TECHNICAL FIELD
[0001] The utility model relates to a forklift silencer heat preservation and thermal insulation field, especially in a kind of silica gel heat preservation and thermal insulation cover material structure for forklift silencer. BACKGROUND
[0002] In the forklift technical field, silencer is a key component, and a large amount of heat will be generated in its working process.Effective heat insulation measures are crucial for the safe operation of forklift, performance improvement and protection of surrounding components.
[0003] In the prior art, the existing forklift silencer heat insulation generally adopts metal mesh plate isolation measures, which is generally only applicable to situations where the temperature requirement is not high, or used on external forklift silencers, and only plays a role in heat insulation and anti-scalding.In addition, the silencer heat insulation cover has a large space, which has a great impact on the space of compact internal combustion forklifts.In addition, the silica gel composite material commonly used in the market is silica cloth + glass fiber cotton + glass cloth, which has poor heat resistance, and the glass cloth is basically ineffective at 600-800℃, and has poor durability on gasoline vehicles.
[0004] Therefore, it is necessary to provide a silica gel heat preservation and thermal insulation cover material structure for forklift silencer to solve the above problems. UTILITY MODEL CONTENT
[0005] The utility model aims to provide a silica gel heat preservation and thermal insulation cover material structure for forklift silencer to solve the problem that metal mesh plate isolation measures are only applicable to situations where the temperature requirement is not high, and only play a role in heat insulation and anti-scalding, and the heat resistance of the silica gel composite material currently used in forklifts is poor.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:
[0007] A silica gel heat preservation and thermal insulation cover material structure for forklift silencer, the heat insulation cover is composed of multiple layers of material and is sewn together, including: silica cloth as the outermost layer, glass fiber cotton as the second layer, ceramic fiber cotton as the third layer, high-silica cloth as the fourth layer, and inner lining 304 stainless steel mesh as the innermost layer.The heat insulation cover can be sewn according to the shape of the silencer or exhaust pipe to closely fit its shape, forming a silica gel heat preservation and thermal insulation cover material structure.
[0008] Preferably, the measured temperature on the outside of the silica cloth does not exceed 100℃ during use to meet the use requirements of most working conditions.
[0009] Preferably, the silica cloth has a thermal conductivity coefficient of ≤0.04 at room temperature, a tensile strength of 0.72Mpa, a non-combustibility of A level, and a heat resistance of up to 550°C, to ensure the safety and stability of the heat insulation cover in high temperature environment.
[0010] Preferably, the temperature resistance range of the ceramic fiber cotton and high silica cloth is 850-1000℃.
[0011] Preferably, the ceramic fiber cotton and high silica cloth work together to provide high temperature resistance for the heat shield to adapt to the high temperature environment of the forklift muffler under different working conditions.
[0012] Preferably, the glass fiber cotton is used to enhance the heat insulation effect of the heat shield, and works together with other layers of materials to improve the overall heat insulation performance.
[0013] Preferably, the inner lining of stainless steel wire mesh prolongs the service life of the heat shield when it is in contact with other components or affected by external factors through its wear-resistant properties, reducing damage caused by wear.
[0014] The technical effects and advantages of the utility model are as follows:
[0015] 1. The actual measured temperature on the outer side of the outermost layer of the heat shield does not exceed 100℃ during use, which can effectively prevent the heat of the muffler from being dissipated outward, and meets the strict requirements of most working conditions for heat insulation. This not only protects the forklift operator from the risk of high temperature scalding, but also reduces the impact of heat on the surrounding components of the forklift, reducing the possibility of performance degradation or damage of other components caused by high temperature, thereby improving the stability and reliability of the overall operation of the forklift;
[0016] 2. The composite structure of multiple layers of different materials, especially the glass fiber cotton, enhances the heat insulation effect, and the layers of materials work together to form an efficient heat insulation system. Compared with the traditional metal mesh plate heat insulation method, the heat insulation performance has undergone a qualitative leap;
[0017] 3. The heat resistance temperature of the silica cloth is 550°C, the temperature resistance range of the ceramic fiber cotton is 850-1000℃, and the temperature resistance range of the high silica cloth is 850-1000℃. This combination of materials basically covers the high temperature range that the muffler of gasoline and diesel vehicles may reach during operation, and can adapt to the high temperature environment of the forklift muffler under various complex working conditions. Whether it is long-term high-load operation or instantaneous high-temperature impact under special working conditions, the heat shield can maintain stable heat insulation performance, effectively protect the muffler and surrounding components, and prolong their service life;
[0018] 4. The non-combustible silica cloth is A-level, and the entire heat shield is made of A-level non-combustible material, which can withstand high temperatures of 550℃. This greatly reduces the risk of fire and meets the strict requirements of forklifts in industrial environments for safety and environmental protection. The heat shield can be tailored and sewn according to the shape of the muffler or exhaust pipe, tightly fitting its shape. This customized design ensures that there is no gap between the heat shield and the muffler, minimizing heat loss through air convection and other means, further improving the heat insulation effect.

[0021] 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.
[0022] This utility model provides, for example Figure 1 The diagram shows a silicone thermal insulation cover material structure for a forklift muffler. The thermal insulation cover is made of multiple layers of composite materials, including: an outermost layer of silicone cloth 1, a second layer of glass fiber cotton 2, a third layer of ceramic fiber cotton 3, a fourth layer of high silica cloth 4, and an innermost lining of 304 stainless steel wire mesh 5. The thermal insulation cover can be woven and sewn according to the shape of the muffler or exhaust pipe to fit its shape tightly, thus forming a silicone thermal insulation cover material structure.
[0023] Based on the specific dimensions of the forklift muffler, each layer of material is precisely cut. First, the silicone cloth 1 is cut, slightly larger than the surface area of the muffler to facilitate subsequent sewing and bonding. Then, fiberglass wool 2, ceramic fiber wool 3, high-silica cloth 4, and 304 stainless steel wire mesh lining 5 are cut sequentially, ensuring each layer maintains the same size and fits the silicone cloth 1. The cut layers are then neatly stacked in the order of silicone cloth 1, fiberglass wool 2, ceramic fiber wool 3, high-silica cloth 4, and 304 stainless steel wire mesh lining 5, and sewn using professional sewing equipment and high-temperature resistant thread. During sewing, it is ensured that each layer of material fits tightly, with fine and even stitches, avoiding gaps or misalignment. Special treatments are applied to the sewn edges, such as binding or denser sewing, to enhance the overall strength and sealing of the heat insulation cover.
[0024] The measured temperature of the outer side of the silicone cloth 1 does not exceed 100°C during use, which meets the requirements of most working conditions. The silicone cloth 1 has a thermal conductivity of ⩽0.04 at room temperature, a tensile strength of 0.72 MPa, a non-flammability rating of Class A, and a heat resistance temperature of up to 550°C, which is used to ensure the safety and stability of the heat insulation cover in high-temperature environments.
[0025] The multi-layered composite structure works synergistically to form a highly efficient thermal insulation barrier. The outermost layer, silicone cloth 1, has a low thermal conductivity at room temperature (⩽0.04), effectively preventing heat transfer. Glass fiber cotton 2 further enhances the insulation effect and reduces heat conduction.
[0026] The glass fiber cotton 2 is used to enhance the heat insulation effect of the heat insulation cover. It works together with other materials to improve the overall heat insulation performance. The temperature resistance range of the ceramic fiber cotton 3 and the high silica cloth 4 is 850-1000℃. The ceramic fiber cotton 3 and the high silica cloth 4 work together to provide the heat insulation cover with high temperature resistance to adapt to the high temperature environment of the forklift muffler under different working conditions.
[0027] Silicone cloth 1 has a heat resistance temperature of up to 550°C, ceramic fiber cotton 3 has a temperature resistance range of 850-1000°C, and high-silica cloth 4 also has a temperature resistance range of 850-1000°C. When the forklift muffler generates high temperatures during operation, these high-temperature resistant materials can withstand the high-temperature environment without performance degradation. Whether under prolonged high-load operation or short-term high-temperature peak conditions, the heat shield maintains structural integrity and continuously performs its heat insulation function, ensuring the normal operation of the muffler in high-temperature environments. It also protects surrounding components from high-temperature damage, extends the service life of the entire heat dissipation system, and reduces the risk of failure due to high temperatures.
[0028] The inner lining of 304 stainless steel wire mesh 5, through its wear-resistant properties, extends the service life of the heat insulation cover when it comes into contact with other components or is affected by external factors, and reduces damage caused by wear.
[0029] The innermost lining, made of 304 stainless steel wire mesh 5, possesses excellent wear resistance. During forklift operation, the muffler heat shield may rub against other components or be affected by external factors. The 304 stainless steel wire mesh lining 5 effectively resists this wear, protecting the internal insulation material from damage. This significantly extends the service life of the heat shield, reducing maintenance costs and downtime associated with frequent heat shield replacements, and improving the overall operating efficiency and economy of the forklift. In the long run, this reduces the company's operating costs and enhances the forklift's overall value.
[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
