- the invention relates to a shredder for material of any kind, for. B. waste, such as household waste and bulky waste or wood, comprising a receptacle provided for the material in a housing, at least one driven shaft on which comminution tools are provided and rigid cutting tools arranged in the housing as counter-tools for the comminution tools for comminuting the material.
- waste such as household waste and bulky waste or wood
- the comminution tools are known to be formed from U-shaped knives which lie in a plane perpendicular to the axis of rotation for the shafts and which are uniformly along and around two essentially parallel and horizontal shafts which are driven by a motor , which can drive the shafts in opposite directions, and which have a mutual distance which is slightly larger than twice the distance between the radial outer point of a knife and the axis of rotation.
- the drive devices are provided between the motor and the shafts.
- the material is fed to the knives through a shaft arranged above the knives. These knives cooperate with knives fixed between the shafts on part of the frame of the material crushing device when the shafts rotate in opposite directions, thereby moving the cutting edge of the blades on the top of the fixed knives towards each other.
- the drive means also include, in a known manner, a suitable transmission for each of the two shafts, a hydraulic motor with adjustable rotational speeds for operating each shaft, an adjustable pump for supplying each hydraulic motor and transmission through which the motor operates the pumps which flow through the hydraulic motors are able to reverse to individually rotate each shaft back and forth according to a predetermined sequence.
- each knife comprises two essentially U-shaped blades arranged one behind the other, that the radially outer and front parts of the two blades, viewed in the direction of rotation of the cutting movement of the knives , are constructed as essentially tangentially oriented wedges, that the distance between the axis of rotation and the wedge of the front blade is shorter than the distance between the axis of rotation and the wedge of the subsequent blade and that the radially outer contour of the subsequent blade is essentially a segment of a corresponds to a spiral line around the axis of rotation.
- the fixed knives are formed by a known cutting table which is arranged on the bottom of a funnel with at least one set of fixed, parallel lower knives, which are separated from one another by openings through the table.
- At least one rotatable shaft of a drive unit is provided, which shaft is arranged above the cutting table in a direction that extends perpendicular to the lower knives.
- each knife having a number of teeth and partially extending down into each of its openings in the table.
- Each opening is wider than the associated upper knife, which is also located near one of the lower knives in the associated opening.
- the lower knives extend in a direction that intersects the axis of the shaft or a region around it, with this embodiment assuming that a cutting table is already known in accordance with DK 169 378 whose level already extends below the wave.
- a set of several knives is arranged on each side of the shaft, the arrangement of which forms a V or an inverted V with respect to one another.
- the respective cutting edges can be curved or wavy.
- a shredder for materials such as organic waste, bulky waste or the like which has been put together and described above in accordance with the documented prior art, still has disadvantages, despite its proven function, which consist in particular in that
- the stability of the shredding tools attached to the shaft is compromised, the effectiveness of the shredding process is limited by the fixed knives, the throughput cannot be increased due to the effect of the shape of the shredding tools on the shaft, in interaction with the fixed knives, and the The machine's energy consumption is relatively high.
- the invention has for its object a crushing machine for material of any kind, for.
- waste such as household waste and bulky waste or wood, in particular organic waste, bulky waste, such as refrigerators, tires, furniture, carpets, mattresses, tree stumps, demolition wood or similar materials, which includes
- a receptacle provided in a housing for the material, at least one shaft on which comminution tools are arranged, rigid cutting tools attached in the housing, the cutting edges of which, in their extension, do not intersect the axis of the shaft or an area around the axis against which rigid cutting tools the shaft crushing tools cut the material being fed.
- the shredding machine for production, operation, maintenance and repair must be designed in suitable assemblies, and on the other hand it must be controllable for the conditions of the shredding process.
- the comminution tools in each case in a direction of rotation of the shaft and in its cross section has at least two cutting areas, of which at least one inner cutting area can grasp and shred more material and therefore has a relatively small lever arm, and at least one outer cutting area less to shredding Can grasp and shred material and has a relatively large lever arm, the cutting contours of both cutting areas in the direction of the axis of the shaft form a circular arc around the axis of the shaft, b) the rigid cutting tools have several saw-like teeth and thus two at an angle to each other Tooth flanks of the teeth work with one of the cutting areas, c) in each effective cutting position that begins, a tip of the shredding tools forming a first cross cutting edge against a second cross cutting edge Forming tip of a tooth of the rigid cutting tools is offset in parallel and directed past, whereby in addition to the cutting forces generated between the cutting areas of the shredding tools and the cutting edges of the rigid cutting tools, an additional breaking edge directed parallel to the axis of the shaft with
- the comminution tools are offset from one another in the axial direction on the shaft or are arranged at a different radial distance, the teeth also correspondingly being arranged on the rigid cutting tools, which cutting tools run as so-called slabs.
- the shaft has disks on which the comminution tools are arranged or formed. These comminution tools work with the teeth, intermeshing between the rigid cutting tools of the slab arranged at a distance.
- the shaft In order to be able to assemble and disassemble the shaft cheaply, it has pins on both sides, which are detachably connected to the shaft and possibly form a bearing area.
- the connection can be designed so that it is made using flanges.
- the housing is double-walled on the end faces, and in between a labyrinth-like seal against material leakage, a disk connected to the shaft is provided, which can expediently be formed by the flanges.
- the cutting contours of the saw-like teeth of the rigid cutting tools can be formed by wear elements which, for. B. are interchangeable.
- a control is used to further optimize the comminution process, which receives its command variables from at least one gradient of a parameter of the comminution process.
- FIG. 1 shows a top view according to FIG. 1
- FIGS. 1 and 2 shows the cross section corresponding to FIGS. 1 and 2 in a simplified representation of the features essential to the invention of the phases of the operating principle of the invention between the comminution tools and the rigid cutting tools in the working phase of the material which has been fed in and has not yet been comminuted,
- a comminution machine for domestic waste, bulky waste or wood, as shown in FIGS. 1 and 2, consists of a housing 1 with two counter-driven shafts 2 mounted therein. On the shafts 2, disks 2.1 are arranged which have comminution tools 3. These crushing tools are arranged at a distance from one another on the shafts 2 in such a way that they work in parallel with one another in cooperation with rigid cutting tools 4, which run as a slab in the axial direction of the shafts 2, and shred a material 5 that is fed in via a receptacle 1.2.
- the comminution tools 3 each have a cutting area 3.1, 3.2 in a direction of rotation of the shafts 2 and in their cross-section, which are designed such that the stability of the comminution tools 3 is not endangered.
- An inner cutting area 3.1 captures more material 5 to be comminuted and acts with a relatively small lever arm
- an outer cutting region 3.2 captures less material 5 to be comminuted and acts with a relatively large lever arm.
- the contours 3.3 of said cutting areas 3.1, 3.2 each describe a concentric circular arc around the shafts 2 in the direction of the axes of the shafts 2.
- the rigid cutting tools 4 have a plurality of teeth 4.2 arranged in a saw-like manner.
- two tooth flanks 4.3 of the teeth 4.2 which are at an angle to one another work together with at least one of the cutting edge regions 3.1, 3.2 in such a way that the respective material 5 is always clamped in and is notched and cut all around by the available edges of the cutting edges.
- this comminution machine does better justice to the types of material 5 outlined in the comminution practice in that
- FIG. 3 it is shown schematically how the cutting areas 3.1, 3.2 acting with different lever arms can grasp the material 5 in different volumes and distribute it on the rigid cutting tools 4 between the tooth flanks 4.3 in such a way that the comminution is optimally prepared.
- FIG. 5 shows in particular the phase in which the outer cutting areas 3.2, with the large lever arm and the less captured material 5, act against the rigid cutting tools 4.
- the comminution tools 3 are arranged radially offset from one another in the axial direction on the shafts 2 in accordance with FIGS. Not shown in the figures is the possibility that the crushing tools 3 in a different angular position on the shaft 2, ie axially in the cutting profile, for. B. tapered are arranged. Accordingly, the teeth 4.2 of the rigid cutting tools 4, which run axially as a slab, are also to be arranged.
- the technologically favorable design for the manufacture, operation, maintenance and repair of the comminution machine according to the invention is achieved with the features further shown in FIG. 1.
- the shafts have 2 pins 2.2 with a bearing area at the ends. The connection between the pin 2.2 and the shaft 2 is made by means of flanges 2.3.
- the housing 1 is designed according to Figure 1 on the end faces with a double wall 1.1, in which the pins 2.2 or ends of the shaft 2 have a sealing washer 2.4, which forms a sealing labyrinth with the double wall 1.1.
- the sealing washer 2.4 is formed by the flanges 2.3.
