Description

Technical Field

[0001] This utility model relates to the field of thermal insulation and protection facilities technology, and in particular to a protective device for thermal insulation materials. Background Technology

[0002] Thermal insulation materials are heat-insulating materials composed of fiber materials. They maintain stable performance in environments below 2800℃, effectively reducing heat conduction to the furnace body through their low thermal conductivity, minimizing thermal shock, and maintaining the required temperature for the thermal field while reducing heat loss. However, because thermal insulation materials are composed of fiber materials, they are prone to fiber shedding and surface damage upon contact. In existing technologies, thermal insulation materials are susceptible to damage in the following situations: First, in industrial furnaces with large air volumes, the insulation material is easily impacted by strong airflow, causing fiber shedding. Especially during furnace cooling, the operation of high-power fans creates a large airflow within the furnace, flowing through the insulation material. Fibers easily shed from the front and rear ends of the insulation material, leading to breakage at the ends over time and reducing insulation performance. Second, in high-pressure equipment, the high pressure, high velocity, and strong impact of the airflow during high-pressure intake, coupled with the airflow outlet directly facing the insulation material, easily cause damage. Third, during material loading and unloading, tooling and other equipment can easily collide with and scrape the insulation material, leading to damage at the ends. Fourth, during sintering, powdered metals may melt and disperse into various corners of the furnace, especially at the insulation material's ends. Temperature differences can cause metal particles to condense and adhere to the insulation material's surface. At high temperatures, these particles can liquefy and penetrate the insulation material, causing burn damage. Fifth, there is a risk of processed materials falling onto the insulation material during loading and unloading. During airflow, these materials can be blown to the insulation material's ends, causing burn damage at high temperatures. Because insulation materials are expensive, frequent damage necessitates more frequent replacements, inevitably increasing operating costs. Therefore, there is an urgent need to extend the service life of insulation materials to reduce operating costs. Utility Model Content

[0003] The purpose of this utility model is to provide a protective device for thermal insulation materials to solve the problems existing in the prior art.

It significantly reduces the cost of use, and connects the two protective structures with connectors to form an integral structure that fully protects the thermal insulation materials, ensuring the effectiveness of the protection.

[0004] To achieve the above objectives, this utility model provides the following solution: This utility model provides a protective device for thermal insulation materials, comprising: Two protective structures are provided, which cover both sides of the vulnerable area of ​​the insulation material along the thickness direction of the insulation material.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] The purpose of this utility model is to provide a protective device for thermal insulation materials to solve the problems existing in the prior art. It solves the problem that in equipment using thermal insulation materials, the materials are easily damaged by high-temperature fluid impact, material collision, scraping, and falling particles, which can lead to high-temperature burning. It significantly reduces the cost of use, and connects the two protective structures with connectors to form an integral structure that fully protects the thermal insulation materials, ensuring the effectiveness of the protection.

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] like Figures 1 to 9 As shown, this utility model provides a protective device for thermal insulation material, including a connector 4 and two protective structures 2; wherein the two protective structures 2 cover both sides of the vulnerable area 8 of the thermal insulation material 1 along the thickness direction of the thermal insulation material 1; the connector 4 penetrates the two protective structures 2 and the thermal insulation material 1 along the thickness direction of the thermal insulation material 1, and the two ends of the connector 4 are respectively connected to the corresponding protective structures 2. In the protective device for insulation material 1 disclosed in this utility model, firstly, the protective structure 2 covers the insulation material 1, which can effectively withstand mechanical impact and prevent the accumulation and burning of high-temperature particles, significantly extending the service life of the insulation material 1. This solves the problem in the prior art that the insulation material 1 is easily damaged by high-temperature fluid impact, material collision, scraping, and particle falling in equipment, resulting in high-temperature burning. This significantly reduces the cost of use, thereby improving the stability of the equipment and greatly enhancing the quality and batch stability of sintered products. Secondly, two protective structures 2 cover both sides of the vulnerable area 8 and are connected by connectors 4 to form an integral structure that fully protects the insulation material 1, ensuring the effectiveness of the protection and preventing damage to the insulation material 1 caused by external influences during the protection process.

[0021] To ensure that the entire protective device can be used in high-temperature environments, such as in heating equipment like vacuum degreasing sintering furnaces, hard alloy furnaces, and heat treatment furnaces, in this embodiment, preferably, the protective structure 2 is made of carbon-carbon composite material or graphite and other high-temperature and high-pressure resistant materials, but is not limited to the above two materials. Furthermore, the connector 4 is made of carbon-carbon composite material or graphite and other high-temperature and high-pressure resistant materials, but is not limited to the above two materials either.

[0022] Furthermore, to improve the ease of replacing the protective structure 2, in one specific embodiment, the two ends of the connector 4 are detachably connected to the corresponding protective structure 2, so as to ensure that when the protective structure 2 reaches its expected lifespan, the connector 4 can be easily separated from the protective structure 2, thereby facilitating its replacement.

[0023] In one embodiment, the entire protective device also includes two pressing structures 5. Each pressing structure 5 is connected to the two ends of the connector 4 at the positions extending out of the respective protective structures 2, and is pressed onto the corresponding protective structures 2. By setting the two pressing structures 5, the two protective structures 2 can be pressed tightly onto both sides of the insulation material 1, ensuring the effectiveness of the protection of the insulation material 1 and avoiding interference from the external environment, which would cause the protective structure 2 to be less effective in protecting the insulation material 1. The pressing structures 5 can be detachably installed on the connector 4, including threaded connections or snap-fit ​​connections.

[0024] In this embodiment, the connector 4 adopts a bolt structure. The nut of the bolt structure serves as a crimping structure 5 and is crimped onto a protective structure 2. A nut is connected to the end of the bolt structure away from the nut. The nut is crimped onto another protective structure 2, so that the two protective structures 2 are pressed tightly onto both sides of the insulation material 1 through the nut and nut structure. Its structure is simpler, the materials are readily available, and the cost is low.

[0025] Furthermore, the entire protective device also includes a sealing structure, which is sealed at the positions where each connector 4 connects to the corresponding protective structure 2, to ensure the tightness of the protection of the insulation material 1, fully preventing the insulation material 1 from being easily damaged by external environmental influences, thereby fully extending the service life of the insulation material 1.

[0026] To improve the airtightness of the protection for the insulation material 1, in this embodiment, each end of the connector 4 extending out of the protective structure 2 is connected to a pressing structure 5, and each pressing structure 5 is pressed onto the corresponding protective structure 2. The sealing structure uses a sealing gasket 3, which is sleeved on the outer periphery of the connector 4 and pressed between the pressing structure 5 and the protective structure 2. The sealing gasket 3 cooperates with the pressing structure 5 to press into the gap between the connector 4 and the protective structure 2. By fully deforming itself after being pressed, it can fully fill the gap and improve the protection effect for the insulation material 1.

[0027] The sealing gasket 3 can be a single piece, so that each connector 4 can pass through the sealing gasket 3. The sealing gasket 3 can also be multiple pieces, each corresponding to a connector 4.

[0028] For the selection of the sealing structure, high-temperature and high-pressure resistant sealing structures such as graphite paper gaskets can be used, enabling them to withstand high temperatures and pressures and adapt to the application environment, thus providing long-term protection for the insulation material 1. High-temperature and high-pressure resistant sealants can also be used to fill the gap between the connector 4 and the protective structure 2.

[0029] In another case, for the detachable connection between the connector 4 and the protective structure 2, the two ends of the connector 4 can be directly connected to the protective structure 2. For example, the protective structure 2 is a rigid structure with threaded through holes, and the connector 4 is a straight rod structure with threaded structures at both ends, so that the two ends of the connector 4 can be directly connected to the corresponding threaded through holes.

[0030] The vulnerable area 8 includes, but is not limited to, the location of the insulation material 1 that is subject to fluid erosion, the location that needs repair after damage, and the location that is easily impacted or scratched. For example, in high-pressure equipment, part of the structure of the insulation material 1 corresponds to the location of the high-pressure airflow outlet 7. The high-pressure airflow can easily damage this location of the insulation material 1, so this location of the insulation material 1 is the vulnerable area 8. Alternatively, when the insulation material 1 is damaged, the insulation filling material 6 is filled into the damaged area of ​​the insulation material 1, so this location is also the vulnerable area 8. The protective structure 2 is fixed to the vulnerable area 8 of the insulation material 1 to improve the service life of the insulation material 1.

[0031] In this embodiment, as a preferred example, both protective structures 2 are plate-shaped structures and are respectively matched with the surface structures on both sides of the vulnerable area 8. They cover and adhere to the surface on both sides of the vulnerable area 8, so that the plate-shaped structure of the protective structure 2 can match the corresponding structure of the insulation material 1, such as the surface of the insulation material 1 with a planar structure, or the protective structure 2 is an arc-shaped plate-shaped structure to match the arc-shaped structure of the insulation material 1, thereby better matching the surface of the vulnerable area 8 and forming an effective adhesive protection for the insulation material 1.

[0032] As another preferred example, the insulation material 1 has a cylindrical port, which is a vulnerable area 8. The two protective structures 2 are equipped with end plate structures, which are connected between the two protective structures 2 and form an annular groove structure. The cylindrical port is tightly embedded in the annular groove structure to provide sufficient protection for the port of the insulation material 1. The structure of the port is not limited to a cylindrical structure or a square hole structure, etc.

[0033] For ease of installation, the annular groove structure includes multiple splicing parts, which are distributed and spliced ​​together along the circumference of the port of the insulation material 1, and can be matched with ports of different shapes.

[0034] As another preferred example, the insulation material 1 has an edge structure, which is a vulnerable area 8. The protective structure 2 has a folded edge structure and is fastened to the corresponding edge structure to effectively protect the edge structure of the insulation material 1.

[0035] Any adaptive changes made according to actual needs are within the protection scope of this utility model.
