A filter device for removing particles from a fluid includes a fluid chamber and an inlet for fluid, an outlet for filtered fluid and an outlet for particles, each coupled to the fluid chamber. The filter device also includes a flow directing mechanism for inducing a vortex flow around a vortex axis in the fluid chamber. The outlet for particles is coupled to the fluid chamber at a location substantially perpendicular to the vortex axis.

A suction apparatus includes a housing, at least one cyclone chamber, a collection container configured to as to be releasably connectable to the housing, and having a filter element. The suction apparatus further includes at least one positioning device within the cyclone chamber and configured for positioning at least one collection element within the cyclone chamber.

A surface cleaning apparatus has an air flow path from a dirty air inlet to a clean air outlet. The air flow path comprising an air inlet conduit which extends downstream from the dirty air inlet. The Surface cleaning apparatus has a first stage cyclone and a second stage cyclone downstream from the first stage cyclone, the second stage cyclone having a plurality of air inlets. The cyclone axis of rotation of the first stage cyclone extends through the air outlet of the second stage cyclone. the first stage cyclone, the second stage cyclone having a plurality of air inlets, an air outlet and a cyclone axis of rotation. A plane that is transverse to the axis of rotation of the second stage cyclone extends through the inlet conduit and the air outlet of the second stage cyclone

Disclosed are a base station and a cleaning equipment. The base station includes: a first box defined with a sewage inlet for solid-liquid mixed garbage to enter the first box; a second box communicated with the first box, for receiving liquid garbage from the first box; a cyclone separator communicated with the first box; and a fan communicated with the cyclone separator, the fan is configured to drive an external airflow into the first box from the sewage inlet, and drive the external airflow to enter the fan after passing through the cyclone separator, such that the solid-liquid mixed garbage enters the first box through the sewage inlet.

A particle separator is provided for separating small particles from large particles from material. The particle separator includes a conical shaped separator housing that forms a cyclonic separator enclosure, a cover attached at a top portion of the cyclonic separator enclosure, and an opening at a bottom portion of the cyclonic separator enclosure. The cyclonic separator enclosure has an inlet tube with a tangential entry opening along an inner wall of the cyclonic separator enclosure, where the inlet tube projects horizontally outward from an upper portion of the cyclonic separator enclosure. An outlet tube extends upward from a center of the cover with a vacuum unit connected to the outlet tube that creates a vortex in the cyclonic separator enclosure.

A surface cleaning apparatus includes a cyclone having a plurality of tangential air inlets. Each tangential air inlet is formed of a sidewall and an end wall. The tangential air inlet has an inlet port which is positioned to face a wall of the cyclone chamber. The tangential air inlets have a flow straightener provided on a radial inner or outer side.

Separators for separating a multi-phase composition include a separator casing defining a chamber and a permeate outlet, at least one hydrocyclone within the separator casing, and at least one ceramic membrane. Each hydrocyclone includes a hydrocyclone inlet, a tapered section downstream of the hydrocyclone inlet, an accepted outlet, and a reject outlet. The ceramic membrane may be disposed within the separator casing and downstream of the accepted outlet of the hydrocyclone or may be disposed within at least a portion of the tapered section of the hydrocyclone. The ceramic membrane includes a retentate side and a permeate side, where the permeate side is in fluid communication with the chamber. Systems and methods for separating a multi-phase composition into a lesser-density fluid, a greater-density fluid, and a medium-density fluid using the separators are also disclosed.

A cleaner includes a suction unit guiding air and dust, a main body including a first cyclone unit separating the air and the dust, which are suctioned through the suction unit, from each other and a second cyclone unit separating the dust from the air discharged from the first cyclone unit, and a guide unit disposed in the main body to partition a first dust storage part, in which the dust separated in the first cyclone unit is stored, and a second dust storage part, in which the dust separated in the second cyclone unit is stored, from each other. The guide unit is separably coupled to the main body, and when the guide unit is separated from the main body, a dust discharge part of the second cyclone unit is exposed to the outside.
