たものである。2. Description of the Related Art As a powdery substance discharging device, there has been known a device for finely crushing rock wool for construction, for example, and discharging the crushed rock wool at high air pressure. The discharging device includes a charging unit for charging rock wool, a rock wool transferring means for transferring the rock wool in the charging unit, a crushing chamber for crushing the rock wool transferred by the rock wool transferring means, and a crushing chamber for this. And a discharge means for discharging the crushed rock wool inside the receiving chamber to the outside of the receiving chamber with high air pressure, and the receiving chamber is provided inside the receiving chamber. It is provided with a partitioning member that is partitioned into a plurality of parts, and a pressure feeding path that is disposed below the partitioning member and that pressure-feeds the powdery material by the pressure-feeding means. Then, each of the compartments partitioned by rotating the partition member composed of the central axis and the radial wall in the receiving chamber sequentially receives a predetermined amount of crushed rock wool from the crushing chamber, and presses down a predetermined amount by a predetermined amount. The crushed rock wool of the pressure feeding path is sent from the discharge port provided at the end side of the pressure feeding path by the high air pressure from the introduction port provided at the starting end side of the pressure feeding path. Then, the crushed rock wool discharged is sprayed on the wall surface of the building while being mixed with cement milk at a constant ratio to form the wall surface.

できない。However, in this case, when the ground rock wool that has received a predetermined amount from the crushing chamber into each partition chamber is sent to the pressure feeding path,
In particular, there is a problem that the ground rock wool adheres to the wall surface near the central axis and the crushed rock wool cannot be fed by a predetermined amount to the pressure feeding path. As a result, it becomes impossible to sequentially discharge a fixed amount of ground rock wool from the discharge port. In particular, as the rotation of the partition member is accelerated, the amount attached to the wall surface of the partition member increases due to centrifugal force or the like, and the influence thereof becomes remarkable. Therefore, in such a case, the discharge amount cannot be increased even if the partition member is rotated at a high speed.

When placed on the four rotary members 12 ... 12 inside, the four rotary members 12 ... 12 are crushed from below.
Then, the rock wool crushed to some extent is transferred by the two screw conveyors 3, 3 to the two crushing chambers 4, 4 connected to each other. At that time, since the screw conveyors 3 and 3 are installed so as to be higher than the height of the partition wall 11b of the tank tank 11, rock wool is used for one screw.
When there is a large amount on the conveyor 3 side, the surplus rock wool is sent to the other screw conveyor 3 side over the partition wall 11b. As a result, the screw conveyors 3 and 3 can always transfer an appropriate amount of rock wool to the crushing chambers 4 and 4, and
The two screw conveyors 3 and 3 can transfer approximately the same amount of rock wool. Then, in each of the crushing chambers 4, it is crushed by the crushing rotation member 41 into crushed rock wool to the extent that it can be sprayed.

2, 42 is dropped into each of the receiving chambers 5 and enters one of the partitioned chambers 100 partitioned by the partitioning blades 51b ... 51b of the material supply member 51. When the material supply member 51 reaches the pressure feeding path 90 after rotating about half a turn at a constant angular velocity, the compartment 1
The crushed rock wool in 00 is dropped onto the pressure feeding path 90. Further, at that time, the air of the blowers 80, 80 connected to the air introduction port 52 of the pressure feeding path 90 flows toward the discharge ports 6, 6 and a part of the air is applied to the air contact portion of the flow direction changing member 91. When it hits 92, it flows toward the inside of the upper compartment 100. As a result, the air is divided into blades 51b ... 51b.
The crushed rock wool that hits the wall surface of
It will not be dropped and left attached. Then, the crushed rock wool dropped onto the pressure feeding path 90 is discharged from each of the discharge ports 6 and 6 by the air flowing toward the discharge ports 6 and 6. At this time, the flow direction changing member 91
Is disposed in a floating state without coming into contact with the wall surface in the pressure feeding path 90, so that the crushed rock wool is not caught by the flow direction changing member 91 and stopped. As a result, each of the compartments 100 can reliably discharge the crushed rock wool received from the crushing chamber 4 without any residue. FIG. 10 is a graph showing the relationship between the number of revolutions of the material supply member 51 and the discharge amount from the discharge port 6 in the case of this embodiment and the case of the conventional example in which the flow direction changing member 91 is not provided. . In the figure, shows the present embodiment and shows the conventional example. In this measurement, the receiving chamber 5 having an inner diameter of 200 mm was used and the discharge pressure was 0.5 kg / m 2 .

It is getting bigger. Further, the discharge amount value at the rotation speed of about 22 rotations / minute is about 0.07 m in this embodiment.
While it is 3 / min, in the conventional example, it is a small amount of about 0.04 m 3 / min because crushed rock wool adheres to the wall surface of the material supply member 51. On the other hand, when the number of revolutions is higher than that, the ejection amount is hardly increased in the conventional example, whereas in the present embodiment, the ejection amount is increased as the number of revolutions is increased.
