Abstract
The utility model relates to blower fan technical field, relate in particular to a kind of fan casing structure with bypass type pipeline, it comprises housing, bypass line, on described housing, be provided with air sucking mouth and exhaust outlet, air sucking mouth side and the exhaust outlet side of described housing are connected with bypass line, described bypass line down vertically extends from air sucking mouth, behind turning, extend and be connected with exhaust outlet in the horizontal direction, at the air sucking mouth of housing of blower fan and the exhaust outlet of housing, follow according to the size of air quantity and the capacity of reflux of pipeline and design one with the bypass line of modulating valve, according to the capacity of reflux design in pipeline, avoid the surge area of blower fan, on the basis that does not increase too many fabricating cost, solved so the large adjusting of blower fan than the surge difficulty of bringing, reached same good using effect.
Description
[technical field]
The utility model relates to blower fan technical field, relates in particular to a kind of fan casing structure with bypass type pipeline.
[background technique]
Along with smelting furnace in non-ferrous metal industry, holding furnace, the purge using in the bodies of heater such as oven or burning-assist centrifugal blower, the effect of this type of blower fan is with different air quantity after the burner in a burner, blast is adjusted rigidity and the degree of flexibility of flame, change due to material technology technique making in body of heater, the adjusting ratio that the applying working condition of burner is also proposed to 1: 10 requires, so the airflow pressure of blower fan is used regional extent just broad than general blower fan, and within the scope of this, just in time there is a surge area of blower fan self, the now vibration of blower fan, noise is all very large, have a strong impact on the working life of blower fan.General centrifugal blower, greatly reduces the working life of blower fan, and after casing side adds a bypass, just can solve and avoid surge area than using and be prone to surging phenomenon in situation in this large adjusting, makes blower fan smooth running.
Therefore, in order to overcome the deficiency of above-mentioned technology, to design a fan life long, and stability in use is a kind of fan casing structure with bypass type pipeline, just inventor's problem to be solved better.
[model utility content]
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of fan casing structure with bypass type pipeline, and fan life is long, and stability in use is better.
For achieving the above object, the utility model can adopt following technological scheme: a kind of fan casing structure with bypass type pipeline, it comprises housing, bypass line, on described housing, be provided with air sucking mouth and exhaust outlet, air sucking mouth side and the exhaust outlet side of described housing are connected with bypass line, described bypass line down vertically extends from air sucking mouth, behind turning, extends and is connected with exhaust outlet in the horizontal direction.
Further, described bypass line comprises several bypass tubes, modulating valve, between described bypass tube, by flange, connects, and is provided with modulating valve between bypass tube.
Further, described housing both sides are enclosed with thermal insulation layer, and the bypass line that described housing is connected with a side of bypass line passes thermal insulation layer.
Further, described bypass line and air sucking mouth adopt be threaded or weld in any one.
Further, between described bypass line and exhaust outlet, adopt and be welded to connect.
Compared with prior art, the beneficial effects of the utility model are: at the air sucking mouth of housing of blower fan and the exhaust outlet of housing, follow according to the size of air quantity and the capacity of reflux of pipeline and design one with the bypass line of modulating valve, according to the capacity of reflux design in pipeline, avoid the surge area of blower fan, on the basis that does not increase too many fabricating cost, solve so the large adjusting of blower fan than the surge difficulty of bringing, reached same good using effect.

Description of reference numerals: 1-housing; 2-bypass line; 3-thermal insulation layer; 4-bypass tube; 5-modulating valve; 6-air sucking mouth.
[embodiment]
Below in conjunction with specific embodiment, further set forth the utility model, should be understood that these embodiments are only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model instruction, these equivalent form of values drop on application appended claims limited range equally.
Shown in Figure 1, a kind of fan casing structural representation with bypass type pipeline of the utility model, fan casing structure comprises housing 1 and bypass line 2, on described housing 1, be provided with air sucking mouth and exhaust outlet, air sucking mouth side and the exhaust outlet side of housing 1 are connected with bypass line 2, described bypass line 2 down vertically extends from air sucking mouth, behind turning, extends and is connected with exhaust outlet in the horizontal direction.
Shown in Figure 2 is bypass line sectional drawing in the utility model Fig. 1, and described bypass line 2 comprises several bypass tubes 4, modulating valve 5, between described bypass tube 4, by flange, connects, and is provided with modulating valve 5 between bypass tube 4.Housing 1 both sides are enclosed with thermal insulation layer 3, and the bypass line 2 that described housing 1 is connected with a side of bypass line 2 passes thermal insulation layer 3.Bypass line 2 adopts and is threaded or welds with air sucking mouth, between bypass line 2 and exhaust outlet, adopts and is welded to connect.
The utility model is waited in use, can regulate by modulating valve 5 size of air quantity in bypass line 2, and then the size of the inner air quantity of adjusting blower fan, at the air sucking mouth of housing 1 of blower fan and the exhaust outlet of housing 1, follow according to the size of air quantity and the capacity of reflux of pipeline and design one with the bypass line 2 of modulating valve 5, according to the capacity of reflux design in pipeline, avoid the surge area of blower fan, on the basis that does not increase too many fabricating cost, solve so the large adjusting of blower fan than the surge difficulty of bringing, reached same good using effect.
