Description

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a basalt processing apparatus,

The present invention relates to a basalt processing apparatus and a basalt product processed using the apparatus. More particularly, the present invention relates to a basalt processing apparatus capable of processing a collected basalt to the nearest natural state to maximize a sense of a rough stone, ≪ / RTI >

Basalt is a rock formed by hardening after magma emerges outward and suddenly cools. There are many irregular pores inside and outside.

These unique and unusual appearance and pore-forming characteristics make it possible to produce various shapes such as stone, pollen, tile, block stone, and brick.

However, these basalt rocks have a disadvantage in that it is difficult to precisely process them due to brittle fracture in the processing operation due to the porous material property.

As a result, souvenirs and souvenirs made of basalt are processed as they are without any change in color and have a lot of porosity, and their shapes and facial expressions are generally uniform. In addition, products made of cast iron by kneading stone powder and adhesive Mostly.

In addition, even in the case of gem stone processing, it is not enough to process artworks and landscapes that are artistic and aesthetically pleasing, such as cutting, etc. If the processing is repeated several times through ordinary tools, the texture of the natural stone is damaged, There is a problem that many basalt gemstones to be cut and discarded during the processing are polluted and the work site and the surrounding are contaminated due to dust during the basalt processing.

Regarding this, a technique related to basalt processing is disclosed in Japanese Patent Registration No. 1147321, which discloses a finishing method using sandblast, and Japanese Laid-Open Patent Application No. 2005-0045556 discloses a method for realizing basalt-like artificial stones closest to basalt Lt; / RTI >

In addition, there are many other technologies applied to basalt, such as Patent No. 0790205, No. 0055242, No. 0311183, and the like.

However, when cutting the natural basalt, the texture of the cut surface is lowered. Especially, when dust is generated during processing, especially dust blasting, huge dust is generated. These dusts block the micro pores of the basalt, Not only does it not feel like a rough stone, but also has a disadvantage in that the color is changed and the contrast is not clear and the value of the product is lowered accordingly.

In addition, after the sand blast treatment, there are many piercing and sharp parts locally, and it is not possible to postpone it.

In other words, the above-mentioned simple sand blast process alone can not increase the product value, and in order to increase the product value, post-processing is required, which is very costly and time-consuming.

Moreover, the fine pores blocked by the dust change not only the color but also the smoothness of the surface due to the clogging of the pores, making it impossible to save the natural beauty, and the dust trapped in the fine pores is almost fixed Therefore, it is urgently demanded to improve it because it is not a nature that can be taken out simply by collecting dust.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Before describing the present invention, the following specific structural or functional descriptions are merely illustrative for the purpose of describing an embodiment according to the concept of the present invention, and embodiments according to the concept of the present invention may be embodied in various forms, And should not be construed as limited to the embodiments described herein.

In addition, since the embodiments according to the concept of the present invention can make various changes and have various forms, specific embodiments are illustrated in the drawings and described in detail herein. However, it should be understood that the embodiments according to the concept of the present invention are not intended to limit the present invention to specific modes of operation, but include all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.

As shown in FIG. 1, the basalt processing apparatus according to the present invention includes a roller table 200 for transporting a processed basalt sheet 100.

The roller table 200 includes a plurality of rolls arranged horizontally and horizontally on a table and includes a concept of a kind of conveyor, and is preferably rotated at a speed of 1-5 m per minute.

Therefore, the working basalt 100 seated on the roller table 200 is conveyed along the roller table 200 at the same speed in synchronism with the rotation speed of the roller table 200.

In a part of the length of the roller table 200, a shot blast chamber 300 and a high-pressure water surface treatment chamber 400 are arranged in parallel in the traveling direction.

In particular, the two chambers are configured to be closed so that the dust generated in the shot blast or the wash water scattered in the washing process can be recovered from the confined space without flowing out.

A shot blast unit 310 is installed in the shot blast chamber 300 and a high pressure water surface treatment unit 410 is installed in the high pressure water surface treatment chamber 400.

Further, a dust collector (D) is further provided on the upper side of the shot blast chamber (300) to absorb and remove a large amount of dust generated during the shot blasting process.

In this case, the shot blast unit 310 is formed by strongly projecting a large amount of round beads G of stainless steel or iron having a diameter of 1-5 mm at a speed of 90 m / sec or less, To modify the surface.

In this case, the term "surface modification" refers to a process of forming a dimple having a random shape on the surface of the processed basalt 100 by colliding with a projected bead G on the surface of the processed basalt 100 to form a kind of an artificial roughness, Home).

When a large amount of projected chain beads G are projected to modify the surface, the dimples are formed randomly, so that the formed dimples form a surface close to all other natural stones in depth, size, shape, shape and the like.

On the other hand, in the case of the conventional sandblast, since the sand is projected, the depth, size, shape and the like of the dimple are small and minute, and a part of the sand remains in the micro pores. However, in the present invention, .

On the other hand, the high-pressure water surface treatment unit 410 sprays high-pressure washing water of about 50-5000 bar on the surface of the shot blasted processed basalt to wipe sharp portions to soften them and to remove all the dust trapped in the micropores It is a means of processing so that the color appears clearly while utilizing the surface texture.

6, it can be seen that the surface of the processed work stone is processed at almost the same level as the texture, pore and color of the rough stone.

Particularly, as clearly shown in FIG. 7, the basalt processed by the simple cutting method completely blocks the fine pores of the dust as shown in the photograph on the lower side, so that the color is turbid and not clear, However, the basalt processed according to the present invention can be easily confirmed that the color is clear and the feeling is close to the natural stone since the micropores are alive and the surface is modified as in the photograph of the upper side.

2, the shot blast unit 310 may be implemented in various forms.

2, the shot blast unit 310 includes a hopper 312 filled with beads G, and a plurality of spray holes (not shown) connected to the lower end of the hopper 312, A screw feeder 318 incorporated in the feeding pipe 316 and a driving motor 320 driving the screw feeder 318 to rotate the screw feeder 318 have.

At this time, a slide gate 314 may be provided at the lower end of the hopper 312 to selectively block the flow of the charged beads G.

The screw feeder 318 rotates at a high speed according to the rotation speed of the driving motor 320 and the beads G induced and introduced into the feeding pipe 316 are sprayed at a high speed through a spray hole, 100 to process the surface of the processed basalt 100.

2 (b), the shot blast unit 310 uses a pressurizer 330 instead of the screw unit 318 and the drive motor 320 to pressurize the high pressure from the upper part of the hopper 312 So that a large number of beads G can be projected at a high speed through the injection hole of the feeding pipe 316. [

3 (a), the high-pressure water surface treatment unit 410 includes a cleaning water pipe 412 and an injection nozzle 414 formed on a part of the periphery of the cleaning water pipe 412 .

At this time, the injection nozzle 414 may be a simple linear type or a spray type.

Then, the washing water injected through the injection nozzle 414 is shot blasted, and the unfinished dimples, particularly the sharp edges, are worn down to make it gentle and smooth. In addition, the dust contained in the micropores is washed cleanly do.

Therefore, it not only improves the texture but also brings back the color.

As another example, as shown in FIG. 3 (b), the spray nozzle 414 is not simply sprayed. Instead, the spray nozzle 412 may be rotated at a predetermined radius while spraying high- 420) may be used.

4 and 5, the rotatable nozzle 420 includes a cylindrical nozzle body 422 whose tip is enlarged like a fallopian tube, and a cylindrical body 422 fastened to the upper end of the nozzle body 422, A sealing member 426 provided on the inner side of the impactor tube 422 of the nozzle body 422 and a portion of the lower end of the sealing member 426 inserted into the hole formed at the center of the sealing member 426 And a fluid body 428 having a spray hole H formed therein.

In this case, the hole of the sealing piece 426, in which a lower end portion of the fluid 428 is fitted, is configured to have a protrusion B in the form of a boss in order to minimize the gap with the outer circumferential surface of the fluid 428 .

Further, the supply passage L is eccentrically machined so as to be ejected in one direction.

Therefore, when high-pressure water is supplied, the high-pressure water forms a vortex in the nozzle body 422 because of the shape and position of the supply passage L.

In particular, since the high-pressure water is blocked downward by the sealing member 426, the water is not discharged immediately but is heated inside the nozzle body 422, and the vortex generated in the process rotates the fluid body 428.

At this time, since only a part of the lower end of the fluid body 428 is held in the hole of the sealing piece 426, the fluid body 428 performs a so-called washing motion that rotates like a top.

At the same time, the high-pressure water that has flowed in is injected at high pressure toward the processed basalt 100 through the injection hole H of the fluid 428.

Therefore, the high-pressure water hits the surface of the processed basalt 100 while drawing a certain radius. The hitting is not continuously performed based on a specific point, but is intermittently applied The impact effect is remarkably improved.

In other words, once hit at one point, it comes back again and strikes again, and then comes back again and strikes at intervals in the form of striking, so dust that has been charged in micropores can easily come out while shaking, So that it can be smoothly processed.

Moreover, since it has a radius of rotation, it can be wiped clean over a wider range, resulting in improved efficiency.
Such a basalt product processed by the shot blast unit 310 and the high-pressure water surface treatment unit 410 may include a shot blasted surface and a high-pressure water surface treated surface.
Specifically, the shot blasted surface includes a hopper 312 having a diameter of 1-5 mm and filled with a large number of beads G made of stainless steel or iron material, A circular feed pipe 316 connected horizontally along the feed pipe 200 and having a plurality of injection holes formed therein, a screw feeder 318 installed in the feed pipe 316 as a whole, a screw feeder 318, And a slide gate 314 for selectively blocking the flow of the plurality of beads G charged at the lower end of the hopper 312. The drive motor 320 Blast unit 310 that projects the plurality of beads G guided into the feeding pipe 316 through the injection hole as the screw feeder 318 rotates at a high speed have.
The high-pressure water surface-treated surface is provided with a washing water pipe 412 for supplying high-pressure water, and a large number of longitudinally arranged water pipes 412 for rotating the high- The rotatable nozzle 420 includes a cylindrical nozzle body 422 having a distal end protruding like a fallopian tube and a cylindrical body 422 fastened to the upper end of the nozzle body 422 and having a high- And a sealing member 426 provided on the inside of the tubular bulb of the nozzle body 422. The sealing member 426 has a lower end portion fitted in a hole formed at the center of the sealing member 426, A boss B-shaped protrusion B (not shown) is formed in the hole 428 of the sealing member 428 in which the injection hole H is formed and the lower end portion of the fluid member 428, And the sealing member 426 having the protruding portion B formed therein, A high pressure water flows in the nozzle body 422 and a vortex is formed in the nozzle body 422 so that the fluid 428 rotates while being fitted in the hole of the closing piece 426, Blast machined surface by a high-pressure water surface treatment unit 410 that rotates and injects water.

As described above, the present invention not only performs a shot blast process, but also has the same effect as automatically finishing the surface of the processed basalt 100 by using the high-pressure water to clean the surface of the processed basalt 100, thereby maximizing the efficiency.
