Therefore, these terms or words should be interpreted as meanings and concepts corresponding to the technical spirit of the present invention. Therefore, the embodiments described in the specification and the drawings shown in the drawings are only one of the most preferred embodiments of the present invention and do not represent all of the technical ideas of the present invention, various modifications that can be replaced at the time of the present application It should be understood that there may be equivalents and variations.

As described above, to compensate for the shortcomings of concrete products, MSPC products are manufactured by mixing SPC (Sulfur Polymer Cement), such as sulfur polymer, in concrete at a predetermined ratio in a concrete composition composed of coarse aggregate, fine aggregate, and filler. A method was developed. In the above method, first, SPC (Sulfur Polymer Cement), such as sulfur polymer, is mixed with the concrete composition at a predetermined ratio to mix the modified Sulfur Polymer Concrete (MSPC) composition.SPC, such as sulfur polymer, has a temperature of about 100 to 160 ° In, it is preferably mixed with the concrete composition at a temperature of 130 ~ 140 ℃ to mix the MSPC composition.

1 is a perspective view of an MSPC composition mixing apparatus 100 according to a preferred embodiment of the present invention.

Referring to the drawings, MSPC composition mixing apparatus 100 according to the present invention is a hopper 10 for receiving aggregates, a meter 20 connected to the hopper 10 to drop a predetermined amount of aggregate, and SPC (in aggregate) A mixer 30 is added to mix the modified sulfur polymer concrete (MSPC) composition by adding sulfur polymer cement (Sulfur Polymer Cement).

The hopper 10 is made of a size suitable for receiving aggregate. Hopper 10 may have a variety of forms.

A predetermined number of partition walls 11 are installed in the hopper 10. 1 shows a hopper 10 partitioned into two receiving spaces A and B, the hopper 10 may be partitioned into various numbers. The number of separation walls 11 is determined according to the number of aggregates or the size of aggregates accommodated in the hopper 10. In other words, aggregates of different sizes are accommodated in the accommodation spaces A and B partitioned by the dividing wall 11.

Preferably, the dividing wall 11 has a height lower than that of the outer wall 13 of the hopper 10. This will be described later.

The screen 12 is installed on the hopper 10. Preferably, the screen 12 is installed on the top of the separation wall 11 and the top of the outer wall 13 of the hopper 10, the separation wall 11 has a height lower than the outer wall 13 of the hopper 10. Since the screen 12 is inclined downward toward the dividing wall (11). Although not shown in the figure, an aggregate supply part for supplying aggregate is installed on the upper side of the screen 12 to drop the aggregate into the screen 12. Among the dropped aggregates, aggregates smaller than the holes of the screen 12 penetrate the screen 12 and are accommodated in the accommodation space A under the screen 12. Aggregates larger than the holes of the screen 12 are screened. It does not penetrate 12 and rolls down along the inclination of the screen 12, and is accommodated in another accommodation space B. As shown in FIG.

By using the same principle, by installing a screen 12 having holes of different sizes at the upper end of each receiving space (A) (B) to accommodate aggregates of different sizes in different receiving space (A) (B) can do.

Preferably, the aggregate is heated to 140 ~ 150 ℃ in advance before being dropped into the hopper 10. The heat-drying of the aggregate in advance is because if the aggregate contains moisture, the bond strength with other additives, for example, with the sulfur polymer, is reduced because of the moisture. In addition, when the aggregate is heated in advance, there is an effect that a smooth mixing operation can be performed without dropping the temperature when it is put into the blender.

2 is a cross-sectional view of the heating unit 14 for heating the aggregate and the like accommodated in the hopper 10. The MSPC composition mixing device of the present invention can be accommodated in the hopper 10 in a state where the aggregate is heated to a predetermined temperature by providing the heating unit 14. Thus, continuous production is possible without the operation being interrupted, and it is possible to prevent the temperature of the MSPC composition from being lowered during the mixing operation in the mixer 30.

Referring to the drawings, the heating unit 14 is installed on the side of the hopper 10 and the inside of the case 15 is formed of a double hollow, the fruit oil 16 is accommodated in the inner hollow of the case 15, the case ( Insulation material 17 is inserted into the outer hollow of the 15, and a heating member 18 for heating the fruit oil (16).

The fruit oil 16 is heated by the heating member 18, which will be described later, circulates inside the case 15, and maintains the aggregate inside the hopper (see Fig. 1:10) at a predetermined temperature. When the aggregate inside the hopper 10 is heated using the fruit oil 16, it can be heated more uniformly than when directly heated using a heater. The fruit oil 16 is stable to pyrolysis and oxidation, does not corrode metal, and has adequate fluidity at the temperature used. One side of the case 15 may be formed with a hole (not shown) for injecting or taking out the fruit oil 16. In addition, the fruit oil 16 is thermally expanded in accordance with the temperature rise, so it is preferable to fill the inside of the case 15 leaving a free space capable of thermal expansion rather than completely filling the fruit oil 16. If the fruit oil 16 is completely filled in the case 15, a pressure control valve such as a safety valve for adjusting the pressure when the temperature of the fruit oil 16 rises, or a separate margin is provided. It is desirable to form a space. However, some heaters have a space in which the fruit oil can expand. Therefore, such a heater does not require a pressure control valve or a separate free space.

The heating member 18 heats the fruit oil 16. Preferably, the heating member 18 is a heater installed inside the fruit oil 16 layer. The number and location of heaters are determined by considering the required temperature and the amount of aggregate. More preferably, the inner hollow part of the case 15 is doubled, and the inner hollow part accommodates the fruit oil 16, and the outer hollow part outside the fruit oil 16 layer surrounds the fruit oil 16 layer. The heat insulating material 17 is inserted. The heat insulating material 17 prevents the heat of the fruit oil 16 from dissipating to the outside. 2 illustrates a heating member 18 such as a heater installed inside the fruit oil 16 layer, but has various structures such as a heating wire surrounding the fruit oil 16 layer or a heater installed outside the fruit oil 16 layer. Heating elements are possible. In addition, a heating wire or a heater may be installed on the outer surface of the hopper 10 without a heat oil 16 layer to directly heat the inside thereof.

Meanwhile, as an alternative to the heating member 18, the fruit oil 16 is heated using a heater (not shown) installed outside the hopper 10, and the heated fruit oil 16 is circulated using a pump or the like. The method of heating the hopper 10 is also possible by doing so. That is, a case having a hollow formed therein is installed in the hopper 10, and the fruit oil is heated using a heater installed outside the hopper 10 while circulating the fruit oil through the circulation pipe communicating with the hollow.

Referring back to FIG. 1, a meter 20 is installed below the hopper 10. The meter 20 has a load cell although not shown in the figure. In the present invention, a load cell having a conventional structure is used, and the coarse aggregate and the fine aggregate are dropped by the load cell downward by a predetermined amount.

The mixer 30 is installed at the lower portion of the meter 20 to mix the aggregates dropped from the meter 20 with SPC supplied through a separate line (not shown), pigments, and the like to mix the MSPC composition.

SPCs, such as sulfur polymers used in the present invention, as disclosed in Patent Publication No. 1983-2618, dicyclopentadiene, methyl cyclopentadiene, divinyl benzene, cyclooctadiene, cyclodecatriene, octa 5 to 20% by weight of a first hydrocarbon selected from dienes and myrcene (for sulfur) and 5 to 20% by weight of a second hydrocarbon selected from dipentene, styrene, vinyltoluene, pinene and octene (for sulfur) It is prepared by reacting at a temperature sufficiently high to generate an exothermic reaction, that is, 120 to 200 ° C. The SPC has a transmittance of 5 to 100, a softening point of 10 to 70 ° C. and a ductility of at least 100, and the heat transfer rate is considerably low. SPC is present in the solid phase below 100 ~ 110 ℃, it exists in the liquid phase at higher temperatures, 150 ~ 160 ℃ or more, changes in physical properties such as the viscosity increases and the sulfur component is discharged. Therefore, in order to mix MSPC composition using SPC, it is preferable to maintain the temperature of 130-140 degreeC.

The mixer 30 has heating means (not shown) for heating the interior thereof and conventional stirring vanes. The heating means heats the blender 30 by heating the fruit oil using a heater (not shown) installed outside the mixer and circulating the heated fruit oil using a pump or the like. Thus, the mixing apparatus 100 of the present invention can mix the MSPC composition without lowering the temperature by heating the inside of the mixer 30 to a predetermined temperature.

As an alternative to the heating method, the heating means may have the same structure as the heating unit 14. That is, the heating means includes a case in which a hollow is formed in the inside, a fruit oil accommodated in the inner hollow of the case, a heat insulating material inserted into the outer hollow of the case, and a heater for heating the fruit oil. That is, the fruit oil heated by the heater heats the inside of the mixer 30.

The heating part 34 is installed in the door 32 formed below the mixer 30.

The heating part 34 maintains a constant temperature by heating the MSPC composition inside the mixer 30 adjacent to the door 32. That is, the door 32 is easily opened and closed by keeping the MSPC composition in a molten state. In addition, the heating unit 34 allows the door 32 to be opened and closed more easily by heating and changing the MSPC composition to a molten state when the temperature of the mixer 30 decreases so that the MSPC composition solidifies. Meanwhile, in the present specification, the 'MSPC composition is melted' means that the MSPC composition is in a state in which it can flow without being solidified, that is, it can be poured into a mold.

As illustrated in FIG. 3, the heating unit 34 includes a case 40 installed on one surface of the door 32. Although not shown in the figure, the interior of the door 32 case 40 has a structure similar to that of the case (15 of FIG. 2) installed in the hopper 10. That is, the inner hollow part of the case 40 is doubled, and the inner hollow part receives the fruit oil, and the heat insulating material surrounding the fruit oil layer is inserted into the outer hollow part outside the fruit oil layer. The insulation prevents the heat of the fruit oil from dissipating to the outside. A heating member such as a heater is installed inside the fruit oil layer to heat the fruit oil to a predetermined temperature.

In addition, as an alternative to the heating member installed inside the fruit oil, the fruit oil is heated using a heater (not shown) installed outside the heating unit 34, and the heated fruit oil is circulated using a pump or the like door. (32) can also be heated. That is, the heating unit heats the case having the hollow formed therein, the fruit oil circulated in the hollow of the case and circulated through the hollow and the circulation pipe (not shown) by a pump, and the fruit oil circulated outside the mixer. With a heater.

Another embodiment of the heating unit 34 may include a heat transfer plate 50 inserted into the door 32 ', as shown in FIG. Preferably, the heat transfer plate 50 is made of a metal having high electrical resistance, and generates heat by applying heat to the heat transfer plate 50 to maintain the MSPC composition inside the mixer 30 at a constant temperature.

The heating unit 34 of the present invention is not limited to the above-described embodiment, and may be appropriately modified and adopted by those skilled in the art.

On the other hand, the door used in the blender 30 has a sliding method, a method in which only one door is installed, two doors are installed and opened on both sides, there is a variety of methods such as a rotating method of rotating the door, the heating unit of the present invention Installation is not limited by the structure of the door, and can be appropriately modified by those skilled in the art to which the present invention belongs and applied to doors of various structures.

MSPC composition mixing apparatus according to the present invention has the following effects.

First, the blender and the blender door are heated so that the MSPC composition housed inside the blender can be mixed at a constant temperature.

Second, since the MSPC composition near the door is kept molten by the heating unit of the blender door, the door is easily opened and closed. In particular, even when the mixer is cooled to solidify the MSCP composition and the door is not opened or closed, the door may be opened and closed more easily by heating and melting the MSPC composition using a heating unit.
