    A TYPE OF EXPLOSION-PROOF MOTOR
    Technical area
    The new invention relates to the motor, especially a type of explosion-proof motor.
    State of the art
    With the development of electric automation, industrial manufacturing requires the use of more and more motors. In every industry, manufacturing is steadily increasing, so the engine is often in an overload condition and overheating the engine will accelerate the aging of the production lines, increasing the risk of engine explosion to a certain extent. state. In some special industries, such as the mining industry, the environment in which the engine operates often contains many explosive mixtures. In this case, the consequences of the engine explosion are very serious. Many engines on the market add a protective layer to prevent the explosion of the engine, but this can only solve a small part of the problem, since this means only reduces the surrounding damage caused by the explosion of the engine. How to reduce the destructive power of the explosion and how to prevent the explosion of the engine and reduce the probability of the explosion The solution of the two problems at the same time is a challenge which the industrialist must face.
    Statement of the invention
    The object of the invention is to provide a type of explosion-proof motor which has significant advantages, in particular time cooling, explosion-proof ability and high safety performance.
    To achieve these objectives above, a new type of explosion-proof motor is produced, comprising a motor body, an explosion-proof housing, an end cover and a circulation fan. The motor body is in the explosion-proof housing; the end cover is arranged at the end of the explosion-proof housing; the circulation fan is placed at the end of the axis of the motor body. An explosion-proof partition is installed on the wall
    BE2018 / 5268 inside the explosion-proof enclosure. On the outer wall of the flameproof enclosure there is a cooling jacket and there are a number of air ducts in the direction of extension of the cooling jacket to the flameproof motor. One end of the air duct is connected to the cover, the other end is connected to the inside of the flameproof enclosure.
    In addition, an air deflector is disposed on the connection between the end cover and the flameproof enclosure, and a number of ventilation holes are distributed over the air deflector.
    In addition, the side of the air deflector facing the flameproof enclosure is arcuate.
    The explosion-proof motor also contains a temperature sensor, a temperature controller and an electromagnetic control valve installed at the inlet of the cooling jacket. The temperature sensor is on the inside wall of the flameproof enclosure. The temperature sensor generates a signal which is transmitted to the temperature controller and the temperature controller is in electrical connection with the electromagnetic control valve.
    Compared with the prior art, the invention has positive effects, such as such as rapid cooling, explosion-proof ability and high safety performance.
    Description of the drawings
    Other characteristics, object and advantages of the invention will appear on reading the description and the drawings below, given only by way of nonlimiting examples. In the accompanying drawings:
    Figure 1 is an embodiment of an explosion-proof motor according to the present invention.
    FIG. 2 is the diagram of the structure of the air ducts in an example of application of the invention.
    Description of a preferred embodiment
    BE2018 / 5268
    FIGS. 1 and 2 illustrate an embodiment of the invention, consisting of a type of explosion-proof motor, which comprises: a body of the motor 1, an explosion-proof housing 2, an end cover 3 and a circulation fan 4. The body of the motor 1 is in the explosion-proof housing 2; the end cover 3 is arranged at the end of the explosion-proof housing 2. On the connection of the end cover 3 and the explosion-proof box 2, there is a sealing ring 13 to improve the overall seal and prevent the flammable and explosive external gas from entering the body of the engine 1 and causing a explosion.
    The circulation fan 4 is placed at the end of the axis of the motor body 1. The explosion-proof partition 5 is installed on the inner wall of the explosion-proof housing 2. There is a cooling jacket 6 on the outer wall of the explosion-proof box 2. In the direction of extension of the cooling jacket 6 towards the explosion-proof motor, there are also a certain number of air ducts 7 and one end of the air duct 7 connected inside. of the end cover 3. The other end is connected to the inside of the explosion-proof housing 2. An air deflector 8 is arranged on the connection between the end cover 3 and the explosion-proof housing 2, and a certain number of holes 9 are distributed over the air deflector 8. In order to reduce the noise generated when starting the circulation fan 4, the side of the air deflector 8 facing the explosion-proof housing 2 is in the shape of an arc, in. to ensure dispersion of the air flow.
    When the engine is running, the coolant circulates continuously from the inlet to the outlet of the cooling jacket 6 to dissipate the heat generated by the operation of the engine body 1. At the same time, the circulation fan 4 generates a flow of air circulating between the body of the engine 1 and the air ducts 7. The gas transporting heat makes the heat exchange with the liquid in the cooling jacket 6 by the air ducts 7. This improves the cooling efficiency and thus effectively prevents overheating of the motor body 1.
    In this illustrative example, the new type of explosion-proof motor also contains a temperature sensor 10, a temperature regulator 11 and an electromagnetic control valve 12 installed at the inlet of the cooling jacket 6. The temperature sensor 10 is on the interior wall of the explosion-proof enclosure 2. The temperature sensor 10 is electrically connected to the temperature controller and the temperature controller 11 is electrically connected to the electromagnetic control valve 12. The body temperature of the motor 1 is monitored in real time by the temperature sensor 10 and
    BE2018 / 5268 the collected temperature signal is transmitted to the temperature controller 11. The temperature controller 11 compares the temperature signal with a predefined temperature value. If the temperature signal exceeds the predefined temperature, the temperature controller 11 sends an increase instruction to the electromagnetic control valve 12 to increase the flow of coolant and improve the cooling rate; on the contrary, the temperature regulator 11 sends a lowering instruction to the electromagnetic regulation valve 12 to lower the flow rate of the coolant and slow down the cooling rate. Real-time monitoring can save energy and reduce emissions.
    Moreover, the end cover 3 is provided with an air inlet 14 and an air outlet 15 allowing the entry and exit of the inert gas. Before the engine body 1 operates, the interior of the flameproof enclosure 2 can be ventilated several times by the air inlet 14 and the air outlet 15 so that the engine body 1 is completely in an atmosphere. inert gas. This would avoid electro-optical detonation and other problems.
    In short, the explosion-proof motor provided in this application example has advantages, such as time cooling, explosion-proof ability and high safety performance.
