詰まりの発生を防止することがでさるものである。[Le 21 is located.] This nailing nozzle 6 is installed by penetrating the side plate 2 as shown in FIG. It is preferable to set the upper central angle α around the rotating shaft 4 within a range of 90°, and also set the distance between the rotating shaft 4 and the nailer 7 nozzle 6 to If the distance from the inner circumference of drum 1 is b, then a:b= 1:(1~2)
It is best to set the position of the liquid striking nozzle 6 so that
In this way, the mounting position of the liquid striking nozzle 6 is preferably set at a position close to the rotating shaft 4, where the mixed material in the mixing tank 3 is difficult to come into contact with. Therefore, when the additive liquid 7 is supplied under pressure through the liquid inlet 19 and air is supplied under pressure through the gas inlet 18, when the air passes through the air nozzle 20, the liquid nozzle 2
The additive liquid 71 can be sucked from inside the air nozzle 20 by the Pentieri effect, and the additive liquid 7 can be blown out in the form of a mist through the air nozzle 20 along with air. In this way, the additive liquid 7 can be sprayed from the liquid injection nozzle 6 into the mixing tank 3 and added to the mixed material, but since the additive liquid 7 is blown out together with air, it becomes fine droplets of 100μ or less. Even if the mixed material is powder, the additive liquid 7 will be blown out evenly.
can be added. Since the corrugated nails 7 and the nozzle 6 are provided on the side plate 2 of the mixing tank 3, even if the mixed material is pressed against the cylindrical drum 1 by the centrifugal force of the shovel 5 that is rotationally driven by the rotating shaft 4, the mixing Corrugated nail nozzle 6 whose material is side plate 2
There is no risk that the nailing nozzle 6 will become clogged with the mixed material. Furthermore, by blowing out the additive liquid 7 from the nozzle 6 of the corrugated nail 7 and continuing to blow out air even after the mixing is finished, it is possible to prevent the additive liquid 7 from remaining in the nail driving nozzle 6, The additive liquid 7 remaining in the nail nozzle 6 may drip from the tip of the submerged nozzle 6, adhere to the mixing tank 3, and be added to the next mixed material, or the additive liquid 7 may solidify within the nail driving nozzle 6. This is to prevent the nail driving nozzle 6 from becoming clogged. At this time, the inner cylinder 17 is used as the corrugated nail nozzle 6.
By using a shaft valve equipped with a shaft valve, the effect of preventing surfing can be further enhanced. Effects of the Invention As described above, in the present invention, the corrugated nail nozzle is attached to the side plate of the mixing tank, and the nailing nozzle is formed as a two-fluid nozzle that spouts additive liquid together with gas. Even if the mixed material acts on the cylindrical drum of the mixing tank due to the centrifugal force of In the nailing/X-hole formed with a two-fluid nozzle, it is possible to continue releasing gas even after spouting the additive liquid, and after spouting the additive liquid, the additive liquid is This prevents the occurrence of clogging due to surfing or solidification of liquid.
