This invention relates tofliqui'd strainers andimore particularlyy to an apparatus especially adapted for use in strainingcane juices for usein sugar making with a view to sep- .ar-ating therefrom trash or cane fibre con-A tained in the liquid as removed from` the crushing rolls.` 1
An importantobject of the invention-is ythe improvement of an apparatus disclosed in my '1o prior UnitedV States Patent, No. 1,594,999 granted August 3, 1926, for juice strainer, to increase the eiiciency'thereof inthe straining operation. j
-A further and more specific object kofthe invention is the provision of a construction lpreventing splashing ofvdirty liquid ,into the liquid which has been treated by the screening apparatus.
A further objectv of the invention is the pro'- vision of kan improved inletl for such screening devicesy whereby the incomingfliquid is more' evenly distributed along thescreen and pilin upy of the liquid at one end thereof avoi ed.
A still further obj ect of the invention is the provision of an inlet or supply pipe khaving auxiliary supply' pipes associated therewith and disposed within `the l screening apparatus which are so arranged that the extent' to which the liquid is distributedfover thersur-` face of the screen. is increased. v A still further object ofthe invention is'to provide a construction permitting the use' of L, a closedT tank' for the screening apparatus.y A further` objectof the inventionis the provisionfof' an improved screen structure both in the general make-upthereofand in the rmanner of mounting 'the' saine" upon'- the support-v m ingendcastings.'
These and other objects VI attainby the construction shown in the accompanying drawings wherein,- forthe'purpose of' illustration,-I have shown a preferred embodiment of-myinvention and 'wherein z Fig. 1 is a side elevation' taken' on'the line' 1-"1 of Fig. 2 ;V l
Fig.2 is a transversefsectionalview through the juice straining apparatus Figp is an' end view showing driving' mechanism j Fig. 4 'is a -vie'w'fof one'of thefsc're'en'segl ments ;1and j Fig; 5 is an enlargedfragmentaryview of the screen inse'cti'on showingthefconstruction of the" screen;y l
Referring now' more particularly to the drawings', lthe"nunie'ral 10 generally idesg nates a substanti allyl semi-'cylindrical'trough, the upper edges 'of which 'are provided with int'urne'd flanges' or"should'e`rs 11./ A semicylindricaltop 12 is provided fortheitfrougli which is' hinged tothe 'shouldersy 11 at points spaced inwardly from' the edges of the trough as atf13 and whichisformed in two sections joining at their' top" as at 14,which may be separated and swung down at opposite sides;Y ofthe t'ankfto permit accessfto the yscr'eening apparatus hereinafter to? bei-described.'v heads '15 are provided closing the endso'fthe` trough and of 'the'f semi-cylindrical'cover12 thereof.'
The' screening apparatus comprises rend castings 16v each includinga roller track 17 havingassociated?therewith a gear 18 formed at one edge of thev track-Lv Projecting inwardly froml the roller track'is a cylindricaln flange 19 the p'erip'heryo'f Whiclii's notchedat spaced intervals as indicated at 2O vto provide seats for longitudinallyextending, lreinforcing and spacingribs`21- preferably in T form and consistingeither of solidbeam'or an asi sembly ofbea'ms *j Projecting' inwardly from-the roller track 17 is a flange 22 formingf a splashv guard( Journaled in the end heads lofare shafts 23, 23-a upon whicharefmountedcombined roller and gear elements 24for`co`action withn roller track 17 andy their associated vgears 18. Y These shafts are disposed adj a cent thebottom of the troughs and the elements 24C serve both to support the screen frame and as a driving means therefor, shaft 23 being projected at one end of the trough and associated with a drive generally designated at 25.
Likewise extending longitudinally'of th casing and supported at its ends therefrom is an inlet or distributing pipe 37 the opposite ends of which are open and adapted for communication with feed pipes 38. Distributing pipe 37 is eccentrically disposed with relation to the screen and at the approximate level of the axis thereof and has extending therefrom a plurality of radially directed pipes 39 the end portions of which are ar ranged in close proximity to the adjacent portions of the screen.
Clamped to the distributing pipe 37, as at 4:0, are substantially semi-circular baffles or auxiliary splash guards 4:1. These baffles are disposed immediately inwardly of annular flanges 22 and elfectually cut off any splash which might occur in the lower half of the casing, thus eliminating a tendency of dirty liquids within the screen to mingle with those lying exteriorly thereof.
In operation of the strainer, assuming the apparatus to be driven, the'luid to be strained is admitted simultaneously through pipes 38. This results in an equalization of pressures within the main distributing pipe 37 so that the discharge of the fluid is substantially uniform throughout the Y length of the casing. The auxiliary distrib uting pipes 39 insure delivery of this fluid directly against the screen and at a time immediately after this screen has passed by the spray pipe to drive any material adhering 7 thereto into the trough 30. Foreign matter which cannot pass through the screen will be carried by the screen until it overlies the trough and will be removed therefrom by the spray pipe and deposited in the trough. Due 8 to the fact that this trough has no perforations within the straining zone, line foreign matter which would otherwise have a tend- -ency to collect in the straining zone is carried to the exterior of the machine Where it 8 may be settled out before the fluid is again subjected to a straining action'. Collected trash in thel exposed endof the trough may be removed from time to time as this is found necessary. Due to the sectional formation of 9 the casing cover and to the formation of the screens in removable sections, repairs may be readily made at any time when they become necessary.
The construction being capable of a c0n- 9 siderable range of change and modification without in any manner departing from' the spirit of my invention, I do not wish to be understood as limiting myself to the particular structure herein illustrated except as l hereinafter claimed.
I claim: Y
1.
