Description

  The present invention relates to a chimney curing lid structure for diffusing exhaust gas discharged from, for example, an incinerator or the like into the atmosphere.

In general, a chimney of an incinerator or the like operates a plurality of installed garbage incinerators according to a certain operation rotation. At this time, rainwater entered from the chimney where the operation was stopped, and there was a risk that rust and corrosion would occur.
Therefore, a configuration in which a cap is manually attached to the top of the chimney that has stopped operation, or a configuration in which the chimney is covered with a shutter-like lid that opens and closes horizontally as shown in Citation 1, and a configuration in which a flat lid is opened and closed Things have been proposed.
JP-A-10-160154

However, in the conventional chimney multi-cylinder curing lid structure having such a configuration, if a shutter-like lid is installed in each chimney, the apparatus is complicated and easily damaged, and the apparatus becomes large.
Further, in the case of manually opening and closing the lid, it is difficult to attach or remove heavy lids to a plurality of chimneys by one person, and there is a possibility that there is a risk.

  This invention has been proposed in view of the above, and an operator can selectively cover a plurality of chimneys when operation is stopped alone to prevent intrusion of rainwater, etc., thereby preventing rust and corrosion inside the chimneys. It aims at providing the curing lid structure for chimney multicylinders which can prevent generation | occurrence | production and can prevent the oxide in a chimney from scattering to circumference | surroundings.

  In order to achieve the above object, a multi-cylinder curing lid structure of the present invention is a multi-cylinder curing lid structure that is disposed so as to be able to open and close the smoke exhaust openings of a plurality of chimneys. An arm mechanism disposed at an equal distance from the center of the chimney, and a lid that is attached to a tip of the arm mechanism and selectively closes the plurality of chimneys, and the arm mechanism is erected on a base floor A support column that is swingably and pivotably supported by the support column, and that holds the lid body in a detachable manner, a counter balance that is attached to one end of the arm and is substantially balanced with the lid body, It has a winch for raising and lowering the tip.

  In the present invention, the lid is connected to the tip of the arm at an eccentric position.

  Since this invention consists of an above-described structure, there can exist an effect which is demonstrated below.

  In the present invention, a chimney multi-cylinder curing lid structure disposed so as to be able to open and close the smoke exhaust openings of a plurality of chimneys, the arm mechanism disposed at an equal distance from the center of the plurality of chimneys, A lid that is attached to the tip of the arm mechanism and selectively closes the plurality of chimneys, and the arm mechanism is supported upright on a base floor and swingable and rotatable on the support column. A chimney that has stopped operation because it includes an arm that detachably holds the lid, a counter balance that is attached to one end of the arm and is substantially balanced with the lid, and a winch that raises and lowers the tip of the arm. In addition, the curing lid can be selectively closed to prevent intrusion of rainwater and rust inside the chimney. In addition, the operation can be performed safely as compared with the case where the lid is operated manually. Further, if the work is performed with the winch, one person can perform the opening and closing work.

  In the present invention, since the lid is connected to the arm tip at an eccentric position, the lid is pressed by the arm tip when the lid is closed, so that it is possible to prevent the lid from being inadvertently opened by wind or the like. . In particular, the lid is difficult to open because it is attached to the arm at a position eccentric to the opposite side to the locking means installed on the lid. The winch can be safely opened and closed by one person.

  A chimney multi-cylinder curing lid structure, comprising an arm mechanism disposed at an equal distance from the center of a plurality of chimneys, and a lid attached to the tip of the arm mechanism and selectively closing the plurality of chimneys, The arm mechanism includes a support column, an arm that is swingably and pivotably supported by the support column, an arm that detachably holds the lid, a counterbalance that is substantially balanced with the lid, and a winch that lifts and lowers the tip of the arm. The purpose of selectively opening and closing a plurality of chimneys by one worker can be achieved.

  Hereinafter, the present invention will be described in detail with reference to the drawings illustrating an embodiment. FIG. 1 is a perspective view showing a state in which both chimneys are opened in the chimney multi-cylinder curing lid structure according to the present invention, and FIG. 2 shows a state in which both chimneys are opened in the chimney multi-cylinder curing lid structure of the present invention. FIG. 3 is a side view, and FIG. 3 is a plan view showing a state where the chimney is opened. Here, the chimney multi-cylinder curing lid structure 10 is disposed such that the smoke exhaust openings 12 of the plurality of chimneys 11 can be opened and closed, and is disposed at an equal distance from the center C of the plurality of chimneys 11. An arm mechanism 13, and a lid 14 that is attached to the tip of the arm mechanism and selectively closes the plurality of chimneys.

  As shown in FIG. 3, in this embodiment, the arm mechanism 13 is disposed at an equal distance from the center C of the two chimneys 11, and the lid 14 can be attached to both chimneys with one arm. . The arm mechanism 13 includes a support column 15 erected on the base floor, an arm 16 supported on the support column 15 so as to be swingable and rotatable, and a detachable holder for holding the lid body 14. A counter balance 17 that is attached to one end and is substantially balanced with the lid body 14 and a winch 18 that lifts and lowers the tip of the arm 16 are provided.

  The support column 15 is erected from the base floor and supported by the wall surface by the support 19. Further, a manual winch 18 and a turning handle 20 are attached to the support column 15 and are supported so as to be rotatable with respect to a base end portion 15a fixed to the base floor. The winch 18 can swing the arm 16 by loosening or winding the wire 21 with the handle 18a. In the turning handle 20, rod-shaped arms protrude in the radial direction at 90 ° intervals, and the support column 15 and the arm 16 can be turned by holding the arms.

  The arm 16 is pivotally supported on the top of the support column 15 by a fulcrum 16a, and is biased in a direction in which the tip end side for attaching the lid body 14 to the spring 22 fixed to the support column 15 is lowered. A counter balance 17 that is substantially balanced with the lid 14 is attached to the base end side of the arm 16. The weight of the counter balance 17 is determined by the position of the fulcrum 16a with respect to the arm and the weight of the lid 14. Further, one end of the wire 21 is fixed to the proximal end side of the arm 16.

  The distal end side of the arm 16 is bent into a bowl shape, and an attachment piece 16b for attaching the lid body 14 is formed at the distal end portion. Bolt holes for inserting the locking bolts 23 are formed in the mounting pieces 16b (see FIG. 6). The lid 14 is connected to the mounting piece 16b through a locking bolt 23 so as to be swingable.

  The lid body 14 has a size covering the smoke exhaust opening 12 of the chimney and is formed in a substantially disc shape, and has a projection 24 for suspension at the upper end. The lid 14 has a locking protrusion 25 at the tip, and engages with a locking piece 27 formed on the top nozzle trap 26 formed on the chimney 11 side. The locking protrusions 25 and the locking pieces 27 are fixed by inserting the locking bolts into the formed bolt holes. Further, the protrusion 24 has a hanging bolt hole and is eccentric in the opposite direction to the locking protrusion 25 by X from the center C as shown in FIG.

  FIG. 7 is a main part plan view showing a detachment preventing mechanism in the chimney multi-cylinder curing lid structure, and FIG. 8 is a main part side view thereof. In the locking mechanism, a locking plate 28 is formed on the lower edge of the lid body 14 in the direction opposite to the locking projection piece 25. The stopper plate 28 is installed so as to engage with a protrusion 29 formed on the outer edge near the top of the chimney 11 when the lid 14 is mounted.

  Next, operation | movement of the curing lid structure for chimney multicylinders comprised as mentioned above is demonstrated. First, when operating both incinerators etc., as shown in FIGS. 1 and 2, both the chimneys 11 are open, and the lid 14 is removed from the arm mechanism 13 and placed on the base floor. . The arm mechanism 13 also lowers the arm 16 so as not to be affected by wind or the like.

  Next, when the operation of any chimney 11 is stopped and the lid body 14 is closed, the lid body 14 is first attached to the tip of the arm 16 of the arm mechanism 13. After attaching the lid 14, the arm 16 is raised by turning the handle 18 a of the winch 18, and the lid 14 is raised above the chimney 11. Thereafter, the swivel handle 20 is held and swung on the chimney to be covered (see FIGS. 3 and 4). When the lid body 14 comes directly above the smoke exhaust opening 12 of the chimney, the locking projection piece 25 and the locking piece 27 are lowered so as to coincide with each other, and the locking plate 28 and the protruding portion 29 are engaged. Finally, the worker ascends the top nozzle trap 26 of the chimney 11 and fixes the locking protrusions 25 and the locking pieces 27 with locking bolts. In this state, the lid body 14 is fixed by the detachment prevention plate 28, the locking protrusion 25, and the locking piece 27, and is pressed by the arm 16 biased downward by the spring 22. Therefore, the lid 14 can be firmly fixed and is safe.

  When the other chimney 11 is covered, the operator ascends the top nozzle trap 26 and removes the locking bolts for fixing the locking protrusions 25 and the locking pieces 27, and then turns to the arm mechanism 13 side. Then, it is lifted by the winch 18 and swung by the turning handle 20. The locking projection piece 25 and the locking piece 27 are fixed with locking bolts after the release plate 28 is lowered and engaged with the protruding portion 29 just above the predetermined chimney 11. In this way, the desired chimney 11 can be covered and fixed by the lid 14.

  Thus, in the curing lid structure for a chimney multi-cylinder of the present invention, even if the lid 14 is heavy, the winch 18 can be used to easily open and close alone. In addition, it is possible to prevent the intrusion of rainwater by covering only the chimney whose operation is stopped in the plurality of chimneys, and to prevent the rust inside the chimney. Moreover, it is possible to prevent the oxide in the chimney from being scattered around.

  In addition, although the above example demonstrated the case where there were two chimneys, a lid body can be similarly installed even if it is three or more.
