Definitions

  • the invention relates to a machine designed to fragment raw blocks of a natural organic material, such as wood, or synthetic, such as a polymer or a derived material.
  • a natural organic material such as wood
  • synthetic such as a polymer or a derived material.
  • fragment here denotes indifferently any operation consisting in particular of cutting, defibrating, reducing, or calibrating the treated material.
  • the products obtained may, in particular, be in the form of platelets, chips or fibers.
  • the machine according to the invention can in particular be used to obtain fibers for the subsequent manufacture of particle boards, paper, etc.
  • the machine according to the invention can be used to treat or recycle certain products, as well as waste.
  • the fragmentation of blocks of a material such as wood is effected under optimal conditions when the three parameters of the tangential cutting speed, the speed of advance of the product and the projection of the cutting blades are controlled.
  • the pieces of wood are channeled in a pipe to a horizontal or vertical disk, provided with cutting blades positioned radially.
  • Cylinders associated with the pipe control the advance of the pieces of wood, at a generally adjustable speed and can be constant.
  • Machines of this type make it possible to control two of the parameters which it is necessary to control to work in the best conditions. These two parameters are the protrusion of the cutting blades and the speed of advance of the product.
  • the cutting speed is variable and scalable depending on the distance between the cutting zone considered center of the disc. It is therefore not possible to control the tangential cutting speed. Therefore, this type of machine does not work in the best conditions.
  • cutting blades are fixed in a static or rotating basket, parallel to its axis, and a central impeller rotates at high speed inside the basket.
  • This type of machine makes it possible to control the protrusion of the cutting blades, as well as the cutting speed.
  • the speed of advance of the products introduced in the center of the machine and centrifuged by the impeller is random.
  • this speed of advance which results from the centrifugal force applied to the treated products, decreases proportionally to the reduction of the volume of the product during the fragmentation operation.
  • the feed rate of the product is therefore not controlled, nor the energy consumption of the main engine. Therefore, this type of machine does not allow to work in optimal conditions either.
  • the invention specifically relates to a fragmentation machine blocks of a material, such as wood, whose original design allows it to work in the best conditions, controlling both the tangential cutting speed, the speed of advance of the product, the protrusion of the cutting blades and the energy consumption of the main motor.
  • this result is obtained by means of a machine for breaking up blocks of a natural or synthetic organic material, such as wood, according to claim 1.
  • the machine according to the invention makes it possible to control both the tangential cutting speed and the feed rate of the product, which is not the case in any of the existing machines.
  • the machine according to the invention makes it possible to work under optimal conditions.
  • the advance control means are able to advance the blocks at a constant speed.
  • they preferably include means for adjusting the speed.
  • regulation means responsive to the energy absorbed by the rotation control means drive the advance control means to ensure a substantially constant total energy consumption.
  • the advance control means can take different forms. In the preferred embodiment of the invention, they comprise an Archimedean screw housed in the feed channel, as well as a drive motor for this screw. Alternatively, the advance control means may also be constituted by a jack-push assembly.
  • the cutting members are mounted on external anvils, integral with the basket, by removable fixing means.
  • These dismountable fastening means preferably comprise, for each cutting member, an internal clamping wedge adapted to apply the cutting member against the anvil, under the effect of the centrifugal force generated by the rotation of the basket, to the less a connecting member connecting the clamping wedge to the anvil with a clearance allowing assembly and disassembly of the cutting member, and elastic means urging the clamping wedge towards the anvil, against the aforementioned game.
  • Each connecting member may then comprise a screw, screwed into the clamping wedge, freely passing through the anvil and provided with a disassembly head accessible from outside the basket.
  • Each of the cutting members may in particular comprise a blade fixed on a blade holder, for example by means of screws, positioning fingers or by interlocking.
  • said channel advantageously comprises a dump hatch in a part situated outside the basket.
  • the feed channel is preferably movable, for example tilting or sliding, relative to the basket.
  • the supply channel can then be brought into a maintenance position, in which it is completely outside the basket.
  • the rotating basket can be mounted coaxially inside a static basket including a cylindrical wall includes, alternately, rasps and calibration zones. Percussion irons are then attached to the rotating basket, and mounted between the latter and the static basket, close to the cylindrical wall of the latter.
  • the rotating basket is generally supported and surrounded by a fixed housing provided with an access door for the replacement of cutting members.
  • the axis of the rotary basket is substantially horizontal and a single inclined and ascending supply channel opens near the upper generatrix of this basket.
  • the axis of the rotating basket is substantially horizontal and two substantially horizontal supply channels enter the basket, on either side thereof.
  • the axis of the rotary basket is substantially vertical and several inclined and descending supply channels open into said basket.
  • the machine comprises a frame 10, which rests on the ground 12 above a well 14.
  • the frame 10 is provided with means, such as a bearing 16, adapted to rotatably support a basket 18 in the form of a drum.
  • a bearing 16 adapted to rotatably support a basket 18 in the form of a drum.
  • the axis 20 of the rotary basket 18 is substantially horizontal.
  • the rotating basket 18 is placed above the well 14.
  • Means 22 for controlling the rotation of the basket 18, such as an electric motor carried by the frame 10, are provided for driving the basket 18 in rotation about its axis. 20, via a shaft 24 mounted in the bearing 16.
  • the frame 10 comprises a casing 26 which completely envelopes the basket 18, with the exception of the lower part thereof situated above the well 14.
  • the basket 18 comprises a flange 28 fixed in its central part to the shaft 24, a cylindrical cutting portion 30, which will be described in detail hereinafter, and an annular disc 32, connected to the periphery of the flange 28 by the cylindrical cutting portion 30.
  • the fragmentation machine further comprises a feed channel 34 whose axis is contained in a plane passing through the axis of rotation 20 of the basket 18 and inclined, for example by approximately 45.degree. relative to this axis 20.
  • the feed channel 34 is arranged such that its closed, low end is located outside the basket 18 and the frame 10, on the opposite side to the rotation control means 22. On the contrary, the open, upper end of the feed channel 34 is placed inside the basket 18 and opens into the latter in the immediate vicinity of the highest generatrix of the cutting region 30. Between its two ends, the feed channel 34 passes through an opening formed in the housing 26 and is fixed to the frame 10. The channel also feeds through a circular opening formed in the annular disk 32.
  • Advance control means are associated with the feed channel 34, in order to convey at a controlled advance speed blocks or pieces of the material to be broken up to the cylindrical cutting portion 30 of the basket 18. according to an upward movement within the channel 34.
  • these advance control means comprise an Archimedean screw 36 mounted coaxially in the feed channel 34, as well as a drive motor 38 of the screw 36, such as than a regulated electric motor.
  • the advance control means may also be constituted by a push cylinder or by any similar device.
  • the blocks or pieces of material to be fragmented are introduced into the bottom of the supply channel 34, outside the casing 26, by a chute or vertical hopper 40 opening directly into the lower part of the channel.
  • the fragmentation machine according to the invention makes it possible to control both the feed rate blocks of material to be fragmented and the tangential cutting speed of these blocks. Since the control of the protrusion of the cutting blades does not pose any particular problem, the machine according to the invention therefore makes it possible to work in the best possible conditions.
  • the advance control means constituted by the Archimedes screw 36 and the motor 38 in the mode of embodiment shown, are designed so as to ensure the advance of the blocks of material in the feed channel 34 at a constant speed.
  • means for adjusting this speed are advantageously provided, for example at the motor 38.
  • regulation means associated with the motor 38 can make it possible to ensure a substantially constant total energy consumption on the machine.
  • the regulation means receive signals representative of the energy absorbed by the motor 22 ensuring the rotation control of the basket 18.
  • the control means determine, from these signals, the energy remaining available for the motor 38 and it is controlled accordingly.
  • a hatch 35 placed in the lower part and on the lower face of the supply channel 34, outside the casing 26, empties the channel at the stop of the machine. After opening of the hatch 35, the channel 34 is emptied by controlling a rotation in the opposite direction of the Archimedean screw 36, using the motor 38.
  • the cylindrical cutting portion 30 of the basket 18 (FIG. 1) is in the form of external anvils 46, positioned over a certain radius with respect to the axis 20 of the basket. and spaced circumferentially from each other by a small predetermined distance.

More specifically, the cutting member 44 comprises a blade holder 56 which is housed in the bottom of the recessed portion 54, and a cutting blade 58, fixed to the blade holder 56 and flush with the leading edge 50 when the cutting member 44 is placed in the hollow portion 54. The cutting edge 60 of the cutting blade 58 then protrudes forwardly and inwardly, over predetermined distances, respectively with respect to the anvil 46 and with respect to a wear shoe 62 mounted inside the anvil 46, on an inner clamping wedge 64.
