Electromagnetic shaftless vortex blade centripetal type high-pressure fan

Abstract

The method belongs to the technical field of high-strength, low-noise and centripetal type high-pressure fans, and discloses an electromagnetic shaftless vortex blade centripetal type high-pressure fan. The high-pressure fan is characterized by being provided with shaftless continuous forward centripetal vortex blades, and the outer edges of the radii, centripetal angles, bending, blade channel space and thread pitches of the centripetal vortex blades in a continuous long strip-shaped vortex blade channel are changed in order from large to small; a stator and a rotor are arranged in the electromagnetic field of a motor, and a high-pressure fan is arranged in the center of the rotor for synchronous rotation; and in the shaftless centripetal type shaftless continuous forward centripetal vortex blades, air particles are in contact with the blades for a long time in blade channels to exchange energy, and pressure and rotating force with the ultrastrong acceleration are generated, so that constant-current motion of the air particles is ensured. According to the electromagnetic shaftless vortex blade centripetal type high-pressure fan, impact force between fluid and the blades is avoided; flexible application can be achieved, air supply pressure is improved through a series connection device, and the air supply capacity is improved through a splicing device; electricity consumption is saved by 8% under the same power, the air pressure is increased by 30% or more, and the air volume is increased by 50% or more; and therefore, and the advantage of high work efficiency is achieved.

Description

technical field [0001] The invention belongs to the technical field of high-strength, low-noise, centripetal high-pressure blower, and in particular relates to an electromagnetic shaftless vortex-blade centripetal high-pressure blower. It is suitable for mine high-pressure fans. Background technique [0002] Traditional fans include: volumetric type, which uses the periodic change of the volume of the working chamber to deliver the air volume; blade type, which uses the centrifugal force generated by the interaction between the blade and the air volume body and the high-speed rotation of the impeller to send the air volume to other places. Most of the current fans are in the form of short strokes. The key is that the structure of the high-pressure fan is unreasonable, and there are disadvantages such as low wind force, high power consumption, and high noise during use. [0003] To sum up, the problems existing in the prior art are: the traditional fan is separated from the ...

AI Technical Summary

Problems solved by technology

[0003] To sum up, the problems existing in the prior art are: the traditional fan is separated from the generator body, the single blade of the fan (air pump) works in a short stroke, the contact time between the particles of the wind body and the blade is small, the acceleration force is small, and it cannot work continuously. Large impact force with wind particles, large power consumption, low work efficiency, low power generation, high noise, waste of resources and other disadvantages, the key lies in the unreasonable structure of the fan (air pump)
