Abstract
Description
[Technical Field]
[0001] The present invention relates to an insulation cover. [Background technology]
[0002] BACKGROUND ART Conventionally, heat insulating materials have been used in industrial machines such as heat exchangers, mainly for the purpose of keeping the temperature of catalysts constant (see, for example, Patent Document 1).
[0003] An example of the above-described industrial machinery is an SCR device 100 as shown in FIG. 8. This SCR device 100 is designed to remove harmful substances from exhaust gas emitted from a ship engine. Thus, two inspection hatches 100b, each with a pair of handles 100a, are provided on the front of the SCR device 100, one above the other, as shown in FIG. 8. Furthermore, as shown in FIG. 8, heat insulating components 101 are installed in the inspection hatches 100b by fitting them into the respective pairs of handles 100a.
[0004] The heat insulating component 101 is composed of a heat insulating material 101a and a heat insulating material cover 101b shown in Fig. 9(a). The heat insulating material 101a is made of glass fiber and is formed in a rectangular shape as shown in Fig. 9(a). The heat insulating material 101a formed in a rectangular shape has a pair of elongated rectangular recessed notches 101a3 formed from the right side surface 101a1 toward the left side surface 101a2 as shown in Fig. 9(a).
[0005] On the other hand, the heat insulating material cover 101b is made of glass cloth or the like and is formed in the same shape as the heat insulating material 101a, as shown in FIG. 9(a). The heat insulating material cover 101b formed in this manner is hollow inside and has an open left side surface 101b1 side, as shown in FIG. 9(a). As a result, the heat insulating material 101a is inserted into the heat insulating material cover 101b from the left side surface 101b1 side of the heat insulating material cover 101b, as shown in FIG. 9(a). Once the heat insulating material 101a is inserted into the heat insulating material cover 101b, the open portion of the heat insulating material cover 101b is closed by, for example, sewing the left side surface 101b1 to the heat insulating material cover 101b. In this way, the heat insulating component 101 shown in FIG. 9(b) is manufactured.
[0006] Thus, by covering the heat insulating material 101a with the heat insulating material cover 101b, it is possible to prevent the glass fibers of the heat insulating material 101a from scattering. [Prior art documents] [Patent documents]
[0007] [Patent Document 1] Japanese Patent Application Laid-Open No. 2015-232991 Summary of the Invention [Problem to be solved by the invention]
[0008] However, because the heat insulating cover 101b described above covers the entire heat insulating material 101a, not only is the manufacturing cost very high, but the manufacturing process for the heat insulating cover 101b is very complicated because it must be made to have the same shape as the heat insulating material 101a. Furthermore, because the heat insulating cover 101b covers the entire heat insulating material 101a, it is difficult to check for deterioration of the heat insulating material 101a.
[0009] Therefore, in consideration of the above problems, the present invention aims to provide an insulation cover that can be easily manufactured and that can easily check for deterioration of the insulation. [Means for solving the problem]
[0010] The above object of the present invention can be achieved by the following means: Note that the parentheses indicate reference symbols of embodiments to be described later, but the present invention is not limited to these.
[0011] The heat insulating cover according to claim 1 is a heat insulating cover (for example, the heat insulating cover 1 shown in FIGS. 1 to 4, the heat insulating cover 1A shown in FIG. 5, or the heat insulating cover 1B shown in FIGS. 6 to 7) that is attached to a heat insulating material (for example, the heat insulating material 2 shown in FIG. 1) that is installed in an industrial machine (for example, the SCR device 100 shown in FIG. 8), The heat insulating material is composed of six surfaces, including an upper surface (for example, an upper surface 2a shown in FIG. 1(a)), a lower surface (for example, a lower surface 2b shown in FIG. 1(a)), and side surfaces (for example, a left side surface 2c, a right side surface 2d, a front side surface 2e, and a rear side surface 2f shown in FIG. 1(a)), The heat insulating cover is The heat insulating material is covered so that at least two of the six faces of the heat insulating material are exposed to the outside.
[0012] The insulation cover of claim 2 is characterized in that, in the insulation cover of claim 1, the insulation cover (e.g., the insulation cover 1 shown in Figures 1 to 4) sandwiches the insulation (e.g., the insulation 2 shown in Figure 1) to cover the upper surface (e.g., the upper surface 2a shown in Figure 1(a)) and the lower surface (e.g., the lower surface 2b shown in Figure 1(a)) of the insulation, and also covers one of the four side surfaces of the insulation (e.g., the left side surface 2c shown in Figure 1(a)).
[0013] The insulation cover of claim 3 is characterized in that, in the insulation cover of claim 1, the insulation cover (e.g., insulation cover 1A shown in Figure 5, insulation cover 1B shown in Figures 6 to 7) is formed into a cylindrical shape and sandwiches the insulation (e.g., insulation 2 shown in Figures 5 to 7), covering the upper surface (e.g., upper surface 2a shown in Figure 1(a)) and lower surface (e.g., lower surface 2b shown in Figure 1(a)) of the insulation, and also covering two of the four side surfaces of the insulation (e.g., left side surface 2c and right side surface 2d shown in Figure 1(a)). [Effects of the Invention]
[0014] Next, the effects of the present invention will be described with reference to the drawings. Note that the reference symbols in parentheses are those of the embodiments described below, but the present invention is not limited to these.
[0015] According to the invention of claim 1, the insulation cover (for example, the insulation cover 1 shown in Figures 1 to 4, the insulation cover 1A shown in Figure 5, and the insulation cover 1B shown in Figures 6 to 7) covers the insulation (for example, the insulation 2 shown in Figure 1) so that at least two of the six sides are exposed to the outside. This makes it possible to keep manufacturing costs low, as the insulation is not entirely covered as in the past. Furthermore, it is not necessary to make the insulation cover the same shape as the insulation, making it easier to manufacture. Furthermore, since the insulation cover does not entirely cover the insulation, it is easier to check for deterioration of the insulation.
[0016] Therefore, according to the present invention, it is possible to easily manufacture the heat insulating cover and also to easily check the deterioration of the heat insulating material.
[0017] As such an insulating material cover, an insulating material cover as described in claim 2 (for example, insulating material cover 1 shown in Figures 1 to 4) or an insulating material cover as described in claim 3 (for example, insulating material cover 1A shown in Figure 5, insulating material cover 1B shown in Figures 6 to 7) is suitable.

DETAILED DESCRIPTION OF THE INVENTION
[0019] Hereinafter, an embodiment of the heat insulating cover according to the present invention will be described in detail with reference to the drawings. In the following description, when directions such as up, down, left, and right are indicated, they refer to up, down, left, and right when viewed from the front of the illustration.
[0020] The heat insulating cover 1 shown in Fig. 1(a) is made of glass cloth or the like, and is composed of an upper cover 10, a lower cover 11, and a left cover 12. As shown in Fig. 1(a), the upper cover 10 is formed in a rectangular shape, and is provided with a pair of notches 10a spaced a certain distance apart in the front-to-rear direction. As shown in Fig. 1(a), the pair of notches 10a are formed in the shape of an elongated rectangle that penetrates in the up-down direction and is long in the left-to-right direction.
[0021] On the other hand, the lower cover 11 is provided at a position opposite the upper cover 10, and is formed in a rectangular shape of the same size as the upper cover 10. Like the upper cover 10, the lower cover 11 is also provided with a pair of notches 11a spaced a certain distance apart in the front-to-rear direction. As shown in FIG. 1(a), these pair of notches 11a are provided at positions opposite the pair of notches 10a described above, and are formed in an elongated rectangular shape that is approximately the same size as the pair of notches 10a, penetrates in the up-down direction, and is long in the left-to-right direction.
[0022] 1(a), the left cover 12 is formed in an upright shape and in the shape of an elongated rectangle that is long in the front-to-rear direction. The left cover 12 thus formed is formed to have the same length in the front-to-rear direction as the upper cover 10 and the lower cover 11. As shown in FIG. 1(a), the upper side 12a of the left cover 12 and the left side 10b of the upper cover 10 are integrally formed, and the lower side 12b of the left cover 12 and the left side 11b of the lower cover 11 are integrally formed.
[0023] Thus, by configuring the heat insulating cover 1 as described above, the inside is formed into a hollow main shape as shown in FIG. 1(a).
[0024] The heat insulating material 2 shown in FIG. 1(a) is made of glass fiber and is formed in a rectangular shape with six sides, including an upper surface 2a, a lower surface 2b, a left side surface 2c, a right side surface 2d, a front side surface 2e, and a rear side surface 2f. The heat insulating material 2 thus formed has a length in the front-to-rear direction that is approximately the same as the length of the upper cover 10 and the lower cover 11 shown in FIG. 1(a) in the front-to-rear direction, and a length in the left-to-right direction that is approximately the same as the length of the upper cover 10 and the lower cover 11 shown in FIG. 1(a). Furthermore, as shown in FIG. 1(a), the heat insulating material 2 thus formed has a pair of notches 2g spaced a certain distance apart in the front-to-rear direction. The pair of notches 2g are approximately the same size as the pair of notches 10a and the pair of notches 11a shown in FIG. 1(a), penetrate the heat insulating material in the up-down direction, and are formed in an elongated rectangular shape that is long in the left-to-right direction.
[0025] Thus, the heat insulating material 2 configured in this manner is sandwiched between the heat insulating material cover 1 as shown in Fig. 1(a), and is housed within the heat insulating material cover 1 as shown in Fig. 1(b). In this way, the heat insulating component 3 as shown in Fig. 1(b) is manufactured.
[0026] The heat insulating component 3 manufactured in this manner is used in industrial machinery, and is installed, for example, in an SCR device 100 as shown in Fig. 8. Specifically, the heat insulating component 3 can be installed in the SCR device 100 by fitting the pair of handles 100a into the pair of notches 10a, the pair of notches 11a, and the pair of notches 2g.
[0027] Incidentally, when fixing the heat insulating cover 1 in the position shown in Fig. 1(b), this heat insulating part 3 uses sewing thread or the like to attach and fix the heat insulating cover 1 to the heat insulating material 2. As a result, as shown in Fig. 1(b), the upper surface 2a of the heat insulating material 2 is covered by the upper cover 10 of the heat insulating material cover 1, the lower surface 2b of the heat insulating material 2 is covered by the lower cover 11 of the heat insulating material cover 1, and the left side surface 2c of the heat insulating material 2 is covered by the left cover 12 of the heat insulating material cover 1. In other words, the heat insulating material 2 is not entirely covered by the heat insulating material cover 1, and the right side surface 2d, front side surface 2e, and rear side surface 2f of the heat insulating material 2 are exposed to the outside.
[0028] Therefore, by doing this, the entire insulating material 2 is not covered as in the conventional case, and therefore manufacturing costs can be kept low. Furthermore, since the insulating material cover 1 does not need to be the same shape as the insulating material 2, manufacturing can be simplified. Furthermore, since the insulating material cover 1 does not cover the entire insulating material 2, it is easy to check for deterioration of the insulating material 2. Furthermore, if only a portion of the insulating material 2 is covered with the insulating material cover 1, scattering of glass fibers from the insulating material 2 can be reduced as in the conventional case.
[0029] Therefore, according to this embodiment, it is possible to easily manufacture the heat insulating cover and also to easily check for deterioration of the heat insulating material.
[0030] <Description of Modifications> The shapes and other features shown in this embodiment are merely examples, and various modifications and alterations are possible within the scope of the gist of the present invention as defined in the claims. For example, in this embodiment, the insulating cover 1 is attached to the insulating material 2 using sewing thread or the like to secure the insulating material cover 1 in the position shown in FIG. 1(b). However, any method of attachment may be used. For example, the insulating material cover 1 may be attached to the insulating material 2 using adhesive or the like, or hook-and-loop fasteners may be attached to the insulating material cover 1 and the insulating material 2. Alternatively, magnets may be attached to the insulating material cover 1 and the insulating material 2. As shown in FIG. 2, male or female snap buttons 13 may be provided on the insulating material cover 1 at regular intervals in the front-to-back direction, and female or male snap buttons 2h may be provided on the insulating material 2 at regular intervals in the front-to-back direction. In this manner, the insulating material cover 1 can be attached to the insulating material 2 by fitting the snap buttons 13 and the snap buttons 2h together.
[0031] 3, a pair of hook-shaped fasteners 14 may be provided on the heat insulating cover 1 in the front-to-rear direction, and a pair of female or male snap buttons 2i may be provided on the heat insulating material 2 in the front-to-rear direction to attach and fix the fasteners 14. In this way, the fasteners 14 can be attached and fixed by fitting male or female snap buttons (not shown) provided on the fasteners 14 into the snap buttons 2i. This allows the heat insulating material cover 1 to be attached and fixed to the heat insulating material 2. Note that when attaching and fixing the fasteners 14, any method may be used, such as hook-and-loop fasteners, magnets, or sewing with thread, without using snap buttons.
[0032] Also, as shown in FIG. 4, the heat insulating cover 1 may be attached and fixed to the heat insulating material 2 using a ring-shaped fastener 15. This fastener 15 can be formed into a rectangular ring shape by fitting male or female snap buttons 15a together, as shown in FIG. 4. Therefore, as shown in FIG. 4, the heat insulating material cover 1 and the heat insulating material 2 can be inserted into this fastener 15, and the male or female snap buttons 15a are fitted together to form a rectangular ring shape, thereby attaching and fixing the heat insulating material cover 1 to the heat insulating material 2. Note that, when forming the rectangular ring shape, any method may be used, such as hook-and-loop fasteners, magnets, or sewing with thread, without using snap buttons.
[0033] Therefore, the heat insulating cover 1 can be attached and fixed to the heat insulating material 2 in a variety of ways.
[0034] In addition, in this embodiment, the right side surface 2d, the front side surface 2e, and the rear side surface 2f of the heat insulating material 2 are exposed to the outside, that is, three of the six sides of the heat insulating material 2 are exposed to the outside, but this is not limiting, and two of the six sides of the heat insulating material 2 may be exposed to the outside. This point will be explained in detail with reference to Figure 5. Note that the same components as in Figure 1 are assigned the same reference numerals and explanations will be omitted.
[0035] As shown in FIG. 5(a), the heat insulating cover 1A is made of glass cloth or the like and is composed of an upper cover 10, a lower cover 11, a left cover 12, and a right cover 16A. As shown in FIG. 5(a), a plurality of mushroom-shaped insertion pieces 17A are provided at regular intervals in the front-to-rear direction on the right side 10c of the upper cover 10. As shown in FIG. 5(a), a right cover 16A is integrally provided on the right side 11c of the lower cover 11. As shown in FIG. 5(a), the right cover 16A is formed in an upright, elongated rectangular shape that is long in the front-to-rear direction and is the same size as the left cover 12. Furthermore, as shown in FIG. 5(a), the right cover 16A has a plurality of linear insertion holes 16Aa provided at regular intervals in the front-to-rear direction at approximately the center of the right cover 16A. Each of the insertion holes 16Aa corresponds to one of the insertion pieces 17A.
[0036] Thus, when covering the insulating material 2 with the insulating material cover 1A configured in this manner, first, the insulating material 2 is inserted into the insulating material cover 1A as shown in FIG. 5(b). In this state, by inserting the insertion piece 17A into the insertion hole 16Aa as shown in FIG. 5(b), the insulating material cover 1A is formed into a cylindrical shape as shown in FIG. 5(c), and the insulating material 2 is thereby sandwiched between the insulating material cover 1A. Therefore, the insulating material cover 1A can be attached and fixed to the insulating material 2. In this way, an insulating component 3A as shown in FIG. 5(c) is manufactured.
[0037] Thus, as shown in FIG. 5(c), the front side surface 2e and the rear side surface 2f of the heat insulating material 2 are exposed to the outside.
[0038] Therefore, even with this configuration, the entire insulating material 2 is not covered as in the past, which makes it possible to keep manufacturing costs low. Furthermore, since the insulating material cover 1A does not need to be the same shape as the insulating material 2, manufacturing can be simplified. Furthermore, since the insulating material cover 1A does not cover the entire insulating material 2, it is easy to check for deterioration of the insulating material 2. Furthermore, if only a portion of the insulating material 2 is covered with the insulating material cover 1A, scattering of glass fibers from the insulating material 2 can be reduced as in the past.
[0039] Therefore, this also makes it possible to easily manufacture the heat insulating cover and to easily check for deterioration of the heat insulating material.
[0040] Also, while Figure 5 shows an example in which the insertion piece 17A is inserted into the insertion hole 16Aa to form the insulating cover 1A into a cylindrical shape, various methods are possible for forming the insulating cover 1A into a cylindrical shape. For example, hook-and-loop fasteners may be provided in place of the insertion hole 16Aa and the insertion piece 17A, and the hook-and-loop fasteners may be attached to each other. Alternatively, magnets may be provided in place of the insertion hole 16Aa and the insertion piece 17A, and the magnets may be attached to each other. Alternatively, snap buttons as shown in Figure 2 may be provided, and the snap buttons may be fitted together.
[0041] Alternatively, a heat insulating cover 1B as shown in Fig. 6 may be used. This point will be specifically explained with reference to Fig. 6. Note that the same components as those in Fig. 1 are given the same reference numerals and explanations thereof will be omitted.
[0042] As shown in Fig. 6(a), the heat insulating cover 1B is made of glass cloth or the like and is composed of an upper cover 10, a lower cover 11, a left cover 12, and a right cover 18B. As shown in Fig. 6(a), the right cover 18B is integrally provided on the right side 10c of the upper cover 10. As shown in Fig. 6(a), this right cover 18B is formed in an upright shape, in the shape of an elongated rectangle that is long in the front-to-rear direction, and is formed to be the same size as the left cover 12.
[0043] Thus, when covering the thermal insulation material 2 with the thermal insulation cover 1B configured in this way, first the right cover 18B is sewn to the right side 11c of the lower cover 11 with sewing thread. As a result, the thermal insulation material cover 1B is formed into a cylindrical shape, as shown in FIG. 6(b). In this state, when the thermal insulation material 2 is inserted into the thermal insulation material cover 1B, as shown in FIG. 6(b), the thermal insulation material 2 is sandwiched between the thermal insulation material cover 1B. This allows the thermal insulation material cover 1B to be attached and fixed to the thermal insulation material 2, and an insulating component 3B as shown in FIG. 6(c) is produced.
[0044] Thus, as shown in FIG. 6(c), the front side surface 2e and the rear side surface 2f of the heat insulating material 2 are exposed to the outside.
[0045] Therefore, even with this configuration, the entire insulating material 2 is not covered as in the past, which makes it possible to keep manufacturing costs low. Furthermore, since the insulating material cover 1B does not need to be the same shape as the insulating material 2, manufacturing can be simplified. Furthermore, since the insulating material cover 1B does not cover the entire insulating material 2, it is easy to check for deterioration of the insulating material 2. Furthermore, if only a portion of the insulating material 2 is covered with the insulating material cover 1B, scattering of glass fibers from the insulating material 2 can be reduced as in the past.
[0046] Therefore, this also makes it possible to easily manufacture the heat insulating cover and to easily check for deterioration of the heat insulating material.
[0047] In addition, in the heat insulating cover 1B shown in Fig. 6, an example is shown in which the right cover 18B is sewn to the right side 11c of the lower cover 11 with sewing thread, but this is not limiting, and the heat insulating cover 1B may be formed in advance into a cylindrical shape as shown in Fig. 6(b). Also, as shown in Fig. 7, a chuck mechanism 18Ba may be provided in the front-to-rear direction at approximately the center of the right cover 18B.
[0048] Therefore, as explained above, the heat insulating covers 1A, 1B can be made cylindrical in various ways.
[0049] In addition, in this embodiment, two or three of the six faces of the heat insulating material 2 are exposed to the outside, but this is not limiting, and only the top face 2a and bottom face 2b of the heat insulating material 2 may be covered with a heat insulating material cover (not shown), leaving the four side faces exposed to the outside. Even in this case, the same effects as those described above can be obtained. [Explanation of symbols]
