Abstract
Description
Technical Field
[0001] This utility model relates to the field of fan technology, specifically a high-temperature and high-pressure resistant fan motor. Background Technology
[0002] The air inlet and outlet of the high-temperature and high-pressure resistant fan are connected to the equipment pipeline to enable the medium to be transported in a high-temperature and high-pressure working environment. Many industries have harsh working environments, and the fan motor needs to withstand high temperature and high pressure. Currently, circulating fans on the market cannot withstand high-temperature and high-pressure working environments, which leads to leakage of high-temperature and high-pressure media or burnout of the motor, and the equipment cannot work normally. Utility Model Content
[0003] To address the aforementioned problems, the purpose of this invention is to provide a high-temperature and high-pressure resistant fan motor that can withstand high-temperature and high-pressure working environments.
[0004] To achieve the above objectives, the technical solution of this utility model is as follows: a high-temperature and high-pressure resistant fan motor, comprising a fan body and a motor body, wherein a freely rotatable high-pressure impeller is provided inside the fan body, an air intake flange communicating with the inside of the fan body is provided on the outside of the high-pressure impeller, an air outlet flange communicating with the inside of the fan body is provided on the top of the fan body, a connecting flange is fixedly connected to the fan body opposite to the air intake flange, the other end of the connecting flange is fixedly connected to the outer shell of the motor body, a rotor with a motor shaft is provided inside the motor body, the motor shaft extends into the fan body and drives the high-pressure impeller to rotate, and an annular hollow water-cooling cavity is provided on the outer shell of the motor body, and an inlet and an outlet communicating with the inside of the hollow water-cooling cavity are respectively provided on the outer shell of the motor body.
[0005] Furthermore, the other end of the motor body casing is covered with a sealed end cap.
[0006] Furthermore, sealed bearings and sealing rings are fitted onto the portion of the motor shaft that passes through the motor body housing.
[0007] Furthermore, the sealing end cap consists of two cylindrical structures that cover the end cap respectively.
[0008] Furthermore, the outlet flange is tangent to the cylindrical outer wall of the fan body.
[0009] Furthermore, the air intake flange and the air outlet flange are fixedly connected to the corresponding pipes through flange structures.
[0010] Furthermore, the inner diameter of the air intake flange is larger than the inner diameter of the air outlet flange.
[0011] The high-pressure impeller inside the fan body of this utility model is driven by the motor body. The high-pressure impeller transports the high-temperature and high-pressure medium from the air inlet flange to the air outlet flange, thus forming a closed loop of the high-temperature and high-pressure medium. The outer shell of the motor body is respectively provided with water inlet and water outlet that are connected to the hollow water-cooling cavity. Through the water inlet and water outlet, it is connected to the external water-cooling system, continuously introducing cold water and discharging the water after heat exchange, forming water-cooling to prevent the motor body from overheating. This makes the motor body resistant to high temperature and high pressure, and leak-proof, allowing the fan body to withstand the high-temperature and high-pressure working environment, effectively preventing leakage of high-temperature and high-pressure medium or motor burnout, and ensuring normal operation of the equipment. Attached Figure Description
[0012] The present invention will now be further described with reference to the accompanying drawings.
[0013] Figure 1 This is a schematic diagram of the main structure of this utility model; Figure 2 for Figure 1 A schematic diagram of the AA section structure. Detailed Implementation
[0014] like Figure 1-2 As shown, a high-temperature and high-pressure fan motor includes a fan body 2 and a motor body 4. A freely rotatable high-pressure impeller 6 is installed inside the fan body 2. An air intake flange 1 communicating with the inside of the fan body 2 is installed on the outside of the high-pressure impeller 6. An air outlet flange 5 communicating with the inside of the fan body 2 is installed on the top of the fan body 2. A connecting flange 3 is fixedly connected to the fan body 2 opposite to the air intake flange 1. The other end of the connecting flange 3 is fixedly connected to the outer shell of the motor body 4. A rotor with a motor shaft 7 is installed inside the motor body 4. The motor shaft 7 extends into the fan body 2 and drives the high-pressure impeller 6 to rotate. An annular hollow water-cooled cavity 8 is installed on the outer shell of the motor body 4. An inlet 9 and an outlet 10 communicating with the inside of the hollow water-cooled cavity 8 are respectively provided on the outer shell of the motor body 4.
[0015] In addition, the other end of the motor body 4 housing is covered with a sealing end cover 11, which is composed of two cylindrical structures covering the end cover respectively. The part of the motor shaft 7 that passes through the motor body 4 housing is fitted with a sealing bearing 12 and a sealing ring respectively.
[0016] Specifically: the air outlet flange 5 is tangent to the cylindrical outer wall of the fan body 2, the air intake flange 1 and the air outlet flange 5 are fixedly connected to the corresponding pipes through the flange structure, and the inner diameter of the air intake flange 1 is larger than the inner diameter of the air outlet flange 5.
[0017] The working principle of this utility model is as follows: The high-pressure impeller 6 inside the fan body 2 is driven by the motor body 4. The high-pressure impeller 6 transports the high-temperature and high-pressure medium from the suction port flange 1 to the outlet flange 5, thereby forming a closed loop of the high-temperature and high-pressure medium. The outer shell of the motor body 4 is respectively provided with a water inlet 9 and a water outlet 10 that are connected to the interior of the hollow water-cooled cavity 8. Through the water inlet 9 and the water outlet 10, it is connected to the external water-cooling system, continuously introducing cold water and discharging the water after heat exchange, thus forming water-cooled cooling. This prevents the motor body 4 from overheating, thereby making the motor body 4 resistant to high temperature and high pressure and leak-proof. This avoids the leakage of high-temperature and high-pressure medium or motor burnout due to the fan body 2 being unable to withstand the high-temperature and high-pressure working environment, which would prevent the equipment from working normally.
[0018] The above description is merely an illustrative embodiment of this utility model and is not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model.
