Description

Technical Field

[0001] The present application relates to the technical field of fans, and in particular to an energy-saving fan. Background Art

[0002] In the cement production process, the installed capacity of fans accounts for 30% to 35% of the total installed capacity of the cement plant, and the energy consumption accounts for about 30% to 35% of the total consumption of the cement plant. Therefore, fans are the biggest energy consumers in the cement production line.

[0003] In the cement industry, energy-saving fans can save energy by performing frequency conversion and speed regulation on the fans. However, the air inlet duct connected to the energy-saving fan is prone to wear during continuous use, which affects the use of the energy-saving fan. The existing treatment method is to apply adhesive to the air inlet duct and stick magnetic wear-resistant sheets to extend the service life of the air inlet duct. However, this method is not conducive to the replacement of the magnetic wear-resistant sheets. When the magnetic wear-resistant sheets are damaged, they can only be replaced together with the air inlet duct, which will undoubtedly cause waste of the air inlet duct and increase production costs. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide an energy-saving fan, which can solve the technical problem in the prior art that the magnetic wear-resistant sheet pasted in the air inlet duct of the energy-saving fan is difficult to replace.

[0006] Furthermore, a locking assembly is provided at one end of the support frame away from the energy-saving fan body, and the locking assembly includes a locking frame and a locking bolt. The locking frame is fixedly connected to the support frame, and connecting pieces are symmetrically provided on the locking frame. The connecting pieces are provided with threaded holes, and the locking bolt is threadedly connected to the threaded holes. The end of the locking bolt can abut against the outer wall of the air inlet duct.

[0007] Furthermore, the support frame is provided with a plurality of placement grooves, the magnetic wear-resistant sheet is matched with the placement grooves, and the magnetic wear-resistant sheet is placed in the placement grooves.

[0008] Furthermore, one end of the air inlet pipe close to the energy-saving fan body and the air inlet of the energy-saving fan body are both fixedly provided with flanges, and the air inlet pipe and the air inlet of the energy-saving fan body are flange-connected via the flange.

[0009] Furthermore, an annular stopper is fixedly provided on the inner side of one end of the air inlet pipe close to the energy-saving fan body, and one end of the support frame close to the energy-saving fan body abuts against the annular stopper.

[0010] Furthermore, a filter screen is fixedly arranged on the locking frame.

[0011] Beneficial effects of the utility model:

[0012] The utility model arranges a support frame in an air inlet duct connected to the air inlet of the energy-saving fan body, the support frame is detachably connected to the air inlet duct, a plurality of magnetic wear-resistant sheets are provided on the support frame, and the plurality of magnetic wear-resistant sheets are arranged in a cylinder.
