内塞を生ずる恐れが大であつた。 In the dry spraying of monolithic refractories, dust is generated as a problem in the working environment. Countermeasures include pre-moist treatment of sprayed materials and two-stage hydrogenation, but they do not completely prevent dust generation. Further, the generation of dust can be suppressed by increasing the distance from the water addition position to the nozzle spout, but this measure causes the material to adhere to the inside of the nozzle and the fine powder to sag at the nozzle tip. In particular, in the case of an elbow-shaped bent nozzle, there is a great possibility that the bent portion acts as resistance and the nozzle is clogged with material.
従つて本考案の目的は、水と耐火物等の微粉材
料の混合促進、微粉等のダレ現象とノズル閉塞の

するようにしたものである。 Hereinafter, it will be explained based on the drawings that the nozzle for spraying fine powder material such as monolithic refractories according to the present invention has a spiral rotor 2 that rotates along the inner surface of the nozzle 1.
The rotor 2 is forcibly driven by a motor 3 or the like.

介して水供給ホース１０に接続されている。 In the embodiment shown in FIG. 1, the tubular nozzle 1 is of an elbow type, and a motor 3 composed of an electric motor, a hydraulic motor, an air motor, etc. is installed on the outside of the bent part of the elbow type nozzle. has been done. The rotor 2, which has a linear cross section and is made of a steel spring covered with wear-resistant rubber, has one end connected to the output shaft of the motor 3, and the other end of the rotor 2 connected to the tip spout 4 of the straight pipe portion 1a. has reached. A bearing disk 6 of the rotor 2 is fitted to the end of the lining liner 5 of the nozzle 1 on the motor 3 side to prevent the sprayed material from moving toward the motor 3 side. A water ring type water injection part 8 is provided in the straight pipe portion 1b on the side of the material supply hose 7, and this is connected to the water supply hose 10 via a valve 9.

る。 The spraying material transferred from the material supply hose 7 into the nozzle 1 is mixed with water added from the water injection port 11 of the water injection section 8, but in the present invention, the material is inserted into the nozzle as described above. Since the spiral rotor 2 is forcibly driven by a motor or the like, the mixing state of water and material is improved, and the material to be sprayed is sprayed from the spout 4 onto the surface to be sprayed without separating from the water.
即ち、回転子２の螺旋回転作用によつて材料と
水の混合が良好に促進されるため、ノズル先端で

付着率の向上を図れるのである。 In other words, the spiral rotation of the rotor 2 promotes good mixing of the material and water, so there is no sagging of the fine powder material at the nozzle tip, reducing dust generation and improving the adhesion rate. .

層増強される。 Further, in the nozzle of the present invention, since the rotor 2 rotates along the inner surface of the nozzle, the adhesion of material to the inner wall of the nozzle is accurately prevented, and the material is discharged by the spiral rotation of the rotor 2. Since force is applied, nozzle clogging can be accurately prevented even in elbow type nozzles. The force for pushing and discharging this material is further enhanced when the rotor 2 is configured to have a plate-like cross section.

被吹付付着面の平滑度がよくなる。 In the embodiment shown in FIG. 2, the tip portion 2a of the rotor is made to protrude forward of the nozzle outlet 4, and its diameter is larger than that of the inner portion of the nozzle, so that the sprayed material is dispersed widely and uniformly. It is sprayed like this,
Improves the smoothness of the sprayed surface.

ことになる。 In the embodiment shown in FIG. 3, the rotor 2 has a straight part 2b parallel to the nozzle axis, and this straight part 2b rubs against the inner surface of the nozzle, so that material does not adhere to the inside of the nozzle. It will be more accurately blocked.
