Description

  The present invention relates to an organic waste supply apparatus that supplies organic waste to a predetermined supply destination.

As a conventional feeder of this type, for example, there is a quantitative feeder described in Patent Document 1. This metering feeder is installed at the entrance of a foreign matter separation device for removing foreign matter from organic waste, and a pair of rotating bodies (projection support) that rotate to feed the organic waste into this entrance. Body). Since organic waste is generally packaged and collected, a large number of protrusions for breaking the collection bag are integrally attached to each rotating body. As a result, the collection bag is broken when the organic waste passes between the rotating bodies, and the foreign matter separating apparatus can reliably remove the collection bag that is a foreign matter from the organic waste. .
JP 2002-177888 A

  However, the quantitative feeder described in Patent Document 1 has a problem in that foreign matter such as a collection bag broken by a large number of protrusions or a waste or vinyl string gets entangled with each rotating body. . Then, various foreign substances are further entangled due to the entangled collection bag and the like, and in the worst case, there is a situation in which the operation of the quantitative feeder is stopped due to the blockage between the rotating bodies. In order to prevent such a situation, it is necessary to set the driving torque of each rotating body high, but in this case, there is a problem that the energy consumed by the metering feeder increases.

  Then, this invention is made | formed in view of such a situation, and it aims at providing the organic waste supply apparatus which can supply the organic waste stably with low consumption energy.

  In order to achieve the above object, an organic waste supply apparatus according to the present invention is an organic waste supply apparatus that supplies organic waste to a predetermined supply destination, and has a separated portion that communicates with the supply destination. First and second introduction rollers that are arranged side by side and rotate in a direction in which the organic waste is introduced into the separated portion, and a first scraper that peels off the organic waste adhering to the peripheral surface of the first introduction roller And a second scraper that peels off the organic waste adhering to the peripheral surface of the second introduction roller, and a cutting blade is provided on the peripheral surface of the portion of the first introduction roller facing the first scraper. Is formed, and a second recess functioning as a cutting blade is formed on a peripheral surface of a portion of the second introduction roller facing the second scraper. .

  In this organic waste supply apparatus, the first and second introduction rollers arranged in parallel with a separation portion communicating with a predetermined supply destination rotate in a direction to introduce the organic waste into the separation portion. Thus, the supply of organic waste to a predetermined supply destination is achieved. At this time, foreign matter such as collection bags, waste cloths, vinyl strings, etc. are contained in organic waste, and even if these collection bags adhere to each introduction roller, a scraper is placed opposite each introduction roller. Therefore, the collection bag or the like attached to the peripheral surface of each introduction roller is peeled off by the scraper. Even if a collection bag or the like enters between the scraper and the peripheral surface of the introduction roller, a concave portion that functions as a cutting blade is formed on the peripheral surface of the portion facing each scraper of each introduction roller. The collection bag or the like is cut by the cooperation of the recess and the recess. In this way, it is possible to prevent the collection bag and the like from being entangled with each introduction roller, so that the organic waste contained in the collection bag does not block the separation part of the supply device or the lower part thereof, Stable quantitative supply is possible, and the driving torque of each introduction roller can be set low. Therefore, stable organic waste can be supplied with low energy consumption. Note that the term “organic waste” simply means organic waste in a state including foreign matter such as a collection bag, a waste, a vinyl string, and an empty can.

  In addition, a plurality of first recesses are formed around the axis of the first introduction roller on the peripheral surface of the portion of the first introduction roller facing the first scraper, and the second recess is defined as the second introduction roller. It is preferable that a plurality of rollers are formed around the axis of the second introduction roller on the peripheral surface of the portion of the roller facing the second scraper. Thereby, the concave portion that functions as a cutting blade is opposed to the scraper a plurality of times while the introduction roller rotates once. Therefore, it is possible to immediately cut the collection bag or the like that has entered between the scraper and the peripheral surface of the introduction roller.

  The first recess is a groove extending along the axial direction of the first introduction roller on the peripheral surface of the portion of the first introduction roller facing the first scraper, and the second recess is In the peripheral surface of the portion of the second introduction roller facing the second scraper, a groove extending along the axial direction of the second introduction roller is preferable. As a result, on the peripheral surface of the portion of the introduction roller facing the scraper, the groove functioning as a cutting blade is continuous along the axial direction of the introduction roller. By adopting such a configuration, the recovery bag or the like can be more reliably cut by the cooperation of the scraper and the recess.

  Further, the groove formed in the first introduction roller extends in a direction inclined with respect to the axial direction of the first introduction roller, and the groove formed in the second introduction roller is the second introduction roller. It preferably extends in a direction inclined with respect to the axial direction. As a result, the recovery bag or the like pressed against the peripheral surface of the introduction roller by the scraper is pressed with a groove functioning as a cutting blade at an angle, and the recovery bag or the like that enters between the peripheral surface of the scraper and the introduction roller is It will be cut continuously little by little. Therefore, it is possible to reduce the load generated on the introduction roller by cutting, and it is possible to set the driving torque of the introduction roller to be lower. Furthermore, since the load generated on the grooves and the scraper due to the cutting is reduced, it is possible to prevent the breakage and extend the life.

  The first claw member is provided so as to protrude from the peripheral surface of the first introduction roller, and is provided so as to protrude from the peripheral surface of the second introduction roller. It is preferable to include a second claw member to be hooked. As a result, the organic waste can be reliably introduced into the space between the first and second introduction rollers, and the organic waste can be quantitatively supplied to a predetermined supply destination. Moreover, when the organic waste is packaged, the claw member can break the collection bag.

  A plurality of first claw members are provided along the axial direction of the first introduction roller, and the second claw members are alternately staggered with the first claw member along the axial direction of the second introduction roller. A plurality of first claw members and second claw members that are provided adjacent to each other are preferably separated in the axial direction of the first and second introduction rollers. With such a configuration, for example, even if a metal foreign matter such as an empty can is contained in the organic waste, this kind of foreign matter is between the first claw member and the second claw member adjacent to each other. Will pass. In this way, metal foreign objects can be passed, so that the claw members and the like can be prevented from being damaged and the service life can be extended. In addition, compared to the case where metal foreign objects are crushed or cut, the introduction roller It is also possible to set a lower driving torque.

  Further, it is preferable that the first scraper is movable forward and backward with respect to the circumferential surface of the first introduction roller, and the second scraper is movable forward and backward with respect to the circumferential surface of the second introduction roller. This makes it possible to adjust the gap between the scraper and the peripheral surface of the introduction roller in accordance with the thickness of the collection bag or the like. Furthermore, if the scraper is deformed due to long-term use, for example, the position of the scraper with respect to the peripheral surface of the introduction roller is adjusted as appropriate, and the cutting function of the collection bag or the like by the cooperation of the scraper and the recess is performed. Can be maintained.

  According to the organic waste supply apparatus according to the present invention, it is possible to stably supply organic waste with low energy consumption.

  Hereinafter, a preferred embodiment of an organic waste supply apparatus according to the present invention will be described in detail with reference to the drawings. As shown in FIG. 1, the organic waste supply apparatus 10 is configured to dispose organic waste such as raw garbage mainly packed in a collection bag to the separation chamber (predetermined supply destination) 2 of the separation apparatus 1. It is a device that supplies things.

  Prior to the description of the organic waste supply apparatus 10, the separation apparatus 1 will be briefly described. The separation device 1 is a device that separates and removes foreign matters such as collection bags, wastes, vinyl strings, empty cans, and the like from the organic waste supplied by the supply device 10. As shown in FIGS. 1 and 2, the separation chamber 2 of the separation device 1 has a cylindrical shape, and at one end thereof, an input port 2 a that opens upward is provided. The lower peripheral wall 2b of the separation chamber 2 is provided with a large number of pores (not shown). In the separation chamber 2 formed in this way, a rotating shaft 4 that is rotationally driven in the direction of arrow A by a drive motor 3 is spanned, and a rotating plate 5 is attached to the rotating shaft 4 every 90 degrees. ing. A rubber plate 6 is attached to the tip of each rotary plate 5, and when the rotary shaft 4 rotates, each rubber plate 6 slides on the inner surface of the lower peripheral wall 2b.

  In the separation chamber 2 configured as described above, the organic waste sent from the supply port 2 a by the supply device 10 is rotated in the separation chamber 2 by the respective rotating plates 5. Thereby, the organic waste from which the foreign matter has been removed is pulverized into a slurry, and is discharged out of the separation chamber 2 from the pores of the lower peripheral wall 2b. On the other hand, foreign matter such as a collection bag contained in the organic waste is pumped to the other end side of the separation chamber 2 by the three-month guide blade 2c and the airflow in the upper space in the separation chamber 2.

  As shown in FIG. 1, foreign matter such as collection bags sorted in the separation chamber 2 is transferred to the foreign matter discharge port 7 and further separated as necessary, and disposed of by landfill or incineration. On the other hand, the slurry-like organic waste discharged from the separation chamber 2 is transferred by a slurry transfer machine 8 installed below the separation chamber 2 and is transferred to a slurry tank (not shown) via a slurry discharge port 9. Stored. The organic waste from which foreign substances have been removed in this manner is used to recover biogas (methane gas), and the organic waste is recycled.

  Next, the organic waste supply apparatus 10 will be described in detail. As shown in FIG. 2, the supply device 10 has a housing 11 fixed to the separation chamber 2 so as to cover the insertion port 2a, and the upper end portion of the housing 11 is mainly packed in a collection bag. A receiving hopper 12 into which organic waste such as raw garbage is put is attached. A first introduction roller 13 and a second introduction roller 14 arranged in parallel with a separation portion S communicating with the input port 2a face the opening at the lower end of the receiving hopper 12.

  As shown in FIG. 3, a plurality of first introduction rollers 13 are fixed to a first rotation shaft 15 that is pivotally supported by the housing 11 on the axis L1. On the other hand, a plurality of second introduction rollers 14 are fixed to a second rotating shaft 16 that is pivotally supported by the housing 11 on an axis L2 parallel to the axis L1. As shown in FIG. 2, since the cross-sectional shape of the shaft hole of the first introduction roller 13 and the mounting portion 15a of the first rotation shaft 15 is a regular hexagon, the first introduction roller 13 and the first rotation shaft Integral rotation with 15 is ensured. Similarly, since the cross-sectional shape of the shaft hole of the second introduction roller 14 and the attachment portion 16a of the second rotation shaft 16 is a regular hexagon, the second introduction roller 14 and the second rotation shaft 16 are integrated. Rotation is ensured.

  As shown in FIG. 3, geared motors 17 fixed to the side walls of the outer side of the housing 11 are connected to the rotary shafts 15 and 16, respectively. As a result, the first introduction roller 13 rotates in the direction of arrow B, and the second introduction roller 14 rotates in the direction of arrow C (see FIG. 2). As described above, the introduction rollers 13 and 14 rotate in a direction in which the organic waste in the receiving hopper 12 is introduced into the separation portion S, so that the organic waste is supplied to the separation chamber 2 through the input port 2a. Supply is achieved.

  Further, four first claw members 19 (shaded portions in FIG. 3) and four spacers 20 are alternately arranged on the first rotation shaft 15 in the direction of the axis L1 with the first introduction roller 13 interposed therebetween. It is fixed. On the other hand, on the second rotating shaft 16, four second claw members 21 (shaded portions in FIG. 3) and four spacers 20 are alternately arranged in the direction of the axis L2 with the second introduction roller 14 interposed therebetween. It is fixed.

  As shown in FIG. 2, the first claw member 19 has three claw portions 19a protruding from the peripheral surface of the first introduction roller 13 every 120 degrees with the axis L1 as the center. The tip of the claw portion 19a is curved in the rotation direction (arrow B direction) of the first claw member 19. On the other hand, the second claw member 21 has three claw portions 21a protruding from the peripheral surface of the second introduction roller 14 every 120 degrees centering on the axis L2. The tip of the claw portion 21a is curved in the rotation direction (arrow C direction) of the second claw member 21. In addition, the quantity of each claw member 19 and 21 in each rotating shaft 15 and 16 and the quantity of the claw parts 19a and 21a in each claw member 19 and 21 are not limited to the above-mentioned quantity.

  As shown in FIG. 4, the organic waste G in the receiving hopper 12 is hooked by the first and second claw members 19, 21 formed in this way, and the separation between the introduction rollers 13, 14 is performed. The organic waste G can be reliably introduced into the portion S, and the organic waste G can be quantitatively supplied to the separation chamber 2. Moreover, by providing the first and second claw members 19 and 21, the collection bag containing the organic waste G can be broken and supplied to the separation chamber 2. In the separation device 1, It is possible to reliably remove a collection bag or the like that is a foreign substance from the organic waste G.

  And as shown in FIG. 3, each claw member 19 of the 1st rotating shaft 15 and each claw member 21 of the 2nd rotating shaft 16 are arrange | positioned alternately, and the 1st claw member 19 is 2nd. The second claw members 21 face the spacers 20 of the first rotation shaft 15, respectively. As a result, the first claw member 19 and the second claw member 21 adjacent to each other are separated from each other in the direction of the axis L1 (L2).

  With such a configuration, for example, even if a metal foreign matter such as an empty can is included in the organic waste G, this kind of foreign matter is adjacent to the first claw member 19 and the second claw member 21 that are adjacent to each other. Will pass between. As described above, since the metallic foreign matter can be passed, it is possible to prevent the claw members 19 and 21 from being damaged and to prolong the service life. In addition, the driving torque of the first and second rotating shafts 15 and 16 can be set lower than in the case where metal foreign objects are crushed or cut.

  Here, FIG. 5 is an array diagram showing a fixed state of the first claw member 19 with respect to the first rotating shaft 15 and a fixed state of the second claw member 21 with respect to the second rotating shaft 16. It is assumed that the rotary shafts 15 and 16 are fixed in the order of the lower stage. As shown in the drawing, each of the first claw members 19 is formed with a shaft hole having a regular hexagonal cross-sectional shape with a phase shifted by 30 degrees about the axis L1. The member 19 is fixed to the first rotating shaft 15 in a state where the phase is shifted by 30 degrees. Similarly, a shaft hole having a regular hexagonal cross section is formed in each of the second claw members 21 with a phase difference of 30 degrees about the axis L2, so that each claw member 21 has 30 It is fixed to the second rotating shaft 16 with its phase shifted by degrees.

  Therefore, the timing at which the organic waste G is hooked by the claw portions 19a and 21a of the claw members 19 and 21 is shifted, and the load generated on the first and second rotating shafts 15 and 16 is averaged. Therefore, the driving torque of the first and second rotating shafts 15 and 16 can be set low. In addition, uneven supply of the organic waste G to the separation chamber 2 is suppressed, and further quantitative supply is promoted. Further, since the cross-sectional shape of the shaft holes of the first and second claw members 19 and 21 is a regular hexagonal shape, the first claw member 19 and the first claw member 19 and the second claw member 19 and the second introduction roller 13 and 14 are similar to the first and second introduction rollers 13 and 14. The integral rotation with the first rotation shaft 15 and the integral rotation between the second claw member 21 and the second rotation shaft 16 are ensured.

  Further, as shown in FIG. 2, the housing 11 includes a first scraper 23 that faces each introduction roller 13 below each of the first introduction rollers 13 and a bottom of each second introduction roller 14. A second scraper 24 facing each introduction roller 14 is attached. The first scraper 23 is fixed by a fixing bolt 25 with a minute gap of about 10 μm from the peripheral surface of the first introduction roller 13 with the tip thereof tilted toward the separation portion S side. Similarly, the second scraper 24 is fixed by a fixing bolt 25 with a minute gap of about 10 μm from the peripheral surface of the second introduction roller 14 with the tip thereof tilted toward the separating portion S side. If the adjusting bolt 26 is rotated in a state where the fixing bolt 25 is loosened, the first scraper 23 is against the peripheral surface of the first introduction roller 13 and the second scraper 24 is the second introduction. The roller 14 can be moved back and forth with respect to the peripheral surface.

  As shown in FIG. 3, a large number of grooves (first recesses) 13a extending around the axis L1 are formed on the peripheral surface of the first introduction roller 13 in a direction inclined with respect to the direction of the axis L1. ing. In these grooves 13a, an edge portion formed by the peripheral surface of the first introduction roller 13 functions as a cutting blade. On the other hand, on the peripheral surface of the second introduction roller 14, a number of grooves (second recesses) 14a extending in a direction inclined with respect to the direction of the axis L2 are formed around the axis L2. Also in these grooves 14a, an edge portion formed by the peripheral surface of the second introduction roller 14 functions as a cutting blade.

  As shown in FIG. 6, the above-described first and second scrapers 23 and 24 are used to collect organic waste containing foreign matter such as collection bags, wastes, and vinyl strings attached to the peripheral surfaces of the introduction rollers 13 and 14, respectively. G will be stripped off. In addition, as shown in FIG. 7, the first scraper 23 and the groove 13 a of the first introduction roller 13 cooperate with each other to enter between the first scraper 23 and the peripheral surface of the first introduction roller 13. The collection bag will be cut. Similarly, the collection bag or the like that has entered between the second scraper 24 and the peripheral surface of the second introduction roller 14 is cut by the cooperation of the second scraper 24 and the groove 14a of the second introduction roller 14. Will be. In this way, it is possible to prevent the collection bag and the like from being entangled with the first and second introduction rollers 13 and 14, so that the driving torque of the first and second rotary shafts 15 and 16 is set low. Is possible. Therefore, the organic waste G can be stably supplied with low energy consumption.

  In each of the introduction rollers 13 and 14, a plurality of grooves 13a are formed around the axis L1, and a plurality of grooves 14a are formed around the axis L2 (see FIG. 3). As a result, the first scraper 23 is opposed to the groove 13a that functions as a cutting blade a plurality of times while the first rotary shaft 15 makes one rotation, while the second scraper 24 has a second rotation. While the shaft 16 makes one rotation, the groove 14a that functions as a cutting blade faces a plurality of times. Therefore, the recovery bag or the like that has entered between the first scraper 23 and the peripheral surface of the first introduction roller 13 or between the second scraper 24 and the peripheral surface of the second introduction roller 14 is immediately cut. It becomes possible.

  Moreover, each groove | channel 13a, 14a is extended in the direction which inclines with respect to the axis line L1, L2 direction (refer FIG. 3). As a result, the groove 13a continues along the axis L1 direction at the portion facing the first scraper 23, and the groove 14a continues along the axis L2 direction at the portion facing the second scraper 24. Become. Therefore, the cutting of the collection bag or the like by the cooperation of the first scraper 23 and the groove 13a of the first introduction roller 13 and the collection by the cooperation of the second scraper 24 and the groove 14a of the second introduction roller 14 are performed. A bag or the like can be more reliably cut.

  In addition, a groove 13a that functions as a cutting blade is pressed against the collection bag or the like pressed against the peripheral surface of the first introduction roller 13 by the first scraper 23 at an angle. Similarly, a groove 14a that functions as a cutting blade is pressed at an angle to the collection bag or the like pressed against the peripheral surface of the second introduction roller 14 by the second scraper 24. As a result, the collection bag or the like that has entered between the first scraper 23 and the peripheral surface of the first introduction roller 13 or between the second scraper 24 and the peripheral surface of the second introduction roller 14 is slightly It will be cut continuously. Therefore, the load generated on the first and second rotary shafts 15 and 16 due to the cutting can be reduced, and the drive torque of each rotary shaft 15 and 16 can be set lower. Further, since the load generated in the grooves 13a and 14a and the scrapers 23 and 24 due to the cutting is reduced, it is possible to prevent breakage and extend the life of the grooves.

  The first scraper 23 can advance and retract with respect to the circumferential surface of the first introduction roller 13, and the second scraper 24 can advance and retract with respect to the circumferential surface of the second introduction roller 14. As a result, the gap between the first scraper 23 and the peripheral surface of the first introduction roller 13 and the second scraper 24 and the second introduction roller 14 according to the thickness of the collected recovery bag and the like. It becomes possible to adjust the gap between the peripheral surface. Further, when the scrapers 23 and 24 are deformed due to long-term use, for example, the positions of the scrapers 23 and 24 with respect to the peripheral surfaces of the introduction rollers 13 and 14 are adjusted as appropriate, so that the first The cutting function of the recovery bag and the like by the cooperation of the scraper 23 and the groove 13a of the first introduction roller 13, and the cutting of the recovery bag and the like by the cooperation of the second scraper 24 and the groove 14a of the second introduction roller 14 The function can be maintained.

  The present invention is not limited to the above embodiment. In the above embodiment, the cutting blade is formed by forming the grooves 13a, 14a in the introduction rollers 13, 14, but, for example, the cutting blade is configured by forming a plurality of circular recesses in the introduction roller. Also good. Even if there is only one recess functioning as a cutting blade, it is possible to cut a collection bag or the like that has entered between the scraper and the peripheral surface of the introduction roller by cooperation with the scraper. On the contrary, it is possible to cut a collection bag or the like that has entered between the scraper and the peripheral surface of the introduction roller even if the small peripheral surface that functions as a cutting blade is formed and the peripheral surface of the introduction roller has a file shape. it can.
