Definitions

  • the invention relates to a mixer-transport apparatus for floor mortar and the like, comprising a mixing tank having a filling hole that can be sealed, a transport hose being connected to the mixing tank for pneumatic transportation of an earth-humid sand-cement mixture to a site where it is used.
  • mixer-transport apparatuses are known from practice and are described in a brochure of Bredel Machine- en Constructiebedrijf B.V. These known mixer-transport apparatuses are designed as trailers, which can be connected to the rear of vehicles for transportation.
  • the mixing tank that is part of the apparatus typically has a volume of 220 l. In some manner or other the mixing tank is filled with sand and mortar in the proper proportions, after which these components are mixed and, using a compressor forming part of the apparatus, pneumatically transported via a hose connected to the mixing tank to, for instance, a construction site where cement floors are to be constructed.
  • Pneumatic transport requires high pressure, typically amounting to 7-8 atmospheres gauge pressure, and such pressure requires that the sealing of the filling hole in the mixing tank meets high standards.
  • the mixing tank is provided with one connecting stub, elliptic in cross-section, with an edge pointing inward, in which a cover, also of elliptic configuration, is disposed in such a way that the cover is pressed against the inwardly pointing edge of the connecting stub owing to the pressure obtaining in the mixing tank.
  • a cover also of elliptic configuration
  • the present invention aims to overcome these disadvantages and to that effect is characterized by the features defined in claim 1.
  • valve can be displaced in a horizontal plane, it can be moved fully out of the path of the material charged to the mixing tank when it is being filled, so that no sticky mortar mixture will form on the surface of the valve, which would prevent a proper sealing during the pneumatic transport of the material from the mixing tank. Because the valve is flat and its control mechanism is also disposed in a horizontal plane, the construction height of the mixing tank can be reduced by about 25 cm, so that placing the mixer-transport apparatus under existing sand-cement silos no longer presents any problems whatsoever.
  • the vertical movement of the vertical valve shaft over an adjustable distance permits the valve to be pressed in sealing engagement against the 0-ring under the influence of pressurized air introduced into the mixing tank for the pneumatic transportation of its content. After the air pressure is released the valve is pushed in its lowermost position and can be displaced horizontally without pressing against the sealing 0-ring, thus increasing the life span thereof.
  • a sealing ring Disposed around the filling opening is a sealing ring.
  • the opening may be closed by a convex shaped valve which is pivotable about an inclined axle. When swivelling the valve it is wiped clean by the sealing ring, which is pressed against the convex valve surface.
  • the valve is not vertically movable over an adjustable distance between a pivoting and a sealing position.
  • Fig. 1 shows a known per se silo 1 comprising separate compartments for sand and cement and provided with a cement dosaging screw 2 and a sand dosaging screw 3.
  • the mixing and transport apparatus 4 comprises a mixing tank 5, at the top of which a filling hole with a valve 6 is provided.
  • the valve is a coned valve, as described in NL-A-88.02924.
  • the mixing and transport apparatus 4 has its valve 6 placed under the outlet opening of the sand dosaging screw 3 of the silo 1.
  • Figs 2 and 3 show in detail the upper part of the mixing tank 5 with the valve 6.
  • a connecting stub 11 is arranged, which is covered at the top by an upper plate 12.
  • a circular opening 13 is provided in which a ring 14, L-shaped in cross-section, is mounted, the ring being secured to the upper plate 12 by means of bolts.
  • the ring 14 comprises an inlet funnel 15 (shown in part).
  • the ring 14 bounds a circular filling hole 18.
  • a groove 16 is provided for accommodating an O-ring 17, which projects some distance downwards from the bottom surface of the ring 14 and engages the upper surface of a valve plate 23.
  • a vertical bearing bush 19 is mounted on the upper plate 12 and welded to it.
  • the bearing bush 19 accommodates the thickened guiding part 31 of a vertical valve shaft 20 whose lower end projects into stub 11.
  • a bush 22 mounted onto this free end of the valve shaft 20 is a bush 22 comprising an arm 21 extending radially, onto which the horizontal valve plate 23 is mounted. In the position shown in Fig. 2 the valve plate 23, under the influence of the pressure obtaining within the mixing tank, is pressed into sealing engagement with O-ring 17.
  • valve shaft 20 Provided at the top of the valve shaft 20 is a threaded part 24, onto which an adjusting nut 25 and a locking nut 26 are mounted.
  • the bottom surface of the adjusting nut 25 is at a distance X from the upper edge of bearing bush 19.
  • the distance or clearance X determines the distance over which the valve shaft 20, and hence also the valve plate 23, can lower in vertical direction when the pressure in the mixing tank 5 is released.
  • the valve shaft 20 is then pressed down vertically by means of Belleville washers 27, arranged between the bottom edge of the bearing bush 19 and the upper edge of the bush 22 mounted on the valve shaft 20.
  • a plain bearing 28 is mounted, for instance glued, on the upper edge of the bearing bush.
  • a recess 29 is provided for applying a spanner for adjusting the clearance X such that when the pressure in the mixing tank is removed, the valve plate will be just clear of the O-ring 17, so that when the valve plate 23 is displaced horizontally no friction, which causes wear, will be exerted on the O-ring 17.
  • a control arm 30 which, using an automatically operable air cylinder, can be pivoted into a position in which the filling hole 18 is completely sealed, or a position in which the filling hole 18 is cleared entirely, as shown in top plan view in Fig. 3.
  • a grease nipple 34 is provided in the wall of the bush bearing 19, and the guiding part 31 of the valve shaft 20 at its bottom surface is sealed in axial direction by means of an O-ring 33.
