Description

Semi-incombustible EPS board and manufacturing method thereof {Quasi-incombustible EPS board and method for manufacturing the same}

The present invention relates to a semi-non-combustible IPS board and a method for manufacturing the same, and more particularly, it can be manufactured by rapidly drying an IPS insulation panel to be installed on the exterior wall of a building, and when it is installed on the exterior wall of a building, the fire of the building It relates to a semi-non-combustible IPS board that can relatively more prevent and further improve the quality of a building, and a method for manufacturing the same.

In general, EPS Board refers to a product made in the form of a board by molding expanded polystyrene into a block type and then cutting it to a certain thickness. IPS board is made by processing expanded polystyrene and has good processability and very light properties.

Since the IPS board is manufactured by foaming the IPS bead, it has numerous micropores inside, which not only has excellent insulation properties, but can also effectively block noise and conversations coming from the outside, making it an optimal building It was considered as an insulator and noise-preventing material, and is actually used as an insulation material for buildings.

Since the IPS board has excellent thermal insulation properties, it is used in various ways in buildings. The easiest way is to attach an IPS board to the exterior wall of the building, and build bricks on the outside. However, since this method is only suitable for conventional brick-type buildings, there are certain limitations.

The so-called Dryvit construction method emerged to overcome these shortcomings and to use the IPS board more efficiently.

The dry bit construction method is generally carried out in the following way.

First, the PS board is lightly adhered to the exterior wall of the building, and fasteners are driven from the surface of the PS board to firmly fix the PS board to the exterior wall of the building. In this case, since the EPS board is firmly fixed to the building by means of fasteners, there is no fear that the EPS board is separated from the outer wall of the building or comes off no matter how long time elapses.

Then, in order to secure a bonding force between the EPS board and a different material, a mortar resin is applied to the surface of the PS board. The mortar resin mainly uses an acrylic adhesive mortar. However, since the surface of the PS board is very smooth and the material is a product made by foaming polystyrene, the bonding strength of the acrylic adhesive mortar applied to the surface of the polystyrene foam resin is weak.

Then, on the acrylic adhesive mortar layer, a wire mesh or glass mesh fiber is attached as a reinforcing material. The wire mesh serves to stably adhere and protect the PS board fixed therein, and to prevent the PS board from being partially depressed by an external force applied therein. On the other hand, the glass mesh fiber functions as a non-combustible material that prevents the EPS board from being exposed to a flame, and serves to protect the EPS board from external force. A fastener may be used to fix the wire mesh.

Then, on the wire mesh or glass mesh fiber as the reinforcing material, a plaster mortar as a finishing material is sprayed with a spray gun or the like, or a plaster paint is applied using a roller brush, etc. to form a coating film with various patterns and textures.

The dry bit method, which proceeds in this way, introduces an insulation system to the exterior wall of the building, and can finish the work relatively quickly, achieve insulation and sound insulation, and provide various colors and textures on the surface of the final finishing material. has the advantage of being able to express

However, in the dry-bit method, which is being carried out in the same way today, as briefly reviewed above, the surface of the IPS board used as an insulator and the adhesive mortar applied directly to the surface exert bonding force to each other at the initial stage of construction. However, the bonding force between them is showing a phenomenon that significantly decreases as time passes.

In order to understand this fact more clearly, a conventional insulation material PS board is presented in FIG. 12 .

12 shows a conventional EPS board formed of a board body 50 composed of EPS foam particles and a heat insulating layer 52 coated thereon.

The phenomenon in which the conventional EPS board shows weak bonding force on the surface of the building is that the surface of the PS board body 50 is very smooth, and the bonding strength between the polystyrene molecules that are the material of the PS board and the adhesive mortar molecules is Weakness can be said to be a fundamental problem, and as time goes by, this phenomenon becomes more severe.

In addition, as shown in Fig. 12, when the heat insulating layer 52 is formed on the PS board body 50, the heat insulating layer 52 and the adhesive mortar, which are also formed flat, are not well adhered to each other. it is getting worse.

Moreover, since the IPS board and the adhesive mortar installed by the dry-bit method exist on the outer wall of the building, they are essentially exposed almost as they are to the atmospheric environment. Atmospheric environment is repeatedly changing day and night every day, and summer and winter alternate every year. In addition, it is impossible to avoid the external force caused by typhoons that occur every summer and autumn, and the whole body has no choice but to endure the cold wave that blows in the middle of winter.

Due to such a temperature difference between day and night, a temperature difference between summer and winter, a cold wave that blows every winter, etc., cracks gradually occur between the surface of the EPS board body 50 or its heat insulating layer 52 and the adhesive mortar. This develops into a peeling phenomenon, which eventually appears as a disadvantage of the dry-bit method, and furthermore, leads to defects in the building by the dry-bit method.

Therefore, in the case of an IPS board product or heat insulating IPS board product used in the dry bit method, it is most urgent to solve the crack phenomenon between the IPS board body or its insulation layer and the adhesive mortar that occurs after construction. It is considered

On the other hand, in the case of manufacturing the conventional PS board, a large amount of inorganic insulating material is inevitably included in order to strengthen the thermal insulation performance, and a thermal insulation layer 52 is formed on the surface of the PS board, and the thermal insulation layer 52 is dried. Not only does it take a lot of time, but it also requires a large area to perform the drying process. This requires a wide and flat space site, which is directly related to the purchase of a large space site, which is acting as a cause of an increase in manufacturing cost.

As a result, it is considered that the technical task of the conventional IPS board is to realize high insulation performance, increase bonding strength with buildings, and achieve effective and efficient drying performance of the product.

As a prior art, the technology related to the construction method of the PS board is as follows.

Hereinafter, the present invention will be described more specifically and in detail.

Specific numerical values or specific examples provided in the present invention are preferred embodiments of the present invention, and are only for explaining the technical idea of the present invention in more detail, and it is clear that the present invention is not limited thereto. In addition, in the specification of the present invention, detailed description of parts that are known in the art and can be easily created by those of ordinary skill in the art will be omitted.

In addition, in the present invention, the meaning of 'suitable for dry bit' may be interpreted as 'suitable for dry bit products' or 'suitable for dry bit construction method'.

The present invention provides a semi-non-combustible PS board 200 suitable as an insulating non-combustible material to be constructed in a building. In the specification of the present invention, the EPS board may be abbreviated as "EPS board" if necessary.

1 is a conceptual diagram schematically showing a semi-non-combustible EPS board 200 according to the present invention.

Semi-non-combustible EPS board 200 according to the present invention, EPS (Expandable Polystylene) is composed of a board body 50 composed of expanded particles, and a heat insulating layer 52 formed on one or both surfaces of the board body 50 It is a further improvement of the product, and in particular, it is optimized as a product to be installed on the exterior wall of a building. Since the board body 50 composed of the EPS foam particles can be manufactured in a conventional manner, a detailed description thereof will be omitted.

In the present invention, the heat insulating layer 52 is further improved.

The heat insulating layer 52 is composed of inorganic non-combustible powder particles, and in the case of the finally finished EPS product, a semi-non-combustible heat insulating layer 80 is formed.

The inorganic nonflammable powder particles are expanded graphite, aluminum hydroxide, magnesium hydroxide, iron oxide, antimony oxide, zinc stannate, red, ammonium phosphate, ammonium polyphosphate, ammonium polyphosphate, molybdate, zirconium, melamine powder, melamine cyanurate, cyanide Any one or two or more selected from the group consisting of nuric acid, melamine phosphate, dimelamine phosphate, melamine pyrophosphate, and cement may be used.

The inorganic non-combustible powder particles finally form the semi-non-combustible insulating layer 80, which prevents the flame from moving to the inner body of the EPS board when a fire occurs in the building.

The inorganic nonflammable powder particles contain an acrylic component as a binder component and cellulose as a bonding aid. The acrylic component performs two functions, one of which contributes to forming the semi-non-combustible heat insulating layer 80 by bonding the inorganic non-combustible powder particles to each other, and the other is the It contributes to bonding the semi-incombustible heat insulating layer 80 and the mortar resin to each other. The mortar resin may be expressed as an adhesive mortar, and refers to a binder resin including a kind of mortar component used in the dry bit method.

On the other hand, the cellulose is usefully used to strongly bond the inorganic incombustible powder particles to each other. The cellulose is well known as a main component of pulp obtained by treating wood as cellulose, and has a very strong tension, and also contributes to bonding the semi-incombustible insulating layer 80 and the mortar resin to each other during dry bit construction.

The semi-incombustible insulating layer 80 includes a plurality of artificially formed intaglio depressions 82 . The plurality of intaglio depressions 82 are places where the surface of the semi-non-combustible heat insulating layer 80 is not smooth in a smooth state, but is regularly or irregularly recessed to make the surface of the semi-non-combustible heat insulating layer 80 smooth.

The intaglio recessed portion 82 has a shape like a small blind hole in the shape of a hole digging downward from the surface of the semi-non-combustible heat insulating layer 80 . The intaglio depression 82 may be formed in various ways. For example, it may be formed using a tool with a sharp tip such as an awl, or it may be formed by arranging a plurality of needle rods side by side on one horizontal rod, and manually or automatically pressing the needle rod, as shown in FIG. Likewise, a plurality of awls or chimbars may be formed on the outer circumferential surface of the roller 60 to automatically form in the process of moving the EPS board as shown in FIG. 5 .

Although the present invention exemplifies the intaglio depression 82 in the form of digging into the surface of the semi-non-combustible insulation layer 80, it is not necessarily limited thereto, and the surface of the semi-non-combustible insulation layer 80 is above the surface. It is also possible to form a plurality of embossed ridges (not shown) of a small protruding shape. In this case, after forming a plurality of depressions (not shown) on the outer peripheral surface of the roller 60 , the operation can be performed in the same manner as in FIG. 5 while rotating the roller 60 .

When the semi-non-combustible insulating layer 80 is used for the exterior wall of a building after it is finished as a product, an adhesive mortar is applied thereon, so that they come into direct contact with each other. In this case, the acrylic component as the binder component present in the semi-incombustible heat insulating layer 80 and the cellulose component as a bonding aid form a bonding relationship with the components of the adhesive mortar. This is because the adhesive mortar component is mainly composed of a cement component, but contains a fluidizing agent and a liquid acrylic emulsion component. It is preferable to use the dry bit method when it is installed on the outer wall of the building.

In other words, in the present invention, the function of the semi-non-combustible insulation layer 80 is not only formed to provide the insulation and non-combustibility of the EPS board, but the composition is specifically selected in consideration of the bonding strength with the adhesive mortar to be applied thereon. It means that it has been prepared.

In addition, the present invention expands the contact area with the adhesive mortar by forming a plurality of engraved depressions 82 or embossed ridges in the semi-non-combustible insulation layer 80, and through this, the semi-non-combustible insulation layer 80 ) and the bonding force between the adhesive mortar is further increased.

As a result, according to the present invention, by adding an acrylic component and a cellulose component to the semi-non-combustible insulation layer 80, the bonding relationship with the adhesive mortar is improved in a chemical way, and a plurality of It will be said that the bonding relationship with the adhesive mortar is improved in a physical way by forming an intaglio depression 82 or an embossed ridge of the mortar.

In addition, according to the present invention, the semi-non-combustible insulating layer 80 is automatically and continuously dried even in a small and limited space on the ground by the batch drying system 100, so that it can be commercialized in a much faster and more efficient manner than in the prior art.

It is preferable that the semi-non-combustible heat insulating layer 80 proceeds in a continuous drying method by the batch drying system 100 presented in the present invention. Since the continuous drying method by the batch drying system 100 is described in detail by the following manufacturing method, it will be referred to.

In addition, the present invention provides a method of manufacturing a semi-non-combustible PS board 200 suitable for the construction of an exterior wall of a building.

2 is a schematic block diagram of a method for manufacturing a semi-non-combustible PS board 200 according to the present invention.

According to the present invention, a method for manufacturing a semi-non-combustible EPS board includes the steps of preparing a non-combustible material solution and applying the non-combustible material solution to the surface of the EPS board (S210); forming a semi-non-combustible insulating layer 80 on the surface of the PS board (S220); a drying step (S230) of volatilizing and removing volatile components from the semi-incombustible heat insulating layer (80) formed on the surface of the PS board; contains

The present invention includes the step of preparing a non-combustible material solution and applying the non-combustible material solution to the surface of the EPS board (S210).

The step of applying the non-combustible material solution (S210) may be performed in a conventional manner, and the inventor or the patent applicant of the present invention has previously applied and received registration according to the prior art (Korean Patent Registration No. 10-2074766). It is better to do

For convenience of explanation, the present invention will briefly describe a method of applying a non-combustible material solution according to the Republic of Korea Patent Registration No. 10-2074766 (hereinafter abbreviated as 'prior registration patent').

In a conventional method, the incombustible material solution is put into a large container with a powdery incombustible material, stirred uniformly, and then applied to the surface of the PS board.

On the other hand, in the method of the prior patent registration, a powdery incombustible material is put into a large container to prepare a non-combustible material solution, the incombustible material raw material solution is transferred to the surface of the EPS board, and the non-combustible material raw material is transferred to the surface of the EPS board. This is done by distributing and applying the solution uniformly.

The method of the prior registered patent is briefly summarized as follows.

3 is a representative view showing a device used to apply a non-combustible material to the surface of the EPS board according to the prior registered patent. However, in FIG. 3, it should be noted that the device part for forming the intaglio depression 82 on the surface of the final EPS board is configured differently from the device of the prior patent registration.

First, the prior registered patent puts 10 to 35 parts by weight of water, 35 to 80 parts by weight of inorganic non-combustible material, 10 to 25 parts by weight of a binder, and 1 to 5 parts by weight of a dispersant in a large tank container 10, and these are stirred blades (13) is stirred slowly, and discharged to the outside through a plurality of outlets 114 .

At this time, water is an aqueous solution and functions as a solvent for the inorganic incombustible material, but should be dried and removed later. When it is 10 parts by weight or less based on the total weight, the dispersion state is not good, and when it is 35 parts by weight or more, there are too many solution components, so that even coating becomes difficult.

The inorganic non-combustible material is a powder or particulate inorganic material, preferably inorganic particles that do not burn even when exposed to a flame. The inorganic nonflammable material is expanded graphite, aluminum hydroxide, magnesium hydroxide, iron oxide, antimony oxide, zinc stannate, red, ammonium phosphate, ammonium polyphosphate, ammonium polyphosphate, molybdate, zirconium, melamine powder, melamine cyanurate, cyanuric acid , melamine phosphate, dimelamine phosphate, melamine pyrophosphate, and any one or two or more selected from the group consisting of cement may be used.

Among the components of the inorganic non-combustible material, the cement did not exist in the prior registered patent, but it was added in the present invention. The reason is considering that the main components of the mortar resin to be overlaid on the surface of the finished EPS board are cement and blast furnace slag. When the inorganic non-combustible material is less than 35 parts by weight, the coated thickness is too thin to provide flame retardancy, and when it is more than 80 parts by weight, it is difficult to transfer through the pipeline, and the dispersion state is also bad, so workability and product quality are adversely affected. drive crazy

The binder is a binder for bonding the inorganic non-combustible material to the surface of the EPS board product 50 . When the amount of the binder is 10 parts by weight or less, the strength for bonding the inorganic non-combustible materials to each other is weak, which is not preferable, and when the binder is more than 25 parts by weight, it becomes an obstacle to forming an even and flat thickness due to excessive bonding force. The binder should essentially contain an acrylic component and a cellulose component. Since the reason has been described in detail above, it will not be repeated here.

The dispersant is for evenly dispersing the inorganic nonflammable material in an aqueous solvent (water), and a surfactant may be representatively exemplified. When the dispersant is used in an amount of 1 part by weight or less, the dispersion state of the inorganic nonflammable material particles in the aqueous solution is not good, whereas when it is used in an amount of 5 parts by weight or more, the dispersion state is not better compared to the added weight.

The prior registered patent transfers the incombustible raw material from the large tank container 10 to the spraying device with no pump action, and at the same time continuously moves the EPS board product 50 on the transport device 70 in the horizontal direction. Then, the incombustible raw material is sprayed onto the surface of the EPS board product 50 by the spraying device 30 and supplied. The spray device 30 was independently developed by the patent applicant on the basis that the non-combustible raw material is an inorganic material, and the specific configuration and operation relationship thereof are described in detail in the prior registered patent, so this will be explained shall be omitted.

The present invention includes the step (S220) of forming a semi-non-combustible insulating layer 80 on the surface of the EPS board.

The step of forming the semi-non-combustible insulating layer 80 (S 220) is to spread the non-combustible raw material supplied on the surface of the EPS board product 50 in a flat and even manner, and then a plurality of needle rods are formed on the outer periphery of the roller. A plurality of intaglio depressions 82 are formed by the rollers 60 . This means that it is proceeding in two stages.

As a first step, when a non-combustible material is supplied on the surface of the EPS board product 50, it is spread out flat and evenly. It is preferable to use the scraper 40 for the planarization method of the incombustible raw material. The scraper 40 fills a portion where the non-combustible material is not well coated or non-uniformly applied, so that the non-combustible material spreads more evenly on the surface of the EPS board product 50 . The height of the scraper 40 is installed to be freely adjustable. After the flattening operation by the scraper 40 is finished, the flattening operation may be additionally performed by a spinning wheel (not shown). Since such a planarization operation is already known in detail by the prior registered patent, a detailed description thereof will also be omitted.

As a second step, when the planarization operation is completed on the surface of the EPS board product 50 , a plurality of intaglio depressions 82 are formed with respect to the semi-incombustible heat insulating layer 80 .

Since the function and shape of the plurality of intaglio depressions 82 have been described in detail above, a forming method thereof will be described herein.

In the case of manual operation, the intaglio depression 82 may be formed by using a tool with a sharp tip, such as an awl, or in the case of semi-automatic, a plurality of needle rods are arranged side by side on one horizontal rod, and the needle rod is manually installed. Alternatively, it may be formed by automatically pressing, and in the case of fully automatic, as in FIG. 4, a plurality of awls or needle rods are formed on the outer circumferential surface of the roller 60 to automatically form in the process of moving the EPS board as shown in FIG. You may. The present invention favors a fully automated approach.

Instead of forming the intaglio depression 82, it is possible to form an embossed ridge, and it should be noted that this has already been described in detail.

The present invention includes a drying step (S230) of volatilizing and removing volatile components from the semi-non-combustible insulating layer 80 formed on the surface of the EPS board.

Until today, there are many difficulties in drying the non-combustible material coated on the surface of the EPS board product 50 . It is necessary to volatilize the liquid solution component among the incombustible raw materials and obtain a finished product quickly, because there are problems in that it takes a lot of drying time and requires a wide and extensive drying workshop. As the thickness of the non-combustible raw material increases, flame retardancy or non-combustibility can be increased. On the other hand, if the thickness is thinned in order to shorten the drying time, cracks are easily generated and the quality of the product is lowered, and the disadvantage that essential flame retardant performance itself cannot be obtained is exposed. Resolving these contradictions as soon as possible is one of the most important reasons.

The present invention reveals that the problems that cannot be solved by the conventional drying method have been solved at once by mobilizing the following methods.

In the present invention, the drying step (S230) is carried out by the batch drying system (100).

6 shows that the EPS board product 50 enters the first floor of the batch drying system 100 and is dried to the fourth floor, and is discharged through the outlet on the fifth floor,

7 shows that the EPS board product 50 enters the first floor of the batch drying system 100, is dried to the third floor, and is discharged through the outlet on the fourth floor. However, while FIG. 6 is viewed from the rear, FIG. 7 is a perspective view viewed from the front.

On the other hand, FIG. 8A is a plan view of the batch drying system 100 of the present invention viewed from the top down, and FIG. 8B is an exploded state showing the batch drying system 100 of the present invention by dividing each layer and displaying their coupling relationship. It is a relationship diagram,

9 is a schematic front view showing the coupling relationship of each layer in a state in which the multi-layer batch drying system of the present invention is viewed from the front.

In the drying step (S 230) of the present invention, the EPS board product 50 enters the entrance of the batch drying system 100 and proceeds for a predetermined distance in parallel in one direction in the horizontal direction on a plane, and the end thereof The direction is changed by turning 180 degrees in a fan shape in a clockwise or counterclockwise direction, and proceeds in parallel by a predetermined distance in the direction opposite to the horizontal direction on a plane, and then clockwise or counterclockwise at the end The direction is changed by turning 180 degrees in a fan shape, and in the process, the heat insulation layer 80 of the EPS board product 50 is dried by high-temperature hot air, and the volatile component is blown to the outside and discharged. lose

When the batch drying system 100 is formed in a single layer, the EPS board product 50 proceeds in parallel for a predetermined distance in one direction in the horizontal direction on the same plane as in the beginning again, and the end The direction is changed by turning 180 degrees in a fan shape in a clockwise or counterclockwise direction, and proceeds in parallel for a predetermined distance in the direction opposite to the horizontal direction on a plane, and then clockwise or counterclockwise at the end The method of turning 180 degrees in a fan shape in the direction to change the direction is repeatedly performed several times, and in the process, the drying operation can be carried out with high-temperature hot air.

On the other hand, when the batch drying system 100 is formed of two or more layers and a plurality of multi-layers, the EPS board product 50 rotates 180 degrees at the opposite end of the horizontal direction in the first layer and at the same time, It rises to the second floor and goes up, and the work proceeds from the second floor in the same manner as in the first floor. That is, the EPS board product 50 proceeds in parallel by a predetermined distance in one direction in the horizontal direction on the second floor, and then turns 180 degrees in a fan shape in a clockwise or counterclockwise direction at the end portion. to change the direction, proceed in parallel for a predetermined distance in the direction opposite to the horizontal direction on the plane, and at the end of the end, turn 180 degrees in a clockwise or counterclockwise fan shape to change the direction, It will go up to the 3rd floor.

When the EPS board product 50 comes up to the third floor, it proceeds from the third floor again in the same manner as in the second floor, and goes up to the fourth floor while rotating in a fan shape at the opposite end in the horizontal direction, and this When the same operation is repeated and the final dry layer is reached, it is dried in the final dry layer and then discharged to the outside through the outlet.

As such, in the batch drying system 100, the EPS board product 50 moves by a predetermined distance in the horizontal direction and turns 180 while turning in a fan shape at the end portion thereof, and in the opposite direction to the horizontal direction. After moving by a predetermined distance, the direction is changed 180 degrees while turning again in a fan shape at the end, and in that state, it is connected in the same way as the original horizontal layer to perform a repeated operation, or at the same time as changing the 180 degree direction Since it is made in such a way that it ascends to the upper floor, the internal structure of each floor is very important. The internal structure of each layer is preferably operated by applying the structure of the first layer, which is the most basic, as it is.

The one-layer structure of the batch drying system 100 is well illustrated in FIG. 8A .

The batch drying system 100 includes a first roller assembly 110a that moves the EPS board product 50 by a predetermined distance from the inlet side of the left end to the right, and the EPS board product 50 in the right direction. The second roller assembly 110b, which turns 180 degrees while slowly turning from the right to the left in a fan shape at the end of the The third roller assembly 110c that moves by a predetermined distance and the EPS board product 50 are rotated 180 degrees from the left to the right in a fan shape at the end of the left direction while at the same time changing the direction in the n-layer. (n+1) includes a fourth roller assembly (110d) for moving inclined to the layer.

The first roller assembly 110a may be formed by combining a plurality of forward roller conveyor assemblies (A). In the forward roller conveyor assembly (A), a plurality of idle rollers (R) are coupled, and when the idle rollers (R) are idling on the spot in a clockwise or counterclockwise direction, on top of the idle rollers (R) It performs a function of moving the placed EPS board product 50 in one direction. The length in the horizontal direction of the first roller assembly 110a may be determined according to the number of the forward roller conveyor assemblies A coupled thereto.

As a result, the function of the first roller assembly 110a is to perform a function of moving the EPS board product 50 by a predetermined distance in one direction.

The second roller assembly 110b may be formed by combining a plurality of sector-shaped roller conveyor assemblies (B). In the sectoral direction roller conveyor assembly (B), a plurality of idle rollers (R) are also arranged and coupled in a sectoral shape, and when the idle rollers (R) are idling on the spot in a clockwise or counterclockwise direction, the While turning the EPS board product 50 placed on the idle rollers (R) in a fan shape, the direction is changed little by little. The number to which the sectoral direction roller conveyor assemblies (B) are coupled can be adjusted according to the direction change of 180 degrees as a whole.

As a result, the function of the second roller assembly 110b is to perform a function of turning the EPS board product 50 in a sectoral shape while turning it 180 degrees as a whole to convert it to the opposite direction.

The third roller assembly 110c may be formed by combining a plurality of reverse roller conveyor assemblies (C). The reverse roller conveyor assembly (C) has the same components as the forward roller conveyor assembly (A), operates in the same manner, except that it reverses its travel direction. In addition, the length in the horizontal direction of the third roller assembly 110c may be determined according to the number to which the reverse roller conveyor assemblies C are coupled.

As a result, the function of the third roller assembly 110c is to move the EPS board product 50 from one direction to the opposite direction by a predetermined distance.

The fourth roller assembly 110d may be formed by combining a plurality of sector-shaped upward roller conveyor assemblies (D). The sector upward roller conveyor assembly (D) is also coupled to a plurality of idle rollers (R) are arranged in a sector shape, when the idle rollers (R) are idling on the spot in a clockwise or counterclockwise direction, While turning the EPS board product 50 placed on the idle rollers (R) in a fan shape, the direction is changed little by little, and at the same time, the EPS board product 50 placed on the idling rollers (R) is slightly raised upward in an upward direction. This is that the sector-shaped roller conveyor assemblies (B) rotate in a sector on the same horizontal plane, whereas the sector-shaped upward roller conveyor assembly (D) rotates in a sector and rises little by little in the upward direction at the same time. . When a plurality of sectoral upward roller conveyor assemblies (D) are combined to complete the fourth roller assembly (110d), the fourth roller assembly (100d) is vertical as much as one layer of the batch drying system (100). form a distance.

As a result, the function of the fourth roller assembly 110d is to turn the EPS board product 50 in a fan shape while turning it 180 degrees as a whole to convert it in the opposite direction, and at the same time to move the EPS board product 50 from the lower layer. Rather than that, it performs the function of sending it up to the upper floor, which is one floor higher.

On the other hand, the batch drying system 100 is provided with a hot air means 120 for supplying hot air to remove volatile components including water from the EPS board product 50 moving therein and dry it, and the hot air A blowing means 130 for forcibly discharging to the outside is installed. Since the warm air means 120 and the air blower 130 are conventional, a detailed description thereof will be omitted.

In the two-layer structure of the batch drying system 100, the first roller assembly 110a of the second layer is coupled to the fourth roller assembly 110d of the first layer, and in the second layer, the first layer It has the same structure as the roller assemblies present in the .

In addition, the structure of the 3rd to 10th layers of the batch drying system 100 is also the same as the structure of the 2nd layer, and from the lower layer to the upper layer is the same by the fourth roller assemblies 110d. connected in a way.

In the present invention, it is preferable to proceed with the batch drying system 100 by combining a plurality of roller assemblies.

The drying step (S230),

One). It is carried out by the batch drying system 100,

2). The batch drying system 100 is, in the n-layer, the EPS board product 50 is dried while drawing an elliptical track on a plane, and a sector-shaped track from the n-layer to the (n+1) layer at one end part of the elliptical track. will rise to

3). The batch drying system 100 is performed within the range of 1 to 10 layers, and the letter n is a number representing each layer and means any one of the numbers 1 to 9,

4). The batch drying system 100 is technically characterized in that when the final drying layer is reached, the EPS board product 50 is discharged to the outlet to proceed.

The batch drying system 100 for performing the drying step (S230) may be performed in a single layer. In this case, however, considering the drying space or drying site for performing the drying process, it is preferable to install it in two or more floors and design it to 10 floors or less. Of course, installing more than 10 floors is not actively excluded, and considering the cost and efficiency of installation, it is better to set the appropriate level to 10 floors or less.

In a preferred embodiment, when the multi-layer batch drying system is installed in four or more layers, the drying step (S230) may be performed in the following manner.

The batch drying system 100, on the first floor, is dried in the process of moving the EPS board product 50 while drawing an elliptical orbit on a plane, and a sectoral track from the first floor to the second floor at one end of the elliptical track. will rise to

On the second floor, the EPS board product 50 is dried in the process of moving while drawing an elliptical track on a plane, and rises from the second floor to the third floor in a fan-shaped track at one end of the elliptical track,

On the third floor, the EPS board product 50 is dried in the process of moving while drawing an elliptical orbit on a plane, and rises from the third floor to the fourth floor in a fan-shaped track at one end of the elliptical track,

On the 4th floor, the EPS board product 50 is dried in the process of moving while drawing an elliptical orbit on a plane, and rises from the 4th floor to the 5th floor in a fan-shaped orbit at one end of the elliptical orbit,

The remaining layers are repeatedly dried in the same manner as above, and in the final drying layer, the EPS board product 50 is discharged to the outlet to complete the drying process.

In the present invention, in the batch drying system 100, a plurality of roller conveyor assemblies are combined, and the final shape in which the plurality of roller conveyor assemblies are combined forms an elliptical orbit, and is placed on the roller conveyor assembly. The EPS board is dried while moving the EPS board product 50 in one direction.

On the other hand, Figure 9 is a schematic front view showing the coupling relationship of each layer in a state in which the batch drying system 100 constituting a preferred embodiment of the present invention is viewed from the front,

Figure 10a is a conceptual diagram showing the configuration of the forward roller conveyor assembly with respect to part "A" constituting the preferred batch drying system 100 of the present invention, Figure 10b is a plan view of Figure 10a,

11A is a conceptual diagram showing the configuration of a sector-shaped roller conveyor assembly for part "B" constituting the preferred batch drying system 100 of the present invention, and FIG. 11B is a conceptual diagram showing another embodiment of FIG. 11A.

In the present invention, the forward roller conveyor assembly (A) includes a plurality of idle rollers (R) arranged in a plane.

The idle roller (R) is formed to be long in the shape of a rod, and idles around its central axis (X). The idle rollers (R) are supported by supports (S) on both sides that exist in both directions, respectively, and are fixed at their positions. In addition, the idle rollers (R) are idle by the rotating shaft (X) constituting its central axis. In addition, the idle rollers (R) form a set of assembly units by the chain belt (V), and when the chain belt (V) moves in one direction, the idle rollers (R) are placed on one side will rotate in the direction The chain belt (V) is chain-coupled to a motor (M) that causes rotational motion by external electric energy, so that the chain belt (V) is moved in one direction by the rotational motion of the motor (M). are connected This coupling relationship is well illustrated by FIGS. 10A and 10B.

The forward roller conveyor assembly (A) is operated as follows.

When the EPS board product 50 from the outside enters through the inlet of the batch drying system 100 and is placed on the forward roller conveyor assembly (A), electric energy is supplied from the outside to operate the motor (M). When the motor (M) generates rotational power, the chain belt (V) starts to move in one direction by receiving the rotational power, and when the chain belt (V) moves in one direction, the chain belt ( A plurality of idle rollers (R) hanging on V) will idle clockwise or counterclockwise on the spot. Therefore, the EPS board product 50 to be dried is horizontally moved in one direction from above the idle rollers (R).

In the present invention, the sector direction roller conveyor assembly (B) is configured by arranging a plurality of idle rollers (R) in a sector shape on a plane.

The sectoral direction roller conveyor assembly (B) forms a space spaced apart from each other while forming a sectoral shape with the supporters (S) on both sides of the concentric circle as the center. This is embodied in that the inner support (S1) constituting the inner side of the concentric circle is formed shorter than the outer support member (S2) forming the outer side of the concentric circle. In addition, a plurality of idle rollers (R1) are arranged narrowly in the inner direction of the fan-shaped concentric circle between the both supports (S1) and (S2), while being arranged in a shape that opens toward the outer direction of the fan-shaped concentric circle. On the other hand, the chain belt (V) causes the idle rollers (R1) to idle simultaneously in one direction, and the motor (M) causes rotational motion by external electric energy to move the chain belt (V) in one direction. . This coupling relationship is well illustrated by Fig. 11a.

In the sectoral direction roller conveyor assembly (B), in that the supports (S1) and (S2) on both sides are rotating while forming a sectoral concentric circle with each other, the supports (S) on both sides of the forward roller conveyor assembly (A) are mutually It is different from the fact that they are arranged parallel to each other while forming the same spacing.

In addition, in the sectoral direction roller conveyor assembly (B), the plurality of idle rollers (R1) are arranged narrowly inside a sectoral concentric circle with each other between the supports (S1) and (S2), and are arranged relatively wide on the outside of the sectoral concentric circle. In that it is, the forward roller conveyor assembly (A) is different from that a plurality of idle rollers (R) are arranged while forming the same distance from each other between both supports (S).

The sectoral direction roller conveyor assembly (B) is operated as follows.

When the EPS board product 50 moves upward of the sector-shaped roller conveyor assembly (B), the motor (M) is operated by an automatic control system. When the motor (M) generates rotational power, the chain belt (V) starts to move in one direction by receiving the rotational power, and when the chain belt (V) moves in one direction, the chain belt (V) ), a plurality of idle rollers (R1) hanging on the clockwise or counterclockwise rotation on the spot. At this time, the EPS board product 50 placed above the idle rollers (R1) moves in one direction and receives a slight force inward of the fan shape while moving in one direction, and performs a flat curved motion in the process of moving.

In the present invention, as a preferred embodiment, the sector-shaped roller conveyor assembly (B) is further improved. This is to enable the rotational movement of the EPS board product 50 to proceed smoothly, and FIG. 11B shows this embodiment well.

The improved sector-shaped roller conveyor assembly (B) uses the improved idling roller (R2) instead of using the conventional idle rollers (R) (R1) arranged in the sector-shaped direction. The improved idle roller (R2), the diameter of the body portion corresponding to the outside of the sector is formed larger than the diameter of the body portion corresponding to the inside of the sector. In this case, when the idle roller R2 is idle by the motor M and the chain belt V, the rotating distance of the body rotating from the outside is compared to the rotating distance of the body rotating from the inside , resulting in more lengths or more rotational distances. This means that even when the same idle roller (R2) rotates to the same degree, a larger rotational distance is formed on the outside, and a smaller rotational distance is formed on the inside. Other components are the same as described above.

The improved sector-shaped roller conveyor assembly (B) is operated as follows.

When the EPS board product 50 moves upward of the improved sector-shaped roller conveyor assembly B, the motor M is operated by an automatic control system. When the motor (M) generates rotational power, the chain belt (V) is moved in one direction, and a plurality of idle rollers (R2) hung on the chain belt (V) are clockwise or counterclockwise on the spot. will rotate in a clockwise direction. At this time, the idling rollers R2 have a longer moving distance on the outside of the sector, and a shorter moving distance on the inside of the sector. Accordingly, the EPS board product 50 placed on the plurality of idle rollers (R) naturally moves more on the outside of the sectoral shape, while moving less on the inside of the sector, due to this, The EPS board product 50 is not pushed outward, but naturally moves while rotating in a fan shape.

The present invention includes a plurality of reverse roller conveyor assemblies (C) in the batch drying system (100).

The technical configuration of the reverse roller conveyor assembly (C) is the same as that of the forward roller conveyor assembly (A), except that the arrangement is in the opposite direction.

Therefore, the technical configuration and the operating relationship of the reverse roller conveyor assembly (C) are the same as described above, but the moving direction is different, and thus detailed description is omitted.

The present invention includes a plurality of sector-shaped upward roller conveyor assemblies (D) in the batch drying system (100).

The sector-shaped upward roller conveyor assembly (D) is the same as the sector-shaped roller conveyor assembly (B) described above, except that each of the idle rollers (R1) is arranged while gradually ascending in the upward direction little by little. there is only

The fan-shaped upward roller conveyor assembly (D) is operated as follows.

When the EPS board product 50 moves upward of the fan-shaped upward roller conveyor assembly D, the motor M is operated by an automatic control system. When the motor (M) generates rotational power, the chain belt (V) is moved in one direction, and a plurality of idle rollers (R1) and (R2) hung on the chain belt (V) are rotated on the spot. idling in the clockwise or counterclockwise direction. At this time, the EPS board product 50 is gradually rotated while drawing a sector by the idle rollers R1 and R2.

However, compared to the idle rollers on which the EPS board product 50 was placed, the next placed idle rollers are arranged higher, so that the EPS board product 50 naturally upwards in the process of moving in a fan shape. It moves as it rises, and finally, it moves from the n-floor that has moved in the plane so far to the next (n+1) floor.

In other words, when each of the idle rollers R1 and R2 is idle by the motor M and the chain belt V, the EPS board product 50 placed thereon rises upward little by little. It rotates in a fan shape, and finally changes its direction by about 180 degrees. At this time, in each n-layer, the EPS board product 50 is raised to a higher (n+1) layer than that.

As a result, the batch drying system 100 proposed in the present invention forms the first roller assembly 110a by combining a plurality of forward roller conveyor assemblies A in each layer as described above, and a plurality of sectoral direction roller conveyor assemblies (B) is combined to form a second roller assembly (110b), a plurality of reverse roller conveyor assemblies (C) are combined to form a third roller assembly (110c), and a plurality of sector-shaped upward roller conveyor assemblies (D) ) are combined to form a fourth roller assembly 110d, and they are combined as a whole to form an associated drying layer.

The related drying layer may constitute a single flat elliptical orbital batch drying system, or a multi-layered batch drying system consisting of 2 to 10 layers.

The accompanying drawings 6 to 9 show the technical configuration of the batch drying system 100 in various aspects and their coupling relationship.

The present invention, each roller conveyor assembly as a preferred embodiment 4 to 5 idle rollers (R) (R1) (R2), two side supports (S) (S1) (S2) and two chain belts (V) and one motor (M) are basically included. Of course, these components can be formed by varying the number, and each component can be configured differently or by improving it.

In addition, although 4 to 5 of the roller conveyor assemblies have been selected and described, this is presented in the form of a preferred embodiment thereof, and it will be obvious that the assembly is not limited thereto.

In the present invention, it is most preferable to combine the roller conveyor assemblies with each other to form a batch drying system 100, and then to dry them as described above.

In the present invention, the EPS board product 50 on which the semi-non-combustible insulation layer 80 is formed is put into the inlet of the batch drying system 100, dried continuously while drawing an elliptical orbit on the first floor, and ascended to the second floor, , continuously dried while drawing an elliptical orbit on the 2nd floor and raised to the 3rd floor, continuously dried while drawing an elliptical orbit on the 3rd floor and raised to the 4th floor, dried continuously while drawing an elliptical orbit on the 4th floor 5 After the drying step is performed in the same manner as above, the drying process is performed by discharging the EPS board to the outside in the final drying layer.

Hereinafter, the drying step (S 230) of the present invention will be described in detail for each layer.
