The present disclosure provides a valve for controlling the flow of abrasive particles along a predetermined path from the outlet of a hopper to a conveying line in a particle collection or transportation system. The design of the valve reduces the occurrence of erosive wear resulting from contact with the flow of abrasive particles. A method of making the valve that enhances the hardness of localized areas in the valve that are subject to high wear conditions is also disclosed.

The present invention relates to a bulk bin for use with a liner bag. The bulk bin includes a sub-structure that is configured to receive forktines of lifting machinery for moving the bulk bin and a collapsible upper assembly that can support a bag with an entrance thereof in an upwardly facing orientation for filling. The bulk bin also includes at least one self supporting stiffened lid, and suitably a pair of lids. The lids may be pivoted from a closed position to an open position by orienting the bin into an inclined position in which the lids can open under gravity.

The present invention relates to a mixing device, comprising a vessel for receiving material for mixing, which can be rotated abut a vessel axis and has a discharge opening disposed in the base thereof, a mixing tool disposed in the interior of the vessel, and a closure lid for closing the discharge opening, where the vessel base and/or the closure lid are provided with a wear-resistant lining on the side facing the interior of the vessel. In order to provide a mixing device having a wear-resistant lining which is less prone to wear, and in the event of wear can be replaced more easily and above all more cost-effectively, according to the invention the wear-resistant lining consists of a main lining part and a wear element, wherein the wear element is disposed closer to the vessel axis than the main lining part.

An improvement to a collapsible liquid holding tank includes a chute which extends outwardly from an opening in one of the tank side walls. The chute is formed by a bottom panel and side walls of collapsible material, the bottom panel perimeter being reinforced by a hinged frame which swings between “vertical” and “horizontal” conditions in which the opening is “closed” and “opened,” respectively. A clamp hinged on the top rail of the tank secures the chute in the “closed” condition in which the bottom panel of the chute extends across the opening. To drain the tank, the clamp is rotated clear of the frame and the chute is swung to the “opened” condition by the weight of the liquid in the tank.

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 bulk material handling system comprising an enclosure, a door frame, and an access door. The door frame is secured to a wall of the enclosure adjacent an access opening. The exterior surface of the door frame is devoid of horizontal surface portions when the enclosure is oriented with the wall of the enclosure in a vertical position. The access door is releasably secured to the door frame and is movable between a closed position and an open position. The exterior surface of the door is devoid of horizontal surface portions when the access door is in the closed position and the enclosure is oriented with the wall of the enclosure in the vertical position.

A swing-away hopper tee assembly comprises a mounting frame, tee assembly, and a valve assembly. The hopper tee assembly is removably mountable to a flange at the discharge end of a hopper. The mounting frame includes a bottom wall, a top wall spaced from the bottom wall, and an outer wall extending between the top and bottom walls to define a channel sized and shaped to receive the hopper flange. The flange includes at least one opening, and a corresponding opening is formed in the channel. A fastener extends through the aligned flange and channel openings to removably secure the mounting frame to the hopper.
