摘要:
An apparatus for sealing a vacuum tank door. The apparatus comprises a circular flange attached to a door panel of a vacuum tank, a horizontal crossbar connected to the center of the door panel and a lifting assembly. The lifting assembly comprises an upper linkage arm, a lower linkage arm, and a hydraulic cylinder. Activation of the hydraulic cylinder causes the linkage assembly to move downwards pulling on the horizontal crossbar and pulling the vacuum tank door towards the tank. Activation of the hydraulic cylinder also causes a connection point of the lower linkage arm and the upper linkage arm to move over-center of the connection between the lower linkage arm to the to the tank creating a tight seal between the vacuum tank door and the tank.

An intermodal container for transporting frac proppant, such as frac sand, and/or other types of granular material is disclosed. The intermodal container is designed to receive frac sand from a quarry or other frac sand supply source. Once the container is filled with material, the container is loaded onto a transportation device and transported to a well site. Once received at the well site, the containers can be stacked and the frac sand stored until needed. Once the frac sand is needed, the containers are placed on a base unit and the container discharges its contents onto a conveying system formed as part of the base unit. The conveying system directs the frac sand to a blending location. The empty intermodal containers can be removed from the base unit and loaded onto a transportation device to be refilled at a mine site.

A proppant discharge system has a container with an outlet formed at a bottom thereof and a gate slidably affixed at the outlet so as to be movable between a first position covering the outlet to second position opening the outlet, and a support structure having an actuator thereon. The container is removably positioned on the top surface of the support structure. The actuator is engageable with gate so as to move the gate from the first position to the second position. A conveyor underlies the container so as to receive proppant as discharged from the container through the outlet. The container is a ten foot ISO container.

A manway gate assembly couples to a tank and provides a liquid tight seal. The manway gate assembly includes a gate selectively slideable in a first linear direction between an open position, a closed position, and/or an intermediate position between the open position and the closed position. The manway gate assembly includes one or more locking members arranged adjacent to the gate and moveable between a locked position and an un-locked position. When in the locked position, the one or more locking members apply a biasing force to the gate in a second linear direction perpendicular to the first linear direction to seal the gate to the tank and provide a liquid tight seal.

In a multi-silo distribution and storage system, the regions between the stationary and transport batchers, and between transport batcher and storage bin are isolated during asphalt discharge with a bellows automatically deployed when clamshell gates of the stationary and transport batchers are opened. The storage bin is provided with a sealing door that lifts vertically for unsealing and slides horizontally to permit access to the bin interior for receiving asphalt discharged from the transport batcher. After registry above the top bin opening, the sealing door is forced downwardly to create a tight seal. For prolonged storage, a fluid seal isolates the lower discharge gate of the storage bin. Steam is delivered to the stored asphalt and bin interior to displace atmospheric oxygen vented through a valve in the bin top. An oxygen sensor linked to a process controller monitors the oxygen level within the storage bin.

A cargo container is modified to carry a fracing proppant such as sand from a quarry or source to the frac site. Openings are cut in the top and bottom of a cargo container and hydraulically operated sliding doors are placed there under. A hopper module with the walls being inclined to approximately the angle of repose for the proppant is installed inside the cargo container. The hopper module is sealed inside the cargo container so that a proppant enters through the top opening at the quarry and flows out through the bottom opening at the fracing site.

A cementious washout container includes a container body having a container reservoir. A hinged chute assembly is rotatably coupled with an upper portion of the container body. The hinged chute assembly includes a chute panel, and a hopper screen coupled with the chute panel. The hopper screen includes perforations overlying the container body. A container drain is positioned at a lower end of the container body, and a container valve is movably coupled over the container drain. The cementious washout container retains and stores washout water and fine particles from multiple loads of cement or concrete and consolidates the washout water and fine particles for a single delivery of the same without requiring multiple separate deliveries of these wastes in multiple trucks.
摘要:
A closure apparatus (1) for covering an opening (2) in a storage tank comprising: (a) a connector to connect the apparatus to the silo in the proximity of the opening (2); (b) a cover (10) to cover the opening (2), said cover having a projection (11) forming a leading edge of the cover (10), (c) an elongate guide member having a guide surface (13a, 14a), the cover (10) being slidingly engaged with the guide member and movable along the guide surface (13a, 14a) from a first position adjacent the opening (2) to a second position covering the opening (2); and (d) an actuator (4,5) to move the cover between the first position and the second position; wherein the projection (11) removes debris on the guide surface (13a, 14a) during movement between the first position and the second position.
