In a conventional granulating apparatus (for example, refer to Patent Document 1), a predetermined amount of raw material is supplied into a processing tank, a lid of the processing tank is closed, and a blade body and a rotary blade body provided in the processing tank are rotated. The raw material is crushed and sprinkled to cool and granulate.
JP-A-48-64552

  By the way, in an actual work site using the granulation apparatus as described above, in order to improve the efficiency of the granulation process, the blade body and the rotary blade body are rotated while the lid of the treatment tank is opened, and the raw materials are successively supplied thereto. And put it in. The raw material is repeatedly crushed, reduced in volume, and charged, and efficiently processed in large quantities. However, since the raw materials are manually input, the amount of the raw materials to be input is not constant, and there is a problem that the quality of the granulated product varies.

  An object of the present invention is to obtain a granulation apparatus that can improve the efficiency of the granulation treatment and can make the quality of the granulated product uniform, in consideration of the above facts.

  The granulation apparatus according to the invention described in claim 1 is provided above the processing tank, and communicates with the apparatus main body for crushing the raw material supplied into the processing tank and forming it into granules. It has a hopper in which the raw material is supplied, and a pushing means for pushing the raw material in the hopper into the treatment tank.

  In the granulating apparatus according to claim 1, a raw material (for example, a used synthetic resin film) supplied into the hopper is supplied into a treatment tank provided below the hopper and communicated with the hopper. (Flow down). The raw material supplied into the treatment tank is crushed by the apparatus main body and formed into a granular shape. For this reason, for example, if the raw material is fully supplied into the hopper and then the device body is operated, a certain amount of the raw material supplied will be crushed and granulated. Can be. And since the quantity of the raw material which can be supplied to a processing tank with one supply operation | work can be increased only by the volume of a hopper, the efficiency of a granulation process can be improved. Furthermore, since it has pushing means for pushing the raw material in the hopper into the treatment tank, even if the raw materials supplied into the hopper are entangled with each other and do not flow down into the treatment tank (so-called bridge occurs) The bridge can be eliminated satisfactorily.

  The granulation apparatus according to the invention described in claim 2 is configured by separating the apparatus main body for crushing the raw material supplied into the processing tank and forming it into a granular form, and the apparatus main body, and the raw material is contained inside A plurality of hoppers that are supplied and communicated with the inside of the processing tank in a state of being disposed above the processing tank, and a plurality of the hoppers are supported so as to be relatively movable with respect to the processing tank. Support means capable of moving one of the hoppers arbitrarily selected among the hoppers above the processing tank by the relative movement.

  In the granulation apparatus according to claim 2, when one hopper arbitrarily selected from the plurality of hoppers is moved above the processing tank, the inside of the hopper communicates with the processing tank. Thereby, the raw material in this hopper can be supplied (flowed down) into the treatment tank. The raw material supplied into the treatment tank is crushed by the apparatus main body and formed into a granular shape. For this reason, for example, if the apparatus main body is operated by moving the hopper supplied with the full raw material to the upper side of the processing tank, the fixed amount of the raw material supplied to the full is crushed and granulated. Therefore, the quality of the granulated product can be made uniform. And since the quantity of the raw material which can be supplied to a processing tank by one supply operation | work can be increased by the volume of a hopper, the efficiency of a granulation process can be improved. Furthermore, since a plurality of such hoppers are provided, raw materials can be supplied to other hoppers during the granulation process by one hopper. Therefore, since a granulation process can be performed efficiently and continuously by a plurality of hoppers, the efficiency of the granulation process can be further improved.

  The granulating apparatus according to a third aspect of the present invention is the granulating apparatus according to the first or second aspect, wherein the support means closes the communication port of the hopper into the treatment tank and The blockage is released in a state where a hopper is disposed above the processing tank.

  In the granulating apparatus according to the third aspect, the communication port of the hopper into the treatment tank is closed by the support means. When the hopper is moved above the treatment tank, the communication port is closed by the support means (the communication opening is opened), and the inside of the hopper communicates with the treatment tank. As described above, since the communication port of the hopper is opened and closed by the support means that supports the hopper so as to be relatively movable with respect to the processing tank, the apparatus can be configured simply.

  The granulating apparatus according to the invention described in claim 4 is the granulating apparatus according to claim 2 or claim 3, wherein the raw material in the hopper arranged above the processing tank is fed into the processing tank. It has the pushing means to push in, It is characterized by the above-mentioned.

  In the granulating apparatus according to claim 4, when the raw materials in the hopper are intertwined with each other and do not flow down into the processing tank in a state where the hopper is arranged above the processing tank (so-called bridge occurs). However, the raw material in the hopper can be forced into the treatment tank by the pushing means. Therefore, the bridge can be solved satisfactorily.

  The granulating apparatus according to the invention described in claim 5 is the granulating apparatus according to claim 1 or 4, wherein the pushing means descends the hopper by its own weight, thereby the raw material in the hopper. And a driving source for raising the lowered pressing plate.

  In the granulating apparatus according to claim 5, when the pressing plate descends in the hopper due to its own weight, the raw material in the hopper is pushed into the processing tank. Thereby, it is possible to prevent the so-called bridge from occurring. Moreover, a press plate can be raised by operating a drive source. Therefore, the pushing means can be made simple.

  As described above, in the granulation apparatus according to the present invention, the efficiency of the granulation treatment can be improved and the quality of the granulated product can be made uniform.

The rotary blade 34 is formed in a long plate shape, and the rotary shaft 20 is inserted into a cylindrical connecting portion provided at the center in the longitudinal direction and is keyed. For this reason, the rotary blade body 34 rotates integrally with the rotary shaft 20 and the blade body 32. In the first embodiment, the rotary blade 34 is screwed to the blade body 32 and is integrally formed. However, these may be formed separately.

  Both end portions in the longitudinal direction of the rotary blade 34 are arranged close to the inner wall of the processing tank 18, and turn with a slight gap secured between the inner wall of the processing tank 18.

  A plurality of fixed blade bodies 36 are fixed to the inner wall of the processing tank 18. These fixed blades 36 are disposed in the vicinity of the upper side of the turning trajectory at both ends in the longitudinal direction of the rotary blade 34, and face the turning trajectory with a predetermined gap. The gap can be adjusted by changing the thickness of the collar 38 disposed between the bottom wall of the processing tank 18 and the blade body 32.

  A cutting blade is formed on the end edge of the rotary blade body 34 in the rotational direction front side (arrow A direction side in FIG. 2), and the fixed blade body 36 has a rear side in the rotational direction of the rotary blade body 34 (see FIG. A cutting blade is formed at the edge of the opposite side of the arrow 2 in FIG.

  On the other hand, a supply pipe 40 for supplying liquid or powder into the processing tank 18 is connected to the upper side of the side wall of the processing tank 18. The supply pipe 40 has one end (not shown) connected to a liquid or powder supply source (not shown), and the electromagnetic valve 42 attached to the other end (the treatment tank 18 side) is opened to open the treatment tank 18. Liquid or powder is supplied inside. For example, water is used as the liquid, and a color pigment is used as the powder. In the first embodiment, a case where water is used will be described.

  Further, an exhaust pipe 44 is attached to the upper side of the side wall of the processing tank 18. One end of the exhaust pipe 44 (not shown) is connected to a suction blower (not shown). When the suction blower is operated, the air in the processing tank 18 is exhausted to the outside of the apparatus via the exhaust pipe 44. It is like that.

  Further, a plate-like shutter 46 for closing the upper end opening of the processing tank 18 is provided on the upper part of the processing tank 18. The shutter 46 is slid in the radial direction with respect to the processing tank 18 by a shutter motor 48 attached to the side wall of the processing tank 18, and the upper end opening of the processing tank 18 is opened and closed by the sliding of the shutter 46. Is done.

  Further, a temperature sensor 50 for detecting the temperature in the processing tank 18 is attached to the side wall of the processing tank 18. The temperature sensor 50 is electrically connected to a control device (not shown). This control device is electrically connected to the electromagnetic valve 42 described above, and opens the electromagnetic valve 42 for a predetermined time when the temperature sensor 50 detects that the inside of the processing tank 18 has reached a predetermined temperature. It has become. Thereby, a certain amount of water is supplied (sprayed) from the supply pipe 40 into the treatment tank 18.

  Furthermore, a bowl-shaped discharge port 52 for discharging the granulated material granulated in the processing tank 18 to the outside of the apparatus is attached to the lower side of the side wall of the processing tank 18. The inside of the processing tank 18 communicates with the outside of the apparatus. The discharge port 52 is opened and closed by a discharge valve 54 that is rotated by a motor (not shown).

  On the other hand, a hopper 56 is provided above the processing tank 18 described above. The hopper 56 is formed in a cylindrical shape having a larger diameter than the processing tank 18 and long in the axial direction, and is disposed coaxially with respect to the processing tank 18. The lower end side of the hopper 56 is drawn into a funnel shape, and the lower end portion of the hopper 56 is reduced in diameter to the same extent as the diameter of the processing bath 18, and a flange portion 18 </ b> A provided at the upper end portion of the processing bath 18. Is bound to. Accordingly, the hopper 56 and the processing tank 18 are integrally connected, and the hopper 56 is supported by the frame 14 via the processing tank 18 and the support member 16. Moreover, the lower end part of the hopper 56 is opening, and the inside of the hopper 56 and the inside of the processing tank 18 are connected via the said opening part.

  Further, the upper end portion of the hopper 56 is closed by an upper wall 56A, and a weight motor 58 as a drive source is attached to the upper surface of the upper wall 56A. The weight motor 58 is arranged with the output shaft protruding in the radial direction of the hopper 56, and a spool 60 is attached to the output shaft. One end of the rope 62 in the longitudinal direction is locked to the spool 60, and when the weight motor 58 rotates the output shaft (spool 60) to one side around the axis, the rope 62 moves from the one end in the longitudinal direction to the spool 60. It is wound up. When the weight motor 58 rotates the output shaft (spool 60) to the other around the axis, the rope 62 is pulled out from the spool 60.

  The other end side in the longitudinal direction of the rope 62 is inserted into a hopper 56 through a through hole formed in the central portion of the upper wall 56A. A pressing plate 64 formed in a disk shape is provided in the hopper 56, and the other longitudinal end portion of the rope 62 inserted into the hopper 56 is locked to the central portion of the upper surface of the pressing plate 64. ing. Thereby, the pressing plate 64 is suspended in the hopper 56 in a state of being substantially coaxial with the hopper 56.

  The outer diameter dimension of the pressing plate 64 is slightly smaller than the inner diameter dimension of the hopper 56, and the pressing plate 64 can move relative to the hopper 56 in the vertical direction. For this reason, when the weight motor 58 rotates the output shaft (spool 60) to the other around the axis and the rope 62 is pulled out of the spool 60, the pressing plate 64 descends in the hopper 56 by its own weight. As a result, the pressing plate 64 is lowered to the lower limit position indicated by the two-dot chain line in FIG.

  Further, when the weight motor 58 rotates the output shaft (spool 60) to one side around the axis and the rope 62 is wound around the spool 60 in a state where the pressing plate 64 is lowered to the lower limit position as described above, the pressing plate 64 is pulled by the rope 62 and moves up in the hopper 56, and is moved up to the upper limit position shown by the solid line in FIG. Note that the pressing plate 64 is normally held at the upper limit position.

  On the other hand, a raw material inlet 66 is formed on the upper side of the side wall of the hopper 56. This input port 66 is for supplying (inputting) the raw material of the granulated material to be granulated in the processing tank 18 into the hopper 56, and below the pressing plate 64 disposed at the upper limit position. It is provided and opened and closed by a door 68 that is rotatably attached to the side wall of the hopper 56.

  Next, the operation of the first embodiment will be described.

  When using the granulating apparatus 10 having the above-described configuration, the upper end opening of the processing tank 18 is first closed by the shutter 46, the door 68 of the raw material charging port 66 of the hopper 56 is opened, and the inside of the hopper 56 is opened from the raw material charging port 66. A raw material (for example, a used polyethylene film, etc.) is fully charged to close the door 68 of the raw material inlet 66.

  Next, the motor 24 is operated to rotate the blade body 32 and the rotary blade body 34. In this state, when the shutter 46 is slid by the shutter motor 48 and the upper end opening of the processing tank 18 is opened, the raw material in the hopper 56 flows down into the processing tank 18. Since the volume of the hopper 56 is sufficiently larger than the volume of the processing tank 18, a part of the raw material supplied into the hopper 56 flows down into the processing tank 18 to fill the processing tank 18. A part of the raw material remains in the hopper 56.

  The raw material that has flowed into the treatment tank 18 is caught on the front edge of the rotary blade 34 in the rotation direction, and is moved to the longitudinal end portion side (the inner wall side of the treatment tank 18) of the rotary blade 34 by the centrifugal force accompanying the rotation. Is done. The raw material moved to the inner wall side of the processing tank 18 is cut and crushed between the blade edge of the rotary blade body 34 and the blade edge of the fixed blade body 36 and is also lifted upward by the blade body 32 to cut as described above. Repeated crushing. Thereby, the raw material is cut and crushed into pieces having a size that fits in the gap between the rotary blade body 34 and the fixed blade body 36, and the volume is reduced to about one-tenth of the volume.

  Next, when the weight motor 58 is operated and the spool 60 is rotated around the axis to the other side, the rope 62 is pulled out from the spool 60 and the pressing plate 64 is lowered in the hopper 56 by its own weight. Thereby, a part of the raw material left in the hopper 56 is forced into the processing tank 18. For this reason, even if part of the raw material left in the hopper 56 is entangled with each other in the vicinity of the lower end opening of the hopper 56 and does not naturally flow down into the treatment tank 18 (so-called bridge occurs). The bridge can be eliminated and the raw material can be supplied into the processing tank 18.

  The raw material newly supplied into the treatment tank 18 is cut and crushed into pieces that meet the gap between the rotary blade body 34 and the fixed blade body 36, and the pieces that have been cut and crushed first are the same as described above. Mixed with. These crushed pieces are repeatedly raised upward by the blade body 32, the crushed pieces collide with each other, and the surface of each crushed piece is semi-gelled by the frictional heat. Thereby, each crushing piece is shape | molded into the roundish granule as a whole.

  When the inside of the processing tank 18 reaches a predetermined temperature (for example, 100 ° C. to 120 ° C.) due to friction between the crushed pieces as described above, the temperature sensor 50 is activated to open the electromagnetic valve 42, and the processing pipe 18 is opened from the supply pipe 40. A certain amount of water is supplied (sprayed) into 18. Thereby, the surface of the crushed pieces semi-gelled as described above is rapidly cooled, and fusion between the crushed pieces is prevented. During this rapid cooling, water vapor is generated in the processing tank 18, and the water vapor is discharged from the processing tank 18 to the outside through the exhaust pipe 44 by the operation of a suction blower (not shown). The granulated material solidified by the rapid cooling is discharged to the outside of the processing tank 18 through the discharge port 52 when the discharge valve 54 is opened by a motor (not shown). This completes the granulation process.

  By the way, as explained in the section of the background art, in an actual work site where a conventional granulating apparatus is used, in order to improve the efficiency of the granulating process, the blade body and the rotary blade body with the lid of the processing tank being opened. The raw material is put into it one after another. In this case, since the raw material is manually input into the processing tank where the rotary blade rotates at high speed, it is necessary to ensure safety at the time of input.

  Further, in the case of the above-described working method, as described in the background art section, there is a problem that the quality of the granulated product varies because the amount of the raw material charged into the treatment tank is not constant. That is, if the raw material is quickly and rapidly put into the processing tank, it takes time until the inside of the processing tank reaches a predetermined temperature. In the meantime, the raw material is finely crushed and reduced in volume, and then a large amount of raw material is added, and then a certain amount of water is supplied. Conversely, if the raw materials are slowly added little by little, it will not take much time until the inside of the treatment tank reaches a predetermined temperature, and a certain amount of water will be supplied in a state where only a small amount of raw materials are put. Therefore, the ratio of the amount of water supply to the amount of the raw material becomes non-uniform, and the degree of cooling and the particle size formation become non-uniform. As a result, the quality of the granulated product (bulk specific gravity, etc.) becomes non-uniform, causing a problem of adversely affecting the selling price. In an actual work site, in order to make the ratio of the amount of water supply to the amount of raw material uniform, water is manually supplied into the treatment tank, but this work requires skill. There's a problem.

  On the other hand, in the granulation apparatus 10 according to the first embodiment, as described above, the apparatus main body 12 is operated in a state where the raw material is fully supplied into the hopper 56, and a certain amount supplied to the full capacity. The raw material is crushed and granulated in the treatment tank 18. For this reason, while being able to make constant time until the fragment (granulated material) crushed in the processing tank 18 becomes predetermined | prescribed temperature, a fixed quantity of water is supplied with respect to a fixed quantity of granulated substance. Can be supplied. Therefore, the degree of cooling and the granulation degree of the granulated product can be made uniform, and thereby the quality of the granulated product can be made uniform.

  Moreover, in the granulation apparatus 10 according to the first embodiment, the amount of the raw material that can be supplied to the treatment tank 18 by a single supply operation can be increased by the volume of the hopper 56. A large amount of raw materials can be granulated at once, and the efficiency of the granulation process can be improved. Therefore, unlike the conventional case, in order to improve the efficiency of the granulation treatment, it is not necessary to put the raw material into the treatment tank 18 while the rotary blade 34 or the like is rotating, thereby ensuring safety. be able to.

  Furthermore, the granulating apparatus 10 according to the first embodiment includes a shutter 46 that opens and closes the upper end opening of the processing tank 18. While the shutter 46 is closed, the raw material is charged into the hopper 56. Then, after rotating the blade body 32 and the rotary blade body 34 by the motor 24, the shutter 46 is opened. For this reason, since the raw material is supplied into the processing tank 18 after the rotational speed of the motor 24 (the blade body 32 and the rotary blade body 34) is stabilized, the motor 24 is prevented or suppressed from being overloaded. Can do.

  In the granulating apparatus 10 according to the first embodiment, the weight motor 58 is operated to lower the pressing plate 64 by its own weight, thereby pushing the raw material in the hopper 56 into the processing tank 18. The occurrence of bridging can be prevented with a simple configuration.

In the first embodiment, the hopper 56 is formed in a cylindrical shape. However, the present invention is not limited to this, and the shape of the hopper can be changed as appropriate. This also applies to the second embodiment of the present invention described below.
<Second Embodiment>
Next, a second embodiment of the present invention will be described. In addition, about the structure and effect | action fundamentally similar to the said 1st Embodiment, the same sign as the said 1st Embodiment is provided, and the description is abbreviate | omitted.

  FIG. 3 shows a partial cross-sectional view of a granulating apparatus 70 according to the second embodiment of the present invention as viewed from the side. The granulating apparatus 70 has basically the same configuration as the granulating apparatus 10 according to the first embodiment. However, the granulating apparatus 70 includes a plurality of (three in the second embodiment) hoppers 72 separated from the apparatus main body 12 instead of the hopper 56 according to the first embodiment. I have. These hoppers 72 are supported by a gantry 74 as support means.

  The gantry 74 includes a support plate 76 formed in a long plate shape. The support plate 76 is disposed on the upper side of the apparatus main body 12 in a state parallel to the floor surface 78 on which the granulation apparatus 70 is installed, and the lower surface of the middle portion in the longitudinal direction is provided at the upper end of the processing tank 18. The flange portion 18A is coupled. The support plate 76 is supported by a plurality of legs 80 provided between the floor surface 78 (only one leg 80 is shown in FIG. 3).

  On the other hand, the plurality of hoppers 72 described above are arranged side by side in the longitudinal direction above the support plate 76. In the second embodiment, the plurality of hoppers 72 are separated from each other. However, the hoppers 72 may be integrally connected.

  These hoppers 72 have basically the same configuration as the hopper 72 according to the first embodiment, but the upper wall 56A according to the first embodiment is omitted, and both upper and lower end portions are formed. It is open. A plurality of casters 82 are attached to the lower end side (drawn portion) of each hopper 72. The wheels of these casters 82 protrude slightly below the lower end of each hopper 72, and each hopper 72 is placed on the support plate 76 in a state where these wheels are in contact with the upper surface of the support plate 76. It is placed. Therefore, each hopper 72 can run on the support plate 76.

  A rail 84 is attached to the upper surface of the support plate 76 along its longitudinal direction. The rail 84 is adapted to guide the traveling direction of each hopper 72 by engaging with a caster 82 (wheel) of each hopper 72. As a result, each hopper 72 can travel in the longitudinal direction of the support plate 76 (see arrows B and C in FIG. 3) and can move relative to the apparatus main body 12. Thereby, in the second embodiment, one hopper 72 arbitrarily selected from the plurality of hoppers 72 can be moved above the processing tank 18.

  Further, a through hole 86 is formed in the support plate 76 at a position facing the processing tank 18. Therefore, in a state where one of the plurality of hoppers 72 is disposed above the processing tank 18, the inside of the hopper 72 communicates with the inside of the processing tank 18 through the through hole 86 ( (See the hopper 72 disposed in the center in FIG. 3). Further, in this state, the other two hoppers 72 are configured to block the lower end opening (communication port to the processing tank 18) by the support plate 76.

  On the other hand, a housing 88 for accommodating the pressing plate 64 is provided above the plurality of hoppers 72 and above the processing tank 18. The housing 88 is formed in a cylindrical shape having a short axial dimension, and is fixed to the gantry 74 via a support column (not shown) in a state of being coaxially disposed with respect to the processing tank 18. The inner diameter and the outer diameter of the housing 88 are formed to be equivalent to those of the hoppers 72. When any one of the hoppers 72 is disposed above the processing tank 18, the hopper 72 and the housing 88 are separated from each other. It is continuously integrated vertically.

  Further, the upper end portion of the housing 88 is closed by an upper wall 88A, and a weight motor 58 is attached to the upper portion of the upper wall 88A. The weight motor 58 is connected to the pressing plate 64 via the spool 60 and the rope 62 as in the first embodiment, and moves the pressing plate 64 down and up.

  Next, the operation of the second embodiment will be described.

  When using the granulating apparatus 70 having the above configuration, first, the upper end opening of the processing tank 18 is closed by the shutter 46, and at least one of the plurality of hoppers 72 is filled with the raw material. Then, any one hopper 72 filled with the raw material is moved upward of the processing tank 18. Thereby, the inside of the hopper 72 communicates with the inside of the processing tank 18 through the through hole 86 of the support plate 76, and the raw material in the hopper 72 flows down to the processing tank 18 side. However, the raw material that has flowed down is blocked by the shutter 46.

  Next, when the motor 24 is operated to rotate the blade body 32 and the rotary blade body 34 and then the shutter 46 is opened by the shutter motor 48, the raw material in the hopper 56 flows down into the processing tank 18. As a result, as in the first embodiment, the raw material that has flowed into the processing tank 18 is cut and crushed into pieces having a size that fits into the gap between the rotary blade body 34 and the fixed blade body 36, and the volume is reduced. The

  Next, when the weight motor 58 is operated to lower the pressing plate 64, the pressing plate 64 enters the hopper 72 disposed above the processing tank 18 and descends in the hopper 72. Thereby, like the said 1st Embodiment, all the raw materials in the hopper 56 are pushed in into the processing tank 18, and generation | occurrence | production of a bridge is prevented. And like the said 1st Embodiment, in the processing tank 18, cutting | disconnection crushing of a raw material and sprinkling cooling are performed, and the manufactured granulated material is discharged | emitted from the discharge port 52. FIG.

  As described above, in the second embodiment, as in the first embodiment, since a certain amount of raw material supplied in the hopper 72 is crushed and granulated, the quality of the granulated product is improved. While being able to make it uniform, the efficiency of a granulation process can be improved.
