Description

Technical Field

[0001] This application relates to the technical field of furnace doors, and in particular to the structure of intelligent temperature-controlled gradient heat treatment furnace doors. Background Technology

[0002] Heat treatment furnaces are key equipment in industrial production used for heat treatment processes such as heating, holding, and cooling of workpieces. The insulation performance of the furnace door structure directly affects the heat treatment effect and energy consumption. Traditional heat treatment furnace doors typically use single-layer or simple double-layer insulation structures, which have limited insulation effects. This allows heat to easily dissipate through the furnace door, increasing energy consumption and making it difficult to maintain the stability of the furnace temperature, thus affecting the heat treatment quality of the workpieces.

[0003] Meanwhile, the linings of traditional furnace doors are mostly planar structures, which cannot effectively reflect heat from the furnace, further exacerbating heat loss. Furthermore, some furnace doors have poor sealing performance, easily leading to heat leakage at the junction of the door and the furnace body. This not only reduces thermal efficiency but may also pose safety hazards to operators. With increasing industrial energy-saving requirements and the development of intelligent temperature control technology, traditional furnace door structures can no longer meet the demands of high-precision, low-energy-consumption heat treatment processes. Therefore, there is an urgent need for a furnace door structure with excellent insulation, sealing performance, and heat reflection capabilities. Therefore, to solve the above problems, this application provides an intelligent temperature-controlled gradient heat treatment furnace door structure. Utility Model Content

[0004] To address the aforementioned issues, this application provides an intelligent temperature-controlled gradient heat treatment furnace door structure.

[0005] The intelligent temperature-controlled gradient heat treatment furnace door structure provided in this application is characterized by comprising a door panel, a hinge, a sealing strip, and an inner lining layer; the hinge is installed on the side of the door panel for connecting the furnace door to the heat treatment furnace body; the sealing strip is disposed on the edge of the door panel for sealing when the furnace door is closed; the inner lining layer is disposed on the side of the door panel facing the furnace interior, and the middle part of the inner lining layer forms a concave portion for reflecting internal heat back into the furnace.

[0006] By designing the door body as a series of components from the outside in, consisting of a door panel, an outer insulation layer, a support layer, an inner insulation layer, and an inner lining layer, with the middle part of the inner lining layer recessed to reflect internal heat back into the furnace, a better insulation effect is achieved.

[0007] Preferably, an outer insulation layer, a support layer, and an inner insulation layer are sequentially arranged between the inner lining layer and the door panel from the outside to the inside; the outer insulation layer is close to the door panel, the inner insulation layer is close to the inner lining layer, and the support layer is located between the outer insulation layer and the inner insulation layer to enhance the strength of the furnace door structure.

[0008] Preferably, the outer insulation layer and the inner insulation layer are made of high-temperature resistant insulation material, and the support layer adopts a metal frame structure.

[0009] Preferably, the recessed portion is a square cavity structure, and the inner surface of the recessed portion is treated with a high reflectivity material.

[0010] Preferably, the sealing strip is a high-temperature resistant elastic sealing strip, and it is arranged circumferentially along the edge of the door panel.

[0011] In summary, this application includes the following beneficial technical effects:

[0012] The core benefit of this application lies in the comprehensive improvement of thermal insulation performance and operational efficiency achieved through the synergistic effect of multi-layer composite structure and functional design. Specifically, the furnace door adopts a gradient structure consisting of a door panel, an outer insulation layer, a support layer, an inner insulation layer, and an inner lining layer, distributed sequentially from the outside to the inside. The outer and inner insulation layers are made of high-temperature resistant insulation materials with different properties, forming a double thermal insulation barrier, which can significantly reduce heat loss through solid conduction. The metal frame structure of the support layer not only avoids deformation or collapse of the insulation layer due to long-term use at high temperatures, but also enhances the overall rigidity of the furnace door and extends the service life of the equipment.

[0016] The following is in conjunction with the appendix Figure 1 - Figure 2 This application will be described in further detail.

[0017] Example 1:

[0018] Intelligent temperature control gradient heat treatment furnace door structure, referencing Figure 1 - Figure 2 It includes door panel 1, hinge 2, sealing strip 3, inner lining layer 4, inner insulation layer 5, support layer 6, and outer insulation layer 7.

[0019] The hinge 2 is installed on the side of the door panel 1. The hinge 2 allows the entire furnace door to be movably connected to the heat treatment furnace body, enabling the furnace door to rotate around the hinge 2 to open and close. The hinge 2 is made of high-temperature resistant alloy material, ensuring good structural stability and service life even in high-temperature environments.

[0020] The sealing strip 3 is located at the edge of the door panel 1 and is arranged continuously in a circumferential manner along the edge of the door panel 1. The sealing strip 3 is made of high-temperature resistant silicone rubber material, which has good elasticity and high-temperature resistance. When the furnace door is closed, the sealing strip 3 can fit tightly against the furnace door frame, effectively preventing heat from leaking out of the furnace and preventing cold air from entering the furnace, thus ensuring the stability of the furnace temperature.

[0021] The door panel 1, facing inwards from the furnace, is sequentially equipped with an outer insulation layer 7, a support layer 6, an inner insulation layer 5, and an inner lining layer 4, forming a multi-layered composite structure from the outside in. The outer insulation layer 7 is tightly fitted to the door panel 1 and is made of aluminum silicate fiber cotton, providing excellent thermal insulation performance. The support layer 6 is located between the outer insulation layer 7 and the inner insulation layer 5, employing a stainless steel frame structure with a grid-like distribution. This frame not only provides reliable support for the outer insulation layer 7 and the inner insulation layer 5, preventing deformation or collapse of the insulation layers due to long-term use, but also enhances the structural strength of the entire furnace door. The inner insulation layer 5 is positioned close to the inner lining layer 4 and is made of lightweight, high-temperature resistant ceramic fiberboard. Together with the outer insulation layer 7, it forms a double insulation structure, further improving the insulation effect of the furnace door. The inner lining layer 4 is made of high-temperature resistant metal sheet, and its surface facing inwards from the furnace is polished to form a highly reflective surface, effectively reflecting heat from inside the furnace.

[0022] The inner lining layer 4 has a concave portion 41 in the middle, which is a square cavity structure with a depth of 5-10 cm. The concave portion 41 makes the inner lining layer 4 form a structure similar to a concave mirror. When heat radiates from the furnace to the inner lining layer 4, the concave portion 41 can concentrate and reflect the heat back into the furnace, reducing heat loss through the furnace door, thereby improving the thermal efficiency and heat preservation performance of the heat treatment furnace.

[0023] The intelligent temperature-controlled gradient heat treatment furnace door structure in this embodiment significantly improves the insulation effect of the furnace door through multi-layer insulation design and an inner lining structure with concave parts, reduces heat loss, helps maintain the stability of the furnace temperature, reduces energy consumption, and extends the service life of the furnace door.

However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, the protection scope of which is determined by the appended claims.
