Description

  The present invention relates to a dryer used in a process of heating and drying a wood chip as a raw material for particle board.

  Various types of wood chip dryers that serve as raw materials for particle boards have been proposed. As dryers related to the present invention, for example, dryers as shown in FIGS. 10 and 11 are used. There are 900. The dryer 900 includes a casing 90 installed at a predetermined location, a substantially cylindrical rotating shaft 91 in which the shaft center 91 c is disposed substantially horizontally in the casing 90, and a shaft center around the rotating shaft 91. A plurality of heating pipes 92 that are parallel to and concentrically arranged with 91c, a plurality of support members 93 that are arranged radially on the outer periphery of the rotary shaft 91 to hold these heating pipes 92, and And a stirring blade 94 provided on the outer peripheral side.

  An exhaust duct 99 is connected to the upper portion of the casing 90 in a communicating state, and a filter 99 a is disposed in the middle of the exhaust duct 99. The rotary shaft 91 is formed of a cylindrical body in which a main body portion 97 located in the casing 90 is formed with a plurality of through holes 98 formed in a peripheral wall, and a cylindrical drive shaft portion 91a and a driven shaft are provided at both ends of the main body portion 97, respectively. A portion 91b is provided.

  Steam (about 170 ° C.) was supplied into the plurality of heating pipes 92 via the drive shaft portion 91 a to heat the ambient temperature in the casing 90 to about 110 ° C., so that it was charged into the casing 90. Dry wood chips, etc. In addition, air (normal temperature) is supplied from the driven shaft portion 91 b into the main body portion 97, and this air is blown into the casing 90 from the plurality of through holes 98, and is discharged into the casing 90 together with dust floating in the casing 90. It is discharged to the outside via. Dust in the air flowing into the exhaust duct 99 is captured by the filter 99a, and the air that has passed through the filter 99a is discharged to the outside after passing through a predetermined processing step.

  In the dryer 900, the reason why the inside of the casing 90 is indirectly heated by the steam supplied into the heating pipe 92 is that if the wood chip is directly heated with a heater or the like, it may ignite. This is to avoid this.

  Further, in the dryer 900, in consideration of the difference in expansion and contraction due to the temperature difference between the rotating shaft 91 and the heating pipe 92, as shown in FIGS. 12 (a) and 13 (a), the rotating shaft 91 The outer periphery and the base end portion 93 a of the support member 93 (the portion near the axis 91 c shown in FIG. 10) are held so as to be slidable with each other via the sliding member 95 and the slider 96. The sliding member 95 is fixed to the outer periphery of the rotary shaft 91, and the slider 96 is fixed to the base end portion 93 a of the support member 93. Since the sliding member 95 and the slider 96 are slidable in the circumferential direction and the axial center 91c direction of the rotary shaft 91, it is possible to cope with a deviation during expansion and contraction of the rotary shaft 91 and the heating pipe 92.

  On the other hand, although the technical field is slightly different from the present invention, as a conventional rotary dryer, for example, “indirect heating type rotary dryer” is disclosed in Patent Document 1, and “powder” is disclosed in Patent Document 2. An indirect heating rotary dryer for granules is disclosed.

JP 2003-16898 A JP-A-4-345687

  In the conventional dryer 900 shown in FIG. 10, as shown in FIGS. 12A and 13A, the outer periphery of the rotary shaft 91 and the base end portion 93 a of the support member 93 are slidable members 95. And a slider 96 so as to be slidable with respect to each other. For this reason, when the dryer 900 is operated for a long time, the slider 96 wears away or slides as shown in FIGS. 12B and 13B due to repeated sliding during expansion and contraction. There are frequent occurrences of dents due to wear on the surface 95 (the surface on which the slider 96 slides). When the sliding member 95 and the slider 96 are in the state as shown in FIG. 12B and FIG. 13B, the support function of the plurality of heating pipes 92 by the support member 93 is lowered, causing various troubles. Become.

  Further, when the support function of the plurality of heating pipes 92 by the support member 93 is lowered, the plurality of heating pipes 92 arranged around the rotating shaft 91 are bent in the direction of gravity as shown in FIG. 94 may contact the inner peripheral surface of the casing 90 (see FIG. 10), and the stirring blade 94 and the inner peripheral surface of the casing 90 may be damaged.

  As described above, when the sliding member 95 and the slider 96 are worn, it is necessary to stop the operation of the dryer 900 and perform maintenance such as parts replacement and repair before a serious accident occurs. However, since these maintenance operations must be performed by removing the entire rotary shaft 91 and the plurality of heating pipes 92 from the casing 90 using a lifting machine, not only a great deal of labor and time is required, but also a dryer. A decrease in the operating rate of 900 causes a reduction in production efficiency. Such a problem is difficult to solve even if the inventions described in Patent Documents 1 and 2 are used.

  The problem to be solved by the present invention is to provide a dryer with few failures due to wear of parts and good maintainability.

  The dryer of the present invention includes a rotating shaft disposed in a substantially horizontal direction in a casing, a support member disposed on an outer periphery of the rotating shaft to support a heating member arranged around the rotating shaft, A rotating body interposed between the support member and an outer periphery of the rotary shaft so as to be able to move in order to hold the support member movably in the axial direction of the rotary shaft;

  With this configuration, the supporting member of the heating member and the outer periphery of the rotating shaft are held so as to be movable in the axial direction of the rotating shaft through the rolling of the rotating body. A shift in the axial direction due to the difference in the amount of expansion and contraction of the shaft is absorbed by the rolling of the rotating body. Thereby, since the friction between the supporting member of a heating member and the outer periphery of a rotating shaft can be eliminated, the failure resulting from component wear is significantly reduced. In addition, since the failure due to component wear that requires large-scale component replacement work is reduced, the maintainability is also improved.

  Here, it is desirable to provide a restricting means for specifying the moving direction of the rotating body in a direction parallel to the axis of the rotating shaft. With such a configuration, movement of the rotating body in a direction other than the axial center direction of the rotating shaft is prevented, so that not only the moving of the rotating body in the axial direction becomes smooth, but also the rotating shaft rotates in the circumferential direction. Wear caused by the movement of the body can be prevented.

  Moreover, it is desirable that the rotating body is detachably attached to the support member. With such a configuration, even if the rotating body is worn due to the long-time operation of the dryer according to the present invention, it can be easily dealt with by replacing the parts of the rotating body, so that the maintainability is further improved. improves.

  On the other hand, a bush that can slide with at least one of the heating member and the support member can be interposed. With such a configuration, wear of the heating member due to friction between the heating member and the support member due to repeated expansion and contraction can be reduced.

  Further, the heating member can be provided with a connecting means that can be connected and separated. With such a configuration, when trouble occurs in or damage to a part of the heating member during operation of the dryer, a part of the heating member is released by releasing the connecting means in the vicinity of the part. As a result, it is possible to replace only the gas, and the maintainability is further improved.

  In addition, a roller is provided on the support member as the rotating body, and as the restricting means, a rail disposed on the outer periphery of the rotating shaft in parallel with the axial direction of the rotating shaft, and a moving direction of the roller is set on the rail. It is desirable to provide a flange formed on the roller for restraining in the longitudinal direction. With this configuration, the roller is held so as to be movable only in the axial direction of the rotating shaft along the rail, so that the roller moves smoothly and prevents wear caused by the roller moving in directions other than the rail direction. can do.

  In addition, it is desirable that the roller can be separated from the rail when the roller receives a force in a direction away from the axis of the rotating shaft. With such a configuration, when the roller is positioned below the axis of the rotating shaft as the rotating shaft rotates, the roller moves away from the axis of the rotating shaft due to gravity acting on the heating member or the support member. When the force is applied, the roller is separated from the rail and a gap is formed between them, so that the wood chip strips and dust interposed between the roller and the rail can be separated. For this reason, it is possible to avoid various troubles caused by wood chip strips that are pinched or accumulated between the roller and the rail during operation of the dryer.

  According to the present invention, it is possible to provide a dryer with few failures due to component wear and good maintainability.

  Hereinafter, the dryer 100 which is embodiment of this invention is demonstrated based on FIGS. The dryer 100 is arranged around the rotary shaft 13 and a cylindrical rotary shaft 13 arranged in a substantially horizontal direction in a casing 12 arranged on a foundation structure 11 constructed on a predetermined installation surface 10. A plurality of support members 15 arranged radially on the outer periphery of the rotary shaft 13 to support the plurality of heating pipes 14 as heating members, and these support members 15 are movable in the direction of the axis 13c of the rotary shaft 13. A roller 16 that is a rotating body is provided between the base end portion 15a of the support member 15 and the outer periphery of the rotary shaft 13 so as to be held.

  An exhaust duct 25 is connected to the upper part of the casing 12 in a communicating state, and a filter 26 is disposed in the middle of the exhaust duct 25. The rotating shaft 13 is formed of a cylindrical body having a body portion 13d located in the casing 12 and having a plurality of through holes 13g formed in a peripheral wall 13f, and a cylindrical drive shaft portion 13a and a driven body at both ends of the body portion 13d. A shaft portion 13b is provided.

  Water vapor (about 170 ° C.) is supplied into the plurality of heating pipes 14 via the drive shaft portion 13 a of the rotating shaft 13 to heat the atmospheric temperature in the casing 12 to about 110 ° C., and is charged into the casing 12. Dried wood chips etc. are dried. Further, air (normal temperature) supplied from the driven shaft portion 13b of the rotating shaft 13 into the main body portion 13d is blown radially into the casing 12 through the plurality of through holes 13g, and exhausted together with dust floating in the casing 12. It is discharged to the outside via the duct 25. Dust contained in the air flowing into the exhaust duct 25 is captured by the filter 26, and the air that has passed through the filter 26 is discharged to the outside after passing through a predetermined processing step.

  In this way, the high-temperature water vapor fed from the outside via the main shaft 13 a of the main body 13 d of the rotary shaft 13 is caused to flow in the heating pipe 14 to increase the temperature in the casing 12, and together with the rotary shaft 13. While the support member 15 and the heating pipe 14 are rotated, the drying operation of the wood chips and the like put into the casing 12 is performed.

  The plurality of heating pipes 14 are arranged so as to be positioned on a plurality of virtual concentric circles that are parallel to the direction of the axis 13 c of the rotating shaft 13 and coaxial with the rotating shaft 13. As shown in FIGS. 2 and 5, the plurality of support members 15 are arranged at equal intervals along a virtual concentric circle surface coaxial with the axis 13 c of the rotary shaft 13 so as to be radially centered on the axis 13 c. The adjacent support members 15 are connected to each other by a plurality of connecting members 17a and 17b, whereby a spider web-like radial structure 18 is formed. The connecting member 17a is disposed at a position near the base end portion 15a (the shaft center 13c) of the support member 15, and the connecting member 17b is disposed at a position near the distal end portion 15b of the support member 15 (closer to the casing 12).

  Although an even number of the plurality of support members 15 forming the radial structure 18 are arranged, the base end portions 15 a of all the support members 15 are not arranged on the outer periphery of the rotating shaft 13 via the rollers 16. . That is, as shown in FIGS. 2 and 5, the roller 16 is interposed between the base end portion 15 a of every other support member 15 and the outer periphery of the rotating shaft 13 along the circumferential direction of the rotating shaft 13. . Further, as shown in FIG. 1, the radial structures 18 are arranged at a plurality of locations separated in the direction of the axis 13 c of the rotating shaft 13. A long reinforcing member 19 having a U-shaped cross section is fixed to the distal end portion 15b of the support member 15 forming each radial structure 18 in a state of being parallel to the rotary shaft 13.

  As shown in FIGS. 3 to 6, a base portion 15 a of the support member 15 is attached with a carriage portion 20 having a support shaft 21 that rotatably supports the roller 16, and a pedestal 22 is interposed on the outer periphery of the rotation shaft 13. The rollers 16 are on the rails 23 attached in this manner. Both ends of the roller 16 are provided with flanges 16a having an enlarged diameter, and the roller 16 rides on the rail 23 with the rail 23 being straddled between the pair of flanges 16a. Since the shaft center 21c of the support shaft 21 of the roller 16 is arranged so as to three-dimensionally intersect the shaft center 13c of the rotating shaft 13 in the direction of 90 degrees, the roller 16 can roll only in the axis direction 13c of the rotating shaft 13. It is.

  The rail 23 is detachably attached to the pedestal 22 using screws (not shown), and the carriage unit 20 is detachably attached to the base end portion 15a of the support member 15 using screws (not shown). . The roller 16 and the support shaft 21 are also detachably attached to the carriage unit 20.

  As shown in FIGS. 4 and 6, the plurality of heating pipes 14 are attached in a state of passing through a plurality of openings 15 c opened in the support member 15 in parallel with the axis 13 c (see FIG. 1) of the rotary shaft 13. A bush 24 slidable with at least one of the openings 15 c and the outer periphery of the heating pipe 14 is fitted. The bush 24 has a short cylindrical shape through which the heating pipe 14 can pass, and has a flange-shaped portion 24a having an enlarged diameter at one end thereof.

  In the dryer 100, the support member 15 of the heating pipe 14 and the outer periphery of the rotary shaft 13 are held so as to be movable in the direction of the axis 13 c of the rotary shaft 13 via a rotatable roller 16. 14 and the shaft 13c in the direction of the axis 13c due to the difference in expansion and contraction between the rotary shaft 13 and the roller 16 are absorbed. Therefore, no sliding friction occurs between the support member 15 of the heating pipe 14 and the outer periphery of the rotary shaft 13, and the failure due to component wear is greatly reduced. In addition, since the failure due to wear of parts that requires a large part replacement work is reduced, the maintainability is also good.

  Further, even if a piece of wood chip or dust, which is an object to be dried, is caught between the roller 16 and the rail 23, the roller 16 is easily detached and does not accumulate. Further, the wood chip strips sandwiched between the roller 16 and the rail 23 are not subjected to friction even though they are pressed between the two, so that the wood chip strips are generated by frictional heat. It does not ignite and has excellent safety.

  Further, as a restricting means for specifying the moving direction of the roller 16 in a direction parallel to the axis 13c of the rotating shaft 13, both side edges of the rail 23 are sandwiched between the rail 23 and the roller 16 rolling on the rail 23. A flange 16a is formed as described above. As a result, the rolling movement of the roller 16 in the direction other than the direction of the axis 13c of the rotating shaft 13 is prevented, so that the rolling movement of the roller 16 in the direction of the axis 13c is not only smooth, but also the circumference of the rotating shaft 13 Wear caused by the movement of the roller 16 in the direction can be prevented.

  Further, the rail 23 can be attached to and detached from the pedestal 22, the carriage unit 20 can be attached to and detached from the base end portion 15 a of the support member 15, and the roller 16 and the support shaft 21 can also be attached to and detached from the carriage unit 20. Even when the roller 16 and the rail 23 are worn when the 100 is operated for a long time, it can be easily dealt with by exchanging parts of the roller 16 and the rail 23, which is effective in improving the maintainability.

  On the other hand, as shown in FIGS. 4 and 6, since a slidable bush 24 is interposed between the heating pipe 14 and the support member 15, the heating pipe 14 and the support member 15 are repeatedly formed by repeated expansion and contraction. Wear of the heating pipe 14 due to friction can be reduced. The bushing 24 is preferably made of heat-resistant bronze, but is not limited thereto.

  Next, based on FIG. 7, when the dryer 100 shown in FIG. 1 is operating, the support member 15 that rotates together with the rotating shaft 13 in the casing 12, the roller 16 attached to the base end portion 15, and the like. The state will be described.

  As shown in FIGS. 1 and 2, the plurality of heating pipes 14 arranged around the rotary shaft 13 are supported by a plurality of support members 15 and the like, but when viewed as a whole, in the direction of gravity (vertical direction). As the rotary shaft 13 rotates, when the support member 15 is positioned directly above the axis 13c of the rotary shaft 13, the support member 15 receives a force in a direction approaching the axis 13c of the rotary shaft 13. The support member 15 positioned directly below the axis 13c of the rotary shaft 13 receives a force in a direction away from the axis 13c of the rotary shaft 13.

  Accordingly, a force in a direction approaching the shaft center 13c is applied to the roller 16 provided on the support member 15 positioned directly above the shaft center 13c, and the roller 16 provided on the support member 15 positioned directly below the shaft center 13c. A force in a direction away from the axis 13c is applied to the roller 16, but the dryer 100 can separate the roller 16 from the rail 23 when the roller 16 receives a force in a direction away from the axis 13c of the rotating shaft 13. Since the structure is provided, the roller 16 can be brought into close contact with or separated from the rail 23 depending on the direction of the force applied to the roller 16.

  That is, as shown in FIG. 7A, when the roller 16 is positioned right above the axis 13c of the rotary shaft 13, when the force in the direction approaching the axis 13c is applied to the roller 16, the roller 16 Since the roller 16 is pressed toward the rail 23, the roller 16 is in close contact with the rail 23.

  Further, as shown in FIG. 7C, when the roller 16 is positioned directly below the axis 13c of the rotating shaft 13, when the force in the direction away from the axis 13c is applied to the roller 16, the roller 16 moves to the rail. 23, a gap G is generated between the roller 16 and the rail 23.

  On the other hand, as shown in FIGS. 7B and 7D, when the roller 16 is positioned at the same height as the axis 13 c of the rotating shaft 13, the roller 16 is directed downwardly parallel to the support shaft 21. As the force is applied, the roller 16 moves slightly downward. However, the support member 15 to which the roller 16 is attached is connected to the adjacent support members 15 as shown in FIG. The flanges 16a of the rollers 16 are kept out of contact with the rails 23.

  Thus, in the dryer 100, when the roller 16 receives a force in a direction away from the axis 13 c of the rotating shaft 13, the roller 16 is separated from the rail 23, and a gap G is generated between them. It is possible to remove the wood chip strips, dust and the like interposed between the rail 23 and the rail 23. For this reason, during operation of the dryer 100, it is possible to avoid a trouble that a piece of wood chip sandwiched between the roller 16 and the rail 23 is ignited by frictional heat.

  Next, based on FIG. 8, other embodiment regarding heating piping is described. In the embodiment shown in FIG. 8, a flange joint 30 is provided as a connecting means that can be connected and separated to a plurality of heating pipes 14 supported by a support member (none of which is shown) around the rotating shaft. Yes. Each flange joint 30 is detachably connected by a plurality of screws (not shown). In order to avoid contact between the flange joints 30, the flange joints 30 are arranged so that the flange joints 30 of adjacent heating pipes 14 form a staggered shape.

  With the configuration as shown in FIG. 8, when trouble occurs or damages to a part of the heating pipe 14 during operation of the dryer, by separating the flange joint 30 in the vicinity of the part, Since only a part of the heating pipe 14 can be replaced, the maintainability is further improved.

  In addition, since the connection means which can separate and connect the heating pipe 14 is not limited to the flange joint 30, for example, clamp joints 40 and 50 as shown in FIGS. 9A and 9B are employed as other connection means. You can also.

  A clamp joint 40 shown in FIG. 9A includes a band-shaped housing 41 that can open and close a connecting portion of the heating pipe 14, a sealing material 42 disposed on the inner peripheral surface of the housing 41, and an opening of the housing 41. A pair of rods 43a and 43b attached along the end edges 41a and 41b, and a plurality of bolts 44 for opening and closing the opening end edges 41a and 41b by detachably connecting the rods 43a and 43b. I have. In the housing 41, a plurality of hinge portions 41b are provided in regions facing the opening end edges 41a and 41b.

  When the bolt 44 is loosened and its tip 44a is detached from the rod 43a on the opening edge 41a side, the opening edges 41a and 41b can be opened and closed with the hinge portion 41c as a curved portion. If it opens, the clamp joint 40 can be attached or detached to the outer periphery of the connection part of the heating pipe 14. Moreover, if the front-end | tip part 44a of the volt | bolt 44 is screwed together and fastened to the rod 43a, the connection part of the heating piping 14 can be connected airtightly. Although the position of the connection part of the heating piping 14 by the clamp joint 40 is not limited, For example, like the flange joint 30 shown in FIG. 8, it can arrange | position so that a zigzag shape may be made.

  A clamp joint 50 shown in FIG. 9 (b) includes a pair of arcuate housings 51x and 51y that grips a connecting portion of the heating pipe 14 so as to be openable and closable, and a sealing material 52 disposed on the inner peripheral surface of the housings 51x and 51y. The rods 53xa, 53xb, 53ya, 53yb attached along the opening edges 51xa, 51xb, 51ya, 51yb of the housings 51x, 51y, and the bolts x and the rods 53xb for detachably connecting the rods 53xa, 53ya to each other. And a bolt y for detachably connecting 53yb.

  When at least one of the bolts 54x and 54y is loosened and the tip 54xa (or 54ya) is detached from the rod 53xa (or 53xb) on the opening edge 51xa (or 51xb) side, the opening edge 51ax, 51ya (or 51xb) , 51yb) can be opened and closed, and the clamp joint 50 can be attached to and detached from the outer periphery of the connecting portion of the heating pipe 14 by opening the opening ends 51ax, 51ya (or 51xb, 51yb). Further, when the tip 54xa of the bolt 54x (tip 54ya of the bolt 54y) is screwed into the rod 53xa (or 53xb) and tightened, the connecting portion of the heating pipe 14 can be connected in an airtight manner.

  In addition, when both the bolts 54x and 54y are loosened and the tips 54xa and 54ya are detached from the rods 53xa and 53xb on the opening end edges 51xa and 51xb side, the housings 51x and 51y can be separated. Thus, the clamp joint 50 can be attached to and detached from the outer periphery of the connection portion of the heating pipe 14. Although the position of the connection part of the heating piping 14 by the clamp joint 50 is not limited, For example, like the flange joint 30 shown in FIG. 8, it can arrange | position so that a zigzag shape may be made.
