Abstract: Dust separation devices are disclosed to enable separating and collecting dust particles. The devices include a vacuum port and a cyclone chamber that are connected by a tube between the vacuum port and an upper end of the cyclone chamber. On the cyclone chamber there is an input port for connecting to a hose for ingesting the dust particles. The devices also include a dust receptacle having a top upper surface and a port cover on a port formed in the upper surface for emptying the receptacle of collected dust particles and a lower portion of the dust receptacle that is integrally formed into the upper surface of the dust receptacle.

Abstract: Dust separation devices are disclosed to enable separating and collecting dust particles. A parabolic cyclone chamber is disclosed. The parabolic cyclone chamber has a bottom having an opening, an upper surface, a curved sidewall connecting the bottom to the upper surface, an entry path in a top portion of the cyclone chamber, an exit path extending through the upper surface, and a diverter wall sloping downward from the upper surface of the cyclone chamber toward the entry path.

Abstract: Monolithic dust separation devices are disclosed to enable separating and collecting dust particles. The devices include a vacuum port and a cyclone chamber that are connected by a tube between the vacuum port and an upper end of the cyclone chamber. On the cyclone chamber there is an input port for connecting to a flexible hose for ingesting the dust particles. The devices also include a dust receptacle having a top upper surface and a port cover on a port formed in the upper surface for emptying the receptacle of collected dust particles and a lower portion of the dust receptacle that is integrally formed into the upper surface of the dust receptacle. The top upper surface slants downward from the cyclone chamber to the port cover.
