Description

Technical Field

[0001] Embodiments of the present disclosure relate to the technical field of heating furnaces, and more specifically, to a heat-insulating furnace body for a heating furnace. Background Art

[0002] In the application field of heating furnaces, the heat insulation performance of the furnace body plays a crucial role in the effective utilization of energy, the stable operation of equipment, and the control of production costs. However, many problems have emerged in the actual use of traditional heat-insulating furnace bodies for heating furnaces, making it difficult to meet the requirements of modern industry for high efficiency, energy conservation, and easy maintenance.

[0003] The structural design of the heat-insulating furnace body for a heating furnace is often relatively simple, and the heat-insulating material usually adopts a single structure of an integral type or a spliced type. Although the integral heat-insulating structure can provide relatively good heat insulation effect to a certain extent, due to its non-detachable characteristics, once local damage occurs, the entire heat-insulating layer needs to be replaced, which not only incurs high maintenance costs but also takes a long time, seriously affecting the normal operation of the heating furnace. Although the spliced heat-insulating structure is relatively convenient for installation, due to the insufficient tight connection between the spliced components, gaps are likely to appear, resulting in heat loss through radiation and conduction, reducing the heat insulation performance.

[0004] Most of the heat-insulating materials of traditional heat-insulating furnace bodies do not have the characteristics of modular production and installation. The size and structure of the heat-insulating materials lack unified standards, which requires a large amount of customization and adjustment work during production and installation, increasing the difficulty and cost of production and installation. Moreover, due to the inflexible installation method of the heat-insulating materials, it is easy to have an insecure installation during the installation process, affecting the heat insulation effect.

[0005] In terms of maintenance, traditional heat-insulating furnace bodies have obvious deficiencies. When a certain part of the heat-insulating furnace body is damaged, due to the limitations of its structural design, maintenance personnel often need to remove a large number of heat-insulating components to replace the damaged part, which not only increases the difficulty and time of maintenance but also may cause damage to other undamaged heat-insulating components, further increasing the maintenance cost. Moreover, during the operation of traditional heat-insulating furnace bodies, due to the relative displacement between the heat-insulating materials, the structural stability of the heat-insulating layer is likely to decrease, affecting the heat insulation effect. Summary of the Invention

[0011] For example, at least one embodiment of the present disclosure provides a heating furnace insulation furnace body, wherein the filling member includes: Swing plates, there are two swing plates, the two swing plates are hingedly arranged, a clamping groove is formed between the two swing plates, and the swing plate is arranged to abut against the groove wall of the removal groove; A wedge block is arranged in the clamping groove, the wedge block has an extended end, the extended end is located outside the clamping groove, the extended end has a groove portion, the positioning ring is arranged in the groove portion and abuts against the side wall of the extended end.

[0012] For example, at least one embodiment of the present disclosure provides a heating furnace insulation furnace body, wherein the protruding end has a yield guide surface, and the wedge block is configured so that when the positioning ring slides along the yield guide surface, the wedge block gradually gets stuck in the clamping groove.

[0013] For example, at least one embodiment of the present disclosure provides a heating furnace insulation furnace body, wherein the swing plate has an arc-shaped plate portion, the arc-shaped plate portion abuts against the inner surface of the arc-shaped insulation member, the arc-shaped plate portion has a mounting portion, and the heating furnace insulation furnace body further includes: A heating wire, the heating wire is arranged on the installation part.

[0014] For example, a heat-insulating furnace body of a heating furnace provided by at least one embodiment of the present disclosure, a heat-insulating gap is formed between the removal groove and the filling piece, and the heat-insulating furnace body of the heating furnace further includes: A filling layer, the filling layer is located in the heat-insulating gap and is used to prevent the heat-insulating gap from dissipating heat.

[0015] For example, a heat-insulating furnace body of a heating furnace provided by at least one embodiment of the present disclosure, the heat-insulating furnace body of the heating furnace further includes: A housing, the housing is arranged outside the heat-insulating layer, and there is a buffer space between the housing and the heat-insulating layer; A heat-insulating layer, the heat-insulating layer is arranged in the buffer space.

[0016] For example, a heat-insulating furnace body of a heating furnace provided by at least one embodiment of the present disclosure, the housing includes: A shell, the shell has a heat-insulating cavity; A first heat-dissipating layer, the first heat-dissipating layer is arranged on the cavity wall of the heat-insulating cavity close to the heat-insulating layer side; A second heat-dissipating layer, the second heat-dissipating layer is arranged on the cavity wall of the heat-insulating cavity far from the heat-insulating layer side, and there is a gap between the first heat-dissipating layer and the second heat-dissipating layer.

The removal groove formed between two adjacent arc-shaped heat-insulating parts facilitates the maintenance and replacement of the heat-insulating parts. When a certain arc-shaped heat-insulating part is damaged and needs to be replaced, there is no need to remove the entire heat-insulating layer. Only the damaged arc-shaped heat-insulating part needs to be taken out through the removal groove, and a new arc-shaped heat-insulating part can be replaced.

The arc-shaped heat preservation parts between different heat preservation rings are staggered, further improving the structural stability and integrity. In practical applications, even if some of the arc-shaped heat preservation parts are slightly damaged, due to the support of the staggered arrangement and the multi-layer structure, it will not have a serious impact on the function of the entire heat preservation layer, ensuring the normal operation of the heating furnace.

Detailed Embodiment

[0023] The present disclosure will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present disclosure, rather than limiting the present disclosure.

[0024] To make the drawings concise, only the parts related to the disclosure are schematically shown in each drawing, and they do not represent the actual structure of the product.

[0025] In this article, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components.

[0028] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions, and cannot be understood as indicating or implying relative importance.

[0029] Such as Figures 1 to 7As shown, it shows a heat-insulating furnace body in an embodiment of the present disclosure, including arc-shaped heat-insulating members 1. There are several arc-shaped heat-insulating members 1, which are arranged in a circumferential arrangement. The arc-shaped heat-insulating member 1 has a lapping part 101 and a supporting part 102. The lapping part 101 is lapped on the supporting part 102 of another adjacent arc-shaped heat-insulating member 1. A removal groove 103 is formed between two adjacent arc-shaped heat-insulating members 1. Several arc-shaped heat-insulating members 1 enclose a heat-insulating ring 104. There are several heat-insulating rings 104, which are arranged along the axis of the heat-insulating ring 104. The arc-shaped heat-insulating members 1 of two adjacent heat-insulating rings 104 are staggered. Several heat-insulating rings 104 form a heat-insulating layer 2. A filling member 3 is arranged in the removal groove 103.

[0030] For example, as Figures 1 to 7 shown, the designs of the arc-shaped heat-insulating member 1 and the heat-insulating ring 104 have modular characteristics. The size and structure of each arc-shaped heat-insulating member 1 are relatively unified, which is convenient for mass production and installation. During the installation process, the arc-shaped heat-insulating members 1 can be first assembled into the heat-insulating ring 104, and then the heat-insulating rings 104 are installed layer by layer, greatly improving the installation efficiency. Several arc-shaped heat-insulating members 1 are arranged in a circumferential arrangement to enclose the heat-insulating ring 104, and the arc-shaped heat-insulating members 1 of adjacent heat-insulating rings 104 are staggered. The staggered heat-insulating rings 104 enable the positions of other arc-shaped heat-insulating members 1 to be unaffected when one arc-shaped heat-insulating member 1 is removed, which can reduce the time for an operator to replace a damaged arc-shaped heat-insulating member 1 when the arc-shaped heat-insulating member 1 is damaged, improve the maintenance efficiency, and at the same time reduce the maintenance cost. The filling member 3 is arranged in the removal groove 103 to block the heat from being transferred out by radiation and conduction. At the same time, the filling member 3 can provide a squeezing force to the arc-shaped heat-insulating members 1 on both sides, ensuring that the arc-shaped heat-insulating members 1 are not prone to relative displacement and ensuring the service life of the heat-insulating ring 104.

[0031] The lapping part 101 of the arc-shaped heat-insulating member 1 is lapped on the supporting part 102 of the adjacent arc-shaped heat-insulating member 1. This lapping structure forms a stable system of mutual support. Each arc-shaped heat-insulating member 1 is closely connected to adjacent components through the lapping part 101 and the supporting part 102, dispersing the pressure and external force received by the furnace body. The removal groove 103 formed between two adjacent arc-shaped heat-insulating members 1 provides convenience for the maintenance and replacement of the heat-insulating members. When a certain arc-shaped heat-insulating member 1 is damaged and needs to be replaced, there is no need to remove the entire heat-insulating layer 2. Only the damaged arc-shaped heat-insulating member 1 needs to be taken out through the removal groove 103 and a new arc-shaped heat-insulating member 1 is replaced. This design greatly reduces the maintenance difficulty and cost and shortens the maintenance time.

[0032] A plurality of heat preservation rings 104 are arranged along the axis to form a heat preservation layer 2. The multiple heat preservation rings 104 are superposed on each other, enhancing the overall strength of the heat preservation layer. The arc-shaped heat preservation parts 1 between different heat preservation rings 104 are arranged alternately, further improving the stability and integrity of the structure. In practical applications, even if some of the arc-shaped heat preservation parts 1 are slightly damaged, due to the supporting effect of the staggered arrangement and the multi-layer structure, it will not have a serious impact on the function of the entire heat preservation layer 2, ensuring the normal operation of the heating furnace.

[0033] In some examples, the arc-shaped heat preservation part 1 also has a relief inclined surface 105. A removal groove 103 is formed between the overlapping part 101 or the supporting part 102 of one arc-shaped heat preservation part 1 and the relief inclined surface 105 of an adjacent arc-shaped heat preservation part 1.

[0034] For example, as Figures 3 to 4 shown, the two relief inclined surfaces 105 are respectively located below the overlapping part 101 and above the supporting part 102. When installing the arc-shaped heat preservation part 1, this design can guide the rapid and accurate positioning between adjacent arc-shaped heat preservation parts 1. The overlapping part 101 can be smoothly overlapped on one side of the relief inclined surface 105 of the supporting part 102, reducing the number of fine-tuning of the position during the installation process. A removal groove 103 is formed between the overlapping part 101 or the supporting part 102 of one arc-shaped heat preservation part 1 and the relief inclined surface 105 of an adjacent arc-shaped heat preservation part 1. This structure provides better space for the installation of the filling part 3. The filling part 3 can be more closely filled in the removal groove 103, further enhancing the heat preservation performance. Due to the existence of the relief inclined surface 105, the filling part 3 can better adapt to the shape of the removal groove, reducing the situation of insufficient filling.

[0035] When it is necessary to repair or replace the arc-shaped heat preservation part 1, the existence of the relief inclined surface 105 makes the removal process more convenient. The arc-shaped structure of the arc-shaped heat preservation part 1 makes it necessary to remove a single arc-shaped heat preservation part 1 from the outside of the heat preservation layer 2 after forming the heat preservation ring 104. In a heating furnace, the work efficiency of removing the arc-shaped heat preservation part 1 from the outside is close to that of replacing the entire heat preservation layer 2. However, the design of the relief inclined surface 105 enables the arc-shaped heat preservation part 1 to be removed from the inside. When removing the arc-shaped heat preservation part 1, the adjacent relief inclined surfaces 105 play a guiding role, enabling the arc-shaped heat preservation part 1 to be removed inside the heat preservation ring 104, improving the maintenance efficiency.

[0036] In some examples, the included angle between the relief inclined surface 105 and an adjacent overlapping part 101 or supporting part 102 is half of the included angle of the two end faces of the arc-shaped heat preservation part 1.

[0037] For example, as Figure 3As shown, when the angle between the giving way slope 105 and another adjacent overlapping portion 101 or supporting portion 102 is half of the angle between the two end surfaces of the arc-shaped thermal insulation component 1, after the arc-shaped thermal insulation components 1 are overlapped with each other, this special angle setting can form a parallelogram-shaped channel between the two adjacent giving way slopes 105 when the arc-shaped thermal insulation component 1 is removed, thereby facilitating the removal and installation of the arc-shaped thermal insulation component 1.

[0038] In some examples, the insulation ring 104 has a heating cavity 106, and the insulation furnace body of the heating furnace also includes a positioning ring 4, which is arranged in the heating cavity 106. There are several positioning rings 4, which are arranged along the axis of the insulation ring 104 and abut against the filling piece 3 to fix the filling piece 3.

[0039] For example, Figures 3 to 6 As shown, the positioning ring 4 is arranged in the heating chamber 106 and abuts against the filling piece 3, which can ensure that the filling piece 3 is accurately filled in the gap position such as the removal groove 103. The presence of the positioning ring 4 prevents the filling piece 3 from shifting or insufficient filling during use, ensuring a tight fit between the filling piece 3 and the insulation ring 4.

[0040] During the operation of the heating furnace, the insulation layer 2 will be affected by certain pressure and temperature changes. The positioning ring 4 can support the filler 3 to prevent the filler 3 from being deformed or displaced due to extrusion. Several positioning rings 4 are arranged along the axis of the insulation ring 104 to form a support structure in the heating chamber 106. These positioning rings 4 cooperate with the insulation ring 104 and the filler 3 to enhance the overall strength and rigidity of the insulation ring 104.

[0041] In some examples, the filling piece 3 includes a swing plate 301, there are two swing plates 301, the two swing plates 301 are hingedly arranged, a clamping groove 302 is formed between the two swing plates 301, the swing plate 301 is abutted against the groove wall of the removal groove 103, a wedge block 303 is arranged in the clamping groove 302, the wedge block 303 has an extended end 304, the extended end 304 is located outside the clamping groove 302, the extended end 304 has a groove portion 305, and the positioning ring 4 is arranged in the groove portion 305 and abuts against the side wall of the extended end 304.

[0042] For example, Figure 4As shown, the two hinged swing plates 301 can be adaptively adjusted according to the shape of the removal groove 103 and are in close contact with the groove walls of the removal groove 103. This close fit effectively reduces the flow space of air in the removal groove 103 and reduces heat transfer caused by air convection. The wedge block 303 is arranged in the clamping groove 302, and through its wedge-shaped structure, the two swing plates 301 can be spread apart, making the swing plates 301 fit more closely with the groove walls of the removal groove 103 and having a better filling effect. Moreover, this design can be finely adjusted according to the actual size of the removal groove 103 to ensure that the filling member 3 can completely fill the removal groove 103 and avoid voids.

[0043] The structure in which the two swing plates 301 are hinged and clamped by the wedge block 303 provides good stability for the filling member 3. During the operation of the heat preservation furnace body, it will be affected by factors such as temperature changes and mechanical vibrations, and this clamping structure can effectively resist these external forces and prevent the filling member 3 from loosening or shifting. When the heat preservation furnace body expands and contracts due to temperature changes, the structures of the wedge block 303 and the swing plate 301 can disperse stress and avoid stress concentration at a certain part. When installing the filling member 3, the two hinged swing plates 301 can first be in a closed state, which is convenient for placing them into the removal groove 103. Then, by inserting the wedge block 303, the swing plates are spread apart to make them in contact with the groove walls, achieving rapid positioning and installation.

[0044] When the heating furnace experiences different temperature conditions, this structure of the filling member can better adapt to the influence brought by temperature changes. When the temperature rises, the swing plate 301 and the wedge block 303 can make minor adjustments to adapt to the expansion of the heat preservation material; when the temperature drops, it can also maintain a good filling state and prevent voids. For example, in some heating furnaces that need to frequently raise and lower the temperature, the filling member of this design can stably play the role of heat preservation and ensure the stable performance of the heat preservation furnace body.

[0045] Due to the adjustability of the swing plate 301 and the wedge block 303, the filling member 3 can adapt to removal grooves 103 of different sizes. Whether there are differences in the width, depth or shape of the removal groove 103, by adjusting the position of the wedge block 303 or replacing wedge blocks 303 of different specifications, the swing plate 301 can be in close contact with the groove walls to achieve a good filling effect. This adaptability enables the filling member of this design to be applied to various heat preservation furnace bodies of different specifications, improving its versatility and applicability.

[0046] In some examples, the protruding end 304 has a relief guiding surface 306, and the wedge block 303 is configured such that when the positioning ring 4 slides along the relief guiding surface 306, the wedge block 303 gradually engages into the clamping groove 302.

[0047] For example, as Figures 4 to 5As shown, the setting of the yielding guide surface 306 provides a clear guide path for the installation of the positioning ring 4. When the positioning ring 4 slides along the yielding guide surface 306, it can automatically center and guide the wedge block 303 to gradually fit into the clamping groove 302 under its own gravity or external force. This automatic centering function reduces the need for precise adjustment of the position of the positioning ring 4 during the installation process, and the installer does not need to spend a lot of time and energy to align the components.

[0048] The positioning ring 4 slides along the guide surface 306 to gradually clamp the wedge block 303 into the clamping groove 302, so that the two swing plates 301 can be evenly spread apart. This uniform clamping method makes the pressure distribution between the swing plate 301 and the groove wall of the removal groove 103 more uniform, avoiding the stress concentration problem caused by excessive local pressure.

[0049] The wedge block 303 is gradually inserted by giving way to the guide surface 306, which can ensure a tight fit between the wedge block 303 and the clamping groove 103. This tight fit increases the stability of the internal structure of the filling piece 3, and prevents the wedge block 303 from loosening or falling off during the operation of the insulation furnace body. In actual operation, this design can effectively resist the displacement of components caused by factors such as thermal expansion and contraction, vibration, etc., and ensure the reliability of the connection between the filling piece 3 and the positioning ring 4.

[0050] In some examples, the swing plate 301 has an arc-shaped plate portion 307 , which abuts against the inner surface of the arc-shaped insulation component 1 , and the arc-shaped plate portion 307 has a mounting portion 308 . The heating furnace insulation furnace body also includes a heating wire 5 , which is arranged on the mounting portion 308 .

[0051] For example, Figures 4 to 5 As shown, the arc plate portion 307 is in close contact with the inner surface of the arc-shaped insulation member 1. This fitting method can better fill the gaps between the insulation members, reduce the air flow space in the gaps, and thus reduce the heat transfer caused by air convection. The existence of the arc plate portion 307 optimizes the structure of the insulation layer, making it more continuous and complete. During the operation of the insulation furnace body, temperature changes will cause the insulation material to expand and contract. The arc plate portion 307 can better adapt to this change, maintain close contact with the inner surface of the arc-shaped insulation member 1, and prevent gaps from appearing due to material deformation.

[0052] The heating wire 5 is arranged on the mounting portion 308 of the arc plate portion 307, which can more effectively transfer heat to the interior of the heat preservation furnace body. Since the arc plate portion 307 is closely attached to the inner surface of the heat preservation member, the heat generated by the heating wire can be more evenly distributed around the heat preservation layer 2, avoiding local overheating or overcooling.

[0053] The abutment of the arc-shaped plate portion 307 against the inner surface of the arc-shaped heat-insulating member 1 increases the contact area between the filling member 3 and the heat-insulating member, thereby improving the connection stability. When the heat-insulating furnace body is subjected to external forces such as mechanical vibration or thermal expansion and contraction, this larger contact area can better disperse stress and avoid damage to the connection part caused by stress concentration.

[0054] In some examples, a heat-insulating gap 309 is formed between the removal groove 103 and the filling member 3. The heat-insulating furnace body of the heating furnace further includes a filling layer 6, and the filling layer 6 is located in the heat-insulating gap 309 and is used to prevent heat dissipation from the heat-insulating gap 309.

[0055] For example, as Figure 3 shown, the filling layer 6 is located in the heat-insulating gap 309, which can effectively block the path of heat dissipation through this gap. The heat-insulating gap 309 might originally become a channel for heat conduction, convection, and radiation, but the presence of the filling layer 6 reduces the occurrence of these heat transfer methods. If the heat-insulating gap 309 between the removal groove 103 and the filling member 3 is not treated, it is easy to form a heat bridge, resulting in concentrated heat dissipation. The setting of the filling layer 6 effectively eliminates this hidden danger and makes the heat-insulating performance of the heat-insulating layer 3 more uniform. After the filling layer 6 is filled in the heat-insulating gap 309, it can play a certain role in supporting and fixing the filling member 3. It can reduce the displacement or loosening of the filling member 3 caused by factors such as vibration, thermal expansion and contraction during the operation of the heat-insulating furnace body.

[0056] In some examples, the heat-insulating furnace body of the heating furnace further includes a housing 7, the housing 7 is arranged outside the heat-insulating layer 2, and there is a buffer space 701 between the housing 7 and the heat-insulating layer 2, and a heat-insulating layer 8 is arranged in the buffer space 701.

[0057] For example, as Figures 1 to 2 shown, the heat-insulating layer 8 is arranged in the buffer space 701 between the housing 7 and the heat-insulating layer 2, forming an additional heat-insulating barrier. The heat-insulating layer 2 can already effectively block most of the heat dissipation, and the presence of the heat-insulating layer 8 further reduces the heat transfer from the heat-insulating layer 2 to the external environment. The combination of the buffer space 701 and the heat-insulating layer 8 can also effectively reduce the impact of thermal radiation on the surrounding environment. When the heating furnace is operating, it will generate thermal radiation. If not controlled, it will not only cause energy waste, but also may affect the operators and surrounding equipment. The heat-insulating layer 8 can reflect and absorb part of the thermal radiation and reduce the temperature of the outer shell surface.

[0058] The buffer space 701 can buffer the external force impact on the heat-insulating layer 2 to a certain extent. When the heating furnace is subjected to mechanical vibration, collision or other external forces, the buffer space 701 can absorb part of the energy and reduce the direct action of the external force on the heat-insulating layer 2.

[0059] During the operation of the heating furnace, the insulation layer 2 will expand and contract due to temperature changes. The buffer space 701 provides a certain amount of space allowance for the thermal expansion and contraction of the insulation layer 2, enabling it to expand and contract freely and avoiding excessive stress caused by restricted thermal expansion and contraction. The presence of the heat insulation layer 8 also does not impede the thermal expansion and contraction of the insulation layer 2. In actual operation, this design can effectively prevent problems such as cracking and deformation of the insulation layer caused by thermal expansion and contraction, and maintain the integrity and heat insulation performance of the insulation layer 2.

[0060] Due to the function of the heat insulation layer 8, the surface temperature of the outer shell decreases, reducing the risk of scalding when the operator touches the outer shell. In an industrial production environment, the operator often needs to approach the heating furnace for operation and monitoring. The lower surface temperature of the outer shell 7 improves the safety of the working environment.

[0061] In some examples, the outer shell 7 includes a housing 701, the housing 701 has a heat insulation cavity 702, a first heat dissipation layer 703 is arranged on the cavity wall of the heat insulation cavity 702 close to the heat insulation layer 8, a second heat dissipation layer 704 is arranged on the cavity wall of the heat insulation cavity 702 far from the heat insulation layer 8, and there is a gap 705 between the first heat dissipation layer 703 and the second heat dissipation layer 704.

[0062] For example, as Figures 1 to 2 shown, the heat insulation cavity 702 of the housing 701 and the first heat dissipation layer 703 and the second heat dissipation layer 704 arranged on the cavity wall form multiple heat insulation barriers. The first heat dissipation layer 703 is close to the heat insulation layer 8 and can first absorb and block part of the heat transferred from the heat insulation layer 2; the second heat dissipation layer 704 is arranged on the side far from the heat insulation layer to further prevent the heat from dissipating to the external environment. The gap 705 between the two heat dissipation layers plays a role in air heat insulation, and the low thermal conductivity of air can effectively reduce heat conduction. For example, through thermal conduction test comparison, compared with the design with only a heat insulation layer, this multiple heat insulation structure can reduce the heat dissipation rate of the heating furnace by about 20%-30% again, greatly improving the heat insulation performance of the heat insulation furnace body and reducing energy consumption.

[0063] The presence of the heat insulation cavity 702 increases the structural thickness and rigidity of the outer shell 7. During the operation of the heating furnace, the outer shell 7 will be affected by various factors such as temperature changes and mechanical vibrations. The combined structure of the heat insulation cavity 702 and the two heat dissipation layers can better resist these external forces and reduce the deformation and damage of the outer shell 7.

[0064] The gap 705 between the first heat dissipation layer 703 and the second heat dissipation layer 704 provides a certain amount of space allowance for the thermal expansion and contraction of the housing 7 when the temperature changes. When the housing 7 expands due to temperature increase or contracts due to temperature decrease, the gap 705 can absorb part of the deformation amount, avoiding excessive stress caused by restricted thermal expansion and contraction. Due to the effect of the multiple heat insulation structures, the surface temperature of the housing 7 is effectively reduced. The lower surface temperature of the housing 7 reduces the risk of scalding when the operator touches the housing 7, improving the safety of the working environment.

[0065] In some examples, the heating wire 5 is spirally arranged on the heat insulation layer 2 and is located in the heating cavity 106. The heating furnace heat insulation furnace body further includes ceramic clamping parts 9. There are several ceramic clamping parts 9, which are arranged in a circumferential array in the heating cavity. The ceramic clamping parts 9 have fixing parts for fixing the heating wire 5.

[0066] For example, as Figure 7 shown, the heating wire 5 is spirally arranged on the heat insulation layer 2 and is located in the heating cavity 106. This arrangement can make the heat more evenly dissipated into the heating cavity. The spirally distributed heating wire 5 can cover a larger heating area, avoiding local overheating or uneven heating. Compared with the traditional heating wire arrangement method, after adopting the spiral arrangement, the temperature uniformity in the heating cavity is improved and the heating efficiency is improved.

[0067] The ceramic clamping parts 9 are arranged in a circumferential array in the heating cavity, and their fixing parts are used to fix the heating wire 5, effectively preventing the heating wire 5 from shifting or deforming during the heating process. The stable fixation can ensure that the heating wire 5 always stays in the appropriate position and continuously and stably generates heat, thereby improving the heating stability. Compared with the situation where there is no fixation by the ceramic clamping parts 9, the stability of the heating wire 5 is improved, reducing the heating faults caused by the displacement of the heating wire and ensuring the reliability of the heating effect.

[0068] The ceramic clamping parts 9 are made of ceramic materials and have good high-temperature resistance. During the heating process, the ceramic clamping parts 9 can withstand the test of the high-temperature environment and will not be damaged or deformed due to high temperature, ensuring the normal operation of the heating furnace heat insulation furnace body. Compared with the fixing components made of materials that are not resistant to high temperature, the failure rate of the furnace body using the ceramic clamping parts 9 is reduced in the high-temperature environment, the service life of the equipment is extended, and the equipment downtime and maintenance time caused by component damage are reduced.
