Description

Technical Field

[0001] The embodiments of the present application relate to the field of thermal insulation structures, and in particular to a connected thermal insulation structure and thermal insulation doors and windows. Background Art

[0002] The electrode coating process is the core link in the electrode production process. Pole coating refers to the process of coating the evenly stirred slurry on the surface of the current collector and drying the organic solvent in the slurry.

[0003] The drying operation during the electrode coating can usually be carried out in an oven. In the related art, the oven includes an insulated door window, which can reduce the heat exchange between the inside and outside of the oven. The insulated door window includes an inner sheet metal and an outer sheet metal, which are arranged in sequence from the inside of the oven to the outside of the oven, and the inner sheet metal and the outer sheet metal are usually connected by screws.

[0004] However, during the heating and drying process, a high temperature environment is formed inside the oven, and the inner sheet metal is heated up due to contact with the high temperature environment. At this time, the screws are affected by the high temperature environment inside the oven and the high temperature of the inner sheet metal, and the temperature of the screws increases. When the temperature of the screws themselves is high, the screws are likely to transfer heat to the outer sheet metal, which in turn causes the temperature of the outer sheet metal to be higher than normal temperature, making it difficult for the insulation doors and windows to achieve the corresponding insulation effect. Utility Model Content

[0005] The purpose of the utility model is to provide a connecting insulation structure and its insulation door and window, which can reduce the accumulation of heat at the connecting piece and reduce the heat transfer between the connecting piece and the second sheet metal and the third sheet metal, which is beneficial to improve the insulation capacity of the connecting insulation structure.

[0006] In a first aspect, a connection and heat insulation structure of the utility model comprises:

[0007] First Sheet Metal;

[0008] A heat-insulating component is connected, comprising a second sheet metal and a third sheet metal arranged in sequence from the inside of the oven to the outside of the oven; and a connecting piece, the connecting piece is used to connect the second sheet metal and the third sheet metal, and the connecting piece is staggered with the first sheet metal; an inner heat-insulating pad is arranged between the connecting piece and the second sheet metal, and an outer heat-insulating pad is arranged between the connecting piece and the third sheet metal.

[0009] In some embodiments, the second sheet metal and the connecting member are respectively spaced apart from the first sheet metal.

[0010] In some embodiments, an external heat insulation board is disposed between the second sheet metal and the third sheet metal.

[0011] In some embodiments, the connector includes:

[0012] A bolt, wherein the bolt passes through the second sheet metal, the outer insulation board, and the third sheet metal in sequence, and the inner insulation pad is located between the bolt and the second sheet metal;

[0013] A nut is threadedly connected to the bolt, and the external thermal insulation pad is located between the nut and the third sheet metal.

[0014] In some embodiments, the inner thermal insulation pad and the outer thermal insulation pad are both Teflon gaskets.

[0015] In some embodiments, the second sheet metal includes a bending section, the bending section is arranged around one side of the outer insulation board, and the bending section is spaced apart from the third sheet metal.

[0016] Furthermore, the distance between the bending section and the third sheet metal is 4 to 10 mm.

[0017] In a second aspect, an insulating door and window of the utility model comprises a door frame and a connecting insulating structure as described above;

[0018] Wherein, a connection heat insulation area is formed on one side of the door frame, and the connection heat insulation structure is arranged in the connection heat insulation area.

[0019] In some embodiments, the door frame and the connecting insulation assembly are spaced apart.

[0020] Furthermore, an inner heat insulation board is provided between the door frame and the first sheet metal.

[0021] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0022] The utility model provides a connection heat insulation structure, in which the first sheet metal is close to the heat source and directly contacts the heat source, resulting in an increase in temperature. At this time, the heat at the first sheet metal is transferred to the third sheet metal through the second sheet metal and the connecting piece, respectively. The connecting piece and the first sheet metal are staggered, and the heat at the first sheet metal is difficult to be transferred to the connecting piece through heat dissipation, which can reduce the situation where the temperature of the connecting piece itself is high. When the heat at the first sheet metal is transferred to the second sheet metal, the connecting piece forms a heat isolation between the connecting piece and the second sheet metal through the setting of the inner heat insulation pad, which can reduce the heat exchange between the second sheet metal and the connecting piece; when the heat at the connecting piece is transferred to the third sheet metal, the connecting piece forms a heat isolation between the connecting piece and the third sheet metal through the setting of the outer heat insulation pad, which can reduce the heat exchange between the connecting piece and the third sheet metal. At this time, the temperature of the connecting piece itself is reduced and it is difficult for the connecting piece to transfer the heat inside the oven to the third sheet metal, which is conducive to improving the insulation effect between the first sheet metal and the third sheet metal.

[0023] The utility model provides an insulating door window, in which the heat at the first sheet metal is difficult to transfer to the third sheet metal, which can reduce the temperature change outside the oven so that a suitable temperature difference can be formed between the inside and the outside of the oven, which is beneficial to ensure the coating effect of the electrode.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. The described implementation is a part of the implementation of the utility model, not all of the implementations.

[0030] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0031] Embodiment 1:

[0032] The utility model discloses a connection heat insulation structure which can be used in an oven to effectively insulate the drying operation during electrode coating.

[0033] Reference Figure 1The utility model provides a connection heat insulation structure, including a first sheet metal 1, which is specifically an L-shaped sheet metal. The first sheet metal 1 is in direct contact with the high temperature environment inside the oven. At this time, the first sheet metal 1 transfers heat to the outside of the oven as a heat source. A connection heat insulation component 2 is provided on the side of the first sheet metal 1 away from the inside of the oven. The connection heat insulation component 2 includes a second sheet metal 21 and a third sheet metal 22. The second sheet metal 21 and the third sheet metal 22 are arranged in sequence from the inside of the oven to the outside of the oven.

[0034] In a preferred embodiment, an outer heat insulation board 24 is provided between the third sheet metal 22 and the second sheet metal 21. Specifically, the outer heat insulation board 24 can be a flame retardant heat insulation board, wherein the thermal conductivity of the outer heat insulation board 24 is 0.05-0.5W / (m﹒K), the specific heat capacity is 400-1000J / Kg, and the density is 0.5-2.0g / cm 3 The outer heat insulation board 24 can block the heat transfer between the second sheet metal 21 and the third sheet metal. It can be understood that this is not a specific limitation on the outer heat insulation board 24, and technicians in the relevant field can replace or improve it on this basis.

[0035] A connector 23 is provided between the second sheet metal 21 and the third sheet metal 22, wherein the connector 23 is offset from the first sheet metal 1, and the connector 23 is not provided corresponding to the first sheet metal 1, so that the heat transfer path between the first sheet metal 1 and the connector 23 is extended, and the heat radiation at the first sheet metal 1 is difficult to be directly transferred to the connection, so as to reduce the heat transfer between the first sheet metal 1 and the connector 23.

[0036] The connector 23 connects the second sheet metal 21, the outer heat insulation board 24 and the third sheet metal 22. An inner heat insulation pad 231 is placed between the connector 23 and the second sheet metal 21 to block heat transfer. Specifically, the inner heat insulation pad 231 is preferably, but not limited to, a Teflon gasket. An outer heat insulation pad 232 is arranged between the connector 23 and the third sheet metal 22 to block heat transfer. Specifically, the outer heat insulation pad 232 is preferably, but not limited to, a Teflon gasket. The Teflon gasket is resistant to high temperature and corrosion, which is conducive to improving the connection stability between the second sheet metal 21 and the third sheet metal 22, and is conducive to reducing the heat transfer between the second sheet metal 21 and the connector 23, and between the connector 23 and the third sheet metal 22.

[0037] The first sheet metal 1 is in contact with the high temperature environment, and the first sheet metal 1 absorbs heat and the temperature rises. At this time, the first sheet metal 1 acts as a hot structure, and the connection insulation component 2 acts as a cold structure. There is a temperature difference between the first sheet metal 1 and the connection insulation component 2, and heat transfer occurs.

[0038] The heat at the first sheet metal 1 is transferred to the third sheet metal 22 through the second sheet metal 21 and the connector 23 in turn. On the heat transfer path, the second sheet metal 21 and the connector 23 are thermally isolated by the inner heat insulation pad 231 to reduce the heat transfer between the second sheet metal 21 and the connector 23. The second sheet metal 21 and the third sheet metal 22 are also thermally isolated by the outer heat insulation board 24 to reduce the heat transfer between the second sheet metal 21 and the third sheet metal 22. At this time, the heat accumulated at the second sheet metal 21 is difficult to be transferred to the connector 23 and the third sheet metal 22 respectively. At the same time, the third sheet metal 22 and the connector 23 are thermally isolated by the outer heat insulation pad 232. The small amount of heat accumulated at the connector 23 is difficult to be transferred to the third sheet metal 22. After heat conduction, the heat accumulated at the third sheet metal 22 is finally reduced, which is conducive to improving the thermal insulation effect at the connector 23.

[0039] Embodiment 2:

[0040] The difference between this embodiment and the above embodiment is that Figure 2 The connecting member 23 includes a bolt 233, the threaded end of the bolt 233 sequentially penetrates the second sheet metal 21, the outer heat insulation board 24 and the third sheet metal 22, the bolt 233 is threadedly connected with a nut 234, and the bolt 233 and the nut 234 cooperate to connect the second sheet metal 21, the outer heat insulation board 24 and the third sheet metal 22. Among them, the inner heat insulation pad 231 is located between the nut of the bolt 233 and the second sheet metal 21, and the outer heat insulation pad 232 is located between the nut 234 and the third sheet metal 22 to play a heat insulation role.

[0041] In a preferred embodiment, the third sheet metal 22 is specifically arranged vertically, and the second sheet metal 21 includes a bending section 211, which is arranged around one side of the outer heat insulation board 24, and the bending section 211 and the corresponding end of the third sheet metal 22 are arranged at intervals to reduce the contact area between the second sheet metal 21 and the third sheet metal 22, thereby reducing the heat transfer between the second sheet metal 21 and the third sheet metal 22. The spacing between the bending section 211 and the third sheet metal 22 is 4 to 10 mm. In some specific embodiments shown, the spacing between the bending section 211 and the third sheet metal 22 is 4 mm, and a suitable gap is maintained between the second sheet metal 21 and the third sheet metal 22, so that the connection insulation structure is compact and forms a certain thermal bridge partition.

[0042] Embodiment 3:

[0043] The difference between this embodiment and the above embodiment is that Figure 1 and Figure 2 The second sheet metal 21 is spaced apart from the first sheet metal 1. A gap exists between the second sheet metal 21 and the first sheet metal 1, which reduces the thermal bridge. The heat at the first sheet metal 1 is difficult to be directly transferred to the second sheet metal 21, and the heat radiation absorbed by the second sheet metal 21 is reduced.

[0044] In a preferred embodiment, the bending section 211 and the corresponding end of the third sheet metal 22 are spaced apart to reduce the contact area between the second sheet metal 21 and the third sheet metal 22, thereby reducing the heat transfer between the second sheet metal 21 and the third sheet metal 22. The spacing between the bending section 211 and the third sheet metal 22 is 4 to 10 mm. In some specific embodiments shown, the spacing between the bending section 211 and the third sheet metal 22 is 10 mm, and a suitable spacing is formed between the bending section 211 and the third sheet metal 22 to reduce the heat transfer between the second sheet metal 21 and the third sheet metal 22, which is conducive to further reducing the heat accumulated at the third sheet metal 22.

[0045] The first sheet metal 1 and the second sheet metal 21 are spaced apart, and the second sheet metal 21 and the third sheet metal 22 are spaced apart at the bending section 211, respectively, so as to form heat transfer partitions on the heat transfer path, thereby forming a good heat insulation effect between the hot structure and the cold structure.

[0049] The door frame 3 is in contact with the external environment. When the door frame 3 is overheated, it is difficult for the oven to ensure the required temperature difference between the inside and the outside. In a preferred embodiment, the first sheet metal 1 and the third sheet metal 22 are spaced apart from the door frame 3, respectively, which can reduce the heat transfer between the first sheet metal 1 and the door frame 3, and between the third sheet metal 22 and the door frame 3, thereby reducing the possibility of overheating in the door frame 3. Furthermore, an inner heat insulation board 32 is provided between the door frame 3 and the first sheet metal 1, wherein the thermal conductivity of the inner heat insulation board 32 is 0.05-0.5W / (m﹒K), the specific heat capacity is 400-1000J / Kg, and the density is 0.5-2.0g / cm 3 The inner heat insulation board 32 can block the heat transfer between the door frame 3 and the first sheet metal 1. It can be understood that this is not a specific limitation on the inner heat insulation board 32, and technicians in the relevant field can replace or improve it on this basis.

[0050] As shown in some specific embodiments, the spacing between the bending section 211 of the second sheet metal 21 and the third sheet metal 22 is 6 mm, and a suitable spacing is formed between the bending section 211 and the third sheet metal 22 to reduce heat transfer between the second sheet metal 21 and the third sheet metal 22, which is beneficial to further reduce the heat accumulated in the third sheet metal 22.
