Definitions

  • the invention relates to a foundry mixing machine for preparing a mixture of sand and an admixture, said machine having an inlet for the sand, followed by an annular slot for the sand, followed again by an annular admixing space and furthermore, disposed on said annular admixing space, a feeding device for the admixture, leading into the admixing space, and an outlet for the mixture.
  • a moulding sand mixture which is prepared in a mixing machine of this kind for example from a sand and a liquid, organic admixture having at least two components, viz a binder and a hardener, is used in foundries for making precision moulds.
  • the foundry mixing machines which were previously known are relatively big, stationary units from which the mixture has to be conveyed specially to the place where it will be used in the moulding bay of the foundry.
  • Another known foundry mixing machine U.S. Pat. No. 3,773,299
  • the feeding device has a centrifuge and because of the high speed of the centrifuge there is-a risk of spontaneous combustion of the liquid, organic admixture and possibly its explosion.
  • the known mixing units require several operators.
  • the previous mixing machines also become clogged up in the course of time owing to adhesion of the sticky moulding sand mixture.
  • the problem underlying the invention is to obviate the above-described disadvantages and to provide a foundry mixing machine which is smaller than the conventional ones, free from trouble and can be used without risk with only a few operators in the moulding bay of a foundry.
  • This problem is solved according to the invention, on a foundry mixing machine of the type mentioned initially, through the fact that there are disposed between the admixing space and the outlet two bodies of revolution which are rotatable relative to one another, between which a ring-shaped intermediate space is left open for the mixture, and that in this intermediate space on the walls of the bodies of revolution there is a projection towards the intermediate space provided in each case, the projection of one body of revolution and that of the other overlapping one another in the direction perpendicular to the walls of the bodies of revolution.
  • the projections are solid annular walls and, furthermore, if the projections have, on the mixture inflow side, a surface ascending from the wall of the body of rotation in the direction of throughflow of the mixture.
  • the foundry mixing machine can be operated by one person only, if a separate stock bin is provided for the sand and for the admixture and a supply line is provided which can be put under pressure, the supply line being fitted with a pilot valve in each case, and if a switching device is provided for switching on the driving motor for the body of revolution and, when the operating speed of the driving motor and the pressure in the supply line has been reached, for opening the pilot valves and also for closing the pilot valves and then switching off the driving motor. Simplification of operation is achieved, moreover, by means of an arm which is mounted so as to swivel relative to the housing of the foundry mixing machine and which in turn is mounted so as to

  • the projections 13 of one body of revolution 9 and the projections 13 of the other body of revolution 8 overlap one another in the direction perpendicular to the walls 11 and 12, thus producing a zig-zag path through the intermediate space 10 for the mixture.
  • the intermediate space 10 lies substantially in the plane of the annular admixing space 3.
  • the feeding device for the admixture with pipes 5 and 6 for the individual components of the admixture, is located in the middle of the moulding sand mixer and opens out into the middle of the annular admixing space 3.

  • the compressed air line 60 opens out outside the outlet openings of the pipes 5 and 6.
  • the compressed air line to conduct the compressed air into the pipe for the admixture material in the vicinity of its outlet opening. It might also be conceivable that the introduction of the admixture material was carried out in the radial direction from the exterior into the admixing space 3.
  • the outlet opening of the compressed air line is provided with a nozzle 62.
  • the compressed air line 60 is connected to a source of compressed air not shown and provided with a shut -off valve 61. This valve 61 can be operated by remote control.

  • the outlet openings of the pipes 5 and 6 for the components of the admixture are directed against the cylindrical wall of the ring chamber 63.
  • the air vortex produced in the ring chamber 63 thoroughly mixes the components of the admixture and this mixture flows very energetically into the admixing space 3 where the sand is completely saturated with the mixture of air and admixture material.

  • a clearance such as that marked is left open in the direction perpendicular to the wall 11 and 12 and is always just sufficient for the passage of. the mixture.
  • the intermixing of the mixture in the intermediate space is effected by acceleration at the rotating body of revolution 9, slinging along the ascending wall 14, retardation at the projection 13 of the body of revolution 8, slipping on to the body of revolution 9 from the wall 14' and so on.
  • the mixing machine is provided with the means of mobile suspension, with eyes 16 for example.

  • the valve part 19 can be slid axially to the bell-shaped screen 18 as far as a saddle surface 21 on the screen. The sliding of the valve part 19 is effected by means of screws 20, for example.
  • the body of revolution 9 can be rotated by means of an electric motor 22.
  • the electric motor runs at approximately 1300 r.p.m. so that there is no risk as regards spontaneous combustion or explosion of the admixture material.
  • the electric motor 22 is suspended on a carrier 23 which is connected with the non-rotating body of revolution 8 by way of a pin 24 and a wall 25.
  • the wall 25 and a funnel-shaped part 28 serve to conduct the mixture from the intermediate space 10 to the outlet 7.
  • the inlet 1 for the sand is provided with a flexible pipe part 26 and a slide valve 27 and is connected to a sandstock bin, which is not shown.
  • the bodies of revolution 8 and 9 are constructed essentially of a non-magnetic material and the elements 8 and 9 which carry the bodies of revolution 8 and 9 of magnetic material. Rigidly built into the bodies of revolution are permanent magnets 8 and 9 respectively, the magnetic force of which holds the bodies of revolution to the supporting elements. The connection is secured from twisting by means of a pin 8 or a flute 9

  • These two parts of the mixing machine are capable of being folded relative to one another by means of a hinge 31.
  • the folding of the two parts together and apart round the axis of the hinge 31 of the mixing machine is effected by means of a servo arrangement which has the reference 32.
  • the intermediate space is opened by swinging the two parts of the foundry mixing machine open and removing the bodies of revolution 8 and 9, which are preferably constructed from a light synthetic material, from the elements 8 and 9 which carry them and cleaning them or replacing them by spare parts from stock, after which the two parts of the mixing machine are swung back again and the machine is ready for use again, all this being achieved without any diffuclt dismantling operations.
  • a foundry mixing machine may also be constructed so as to be divisible in three parts. That is to say a first part, which is essentially an inlet 1 for the sand, a second part, which is the first body of revolution 8 following the inlet 1, and a third part which is essentially an outlet 28 for the sand and which also has the second body of revolution 9 and its driving motor.
  • a clamping arrangement 33, 34, 35 The clamping arrangement has a first yoke 33 which is connected to a first mixing machine part, viz the inlet 1, and a second yoke 35 which is connected to the third part of the mixing machine, viz the outlet 28.

  • the body of revolution 8 has no magnet. Removal of the first body of revolution 8 renders the other body of revolution 9 freely accessible so that it can be taken away simply by overcoming the magnetic force holding it to the supporting element. The cleaned bodies of revolution 8 and 9 are then replaced in position, the mixing machine is closed by returning the second yoke 35 by means of the servomotors 34 and the unit is then ready for service once again.
