The application relates to an emptying device for emptying a container containing a product, including: a docking portion for docking to a rigid container to be emptied, in particular a drum, wherein in the docking portion a passage is formed by an adjustable sealing device, wherein the passage can be adjusted via the sealing device in such a way that an adapter piece being fixed to a flexible container enclosing the product, in particular a liner or a film bag, inside the rigid container, can be fastened within the passage in such a way that an enclosed inner space defined by the docking portion and the rigid container is sealed off from an external environment.

A discharging apparatus for discharging loose and in particular pulverulent material that is hazardous to health from rigid or flexible containers (12), in particular bags and barrels (13), comprising a discharge chamber (2) which has a discharge opening (5) for discharging the material after removal from a container (12) and which additionally has an insertion opening (3) for at least partial insertion of a container (12) into the discharge chamber (2). According to the invention, the discharge chamber (2) has a ventilation opening (4) which is arranged at a side of the discharge chamber (2) opposite the insertion opening (3) and which is connected to pump means (10) in such a way that an air stream can be generated inside the discharge chamber (2), which causes a laminar air flow starting from the insertion opening (3) and leading in the direction of the ventilation opening (4).

A dust filtering and collection system for filtering dust and other debris particles from an incoming dust laden air stream, such air stream generally being used for conveying granular material into or from a bulk tank trailer, a railroad car, or other conveying vehicle, the filtering system designed to be functioned by vacuum air pressure, operatively generated by a blower, to draw in the soiled air into the filter system, to cleanse such air for further use in the conveying of the granular material. The air flow may be reversed, to provide for a dislodging of any dust particles from the filtering system, and to cleanse the filter for further efficient usage of the system in conveying granular material into or out of the tank trailer, or other vehicle during usage. The filter system includes a pod of filter tubes encapsulated by a polymer header that mounts to a transverse plate that secures to the approximate upper end of the filter canister of the filtration system.

Proposed is an apparatus for introducing an active material for use in a secondary battery. The apparatus includes a cutting unit positioned on an upper side of an introducing portion of a main hopper and provided for cutting a bottom portion of a packaging material in which a powder is accommodated, and includes a sealing unit provided around an outside of the cutting unit and configured to block leakage of the powder by bringing the introducing portion of the main hopper and an opening portion of the packaging material formed by cutting to be in communication with each other.

Closure unit (24) for a bulk material container (12), comprising a closure element (26) and a carrier unit (28) with a carrier element (30) and a emptying opening 34 arranged in the carrier element (30) and having a longitudinal axis of the opening (32).
wherein the closure element (26) can be moved between a closed position, in which the closure element (26) closes the emptying opening (34), and an open position, in which the closure element (26) at least partially opens the emptying opening (34).
wherein the carrier unit (28) has container connecting means (36) for non-destructively detachable arrangement of the closure unit (24) on the bulk material container (12),
and container system (10) with such a closure unit,
and emptying station (64) for a container system (10),
and container emptying system with a container system (10) and an emptying station (64).

A powder handling device is provided, along with apparatus and methods of its use. The powder handling device includes a mounting portion defining a plane and comprising a mounting interface; a fixture device configured to mount the mounting portion over an opening of a powder container at a mounting interface; and a powder suction unit attached to the mounting portion and passing through the plane. The powder suction unit is movable relative to the mounting portion with at least one degree of freedom. The powder handling device may be mounted onto an opening of a powder container.

A connection device includes a through-passage frame to guide goods through a through-passage, and a holding bag providing the goods. The through-passage frame includes a connection side, a rear side, an inner surface facing the through passage, and an outer surface facing away therefrom between the connection side and the rear side. When connected, the connection side faces the receiving port, the rear side faces away therefrom, and a through-passage direction extends from the rear to the connection side. The holding bag includes a film-type main body on the rear side which has a connection region connected to the through-passage frame via a connection. The film-type main body is guided from the rear side along the through-passage direction, through the through-passage, to the connection side, so that the connection region bears at least partially against the connection side, and the connection is arranged behind the through-passage along the through-passage direction.

A holder assembly comprises first and second tubular elements adjoined to each other, separated by an annular gap, and jointly surrounding an interior. A first clamping element extends radially outwardly around the first tubular element. A film tube can be guided out of the interior through the annular gap onto an outer side of the first tubular element, and be fixed in a sealing manner along a first circumferential line of the film tube by the first clamping element against a first contact pressure surface of the first tubular element. The film tube can be fixed in a sealing manner along a second circumferential line of the film tube in the annular gap. A gas outlet opens out of the outer surface of the first tubular element between the annular gap and the contact pressure surface, and in direct fluid-dynamic connection with an outer edge of the annular gap.

An isolator for emptying a container includes a connecting device for connecting the container containing a powder/granular product to the isolator; and a base body defining a connecting opening via which an opening of the container can be introduced at least in sections into an inner space of the base body from an outside environment. A connecting device includes a sealing device arranged at the connecting opening and has an adjustable sealing element. The adjustable sealing element is pressed against an outer wall of the container to produce a sealed state and is released from the outer wall of the container to produce an at least partially open state. A gap is formed between the sealing element and the outer wall of the container that an air flow directed into the inner space of the base body is generated due to the different ambient pressure.

A contained drum discharge system comprising a drum and connected with a lifting mechanism, wherein the drum includes a primary liner bag having the toxic powdery material to be disposed, contained within the secondary liner bag, and a tertiary liner bag enclosing the secondary liner bag; a transparent glove box; a hopper connected at a top of the glove box and with a vacuum transfer system of a material processing reactor; and a control unit connected with the glove box via a rotation mechanism and with the lifting mechanism of the drum. The glove box includes a plurality of glove ports connected with respective glove attachments; a plurality of thrashout ports with door; a sealing gasket to connect with the drum; a first liner port; a second liner port and a third liner port.
