[Technical Field]

[0001] The present disclosure relates to a conical dryer and a powder discharge promoting device. [Background technology]

[0002] Patent Document 1 discloses a conical dryer for drying powder. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2003-65674 Summary of the Invention [Problem to be solved by the invention]

[0004] The powder container of the conical dryer is provided with a powder outlet and an on-off valve for opening and closing the powder outlet. When discharging the powder from the powder container, the powder container is rotated so that the powder outlet faces downward, and the on-off valve is opened. As a result, the powder in the powder container falls downward and is discharged to the outside through the powder discharge port.

[0005] When discharging the powder from the powder container, bridges or ratholes may occur in the powder inside the powder container, preventing the powder from being discharged. Bridges and ratholes are difficult to break up by simply rotating the powder container. For this reason, it is conceivable to open a manhole provided in the powder container, insert a rod-shaped member through the manhole into the powder container, and destroy the bridge or rathole. However, when the manhole is opened, the powder in the powder container is exposed to the outside air, which may cause foreign matter to get mixed in. In addition, contact between the powder and the rod-shaped member may also cause foreign matter to get mixed in.

[0006] For these reasons, there has been a demand for a technology that can easily promote the discharge of powder from a powder container without directly accessing the powder in the container through a manhole or the like. [Means for solving the problem]

[0007] A conical dryer according to an embodiment of the present disclosure includes a powder container having an outlet through which powder to be dried is discharged, and a vibration mechanism provided at the outlet to apply vibrations to the outlet. [Effects of the Invention]

[0008] According to the present disclosure, it is possible to easily promote the discharge of powder from the powder container. [Brief explanation of the drawings]

[Figure 3] FIG. 3 is a perspective view of the vibration mechanism. [Figure 4] FIG. 4 is a plan view of the vibration mechanism.

DETAILED DESCRIPTION OF THE INVENTION

[0010] First, the contents of the embodiment will be listed and explained. [Outline of the embodiment]

[0011] (1) A conical dryer according to an embodiment of the present disclosure includes a powder container having an outlet through which powder to be dried is discharged, and a vibration mechanism provided at the outlet that applies vibrations to the outlet.

[0012] According to the above configuration, the vibrations applied to the discharge port from the vibration mechanism propagate to portions of the powder container other than the discharge port and further to the powder inside the powder container, thereby vibrating the powder inside the powder container and breaking down bridges and ratholes that may occur in the powder inside the powder container. As a result, it is possible to easily promote the discharge of powder from the powder container without directly accessing the powder in the container through a manhole or the like.

[0013] (2) In the conical dryer of (1) above, the vibration mechanism may include a vibration generating source driven by compressed air. In this case, the vibration mechanism does not need to be provided with a drive source such as a motor, and the vibration mechanism is relatively lightweight. As a result, the powder container can be rotated while the vibration mechanism is attached to the flange portion, and there is no need to remove the vibration mechanism from the powder container.

[0014] (3) In the conical dryer of (1) or (2) above, when the discharge outlet has a flange portion, the vibration mechanism may include a vibration generating source and a fixing member that fixes the vibration generating source to the flange portion. In this case, the vibration mechanism can apply vibration generated by the vibration source to the flange portion via the fixed member.

[0015] (4) In any one of the conical dryers (1) to (3) above, the fixing member may include a strip-shaped member that is wrapped around the outer peripheral surface of the flange portion, a first surface of the strip-shaped member may include a fixing surface to which the vibration generating source is fixed, and a second surface opposite to the first surface may include an abutment surface that abuts against the outer peripheral surface of the flange portion. In this case, the vibration of the vibration generating source is propagated around the entire outer periphery of the flange portion via the belt-shaped member. Also, by wrapping the belt-shaped member around the outer periphery of the flange portion, the vibration generating source can be fixed to the flange portion. Therefore, the vibrating mechanism can be easily fixed to the flange portion.

[0016] (5) In any one of the conical dryers (1) to (3) above, the fixing member may include a fixing plate fixed between the outer peripheral surface of the flange portion and the outer peripheral surface of the connecting flange portion connected to the flange portion, a first surface of the fixing plate may include a fixing surface to which the vibration generating source is fixed, and a second surface opposite to the first surface may include an abutment surface that abuts against the outer peripheral surface of the flange portion. In this case, vibrations from the vibration generating source are propagated to the outer peripheral surface of the flange portion via the fixing plate. Also, if protruding plate portions that protrude radially inward are provided on both ends of the fixing plate, the protruding plate portions can be clamped by the bolts and nuts that connect the flange portion and the connecting flange portion, and the fixing plate can be firmly fixed to the flange portion.

[0017] (6) Another embodiment is a powder discharge promoting device for a conical dryer, which includes a powder container having an outlet through which powder to be dried is discharged. The powder discharge promoting device includes a vibration mechanism that applies vibration to the outlet.

[0018] [Details of the embodiment] Preferred embodiments will now be described with reference to the drawings. At least some of the embodiments described below may be combined in any manner. [Regarding the first embodiment] FIG. 1 is a front view showing an example of a conical dryer according to a first embodiment. In FIG. 1, a conical dryer 1 includes a powder container 2 , a pair of support columns 4 and 6 , and a drive mechanism 8 . The conical dryer 1 is a device for drying powder. The powder container 2 contains the powder to be dried. A pair of supports 4 and 6 rotatably support the powder container 2. A drive mechanism 8 has the function of driving the powder container 2 to rotate.

[0019] The powder container 2 has a container body 10, a manhole portion 12, and a discharge port 14. The container body 10 has a shape that combines a cylindrical portion 10a, a first conical portion 10b, and a second conical portion 10c. The container body 10 has an internal storage space S that stores powder. The container body 10 further includes a heat medium jacket 11. The heat medium jacket 11 is provided to cover the outside of the storage space S. The heat medium jacket 11 includes a circulation path through which a heat medium such as hot water circulates. The powder in the storage space S is dried by the heat from the heat medium circulating through the heat medium jacket 11.

[0020] The manhole portion 12 is provided at the outer apex of the first conical portion 10b. The manhole portion 12 has a frame portion 12a and a lid portion 12b. An opening that opens to the storage space S is provided at the outer apex. The frame portion 12a is provided at the opening. The lid portion 12b is connected to the frame portion 12a via a hinge or the like. The lid portion 12b closes the opening in an openable manner.

[0021] The discharge port 14 is provided at the outer apex of the second conical portion 10c. The powder inside the container body 10 is discharged from the discharge port 14. An on-off valve 15 is provided at the discharge port 14. When the on-off valve 15 is closed, it prevents the powder inside the storage space S from being discharged from the discharge port 14. When the on-off valve 15 is opened, the powder inside the storage space S is discharged from the discharge port 14. In addition, a vibration mechanism 16 is provided at the outlet 14. The outlet 14 and the vibration mechanism 16 will be described in detail later. A transport pipe 17 is further connected to the discharge port 14. The transport pipe 17 is a pipe for transporting the powder discharged from the discharge port 14 to the next process. The transport pipe 17 is detachable from the discharge port 14.

[0022] The powder container 2 further has a first shaft portion 18 and a second shaft portion 20. The first shaft portion 18 and the second shaft portion 20 are provided on the cylindrical portion 10a of the container body 10. The first shaft portion 18 and the second shaft portion 20 are provided along the rotation axis C1. The rotation axis C1 is aligned with the radial direction of the cylindrical portion 10a.

[0023] At the upper ends of the pair of support columns 4 and 6, bearings 4a and 6a are provided. The first shaft portion 18 and the second shaft portion 20 are rotatably supported by bearings 4a, 6a of the support columns 4, 6. This allows the powder container 2 to rotate freely around the rotation axis C1.

[0024] The first shaft portion 18 has a hole therein along the axial direction. This hole communicates between the accommodation space S and a suction port 19. A vacuum pump (not shown) is connected to the suction port 19. The vacuum pump is capable of evacuating the accommodation space S. This adjusts the atmosphere within the accommodation space S. The second shaft portion 20 has a path therein through which the heat medium passes to be supplied to the heat medium jacket 11. The heat medium supplied from the supply / discharge port 21 passes through the path of the second shaft portion 20 and is supplied to the heat medium jacket 11 via the supply / discharge pipe 22.

[0025] The drive mechanism 8 includes a motor 8a and a reducer 8b. The motor 8a generates a rotational force. The reducer 8b reduces the rotational force of the motor 8a and transmits it to the second shaft portion 20. In this way, the drive mechanism 8 drives the powder container 2 to rotate. As the powder container 2 rotates, the powder in the powder container 2 is agitated.

[0026] The conical dryer 1 having the above-described configuration can dry the powder being stirred by the heat of the heat medium. When the dried powder is to be discharged from the discharge port 14, the powder container 2 is stopped so that the discharge port 14 faces downward, as shown in FIG. 1. Then, the on-off valve 15 is opened. This causes the powder in the storage space S to fall downward and be discharged into the conveying pipe 17.

[0027] Fig. 2 is a cross-sectional view of a main part of the powder container 2. Fig. 2 is an enlarged view of the discharge port 14 of the powder container 2. Fig. 2 is a cross-sectional view including a central axis C2 (described later). As described above, the outlet 14 is provided with the on-off valve 15 and the vibration mechanism 16. In addition, the outlet 14 is connected to a transfer pipe 17.

[0028] In Figure 2, the second conical portion 10c of the vessel body 10 has a wall portion 24. The inner surface of the wall portion 24 is glass-lined. That is, the wall portion 24 has a wall main body 26 and a glass-lining layer 28. The wall main body 26 is a plate-shaped member made of a steel plate or the like. The glass-lining layer 28 is a surface-treated layer made of glass or the like formed on the inner surface of the wall main body 26. A heat medium jacket 11 is provided on the outer surface of the wall main body 26.

[0029] The second conical portion 10c has an opening 10c1 at the top. The outlet 14 is provided so as to protrude outward from the periphery of the opening 10c1. The outlet 14 has a tubular portion 30 and a flange portion 32. The tubular portion 30 is a tubular member that is connected to the periphery of the opening 10c1. The flange portion 32 has a flange main body 32a and a ring member 32b. The flange body 32a is an annular member extending radially outward from the tip edge of the cylindrical portion 30. The flange body 32a is provided concentrically with the cylindrical portion 30. The cylindrical portion 30 and the flange body 32a are integrally formed on the wall portion 24 of the container body 10. Therefore, the cylindrical portion 30 and the flange body 32a are formed from a steel plate or the like. Furthermore, the glass lining layer 28 is provided on the inner peripheral surface of the cylindrical portion 30 and the outer surface of the flange body 32a.

[0030] The ring member 32b is a member disposed outside the tubular portion 30. An annular step portion 32b1 is provided on the inner peripheral side of the ring member 32b. The step portion 32b1 abuts against a first surface 32a1 of the flange main body 32a. The first surface 32a1 is the surface of the outer surface of the flange main body 32a that faces the container main body 10. The step portion 32b1 is provided to correspond to the outer diameter of the flange main body 32a. As a result, the center of the ring member 32b is disposed to coincide with the central axis C2. The central axis C2 is the central axis of the tubular portion 30 and the flange main body 32a.

[0031] The ring member 32b has a plurality of through holes 34. The plurality of through holes 34 are holes arranged along a circle centered on the central axis C2. The plurality of through holes 34 are parallel to the central axis C2. A plurality of bolts 36 are inserted into the plurality of through holes 34.

[0032] As described above, the conveying pipe 17 is connected to the discharge port 14. A connection flange portion 17a is provided at the tip of the conveying pipe 17. The connection flange portion 17a has a plurality of through holes 38. The plurality of through holes 38 are holes arranged along a circle centered on the central axis C2. The plurality of through holes 38 are parallel to the central axis C2. The plurality of through holes 38 are provided to correspond to the plurality of through holes 34. The plurality of bolts 36 are inserted into both the through-holes 34 and 38. Nuts 40 are threaded onto the ends of the bolts 36. The plurality of bolts 36 and the plurality of nuts 40 axially tighten the ring member 32b (flange main body 32a) and the connection flange portion 17a. As a result, the plurality of bolts 36 and the plurality of nuts 40 connect the discharge port 14 and the conveying pipe 17.

[0033] The on-off valve 15 is provided between the flange main body 32a and the connection flange portion 17a. An annular gasket 42 is provided between the on-off valve 15 and the flange main body 32a. In addition, an annular gasket 44 is provided between the on-off valve 15 and the connection flange portion 17a. The on-off valve 15 is sandwiched between the flange main body 32a and the connection flange portion 17a via the gaskets 42, 44.

[0034] The on-off valve 15 is a butterfly valve having an annular main body 15a and a disk 15b rotatably mounted on the inner circumferential opening of the main body 15a. The disk 15b rotates in response to rotation of a handle 15c (see FIG. 1) to open and close the inner circumferential opening of the main body 15a. In this way, the on-off valve 15 releasably closes the discharge port 14.

[0035] The vibration mechanism 16 is provided on the ring member 32b (flange portion 32) of the discharge port 14. The vibration mechanism 16 has an air vibrator 46 and a fixing member 48. The air vibrator 46 is cylindrical and is a vibration generating source that generates vibrations when driven by compressed air supplied from the outside. A piston that moves in the axial direction of the air vibrator 46 is provided inside the air vibrator 46. The piston is reciprocated by compressed air. The air vibrator 46 generates vibrations through this reciprocating motion. The generated vibrations vibrate the entire air vibrator 46. Therefore, the vibrations generated by the air vibrator 46 are transmitted to the member to which the air vibrator 46 is attached.

[0036] The fixing member 48 is a member for fixing the air vibrator 46 to the ring member 32b. The fixing member 48 includes a belt-shaped member 50. The belt-shaped member 50 is wound around the outer peripheral surface 32b2 of the ring member 32b. FIG. 3 is a perspective view of the vibration mechanism 16, and FIG. 4 is a plan view of the vibration mechanism 16. As shown in FIG. The strip-shaped member 50 is a member formed in an annular shape and has a first surface 50a facing radially outward and a second surface 50b facing radially inward. The air vibrator 46 is fixed to a first surface 50a (FIG. 3) of the belt-shaped member 50. Therefore, the first surface 50a includes a fixing surface 50a1 to which the air vibrator 46 is fixed.

[0037] Furthermore, when the belt-shaped member 50 is wound around the ring member 32b, the second surface 50b abuts against the outer peripheral surface 32b2 of the ring member 32b. Therefore, the second surface 50b includes an abutment surface that abuts against the outer peripheral surface 32b2.

[0038] The belt-shaped member 50 includes a first belt-shaped portion 52 to which the air vibrator 46 is fixed, a second belt-shaped portion 54, and a pair of connecting members 56. The first belt-shaped portion 52 and the second belt-shaped portion 54 are semicircular members formed using a metal band such as a steel plate or an aluminum alloy. The pair of connecting members 56 include bolts and nuts, etc., and connect both ends of the first belt-shaped portion 52 and both ends of the second belt-shaped portion 54. When the first band-shaped portion 52 and the second band-shaped portion 54 are combined and wound around the ring member 32b, a predetermined gap T (FIG. 4) is formed between both ends of the first band-shaped portion 52 and both ends of the second band-shaped portion 54. The bolts and nuts of the connecting member 56 are tightened in a direction that narrows the predetermined gap T. Thus, the band-shaped member 50 tightens the ring member 32b in the radial direction and is fixed to the ring member 32b.

[0039] In this way, the fixing member 48 (belt-shaped member 50) is interposed between the air vibrator 46 and the ring member 32b, and fixes the air vibrator 46 to the ring member 32b. The vibration mechanism 16 applies vibration from the air vibrator 46 to the discharge port 14 (flange portion 32) via the belt-shaped member 50.

[0040] The vibrations applied from the air vibrator 46 to the flange 32 of the discharge port 14 are transmitted to the container body 10 and then to the powder inside the container body 10. This vibrates the powder inside the container body 10, and bridges and ratholes that occur in the powder inside the container body 10 can be broken down. As a result, it is possible to easily promote the discharge of powder from the powder container 2 without directly accessing the powder in the container body 10 through the manhole portion 12 or the like. Furthermore, in this embodiment, vibration is applied to the flange portion 32, so that even if the container body 10 is covered by the heat medium jacket 11, vibration can be applied to the powder inside the container body 10, thereby breaking down bridges and ratholes. In this way, the vibration mechanism 16 of this embodiment functions as a powder discharge promoting device that promotes the discharge of powder from the powder container 2.

[0041] Furthermore, since the vibration mechanism 16 of this embodiment includes the air vibrator 46 driven by compressed air as a vibration generating source, there is no need to provide a drive source such as a motor in the vibration mechanism 16, and the vibration mechanism 16 is configured to be relatively lightweight. As a result, the powder container 2 can be rotated while the vibration mechanism 16 is attached to the flange portion 32, and there is no need to remove the vibration mechanism 16 from the powder container 2.

[0042] Moreover, in this embodiment, the fixing member 48 includes a strip-shaped member 50 wound around the outer peripheral surface 32b2 of the ring member 32b, the first surface 50a of the strip-shaped member 50 includes a fixing surface 50a1 to which the air vibrator 46 is fixed, and the second surface 50b opposite to the first surface 50a includes an abutment surface that abuts against the outer peripheral surface 32b2, so that the vibration of the air vibrator 46 is propagated around the entire outer peripheral surface 32b2 via the strip-shaped member 50. Furthermore, by winding the strip-shaped member 50 around the outer peripheral surface 32b2, the air vibrator 46 can be fixed to the ring member 32b. Therefore, the vibration mechanism 16 can be easily fixed to the ring member 32b.

[0043] [Regarding the second embodiment] Fig. 5 is a cross-sectional view of a main part of the powder container 2 according to the second embodiment. Fig. 5 is a cross-sectional view including the central axis C2. This embodiment differs from the first embodiment in that the fixing member 48 includes a pair of brackets 60 instead of the belt-shaped member 50, and that an air vibrator 46 is fixed to each of the pair of brackets 60. In other respects, this embodiment is similar to the first embodiment.

[0044] As shown in FIG. 5, the pair of brackets 60 are attached so as to bridge between the flange portion 32 (ring member 32b) and the connection flange portion 17a. The pair of brackets 60 are provided at positions facing each other across the central axis C2 in the circumferential direction of the ring member 32b. The pair of brackets 60 have the same configuration, so the following description will focus on the bracket 60 on the left side in FIG.

[0045] Each bracket 60 is a member formed using a metal plate such as a steel plate or an aluminum alloy, and has a fixing plate 62 and a pair of protruding plate portions 64 . The fixing plate 62 is fixed between the ring member 32b and the connection flange portion 17a. The fixing plate 62 is curved to fit the outer peripheral surface 32b2 of the ring member 32b and the outer peripheral surface 17a1 of the connection flange portion 17a. The air vibrator 46 is fixed to the fixing plate 62. The pair of protruding plate portions 64 protrude radially inward from both axial ends of the fixed plate 62 .

[0046] Fig. 6 is a plan view showing the ring member 32b and the pair of brackets 60. For ease of understanding, Fig. 6 shows only the ring member 32b, the pair of brackets 60, and the pair of air vibrators 46, and omits the powder container 2, the on-off valve 15, the bolts 36, etc. 6 and 5, of the pair of protruding plate portions 64, the protruding plate portion 64 on the ring member 32b side abuts against the side surface 32b3 of the ring member 32b. The side surface 32b3 is the outer surface of the ring member 32b that faces the container body 10. Of the pair of protruding plate portions 64, the protruding plate portion 64 on the connection flange portion 17a side abuts against a side surface 17a2 (FIG. 5) of the connection flange portion 17a. The side surface 17a2 is the outer surface of the connection flange portion 17a that faces the opposite side to the container body 10.

[0047] Further, two slits 66 are provided in each of the pair of protruding plate portions 64. The slits 66 are provided so as to cut out the tip edges 64c of the protruding plate portions 64. Therefore, the slits 66 open radially inward. 6, the slit 66 is provided so that the through-hole 34 is exposed in plan view. Therefore, the bolt 36 can pass through the slit 66. As a result, the protruding plate portion 64 on the ring member 32b side is sandwiched between the head of the bolt 36 and the ring member 32b. Similarly, the protruding plate portion 64 on the connection flange portion 17a side is also sandwiched between the nut 40 and the connection flange portion 17a. Therefore, the bracket 60 is fixed to the flange portion 32 and the connecting flange portion 17a by the bolts 36 and nuts 40.

[0048] In addition, since the slit 66 opens radially inward, after connecting the discharge port 14 and the conveying pipe 17 with the bolt 36 and nut 40, the bracket 60 can be attached from the radially outside of the flange portion 32 and the connecting flange portion 17a.

[0049] As described above, the air vibrator 46 is fixed to the fixing plate 62. The air vibrator 46 is fixed at a position between the ring member 32b and the connection flange portion 17a in the axial direction. The first surface 62a of the fixed plate 62 includes a fixed surface 62a1 to which the air vibrator 46 is fixed. The first surface 62a is a surface of the outer surface of the fixed plate 62 that faces radially outward. Furthermore, the fixing plate 62 is disposed in contact with the outer peripheral surface 32b2 of the ring member 32b and the outer peripheral surface 17a1 of the connection flange portion 17a. Therefore, the second surface 62b of the fixing plate 62 includes an abutment surface 62b1 that abuts the outer peripheral surface 32b2 and an abutment surface 62b2 that abuts the outer peripheral surface 17a1. The second surface 62b is the surface of the outer surface of the fixing plate 62 that faces radially inward.

[0050] In this embodiment, the vibration of the air vibrator 46 is propagated to the outer peripheral surface 32b2 of the ring member 32b via the fixing plate 62. Furthermore, the protruding plate portions 64 on both ends of the fixing plate 62 can be clamped by the bolts 36 and the nuts 40, and the fixing plate 62 can be firmly fixed to the ring member 32b.

[0051] 〔others〕 It should be noted that the embodiments disclosed herein are to be considered as illustrative in all respects and not restrictive. In the above embodiments, the air vibrator 46 is used as the vibration generating source. However, a vibrator that has a built-in motor or the like and generates vibrations using electricity may also be used as the vibration generating source. Furthermore, in the first embodiment, the case where one air vibrator 46 is provided on the belt-shaped member 50 is exemplified, but a plurality of air vibrators 46 may be provided on the belt-shaped member 50. Furthermore, in the above second embodiment, the fixing member 48 includes two brackets 60 and two air vibrators 46, but the fixing member 48 may include at least one bracket 60 and one air vibrator 46. Furthermore, in each of the above embodiments, the air vibrator 46 is fixed to the ring member 32b of the flange portion 32 by the fixing member 48, and vibration is applied to the flange portion 32. However, the air vibrator 46 may be provided at the discharge port 14 and configured to be able to apply vibration to the discharge port 14. Therefore, the air vibrator 46 may be fixed to the tubular portion 30 of the discharge port 14.

[0052] The scope of the present invention is defined by the claims, not by the meaning described above, and is intended to include meanings equivalent to the claims and all modifications within the scope thereof. [Explanation of symbols]
