Description

Technical Field

[0001] This utility model relates to the field of motor technology, specifically to a motor cooling device. Background Technology

[0002] The motor of a rotary kiln is mainly used to drive the rotation of the rotary kiln. It usually uses AC motors and DC motors. With the development of technology, AC motors have gradually replaced DC motors because AC motors have advantages in terms of performance and maintenance. In the current technology, the rotary kiln motors in old factories generate heat due to long-term operation, which needs to be dissipated and cooled in time to avoid overheating and damage. However, the rotary kiln motors in the factory are cooled by heat sinks on the outer shell. However, in summer, the old rotary kiln motors cannot dissipate heat in time by heat sinks alone, resulting in overheating and damage to the rotary kiln motors. Therefore, a motor cooling device is proposed. Utility Model Content

[0003] This utility model proposes a motor cooling device, which solves the problem in related technologies where rotary kiln motors in old factories generate heat due to long-term operation and need to be cooled in time to avoid overheating and damage. However, the heat dissipation of rotary kiln motors in factories is achieved through heat sinks on the outer shell. However, in summer, the heat sinks alone cannot dissipate heat in time, leading to overheating and damage to the rotary kiln motor.

[0004] The technical solution of this utility model is as follows: a motor cooling device, comprising: a motor and heat sinks having a motor surface; The outer surface of the motor is provided with multiple sets of connecting components. The surface of the connecting components is provided with a mounting ring. The surface of the mounting ring is provided with multiple air inlets. The inner wall of the air inlet is fixedly connected with an arc-shaped shell. One side of the arc-shaped shell is provided with multiple mounting ports. The inner wall of each of the multiple mounting ports is fixedly connected with an axial flow fan. A flow guide shroud is fixedly connected to one side of the mounting ring, and a flow guide shell is provided on one side of the flow guide shroud.

[0005] Optionally, the connecting component includes two fixing blocks disposed on the outer surface of the motor, a fixing post disposed inside the fixing blocks, and multiple bolts. Both ends of the surface of the fixed column are provided with external threads for the mating bolts, and one end of the surface of the fixed column is threadedly connected to a bolt for the mating mounting ring.

[0006] Optionally, the two fixing blocks are respectively located at both ends of the motor, and the surface of the fixing block is provided with a circular opening for cooperating with the fixing post. The mounting ring is installed on the surface of the fixing post.

[0007] Optionally, the outer surface of the motor is provided with a plurality of support columns that cooperate with the flow guide shell, and one end of the support column is connected to one side of the flow guide shell.

[0008] Optionally, the surfaces of the flow guide and the flow guide shell are coated with a protective paint.

[0009] Optionally, a cooling port is provided on the surface of the arc-shaped shell, and a refrigeration shell is fixedly connected to the inner wall of the cooling port.

[0011] Optionally, the heating surface of the semiconductor cooler is provided with heat dissipation fins, and the outer surface of the cooling shell is provided with multiple air inlets, the inner wall of the air inlets being provided with a dust filter.

[0012] The working principle and beneficial effects of this utility model are as follows: I. The structure of this application is reasonable. An axial flow fan allows external gas to enter the arc-shaped shell. Then, the gas comes into contact with the heat sink on the surface of the motor through the guide shroud. At the same time, the guide shroud blows the gas from the head to the tail of the motor, so that the gas comes into contact with the heat sink of the motor shell, achieving the best cooling effect for the motor.

[0013] Second, the structure of this application is reasonable. The temperature inside the arc-shaped shell is detected by a temperature sensor. When the temperature inside the arc-shaped shell reaches the preset temperature, the temperature inside the arc-shaped shell is reduced by the cooling surface of the semiconductor cooler, so as to reduce the temperature of the gas blown onto the heat sink and better cool the motor.

[0014] Third, this application is reasonable. When adding a heat dissipation device to the rotary kiln motor in an old factory area, the fixing block is fixed to the motor surface by electric welding. The fixing column passes through the round opening on the surface of the fixing block, and then the fixing column is fixed to the surface of the fixing block by bolts with two threads. Finally, the mounting ring is installed at one end of the fixing column. When the mounting ring is installed in the predetermined position, the mounting ring is fixed by bolts. In summary, by adding a cooling device to the old motor, the service life of the motor is extended. Attached Figure Description
