Description

Technical Field

[0001] The utility model relates to the technical field of circulating fans, and more specifically, to a heating circulating fan. Background Art

[0002] The high-temperature fan used in the kiln needs to operate stably at high temperatures to circulate the hot air in the furnace and flow evenly for heating. Heating requires a certain pressure and sufficient air volume. With the advancement of science and technology and the intensification of market competition, ordinary kilns can no longer meet the needs of some emerging industries. Focusing on new requirements in the new era, higher requirements are also put forward for fans. Publication No. (CN104314847A) describes a high-speed, high-temperature fan for kiln heating circulation: including a collector, an impeller made of high-temperature resistant materials, a volute and a motor, the impeller is arranged in the volute, the collector is fixed on one side plate of the volute and communicated with the inner cavity of the volute, the drive shaft of the motor is penetrated on the other side plate of the volute, the drive shaft of the motor is installed together with the impeller to drive the impeller to rotate and form a direct-connected transmission, the impeller is installed inside the kiln body, and the motor is installed outside the kiln body. The drive shaft between the impeller and the motor is also successively installed with an insulation block, a heat dissipation impeller and an air guide plate, the insulation block is located inside the kiln body and is arranged close to the furnace wall to form an insulation layer for protecting the heat dissipation impeller and the air guide plate outside the kiln body, and the heat dissipation impeller and the air guide plate cooperate to dissipate the heat of the front end bearing of the motor.

[0003] When the above device is in use, it overcomes the problems of low efficiency and easy breakage of traditional high-temperature fan belt transmission. The size of the fan can be reduced and the cost can be reduced while ensuring production requirements. At the same time, the air flows through the inclined holes on the front cover of the motor and enters the heat dissipation impeller through the air guide plate. The bearing is cooled by the air flow at the air inlet of the air guide plate. However, when the above device circulates the hot air, the heat inside the fan will be directly transferred to the inside of the motor, which can easily affect the working life of the motor.
