CENTRIFUGAL FILTER.
Application filed. May 4,
My invention relates to improvements in centrifugal filters. The object of the invention is to provide a continuous lilter which shall be oi simple construction, easily maintained, readily accessible internally, and highly el'iicient.
The structure embodying the invention and the means employed in the attaiment of the aforegoing objects will be clearly understood on reference to the drawings that form part of this specification; and in which ig. l is a vertical section of a large capacity, centriil ugal lilter embodying my invention. 2 illustrates the top of the centniugal unit or member of the apparatus, as seen from the line 22; Fig. 3 is a horizontal section on the line of Fig. 1; and Fig. l is a horizontal section on the line l4 thereof.
The apparatus is of such simple construetion that it comprises only four essential parts, namely: the members A, B, C and 1). These will be described in detail.
The conical member A is the fluid admission head of the filter, and contains the preterably integral fluid spreading or directing cone A. The bottom of the cone A stands slightly above the under surface of the flange A.
The member G is a removable section which contains the niember B. The internal diameter ot the member C is the same as the lower end of the member A. The top flange G or the member C is joined to the member her 0 contains the internal rib or flange C having a beveled bottom C and containing the large central. opening (3*. As herein shown the lower end of the member B is preferably polygonal, the opening C is of corresponding shape to receive it.
The top or the member C is provided with sinks or notches C that will be referred to later. The lower end of the member C is marked by the flange C The member D is bulbous in shape to pro vide a large collection cavity D and has a top or neck portion D The latter is marked by the top flange D which is connected to the flange U by the bolts 3. At the bottom oil' the member .D is a nipple D which receives a drain pipe The portion 1) is a beveled flange or collar surrounding the initial outlet- D of the filter. That outlet 1925. Serial No. 27,863.
may be tapered as shown. The member 1) stands so far below the rib C as to provide a circumferential gap or race D which is in direct communication with the cavity 1) through the annular opening or slot 1) between the periphery of the flange D and the neck portion D The terminal outlet D of the filter is preferably in the side of the part D and is connected with the opening D by the integral elbow or curved pipe D. This construction is convenient for several reasons and makes it possible to employ a central discharge or drain at the bottom of the bulbous pocket D. However, when it is desired the flow orliquid may be directly downward through the bottom of the filter.
The part B is a tangential tuyere ring or barrel which serves to set the downward flowing fluid into rapid rotation in a plane transverse to thelongitudinal axis of the filter and directly above the initial outlet D The ring or barrel B is generally cylindrical being mainly composed of a circumferential series of overlapping tuyere blades 5 Together these form a large number of slit-like longitudinal and tangential tuyeres B which receive the fluid from the circumferential space C within the member C. At their lower ends the tuyere blades are notched as shown in Figs. 1 and 3 and are attached attached to a flat-sided or polygonal ring B That is the polygonal part which occupies the before-mentioned polygonal hole G at the bottom of the member 0.
The lower ends of the blades rest on the top of the rib G The upper ends B of the blades B are bent outward (see Fig. 1) and are attached to the margin of the top plate B*. The bottom of the latter is preferably characterized by a peripheral retaining groove B. For centering the member B in the member C and partly to carry the weight of the member B, I employ project ing arms 13 on the top 13*. The ends of the arms B are accommodated in the notches C and the whole top is below the level of the flange A".
The member A is flanged for connection with the inlet pipe 4, likewise the member D is flanged for connection with the outlet pipe 5. These connections are permanent and need not be disturbed when it is desired to remove the member B and get at the interior of the members A, C, and D. For such purposes the bolts 2 and 3 are removed and the member C is drawn out from between the members A and D. Obviously, the member B is wholly contained within the member C and is removed therewith, and likewise replaced therewith.
The parts being assembled as shown in Fig. l and a stream of water or other fluid being admitted at the top, the filtering action at once begins at the member B. As will be apparent the downward flowing fluid sub-divided into many thin longitudinal streams which enter the member B tangentially and at relatively high velocity. Each stream immediately impacts the angularly V disposed succeeding blades B and the first centrifugal separation of the heavier substancesis immediately accomplished. It will be understood that the whole filter is filled with liquid and that the tangential movement of the streams within the member B organizes and maintains a swift whirling action of the fluid therein and also in the circumferential gap or race D Thereby the initial separation of the heavier from the lighter components of the fluid is maintained and completed. And as the whirling fluid moves downward toward the outlet D the peripherally separated heavier substances are centrifugally ejected into the ci rcum ferential race D thence to settle into the cavity D.
Meantime, the purified fluid constantly leaves the filter through the outlets D and D. The heavier substances collected in the cavity D may be blown off continuously or discharged intermittently, as desired. A
special advantage of the bulbous bottom resides in the fact that the contents thereof takes on a considerable whirling motion from the contents of the race D and as a result the heavier substances descending through the annular slot or opening 1) quickly move outward beneath the overhanging top of the bulbous member D and are thus effectively prevented from returning to the opening D Having thus described my invention I claim as new and desire to secure by Letters Patent 2- 1. A centrifugal filter comprising a fluid admission head in combination with a collection pocket below the same, a removable member between said head and pocket, a fluid-whirling member wholly contained within the removable member, a central outlet pipe having a lateral flange at its top and positioned in the top of said pocket below the said fluid-whirling member, and a drain for said pocket.
2. A centrifugal filter comprising a conical fluid admission head in combination with a bulbous collecting pocket, an intermediate member joining said head and pocket and which is removable laterally between said head and pocket a fluid-whirling element positioned in said intermediate member and an outlet pipe positioned in said bulbous member and presenting an outlet orifice centrally below said intermediate member and said fluid-whirling element.
In testimony whereof I have hereunto set my hand this 30th day of April A. D. 1925.
