  FIG. 1 is a diagram showing a schematic configuration of a waste engine crusher 1 according to an embodiment of the present invention.

  In addition, in FIG. 1, the state which removed the front panel (member which comprises a side wall) of the waste engine crushing apparatus 1 is shown.

  As with the conventional waste engine crushing device 100, the waste engine crushing device 1 uses a nibler to primarily crush a waste engine (for example, a car waste engine) into a primary crushed material, an aluminum material and iron. It is an apparatus that can be further finely crushed to obtain a secondary crushed material in order to physically separate it into a system material.

  The waste engine crusher 1 includes a housing 3 having a space inside and having a rectangular parallelepiped shape. A movable blade installation member in which a movable blade (blade tool) 5 can be installed in the housing 3. 7 and a fixed blade installation member 9 on which a fixed blade (blade) 8 can be installed.

  Further, the movable blade 5 is detachably attached to the movable blade installation member 7 by using a fastener such as a bolt. Similarly, the fixed blade 8 is also detachable from the fixed blade installation member 9.

  In addition, an intake port 11 for taking in the primary crushed material to be processed is provided above the housing 3, and a discharge port 13 for discharging the obtained secondary crushed material is provided below the housing 3. Is provided.

  The movable blade installation member 7 is provided so as to extend substantially in the vertical direction, the upper side is connected to the operating shaft of an actuator (for example, a fluid pressure cylinder) 15, and the lower side is provided to a rotating shaft (provided on the housing 3). (Rotating shaft) 17 is rotatably supported.

  The fluid pressure cylinder 15 enables the movable blade installation member 7 to reciprocate between the retracted position indicated by the solid line and the advanced position indicated by the two-dot chain line (oscillate around the rotating shaft 17). Yes.

  On the other hand, the fixed blade installation member 9 is provided with a slight inclination with respect to the substantially vertical direction, and can be moved in the inclination direction by an actuator (for example, a fluid pressure cylinder) 19 as necessary. Note that, in a normal use state (a state in which the waste engine crusher 1 is movable to obtain a crushed material), the fixed blade installation member 9 is located below and located above during maintenance or the like. Is.

  When the movable blade installation member 7 to which the movable blade 5 is attached is in the retracted position, the fixed blade installation member 9 to which the fixed blade 8 is attached so that an appropriate amount of primary crushed material can be stored and subjected to secondary crushing; A “V” -shaped space is formed between the movable blade installation members 7.

  On the other hand, when the movable blade installation member 7 to which the movable blade 5 is attached is in the forward movement position, the movable blade 5 and the fixed blade 8 are arranged so that the movable blade 5 and the fixed blade 8 are substantially parallel to each other. The primary crushed material can be further finely crushed.

  Note that when the movable blade 5 (movable blade installation member 7) is in the retracted position, the distance between the lower portion of the movable blade 5 and the lower portion of the fixed blade 8 is such that the primary crushed material does not fall but the secondary crushed material is It is an interval that can be dropped.

  For example, a belt conveyor is installed below the crushing apparatus 1 so that the secondary crushed material can be transported to the next process so that the aluminum material and the iron material can be efficiently separated. It is desirable to do so. Further, it is desirable to provide a cover (not shown) above the housing 3 in order to prevent the crushed material from scattering.

  Here, each said blade 5 and 8 used for the said waste engine crushing apparatus 1 is demonstrated in detail.

  2 is a perspective view showing an overview of the cutting tool 5, FIG. 3 is a view taken in the direction of arrow III in FIG. 2, and FIG. 4 is a view taken in the direction of arrow IV in FIG.

  FIG. 5 is a view showing a case where the cutting tools 5 and 8 are installed on the installation members 7 and 9 and are swung (rotated). 5A shows a state in which the movable blade installation member 7 (movable blade 5) is in the retracted position, and FIG. 5B shows the movable blade installation member 7 (movable blade 5) in the advanced position. Shows the state.

  FIG. 6 is a view showing the VI arrow in FIG.

  An overview of the movable blade 5 is formed in a rectangular plate shape, and a planar portion 21 formed in a rectangular shape is provided on one side in the thickness direction.

  The planar portion 21 is provided with a plurality of grooves 23 having a predetermined width and a predetermined depth. These grooves 23 are spaced in the width direction of the planar portion 21 (the cutting tool 5), and from one end portion in the longitudinal direction of the planar portion 21 to an intermediate portion (for example, about 1 / from the one end portion in the longitudinal direction). 3).

  It should be noted that the depth of the groove 23 is gradually reduced at a portion of each groove 23 opposite to the one end portion (intermediate portion in the longitudinal direction of the planar portion 21). Therefore, a slope 23A is formed at a portion where the groove 23 moves to the planar portion 21 so that the crushed material can move smoothly.

  At the locations where the grooves 23 are formed, the width of the grooves 23 is wider than the width of the locations 25 where the grooves 23 are not formed. For example, the width of the groove 23 is twice to four times (preferably about three times) the width of the portion 25 where the groove is not formed.

  Further, projecting portions 27 protruding from the planar portion 21 are formed at both ends in the width direction of the planar portion 21 so as to extend over almost the entire length of the planar portion 21 in the longitudinal direction.

  For example, the protruding portion 27 is formed such that a cross section of a plane perpendicular to the longitudinal direction of the planar portion 21 is a right triangle. Furthermore, the base of the right triangle exists on the extension line of the planar portion 21, the side perpendicular to the base exists on the extension of the side surface (side surface in the width direction) of the blade 5, and the right triangle Each projecting portion 27 is provided so that the oblique side faces the inside of the planar portion 21.

  Further, in the cross section of the planar portion 21 by a plane perpendicular to the longitudinal direction, the crossing angle between the oblique side and the planar portion 21 is, for example, about 135 °.

  The hypotenuse may be formed not by a straight line but by a curve whose height decreases as it goes inward in the width direction (see two-dot chain lines L1 and L3 in FIG. 3).

  On both side surfaces of the cutting tool 5 in the width direction (width direction of the planar portion 21) and in the middle of the thickness direction of the cutting tool 5, the longitudinal direction of the cutting tool 5 (the longitudinal length of the planar portion 21). A groove 29 having a predetermined width and a predetermined depth is formed so as to extend over almost the entire length in the direction).

  The fixed blade 8 is also formed in substantially the same form as the movable blade 5. Each of the cutting tools 5 and 8 constitutes a set of cutting tools. The blades 5 and 8 are arranged so that the longitudinal direction thereof is substantially vertical, and so that the groove 23 is positioned upward, that is, facing the intake port 11 side where the crushed material enters. , And installed on the installation members 7 and 9.

  Further, as already understood, the cross-sectional shape of each groove 23 of each of the cutting tools 5 and 8 (the cross-sectional shape by a plane perpendicular to the longitudinal direction of the cutting tools 5 and 8) has a predetermined width and a predetermined depth. It is formed in the rectangular shape provided with.

  Then, the blades 5 and 8 are overlapped with each other such that one end portions in the longitudinal direction are aligned with each other and the planar portions 21 are substantially aligned with each other, that is, the end surfaces and the widths of the blade tools 5 and 8 in the longitudinal direction. When the edge tools 5 and 8 are overlapped with each other in the thickness direction and viewed from the direction perpendicular to the planar portion 21, the grooves 23 in one of the blade tools 5 in the blade tool set 5 are aligned. Are not formed, and locations 25 where the groove 23 is not formed in the other cutting tool 8 of the cutting tool set are alternately arranged in the width direction of the cutting tools 5 and 8 (FIG. 6).

  That is, as described above, when the cutting tools 5 and 8 are overlapped with each other, the portion where the groove 23 is not formed (the portion where the planar portion remains between the grooves 23) 25 is, for example, Are arranged alternately at a predetermined pitch.

  Further, as shown in FIG. 6, four blades 25 are formed in one of the blades 5, so that four portions 25 where the groove 23 is not formed are formed. Since the two grooves 23 are provided, three portions 25 where the grooves are not formed are formed.

  Since the groove 23 is wider than the portion 25 where no groove is formed, more precisely, the portion where the groove 23 of the blade 5 is not formed and the groove 23 of the blade 8 are not formed. The points 25 are lined up apart from each other.

  In each of the blades 5 and 8, as described above, since the grooves 23 (locations 25 where no grooves are formed) are alternately formed, it is possible to efficiently crush the primary crushed material having a relatively large particle size. it can.

  By the way, the cutting tool 5 and the cutting tool 8 may be exchanged and installed in the waste engine crushing apparatus 1.

  Next, the operation of the waste engine crusher 1 will be described.

  The movable blade installation member 7 reciprocates, and the primary crushed material is intermittently supplied from the intake port 11 according to the swinging of the movable blade installation member 7 and intermittently secondary crushed from the discharge port 13. It is assumed that things are being discharged.

  The state shown in FIG. 5A, which is one of the movable states, is a state where the movable blade 5 is in the retracted position and the primary crushed material is introduced from the intake port 11.

  In the state shown in FIG. 5 (a), the primary crushed material (primary crushed material that has been introduced but not crushed) W <b> 1 taken in from the intake port 11 exists on the upper side of each of the blades 5, 8. The crushed material W3 crushed to a certain size in the previous crushing is present on the lower side of the blades 5 and 8.

  Subsequently, when the movable blade 5 moves to the forward position as shown in FIG. 5B, the crushed materials W1 and W3 are crushed. For example, the crushed material W3 is crushed to the size of the secondary crushed material, which is the production result of the waste engine crushing device 1, and the crushed material W1 is crushed to the size of the crushed material W3.

  Thus, since a crushed material is crushed several times, for example, a primary crushed material is reliably crushed to the magnitude | size of a secondary crushed material. In addition, the crushing of the crushed material W3 having a small particle size generally requires a larger force than crushing the crushed material W1 having a large particle size, but the waste engine crushing device 1 uses the lever principle. Since a large force is applied to the lower side of each blade 5, 8, a secondary crushed material can be obtained with certainty.

  Furthermore, since each groove | channel 23 is provided above each said blade tools 5 and 8, the large particle size crushed material W1 can be reliably crushed into the small particle size crushed material W3, each said blade tool 5, Since the planar portion 21 is formed below 8, the crushed material W3 having a small particle size can be reliably crushed into a finer secondary crushed material.

  Subsequently, when the movable blade 5 moves from the state shown in FIG. 5B to the retracted position, the secondary crushed material is discharged from the discharge port 13.

  Thereafter, when the primary crushed material is taken in from the intake port 11, the state shown in FIG.

  According to the waste engine crusher 1, the same effect as the conventional waste engine crusher 100 can be obtained.

  In other words, since the method of separating the aluminum-based material and the iron-based material using a blast furnace is not adopted, the waste engine can be efficiently disassembled in a short time, and a recycled material with high added value and excellent quality can be obtained. In addition, since the equipment for preventing the generation of exhaust gas and the maintenance of the blast furnace are not required, useless capital investment and manpower are not required, and the waste engine can be recycled at a significant cost reduction.

  Moreover, according to the waste engine crushing apparatus 1, since the cutting tools 5 and 8 for obtaining a primary crushing material are formed in the shape mentioned above, the iron-type thin plate-shaped member currently used for a clutch etc. is a cutting tool. The crushed material (the material to be crushed or the crushed material) is not easily caught on the blades of the blades 5 and 8 and does not easily stick to the blades 5 and 8. It is possible to prevent the crushed material from becoming clogged and to perform the crushing reliably.

  Moreover, since the protrusion part 27 is formed in the both ends of the width direction of the blade tools 5 and 8, it is obstructed by each of these protrusion parts 27, and a crushed material escapes to the outer side of the width direction of the blade tools 5 and 8 ( It is possible to prevent the crushed material from pushing the wall member 31 of the housing 3 shown in FIG.

  In particular, when the movable blade (blade tool) 5 is brought close to the fixed blade (blade tool) 8 to obtain a secondary crushed material, a compressive force is applied to the crushed material, and the crushed material easily escapes to the outside in the width direction of the blade tools 5 and 8. However, since the outward escape can be prevented by the projecting portions 27, it is possible to avoid the possibility that the wall member 31 of the housing 3 is damaged or worn due to the force.

  Further, since the protruding portion 27 is formed in a triangular shape, as shown in FIG. 6, the tip end portion of the protruding portion 27 becomes a wiper, and the cutting tools 5, 8 and the housing 3 (wall member 31) It is possible to prevent foreign matters such as fine crushed materials from entering a slight gap therebetween.

  Further, since a groove 29 is provided on the side surfaces of the blade tools 5 and 8, the protrusions 27 forming the wiper between the blade tools 5 and 8 and the housing 3 (wall member 31), Even very rarely, foreign matter can be removed by the groove 29.

  In each of the blades 5 and 8, as shown in FIG. 7 (a perspective view showing a modification of the blade), the protruding portion 27 and the groove 29 may be deleted.

  Moreover, in the waste engine crushing apparatus 1, not only the blade 5 but also the blade 8 may be swung.
