Definitions
- the invention relates to a sidewall armor for lining a side wall of a shredder for sheets, automobiles and the like, a shredder and a rotor for a shredder.
- the invention relates to a shredder in the form of a hammer mill.
- a hammer mill is known, for example, from US 4,009,836.
- a rotor with impact tools runs in a housing.
- the rotor is mounted on a shaft which is usually perpendicular to an insertion direction in the shredder.
- the housing has two side walls.
- the object of the invention is to provide improved systems. [06] According to a first aspect of the invention, this object solves a sidewall armor for lining a side wall of a shredder for sheets, motor vehicles and the like with a cross-sectionally L-shaped corner armor region.
- armor plates are common on the insides of the housing walls in the area of the percussion tools around the rotor and are increasingly used because of the longer possible operating time of a system.
- the side wall panels cover the housing wall along the circular course laterally of the working space around the rotor.
- the side wall of the plant housing springs back outwards.
- the side walls define a working space and this should not open in a slot next to the rotor if possible. Therefore, the side walls are usually designed so that they are aligned approximately with the front-side rotor edge or would preferably meet even in their extension to the rotor, so that the rotor edge is slightly outside of the work space defined by the side walls.
- the jump of the side wall is very close to the rotor, so as not to allow the shredded material as far as possible to take the path laterally past the striking tools of the rotor and to the bearing shaft of the rotor. It is understood, however, that a lot of shredded material hits the housing at this point, ie on the jump of the side wall approximately at the height of the rotor shell surface. This causes a heavy wear.
- the L-shaped corner armor provides a remedy: Due to its shape in addition to the armored side wall now also the Versprung be armored. In the hitherto encountered at this point welds between the protruding under the side wall armor end of the side wall and an outwardly leading square were regularly seen signs of wear. This is not only a danger for the plant as such, but also for operating personnel who go into the plant, for example, to inspect or repair it.
- the side wall armor preferably has an arc segment. It is understood that the lateral surface of the rotor extends arcuately, in a circular arc around the bearing and rotational axis of the rotor. It is therefore advantageous to perform the armor also arcuate.
- the jump in the side wall also extend arcuately, and also as a circular arc segment around the shaft of the rotor. If the sides wall armor in addition to the L-shape in cross section has an arc segment, wherein preferably the cross section along a radial section is present, such a course of the wall recess can be very positively encased with the armor plate.
- the corner armor region has a cantilever plate which protrudes at an angle from a side plate.
- the side plate of the armor can be adapted to the side wall of the shredder, which limits the working space, while the cantilever is guided around the recess of the side wall.
- the angle is particularly preferably at right angles, but is preferably at least approximately 70 ° with respect to a profile of the side plate.
- the sidewall armor is particularly stable.
- the cantilever plate has an at least substantially the same thickness as the side plate.
- the thickness of the cantilever should make at least about half of the thickness of the side plate, preferably about two thirds of the thickness of the side plate according to previous experiments with prototypes.
- the side plate itself is preferably thicker. leads, as can be arranged in it, inter alia, Verschraubungs techniquen for the side wall armor.
- the stated object solves a side wall armor for a shredder, in particular for a shredder for sheets, motor vehicles and the like, for lining its side wall, wherein a transition between a side plate and a rotor chamber plate having a cantilever.
- the object is achieved by a shredder for sheet metal, motor vehicles and the like, having a rotor mounted in a housing, the rotor having a rotor edge under a side wall of the housing or a side plate of a sidewall armor with a remaining free gap, wherein a free gap of at most 10 mm, preferably of at most 5 mm, more preferably of at most 2 mm, is present.
- the stated object solves a shredder for sheets, motor vehicles and the like, with a rotor mounted in a housing, wherein the rotor with a rotor edge under a side wall of the housing or a side plate of a side wall armor rotate can, and wherein an overlap of side wall or side plate over the rotor shell surface is at least 20 mm, preferably at least 40 mm, more preferably about 50 mm, each measured from the rotor edge.
- the stated object solves a rotor for a shredder for sheets, motor vehicles and the like, with a rotor mounted in a housing, which can rotate with a rotor edge under a side wall of the housing or a side plate of a sidewall armor wherein the rotor has a radial projection on the edge of the rotor for reducing the material passing through a gap between the edge of the rotor and the side wall or side plate.
- a rotor with a radial projection has rotor caps.
- Such rotor caps are known for example from DE 197 56 275 Cl.
- the rotor in addition to protruding hammers on the circumference of the rotor shell at the axial edge of a circumferential projecting ring on the disc of the rotor, on which a protective cap is placed.
- the rotor of DE 197 56 275 Cl thus has an approximately smooth surface on the circumference. This smooth surface - with the exception of the individual protruding hammers - is formed by the cylindrical mantle surface around the numerous protective caps on the rotor.
- the proposed sixth aspect of the invention proposes to form a radial projection on the edge, especially during operation, in order to retain as much shredded material as possible in its unplanned axial movement in the working space.
- the projection is formed radially on the outside of a rotor cap, preferably on an edge rotor cap.
- the stated object solves a rotor for a shredder for sheets, motor vehicles and the like, with a rotor mounted in a housing, wherein the rotor with a rotor edge under a side wall of the housing or a side plate of a sidewall armor and wherein a radial recess is provided on the side wall and / or the side plate, in which the rotor edge can rotate, for reducing passing through a gap between the rotor edge and side wall or side plate Schredguts.
- the shredder is - in simple terms - the recess in the housing wall or in their armor provided with a circumferential recess, so that the edge of the rotor can be fitted into this recess, which also the passage of Shredded material reduced in the free space on the side of the rotor end faces or completely prevented if possible.
- a suitable design results in the cross section of the shredder with rotor, a gap between the working space and the free space next to the rotor end with a Step. The annular gap around the rotor accordingly leads into the recess.
