Description
Technical field
This utility model relates to a kind of quiet pressure fan.
Background technology
At present, the utilization of industrial pressure fan is relatively wide, but the high pressure fan often noise of power is relatively big, causes working environment to be polluted by noise, how to make pressure fan realize the problem that sound insulation, noise reduction and power more always perplex industry.
Utility model content
Therefore, for above-mentioned problem, the utility model proposes a kind of simple in construction, can preferably realize the quiet pressure fan of sound insulation and noise reduction.
For achieving the above object; this utility model have employed techniques below scheme: a kind of quiet pressure fan; the mounting cylinder including base, being located on base, the taper air funnel being located at mounting cylinder front end, air supply motor; described air supply motor is set up in the middle part of mounting cylinder by propping up; the rotating shaft of described air supply motor is provided with blade; the inwall of described taper air funnel is provided with a protection board; being provided with 3D screen cloth between described protection board and taper air funnel, described protection board is provided with a thread groove running through protection board.
Further, two sides of described thread groove are along offering circular arc chamfering respectively.
Further, described mounting cylinder is provided with protection network away from one end of taper air funnel.
Further, described support is provided with the conical ring for water conservancy diversion.
By using preceding solution, the beneficial effects of the utility model are: this quiet pressure fan, by arranging a taper air funnel, realize the concentration to wind-force, then utilize thread groove to realize the absorption to vibration and the wind-force impact to taper air funnel when air-supply, then utilize 3D screen cloth to carry out the absorption vibrated, the absorption of wind-force, thus realize reducing the purpose of noise, reach muting function；Further, by arranging circular arc chamfering, reduce the impact of wind-force so that vibrating less, noise is less；Further, by arranging protection network, can effectively stop foreign material, and prevent injury to personnel；Further, by arranging conical ring, it is possible to achieve the water conservancy diversion of wind-force, so that more wind can be close to the inwall of taper air funnel and send, and during sending, easily form eddy current, strengthen the effect of air-supply, reduce the impact to taper air funnel.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of thread groove.
Detailed description of the invention
In conjunction with the drawings and specific embodiments, this utility model is further illustrated.
With reference to Fig. 1, Fig. 2; the present embodiment provides a kind of quiet pressure fan; the mounting cylinder 2 including base 1, be located on base 1, it is located at the taper air funnel 3 of mounting cylinder 2 front end, air supply motor 4; described air supply motor 4 is located at the middle part of mounting cylinder 2 by support 5; the rotating shaft of described air supply motor 4 is provided with blade 6; the inwall of described taper air funnel 3 is provided with a protection board 7; being provided with 3D screen cloth 8 between described protection board 7 and taper air funnel 3, described protection board 7 is provided with a thread groove 71 running through protection board 7.Two sides of described thread groove 71 are along offering circular arc chamfering 72 respectively.Described mounting cylinder 2 is provided with protection network 21 away from one end of taper air funnel 3.Described support 5 is provided with the conical ring 9 for water conservancy diversion.
This quiet pressure fan, by arranging a taper air funnel, realize the concentration to wind-force, thread groove is then utilized to realize the absorption to vibration and the wind-force impact to taper air funnel when air-supply, then 3D screen cloth is utilized to carry out the absorption vibrated, the absorption of wind-force, thus realize reducing the purpose of noise, reach muting function；Further, by arranging circular arc chamfering, reduce the impact of wind-force so that vibrating less, noise is less；Further, by arranging protection network, can effectively stop foreign material, and prevent injury to personnel；Further, by arranging conical ring, it is possible to achieve the water conservancy diversion of wind-force, so that more wind can be close to the inwall of taper air funnel and send, and during sending, easily form eddy current, strengthen the effect of air-supply, reduce the impact to taper air funnel.
Although specifically showing in conjunction with preferred embodiment and describing this utility model; but those skilled in the art should be understood that; in the spirit and scope of the present utility model limited without departing from appended claims; this utility model can be made a variety of changes in the form and details, be protection domain of the present utility model.
