Abstract
The utility model relates to a filtering centrifugal fan, which comprises a base, a motor, an impeller and a volute. The impeller positioned inside the volute is mounted on a shaft of the motor, and an air inlet and an air outlet are arranged on the volute. The fan is characterized in that a soundproof layer is disposed on the periphery of the volute, an air inlet guiding pipe and an air outlet guiding pipe are arranged on the soundproof layer at a corresponding position relative to the air inlet and the air outlet, and simultaneously an air filtering component is disposed at a position of the air inlet, thereby the fan avoids the drawback of overlarge noise in the running operation of a conventional centrifugal fan, simultaneously increases the process of filtering air, and effectively prevents security accident of operation troubles of the centrifugal fan caused by dusts.
Description
Technical field
The utility model relates to a kind of centrifugal blower, relates in particular to a kind of filtering type centrifugal blower.
Background technique
As everyone knows, centrifugal blower generally comprises following main member: a housing, and it has the spirality air channel, is referred to as collector ring, is provided with outlet in its end, is provided with inlet or eyelet at described collector ring center; One draught fan impeller, it is arranged on described collector ring eyelet downstream and drives the hub draw up and be connected with being linked at; And a plate washer or a diffuser, it is arranged on described draught fan impeller downstream.
In centrifugal blower, the air-flow body of air or other processing through inlet with the direction of shaft parallel by the draught fan impeller suction, and carry by draught fan impeller with direction perpendicular to rotating shaft.The air communication of being carried by draught fan impeller is crossed that baffle plate turns to or is further handled by diffuser entering the air-flow set and before guiding the collector ring of outlet into.Centrifugal blower can be the type with single or two suction ports, and promptly they only suck air from draught fan impeller one side or from its two opposite sides.
Draught fan impeller is formed by vaned roulette wheel, and it is made up of at the diskware of their base portions vanes fixed.Just have the blower fan of single suction port, blade only is arranged on a side of this diskware, and about having the blower fan of two suction ports, blade then is arranged on the both sides of this diskware.
But noise is excessive in the existing centrifugal blower running, lacks airfiltering process simultaneously, causes air quality to improve.The more important thing is,, cause dust to influence the operation of centrifugal blower, strengthened probability of failure owing to lack strobe utility.Simultaneously, also the equipment room ventilation that adopts centrifugal blower is required to have constituted influence.
Summary of the invention
The purpose of this utility model is to overcome the above problem that prior art exists, and a kind of filtering type centrifugal blower is provided.
For realizing the purpose of this utility model filtering type centrifugal blower, comprise base, motor, impeller and spiral case, impeller is positioned at spiral case, be installed on the motor shaft, spiral case is provided with intake grill and exhaust outlet, wherein: described spiral case periphery is provided with puigging, and the corresponding position of puigging relative intake grill place and exhaust outlet is provided with air intake leading pipe and air-out leading pipe, is provided with air filtering assembly at the intake grill place simultaneously.
Further, above-mentioned filtering type centrifugal blower, wherein, the two ends of described air filtering assembly contact with the spiral case inwall.
Further, above-mentioned filtering type centrifugal blower, wherein, described air filtering assembly comprises air drying layer and dust filter screen, and the dust filter screen is positioned at the end of air intake leading pipe, and the rear side of dust filter screen is interval with the air drying layer.
Further, above-mentioned filtering type centrifugal blower, wherein, described dust filter screen is a cloth bag type.
Again further, above-mentioned filtering type centrifugal blower wherein, is provided with auxiliary fixing plate between described spiral case outer wall and the puigging inwall.
Adopt technical solutions of the utility model, exempted from the past the excessive defective of noise in the centrifugal blower running.Increased airfiltering process simultaneously, effectively prevented security incident because of the caused centrifugal blower operation troubles of dust.
The purpose of this utility model, advantage and characteristics will illustrate by following preferential embodiment's non-limitative illustration and explain that these embodiments only provide as an example with reference to accompanying drawing.
Description of drawings
Fig. 1 is the organigram of filtering type centrifugal blower.
The implication of each reference character is as follows among the figure:
1 impeller, 2 puiggings
3 air intake leading pipes, 4 air-out leading pipes
5 spiral cases, 6 air drying layers
7 dust filter screens, 8 auxiliary fixing plates
Embodiment
Filtering type centrifugal blower as shown in Figure 1, comprise base, motor, impeller 1 and spiral case 5, impeller 1 is positioned at spiral case 5, be installed on the motor shaft, spiral case 5 is provided with intake grill and exhaust outlet, its specialization is: described spiral case 5 peripheries are provided with puigging 2, and the corresponding position of puigging 2 relative intake grill places and exhaust outlet is provided with air intake leading pipe 3 and air-out leading pipe 4, are provided with air filtering assembly at the intake grill place simultaneously.
Further, for air being carried out exhaustively comprehensive filtration, the two ends of air filtering assembly contact with spiral case 5 inwalls, help forming the confined space of filtration.
In conjunction with the utility model one preferred implementation, air filtering assembly comprises air drying layer 6 and dust filter screen 7, and dust filter screen 7 is positioned at the end of air intake leading pipe 3, and the rear side of dust filter screen 7 is interval with air drying layer 6.And for the ease of the replacement of dust filtration and dust filter screen, through after the multiple comparison test, dust filter screen 7 is preferable with cloth bag type.
Simultaneously, consider that the vibrations that produce after motor, impeller 1 running can cause the generation of noise.Therefore, between spiral case 5 outer walls and puigging 2 inwalls, be provided with auxiliary fixing plate 8, reduce vibrations, the further auxiliary generation that reduces noise with this.
Moreover, in order to satisfy the light degree of filtering type centrifugal blower, also not reducing its firm degree simultaneously, spiral case 5 is made for unsaturated polyester resin and glass fibre.
After the centrifugal blower running, 1 running of driven by motor impeller produces blast.Subsequently, air imports by intake grill.During this period, the air of introducing at first passes through effective filtration of cloth bag type dust filter screen 7, removes dust and magazine.And then, by the effect of air drying layer 6, the airborne steam of filtering reaches the needed degree of drying of machine room work.And, in whole operation process, depend on the existence of puigging 2, there is not intrinsic noise disadvantage during centrifugal blower work.
By above-mentioned character express and in conjunction with the accompanying drawings as can be seen, adopt the utility model after, avoided in the past the excessive defective of noise in the centrifugal blower running.Increased airfiltering process simultaneously, effectively prevented security incident because of the caused centrifugal blower operation troubles of dust.
Certainly, more than only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.In addition to the implementation, the utility model can also have other mode of execution.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop within the utility model scope required for protection.
