A BASKET STRAINER
Summary of the Invention This invention relates to a strainer for filtering liquids and provides for a removable filtering element.
The strainer includes a housing having side and bottom walls and a top opening which receives the filtering element.
Inlet and outlet ports serve to maintain liquid communication through the housing. One of the ports includes an upturned section within the housing. A removable cover spans the top opening of the housing. The filtering element includes a reticulated body having an open upper end which contacts the upper end of the upturned port section to place the filtering element in a liquid flow path between the inlet and outlet ports whereby liquid entering the housing will flow through the filtering element and out of the housing through the outlet port.
The strainex may be cleaned by removing the co~er from the top opening of the housing and lifting the filtering element out of the housing. The filtering element preferably includes a narrow strip of material which spans the open upper end of the element. The strip serves as a handle for lifting the filter-ing element from the housing`~and is constructed to contact the cover to retain the filter body upper end in contact with the upper end of the upturned port section.
It is an object of this invention to provide a strainer for liquids having a removable filtering element within a filter housing.
Another object of this invention is to provide a filter having an upturned internal port section which at its upper end contacts the open upper end of a filtering element in such a manner that the filtering element may be easily and quickly lifted from within the filter housing for cleaning . ,.
i~, or replacement.
Other objects of this invention will become apparent upon a reading of the following description.
Brief Descri~tion of the Drawings A preferred emhodiment of the invention has been chosen to best illustrate the principles of the invention wherein:
Fig. 1 is a side view of the filter assembly.
Fig. 2 is a fragmentary top view of the filter assembly with a portion of the cover cut away for purposes of illustration.
Fig. 3 is a cross-sectional view taken along line 3-3 of Fig. 2.
Fig. 4 is a cross-sectional view of the filter assembly housing with the cover removed and the ~ ilterin~ element raised for purposes of illustration.
Description of the Pre~erred Em odiment The preferred embodiment illustrated is not intended to be exhaustive or to limit the invention to the precise ~orm disclosed. It is chosen and described to best explain tha principles of the invention and its application and practical use to thereby enable others skilled in the art to best utilize the invention.
The strainer 10 includes a housing 12, defined by a side wall 14 and a bottom wall 16, and a removable corner 20 which spans a top opening 1~ in the housing. Cover 20 is fastened to housing 12 with hold down bolts 13 and nuts 15. Housing 12 includes an inlet port 22 through which liquid enters and an outlet port 24 through which filtered liquid exits. Each port 22, 24 includes a mounting flange 23 ~or connection to external piping. The housing includes an upright cylindrical ~ 2 ~z~
section 26 which is in sealing contact at its bottom edge with housing bottom wall 16. Upturned portion 26 includes an inwardly projecting annular lip 38 at its upper end. Lip 38 can have an annular groove 40 formed in its upper surface.
An O-ring seal 42 is fitted within groove 40. Outlet port 24 extends through housing side wall 14 and is connected into cylindrical section 26 near its lower end.
A filtering element 28 is seated within housing 12 and includes a reticulated, generally rigid basket-shaped body 29 having an opening 30 in its upper end defined by an outturned lip 32. Filt~ring element 28 is suspended within housing cylindrical section 26 by its lip 32 being supported upon lip 38 of the cylindrical section with the side and bottom of its body 29 preferably spaced rom the cylindrical section.
~n arched strip 33 of flexible shape-retaining material spans the opening 30 of filtering element body 29 and is attached at its ends to lip 32.
In the embodiment shown, with filtering element body lip 32 resting upon housing cylindrical section lip 38 to suspend filtering element body 29 within the cylindrical section, strip 33 of the filtering element will contact cover 20 when the cover spans housing opening 18. This pressure of cover 20 against strip 33 maintains contact bet-ween filtering element 28 and housing cylindrical section 26.
The liquid,as shown by flow arrows 44, enters housing 12 through inlet port 22, fills the space 45 between cylindrical portion 26 and housing side wall 14, and flows into filtering element 28 at its open end 30. The iiquid then flows out of housing 12 through reticulated filtering element body 29, cylindrical portion 26, and connected outlet port 24.
To change or clean the filtering element 28, cover 20 is removed by removing hold down nuts 15 from bolts 13.
,~
~ 2~
Filtering element 28 is then pulled upwardly, as seen in Fig. 4, from housing 12 by grasping strip 33 with the filtered or strained material remaining within filtering element hody 29. In some operations, it may be desirable to use a flexible filter bag within filtering element body 29.
It is to be understood that the invention is not to be limited to the above description but may be modified within the scope of the appended claims.
