  However, the conventional dust storage and discharge apparatus has the following problems.

  Although the compression efficiency of the dust is increased by conveying the dust upward by the screw, the compression is naturally limited only by the screw in the storage tank body, and improvement of the compression efficiency cannot be expected.

  Moreover, there is a possibility of causing a bridging phenomenon, and the dust cannot be discharged smoothly when the dust is discharged.

  The present invention has been made in view of the above problems, and its object is to increase the compression efficiency while avoiding the bridging phenomenon of stored dust, and to efficiently and smoothly remove dust when discharging the dust. An object of the present invention is to provide a dust storage and discharge device that can discharge.

  In order to achieve the above object, a dust storage and discharge device according to a first aspect of the present invention includes a storage tank body having a dust storage space in the vertical direction, a charging section provided at a lower portion of the storage tank body, A charging means provided with a compressing and transferring means for compressing and transferring the dust charged from the charging part to the bottom of the storage space; a discharge part provided at the upper part of the storage tank body and discharging dust from the storage space to the outside; Guide means provided in the storage space and guiding the dust compressed and transferred to the bottom of the storage space toward the upper discharge portion.

  The dust storage and discharge device of the invention according to claim 2 is characterized in that the compression transfer means is a compression screw.

  In the dust storage and discharge device according to a third aspect of the present invention, the guide means is a spiral blade provided in a spiral shape in the storage space in the upper and lower directions and configured to be rotatable around a central axis. It is a feature.

  According to the present invention, the dust compressed in advance by the compression transfer means is introduced into the storage tank main body, and the dust is compressed again by the action of the guide means in the storage tank main body, thereby increasing the dust compression efficiency. In addition, the dust can be efficiently stored, and the dust can be discharged smoothly.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[Embodiment 1]
FIG. 1 thru | or FIG. 3 has shown schematic structure of the dust storage and discharge apparatus which concerns on this invention.

  This dust storage and discharge device 1 is provided at the upper part of the storage tank main body 2, the storage tank main body 2 having a dust storage space 2a in the vertical direction, the charging means 3 provided at the lower part of the storage tank main body 2, A discharge portion 4 for discharging dust to the outside and a spiral blade 5 as a guide means provided in the storage space 2a are provided.

  The storage tank body 2 is a vertical cylindrical body, the inside of which is the storage space 2a, and the top is formed in a truncated cone shape.

  The charging means 3 includes a charging part 31 and a compression screw 35 as a compression transfer means for compressing and transferring the dust thrown in from the charging part 31 to the bottom of the storage space 2a which is the lower part of the storage tank body 2. Yes.

  The charging unit 31 is provided with a charging lid 33 that can be freely opened and closed at an external opening (loading port) of a chute 32 that communicates with a transfer path 36 to be described later. It is made to throw in.

  The compression screw 35 is disposed in the transfer path 36. The transfer path 36 is arranged orthogonal to the chute 32 and along the tangential direction on the lower outer peripheral surface of the storage tank main body 2, and the compression screw 35 is disposed at the base end portion 36 a as shown in FIG. 2. The tip portion 36b is formed in a curved shape and communicates with the bottom portion of the storage space 2a.

  The compression screw 35 is configured to be rotationally driven by a drive motor 37 provided above the transfer path 36 via a transmission mechanism 38 including a sprocket and a chain. Thus, the dust thrown into the transfer path 36 through the chute 32 from the inlet is transferred to the bottom of the storage space 2a while being compressed.

  In this way, the dust is guided to the bottom of the storage space 2a by the compression screw 35 disposed at the lower part of the storage tank body 2, and therefore the height of the input lid (input port) 33 communicated with the compression screw 35 through the chute 32 is as follows. The lower position corresponds to the compression screw 35.

  The discharge unit 4 includes a discharge port 41 provided in the upper part of the storage tank body 2, a discharge chute 42 connected to the discharge port 41, and a discharge lid 43 that opens and closes the discharge port 41.

  The discharge port 41 is formed facing the storage space 2 a at an upper position opposite to the input unit 3, and a base end portion of the discharge chute 42 is connected to the discharge port 41.

  The upper surface of the discharge chute 42 is open, and the discharge lid 43 is opened and closed through this opening to a position where the discharge port 41 is closed by the expansion / contraction operation of the expansion / contraction cylinder 44 and a position where the discharge port 41 is opened.

  The spiral blade 5 is formed in a so-called ribbon screw shape without a shaft portion and having only a screw portion, and is formed in a so-called ribbon screw shape with a hollow inside, and has an inclined surface that is inclined downward toward the outside in a spiral manner.

  The spiral blade 5 is integrally provided on a turntable 51 provided on the bottom surface in the storage tank main body 2. The center axis of the turntable 51 is connected to a drive motor 52 through a transmission mechanism 53 including a sprocket and a chain, and the drive motor 52 is rotatable in a horizontal state around the center axis. Accordingly, the rotation of the turntable 51 causes the spiral blade 5 to also rotate about the central axis, and the dust introduced to the bottom of the storage space 2a by this rotation slides on the inner wall of the storage tank body 2 along the inclined surface. It is conveyed upward while touching.

  Next, dust storage and discharge operations by the dust storage and discharge device configured as described above will be described.

  First, the charging lid 33 is opened and dust is introduced into the transfer path 36 where the compression screw 35 is disposed through the chute 32. The thrown dust is transferred to the storage tank main body 2 side while being compressed in the transfer path 36 by the rotation of the compression screw 35, and is introduced into the bottom of the storage space 2a.

  The dust introduced into the bottom of the storage space 2a while being compressed in this way is slid on the inner wall of the storage tank body 2 along the inclined surface by the rotational operation of the spiral blade 5 through the turntable 51 by the drive motor 52. It is conveyed upward while touching. Then, when the dust reaches the uppermost position of the spiral blade 5, it falls again downward through the inner cavity, and is gradually stored in the storage space 2a while repeating this circulation operation.

  Accordingly, when dust is stored in the storage tank body 2 to some extent, the dust is compressed between the inner wall at the top of the storage tank body 2 by being conveyed upward by the spiral blade 5. It is guided to the side and falls downward through the hollow portion inside the spiral blade 5.

  In this way, the dust compressed in advance by the compression screw 35 is introduced into the storage tank main body 2, and the dust is compressed again by the action of the spiral blade 5 in the storage tank main body 2, thereby increasing the compression efficiency of the dust. Can be stored efficiently. In addition, since the dust is compressed and stored in the storage tank body 2 while being circulated, it is possible to avoid the occurrence of a bridge phenomenon by the circulation action, and it is possible to smoothly discharge the dust described later.

  Furthermore, since the dust is introduced into the bottom of the storage space 2a by the compression screw 35, the dust throwing position of the throwing portion 31 can be made as low as possible. Can respond.

  Note that the compression screw 35 and the spiral blade 5 may be operated intermittently in conjunction with, for example, the opening / closing operation of the charging lid 33, or may be operated for a predetermined time by a switch operation. Depending on the situation, it may be operated continuously.

  And when discharging the dust stored in the storage tank main body 2 as described above, the discharge port 41 is opened by the discharge lid 43 while rotating the spiral blade 5, so that the spiral blade 5 moves upward. The conveyed dust is sequentially discharged from the discharge port 41 to the outside through the discharge chute 42 by the action of the inclined surface. At this time, in the storage tank main body 2, since the occurrence of the dust bridging phenomenon is avoided by the circulation action as described above, the dust can be smoothly discharged.

  In addition, by disposing the input port of the garbage collection vehicle at the carry-out end of the discharge chute 42, for example, as shown in FIG. 1, the garbage in the storage tank body 2 can be easily accommodated in the garbage collection vehicle, Can be transported. That is, the position of the discharge port 41, the length and shape of the discharge chute 42, and the like may be set so that the dust is easily accommodated according to the transport vehicle that transports the dust.

  In addition, when dust is fully stored in the storage space 2a of the storage tank main body 2, it is necessary to prohibit the addition of more dust. As this means, for example, the opening / closing frequency of the closing lid 33 is counted, and when the predetermined number of times is reached, the closing lid 33 is locked in a closed state to prohibit the opening. In other words, since the total amount of dust can be estimated from the amount of dust that can be thrown in by opening the charging lid 33 once, the amount of dust that will reach the full amount by comparing this with the storage volume of the storage tank body 2. What is necessary is just to set the frequency | count of opening and closing of the lid | cover 33. FIG. The full amount of dust may be detected based on the load acting on the drive motor 37 that drives the compression screw 35, or the full amount may be detected by other means.

[Embodiment 2]
4 to 6 show another configuration of the dust storing and discharging apparatus of the present invention.

  The dust storage and discharge device 1 uses a screw 6 as a spiral blade disposed in the storage space 2a.

The screw 6 includes a shaft portion 61 and a screw portion 62 provided on the outer periphery of the shaft portion 61, and the shaft portion 61 is arranged upright at the central portion of the storage space 2a. The screw part 62 has its tip approaching the inner wall of the storage tank body 2 and is arranged from the bottom part to the top part of the storage space 2a. The upper end of the shaft part 61 projects from the upper surface of the storage tank body 2 to the outside. The upper end of the screw 6 is connected to a drive motor 64 via a transmission mechanism 63 composed of a sprocket and a chain, and the drive motor 64 is configured to freely rotate the screw 6.

  On the other hand, a scraping blade 7 is provided in the upper part of the storage space 2a. The scraping blades 7 are for scraping and discharging the internal dust from the discharge port 41 of the discharge section 4 to the outside. As shown in FIG. 5, a plurality of rotatable sheets formed in a curved shape so as to be easily scraped. The blade member 71 is provided. Specifically, the base end portions of the plurality of blade members 71 are integrally connected to the hollow shaft portion 72, and the shaft portion 72 is connected to the upper end portion of the shaft portion 61 of the screw 6 having a small diameter. It is rotatably inserted through a bearing. The upper end of a shaft 72 projecting outward from the upper surface of the storage tank body 2 is connected to the drive motor 64 via a transmission mechanism 73 composed of a sprocket and a chain. It can be rotated freely.

  In this way, the scraping blade 7 and the screw 6 are driven to rotate by the same drive motor 64, but each of the transmission mechanism 63 and the transmission mechanism 73 so that the scraping blade 7 rotates faster than the rotation of the screw 6. The gear ratio is set.

  In addition, about other structures, such as the injection | throwing-in part 3 and the discharge part 4, it is the same as that of the dust storage and discharge apparatus of Embodiment 1 mentioned above, The same code | symbol is attached | subjected to the same member and description is abbreviate | omitted.

  Next, dust storage and discharge operations by the dust storage and discharge device configured as described above will be described.

  First, the charging lid 33 is opened and dust is introduced into the transfer path 36 where the compression screw 35 is disposed through the chute 32. The thrown dust is transferred to the storage tank main body 2 side while being compressed in the transfer path 36 by the rotation of the compression screw 35, and is introduced into the bottom of the storage space 2a. At this time, the screw 6 and the scraping blade 7 are stopped.

  The dust introduced into the bottom of the storage space 2 a while being compressed in this way is sequentially pushed onto the conveying surface of the screw 6 by the pushing action of the compression screw 35, whereby the dust is screwed into the storage tank body 2. 6 is transported upward along the transport surface 6 and compressed.

  Thus, by introducing the dust previously compressed by the compression screw 35 into the storage tank main body 2 and further compressing the dust in the storage tank main body 2, the compression efficiency of the dust can be increased, and the dust is made efficient. It can be stored well.

  The compression screw 35 may be operated intermittently in conjunction with, for example, the opening / closing operation of the closing lid 33, or may be operated for a predetermined time by a switch operation, and further if necessary. You may make it operate | move continuously.

  And when discharging the dust stored in the storage tank main body 2 as mentioned above, the discharge port 41 is opened by the discharge lid 43 and the screw 6 and the scraping blade 7 are driven to rotate. As a result, the dust in the storage tank body 2 is sequentially conveyed upward by the screw 6, and is discharged to the outside from the discharge port 41 by the scraping blade 7 that rotates faster than the screw 6 at the upper part thereof. It is discharged through.

  As described above, even if a bridge phenomenon occurs due to the compression of the dust in the storage tank body 2 by forcibly discharging the dust by the scraping blades 7 while being sequentially transported upward by the screw 6, It can be reliably released by the rotational drive of the screw 6 and the scraping blade 7, and thus the dust can be discharged smoothly.

  In addition, by disposing the input port of the garbage collection vehicle at the carry-out end of the discharge chute 42, for example, as shown in FIG. 4, the garbage collection vehicle can easily accommodate the dust in the storage tank body 2, and the processing site Can be transported. That is, the position of the discharge port 41, the length and shape of the discharge chute 42, and the like may be set so that the dust is easily accommodated according to the transport vehicle that transports the dust.

  Note that the above-described embodiment is merely a preferred embodiment of the present invention, and the present invention is not limited to this, and various design changes can be made within the scope thereof.

  For example, the guide means is not limited to the spiral blade 5 or the screw 6, but may be any means that guides the dust compressed and transferred to the bottom of the storage space 2a toward the upper discharge portion 4, for example, It may be a push plate provided so as to be movable up and down in the storage space 2a.
