Definitions

  • the present invention relates to the manufacture of plaster objects, essentially in the form of a plate, and more specifically to the casting on a pouring floor movable in translation of a mixture of plaster and water contained in a bottomless tank. placed on said casting hearth.
  • the mixture is introduced through the supply tubes with a certain speed, so as to create agitation in the tank and is vibrated the front and rear plates using vibrators mounted on the plates themselves; when reinforcements must be placed inside the products that we manufacture, in some cases we arrange to introduce said reinforcements by rubbing them on the lower edge of one and / or the other of the front plates and rear of the tank.
  • This system is suitable for supplying the forming device from top to bottom with viscous material, but because of its spaced arrangement with respect to the forming sole, because of its need to have identical mats operating in the same way on all the walls. of the hopper, it cannot be used to treat a liquid product which would escape through the space reserved between it and the forming sole, and it cannot itself constitute a pouring device because the idendic belts in vertical movement on all its sides would disturb the flow and prevent the supply of new liquid mixture, in the horizontal direction.
  • the present invention aims to remedy the drawbacks of prior devices.
  • the invention proposes to renew the rear wall of the tank placed on the casting hearth, while maintaining the seal necessary for the treatment of a liquid product, without disturbing the flow or agitation.
  • the invention in a first embodiment, provides a casting device on a casting hearth movable in translation, of a liquid mixture, plaster and water essentially, from a bottomless tank placed on said hearth pouring, containing the mixture to be poured, the side walls of which are formed by endless bands, provided with a pouring slot adjacent to the pouring bottom under the front wall of the tank, device in which the rear wall of the tank is a portion of a flat plate which is flush with the pouring hearth and which is held pressed against the side walls of the tank, having at least a dimension twice that of the rear wall of the tank, mounted slidingly with respect to said tank in a direction such that by sliding, the flat plate portion facing the tank and which acts as the rear wall, can be put out of service and simultaneously replaced by the plate portion which is juxtaposed to it, the out of service portion being cleaned.
  • the invention in a second embodiment proposes a casting device on a casting hearth movable in translation, of a liquid mixture, plaster and water essentially, from a bottomless tank placed on said hearth casting, containing the mixture to be poured, the side walls of which consist of endless bands movable in the same direction and at the same speed as the casting hearth, and provided with a casting slot adjacent to the casting hearth under the front wall of the tank, a device in which the rear wall of the tank is a portion of the side surface of a cylinder in contact with the side walls of the casting tank, flush with the casting bed, said cylinder being rotated so as to to present an ever different portion in contact with the mixture in the tank, the out of service portions being cleaned.
  • the cylinder has a vertical axis, with its side wall in contact with the side walls of the casting tank.
  • the cylinder has its horizontal axis, perpendicular to the direction of translation of the casting hearth, and it is in contact with the side walls of the reservoir through its bases.
  • the surface portion of the cylinder which has come out of contact with the mixture of the reservoir is cleaned by a reinforcement intended to be introduced into the product produced, said reinforcement rubbing against the surface of the cylinder to be cleaned.
  • the invention proposes to give the front plate of the tank a domed shape with horizontal bending axis perpendicular to the direction of advance of the casting hearth , and to introduce a reinforcement inside said tank, pressing on this curved surface to clean it.
  • Figure 1 shows an installation for pouring a liquid mixture based on plaster and water.
  • this mixture may contain other substances such as accelerators or retarders, reinforcing elements such as cut fibers, fillers, surfactants, thinners, resins, foams, etc. ., which will not be mentioned later, it will simply be called a mixture of plaster and water.
  • the casting installation comprises a horizontal casting hearth 1, movable in translation in the direction of arrow F, two lateral strips 2 and 3 each rotating around two rollers 4 and 5 and forming vertical edges at the casting hearth, a front wall 6 in the form of a vertical plate perpendicular to the direction of advancement of the floor 1 and a rear plate 7 parallel to the front wall 6, bearing on the ends of the lateral bands 2 and 3.
  • the rear plate 7 has a length sufficient to form at least two portions 7a and 7b arranged side by side, each capable of forming the rear wall of the casting tank. It is slidably mounted on two vertical slides 8 and 9. Periodically, the plate 7 is slid in these slides so as to deactivate the portion which closed the tank, for example the portion 7a, and to replace it with the other, in this case the portion 7b. The portion 7a is then cleaned and it is ready to be put into service again in place of the portion 7b.
  • the slides are high enough to allow the height positions of the plate 7 to be adjusted.
  • the plate 7 may have its lower edge covered by a bead 10, or may carry a curved flap, directed outside the tank to guide the introduction of a reinforcement in the product that is manufactured.
  • FIG. 2 shows a pouring head of the same type but in which the rear wall of the tank is a cylindrical drum 11 with a vertical axis 12, the diameter of which is equal to the width of the casting sole 1.
  • the axis 12 of this cylinder 11 is arranged so that the front of the cylinder, which acts as the rear wall of the casting tank, rests on the floor 1.
  • the cylinder 11 is in contact with its two generators diametrically opposite with the side bands 2 and 3 and it has a seal 13 on its underside which seals with the casting sole 1.
  • the axis 12 of the cylinder 11 is equipped with a pinion 14 connected by a chain 15 to a motor 16 for the rotary drive.
  • these means are placed so as to act on the portion of cylinder wet with plaster which has just left the reservoir, that is to say near the side shown in the figure when the cylinder rotates in the direction of arrow I.
  • this cylinder is suspended by its axis, and it. can then be entirely located above the movable casting hearth.
  • this advantageous arrangement makes it possible to introduce a reinforcement into the product, near the lower surface, by causing it to arrive under the drum 11.
  • a reinforcement introducer 19 independent, in the form of a horizontal and transverse bar, or curved shutter, will be arranged at the rear of the drum 11.
  • the front plate 6 is surmounted by a vibrator 20 and it is crossed by tubes 21 for supplying the mixture.
  • a vibrator 20 As also explained in this document, the front plate 6 is surmounted by a vibrator 20 and it is crossed by tubes 21 for supplying the mixture.
  • the front wall 6 of the casting tank can be curved so that the energy per unit volume of mixture contained in said tank, supplied by the jets through the supply tubes 21, is substantially the same in the center and on the edges of the tank.
  • the drum 11 is supported on the ends of the side bands 2 and 3 and it is of larger diameter allowing to have a tank of practically rectangular surface, better agitated by the supply jets than the tank previous to two pointed corners, adjacent to the drum.
  • the drums 11 are of thickness substantially equal to the height of the front plate, and at least sufficiently thick to contain the mixture without overflowing. They are mounted on a slide so that their spacing can be adjusted relative to the front plate and is located at such a distance from the latter that the adjustments made in the case of a fixed and flat rear plate are not modified. The explanation of these settings will be given later.
  • the cylinder 11 is rotated, either continuously or discontinuously, at a speed such that a point on its surface in contact with the plaster mixture at a given time either removed from the tank and cleaned by the cleaning means 17 and 18 before the plaster which has deposited there has had time to set, or times of the order of 2 min for a plaster without setting modifier.
  • the curved surface of which a portion forms the rear wall of the casting tank is a cylindrical roller 22 with horizontal axis 23, of length equal to the distance between the side bands 2 and 3 so that the seal between said bands and the cylinder is obtained.
  • the shaft of this cylinder rotates in bearings 24 mounted on a support with two slides 25, one vertical, the other horizontal so as to allow the height adjustment and the adjustment of the distance relative to the front plate.
  • the axis of this roller 22 is connected to a motor 26 capable of driving it in rotation.
  • a sealing shoe 27 having substantially the shape of a prism but the upper surface of which is concave can be placed at the rear of the roller 22.
  • This sealing shoe 27 is mounted on horizontal slides 28 allowing its correct positioning.
  • the roller 22 has a diameter large enough that its axis can pass over the side bands 2 and 3, so as to be supported and driven by the motor 26. A diameter of the order of 30 cm will be common. It may be a roll of cast iron, steel, plastic, etc., preferably a material which is not very porous and hard.
  • the front plate can be given a domed shape with horizontal generatrixes perpendicular to the direction of advance of the casting hearth.
  • this convex shape of the front plate can be envisaged with all the variants of rear wall: flat wall, drum wall with vertical axis or roll wall with horizontal axis .
  • the roll 29 for storing the reinforcement 30 which is introduced inside the tank is disposed in front of the front plate or at least vertically above it so that said reinforcement 30 rubs against the surface of said front plate 6.
  • a ramp 35 independent of the front plate 6.
  • the ramp 35 is a tube of length equal to the width of the casting head, provided with a row of holes 36, connected in the middle of its length, by a tube 37, to the means producing the mixture of plaster and water.
  • This ramp is disposed between the two front and rear plates of the bucket, parallel to said plates, as close as possible to the front plate, is immersed in the mixture so that the jets of mixture which it delivers through orifices 36 are submerged like the jets delivered by the tubes 21 through the front plate in the other embodiments, or placed immediately above the free surface of the liquid, with orifices 36 slightly inclined downwards so that the jets , while rapidly penetrating into the mixture, produce the necessary agitation.
  • the orifices 36 are distributed like the supply tubes 21 which pass through the front plate in the other embodiments.
  • the energies of all the jets exiting the ramp are identical, the sections of the orifices progressively progress from the middle of the ramp towards its ends.
  • the procedure is as follows. First, the height of the roller 22 is adjusted relative to the casting floor 1 by adjusting the position of the bearings 24 on the vertical slides 25. The lower generator of the roller 22 must be at a distance from the casting floor equal to the height at which you want to position the reinforcement in the thickness of the product.
  • the procedure is as if it were a flat and fixed rear plate; that is to say that once the supply flow rate for the mixture is fixed in order to manufacture plate products of a given thickness at the chosen speed of the casting hearth, the number of supply tubes liable to be determined is determined.
  • the cross-section of the feed tubes and pipes is determined upstream so that the speed of the mixture prevents deposits, that is to say greater than 10 cm / s, we create the casting slot under the front plate 6, we adjust the distance from the front plate to the roller or rear drum so as to have, in the casting tank, a stable mixing level and supply jets submerged. Distances between the front plate and the front generator of the roller of the order of 10 cm will frequently be encountered.
  • the reinforcements are then introduced by dispersing their storage rollers so that the reinforcements well sweep the surfaces which they are responsible for cleaning.
  • a reinforcement 31 is passed under the roller 22 and then under the front plate 6.
  • the reinforcement driven by the casting, stretches.
  • the storage roller 32 of the reinforcement 31 is placed so that the reinforcement 31 winds at least a quarter and preferably a third of the rear roller 22.
  • the reinforcement 31 will descend vertically until contact with roller 22.
  • the sealing part 27 will be advanced under the roller 22 to stop this leak. It can be seen that with a roller 22 30 cm in diameter, spaced 6 mm from the casting hearth, under which passes a mat of entangled continuous wires 2.5 mm thick in the free state, with speeds from the 1.50 m to 3 m / min casting bottom, there is no leakage. The leak only appears if the space is increased by 1 or 2 mm.
  • the speed of rotation of the roller 22 or of the drum 11 is then adjusted, so that a point on the roller does not remain in the plaster or covered with plaster without being cleaned for more than a time of the order of 2 min. , corresponding to the time necessary for the plaster to start setting.
  • a mixing height of approximately 15 mm in the tank a peripheral speed between 1 cm / min and 10 cm / min will be suitable, and a speed of the order of 3 cm will be commonly chosen.
  • the rotation speed should not be too high, so as not to disturb the casting. If the rotation is sequential, rotations will be carried out approximately every minute, at an angle such that the constraints already stated are respected.
  • these grids consist of orthogonal wires welded to each other, with all the "warp” wires entirely on one side of the grid midplane, and all the “weft” wires entirely on the other side of this same plane, we will choose to put in contact with the curved front wall those of the wires which will be the most transverse to the direction of travel of said grids, or in other words most parallel to the plane of the casting hearth, to promote cleaning of this wall.
