Description

Technical Field

[0001] This utility model relates to the field of high-temperature centrifugal fan technology, and in particular to a high-temperature centrifugal fan that is easy to assemble and disassemble. Background Technology

[0002] High-temperature centrifugal fans are widely used in industries such as metallurgy, chemical engineering, and power generation, primarily for transporting gases in high-temperature environments. However, these fans operate under harsh conditions for extended periods, often involving high temperatures, corrosive gases, or dust, making critical components such as the impeller and casing highly susceptible to wear and corrosion.

[0003] Traditional high-temperature centrifugal fans require complete disassembly for component maintenance, a cumbersome and time-consuming process that leads to prolonged downtime and significantly impacts production schedules. In contrast, a modular design for high-temperature centrifugal fans allows for quick and easy assembly and disassembly. Maintenance can be performed on partial parts, requiring only replacement of damaged or vulnerable components, significantly reducing downtime and greatly improving equipment operating efficiency. Furthermore, the modular design's easy disassembly and assembly not only meets the maintenance needs of high-temperature environments but also aligns with the stringent requirements of modern industry for efficiency, cost, and flexibility. It has proven highly effective in improving equipment reliability, reducing maintenance costs, and extending service life, making it an inevitable trend in industrial equipment development.

The transmission side cover plate and the housing are connected by bolts to form an accommodating space. One end of the transmission assembly is connected to the transmission side cover plate, and the other end is connected to a belt shaft driven by a motor module.

[0008] The impeller module is located inside the housing, and the shaft of the impeller module is connected to the transmission assembly.

[0009] The protective cover module includes a belt cover, which is a split structure with one end fixed to the transmission group bracket by bolts, and the other end connected to the protective cover fixing frame and fixed to the fan base by bolts.

[0010] The motor module includes a motor, a motor mounting base, and motor locking components. The motor mounting base is welded to the fan base and has elongated holes for adjusting the position of the motor. The motor locking components are symmetrically arranged on both sides of the motor.

[0027] like Figure 1-3 As shown, a high-temperature centrifugal fan that is easy to assemble and disassemble includes a housing module, a transmission module, an impeller module, a protective cover module, and a motor module.

[0028] The housing module includes a spiral-shaped housing 7 with the air outlet facing upwards and a fan base 5. Two clamping plates are fixed between the housing 7 and the fan base 5 to support the housing 7. Two clamping plates are provided, vertically and symmetrically arranged on both sides of the housing 7. The upper end of the clamping plates is connected to the housing 7 by bolts, and the lower end is connected to the fan base 5 by bolts, which is used to raise the fan 7. An air inlet 8 is bolted to the front opening of the housing 7.

[0029] The transmission module includes a transmission group 6 and a transmission group bracket 4. The transmission group 6 is a rotating shaft fixed on the transmission group bracket 4. One end passes through the center of the transmission side cover plate 1 and is connected to the rotating shaft of the impeller. The other end is connected to the belt rotating shaft driven by the motor module.

[0030] The transmission assembly bracket 4 is connected to the fan base 5 by bolts. A support frame 2 connects the transmission side cover plate 1 to the transmission assembly bracket 4. The transmission side cover plate 1 and the casing 7 are connected by bolts to form a receiving space. The support frame 2 not only provides reliable support but also ensures the stability of the casing, reducing the risk of excessive fan vibration. The transmission assembly bracket 4 is symmetrically arranged on both sides of the transmission assembly 6, employing a bent plate structure to reduce weight while maintaining bracket strength.

[0031] The impeller module is housed inside the casing 7, and its shaft is connected to the transmission assembly 6. The transmission assembly 6 passes through the center of the transmission side cover plate 1 and is detachably connected to the impeller's shaft. The transmission side cover plate 1 is also detachably connected to the casing 7. The impeller module can be removed entirely from the transmission assembly 6 after the transmission side cover plate 1 is removed, without needing to disassemble the already sealed air inlet and outlet ports. This facilitates maintenance and allows for easy replacement of faulty components.

[0032] The protective cover module includes a belt cover 3, which is a split structure with one end fixed to the transmission group bracket 4 by bolts, and the other end connected to the cover fixing frame 9 and fixed to the fan base 5 by bolts. The belt cover 3 is also provided with a belt inspection port and heat dissipation holes to facilitate belt maintenance and replacement.

[0033] The motor module includes a motor, a motor mounting base 11, and a motor locking component 10. The motor mounting base 11 is welded to the fan base 5. The motor mounting base 11 has an elongated hole for adjusting the position of the motor. The motor locking component 10 is symmetrically arranged on both sides of the motor to facilitate the fixing of the motor position after the belt tensioning is adjusted.

[0034] High-temperature resistant rubber sealing rings are provided at the connection between the housing 7 and the transmission side cover 1, and at the connection between the housing 7 and the air inlet 8.

[0035] Each module of this high-temperature centrifugal fan can be independently disassembled and installed. During maintenance, only the damaged module needs to be replaced or repaired, without disassembling the entire fan. This significantly shortens maintenance time and improves equipment maintainability. It also reduces downtime caused by maintenance, allowing the centrifugal fan to operate stably for longer periods, thereby improving the overall operating efficiency of the production system. The modular design makes it easier to replace vulnerable parts, and standardized components reduce procurement costs, while also reducing maintenance workload and labor costs.

[0036] like Figure 4 As shown, the installation steps for each module are as follows:

[0037] First, the casing 7 and the air inlet 8 are fixed to the fan base 5 with bolts. The transmission assembly 6 and the transmission side cover plate 1 are then installed with the impeller in sequence. The transmission assembly bracket 4 and the fan base 5 are connected with bolts. Then, the transmission assembly 6 and the transmission side cover plate 1 are fixed to the transmission assembly bracket 4 after installation with the impeller. The support frame 2 is fixed between the transmission side cover plate 1 and the transmission assembly bracket, thus completing the installation of the centrifugal fan body.

[0038] Then the belt guard 3 is installed on the guard fixing frame 9 with bolts, and the guard fixing frame 9 is welded to the fan base 5.

[0039] Finally, the motor is installed on the motor mounting base 11, and the motor is adjusted and locked using the motor locking component 10.

[0040] It should be noted that the above embodiments are only used to illustrate the present utility model, but the present utility model is not limited to the above embodiments. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
