Description

Technical Field

[0001] The present invention relates to the technical field related to explosion-proof motors, and in particular to an explosion-proof motor with a sealed low-noise structure. Background Art

[0002] Explosion-proof motors are motors that can be used in flammable and explosive places and do not generate sparks during operation. Explosion-proof motors are mainly used in coal mines, oil and gas, petrochemical and chemical industries. In addition, they are also widely used in textiles, metallurgy, urban gas, transportation, grain and oil processing, papermaking, medicine and other departments. Explosion-proof motors are the main power equipment and are usually used to drive pumps, fans, compressors and other transmission machinery.

[0003] Flameproof electrical equipment refers to electrical equipment with a flameproof casing, marked with "d". A flameproof casing refers to a casing that can withstand internal explosion forces and prevent the explosion flame from spreading to the surrounding environment. A flameproof motor is a motor with a flameproof casing. The flameproof casing is required to withstand the internal explosion pressure without damage and prevent the explosion flame from spreading outside the casing. Therefore, the flameproof casing should have both explosion-resistant and flameproof properties. The flameproof type is a gap explosion-proof technology that relies on gaps and meshing lengths to achieve the effects of cooling and flameout. When explosion-proof motors are used in daily life, in order to improve the comfort of workers working in the motor operating area, noise reduction treatment will be required through explosion-proof motors.

[0004] The existing Chinese patent application with publication number CN115765278B discloses an explosion-proof motor. The technical problem to be solved is: the content of flammable and explosive gas and dust inside the existing explosion-proof motor is too high, and the motor cannot be effectively cooled down, and there is no emergency measure to deal with the explosion. The technical solution of the invention is: an explosion-proof motor, including a shell and an end cover, etc.; an end cover is fixedly connected to the left and right sides of the shell. The invention realizes cooling the two bearings inside the rotor by the coolant flowing through the inside of the two circulators. Through the circulation pipe that is continuously S-shaped and surrounds the surface of the inner shell, the cooling effect of the coolant inside the rotor and the main shaft is more obvious. Because of the surrounding and continuous S-shape, the contact area between the circulation pipe and the inner shell is greatly increased, and the circulation and heat absorption time is also greatly extended, thereby achieving sufficient cooling of the main shaft, rotor and bearings during the working process.

[0005] The existing Chinese patent application with publication number CN114257017B discloses an explosion-proof motor, comprising: a motor body; a frame assembly, the frame assembly is installed on the outside of the motor body for external protection of the motor body; a heat collecting assembly, the heat collecting assembly is fixedly installed inside the frame assembly for collecting heat from the motor body; a heat conducting device, the heat conducting device is connected to the heat collecting assembly; wherein the heat conducting device comprises: a connecting assembly, the connecting assembly is connected to the heat collecting assembly; a heat dissipating assembly, the heat dissipating assembly is connected to the connecting assembly, and is used to cooperate with the connecting assembly to complete the heat extraction inside the frame assembly. The beneficial effects of the invention are: the device is reasonably designed, and a frame assembly is arranged on the outside to effectively protect the motor body. At the same time, the heat conduction device cooperates with the connecting assembly to realize all-round heat extraction inside the explosion-proof motor, thereby improving the heat dissipation effect and operation stability of the motor body.

[0006] However, this explosion-proof motor has the following defects when used:

[0007] 1. When the existing explosion-proof motor is used in daily life, the explosion-proof motor is directly installed by bolt connection, which has a low shock absorption and buffering effect on the explosion-proof motor. When the explosion-proof motor is used for a long time, it will vibrate up and down, causing friction between the explosion-proof motor and the installation position and generating corresponding noise. At the same time, the vibration release effect of the explosion-proof motor is not good, which easily causes the explosion-proof motor to be in a vibrating operating state for a long time, reducing the service life of the explosion-proof motor;

[0008] 2. When the existing explosion-proof motor is in use, the anti-vibration buffering effect of the explosion-proof motor and the sealing synchronization of the connection of the outer wall interface of the explosion-proof motor are not high, so that when the explosion-proof motor is used daily, the vibration generated for a long time will cause the outer wall interface of the explosion-proof motor to become loose, reduce the sealing effect of the outer wall interface of the explosion-proof motor, and affect the stability of the operation state of the explosion-proof motor.
