Description

  The present invention relates to a dust compacted storage and discharge device.

  Garbage generated at home is packed in bags and transported to a garbage disposal facility by a garbage truck. In order to temporarily store bagged garbage until a garbage truck arrives, a garbage compact storage and discharge device may be used.

  FIG. 1 is a schematic view showing an example of a dust compacted storage and discharge device. The waste compact storage / discharge device illustrated in FIG. 1 includes a cylindrical body 1. The trunk | drum 1 is installed horizontally. One end of the body 1 is connected to the inlet 3 and the other end is connected to the outlet 4. One or two spiral blades (feed blades 5) are attached to the inside of the body portion 1 along the inner wall. Further, a rotating mechanism 2 that rotates the body 1 around the central axis is attached to the body 1.

  In the waste compaction storage / discharge device shown in FIG. 1, bagged garbage is fed from the loading port 3. Garbage is guided to the trunk 1. When the body 1 is rotated by the rotation mechanism 2, the waste is transferred to the discharge port 4 side by the feed blade 5. At the time of storage, the discharge port 4 is closed by a lid, and the dust is stored in the body 1 in a compacted state. When the garbage in the trunk 1 is moved to a garbage truck or the like, the cover of the discharge port 4 is opened. And by rotating the trunk | drum 1, waste is discharged | emitted from the discharge port 4 to a garbage collection vehicle.

  As a related technique, Patent Document 1 (Japanese Patent Laid-Open No. 2001-293459) is cited. Patent Document 1 describes that a rotating drum type garbage storage device has a plurality of spiral blades inside a circular drum.

JP 2001-293459 A

  In the waste compaction storage / discharge device illustrated in FIG. 1, the feed blade is formed by one or two members. Usually, the feed blade is joined to the inner wall of the body 1 by welding. The operation | work which attaches a helical member to the trunk | drum 1 by welding is not easy. Also, if only the damaged part is to be replaced, a new member must be welded to the damaged part after cutting and removing the damaged part. Thus, when a feed blade is formed by one member, it is disadvantageous in that the difficulty of replacement work is increased. In addition, it requires a lot of materials and is difficult to process, so it must be expensive, and because of its complicated structure, problems such as operation stoppage and damage due to clogging are likely to occur when something other than a predetermined one is introduced.

  On the other hand, the garbage storage device described in Patent Document 1 is a device for fermenting garbage using microorganisms. In Patent Document 1, there is no description on the point of facilitating the replacement operation of the feed blades in the dust compacted storage / discharge device for temporarily storing bagged garbage.

  An object of the present invention is to provide a dust compacted storage and discharge device that can easily replace a feed blade when damaged, and can be operated stably at low cost.

  A dust compacted storage and discharge device according to the present invention is attached to a cylindrical trunk (1) rotating around a central axis extending in the horizontal direction, and an inner wall of the trunk (1), and is put into the trunk (1). And a feed blade portion for transferring the processed object. The feed blade portion includes a plurality of blade elements (51) arranged along a spiral centered on the central axis.

  In this invention, the feed blade part is formed by a plurality of blade elements (51) arranged along a spiral. Therefore, when the feed blade portion is damaged, only the damaged blade element among the plurality of blade elements (51) needs to be replaced. It is not necessary to replace the entire feed blade part, and it is not necessary to cut out only the damaged part. Therefore, it is advantageous from the viewpoint of maintainability.

  That is, according to the present invention, there is provided a waste compacted storage and discharge device that can easily replace the feed blades at the time of damage, and can stably maintain the transfer efficiency of waste and can be manufactured at low cost. Is done.

It is the schematic which shows an example of a refuse compaction storage discharge apparatus. It is a perspective view which shows the inside of a trunk | drum. It is a top view which shows a blade | wing element. It is an expanded view of a trunk | drum. It is a perspective view which shows an exit chute board. It is a perspective view when a trunk | drum is seen from the discharge port side. It is a see-through | perspective perspective view which shows an exit chute | shoot board.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. The dust compaction storage / discharge device according to the present embodiment includes a trunk portion 1 and a rotating mechanism 2 that rotates the barrel portion 1, as in the device illustrated in FIG. 1. The trunk portion 1 is cylindrical, and is connected to the inlet 3 at one end and connected to the outlet 4 at the other end. Capacity of the trunk portion 1 is about ^{1 m} 3 30 m ^3. The rotating mechanism 2 rotates the body 1 at about 3 to 7 rpm.

  FIG. 2A is a perspective view showing the inside of the body 1. As shown in FIG. 2A, a plurality of blade elements 51 (feed blade portions), two outlet chute plates 6 (exit chute portions), and four inlet inclined plates 7 (inlet) are provided in the body portion 1. An inclined plate group).

  The several blade | wing element 51 is attached in order to transfer refuse from the inlet 3 side to the outlet 4 side. Each of the plurality of blade elements 51 is attached to the inner wall of the body 1 by welding. The plurality of blade elements 51 are arranged along two spirals (a, b). In other words, the plurality of blade elements 51 includes a plurality of blade elements 51a disposed along the spiral a and a plurality of blade elements 51b disposed along the spiral b.

  The four inlet inclined plates 7 are provided closer to the inlet 3 than the plurality of blade elements 51. That is, the four inlet inclined plates 7 are provided in the vicinity of the inlet of the trunk portion 1. Similarly to the plurality of blade elements 51, the inlet inclined plate 7 is also joined to the inner wall of the body 1 by welding. Garbage thrown in from the inlet 3 is quickly guided to the central part of the trunk 1 by the four inlet inclined plates 7.

  The two exit chute plates 6 (6a, 6b) are provided to guide the waste to the discharge port 4. The two exit chute plates 6 are provided closer to the discharge port 4 than the plurality of blade elements 51. That is, the two exit chute plates 6 are provided in the vicinity of the discharge port 4. The two exit chute plates 6 (6a, 6b) are provided corresponding to the spirals a and b, respectively. That is, the outlet chute plate 6a is provided corresponding to the spiral a, and the outlet chute plate 6b is provided corresponding to the spiral b.

  The operation of the dust compacted storage / discharge device having the above-described configuration will be described. Garbage to be temporarily stored is put into the trunk 1 from the loading port 3 in a bag-packed state. During storage, the discharge port 4 is closed by a lid. When the trunk portion 1 is rotated by the rotation mechanism 2, the thrown-in waste is sent to the central portion of the trunk portion 1 by the inlet inclined plate 7. Garbage sent to the central portion of the trunk portion 1 is transferred to the discharge port 4 side by a plurality of blade elements 51. Thus, the dust is stored in a compacted state without collecting in the vicinity of the entrance of the body 1. When the stored garbage is transferred to a garbage truck or the like, the body 1 is rotated with the discharge port 4 opened. Thereby, the garbage lifted by the blade element 51 is moved onto the outlet chute plate 6 on the discharge port 4 side. Garbage is discharged from the discharge port 4 to the garbage truck through the exit chute plate 6. The garbage is mainly packed in bags, but the bags may be broken and the contents may pop out or may be thrown in without being packed. In this way, even garbage that is not packaged is compacted and stored by the compaction storage and discharge device.

  Assume that any of the plurality of blade elements 51 is damaged in the dust compacted storage / discharge device. In this case, only the damaged blade element 51 may be removed from the body 1 and replaced with a new blade element 51. Since it is not necessary to replace the entire plurality of blade elements 51, the replacement work can be easily performed. Also, it can be manufactured inexpensively with little damage.

  Subsequently, the plurality of blade elements 51 will be described in detail.

  As shown in FIG. 2A, the plurality of blade elements 51a arranged along the spiral a are attached at four locations at equal intervals per one rotation of the spiral a. In other words, the plurality of blade elements 51a are attached at 90 ° intervals on the circumference of the trunk portion 1 centering on the central axis. The same applies to the plurality of blade elements 51b arranged along the spiral b.

  It is preferable to attach the blade elements 51 at four positions at equal intervals per one rotation of the spiral from the viewpoint of efficiently transferring garbage. When the body portion 1 rotates, dust is lifted by each blade element 51. Assume that a certain blade element 51 lifts garbage. When the blade element 51 is positioned at the same height as the central axis c of the body portion 1, dust falls. At this time, one blade element 51 on the discharge port 4 side is positioned directly below the central axis c. Therefore, the fallen garbage is immediately lifted by the adjacent blade element 51. Immediately after the dust falls, it is lifted by the blade element 51 on the discharge port 4 side, so that it is efficiently transferred to the discharge port 4 side.

  FIG. 2B is a plan view showing each blade element 51. Each blade element 51 has a flat plate shape. Each blade element 51 includes a joint side having a shape corresponding to the inner wall of the body 1. Each blade element 51 is integrated with the inner wall of the body portion 1 by welding at the joint side. Each blade element 51 rises from the inner wall of the body 1 toward the center of the body 1. When a single spiral member is used as the feed blade, a complicated process must be performed to form the spiral member. On the other hand, in this embodiment, since each blade | wing element 51 is flat form, it can be produced in a simple process.

  FIG. 2C is a development view of the body 1. In FIG. 2C, a plurality of blade elements 51 and four inlet inclined plates 7 are drawn, and the illustration of the outlet chute plate 6 is omitted.

  As shown in FIG. 2C, the direction in which the central axis c extends is defined as the first direction. The blade element 51a along the spiral a and the blade element 51b along the spiral b are attached to the same position in the first direction at positions separated by 180 °. That is, the phases of the spiral a and the spiral b are shifted by 180 °. As described above, by providing the plurality of blade elements 51 along the double spirals whose phases are shifted by 180 °, it becomes possible to efficiently transfer the garbage.

  Further, as shown in FIG. 2C, each blade element 51 is attached so that the angle formed with the central axis c is θa. Here, the angle θa is not less than 30 ° and less than 90 °, preferably not less than 40 ° and not more than 70 °. When the angle is less than 40 °, it is difficult to obtain a propulsive force when transferring the waste, and when it is greater than 70 °, the dust is hardly lifted by the blade element 51.

  Next, the four inlet inclined plates 7 will be described. As shown in FIG. 2C, the four inlet inclined plates 7 are provided at the same position in the first direction. The four inlet inclined plates 7 are attached at intervals of 90 ° on the inner wall circumference of the trunk portion 1 centering on the central axis c. Each inlet inclined plate 7 is flat like the plurality of blade elements 51, and rises from the inner wall of the body 1 toward the central axis.

  In the vicinity of the entrance of the trunk portion 1, the dust introduced from the entrance 3 is likely to accumulate. If only two inlet inclined plates 7 are provided corresponding to the double helix, dust tends to stay near the inlet of the body 1. On the other hand, according to the present embodiment, by providing four inlet inclined plates 7, it is possible to increase the dust transfer capability in the vicinity of the inlet. Thereby, it is possible to prevent dust from being collected in the vicinity of the entrance of the trunk portion 1. In the present embodiment, four entrance inclined plates 7 are provided. However, if three or more entrance inclined plates 7 are provided, it is possible to increase the ability of transferring dust in the vicinity of the entrance as compared to the case where only two entrance plates are provided.

  The angle θb formed between each inlet inclined plate 7 and the central axis is 30 ° or more and less than 90 °, and preferably 40 ° or more and 70 ° or less. When the angle is less than 40 °, it is difficult to obtain a propulsive force when transferring the waste, and when it is greater than 70 °, the dust is difficult to be lifted by the inlet inclined plate 7.

  Next, the two exit chute plates 6 will be described. FIG. 3 is a perspective view showing the outlet chute plate 6. As shown in FIG. 3, the outlet chute plate 6 has a weld side joined to the inner wall of the body portion 1 by welding. Further, the outlet chute plate 6 is bent on the opposite side of the weld side, and a guide plate 61 is formed. The guide plate 61 may be formed by a member different from the outlet chute plate 6.

  FIG. 4 is a perspective view of the body 1 when viewed from the outlet 4 side. In FIG. 4, two outlet chute plates 6 (6 a, 6 b) and two blade elements 51 (a, b) provided closest to the discharge port 4 among the plurality of blade elements 51 are drawn. ing. As shown in FIG. 4, the outlet chute plate 6a is disposed corresponding to the blade element 51a, and the outlet chute plate 6b is disposed corresponding to the blade element 51b.

  FIG. 5 is a perspective view showing the outlet chute plate 6. As shown in FIG. 5, when the trunk portion 1 rotates, dust is lifted by the blade element 51 provided closest to the discharge port 4. The lifted garbage is transferred onto the exit chute plate 6. When the garbage is transferred from the blade element 51 onto the outlet chute plate 6, the outlet chute plate 6 is inclined so that the discharge port 4 side is in the downward direction. For this reason, the garbage slides down on the exit chute plate 6 and is discharged from the discharge port 4 to the outside (garbage truck). At this time, the guide plate 61 prevents dust from falling from the outlet chute plate 6.

  As described above, since the two outlet chute plates 6 are attached, when the outlet chute plate 6 is damaged, only the damaged outlet chute plate 6 needs to be replaced. When only one outlet chute plate 6 is configured, the entire outlet chute plate 6 must be replaced when it is partially damaged. On the other hand, according to the present embodiment, only the damaged outlet chute plate 6 needs to be replaced, so that the replacement work at the time of damage is facilitated.

  As described above, according to the present embodiment, since the plurality of blade elements 51 along the spiral are attached, it is possible to replace only the damaged blade elements 51 at the time of damage, and improve maintainability. . Further, since each blade element 51 can be formed into a flat plate shape, each blade element 51 can be easily produced at low cost.

  Moreover, according to this embodiment, the several wing | blade element 51 is attached along the double helix, Therefore The transfer capability of garbage can be improved.

  Furthermore, according to the present embodiment, since three or more (four) inlet inclined plates 7 are provided, it is possible to prevent dust from staying near the inlet of the trunk portion 1.

  Furthermore, according to this embodiment, since two exit chute plates 6 are provided corresponding to the double helix, the replacement work of the exit chute plate 6 can be facilitated.

  In addition, although this embodiment demonstrated the case where the several blade | wing element 51 was attached along the double helix, the some blade | wing element 51 may be attached along the single helix. When attached along the double helix, the propulsive force at the time of waste transfer can be increased. On the other hand, if it is attached along a single helix, the number of blade elements to be attached can be reduced, and the cost can be reduced.
