Anti-static efficient energy-saving fan

Abstract

The invention relates to the technical field of fans, in particular to an anti-static efficient energy-saving fan. The fan comprises a device body; the device body comprises a supporting frame; and an exhaust bin is fixedly mounted on one side of the supporting frame. By arranging a wetting cylinder, a water storage annular sleeve, a kinetic energy fan, a mounting sleeve and a water distribution rods, a kinetic energy fan is driven to rotate by utilizing air pressure formed after an air inlet fan is started, so that multiple water distribution rods are driven to rotate, and the water distribution rods drive water in a water storage annular sleeve to form a certain amount of water curtain, so that a water curtain can adsorb dust in the air to a certain degree, the density of the dust entering the air inlet fan is reduced, the density of the dust capable of being adsorbed on the fan blades is reduced, and the influence of dust attachment on the air inlet fan is reduced; meanwhile, the water curtain is used for wetting airflow, so that the conductivity of the air is enhanced, and electric charges entering the surface of the fan are brought away when air is in contact with the fan blades.

[0002] With the development of production technology, there is an urgent need to develop medium-flow, medium-high pressure material conveying fans. The conventional national standard is used in material conveying and polishing machine selection (parameters are flow rate 6500-7800m3 / h, total pressure 8000pa, t=20 ℃, atmospheric pressure Pa=101325Pa), change the speed by selecting the national standard fan, for example, 9-19-7.1C power distribution is 30Kw speed 2500rpm, not only the power distribution of the motor is relatively large, but also the C-type belt drive, or type 9 -19-7.1D adopts frequency conversion speed regulation. Compared with the A-type fan drive, the bearing box and other components are added, which leads to a large footprint. The C-type belt drive is not suitable for use in some occasions with anti-static requirements, and the maintenance is relatively relatively. complex drawbacks

[0003] Among them, the PGJ22-2A (power 22Kw, speed 2940rpm) fan can meet the flow rate of 6500-7800m3 / h, the total pressure of 8000pa, t=20℃, the atmospheric pressure Pa=101325Pa, and the total pressure efficiency is over 82%. Compared with the C-type belt drive, the connection between the shafts greatly reduces the generation of external static electricity, but the fan blades are generally coated with more anti-rust paint, which leads to iron or aluminum fans. The leaf becomes an insulator, which makes the fan blade constantly rub against the air during high-speed rotation to generate a certain charge, which in turn increases the probability of subsequent static electricity generation. The charged fan blade is more likely to absorb dust, resulting in the weight and discharge of the fan blade itself. The change of air volume will increase the burden on the output shaft, and the dust removal environment is generally relatively dry, and the generation of static electricity is likely to cause dust explosions in places with high dust content. Therefore, it is necessary to design an anti-static high-efficiency energy-saving fan
