Description

Manufacturing method and machines of adiabatic panel for assembly-type building reusing abandoned EPS, abandoned rock-wool or abandoned glasswool etc .}

The present invention recycles prefabricated building insulation panels by recycling waste resins (general plastics, polyethylene resins, polystyrene resins, polypropylene resins, etc.), waste rock wool, waste glass fibers (waste glass wool), etc. as raw materials. It relates to a method and an apparatus for manufacturing and producing.

Insulation panels that have been used as prefabricated building materials include Styropole (EPS) sandwich panels, urethane panels, glass fiber (glass wool) panels, concrete PC panels, rock wool panels, and the following problems are pointed out. come.

① EPS sandwich panel and urethane panel are vulnerable to fire because the insulation uses foamed synthetic resin, there is a risk of toxic gas generated during combustion and suffocation of people, and it does not rot when disposed, causing environmental pollution. .

② Glass fiber (glass wool) panels depend on manual labor in manufacturing, and the manufacturing process is complicated, and the wool of insulation board structure is layered horizontally, so it is easy to crack horizontally, weak to external pressure, and weighs There are heavy drawbacks. In particular, glass fiber, a raw material of insulation, has been pointed out as a problem that causes cancer, and if the glass fiber panel is disposed of as waste, the environmental pollution and the risk to human body were very serious.

③ Concrete PC panel has a weak impact strength and heavy weight, which makes it difficult to transport and install.

④ Rock wool panels are weak to moisture, heavy, and have a rough feeling when they touch the skin, making transportation and construction difficult. In addition, lung rock wool does not rot and does not burn, and if left untreated, there is a risk of polluting the environment.

Nevertheless, buildings having a certain standard, such as apartments, villas, tenement houses, high-rise buildings, factory buildings, etc., have used non-combustible or flame-retardant panels as described above because they require standardization, assemblability, lightweighting, and flame retardancy.

However, since waste resin, waste rock wool and waste glass fiber embedded in these insulation panels were used only once and discarded as it was, they could not be recycled. Therefore, these waste resins, waste rock wool and waste glass fiber seriously caused environmental pollution problems. .

In order to solve these problems, the present invention seeks to find ways to prevent environmental pollution by collecting and recycling these waste materials into prefabricated building insulation materials.

Some of the prior arts deal with methods of manufacturing and producing insulation panels or sandwich panels containing the same by recycling waste rock wool or waste glass wool among these waste materials as raw materials.

However, the methods and devices proposed by the prior art regarding the production or production method of the insulation panel by using minerals such as lung rock wool or waste glass wool have many technical problems that are difficult to solve in reality.

In addition, when the insulation panel is manufactured using only mineral materials such as lung rock wool or waste glass wool, there is a disadvantage that the weight of the insulation panel is heavy, and because the manufacturing cost is high, the actual demand is small, so it was hardly utilized in the actual construction site.

The present invention solves the above problems, that is, a method or apparatus for manufacturing and producing a thermal insulation panel using minerals such as lung rock wool or waste glass wool, and solves technical problems that the prior arts have not practically solved. In the case of manufacturing insulation panels using only minerals, the insulation panels are heavy and expensive to manufacture.

That is, the present invention relates to a method and apparatus for manufacturing and producing a prefabricated building insulation panel using waste styropol, waste resin, waste rock wool, waste glass fiber, etc., which can be mass-produced by an automated production process, It is intended to manufacture and produce prefabricated building insulation panels that are flame-retardant, do not emit toxic gases, are more durable than existing insulation panels, have excellent waterproofness, insulation and sound insulation, and are inexpensive.

The prefabricated building insulation panels manufactured and produced by recycling these waste materials as raw materials by the manufacturing and production method provided by the present invention are more robust, cheaper, and more waterproof, soundproof, and thermally insulating than conventional insulation panels. It is flame retardant and safe to fire. Therefore, it is possible to manufacture a prefabricated building sandwich panel having excellent performance by using the insulation panel produced and produced by the method according to the present invention.

The present invention is based on the insulation panel manufacturing apparatus shown in FIG.

An automated process of manufacturing and producing the insulation panels shown in FIG. 3 is possible.

The production and production apparatus of the present invention is equipped with a hopper (1) into which raw materials are introduced from the upper part, and a compressor (4) for attaching a compressor (7) for blowing strong air pressure into the air inlet and rotating by a motor (5). and the crusher (2), two pairs of which are attached to the rotating shaft, and a pipe for the transport of the second pair that is transferred to the mixer by the pulverized raw material in a strong air pressure (8) and valve (9), for transport of the two pairs The connecting pipe 10 and the valve 9 connecting the pipes and the motor 16 are rotated and the screw 14 is rotated and vaporized from the adhesive injector 13 and the liquid nitrogen container 14 at the top. Nitrogen gas inlet is attached to allow nitrogen gas to be introduced, and two pairs of mixers 11 surrounded by the cooling device 12 and the mixed raw material (semi-finished product) in the state of the gel are made of strong nitrogen gas. Transferred to molding and hardening line by pressure To the conveying pipe (17), molding and curing line configuration, the conveyor belt 21 that is rotated by a motor 22, also runs in an up and down by a motor 20 as a part of the molding and curing line the mold or It consists of a top plate 19 to which a die is attached , and a cutting machine (not shown) in which the blade is made of diamond bits.

Here, the molding and curing line, which is composed of a conveyor belt 21 rotated by the motor 22 and an upper plate 19 which is operated up and down by the motor 20 and is attached to a mold or a wood, is formed in a gel state. The semi-finished product conveyed can be replaced by a closed mold 23 that is molded and cured into a required shape.

The automated process for manufacturing and producing the insulation panel using the above devices is as follows.

Raw materials such as waste resin, waste rock wool and waste glass fiber are introduced into the grinder 2 through the hopper 1, and then the grinding blade 4 attached to the rotary shaft 3 in the center of the grinder is connected to the motor 5. The raw material is crushed by rotating at a high speed by using.

The raw material is crushed by the grinding blade 4 which is rotated at a high speed by the motor 5 inside the grinder 2 and falls downward.

The grinding blade 4 is attached to the central shaft inside the grinder 2, and rotates together when the central shaft is rotated by the motor 5 to grind and mix the raw materials introduced into the hopper 1. Done.

The finely crushed and mixed raw materials in the grinder 2 are transferred to the mixer 11 using a strong air pressure.

In the mixer 11, the adhesive is sprayed and injected using the adhesive spraying device 13, while the screw 15 is rotated at a low speed using the motor 16, and the raw material (already broken) and the adhesive sprayed Are mixed evenly.

An adhesive means here an adhesive of components, such as a water-soluble adhesive or a urethane, an epoxy, a phenol.

Through such a mixing process, the crushed raw material and the adhesive are mixed with each other to form a gel semi-finished product.

And the semi-finished product of the gel (gel) is pushed downward while mixing the screw 15 is rotated by the motor 16 in the mixer (11).

Since a large amount of heat is generated due to the exothermic reaction during the mixing process, the cooling device 12 surrounding the mixer prevents the temperature from increasing and also delays the time for the gel semi-finished product to harden (cure). Will be done.

The semi-finished product in the gel state, which is mixed in the mixer 11 and pushed out downward, is transferred to the forming and curing line 18 using the pressure of strong incombustible nitrogen gas.

The reason why non-combustible nitrogen gas is used instead of general air is that, when general air is used, oxygen in the air reacts with the adhesive and there is a risk of curing the semi-finished product in a gel state. That is, unlike the transfer process of 2., the semi-finished product in the gel state is pushed out by using the strong pressure of the incombustible nitrogen gas evaporated from the container 14 filled with nitrogen in the liquid state.

In the process of performing the processes of the above 1.-4, the grinder 2 and the mixer 11 are provided in parallel, respectively, as shown in FIG. And in the process of conveying through the conveying pipe 8 from the grinder to the mixer, these conveying pipes 8 are connected to each other through the intermediate connecting pipe 10 and the valve (9).

The reason why the two grinders and the mixers are installed in parallel and connected to each other through the intermediate connecting pipes is that the other grinder 2 or the mixer 11 is stopped even if operation is stopped due to necessity of cleaning or the like. By using a mixer instead, the entire manufacturing production line in progress can be operated without interruption.

The molding and curing process of the semi-finished product in gel state can be selected from the following two methods.

end. Molding or hardening by tapping with a mold or a wooden die: The semi-finished product transferred to the molding and hardening line 18 is attached to the line upper plate 19 by using hydraulic pressure or pneumatic while being conveyed through the conveyor belt 21 or It is beaten with a wooden mold and molded and cured with a prefabricated building insulation of the required shape.

B. Method of forming and curing by putting in a mold and foaming: The semi-finished product transferred to a gel is placed in a closed mold 23 and foamed to be molded and cured.

During the above process, that is, in the process of tapping and curing the semi-finished product transferred to gel state by using hydraulic or pneumatic pressure, it is transferred according to mold or wood of tapping line plate or gel state. In the process of forming and curing the semi-finished product in a sealed state, it is molded and cured into a required shape according to the shape of the mold to be sealed (Examples of Fig. 3-31, 32, 33, 34, 35), and curing. Insulation panel products are used to be automatically cut to the required size by using a cutting machine (not shown) consisting of diamond bits in the cutting process.

In addition, if necessary, the panel may be formed with a wire passing tube to pass the wire.

That is, the present invention is ① grinding process of crushing waste resin, waste rock wool, waste glass fiber (waste glass wool) in the crusher, ② process of transferring these finely crushed raw materials into the mixer using strong air pressure, ③ these A process of mixing the transferred raw materials with an adhesive in a mixer equipped with a cooling device to make a semi-finished product in gel state. ④ Transfer these semi-finished products to a molding hardening line by using strong incombustible nitrogen gas pressure. In the molding and curing line, the semi-finished product transported in the gel state is struck with a mold or a wooden mold attached to the upper plate using hydraulic or pneumatic lines, or the semi-finished product transported in a gel state is foamed by placing in a closed mold and foaming. Process of molding and curing to the required shape by hardening, ⑥ It is done by doing.

Hereinafter, embodiments of the present invention will be described for each process.

1. Crushing process of raw materials

The raw materials are introduced into the grinder 2 through the hopper 1, and then the grinding blade 4 attached to the rotary shaft 3 at the center of the grinder is rotated at high speed using the motor 5 to crush the raw materials. At this time, the size of the finely divided raw material, if too small or too large, so that the molding and curing process is not smooth, so as to be 0.5 centimeter to 5 centimeters.

Here, the raw material refers to waste resin, waste rock wool, waste glass fiber, and the like. Styropol and urethane are the most representative waste resins, but all other resins such as polyethylene resin, polystyrene resin, and polypropylene resin may be used.

According to the experiment, the mixing ratio of raw materials should be 92: 8 (by weight%) or waste resin and waste glass wool (92%), respectively (by weight%). However, you may change a ratio as needed.

The raw material is crushed by the grinding blade 4 which is rotated at a high speed by the motor 5 inside the grinder 2 and falls downward.

The grinding blade 4 is attached to the central shaft inside the grinder 2, and rotates together when the central shaft is rotated by the motor 5 to grind and mix the raw materials introduced into the hopper 1. Done.

2. Transfer process of crushed raw materials

The finely crushed and mixed raw materials in the grinder 2 are transferred to the mixer 11 using a strong air pressure.

The air is injected into the compressor 7, but if the air pressure is too weak, the feed rate is slow, and if the air pressure is too strong, the mixing process of the raw material and the adhesive causes a problem, so it is preferable to set it to 4 kg / cm 2 to 7 kg / cm 2.

3. Mixing process of raw materials and adhesive

In the mixer 11, the adhesive is sprayed and injected using the adhesive spraying device 13, while the screw 15 is rotated at a low speed using the motor 16, and the raw material (already broken) and the adhesive sprayed Mix evenly.

An adhesive means here an adhesive of components, such as a water-soluble adhesive or a urethane, an epoxy, a phenol.

The mixing ratio of the raw materials (① waste resin + waste rock wool or ② waste resin + waste glass cotton) that have been crushed and transported is 96: 4 because the mixture is entangled firmly if too much glue is used, and the adhesive strength is weakened too little. Ideally (based on weight%), this ratio may vary depending on the application.

Through such a mixing process, the crushed raw material and the adhesive are mixed with each other to form a gel semi-finished product.

And the semi-finished product of the gel (gel) is pushed downward while mixing the screw 15 is rotated by the motor 16 in the mixer (11).

Since a large amount of heat is generated due to the exothermic reaction during the mixing process, the cooling device 12 surrounding the mixer prevents the temperature from increasing and also delays the time for the gel semi-finished product to harden (cure). Will be done.

4. Transfer process of semi-finished product in gel state

The semi-finished product in the gel state, which is mixed in the mixer 11 and pushed out downward, is transferred to the forming and curing line 18 using the pressure of strong incombustible nitrogen gas.

At this time, the pressure of the nitrogen gas is preferably set to 0.1 kg / cm 2 to 2 kg / cm 2 in accordance with the working speed of the molding and curing line.

The reason why non-combustible nitrogen gas is used instead of general air is that, when general air is used, oxygen in the air reacts with the adhesive and there is a risk of curing the semi-finished product in a gel state. That is, unlike the transfer process of 2., the semi-finished product in the gel state is pushed out by using the strong pressure of the incombustible nitrogen gas evaporated from the container 14 filled with nitrogen in the liquid state.

In the process of performing the processes of the above 1.-4, the grinder 2 and the mixer 11 are provided in parallel, respectively, as shown in FIG. And in the process of conveying through the conveying pipe 8 from the grinder to the mixer, these conveying pipes 8 are connected to each other through the intermediate connecting pipe 10 and the valve (9).

The reason why the two grinders and the mixers are installed in parallel and connected to each other through the intermediate connecting pipes is that the other grinder 2 or the mixer 11 is stopped even if operation is stopped due to necessity of cleaning or the like. By using a mixer instead, the entire manufacturing production line in progress can be operated without interruption.

5. Molding and Curing Process

The molding and curing process can be selected from two methods.

end. Molding and hardening method by tapping with mold or wood attached to upper part of molding and hardening line

The semi-finished product transferred to the forming and curing line 18 is knocked with a mold or wood attached to the line upper plate 19 using hydraulic or pneumatic pressure while being transported through the conveyor belt 21 to be formed into a prefabricated building insulation of a required shape. · Harden.

At this time, the temperature in the molding and curing line is preferably maintained in a state of 20 to 40 degrees Celsius in consideration of the state of the semi-finished product in the gel state.

B. Forming and curing by foaming in mold

The semi-finished product, which has been transferred in a gel state, is placed in a closed mold 23 and foamed to be molded and cured.

6. Cutting process

The cutting machine automatically cuts to the required size using a sharing machine (not shown), which is composed of diamond bits.

Through the manufacturing and production process as described above, the molded and cured insulation panels can be assembled with sandwich panels or internal partitions for building as required (could be combined with any exterior materials such as iron plate, gypsum board, balmite, MDF, HDF, etc.). It can be used as a material, and various panels can be manufactured directly according to the use, so it can be variously used as a substitute for concrete PC panels, soundproof wall panels, roof panels, and ceiling materials.

According to the present invention, waste resin, waste rock wool, waste glass wool, etc., which are generated from the process of producing building materials using resin, rock wool, glass wool, etc. as raw materials can be recycled, resulting in cost reduction and environmental protection. In addition, it is possible to produce a variety of products by mixing waste resin and lung rock wool or waste glass wool in an appropriate amount ratio.

In addition, the present invention can produce a solid and light non-flammable or flame-retardant insulation panel, it is possible to supply the product at low cost because it can be mass-produced by an automated process, in particular without depending on the manual work.
