All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-7, a novel high temperature resistant industrial fan comprises a main body 1, a fan channel 2 is formed in the main body 1, a roots fan 3 is rotatably connected in the fan channel 2, a coil 4 is fixedly connected in the fan channel 2, a main rod 5 is rotatably connected in the fan channel 2, a limit rod 6 is fixedly connected to the outer ring of the main rod 5, a limit spring 7 is fixedly connected in the limit rod 6, an impeller 8 is fixedly connected to the outer ring of the main rod 5, a fixed magnet 9 is movably connected to the side surface of the impeller 8, an inertial spring 10 is fixedly connected to the bottom end of the fixed magnet 9, a chucking spring 11 is fixedly connected in the top end of the fixed magnet 9, a chucking block 12 is fixedly connected to the top end of the chucking spring 11, a chucking rod 13 is fixedly connected to the side surface of the fixed magnet 9, a chuck 14 is rotatably connected to the side surface, the inner ring of the fan channel 2 is rotatably connected with a clamping shaft 16, and the outer ring of the clamping shaft 16 is fixedly connected with a shifting lever 17.

Wherein: the inner wall of the fan channel 2 is provided with a groove matched with the limiting rod 6, the top ends of two sides of the limiting rod 6 are rotatably connected with idler wheels, and the idler wheels are movably clamped with the idler wheels of the limiting rod 6 through the groove.

Wherein: the fixed magnet 9 is movably connected with the straight groove arranged in the limiting disc fixedly connected with the side surface of the impeller 8.

Wherein: the inside swivelling joint of card axle 16 has the ball valve, and the inside of driving lever 17 has seted up the cooling tube, and the cooling mouth of pipe is just closed to the ball valve under the natural state.

Wherein: the coil 4 is supplied with a fixed input current by an external motor.

Wherein: six clamping grooves 15, six clamping rods 13, six clamping shafts 16, six shift rods 17 and six fixed magnets 9 are respectively arranged, the six clamping grooves are uniformly distributed by taking the central axis of the fan channel 2 as the center of a circle, and the clamping blocks 12 are matched with the clamping shafts 16.

Wherein: the slot 15 is formed in two parts, and the two opened parts are connected at the topmost end.

The working principle is as follows: the main body 1 of the device is powered by the Roots blower 3, and the gas to be conducted is conducted to the lower end from the upper end of the main body 1 under the action of the two rotary blowers, so that the aim of exhausting and cooling is fulfilled.

In the running process of the equipment, because the inner ring of the fan channel 2 is fixedly connected with the coil 4 in the on state, the coil 4 can provide a certain repulsive force for the fixed magnet 9 connected with the surface of the main rod 5, and all structures directly connected with the main rod 5 keep suspension relative to the fan channel 2 through the main rod 5, in the rotating process of the impeller 8, the zero friction effect is realized in a non-contact mode, and the temperature of the fan structure in the running process is further reduced to achieve the purpose of high temperature resistance, wherein the limiting rod 6 is used for determining the position of the limiting rod relative to the coil 4, and the limiting spring 7 can buffer the relative displacement of the structures in the vibration process of the structure.

The larger the rotating speed of the fan is, the higher the instability of the fan is, the higher the probability of structural damage when the structure conflicts is, but if the input current of the coil 4 is fixedly arranged, the current which is not required to be so large when the rotating speed of the impeller 8 is small can cause energy waste to a certain extent, the main rod 5 can synchronously drive the fixed magnets 9 to rotate in the rotating process, due to inertia, the fixed magnets 9 can be mutually diffused, the inertia spring 10 is stretched, the magnetic flux between the fixed magnets 9 and the coil 4 can be increased, the rotating speed is in direct proportion to the size of the magnetic flux, the current in the coil 4 can be enhanced by cutting magnetic induction lines in the rotating process, and the suspension clamping force on the main rod 5 can be further increased. Wherein, the fixed magnet 9 realizes relative synchronous motion through a clamping groove 15 arranged on the surface of the chuck 14.

In the rotating process of the impeller 8, the shifting rod 17 is also mutually diffused due to inertia, a ball valve inside the clamping shaft 16 in rotary connection is opened, the rotating speed is larger, the relative rotation of the clamping shaft 16 is larger, the valve opening is larger, the cooling liquid flows out through a cooling pipe inside the shifting rod 17 at the moment, heat is evaporated and taken away, the rotating speed is larger, the outflow cooling liquid is more, proper adjustment can ensure that the cooling liquid can be completely evaporated just, and no liquid is generated during output.

When the fan is overloaded, the rotation speed of the impeller 8 reaches the upper limit, the fixed magnet 9 moves to the limit position, the top end drives the clamping rod 13 to be separated from the top end position of the clamping groove 15 and drive the chuck 14 to rotate reversely, the clamping block 12 just clamps the clamping shaft 16 reversely, the shifting lever 17 rotates reversely, and the ball valve is closed, so that the purposes of locking and avoiding the outflow of the internal non-evaporated cooling liquid are achieved.
