This design helps to improve the suction capacity and overall performance of the fan. The double-suction centrifugal fan is widely used in industrial fields such as cement, lime, nickel-iron, and ceramic sand particle rotary kiln systems.

[0003] An industrial double-suction centrifugal fan with the publication number CN 215058278 U includes a workbench, a fan housing, a maintenance door, and a rotating motor. Pillars are arranged at the four corners of the lower end of the workbench. The fan housing is arranged on one side of the upper end of the workbench. A first protective seat is arranged at the connection between the fan housing and the workbench. Maintenance doors are arranged on the side walls at both ends of the fan housing. An air inlet is arranged in the middle of the outer side wall of the maintenance door. Fastening bolts are arranged at the four corners of the maintenance door. An installation groove is arranged at the connection between the fan housing and the maintenance door. An air outlet is arranged at the upper end of the fan housing. A partition plate is arranged in the middle of the fan housing. A base is arranged on the other side of the upper end of the workbench. An operation panel is arranged on one side of the base. A rotating motor is arranged in the middle of the upper end of the base. A second protective seat is arranged at the connection between the rotating motor and the base. A rotating shaft is arranged at the transmission output end of the rotating motor. A bearing is arranged at the connection between the rotating shaft and the partition plate. Through the design of the rotating shaft, the first support rod, and the second support rod, the double-suction centrifugal fan can have a rotating shaft support function, so that the rotating shaft will not be worn or displaced due to centrifugal force after long-term use, thereby ensuring the working effect of the centrifugal fan.

When the staff finishes cleaning the dust and impurities on the surface of the filter net 16, the resistance generated during air flow is reduced, and the exhaust capacity of the fan is increased. By setting the support frame 2 and the support bottom plate 1 at the bottom of the double-headed motor 3, good support stability can be provided when driving the double-headed motor 3 and the drive assembly 6 inside the first fan housing 5 and the second fan housing 17.
