The overall shape of the air nozzle 320 is approximately the shape of a figure 8 in which two spheres overlap in an intersection state, and for explanation purposes, they are called the first nozzle 320a and the second nozzle 320b.

The first nozzle 320a is rotatably installed along the inner peripheral surface of the hemispherical groove 322a-1. Accordingly, the hemispherical groove 322a-1 is installed to prevent the first nozzle 320a from leaving the first nozzle 320a. ) can be formed with a groove inner diameter that can include a radius or more.

In addition, the second nozzle 320b is also preferably spherical and continuously formed integrally with the first nozzle 320a, and is preferably formed to be somewhat smaller than the diameter of the first nozzle 320a, and may be installed to protrude forward.

Accordingly, the spray angle of the second nozzle 320b toward the outside may vary depending on the rotation of the first nozzle 320a.

An internal air slit (332a) of a length corresponding to the air slit (330a) may be formed in the double horizontal bar 332 in the longitudinal direction.

Accordingly, the internal air slit 332a communicates with one of the air slits 330a depending on the degree of rotation of the double horizontal bar 332, so that air can be sprayed.

When the internal air slit (332a) communicates with the air slit (330a) formed relatively above the center, air is sprayed upward, and conversely, the air slit (330a) formed below the center and the internal air slit (332a) are When connected, air may be sprayed downward.

In order to explain the rotational operation of the double horizontal bar 332, it will be described with reference to lines D-D in FIG. 8.

The inner diameter of one end of the double horizontal bar 332 is reduced to form a step portion 332b, and a rotation knob 334 may be installed in the space between the step portion 332b and the horizontal bar 330.

The operation of the work table capable of removing dust and blocking scattering according to another embodiment of the present invention configured as described above will be described with reference to FIG. 3 or FIG. 9.

Activated carbon dust scatters as the worker fills the honeycomb-structured mold (1) with activated carbon on the work table (100) and attaches filter paper (2) to both sides.

At this time, as the intake fan 220 is driven, dust flows into the exhaust duct 210 through the intake port 112, and the dust passing through the exhaust duct 210 is collected in the collection unit 230 and removed or reused.

In this process, as shown in FIG. 9, the air curtain device 300 forms an air curtain in a certain range by spraying air forward from the top and both sides centered on the worker, thereby preventing scattering of dust and controlling the range of the air curtain. Dust remaining inside can be more easily discharged through the intake port 112.

In detail, the height of the vertical bar 312 and the integrated horizontal bar 330 can be adjusted by adjusting the length of the fixed bar 311 fixed to the dust suction part 110.

When the fixing tip 317 installed on the vertical bar 312 is pressed, the fixing tip 317 compresses the spring 315 and lowers or withdraws the vertical bar 312 while it is located in the space 314. When positioned in one of the fixing holes 311a, the fixing tip 317 moves by the expansion of the spring 315, and a portion of the end protrudes into the fixing hole 311a, thereby separating the vertical bar 312 from the fixing bar 311. can be fixed.

And the operation of the air curtain is that the air generated by the operation of the air generator 350 passes through the air duct 340 and the fixed bar 311 to the air nozzle 320 of the vertical bar 312 and the horizontal bar 330. It can be sprayed through the air slit (330a).

Each air nozzle 320 can be adjusted to an injection angle, and when the second nozzle 320b is rotated while being held, the first nozzle 320a is aligned with the hemispherical groove 322a-1 of the bracket 322. The angle changes as it rotates within the clearance space 323, and it is sprayed in a straight line through the hemispherical hole (322a-2) and the air hole (320c).

In addition, the spray angle can be adjusted on the horizontal bar 330, which means that when the user holds the rotation knob 334 and rotates it in a certain direction, the internal double horizontal bar 332 of the horizontal bar 330 rotates together, When the internal air slit 332a of the double horizontal bar 332 communicates with a required slit among the plurality of air slits 330a, the operation of the rotary knob 334 stops.

The internal air slit 332a and one air slit 330a are in communication so that air can be sprayed.

As described above, flying dust can be efficiently removed to create a safe working environment.

In the above, specific embodiments are shown and described. However, it is not limited to the above-mentioned embodiments, and those skilled in the art can make various changes without departing from the gist of the technical idea of the invention as set forth in the claims below. .
