Abstract
The utility model discloses an axial-flow fan. The axial-flow fan comprises a housing, wherein the left wall of the housing is provided with an air inlet, and the right wall of the housing is provided with an air outlet; a motor and a wind wheel are arranged inside the housing; the motor comprises a rotating shaft connected with the wind wheel; the wind wheel comprises rotors; a demountable protective case is arranged outside the motor; an air exchange wheel is arranged, between the motor and the protective case, on the rotating shaft; a first air exchange pipe communicated with the outside of the housing is arranged at the front end of the protective case right above the air exchange wheel; a second air exchange pipe communicated with the outside of the housing is arranged at the top of the rear end of the protective case. According to the utility model, the axial-flow fan can prevent air from corroding the motor; simultaneously, the arranged air exchange wheel accelerates air flow, so that the motor efficiency is prevented from being reduced due to excess temperature of the motor, and the discharge velocity of etchant air is accelerated for further protection of the motor; the housing is arranged to be demountable, so that the protective case of the motor can be cleansed, the using effect of the motor is improved, and the motor is convenient to maintain.
Description
Technical field
The utility model relates to mechanical engineering field, especially relates to a kind of axial-flow blower.
Background technique
Traditional axial axis flow fan is directly arranged on motor in housing, and in the time that transmission has corrosive gas, the easily inner member of corrosion electrical motor, causes motor to damage, and even shortens the working life of motor, and then affects the using effect of blower fan.
Damage for fear of motor, the mode of existing protection motor is at the sheathed anti-corrosive cover of outside motor or spraying corrosion resistant coating, spraying corrosion resistant coating only shields to outside motor, and anticorrosive coat easily comes off and affect antiseptic effect, and corrosive gas still can enter in motor motor is corroded; And at the sheathed anti-corrosive cover of outside motor, anticorrosion gas can enter motor from thermovent and anti-corrosive cover finedraw, antiseptic effect is not good, and anti-corrosive cover also can affect the radiating effect of motor simultaneously; Anti-corrosive cover removes and installs inconvenience.
Model utility content
The utility model is in order to overcome the deficiencies in the prior art, and a kind of axial-flow blower of anticorrosion and good heat dissipation effect is provided.
To achieve these goals, the utility model by the following technical solutions: a kind of axial-flow blower, comprise casing, the left wall of described casing is provided with intake grill, right wall is provided with exhaust outlet; In described casing, be provided with motor and wind wheel; described motor comprises the rotating shaft that connects wind wheel; wind wheel comprises rotor; described outside motor is provided with a detachable protective shell; rotating shaft is provided with a ventilation wheel between motor and containment vessel; the front end of containment vessel is positioned to be provided with directly over ventilation wheel and is communicated with first of casing outside and changes airduct, and the top, rear end of containment vessel is provided with and is communicated with second of casing outside and changes airduct.
As preferably, described first changes airduct and the second end of changing airduct is provided with mounting hole, is equipped with the scaffold of T shape in mounting hole, and this scaffold comprises the longitudinal fixing part that is positioned at the horizontal head of passage and is connected with housing upper surface through mounting hole.
In sum, the utlity model has following advantage: this is arranged on and transmits while having corrosive gas, can avoid gas attack motor, ventilation wheel being set simultaneously and having accelerated flowing of gas, avoid motor to reduce the efficiency of motor because of excess Temperature, also accelerated the velocity of discharge of corrosive gas simultaneously, further protect motor, housing has been arranged to detachably, can clean the containment vessel of motor, and then the using effect of raising motor, easy to maintenance; This fixing part is fixedly connected with housing upper surface by screw, and this setting removes and installs simply, is convenient to maintenance.
