Definitions
- the invention relates to a mixer with at least one mixing shaft comprising a mixing trough with an approximately cylindrical inner trough surface occupied by wear protection tiles and at least one mixing element lying adjacent to the trough inner surface and rotating around the mixing trough axis with one of the lining organ surfaces approximately formed by the wear protection tiles and following an angle of attack against has a surface line of the lining inner surface which is parallel to the mixer axis and intersects the edge of the mixer organ, the wear protection tiles being arranged in rows which are approximately parallel to the surface line approximately mutually parallel line separating joints between adjacent rows and with individual tile separating joints extending at an angle to the row separating joints are arranged between the individual tiles of each row.
- Such a mixer is known for example from DE-PS 12 37 936.
- the wear protection tiles are generally interchangeable and can be replaced as intended after wear, so that the mixing trough construction is retained.
- Such trough linings are used in particular in compulsory mixers for mixing powdery, granular and plastic mixed materials, for. B. in mixers for processing building material mixtures.
- the wear protection tiles are designed with a rectangular outline, the individual tile separating joints of adjacent rows lying in circumferential alignment with one another.
- the invention has for its object to design a mixer of the type mentioned in such a way that the premature wear of the individual tile separating joints running transverse to the longitudinal direction of the tile lining is largely avoided.
- the individual tile joints are perpendicular to the row joints. If you then additionally ensure that the individual tile separating joints of adjacent rows are offset by half the individual tile dimensions in the row longitudinal direction, you can get by with a single type of compensation pieces, namely compensation pieces whose length in the row longitudinal direction is equal to half the tile length in the row longitudinal direction .
- the individual tile separating joints can also be inclined against the circumferential line of the inner surface of the trough.
- the individual tile separation joints inclined against the circumferential line of successive rows can all be in alignment with one another in the circumferential line direction.
- the individual tile separating joints are inclined against a circumferential line
- an interruption of the line flow along the individual tile separating joints is achieved and, on the other hand, this measure ensures that an inner trough surface can be lined with a single compensating tile in addition to the normal tiles.
- the leveling tile then differs from the normal tiles only in that one of its end edges running transversely to the longitudinal direction of the row runs parallel to the associated circumferential line.
- the wear protection tiles can rest against the inner surface of the trough in an abutment area surrounding an approximately central fastening point and can have a short, approximately constant distance from the inner surface of the trough outside this abutment area.
- This embodiment ensures that when the wear protection tile is fastened, for example by means of a clamping screw, no bending stresses can be introduced into the tile. however, it is possible to support the tiles on the inner surface of the trough.
- the tiles approximately meet with their edge surfaces along the row separating joints on the lining inner surface and form gaps widening towards the inner surface of the trough. In this way, the tiles are left with a certain degree of tumbling and the risk of destruction through mutual imprinting of internal tensions is avoided.
- the tiles on their outer surfaces i. H. those areas that lie against the inner surface of the trough be provided with recesses.
- the double-shaft compulsory mixer shown by way of example in FIG. 1 comprises a double-chamber mixing trough which is composed of two mixing troughs 10.
- a mixing shaft 12 is arranged in each of the two mixing troughs 10.
- the mixing shafts 12 carry in their central axial section mixing elements 14 in the form of mixing blades, which are arranged in such a way that they convey the mix in the two mixing troughs 10 in opposite directions and at the same time move from mixing trough to mixing trough, while at the ends of the two mixing shafts 12 transfer elements 16 are arranged, which ensure that at the ends of the two mixing troughs 10, the material to be mixed is transferred from one mixing trough to the other mixing trough. It is only of interest for the present consideration that the transfer organs 16 have a different angle of attack with respect to the mixing elements 14.
- a mixing trough 10 has a cylindrical inner trough surface 18, which has a circumferential line U and a surface line M.
- the surface line M is parallel to the axis A of the mixing shaft 12.
- the inner trough surface 18 is covered with a tile lining 20.
- the tile lining 20 is formed by wear protection tiles 22.
- the wear protection tiles 22 are arranged in rows of tiles 22A, 22B, etc. It can be seen that the wear protection tiles 22 of the rows 22A and 22B are offset from one another, wherein between the rows 22A, 22B etc. row butt joints 24 are formed parallel to the surface line M and between the individual wear protection tiles 22 of each row of individual tile separating joints 26 are formed.
- the single tile parting lines 26 are in the longitudinal direction, i. H. offset from each other in the generatrix line direction M and measured by half the length of a wear protection tile in the generatrix line direction M.
- the wear protection tiles 22 were arranged such that the individual tile separating joints 26 were aligned with one another, in contrast to the offset arrangement according to FIG. 1.
- the mixing elements 14 are arranged with their mixing element edges 28 at an angle ⁇ against the surface line M.
- the peripheral speed of the edge of the mixer organ is designated v u .
- v u The peripheral speed of the edge of the mixer organ
- v g The resulting speed of the mixed material at the location X of the mixing organ edge 28.
- This resulting speed v r results from vectorial superimposition of the peripheral speed v u and the sliding speed v g , the size of which in turn is dependent on the angle of attack ⁇ and on the coefficient of friction of the material to be mixed along the edge of the mixing element 28.
- This component parallel to the individual tile separating joint 26 of the resulting speed vector v r leads to a pronounced linear movement of the mixed material taking place along the individual tile separating joints 26, which leads to premature wear of the wear protection tiles 22 along the individual tile separating joints 26.
- This linear movement of the mixed material along the individual tile separating joints 26 is all the more pronounced in the known embodiment according to FIG. 2a, since the individual tile separating joints 26 are aligned with one another parallel to the circumferential line U. According to FIG. 2, this leads to wear of the wear protection tiles 22 along the individual tile separating joint 26 between the mutually facing edge surfaces 30 of the wear protection tiles.
- the wear protection tiles 22 are again arranged in rows 22A, 22B, etc., the row separating joints 24 again running parallel to the surface line M.
- the tiles 22 within the individual rows 22A, 22B etc. are now offset by half their length in the direction of the surface line, so that the individual tile parting lines 26 in the direction of the surface line M are mutually offset are offset, as also indicated in Fig. 4.
- the inclination ⁇ of the resulting speed v r compared to the normal N on the single tile butt joint 26 has now remained the same as in the known embodiment according to FIG. 2a.
- the individual tile separating joints 26 are inclined at an angle ⁇ with respect to the circumferential line U, as shown in FIG. 6.
- the pronounced line movement takes place along the individual tile separating joints 26 and the material is pushed essentially vertically over the individual tile separating joint 26 through the mixing organ edge 28. It has been shown that in this way the leveling out along the individual tile separating joint 26 which occurred in the prior art according to FIG. 2 and the resulting damage to the mixing organ edge 28 is further reduced.
- the offset of the individual tiles 22 in the longitudinal direction of the row, ie in the direction of Surface line M is equal to the projection p of a single tile separating joint 26 onto a row separating joint 24.
- compensation tiles 34 are provided, the end edges 36 of which extend transversely to the surface line M and form a 90 ° angle with the surface line. It can also be seen from FIG. 5 that a single type of compensating tile 34 can be used at both ends of the rows 22A, 22B etc.
- the improvement is achieved only by the offset of the individual tile separating joints by the dimension p in the surface line direction M, which is also present here. You then have the advantage that you can get by with a single normal tile and with a single compensation tile. If the individual tile separating joints located in the area of the transfer members 16 are worn out prematurely and thus a loss of service life occurs, the advantage still remains that one can in the larger area of the mixing members 14 (see Fig. 1) the wear protection tiles 22 are maintained longer and thus the extent of the necessary replacement repair remains reduced.
- a normal tile 22 for the embodiment of FIGS. 5 and 6 is shown.
- the angle of the individual tile separating joint 26 against the circumferential line direction U is drawn in with ⁇ and is assumed to be approximately 9 °.
- the normal tile 22 has a projecting central contact surface 38 in the area of a central fastening opening 40 on its rear side. It can also be seen that the normal tile 22 is designed with recesses 42 on the back.
- the compensation tile 34 shown in FIG. 9 is designed accordingly.
- the row parting line 24 is designed as a parallel gap which extends from the inner surface of the tile lining to the inner surface of the cylindrical trough.
- the mounting holes 40 are arranged in the corner points of a rectangular grid.
- compensation tiles are designated by 23 there.
- These compensation tiles 23 have in the row longitudinal direction, i. H. in the surface line direction M half the length as the normal tiles 22.
