Description

Technical Field

[0001] This utility model relates to the field of motor sealing structure technology, specifically a heat dissipation motor sealing structure for a high-pressure explosion-proof fan. Background Technology

[0002] High-pressure explosion-proof fans are widely used in industrial production, and the normal operation of their motors is crucial. However, existing high-pressure explosion-proof fan motor sealing structures have some problems. On the one hand, the motor generates a lot of heat during operation. If this heat cannot be dissipated in time, the motor temperature will rise, affecting its performance and lifespan. On the other hand, existing sealing structures may not effectively prevent external dust, moisture, and other contaminants from entering the motor, thus damaging it. Therefore, a motor sealing structure that can effectively dissipate heat and provide a good seal is needed. Utility Model Content

[0003] The purpose of this utility model is to provide a heat dissipation motor sealing structure for a high-pressure explosion-proof fan, so as to solve the problems mentioned in the background art.

[0004] The technical solution of this utility model is: a heat dissipation motor sealing structure for a high-pressure explosion-proof fan, including an explosion-proof motor body, a matching flange assembly fixed to the end side of the explosion-proof motor body, a heat dissipation assembly provided outside the flange assembly, an annular groove opened on the end side of the explosion-proof motor body near the flange assembly, a sealing element that abuts against the flange assembly is embedded in the annular groove, and multiple sealing rings are provided at the rotatable connection between the end shaft of the explosion-proof motor body and the flange assembly.

[0005] The aforementioned components achieve the following effects: the external heat dissipation components of the flange assembly effectively dissipate the heat generated by the generator; the seal embedded in the annular groove abuts against the flange assembly; and the sealing ring is located at the rotatable connection between the end shaft of the explosion-proof motor body and the flange assembly. This multi-structure combination achieves the dual purpose of heat dissipation and sealing. Compared to traditional motor sealing structures, this design enhances heat dissipation, improves the efficiency of heat dissipation during motor operation, and strengthens the sealing effect, preventing external dust and moisture from entering the motor. This ensures the normal and stable operation of the explosion-proof motor body and extends the motor's service life.

[0006] Preferably, the flange assembly includes a flange fixed to the end side of the explosion-proof motor body, a compression ring adapted to the annular groove is fixed on one side of the flange, the center of the flange is sleeved outside the sealing ring on the end shaft of the explosion-proof motor body, and radial heat dissipation fins are provided on the side of the flange away from the explosion-proof motor body, and the heat dissipation assembly is located outside the heat dissipation fins.

[0007] The aforementioned components achieve the following effects: when the explosion-proof motor is running, heat is conducted to the flange, and the heat dissipation fins increase the heat dissipation area, accelerating heat dissipation to the outside; the compression ring and the seal in the annular groove fit tightly together, enhancing the sealing performance at the motor end. Through the coordinated work of the various parts of the flange assembly, both heat dissipation performance and sealing effect are improved without affecting the motor connection and fixation, ensuring stable operation of the motor in the high-pressure explosion-proof fan and improving the overall reliability of the equipment.

[0008] Preferably, the heat dissipation assembly includes fan blades fixed on the end shaft of the explosion-proof motor body, and the fan blades are covered with a protective cover mesh installed outside the flange.

[0009] The effects achieved by the above components are as follows: when the explosion-proof motor body is running, it drives the fan blades to rotate, which accelerates the air flow. When the air flows through the heat dissipation fins, it quickly carries away the heat, which greatly improves the heat dissipation efficiency compared to relying solely on natural heat dissipation. The protective cover can protect the fan blades and prevent foreign objects from entering and affecting the rotation of the fan blades and the operation of the motor.

[0010] Preferably, the sealing element includes a sealing ring embedded in the annular groove, the sealing ring having an annular extrusion groove on the side near the extrusion ring, and an annular deformation groove on the side of the sealing ring away from the extrusion ring.

[0011] The effects achieved by the above components are as follows: the extrusion groove on one side of the sealing ring deforms under the extrusion ring, closely fitting the extrusion ring and the inner wall of the annular groove, thus enhancing the sealing effect; the deformation groove on the other side provides space for the deformation of the sealing ring, so that the seal can adaptively fill the gap when it is compressed, effectively preventing external dust, moisture and other substances from entering the interior of the explosion-proof motor body.

[0012] Preferably, the outer circumference of the sealing ring is provided with multiple equally spaced annular sealing oil grooves.

[0013] The effects achieved by the above components are as follows: the annular sealing oil groove can store sealing oil. During the operation of the explosion-proof motor body, the sealing oil forms an oil film in the annular sealing oil groove. On the one hand, it further fills the gaps, enhances the sealing performance, and reduces the possibility of external impurities entering the motor. On the other hand, the oil film plays a lubricating role, reducing the friction between the sealing ring and the inner wall of the annular groove and the extrusion ring, reducing the wear of the sealing ring, extending the service life of the seal, and thus ensuring that the motor sealing structure plays a stable role in the long term, improving the overall sealing performance and durability of the motor.

[0014] This utility model provides an improved heat dissipation motor sealing structure for a high-pressure explosion-proof fan, which has the following improvements and advantages compared with the prior art:

[0015] Firstly, this utility model can effectively dissipate the heat generated by the generator through the heat dissipation component outside the flange assembly. The sealing element embedded in the annular groove is pressed against the flange assembly, and the sealing ring is set at the rotatable connection between the end shaft of the explosion-proof motor body and the flange assembly. The combination of multiple structures achieves the dual purpose of heat dissipation and sealing.

[0016] Secondly, this utility model uses the extrusion groove on one side of the sealing ring to deform under the extrusion ring, tightly fitting the extrusion ring and the inner wall of the annular groove, thus enhancing the sealing effect; the deformation groove on the other side provides space for the deformation of the sealing ring, so that the sealing element can adaptively fill the gap when it is compressed, effectively preventing external dust, moisture and other substances from entering the interior of the explosion-proof motor body.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0025] This utility model provides an improved heat dissipation motor sealing structure for a high-pressure explosion-proof fan. The technical solution of this utility model is as follows:

[0026] In embodiments of this utility model, such as Figures 1-4As shown, a heat dissipation motor sealing structure for a high-pressure explosion-proof fan includes an explosion-proof motor body 1. A suitable flange assembly 2 is fixed to one end of the explosion-proof motor body 1. The flange assembly 2 includes a flange 21 fixed to the end of the explosion-proof motor body 1. A compression ring 23 adapted to an annular groove 4 is fixed to one side of the flange 21. The center of the flange 21 is fitted outside the sealing ring 7 on the end shaft of the explosion-proof motor body 1. Radial heat dissipation fins 22 are provided on the side of the flange 21 away from the explosion-proof motor body 1. The heat dissipation assembly is located outside the heat dissipation fins 22. When the explosion-proof motor... When the body 1 is running, heat is conducted to the flange 21. The heat dissipation fins 22 increase the heat dissipation area and accelerate the heat dissipation to the outside. In addition, the extrusion ring 23 and the sealing element 5 in the annular groove 4 are tightly fitted to enhance the sealing performance of the motor end side. A heat dissipation component is provided on the outside of the flange assembly 2. The heat dissipation component includes a fan blade 6 fixed on the end shaft of the explosion-proof motor body 1. The fan blade 6 is covered with a protective cover net 3 installed on the outside of the flange 21. When the explosion-proof motor body 1 is running, it drives the fan blade 6 to rotate, which accelerates the air flow. When the air flows through the heat dissipation fins 22, it quickly carries away the heat.

[0027] An annular groove 4 is provided on the end side of the explosion-proof motor body 1 near the flange assembly 2. A sealing element 5 is embedded in the annular groove 4 and abuts against the flange assembly 2. The sealing element 5 includes a sealing ring 51 embedded in the annular groove 4. An annular extrusion groove 53 is provided on the side of the sealing ring 51 near the extrusion ring 23, and an annular deformation groove 54 is provided on the side of the sealing ring 51 away from the extrusion ring 23. The extrusion groove 53 on one side of the sealing ring 51 deforms under the extrusion of the extrusion ring 23 and fits tightly against the extrusion ring 23 and the inner wall of the annular groove 4 to enhance the sealing effect. The deformation groove 54 on the other side provides space for the deformation of the sealing ring 51, so that the sealing element 5 can adaptively fill the gap when it is compressed, effectively preventing external dust, moisture and other substances from entering the interior of the explosion-proof motor body 1. Multiple annular sealing oil grooves 52 are provided on the outer circumference of the sealing ring 51. The annular sealing oil grooves 52 can store sealing oil. During the operation of the explosion-proof motor body 1, the sealing oil forms an oil film in the annular sealing oil groove 52. On the one hand, it further fills the gaps, and on the other hand, the oil film plays a lubricating role, reducing the friction between the sealing ring 51 and the inner wall of the annular groove 4 and the extrusion ring 23, and reducing the wear of the sealing ring. Multiple sealing rings 7 are provided at the rotatable connection between the end shaft of the explosion-proof motor body 1 and the flange assembly 2.

[0028] The working principle of the heat dissipation motor sealing structure of the high-pressure explosion-proof fan provided by this utility model is as follows: When the explosion-proof motor body 1 is running, heat is conducted to the flange 21, and the heat dissipation fins 22 increase the heat dissipation area. The operation of the explosion-proof motor body 1 drives the fan blades 6 to rotate, accelerating the air flow. When the air flows through the heat dissipation fins 22, it quickly carries away the heat. The extrusion groove 53 on one side of the sealing ring 51 is deformed under the extrusion of the extrusion ring 23, and tightly fits the extrusion ring 23 and the inner wall of the annular groove 4, enhancing the sealing effect. The deformation groove 54 on the other side provides space for the deformation of the sealing ring 51, so that the sealing element 5 can adaptively fill the gap when it is squeezed, effectively preventing external dust, moisture and other substances from entering the interior of the explosion-proof motor body 1.
