Description
Technical field:
The utility model relates to a kind of centrifugal blower, particularly a kind of centrifugal blower that blast air and cooling-air separately can be filtered.
Background technique:
Existing centrifugal blower comprises rack 1 and is installed on the main frame 2 in rack 1.Wherein main frame 2 is as the core component in centrifugal blower, it comprises host shell 20, be installed on the spiral case 21 on host shell 20, be installed on intake duct 22 that is on spiral case 21 and that connect with spiral case 21 inner chamber, be installed on blast air outlet pipe 26 that is on spiral case 21 and that connect with spiral case 21 inner chamber, be arranged at rotor 23 in host shell 20 and the bearing be installed on rotor 23 and motor, the right end of its rotor 23 extends beyond outside host shell 20 until in spiral case 21 inner chamber, the right end of rotor 23 is provided with impeller 24, the left-end point of rotor 23 is provided with cooling fan 25, position near cooling fan 25 on the left-end point of host shell 20 is provided with cooling-air outlet pipe 27, wherein the air outlet of cooling-air outlet pipe 27 is positioned at the outside of rack, side relative with intake duct 22 on rack 1 is provided with air inlet 10, air inlet 10 place is provided with and air is carried out filtered air filter 11.
In said structure, the effect of impeller 24 is: air is sucked from intake duct 22, is bloated from blast air outlet pipe 26 by spiral case 21, realizes outside air blast; The effect of cooling fan 25 is: the inlet hole that air is arranged from host shell 20 is sucked, and makes it flow through host shell inside and discharge from cooling-air outlet pipe 27, thus plays the effect of cooled rotor, bearing and motor.
As shown in Figure 1, the air after air filter 11 process on machine cabinet door plate is all come from due to blast air and cooling-air, so the problem of a contradiction can be caused: if select high efficiency particulate air filter, can ensure that the cooling-air flowing into host shell inside is very clean, but because the ventilation of high efficiency particulate air filter is little, cannot ensure the air quantity (i.e. the air-blowing quantity not sufficient of blower fan) that impeller 24 works required, and consider cost, it is also a kind of waste that impeller 24 sucks so clean air; And if select poor efficiency or medium efficient filter, the air quantity (namely the air-blowing amount of blower fan is up to standard) needed for impeller work can be ensured, but this contains a large amount of dust by causing the cooling-air entering host shell inside, through the operation in one period, host shell inside is greasy dirt entirely, can affect the heat radiation of parts, electric wire insulation, also can affect the suspension characteristic of bearing, the serious rotor that will cause cannot suspend and rotate.
Therefore, necessary the deficiency solving prior art is improved to prior art.
