Hereinafter, with reference to the accompanying drawings will be described the configuration of the pipe cover device according to an embodiment of the present invention.

Referring to FIG. 1, the pipe cover device 10 according to the present embodiment includes a first portion 100 and a second portion 200, and the first and second portions 100 and 200 are respectively a heating layer 110, The first heat insulating layers 120 and 220, the second heat insulating layers 130 and 230, the sound absorbing layers 150 and 250, and the outer jackets 170 and 270 are included.

Referring to FIG. 2, the first and second portions 100 and 200 are formed substantially symmetrically along the longitudinal direction of the pipe P, and each cross section is approximately circular. The first and second portions 100 and 200 are pivotally connected by one side to each other by the hinge 20 and the other side thereof are connected to each other by at least one pair of clamping units 30.

The pair of clamping units 30 includes a hook portion 31, a connecting ring 33, and a locking portion 35. The hook portion 31 is fixed to the first portion 100, the locking portion 35 is fixed to the second portion 200, in this case the connecting ring 33 is rotatably connected to the locking portion 35 do.

When the pipe cover device 10 is coupled to the pipe P, the first and second parts 100 and 200 surround the pipe P, and then the connecting ring 33 is hooked to the hook part 31 and locked. Pulling the part 35 toward the first part 100 connects the connecting ring 33 to the hook part 31 in a state having a predetermined elasticity. On the contrary, when the pipe cover device 10 is separated from the pipe P, the locking part 35 is pivoted toward the second part 200 so that the connecting ring 31 is separated from the hook part 35 and then the first and The second portions 100 and 200 are pivoted about the hinge 20 and separated from the pipe P that was wrapped.

The first and second portions 100 and 200 include a heating unit 110 that generates heat by receiving an external power source to insulate the pipe P. In addition, the first and second portions 100 and 200 may be configured to maintain the elevated temperature by the heating unit 110 or to prevent the temperature of the fluid itself from being affected by the external temperature, respectively. Insulating layers (130, 230), and the sound absorbing layer (150, 250) and the outer jacket (170, 270) for blocking the noise of the pipe (P). In this case, the heating layers 110, the first heat insulating layers 120 and 220, the second heat insulating layers 130 and 230, the sound absorbing layers 150 and 250, and the outer jackets 170 and 270 are stacked in order from the inside.

The heating layer 110 is formed in a substantially thin sheet shape and a heating wire (not shown) is arranged inside, and the outside is coated with a silicon layer (not shown). In this case, the heating wire may be made of carbon wire or chromium wire. In addition, the heating layer 110 has first and second code lines 191 and 193 connected to both sides thereof, respectively.

The male cord 192 is connected to the end of the first cord line 191 and the female plug 194 is connected to the end of the second cord line 193. In this case, the male plug 192 and the female plug 194 are connected to the male plug 192 and the female plug 194 of the pipe cover device 10 disposed adjacent to each other as shown in FIG. 2. Accordingly, the heating layer 110 of the plurality of pipe cover devices 10 continuously arranged in the pipe P may receive power from the outside to heat and heat the pipe P.

The first heat insulating layers 120 and 220 are in direct contact with the outer circumferential surface of the heating paste 110, and the material is made of aerogel. These aerogels are solid materials that are filled with gas instead of liquid in the gel and exhibit remarkable physical properties such as ultra low density, which effectively blocks convection so that air cannot circulate through the pores and thus has high thermal insulation performance. In addition, the advantages of aerogels are light weight, when transporting a high temperature fluid through the pipe (P) does not generate a separate toxic gas in direct contact with the pipe (P), low thermal conductivity. The use temperature of the first heat insulating layer (120, 220) is set to approximately -200 ℃ ~ 650 ℃ range.

The second heat insulating layers 130 and 230 are made of a high temperature composite heat insulating material which is carbon fiber or ceramic fiber, and when used together with the first heat insulating layers 120 and 220, the second heat insulating layers 130 and 230 may withstand thermal shock of about 1300 ° C. FIG. In this case, the second heat insulating layers 130 and 230 may of course be formed of a composite layer of carbon fiber and ceramic fiber.

When the second heat insulating layer (130,230) is used in conjunction with the first heat insulating layer (120,220) in double, it can maximize the heat insulating effect, such as withstanding thermal shock at very high temperature without causing toxic gas generation.

In this case, when the temperature of the pipe used is about 650 ° C. or less, the second heat insulating layers 130 and 230 may be omitted and only the first heat insulating layers 120 and 220 may be used. In addition, even when only the first heat insulation layers 120 and 220 are used, when the thickness of the first heat insulation layers 120 and 220 is further increased, the second heat insulation layers 130 and 230 may be used without the second heat insulation layers 130 and 230.

The sound absorbing layers 150 and 250 surround the second heat insulating layers 130 and 230, and the material is made of aluminum form. Aluminum foam is a new material manufactured by special foaming process using additive material (eg waste titanium) after melting aluminum ingot, for example. It is composed of independent porous pores and thin-film cells, so it has high sound absorption in all frequency bands. Has characteristics. In addition, the sound absorbing layers 150 and 250 may be made of aluminum foam as well as lead foam.

In this case, the sound absorbing layers 150 and 250 may be made of any one of lead foam, foam glass, airgel foam, and urethane foam in addition to aluminum foam.

The outer jackets 170 and 270 surround the sound absorbing layers 150 and 250 and are disposed at the outermost sides of the first and second portions 100 and 200 to heat the inner heating layer 110, the first and second heat insulating layers 120, 220, 130 and 230, and the sound absorbing layer. Protect 150,250 from external shocks.

The outer jackets 170 and 270 are made of metal, for example, stainless steel or aluminum so as to secure a predetermined rigidity. In this case, the outer jackets 170 and 270 may of course use a glass fiber sheet (not shown) having a predetermined thickness in addition to the metal material.

Referring to FIG. 4, the outer jackets 170 and 270 are formed with an extension 171 along the side end of the outer jacket 170 of the first portion 100 in which the locking part 35 of the clamping unit 30 is installed. The extension 171 partially overlaps outside the outer jacket 270 of the opposite second portion 200 when coupling the first and second portions 100, 200. Accordingly, the parts in contact with each other of the first and second parts 100 and 200 may be shielded from being exposed to the outside so that heat loss of the fluid passing through the pipe P may be blocked.

Referring to FIG. 5, as another embodiment for blocking heat loss of the fluid passing through the pipe P as described above, the heating layer 110 and the first heat insulating layers 120 and 220 may be formed in the first and second portions, respectively. By rotating the same angle along the circumferential direction of the (100, 200), one end of the first heat insulating layer (120, 220) to protrude a predetermined distance (A1) from one side end of the second heat insulating layer (130,230). In this case, the other end of the heating layer 110 and the first heat insulating layers 120 and 220 enters inwardly from the other end of the second heat insulating layers 130 and 230 by a predetermined distance A1.

As described above, when the heating layer 110 and the first heat insulation layers 120 and 220 are disposed, the first and second heat insulation layers 120 and 220 may be in contact with each other by combining the first and second portions 100 and 200 to cover the pipe P. The cross-sections are arranged to be offset from the same line of the end surfaces of the second heat insulation layers 130 and 230 and the sound absorbing layers 150 and 250, which overlap each other, and overlap the contact portions of the second heat insulation layers 130 and 230. Accordingly, the contact portion between the first and second portions 100 and 200 causing heat loss may be covered.

Referring to FIG. 6, as another embodiment for preventing heat loss, the heating layer 110, the first heat insulating layer 120 and 220, and the second heat insulating layer 130 and 230 may be formed of the first and second portions 100 and 200, respectively. It is also possible to form the end of the first and second heat insulating layers (120, 220; 130, 230) to protrude by a predetermined distance (A2, A3), respectively, by rotating at a predetermined angle along the circumferential direction.

In this case, when the first and second portions 100 and 200 are coupled to each other, the second heat insulation layers 130 and 230 overlap the first heat insulation layers 120 and 220, and the sound absorbing layers 150 and 250 overlap the second heat insulation layers 130 and 230. In addition, the contact portion between the first and second portions 100 and 200 causing heat loss may be doubled.

On the other hand, although not shown in the drawings in the present embodiment, the outer jacket (170,270) when the first and second portion (100,200) is coupled by rotating the sound absorbing layer (150,250) by a predetermined angle in the circumferential direction of the cover device 10 It is also possible to configure to overlap the ends in contact with each other. In addition, of course, the first and second heat insulating layers 120, 220, 130, and 230 may be sequentially rotated by a predetermined angle in the circumferential direction of the cover device 10.

Referring to FIG. 7, the pipe cover devices 10a and 10b of the present embodiment may be formed in a predetermined length to cover the pipe P using a plurality of pipe cover devices. In this case, when each cover device (10a, 10b) is coupled to the pipe, the heat loss may occur through this part because the portion that the cover device (10a, 10b) is in contact with each other is not completely closed.

In this way, in order to prevent heat loss occurring between the cover devices 10a and 10b, the heating layer 110 of the cover devices 10a and 10b is moved along the length direction of the cover devices 10a and 10b. The front end of the heating layer 110 is disposed to protrude a predetermined length (L1) from the front end of the first heat insulating layer (120,220). As such, when the heating layers 110 protrude from the first and second portions 100 and 200 by the same length L1, when the cover devices 10a and 10b are sequentially coupled to the pipe P, the heating layer ( 110 may overlap the first heat insulating layers 120 and 220 to prevent heat loss from being generated between the cover devices 10a and 10b.

Referring to FIG. 8, similarly to the method of arranging the heating layer 110, the heating layers 110 and the first heat insulating layers 120 and 220 are sequentially protruded in the same direction by a predetermined length (L2 and L3), respectively. It is possible to prevent the heat loss occurring in the portion in contact between the (10a, 10b).

Similarly, referring to FIG. 9, the heating layers 110, the first heat insulating layers 120 and 220, and the second heat insulating layers 130 and 230 are sequentially protruded in the same direction by predetermined lengths L4, L5, and L6, respectively, to cover each of the cover devices 10a,. It is possible to prevent heat loss occurring at the part in contact with each other.

On the other hand, although not shown in the drawings in this embodiment, the sound-absorbing layers 150, 250 are projected by the same length in the longitudinal direction of the cover device (10a, 10b), respectively, overlapping the ends that each cover device (10a, 10b) contact each other It is also possible to configure to.

Furthermore, the cover devices 10, 10a, and 10b of the present embodiment are not shown in the drawings, but at least one of the heating layer 110, the first heat insulating layer 120, 220, the second heat insulating layer 130, 230, and the sound absorbing layer 150, 250 may be used. It is of course also possible to use the cover devices 10, 10a and 10b by simultaneously protruding and arranging them in the circumferential direction and the longitudinal direction.

Referring to FIG. 10, the hinge 20 (see FIG. 1) is omitted so that the first and second portions 100 and 200 can be completely separated, and the clamp unit 30a is installed at this portion. Accordingly, the pipe cover device 10c may be coupled to the pipe P through the clamp units 30 and 30a installed at both ends of the first and second parts 100 and 200 in contact with each other.

As shown in FIG. 4, the mutually separable pipe cover device 10c has an extension portion (not shown) so as to overlap the longitudinal side ends of the respective outer jackets 170 and 270 of the first and second portions 100 and 200. Can be formed.

5 to 9, the cover device 10c may cover at least one of the heating layer 110, the first heat insulation layer 120 and 220, the second heat insulation layer 130 and 230, and the sound absorption layer 150 and 250. Protruding arrangement in the circumferential direction or the longitudinal direction of 10c), or protruding arrangement in the circumferential direction and the longitudinal direction can be used.

As described above, in the present invention, the heating layer 110 is electrically connected to each other via the adjacent pipe cover device 10 and the male and female plugs 192 and 194 of the first and second cord lines 191 and 193. By providing a stable electricity can be supplied to the heating layer 110 without a short circuit between each pipe cover device (10). Accordingly, through the heating layer 110 can be applied to the pipe (P) insulation function stably.

In addition, the present invention can realize the optimum heat insulating structure by using the second heat insulating layer (130,230) made of carbon fiber or ceramic fiber together with the first heat insulating layer (120,220) made of airgel. Furthermore, the sound absorbing layers 150 and 250 made of aluminum foam can effectively absorb the noise in the pipe P generated by the transfer of the fluid.

Meanwhile, the cover device of the present invention has been described with an example in which the first and second parts 100 and 200 are coupled to each other by the clamping units 30 and 30a, but the present invention is not limited thereto and the first and second parts 100 and 200 are not limited thereto. It is of course also possible to combine the first and second portions 100 and 200 by a wrapping band (not shown). In this case, it is preferable that the band is made of a material having elasticity or provided with a conventional connection and separation structure such as a buckle structure provided in a conventional waistband.

In the present embodiment, the heating layer 110 is formed as a single sheet. However, the heating layer 110 is not limited thereto and may be divided into two pieces so that the heating layer 110 may be divided into the first and second portions 100 and 200, respectively. In this case, it is preferable to further prepare a pair of cord wires and male / female plugs so that power can be applied to the heating layer divided into two pieces.

Referring to FIG. 11, the first and second parts 100 and 200 have a structure that is completely separated from each other as shown in FIG. 10. In this case, the first and second portions 100 and 200 illustrated in FIG. 11 are different from the first and second portions 100 and 200 illustrated in FIG. 10.

That is, the clamping units 30b and 30c of the first and second portions 100 and 200 are fitted to each other and include a plurality of coupling hooks 177 and 277 and coupling holes 179 and 279. The plurality of coupling hooks 177 and 277 and the coupling holes 179 and 279 are disposed in two rows at edges 173, 273 and 274 which respectively surround the ends of the first insulating layer 110 and 210, the second insulating layer 130 and 230 and the sound absorbing layers 150 and 250. .

In this case, the edge portions 173 and 273 formed at one end of the first and second portions 100 and 200 are coupled to the hooks 177 and 277 and the coupling holes 179 and 279 to the second column C2 adjacent to the first column C1, respectively. The at least one pair of coupling hooks 177 and 277 and the coupling holes 179 and 279 arranged in the first row C1 are opposite to the coupling hooks 177 and 277 and the coupling holes 179 and 279 arranged in the second row C2. Is placed. In this case, the edge portions 174 and 274 formed at the other ends of the first and second portions 100 and 200 are coupled to the hooks 177 and 277 and the coupling holes formed at the edge portions 173 and 273 at one end of the first and second portions 100 and 200. 179, 279).

This arrangement takes into account that both the first and second portions 100 and 200 have the same structure. That is, when the coupling hooks 177 and 277 are inserted into the coupling holes 179 and 279 while the concave portions face each other to mutually couple the first and second portions 100 and 200, the edge portions 173 and 174 of the first portion 100 are inserted. ) And the coupling hooks 177 and 277 and the coupling holes 179 and 279 formed at the edge portions 273 and 274 of the second portion 200 corresponding thereto are coupled to each other.

On the other hand, one (173, 273) of the edge portion (173, ® 273, 274) is formed extending from one end of the outer jacket (170, 270) is bent, the other one (174, 274) of the outer jacket (170, 270) through various bonding methods such as welding It may be coupled to the other end.

In addition, the edge parts 173, 273, and 274 may have the first and second rows formed stepped with each other, thereby preventing heat loss from occurring due to a gap between the first and second parts 100 and 200.

Furthermore, the other ends of the outer jacket (170.270) are formed with extensions (171, 271), respectively, and when the pipe (P) is wrapped with the first and second portions (100,200), respectively, at one end of the opposite outer jacket (170,270). The gap between the first and second portions 100 and 200 which overlap and cause heat loss may be doubled.

Referring to FIG. 12, the plurality of coupling hooks 177 and the coupling holes 179 formed at the edge portions 173 and 174 of the first portion 100 have the same length L, respectively, and the edge portions 173 and 174. The setting positions of the coupling hook 177 and the coupling hole 179 which are respectively disposed adjacent to the front end portion F and the rear end portion R are slightly different.

That is, the coupling hook 177 and the coupling hole 179 adjacent to the tip portion F of the edge portions 173 and 174 are spaced apart from the tip portion F by the first length α, and the rear ends of the edge portions 173 and 174 are separated. The engagement hook 177 and the engagement hole 179 adjacent to R are spaced apart from the rear end R by a second length L + α longer than the first length α. This is to prevent a step from occurring in the line / rear end portions F and R of the first and second portions 100 and 200 when the first and second portions 100 and 200 are coupled to each other.

In this case, the positions of the plurality of coupling hooks 277 and the coupling holes 279 formed at the edge portions 273 and 274 of the second portion 200 are also set in the same manner as the first portion 100 described above.

Referring to FIG. 13, the coupling hook 177 of the first portion 100 is bent a predetermined height in the longitudinal direction of the first portion 100. The coupling hole 279 of the second portion 200 corresponding to the coupling hook 177 is formed with a guide portion 279a for guiding in the coupling direction after the coupling hook 177 is inserted into the coupling hole 279. .

11 to 13 illustrate an example in which coupling hooks 177 and 277 and coupling holes 179 and 279 formed at edges 173, 273 and 274 are arranged in two rows C1 and C2, respectively, but are not limited thereto.

That is, as shown in FIG. 14, the edge portions 173, 273, 274 are formed in a plane without multiple stage bending, and the coupling hooks 177, 277 and the coupling holes 179, 279 are arranged in one row C3 at the edge portions 173, 273, 274, respectively. It is also possible to arrange. In this case, the first and second portions 100 and 200 illustrated in FIG. 12 will not be described for the same configuration as the first and second portions 100 and 200 illustrated in FIG. 9.
