Description

  The present invention relates to a waste supply apparatus for supplying waste to a waste treatment facility.

  Conventionally, as a means for supplying waste to a waste supply device such as an incinerator for processing waste, a hopper into which the waste is introduced, and a waste dropped from the hopper are transported to an incinerator, etc. The thing provided with the conveyor to perform is known.

  For example, Patent Document 1 includes a hopper and a conveyor including a conveyor belt, and after the waste dropped from the hopper is crushed by a crusher, the apparatus is conveyed to a downstream dust feeder by the conveyor belt. Is disclosed. In this apparatus, the conveyor belt extends upward from below the crusher, and waste is conveyed upward. Thus, in an apparatus in which waste is transported upward by the conveyor belt, when an excessive amount of waste falls on the conveyor belt, an excessive amount of waste falls downward due to its own weight, so that the waste is transported. The amount of waste generated is maintained at an appropriate level. However, when the conveyor belt is arranged so as to extend upward in this way, the entire device becomes large and when the waste falls and accumulates on the upstream side of the conveyor belt, it becomes a large lump. There is a risk of hindering the operation of the conveyor.

  On the other hand, as shown in FIG. 6, there is an apparatus configured such that the conveyor belt B22 extends in the horizontal direction. Such an apparatus is disclosed in Patent Document 2, for example. In the apparatus shown in FIG. 6, a conveyor B20 including a conveyor belt B22 is disposed below the hopper B10, and waste falls on the conveyor belt B22 from a discharge port B11b formed at the bottom of the hopper B10. And conveyor belt B22 conveys the waste which fell from this discharge port B11b in a horizontal direction.

JP 2009-227416 A Japanese Patent Laid-Open No. 10-061924

  In the conventional apparatus shown in FIG. 6, in the region A1 above the conveyor belt near the downstream end in the conveyor belt conveyance direction of the discharge port B11b of the hopper B10, it falls from the vicinity of the downstream end of the discharge port B11b and falls downstream in the conveyor belt conveyance direction. As a result of joining the waste proceeding to the side and the waste falling on the conveyor belt B22 upstream of the downstream end of the discharge port B11b and transported downstream by the conveyor belt B22, the vicinity of the downstream end In A1, the waste is clogged and consolidated, which makes it difficult to transport the waste and increases the load on the conveyor belt B22.

  In view of such circumstances, the present invention provides a waste transport apparatus capable of appropriately transporting waste while transporting waste in a horizontal direction by a conveyor belt and suppressing the load on the conveyor belt to a small level. For the purpose of provision.

  In order to solve the above-mentioned problems, the present invention is a waste supply device that supplies waste to a waste treatment facility for processing waste, and the waste is input from above to store the waste. In addition, a hopper main body having a discharge port for dropping the stored waste is formed in the bottom, and is provided below the hopper main body so as to communicate with the discharge port of the hopper main body and falls from the discharge port. A hopper provided with a discharge part through which waste passes inside, and a conveyor belt that is provided in communication with the discharge part and conveys waste dropped from the discharge part to the waste treatment facility A conveyor, and the conveyor belt is provided directly below the discharge unit and extends in a horizontal direction so as to convey the waste in the horizontal direction. The discharge unit is connected to the discharge port. From the position below the upstream end of the conveyor belt conveyance direction, it extends from the position below the downstream end of the conveyor belt conveyance direction of the discharge port to a position downstream of the conveyor belt conveyance direction, the hopper, A limiting member that is provided in the vicinity of a portion of the discharge port that is below the downstream end of the discharge direction of the conveyor belt, and restricts movement of waste in the discharge unit to the downstream side of the conveyor belt transfer direction, The conveyor belt is provided at the upstream end of the discharge unit in the conveying direction of the conveyor belt, and at the upstream end, waste is directed toward the downstream side of the conveying direction of the conveyor belt at a position closer to the conveyor belt than the lower end of the restricting member. A guide member that drops down, and the guide member extends in a direction substantially orthogonal to the conveyor belt conveyance direction. Further, it is a plate-like member that is inclined downward as it goes downstream in the conveying direction of the conveyor belt, and the lower end of the guide member is disposed closer to the conveyor belt than the lower end of the restricting member. A waste supply device is provided.

  According to this apparatus, since the conveyor belt extends in the horizontal direction, the apparatus can be reduced in size, and the restriction member and the guide member suppress the compaction of the waste in the vicinity below the downstream end of the discharge port. Therefore, appropriate conveyance of waste and reduction of load on the conveyor belt are realized.

  Specifically, the restricting member is disposed in the vicinity of a portion of the discharge portion located below the discharge port of the hopper body and below the downstream end of the discharge port in the conveyor belt conveyance direction, and downstream of the waste belt in the conveyor belt conveyance direction. The amount of waste that falls from the vicinity of the downstream end of the discharge port to the conveyor belt side and proceeds to the downstream side in the conveyor belt conveyance direction is reduced. Then, the guide member drops waste at the upstream end in the conveyor belt conveyance direction of the discharge unit toward the downstream side in the conveyance direction of the conveyor belt at a position closer to the conveyor belt than the lower end of the restriction member, and from the discharge port. Of the falling waste, the waste on the upstream side in the conveying direction of the conveyor belt is carried below the waste on the downstream side. Therefore, in the region between the discharge port and the conveyor belt, the flow of waste is rectified so as to face the downstream side in the conveyer belt conveyance direction, and the waste sequentially flows from the upper side toward the downstream side in the conveyer belt conveyance direction. Dropping and adding is suppressed. Therefore, the excessive waste is prevented from concentrating below the downstream end of the discharge port, and the waste is blocked from being clogged and consolidated at the downstream end of the discharge port.

  In the present invention, the restricting member extends horizontally and in a direction substantially orthogonal to the conveyor belt conveyance direction, and a lower portion thereof is located downstream of the upper portion in the conveyor belt conveyance direction. It is preferable to guide the waste having a shape and coming into contact with the restriction member in a direction inclined toward the downstream side in the conveyor belt conveyance direction as it goes downward (Claim 2).

  According to this configuration, the restricting member rectifies the flow of waste to the downstream side in the conveying direction of the conveyor belt also at the downstream end in the conveying direction of the conveyor belt at the discharge port of the hopper. Therefore, in the area between the discharge port and the conveyor belt, the flow of the entire waste is rectified so as to face the downstream side in the conveying direction of the conveyor belt. This more reliably suppresses clogging of waste near the lower end of the downstream end of the discharge port.

  Here, it is preferable that the inclination angle of the guide member with respect to the horizontal plane is set to be equal to or less than the inclination angle with respect to the horizontal plane in the direction in which the restriction member guides the waste.

  According to this configuration, the restricting member rectifies the flow of waste to the downstream side in the conveying direction of the conveyor belt, and the guide member is further downstream in the conveying direction of the conveyor belt than the waste falling from the vicinity of the restricting member. The waste is dropped on the conveyor belt toward the bottom, and the waste on the upstream side is carried below the waste on the downstream side that has fallen from above. Therefore, the flow of the entire waste is rectified so as to face the downstream side in the conveying direction of the conveyor belt, and the clogging of the waste near the downstream end of the discharge port is more reliably suppressed.

  In the present invention, the limiting member includes a plurality of bar-like members that extend horizontally and in a direction substantially orthogonal to the conveying direction of the conveyor belt, and are arranged in the vertical direction. Preferably, the lower bar-shaped members are disposed so as to be located downstream of the upper bar-shaped member in the conveying direction of the conveyor belt so that waste can enter between them. 4).

  According to this configuration, each bar-shaped member rectifies the entire waste flow toward the downstream side in the conveying direction of the conveyor belt, and allows the waste to enter between them, so that the vicinity of these bar-shaped members, that is, the hopper An excessive amount of waste is prevented from falling on the conveyor belt near the lower end of the discharge port at the downstream end in the conveying direction of the conveyor belt. This suppresses the concentration of waste near the downstream end of the hopper discharge port and suppresses clogging of waste near the downstream end of the discharge port.

  As described above, according to the present invention, it is possible to achieve proper conveyance of waste and suppression of load on the conveyor belt while downsizing the apparatus.

  A preferred embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a schematic sectional view showing a waste supply apparatus 1 according to an embodiment of the present invention.

  This waste supply apparatus 1 is connected to a waste processing facility (not shown) for processing waste such as an incinerator, and transports the waste to the waste processing facility. The waste supply apparatus 1 includes a hopper 10 and a conveyor 20.

  The hopper 10 stores the waste thrown in from above and drops the stored waste downward. The conveyor 20 conveys the waste dropped from the hopper 10 to the waste treatment facility side.

  The conveyor 20 includes a conveyor case 21 and a conveyor belt 22 accommodated in the conveyor case 21. The conveyor belt 22 extends in the horizontal direction, and conveys the waste placed on the upper surface thereof in the horizontal direction. An opening 21 a is formed in a portion of the upper surface of the conveyor case 21 located above the conveyor belt 22. The conveyor 20 is disposed immediately below the hopper 10. The opening 21a of the conveyor 20 communicates with the hopper 10, and the waste in the hopper 10 falls on the conveyor belt 22 through the opening 21a. An opening 21b that opens downward is formed in the bottom surface of the conveyor case 21 near the downstream end in the conveying direction of the conveyor belt 22. The waste treatment facility communicates with the opening 21b, and the waste conveyed by the conveyor belt 22 is discharged to the waste treatment facility through the opening 21b.

  The hopper 10 includes a hopper body 11, a discharge portion 13 positioned below the hopper body 11, a plurality of restriction rods (restriction members) 16, and a guide plate (guide member) 18. In the present embodiment, the hopper 10 has two restriction rods 16a and 16b.

  Waste is put into the hopper body 11 from above. The hopper body 11 stores the thrown-in waste inside. At the upper end of the hopper body 11, a charging port 11a is opened. Waste is introduced into the hopper main body 11 from above through the inlet 11a. A discharge port 11 b is opened at the bottom of the hopper body 11. The waste thrown in / stored in the hopper body 11 falls to the conveyor belt 22 side through the discharge port 11b.

  In this embodiment, as shown in FIGS. 1 and 2, the hopper body 11 has a cylindrical shape extending in the vertical direction, and has a substantially truncated pyramid shape that decreases as the inner flow area decreases downward. Specifically, the hopper body 11 is opposed to each other and extends downward between the downstream wall 12a and the upstream wall 12b that are inclined inward of the hopper body 11, and the downstream wall 12a and the upstream wall 12b. Side walls 12c and 12d that incline toward the inner side of the hopper main body 11 as it goes toward. The downstream wall 12a is located on the downstream side in the conveying direction of the conveyor belt 22 (hereinafter sometimes simply referred to as the conveying direction), and the upstream wall 12b is located on the upstream side in the conveying direction. And the part enclosed by the upper end of each wall 12a, 12b, 12c, 12d comprises the inlet 11a, the lower end part of each wall 12a, 12b, 12c, 12d comprises the bottom part of the hopper main body 11, and each wall The portion surrounded by the lower ends of 12a, 12b, 12c, and 12d constitutes the discharge port 11b.

  The discharge unit 13 communicates with the discharge port 11 b of the hopper body 11. The discharge unit 13 communicates with the opening 21a of the conveyor 20. The waste in the hopper body 11 dropped from the discharge port 11b passes through the inside of the discharge part 13 and falls onto the conveyor belt 22 from the opening part 21a.

  As shown in FIG. 7, the discharge unit 13 extends from a position below the upstream end in the transport direction of the discharge port 11 b to a position downstream in the transport direction from a position below the downstream end in the transport direction of the discharge port 11 b. ing. Therefore, a space located below the discharge port 11b and a space extending from this space to the downstream side in the transport direction are formed inside the discharge portion 13.

  In the present embodiment, the discharge unit 13 has a box shape in which an opening that matches the discharge port 11b is formed on the top surface, and an opening that matches the opening 21a of the conveyor 20 is formed on the bottom surface. Specifically, the discharge unit 13 includes an upstream wall 13b positioned at the upstream end in the transport direction and extending in the vertical direction (vertical direction); a downstream wall 13a positioned at the downstream end in the transport direction and extending in the vertical direction; Side walls 13c and 13d extending between the wall 13b and the downstream wall 13a are provided. The downstream wall 13a of the discharge unit 13 is located on the downstream side in the transport direction from the downstream end of the discharge port 11b in the transport direction. Accordingly, the side walls 13c and 13d extend from the upstream end in the transport direction of the discharge port 11b to a position downstream in the transport direction from the downstream end in the transport direction of the discharge port 11b. The discharge unit 13 has an upper wall 13e that extends between the upper ends of the portions of the side walls 13c and 13d that are on the downstream side of the discharge port 11b in the transfer direction with respect to the transfer direction, and constitutes the upper surface of the discharge unit 13.

  The upstream wall 13 b of the discharge unit 13 is formed integrally with the upstream wall 12 b of the hopper body 11 and extends downward from the lower end of the upstream wall 12 b of the hopper body 11. Further, of the side walls 13c and 13d of the discharge unit 13, portions upstream of the downstream end in the transport direction of the discharge port 11b are continuous with the side walls 12c and 12d of the hopper main body 11, respectively, and from the lower ends of these side walls 12c and 12d. It extends downward.

  Each restriction rod 16a, 16b is disposed in the discharge portion 13. That is, these restriction rods 16a and 16b are provided below the discharge port 11b in the vertical direction. Moreover, these restriction | limiting bars 16a and 16b are provided in the part vicinity of the discharge part 13 located in the downward direction of the conveyance direction downstream end of the discharge port 11b.

  Each of the limiting rods 16a and 16b has a cylindrical surface having central axes x1 and x2 (see FIG. 4) extending horizontally and in a direction orthogonal to the transport direction. In the present embodiment, the restriction rods 16a and 16b are cylindrical members.

  The restriction rods 16a and 16b are arranged so that the central axes x1 and x2 are arranged along an inclined surface that is inclined to the downstream side in the transport direction as it goes downward. That is, one limiting rod 16b is positioned below the other limiting rod 16a and downstream in the transport direction. In the present embodiment, the angle α1 with respect to the horizontal plane of the inclined surface passing through each of the central axes x1 and x2 and the angle α1 with respect to the horizontal plane in the direction in which the limiting rods 16a and 16b are arranged, and thus the contact surfaces of these limiting rods 16a and 16b ( The angle α1 between the broken line L1) and the horizontal plane in FIG. 4 is set to 45 degrees. The restriction rods 16a and 16b are separated from each other, and waste can pass between the restriction rods 16a and 16b.

  The upper limit rod 16a is provided at a position where the upper end thereof is substantially in contact with the upper wall 13e of the discharge portion 13 in the vertical direction. The upper limit bar 16a is provided at a position where the upstream end in the transport direction is substantially the same as the downstream end in the transport direction of the discharge port 11b in the horizontal direction. The lower limit bar 16b is provided at a position where the lower end of the lower limit bar 16b is substantially the same height as the lower end of the discharge portion 13, specifically, the lower end of the upstream wall 13b of the discharge portion 13. As shown in FIG. 2, the restriction rods 16 a and 16 b extend substantially over the entire discharge unit 13 in a direction that is horizontal and orthogonal to the transport direction.

  The guide plate 18 is a plate-like member and is provided at the upstream end of the discharge unit 13 in the transport direction. In the present embodiment, the guide plate 18 is configured separately from the discharge unit 13 and is attached to the discharge unit 13. The guide plate 18 is attached to the upstream wall 13 b of the discharge unit 13.

  The guide plate 18 extends in a direction orthogonal to the transport direction and is inclined downward from the upstream wall 13b of the discharge unit 13 toward the downstream in the transport direction from a portion above the lower end thereof. In the present embodiment, the guide plate 18 extends from a lower portion of the upstream wall 13b than a central portion in the vertical direction (vertical direction) to a position lower than the lower end of the lower limit bar 16b. That is, the distance h1 (see FIG. 4) between the lower end of the guide plate 18 and the upper surface of the conveyor belt is smaller than the distance h2 (see FIG. 4) between the lower end of the limiting rod 16b and the upper surface of the conveyor belt. The guide plate 18 extends below the lower end of the hopper body 11 and into the conveyor case 21. For example, the distance h1 between the lower end of the guide plate 18 and the upper surface of the conveyor belt is set to 420 mm, and the distance h2 between the lower end of the limiting bar 16b and the upper surface of the conveyor belt is set to 500 mm.

  In addition, the guide plate 18 extends from the upstream wall 13b of the discharge unit 13 toward the downstream side in the transport direction to a position separated from the downstream wall 13a of the discharge unit 13 to the upstream side. In this embodiment, it extends to the vicinity of the center of the discharge port 11b in the transport direction.

  The inclination angle α2 (see FIG. 4) of the guide plate 18 is set to be equal to or smaller than the angle α1 between the contact surfaces (broken lines in FIG. 4) L1 of the limiting rods 16a and 16b and the horizontal plane. In this embodiment, the inclination angle α2 of the guide plate 18 is set to 30 degrees, which is smaller than 45 degrees of the inclination angle α1 of the contact surface L1. The inclination angle α2 of the guide plate 18 is set smaller than the inclination angle α3 (see FIG. 1) of the upstream wall 12b of the hopper body 11. Specifically, the inclination angle α3 of the upstream wall 12b with respect to the horizontal plane is set to 45 degrees. Therefore, the inclination angle α2 = 30 degrees of the guide plate 18 is smaller than the inclination angle α3 = 45 degrees of the upper portion of the upstream wall 12b.

  The guide plate 18 is disposed above the conveyor belt 22 as shown in FIG. In this embodiment, in the direction which is horizontal and orthogonal to the conveyance direction, it extends over substantially the entire width direction of the conveyor belt 22 located below.

  Next, the flow of waste in the waste supply apparatus 1 configured as described above will be described.

  When waste is input from the input port 11 a of the hopper body 11, the waste falls to the lower portion of the hopper body 11 as shown in FIG. 3. The waste located in the lower part of the hopper main body 11 advances into the discharge part 13 through the discharge port 11b. Further, the waste passes through the discharge unit 13 and falls on the conveyor belt 22 through the opening 21 a of the conveyor case 21.

  When the conveyor belt 22 is driven, a force directed toward the downstream side in the transport direction acts on the waste on the conveyor belt 22. At this time, near the lower end of the discharge port 11b at the downstream side in the conveyance direction, the waste tends to proceed toward the downstream side in the conveyance direction under the conveyance force of the conveyor belt 22, but collides with the restriction rods 16a and 16b. This limits the progression. Then, near the lower end of the downstream end, the waste moves along the restriction rods 16a and 16b. That is, at this downstream end, as shown by the arrow Y1 in FIG. 3, the waste is conveyed in the direction of the arrangement of the restriction rods 16a and 16b, that is, along the contact surface L1 of the restriction rods 16a and 16b. Go downstream.

  Further, in the vicinity below the downstream end in the transport direction of the discharge port 11b, a part of the waste that collides with the restriction rods 16a and 16b passes between the restriction rods 16a and 16b and passes through the restriction rods 16a and 16b. Leaks into the space downstream in the transport direction from 16b. Specifically, when the downstream pressure exceeds a predetermined level, the waste material leaks into the space through the restriction rods 16a and 16b.

  In this way, the amount of waste that moves to the downstream side in the transport direction is kept small near the lower end of the discharge port 11b in the transport direction. Therefore, an excessive increase in pressure near the downstream end of the discharge port 11b is suppressed, that is, waste is prevented from being consolidated.

  Further, the waste moves along the guide plate 18 at the upstream end of the discharge unit 13 in the transport direction. That is, at this upstream end, the waste does not proceed along the vertical direction, but proceeds downstream in the transport direction as it goes downward. Here, as described above, the guide plate 18 extends below the lower end of the lower control rod 16b. Therefore, the upstream waste that has moved along the guide plate 18 advances downstream in the transport direction so as to slip into the control rod 16b side, that is, below the waste on the downstream side, as indicated by an arrow Y2 in FIG. . In particular, in this embodiment, the inclination angle of the guide plate 18 is set to be gentler than the inclination angle of the contact surface L1 of the restriction rods 16a and 16b. Therefore, the upstream waste movement direction is a direction toward the downstream side in the conveying direction of the conveyor belt 22 as compared with the downstream waste movement direction, and the upstream waste is more easily downstream waste. You can crawl into the underside. Here, the waste is dragged by the flow of the waste near the restriction rod 16b and the waste near the guide plate 18, and the waste is also near the center in the transport direction of the discharge unit 13 as shown by an arrow Y3 in FIG. As it goes downward, it proceeds downstream in the transport direction.

  In this way, in the discharge unit 13, the waste on the upstream side moves so as to go below the waste on the downstream side, and the flow of the waste is rectified so as to face the downstream side in the conveying direction of the conveyor belt. . Therefore, in the vicinity A1 below the downstream end of the discharge port 11b in the conveyance direction (see FIGS. 3 and 4), waste is prevented from being excessively concentrated and consolidated, and proper conveyance of the waste is realized. Moreover, the load concerning the conveyor belt 22 is restrained small.

  Here, the guide plate 18 and the hopper body 11 may be integrally formed. For example, as shown in FIG. 5, the upstream wall 12 b of the hopper body 11 extends below the lower end of the restriction rod 16 b, and the lower end portion of the upstream wall 12 b may function as the guide plate 18.

  Further, the number of the limiting rods 16a is not limited to the above. For example, as shown in FIG. 5, the upper limit bar 16a and the lower limit bar 16b are arranged so that the central axes x1 and x2 are arranged along an inclined surface that is inclined to the downstream side in the transport direction as it goes downward. In addition to the above, a limiting rod 16c may be provided below the upper limiting rod 16a in parallel with the lower limiting rod 16b.

  The limiting rods 16a and 16b are not limited to cylindrical members, and may be prismatic members such as triangular prisms and quadrangular prisms. Further, as the limiting rods 16a and 16b, C-shaped steel, H-shaped steel, or L-shaped steel may be used.

  Further, a plate-like member may be used in place of the limiting rods 16a and 16b. In this case, if the plate-like member is arranged in a posture that is inclined to the downstream side in the transport direction as it goes downward, the waste is further moved downstream in the transport direction while restricting the movement of the waste to the downstream side in the transport direction. Can be directed.

  The inclination angle of the guide plate 18 is not limited to the above. However, experiments have shown that if the inclination angle of the guide plate 18 is smaller than 30 degrees, the downward movement of the waste is excessively restricted, and the waste conveyance efficiency is deteriorated. Further, if the inclination angle of the guide plate 18 is larger than 45 degrees, it becomes difficult to move the waste sufficiently toward the downstream side in the transport direction, and the compaction in the vicinity of the downstream end of the discharge port 11b in the transport direction is sufficiently suppressed. I know I can't. Therefore, the inclination angle of the guide plate 18 with respect to the horizontal direction is preferably 30 degrees or more and less than 45 degrees.
