A cleanable filtration system for an air conditioning system includes a continuous filter positionable adjacent to an inlet opening in the air conditioning system and a drive system operably coupled to the continuous filter to move the continuous filter relative to the inlet opening. A cleaning jet is positioned to spray a cleaning fluid on an adjacent portion of the continuous filter.

A system for cleaning a filter mounted over an intake opening of an air handling unit. A conduit is secured to an elevated location of the unit and includes a plurality of spaced nozzles arrayed against the filter. A supply tube connects to the conduit for supplying a pressurized fluid through the nozzles in order to clear debris from an exterior of the mounted filter. The pressurized fluid includes either of water or compressed air provided from any of a source or a supply reservoir. A pump is incorporated into the supply tube for pressurizing the fluid. A filter incorporated into the supply tube filters the pressurized fluid prior to delivery to spray issuing conduit.

Filter media for a drum filter that includes a plurality of annular frame members, each annular frame member having a circumference is disclosed. The filter media includes a filter sheet with first and second engagement strips having a cord portion and an attachment tab portion connected to the filter sheet. The first and second engagement strips engage with first and second connecting strips located on the annular frame members. Each connecting strip has a receiving portion that receives the cord portion of the associated engagement strip. Each connecting strip also has a body portion configured to engage a drum filter frame. An engagement mechanism configured to attach a filter sheet to a drum filter frame is also disclosed. A system for attaching a filter media to a cylindrical drum filter is also disclosed. When the first and second engagement strips are fully received in the first and second connecting strips, the filter media extends between the first annular frame member and second annular frame member and along the first and second circumferential edges to enclose a first cylindrical filter space.

This application provides a filter cleaning system, a filter cleaning method, and a data center. The filter cleaning system includes a first filter, a first-stage cleaning unit, a sensing unit, a control unit, and a second-stage cleaning unit. The first-stage cleaning unit includes at least one of an adsorption assembly, a washing assembly, or a brush assembly. The second-stage cleaning unit includes a motor and a mandrel assembly that includes a second filter, and is configured to replace at least one part of the first filter with a part of the second filter. The control unit is configured to control, based on a pressure parameter that is of two sides of the first filter and that is obtained by the sensing unit, the first-stage cleaning unit and/or the second-stage cleaning unit to work.

A cleaning apparatus of a work machine for cleaning debris from a screen mounted to a door of an engine cooling assembly. The cleaning apparatus includes a duct extending along the screen and along a first side of the door. The duct includes a duct end located at the door. A vacuum assembly is configured to draw a vacuum through the duct, wherein the vacuum assembly is detachably connected with the duct end. An alignment mechanism includes an aligner that extends from the duct to a frame of the work machine. The alignment mechanism aligns the duct end with the vacuum assembly to provide a seal between the duct and the vacuum.

The present application proposes an air purification device with filter cartridge self-cleaning, which includes: cabinet, air filter cartridge and centrifugal fan, a first mounting plate and a second mounting plate are arranged in the interior of the cabinet from top to bottom, the first mounting plate and the second mounting plate divide the interior of the cabinet into a first chamber, a second chamber, and a third chamber, the cabinet is provided with an air inlet communicating with the first chamber, and with a plurality of air outlets communicating with the third chamber; the air filter cartridge is arranged in the second chamber, the air filter cartridge includes an end cover, a bottom cover and a filter cylinder, and the two ends of the filter cylinder are respectively connected with the end cover and the bottom cover, and the filter cylinder is used for filtering and purifying the air, a cleaning assembly is arranged in the filter cylinder for removing dust adsorbed on the filter cylinder; the centrifugal fan is installed in the third chamber. In the present application, a negative ion generator is arranged in the cabinet, and the negative ion generator generates negative ions to charge the dust in the air, so that the charged dust is adsorbed on the air filter cartridge during the air flow process, the air through the air filter cartridge is cleaned to achieve air purification.

An agricultural equipment air screen cleaning assembly having a frame having an airflow opening having a non-circular outer perimeter, a screen mounted to the frame within the airflow opening and extending to the non-circular outer perimeter, a motor, and a suction wand operatively connected to the motor and located on an upstream side of the screen. The suction wand is rotatably connected about a rotation axis at a central region of the screen, and includes: at least one distal end that is movable in a radial direction with respect to the rotation axis to follow the non-circular outer perimeter as the suction wand rotates about the rotation axis, one or more inlet openings facing the screen, and an internal suction flow path in fluid connection with the one or more inlet openings, the suction flow path extending from a manifold to the distal end of the suction wand.

The filtering apparatus includes: a casing having an inlet for a fluid from the outside and an outlet for the fluid having filtered therein; filter elements having opposite-end openings, provided in the casing, and each filtering the fluid by allowing the fluid to flow therethrough in inside-to-outside directions; backwashing pipes sequentially connected to the opposite-end openings at different timings between the opposite-end openings of each filter element so as to backwash the filter element by allowing the fluid to flow therethrough in outside-in directions; removers each axially moved in the corresponding filter element by the filtration or backwashing flow, while sliding in contact with the inner periphery of the filter element so as to remove trapped objects; and a backwashing fluid drain pipe coupled to the discharge side of the backwashing pipes and allowing the trapped objects removed by each remover to be discharged to the outside.
