Description

バーナー用触媒金具、操作方法、および熱風溶接機Catalyst fitting for burner, operation method, and hot air welding machine
　本発明はバーナー用触媒金具、操作方法、および熱風溶接機に関する。 The present invention relates to a catalyst fitting for a burner, an operation method, and a hot air welder.
　ガスの熱源を利用して、温風や熱風を発生させる装置が知られている。例えば、知られている装置においては、ガスノズルから噴出したガスは、高速ガス流の噴出効果によって吸気口から空気を吸引する。こうして、混合部で燃料ガスは空気と混合された混合ガスとなって、燃焼室に供給される。燃焼室の内部には触媒体が設けられており、混合ガスは触媒体の内部を通過するものである。このときに触媒体の触媒作用によって触媒燃焼し、燃焼熱を発生するようになっている。燃焼室の混合ガス入口と反対側には、点火装置が設けられている。 Devices that generate hot air or hot air using a gas heat source are known. For example, in a known apparatus, the gas ejected from the gas nozzle sucks air from the intake port due to the ejection effect of the high-speed gas flow. Thus, the fuel gas is mixed with air in the mixing section and supplied to the combustion chamber. A catalyst body is provided inside the combustion chamber, and the mixed gas passes through the inside of the catalyst body. At this time, catalytic combustion is generated by the catalytic action of the catalyst body, and combustion heat is generated. An ignition device is provided on the opposite side of the combustion chamber from the mixed gas inlet.
　使用者は、始動時には混合ガスに点火する。点火された混合ガスによって、触媒体の下流には小さな火炎が形成される。この火炎によって触媒体は加熱され、触媒体の温度が上昇する。こうして触媒体が活性温度に達すると、触媒体の表面で触媒燃焼が開始される。触媒燃焼が開始されると、火炎が触媒燃焼で吸収されて火炎は消滅する。この状態で、燃焼室に供給している混合ガスは、触媒体の全体で触媒燃焼を行ない、燃焼ガスは排気口から排出される。 The user ignites the mixed gas at start-up. A small flame is formed downstream of the catalyst body by the ignited mixed gas. The catalyst body is heated by this flame, and the temperature of the catalyst body rises. When the catalyst body reaches the activation temperature in this way, catalytic combustion is started on the surface of the catalyst body. When catalytic combustion is started, the flame is absorbed by catalytic combustion and the flame disappears. In this state, the mixed gas supplied to the combustion chamber performs catalytic combustion over the entire catalyst body, and the combustion gas is discharged from the exhaust port.

　小型で携帯できるサイズのバーナーを用いて強い熱風を作成する場合を考える。この場合、火力の強いバーナーを用いて限られたスペースに触媒体を置いて熱風を作成することになる。触媒体を加熱する際には多量の空気をスペースに取り入れないと火が消えてしまう。しかし、多量の空気をスペースに取り入れ続けると、今度は触媒体に触媒作用を発揮させた後に炎を消すことが困難である。
　１つの側面では、本発明は、小型で携帯できるサイズのバーナーを用いて多量の熱風を作成することを目的とする。 Consider the case of creating strong hot air using a small and portable burner. In this case, hot air is created by placing the catalyst body in a limited space using a burner with strong thermal power. When the catalyst body is heated, the fire goes out unless a large amount of air is taken into the space. However, if a large amount of air continues to be taken into the space, it is difficult to extinguish the flame after the catalyst body exhibits a catalytic action.
In one aspect, the present invention is directed to creating a large amount of hot air using a small and portable burner.
　上記目的を達成するために、開示のバーナー用触媒金具が提供される。このバーナー用触媒金具は、筒状をなし一端側がバーナーの炎の噴出部位に装着され、内部に触媒作用を発揮する部材が配置され側部に開口部が形成された筐体と、バーナーの炎の噴出前に開口部を開いておき、噴出後に開口部の開口面積を小さくする調節部と、を有している。 In order to achieve the above object, the disclosed catalyst fitting for a burner is provided. This burner catalyst fitting has a cylindrical shape, one end of which is attached to a burner flame injection site, a member that exhibits catalytic action is disposed inside, and an opening is formed on the side, and a burner flame And an adjustment section that opens the opening before the ejection of the gas and then reduces the opening area of the opening after the ejection.
　１態様では、小型で携帯できるサイズのバーナーを用いて多量の熱風を作成することができる。
　本発明の上記および他の目的、特徴および利点は本発明の例として好ましい実施の形態を表す添付の図面と関連した以下の説明により明らかになるであろう。 In one embodiment, a large amount of hot air can be created using a burner that is small and portable.

Examples of the gas cylinder 100 include a cassette cylinder for a stove that is filled with liquefied petroleum gas such as propane and butane.
　バーナー本体２は、ガスボンベ１００の液化ガスを燃料にして炎を噴出する。このバーナー本体２は、ガスボンベ１００を装着する装着部２１と、ガスボンベ１００に充填されている液体ガスを気化したガスを火口管２２に導くガス流路（図示せず）とを有している。また、バーナー本体２は、火口管２２において空気と混合された混合ガスに点火する点火部（図示せず）を有している。
　また、バーナー本体２には、ガス流路を流れるガスの流量を調節する調節ネジ２３が設けられている。
　火口管２２の先端側にはバーナー用接触金具３が、火口管２２に対して着脱自在に取り付けられている。
　バーナー用接触器具３は、筐体３１と、調節部３２とを有している。 The burner body 2 ejects flame using the liquefied gas in the gas cylinder 100 as fuel. The burner body 2 includes a mounting portion 21 for mounting the gas cylinder 100 and a gas flow path (not shown) for guiding the gas obtained by vaporizing the liquid gas filled in the gas cylinder 100 to the crater tube 22. Further, the burner body 2 has an ignition part (not shown) that ignites the mixed gas mixed with air in the crater tube 22.
The burner body 2 is provided with an adjusting screw 23 for adjusting the flow rate of the gas flowing through the gas flow path.
A burner contact fitting 3 is detachably attached to the tip of the crater tube 22 with respect to the crater tube 22.
The burner contact tool 3 includes a housing 31 and an adjustment unit 32.
　筐体３１は、筒状をなしている。この筐体３１の側部には、空気を筐体３１内部に取り入れる開口部３１１が形成されている。なお、開口部の形状や、数は図示のものに限定されない。
　調節部３２は、開口部３１１の開口面積を調節する際に用いる。
　バーナー用接触器具３の先端側にはＶ字型のノズル４がバーナー用接触器具３に対して着脱自在に取り付けられている。 The casing 31 has a cylindrical shape. An opening 311 for taking air into the housing 31 is formed on the side of the housing 31. Note that the shape and number of the openings are not limited to those illustrated.
The adjusting unit 32 is used when adjusting the opening area of the opening 311.
A V-shaped nozzle 4 is detachably attached to the tip of the burner contact device 3 with respect to the burner contact device 3.
　ノズル４には、溶接棒（図示せず）を通す筒４１が設けられている。なお、本実施の形態では、長尺シート等のつなぎ目の溶接を行う場合に適するノズル４を図示している。しかし、熱風の利用用途に応じてノズル４は、任意の形状のものに付け替えることができる。 The nozzle 4 is provided with a cylinder 41 through which a welding rod (not shown) is passed. In the present embodiment, a nozzle 4 suitable for welding a joint such as a long sheet is illustrated. However, the nozzle 4 can be replaced with an arbitrary shape according to the application of hot air.
　熱風溶接機１では、火口管２２から噴出した炎により、バーナー用接続器具３において触媒作用（触媒燃焼）を起こして熱風に変える。この熱風を用いて溶接棒を溶かし、長尺シート等のつなぎ目を溶接する。
　図２は、筐体を説明する図である。図２は、筐体３１を基端側から見た図である。 In the hot air welding machine 1, the flame ejected from the crater tube 22 causes a catalytic action (catalytic combustion) in the burner connection tool 3 to change to hot air. The hot rod is used to melt the welding rod and weld joints such as long sheets.
FIG. 2 is a diagram illustrating the housing. FIG. 2 is a view of the housing 31 as seen from the base end side.
　筐体３１内には、網目形状のセラミック３１２が配置されている。セラミック３１２は、触媒作用（触媒燃焼）を起こすときに用いられる。このセラミック３１２には触媒作用を起こす粉末が付着している。以下の説明では、粉末が付着したセラミック３１２を「触媒体」と言う。
　図３は、調節部を説明する図である。 A mesh-shaped ceramic 312 is disposed in the housing 31. The ceramic 312 is used when a catalytic action (catalytic combustion) occurs. The ceramic 312 has a powder that causes a catalytic action. In the following description, the ceramic 312 to which the powder is attached is referred to as “catalyst body”.
FIG. 3 is a diagram illustrating the adjusting unit.
　調節部３２は、筐体３１よりも半径が一回り大きな筒状の筒部３２１を有している。筒部３２１は、筐体３１の長手方向（図３中上下方向）に相対的な位置の移動が可能である。
　また、調節部３２は、把持部３２２を有している。利用者は、筐体３１に対して筒部３２１の位置を移動させる際に把持部３２２を使用する。
　筐体３１の側部には、突起３１３が設けられており、筒部３２１の側部には、突起３１３に対応する溝部３２１ａが形成されている。
　溝部３２１ａは、係合部３２１ａ１と、係合部３２１ａ２とを有している。 The adjustment part 32 has a cylindrical cylindrical part 321 whose radius is slightly larger than that of the casing 31. The cylindrical portion 321 can move relative to the longitudinal direction of the casing 31 (vertical direction in FIG. 3).
In addition, the adjustment unit 32 has a grip portion 322. The user uses the grip portion 322 when moving the position of the cylinder portion 321 with respect to the housing 31.
A protrusion 313 is provided on the side of the housing 31, and a groove 321 a corresponding to the protrusion 313 is formed on the side of the cylindrical part 321.
The groove part 321a has an engaging part 321a1 and an engaging part 321a2.
　係合部３２１ａ１は、筒部３２１が開口部３１１を覆わず、開口部３１１が全て開口した位置（図３に示す位置、以下「第１の位置」という）において突起３１３と係合することにより、筒部３２１を第１の位置に保持する。 The engaging portion 321a1 is engaged with the protrusion 313 at a position where the cylindrical portion 321 does not cover the opening 311 and the opening 311 is entirely open (the position shown in FIG. 3, hereinafter referred to as “first position”). The cylinder portion 321 is held at the first position.
　係合部３２１ａ２は、筒部３２１が開口部３１１を全て覆う位置（以下「第２の位置」という）において突起３１３と係合することにより、筒部３２１を第２の位置に保持する係合部３２１ａ２とを有する。 The engaging portion 321a2 engages with the protrusion 313 at a position where the cylindrical portion 321 covers the entire opening 311 (hereinafter referred to as “second position”), thereby holding the cylindrical portion 321 at the second position. Part 321a2.
　第１の位置において、開口部３１１から筐体３１内部に触媒体が触媒作用を発揮する際に十分な空気を取り入れることができる。なお、第１の位置において筒部３２１が開口部３１１を一部覆っていてもよい。筒部３２１が開口部３１１を覆う面積は、筒部３２１内に取り入れる空気の量によって適宜選択することができる。 In the first position, sufficient air can be taken into the casing 31 from the opening 311 when the catalytic body exerts a catalytic action. Note that the cylindrical portion 321 may partially cover the opening 311 at the first position. The area where the cylindrical part 321 covers the opening 311 can be appropriately selected depending on the amount of air taken into the cylindrical part 321.
　筒部３２１を第１の位置から第２の位置に移動させる際には、利用者は把持部３２２を把持して時計回り（図３では紙面奥側から紙面手前側に）に回転させる。これにより、突起３１３と係合部３２１ａ１との係合状態が解除される。そして、利用者は図３の上方向に把持部３２２を移動させる。これにより、開口部３１１の開口面積が少しずつ小さくなる。
　その後、突起３１３が溝部３２１ａに当接する時点では、開口部３１１の全てが筒部３２１により覆われている。
　利用者は把持部３２２を反時計回りに回転させる。これにより、突起３１３が係合部３２１ａ２に係合する。 When moving the cylinder part 321 from the first position to the second position, the user holds the grip part 322 and rotates it clockwise (in FIG. 3, from the back side to the front side). Thereby, the engagement state of the protrusion 313 and the engaging portion 321a1 is released. Then, the user moves the grip portion 322 upward in FIG. Thereby, the opening area of the opening part 311 becomes small little by little.
Thereafter, when the protrusion 313 contacts the groove 321a, the entire opening 311 is covered with the cylindrical portion 321.
The user rotates the grip 322 counterclockwise. Thereby, the protrusion 313 engages with the engaging portion 321a2.

　利用者は、把持部３２２を把持して筒部３２１を第１の位置に保持する。その後、利用者は、調節ネジ２３を用いて火口管２２にガスを排出させる。その後、利用者は点火部を操作して混合ガスに点火する。点火されたガスによって勢いの強い火炎が発生し、触媒体が加熱され、触媒体の温度が上昇する。その後、利用者は、把持部３２２を把持して筒部３２１を第２の位置に保持する。これにより、筒部３２１内部に供給される空気の量が低減する。このため火炎は見た目消滅するが、本体２と火口管２２の間から筒部３２１には一定量の空気は供給されるため、触媒体が活性温度に達し、触媒体の表面で触媒燃焼が開始される。このとき、触媒体自体は青白い炎で燃焼し続ける。ノズル４の先端部からは熱風が排出され、利用者はこの熱風を利用して溶接棒を用いて長尺シート等のつなぎ目の溶接を行う。 The user grips the grip portion 322 and holds the tube portion 321 in the first position. Thereafter, the user causes the crater tube 22 to discharge gas using the adjusting screw 23. Thereafter, the user operates the ignition unit to ignite the mixed gas. A strong flame is generated by the ignited gas, the catalyst body is heated, and the temperature of the catalyst body rises. Thereafter, the user grips the grip portion 322 and holds the tube portion 321 in the second position. Thereby, the quantity of the air supplied into the cylinder part 321 reduces. For this reason, the flame disappears visually, but since a certain amount of air is supplied from the space between the main body 2 and the crater tube 22 to the cylindrical portion 321, the catalyst body reaches the activation temperature, and catalytic combustion starts on the surface of the catalyst body. Is done. At this time, the catalyst body itself continues to burn with a pale flame. Hot air is discharged from the tip of the nozzle 4, and the user uses this hot air to weld a joint such as a long sheet using a welding rod.
　以上述べたように、熱風溶接機１によれば、点火の際に取り入れる空気の量を調整できる。具体的には、点火時には、開口部３１１から多量の空気を取り入れ、その後開口部３１１を覆うようにした。これにより、小型で携帯できるサイズのバーナーを用いて火力の強い炎を起こした場合においても筐体３１内のスペース内で触媒作用を起こし、強い熱風を作成することができる。
　＜第１変形例＞ As described above, according to the hot air welder 1, the amount of air taken in at the time of ignition can be adjusted. Specifically, at the time of ignition, a large amount of air was taken from the opening 311 and then the opening 311 was covered. Thereby, even when a flame with a strong heating power is generated by using a small and portable burner, a catalytic action is generated in the space in the casing 31 and a strong hot air can be created.
<First Modification>
　図６および図７は、変形例のバーナー用触媒金具を説明する図である。図１と同じ機能を持つ部分には同じ符号を付している。なお、図６ではノズル４の表記を省略している。 FIG. 6 and FIG. 7 are diagrams for explaining a modified catalytic metal fitting for a burner. Parts having the same functions as those in FIG. 1 are denoted by the same reference numerals. In FIG. 6, the description of the nozzle 4 is omitted.
　変形例のバーナー用接触器具３ａは、調節部３２ａの形状が図１に示すバーナー用接触器具１とは異なっている。具体的には、調節部３２ａは、把持部３２２が筒部３２１に対して着脱可能になっている。筒部３２１には、突起３２３、３２４が設けられている。また、変形例の把持部３２２には、突起３２３、３２４に対応する孔部（図示せず）が設けられている。これにより、利用者が右利きであっても左利きであっても、使いやすい方に把持部３２２をセットすることができる。また、把持部３２２を取り外すことで作業の妨げにならない。さらに、熱風により把持部３２２が加熱され、誤って利用者に触れてしまうことを抑制することができる。
　さらに、調節部３２ａにおいては、把持部３２２とは異なる形状の把持部を筒部３２１に取り付けることもできる。
　図８は、異なる形状の把持部を取り付けたときのバーナー用触媒金具を説明する図である。なお、図８ではノズル４の表記を省略している。 The burner contact device 3a according to the modification is different from the burner contact device 1 shown in FIG. 1 in the shape of the adjusting portion 32a. Specifically, the adjustment portion 32 a is configured such that the grip portion 322 is detachable from the cylinder portion 321. The cylindrical portion 321 is provided with protrusions 323 and 324. In addition, the grip portion 322 of the modified example is provided with holes (not shown) corresponding to the protrusions 323 and 324. Thereby, regardless of whether the user is right-handed or left-handed, the grip portion 322 can be set in an easy-to-use manner. In addition, the removal of the grip portion 322 does not hinder the work. Furthermore, it can suppress that the holding | grip part 322 is heated with a hot air and touches a user accidentally.
Furthermore, in the adjustment part 32 a, a grip part having a shape different from that of the grip part 322 can be attached to the cylinder part 321.
FIG. 8 is a view for explaining a catalyst fitting for a burner when gripping portions having different shapes are attached. In FIG. 8, the description of the nozzle 4 is omitted.
　把持部３２２ａは、突起３２３、３２４に係合する係合部３２２ａ１を有している。係合部３２２ａ１には、係合部３２２ａ１を突起３２３、３２４から着脱できる遊びが設けられている。係合部３２２ａ１を突起３２３、３２４に係合させる際には、利用者は把持部３２２ａの取っ手部分を把持してバーナー用接触器具３ａの先端側から把持部３２２ａを潜らせる。 The gripping part 322a has an engaging part 322a1 that engages with the protrusions 323 and 324. The engaging portion 322a1 is provided with a play that allows the engaging portion 322a1 to be detached from the protrusions 323 and 324. When engaging the engaging portion 322a1 with the protrusions 323 and 324, the user grips the handle portion of the gripping portion 322a and causes the gripping portion 322a to be hidden from the distal end side of the burner contact device 3a.
　図８に示す状態においては、利用者は把持部３２２ａの取っ手部分を把持して筒部３２１を時計回り、反時計回りに回転させることで突起３１３を係合部３２１ａ１に係合させたり、係合部３２１ａ２に係合させたりすることができる。
　図９は、ノズルが装着された変形例のバーナー用触媒金具を説明する図である。 In the state shown in FIG. 8, the user grips the handle portion of the grip portion 322a and rotates the tube portion 321 clockwise or counterclockwise to engage the protrusion 313 with the engagement portion 321a1, or It can be engaged with the joint portion 321a2.
FIG. 9 is a view for explaining a burner catalyst fitting of a modified example equipped with a nozzle.
　把持部３２２ａの環状部分の切り欠き部３２２ａ２（切り欠き部の他方の端部は調節部３２ａの裏に隠れてみえない）の長さは筒部３２１の断面の直径よりも大きく形成されている。このため、ノズル４が装着された状態であっても把持部３２２ａを筒部３２１から離脱させることができる。 The length of the notch 322a2 (the other end of the notch cannot be hidden behind the adjustment part 32a) of the annular part of the grip part 322a is formed larger than the diameter of the cross section of the cylinder part 321. . For this reason, the gripping part 322a can be detached from the cylindrical part 321 even when the nozzle 4 is mounted.
