[Figure 4] Front cross-sectional view showing a chute according to one embodiment of the present disclosure. [Figure 5] A side view showing a chute with a knocker attached. [Modes for carrying out the invention]

[0016] In the following explanation, the directions indicated by arrows U, D, F, B, L, and R in the diagram will be defined as upward, downward, forward, backward, left, and right, respectively.

[0017] The chute 1 according to this embodiment guides a powdery substance to slide by its own weight from a predetermined upper position to a predetermined position. The powdery substance is, for example, incineration ash (ash generated by incinerating waste) or incineration fly ash (ash contained in the exhaust gas generated by incinerating waste). The chute 1 is configured to convey the powdery substance from the front upper side to the rear lower side by a guiding member 20 described later. Hereinafter, the conveyance direction of the powdery substance by the guiding member 20 is referred to as the conveyance direction E. The chute 1 includes a housing portion 10, a guiding member 20, an introduction portion 30, a discharge portion 40, a knocker 50, and a control device 60.

[0018] The housing portion 10 houses the guiding member 20 described later. Further, the housing portion 10 supports the guiding member 20. The housing portion 10 is formed in a long rectangular tube shape having an upper surface 10U, a lower surface 10D, a left side surface 10L, and a right side surface 10R. The housing portion 10 is provided along the conveyance direction E. The housing portion 10 includes an upper surface opening 11, an upper lid member 12, a side surface opening 13, a side surface knocker attachment member 14, a bottom surface opening 15, a bottom surface knocker attachment member 16, and a closing member 17.

[0019] The upper surface opening 11 shown in Fig. 2(a) is an opening formed in the upper surface 10U of the housing portion 10. The upper surface opening 11 is formed in a rectangular shape when viewed in the direction of arrow A. A plurality of upper surface openings 11 are formed at intervals in the conveyance direction E. In this embodiment, three upper surface openings 11 are formed.

[0020] The upper cover members 12 shown in Figures 1, 2, and 5 are members that close the upper opening 11. The upper cover member 12 is formed in the shape of a rectangular plate that is larger than the upper opening 11 in the view of arrow A. The upper cover member 12 is installed so as to close the upper opening 11 with its plate surface in contact with the upper surface 10U. The upper cover members 12 are installed for the upper opening 11 that is furthest downstream (lowest position) in the conveying direction E and for the upper opening 11 in the middle of the conveying direction E, respectively. The upper cover members 12 are formed to be movable (slidable) so as to expose the upper opening 11. This makes it possible to visually check (inspect) the conveying status of the powdery material by the guide member 20, which will be described later, through the upper opening 11.

[0021] The side openings 13 shown in Figures 1 and 4 are openings formed on the left side 10L and right side 10R of the storage section 10. The side openings 13 are formed in a rectangular shape when viewed from the side. Multiple side openings 13 are formed at intervals in the transport direction E.

[0022] The side knocker mounting members 14 shown in Figures 1, 2, 4, and 5 are members for attaching the knocker 50, which will be described later, to the left side 10L and right side 10R of the housing 10. The side knocker mounting members 14 are formed in a rectangular plate shape that is larger than the side opening 13 when viewed from the side. The side knocker mounting members 14 are provided so as to close the side opening 13 by having their plate surfaces abut against the left side 10L and right side 10R, respectively.

[0023] A knocker hole 14a is formed in the side knocker mounting member 14. The operating part 52 of the knocker 50, which will be described later, is inserted through the knocker hole 14a.

[0024] The bottom openings 15 shown in Figures 2(b) and 4 are openings formed on the lower surface 10D of the storage section 10. The bottom openings 15 are formed in a rectangular shape in the view of arrow C. Multiple bottom openings 15 are formed at intervals in the transport direction E.

[0025] The bottom knocker mounting member 16 shown in Figures 1, 2(b), 4, and 5 is a member for attaching a knocker 50, which will be described later, to the lower surface 10D of the housing 10. The bottom knocker mounting member 16 is formed in the shape of a rectangular plate that is larger than the bottom opening 15 when viewed from arrow C. The bottom knocker mounting member 16 is provided so as to close the bottom opening 15 by having its plate surface abut against the lower surface 10D.

[0026] A knocker hole 16a is formed in the bottom knocker mounting member 16. The working part 52 of the knocker 50, which will be described later, is inserted through the knocker hole 16a.

[0027] The closing member 17 shown in Figure 4 is a member that closes the knocker hole 16a. The closing member 17 is formed in the shape of a rectangular plate that is larger than the knocker hole 16a when viewed from the bottom. The closing member 17 is provided for each of the knocker holes 16a that do not have a knocker 50 installed. In this embodiment, the closing member 17 is provided for each knocker hole 16a. The closing member 17 is provided so as to close the knocker hole 16a with its plate surface in contact with the bottom knocker mounting member 16.

[0028] The guide member 20 shown in Figures 1, 3, 4, and 5 is for guiding powdery material. The guide member 20 comprises a main body 21, a mounting part 22, and a protective plate 23.

[0029] The main body portion 21 shown in Figures 3 and 4 forms the main structure of the guide member 20. The main body portion 21 is made of a flexible material, such as rubber. The main body portion 21 is formed by bending a longitudinal plate-shaped member. The main body portion 21 is arranged to be inclined downwards towards the rear along the conveying direction E.

[0030] As shown in Figure 4, the main body 21 is housed in the housing 10. The main body 21 is supported in the housing 10 such that its central portion in the width direction (left-right direction) is recessed downward relative to both ends (left and right ends) in the width direction. Specifically, the guide member 20 is supported in the housing 10 in a state of being bent in a U-shape when viewed from the front. Multiple through holes 21a are formed in both the left and right ends of the main body 21.

[0031] The mounting portion 22 shown in Figures 3 and 4 is a metal plate-shaped member. The mounting portion 22 is fixed to the back surface of the main body portion 21 by welding or the like. The mounting portion 22 is provided along both the left and right edges of the main body portion 21. The mounting portion 22 is provided with its plate surface facing left and right, between the left end of the main body portion 21 and the housing portion 10, and between the right end of the main body portion 21 and the housing portion 10. Through holes 22a are formed in the mounting portion 22. The through holes 22a are formed at positions corresponding to the through holes 21a of the main body portion 21.

[0032] The protective plate 23 shown in Figures 3 and 4 is a metal plate-shaped member. The protective plate 23 is formed in a circular shape. The protective plate 23 is fixed to the back surface of the main body 21 by welding or the like. Multiple protective plates 23 are provided between the left and right mounting parts 22. The protective plates 23 are positioned to correspond to the knocker holes 14a and 16a.

[0033] The guide member 20 formed in this manner is secured to the left and right sides of the housing 10 by inserting a bolt B through the through hole 21a of the main body 21 and the through hole 22a of the mounting part 22 from the inside of the housing 10, and by tightening a nut N on the tip of the bolt B from the outside of the housing 10 (see enlarged view of Figure 4). In this way, the guide member 20 is secured to the left and right sides of the housing 10. Here, the head of the bolt B is housed within the through hole 21a of the main body 21 so as not to protrude from the surface of the main body 21. This prevents the bolt B from obstructing the transport of powdery material.

[0034] Furthermore, the left and right central portions of the guide member 20 are positioned so as not to come into contact with the lower surface 10D of the storage section 10. In this way, the guide member 20 is fixed to the storage section 10 only at the left and right ends where the mounting portions 22 are provided, and the other parts are not fixed to the storage section 10 and are in a free state. Therefore, the guide member 20 has a structure that allows it to swing easily, and this swinging motion can facilitate the transport of powdery materials.

[0035] The introduction section 30 shown in Figure 5 is the part into which powdery material is introduced. The introduction section 30 is fixed to the upper surface 10U of the containment section 10 so as to communicate with the uppermost upper opening 11.

[0036] The discharge section 40 shown in Figure 5 is the part from which powdery material is discharged. The discharge section 40 is fixed to the storage section 10 so as to communicate with the lower opening of the storage section 10.

[0037] The knocker 50 shown in Figures 4 and 5 deforms the guide member 20. The knocker 50 deforms the guide member 20 by applying an impact to it. The knocker 50 is fixed to the housing section 10. Specifically, the knocker 50 is fixed to the side knocker mounting member 14 and can be attached to the left side 10L and right side 10R of the housing section 10 via the side knocker mounting member 14. In addition, the knocker 50 is fixed to the bottom knocker mounting member 16 and can be attached to the bottom surface 10D of the housing section 10 via the bottom knocker mounting member 16. Note that Figure 5 shows an example in which the knocker 50 is attached only to the left side 10L and right side 10R (and not to the bottom surface 10D).

[0038] Multiple knockers 50 are arranged along the transport direction E. Note that knockers 50 do not need to be provided for all side knocker mounting members 14 and bottom knocker mounting members 16; for example, they may be provided every other member. Each knocker 50 comprises a main body 51 and an operating part 52.

[0039] The main body 51 is the part that operates the operating part 52. The main body 51 is fixed to the side knocker mounting member 14 and the bottom knocker mounting member 16 on the outside of the housing part 10.

[0040] The working portion 52 is the part that acts on the guide member 20. When the knocker 50 is attached to the side knocker mounting member 14, the working portion 52 of the knocker 50 is inserted through the knocker hole 14a. When the knocker 50 is attached to the bottom knocker mounting member 16, the working portion 52 of the knocker 50 is inserted through the knocker hole 16a. The working portion 52 is provided so as to be in contact with the protective plate 23.

[0041] In the knocker 50 fixed to the housing 10 in this manner, the main body 51 is configured to have a piston inside and to be supplied with compressed air. The knocker 50 is configured such that when the piston is pushed down by the compressed air in the main body 51, the pushed-down piston strikes the working part 52. The impact received by the working part 52 is transmitted to the main body 21 via the protective plate 23 of the guide member 20. The impact force and operating interval of the working part 52 can be set by adjusting the flow rate of compressed air.

[0042] In this way, the knocker 50 can deform the guide member 20 (main body 21) by impacting it. Furthermore, since the guide member 20 is fixed to the housing section 10 only at both left and right ends, and not fixed in the middle, the knocker 50 can cause the guide member 20 to shake when it is impacted. By deforming and shaking the guide member 20 in this way, the discharge of powdery material on the guide member 20 to the discharge section 40 can be promoted.

[0043] The control device 60 shown in Figure 5 controls the operation of the knockers 50. The control device 60 is configured to supply compressed air to the knockers 50. Each of the knockers 50 (knockers 50A, 50B, and 50C) located on the same side of the housing section 10 is connected by a hose capable of supplying compressed air. The control device 60 operates the knockers 50 in order, starting with those located at the lowest position in the transport direction E.

[0044] Specifically, the control device 60 supplies compressed air to the lowest knocker 50A to activate it. The excess compressed air after supplying it to knocker 50A is supplied to the next lowest knocker 50B, activating knocker 50B. The excess compressed air after supplying it to knocker 50B is supplied to the lowest knocker 50C, activating knocker 50C. In this way, by operating the knockers 50 in order from the lowest position, if powdery material has accumulated at the lower part of the guide member 20, this powdery material can be transported to the discharge section 40, thereby preventing the powdery material from clogging the lower part of the guide member 20. Furthermore, by removing the accumulated powdery material from the lower part of the guide member 20 in order, it is possible to prevent the powdery material removed at the top from clogging the bottom, and the powdery material can be efficiently guided to the discharge section 40.

[0045] In the chute 1 configured as described above, the guide member 20 is made of a flexible material and is fixed to the storage section 10 only at both left and right ends, with the middle left and right sections being unfixed and free. Therefore, it is easily deformed and easily shaken. This facilitates the transport of powdery material to the discharge section 40, and consequently suppresses the accumulation of powdery material on the guide member 20. Furthermore, the knocker 50 can be used to impact the guide member 20, making it easy to deform or shake the guide member 20. This further facilitates the transport of powdery material to the discharge section 40.

[0046] Furthermore, since the guide member 20 has a shape in which the center in the width direction is recessed downward relative to both ends in the width direction, powdery material is less likely to scatter from the sides of the guide member 20, and the powdery material is easily guided to the discharge section 40. In addition, since the guide member 20 is housed inside the storage section 10 and is in a generally sealed state, the scattering of powdery material can be further suppressed.

[0047] Furthermore, since the guide member 20 is formed in a U-shape with an open top, the inside of the guide member 20 can be easily seen from the top opening 11. Therefore, it is possible to easily check the conveying status of powdery materials. In addition, maintainability can be improved.

[0048] Furthermore, by having the knocker 50 strike the protective plate 23 provided on the guide member 20, it is possible to prevent holes from being made in or damage to the main body 21.

[0049] As described above, the chute 1 according to this embodiment is A guide member 20 is flexible, positioned in an inclined position along the conveying direction E of the powdery material, and capable of guiding the powdery material. The housing portion 10 (support portion) supports both ends of the guide member 20 in the width direction relative to the transport direction E, It is equipped with the following features.

[0050] By configuring it in this way, it becomes difficult for powdery materials to accumulate.

[0051] Furthermore, the housing section 10 (support section) is, The guide member 20 is supported such that its central portion in the width direction is recessed downward relative to both ends of the guide member 20 in the width direction.

[0052] This configuration makes it easier to transport powdered materials.

[0053] Furthermore, the chute 1 according to this embodiment is The device further comprises a housing section 10 for housing the guide member 20.

[0054] By configuring it in this way, the scattering of powdery material can be suppressed.

[0055] Furthermore, the housing section 10 is The guide member 20 has a lower surface 10D (bottom surface) that covers it from below, and the lower surface 10D is positioned so as not to come into contact with the guide member 20.

[0056] By configuring it in this way, the guide member 20 can be made to move more easily, which in turn can facilitate the transport of powdery material.

[0057] Furthermore, the chute 1 according to this embodiment is The device further comprises a knocker 50 (deformable part) that is fixed to the housing section 10 and capable of deforming the guide member 20.

[0058] By configuring it in this way, the guide member 20 can be deformed to facilitate the transport of powdery material.

[0059] Furthermore, the deformed portion is It is composed of a knocker 50 that delivers an impact to the guide member 20.

[0060] By configuring it in this way, the guide member 20 can be easily deformed.

[0061] The aforementioned knocker 50 is Multiple knockers are arranged along the transport direction E, and they are operated sequentially, starting with the knocker 50 located at a lower position in the transport direction E.

[0062] By configuring it in this way, powdery materials can be made less likely to accumulate.

[0063] Although embodiments of the present invention have been described above, the present invention is not limited to the above configuration, and various modifications are possible within the scope of the invention as described in the claims.

[0064] For example, in this embodiment, the housing portion 10 is formed in the shape of a rectangular tube, but the shape of the housing portion 10 is not limited to this, and may be cylindrical, for example.

[0065] Furthermore, in this embodiment, the guide member 20 is deformed by a mechanical impact from the knocker 50, but the method of deforming the guide member 20 is not limited to this, and the guide member 20 may be deformed by any method such as vibration or pressure.

[0066] Furthermore, in this embodiment, the guide member 20 is formed such that the central part in the width direction is recessed (bends) downward relative to both ends in the width direction, but the shape of the housing part 10 is not limited to this and can be any shape. Furthermore, in this embodiment, the guide member 20 is formed in a U-shape with the central part in the width direction recessed downward relative to both ends in the width direction, but it is not limited to a U-shape and can be any shape that is recessed downward.

[0067] Furthermore, in this embodiment, the knocker 50 is provided on the left side 10L and the right side 10R of the housing section 10, but it is sufficient for it to be provided on any of the bottom surface 10D, the left side 10L, and the right side 10R, or it may be provided on all surfaces.

[0068] Furthermore, in this embodiment, the chute 1 is used to transport (guide) powdered materials such as incinerator ash and incinerator fly ash, but the chute 1 can be used to transport (guide) any powdered material.

[0069] Furthermore, in this embodiment, a control device 60 is provided as an example that operates the knockers 50 in order from the lowest position by supplying compressed air to them in order from the lowest position. However, the method of controlling the knockers 50 is not limited to this. For example, instead of supplying compressed air to multiple knockers 50 sequentially, the operating timing of the knockers 50 may be controlled by supplying compressed air to each knocker 50 individually at an appropriate timing.
