Description

Technical Field

[0001] The utility model relates to the technical field of heat cleaning furnaces, and specifically relates to a special heat insulation and heat preservation structure for heat cleaning furnaces. Background Technique

[0002] A heat cleaning furnace is a device specifically used for cleaning chemicals attached to metal parts. Through an efficient washing process, it not only reduces cost expenditures but also reduces the impact on the environment. The working principle of the heat cleaning furnace is based on the characteristics of high molecular polymers at a specific temperature. Due to the particularity of the operation of the heat cleaning furnace, the heat preservation structure of the heat cleaning furnace needs to be adaptively configured to ensure the operation of the heat cleaning furnace.

[0003] When the existing heat cleaning furnace is in use, gaps are likely to occur between the door body and the furnace body of the heat cleaning furnace, resulting in heat convection and conduction at the door gap, and heat loss from the edge of the door body. Content of the Utility Model

[0004] The purpose of the utility model is to provide a special heat insulation and heat preservation structure for heat cleaning furnaces to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A special heat insulation and heat preservation structure for heat cleaning furnaces, including a furnace body and a viewing window. An auxiliary component for preventing heat loss is arranged outside the furnace body, and the auxiliary component includes a door body, an inner plate, and an alumina fiber felt layer. An inner plate is arranged inside the door body, and an alumina fiber felt layer is installed between the door body and the inner plate. The viewing window is arranged in the middle of the inner plate.

[0006] Furthermore, fixed plates are installed on both the upper and lower sides outside the door body, and a rotating shaft is rotatably installed at the bottom of one side of the fixed plate.

[0007] Furthermore, the end of the rotating shaft is provided with a furnace body, and a sealing layer is installed on the front side of the furnace body.

[0008] Furthermore, a heat insulation component for heat preservation is arranged inside the furnace body, and the heat insulation component includes a first heat preservation layer and a second heat preservation layer. The second heat preservation layer is installed on both sides of the bottom of the first heat preservation layer.

[0009] Furthermore, there are two groups of the first heat preservation layer and two groups of the second heat preservation layer.

[0010] Furthermore, the first heat preservation layer and the second heat preservation layer are snap-connected, and the thickness of the first heat preservation layer is greater than the thickness of the second heat preservation layer.

[0011] Furthermore, the length and width of the alumina fiber felt layer are greater than the length and width of the sealing layer, and the alumina fiber felt layer is in a "mouth" - shaped structure.

[0012] Furthermore, an inner refractory layer is provided on the outer side of the first and second insulation layers, and an aluminum foil reflective layer is installed on the outer surface of the furnace body.

[0013] This utility model provides a heat insulation structure specifically for thermal cleaning furnaces, which has the following beneficial effects:

[0014] 1. This utility model features a double-layer sealing design through the contact between the furnace body and the door. The sealing layer is made of high-temperature resistant silicone strips and ceramic fiber filling. Furthermore, the door can rotate to cover the front of the furnace body by the interaction of the pivot and the fixing plate. The alumina fiber felt layer embedded in the edge of the door frame can surround and lock the outside of the sealing layer, which can block heat convection and conduction at the door gap and prevent heat loss from the edge of the door.

[0015] 2. This utility model, through the design of the heat insulation component, disconnects the direct heat conduction path of the metal, reduces thermal bridges, and thus makes the heat insulation component more effective in heat insulation and heat preservation, making the heat cleaning furnace safer to use and longer in service life. At the same time, the outer metal shell protects the first and second heat insulation layers. In addition, the difference in thickness between the first and second heat insulation layers allows for zoned reinforcement of key areas where heat loss occurs at the top and bottom of the furnace body.

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] like Figure 1 and Figure 2As shown, a heat insulation structure for a thermal cleaning furnace includes a furnace body 1, a sealing layer 2, a rotating shaft 3, a fixing plate 4, auxiliary components 5, a door 501, an inner plate 502, an alumina fiber felt layer 503, a viewing window 6, an inner refractory layer 7, a heat insulation component 8, a first insulation layer 801, a second insulation layer 802, and an aluminum foil reflective layer 9. The furnace body 1 is externally equipped with auxiliary components 5 to prevent heat loss. These auxiliary components 5 include a door 501, an inner plate 502, and an alumina fiber felt layer 503. The inner plate 502 is located inside the door 501, and an alumina fiber felt layer 503 is installed between the door 501 and the inner plate 502. The length and width of the alumina fiber felt layer 503 are greater than the length and width of the sealing layer 2, and the alumina fiber felt layer 503 has a "U"-shaped structure. The outer surface of the door 501... Fixed plates 4 are installed on both sides of the bottom, and a rotating shaft 3 is rotatably installed on one bottom side of the fixed plate 4. The furnace body 1 is set at the end of the rotating shaft 3, and a sealing layer 2 is installed on the front side of the furnace body 1. A viewing window 6 is set in the middle of the inner plate 502. The viewing window 6 is made of vacuum glass and is used to observe the inside of the furnace body 1. The contact between the furnace body 1 and the door 501 is designed with a double-layer sealing, that is, it is sealed by a sealing layer 2 made of high-temperature resistant silicone strip and ceramic fiber filling. By utilizing the interaction between the rotating shaft 3 and the fixed plate 4, the door 501 can rotate to cover the front side of the furnace body 1. Thus, the alumina fiber felt layer 503 embedded in the edge of the door frame of the door 501 can surround and lock the outside of the sealing layer 2, which can block the heat convection and conduction at the door gap and prevent heat from being lost from the edge of the door 501.

[0022] like Figure 3 As shown, the furnace body 1 is internally equipped with a heat insulation component 8 for heat preservation. The heat insulation component 8 includes a first heat insulation layer 801 and a second heat insulation layer 802. The second heat insulation layer 802 is installed on both sides of the bottom of the first heat insulation layer 801. There are two sets of the first heat insulation layer 801 and two sets of the second heat insulation layer 802. The first heat insulation layer 801 and the second heat insulation layer 802 are interlocked, and the thickness of the first heat insulation layer 801 is greater than the thickness of the second heat insulation layer 802. An inner refractory layer 7 is provided on the outer side of the first heat insulation layer 801 and the second heat insulation layer 802. The furnace body 1 is externally... The surface is equipped with an aluminum foil reflective layer 9. The furnace body 1 adopts a metal shell design. Both the first insulation layer 801 and the second insulation layer 802 are made of lightweight refractory material filled with aluminum silicate fiber. The direct heat conduction path of the metal is interrupted by the heat insulation component 8 to reduce thermal bridges. At the same time, the outer metal shell protects the first insulation layer 801 and the second insulation layer 802. In addition, by using the difference in thickness between the first insulation layer 801 and the second insulation layer 802, the key areas of heat loss at the top and bottom of the furnace body 1 can be reinforced in a zoned manner. The thickened design can significantly improve the overall heat preservation efficiency.

[0023] In summary, the thermal insulation structure specifically designed for this heat-cleaning furnace is first based on... Figures 1-3In the structure shown, during use, the inner refractory layer 7 directly contacts the inner wall of the high-temperature furnace, using high-alumina refractory bricks or lightweight refractory castables. The furnace body 1 and the door 501 are connected by a double-layer sealing design. This is achieved through a sealing layer 2 made of high-temperature resistant silicone strips and ceramic fiber filling. Furthermore, the door 501 rotates and covers the front of the furnace body 1 via the interaction of the rotating shaft 3 and the fixing plate 4. This allows the alumina fiber felt layer 503 embedded in the door frame edge of the door 501 to surround the furnace body. The outer layer of the sealing layer 2 is locked to block heat convection and conduction at the door gap. Finally, the furnace body 1 adopts a metal shell design. Both the insulation layer 1 (801) and the insulation layer 2 (802) are filled with lightweight refractory material filled with aluminum silicate fiber. The heat insulation component 8 disconnects the direct heat conduction path of the metal and reduces thermal bridges. At the same time, the outer metal shell protects the insulation layer 1 (801) and the insulation layer 2 (802). In addition, the difference in thickness between the insulation layer 1 (801) and the insulation layer 2 (802) can be used to strengthen the key areas of heat loss at the top and bottom of the furnace body 1.
