Embodiment 1

[0028] For large industrial fans, after long-term use, too much dust will be deposited on the surface of the fan blades, which will affect the use of the fan. Please refer to Figure 1-6 , one of which is an industrial large fan with the function of cleaning the dust on the fan blades, including a mounting column 1 and a driving motor 2 under the mounting column 1, the lower end of the driving motor 2 is installed with a revolving frame 7, and the lower end of the revolving frame 7 is provided with a mounting shaft 8. A connecting sleeve 4 is installed on the outer side of the installation shaft 8, a fixing hole 10 is arranged on the lower surface of the installation shaft 8, an insertion pin groove 13 is arranged on the outer side of the connecting sleeve 4, and a flat fan blade is installed inside the insertion pin groove 13. 5. The flat fan blade 5 and the insertion pin slot 13 are fixed by the insertion flat pin 18, the interior of the connecting sleeve 4 is provided with a...

Embodiment 2

[0031] When the sliding sleeve 19 slides for cleaning, it will slide to the top of the flat fan blade 5. When the shaft frame 7 stops rotating, it cannot be reset, and the fan is suspended on the roof, which is extremely difficult and inconvenient for manual operation. This embodiment is in Embodiment 1. Improvements made on the basis of the specific, please refer to Figure 1-6 The interior of the flat fan blade 5 is provided with a limiting groove 6 , and the interior of the flat fan blade 5 is also installed with a shrinking spring 22 located inside the limiting groove 6 , and the shrinking spring 22 is used to connect to one side of the sliding sleeve 19 .

[0032] The sliding sleeve 19 is driven by centrifugal force to slide and clean on the upper surface of the flat fan blade 5, and when the rotation is stopped, the contraction spring 22 will pull it back to its original position for reset processing, which is convenient for multiple cleaning functions.

Embodiment 3

[0034] After the device has been cleaned for a long time, the cleaning structure needs to be replaced to avoid affecting the cleaning efficiency. This embodiment is an improvement made on the basis of Embodiment 2. For details, please refer to Figure 1-6 , the interior of the sliding sleeve 19 is provided with a matching socket 17, and the interior of the sliding sleeve 19 is also installed with a cleaning sleeve 23 located in the matching socket 17.

[0035] Through the clamping structure of the cleaning sleeve 23, the cleaning sleeve 23 can be replaced in a timely manner, so as to avoid cleaning for a long time, resulting in reduced efficiency.

Abstract

The invention relates to the technical field of fans, and discloses an industrial large fan with a fan blade floating dust cleaning function, the industrial large fan comprises a mounting column and a driving motor below the mounting column, a rotating shaft frame is mounted at the lower end of the driving motor, a mounting shaft is arranged at the lower end of the rotating shaft frame, and a connecting sleeve is mounted on the outer side of the mounting shaft; a fixing hole is formed in the lower surface of the mounting shaft, an inserting pin groove is formed in the outer side of the connecting sleeve, a flat fan blade is mounted in the inserting pin groove, and the flat fan blade and the inserting pin groove are fixed through an inserting flat pin. When the mounting shaft drives the flat fan blades to rotate, large centrifugal force can be generated to pull the sliding sleeve towards the outer side, the outer sides of the flat fan blades are swept while pulling is conducted, when rotation stops, the sliding sleeve is pulled back through the contraction spring, sweeping treatment can be conveniently conducted next time, through the structure, the sweeping function of the device can be achieved, and the sweeping efficiency is improved. The structure is simple to operate, and manual interference is not needed.

Description

technical field [0001] The invention relates to the technical field of fans, in particular to an industrial large fan with the function of cleaning the floating dust of the fan blades. Background technique [0002] The large fan is an industrial large fan, which is mainly composed of impeller, casing, motor and other components. Suzhou Puyou Ventilation Co., Ltd. and Shanghai Jiaotong University jointly developed a new generation of high-efficiency, energy-saving and low-noise axial flow fans, and this device is used to clean the dust on the fan blades. [0003] However, in the existing large industrial fans, after a long time of use, too much dust will be deposited on the surface of the fan blades, which will affect the use of the fan, and the fan blades are usually in a blade structure, and the blowing is carried out by rotating and blowing, and the efficiency is low. , and the structure of the connection between the fan blade and the fuselage is relatively thin and easy ...
