Abstract
The utility model discloses a low noise pipeline centrifugal fan, include a box and install a core in the box, the box includes mutually perpendicular's trilateral frame bounding wall, a frame apron and a frame panel, the trilateral frame bounding wall of integrated into one piece of bending after the frame bounding wall is made the air outlet by galvanized steel sheet through the laser cutting unloading, the integrated into one piece of bending after the frame panel is made the air outlet by galvanized steel sheet through the laser cutting unloading. Adopted the utility model discloses a low noise pipeline centrifugal fan owing to pass through the monoblock galvanized sheet and roll over into a frame bounding wall through the bender, directly through the unloading on the frame panel the shaping of bending of air outlet an organic whole simultaneously, has saved the material, has simplified production processes, has improved production efficiency, has reduced manufacturing cost.
Description
Technical Field
The utility model relates to a ventilation equipment, specific saying so relates to a low noise pipeline centrifugal fan, belongs to fan and ventilation equipment field.
Background
The low-noise pipeline centrifugal fan is mainly used for ventilation in hotels, shopping malls, movie theaters, dance halls and civil buildings. At present, the outer frame of the civil low-noise pipeline centrifugal fan is generally spliced by 4 independent frame plate coamings, an angle head is needed, multiple materials such as sectional materials, coamings and air outlets are needed, the process is complicated, and the production cost is high.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects, the utility model aims at providing a low noise pipeline centrifugal fan with simplified assembly and lower cost.
In order to achieve the above object, the utility model adopts the following technical scheme: the utility model provides a low noise pipeline centrifugal fan, includes a box and installs a core in the box, the box includes three frame bounding walls of mutually perpendicular, a frame apron and a frame panel, the frame bounding wall is bent integrated into one piece's three frame bounding walls by a monoblock galvanized steel sheet behind the laser cutting unloading, the frame panel is bent integrated into one piece behind the air outlet is made to the galvanized steel sheet through the laser cutting unloading.
The inner sides of the outer frame coaming, the outer frame cover plate and the outer frame panel are respectively pasted with silencing cotton, the movement and the outer frame coaming are fixed through cone tail screws, the outer frame cover plate and the outer frame coaming are fixed through cone tail screws, and the outer frame panel and the outer frame coaming are fixed through cone tail screws.
The outer frame coaming is riveted with 8 angle yards respectively at bent air outlet, the top of outer frame coaming is adopted
4 lifting rings are fixed by conical tail screws.
Adopted the utility model discloses a low noise pipeline centrifugal fan owing to pass through the monoblock galvanized sheet and roll over into a frame bounding wall through the bender, directly through the unloading on the frame panel the shaping of bending of air outlet an organic whole simultaneously, has saved the material, has simplified production processes, has improved production efficiency, has reduced manufacturing cost.

Detailed Description
The first embodiment is as follows: the outer frame coaming 2 is formed by bending after laser blanking according to figure 2. The outer frame cover plate 3 is formed by bending after laser blanking according to the figure 3. The outer frame panel 4 is formed by bending after laser blanking according to the figure 3. Silencing cotton 7 is respectively stuck on the inner sides of the outer frame coaming 2, the outer frame cover plate 3 and the outer frame panel 4. The movement 1 and the outer frame coaming 2 are fixed by adopting taper tail screws, the outer frame cover plate 3 and the outer frame coaming 2 are fixed by adopting taper tail screws, and the outer frame panel 4 and the outer frame coaming 2 are fixed by adopting taper tail screws. 8 angle sign indicating number 5 is riveted with frame bounding wall 2 bending 8 air outlets respectively. 4 rings 6 and outer frame bounding wall 2 adopt the taper tail screw to fix, accomplish the fan assembly.
The utility model discloses a low noise pipeline centrifugal fan's another innovation point lies in frame bounding wall 2, frame apron 3, frame panel 4 need not use the pistol drill to carry out the flange hole again to dryer 4 in assembly process, draw forth the operation in hole.
The utility model discloses a low noise pipeline centrifugal fan's another innovation point mainly lies in frame bounding wall 2, frame apron 3, frame panel 4 inboard all posts amortization cotton 7, greatly reduced the noise when fan operation.
The utility model discloses a low noise pipeline centrifugal fan's another innovation point mainly lies in low noise pipeline centrifugal fan outer frame panel 2, frame apron 3, frame panel 4 adopt the laser unloading, and the one shot forming of bending, it is convenient to assemble.
