SUCTION STRAINER
A tank for storing oil includes a suction strainer with first and second filtration portions. The first filtration portion has a substantially cylindrical shape and formed by bending a thin plate into a pleated shape. The second filtration portion is provided on the outer side of the first filtration portion. The second filtration portion has a substantially cylindrical shape and is formed of a material having a plurality of spaces formed in a surface and interior of the material.
Modular filter cassette
The present disclosure relates to modular filtration cassettes for filtering liquids including, for example, liquids used in semiconductor manufacturing. A filter housing may define a filter cavity comprising an upstream portion and a downstream portion. The filter may further comprise a filter element disposed in the filter cavity. The filter element may at least partially overlap the filter inlet on a first side of the filter element. The filter element may comprise a rectangular pleated filter with a set of pleats having a first set of pleat tips on an upstream side of the filter element and a second set of pleat tips on a downstream side of the pleated filter.

SUCTION STRAINER
In a suction strainer, a filtration part is provided along a horizontal direction, a first end member includes a first attaching portion having a plate shape provided at a side surface of a tank, a second attaching portion provided with a filtration part, and a first hole configured to communicate a hollow part of the filtration part and the outside of the tank, the second attaching portion, the filtration part and a second end member are provided inside the tank. The second end member includes a plate-shaped part configured to cover the hollow part of the filtration part, the plate-shaped part is provided with an air vent hole, and the float is provided in such a manner that the float is movable in the horizontal direction between a position of closing the air vent hole and a position of opening the air vent hole.
Filter cartridge endplate with integrated flow structure
A filter cartridge endplate (12) is described herein that has an integrated flow structure. For example, the integrated flow structure has concentric flow portions disposed at a center of the endplate (12), where a separator (10) is built into the endplate (12) that separates fluid flow. The endplate (12) includes a plate with a major surface, a separator (10) that protrudes axially away from the major surface. The separator (10) includes a first flow portion (14) and a second flow portion (16), where the first flow portion (14) is disposed radially inward relative to the second flow portion (16). The first flow portion (14) includes a channel (22) and the second flow portion includes a channel (24). The respective channels (22,24) are configured to allow axial fluid flow relative to the plate, and configured to allow fluid flow that is localized toward the center of the plate (12).
Sieve box and adjustable nozzle assembly
An adjustable nozzle assembly for a sieve box and a sieve box including same, including a support assembly and nozzles. A pair of elongated support members may be received through openings in support collars. Nozzles may be operatively connected to the collars. The support assembly, which may include collars and rods, are configured to provide at least one of lateral movement and rotational movement of the nozzles. At least one of the first elongated support member and the second elongated support member may be configured to move when coupled to the sieve box to adjust a spray angle of the nozzles. Pivoting of the one rod about the other rod adjusts the angle at which the nozzles are disposed. The rods may be externally threaded, and the collars may be internally threaded, such that when the rods are rotated, the collars translate laterally along the rods to move the nozzles.
Liquid filter, and a liquid filtration apparatus using the liquid filter
A liquid filter and a liquid filtration apparatus are provided using the liquid filter, which enable uniform filtration over the entire range, without localizing a part where filtration occurs to the upper side above the middle. The liquid filter has a plurality of spacers fixed to a filter body. The filter body has a liquid inflow space, a plurality of diagonal fold parts individually formed outwards from corner parts of the liquid inflow space and having a length in the radial direction around the center of the liquid inflow space, and pocket parts having any one of the diagonal fold parts as one side, and individually having a triangular planar shape, and the spacers are fixed on the inner face of the filter paper, near the diagonal fold parts, and inside of the individual pocket parts.
