Description

Heat-resistant block set and assembly incinerator

The present invention relates to a heat-resistant block set that is a unit set of parts for assembly of devices (including heat-resistant structures) used in a thermal environment, and an assembly incinerator that is an example of a device that is assembled using the heat-resistant block set. .

The thermal environment is an environment that requires heat insulation due to a high temperature, for example, an environment that comes into contact with a direct fire, or a high temperature environment corresponding to the environment. There is an incinerator as an apparatus used in a thermal environment. Incinerators are generally assembled at a factory and carried to an installation location. On top of that, a building that surrounds the incinerator may be built.

However, when replacing an old incinerator with a new one due to the failure of the incinerator or the end of its useful life, the old incinerator can be disassembled and transported from the entrance of the building, even if it is large. As it is, it cannot be carried into the building from the entrance. In such a case, the building is partially disassembled and an incinerator is installed, then the building is restored, and the incinerator replacement and installation costs are expensive.

On the other hand, if there is no access road to the installation location, or transport vehicles cannot enter, for example, it is extremely difficult to carry in large incinerators to difficult-to-carry areas such as mountainous areas, remote islands, overseas, and remote areas. Cost becomes high.

On the other hand, the inventor has already developed an incinerator for removing harmful substances (Patent Document 1) and is used in local environment as well as normal use environment. The incinerator of patent document 1 makes the downstream of a primary combustion chamber a negative pressure, and burns the to-be-incinerated thing of a primary combustion chamber by the flow of the negative pressure air drawn in (refer nonpatent literature 3).

The inventor has also developed a combined incinerator that can be transported and installed in places where it is difficult to carry in (Patent Document 2). In the invention of Patent Document 2, the conventional incinerator can be installed in remote islands, mountainous areas, high mountains, deep forests and rugged places, remote areas, buildings without elevators, rooftops, basements, narrow roads, etc. In addition, when assembling the incinerator, assembly equipment such as a large crane was required, so anyone could not easily assemble the incinerator, so the incinerator members were subdivided for assembly and installation. There is no need for a long period of time, no cost, the size of the incinerator can be easily changed, no skilled technicians are required for maintenance, and the capacity of the incinerator is not limited. Unnecessary union incinerator,
Casters (fireproof cement) that can be freely changed in combination to form an incinerator and consists of an outer wall material composed of an outer wall, a heat insulating material, and a refractory material, and a heat insulating material and a refractory material constituting the outer wall material. ), Caster locking bolts that can be bolted from the caster to the outer wall, a tapered pin that connects the outer wall material and the outer wall material, and an outer wall that fills the gap between the outer wall and the outer wall when using the outer wall material and the outer wall material pin It comprises a seal packing (claim 1).

However, the refractory material of Patent Document 2, the outer wall that fixes the refractory material, the heat insulating material, the pins, and the like have a complicated structure and low versatility. In addition, bricks, which are refractory materials, were placed inside the device, but the side walls (ribs) stood outside the outer wall, and the adjacent outer walls were connected there, so water accumulated between the ribs. There are problems such as rust and deterioration due to the above, and when painting and decorating on the outside, the structure must be extremely complicated.

1) Heat-resistant block set components are small, simple structure, high manufacturability, distribution and versatility, are inexpensive, and are connected by bolting, facilitating device assembly and assembly at the installation location. In addition, the positioning hole can increase the assembly accuracy of the apparatus.
2) With the screw tightening system of the present invention, it is possible to assemble even in a small place by one person. In addition, since the exterior is flat, it is possible to attach a metal sheet, print a pattern or pattern on the sheet, or use a printed sheet, to improve the appearance of the appearance, and to prevent rain leakage and corrosion. it can.
3) The design can be freely changed in structure and scale from small to large. Since it can be transported by existing home delivery and mail parcels, transportation costs can be reduced. Further, only deteriorated parts can be transported and replaced, the maintenance cost of the apparatus can be suppressed, and the useful life of the entire apparatus can be extended. Introduced, the device size can be changed in the middle, heat resistant block set can be added, it can be increased in size, and it can be reduced except heat resistant block set. At that time, the usage capacity can be changed and the running cost of the device is suppressed, Can be optimized.

5) For example, the structure of the primary and secondary chambers of the incinerator may be a steel plate or heat-resistant plastic on the outer wall, a heat insulating board on the second layer toward the inside, and a refractory caster structure on the third layer. Also, the secondary combustion chamber has the same structure, and the assembly can be done by anyone by using a bolt tightening structure. On the other hand, it can also be assembled into a wood stove container in a private home. In addition, devices used in a thermal environment such as stoves, fireplaces, furnaces, kilns, and boilers can be assembled.

By using a heat-resistant block set, parts can be brought in early (2 weeks to 1 month) and assembled. This contributes to relief and reconstruction of disaster victims in an emergency such as a disaster. In addition, since the fireproof block can be about 40 kg, it can also be transported by drone, so it is possible to transport the assembly parts of the device to mountains and small islands even in places where ships or cars cannot pass due to earthquakes, tsunamis, etc. Therefore, the apparatus can be used for assembly after being transported. In addition, human power, helicopter trucks and small ships can be transported to the installation site.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In addition, this invention is not limited to the following Example.

As shown in FIGS. 1 and 2, an example of the heat-resistant block set according to the present invention includes an outer wall 2, a heat insulating board 3, a refractory brick 4, and a bolt 5 which is an example of a fixing means.

As shown in FIG. 2 (A), the outer wall 2 includes a frame 2d having a side surface 2h upstanding on the exterior surface 2g and a female screw provided on the thermal environment surface side of the exterior surface 2g, such as welding, for example by welding. And a nut 2a fixed to the nut. Examples of the material of the outer wall 2 include steel plates and heat-resistant plastics.

The side surface 2h of the frame 2d is provided with a hole 2c for inserting a bolt and connecting the heat-resistant block sets 1 to each other with a bolt and a nut. Furthermore, prior to the bolt / nut connection of the side surface 2h of the outer wall 2, a pin hole 2b is provided for high-precision positioning between the frame bodies 2d of the heat-resistant block set 1. The pin hole is accurately positioned and previously drilled. When assembling the device, by inserting a pin into the pin hole 2b, the outer walls 2 can be accurately guided, for example, the guides are arranged flat on the outside. Assembly accuracy is extremely high. It is easier to drill one small-diameter pin hole than to drill two bolt holes with high accuracy. It is also possible to drill the bolt hole position and diameter with high precision, but since existing bolts that are generally distributed do not have high molding accuracy, the bolt is used when the bolt hole is drilled with high precision. There are things that cannot be done. In order to improve the alignment accuracy of the outer wall 2, positioning using the pin holes 2b and the pins is extremely effective.

The heat insulating board 3 is a so-called gypsum board or the like, and here, as shown in FIG. 2 (B), a vertical hole 3a drilled through vertically at a position corresponding to the position of the nut 2a of the outer wall 2 is provided. And is disposed on the inner thermal environment surface side of the outer wall 2. A bolt 5 described later is inserted through the vertical hole 3a.

The refractory bricks 4 are arranged side by side on the surface of the heat insulation board 3 and, as shown in FIG. 2 (C), communicate with the first hole 4a and the first hole 4a drilled on the heat insulation board 3 side. A second hole 4b that penetrates to the surface side and has a diameter larger than that of the first hole 4a is provided. Between the refractory bricks 4, in order to ensure airtightness and heat retention, a heat-resistant packing seal is sandwiched and applied.

The bolt 5 which is an example of a fixing means is inserted into the first hole 4a of the refractory brick 4, and is screwed into a male screw which is screwed into the female screw, and a stepped portion 4c between the first hole 4a and the second hole 4b. The heat-resistant brick 4 is positioned between the outer wall 2 while pressing the fire-resistant brick 4 against the heat-insulating board 3 by screwing the male screw and the female screw.

The second hole 4b of the refractory brick 4 is sealed with a heat-resistant cement 6 after the bolts 5 are screwed together. This is to prevent deterioration of the bolt due to heat. Furthermore, the deterioration of the screw head of the bolt 5 is further suppressed by inserting a heat-resistant packing between the bolt 5 and the cement 6. The reason why the bolt 5 is prevented from deteriorating is that when the refractory brick 4 and the heat-resistant block set 1 are replaced, it is necessary to unscrew the bolt in order to be detached from the apparatus.

In the heat-resistant block set 1 thus formed, another heat-resistant block set 1 is connected to the side surface 2h of the outer wall 2 by connecting means 9, as shown in FIG. The connecting means 9 inserts a pin into the pin hole 2b on the side surface 2h of the outer wall 2, positions the outer walls 2 and then connects them with bolts and nuts to form a desired shape and size in any plane direction. We ’ll expand it to make it happen. At that time, a heat-resistant seal bond is applied to the joint to ensure airtightness between the heat-resistant block sets (outer walls).

¡As a result, we will build up equipment (mainly spaces exposed to heat and flow paths) used in a thermal environment. In addition, prepare heat-resistant block sets of necessary shapes such as corners and door opening and closing. Basically, 95% of the configuration of an incinerator is not a special product, but can be assembled by repeating standard products, such as plastic models, building blocks, and LEGO blocks (registered trademark). In addition, by incorporating necessary electrical equipment, unit units can be brought into the field and equipment can be easily assembled on site.

If such a heat-resistant block set 1 has a unit of about 40 cm square, the weight can be reduced to 30 kg or less, and the required quantity of units and replacement parts can be transported and transported and replaced by a general home delivery service. Cost can be kept low.

Also, the exterior surface of the assembled device is flat with joints. Therefore, when a metal seal is affixed to the exterior surface of the exterior surface 2g, airtightness and appearance are improved, and rain leakage and corrosion are suppressed.

Next, another embodiment will be described. As shown in FIG. 3, another embodiment of the heat-resistant block set according to the present invention is an outer wall 2 f in which the nut 2 a of the outer wall 2 is changed to a metal fitting 7 in the first embodiment. The metal fitting 7 forms both left and right vertical plates 7c by pressing both ends of a steel material or stainless steel material in a U-shape, and further forms a convex portion 7b between the vertical plates 7c. Then, a female screw (screw hole 7a) is formed in the top plane of the convex portion 7b. By forming the convex portion 7b, a space 7e into which the male screw of the bolt 5 is fitted can be secured. A hole 7d is formed in the vertical plate 7c, and bolts and nuts 8 are inserted into the hole 2c and the hole 7d on the side surface 2h of the frame 2d, and the receiving bracket 7 is fixed to the frame 2d as described later.

In order to fix the bracket 7 to the frame 2d, spot welding may be performed on the exterior surface 2g at several locations of the bracket 7. As a result, the number of weldings can be reduced and the manufacturing cost can be reduced as compared with welding the nut 2a to the exterior surface 2g, and the accuracy of the mounting position of the female screw is stabilized.

Further, as shown in FIG. 3 (A), if the metal fitting 7 is fixed to the frame 2d with bolts and nuts 8, a welding process is not required, and the metal fitting 7 is also attached to the frame 2d at the local assembly site of the apparatus. The outer wall 2f can also be assembled by being fixedly connected to each other. Furthermore, if the bolts and nuts 8 are shared between the other outer walls 2f connected to the side surface 2h of the outer wall 2f and are used for fixing the respective brackets 7 to the frame 2d, the number of parts is reduced and the cost is reduced. Can be suppressed.

When the bolts and nuts 8 are used to fix the frame 2d and the metal fitting 7, the heat insulation board 3 may be cut out so as to avoid the bolts and nuts 8. On the other hand, a method may be used in which only one lower stage of the bolts and nuts 8 is used, and the lower part of the heat insulating board 3 is cut out for one week so that the bolts and nuts 8 do not get in the way. As shown in FIG. 3A, a heat insulating board 3b that is slightly smaller may be used so as not to contact the protruding portion of the bolt and nut 8.

Note that, as shown in FIG. 3 (E), a metal fitting 7f in which a screw hole 7g, which is a female screw, is formed in a thick steel plate may be used without providing the convex portion 7b on the metal fitting. The fixing means to the frame 2d may be the same as that of the receiving metal fitting 7. If it is the receiving metal fitting 7f, there will be no effort of shaping | molding the convex part 7b, and manufacturing cost will be held down.

Next, a negative pressure assembly incinerator that is assembled using a heat-resistant block set will be described. As shown in FIGS. 4 to 8, the mechanism and structure of the negative pressure type assembly incinerator are disclosed in detail in cited

documents

1 and 2, patent document 1, and the like. Here, the floor 12 is also assembled by connecting heat-resistant block sets.

The assembly procedure of the apparatus using the heat-resistant block set 1 and the case where the frame bodies 2d are connected to each other in the side surface 2h direction of the frame body 2d will be described. First, a pin is inserted into a pin hole 2b that is positioned and drilled in the side surface 2h with high accuracy, and the

frame bodies

2d and 2d are temporarily fixed. As a result, the frames 2d are arranged and temporarily fastened with high accuracy. At this time, a heat-resistant (−60 ° C. to 200 ° C.) bond or seal material may be used for the side surface 2h in order to enhance the airtightness of the assembled device and adhere, for example, a fluid silicone gasket can be used. .

In the temporarily fastened state, the frames 2d are connected to each other by connecting means 9, for example, bolts and nuts. Thereafter, the heat insulating board 3 is fitted in the frame 2d, and then the firebrick 4 is placed on the surface of the heat insulating board 3, and then the bolt 5 is attached to the first hole 4a and the second hole 4b of the firebrick 4. , Through the vertical hole 3a, screwed into the female thread of the outer wall 2 (nut 2a in the case of Example 1, screw

holes

7a, 7g in the case of Example 2), and tightening the heat insulating board 3 with the fire brick 4, The heat insulating board 3 and the refractory brick 4 are fixed inside the outer wall 2.

After that, heat-resistant cement 6 is filled in the second hole 4b of the refractory brick 4. As described above, it is more desirable to place the heat-resistant packing on the bolt 5 and then fill the cement 6 with the bolt 5 to suppress deterioration of the bolt 5.

At this time, it is better to sandwich a heat-resistant packing sheet between the refractory bricks 4, and further, when filling the joint portion in the thermal environment direction between the refractory brick 4 and the refractory brick 4 with the heat-resistant cement. Higher heat insulation is ensured.

As shown in FIGS. 4 and 5 (gray portion), the primary combustion chamber 13, the inlet door 13 a into which the combusted material is introduced, the ash outlet chamber 14, the machine chamber 15, and the machine constituting the negative pressure type incinerator 11. A cyclone 16 or the like installed in the chamber 15 and having the secondary combustion chamber 16a inside can be assembled using the heat-resistant block set of the present invention.

Then, a machine and appliances such as a blower 16b that makes the primary combustion chamber 13 a negative pressure, a burner 16c that causes secondary combustion, and a chimney 17 are attached and completed. Desirably, a metal sheet is affixed to the appearance portion to improve airtightness, prevent leakage and deterioration, and improve the appearance. If the combustion chamber is large, ribs 19 may be used to reinforce the U-shaped ribs 19 in contact with the left and right and top surfaces of the primary combustion chamber.

Next, heat-resistant block sets with other shapes will be described. As shown in FIG. 6, the primary combustion chamber 13 and the inlet door 13a can all be assembled from heat-resistant blocks. As shown in FIG. 7, in addition to a standard product of the heat-resistant block set 1, a heat-resistant block 1 set 1 a such as a square member 13 g constituting a corner portion is prepared. The square member 13g has an L-shaped exterior surface, and the refractory bricks 4 are arranged in a row using a heat insulating board fitted thereto. The means for fixing the refractory brick 4 to the outer wall 2 i is the same as that of the heat-resistant block set 1. In addition, in FIG. 7, the joint is in the state which cannot be visually recognized by omission or the metal sheet sticking in the exterior surface 2g of the heat-resistant block set 1. FIG.

Further, as shown in FIG. 8, a part having a part of the side surface that is the exterior surface 2g, a thing in which the firebrick 4d is inclined to a necessary shape, and the like are also used. However, incinerators have few special products, and 95% can be assembled by repeatedly combining standard products.

Of course, a general incinerator can be assembled without being limited to the negative pressure incinerator. Furthermore, a desired scale can be easily assembled like a three-dimensional puzzle in a variety of shapes of devices used in a thermal environment.
