A system and method for feeding a high volume of low-bulk-density and pressure-sensitive feedstocks into a pressurized environment. The system includes a lock hopper filling system, one or more lock hoppers, a feed bin, and a feeder. The methods involve using such a system to feed bulk materials into a pressurized environment by feeding bulk material from a low pressure into the surge bin, filling the one or more lock hoppers from the surge bin, operating the lock hoppers, and discharging lock hoppers into feed bin, and discharging feed bin into the high-pressure zone using feeder.

Provided is a tank container which can accommodate and transport powder formed of hazardous material powder or the like while suppressing the contact of the powder with moisture in the air and an increase in temperature to a temperature equal to or higher than a predetermined temperature, and which can also easily discharge the powder, and a method of manufacturing the tank container. A tank container includes: a tank main body portion formed into an airtight cylindrical shape, which is configured to accommodate powder therein, and which is closed at both ends along a longitudinal direction; a plurality of accommodation and discharge portions, which are arranged so as to be adjacent to each other along the longitudinal direction in a lower portion of the tank main body portion, which have base end portions each airtightly joined to an inner wall of the tank main body and to an adjacent portion, and which have distal end portions each formed into an inverted tapered shape so as to protrude outward respectively from openings formed on an outer peripheral surface of the tank main body portion; a heat insulating portion formed on the outer peripheral surface of the tank main body portion; and a container frame portion having the tank main body portion fixed thereto.

An injection mixer is provided, which includes an injection module, a valve seat module, and an adjusting module. The injection module may be disposed to penetrate one end of a bucket container. The valve seat module may be disposed at the end of the injection module, and the valve seat module may be disposed with at least one fluid supply channel and at least one outlet channel. The adjusting module may be disposed at the valve seat module to penetrate therethrough. The adjusting module may be movably connected to the injection module. When the adjusting module is driven to move the injection module towards or away from the valve seat module, an annular protrusion may approach or move away from the inner wall of the bucket container, and a size of the predetermined gap may be reduced or increased.

A mass-flow hopper that stores solid particulates and provides gas assistance to readily discharge the particulate matter. The mass flow hopper has an upper conical section connected via an intermediate section to a lower conical section having a lower discharge orifice. The lower conical section has a frustoconical configured gas impermeable wall lined with a gas permeable fluidizing plate spaced therefrom to define a lower space. The upper conical section slope is steeper than the lower frusto-conically configured gas permeable wall slope. Gas injected into the lower space passes from the lower space through the gas permeable fluidizing plate into the hopper to form a fluidized layer of gas between the solid particulates in the hopper and the gas permeable fluidizing plate. The fluidized layer of gas reduces wall friction within the lower conical section to facilitate discharging the particulates from the hopper.

Removing sediment from storage tanks without physically entering the tanks. More specifically, embodiments are directed towards inserting fluid into the storage tank via a liquid return line and injecting air into the storage tank via an air injection line to suspend sediment, draining and filtering the sediment, and returning the filtered fluid back into the tank via the liquid return line.

This invention relates to a transportable modular container system for fluid freight. The transportable modular container system comprises a container module including a reservoir configured to hold a fluid; an adjustable support for the container module, removably securable to a load area of a freight carrying transport and reciprocatingly adjustable between proximate and distal positions, the container module being located relatively closer to the load area in the proximate position than in the distal position, and wherein a zone for secondary freight is defined between the container module and the load area when the adjustable support is in the distal position and removably secured to the load area of the freight carrying transport; and a removable fluid flow control module for controlling fluid flow of the fluid between an external reservoir and the container module reservoir and releasably connectable to the container module.

A hopper bottom for supporting a cylindrical side wall of a grain bin includes a hopper wall having an inverted cone shape supported on upright support legs. A manifold duct is supported above the hopper wall to define a manifold passage therein extending circumferentially adjacent to the peripheral edge of the hopper wall. A plurality of outlet openings formed in the manifold duct in communication from the manifold passage to an interior of the hopper wall for open communication with the grain bin thereabove. An inlet opening extending through the hopper wall in alignment with the manifold duct receives ventilation air from a blower to direct the flow through the manifold duct and into the grain bin through the outlet openings of the manifold duct.
