Abstract

The invention relates to an axial-flow fan with large air amount and high wind speed. A fan base is composed of an inner ring, a middle ring, a fan base blade, a shell and a reinforcing rib and cast into a whole; the inner ring and the middle ring are connected by the reinforcing rib; the middle ring and the shell are connected by the fan base blade; the fan base forms a three-layer cavity by the shell, the inner ring and the middle ring; a stator is assembled on the inner ring of the fan base; a rotor spindle is arranged on a bearing; an impeller is composed of an impeller body and an impeller blade connected with the impeller body; the impeller is arranged on a rotor shaft; the impeller blade is designed into a rotor wing shape; and the energy of the gas ascends due to thrust of the blade on the impeller, so that the wind is large in air amount and high in wind speed. The fan base blade is designed into a shaft bushing shape and arranged at the position of an air outlet at the bottom part of the fan base; and axial flowing air is supercharged again, so that the wind forms a spiral shape, so as to achieve high air pressure, large air quantity and fast wind speed. The axial-flow fan has the characteristics of large air quantity, high wind speed, small size, light weight, small noise, convenience in installation and dismantle, and simple structure.

Description

Wind Volume high wind speed axial-flow blower
Technical field: the present invention relates to a kind of Wind Volume high wind speed axial-flow blower.
Background technique: current axial-flow blower is by motor, impeller, casing forms, blade generally all can rotation angle, major part axial-flow blower is all furnished with a set of vane controlling device, complex structure, and maintenance is inconvenient, this axial-flow blower only has impeller blade to provide wind regime, blast is low, and air quantity is little, wind speed is slow, the occasion of can not meet the demands Wind Volume, high wind speed.Such as, the cooling blower of railway traffic linear motor.
Summary of the invention: the object of this invention is to provide that a kind of air quantity is large, wind speed is fast, noise is little, easy installation and removal, structure simple Wind Volume high wind speed axial-flow blower.Technological scheme of the present invention is: support is by inner ring, middle ring, support blade, housing, stiffening rib forms, and be cast as one, connected by stiffening rib between inner ring and middle ring, middle ring is connected by support blade with between housing, support is by housing, inner ring, middle ring forms three layers of cavity, stator is assembled in support inner ring, rotor main shaft is arranged on bearing, impeller is made up of impeller body and the impeller blade that is connected with impeller body, and be cast as one, impeller is arranged on rotor shaft, fix with bolt, impeller blade is designed to rotor shape, support blade design becomes bearing shell shape, be positioned at the position of exhaust outlet bottom support.
Working principle of the present invention:
When the impeller is rotated, gas axially enters impeller from intake grill, gas is subject to pushing and the energy of gas being raised of impeller upper blade, then flow in housing and middle ring cavity, deflect airflow is become axial flow by blade, flow into support blade, and support blade is by the supercharging again of the wind of axial flow, wind is formed spiral-shaped, more directly kept watch by support blade and be blown in air compartment.
Technique effect of the present invention:
1, impeller blade is designed to rotor shape, and gas is subject to pushing and the energy of gas being raised of impeller upper blade, makes wind form Wind Volume, high wind speed.
2, support blade design becomes bearing shell shape, is positioned at the position of exhaust outlet bottom support, by the supercharging again of the wind of axial flow, wind is formed spiral-shaped, and formation blast is high further, air quantity is large, wind speed is fast.
3, support forms three layers of cavity by housing, inner ring, middle ring, makes blower fan volume little, lightweight.
4, support is designed to be made up of inner ring, middle ring, support blade, housing, stiffening rib, and is cast as one; Impeller Design becomes to be made up of impeller body, impeller blade, and is cast as one, makes fan noise little, and installation, convenient disassembly, structure is simple.
Accompanying drawing illustrates:
Fig. 1 is the overall sectional view of the present invention.
Fig. 2 is the plan view of impeller of the present invention.
Embodiment:
As shown in Figure 1, a kind of Wind Volume high wind speed axial-flow blower, support 1 is made up of inner ring 2, middle ring 3, support blade 5, housing 6, stiffening rib 10, and be cast as one, connected by stiffening rib 10 between inner ring 2 and middle ring 3, middle ring 3 is connected by support blade 5 with between housing 6, and support 1 forms three layers of cavity by housing 6, inner ring 2, middle ring 3, make blower fan volume little, lightweight.Stator 4 is assembled in support inner ring 2, rotor 7 main shaft is arranged on bearing 8, as shown in Figure 2, impeller 12 is made up of impeller body 13 and the impeller blade 11 that is connected with impeller body 13, and is cast as one, impeller 12 is arranged on rotor 7 axle, fix with bolt, impeller blade 11 is designed to rotor shape, and gas is subject to pushing and the energy of gas being raised of impeller upper blade, wind is made to form Wind Volume, high wind speed.Support blade 5 is designed to bearing shell shape, is positioned at the position of exhaust outlet 9 bottom support, by the supercharging again of the wind of axial flow, wind is formed spiral-shaped, and formation blast is high further, air quantity is large, wind speed is fast.
The feature such as the present invention has Wind Volume, high wind speed, volume is little, lightweight, noise is little, easy installation and removal, structure are simple.
