Description

Technical Field

[0001] This utility model relates to a top reinforcement structure, specifically a top reinforcement structure for a high-temperature dust collector. Background Technology

[0002] The top reinforcement structure of a high-temperature dust collector is designed to enhance the mechanical strength and heat resistance of the collector's top, preventing deformation or damage under high temperature and pressure conditions. Existing high-temperature dust collector top reinforcement structures use three steel plates welded together. The drawbacks of this structure are as follows:

[0003] 1. Stress Concentration: Due to the discontinuity of the geometry at welded joints, stress concentration is prone to occur. Especially at the interface between the weld and the base material, this stress concentration may lead to localized yielding or fracture of the material.

[0004] 2. Welding defects: During the welding process, defects such as porosity, slag inclusions, incomplete penetration, and lack of fusion may occur. These defects will reduce the mechanical properties of the weld, especially at high temperatures, where they are more likely to lead to brittle fracture of the material.

[0005] 3. Thermal stress: Due to the static air gap between the reinforcing ring and the shell, the heat transfer effect is poor, resulting in a large temperature difference between the two. This temperature difference will cause differences in thermal expansion, thus generating thermal stress, which can easily cause cracks at the weld.

[0006] 4. Poor fatigue performance: The reinforcing ring does not form a unified whole with the shell or connecting pipe metal, resulting in poor fatigue performance. Under long-term high temperature and pressure, fatigue cracks may appear at the weld.

[0007] 5. Increased rigidity: When the reinforcing ring is welded to the shell, the rigidity at this point increases, which has a greater restraining effect on the cooling and shrinkage of the fillet weld, making it easier to cause cracks at the weld.

[0008] 6. High maintenance difficulty: Once defects or damage occur at the weld, repair is relatively difficult, requiring the removal of part of the structure for repair, which increases maintenance costs and time.

[0009] In summary, this utility model presents a novel top reinforcement structure for a high-temperature dust collector. Utility Model Content

[0010] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a top reinforcement structure for a high-temperature dust collector. The structure is reasonably designed, uses large steel plates to supplement the structural strength, reduce the risk of leakage, improve high-temperature performance, corrosion resistance, and sealing performance, and is highly practical.

[0011] To achieve the above objectives, this utility model is implemented through the following technical solution: a top reinforcement structure for a high-temperature dust collector, including an upper housing, a lifting valve is provided between the upper housings, multiple transverse flat steel bars are provided on the top of the upper housing, multiple parallel longitudinal flat steel bars are provided on the outer side of the transverse flat steel bars, a first steel plate is provided at the connection between the transverse flat steel bars and the longitudinal flat steel bars, a first steel plate is also provided at the end of the longitudinal flat steel bars, and a second steel plate is provided at the outer end of the transverse flat steel bars and at the four corners of the upper housing.

[0012] Preferably, the first steel plate is convex in shape.

[0013] Preferably, the second steel plate is L-shaped.

[0014] Preferably, the first steel plate and the second steel plate are welded to the top of the upper housing.

[0015] Preferably, the first steel plate and the second steel plate are fixed to the top of the upper housing by bolts and high-temperature resistant screw glue.

[0016] Preferably, the bottom of the upper housing is provided with multiple inspection ports, and the inspection ports are provided with handles on their inspection covers.

[0017] Preferably, both the first steel plate and the second steel plate are Q345R steel plates.

[0018] Preferably, both the first steel plate and the second steel plate are top compensation plates for a high-temperature dust collector.

[0019] The beneficial effects of this utility model are as follows: This utility model changes the traditional top reinforcement structure of a high-temperature dust collector from three welded steel plates to a single steel plate, which has the following advantages:

[0020] 1. Increased strength: The structural integrity of the entire steel plate is higher, reducing the number of welding points and thus increasing overall strength. Welding points are often weak points in the structure, prone to cracking or breakage.

[0021] 2. Reduce leakage risk: The more weld points there are, the greater the risk of leakage. Using a single piece of steel plate can significantly reduce the number of welds, thereby reducing the possibility of gas or dust leaking from the welds.

[0022] 3. Simplified Manufacturing Process: Using a single piece of steel simplifies the manufacturing and assembly process, reduces welding steps, and improves production efficiency. This not only saves time and labor costs but also reduces quality problems caused by improper welding.

[0023] 4. Improved high-temperature resistance: The entire steel plate is more stable in high-temperature environments and is less prone to deformation or damage due to uneven heating in certain areas. Welded joints may experience thermal stress concentration at high temperatures, leading to material fatigue or cracking.

[0024] 5. Enhanced corrosion resistance: Welded areas are often more susceptible to corrosion. Using a single piece of steel can reduce these potential corrosion points, thereby extending the service life of the equipment.

[0025] 6. Improved sealing: The solid steel plate provides better sealing, preventing dust and gas leakage and ensuring efficient operation of the dust collector.

[0026] In summary, changing the top reinforcement structure of the high-temperature dust collector from three welded steel plates to a single steel plate can significantly improve the equipment's performance and reliability, extend its service life, and reduce maintenance costs.

[0032] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0033] Reference Figure 1-4 The specific implementation adopts the following technical solution: a top reinforcement structure for a high-temperature dust collector, including an upper housing 1, with a lifting valve 2 between the upper housing 1, multiple transverse flat steels 3 on the top of the upper housing 1, multiple parallel longitudinal flat steels 4 on the outer side of the transverse flat steels 3, a first steel plate 5 at the connection between the transverse flat steels 3 and the longitudinal flat steels 4, a first steel plate 5 at the end of the longitudinal flat steels 4, and a second steel plate 6 at the outer end of the transverse flat steels 3 and the four corners of the upper housing 1.

[0034] It is worth noting that the first steel plate 5 is convex in shape.

[0035] It is worth noting that the second steel plate 6 is L-shaped.

[0036] It is worth noting that the first steel plate 5 and the second steel plate 6 are welded to the top of the upper box.

[0037] It is worth noting that the first steel plate 5 and the second steel plate 6 are fixed to the top of the upper box body by bolts and high-temperature resistant screw glue.

[0038] It is worth noting that the bottom of the upper housing 1 is also provided with multiple inspection ports 7, and the inspection ports 7 are provided with handles 8 on their inspection covers.

[0039] It is worth noting that the first steel plate 5 and the second steel plate 6 are both Q345R steel plates. This material has good strength and toughness, as well as high temperature resistance, and is suitable for top reinforcement of high temperature dust collectors.

[0040] In addition, the first steel plate 5 and the second steel plate 6 are both top compensation plates of the high-temperature dust collector.

[0041] In this specific embodiment, the upper casing of the high-temperature dust collector serves as the main load-bearing component, possessing sufficient strength and high-temperature resistance. A lifting valve controls the airflow, ensuring pressure balance within the dust collector. Multiple transverse and longitudinal flat steel bars are installed at the top of the upper casing 1, forming a grid-like support structure, enhancing the rigidity and stability of the upper casing. The first steel plate 5 is located at the connection between the transverse flat steel 3 and the longitudinal flat steel 4, providing reinforcement. Its convex design increases the contact area and improves connection strength. The second steel plate 6 is located at the outer end of the transverse flat steel 4 and at the four corners of the upper casing 1, further enhancing the overall structural stability. Its L-shaped design better disperses stress. Inspection ports 7 and handles 8 facilitate inspection and maintenance of the dust collector's interior, improving maintainability. Bolts and high-temperature resistant threadlocker adhesive are used to secure the first steel plate 5 and the second steel plate 6, ensuring a firm and reliable connection.

[0042] This specific embodiment significantly improves the rigidity and stability of the upper housing by incorporating transverse and longitudinal flat steel bars, as well as a first and second steel plate, reducing potential deformation and damage under high-temperature conditions. The use of Q345R steel plates and high-temperature resistant threadlocker ensures the reliability and durability of the structure under high-temperature conditions. The inclusion of inspection ports and handles facilitates inspection and maintenance of the dust collector's interior, improving maintainability and operational efficiency. The special shape design of the first and second steel plates (convex and L-shaped) better disperses stress, preventing structural damage caused by localized stress concentration. Installation is simple: fixing is achieved with bolts and high-temperature resistant threadlocker, making the installation process quick and easy, reducing construction difficulty and cost.

[0043] In summary, the top reinforcement structure of this high-temperature dust collector, through reasonable material selection and structural design, effectively improves the overall strength and high-temperature resistance of the dust collector, ensuring stable operation of the equipment in high-temperature environments.
