Definitions

  • the present invention relates to an apparatus for reducing branches of chips, chips or particles whose dimensional qualities are acceptable for fuel use (domestic or industrial boilers).
  • the particles from these machines are of variable size, especially with regard to disk machines. Indeed, in the latter case, the detached particles of the branch through the disk and are propelled into a discharge chute by a fan which is mainly constituted by fins integral with the rear face of the disk. It is therefore not uncommon for the endings of the branches thus cross the disc without having been cut despite a length much greater than the largest dimension of a chip. These too long particles are not adapted to the destination as the wood fuel thus treated and lead to the disqualification of production for this application.
  • the present invention is an apparatus for forming disc-type wood chips in which the cutting means are arranged so that no particle has a dimension greater than those imposed by the destination of the chips as a fuel and this, without to sacrifice the performance of the machine nor to impose an overpower on it which would place it unfavorably in competition with the drum machines.
  • a plant crusher for the production of platelets or calibrated wood particles presenting itself as a conventional disk mill, in the form of a housing closed by a front wall, a bottom wall and a substantially cylindrical side wall.
  • the front wall has an inlet opening of the wood to be treated lined with at least one fixed blade, and the side wall has an outlet opening of the wafers or particles.
  • the bottom wall is traversed by a motor shaft.
  • the distance separating the side wall of the shredding chamber from the casing side wall defines the maximum size of the particles.
  • the calibration chamber is scanned by at least one cutting finger secured to the periphery of the disk so that a long particle is blocked across the calibration chamber and is sheared at the passage of the cutting finger. This finger also plays the role of a scraper discharging the particles of the calibration chamber towards the chamber of the blower.
  • the mill of the invention therefore comprises a housing 1, delimited by a front wall 2, a rear wall or floor 3 and a side wall or peripheral 4 substantially cylindrical.
  • the front wall is provided with an opening 5 comprising here a fixed blade or counter blade 6a substantially horizontal and a fixed blade or against blade 6b substantially vertical. Through this opening is introduced the end of the branch to reduce chips. Under the cutting force, this branch tends to stall in the angle formed by the two against blades.
  • the bottom wall 3 of the housing is traversed by a drive shaft 7 and a bearing 8 is provided for this purpose.
  • This wall is also provided with louvers 9 which form air inlet openings inside the housing.
  • the side wall 4 of the housing has an outlet opening 10 located in such a way that the conduit 11 which extends it forms a tube which escapes from the housing tangentially to the wall 4 of the latter.
  • a disc 12 is rotatably mounted in the direction of the arrow A of the figures, fixed on the drive shaft 7 itself supported by the bearing 8.
  • the diameter of this disc is less than the inner one of the side wall 4 of the housing for the reasons that will be explained below.
  • the front face of the disk that is to say that 12a turned towards the front wall 2 of the housing, carries a cutting tool 13 constituted by a base 13a fixed by any suitable means to the surface of the disk which forms the support of several cutting pads 13b, reported on this base by screws 13c front access.
  • the cutting inserts extend along a substantially spiral curve from the vicinity of the center of the disc to the periphery thereof. The plane swept by these pads is immediately behind the plane that contains the back edge of the blades. It is understood that the wood introduced into the opening 5 (window) is nibbled (shredded) at each passage of a line of cutting inserts 13b.
  • the plates 13b will be arranged so that the surface swept by the cutting edge of one of them overlapping with the surface swept by the cutting edge of the wafer or neighboring wafers.
  • the circle on which the innermost end of a cutting edge travels is of smaller radius than the circle traversed by the outermost end of the cutting edge of the plate which is adjacent thereto. side of the center of the disc.
  • the base 13 thus has, in the case illustrated by the attached figures, two rows of cutting inserts. At the end of each of these lines, the base has another cutting tool 13d, also in the form of inserts plate, whose attachment to the base is formed by screws 13th radial access. The surface swept by the cutting edge of these plates is of diameter equal to that of the disk.
  • the thickness of the base 13 defines the axial dimension (in the direction of the axis 7) of a shredding chamber (nibbling) delimited in the casing 1 by the front wall 2 of the latter, by the disk 12 and by a side wall secured to the front wall and shown in FIG. the figure 6 .
  • the front wall 2 is in two parts: a fixed lower portion 2a, integral with the side wall 4 of the housing and an upper portion 2b shaped like a hinged door around a hinge 2c.
  • the window 5 is reduced to a cut of the door 2b while the against blades 6a and 6b are carried by the fixed portion 2a of the front wall.
  • the side wall of the shredding chamber is, because of this construction of the front wall 2 in two portions: a portion 14a secured to the door 2b on its inner face and a portion 14b carried internally by the fixed portion 2a of the wall 2.
  • this wall 14a, 14b continues when the door is closed, constitutes the envelope of the volume swept by the base 13 and the tools 13b and 13d which it is equipped with, during the rotation of the disk 12.
  • the portion 14b of this wall is provided with a plurality of perforations 15 opposite the wall 4 of the housing while the portion 14a of this wall is devoid of it, at least in the zone where it is opposite the outlet opening 10 of the housing .
  • the distance d ( figure 6 ) which radially separates the walls 4 and 14 (a and b) defines a maximum particle size engaged in a perforation 15 and abutting the wall 4.
  • This annular space of thickness d is called the calibration chamber.
  • the disk 12 is also equipped with at least one (here two) cutting finger 16 (a and b) which, from the periphery of the disk, extends perpendicular to the latter in the calibration chamber, immediately at the -above of the wall 14a and b. It acts as a secondary knife to intersect the long particles engaged in the perforations 15 and as a sweeping finger of this calibration chamber.
  • the axial length of this finger is substantially equal to the total thickness of the base 13 and the tools it carries.
  • the disk 12 carries on its face 12b turned towards the bottom wall 3 of the casing a series of fins 17 which constitute the blades of a blower whose enclosure (blower chamber) is limited by the disc 12, the rear wall 3 and the side wall 4 of the housing for its part extending beyond the wall 14a and b.
  • the flow of air generated by these blades 15 enters the blower chamber through the openings 9 of the bottom wall of the casing and leaves this chamber through the outlet opening 10 by driving the wood particles that come from the chamber shredding through the wall 14a and b. It is understood that the air flow is not hindered by any obstacle such as a comb or sieve, the calibration of the particles having been performed upstream of the creation of this pneumatic particle transport stream.
  • the wood introduced through the window 5 is reduced to particles by the tools 13b in the chipping chamber.
  • the particles do not pass through the disc to reach the blower. Their path is thus controlled so that they can be calibrated effectively upstream of their pneumatic extraction.
  • the particles whose size is smaller, on the one hand to the diameter of the perforations 15 of the wall 14b and, on the other hand, to the thickness d of the calibration chamber, pass directly through this wall into the chamber. blower where they are driven by the flow of air. Particles that are too large are plated on this wall 14a and b where they are cut or re-shredded by the knife 16a and b to penetrate the perforations 15.
  • the finger 16 comes shear them to a good size.
  • the wall 14a is full opposite and on either side of this opening about 120 to 150 degrees.
  • the crusher according to the invention may have a wall 14 a, 14 b, removably fixed to the casing 2 so that the user can remove it. He then has an ordinary mill that he can use for the sole purpose of a reduction of a plant material without calibration constraints. The mill of the invention can thus be used more cost-effectively.
