Definitions
- the invention relates to a carrier with at least one wear part, in particular wear shoe, for screw presses with a screw helix, wherein the carrier can be fastened to the worm helix.
- the invention relates to a screw press for separating liquid from a pulp suspension with a jacket which has openings for the passage of the liquid, and with a shell-rotating screw with a screw helix, are attached to which carrier with wear parts.
- centrifuges wear parts e.g. from WO 81/02853 or WO 95/24352.
- the centrifugal forces must be considered, whereas in screw presses the pressing forces on the front side and the forces generated by the friction must be considered in the circumferential direction.
- the solution for centrifuges can not be transferred to screw presses.
- the invention is based on the object to provide a carrier with at least one wearing part for screw presses and a screw press, on which carrier are fixed with wear parts available, the wear parts can be very precisely connected to the screw flight and withstand the conditions of use in the high pressure part ,
- the screw press on at least one attached to the screw spiral wear part which is material and positively connected to a carrier.
- This embodiment of the compound of worm gear and wearing part which is very small in relation to the worm helix, can be exposed to very high loads, since the positive connection reliably transmits the forces and ensures the cohesive connection for a sufficient grip.
- the wear part is preferably made of hard metal. Due to the positive connection of the wear part can still be fixed even with poor cohesive connection.
- the cohesive connection is a solder joint, in particular a brazed joint and the positive connection a projection engaging in a recess, wherein in the invention, the projection on the wear part and the recess may be provided on the carrier or vice versa.
- the carrier is a carrier strip to which a plurality of wearing parts are attached, this brings in particular manufacturing advantages, since the connection can be carried out very precisely and the prefabrication of said parts can be realized without much effort.
- the recess has a closed circumference.
- FIG. 1 shows a section through a part of a screw press
- FIG. 2 shows a first embodiment of the wear part according to the invention
- FIG. 3 shows the wear part from FIG. 2 on a screw flight
- FIG. 4 shows a second embodiment of the wear part according to the invention on a screw flight
- FIG Fig. 5 attached to a carrier wear parts.
- Fig. 1 is a detail of a screw press 1 for separating Liquids of pulp suspensions shown.
- the screw press 1 has a jacket 2, which is provided with liquid passages through which liquids pressed out of a pulp suspension can pass out of the screw press 1.
- a worm shaft 3 is arranged, on which a spiral screw 4 is mounted.
- wear parts 6, in particular wear shoes are arranged on the front side of the helix 4 and are fastened to the helix 4 in the region of their radially outer edge.
- the invention can be used essentially in all known screw presses for separating liquids from pulp suspensions, as are known, for example, from the screw press shown in DE 197 15 173 C2.
- FIG. 2 shows a first embodiment of the wearing part 6 according to the invention with a substantially wedge-shaped tapering cross-sectional shape.
- the wear part 6 is arranged on a support 7 which is shown at an angle in an L-shaped manner and connected to it in a material and form-fit manner.
- the wearing part 6 does not run completely pointed, but lies with its thinner end (in Fig.2 below) on the front side of a protruding from the carrier 7 nose.
- Wear part 6 and carrier 7 are in the embodiment of hard metal. For cohesive connection, these parts are brazed together. This also allows parts made of different materials to be well connected.
- the positive connection is made in this embodiment via a arranged on the wear part 6 projection 8, which is formed by a pin and engages in a recess 9 in the carrier 7.
- the projection 8 and the carrier 7 are further connected cohesively to one another in the region of the recess 9 by means of a soldered connection 10.
- the projection 8 and the recess 9 may be of any cross-section, e.g. a round cross-section 9a or a polygonal cross-section 9b (FIG. 5). In the context of the invention, it is only important that these two parts have a corresponding shape.
- the recess 9 is formed with a closed circumference. This also makes it possible to control the forces in the circumferential direction, without the wearing parts come loose and thus lead to damage in the screw press or in the process downstream equipment.
- the projection 8 opposite side of the wear part 6 is designed to wear or wear resistant.
- an additional layer 11 of suitable material may be applied.
- the wearing part 6 can also be made entirely of a wear-resistant material.
- the carrier 7 is located with its angled portion 12 on the screw helix 4 in the region of its radially outer edge.
- FIG. 4 shows an embodiment which is substantially identical to the embodiment shown in FIG. One difference, however, lies in the fact that the projection 8 on the carrier 7 and the recess 9 in the wear part 6 are arranged.
- the projection 8 may be a pin as described for Fig. 2.
- the projection 8 arranged on the carrier 7 is formed by a strip which extends parallel to the spiral screw 4.
- the carrier 7 may be a carrier strip.
- a plurality of wear parts 6 may be disposed adjacent to the support bar. Wear parts 6 can each be connected in a form-fitting manner to the carrier 7 via a respective pin or can be connected together via the e.g. through the strip (as described for Fig. 4) formed projection 8th
- the use of the carrier 7 according to the invention is not limited to the examples shown or explained.
- the carrier 7 can be welded to the helix 4 as well as e.g. to be bolted to her.
- a screw press 1 for separating liquid from a pulp suspension has a jacket 2, which has openings for the passage of the liquid.
- the shell 2 is a screw with a screw spiral 4, on which wearing parts 6 are fixed, rotatably mounted.
- Wear part 6 and carrier 7 are by means of a solder connection cohesively and by means of a arranged on one of the two parts of projection 8, which engages in a recess 9 arranged on the other part, positively connected to each other.
