In addition, terms to be described below are terms defined in consideration of functions in the present invention, which may vary according to the intention or convention of a user or an operator. Therefore, definitions of these terms should be made based on the contents throughout this specification.

1 is a plan view showing a water vapor removal apparatus according to an embodiment of the present invention, Figure 2 is a view showing the internal structure of the water vapor removal apparatus according to an embodiment of the present invention.

1 and 2, the water vapor removal apparatus 100 according to an embodiment of the present invention is the inlet 110, the first ejector 120, the first hood 130 and the first The discharge unit 140 is included.

According to this embodiment, the water vapor removal apparatus 100 is installed on the side of the material (1) to be transported by a feed roller (not shown), the inlet 110, the first ejector unit 120, and One discharge unit 140 is formed integrally with one pipe (pipe).

Compressed air flows into the inlet 110. The inlet 110 includes an inlet pipe 111 and the jet fan 113.

The inside of the inlet pipe 111 is formed with a hollow for the compressed air flows into. One side of the inlet pipe 111, that is, the inlet side end is opened toward the outside, the other side of the inlet pipe 111 is in communication with the first ejector unit 120 to be described later.

The jet fan 113 is installed at the inlet side end of the inlet pipe 111. The jet fan 113 is rotated at the inlet side end of the inlet pipe 111 to introduce compressed air into the inlet pipe 111. The compressed air introduced into the inlet pipe 111 by the jet fan 113 is transferred to the first ejector unit 120 through the inlet pipe 111.

The first ejector unit 120 is connected to the inlet 110. The first ejector unit 120 is connected to the other side of the inlet pipe 111 to communicate with the inside of the inlet 110, the pressure inside the passage of the compressed air flowing through the inlet 110 is lowered. . As an example, the first ejector unit 120 includes an inlet pipe 121, a discharge pipe 123, and a suction pipe 125.

The inlet pipe 121 is located adjacent to the inlet 110. The inlet pipe 121 increases the speed of the compressed air moved to the discharge pipe 123 by narrowing the width of the flow path of the compressed air transferred from the inlet 110, that is, the inlet pipe 111, and thus the discharge pipe. A pressure drop is generated in the furnace 123. As an example of such an inflow pipe 121, an orifice member is applied in this embodiment, but is not limited thereto.

Discharge pipe 123 is located between the inlet pipe 121 and the first discharge unit 140 to be described later connects the inlet pipe 121 and the first discharge unit 140. The discharge conduit 123 is formed to have a wider channel width than the inlet conduit 121, and a pressure drop is generated in the discharge conduit 123 due to the compressed air passing through the inlet conduit 121.

The suction pipe passage 125 is connected to the discharge pipe passage 123. A suction force is generated in the suction pipe line 125 when the pressure drop of the discharge pipe line 123 occurs, and the suction pipe line 125 sucks water vapor sucked through the first hood part 130 to be described later toward the discharge pipe line 123. do.

The first ejector unit 120 having the structure as described above, when the compressed air flowing through the inlet 110, the internal pressure is lowered to generate a suction force to suck the water vapor through the suction pipe line 125, The sucked water vapor is discharged to the first discharge part 140 through the discharge pipe 123.

The first hood unit 130 is installed toward the material 1 so that the water vapor on the material 1 is sucked into the first ejector part 120 to suck the water vapor on the material 1.
