Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative material for use in the construction or construction of used refractory bricks of an industrial furnace used for refining metal or associated equipment, and a method for producing the same.

[0002]

2. Description of the Related Art Refractory bricks are used as linings in industrial furnaces such as blast furnaces and coke ovens used for refining metals and ancillary facilities, but these refractory bricks are partially broken after a certain period of operation. It is exhausted and is demolished, and a new brick is constructed. On the other hand, as disclosed in, for example, Japanese Patent Laid-Open No. 49-120258, a method has been proposed in which crushed stone is put in a rotary drum and the corners are processed into gravel gravel. There was no disclosure of producing

[0003]

In addition, the used bricks have not been used effectively at present, and most of them are used as embankment materials for dumping or landfill as industrial waste. In addition, when there is no landfill or dumping place, it is currently piled up in the demolition place, and there is a problem that it is not preferable in terms of generation of dust and the like and aesthetics. The present invention has been made in view of such circumstances, and appropriately crushes and polishes these used bricks, and decorative materials used for construction or construction using used refractory bricks that are effectively utilized as resources and It is an object to provide a manufacturing method thereof.

[0004]

A method according to the above-mentioned object.
The decorative material used for construction or construction using the used refractory brick as a raw material is a crushed and refined used refractory brick to remove the molten component and to classify it into a round object of about 20 to 120 mm. Become. Then, according to the above-mentioned object, the method for manufacturing a decorative material used for construction or construction using a used refractory brick as a raw material is a rough crusher after roughly dividing a used refractory brick with a pyrene, a breaker or the like. By crushing so that the crushed material having a particle size of 20 to 120 mm becomes the main component, and then sieving them, and then throwing the sieving material into a chamfering device equipped with rotation and / or vibration, Is formed and is molded into a round shape. Here, the piren is a means for dropping the weight from the upper part to the used refractory bricks and crushing it, and the breaker is a means for attaching a crushing rod to the heavy equipment arm and roughly breaking the object by hydraulic pressure or vibration. . The coarse crusher generally means a machine, such as a jaw crusher, for further crushing the roughly-used used refractory brick into smaller pieces.

[0005]

In the decorative material using the used refractory bricks as a raw material according to claims 1 and 2 and the method for producing the same, the used refractory bricks are crushed by a pyrene or breaker and roughly crushed. It should be of a size that can be transported, and it will be applied to the subsequent coarse crusher. In the coarse crusher, the crushed product is crushed to a particle size of 20 to 120 mm, and the crushed product is classified with a sieve, and the crushed product is put into a chamfering device that applies rotation and / or vibration.
As a result, the molten refractory brick having no strength is removed, and since the corner portions are rounded, the refractory brick is molded into a round shape having the color of the used refractory brick. Therefore, when this is mixed with concrete and used, a stone having a color is used, and for example, by cutting the concrete containing this used refractory brick, a clearer pattern appears. Also, by using it as a paving stone instead of pebbles, a different color tone from natural stone is produced.

[0006]

Embodiments of the present invention will now be described with reference to the accompanying drawings to provide an understanding of the present invention. Here, FIG. 1 is a flow chart of a method of manufacturing a decorative material used for construction or construction using a used refractory brick as a raw material according to an embodiment of the present invention.

As shown in FIG. 1, first, a silica stone brick used for the inner wall of a coke oven, which is an example of a used refractory brick, is prepared, and if it is a size that cannot be transported, a crusher such as a breaker is used on site. It is crushed to a size that can be transported within 2 m. This is crushed with a pyrene 10 or the like into a size of about 250 mm. With this, the size can be put into the following jaw crusher.

Next, the roughly-used used refractory bricks are separated into an under portion and an over portion through a first grizzly shooter 11 in which rods are obliquely juxtaposed at relatively wide intervals. Then, the excess is crushed again by a pyrene or the like. The used refractory bricks for the under portion thus obtained are put into the next jaw crusher 12 and crushed. The used refractory bricks are crushed to about 20 to 120 mm by the jaw crusher 12, but a second grizzly groove is formed by arranging rods in a diagonal direction at relatively narrow intervals (about 120 mm pitch). Overshoot again through the shooter 13 and jaw crusher 12
Crushed by.

The under fraction of the jaw crusher 12 is classified by the sieving and classifying machine 14 according to the particle size. This classifier consists of a multi-stage vibrating screen, and is 20 mm under, 20-70 mm, 70-120 mm, 120 mm under.
Classified into particles with a particle size of over mm. Here, when the grain size exceeds 120 mm, the grizzly shooter 13 is used.
This is because the slender used refractory bricks may be partially mixed through the grizzly shooter 13, so that this is removed by a sieving and classifying machine including a screen. .

Next, of the classified material, the undersize of 20 mm is discarded, and the intermediate size of 20 to 70 mm and the large size of 70 to 120 mm are separately placed in the chamfering devices 15 and 16. Take the corner and round it. Here, the chamfering devices 15 and 16 are large-diameter rotary cylinders having a plurality of scraping blades inside, and are driven to rotate by a motor to lift the crushed bricks by the scraping blades and drop the bricks from above. In addition, the bricks are agitated and stirred internally to remove the corners of the bricks from each other. Here, it is also possible to provide a vibration source and rotate while vibrating the whole. Here, grain size 20-70m
m and the used refractory bricks having a grain size of 70 to 120 mm are separately put in the chamfering devices 15 and 16 to cause bricks of appropriate sizes to collide with each other and wear, thereby preventing the bricks from crushing each other as much as possible. It is designed so that only the outer corners can be removed.

When molten material such as brick or slag adheres to the crushed used refractory brick, this portion is fragile and is removed by the chamfering devices 15 and 16 to expose the brick. Then, the corners are removed and it becomes a rounded one. By applying it to the chamfering devices 15 and 16, the corners of the crushed used refractory brick are removed to form a round product. Here, sieving and classification are performed again by the classifier 17 to form a round product having a particle size of 20 to 60 mm, 60 to 90 mm and 90 to 120 mm to obtain a product.
In addition, 20 mm under can be used as concrete aggregate (sand), and can also be used as a soil improving material when it is strongly acidic or basic. This round material is used as a stone material for concrete to form a prism, and by cutting the prism, the color peculiar to bricks is exposed from the concrete surface, and becomes a decorative building or a decorative structure. Moreover, a natural feeling can be brought out by arranging this round material as a gravel instead of the cobblestone or by arranging it on the pond bottom, the aquarium bottom, or the river bottom.

In the above embodiments, silica bricks have been described as used refractory bricks, but the present invention is applicable to other types of bricks and ceramics such as alumina.
Further, in the above-mentioned embodiment, the classification has three stages, but it may be two stages or four or more stages. Further, when the crushing process by the jaw crusher cannot be sufficiently crushed, the jaw crusher may be provided in two stages.

[0013]

EFFECTS OF THE INVENTION The decorative material used for construction or construction using the used refractory bricks as claimed in claims 1 and 2 and the method for producing the same are, as is clear from the above description, prescribed used refractory bricks. Since it is crushed to a grain size and made into cobblestone, it can be used as a material for decorative construction or construction, and effective use of resources can be achieved. And
The melt adhering to the used refractory brick is removed in the process of crushing or grinding, so that it becomes a cobblestone only made of pure brick, and stable quality with no variation in hardness can be guaranteed.
