Technical Field

[0001] The utility model belongs to the field of fluid mechanics, and particularly relates to a high-temperature resistant high-pressure mixed-flow fan. Background Art

[0002] A high-pressure mixed-flow fan is an efficient and multi-functional air handling device, mainly used for ventilation and heat treatment in industrial and commercial applications. It combines the characteristics of a centrifugal fan and an axial-flow fan, so it is called a mixed-flow fan. High-pressure mixed-flow fans are usually designed to handle high-temperature and high-pressure air or gas, so they are widely used in occasions such as heat treatment furnaces and industrial drying equipment that require high-efficiency air delivery. They can operate stably in high-temperature environments and maintain high efficiency and energy consumption ratio.

[0003] From the perspective of long-term use, existing high-pressure mixed-flow fans generally work in high-temperature environments, but they generally have a defect that there is no cooling device inside, so the motor often fails due to working for a long time under high-temperature conditions, which greatly increases the cost of later maintenance. Content of the Utility Model

[0004] The purpose of the utility model is to provide a high-temperature resistant high-pressure mixed-flow fan, which can ensure that when the motor generates heat during operation, the hot air inside the motor is discharged in time, reducing the probability of the motor malfunctioning due to high temperature, and solving the problem that the existing technology fans malfunction under high-temperature conditions.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is that the utility model provides a high-temperature resistant high-pressure mixed-flow fan, including a fan. An impeller is arranged inside the fan, guide vanes are arranged around the impeller, a casing is arranged outside the guide vanes, a connecting column is arranged at the rear side of the casing, the impeller is connected to a motor, a connecting device is arranged on one side of the motor, a cooling fan is arranged at the rear side of the motor, a base is arranged at the bottom of the fan, a triangular platform is arranged above the base, a track is arranged on the triangular platform, a collector is arranged above the track, and a control device is arranged on one side of the collector.

[0006] Preferably, there are 4 connecting columns, which are distributed around the casing.

[0007] Preferably, guide vanes are arranged in a circle around the impeller.

[0008] Preferably, a motor is arranged behind the impeller, and the impeller is internally connected to the motor.

[0009] Preferably, a cooling fan is arranged at the rear side of the motor.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] In order to better understand the above-mentioned objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0018] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0019] Embodiment 1, as Figure 1As shown in the figure, a high-temperature resistant high-pressure mixed-flow fan includes a fan 1. Inside the fan 1, an impeller 2 is provided. Around the impeller 2, guide vanes 3 are arranged. Outside the guide vanes 3, a casing 4 is provided. At the rear side of the casing 4, a connecting column 5 is provided. The impeller 2 is connected to a motor 6. On one side of the motor 6, a connecting device 7 is provided. At the rear side of the motor 6, a cooling fan 8 is provided. At the bottom of the fan 1, a base 9 is provided. Above the base 9, a triangular platform 10 is provided. On the triangular platform 10, a track 11 is provided. Above the track 11, a collector 12 is provided. On one side of the collector 12, a control device 13 is provided.

[0020] Inside the fan 1, an impeller 2 is provided. By rotating, the impeller 2 generates a driving force for the air flow, sucking air from the outside and discharging it towards the target. Around the impeller 2, guide vanes 3 are arranged. The guide vanes 3 are inclined at 45 degrees. When the air passes through, it can timely guide the air entering the fan 1 to enter the impeller 2 in the most effective way. The guide vanes 3 can guide the air flow to the correct inlet angle, reducing unnecessary turbulence and resistance, thereby improving the efficiency and performance of the fan 1. Outside the guide vanes 3, a casing 4 is provided. The casing 4 can protect the impeller 2 and the guide vanes 3, increasing stability. At the rear of the casing 4, a connecting column 5 is provided. The connecting column 5 can connect the casing 4 to the collector 12. Behind the impeller 2, a motor 6 is provided. The motor 6 is connected to the impeller 2 and provides power for the impeller 2. On one side of the motor 6, a connecting device 7 is provided. Inside the connecting device 7, it can be connected to the outside world. External power can supply power to the inside of the motor 6 through the connecting device 7. At the rear side of the motor 6, a cooling fan 8 is provided. When the motor 6 converts energy, always a small part of the loss is converted into heat. This part of the heat must be continuously dissipated through the outer shell of the motor 6 and the surrounding medium. When the motor 6 operates, the cooling fan 8 starts to rotate. The rotation of the cooling fan 8 generates negative pressure, causing the air inside the motor 6 and around it to be blown to a place far away from the motor 6. Through the work of the cooling fan 8, the thermal stress of the internal components of the motor 6 can be reduced, and the service life of the motor 6 can be extended.

[0021] Above the base 9, a triangular platform 10 is provided. The triangular platform 10 provides stable support for the fan 1. The triangular platform 10 is usually made of strong metal or alloy and can bear the weight of the fan itself as well as the forces and vibrations generated during operation. In addition, the triangular platform 10 can ensure that the fan 1 will not shift or tilt due to vibration or instability during operation, ensuring the safety and stability of the fan 1. The triangular platform 10 can not only support the fan 1 itself, but also play a role in shock absorption and sound insulation. By reducing the vibration generated during the operation of the fan 1 from being transmitted to the base 9 and the ground, the noise level can be reduced and the working environment can be improved.

[0022] There is a track 11 on the upper surface of the triangular platform 10. The current collector 12 can move on the track 11, facilitating the maintenance and repair of the interior of the fan 1. The current collector 12, also known as the bell mouth, is the inlet of the fan 1. The interior of the current collector 12 is made of a composite material with a relatively high thermal conductivity. The main components of these composite materials are metal and ceramic, which can improve the heat dissipation effect while maintaining a certain strength. The current collector 12 can evenly introduce gas into the impeller 2 with less loss. The current collector 12 used in this fan 1 is of a cylindrical structure. The main advantage of the cylindrical current collector 12 is that it is simple to process and the loss of air flow entering the impeller 2 is also less. A control device 13 is provided on one side of the current collector 12. In case of a failure, the fan 1 can be stopped by means of the control device 13.
