Abstract:
A bulk material storage container assembly for storing and unloading particulate material includes a storage vessel adapted to hold particulate material. A discharge port is in fluid communication with the storage vessel and with a discharge port outlet. The discharge port is also sized and shaped to facilitate bridging of particulate material. A shaft is mounted within the storage vessel adjacent to the discharge port and adapted for reciprocal movement with respect to the discharge port. A rake is mounted on said shaft and adapted to disaggregate particulate material that has bridged proximate the discharge port as the shaft is reciprocated with respect to the discharge port.
Abstract:
A paint circulation system includes: a main line; a branch line; a supply pump; and a pressurization device for storing pressure of the paint in a high-pressure state in which the pressure of the paint is higher than a predetermined pressure, and for applying pressure to the paint inside of the branch line in a low-pressure state in which the pressure of the paint is lower than the predetermined pressure, in which sedimentation of the paint is prevented by driving the supply pump so that the high-pressure state and the low-pressure state occur, to cause flow sending the paint inside of the branch line from a side of the painting device to a side of the main line using a pressure difference between the predetermined pressure in the low-pressure state and the pressure of the paint.
Abstract:
An aeration apparatus to ease the emptying of a mass of powdered material from any kind of container. The apparatus comprises a vibrating membrane coupled to a device for pulling and fastening it to the container wall, so that said membrane adheres to the inner surface of the container wall. The apparatus is characterized in that the inner surface of membrane has a number of grooves shaped as radial recesses formed only on the lower half of the inner surface of the membrane itself. Each radial section of any radial recess is advantageously venturi-shaped.

Abstract:
Methods, systems, and device are provided for utilizing a sliding wall hopper. A sliding wall hopper may include one or more sliding walls that may slide with respect to one or more outer supports of the hopper. The one or more sliding walls may make contact with at least a portion of the material moving through the hopper. The material may be discharged to at least a hopper discharge or a conveyor device. Some embodiments may be configured for use with biomass as the material, but other materials may also be utilized.
Abstract:
Methods, systems, and apparatus for mass flow are provided. The apparatus can include a housing, an inlet disposed at a first end of the housing, and an outlet disposed at a second end of the housing. The housing can include a first section and a second section. The second section can have at least one tapered sidewall that slopes away from an inner surface of the first section toward the outlet. The apparatus can also include a divider disposed at least partially within the first and second sections of the housing. The divider can have at least one tapered surface disposed proximate the at least one tapered sidewall of the second section. An edge of the divider can be located between the outlet and a point within the second section where the cross-sectional area of the second section is about three times or less a cross-sectional area of the outlet.
Abstract:
In the device, according to the invention, the retention tank (7) constitutes a distributing chamber which is connected to the external retention tank (10) being a segment of a gravity-flow channel (11) with its cross-section greater than the cross-section of gravity waste water transfer required in the calculations, located on the line of waste water inflow to the retention tank (7), whereas the capacity of the retention tank (7) is at least two times smaller than the capacity of the external retention tank (10) constituting a segment of the gravity-flow channel (11) with its cross-section greater than the required cross-section of the gravity-flow channel (11) for gravity waste water transfer required in the calculations.
Abstract:
A sandbag filling apparatus has an auger within a steel pipe mounted to a wheeled frame for easy positioning. The pipe has a sand receiving end positionable beneath a sand pile, and an elevated end with a sand chute for filling sandbags. The auger flights are substantially spaced from the pipe ID and driven by a motor mounted to the pipe. The pipe has an opening which, when positioned beneath a sandpile, allows sand to enter the pipe and to be delivered by the auger to the sand chute. A vibrator is mounted to the pipe between the opening and the elevated end which vibrates a pair of fins arranged on either side of the opening so that sand cannot form a bridge across the opening. Smaller openings may be positioned beneath the fins on either side of the primary sand opening to ease starting the auger with sand present.
