Description

Apparatus and method for manufacturing heat insulating perlite}

The present invention relates to an apparatus and method for manufacturing a pearlite insulating material, and more particularly, to an apparatus and method for heating and sintering a pearlite paste, which is a mixture of pearlite and sodium silicate No. 3, at a high temperature of 300 ° C. or higher with a microwave.

In general, perlite is a mineral selected from the group consisting of perlite, obsidian, pumice, etc., which is finely pulverized and heated at high heat (900 ~ 1200 ° C) to gasify the contained volatile components and expand inside the softened particles. As a result, internal pores are formed, and the pearlite expands to about 10 to 20 times its original volume. This expansion is due to the volatile components of perlite contained in the crude perlite rock.

In addition, perlite is a type of rhyolite rock, and is also called pearlite because it has pearlescent light gray to dark gray, brown, green, and black colors. Although this pearlite differs depending on the structure of the rock, the evaporation pressure generated by the evaporation of the bound water at about 870 ° C to 1,100 ° C expands each granular particle into a circular glassy particle by about 10 to 20 times, and is used commercially. The expanded perlite is low-density, porous, has good absorption capacity, and has properties such as light weight, heat insulation, heat retention, sound absorption, non-toxicity and non-flammability, and is widely used as heat-resistant material, soundproofing material, lightweight aggregate and insulating material. .

In order to manufacture a perlite insulator in a conventional manner, the expanded perlite was heated with a hot plate above and below the insulator. Hundreds of kw of electricity must be used to heat a huge hot plate to 250 ° C or higher to sinter pearlite, and it is difficult to afford high fuel costs even when using high-temperature gas of 250 ° C or higher. In particular, when the thickness of the panel is 100 mm or more, it is difficult to sinter pearlite only by heating, and a lot of heating time is required to transfer high heat of 250 ° C. or more to the inside of the panel.

In order to solve the above problems, Patent Publication No. 10-2012-0020258 discloses a method of emitting microwaves by a magnetron to radiate and sinter pearlite materials with a reflector.

However, this method also radiates microwaves only from the upper part, so that the microwaves are not transmitted to the lower part of the panel, so that the upper and lower parts of the panel are not uniformly sintered. In addition, the thickness of the panel for sintering also has a limit that cannot exceed 100 mm or more.

In addition, this method has a problem in that the strength of the pearlite insulator is low because complete sintering does not occur because the thickness of the pearlite insulator cannot be adjusted in the forming roller.

An object of the present invention is to provide a pearlite insulating material manufacturing apparatus and method capable of uniformly sintering the pearlite paste by irradiating microwaves on the upper and lower surfaces of the pearlite paste.

Another object of the present invention is to provide a pearlite insulating material manufacturing apparatus and manufacturing method capable of completely removing water vapor generated inside the pearlite paste by gradually reducing the thickness after sintering the pearlite paste a plurality of times.

The first forming roller 20 presses the pearlite paste located on the conveyor belt 30 in one direction with a single roller to form the pearlite paste to a first thickness.

The conveyor belt 30 is disposed at both ends and rotates infinitely by the driving pulley 70 connected to the driving device 80 to transport the pearlite insulation, and the first guide roller 50 to the fourth guide roller 53 According to the guidance, it contacts the first forming roller 20, moves along the outer circumference of the second forming roller 21 and the third forming roller 22, and moves along the lower part of the magnetron box 40, 41, 42.

The magnetron boxes 40, 41, and 42 irradiate the upper and lower surfaces of the expanded pearlite paste so that microwaves can penetrate into the expanded pearlite paste in both directions in the thickness direction of the expanded pearlite paste.

1 and 2, in order to prevent deformation of the pearlite paste due to rapid internal expansion when high-frequency microwaves are irradiated to the pearlite paste, the first magnetron box 40 to the third magnetron box 42 transmits microwaves to the pearlite The paste is irradiated for 3 to 4 minutes each.

Referring to FIG. 4, the first forming roller 20 to the fourth forming roller 23 according to the present invention include a cylindrical roller bearing 200 to minimize distortion of the upper and lower rollers to produce a precise pearlite insulator.

In addition, the second forming roller 21 includes a first upper roller and a first lower roller, and the third forming roller 22 includes a second upper roller and a second lower roller to produce an expanded pearlite paste, which is a molded product. Uniform pressure is applied to the upper and lower surfaces of the expanded pearlite paste by passing it between the first upper roller and the first lower roller and between the second upper roller and the second lower roller.

In addition, the second shaping roller 21 and the third shaping roller 22 together with the roller bearing 200 are a tower combine that vertically moves the first upper roller, the first lower roller, the second upper roller, and the second lower roller. (Tower Combine) 210 is included so that the height of the first and second upper and lower rollers can be adjusted, so that the pearlite insulator can be molded into various thicknesses.

The first thickness of the pearlite paste formed by the first forming roller 20 is greater than the second thickness, and the fourth thickness of the pearlite insulator formed by the fourth forming roller 23 is smaller than the third thickness.

In this case, the difference between the first thickness and the second thickness of the pearlite paste is molded smaller than the difference between the second thickness and the third thickness.

Hereinafter, a method for manufacturing a perlite insulator by the apparatus for manufacturing a perlite insulator according to the present invention will be described with reference to the drawings.

5 is a flow chart showing a method for manufacturing a pearlite insulating material according to an embodiment of the present invention. 6 is a conceptual diagram showing the behavior state and principle of water molecules for sintering of pearlite paste by microwave according to the present invention.

Referring to FIGS. 1 and 5, first, an expanded pearlite paste is prepared (S10).

Heat the perlite to a high temperature of about 900 ° C to 1200 ° C to sufficiently expand it. Expanded perlite is pulverized to have particles of approximately several micrometers to hundreds of micrometers.

Next, 37% to 42% by weight of expanded pearlite and 45% to 50% by weight of liquid sodium silicate No. 3, neutralization of sodium contained in sodium silicate No. 3 and aluminum phosphate, zinc phosphate as a hardener (zinc phosphate) and magnesium phosphate (magnesium phosphate) by mixing at least one selected from the group consisting of 8% by weight to 13% by weight to form an expanded pearlite paste.

At this time, when sodium silicate No. 3 exceeds 50% by weight, water resistance decreases due to excessive content of sodium silicate No. 3, and flame retardancy decreases when it is less than 45% by weight.

Referring back to Figures 1 and 5, the expanded pearlite paste is put into the supply feeder 10 and supplied on the conveyor belt 30 at a constant flow rate (S20).

The supplied expanded pearlite paste controls the thickness of the pearlite paste while passing through the first forming roller 20 before the sintering process.

The first forming roller 20 presses the pearlite paste at a pressure of 490Mpa to 980Mpa. The first forming roller 20 is a single roller that presses the pearlite paste located on the conveyor belt 30 in one direction to form the pearlite paste to a first thickness.

Next, the expanded pearlite paste passing through the first forming roller 20 is first sintered in the first magnetron box 40 (S30).

At this time, the conveyor belt 30 moves to the lower part of the first magnetron box 40 by the rotation of the first guide roller 50 and is separated from the expanded pearlite paste.

The expanded pearlite paste separated from the conveyor belt is put into the first magnetron box 40 . The first magnetron box 40 includes at least one magnetron 400 generating microwaves at upper and lower portions. The magnetron 400 irradiates microwaves to the upper and lower surfaces of the expanded pearlite paste, respectively.

Referring to FIG. 6, when microwaves are irradiated into the expanded pearlite paste, (-) electrons, which are hydrogen atoms of H2O, which are water molecules in the pearlite, are biased to the left side of oxygen (115). The side of the oxygen atom has (-) polarity (114). Electric waves and magnetic fields are connected like a chain, and the (+) direction (112) and (-) direction (113) move while changing polarity with each other. At this time, when (+) energy of microwave is applied to water molecules, oxygen atoms with (-) polarity are attracted to the radio wave and turn their direction. When (-) energy of microwaves is applied to water molecules, hydrogen atoms with (+) polarity are attracted and change direction. Accordingly, water molecules have kinetic energy due to a change in direction according to their polarity, and become water vapor.

The first magnetron box 40 irradiates the upper and lower surfaces of the expanded pearlite paste so that microwaves can penetrate into the expanded pearlite paste in both directions based on the thickness direction of the expanded pearlite paste.

The first magnetron box 40 uniformly sinters the expanded pearlite paste, shortens the sintering time, and can manufacture an expanded pearlite insulation having a thickness of 10 mm or more, unlike conventional methods.

In addition, the first magnetron box 40 maintains an internal temperature at 250° C. to 300° C. by means of an air-cooled or water-cooled cooling device.

Next, the pearlite paste primarily sintered in the first magnetron box 40 is placed on a conveyor belt raised from the lower part of the first magnetron box 40 . In this case, the primary sintered pearlite paste is expanded in the sintering process to have a larger thickness than the first thickness.

The primary sintered pearlite paste located on the conveyor belt passes through the second forming roller 21. At this time, the conveyor belt moves along the outer circumference of the lower part of the second forming roller 21 and is separated from the firstly sintered expanded pearlite paste.

The primary sintered pearlite paste to a second thickness smaller than the first thickness is molded by the second forming roller 21 (S40).

The second forming roller 21 includes a first upper roller and a first lower roller and passes the primarily sintered expanded pearlite paste between the first upper roller and the first lower roller to uniformly form the upper and lower surfaces of the expanded pearlite paste. puts pressure on

In addition, the second forming roller according to the present invention includes a cylindrical roller bearing 200 to minimize distortion of the upper and lower rollers to produce a precise pearlite insulator.

The second shaping roller 21 includes a tower combine 210 that moves the first upper roller and the first lower roller up and down together with the roller bearing 200, so that the first upper and lower rollers and the first lower roller The height can be adjusted, so the perlite insulation can be molded into various thicknesses.

The second forming roller 21 molds the expanded pearlite paste at a pressure of 490Mpa to 980Mpa by adjusting the height of the first upper roller and the first lower roller by the tower combine 210.

Next, the pearlite paste passing through the second forming roller 21 is secondarily sintered in the second magnetron box 41 (S50).

At this time, the conveyor belt 30 moves to the lower part of the second magnetron box 41 by the rotation of the first guide roller 51 and is separated from the expanded pearlite paste.

The expanded pearlite paste separated from the conveyor belt 30 is put into the second magnetron box 41.

The second magnetron box 41 includes at least one magnetron generating microwaves at upper and lower portions.

The magnetron irradiates microwaves to the upper and lower surfaces of the expanded pearlite paste, respectively.

The pearlite paste secondarily sintered in the second magnetron box 41 is placed on the conveyor belt 30 elevated from the bottom of the second magnetron box 41 .

The secondary sintered pearlite paste located on the conveyor belt 30 passes through the third forming roller 32. At this time, the conveyor belt moves along the outer circumference of the lower part of the third forming roller 22 and is separated from the secondly sintered expanded pearlite paste. The secondary sintered expanded pearlite paste passes between the upper and lower rollers of the third forming roller 22 .

The third forming roller 22 includes a second upper roller and a second lower roller to pass the expanded pearlite paste, which is a molded product, between the second upper roller and the second lower roller to achieve uniform pressure on the upper and lower surfaces of the expanded pearlite paste will add

Accordingly, the secondary sintered pearlite paste passing through the second magnetron box 41 passes through the third forming roller 22 to form the pearlite paste into a third thickness smaller than the second thickness.

In this case, the difference between the first thickness and the second thickness of the pearlite paste is molded smaller than the difference between the second thickness and the third thickness.

Next, in the same manner as above, the pearlite paste that has passed through the third forming roller 22 is sintered tertiarily in the third magnetron box 42 (S60).

The pearlite paste is sintered by the third magnetron box 42 to manufacture a pearlite insulation panel.

Next, the pearlite insulation panel discharged from the third magnetron box 42 is put into the grinding box 60 by the fourth forming roller 23, and the surface of the pearlite insulation panel is polished (S70).

In this case, the fourth forming roller 23 moves the pearlite insulation panel to the grinding box 60 together with the conveyor belt 30 without changing the thickness of the pearlite insulation panel.

The polishing box 60 polishes one surface of the perlite insulation panel. When the pearlite insulation panel moves on the conveyor belt, the polishing box 60 polishes one surface of the pearlite insulation panel to a roughness of 100 μm to 300 μm.

Although not shown in the drawing, if necessary, the other surface of the perlite insulation panel may also be finished by processing the surface by another grinding box.

In addition, although not shown in the drawing, rock powder having various colors may be applied to the surface of the polished pearlite insulation panel.
