【考案の詳細な説明】
本考案は、器体内で圧縮ガスにより送給される金属、耐
火物、プラスチック等の粉末を燃焼火炎で溶融しながら
物体表面に吹付けるノズルミックス式粉末容射器に関す
るものである。[Detailed description of the invention] The present invention relates to a nozzle mix type powder injector that sprays powder of metals, refractories, plastics, etc., fed by compressed gas inside the container, onto the surface of an object while melting it with a combustion flame. It is something.
従来から使用されている粉末溶射器は、第１図に示すよ
うに器体中央のノズル１から噴射された粉末をノズル前
の器体内で酸素ガス２と液体燃料３を混合して燃焼する
火炎で溶融し吹付けるプレミックス構造の比較的簡単な
ものである。As shown in Fig. 1, a conventional powder sprayer uses a flame that mixes powder injected from a nozzle 1 in the center of the vessel with oxygen gas 2 and liquid fuel 3 in the vessel in front of the nozzle and burns the mixture. It has a relatively simple premix structure that is melted and sprayed.
しかしながらプレミックス型の溶射器は、面融点溶射材
料を使用した場合、未溶融部分の吹付堆積層を形成して
接着性を弱め、かつ、フレームの安定性を欠き、逆火の
危険もあるなど使用上の問題があった。However, when using a premix type thermal sprayer, when a surface melting point thermal spray material is used, a spray deposit layer is formed in the unmelted portion, weakening adhesion, and the flame is unstable, leading to the risk of backfire. There was a problem with using it.
本考案は、このような問題の観点から溶射材料の性質に
関係なく完全溶融をはかり、接着性の秀れた溶射吹付層

方に位置する如く装着したノズルミックス式粉末溶射器
である。In view of these problems, the present invention aims to create a thermal sprayer that completely melts the sprayed material regardless of its properties and forms a thermally sprayed layer with excellent adhesive properties. A nozzle mix type in which a powder sprayer with a powder spray nozzle arranged around it and oxygen spray nozzles arranged around it is installed in a large diameter nozzle pipe so that the end surface of the powder spray part is located inward from the tip surface of the large diameter nozzle. It is a powder sprayer.
以下本考案について図面を参照しながら詳細に説明する
。The present invention will be described in detail below with reference to the drawings.
第２図は本考案の一例をしめす。FIG. 2 shows an example of the present invention.
４は重油、灯油、タール等の液体燃料噴射ノズルで器体
の中央に設けられている。4 is a liquid fuel injection nozzle for heavy oil, kerosene, tar, etc., and is installed in the center of the vessel.
５は金属、耐火物等の粉末溶射ノズルで、液体燃料噴射
ノズルの周囲に設けられる。Reference numeral 5 denotes a powder spray nozzle made of metal, refractory, etc., and is provided around the liquid fuel injection nozzle.
６は酸素ガス噴射ノズルで粉末溶射ノズル５の周囲に設
けられ、７は大径ノズルパイプで前記各ノズルが内設さ
れその際、各ノズル端面が大径ノズルパイプ先端面より
内方に位置する如く設けられてい。Reference numeral 6 denotes an oxygen gas injection nozzle, which is provided around the powder spray nozzle 5, and 7, a large-diameter nozzle pipe in which each of the nozzles is installed, with the end surface of each nozzle located inward from the tip surface of the large-diameter nozzle pipe. It is set up as follows.
８は冷媒流通路で大径ノズルパイプ７の高温域に設けら
れる。8 is a refrigerant flow path provided in a high temperature region of the large diameter nozzle pipe 7.
各ノズルの形状は円形やスリット形状でもよく特に限定
するものでない。The shape of each nozzle may be circular or slit-shaped, and is not particularly limited.

着性の優れた溶射吹付層を形成する。In the present invention as described above, the injected material ejected from the powder injection nozzle 5 is dissolved while being diffused by the liquid fuel and oxygen gas ejected from the inner and outer layers, and the large diameter nozzle pipe 7 further lengthens and stabilizes the flame flame. It maintains the contact time with the powder during the melting process, promotes complete melting of the powder, and forms a thermally sprayed layer with excellent adhesion.
また作業面においても大径ノズルパイプ７によって逆火
、と騒音が防止される。Also, on the work surface, the large diameter nozzle pipe 7 prevents backfire and noise.
