Abstract

The invention discloses a backward-tilting multi-wing centrifugal ventilator. The backward-tilting multi-wing centrifugal ventilator comprises a ventilator main body, wherein an explosion-proof motoris fixedly arranged on the outer surface of one side of the ventilator main body; a worm board is arranged at one side of the explosion-proof motor; a current collector is arranged inside the worm board; an impeller is fixedly arranged inside the current collector; a rotating shaft is arranged at the center inside the impeller; in addition, fan wings are fixedly arranged on the outer surface of the rotating shaft; a vertical baffle is fixedly arranged at the center of the outer surface at one side of each fan wing; a connecting port is formed in the upper end of the outer surface of one side of the worm board; an operation box is arranged on the outer surface of one side, close to the connecting port, of the worm board. The backward-tilting multi-wing centrifugal ventilator disclosed by the invention is provided with the vertical baffles, a dust outlet and a filtering plate; a suction force and a centrifugal force can be improved and an operation process is facilitated; in addition, air can be filtered and finally dust can be collected and discharged, so that a dust raising effect is effectively avoided and a better use prospect is brought.

Description

technical field [0001] The invention relates to the field of multi-blade centrifugal fans, in particular to a backward inclined multi-blade centrifugal fan. Background technique [0002] The multi-blade centrifugal fan is a machine that relies on input mechanical energy to increase gas pressure and discharge gas. It is a driven fluid machine. According to the principle of converting kinetic energy into potential energy, the high-speed rotating impeller is used to accelerate the gas, then decelerate and change the flow direction to convert kinetic energy into potential energy. In a single-stage centrifugal fan, the gas enters the impeller from the axial direction, changes direction as the gas flows through the impeller, and then enters the diffuser. In a diffuser, the gas changes direction of flow causing a deceleration, which converts kinetic energy into pressure energy. The increase in pressure occurs mainly in the impeller and secondarily in the diffusion process. In th...
