A radiator screen device for a construction machine, an agricultural machine, or an industrial vehicle, each having a vehicle body and a radiator, includes a screen to filter dust contained in cooling air flowing toward the radiator, and a dust removing member disposed upstream of the radiator with respect to a flowing direction of cooling air and movable relative to the screen in contact with a surface of the screen to remove dust attached to the screen. The dust removing member and the screen are supported by the vehicle body. One of the dust removing member and the screen is vibrated relative to the other of the dust removing member and the screen by vibration of the vehicle body.

A system and method for removing retentate from filters is disclosed, which utilizes pressurized and/or vacuum fluid through localized application. The disclosure describes a cleaning system and sequence of steps for carrying out the cleaning process, whereby, a fluid is directed to flow through a localized region of the filter media, thereby dislodging and removing accumulated retentate from the filter. In addition, the localized application of fluid flow allows for localized monitoring of the cleanliness of the filter with a high degree of spatial resolution. This filter retentate removal system and method is broadly applicable to a wide range of systems and processes ranging to engines and exhaust systems to production plants and equipment.

A dust collector for use with a power tool comprises a housing, a telescoping suction pipe coupled to the housing, a suction fan positioned in the housing and operable to generate a vacuum in the suction pipe, a dust container coupled to the housing and positioned upstream of the fan, a filter at least partially arranged in the dust container, and a filter cleaning mechanism. The filter cleaning mechanism includes an anvil, a striker moveable between a first striker position, in which the striker is spaced from the anvil, and a second striker position, in which the striker is in contact with the anvil. The filter cleaning mechanism further includes an actuator moveable between a first actuator position and a second actuator position, in which the actuator is moved closer to the anvil than in the first position, and a first spring biasing the striker toward the anvil.

A filtration assembly (100) for a vacuum cleaner includes a filtration member (1) for filtering an impurity, in which an outer circumferential wall of the filtration member (1) is provided with a fixing frame (11) adapted to be fixed in the vacuum cleaner; and an ash tapping part (2) which includes a rack (21), a moving member (22), a gear (23) and a tapping member (24). Two ends of the rack (21) are fixed to the fixing frame (11), the moving member (22) is movably disposed to the rack (21), the gear (23) is disposed to the moving member (22) and meshes with the rack (21), the tapping member (24) is disposed to the gear (23) through a connecting shaft (241) so as to be driven to rotate by the gear (23), and the tapping member (24) is configured to tap the filtration member (1) during rotation to vibrate the filtration member (1).

An operation mode of an air cleaner is changed according to the degree of indoor air contamination and an indoor space condition, and one or more filters of the air cleaner can be easily cleaned. The air cleaner includes a housing, an inlet located at a lower part of the housing, a filter assembly, an outlet, and a brush unit. The filter assembly is located above the inlet, and a diameter of the filter assembly is gradually shortened in the direction from an upper part of the filter assembly to a lower part of the filter assembly. The discharge port is located above a second filter assembly. The brush unit is used to eliminate contaminants from an outer surface of the filter assembly.

A cleaning system and a base station. In a working process, an airflow is generated by a drawer, to draw garbage on the ground on a traveling path into a dust box. Before the airflow entering the dust box is discharged outside a cleaning robot, the airflow flows through an air filter, and dust carried by the airflow is filtered out under a filtering function of the air filter. When dust accumulation in the air filter needs to be cleaned or the dust box needs to be emptied, the air filter is driven by a dust cleaner to vibrate, so as to shake off dust in the air filter, and the garbage in the dust box is collected by using a collector of the base station.

A system for filtering a gas-solids mixture, comprises: a housing; a separating body dividing the housing in a raw gas chamber and a clean gas chamber, the raw gas chamber being accessible via an inlet for the gas-solids mixture and the clean gas chamber comprising an outlet for discharging a cleaned gas; a number of filter elements suspended from the separating body; lower ends of the filter elements being connected to a support grid, the support grid comprising a number of arms; one or more cleaning elements provided on the arms of the support grid for cleaning thereof.

A vacuum cleaner and filter cleaning system includes a filter cleaning mechanism which allows the filter to be cleaned without removal from the vacuum. Operation of the filter cleaning mechanism both flows air backwards through the filter and strikes the filter to more effectively clean the vacuum filter. The vacuum allows for filter cleaning and debris disposal without significant interruption of the use of the vacuum cleaner.

A dust removal device includes: an upper cover, a base, a support body, and a dust collector. The support body couples with the upper cover and the base. The dust collector includes: a first connecting member, a second connecting member, and a dust collecting body. The dust collecting body is coupled with the first connecting member and the second connecting member and has a folded structure. When an external force enables a shape of the first dust collecting body to be changed, a distance between the first connecting member and the second connecting member is also changed. In a cleaning mode, the dust collecting body is stretched and compressed in a reciprocating manner by using a structure of the dust collecting body.
