3 Claims. c1. 22-s9 The preparationoff-oundry moulding materials is general y .cfiectedirfsuch? mannerthat the sand used (old sand) is ,mixednwith fresh sand afternhe coarser components have been sieved-01f and the iron particles separated out,theflmixture being'tsubsequently treated in an edge mill or paingririder; The object of the edge mill or pan grinde'ris' to grind. the fine clay-particles and mix them with the old and the fresh sand, so that a mass is formed WhlChiS SllbSlflIllliillY completely homogeneous.
The known methods operated with an edge mill or pan barrel or 'cylinder having a'n'in'let for the moulding ma-v terial and an outlet or discharge device at the end of the cylinder and also a centrifugal device, advantageously in the form of .an impeller disposed within thecylinder and operating to fling the sand repeatedly against the inner wall of the cylinder from which it falls back. In addition, a guide plateis mounted in the cylinder which imparts an axial feed movementto the moulding material in its path fromone centrifuging stage to the next in the cylinders Such apparatus operates, satisfactorily in the. preparation of moulding-sand. j I
When therequirements are more exacting, the apparatus may be combined with one or several rollers, which extend throghout the greater part of the cylinder and in the direction of the longitudinal axis of thecylinder, thussubjecting the material 'to additional pressure and kneading treatment, so that the crushing and distribution is considerably improved and so that the moulding sand will meet any requirements that may be made.
The cylinder is preferably so constructed as to rotate,
the advantages being that the movement of the sand is aided, a unilateral wear of the cylinder is avoided, and any sand adhering to the inner Walls of the cylinder can be removed by scrapers or the like.
The axial movement of the molding material through the cylinder can be effected by mounting the blades of the impeller at a slight inclination in the cylinder. In the path of the molding material stationary guide means are advantageously provided, which consist of inclined plates which impart an axial movement component to the flying sand passing it to the space between the pressure roller and the cylinder. The roller is provided to rotate above the lowermost position of the interior of the cylinder to leave a space between the roller and cylinder, so that the roller cannot become covered with sand and can operate smoothly. The roller may be mounted 2. so as to be deflec'table or movable, preferably on a rocker arm, which is'provided with reversing devices in the form of weights, springs or the like.
When, for workingthe material several times, several rollers are provided in series, they are so disposed that the roller-gaps decrease progressively in the direction of operation. i i
Two constructions of the apparatus according to the invention are diagrammatically illustratedby way of example in the accompanying drawings:
The more simple construction operating only with an impeller is shown in Figuresl and 2, whereas the apparatus illustrated in igur s" 3:to 5 comprises rollers as well as an impeller orcentrifuge device.
In the drawingsz Figure 1 is a longitudinal section,
Figure 2 is a corresponding.cross section.
Fig. 2A is a sectional plan view taken on the line 2A of Fig. 1.. Y
Figure 3 is a longitudinal section on the line III-III in Figure 4, A
Figure 4 is a cross-section through the middle of the apparatus of Figure 3, and,
Figure 5 is a longitudinal section along the line VV of Figure 4. 5
In the machine according to Figure 1, the sand through the funnel I -passes to the interior or" the cylinder 2, which is mounted to be rotatable on the stationary rollers 4. The cylinder is rotated by a belt 5, which may be driven by an electric motor of any suitable design.
The ends ofthe cylinder are closed by stationary endplates 6 and 7, which may be connected to the cylinder by means of anchor'bolts 8. A centrifugal device is provided in the cylinder and consists of a shaft it on which are mounted blades 11. The shaft 10 extends through the end-plates 6 andq7 and 'is mounted in bearings in the stationary frame 14 at the positions 12 and 13. The shaft 10 is driven through a belt-pulley 15 and an appropriate transmission gear, by a separate motor, or by a drum motor.
Stationary guide means consisting of a plate 249 inclined from the vertical axis and a row of vertical guide plates 21, mounted on this plate in a position, inclined from the longitudinal axis, are also provided in the interior of the cylinder. 1
When the moulding-sand enters the interior of the cylinder through the' feed funnel 1 and through an opening provided in the end plate 6, it is caught by the blades 11 and flung with considerable force against the inner walls of the cylinder 2-, so thatthe-clay-particles are battered,
the various components ofthe sand or of any otherfoundry moulding material being at the same time intimately intermixed. The upwardly flung sand is fed over and over again to the centrifugal device (10, 11) by the guide-means 20, 21, but each time at a different position, as the plates 21 guide the sand in the axial direction, so that it gradually reaches the left-hand end (in the drawing) of the cylinder 2, after having been repeatedly centrifuged, where it is finally discharged from the cylinder by means of a guide-plate 25 or any other suitable discharging device.
The cylinder is provided with scrapers 26 or the like, which may be provided at different convenient positions on the periphery of the cylinder, and which are mounted in known manner so as to be deflectable.
In the construction according to Figures 3 to 5, in addition to the parts above referred to, there are provided rollers 30, 31, and 32, by which the material, fed by the guide means 20, 21 and previously centrifuged, is subjected to further pressing and grinding, so that the nodules of clay in the fresh sand are substantially completely disintegrated, ground and'distributed; In ordinary circum- 3 stances, the roller 30 will be sufiicient. The cylinders 30 to 32 are not driven, being mounted in any appropriate manner for rotation in the frame, either in hearings, or, for example, in rocking levers 35 and36.
The parts referred to with reference to Figures 1 and 2 of the drawings are shown in"Figure 4, 33*being the motor for rotating the cylinder and the centrifugal means, the motor driving the shaft 41 through the belt-drive 40 and through the shaft 41 and the belt 5 driving the cylinder 2,, and through the belt 42 the pulley 15--and thus the centrifugal shaft 10. t
