Definitions

  • the present invention relates to a wear-resistant lining for a building material trough mixer according to the preamble of patent claim 1.
  • a first food for thought regarding a new, screwless wear plate attachment can be found in DD-PS 41 453.
  • the wear plates are placed on the inner wall of the trough and braced against one another in the manner of a support arch.
  • the axially parallel wear plate edges butt against one another and it is readily apparent that there is a risk that the material moving over these axially parallel abutting edges may lift off the wear plates in the event of unevenness.
  • the object on which the present invention is based is to provide a wear-resistant building material trough mixer lining of the generic type which, on the one hand, can be fastened without screw holes and, on the other hand, is “interlocked” with one another when viewed in the direction of movement of the material to be mixed.
  • the solution to the problem outlined above assumes that the wear plates resting on the inner wall of the mixing trough are clamped in the manner of a support arch (quasi self-supporting), the wear plates each having a pair of complementary convex edges along their edges parallel to the trough mixer. Have concave wedge-shaped tongue and groove-like shape (see claim 1).
  • the essence of the present invention consists in realizing the lining of a building material trough mixer by means of simply placed wear plates which mutually hold and support each other via a complementary latching arrangement and which connect seamlessly to one another.
  • the mixing trough 1 is a cylindrical body, the inner wall 2 of which is covered with wear plates 3. These wear plates 3 are bent in accordance with the curvature of the inner wall 2, so that they lie flat against it. Basically, it does not matter whether the wear plates 3, as shown in the drawing, are arranged like a checkerboard, or whether they are offset from one another in the circumferential direction, for example, with a predetermined pitch. This description of the wear-resistant lining is equally applicable to prior art building material mixing troughs.
  • the present invention relates to the attachment or fixation of the wear plates 3 in the mixing trough 1. It can be assumed that the wear plates 3 each have a pair of convex-concave complementary wedge-shaped tongue and groove on their edges lying parallel to the axis of the mixing trough 1 -have a similar design 4.
  • the wear plates 3 are - as viewed circumferentially - attached to one another so that they rest and rest on the inner wall 2 of the mixing trough 1 in a quasi-self-supporting manner.
  • the shape 4 is designed so that a bias in the radial direction is generated when the wear plates 3 are braced.
  • the mentioned bracing is achieved in accordance with the illustrated embodiment in that a clamping bar 6, 7 is provided parallel to the edges of the filling opening 5 of the mixing trough 1, one of which - compare clamping bar 6 - has a concave edge 8, and the other - compare Tension bar 7 - has a convex edge 9.
  • the edge configurations mentioned correspond to the convex-concave groove / tongue-like shape 4.
  • edges of the circumferential direction which are of the type disclosed in DD-PS 41 453, can also have a convex-concave, complementary wedge-shaped tongue and groove shape .
  • FIG. 2 Another (second) exemplary embodiment of a wear-resistant lining is explained with reference to FIG. 2.
  • each wear plate 3', 3 '' is identical on both edges. Viewed in the circumferential direction, a wear plate 3 'with two convex edges 4' and a wear plate 3 '' with two concave edges 4 '' are mounted one after the other.
