Embodiment Construction

[0022] like Figure 1 to Figure 7 As shown, an explosion-proof frequency conversion energy-saving centrifugal fan includes a cylindrical shell 1, an impeller 2 is arranged inside the shell 1, and a motor for driving the impeller 2 to rotate is fixedly installed on the outside of one end of the shell 1. The drive motor 3, the outer side of the other end of the housing 1 is fixedly installed with the air inlet pipe 4 communicating with the inner cavity of the housing 1, and the outer peripheral surface of the housing 1 is fixedly installed with the The inner cavity of the body 1 is connected to the air outlet pipe 5; the driving motor 3 drives the impeller 2 to rotate, and when the impeller 2 rotates, the air is sucked into the housing 1 from the air inlet pipe 4 and then discharged from the air outlet pipe 5. The air outlet pipe 5 extends laterally, and two deflectors 6 are arranged up and down oppositely in the air outlet pipe 5, and one ends of the two deflectors 6 are respec...

Abstract

The invention relates to the field of fans, in particular to an anti-explosion frequency conversion and energy saving centrifugal ventilator. Two flow guide plates are arranged in an air outlet pipe oppositely up and down, and two parallel adjusting plates are further arranged in the air outlet pipe oppositely up and down. A connecting mechanism used for driving the adjusting plates to move up anddown is arranged on the air outlet pipe. Multiple parallel flow guide blades are arranged in the air outlet pipe side by side left front and back. Small shafts are rotationally mounted in through holes. Long-strip-shaped holes extending in the vertical direction are arranged on the small shafts. An adjusting mechanism used for driving the flow guide blades to rotate is arranged on the air outletpipe. According to the anti-explosion frequency conversion and energy saving centrifugal ventilator, the distance between the two adjusting plates is reduced by moving the two adjusting plates inwards, so that the pressure of wind exhausted between the two adjusting plates is increased, or the distance between the two adjusting plates is increased by moving the two adjusting plates outwards, so that the pressure of wind exhausted between the two adjusting plates is reduced; and in addition, the direction of wind exhausted between the two adjusting plates is adjusted by rotating and adjusting the multiple flow guide blades, and adjusting is convenient.

Description

technical field [0001] The invention relates to the field of fans, in particular to an explosion-proof frequency conversion energy-saving centrifugal fan. Background technique [0002] Explosion-proof frequency conversion energy-saving centrifugal fan is a machine that relies on input mechanical energy to increase gas pressure and discharge gas. It is a driven fluid machine. Explosion-proof variable frequency energy-saving centrifugal fans are widely used in ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings; ventilation and drafting of boilers and industrial furnaces; air conditioning equipment and household electrical appliances Cooling and ventilation in the center; drying and selection of grain; wind tunnel wind source and inflation and propulsion of hovercraft, etc. The existing explosion-proof frequency conversion energy-saving centrifugal fan has a bulky body, and the air outlet direction is not easy to a...
