Automatic dust removal device for preventing indoor ventilation from being influenced by excessive dust in fan

Abstract

The invention relates to the technical field of industrial fans, and discloses an automatic dust removal device for preventing indoor ventilation from being influenced by excessive dust in a fan. Theautomatic dust removal device comprises a shell, the top in the shell is fixedly connected with a drive motor, the left side of the drive motor is fixedly connected with a driving disc, and the top ofthe driving disc is in transmission connection with a transmission belt. According to the automatic dust removal device for preventing indoor ventilation from being influenced by excessive dust in the fan, the drive motor is started, a screw periodically rotates forwards and reversely at the moment, furthermore a brush periodically sweeps a filter screen up and down, at the moment, falling dust can be blown out of the fan by wind generated by rotation of fan blades, and therefore the effect of automatically removing dust in the fan is achieved. A sliding block is pushed left and right, a fixed plate drives a transmission ball to move left and right at the moment, the transmission ratio between a driven cone and a driving cone is further changed, the rotating speed of the fan blades can also be changed at the moment, and therefore the effect of adjusting the wind speed according to field requirements is achieved.

Description

technical field [0001] The invention relates to the technical field of industrial fans, in particular to an automatic dust removal device for preventing indoor ventilation from being affected by too much dust inside the fan. Background technique [0002] Industrial fans refer to fans that are specially used for ventilation in tunnels, underground garages, high-grade civil buildings, metallurgy, factories and mines, and high-temperature smoke exhaust for fire fighting. It is mainly composed of impeller, casing, inlet collector, heat conduction fin, motor and other components. [0003] During the long-term use of the fan, the filter inside the fan will be covered with dust, which not only affects the ventilation inside the fan, but also affects the heat dissipation inside the fan. Manual cleaning is required. The cleaning process is cumbersome, and the structure and function of the existing fan It is relatively simple, there are only two gears of high wind speed and low wind ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an automatic dust removal device that avoids too much dust inside the fan from affecting indoor ventilation. During long-term use, the filter inside the fan will be covered with dust, which not only affects the ventilation inside the fan, but also affects the heat dissipation inside the fan. Manual cleaning is required. The cleaning process is cumbersome, and the structure and function of the existing fan are relatively Single, there are only two gears of high wind speed and low wind speed, the problem that the wind speed cannot be adjusted according to the needs of the site
