In some cases, the dust collecting hood 14 may be provided with a separate suction fan and a dust collecting device to be configured to be collected separately from the scattering dust introduced through the passage 51 of the dust collecting tube 50. At this time, the passage 52 of the dust collecting hood 14 and the dust collecting tube 50 is in communication with the dust collecting device 60 through the dust collecting pipe 15.

Referring to the operation of the scattering dust removal bulk hopper system according to an embodiment of the present invention configured as described above are as follows.

First, in the state where air is injected through the air nozzle 31 of the air curtain body 30 to form an air curtain on the inner side of the air curtain body 30, the grab 4 of the air curtain body 50 is used. A large amount of contents 3 such as grains is introduced into the inner portion. The injected contents 3 pressurizes the opening and closing member 23 of the barricade 20 inside the hopper body 10, as shown in FIG. 2, so that the opening and closing member 23 opens the through hole 22. 3) is passed to the lower portion of the hopper body 10 through the barricade 20. At this time, after the contents 3 have passed, the opening and closing member 23 is restored to its original shape by the elastic restoring means to close the through hole 22, and thus the contents passing through the barrique 20 are hopper bodies 10. Scattering dust generated while colliding with the inner circumferential surface of the) prevents the opening and closing member 23 from being opened due to a slight pressing force for pressing the opening and closing member 20 from the lower side to the upper side. Since the structure of opening the ball 22, the scattering dust is not able to penetrate the barrier 20 to rise to the upper side of the hopper body (10). In addition, as shown in Figure 2, even if the pressure from the lower side of the opening and closing member 23 to the upper side, since the opening and closing member 23 is caught in the adjacent support 21 can no longer be rotated, the opening and closing member ( The through hole 22 is not opened by the pressure applied from the lower side of 23).

However, a small amount of scattering dust generated when the contents 3 press the opening / closing member 23 and the through-hole 22 is opened rises to the upper side of the hopper body 10 through the open-through hole 22. Done. At this time, the scattered dust raised to the center of the hopper body 10 is blocked by the air curtain formed inside the air curtain body 30 to join with the scattered dust raised along the inner circumferential surface of the hopper body 10, The scattering dust is blocked by the blocking wall 13 of the inclined portion 11 and collected while being introduced into the dust collecting hood 14 through the through hole 12 of the inclined portion 11.

On the other hand, the slide plate 41 of the discharge pipe 40 is rotated to communicate the discharge pipe 40 with the hopper body 10, the contents passing through the barricade 20 of the hopper body 10 is discharge pipe 40 Is loaded into the transport vehicle (1). Then, the dust scattered by the contents 3 dropped into the transport vehicle 1 is raised through the passage 52 while hitting the inner surface of the blocking wall 51 of the dust collecting tube 50 to the dust collector 60. It is collected as it flows in.

Therefore, when the bulk content 3, such as grain or construction waste, is loaded into the transport vehicle 1 through the bulk hopper system for scattering dust removal of the present invention, the scattering dust does not flow out of the hopper body 10. In addition, it does not leak to the outside of the discharge pipe 40 has the advantage of preventing air pollution. In addition, since the gap formed in the air curtain due to the nozzle hole formed in the air curtain body of the conventional bulk hopper does not exist in the present invention, there is an advantage that it is possible to more reliably remove dust. Also, unlike the conventional dust scattering dust generated while the contents 3 are discharged through the discharge pipe, in the present invention, the scattering dust is formed by the difference in diameter between the dust collecting pipe 50 and the discharge pipe 40. Since dust is introduced into the dust collecting device 60 through), it is possible to more reliably remove scattering dust.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. It will be apparent to those of ordinary skill in the art.
