Technical Field

[0001] The present application relates to the field of centrifugal fans, and particularly to a centrifugal fan with a dust extraction function. Background Art

[0002] A centrifugal fan is a ventilation machine that works based on the principle of centrifugal force. It generates an air flow through the rotation of an impeller, sucking in gas axially and discharging it radially. Centrifugal fans are widely used in the fields of ventilation, dust removal, and material transportation in industrial production, and are favored for their high efficiency, high pressure, and low noise.

[0003] Existing centrifugal fans with a dust extraction function usually use a filter screen to filter and separate dust in the air flow. However, the filter screen will become clogged after filtering for a period of time and needs to be regularly disassembled for cleaning or replacement, which is not convenient for use.

The exhaust component includes a wind guiding housing, and the wind guiding housing is fixedly installed outside the separation housing, and on one side at the bottom of the wind guiding housing, there is an exhaust interface.

[0007] By adopting the above scheme, a centrifugal component is provided inside the separation component, and an exhaust component is provided outside the separation component, which facilitates the centrifugal component to generate air flow during operation. The air flow passes through the separation component to separate and extract dust, and the air flow after dust extraction is discharged from the exhaust component. A fixing frame is fixedly installed inside the installation hole, and a filter screen is rotatably connected inside the fixing frame, which facilitates the fixed installation of the filter screen on the separation shell, and is convenient for the air flow generated during the operation of the centrifugal component to pass through the filter screen to filter and separate the dust in the air flow. A gear is fixedly installed at one end of the filter screen, and the gear is arranged outside the separation shell, which facilitates the rotation of the filter screen outside the separation shell, so that the side of the filter screen blocked by dust is away from the centrifugal impeller, and is convenient for the air flow generated by the rotation of the centrifugal impeller to perform backwashing on the filter screen, blowing off the blocked dust, thereby restoring the filtering ability of the filter screen and avoiding the trouble of disassembling the filter screen for cleaning and replacement. An exhaust interface is provided on one side of the bottom of the air guide shell, which is convenient for connecting an external exhaust pipe and facilitating the air flow extracted from the separation component to be discharged from the exhaust interface. When the filter screen is backwashed and restored, the air flow with dust blocking the filter screen is also discharged from the exhaust interface, which is convenient for collection and treatment.

[0008] Further, a rotating ring is rotatably connected to one side of the separation shell, and two rotating handles are fixedly installed on one side of the rotating ring.

[0018] Further, the other end of the coupling is provided with a centrifugal impeller, the centrifugal impeller is arranged inside the separation shell, and the output end of the coupling is fixedly connected to the centrifugal impeller.

[0019] By adopting the above solution, since the centrifugal impeller is arranged inside the separation shell and the output end of the coupling is fixedly connected to the centrifugal impeller, it is convenient for the driving motor to drive the centrifugal impeller to rotate, thereby generating an air flow.

[0020] Further, a collector is fixedly installed on the side of the separation shell away from the driving motor, and one end of the collector is inserted inside the centrifugal impeller.

[0021] By adopting the above solution, since a collector is fixedly installed on the side of the separation shell away from the driving motor and one end of the collector is inserted inside the centrifugal impeller, it is convenient to guide the gas entering the device and improve the exhaust efficiency of the device.

[0022] In summary, the present application has the following technical effects:

The air flow passes through the separation component to separate and extract dust, and the air flow after dust extraction is discharged from the exhaust component. By fixedly installing a fixing frame inside the installation hole and rotatably connecting a filter screen inside the fixing frame, it is convenient to fixedly install the filter screen on the separation shell, facilitating the air flow generated when the centrifugal component works to pass through the filter screen and filter and separate the dust in the air flow. By fixedly installing a gear at one end of the filter screen and arranging the gear outside the separation shell, it is convenient to rotate the filter screen outside the separation shell to make the side of the filter screen blocked by dust away from the centrifugal impeller, facilitating the air flow generated by the rotation of the centrifugal impeller to backflush the filter screen and blow off the blocked dust, thereby restoring the filtering ability of the filter screen and avoiding the trouble of disassembling the filter screen for cleaning and replacement. By opening an exhaust interface on one side of the bottom of the air guide shell, it is convenient to connect an external exhaust pipe, facilitating the air flow extracted from the separation component to be discharged from the exhaust interface. When backflushing and restoring the filter screen, the air flow with dust blocking the filter screen is also discharged from the exhaust interface, facilitating collection and treatment, achieving the effect of filtering and dust extraction for the air flow, and not requiring regular disassembly of the filter screen for cleaning and replacement, having high practical value.
