Hereinafter, the driving unit 400 will be described in detail.

The driving unit 400 is connected to the scraper device 200 and serves to rotate and move the scraper device 200 in the inner space 130, and the driving motor unit 410 and the rotating unit 420 ) Can be included.

First, the drive motor unit 410 may be configured to include a drive motor 411 and a drive shaft unit 412 as a drive source for rotating the rotation unit 420.

The central shaft 4122 is connected to the drive shaft 4121 to rotate in conjunction with the rotation of the drive shaft 4121 and is connected to the rotation unit 420 to rotate the rotation unit 420.

Meanwhile, the drive shaft part 412 may transmit the rotational motion of the drive shaft 4121 to the central shaft 4122 through a connection gear.

In the drawing, the connecting gear is composed of a bevel gear by a drive shaft 4121 and a central shaft 4122 arranged perpendicular to each other. However, as an example, when the drive shaft 4121 and the central shaft 4122 are arranged parallel to each other, a spur gear may be applied, as well as various other configurations may be applied.

The prime mover 421 is axially connected to the central shaft 4122 of the driving motor unit 410 and rotates, and a driving screw is formed on an outer circumferential surface thereof.

The driven gear 422 is configured to rotate in conjunction with the rotation of the prime mover 421 by forming a driven screw that engages with the drive screw, and is coupled to the rotation frame 211 to rotate the rotation frame 211 .

On the other hand, the driven gear 422 is configured as an internal gear so that the prime mover 421 is located on the inner circumferential side, and transmits the rotational force of the prime mover 421 and may be formed to have an eccentric force during rotation. .

Referring to FIG. 6, in the drive unit 400, the rotation center P2 of the driven gear 422 is eccentric with respect to the rotation center P1 of the prime drive gear 421, and the driven gear 422 It may be configured to rotate eccentrically with respect to the prime mover gear (421).

Accordingly, the driven gear 422 is positioned so that the rotation center P2 is eccentric with respect to the rotation center P1 of the prime mover 421, so that the position of the driven gear 421 changes repeatedly while rotating. It will rotate like a shake.

On the other hand, the shaking of the driven gear 422 also affects the motion of the scraper device 200 connected to the driven gear 422, so that when rotating, the scraper device 200 moves toward the reaction body 100 in a specific direction. It generates a concentrated pressing force.

This pressing force allows the scraper 220 to more effectively scrape the cured reactant material by being fixed to the reaction tower body 100, so that the scraper 200 adheres to the inner surface of the reaction tower body 100. It makes it possible to improve the removal effect.

As described above, the driving unit 400 is such that the prime mover 421 and the driven gear 422 are eccentric to each other, so that the scraper device 200 generates a pressing force toward the reaction tower body 100 when rotating. By doing so, it is possible to more effectively remove the reaction material attached to the inner surface of the reaction tower body 100.

Hereinafter, the moving unit 600 will be described with reference to FIG. 7.

The reaction tower for the incineration facility allows the scraper device 200 to move along the longitudinal direction of the reaction tower body 100 so that the scraper device 200 moves a wider area with respect to the inner wall surface of the reaction tower body 100 It may be configured to remove the reactant.

Accordingly, the reaction tower for the incineration facility is interposed between the driving motor unit 410 and the rotation unit 420, and further includes a vertical movement unit 600 configured to move in the vertical direction according to the driving of the driving motor 411. It can be configured to include.

The moving unit 600 may include a first bevel gear 610, a second bevel gear 620, a first spur gear 630, and a second spur gear 640. .

The first bevel gear 610 is configured to rotate by being axially coupled to the drive shaft 4121 of the drive motor 411 and to rotate by being coupled to the drive shaft 4121 in a horizontal direction in the drawing.

The second bevel gear 620 rotates by meshing with the first bevel gear 610, and a rotation shaft 632 is axially coupled.

Here, the rotation shaft 632 extends in a downward direction in which the rotation unit 420 is positioned with respect to the second bevel gear 620, and is disposed vertically with respect to the horizontal drive shaft 4121 to rotate.

The first spur gear 630 is axially coupled to the rotation shaft 632 and rotates about the rotation shaft 632, and a first screw portion 631 is formed on an outer circumferential surface thereof.

The second spur gear 640 is formed with a second screw part 641 meshing with the first screw part 631 on an outer circumferential surface to rotate in conjunction with the rotation of the first spur gear 630, and the central axis toward the lower surface thereof. When the 4122 is shaft-coupled and rotates, the central shaft 4122 is configured to rotate.

On the other hand, the second screw part 641 not only rotates by meshing the second spur gear 640 with the first spur gear 630, but also allows the second spur gear 640 to move vertically when rotating. Can be configured.

To this end, the second screw portion 641 is formed to have a vertical curve pattern with respect to a partial area of the outer peripheral surface of the second spur gear 640, and the second spur gear 640 is rotated by the rotation of the first spur gear 630. ) Is configured to reciprocate in the vertical direction along the second screw portion 641.

Here, the vertical curve pattern may be continuously formed in a parabolic shape from the top to the bottom of the second spur gear 640.

8 is a view showing the vertical curve pattern of the second screw portion 641. Referring to the drawing, the second screw portion 641 sets various cycles of the vertical curve pattern in response to the number of vertical movements of the second spur machine. I can.

For example, (a) of FIG. 8, the second screw part 641 is reciprocated once when the second spur gear 640 rotates once, and the second screw part 642 of (b) is a second spur gear 640 ) Is configured to reciprocate twice for one rotation.

Here, the vertical curve pattern of the second screw portion 641 may be variously set in consideration of the size of the second spur gear 640 and the size of the reaction tower body 100.

Although not shown, the second spur gear 640 may have a support shaft coupled to the upper surface to stably support a position during vertical movement. At this time, the support shaft can be applied to a variety of configurations that can achieve the above object, such as a pair of support rods having a sliding groove and a sliding protrusion slidably fitted thereto so as to allow the vertical movement of the second spur gear 640 Do.

Meanwhile, in the rotation unit 420, the rotation period of the rotation frame 211 is referred to as N1, the rotation period of the prime gear 421 is referred to as N2, and the rotation period of the second spur gear 640 is referred to as N3. In this case, it is preferable that any two or more of N1, N2, or N3 are configured not to be an integer multiple of each other.

Here, when the rotation period becomes an integer multiple, it means that it returns to the same starting point. Therefore, the fact that the rotation periods are not integral multiples of each other means that the rotation does not return to the same starting point and starts from different starting points for each rotation period.

And the configuration so that any two or more of the N1, N2, or N3 are not integer multiples of each other means, in detail, that the N1 and N2, the N1 and N3, and the N2 and N3 are not integer multiples of each other.

Hereinafter, based on the above, the relationship between the rotation period N1 of the rotation frame 211 and the rotation period N2 of the prime mover 421 and the rotation period N1 of the rotation frame 211 And the relationship between the rotation period N3 of the second spur gear 640 and the rotation period N2 of the prime mover 421 and the rotation period N3 of the second spur gear 640 Let's look at each.

First, looking at the rotation period (N1) of the rotation frame 211 and the rotation period (N2) of the prime mover 421, the rotation period (N1) of the rotation frame 211 and the prime mover 421 It is preferable that the rotation period N2 is not an integer multiple of each other.

This is, when the rotation period of the rotation frame 211 and the rotation period of the prime mover 421 are an integer multiple, when the rotation frame 211 is rotated, the direction of eccentricity is at specific positions on the rotation radius of the rotation frame 211. This is because it is fixed, and the position where the pressing force by eccentricity is generated is limited to specific positions.

Thus, as described above, the rotation period (N1) of the rotation frame 211 and the rotation period (N2) of the prime mover 421 are configured not to be an integer multiple of each other, so that they are not synchronized and the position of the pressing force is evenly distributed. It can be prevented from being pressed only on a specific part of the body 100.

Second, it is preferable that the rotation period N1 of the rotation frame 211 and the rotation period N3 of the second spur gear 640 do not become an integer multiple of each other.

This is, when the rotation period of the second spur gear 640 for vertically moving the scraper device 200 and the rotation period of the rotation frame 211 are multiples, the scraper 220 rotates along the same vertical movement path. This is because the reactants are removed substantially only for a specific portion corresponding to the movement path of the scraper 220.

Therefore, the rotation period (N1) of the rotation frame 211 and the rotation period (N3) of the second spur gear 640 are not multiples of each other so that they are not synchronized, and the position of the scraper 220 is It is evenly distributed in the vertical movement position of the scraper 220 when rotating by making the vertical position different, so that a larger area can be scraped with respect to the inner surface of the reaction tower body 100 without being located only in a specific position on the rotation cycle. have.

Third, it is preferable that the rotation period N2 of the prime mover 421 and the rotation period N3 of the second spur gear 640 do not become an integer multiple of each other.

This means that when the rotation period N2 of the prime mover 421 and the rotation period N3 of the second spur gear 640 are an integer multiple, the direction of the eccentricity during rotation is fixed to specific positions on the vertical line. This is because the vertical position where the pressing force is generated is limited to specific positions.

For this reason, the rotation period (N2) of the prime mover 421 and the rotation period (N3) of the second spur gear 640 are configured not to be an integer multiple of each other, so that they are not synchronized and the position of the pressing force is evenly aligned on a vertical line. It can be distributed so that it is not pressurized only in a specific part of the reaction tower body 100.

The present invention has been described with reference to the embodiments shown in the drawings, but these are merely exemplary, and those of ordinary skill in the art will appreciate that various modifications and equivalent other embodiments are possible therefrom. Therefore, the true technical protection scope of the present invention should be determined by the technical spirit of the appended claims.
