Description

Yellow ocher brick and production method therefore and apparatus for molding yellow ocher brick

The present invention relates to an ocher brick used as an interior and exterior material of a building, a method for manufacturing the same, and a molding apparatus, and more specifically, a ball formed in a molding process and a margin angle of each corner even when extrusion is performed at high pressure using only pure ocher. By preventing internal cracking and shrinkage and maintaining a uniform compressive strength as well as a separate drying process does not require a separate drying process, it is related to a loess brick and a manufacturing method and a molding apparatus which can be palletized and constructed immediately.

In general, loess is widely regarded as a natural friendly material because of its excellent thermal insulation, insect repellent and antibacterial effect as well as thermal insulation, insect repellent and antibacterial effect, which are beneficial to human body. Coming out.

The building materials using loess are mainly bricks used as interior and exterior materials of buildings, and in addition, they are manufactured in various forms such as wall materials such as blocks and panels, floor materials such as temperature panels, and ceiling materials.

However, despite the fact that yellow soil has a variety of natural friendly functions that are beneficial to the human body, the use of loess itself is a problem because of its high compressive strength, internal cracking and shrinkage. Various manufacturing methods have been devised for this purpose.

Looking at the manufacturing method of building materials using conventional loess, in order to prevent the compressive strength and shrinkage, which are defects of the loess, such as manufacturing conventional cement bricks, various kinds of binders such as high molecular compounds, crests, gravel, sand, etc. The wet-drying method of mixing and kneading with water and drying is mainly used, and the methods of baking building materials, such as press-molded bricks, at a predetermined temperature are mainly used.

And other than that, the loess bricks are kneaded with wormwood or pine needles in the loess, and intersected horizontally and vertically with each other in the brick body dried by a predetermined time and dried by a cold air to prevent the strength and shrinkage of the bricks. It is intervened in No. 99-0021994, which is interposed in No. 002220, and formed by putting ocher soil and gravel into the inside using brick net, and integrally forming a ceramic layer in the ocher brick. A brick is published in Korean Utility Model Publication No. 94-24415.

Therefore, the building materials manufactured in the prior art are mainly manufactured by a wet drying method, which requires a separate drying time and a drying place after molding, and thus cannot be mass produced. In particular, in order to improve the compressive strength and the shrinkage rate, a separate binder is added Although the increase in the manufacturing process according to the required, in particular because the brick is filled inside the brick due to the nature of the ocher had a manufacturing defect that is difficult to maintain the strength due to shrinkage or cracking during use.

The present invention is to solve the various defects of the ocher bricks used as such conventional building materials, the object of the present invention is a high compression molding using only pure ocher, but the ball and the margin angle of each corner formed in the brick during molding It prevents internal cracking due to shrinkage by extruding air during extrusion, and evenly delivers high pressure evenly to the whole brick including corners when extruding to maintain uniform strength and mass production without drying. It is to provide an ocher brick that can be used immediately after production, a manufacturing method thereof, and a molding apparatus.

Compression molding to a predetermined volume so as to be uniformly delivered to maintain uniform strength; And taking out the completed bricks from the molding machine 18 to the conveying conveyor 46.

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

The manufacturing process of the ocher brick according to the present invention includes the steps of removing foreign substances of the collected ocher and pulverizing and transporting them into particulates, injecting appropriately the ochers pulverized and transported into particulates into the molding machine, compressing the ocher introduced into the molding machine to a predetermined volume. Consisting of the forming step and the final take-out step, with reference to Figures 1 and 4 will be described in more detail step by step the manufacturing process of the ocher brick according to the present invention.

Grinding step

The ocher from which various foreign matters are removed is pulverized several times in the stirring tank 10 to a predetermined particle size, and the crushed ocher particles are transferred to the hopper 14 using one or more conveyors 12 connected to the stirring tank.

Here, the ocher is preferably used in the Hwasun region of Jeonnam, the size of the ocher particles to be pulverized in the stirring tank 10 is not particularly limited, considering the bonding strength or appearance of the finished ocher bricks appropriate particles It is most preferable to grind to a size (about 5 mm or less), and the grinding process may be carried out by repeating the design several times using a conveyor.

Dosage step

The ocher particles transported to the hopper 14 are not evenly mixed again by the stirrer 16 which is rotated by a motor (not shown), and at the same time, a suitable amount is formed so that only one brick is formed into the molding machine 18 communicating with the lower part at a time. As it is input, it is pre-operated to input a proper amount according to the rotation and stop operation of the stirrer 16, and if necessary, the input amount may be sensed by a separate sensor means.

Compression molding step

The ocher particles introduced into the molding machine 18 through the above steps are gradually compressed and formed into a predetermined volume by the pressure 150t of the high pressure cylinder 20 connected to the compressor C. It is compressed by the compression plate 22 of the cylinder 20 and subjected to the resistance of the concave forming piece 30 of the cylinder shaft 28, which has been previously entered into the molding machine 18 by a predetermined length, When the compressive force applied to the particles is equal to or higher than the predetermined pressure 150t, the cylinder shaft 28 is gradually pushed as shown in Fig. 2 around the cylinder 34 provided by the opening and closing plate 32 by the compressive force.

Therefore, the ocher particles are exerted more strongly as they are first compressed by being hit by the concave forming pieces 30 formed by the cylinder shaft 28 of the opening and closing plate 32 at the time of compression molding. As shown in the center of the ocher particles are embedded pin pin 24 of a predetermined length horizontally installed by the compression plate 22 and at the same time both ends of the compression plate 22 and the opening and closing plate 32 of the coaxial The recessed shaping | molding pieces 26 and 30 each formed in the cylinder shaft 28 are lodged by predetermined depth.

On the other hand, the compressed ocher particles are centered at the time of compression by each of the concave molding pieces 26 and 30 in the molding machine 18, so that a stable operation is performed without flow.

In addition, the ocher particles compressed in the molding machine 18 are formed in each corner of the inner corner of the molding machine 18 having a square shape as shown in Figure 3 and the compression plate 22 and the opening and closing plate 32 respectively formed When the high-pressure cylinder 20 is compressed by the pieces 18a, 22a, and 32a, the compressive force is uniformly transmitted to the front and rear four sides, so that the compressive strength of the entire volume becomes uniform.

And the compression plate 20 and the opening and closing plate 32 of the high-pressure cylinder 18 is installed heating device 38, 40 controlled by the temperature sensor 36, respectively, ocher particles in a state containing water Is dried so as not to stick to the compression plate 20 and the opening and closing plate 32 in the compression process so that they are easily separated from them when taken out.

At this time, the heating temperature is preferably determined in consideration of various matters, such as the size of the brick to be manufactured or the degree of moisture content, but is controlled to maintain about 90 ℃ based on the case of manufacturing a brick size that meets the KS standards It is preferable.

Ejection stage

When the ocher particles are compressed at a high pressure in the above step, the opening and closing plate 32 which is blocking the outlet side of the molding machine 18 by the action of the cylinder 42 connected to the compressor C as shown in FIG. At the same time, the high pressure press 20 is further advanced and the compressed bricks are pushed onto the conveying conveyor 46. Then, the remaining parts except for both ends of the bricks in the dry state are formed. It slides out along the inner wall surface of 18 to be pulled out. When this operation is completed, the high pressure cylinder 20 is returned to its original position. At this time, when the high pressure cylinder 20 returns, the ball pin 24 installed as the compression plate 22 is naturally removed from the brick. By the operation, the air that is expanded in the volume during the compression process is discharged at the same time, which facilitates the circulation of the air, thereby preventing shrinkage during use and preventing cracks, thereby maintaining constant compressive strength and robustness at all times.

In the present invention, the brick manufactured through each of the above steps usually takes about 40 seconds, and as the molding operation is mechanically performed, continuous molding is possible, so that a large amount of production is possible, and is compressed at a high pressure by a cylinder. The constant strength (60 ㎏ / ㎠) according to it is maintained, by drying and compressing at high pressure using only pure ocher removed a certain amount of moisture without kneading the ocher with water, no separate drying process is required.

Figures 5a and 5b is a cross-sectional view of the ocher brick finally manufactured through each process according to the forming apparatus of Figure 1 as shown therein the brick body 1 is high extrusion molded using only loess material, the brick body A ball of a predetermined depth is formed in the center of the ball, and both side ends of the body 1 are hemispherical recesses 3 and 4 for carrying out a handle or a decorative function when carrying the ball coaxially with the ball 2. ) Are formed to face each other by a predetermined depth, and each corner of the brick body 1 has a margin angle 5.

Therefore, the above-mentioned bricks are desired to distribute the air through the regular ball (2) even during storage, and thus, compared to the brick in the closed state without the conventional ball, the brick is not retracted or deformed by shrinkage action and also prevents cracking and firmness. It is always maintained.

6 is a cross-sectional view showing another example of an ocher brick manufactured by remodeling a part of the molding apparatus of FIG. 1, which has only a difference in the presence or absence of recesses and recesses in the center as compared to FIG. In the molding apparatus of FIG. 1, the ball pin 24 and the concave part 26 of the compression plate 22 and the cylinder shaft 28 and the concave part 30 of the opening and closing plate 32 are removed. A relatively small volume of brick production such as 6 will be possible.

According to the present invention as described above, since only pure ocher is used, it is possible to produce beneficial effects such as far-infrared radiation, humidity control, etc., but compresses it into a high-pressure cylinder and forms by forming a margin angle with each ball and corner at the time of molding. It prevents cracking and shrinkage due to air discharge in the volume, and uniform strength due to even pressure delivery of media, so that it is not easily damaged. Dry drying without mixing water does not require a separate drying process. It is possible to manufacture bricks as possible, and also does not require a separate place due to drying it is economical and has the effect of enabling mass production according to continuous operation.
