Fig. 1 is the first viewing angle constructions schematic diagram of centrifugal fan provided by the embodiment of the utility model;Fig. 2 is this reality With the second viewing angle constructions schematic diagram of the centrifugal fan that new embodiment provides.
As depicted in figs. 1 and 2, the utility model embodiment provides a kind of centrifugal fan, comprising: volute type body 1, Volute type body 1 is equipped with water inlet 11, water outlet 12 and exhaust outlet 13, is provided with impeller 2 in volute type body 1, closes on impeller 2 Blade exit at be provided with porous plate 3 in spiral case, be additionally provided in volute type body 1 in spiral case inlet pressure continuous poriferous plate 4 and Continuous poriferous plate 4 closes at exhaust outlet 13 and is arranged in spiral case inlet pressure;Sewage is entered in volute type body 1 by water inlet 11, in leaf Porous plate 3 is collided and is discharged by porous plate 3 in spiral case in blade and spiral case through impeller 2 under the high speed rotation effect of wheel 2, and again Secondary to collide with plate 4 continuous poriferous in spiral case inlet pressure, the hydrone and air after multiple high velocity impact in sewage are in a short time It is temporarily separated, while under the centrifugal pressure that 2 high speed rotation of impeller generates, the water and air after separation is drained through different directions And reach aqueous vapor separation.
Compared with the existing technology, centrifugal fan described in the utility model embodiment has the advantage that
Centrifugal fan provided by the embodiment of the utility model, as depicted in figs. 1 and 2, comprising: volute type body 1, snail Shell mould body 1 is equipped with water inlet 11, water outlet 12 and exhaust outlet 13, is provided with impeller 2 in volute type body 1, closes on impeller 2 It is provided with porous plate 3 in spiral case at blade exit, continuous poriferous plate 4 and snail in spiral case inlet pressure are additionally provided in volute type body 1 Continuous poriferous plate 4 closes at exhaust outlet 13 and is arranged in shell mould line;Sewage is entered in volute type body 1 by water inlet 11, in impeller 2 High speed rotation effect under in blade and spiral case through impeller 2 porous plate 3 collide and be discharged by porous plate 3 in spiral case, and again It is collided with plate 4 continuous poriferous in spiral case inlet pressure, the hydrone and air after multiple high velocity impact in sewage are temporary in a short time When separate, while under the centrifugal pressure that 2 high speed rotation of impeller generates, water and air after separation drain through different directions and Reach aqueous vapor separation.In conclusion centrifugal fan provided by the embodiment of the utility model, can either blending transportation again can The hydrone and air in sewage are separated, so as to effectively handle the smell in sewage.
Herein it should be added that, in centrifugal fan provided by the embodiment of the utility model, such as Fig. 1 and Fig. 2 Shown, when water and air after separation drains through different directions and reaches aqueous vapor separation, water is discharged by water outlet 12, air by Exhaust outlet 13 is discharged, to realize the purpose of aqueous vapor separation.
In addition, as shown in Fig. 2, in centrifugal fan provided by the embodiment of the utility model, porous plate 3 and snail in spiral case The shape harmony of lines of shell mould body 1.
Also, the effect of volute type body 1 is the gas guiding volute outlet that will leave impeller 2, and part dynamic pressure is turned Become static pressure.The structure of spiral case is complicated space curved surface body, and theoretically, the molded line of spiral case is helix, but due to helix Structure is more complex, it is difficult to manual drawing, therefore in production usually with simplified model come approximate.Wherein, volute type body 1 Molded line is not only directly related to the flow losses in spiral case, also has a significant impact to the aeroperformance of impeller 2, being capable of direct shadow Ring the performance parameters such as efficiency and output flow, the pressure of blower.
Fig. 3 is the first viewing angle constructions signal of impeller wheel portion in centrifugal fan provided by the embodiment of the utility model Figure;Fig. 4 is the second viewing angle constructions schematic diagram of impeller wheel portion in centrifugal fan provided by the embodiment of the utility model.
Wherein, as Figure 1-Figure 4, in centrifugal fan provided by the embodiment of the utility model, above-mentioned impeller 2 Blade shape can be backward tilt, i.e. the angle of outlet of the blade of impeller 2 can be effectively improved less than 90 degree using backward tilt blade The rotation efficiency of impeller 2;Also, the impeller 2 can connect motor 5, to be rotated simultaneously by 5 impeller 2 of motor Centrifugal force is generated, and then is temporarily separated the hydrone in sewage in a short time from air and passes through different directions in time (water is by water outlet 12, air by exhaust outlet 13) discharge.
It should be added that, when the angle of outlet of the blade of impeller 2 is greater than 90 degree, the form of blade is to lean forward herein Formula.Since when from blower size and revolving speed all, the angle of outlet is bigger, and the pressure of generation is higher, therefore forward tilt and hypsokinesis The advantage that formula is compared is that total head pressure is bigger.But the specific gravity that forward tilt blower dynamic head accounts for total head pressure is also bigger, and air velocity is high, Loss when being converted into static pressure is also just bigger, thus the height that efficiency does not have backward tilt.
