Embodiments of methods and systems of transferring proppant for fracking to reduce risk of production and release of silica dust at a well site are provided. An embodiment of a method can include positioning a plurality of containers each having proppant for fracking contained therein onto a conveyor at a well site, downwardly discharging proppant from each respective container of the plurality of containers, funneling proppant from the one or more outlets of each of the plurality of containers through a plurality of conveyor hoppers, receiving proppant onto the conveyor belt, conveying proppant on the conveyor to a chute, and depositing the proppant into the chute for use in a blender or other location at the well site.

A system includes a frame with a back rail and a ground rail. The back rail and the ground rail are positioned transverse to each other. A guide is attached to the ground rail. A sliding tilt loader apparatus includes a bucket; a chute; and a first pivot mechanism attached to a first end of a rear portion of the bucket. The first pivot mechanism is to translate along the guide. A second pivot mechanism is attached to a second end of the rear portion of the bucket. Rotation of the first pivot mechanism and the second pivot mechanism coincide with tilting of the chute and the bucket causing the chute to angularly rotate and align with the bucket upon the chute and bucket reaching a completed tilt position.

A bulk material container can include a body, having a plurality of side walls, a bottom, a cavity, and an opening, and a first engagement element. The plurality of side walls are coupled to the bottom, and the cavity, which is configured to receive a bulk material, is formed within the plurality of side walls and above the bottom. The opening is formed by the plurality of side walls spatially opposite of the bottom and is configured to discharge the bulk material when the container is at least partially inverted. The first engagement element can be configured to receive one or more prongs of a transportation device or a bulk material unloading device. In some embodiments, the container may also include a second engagement element and/or a third engagement element, for example with the first, second, and/or third engagement elements differing from each other.

A container for the transport and storage of liquids comprises at least one upwardly open socket at the top of an inner container. A clamping disk has an internal thread that can be screwed onto an external thread of the socket, thereby clamping a container top at the edge of its opening. A screw lock interacts with the external thread of the socket and the internal thread of the clamping disk and prevents unintentional loosening of the clamping disk and the socket.

A charging port 5 in an upper part is covered in an openable and closeable manner with a lid body 6 of a sliding door type (sliding type) that reciprocates horizontally. The lid body 6 reciprocates in conjunction with a movement of an operation member 50 provided in a side part of a container vessel 3 or at a location close to the side part. It is preferable that the charging port 5 includes an opening that is long along a length direction of the container vessel 3, and the lid body 6 reciprocates horizontally in a width direction of the container vessel 3 to open and close the charging port 5.

A coal blockage-proof feeding pipe apparatus for a coal storage Eurosilo includes a central telescopic feeding pipe, a coal blockage-proof feeding pipe, and a feeding pipe mounting base connected. A middle part of a first section of round pipes of the central telescopic feeding pipe is of a conical pipe structure with a smaller upper part and a larger lower part; the first section of round pipes is connected to an upper end of the coal blockage-proof feeding pipe; a dust return plate is arranged inside the coal blockage-proof feeding pipe to guide dust-laden gas, generated at a coal falling point below and ascending along a pipe wall, downward, preventing the dust-laden gas from ascending along a cylinder wall into gaps among round pipe walls of the central 10 telescopic feeding pipe. The coal blockage-proof feeding pipe has an exhaust port to discharge the internal dust-laden gas to the outside.
