Definitions

  • This invention relates to a centrifugal apparatus and particularly to a discharger mechanism for removing material from gyratory centrifugal baskets of the type used in sugar mill operation.
  • Sugar centrifugals conventionally have a rotating basket and a discharger shoe which can be inserted into said basket so as to operate with a plowing action to cut the sugar from the basket wall, the tip of the discharger shoe entering a revolving layer of sugar on the basket wall and separating the sugar from said wall.
  • a Well-known discharger is shown in the patent to Roberts, No. 2,076,516.
  • One of the objects of the present invention is to provide a centrifugal discharger apparatus which will allow installation of the centrifugal in a space having less height or headroom than previously has been possible.
  • Another object of the invention is to provide a superior control of the angular position of the discharger shoe both when in discharging position and when in a raised inoperative position.
  • a further object of the invention is to provide an improved discharger shaft guide bracket arrangement including easily adjustable bearing surfaces.
  • One of the features of, the invention is to arrange the discharger shaft and guide therefor so that the discharger shoe can be raised above the lower face of the shaft guide and thereafter the shoe swung over the top of the casing.
  • Another feature of the invention is the use of a compound motion handle for moving and positioning the discharger shoe ina horizontal plane or a plane transverse to the vertical axis of the centrifugal.
  • the handle is rotatable in said horizontal plane for moving the discharger shoe relative to said vertical axis, and then the handle and a stop are movable relative to each other in a plane angularly disposed to said horizontal plane for holding said handle and shoe in a predetermined angular horizontal position.
  • the stop or recess with which the handle engages in said positioning or latching operation can be made readily adjustable so that the depth of the first cut of the discharger shoe can be varied as desired when the shoe is in a lowered position.
  • the same stop or recess also can be used for holding the shoe in an inoperative position after the shoe has been raised out of the basket and swung over the curb.
  • a second adjustable stop can be provided to limit the second cut of the discharger shoe after the handle has been disengaged from said first-mentioned stop and the handle rotated to move the shoe toward the basket wall thereby protecting the basket.
  • Another feature of the invention is the pivotal mounting of the shaft guide housing on the curb of the centrifugal or other suitable place with the center or axis of the discharger shaft offset from the center of said pivot, the shaft being non-rotatably mounted relative to the guide. In this manner, pivoting of the guide housing will control the position of the shoe relative to the basket wall and the vertical axis of the centrifugal.
  • the center of rotation of the discharger assembly can be located relative to the line of force of the sugar in the basket against the tip of the discharger shoe, so that the force tends only slightly to assist the shoe in digging into the sugar and so that most of the force of the rotating material is spent against a fixed pivot pin which supports the assembly.
  • Still another feature of the invention is the provision of readily adjustable liners or bearings in the shaft guide so that the clearance between the shaft and guide walls can be initially carefully set and then adjusted as the parts wear.
  • Fig. l is an elevation, partially in section, showing the discharger assembled with the centrifugal basket and curb.
  • FIG. 2 is an enlarged fragmentary view taken along line 2-2 of Fig. 1.
  • Fig. 3 is an enlarged sectional view of the discharger shaft guide taken along line 3-3 of Fig. 2.
  • Fig. 4 is a fragmentary enlarged plan view of a portion of the apparatus of Fig. 1.
  • Fig. 5 is a fragmentary enlarged sectional view taken along the line 55 of Fig. 4.
  • Fig. 6 is a detailed sectional view taken along line 6-5 of Fig. 4.
  • Fig. 7 is a fragmentary plan view, partially in section, of a modified form of the apparatus.
  • Fig. 8 is an enlarged fragmentary view looking in the direction 8--9 of Fig. 7 showing the guide housing positioning means.
  • Fig. 9 is a fragmentary plan view of another modification of the invention.
  • Fig. 10 is a fragmentary sectional elevation of the device of Fig. 9 in the direction
  • a conventional centrifugal basket i0 is suspended on gyratory basket spindle H, a casing or curb l2 being provided in the usual manner for col- I lecting centr'ifugally expelled liquid from basket 13.
  • the discharger mechanism is indicated generally at 13, having a discharger shaft guide housing l4 pivotally carried by stub shaft l5, stub shaft l5 being carried by arm [6 and base [1 of bracket [8.
  • Discharger shaft [9 is vertically slidable in guide passage 29 of shaft guide housing H.
  • the discharger shaft is can comprise a dovetail shaped portion 22 and a second dove-tail shaped portion 23 projecting laterally from the first dove-tail shaped portion. Said second portion 23 extends outside of the guide passage 29 of the discharger shaft guide housing I4 through the longitudinally or vertically extending slot defined by the outer edges 28' and 39 (Fig. 3) of guide passage liners 28 and 39, respectively.
  • the second dove-tail shaped portion 23 may have rack teeth 24 cut in one side thereof, said rack teeth being engageable by pinion 25 which is operabl by handwheel 26 for the purpose of raising and lowering the discharger shaft.
  • Handwheel shaft 26' is journalled in discharger shaft guide housing l4 and a spring 35 may cooperate with the wheel to counterbalance the weight of the shoe and shaft.
  • the discharger shoe 2'! is mounted in some suitable manner on the laterally extending portion 23 of the discharger shaft l9 so that the shoe may be raised above the bottom surface 41 of shaft guide housing 14.
  • the discharger shoe 2'! may be of conventional design as shown, for example, in the aforementioned patent to Roberts, No. 2,076,516.
  • the shoe may take the form shown in Fig.
  • a tip 21a pivoted on a vertical axis to the forward end of the shoe body has a rearward extension 2112 yieldably positioned by a leaf spring 50, and the leaf spring is mounted on the shoe body by a plate 5i which is positioned so as to assist in preventing the shoe from digging too far into solids in the basket during the outward shoe movement.
  • Spring 50 normally holds the tip extension 21?) in engagement with an abutment 210, with the tip 21a positioned as seen in Fig. 4, but the tip is movable inward from that position against the tension of the spring in the event of the shoe being moved so far outward as to press the tip against the basket screen.
  • guide passage 20 has hard surface liners 28 and 29 on two sides of the dove-tail shaped portion of the guide passage, the other wall of the dove-tail shaped guide being formed by adjustable liner 39, said liner being adjustable so as to regulate the clearance between the guide passage and the discharger shaft (9, through a shim or shims 30a and adjusting screws or bolts 3
  • Adjusting bolt 32 passes through a slightly enlarged hole in liner 3D in a direction normal to the wall Ma of the guide.
  • is screw threadedly engaged in guide M in a direction substantially parallel to the face of liner 29, passing through an enlarged hole in liner 30, the head engaging beveled surfac 3
  • may be tightened to position the liner 3!] in the desired longitudinal location relative to wall [4a where the forward end 33' of 39 holds shaft IS with the desired pressure against the face of liner 28.
  • Bolt 32 then may be tightened to lock the assembly and create the desired pressure of the shaft against the face of liner 29.
  • pressure of the shaft against liner 29 may be adjusted.
  • the liner 33 can be adjusted in two directions for regulating the fit of the discharger shaft 19 in the guide passage 20.
  • a stop plate 33 is mounted on the top of the discharger shaft I9, the lateral extension of said stop beyond the discharger shaft cooperating with the top surface 34 of the shaft guide housing I4 to limit downward movement of the shaft and shoe in the basket.
  • the discharger shaft guide housing [4 has operating arm 3% fastened thereto at 35, said arm cooperating with arm positioning bracket 31 and having at its end handle 36a. Movement of handle 36a will pivotally swing discharger shaft guide housing it about stub shaft l5 so as to change the angular position of the discharger shoe relative to the side of the basket [0 when the discharger shaft and shoe are in operative or lowered position, and also to swing the shoe over the curb when the shoe is in its upper position where it is high enough to clear the top 46 of the curb.
  • handle 36a When it is desired to move the lowered shoe to a position closer to the basket wall as material is scraped from the basket, handle 36a may be lifted upwardly, there being sufficient resilience in said arm 33 to allow such movement, and then moved clockwise (Fig. 4) to the position shown in broken lines at 42 (Fig. 6), the arm then resting on top of stop screw 39 and the shoe tip being neat to the basket side wall as seen in the broken lines farthest from shaft l I in Fig. 4.
  • shaft guide housing stop screw 53 carrying lock nut 44 is screw threadedly engaged in shaft guide housing 54, said screw being cooperable with the surface 5 of the arm positioning bracket 3'! so as to limit the movement of the discharger shoe toward the wall of the basket as the handle is swung in a clockwise direction to the broken line position 42.
  • the handle When it is desired to raise the discharger shoe out of the basket and move it over curb H to an inoperative position, the handle is moved counterclockwise (Fig. until the shoe is in a position wherein it will clear the inner edges of the basket top and curb top as handwheel 2?; is turned to raise the shaft it and discharger shoe upwardly out of the basket.
  • handle 3601. again may be moved clockwise until arm 36 is in position to drop into place in recess 38, thus latching the shoe in an inoperative position over the curb.
  • a clearance cut 48 is provided in the top of the curb so that the bottom 41 of shaft guide housing i l adjacent the guide passage may c be swung without interfering with the curb as the shoe is swung over the curb, the shoe being above the lower face ll of the shaft guide housing in the form shown in Figs. 1 to 5, inclusive, and
  • the shoe is latched in its inoperative position over the curb and cannot be accidentally displaced.
  • Discharger shaft 51 may be made of two strips of some suitable metal, such as stainless steel, welded together in the triangular form shown. Strip 59 is formed into an angle constituting two faces of the shaft with the third face 6! welded to angle at 6!.
  • a discharger shoe B2 is: mounted adjacent the lower end of discharger shaft El.
  • Dis-charger shaft bl is vertically slidable in the guide passage defined between surface 63a and adjustable wedge block 63b, there being a passage or slot between the outer edges of said surface 63d and block 632) communicating with the guide passage.
  • Block 631) may be adjustable by means of a series of vertically arranged adjusting screws E i and locked in place by. lock screws 55.
  • arm-66 In order to pivot the guide shaft housing 52 to move the shoe in a plane transverse .to the vertical axis of the centrifugal, arm-66 is mounted on guide shaft housing 52.
  • Adjustable stop screw 61 carried on the guide housing 52 serves to. limit the angular movement ofthe discharger housing is limited at a predetermined position v by contact of the stop screw 61 with the outer face of nose 12 of the pivoted stop arm.
  • the left-hand end of stop arm 68 can be depressed so as to raise nose [2 upwardly.
  • Arm 66 can then be swung to move the guide housing until adjustable stop screw 61 contacts surface 72a of base 54, so a to permit the discharger shoe to take its final cutting position relative to and closely adjacent the basket wall.
  • FIG. 9 Still another form of the invention is shown in Figs. 9 and 10 wherein the discharger shaft guide housing 13 is pivotally mounted at 14 on bracket '35 carried by the centrifugal curb.
