Description

【0001】
【発明の属する技術分野】
本発明は、主として都市ごみ等の焼却炉に適用されて固定火格子と可動火格子とが被燃焼物の送り方向に交互に配設された階段式ストーカの改良に関する。
【0002】
【従来の技術】
従来、この種の階段式ストーカとしては、例えば特開平7−305826号、特開平9−60851号、特開平9−210327号に記載されたものが知られている。
当該階段式ストーカは、基本的に、被燃焼物の送り方向に固定火格子と可動火格子を交互に配設して成る階段式ストーカに於て、前記各火格子を支持する火床フレームと、火床フレームに設けられた火床フレーム掛合部と、各火格子に設けられて火床フレーム掛合部に横動可能に掛合される火格子掛合部とを具備している。
この様なものは、火床フレームに対して火格子が炉幅方向に動く事ができ、側壁部に熱膨張を吸収する熱膨張吸収機構を設けて置けば、火格子間に隙間を設ける必要がない。
【0003】
【発明が解決しようとする課題】
ところが、この様なものは、火格子を交換する場合、火床フレームの側方から火格子を横動して挿脱する様になっていたので、側壁部に設けられた熱膨張吸収機構を分解しないと交換する事ができなかった。
本発明は、叙上の問題に鑑み、これを解消すべく創案されたもので、その課題とする処は、側壁部に設けられた熱膨張吸収機構を分解する事なく、火格子を交換できる様にした階段式ストーカを提供するにある。
【0004】
【課題を解決するための手段】
本発明の階段式ストーカは、基本的に、被燃焼物の送り方向に固定火格子と可動火格子を交互に配設して成る階段式ストーカに於て、前記各火格子を支持する火床フレームと、火床フレームに設けられた火床フレーム掛合部と、各火格子に設けられて火床フレーム掛合部に横動可能に掛合される火格子掛合部と、火床フレーム掛合部の一部を火格子の幅に応じて分割する事に依り形成されて火床フレームに着脱可能に取付けられる分割掛合部とを具備した事に特徴が存する。
【0005】
組立時には、分割掛合部が火床フレームから外され、ここから順次火格子が挿入されて横動される事に依り火格子掛合部と火床フレーム掛合部とが掛合されて組立てが進められると共に、最後の火格子の火格子掛合部に分割掛合部が掛合されて火床フレームに取付けられる事に依り最後の火格子が火床フレームに取付けられる。
分解時には、前述の逆の要領で行なわれる。
火床フレームに対して火格子を上から横に移動させる事に依り組立・分解できるので、側壁部に設けられる熱膨張吸収機構を分解する事なく、火格子を交換する事ができる。
【0006】
分割掛合部は、火床フレーム掛合部の炉幅方向の中央部にした方が好ましい。この様にすれば、熱損傷が激しい中央部の火格子を短時間で交換する事ができる。
【0007】
【発明の実施の形態】
以下、本発明の実施の形態を、図面に基づいて説明する。
図1は、本発明の階段式ストーカを適用したごみ焼却炉の概要を示す縦断側面図。図2は、本発明の階段式ストーカを示す縦断側面図。図3は、図2の一部を拡大して示す縦断側面図。図4は、火床フレームを示す斜視図である。
【0008】
階段式ストーカ1は、固定火格子2、可動火格子3、火床フレーム4、火床フレーム掛合部5、火格子掛合部6、分割掛合部7とからその主要部が構成されて居り、ごみ焼却炉40に適用される。
【0009】
ごみ焼却炉40は、図1に示す如く、ごみ供給ホッパ41、ごみ供給装置42、乾燥ストーカ43、燃焼・後燃焼ストーカ44、助燃バーナ45、灰出しホッパ46、落下灰コンベア47、灰出し装置48等から構成されている。
乾燥ストーカ43と燃焼・後燃焼ストーカ44は、夫々階段式ストーカ1を為している。
【0010】
固定火格子2と可動火格子3は、火床(ストーカ)を形成して居り、ごみ等の被燃焼物の送り方向(前方向、図1,2に於て右方向)に交互に配設されて固定火格子2に対して可動火格子3が同方向に移動可能に構成されている。
各火格子2,3は、所定の前方仰角θ(例えば20°)だけ傾斜した状態で火床フレーム4に支持されていると共に、火格子体8とシュー9と空気吹出口10とを備えている。
火格子体8は、下方と後方が開放した箱状を呈し、内部にはフィン11が、前側内部にはノズル12と凹溝13を備えた仕切壁14が設けられている。
シュー9は、断面略凸状を呈し、火格子体8の凹溝13に昇降可能に嵌合される凸条15と、隣接する火格子体8の上面に摺動可能に当合する摺動面16とを備えている。
空気吹出口10は、火格子体8の前側下端とシュー9の前側上端との間に形成されている。
【0011】
火床フレーム4は、各火格子2,3を支持するもので、この例では、角パイプに依り作製されている。
固定火格子2用の火床フレーム4は、ストーカフレーム(図示せず)にその両側部が取付けられている。
可動火格子3用の火床フレーム4は、駆動フレーム17に取付けられている。駆動フレーム17は、ストーカフレームに横軸廻りに回転可能に設けられたローラ18に依り前後動可能に支持されていると共に、油圧シリンダ等の往復駆動装置19に依り前後方向に往復動される様にしてある。
【0012】
火床フレーム掛合部5は、火床フレーム4に設けられたもので、この例では、掛凸部にしてあり、平鋼に依り作製されて居り、火床フレーム4より稍短い平鋼が中央部と両側部に分割されると共に、中央部を除く両側部が火床フレーム4の上面にその前側(図2に於て右側)を前方に突出して溶接される事に依り形成されている。
【0013】
火格子掛合部6は、各火格子2,3に設けられて火床フレーム掛合部5に横動可能に掛合されるもので、この例では、掛凸部に適合する掛凹部にしてあり、各火格子2,3を為す火格子体8の後側下部に略倒立L型を呈する凹溝を削設する事に依り形成されている。
【0014】
火床フレーム掛合部5と火格子掛合部6は、火床フレーム4に対する各火格子2,3の左右方向(炉幅方向)の横動と若干の俯仰動を許容すると共に、それ以外の運動を阻止する様にしてある。
【0015】
分割掛合部7は、火床フレーム掛合部5の一部を火格子2,3の幅に応じて分割する事に依り形成されて火床フレーム4に着脱可能に取付けられるもので、この例では、火床フレーム掛合部5の炉幅方向の中央部にしてある。つまり、中央部の溶接されない平鋼が、火床フレーム掛合部5と一直線上に揃う様に、適数(二つ)のボルト20に依り火床フレーム4の上面に着脱可能に取付けられる。分割掛合部7の長さLは、火格子2,3を為す一つの火格子体8の横幅より若干大きくしてある。
【0016】
次に、この様な構成に基づいて作用を述解する。
階段式ストーカ1の組立時には、分割掛合部7が火床フレーム4から外され、ここから順次火格子2,3(つまり火格子2,3を為す火格子体8、以下同様)が挿入されて側方へ横動される事に依り火床フレーム掛合部5と火格子掛合部6とが掛合されて組立てが進められると共に、最後の火格子2,3の火格子掛合部6に分割掛合部7が掛合されてボルト20にて火床フレーム4に取付けられる事に依り最後の火格子2,3が火床フレーム4の中央部に取付けられる。組立は、順次下流側(図2の右側)から上流側に向かって行なわれる。
この様にすれば、火格子2,3の一つ一つをボルト締めする必要がないので、組立が簡便になると共に、炉幅方向に火格子2,3が拘束される事がないので、側壁部に熱膨張を吸収する為の熱膨張吸収機構(図示せず)を設けて置けば、火格子2,3の横方向の隣接間に隙間を設ける必要がない。
【0017】
次に、階段式ストーカ1の分解時には、分割掛合部7が火床フレーム4から外されて中央部の火格子2,3が上方へ抜き取られると共に、その他の火格子2,3が順次中央部へ寄せられて上方へ抜き取られる。分解は、順次上流側から下流側に向かって行なわれる。
【0018】
任意の火格子2,3を交換する場合には、交換を行なう火格子2,3がある段の分割掛合部7が外されると共に、直上の段の火格子2,3が仰動されてその先端が上方に浮かされ、後は分解時と同様に中央部の火格子2,3から抜き取られると共に、その他の火格子2,3が順次中央部へ寄せられて抜き取られ、目的の火格子2,3が取り外される。そして、その後の組立は、前述の逆の手順で行なわれて交換が完了する。
【0019】
この様に組立・分解時には、火格子2,3の下方から行なう作業は、中央部の分割掛合部7を外す事だけであり、それ以外は火格子2,3の上方(炉内側)から簡便に行なう事ができる。
火床フレーム4に対して火格子2,3を上から横に移動させる事に依り組立・分解が行なえるので、側壁部に設けられる熱膨張吸収機構を分解する事なく、火格子2,3を交換する事ができる。
火床フレーム掛合部5は、平鋼に依り形成しているので、特段の形状加工をする必要がなく、コストの低減を図る事ができる。
分割掛合部7は、火床フレーム掛合部5の炉幅方向の中央部にしてあるので、熱損傷が激しい中央部の火格子2,3を短時間で交換する事ができる。
火格子2,3は、火格子体8に対してシュー9が分離できるので,シュー9が摩耗した場合には、これのみを取り替える事ができる。この場合、火格子2,3は、火床フレーム掛合部5と火格子掛合部6に依り火床フレーム4に対して若干俯仰できる様にしてあるので、分割掛合部7を外す事なく、その先端を持ち上げてシュー9のみを取り替える事ができる。
【0020】
尚、火床フレーム4は、先の例では、角パイプで作製していたが、これに限らず、例えばH形材やレール材等で作製しても良い。
火床フレーム掛合部5と火格子掛合部6は、先の例では、火床フレーム掛合部5を掛凸部にすると共に、火格子掛合部6を掛凹部にしたが、これに限らず、例えばこれらを逆にしても良い。
火床フレーム掛合部5と火格子掛合部6は、先の例では、平鋼とこれに適合する略倒立L型の凹溝であったが、これに限らず、例えば特開平9−60851号や特開平9−60851号の様にアリとアリ溝等にしても良い。
分割掛合部7は、先の例では、一つの火格子体8の横幅に呼応させたものあったが、これに限らず、例えば複数の火格子体8の横幅に呼応させたものであっても良い。
【0021】
【発明の効果】
以上、既述した如く、本発明に依れば、次の様な優れた効果を奏する事ができる。
(1) 火格子、火床フレーム、火床フレーム掛合部、火格子掛合部、分割掛合部とで構成し、とりわけ火床フレーム掛合部の一部を火格子の幅に応じて分割する事に依り形成されて火床フレームに着脱可能に取付けられる分割掛合部を設けたので、側壁部に設けられた熱膨張吸収機構を分解する事なく、火格子を交換できる。

[0007]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a longitudinal side view showing an outline of a waste incinerator to which a stepped stoker according to the present invention is applied. FIG. 2 is a longitudinal side view showing a stepped stalker according to the present invention. FIG. 3 is a longitudinal side view showing a part of FIG. 2 in an enlarged manner. FIG. 4 is a perspective view showing a fire bed frame.
[0008]
The stair-type stoker 1 is composed of a fixed grate 2, a movable grate 3, a fire bed frame 4, a fire bed frame hooking part 5, a grate hooking part 6, and a divided hooking part 7, and the main part thereof is garbage. It is applied to the incinerator 40.
[0009]
As shown in FIG. 1, the waste incinerator 40 includes a waste supply hopper 41, a waste supply device 42, a dry stoker 43, a combustion / post-combustion stoker 44, an auxiliary burner 45, an ash removal hopper 46, a falling ash conveyor 47, and an ash removal device. It consists of 48 grades.
The dry stoker 43 and the combustion / post-combustion stoker 44 form a stepped stoker 1, respectively.
[0010]
The fixed grate 2 and the movable grate 3 form a fire bed (stalker), and are alternately arranged in the feed direction of the combustibles such as dust (forward direction, right direction in FIGS. 1 and 2). Thus, the movable grate 3 is configured to be movable in the same direction with respect to the fixed grate 2.
Each grate 2, 3 is supported by the fire bed frame 4 in a state inclined by a predetermined forward elevation angle θ (for example, 20 °), and includes a grate body 8, a shoe 9, and an air outlet 10. Yes.
The grate body 8 has a box shape that is open at the bottom and rear, and is provided with fins 11 inside and a partition wall 14 provided with nozzles 12 and grooves 13 inside the front side.
The shoe 9 has a substantially convex cross section, and a ridge 15 fitted to the groove 13 of the grate body 8 so as to be movable up and down, and a slide slidably engaged with the upper surface of the adjacent grate body 8. Surface 16.
The air outlet 10 is formed between the front lower end of the grate body 8 and the front upper end of the shoe 9.
[0011]
The fire bed frame 4 supports the grate 2 and 3, and in this example, is made of a square pipe.
The fire bed frame 4 for the fixed grate 2 is attached to both sides of a stoker frame (not shown).
The firebed frame 4 for the movable grate 3 is attached to the drive frame 17. The drive frame 17 is supported so as to be able to move back and forth by a roller 18 provided on the stoker frame so as to be rotatable about a horizontal axis, and is reciprocated in the front-rear direction by a reciprocating drive device 19 such as a hydraulic cylinder. It is.
[0012]
The firebed frame hooking portion 5 is provided on the firebed frame 4. In this example, the hooking frame hooking portion 5 is a hooking convex portion and is made of flat steel. The two sides excluding the central part are formed by being welded to the upper surface of the firebed frame 4 with its front side (right side in FIG. 2) protruding forward.
[0013]
The grate engagement portion 6 is provided in each of the grate 2 and 3 and is engaged with the firebed frame engagement portion 5 so as to be laterally movable. It is formed by cutting a concave groove having a substantially inverted L shape at the lower rear side of the grate body 8 that forms the grate 2 and 3.
[0014]
The firebed frame engaging part 5 and the grate engaging part 6 allow lateral movement of the fire grates 2 and 3 in the left-right direction (furnace width direction) and slight up-and-down movement with respect to the firebed frame 4 and other movements. It is trying to prevent.
[0015]
The division hooking portion 7 is formed by dividing a part of the firebed frame hooking portion 5 according to the width of the grate 2 and 3, and is detachably attached to the firebed frame 4. In this example, The center part in the furnace width direction of the firebed frame engaging part 5 is formed. That is, the flat steel that is not welded at the center is detachably attached to the upper surface of the firebed frame 4 by an appropriate number (two) of bolts 20 so as to be aligned with the firebed frame hooking portion 5. The length L of the split engagement portion 7 is slightly larger than the lateral width of one grate body 8 that forms the grate 2 and 3.
[0016]
Next, the operation will be described based on such a configuration.
At the time of assembling the staircase stoker 1, the divisional engagement portion 7 is removed from the firebed frame 4, and the grate 2 and 3 (that is, the grate body 8 forming the grate 2 and 3, and so on) are sequentially inserted from here. As it is laterally moved, the firebed frame hooking part 5 and the grate hooking part 6 are hooked up and the assembly is advanced, and the split hooking part is added to the grate hooking part 6 of the last grate 2 and 3. 7 and the last grate 2 and 3 are attached to the center part of the fire bed frame 4 by being attached to the fire bed frame 4 with bolts 20. The assembly is sequentially performed from the downstream side (the right side in FIG. 2) toward the upstream side.
In this way, since it is not necessary to bolt each of the grate 2 and 3, it is easy to assemble, and the grate 2 and 3 are not restrained in the furnace width direction. If a thermal expansion absorption mechanism (not shown) for absorbing thermal expansion is provided on the side wall portion, there is no need to provide a gap between the horizontal adjacent grids 2 and 3.
[0017]
Next, at the time of disassembling the staircase stoker 1, the division hooking portion 7 is removed from the fire bed frame 4, the central grate 2 and 3 is extracted upward, and the other grate 2 and 3 are sequentially placed in the central portion. And is pulled upward. The decomposition is sequentially performed from the upstream side toward the downstream side.
[0018]
When replacing any grate 2 or 3, the split engagement portion 7 at the stage where the grate 2 or 3 to be exchanged is removed and the grate 2 or 3 at the upper stage is lifted. The tip of the grate 2 is lifted upward, and thereafter, it is extracted from the grate 2 and 3 in the central part as in the case of disassembly, and the other grate 2 and 3 are sequentially drawn to the central part and extracted. , 3 are removed. Subsequent assembly is performed in the reverse procedure described above, and the replacement is completed.
[0019]
In this way, when assembling and disassembling, the work to be performed from below the grate 2 and 3 is only to remove the split portion 7 at the center, and the rest is simple from above the grate 2 and 3 (inside the furnace). Can be done.
Assembling / disassembling can be performed by moving the grate 2, 3 sideways from the top with respect to the firebed frame 4. Can be exchanged.
Since the firebed frame engaging portion 5 is formed of flat steel, it is not necessary to perform special shape processing, and the cost can be reduced.
Since the division engagement portion 7 is the central portion of the fire bed frame engagement portion 5 in the furnace width direction, it is possible to replace the grate 2 and 3 in the central portion where heat damage is severe in a short time.
Since the grate 2 and 3 can separate the shoe 9 from the grate body 8, when the shoe 9 is worn, only this can be replaced. In this case, the grate 2 and 3 can be lifted up slightly with respect to the firebed frame 4 by the firebed frame hooking portion 5 and the grate hooking portion 6, so that the split hooking portion 7 is not removed. Only the shoe 9 can be replaced by lifting the tip.
[0020]
In addition, although the firebed frame 4 was produced with the square pipe in the previous example, it is not restricted to this, For example, you may produce with an H-shaped material, a rail material, etc.
In the previous example, the firebed frame hooking part 5 and the grate hooking part 6 have the firebed frame hooking part 5 as a hanging convex part and the grate hooking part 6 as a hanging concave part. For example, these may be reversed.
In the previous example, the firebed frame engaging portion 5 and the grate engaging portion 6 were flat steel and a substantially inverted L-shaped groove adapted to the flat steel. However, the present invention is not limited thereto, and for example, Japanese Patent Laid-Open No. 9-60851. Alternatively, as in JP-A-9-60851, ants and dovetail grooves may be used.
In the previous example, the division engagement portion 7 was made to respond to the width of one grate body 8, but is not limited to this, for example, to be made to correspond to the width of a plurality of grate bodies 8. Also good.
[0021]
【The invention's effect】
As described above, according to the present invention, the following excellent effects can be obtained.
(1) It consists of a grate, a firebed frame, a firebed frame hooking part, a grate hooking part, and a split hooking part. Especially, a part of the firebed frame hooking part is divided according to the width of the grate. Therefore, since the split engagement portion formed so as to be detachably attached to the fire bed frame is provided, the grate can be replaced without disassembling the thermal expansion absorbing mechanism provided on the side wall portion.
