MACHINE FOR MIXING TWO on MORE SUBSTANCES WITH EACH OTHER Filed Nov. 9', 1927 Patented Dec. 17, 1929 PATENT OFFICE HJALMAR ERIKSSON, OF SKOLDINGE, SWEDEN MACHINE FOR MIXING- TW'O OR MORE SUBSTANCES WITH EACH OTHER Application filed November 9, 1827, Serial This invention relates to a machine for mixing two or more substances with each other, for instance ore concentrate or the like, with coal or coke breeze for the purpose of either rendering the mixture fit for the sintering process or for turning it into pieces or the like.
The mixing devices used hitherto for pre paring the respective substances for the sintering procedure suffer from the drawback that the mixing is not thorough enough. It occurs frequently that the clods or clogs contained in the raw material or materials, for instance in iron ore concentrates, leave- 1 the mixing device in the same state in which they have been introduced into it. Thorough mixing is, however, very important, and decisive for the result, especially for the sintering procedure, if this is to proceed properly and uniformly. The object of the present machine is to bring about this result, and is attained by means of a drum, preferably a vertical drum, which receives the substances to be mixed and through which extend rods arranged crosswise with respect to, and in several distances from each other. An axle arranged in said drum is provided with arms located in the spaces between the superposed rods. These latter which can be moved together with the drum, and the arms which can be stationary in that they are attached to said axle co-operate and effect a very thorough and intimate mixing of the respective substances. Glods or clogs or the like are completely reduced to very fine particles, the more, as it is possible to work the substances in the machine as long as desired, in that the drum can be rotated as long as required to attain the result aimed at, which is not possible with the existing uninterruptedly working machines, in which the materials remain in the drum a period of time of predetermined length.
The invention is illustrated diagrammatically and by way of example on the ac companying drawing on which Figure 1 is a vertical axial section through a constructional form of a machine designed according to this invention, and Figure 2 is a plan of the same.
No. 232,163, and in Sweden June 16, 1927.
On the drawing, 1 denotes a vertical cylindrical drum carried by means of a ball bearing comprising a bevel-ring 52 secured to the drum, balls 3 and a race-ring 5 which is car ied by vertical standards 4: of U-iron by the intermediary of brackets 45. The bevel-ring 2 meshes with a bevel-wheel 6 ai'hxed to a short horizontal shaft 7 provided at its outer end with a pulley 8. The bearing 7 supporting these members is carried by one pair of the standards 4. It is obvious that the drum 1 can be rotated as long as desired.
9 denotes a ring aliixed to the drum 1 above the gear members 2 and 6 and protecting them from being covered with particles of the materials thrown into the. drum.
The pairs of standards a extend upwardly from a base 10. The position of the drum with respect to this base is such that its lower edge ls'nearly in contact with the surface of the spine. Below the drum a discharge opening 11 is provided in the top plate of the base 10, and the free sectional area of this opening can be varied by means of two slides 12.
The standards 4 are connected with each other at their upper ends by two girders 16 connected with each other by a member 17 serving as upper hold for a vertical .rod 13 of square section, the lower end of which is supported on the base 10. This rod carries arm-crosses 14, of which there may be only two, as in the drawing, or more, corresponding to the size of the machine. The arms co-operate with pairs of rods 15 supported in the wall of the drum 1 and arranged in pairs which cross one another and are, besides, superposed. Each armcross is located between two upper pairs of rods 15 and two lower pairs of these rods. I Wish it, however, to be understood that the drawing shows merely one example of the several possibilities regarding the arrangement and the number of the rods 15, there being only the one presupposition that the centre of the drum remains free in order to provide for the space necessary for the rod 13.
The substances to be treated and mixed are introduced into the drum from above, and their amount is so chosen that also the uppermost pair of rods 15 is covered with them.
The substances are mixed with each other by turning the drum with its rods 15 by means of the gearing 8, 7, 6, 2, and the turning is continued until a perfectly satisfying mixture has been produced which can be ascertained by specimens taken through the opening 11. The finished mixture is withdrawn through this opening by and by, and a corresponding amount of fresh substances to be mixed is replenished into the drum from above. The operation can, thus, be carried through continuously, but every charge can be worked as long as desired until the quality of the product is that desired.
I wish it also to be understood that the machine may be reversed in this Way that the drum 1 with its transverse rods 15 is stationary, and the vertical rod 18 is replaced by a vertical shaft also provided with armcrosses 14. It is, furthermore, possible to combine the two constructional forms that is to say, the drum can be rotatory and the arm-crosses as well, and means may be provided for rotating the drum and the armcrosses in opposite directions.
I claim:
1. A mixing machine, comprising, in combination, a revoluble drum, sets of rods traversing said drum at some distance from its longitudinal axis and being affixed to the Wall of said drum, sets of radially extending rods located in planes between the planes of said first-mentioned rods, a centrally arranged stationary holder for said radially extending rods, and means for causing said drum to revolve.
2. A mixing machine, comprising, in combination, a revoluble drum, sets of rods traversing said drum in different horizontal planes and at some distance from its vertical axis, said rods being aflixed to the wall of said drum, sets of radially extending rods located in planes between the planes of said first-mentioned rods, a centrally arranged stationary holder for said radially extending rods, means for causing said drum to revolve, and a stationary bottom for said-drum and having an excentrically disposed discharging opening.
In testimony whereof I afiix my signature.
HJALMAR ERIKSSON.
