Description

Technical Field

[0001] This utility model relates to the field of flange protection technology, and in particular to a structure for an anti-splash flange protective cover for high-temperature scraper equipment. Background Technology

[0002] In high-temperature processes in industries such as chemical, pharmaceutical, and food processing, high-temperature scraper equipment serves as a core component in material handling, responsible for conveying and scraping high-temperature, high-pressure materials. The equipment's cylinder and top cover are connected by flanges. This connection is subjected to prolonged high-temperature, high-pressure conditions, making it susceptible to seal failure due to aging of the seals and thermal expansion and contraction of the bolts. This can lead to leakage of high-temperature, high-pressure materials from the flange gaps, causing them to spray outwards.

[0003] The flange connection of existing high-temperature scraper equipment generally does not have a dedicated anti-splash protection structure. Leakage and spray not only cause material waste and contaminate the equipment and surrounding devices, but also directly threaten the personal safety of operators due to the high temperature of the material. Furthermore, the splashed material adhering to the equipment or adjacent devices will accelerate the corrosion and aging of components and shorten the service life of the equipment. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a splash-proof flange protective cover structure for high-temperature scraper equipment, which can effectively prevent high-temperature liquid from leaking from the flange connection, ensuring the personal safety of operators and extending the service life of the equipment.

[0005] The above-mentioned utility model objective is achieved through the following technical solution:

[0006] A splash-proof flange protection cover structure for a high-temperature scraper equipment is installed at the connection between the upper cover and the flange of the high-temperature scraper equipment. It includes a circumferentially non-enclosed protective cover plate. The upper side of the protective cover plate is fixedly connected to the outer peripheral wall of the upper cover and extends downward to cover the sealing connection area between the upper cover and the flange.

[0007] The above technical solution utilizes a circumferentially non-enclosed protective cover to avoid the pipeline connected to the flange, while the downward-extending protective cover directly blocks the flange sealing area, initially preventing leaked materials from splashing in all directions. This provides basic anti-splash protection for the flange of the high-temperature scraper equipment, preventing material spray from contaminating the equipment or injuring personnel.

[0008] As a further technical solution of this utility model: the protective cover plate is an arc-shaped structure concentric with the outer peripheral wall of the upper cover.

[0009] The above technical solutions ensure that the protective cover plate fits precisely to the circumference of the equipment, guaranteeing that the flange sealing area is uniformly and without blind spots. At the same time, the arc shape provides a stable arc-shaped guide surface for the directional flow of leaked materials, avoiding flow confusion caused by misalignment of the cover plate.

[0010] As a further technical solution of this utility model: the upper side of the protective cover plate is fixedly connected to the outer peripheral wall of the upper cover by welding.

[0011] By utilizing the high strength and high temperature resistance of welding, the connection between the protective cover and the top cover is ensured to be stable under high temperature conditions, avoiding loosening or falling off due to high temperature, ensuring the long-term reliability of the protective cover's anti-splash function, and improving the equipment's adaptability to high temperature environments.

[0012] As a further technical solution of this utility model: the inner wall of the protective cover is a smooth curved surface.

[0013] The above technical solutions reduce the resistance of leaked material inside the protective cover, allowing the material to flow smoothly down the curved surface. This avoids material accumulation and agglomeration that could affect the flow efficiency, reduces the difficulty of subsequent cleaning, and lowers equipment maintenance costs.

[0014] As a further technical solution of this utility model: the protective cover extends downward to the radial outer side of the flange and covers the outer area of ​​the sealing surface between the upper cover and the flange.

[0015] The above technical solution ensures that the protective cover covers the entire risk area of ​​flange seal leakage, preventing material from leaking from the flange edge due to insufficient extension of the protective cover, further enhancing the comprehensiveness of splash prevention, and eliminating the possibility of leaked material contaminating surrounding equipment components.

[0016] As a further technical solution of this utility model: a high-temperature scraper device, including a cylinder, a flange and a top cover, wherein the device is provided with an anti-splash flange protective cover structure as described in any one of the claims.

[0017] The above technical solutions enable high-temperature scraper equipment to have anti-splash flange protection, preventing high-temperature liquid from leaking from the flange connection, improving equipment operation safety, reducing material waste and surrounding pollution, ensuring personal safety and extending equipment service life.

[0018] In summary, this utility model has at least one of the following beneficial technical effects:

[0019] 1. This utility model discloses a splash-proof flange protective cover structure for high-temperature scraper equipment.

[0020] 2. This utility model discloses a splash-proof flange protective cover structure for high-temperature scraper equipment. By adopting a concentric arc, smooth curved surface and welded fixing structural design, it achieves a stable fit between the protective cover and the equipment and efficient airflow, ensuring the reliability, long-term effectiveness and ease of maintenance of the protection.

[0021] 3. This utility model discloses a splash-proof flange protective cover structure for high-temperature scraper equipment.

[0029] Example 1:

[0030] Reference Figure 1 This utility model discloses a splash-proof flange protective cover structure for a high-temperature scraper equipment. It is installed at the connection between the upper cover 4 and the flange 2 of the high-temperature scraper equipment and includes a circumferentially non-enclosed protective cover plate 3. The protective cover plate 3 is made of a high-temperature resistant metal material, such as stainless steel, heat-resistant steel, or nickel-based alloy, to prevent deformation, corrosion, or breakage under long-term high-temperature conditions, ensuring the service life and functional stability of the protective structure. Simultaneously, the protective cover plate 3 adopts a circumferentially non-enclosed design. The opening formed by its non-enclosed portion must be adapted to the shape of the pipe connected to the flange 2, and the edges of the opening are rounded to avoid sharp edges scratching operators or abrading the outer wall of the pipe, and also to prevent leaked material from accumulating and agglomerating at the corners of the opening. This ensures that the protective cover plate 3 avoids the pipe while not affecting the original material conveying function of the equipment.

[0031] The thickness of the protective cover plate 3 is set according to the material impact intensity during equipment operation, the coverage area of ​​the protective cover and the load-bearing requirements of the equipment. The thickness is kept uniform along the extension direction to avoid uneven deformation under stress, ensuring that it has both sufficient impact resistance and lightweight, without increasing the extra load on the equipment.

[0032] Reference Figure 1 and Figure 2 The protective cover 3 is an arc-shaped structure concentric with the outer peripheral wall of the upper cover 4. This arc-shaped structure can closely fit the circumference of the high-temperature scraper equipment and form a uniform and blind-spot-free annular shield over the sealing connection area between the upper cover 4 and the flange 2, preventing materials from splashing from the gap between the cover and the equipment.

[0033] Reference Figure 1 The upper side of the protective cover plate 3 is fixedly connected to the outer peripheral wall of the upper cover 4 by welding. The welded connection has the characteristics of high strength and high temperature resistance, which can adapt to the high temperature working conditions of the high temperature scraper equipment for a long time. It effectively prevents the protective cover plate 3 from loosening or falling off under the action of thermal expansion and contraction, and ensures the long-term stability of the protective function.

[0034] Meanwhile, the inner wall of the protective cover plate 3 needs to be polished to form a smooth curved surface. This curved surface structure can significantly reduce the frictional resistance between the leaked material and the inner wall of the cover plate, allowing the material to flow smoothly downwards along the curved surface. This not only prevents the material from accumulating and clumping, affecting the flow efficiency, but also reduces the subsequent cleaning workload and maintenance costs of the protective cover plate 3.

[0035] In addition, refer to Figure 1 and Figure 3 The length of the protective cover plate 3 extending downward is based on the lower end of the flange sealing surface between the upper cover 4 and the flange 2. It is reasonably set according to the overall size of the equipment, the flange specifications and the range of material leakage risk to ensure that it can completely cover the entire risk area where the flange 2 seal may leak, including the edge of the sealing surface between the flange 2 and the upper cover 4, the gap of the bolt connection and other easily leaking parts, so as to prevent material from leaking from the edge of the flange 2 due to insufficient extension of the cover plate.

[0036] This utility model also protects a high-temperature scraper device integrating the anti-splash structure. The device includes a cylinder 1, a flange 2, and a top cover 4. During assembly, the flange 2 is first fixedly connected to the upper end of the cylinder 1 by bolts or welding and other conventional connection methods in the art. Then, the top cover 4 is sealed to the flange 2 by bolts. Finally, the anti-splash flange cover is installed at the connection between the top cover 4 and the flange 2. The entire assembly process does not require major modifications to the main structure of the device, such as the cylinder 1 and the top cover 4, and is suitable for the upgrading of existing high-temperature scraper devices and the mass production needs of new devices.

[0037] The working process of this utility model's anti-splash flange protective cover structure for high-temperature scraper equipment is as follows: When the flange sealing surface fails during the operation of the high-temperature scraper equipment, the high-temperature material inside the equipment sprays outward from the point of seal failure. At this time, the circumferentially non-enclosed protective cover plate 3 directly blocks the leaked material from splashing in all directions with its downwardly extending arc-shaped shielding part, preventing the material from accidentally injuring operators or contaminating adjacent equipment; the blocked leaked material contacts the smooth inner curved surface of the protective cover plate 3 under the action of gravity. Due to the low friction characteristics of the smooth curved surface, the material flows naturally downward along the inner wall. This achieves directional flow guidance; at the same time, the welding connection between the protective cover plate 3 and the outer peripheral wall of the upper cover 4 ensures the stability of the connection point in a high-temperature environment, preventing the protective cover plate 3 from shifting or falling off due to vibration or high temperature, and ensuring the continuous effectiveness of the protective function; moreover, the full coverage design of the protective cover plate 3 over the flange sealing area can eliminate blind spots in protection, and even if materials seep out from the edge of the flange sealing surface or the bolt gap, they can be controlled inside the cover; finally, the leaked material is discharged to the designated collection area along the smooth curved wall inside the protective cover plate 3 according to a predetermined path, realizing the integrated function of splash prevention and safe flow guidance.

[0038] The implementation principle of this utility model is as follows: A circumferentially non-enclosed protective cover plate 3 achieves the dual functions of avoiding connected pipes and fully shielding the sealing area. Its concentric arc design ensures that the protective cover plate 3 conforms to the equipment's shape, eliminating installation errors and blind spots; the smooth curved surface improves material flow characteristics, preventing accumulation and blockage; welding fixation gives the overall structure excellent high-temperature mechanical strength and vibration resistance; the extended coverage design prevents material from overflowing radially from the flange. This structure improves the level of seal failure protection under high-temperature conditions without significantly altering the original equipment connection method, combining structural simplicity and ease of maintenance. It is suitable for various splash protection applications requiring flange 2 connections for high-temperature equipment.

[0039] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
