Description

本開示は、対象物に付着した付着物を打撃振動により除去するためのハンマリング装置、該ハンマリング装置を備える排熱回収装置、に関する。   The present disclosure relates to a hammering device for removing deposits attached to an object by striking vibration, and an exhaust heat recovery device including the hammering device.

例えばセメント焼成プラントなどの高温の排ガスが排出される燃焼機関には、上記排ガスから熱を回収するための排熱ボイラ（排熱回収装置）が設けられることがある。排熱ボイラは、発電などに用いるための蒸気や温水を発生させるための伝熱管がケーシングの内部に配置されている。排ガスボイラは、ケーシングの内部に導入された排ガスから伝熱管内の媒体に熱を伝達させることで、上記排ガスから熱を回収するように構成される。   For example, a combustion engine that discharges high-temperature exhaust gas such as a cement firing plant may be provided with an exhaust heat boiler (exhaust heat recovery device) for recovering heat from the exhaust gas. In the exhaust heat boiler, a heat transfer tube for generating steam or hot water for use in power generation or the like is disposed inside the casing. The exhaust gas boiler is configured to recover heat from the exhaust gas by transferring heat from the exhaust gas introduced into the casing to the medium in the heat transfer tube.

上記排ガスは、煤塵などの伝熱管の表面に付着する付着物を含んでいる。上記付着物が伝熱管に堆積すると、排ガスと伝熱管内の媒体との間での熱伝達が阻害されて排熱ボイラの熱交換効率が低下する虞がある。このため、排熱ボイラには、伝熱管に打撃振動を与えて伝熱管の表面に付着した付着物を除去するハンマリング装置が搭載されることがある（例えば、特許文献１参照）。   The exhaust gas contains deposits such as dust that adhere to the surface of the heat transfer tube. If the deposits accumulate on the heat transfer tubes, heat transfer between the exhaust gas and the medium in the heat transfer tubes may be hindered, and the heat exchange efficiency of the exhaust heat boiler may be reduced. For this reason, the exhaust heat boiler may be equipped with a hammering device that applies striking vibration to the heat transfer tube to remove deposits attached to the surface of the heat transfer tube (see, for example, Patent Document 1).

特許文献１には、伝熱管に結合される連結軸と、上記連結軸のボイラ外殻壁から突出した先端に衝撃力を吸収するための弾性体を介して結合されるラッピングロッドと、上記ラッピングロッドの被打撃部に打撃を加えるエアノッカー（打撃装置）と、を備えるハンマリング装置が開示されている。エアノッカーによりラッピングロッドに打撃を加えることで、伝熱管に打撃振動を与えることができる。   Patent Document 1 discloses a connecting shaft that is coupled to a heat transfer tube, a wrapping rod that is coupled to an end of the coupling shaft that protrudes from the outer shell wall of the boiler via an elastic body for absorbing impact force, and the wrapping described above. A hammering device is disclosed that includes an air knocker (striking device) for striking a hit portion of a rod. By striking the wrapping rod with an air knocker, striking vibration can be applied to the heat transfer tube.

特許第５５９６２０９号公報Japanese Patent No. 5596209

特許文献１に記載のハンマリング装置では、エアノッカーからラッピングロッドの被打撃部に打撃が加えられると、ラッピングロッドが結合された弾性体や連結軸と一緒に揺れ動く。上記ハンマリング装置には、ラッピングロッドの揺れを抑えるような機構が設けられていないので、ラッピングロッドの揺れが収まり静止するまでに時間がかかるという問題がある。   In the hammering device described in Patent Document 1, when an impact is applied from the air knocker to the hit portion of the wrapping rod, the hammering device swings together with the elastic body and the connecting shaft to which the wrapping rod is coupled. Since the hammering device is not provided with a mechanism for suppressing the swing of the wrapping rod, there is a problem that it takes time until the swing of the wrapping rod is settled and stops.

エアノッカーがラッピングロッドに再度打撃を加える際に、ラッピングロッドが静止状態における初期位置に戻り静止していないと、エアノッカーから打撃される被打撃部の被打撃位置が、前回の被打撃位置からずれるため、エアノッカーからラッピングロッドに伝達される打撃力にばらつきが生じる虞がある。エアノッカーからラッピングロッドに伝達される打撃力が安定しないと、伝熱管に与えられる打撃振動が不十分なことがあるため、伝熱管に付着した付着物が除去されずに堆積する虞がある。   When the air knocker hits the wrapping rod again, if the wrapping rod returns to the initial position in the stationary state and does not stop, the hit position of the hit part hit by the air knocker will deviate from the previous hit position. There is a risk that the striking force transmitted from the air knocker to the wrapping rod will vary. If the striking force transmitted from the air knocker to the wrapping rod is not stable, the striking vibration applied to the heat transfer tube may be insufficient, and there is a risk that deposits adhering to the heat transfer tube will accumulate without being removed.

上述した事情に鑑みて、本発明の少なくとも一実施形態の目的は、被打撃部に伝達される打撃力のばらつきを抑制して、被打撃部に伝達される打撃力を安定させることができるハンマリング装置を提供することにある。   In view of the circumstances described above, an object of at least one embodiment of the present invention is to provide a hammer capable of stabilizing the hitting force transmitted to the hit part by suppressing variations in hitting force transmitted to the hit part. It is to provide a ring device.

（１）本発明の少なくとも一実施形態にかかるハンマリング装置は、

A biasing member configured to bias the striking force transmission shaft so that the striking force transmission shaft returns to an initial position in a stationary state;
A reaction force receiving member provided immovably with respect to the movement of the striking force transmission shaft and configured to receive a reaction force of the biasing member.

上記（１）の構成によれば、ハンマリング装置は、打撃力伝達軸が静止状態における初期位置に戻るように打撃力伝達軸を付勢するように構成された付勢部材と、打撃力伝達軸の移動に対して不動に設けられるとともに、付勢部材の反力を受けるように構成された反力受部材と、を備える。ここで、「打撃力伝達軸の移動に対して不動に設けられる」とは、打撃力伝達軸が打撃力を伝達する際の移動に応じて移動することなく、反力受部材の位置が変化しないことを意味する。   According to the configuration of (1) above, the hammering device includes an urging member configured to urge the striking force transmission shaft so that the striking force transmission shaft returns to the initial position in the stationary state, and the striking force transmission. And a reaction force receiving member provided immovably with respect to the movement of the shaft and configured to receive a reaction force of the urging member.

It means not.

打撃装置から一方側端部に打撃力が入力された打撃力伝達軸は、静止状態における初期位置から打撃力伝達軸の長手方向に沿って他方側に移動して、他方側端部から被打撃部に打撃力を伝達する。反力受部材は、打撃力伝達軸が移動してもその位置が変化しないので、打撃力伝達軸が移動を開始した当初から、付勢部材の反力を速やかに受ける。反力受部材が速やかに付勢部材の反力を受けるので、付勢部材は、打撃力伝達軸に対して静止状態における初期位置に戻るように速やかに付勢して打撃力伝達軸の移動や振動を抑制することで、打撃力伝達軸を速やかに上記初期位置に戻して静止させることができる。   The striking force transmission shaft in which the striking force is input from the striking device to the one side end moves from the initial position in the stationary state to the other side along the longitudinal direction of the striking force transmission shaft, and hits from the other end. The striking force is transmitted to the part. Since the position of the reaction force receiving member does not change even if the striking force transmission shaft moves, the reaction force receiving member quickly receives the reaction force of the biasing member from the beginning of the movement of the striking force transmission shaft. Since the reaction force receiving member quickly receives the reaction force of the urging member, the urging member quickly urges the striking force transmission shaft to return to the initial position in the stationary state and moves the striking force transmission shaft. By suppressing the vibration, the striking force transmission shaft can be quickly returned to the initial position to be stationary.

上記の構成によれば、繰り返し行われる打撃力伝達軸による打撃力の伝達の際における、打撃力伝達軸の位置を上記初期位置に揃えることで、打撃装置から打撃力伝達軸に伝達される打撃力および打撃力伝達軸から被打撃部に伝達される打撃力のばらつきを抑制することができ、ひいては被打撃部に伝達される打撃力を安定させることができる。   According to the above configuration, the impact transmitted from the impact device to the impact force transmission shaft by aligning the position of the impact force transmission shaft with the initial position when the impact force is transmitted by the impact force transmission shaft that is repeatedly performed. Variations in the striking force transmitted from the force and striking force transmission shaft to the hit portion can be suppressed, and as a result, the striking force transmitted to the hit portion can be stabilized.

The other side small-diameter portion provided on the other side, and the reaction force receiving member includes a one-side reaction force receiving member provided on the one side in the longitudinal direction than the large-diameter portion and the large-diameter portion. And the other side reaction force receiving member provided on the other side in the longitudinal direction, and the biasing member includes a step surface of the large diameter portion and the one side small diameter portion in the longitudinal direction, and the one side The one side urging member disposed between the reaction force receiving member, the step surface of the large diameter portion and the other small diameter portion in the longitudinal direction, and the other side reaction force receiving member. And the other side biasing member.

上記（６）の構成によれば、一方側付勢部材および他方側付勢部材のうちの一方が、打撃力伝達軸が長手方向における一方側に移動した際に上記打撃力伝達軸が他方側に移動するように付勢し、一方側付勢部材および他方側付勢部材のうちの他方が、打撃力伝達軸が長手方向における他方側に移動した際に上記打撃力伝達軸が一方側に移動するように付勢する。つまり、一方側付勢部材と他方側付勢部材とで、打撃力伝達軸を付勢する方向を分担させることで、打撃力伝達軸が移動した際に移動方向に対応する付勢部材が速やかに上記打撃力伝達軸に対して付勢力を発揮することができる。このため、打撃力伝達軸を静止状態での初期位置に速やかに停止させることができる。   According to the configuration of (6) above, when one of the one side urging member and the other side urging member moves the striking force transmission shaft to one side in the longitudinal direction, the striking force transmission shaft is on the other side. When the other one of the one-side urging member and the other-side urging member moves the striking force transmission shaft to the other side in the longitudinal direction, the striking force transmission shaft is moved to one side. Energize to move. In other words, the one side biasing member and the other side biasing member share the direction in which the striking force transmission shaft is biased, so that when the striking force transmission shaft moves, the biasing member corresponding to the moving direction can be quickly In addition, it is possible to exert an urging force against the striking force transmission shaft. For this reason, the striking force transmission shaft can be quickly stopped at the initial position in the stationary state.

（７）幾つかの実施形態では、上記（６）に記載のハンマリング装置は、上記長手方向に沿って延在して上記大径部、上記一方側小径部、および上記他方側小径部を収納する筒状部材を備え、上記筒状部材の内周壁から突出する突出部が上記反力受部材となる。 (7) In some embodiments, the hammering device according to (6) extends along the longitudinal direction and includes the large diameter portion, the one side small diameter portion, and the other side small diameter portion. A protruding member that includes a cylindrical member to be housed and protrudes from an inner peripheral wall of the cylindrical member serves as the reaction force receiving member.

上記（７）の構成によれば、長手方向に沿って延在して大径部、一方側小径部および他方側小径部を収納する筒状部材により、打撃力伝達軸の長手方向に直交する方向への移動が制限されるので、繰り返し行われる打撃力の伝達の際における、打撃力伝達軸の長手方向に直交する方向における位置を揃えることができる。打撃力伝達軸の長手方向に直交する方向における位置を揃えることで、打撃装置から打撃力伝達軸に伝達される打撃力および打撃力伝達軸から被打撃部に伝達される打撃力を安定させることができる。   According to the configuration of (7) above, the cylindrical member that extends along the longitudinal direction and accommodates the large-diameter portion, the one-side small-diameter portion, and the other-side small-diameter portion is orthogonal to the longitudinal direction of the striking force transmission shaft. Since the movement in the direction is limited, it is possible to align the positions in the direction perpendicular to the longitudinal direction of the striking force transmission shaft when the striking force is transmitted repeatedly. By aligning the position of the impact force transmission shaft in the direction perpendicular to the longitudinal direction, the impact force transmitted from the impact device to the impact force transmission shaft and the impact force transmitted from the impact force transmission shaft to the hit portion are stabilized.

In this case, since the displacement of the urging member is suppressed, the urging member can stably exert the urging force, and as a result, the striking force transmission shaft can be accurately stopped at the initial position in the stationary state. Can be made.

（８）幾つかの実施形態では、上記（７）に記載のハンマリング装置は、上記打撃装置をさらに備え、上記打撃装置は、本体部と、上記静止状態では上記長手方向において上記一方側端部に対して離隔している打撃部であって、上記本体部に対して上記長手方向に沿って前後進可能に構成され、且つ、上記一方側端部に対して打撃力を伝達するように構成された打撃部と、を含み、上記筒状部材は、上記大径部、上記一方側小径部、および上記他方側小径部の一部を収納する第１筒状部材を含み、上記第１筒状部材は、上記長手方向における一方側開口端部から外周側に向かって延在する一方側フランジ部であって、上記打撃装置の上記本体部に固定された固定部材にフランジ締結により着脱可能に固定されるように構成された一方側フランジ部を含み、上記長手方向における上記第１筒状部材の上記一方側フランジ部と上記固定部材との間に挟持されるように構成された第１のスペーサの内周縁部が上記一方側反力受部材となる。 (8) In some embodiments, the hammering device according to (7) further includes the hitting device, and the hitting device has a main body portion and the one end in the longitudinal direction in the stationary state. A striking part spaced apart from the part, configured to be capable of moving back and forth along the longitudinal direction with respect to the main body part, and transmitting a striking force to the one side end part. The cylindrical member includes a first cylindrical member that houses a part of the large-diameter portion, the one-side small-diameter portion, and the other-side small-diameter portion; The cylindrical member is a one-side flange portion extending from the one-side opening end portion toward the outer peripheral side in the longitudinal direction, and can be attached to and detached from the fixing member fixed to the main body portion of the striking device by flange fastening. One side franc configured to be fixed to And the inner peripheral edge of the first spacer configured to be sandwiched between the one flange portion of the first cylindrical member and the fixing member in the longitudinal direction is the one side reaction force It becomes a receiving member.

上記（８）の構成によれば、打撃装置の本体部に固定された固定部材と第１筒状部材の一方側フランジ部との間に挟持されるように構成された第１のスペーサは、上記固定部材と第１筒状部材の一方側フランジ部とがフランジ締結により着脱可能に固定されているので、厚さの異なるものに交換可能である。打撃装置の打撃部と打撃力伝達軸の一方側端部とが繰り返し衝突すると、打撃部や一方側端部が摩耗して打撃部と一方側端部との間の間隔が広がり、打撃部から一方側端部への打撃力の伝達性能が低下する虞がある。これに対して、第１のスペーサを厚さの薄いものに交換して打撃部と一方側端部との間隔が広がるのを防止することで、打撃部から一方側端部への打撃力の伝達性能が低下することを長期間にわたり防止することができる。   According to the configuration of (8) above, the first spacer configured to be sandwiched between the fixing member fixed to the main body portion of the striking device and the one side flange portion of the first tubular member, Since the fixing member and the one-side flange portion of the first cylindrical member are detachably fixed by flange fastening, they can be exchanged with ones having different thicknesses.
