Abstract
The utility model belongs to the technical field of ventilating products, and particularly discloses a centrifugal fan with double air outlets. The centrifugal fan comprises a volute casing and an impeller placed in the volute casing, the volute casing is provided with an air inlet and the air outlets, the symmetrical double air outlets with the same air flow directions are disposed on the volute casing, and the exterior line of the volute casing is a logarithmic spiral. The centrifugal fan with the double air outlets can realize balanced ventilation to two different directions simultaneously, omits additionally connecting elbows, can reduce installation of the elbows and decreases resistance of an air pipe system. In addition, compared with a centrifugal fan with a single air outlet, the centrifugal fan with the double air outlets is large in air volume, high in pressure and efficiency, simple in manufacturing process and low in manufacturing cost.
Description
Technical field
The utility model belongs to the ventilator technical field, is specifically related to a kind of pair of exhaust outlet centrifugal blower.
Background technique
In the prior art, common centrifugal blower all only is provided with an exhaust outlet on its spiral case, needs a typhoon machine like this when different both direction balanced ventilation, needs external elbow could realize the purpose of blowing to different direction.But owing to be equipped with outer tube joint, the fabricating cost of product is increased, structure complicated, and also it has increased the air-line system internal resistance widely, makes air quantity little, and efficient is low, the air-supply weak effect.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, and the centrifugal blower of a kind of pair of exhaust outlet is provided.This centrifugal blower can reach a typhoon machine simultaneously to two different direction connecting tubes when air-supply.This centrifugal blower is bigger than the centrifugal blower air quantity of single exhaust outlet, and pressure is big, the efficient height, and preparation process is simple, and fabricating cost is cheap.
In order to realize above-mentioned technical purpose, the utility model is realized by following technological scheme:
A kind of pair of exhaust outlet centrifugal blower described in the utility modelly, comprise spiral case and place the interior impeller of spiral case, described spiral case is provided with intake grill and exhaust outlet, and described spiral case is provided with the identical and symmetrical two exhaust outlets of airflow direction, and the outer molded lines of described spiral case is a log spiral.
In the utility model, described spiral case is equilateral basic logarithmic spiral spiral case or inequilateral base logarithmic spiral spiral case.
Further improve as above-mentioned technology ground, the forward and backward side correspondence of described spiral case is provided with front side plate and back side panel, and the front side plate on the described spiral case and back side panel are square.
In the utility model, described intake grill is the awl arcuate structure.
In the utility model, the front side plate of described spiral case is provided with a circular inner hole that cooperates with the intake grill external diameter.
In addition, in the utility model, the back side panel of described spiral case is provided with a circular port that cooperates with impeller outer diameter, and described spiral case back side panel is provided with the framework that motor is installed.
In the utility model, described impeller is antecurvature multiple-airfoil type impeller or backswept impeller.
Compared with prior art, the beneficial effects of the utility model are:
(1) described in the utility model pair of exhaust outlet centrifugal blower is owing to be provided with the identical and symmetrical two exhaust outlets of airflow direction on spiral case, it can realize that a typhoon machine is simultaneously to two different direction balanced ventilations, and need not other adjunction elbow, can reduce and elbow is installed and be reduced the air-line system resistance, effectively improve air-supply efficient, and it is effective to blow.
(2) the utility model disposes antecurvature multiple-airfoil type impeller and backswept impeller and the contrast of single exhaust outlet blower fan, and under identical configuration power of motor and identical air quantity situation, total head increases by 20%.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in detail:
Fig. 1 is a described in the utility model pair of exhaust outlet centrifugal blower Facad structure schematic representation;
Fig. 2 is the right side view of above-mentioned Fig. 1;
Embodiment
As shown in Figure 1 and Figure 2, a kind of pair of exhaust outlet centrifugal blower described in the utility model, comprise spiral case 2 that has front side plate 6 and back side panel 8 and the impeller 9 that places in the spiral case 2, the outer molded lines of described spiral case 2 is a log spiral, this log spiral type spiral case 2 can be equilateral basic logarithmic spiral spiral case, also can be inequilateral base logarithmic spiral spiral case.Described spiral case 2 is provided with intake grill 7 and the identical and symmetrical two exhaust outlets 1,5 of airflow direction, and this pair exhaust outlet 1,5 is located at 180 ° and 0 ° of position of spiral case 2 respectively.
As shown in Figure 2, the forward and backward side of described spiral case 2 is respectively equipped with square front side plate 6 and back side panel 8, and the front side plate 6 of described spiral case 2 is provided with a circular inner hole 20 that cooperates with intake grill 7 external diameters, and described intake grill 7 is the awl arcuate structure.Described spiral case back side panel 8 is provided with a circular port 30 that cooperates with impeller 9 external diameters.Described back side panel 8 is provided with the motor scaffold 4 of an installation motor 10.
The installation process of the two exhaust outlet centrifugal blowers in ground described in the utility model is as follows:
(1) motor 10 is installed on the motor scaffold 4, impeller 9 is installed on the motor 10, more circular back shroud 3 is installed on the back side panel 8 of spiral case 2; Circular back shroud 3 with impeller 9 is installed into spiral case 2 after the back side panel 8 of spiral case 2 is connected.
(2) intake grill 7 is installed on the front side plate 6 cooperated with impeller 9.Motor 10 running impeller 9 suck gas behind impeller 9 diffusions from intake grill 7, discharge gas from two exhaust outlets 1,5 of spiral case 2 respectively, thereby realize the whole service process of blower fan.
The utility model is not limited to above-mentioned mode of execution, if various changes of the present utility model or modification are not broken away from spirit and scope of the present utility model, if these are changed and modification belongs within claim of the present utility model and the equivalent technologies scope, then the utility model also comprises these changes and modification.
