Description
Technical field
The utility model relates to a kind of abutment wall blower fan.
Background technique
Blower fan is the abbreviation to gas compression and gas conveying machinery, and usually said blower fan comprises ventilator, blower and wind-driven generator.Gas compression and gas conveying machinery are that the mechanical energy rotated is converted to gas pressure energy and kinetic energy, and the machinery that gas is transferred out.The main structural components of blower fan is impeller, casing, intake grill, support, motor, belt pulley, coupling, baffler, driving component (bearing) etc.
Blower fan can divide several, as iron-clad blower fan (common blower fan), fiberglass blower fan, plastic fan, aluminium blower fan, stainless steel blower fan etc. by the classification of use material.Blower fan classification can by the direction of gas flow, is divided into the types such as centrifugal, axial flow, diagonal flow type (mixed-flow) and cross-flow type.Centrifugal blower, air stream axle mainly radially flows after the impeller entering blower fan, and this kind of blower fan is made according to the principle of centrifugal action, and product comprises centrifugal blower, centrifugal blower and centrifugal compressor.Axial-flow blower, air stream axle, to the impeller entering blower fan, flows in the axial direction approx on barrel surface, and this kind of blower fan comprises propeller fan, axial flow blower and axial flow compressor.Revolution blower fan, utilize rotor to rotate and change gas chamber volume to carry out work, common kind has Roots blower, rotary compressor.
In the prior art, conventional abutment wall blower fan is integrated type, for body of wall installation by adhering, there is an inevitable problem in blower fan, is exactly that the thickness of blower fan entirety can not fit like a glove the thickness of body of wall, be not thickness low LCL be exactly that thickness is oversize, when blower fan thickness is less than thickness of wall body, outstanding body of wall section easily piles up foreign material and dust, reduce drafting efficiency, the foreign material simultaneously piled up easily suck in blower fan, affect the normal operation of blower fan.
Model utility content
The purpose of this utility model is to provide a kind of abutment wall blower fan; its structure is simple; easy for installation; flow blower casing is movably connected by L-type slide bar and safety cover can the integral thickness of free adjusting blower fan; and the setting of supporting post substantially increases the soundness of blower fan, thus improve the working life of blower fan.
In order to achieve the above object, the technical solution of the utility model is:
A kind of abutment wall blower fan; comprise flow blower casing; described flow blower casing comprises intake grill, exhaust outlet; in described flow blower casing, motor is installed; described motor is connected with impeller; the first chute, the second chute is offered respectively in flow blower casing between described motor and intake grill; first L-type slide bar is installed in wherein said first chute; second L-type slide bar is installed in described second chute; the flow blower casing of described intake grill end is provided with safety cover, and described safety cover is connected with the first L-type slide bar, the second L-type slide bar respectively.
Be provided with the first supporting post in described first chute, described first supporting post is connected with the first L-type slide bar, safety cover respectively; Be provided with the second supporting pillar in described second chute, described second supporting pillar is connected with the second L-type slide bar, safety cover respectively.
Described flow blower casing inwall is provided with silencing cotton.
In the first chute of described motor side, the first limiting stopper is installed, is provided with second soon spacing in the second chute of described motor side.
Described safety cover offers positioning hole.
The beneficial effects of the utility model are: a kind of abutment wall blower fan; its structure is simple; easy for installation; flow blower casing is movably connected by L-type slide bar and safety cover can the integral thickness of free adjusting blower fan; and the setting of supporting post substantially increases the soundness of blower fan, thus improve the working life of blower fan.
