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.

The present document discloses a meter housing for feeding granular or powdered material. The meter housing comprises a meter space with a material inlet and a material outlet, and a wall portion extending between the material inlet and the material outlet. The wall portion has substantially the form of a cylinder sector. The wall portion has a scraper part, which extends substantially parallel to a central axis of the cylinder sector.

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.

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.

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.
