A method and apparatus for removing particles, such as dust, generated by a moving web is disclosed. A dust control platform is positioned adjacent to a traversing web to catch the particles generated by the web. The particles pass through one or more apertures defined by an accumulation surface. The particles pass through the accumulation surface and into an accumulation chamber. The accumulation chamber may include a sweeping device or other device that may be used to transfer the accumulated particles to a collection chamber. The collection chamber is connected to a vacuum source. Vacuum is applied to the collection chamber by the vacuum source such that the particles are removed from the collection chamber.

A dust hood for a dust control system includes a first hood body and a second hood body. The first hood body and the second hood body are each selectively movable between an assembled position and a disassembled position. In the assembled position, the first hood body is adjacent to the second hood body. In the disassembled position, the first hood body is spaced apart from the second hood body.

A high volume dust collector that is adapted and configured to reduce time associated with routine cleaning of an industrial tissue-machine and factory. The dust collector has a body, having an intake positioned to draw large volumes of air and dust from any area where dust is known to accumulate when engaged. The intake is taller than it is wide and is fitted with a grill to prevent larger maculature from clogging the system. An outlet on each collector connects to a fan or blower and sends collected dust to filtration system. An access hatch is positioned on the body of the collector to allow an operator to manually clear any clogs, should they occur.

A packaging machine for making filter bags with infusion products including a plurality of processing stations and a cleaning unit. The processing stations define a processing path and are configured for making infusion products. The cleaning unit is configured for removing dust from the processing path and in turn includes a generator device positioned above the processing path and configured for generating a flow of air designed to push the dust beneath the processing path; at least one ventilation grille coupled to the generator device and designed to convey the flow of air along a predetermined direction of emission which extends around the processing path and at least one suction device positioned the processing path and configured for sucking the dust promoting the evacuation from the machine.

An air-blowing roller includes: a roller body, where a plurality of air outlets are disposed on an outer peripheral surface of the roller body, the plurality of air outlets are arranged along an axial direction of the roller body, an air exhaust direction of the air outlets is tangent to the outer peripheral surface of the roller body, and air exhaust directions of the plurality of air outlets are consistent. A dust removal apparatus includes a conveyance mechanism, an air-blowing roller assembly, and an air intake roller assembly.

A cleaning head is disclosed for use in a traversing shower system. The cleaning head includes a plurality of directional fluid nozzles for discharging a fluid, each of which is provided along a different direction toward a work surface such that no two directions cross one another between the cleaning head and a working surface.

Provided are a foreign substance removal method and foreign substance removal device that have excellent continuous operation stability for sheets and excellent foreign substance removal performance, during removal of foreign substance. Suction boxes (3a, 3b) are arranged at a position between two conveyance support bodies (1a, 1b) having an arrangement interval fulfilling prescribed conditions, said position having vertical symmetry relative to the sheet (2). Air is jetted towards the sheet (2) from air nozzles (4a, 4b) arranged inside the suction boxes (3a, 3b). Foreign substances are detached from upon the sheet (2) and the detached foreign substances are recovered using suction air having an average suction airspeed of 0.8-1.2 m/sec from openings (5a, 5b) in the suction boxes (3a, 3b).

The present invention relates to a cleaning arrangement for a nozzle of a vacuum cleaner. The cleaning arrangement comprises a socket for receiving the vacuum cleaner nozzle and a cleaning member arranged in the socket for removing articles entangled to a rotatable member of the vacuum cleaner nozzle during rotation of the rotatable member.

A system for capturing dust during the movement of sand between a container and a fracing blender includes a conveyor system having a lateral portion for transporting sand discharged from the container, a lifting portion for lifting sand received from the lateral portion, and a spout for discharging sand received from the lifting portion into a bin of the fracing blender. An enclosure encloses a substantial length of the lateral portion of the conveyor, with portions of the enclosure disposed above and along opposing sides of a belt of the lateral portion of the conveyor system. A manifold is supported on the ground and is coupled in fluid communication with a flexible conduit, which has an inlet disposed in an area proximate a discharge end of the spout. An air system is coupled in fluid communication with the manifold and the flexible conduit for drawing air through the inlet of flexible hose to capture dust around the discharge end of the spout. A collapsible cover is disposed over the discharge end of the spout and the bin of the blender.

A vacuum system having a housing defining a collection chamber with a filter assembly mounted therein. The housing has a suction inlet and an exhaust port defined therein and in gas communication through the filter assembly. The vacuum system also includes a suction device having a motor operatively connected to a suction fan configured to generate a gas flow in the housing. The vacuum system also includes a rotor configured to engage the filter assembly in vibration upon rotation of the rotor. The vacuum system also includes a recirculation conduit having a valve configurable in a vacuum configuration preventing the gas flow from flowing through the recirculation conduit and a cleaning configuration allowing at least a portion of the gas flow to flow through the recirculation conduit to engage the rotor in rotation. A method of vacuuming using the vacuum system is also provided.
