Abstract
The utility model relates to a flexible jointing box type cylinder fan which comprises a fan casing, a motor air inlet, a motor casing, a silencing heat-insulating layer in the motor casing, a perforated plate in the motor casing, a guide blade, a motor and a vane. The utility model is characterized in that: the inlet and outlet end of the fan casing is connected to both ends of a sound reducing enclosure through a flexible soft connecting ring; a circular channel is formed between the motor and the perforated plate of the motor casing; and a ventilation ring is fixedly connected with the front end of the motor.
Description
The utility model belongs to a kind of centrifugal blower, the box cartridge type blower fan of particularly a kind of resilient connection.
The centrifugal blower of installing and using at present, the dust and moisture of its motor will be selected motor according to service condition, thereby the blower fan using scope is restricted, noise is big during blower fan work, and motor is exposed in the Environmental Conditions, lower the temperature by natural heat dissipation, subject to humidity, dust infringement, influence its working life.
The purpose of this utility model provides the box cartridge type blower fan of a kind of resilient connection, uses common electric machine not to be subjected to use the ring mirror to limit, and effectively reduces noise, and can dust and moisture, good cooling effect.
The purpose of this utility model is achieved by the following technical solution: it comprises Fan casing, brings the motor casing in air port into, perforated plate, stator, motor and impeller etc. in noise elimination thermal-protective coating, the motor casing in the motor casing, it is characterized in that: the inlet/outlet end of Fan casing is connected in the two ends of silencer box by the soft coupling ring of elasticity, in motor and motor casing, constitute annular channel between the perforated plate, the venting ring of the affixed band ventilated port of the front end of motor.Working principle: by motor intake grill inspiration natural wind, and through annular channel and the venting ring between the perforated plate in motor and the motor casing, discharge from ventilated port vertically, simultaneously because axial ventilation, between impeller hub disk and motor front end, set up a low-temperature airflow district, effectively accelerate the discharge of motor heat, make common electric machine reach the effect of dust and moisture.Because silencer box is equipped with in the outside of blower fan and blower fan adopts the soft coupling of elasticity to be connected in the silencer box, it is effective to eliminate the noise.
The utility model is compared with prior art has following advantage: because blower fan adopts the soft coupling of elasticity to be connected in the silencer box, effectively reduce the noise of blower fan, adopt motor shaft to strengthen the motor ventilation amount to aeration structure, and between motor and impeller, set up a low-temperature airflow district, efficiently solve the cooling and the dust and moisture of common electric machine, using effect is good, prolongs the working life of motor.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the partial enlarged drawing that the motor front end is provided with venting ring.
Fig. 3 is the A-A sectional view of Fig. 1.
Fig. 4 is the left view of Fig. 1.
Fig. 5 is the entrance point and the silencer box front end connection diagram of Fan casing.
Embodiment: see Fig. 1-5, motor casing 8 is fixed in the Fan casing 7 by stator 6, elastic insert and link, motor casing 8 is provided with motor intake grill 11, and the entrance point of motor intake grill is positioned on the Fan casing, motor casing 8 inboard assembling noise elimination thermal-protective material 9 and perforated plates 10.Front end at motor casing 8 passes through supporting plate 15, coupling block and the affixed motor 14 of connecting bolt, constitute annular channel between perforated plate 10 and motor 14, the inboard affixed venting ring 13 of supporting plate 15 is a ventilated port in the middle of the venting ring 13, motor shaft passes venting ring 13, the affixed impeller 12 of its front end.On the casing header board 2 of Fan casing grafting platform 16 is set, the affixed inserting section 1 of the import front end of silencer box, the elasticity of the rubber material circle 15 that is flexible coupling is sleeved on the inserting section 1 of the grafting platform 16 of casing header board and silencer box.The rear end of Fan casing is connected with the outlet end of silencer box also adopts same spline structure.The outside of silencer box is the shell 3 of metal skin, and noise elimination thermal-protective material 4 and perforated plate 5 are equipped with in the inboard of shell 3.
Claims (1)
