Description

Technical Field

[0002] A dust removal fan is a device used to remove dust, particulate matter and other harmful substances from the air. Dust removal fans are widely used in industrial production, mines, construction sites and other places. They can effectively purify the air, protect the environment and human health. Their working principle is based on negative pressure. They separate harmful gases and particles such as dust and smoke through attraction and centrifugal force to achieve air purification and dust removal. The types of dust removal fans include centrifugal and axial flow. Centrifugal fans have a higher pressure head and less noise, while axial flow fans are smaller in size and easier to install. When selecting a dust removal fan, factors such as air volume, pressure, noise level, energy consumption, etc. need to be considered, and regular maintenance and cleaning are required to maintain normal operation.

[0003] The problem with the prior art is that a large amount of dust will adhere to the surface of the blades of the dust removal fan after long-term use. The adhesion of this dust will make the surface of the blades rough, resulting in reduced working efficiency. During cleaning, the blades cannot be fully cleaned due to the curvature of the surface, which in turn affects the subsequent use of the dust removal fan. Utility Model Content

[0035] The working principle of this utility model:

[0036] When in use, the shell cover 14 is disassembled, and then the locking rod 19 on the front side of the mounting column 6 is pulled out, and then the L grip rod 1303 inside the fixed cavity 9 is pressed downward. When moving, the L grip rod 1303 squeezes the compression spring 1304 and drives the pushing column 1302 to move downward. When moving, the pushing column 1302 squeezes the inner wall of the inclined hole 1301, thereby driving the inclined block 1204 to move toward the side away from the mounting column 6. When moving, the inclined block 1204 drives the connecting block 1201 to move toward the side away from the mounting column 6. When moving, the connecting block 1201 drives the insertion rod 1202 away from the slot 7 while stretching the two tension springs 1203. At this time, the fan blade 8 can be disassembled and then cleaned.

[0037] In summary: the dust removal fan which is easy to disassemble and clean solves the problem that a large amount of dust will adhere to the surface of the blades of the dust removal fan after long-term use, and the adhesion of such dust will make the surface of the blades become rough, resulting in reduced working efficiency. During cleaning, the surface of the blades has an arc, so that the blades cannot be fully cleaned during cleaning, thereby affecting the subsequent use of the dust removal fan.
