Transfer systems for receiving and conveying material such as earthen slurries discharged from vacuum excavators are disclosed. The transfer system may include a holding tank and a conveyor such as a drag-slat conveyor that extends into the tank to remove and convey material from the tank. The transfer system includes a hatch. The hatch is moveable from a closed position in which vehicles travel over the hatch to an open position in which the holding tank is open to receive material from the vacuum excavator.

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 a 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.

In accordance with presently disclosed embodiments, a stackable bulk material storage container is provided. The bulk material storage container includes a frame having a top portion and a bottom portion, which is supported by a plurality of rigid bars. A semi-rigid containment structure is further provided, which is supported by the frame. The semi-rigid containment structure may be formed of a plurality of interconnected or attached panels of thin steel sheets, carbon graphite or fiber reinforced plastic. Alternatively, the semi-rigid containment structure may be integrally formed of a roto-molded plastic material. The frame optionally has an opening at the top, which is sized to allow for easy removal and replacement of the semi-rigid containment structure.

Controlling the dust emissions from the discharge of bulk materials from a container provides many benefits. A container engages a support structure that includes a frame. The frame includes a dust control enclosure coupled to an outlet or a hopper at the top of the frame and the container or a discharge gate of the container. The dust control enclosure comprises a collapsible and flexible material so that a tight seal is formed between the container and the hopper or the outlet of the frame. Dust from the discharged of the bulk material from the container is contained within the support structure. A dust control panel may also be disposed at the top of the frame to prevent any dust from migrating through the frame. The container may comprise a plurality of dust enclosure panels to further prevent the escape of dust during discharge of the bulk material.

A fixing clamp (2) for discharge outlet of intermediate bulk containers is disclosed. The discharge outlet (1) comprises a flange edge (3), a discharge connecting port (5) and a discharge outlet clamping part (4). The discharge outlet clamping part (4) is a polygonal structure. The fixing clamp (2) comprises a fixing clamp body, a clamping portion (8), elastic guiding ribs (7) and anti-release portion (9). A passage for accommodating the discharge outlet clamping part (4) is formed in the middle part of the fixing clamp body. The clamping portion (8) is used for clamping the side surface of the discharge outlet clamping part (4) when the fixing clamp (2) and the discharge outlet (1) have been assembled. The elastic guiding ribs (7) will be squeezed by the side surface of the discharge outlet clamping part (4) to deform When the leading-in surfaces of the elastic guiding ribs (7) contact with the side surface of the discharge outlet clamping part (4). The elastic guiding ribs (7) restore elastically and the anti-release portion (9) are engaged with the side surface of the discharge outlet clamping part (4) to prevent the fixing clamp (2) from being separated front the discharge outlet (1) after the fixing clamp (2) and the discharge outlet (1) have been assembled. The fixing clamp (2) can be transversely pushed in to be assembled with the discharge outlet (1). The fixing clamp has low requirements for assembly accuracy, and is favorable for saving cost and increasing efficiency.
