Abstract
The utility model relates to a but lampblack absorber of amortization, including casing and spiral case, the spiral case sets up in the casing, the casing lower extreme is equipped with the import, the casing upper end is equipped with the export, be provided with motor and impeller in the spiral case, the side of spiral case is provided with the air intake, the spiral case upper end is provided with the air outlet, the air outlet communicates with each other with the export of casing, be provided with the acoustical panel on the relative casing inner wall of spiral case air intake, spiral case slope set up in the casing, the acoustical panel sets up on the casing inner wall, form the wind gap of acute angle between spiral case air intake one side and the acoustical panel, the wind gap sets up down. Add the acoustical panel to make the acoustical panel form the wind gap of acute angle on one side of the spiral case air intake, thereby make the air current that gets into in the casing and rely on acoustical panel noise abatement, improve the mute function of whole lampblack absorber fast by in the introduction spiral case.
Description
Technical field
The utility model relate to a kind of can the lampblack absorber of noise reduction.
Background technology
In existing centrifugal blower, the air intake of spiral case mainly relies on the air inlet being opened in side, and the air-flow be sucked in casing needs then just can enter in spiral case through several bending, and therefore conventional centrifugal blower fan exists turbulence noise.
Utility model content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provide a kind of can the lampblack absorber of noise reduction.
The utility model solves the technical scheme that its technical problem adopts: a kind of can the lampblack absorber of noise reduction, comprise casing and spiral case, described spiral case is arranged in casing, described casing lower end is provided with import, and described casing upper end is provided with outlet, is provided with motor and impeller in described spiral case, the side of described spiral case is provided with air inlet, described spiral case upper end is provided with air outlet, and described air outlet communicates with the outlet of casing, and the casing inner wall that described spiral case air inlet is relative is provided with acoustical panel; Described spiral case is obliquely installed in casing, and described acoustical panel is arranged on casing inner wall, and the acutangulate air port of shape between described spiral case air inlet side and acoustical panel, described air port is arranged down.
Further, described acoustical panel is connected with casing inner wall through at least one joint pin.
Further, one end that described acoustical panel is used for being connected with joint pin is also provided with electric heating film.
Further, described electric heating film is mica electrical heating membrane, comprise heating layer, the first mica layer and the second mica layer, the first described mica layer and the second mica layer are separately positioned on the both sides of heating layer, described first mica layer is connected with the back side of acoustical panel, the side of described second mica layer is provided with reflectance coating, and the arranged outside of described reflectance coating has the 3rd mica layer.
Further, described heating layer compacting to be bonded between the first mica layer and the second mica layer and to form overall structure.
Further, described reflectance coating is aluminium flake or aluminium plating zinc plate.
The beneficial effects of the utility model are: set up acoustical panel, and make acoustical panel and the acutangulate air port of shape, spiral case air inlet side, thus the air flow energy entered in casing is introduced in spiral case fast, and rely on acoustical panel to reduce noise, improve the mute function of whole lampblack absorber.
Secondly, rely on the electric heating film being arranged on the acoustical panel back side can heat acoustical panel, dissolve the oil being adsorbed on acoustical panel front, guarantee the noise reduction quality of acoustical panel.
