Description
Technical field
The utility model relates to a kind of air cleaning units, and in particular to a kind of new blower of mute type.
Background technique
The main noise of blower is that source has at present: (1) noise of motor: the electricity as used by practical blower manufacturer
Owner will be provided by motor manufacturer, and blower manufacturer does not make too many noise-reducing processing, including rotor unbalance generally
Or the aerodynamic noise etc. that the axial motion sound of electromagnetic force axial component generation, motor cooling fan generate can all make motor
Or even blower generates very big noise, and the noise of motor unless using high price mute motor, be otherwise substantially difficult to avoid that
's；Or because discharge air-flow and the volute tongue interaction of impeller generate the noise caused by trembling；(2) mechanical noise of ventilation blower: by
It is uneven or because wind pressure leads to the deformation of part in damage in impeller, make entire rotor unbalance and the noise that generates；Or because of bearing
After operation due to abrasion, the noise mutually generated with axis；Or it is generated due to the connection of bad or each part loosens because due to installing
Noise；Or because impeller high speed rotation generates vibration, lead to a certain partial resonance of body and the noise that generates.
Existing new blower drops to noise in the range of human ear can bear to inhibit to resonate, currently used in the industry
Method is to increase metal plate thickness, however, increasing metal plate thickness not only will increase consumptive material, is increased so as to cause manufacturing cost, and
It can not inhibit to resonate well, noise caused by being resonated by metal plate is still obvious.Because motor generally passes through motor branch
Frame is fixed on volute, and its shaft is usually parallel with metal plate housing bottom surface, so at work, due to the work of centrifugal force
With metal plate can resonate, and noise is larger.
The problem of current blower new on the market causes higher noise there is also air flowing.Although reducing fan noise
Main method is the structure of reasonable adjustment volute tongue and impeller mostly, but two methods have some limitations at present,
It will increase energy consumption while reducing noise or reduce the performance of blower.
Utility model content
Technical problem to be solved in the utility model is to overcome drawbacks described above of the existing technology, provides a kind of ring
Energy conservation is protected, it is at low cost, it keeps original fan performance and does not increase the pollutant purification that can be achieved in room air of energy consumption
The new blower of mute type.
It is as follows that the utility model solves technical solution used by its technical problem: 1, the new blower of a kind of mute type, including
Shell (5), purification device and centrifugal blower (6), the shell (5) are hexahedron, including are four sides, a top surface and one
A bottom surface, a pair of side therein are respectively equipped with opposite air inlet (1) and air outlet (7), and housing central section is purifying area, purification
The rear end in area is the area Feng Xi, which is characterized in that >=3 pieces of removable filter plates (3) is equipped in purifying area, on filter plate (3)
Equipped with filtering net film；The front end of purifying area is equipped with sound-absorbing area, is provided with acoustical cotton (2) on the inside of sound insulation area, centrifugal blower (6) and
Sound insulation damping device (4) are installed at filter plate (3) and cage connection；Sound insulation damping device (4) is rubber damper and damping
Spring cushion, the sound insulation damping device are arranged symmetrically by the central axes of shell (5).
Further, the air inlet and air outlet are connected with flexible duct.
Further, the shell uses aluminum alloy frame, galvanized sheet structure.
When the utility model is used, indoor contaminated air is taken out by flexible duct from air inlet using centrifugal blower
Into sound insulation area, the acoustical cotton in sound-absorbing area absorbs the voice parts that the air flowing of air inlet issues, around centrifuge
Sound insulation damping device can slow down the vibration of blower and shell including rubber damper or damping spring shock absorber, sound
It can be blocked inside the shell, noise will not be generated outward.In addition, utilizing the rubber item wrapped up on filter plate edge in purifying area
The vibration between filter plate and filter plate between filter plate and shell can be slowed down.
The utility model the utility model has the advantages that the utility model since intake stack, until after air inlet enter buffer area, purification
Area and the area Feng Xi come out the noise just generated to air flowing from air outlet and carry out a series of silencing and damping processing, it is ensured that this reality
With the mute operation of novel realization, in addition, to the component of new blower interior also take sound insulation damping device such as rubber damper or
The mechanical noise of blower is slowed to floor level by damping spring shock absorber, and rubber item between filter plate.
Detailed description of the invention
Fig. 1 is the utility model embodiment structural schematic diagram；
In figure: 1, air inlet；2, acoustical cotton；3, filter plate；4, sound insulation damping device；5, blower housing；6, centrifugal blower；
7, air outlet.
Specific embodiment
Below with reference to embodiment and attached drawing, the utility model is described in further detail.
Embodiment
The new blower of the present embodiment mute type, including shell, purification device and centrifugal blower 6, the shell are hexahedron, packet
It including as four sides, a top surface and a bottom surface, a pair of side therein is respectively equipped with opposite air inlet 1 and air outlet 7,
Housing central section is purifying area, and the rear end of purifying area is the area Feng Xi, is equipped with 3 blocks of removable filter plates 3, filter plate in purifying area
3 are equipped with filtering net film；The front end of purifying area is equipped with sound-absorbing area, is provided with acoustical cotton 2,6 He of centrifugal blower on the inside of sound-absorbing area
