Abstract
The utility model discloses a novel centrifugal blower structure of an iron melting furnace, which comprises a chassis, a base and a transmission group arranged on the base. The chassis is provided with an air outlet facing the iron melting furnace, one end of the transmission group is connected with a driving mechanism through a toothed V-shaped belt, and the other end of the transmission group is connected with an impeller; and the impeller is arranged in the chassis formed by welding of steel plates, and a diffuser and an air intake cover plate are arranged between the impeller and the air outlet. In the utility model, since the welded chassis is adopted instead of a cast chassis, the weight of a blower can be reduced. Meanwhile, the surfaces of the steel plates adopted by the welded chassis are smoother, losses of wind energy can be reduced, and noise can also be reduced. In addition, since the high-strength toothed V-shaped belt is adopted in the improvement, the number of the toothed V-shaped belts actually used in the blower can be reduced, the radial torque born by the bearing of the transmission group can also be reduced, and the service life of the bearing can be prolonged.
Description
Technical field
The utility model relates to a kind of blower fan structure, relates in particular to a kind of novel cupola furnace centrifugal blower structure.
Background technique
The cupola furnace blower also is cupola blower, because of gaining the name on the stove that is used in the melting molten iron.
The cupola furnace blower can be divided into single-stage, twin-stage, three grades of cupola furnace blowers.Casing is the cast iron casing, can improve the rigidity of blower fan, and can prevent vibrations and absorb noise.
Wherein, its flow of single-stage cupola furnace is little, pressure is high, rotating speed is high, generally is used on the cupola of 1-7 ton, adopts the belt pulley speedup.And the coupling direct connection is adopted in the twin-stage cupola furnace, and rotating speed is low, pressure is high, stable, generally is used on the big cupola, and is more common on the cupola of 5-20 ton.The coupling direct connection is also adopted in three grades of cupola furnace, is on the basis of secondary, to develop, and has economize on electricity more and reduces noise two big outstanding features, has that volume is little, in light weight, pressure is high, uses characteristics such as easy to maintenance, the difficult overload of motor.
Yet for the single-stage cupola furnace, the interior runner of its cast iron structure is uneven, makes the wind energy loss increase; Moreover this class formation has also caused the noise in using higher; Simultaneously, owing to be to use many common vee belts to carry out transmission, make that also the radially moment that bearing bore of transmission group is bigger, thereby influenced the working life of bearing.
The model utility content
The utility model is to the drawback of existing technology, and a kind of novel cupola furnace centrifugal blower mechanism is provided.
The described novel cupola furnace of the utility model centrifugal blower structure; Comprise casing, base and be arranged at the transmission group of base; Said casing is provided with the exhaust outlet towards the cupola furnace, and an end of said transmission group connects driving mechanism through band tooth V-type band, and the other end then is connected with impeller;
Said impeller is set in the casing that is welded by steel plate, between impeller and exhaust outlet, also is provided with Diffuser and air intake cover plate.
In the centrifugal blower structure of the described novel cupola furnace of the utility model; Adopt the welding type shell and abandon the founding type casing, not only can alleviate the weight of blower, simultaneously; Because the surface of steel plate that the welding type shell adopts is Paint Gloss, also make the loss minimizing of wind energy, noise reduce; In addition, use high-intensity band tooth V-type band, can reduce the quantity of the band tooth V-type band of the actual use of blower, thereby the radially moment that bearing bore of transmission group also is reduced, improved the working life of bearing through improving.
Description of drawings
Fig. 1 is the schematic representation of the said novel cupola furnace of the utility model centrifugal blower structure.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed description, can implement according to this with reference to the specification literal to make those skilled in the art.
As shown in Figure 1, the described novel cupola furnace of the utility model centrifugal blower structure comprises casing 1, base 7 and is arranged at the transmission group 5 of base 7.
Wherein, said casing 1 is welded by the polylith steel plate, and this casing 1 is provided with the exhaust outlet 8 towards the cupola furnace.In the utility model, casing adopts welding type and has abandoned traditional founding type, not only can alleviate the weight of blower; Simultaneously, because the surface of steel plate that the casing 1 of welding type adopts is Paint Gloss, also make loss minimizing, the noise of wind energy also be lowered.
End at said transmission group 5 is provided with band tooth V-type band 6; This band tooth V-type band 6 can adopt high tenacity band tooth narrow V belt; Connect driving mechanism through this high tenacity band tooth narrow V belt; Rotate to make this external driving mechanism can drive transmission group 5, and then the impeller 4 that makes transmission group 5 the other ends connect rotates.Use the narrow V-type band of high-intensity band tooth through improving, can reduce the quantity of the narrow V-type band of band tooth of the actual use of blower, this makes that the radially moment that bearing bore of transmission group 5 is reduced greatly, and is improved the working life of bearing.For example, be to use 6～8 vee belts in the existing technology, then used 3～4 narrow V-type bands of high-intensity band tooth in the utility model.Moreover, use the narrow V-type band of high tenacity band tooth in the utility model, also make the limit speed of blower raise, and temperature is by using 96 ℃ of common vee belt to be reduced to 42 ℃.
Said impeller 4 is set in the casing 1, and this impeller 4 is connected for the running-on formula with exhaust outlet 8, and this structure helps reducing the air quantity internal leakage, to improve the efficient of blower.
Between the exhaust outlet 8 of impeller 4 and casing 1, also be provided with Diffuser 3 and air intake cover plate 2.Wherein, said Diffuser 3 is improved the gas-static that passes through; Air intake cover plate 2 then comprehensively is provided with built-in rectifier, makes the air whirl district " by capturing " that gets in the housing, can prevent eddy current loss, improves and boosts and flow efficiency.
Although the embodiment of the utility model is open as above; But it is not restricted to listed utilization in specification and the mode of execution; It can be applied to the field of various suitable the utility model fully, for being familiar with those skilled in the art, can easily realize other modification; Therefore under the universal that does not deviate from claim and equivalency range and limited, the legend that the utility model is not limited to specific details and illustrates here and describe.
