legal operation of the dry bulk tank trailer.
An automated bulk tank pressure exhaust valve automatically exhaust air pressure from a bulk tank of a bulk tank trailer in response to a sensor operatively communicating with the exhaust valve sensing an absence of air pressure or air flow in a tank pipe communicating with the bulk tank. The sensor is also operatively communicated with in alarm that is activated in response to the sensor sensing air pressure or air flow in the tank pipe or a truck coupled to the bulk tank trailer.

VACUUM FILTRATION SYSTEM FOR A DRY BULK TRAILER AND METHOD OF USING THE SAME
A filtration system for a dry bulk trailer tank includes a canister containing a filter media separating a dusty air inlet and a clean air outlet on the canister. A dusty air line connects the tank with the dusty air inlet. A clean air line connects the clean air outlet with the exterior environment atmosphere. In a loading mode material is pneumatically conveyed from the tank through the dusty air line into the canister, through the filter media and from the canister through the clean air outlet and the clean air line. In a cleaning mode air flow is reversed and flows from the exterior environment atmosphere through the clean air line and the clean air outlet into the canister, through the filter media dislodging material from the filter media, and from the canister with dislodged material through the dusty air inlet and dusty air line to the tank.

Pressure relief valve for a blow-down pipe to prevent the entrance of animals and insects from entering the piping system of a bulk tank delivery trailer
A directional hopper tee has a fluted interior vertical pipe that merges into a horizontal pipe. The vertical pipe has an opening that connects to a hopper to receive bulk material, or product, and a horizontal pipe centered upon the end of the vertical pipe. The horizontal pipe has an inlet that also receives bulk material and pressurized air from ahead of the hopper and an opposite outlet that discharges the bulk material from the hopper tee. The vertical pipe has a flange that abuts the hopper and an opening in the flange that matches the opening of a valve on the hopper itself. At the opening, the vertical pipe begins to turn towards the outlet of the lower pipe with an internal flute. The flute begins immediately at the flange resulting in a vertical pipe with a curved shape towards the outlet and a square shape towards the inlet. The present invention raises the ground clearance of the horizontal pipe by at least an inch resulting in a hopper tee that clears at least 7 inches above the ground. The hopper tee of the invention also unloads at least 15% more product per minute at temperatures closer to product temperature. Alternate embodiments of the present invention provide a reinforced flange, a drop tee, and a low profile drop tee. The present invention aids in the unloading of bulk materials from various haulers.
A mounting assembly uses one hinge and one cam bolt mutually offset upon a two piece collar. A hopper tee has a member usually a vertical pipe and occasionally a horizontal pipe that connects to a hopper flange to receive bulk material. This assembly has two collars that mutually engage and surround a hopper flange. Pins pass through the collar pieces and the hopper flange then secure to tapped holes in the collar pieces to prevent rotation. A collar piece mounts a hook bolt and the other collar piece mounts a hinge in a spaced apart and offset manner. The other collar piece has a pivotal connection to a hinge arm and opposite the hinge arm, the hook bolt engages a cam. Opening the cam unfolds the tee downwardly while the hook bolt remains engaged. This partially open position allows for removal and installation of a valve. In opening and closing the assembly, the hinge arm spaces the flange below a hopper to admit a valve. The present invention fits standard hopper tee flanges, has a ground clearance below the horizontal member of at least 7 inches, and aids in the unloading of bulk materials.
A pneumatic aerator aids in bulk material unloading, handling and transport using tank trailers, hopper cars, and other containers, as its aerator introduces a cyclonic air flow and vibration into the bulk material. This aerator has a housing, one or three guide tubes, an aerator extending through the housing, a gasket upon one end of the aerator generally within the container of the bulk material, and an optional wearplate beneath the gasket. The aerator has a stem with one vane, preferably three vanes, where the vanes and contiguous fins curve counterclockwise in a helical manner. The airflow past the fins and vanes acquires a counterclockwise rotation, rotating the air as it exits radially from the gasket increasing the bulk material unloaded per hour. This aerator also has various gasket thicknesses and edge conditions, guide tubes, and various shapes in the vanes and fins for alternate speeds and directions of airflow. This aerator increases the rate of unloading of bulk materials from tank trailers, hopper cars, and various containers and transporters.
