An auto-cleaning marination filter for a poultry injector system including an outer housing having a liquid inlet and outlet, a screen that allows passage of liquids and impedes passage of solid particles, and a wiper surrounded by said screen for removing solid particles attached to the screen by reverse flow of the liquid through a gap in the wiper.

A pipeline strainer having a body with a straining element therein. A cleaning tool is disposed in the body to dislodge debris from the straining element. The debris may be removed from the body through a debris drain. The cleaning tool comprises a portion within the body and a portion outside of the body. A handle may comprise the portion outside of the body.

A spiral seal continuous discharge filter for supercritical water treatment process is provided, including: a filter chamber and a motor 1 provided on a top of the filter chamber; wherein a liquid inlet is provided on an up portion of a wall of the filter chamber, a filter screen is provided in the filter chamber, a purified liquid outlet is provided on an external side of the filter screen, a vertical discharge pipe is provided on a bottom portion of the filter chamber, a driving rod rotated by driven of the motor is provided on a central axis of the filter chamber, a plurality of electric scratch brushes are provided on the driving rod, and a two-stage spiral blade unit is provided on a bottom of the driving rod.

A device for filtering ballast water which performs filtering by installing a filter element having a conical shape in a concentric circle direction inside the device for filtering ballast water that accommodates a filter portion, and introducing ballast water from a lower end of the device for filtering and passing same through the filter element inside the device for filtering, and for discharging backwash water containing foreign substances that are inside a filter by ways of differential pressure, which is created by a driving portion communicating with a filter element by rotating an aspiration portion that is located on the lower end of the device for filtering. In particular, the present invention relates to a candle-type device for filtering ballast water, wherein the driving portion is positioned on a lower portion of the housing so that more filter elements can be accommodated inside the housing.

A filter device has filter elements (23) received in a filter housing (1) with a filter inlet (19) and a filter outlet (21). Flow passes through the filter elements (23) for a filtration or backwash in both directions. At least one filter element (23) performs the filtration. At least one other filter element (23), for cleaning off its active filter surface, can be backwashed by a backwash appliance. For supporting the backwashing, the appliance contains a pressure control (43) having a pressure control element (45). During a backwash operation, the fluid flow is controllable in a fluid connection between filter inlet (19) and the filter element (23) that is to be cleaned off. The fluid connection has a connection space (29) having element openings (27), each of which can be connected to an open end of the filter cavity forming the unfiltered side of each filter element (23). A fluid pathway (27) is provided via which, during the filtration, unfiltrate flows into the connection space (29). By the pressure control element (45), the flow of unfiltrate through the element opening (27) associated with the filter element (23) that is to be cleaned off can be controlled.

An oil filter assembly is disclosed for a machine, such as an internal combustion engine, that has an oil output port and an oil input port. A mounting plate may be fixed with an outer enclosure and may be adapted for securing to the machine. The mounting plate may be further adapted to conduct oil from the machine into a peripheral portion of the outer enclosure, and then returning oil from a central portion of the outer enclosure back to the machine. Oil may pass from the peripheral portion to the central portion through a primary filter having a first porosity. A pressure-actuated valve may be fixed fluidly between the peripheral portion and central portion of the outer enclosure. Oil may pass through the pressure-actuated valve only when an oil pressure differential between the peripheral portion and the central portion of the outer enclosure exceeds a predetermined threshold pressure. A secondary filter may have a second porosity greater than the first porosity, and may be fixed fluidly between the pressure-actuated valve and the central portion of the outer enclosure.

A filter element may include a tubular member including a partition at least partially defining first and second chambers. The tubular member may further include at least one outlet aperture and at least one inlet aperture configured to provide flow communication exiting from the first chamber and flow communication into the second chamber, respectively. The filter element may be configured such that fluid passing through the filter element from an inlet port to an outlet port passes through the first chamber, a filter medium, and the second chamber. The filter element may also include an end cap having a return aperture configured to provide flow communication between fluid exiting from the first chamber and fluid entering the inlet port, wherein a portion of fluid exiting from the first chamber is returned to the inlet port for recirculation through the first chamber.
