<Configuration example of soot processing apparatus 100>
With reference to FIGS. 1-5, the structural example of the wrinkle processing apparatus 100 which concerns on this embodiment is demonstrated. As shown in FIG. 1, the cocoon treatment apparatus 100 includes a substantially cylindrical crushing chamber 10 into which cocoons such as garbage are put, and is installed in a sink 102 of a kitchen.

  The crushing chamber 10 is an example of a crushing blade housing member connected to an input port 101 formed in the upper part of the slag processing apparatus 100, and the input port 101 is exposed to the opening 103 of the sink 102. The crushing chamber 10 is detachably attached in the cocoon treatment apparatus 100. A drainage pipe connection port 104 is formed on the side surface of the soot processing device 100 below the attachment position of the crushing chamber 10. In the dredging device 100, the bottom of the crushing chamber 10 below the bottom surface 10a has a space that is inclined in a direction to be lowered toward the drain pipe connection port 104, although not shown. The slag processing apparatus 100 is configured such that the crushed material (slag) that has been put into the crushing chamber 10 and crushed flows in the direction of the drain pipe connection port 104 with water supplied to the crushing chamber 10.

  The scissor treatment apparatus 100 includes a lid 12 that is detachably attached to the input port 101 of the crushing chamber 10. When the lid 12 is attached to the charging port 101, a water supply hole (not shown) connected to the crushing chamber 10 is formed.

  As a result, the dredging apparatus 100 supplies water into the crushing chamber 10 through the water supply hole of the lid 12 when water is poured into the sink 102 in a state where the inlet 101 is closed by the lid 12. Note that the dredger processing apparatus 100 may include a mechanism for supplying water directly into the crushing chamber 10.

  In addition, the dredge processing apparatus 100 switches between a state in which the lid 12 can be attached to and detached from the insertion port 101 by a rotation operation of the lid 12 with the insertion port 101 closed, and a state in which the lid 12 cannot be attached and detached with the insertion port 101 closed. A lock mechanism (not shown) for locking and unlocking the lid 12 is provided.

  Furthermore, the scissor processing apparatus 100 includes detection means (not shown) that constitutes a crushing start and crushing stop switch by detecting the opening and closing of the lid 12 using a permanent magnet and a magnet sensor.

  That is, in the dredge processing apparatus 100, when the lid 12 with the closing port 101 closed is rotated in a predetermined direction and locked to the charging port 101, the switch is turned on and crushing starts. Moreover, if the lid | cover 12 rotates the cover 12 in the reverse direction and cancels | releases a lock | rock during rotation, it will stop. The crushing operation will be described in detail later.

  FIG. 2 is a partially sectional perspective view in which the side surface 10b of the crushing chamber 10 is partially cut away so that the inside of the crushing chamber 10 can be easily seen. The crushing chamber 10 extends from the crushing shaft 2 extending upward from the bottom surface 10 a and the crushing shaft 2 from the inside to the outside with respect to the rotation direction of the crushing shaft 2, and is spaced from the bottom surface 10 a of the crushing chamber 10. Provided on the inner wall of the crushing chamber 10, the crushing arm 3 disposed with the opening 7 open, the rotating crushing portion 4 extending along the inner wall of the crushing chamber 10 from the rotation direction outer end of the crushing arm 3. The protruding portion 5, the rising crushing portion 6 extending upward from the bottom surface 10a, the rotatable turntable 9 attached to the bottom surface 10a, and the discharge port 8 for discharging the crushed crushed material outside the crushing chamber 10. With.

  The scissor treatment apparatus 100 includes a driving mechanism (not shown) that rotationally drives the crushing arm 3 and the turntable 9 of the crushing chamber 10. The drive mechanism includes a motor, a drive shaft to which the driving force of the motor is transmitted via the speed reduction mechanism, and a control unit that controls the motor. Since the drive shaft communicates with the crushing shaft 2, when the drive shaft is rotated by driving the motor, the crushing shaft 2 is also rotated accordingly.

  In this example, the crushing chamber 10 is made of a resin material. The crushing chamber 10 has a recess 10c for fitting and attaching the rising crushing part 6 to the inner wall of the side face 10b. Further, the crushing chamber 10 has holes 10d and 10e formed vertically in the recess 10c for attaching the rising crushing part 6 with screws 6c and 6d. In this example, the recesses 10c and the holes 10d and 10e are provided at three locations in accordance with the number of the rising crushing portions 6.

  As shown in the exploded example of FIG. 5, the crushing shaft 2 is rotatably mounted so as to protrude upward from below the center of the bottom surface 10 a of the crushing chamber 10. The arm portions 3 are inserted into the center holes 9b and 3b of the arm portions 3, respectively. Therefore, when the crushing shaft 2 is rotated by rotation of a drive shaft (not shown), the crushing arm portion 3, the rotating crushing portion 4 and the turntable 9 are also rotated in the same direction.

  The crushing arm portion 3 extends in two opposite directions around the crushing shaft 2. As shown in FIG. 1, the crushing arm portion 3 is installed with a space 7 opened upward from the bottom surface 10 a of the crushing chamber 10. Thereby, as shown in FIG. 2, a semicircular arc-shaped opening 70 connected to the space 7 is formed between the side of the crushing arm 3 and the inner wall of the crushing chamber 10. The crushing arm 3 has a large gap around the crushing arm 3 by providing the space 7 below and the side openings 70 and the like.

  As shown in FIG. 2, the crushing arm portion 3 tapers from the periphery of the crushing shaft 2 to both ends. The crushing arm part 3 has a convex part 3 a along the long side of the crushing arm part 3 on the upper surface thereof. The crushing arm part 3 agitates the ridges in the crushing chamber 10 during rotation, and the convex part 3a facilitates the agitation. The crushing arm portion 3 has a form in which a metal material is covered with a resin material. By providing the convex portion 3a, the crushing arm portion 3 can be given strength.

  The crushing arm portion 3 of the present embodiment extends in two opposite directions around the crushing shaft 2, but is not limited thereto. The crushing arm 3 may extend from the crushing shaft 2 in one direction or more. When a plurality of crushing arm portions 3 extend, the crushing efficiency of the ridge can be increased. In this example, in order to take the opening 70, the crushing arm portions 3 are provided in two directions.

  The rotary crushing unit 4 is a crushing blade that rotates with the crushing arm unit 3 around the crushing shaft 2. The rotary crushing unit 4 has a tapered shape that tapers toward the bottom surface 10 a of the crushing chamber 10. The rotary crushing part 4 extends vertically downward from the end of the crushing arm part 3 and is made of a metal material. The rotary crushing unit 4 crushes the soot in the crushing chamber 10 between the rotary crushing unit 4 and the protrusion 5 and between the rotary crushing unit 4 and the rising crushing unit 6. By providing the rotary crushing part 4 in parallel with the protruding part 5 and the rising crushing part 6 in the vertical direction, it is possible to increase the vertical length in contact with the crushed material during crushing and improve the crushing efficiency. Can do.

  In the present embodiment, as shown in FIG. 3, the cross-sectional shape of the rotary crushing unit 4 has a shape in which the inner wall side of the crushing chamber 10 is a long side and the crushing shaft 2 side is a short side, and the long side and the short side are parallel. That is, the rotary crushing unit 4 has a substantially trapezoidal cross-sectional shape in a direction horizontal to the bottom surface 10 a of the crushing chamber 10. The long side and the short side may be linear or arcuate.

  In this example, the three protrusions 5 are provided on the inner wall of the crushing chamber 10 vertically from the bottom surface 10a at intervals of about 120 degrees. The horizontal section of the protruding portion 5 has a triangular shape protruding from the crushing chamber 10 toward the crushing axis 2. The protruding portion 5 preferably extends higher than the rotary crushing portion 4. As a result, the cocoon can be crushed with the rotary crushing section 4, and the cocoon pushed against the inner wall of the crushing chamber 10 by centrifugal force and guided upward is guided to the center side and the lower side of the crushing chamber 10. can do. The positional relationship between the rotating crushing portion 4 and the protruding portion 5 is such that the rotating crushing portion 4 is positioned on the inner side in the circumferential direction with respect to the crushing shaft 2 and the protruding portion 5 is positioned on the outer side and on the inner wall side of the crushing chamber 10. is there.

  In this example, the three rising crushing parts 6 are arrange | positioned on the crushing axis | shaft 2 side with respect to the rotation crushing part 4, on the concentric circle of about 120 degree intervals. The cross-sectional shape of the rising crushing part 6 is preferably a substantially trapezoidal shape having a long side on the inner wall side of the crushing chamber 10 and a short side on the crushing shaft 2 side, like the rotary crushing part 4. The rising length of the rising crushing part 6 may be a length capable of crushing the soot when the rotary crushing part 4 rotates and passes the vicinity of the rising crushing part 6.

  In this embodiment, the positional relationship between the rotary crushing portion 4 and the rising crushing portion 6 is such that the rising crushing portion 6 is located inside the circumferential direction with respect to the crushing shaft 2 and the rotary crushing portion 4 is located outside. It is. However, the present invention is not limited to this, and the startup crushing unit 6 may be provided on the inner wall side of the crushing chamber 10 relative to the rotary crushing unit 4, or provided on both the crushing shaft 2 side and the inner wall side of the crushing chamber 10. May be.

  The startup crushing unit 6 is screwed and firmly attached to a crushing chamber 10 made of a resin material. As shown in FIGS. 4 and 5, the rising crushing portion 6 has screw holes 6 a and 6 b in the attachment portion 6 e in a form in which the long side of the flat metal plate is bent. The rising crushing portion 6 rises from the hole 10f of the bottom surface 10a so as to sandwich the bottom surface 10a. The attachment portion 6e is attached to the inner wall of the side surface 10b of the crushing chamber 10 with screws 6c and 6d. The screw 6c is fastened to the screw hole 6a through the hole 10d. The screw 6d is fastened to the screw hole 6b through the hole 10e.

  As shown in FIG. 2, the bottom surface 10 a of the crushing chamber 10 is provided with an arc-shaped discharge port 8 for discharging the crushed soot out of the crushing chamber 10 on a concentric circle with the crushing shaft 2 as the center. Since the crushed soot is guided to the outside by centrifugal force, the discharge port 8 is provided in the form of opening an arc-shaped hole in the vicinity of the side surface 10b of the bottom surface 10a. The discharge port 8 may be a linear slit or may be provided on the side surface 10 b of the crushing chamber 10.

  The turntable 9 has a disk shape. The upper surface of the turntable 9 has a convex portion 9 a protruding upward in a cross shape with the crushing shaft 2 as the center. When the turntable 9 rotates, the ridge is pressed against the inner wall of the crushing chamber 10 by centrifugal force, and the convex portion 9a further promotes the stirring action. Therefore, the turntable 9 and the convex portion 9 a prevent the soot from being accumulated around the crushing shaft 2.

  The shape of the turntable 9 and the convex portion 9a is not limited to this as long as the above-described stirring can be performed. For example, the turntable 9 may have another shape such as a polygon or an indefinite shape. Moreover, the crushing chamber 10 may omit the turntable 9 or the convex portion 9a, or may omit the turntable and the convex portion 9a and rotate the bottom surface 10a.

<Operation example of soot processing apparatus 100>
Next, with reference to FIGS. 1, 2, and 6, the overall operation of the heel processing apparatus 100 will be described. As shown in FIG. 1, when the lid 12 is opened and the crushing chamber 10 is thrown into the crushing chamber 10 from the inlet 101, the inlet 12 is closed with the lid 12, and the lid 12 is rotated in a predetermined direction for locking. A control means (not shown) detects that the insertion port 101 is closed by the lid 12 and rotationally drives a motor (not shown).

  The rotation speed of the motor is set so that the rotary crushing section 4 that is a rotary crushing blade rotates at a low speed of, for example, about 700 rpm, and the generation of noise and vibration is suppressed. During the crushing process, water is supplied into the crushing chamber 10 through a water supply hole formed in the lid 12 by flowing water through the sink 102 or the like.

  When the motor rotates, the crushing shaft 2, the crushing arm unit 3, the crushing crushing unit 4, and the turntable 9 connected to a drive shaft (not shown) rotate together. On the other hand, the protrusion part 5 and the raising crushing part 6 do not rotate.

  As shown in FIG. 2, the soot thrown into the crushing chamber 10 from the inlet 101 is stirred by the crushing arm portion 3, the turntable 9 and the convex portions 3 a and 9 a, and the rotary crushing portion 4 and the protruding portion 5. In addition, it is crushed between the rotary crushing unit 4 and the startup crushing unit 6.

  The stirred soot is pressed against the inner wall of the crushing chamber 10 by centrifugal force. The protrusion 5 on the inner wall of the crushing chamber 10 guides the ridges pressed against the inner wall to the crushing shaft 2 side of the crushing chamber 10. In general, a light and small kite is blown to the upper outside in the crushing chamber 10 by centrifugal force and crushed. On the other hand, heavy and large ridges are guided and crushed below the crushing shaft 2 side rather than light and small ridges.

  As shown in FIG. 1, the crushing arm 3 is installed with the space 7 opened upward from the bottom surface 10 a of the crushing chamber 10, and an opening 70 is provided on the side of the crushing arm 3 as shown in FIG. 2. As a result, even a large kite can be taken into the space 7. In addition, the stirrer that is stirred during the rotation of the crushing arm 3 is easy to move through the gap in the crushing chamber 10. Thereby, the stirred soot quickly circulates in the crushing chamber 10. Therefore, for example, even if it is a large block-like block that cannot be crushed to a size that can be discharged from the discharge port 8 at a time, it is stirred in the crushing chamber 10 and crushed many times. .

  In this embodiment, the crushing arm portion 3 extends in two directions opposite to the crushing shaft 2 and the protrusions 5 are provided at three locations, which are provided so that the number of each is different. . Therefore, the timing at which the two rotary crushing portions 4 pass each other with the protruding portion 5 can be shifted from each other, so that the load during crushing can be reduced.

  Similarly, in this embodiment, the crushing arm portion 3 extends in two directions opposite to the crushing shaft 2 and the rising crushing portions 6 are provided at three locations, and these numbers are different from each other. Is provided. For this reason, the timing at which the two rotary crushing sections 4 are raised from each other and the crushing section 6 can be shifted from each other, so that the load during crushing can be reduced.

  By making the cross-sectional shape of the rotary crushing portion 4 into a trapezoid and arranging the long side on the inside and outside of the crushing chamber 10 and the short side on the crushing shaft 2 side, the acute angle portion of the trapezoid has the triangular portion in the protruding portion 5 side. The obtuse angle part rises and passes the crushing part 6 side.

  As shown in A of FIG. 6, the trapezoidal acute angle portion of the rotary crushing portion 4 passes near the apex of the protruding portion 5 when rotating in the arrow direction in the figure. Thereby, the clearance t1 between the rotary crushing part 4 and the protruding part 5 that sandwich the ridge during crushing can be further reduced. Therefore, a small, light or thin kite that has been blown outward by centrifugal force can be more finely crushed.

  Moreover, as shown to B of FIG. 6, when the obtuse angle | corner part of the trapezoid of the rotation crushing part 4 rotates in the arrow direction in a figure, it passes along the acute-angle vertex vicinity of the starting crushing part 6. FIG. A gap t2 between the rotary crushing portion 4 and the rising crushing portion 6 that sandwiches the ridge during crushing becomes wider than t1. As a result, a large and heavy kite that flies downward inside the small, light or thin kite can be crushed at the acute apex of the rising crushing unit 6 while being received by the wide frontage of the rotating crushing unit 4.

  As shown to C of FIG. 6, the rotary crushing part 4 has a taper shape in which the bottom face 10a side tapers. Thereby, when the rotary crushing part 4 rotates in the direction of the arrow in the figure, the rotary crushing part 4 and the projecting part 5 and the contact with the crushing crushing so as to be sandwiched between the rotary crushing part 4 and the rising crushing part 6 are pointed out. The crushing torque can be reduced close to the contact. In particular, when crushing hard wrinkles, the wrinkles can be reduced from scattering upward. Further, the rotary crushing unit 4 can push the crushed soot into the discharge port 8.

  Although the crushing chamber 10 is made of a resin material, it is possible to crush even a hard flaw by providing the metal crushing unit 6.

  The soot crushed smaller than the size of the discharge port 8 is dropped from the discharge port 8 to the outside of the crushing chamber 10 and discharged from the drain pipe connection port 104.

  The heel processing apparatus 100 stops when the lid 12 is rotated in the reverse direction during rotation to release the lock. For example, the motor is driven to rotate in the forward / reverse direction to rotate the rotary crushing unit 4 in the forward / reverse direction, and control for stopping the driving of the motor after a predetermined rotation time has been performed.

  For example, after the heel processing apparatus 100 rotationally drives the motor for a certain period of time, a control unit (not shown) stops the driving of the motor. The driving time of the motor is set in advance in consideration of the time required for crushing a standard amount of soot introduced into the crushing chamber 10 and discharging it from the drain pipe connection port 104.

  In addition, in the slag processing apparatus 100, you may detect the load applied to the rotary crushing part 4 with the electric current value etc. which flow into a motor. When a load of a predetermined value or more is applied because the rotary crushing unit 4 cannot rotate during crushing of the hard material, the motor may be controlled to reversely drive. By changing the direction in which the force is applied by reverse driving, the load can be reduced and the hard material can be crushed.

  By removing the crushing chamber 10, the scissor processing apparatus 100 according to the present embodiment integrates the crushing shaft 2, the crushing arm unit 3, the rotating crushing unit 4, the startup crushing unit 6, and the turntable 9 in the crushing chamber 10. These can be washed because they can be removed.

  Since the crushing chamber 10 is made of a resin material, it is light and easy to remove. Further, even when the removed crushing chamber 10 is placed on the sink 102, the sink 102 is not damaged. Note that the crushing chamber 10 may be provided with an impact absorbing member such as a rubber material in case of a fall or the like.

  The cocoon treatment apparatus 100 according to the present embodiment is capable of crushing mashes of various sizes while stirring efficiently by simplifying the shape of the rotary crushing unit 4 and devising the arrangement of parts in the crushing chamber 10. It was realized. The conventional hammer mill-type soot treating apparatus requires a rotational speed of about 2000 rpm and has to be provided with a vibration isolation structure. However, the soot treating apparatus 100 according to the present embodiment suppresses the rotational speed to about 700 rpm and prevents the anti-vibration structure. The vibration structure can be omitted. Thereby, the scissor processing apparatus 100 realized the reduction in the number of parts and low-cost manufacturing.

  The rotary crushing part 4 is configured to extend downward from the end of the crushing arm part 3, but the rotary crushing part 4 may be configured to extend upward or vertically from the crushing arm part 3. The extending directions of the two rotary crushing parts 4 may be different from each other. For example, when the rotary crushing portion 4 extends in the vertical direction, the vertical contact point with the crushed material at the time of crushing can be increased, so that the crushing efficiency can be increased.

  Although the two rotary crushing parts 4 were provided, it is not restricted to this. One or more rotary crushing units 4 may be provided, and the crushing efficiency increases as the number of the rotary crushing units 4 increases, but the part cost also increases. In addition, the form which a part of rotation crushing part 4 protrudes outside the crushing chamber 10 may be sufficient. For example, a form in which a part of the rotary crushing portion 4 protrudes to the outside of the bottom surface 10a may be used.

  Although the cross-sectional shape of the two rotary crushing parts 4 was made into the trapezoid of the same direction, it is not restricted to this. As long as the crushed material can be crushed, it may be a trapezoid in the opposite direction or may have another shape such as a rectangle. Moreover, in the case of the some rotation crushing part 4, each rotation crushing part 4 may have a different direction, a shape, and length.

  Although the protrusion part 5 and the raising crushing part 6 were provided in three places at intervals of 120 degrees, it is not restricted to this. It is preferable to provide at least one protrusion 5. When providing the protrusion part 5 in multiple places, it is preferable to provide at equal intervals. However, it is good also as a structure which abbreviate | omits the protrusion part 5 and crushes soot only with the rotary crushing part 4 and the starting crushing part 6. FIG. Moreover, when providing the protrusion part 5 at least one place, although it is preferable to provide the start crushing part 6 one or more places, you may abbreviate | omit. Further, as described above, the cross-sectional shapes of the protruding portion 5 and the rising crushing portion 6 are not limited to triangles and trapezoids as long as they can crush the ridges in cooperation with the rotary crushing portion 4. It may be square.

  The present invention is extremely suitable when applied to equipment such as a basket processing device installed in a kitchen sink of a building such as a general household or a restaurant.
