Description
Technical Field
The utility model relates to a fan housing technical field, concretely relates to 56 cun negative pressure fan shell.
Background
The fan is a driven fluid machine which increases the gas pressure and discharges the gas by means of the input mechanical energy, is a short form of Chinese habit for gas compression and gas delivery machines, and generally comprises a ventilator, a blower and a wind driven generator.
At present, most of the existing 56-inch negative pressure fan shells adopt 90-degree vertical plane structures, and due to the fact that the negative pressure fan is used for exhausting air, air pumping and storage are easy to cause low pumping negative pressure efficiency, and the use efficiency of the 56-inch negative pressure fan shells is reduced.
SUMMERY OF THE UTILITY MODEL
Technical problem to be solved
In order to overcome the defects of the prior art, the 56-inch negative pressure fan shell is provided, and the problems that the pumping negative pressure efficiency is low and the use efficiency of the 56-inch negative pressure fan shell is reduced due to the fact that the air pumping is easily reserved and the pumping negative pressure efficiency is high when the negative pressure fan pumps air are solved.
(II) technical scheme
The utility model discloses a following technical scheme realizes: the utility model provides a 56 cun negative-pressure blower shell, including casing, arcwall face and cardboard, the casing inboard is provided with the arcwall face, the arcwall face top is provided with the cardboard, the arcwall face shaping in on the casing, the cardboard shaping in on the casing.
Furthermore, one side of the clamping plate is provided with a buckling groove.
Through adopting above-mentioned technical scheme, the catching groove is convenient to be installed the shutter.
Further, a frame is arranged on one side of the buckling groove, a protective frame is arranged on one side of the shell, and a fixing hole is formed in the upper portion of the protective frame.
Through adopting above-mentioned technical scheme, the frame can be consolidated negative-pressure air fan shell.
Further, the catching groove is formed on the shell.
Through adopting above-mentioned technical scheme, the casing can make the catching groove is fixed firm.
Further, the frame is formed on the shell.
By adopting the technical scheme, the frame can enable the shell to be firm.
Furthermore, the protective frame is formed on the shell.
By adopting the technical scheme, the protective frame can be used for conveniently installing the negative pressure fan.
Further, the fixing hole is formed on the protective frame.
By adopting the technical scheme, the fixing holes are convenient for fixing the negative pressure fan.
(III) advantageous effects
Compared with the prior art, the utility model, following beneficial effect has:
for solving present 56 cun negative-pressure air fan shell majority adopt 90 degrees perpendicular structures, because negative-pressure air fan when convulsions, make the air pumping reserve to cause greatly pumping negative pressure inefficiency easily, reduced 56 cun negative-pressure air fan shell availability factor's problem, the utility model discloses a set up casing and arcwall face, can make negative-pressure air fan pumping reserve for a short time, avoid the air pumping to reserve to cause greatly pumping negative pressure inefficiency, improved the efficiency that 56 cun negative-pressure air fan shell used.
