Abstract

PURPOSE:To enhance the effect of breaking a bridge with an air jet stream by supplying an air jet stream from an air jet nozzle for breaking a bridge of granular powder accompanied by air and granular powder supplied from other portions through a supply path. CONSTITUTION:In case of opening a discharge port gate 8 of a hopper 7 to feed out the stored granular powder 9 to a discharge chute pipe 11, if granular powder 9 builds a bridge 9a not to be discharged, an air jet stream 13 is sprayed from an air jet nozzle 12 to the bridge 9a to be broken. At this time, the air jet stream 13 is forced to pass at high speed in one end portion of a pipe 10 connecting the side wall portion of the hopper 7 to the side wall portion of the discharge chute pipe 11, so that air and granular powder 9 in the pipe 10, the discharge chute pipe 11, and in the lower portion of the hopper 7 are sucked in the air jet stream 13 to be accompanied therewith. Thus, the apparent amount of air is increased to reliably break the bridge 9A with strong force.

FIG. 1 shows a conventional example, and shows a general configuration in which a bridge breaking mechanism air jet nozzle is provided in the hopper portion of a silo. In the figure, (1) is the hopper at the silo discharge port, (2) is the discharge gate for discharging the stored granular material (3) from the hopper (1), and (41Vi) is the hot spring directly below the discharge log gate (2). An air jet nozzle (5) for breaking bridges is installed with its nozzle opening facing the side wall of the phantom (5), and a discharge chute pipe (5) is connected to the lower end of the hopper (1). When (3) is discharged by opening the discharge port gate (2), if the powder (3) cannot be discharged due to the crosslinking phenomenon, the crosslinked surface diagonally upward from the nozzle opening of the air jet nozzle (4) The bridge (3A) is destroyed by blowing an air jet stream (6) towards the air jet nozzle (4).
Since the air jet flow (6) entrains only a small amount of surrounding air and powder particles (3), there is a problem that it would be difficult if only the air outside the air supply had the force to destroy the bridge (3A). Therefore, the destructive force of the crosslink (3A) was insufficient.

The purpose of the present invention is to solve such problems, and when the powder or granules stored inside a powder or granule storage tank cannot be discharged due to the crosslinking phenomenon at the time of dispensing, the bridge breaking method is performed by blowing an air jet stream onto the crosslinked surface. A path for supplying the stored powder or granules or the same powder as the stored powder is provided in communication with the air jet path of the air jet nozzle for crosslinking, and the air jet flow of the air jet nozzle for breaking bridges is This objective is achieved by providing a bridge breaking device in a powder storage tank or the like that is configured to entrain powder and granules. In addition, the effect and effectiveness of crosslinking destruction can be increased by increasing the number of particles, and the destructive force caused by the mixing of powder and granular materials with an air jet stream can be significantly improved compared to conventional methods.

The operation of this configuration will be explained next. Stored powder (9)
When the powder (9) cannot be discharged due to the crosslinking phenomenon when the powder (9) is discharged by opening the discharge port gate C8), an air jet stream 1131 is generated from the nozzle opening of the air jet nozzle (121) diagonally upward toward the bridge surface. Crosslink by spraying (9A)

At this time, as shown in FIG. 1, unlike the -# device G, the air jet flow (13) passes through one end Hg of the pipe 00 at high speed, so the air in the pipe Gll and the discharge chute pipe (river, ho... The air in the lower part of the buckwheat (7) is also sucked into this air jet stream (13) and entrained.Therefore, the apparent amount of upper air supply increases, The bridge (9A) is destroyed with a strong force.
According to an experiment using A, the force of the air jet flow at the same position from the nozzle opening is the same when air is entrained and when it is not entrained, even though air is entrained as in the present invention. The value was about 30 to 50% higher than that in which no air was entrained.

Furthermore, the air jet from the air jet nozzle (121) comes to accompany the air sucked into the air jet stream (131, and becomes mixed inside the air jet stream □3). Powder (
9B) collides, and the destructive force of the crosslink (9A) further increases. In this regard, according to the apparatus a of FIG. 1, the crumbling powder (3) should be entrained only in the decelerated part of the outer periphery of the air jet flow (6). It is not possible to obtain the speed and penetration force required for the collision of the particles (3).

This will prevent the powder (9) from entering into the air jet nozzle U21 when the discharging is proceeding smoothly. Since the side wall of the hopper (7) is connected to the side wall at approximately the same angle of inclination as the side wall of the hopper (7), the powder (9) does not remain inside the pipe qU, and the air jet nozzle (121) During use, the powder (9) that has entered the pipe aa will be guided to the discharge chute pipe fil).

FIG. 3 shows another embodiment, in which the pipe (I) in FIG.
The other end of G is connected to a separate container (l151) containing the same powder and granular material as the stored powder and granular material (9) in the hopper (7), without connecting it to the side wall of the discharge chute pipe (I). The other configuration is the same as the device in Figure 2, so
An operation similar to that of device H in FIG. 2 can also be performed with such a configuration, the explanation of which will be omitted. In the case of this embodiment, if an air suction port is provided at an appropriate location of the pipe αO, the flow of the air jet flow (131) can be made smooth.

As described above, according to the present invention, since the air in the supply route can be entrained in the air jet stream of the jet nozzle, the apparent amount of upper air supply is increased, further increasing the effect and effectiveness of crosslinking destruction. Furthermore, since the powder and granules in the supply route can be entrained in the air jet stream, the destructive force caused by mixing the powder and granules can be significantly improved compared to conventional methods.
