Abstract
The utility model relates to an adjustable axial-flow fan, composed of a machine shell, blades, a supporting bolt, an impeller hub, an air gathering machine, a motor, a supporting bracket, a pressing plate, etc. Due to the fact that the blades are installed between the upper wheel boss and the lower wheel boss of the impeller hub, the blades can be optionally assembled and disassembled in the impeller hub; the angle of the blades can be optionally adjusted in the impeller hub; therefore, different air quantity and air pressure can be produced as required. The utility model has the advantages of convenient replacement and convenient maintenance. When running, the utility model is stable and equalized; wind can flow in the positive direction and the opposite direction; the integral structure of the adjustable axial-flow fan can be movably assembled and disassembled.
Description
The utility model relates to a kind of blower fan, particularly a kind of adjustable axial-flow blower fan.
Fan blade and wind wheel wheel hub in the existing axial-flow blower all are solder bond, can not adjust, and blade can only unidirectionally be fixed, and wind direction can only one-way flow; And damage as a blade, then need change whole wheel member, cause waste.The blower fan overall structure only is a kind of form in addition, narrow application range.
The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part and a kind of blade and impeller hub are provided is adjustable movable the combination, adjustable axial-flow blower fan flexible and convenient to use, applied widely.
The purpose of this utility model can reach by following measure: the utility model comprises by casing, stay bolt, wind collecting unit, motor, bearing support, pressing plate, it is characterized in that: every movable being loaded on the impeller hub of blade, the movable folding of impeller hub.
The purpose of this utility model can also reach by following measure: impeller hub is divided into wheel hub and lower hub two-part, pass through bolton between the upper and lower wheel hub, blade can be hidden between the upper and lower wheel hub in the formed cavity, and the angle of regulated at will blade within it, last wheel hub and lower hub all adopt the moulding of ZL104 aluminium alloy compression casting.Blade is wing formula, spatial warping shape, and adopts the moulding of ZL104 aluminium alloy compression casting, and the root of blade indicates scale.Wind collecting unit, bearing support be by being bolted on the casing, movable mounting or dismounting, and wind collecting unit can be loaded on the another side of casing.
Fig. 1 is a structure front view of the present utility model;
Fig. 2 is structure side-looking of the present utility model (broken section) figure;
Fig. 3 is the structure front view of last wheel hub;
Fig. 4 is the structure front view of lower hub;
Fig. 5 is the structure side view of lower hub;
Fig. 6 is the structure front view of blade;
Fig. 7 is the structure side view of blade.
The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):
With reference to Fig. 1～Fig. 7, the utility model is made up of casing 1, blade 2, stay bolt 3, impeller hub 4, wind collecting unit 5, motor 6, bearing support 7, pressing plate 8 and nut, screw etc.Impeller hub 4 is divided into wheel hub 9,10 two symmetric parts of lower hub, can pass through bolton between the upper and lower wheel hub, so that the angle of transferring than blade 2 is installed.The root of blade 2 can be loaded between the upper and lower wheel hub in the formed cavity, and it is shaped as wing formula, spatial warping shape, and root has scale, can according to different require to transfer than the angle of blade 2 produce different airflow pressures.Blade 2 can two-wayly be installed (as long as unclamp between the upper and lower wheel hub bolt), and wind direction can flow in the other direction.When blade damages, can change by monolithic in addition, reduce the loss, in order to maintenance.Blade 2 and impeller hub 4 all adopt the manufacturing of ZL104 aluminum alloy, can reach general explosion-proof using effect.Wind collecting unit 5, bearing support 7 are by being bolted on the casing 1, and movable dress is rolled over, and standard type is an on-land type; Remove bearing support and can become in-wall; As wind collecting unit 5 is also removed, then can become pipe type.Wind collecting unit 5 also can be loaded on the another side of casing 1 in addition, to cooperate the change of the wind of blade.
The utility model has following advantage compared to existing technology:
1. blade can arbitrarily be adjusted angle and mounting or dismounting on impeller hub, requires to produce different airflow pressures thereby can comply with, and is beneficial to repair and replacement.
When operation steadily balanced, wind-force can positive and negative two directions flow, and the blower fan overall structure is movable mounting or dismounting form, and is applied widely, rational in infrastructure, good looking appearance.
Claims (4)
