[0032] The utility model provides an insulation door, which can be installed in automated production equipment such as ovens. The following will take the installation of the insulation door in an oven as an example for introduction. Figure 1 A preferred embodiment of the heat insulation door provided by the utility model is shown. Figure 2 Shows the installation Figure 1 A preferred embodiment of an oven with a middle insulated door.

[0033] See also Figure 1 and Figure 2 In this embodiment, the heat-insulating door 100 includes a first door body 1, a second door body 2 and a heat-insulating pad 3. The first door body 1 is located outside the box body 200, and the first door body 1 is sealed at the opening of the box body 200 (not shown in the figure); the second door body 2 enters the box body 200 from the opening of the box body 200; the heat-insulating pad 3 is arranged between the first door body 1 and the second door body 2, and is used to separate the first door body 1 and the second door body 2.

[0034] Specifically, an opening is provided on the wall of the box body 200, and the opening of the box body 200 communicates with the inside and outside of the box body 200. During the normal operation and production process of the oven 1000, the outside of the box body 200 is a low-temperature area, and the inside of the box body 200 is a high-temperature area. The integral heat-insulating door 100 is composed of a first door body 1 and a second door body 2. The first door body 1 is located outside the box body 200, and the first door body 1 is in the low-temperature area. The first door body 1 can completely cover the opening of the box body 200. The second door body 2 can enter the box body 200 from the opening of the box body 200, and the second door body 2 is located inside the box body 200, and the second door body 2 is in the high-temperature area.

[0035] The heat insulation pad 3 is arranged between the first door body 1 and the second door body 2 at intervals, so that the first door body 1 and the second door body 2 do not contact each other, and the second door body 2 in the high temperature area and the first door body 1 in the low temperature area can be effectively isolated, thereby effectively reducing the surface temperature of the box body 200, reducing the transfer and loss of heat, and the heat in the high temperature area is effectively isolated, which can greatly reduce the risk of scalding the operator and make the working environment safer. Among them, the heat insulation pad 3 can be heat insulation cotton or a fire blanket, and the specific setting method of the heat insulation pad 3 will be further introduced below.

[0036] An insulation pad 3 is provided between the first door body 1 and the second door body 2 of the thermal insulation door 100 of the utility model. The insulation pad 3 can effectively isolate the second door body 2 in the high temperature area and the first door body 1 in the low temperature area, thereby effectively reducing the surface temperature of the box body 200, reducing the transfer and loss of heat, and the heat in the high temperature area is effectively isolated, which can greatly reduce the risk of scalding the operator and make the working environment safer.

[0037] The first door body 1 is usually a closed metal door panel such as a stainless steel door panel, and the interior of the first door body 1 is filled with sufficient insulation materials such as insulation cotton. Figure 1 In this embodiment, a first heat-insulating layer 12 is filled in the first door body 1 .

[0038] Specifically, the first door body 1 is an independent, closed part, and the interior of the first door body 1 is filled with insulation materials such as insulation cotton to form a first insulation layer 12, so that the first door body 1 has a good insulation effect. The first insulation layer 12 is filled before the first door body 1 is bent and sealed, and the filling is ensured to be full and compact, so as to ensure the good insulation performance of the first door body 1.

[0039] Similarly, the second door body 2 is usually a closed metal door panel such as a stainless steel door panel, and the interior of the second door body 2 is filled with sufficient insulation materials such as insulation cotton. Figure 1 In this embodiment, a second thermal insulation layer 21 is filled in the second door body 2 .

[0040] Specifically, the second door body 2 is an independent, closed part, and the interior of the second door body 2 is filled with insulation materials such as insulation cotton to form a second insulation layer 21, so that the second door body 2 has a good insulation effect. The second insulation layer 21 is filled before the second door body 2 is bent and sealed, and the filling is ensured to be full and compact, so as to ensure the good insulation performance of the second door body 2.

[0041] Optionally, the first insulation layer 12 and the second insulation layer 21 are made of cotton-like glass fiber wool, which can be formed into any shape as needed, so that it is easy to be stuffed into the first door body 1 and the second door body 2 for artificial filling.

[0042] The shapes of the first door body 1 and the second door body 2 are usually compatible with the shape of the opening of the box body 200, and the area of ​​the first door body 1 is larger than the area of ​​the opening of the box body 200, so that the first door body 1 can cover the opening of the box body 200, and the area of ​​the second door body 2 is less than or equal to the area of ​​the opening of the box body 200, so that the second door body 2 can enter the box body 200 from the opening of the box body 200. The following will take the first door body 1, the second door body 2 and the opening of the box body 200 as an example.

[0043] The shape of the heat insulation pad 3 is usually compatible with the shape of the second door body 2, and the area size of the heat insulation pad 3 and the second door body 2 can be set according to actual conditions. Figure 1 In this embodiment, the area of ​​the thermal insulation pad 3 is equal to the area of ​​the second door body 2. In this way, the thermal insulation pad 3 can completely cover the surface of the second door body 2 close to the first door body 1, so that the thermal insulation pad 3 can completely and effectively isolate the second door body 2 in the high temperature area and the first door body 1 in the low temperature area. In other embodiments, the area of ​​the thermal insulation pad 3 is smaller than the area of ​​the second door body 2, but greater than or equal to the area of ​​the first door body 1, so as to fully reduce the area of ​​the thermal insulation pad 3 while achieving the thermal insulation function, thereby reducing costs. Furthermore, the area of ​​the thermal insulation pad 3 is larger than the area of ​​the opening to ensure the sealing of the box body 200.

[0044] Optionally, see Figure 1 In this embodiment, the heat insulation door 100 further includes a fixing member 4, which is disposed between the first door body 1 and the second door body 2, so as to limit the deformation amount of the heat insulation pad 3 in the direction from the second door body 2 to the first door body 1 through the fixing member 4.

[0045] Specifically, the thermal insulation pad 3 is clamped and fixed between the first door body 1 and the second door body 2, and a fixing member 4 is added between the first door body 1 and the second door body 2. The fixing member 4 can limit the distance between the first door body 1 and the second door body 2, thereby protecting the thermal insulation pad 3 and avoiding the problem of the thermal insulation pad 3 being squeezed, deformed and damaged.

[0046] Among them, a plurality of fixing members 4 are usually arranged at intervals along the circumference of the thermal insulation pad 3, so that the fixing members 4 can better protect the thermal insulation pad 3.

[0047] Optionally, see Figure 1 In the present embodiment, a gap is reserved between the fixing member 4 and the second door body 2 .

[0048] In particular, the thickness of the fixing member 4 is the dimension of the fixing member 4 in the direction from the second door body 2 to the first door body 1, and the thickness of the fixing member 4 is smaller than the spacing between the first door body 1 and the second door body 2, so that a gap can be reserved between the fixing member 4 and the second door body 2, so that the heat on the second door body 2 can be prevented from being transferred to the first door body 1 through the fixing member 4. And the gap between the fixing member 4 and the second door body 2 is smaller than the minimum gap at which the heat insulation pad 3 is damaged by extrusion deformation.

[0049] Optionally, see Figure 1 In this embodiment, a receiving hole 31 is provided on the surface of the thermal insulation pad 3 close to the second door body 2 so as to penetrate the fixing member 4 , and the fixing member 4 is located in the receiving hole 31 .

[0050] Specifically, the shape of the fixing part 4 is usually compatible with the shape of the receiving hole 31. The fixing part 4 is installed in the receiving hole 31 of the second door body 2, so that the fixing part 4 is embedded on the thermal insulation pad 3 and installed together between the first door body 1 and the second door body 2. In this way, the fixing part 4 can be installed and positioned between the first door body 1 and the second door body 2.

[0051] For example, the thermal insulation pad 3 is a flat plate of aerogel glass fiber wool with a certain hardness. The outer dimensions of the thermal insulation pad 3 are consistent with the outer dimensions of the second door body 2 . The thermal insulation pad 3 is provided with a receiving hole 31 on which the fixing part 4 is installed.

[0052] For further information, see Figure 1In this embodiment, a screw connection 5 is installed on the second door body 2 corresponding to the fixing member 4. The fixing member 4 is a fixing ring mounted on the screw connection 5. The tail of the screw connection 5 passes through the second door body 2 and the fixing member 4 in sequence and is threadedly connected to the first door body 1.

[0053] Specifically, the fixing member 4 is a flat cover, and screw mounting holes are provided on the fixing member 4 and the second door body 2 . The inner diameter of the fixing member 4 is larger than the outer diameter of the screw member 5 , and the outer diameter of the fixing member 4 is smaller than the aperture of the accommodating hole 31 on the thermal insulation pad 3 .

[0054] The screw connector 5 can be installed on the second door body 2 from the side of the second door body 2 away from the first door body 1, so that the first door body 1, the second door body 2 and the thermal insulation pad 3 are locked and fixed by the screw connector 5, and a fixing part 4 is added between the first door body 1 and the second door body 2. According to the different pressures when the screw connector 5 is locked, the gap between the fixing part 4 and the second door body 2 is smaller than the minimum gap that the thermal insulation pad 3 is squeezed out, deformed and damaged under the pressure. The thermal insulation pad 3 is protected by the fixing part 4, and the locking of the screw connector 5 is also limited to avoid damage to the thermal insulation pad 3 due to excessive tightening of the screw connector 5.

[0055] Among them, see Figure 1 The screw connection member 5 may be a bolt, and a spring plate 6 and a flat washer 7 are installed on the screw connection member 5 . The first door body 1 and the second door body 2 are locked by the screw connection member 5 , the spring plate 6 and the flat washer 7 .

[0056] When the door panel of the heat insulation door 100 has a large area, after the heat insulation material is inserted, the weight of the entire heat insulation door 100 will be large, which may cause a problem that one person cannot disassemble and assemble it, which is extremely inconvenient and unsafe for the operator. The first door body 1, the second door body 2, and the heat insulation pad 3 are detachably connected by the screw connection 5, and the entire heat insulation door 100 structure is disassembled into a split assembly structure. The heat insulation door 100 can be disassembled during the assembly and disassembly process, which is more convenient.

[0057] Optionally, see Figure 1 In this embodiment, a handle 13 is installed on the surface of the first door body 1 away from the second door body 2. By providing the handle 13 on the first door body 1, it is convenient for the operator to disassemble and assemble the heat insulation door 100. The handle 13 is installed before the first door body 1 is bent and sealed, and is welded on the inside to ensure its firmness.

[0058] The handle 13 may be a foldable structure, for example, the handle 13 is an N-shaped handle, and includes two mounting ends spaced apart from each other. Both mounting ends of the handle 13 can be rotatably disposed on the first door body 1 along an axis in the vertical direction, so that the handle 13 can be flipped and folded. The mounting end of the handle 13 has a thread, and can be locked on the surface of the first door body 1 away from the second door body 2 with a nut provided therewith.

[0059] When the thermal insulation pad 3 is a fire blanket, since the fire blanket will not cause crystal displacement due to external pressure, a fixing member 4 may be provided between the first door body 1 and the second door body 2 or not according to actual conditions. Optionally, in this embodiment, a screw connection 5 is installed on the surface of the second door body 2 away from the first door body 1, and the tail of the screw connection 5 passes through the second door body 2 and the thermal insulation pad 3 in sequence and is threadedly connected to the first door body 1. That is, the thermal insulation pad 3 is not provided with a fixing member 4 corresponding to the screw connection 5, and the screw connection 5 directly passes through the thermal insulation pad 3.

[0060] The first door body 1 is provided with a threaded hole corresponding to the screw connection member 5. The specific arrangement of the threaded hole on the first door body 1 can be set according to actual conditions. Figure 1 In this embodiment, a screw sleeve 11 is provided on the inner surface of the shell wall of the first door body 1 close to the second door body 2 corresponding to the screw connection member 5, so that the first door body 1 is threadedly connected to the screw connection member 5 through the screw sleeve 11. The screw sleeve 11 is embedded in the first door body 1, and the screw sleeve 11 is installed and welded before the first door body 1 is bent and sealed, so as to be threadedly connected to the screw connection member 5 through the screw sleeve 11.

[0061] For further information, see Figure 1 In this embodiment, the first thermal insulation layer 12 covers the threaded sleeve 11 .

[0062] Specifically, the screw sleeve 11 is embedded in the first insulation layer 12, and the screw sleeve 11 is surrounded by insulation materials. After the heat is transferred to the screw sleeve 11 through the screw connector 5, it will be isolated by the first insulation layer 12 in the first door body 1 and will no longer be transferred to the outer surface of the first door body 1.

[0063] Optionally, see Figure 1 In this embodiment, a sealing gasket 8 is provided on the surface of the first door body 1 close to the second door body 2 , and the sealing gasket 8 is clamped between the first door body 1 and the outer box wall of the box body 200 .

[0064] Specifically, the first door body 1 is fixedly connected to the outer box wall of the box body 200 by bolts, and the sealing gasket 8 is made of high-temperature resistant silicone rubber. The sealing gasket 8 is provided with bolt mounting holes for the bolts to pass through.

[0065] During the normal operation of the oven 1000, the heat insulation door 100 is installed on the oven 1000, and the first door body 1 and the box body 200 are well sealed by the sealing pad 8. The side close to the box body 200 is a high-temperature area, and the other side is a low-temperature operation area. The heat transferred from the high-temperature area to the screw connection 5 is isolated by the first insulation layer 12 in the first door body 1, and the heat transferred through the second door body 2 is isolated by the heat insulation pad 3. Due to the gap between the fixing member 4 and the second door body 2, the heat will not be transferred to the fixing member 4 through the second door body 2, nor will it be further transferred to the low-temperature area.

[0066] The utility model also provides an oven, which may be a tunnel oven, etc. The oven includes an insulating door. Since the insulating door adopts the technical solution of the above embodiment, it has the beneficial effects brought by the technical solution of the above embodiment. Figure 2 A preferred embodiment of the oven provided by the utility model is shown.

[0067] Optionally, see Figure 2 In this embodiment, the oven 1000 includes a box body 200, and the box body 200 is provided with an opening; the heat-insulating door 100 is arranged at the opening.

[0068] Optionally, see Figure 2 In this embodiment, a preheating module 300 , a heating module 400 , and a cooling module 500 are disposed on the box body 200 , and an insulating door 100 is installed on at least one of the preheating module 300 , the heating module 400 , and the cooling module 500 .

[0069] Specifically, the preheating module 300, the heating module 400, and the cooling module 500 are all equipped with the heat insulation door 100. For example, the heating module 400 is provided with an opening for replacing the high efficiency filter, and the heat insulation door 100 is installed at the opening.

[0070] The above are only preferred embodiments of the present invention, and do not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the present invention.
