本発明は研掃材を吹きつけて被研掃材表面に付
着しているスケール等の除去を行う研掃装置に関

のメンテナンスが大変になると共に、運転コスト
が増大する等の問題を有していた。 When removing scale etc. adhering to the surface of the material to be polished by projecting an abrasive material onto the material to be polished, the abrasive material is mixed with pressurized fluid and then projected. It is difficult to mix the material into a jet stream and spray it uniformly onto the material to be polished due to the difference in specific gravity between the material and the fluid, and this mixed state immediately appears as uneven polishing on the surface of the material to be polished. In addition, when abrasive material is mixed with pressure fluid and sprayed as described above, the injection nozzle is worn out by the abrasive material in a short period of time, which requires maintenance such as replacement. This poses problems such as increased labor costs and increased operating costs.

め、均一な研掃を行えるようにしたものである。 The present invention has been made in view of these conventional problems, and includes a pressure fluid injection nozzle that allows a jet flow of pressure fluid to collide with the surface of a workpiece to be polished at a required angle of inclination. An abrasive material supply nozzle for supplying abrasive material from above is provided at an arbitrary position directly above the abrasive material, so that the abrasive material is placed on the inclined jet stream and collides with the surface of the material to be polished. This allows for good dispersion of the abrasive material and enables uniform cleaning.

The abrasive material nozzle side header 2b is separated, and the abrasive material nozzle side header 2b is moved to determine the supply position of the abrasive material 7 relative to the jet stream 6 (distance from the injection port 4' of the pressure fluid injection nozzle 4).

最適に選定することもできる。 In the above, a jet stream 6 is formed from the pressure fluid injection nozzle 4 toward the material to be polished 1, and the abrasive material 7 is dropped and supplied from the abrasive material supply nozzle 5. Then,
The abrasive material 7 is carried by the jet flow 6 of the pressurized fluid and collides with the surface of the material to be polished 1, thereby performing the abrasive cleaning. At this time, the abrasive material 7 is dropped and supplied to a position relatively close to the injection port 4' of the pressure fluid injection nozzle 4, so that it is dispersed by the jet flow 6 and the surface of the material 1 to be abraded is The surface of the material to be polished 1 can be uniformly polished. Further, at this time, by moving the abrasive material nozzle side header 2b, the supply position of the abrasive material 7 in the jet stream 6 can be changed, and the dispersion state of the abrasive material 7 can be changed and adjusted. Furthermore, by rotating the entire nozzle header 2 and changing the inclination angle α of the pressure fluid injection nozzle 4, it is also possible to optimally select the spray angle of the jet stream 6 onto the material to be polished 1.

は勿論である。 In the above, the jet flow 6 of the pressure fluid injected from the jet port 4' is wide in the left-right direction (width direction) in FIG. 1 and narrow in the left-right direction (front-back direction) in FIG. If the injection port of the pressure fluid injection nozzle 4 is formed to have a so-called flat injection pattern, the abrasive material 7 can be easily and reliably supplied onto the jet stream 6, and the dispersibility of the abrasive material 7 can be improved. You can improve your performance. Moreover, if the jet pattern of the jet flow 6 is made flat in this way,
Of course, it is possible to obtain a long cleaning/processing pattern in the width direction.
