Through the function of the circulating fan, it can be ensured that the aluminum is heated evenly during the heating process, thereby improving production efficiency and product quality. The existing device has swings during long-term operation, which is easy to cause damage to the internal bearings of the fan. Frequent maintenance of the bearings will cause damage to the circulating water-cooled seal of the fan. The maintenance time cost is increased. The motor is independently installed on the top of the heating furnace, which will cause poor heat dissipation. The motor is damaged, which increases the probability of maintenance.

A connecting pipe 21 is mounted below the motor 2 for connection and communication, and an air duct 22 is mounted below the connecting pipe 21 for transmitting airflow. A supporting plate 24 is fixedly arranged in the air duct 22 for fixed support, and a rotating rod 25 is rotatably inserted in the supporting plate 24, and the rotation of the rotating rod 25 drives the impeller 26 to rotate, and an impeller 26 is fixedly arranged on the outer side of the rotating rod 25, and the rotation of the impeller 26 can allow the airflow outside the device to enter the furnace body through the connecting pipe; a mounting plate 11 is fixedly arranged on one side of the inclined plate 1 close to the motor 2 for installation and connection, and the motor 2 is fixed to the mounting plate 11 by screws, and the end of the output shaft of the motor 2 and the rotating rod 25 are connected by a flexible connection, and the impeller 26 is located on the inner side of the air duct 22, and the flexible connection is usually used to connect two shafts or a shaft and a transmission device, and can absorb vibration, reduce impact and torque transmission error to a certain extent, thereby protecting other components of the transmission system.

[0018] An air outlet 3 is provided on the outside of the air duct 22 , and a bellows 31 is fixedly installed on the air outlet 3 . A filter plate 32 is movably inserted in the bellows 31 , and a handle 33 is fixedly provided on the top of the filter plate 32 .

[0019] By adopting the above technical solution, the impeller 26 rotates to drive the external airflow into the bellows 31 through the air guide box 34. When the airflow enters the bellows 31, it first passes through the filter plate 32. The filter plate 32 can filter the suspended matter in the airflow to prevent the equipment from running for a long time, causing a large amount of particles to enter the furnace body, resulting in a large number of attachments and impurities in the furnace body, which will further affect the normal operation of the furnace body, thereby achieving the purpose of filtering the airflow.

[0020] The bottom end of the motor 2 is fixedly connected to the top end of the connecting pipe 21 through a flange and bolts.

[0021] By adopting the above technical solution, it is convenient to install and disassemble the connecting pipe 21 and the motor 2.

[0022] The bottom end of the connecting pipe 21 and the top end of the air duct 22 are fixedly connected by a flange and bolts.

[0023] By adopting the above technical solution, the connecting pipe 21 and the air duct 22 can be conveniently connected, installed and disassembled through the flange.

[0024] A fixing plate 12 is fixedly provided at the bottom end of the inclined plate 1 , and screw holes distributed in a rectangular array are provided in the fixing plate 12 .

[0025] By adopting the above technical solution, the fixing plate 12 and the screw holes facilitate the connection of the motor 2 and the tilting plate 1 to the outside, thereby playing a role in installation, and further playing a role in supporting the motor 2 and the fan.

[0026] A mounting groove 23 is formed on the outer side of the connecting pipe 21 .

[0027] By adopting the above technical solution, the installation groove 23 facilitates the connection and installation operations of the motor 2 and the rotating rod 25, thereby achieving the purpose of convenient operation and installation.

[0028] A connecting flange 27 is fixedly mounted on the bottom end of the air duct 22 .

[0030] An air guide box 34 is fixedly provided at one end of the air box 31 away from the air duct 22 .

[0031] By adopting the above technical solution, the air guide box 34 can expand its opening, so that the air flow can enter the wind box 31 more efficiently, thereby expanding the air intake area and increasing the air intake volume.

[0032] Working principle: During operation, first start the motor 2 to make the motor 2 start working. The end of the output shaft of the motor 2 rotates through the soft connector to drive the rotating rod 25 to rotate, so that there is no need to worry about vibration during long-term operation. The rotation of the rotating rod 25 drives the impeller 26 to rotate. The rotation of the impeller 26 drives the external airflow into the wind box 31 through the air guide box 34. When the airflow enters the wind box 31, it first passes through the filter plate 32. The filter plate 32 can filter the suspended matter in the airflow to avoid the long-term operation of the equipment, causing a large amount of particles to enter the furnace body, resulting in attachments in the furnace body. There are many impurities, which will affect the normal operation of the furnace body, thereby achieving the purpose of filtering the airflow, and the filtered airflow will enter the air duct 22 through the bellows 31 and the air port 3, and then enter the furnace body through the air duct 22. The motor 2 and the fan are installed vertically, and are driven by a transmission shaft and a flexible connection in the middle. It is not easy to cause bearing damage, it is not easy to cause circulating water cooling seal damage, and it can reduce the frequency of maintenance and protect the circulating water cooling insulation layer. By increasing the vertical height of the motor 2, the heat dissipation is better, and the motor 2 is not easy to be damaged, thereby reducing the probability of problems and making the equipment run more stable.

[0033] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
