The invention relates to a vibratory floor made up of shaker modules protected against the entry of dust, and capable of emptying cohesive products. The inner volume (10) of each module is connected by means of a pipe (14) to an air or clean gas volume (19). Each module past the first row is provided with an anti-pressure device (46) made up of an anti-pressure plate (47) situated above the motor cover (44), supported by two flanges (48) and (49) resting on stationary parts (36) on either side of the module. The modules thus formed are protected against the entry of dust, and effectively emptying any cohesive product from silos, vessels, railroad cars or any other containers, without human or mechanized intervention.

The invention relates to a seal assembly comprising: a seal for a bulk material container, having a ring-shaped connecting flange with a through opening and a first moving element; and a seal member for selectively sealing or opening the through opening. A container wall of the bulk material container can be attached to the connecting flange. The seal assembly also comprises a docking device having a housing, a second moving element, and a seal actuating device. In order to increase the tightness of the seal, one of the moving elements comprises a peripheral first stripping element, by means of which impurities are stripped from a surface of the connecting flange, in a closing process for sealing the though opening of the connecting flange.

A bulk bag conditioner assembly is disclosed herein. The assembly includes a frame assembly defining a bulk bag conditioning area. The frame assembly includes a first carrier frame with a first ram, and a second carrier frame with a second ram. A first actuator assembly includes a first end fixed to the first carrier frame and a second end fixed to the second carrier frame. A second actuator assembly includes a first end fixed to the first carrier frame and a second end fixed to the second carrier frame. A control unit is configured to simultaneously drive the first ram and the second ram linearly towards each other to engage a bulk bag within the bulk bag conditioning area.

The present invention provides an air blaster 100 for removing jammed materials. The air blaster 100 includes a tank 110 filled with compressed air and a dual piston assembly 400 inside the tank 110 for triggering a blast with minimum energy loss and high impact force. The piston assembly 400 includes an inlet piston 320 connected to an outlet piston 250 with a coupling mechanism such that the inlet piston 320 and the outlet piston 250 move in tandem and pressure acting on the inlet piston 320 and outlet piston 250 pushes the assembly 400 towards top of the tank 110 thereby compressing a dampening device/spring 360. The force produced by the instant discharge of air creates a strong blast of air in the tank 110.

A proppant container facilitates the transportation of wet sand for use in a hydraulic fracturing operation. The proppant container is provided with a system for dislodging the wet sand for subsequent use. This may be done by use of a vibrator or an umbrella valve. In another aspect, the proppant container may be used in combination with a rack having a wash system that slurries the proppant for delivery to a blender tub without necessarily resorting to use of a conveyor belt.

Portable flow aid devices, systems, and methods for promoting bulk powder flow in containers. The portable flow aid devices include a housing having an enclosed internal cavity therein, and at least two vibration motors each adapted to generate vibration and each separately fixedly attached to an interior surface of the housing within the internal cavity to transmit the vibration generated thereby to the housing. Wireless communication with the portable flow aid devices causes the vibration motors to generate the vibrations and thereby apply a localized vibration to portions of a bulk powder within a container and in contact with the housing of the portable flow aid device to promote flow of the bulk powder within the container.
