Explosion-proof motor with efficient heat dissipation function

Abstract

The invention discloses a flame-proof motor with an efficient heat dissipation function, the flame-proof motor comprises a motor main body, a main shaft and a sealing device, a wire connector is arranged above the motor main body, a fixing device is arranged below the motor main body, a cooling device is arranged on one side of the motor main body, and the sealing device is arranged on the other side of the motor main body. The cooling device is composed of the cooling cover and the cooler, gas in the motor shell can be sucked into the cooler through the main shaft, the transmission shaft and the gear pump, cooling water in the cooling pipe circularly flows into the heat exchange pipe, and then the cooling purpose is achieved. According to the explosion-proof motor, energy generated by vibration of the explosion-proof motor can be converted into kinetic energy of the first fan blades through the conversion mechanism, a group of protective layers can be formed on the outer surface of the motor shell through the first fan blades and the ventilation pipe, and flammable and explosive gas or dust is prevented from entering the interior of the explosion-proof motor to cause secondary explosion when the explosion-proof motor is shut down due to explosion.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a flameproof motor with efficient heat dissipation. Background technique [0002] Explosion-proof motors are also called explosion-proof motors. Compared with ordinary motors, they have a flameproof casing. The casing is usually extremely thick. The explosion gap ignites the explosive mixture around the motor housing. [0003] In order to ensure the explosion-proof effect, the current explosion-proof motor is usually equipped with a sealing device to separate the internal environment of the explosion-proof motor from the external environment, preventing the outside flammable and explosive gas or dust from entering the explosion-proof motor, thereby causing explosion-proof damage. The motor explodes, but the internal temperature of the flameproof motor will rise rapidly when it works for a long time. The heat dissipation effect of the heat sink on the flameproof motor shell alone ...

[0003] In order to ensure the explosion-proof effect, the current explosion-proof motor is usually equipped with a sealing device to separate the internal environment of the explosion-proof motor from the external environment, preventing the outside flammable and explosive gas or dust from entering the explosion-proof motor, thereby causing explosion-proof damage. The motor explodes, but the internal temperature of the flameproof motor will rise rapidly when it works for a long time. The heat dissipation effect of the heat sink on the flameproof motor shell alone is not good. With the use of flameproof motors, the sealing performance of flameproof motors will gradually decrease, so that flammable and explosive gases or dust from the outside will slowly enter the flameproof motors. The existing flameproof motors usually cannot judge the flameproof motors. Whether there is flammable and explosive gas or dust inside, which makes it inconvenient for the staff to shut down for maintenance. Finally, when an explosion occurs inside the flameproof motor and stops working, the temperature inside the flameproof motor will not drop immediately, and even the inside of the flameproof motor will There will also be sparks. If the quality of the explosion-proof motor casing is not good enough and cracks appear, once the outside flammable and explosive gas or dust enters the flame-proof motor, it is very easy to cause a secondary explosion.
