Abstract

The utility model relates to a low-noise cylindrical fan which comprises a housing, guide vanes, an impeller, a current collector, and a motor. The utility model is characterized in that an elastic cushion is installed at the connecting position of the guide blades and the fan housing, and the elastic cushion, the guide blades and the fan housing are connected through connecting pieces; a silencing heat-insulating layer and a perforated plate are arranged on the periphery of the motor; a silencing flow baffle plate is arranged in the front of the impeller. The utility model has the advantages of small size, small ground occupation, easy installation, suspending installation, silencing and heat insulating method on the structural design, cost saving, and a vibration damping platform doesn't need to be provided. Simultaneously, the adjusting installation of a machine core can be carried out according to the angles of the blades and the material conditions.

Description

Low noise cartridge type blower fan
The utility model belongs to a kind of centrifugal fan, particularly a kind of low noise cartridge type blower fan.
The centrifugal fan of ventilation system use at present adopts belt transmission, and floor space is big, and difficulty is installed, and noise is big, in order to reduce vibrations vibration-damped table need be set, and expense is higher; The blower fan Way out is subjected to revolve about impeller restriction simultaneously, can only be put on the ground, can not lift; Installation can not be adjusted in the position of movement.
The purpose of this utility model provides a kind of low noise cartridge type blower fan, and volume is little, and floor space is little, installs easily, also can lift, and has on structural design and eliminates the noise and heat insulation measures, and vibration-damped table needn't be set, and reduces expenses; Can install according to the adjustment that the angle and the material situation of blade are carried out movement simultaneously.
The purpose of this utility model is achieved in that it comprises casing, stator, impeller, slip ring and motor, and its technological scheme main points are: assembling elastic insert in joint between stator and the flow blower casing, and the three adopts coupling affixed; In the motor periphery noise elimination thermal-protective coating and the perforation utmost point are set; The noise elimination baffle utmost point is set in impeller the place ahead.
The utility model has the advantages that: be designed to cylindrical structure, volume is little, and floor space is little, installs easily, also can lift, and saves floor space.Take the heat insulation measures of eliminating the noise on structural design, noise is little, and motor is installed in the casing, even make boiler induced-draft fan, high temperature reaches 250 ℃ also can proper functioning; Vibration-damped table need not be set, cost saving; Because stator and shell adopt Bolt Connection, can install according to the adjustment that the angle and the material situation of blade are carried out movement.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural representation.
Fig. 2 is the A-A sectional view of Fig. 1.
See Fig. 1,2, concrete structure is as follows: assembling stator 7 between the flow blower casing 3 of cartridge type and the motor sound proof housing 11; Assembling elastic insert 6 between the outer rim of stator 7 and the flow blower casing 3 connects by bolt 8 between the three.Stator 7 inner edges and 11 welding of motor sound proof housing.Assembling motor 12 in the sound proof housing 11, the noise elimination thermal-protective coating 9 and the perforated plate 10 of the superfine glass silk flosssilk wadding that is fixedly connected in interior week of sound proof housing 11.The affixed impeller 13 of the front end of motor shaft; Slip ring 14 is fixedly connected at the front end of flow blower casing 3 by disc 2.Front end in fan passage is provided with noise elimination flow-stopping plate 1, and noise elimination flow-stopping plate 1 is by the front portion of Bolt Connection at flow blower casing.Noise elimination thermal-protective coating 4 and perforated plate 5 are fixedly connected on the noise elimination flow-stopping plate 1.
