Description

A kind of centrifugal blower
Technical field
The utility model relates to field of ventilation equipment, particularly relates to a kind of centrifugal blower.
Background technique
Centrifugal blower is the mechanical energy relying on input, and improve gas pressure and to supply gas side by side the machinery of body, it is a kind of driven fluid machinery.Centrifugal blower is widely used in factory, mine, tunnel, cooling tower, vehicle, the ventilation of boats and ships and building, dust discharge and cooling; The ventilation of boiler and industrial furnace and air inducing; Cooling in the apparatus of air conditioning and domestic electric appliance and ventilation; The oven dry of cereal and selecting and recommending; The inflation of wind-tunnel wind regime and Hovercraft and propelling etc.Centrifugal fan is made up of casing, main shaft, impeller, bearing transmission mechanism and motor etc.; casing there are intake grill and exhaust outlet; in the occasion that some dust are more, intake grill can be gathered on impeller after sucking dust; cause damage even to accumulate after electrostatic to equipment and blast; threaten personal safety, air inlet is usually open simultaneously, does not have protective measure; workman may be caused not stretch in intake grill, the situation of harm personal safety.
Model utility content
The utility model provides a kind of centrifugal blower, is provided with dust hood and containment vessel in air inlet, and in order to solve technique scheme, the utility model adopts following technological scheme:
A kind of centrifugal blower, comprise spiral case, described spiral case is provided with intake grill and exhaust outlet, described intake grill is arranged on the side of spiral case, described spiral case opposite side is fixedly connected with supporting base, support is provided with below described supporting base, described support is provided with motor, impeller is provided with in described spiral case, described impeller is connected with motor by belt wheel, it is characterized in that, described air inlet is connected with dust hood, described dust hood is externally connected with containment vessel, described dust hood is hollow cylindrical, described dust hood week is as fine and closely woven mesh, spongy layer is provided with in described mesh, described containment vessel is in the form of annular discs, and described containment vessel has multiple intake opening.
A kind of centrifugal blower that the utility model provides, preferably, described dust hood is bolted on intake grill.
A kind of centrifugal blower that the utility model provides, preferably, described containment vessel is connected with dust hood by hinge.
A kind of centrifugal blower that the utility model provides, preferably, described frame is made up of with crossbeam side plate, and described side plate is all shaped steel with crossbeam.
Advantage of the present utility model and beneficial effect are: the ventilator that the utility model provides, compact structure, performance curve is smooth, dust hood and containment vessel has been added in air inlet, utilize dust-proof cover can dust effectively in filtered air, prevent dust from overstocking in impeller, even under the effect of electrostatic, produce blast, substantially increase the Security of ventilator; Meanwhile, utilize containment vessel, the situation of false touch can be prevented, stop unexpected generation, protect personal safety.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, preferred implementation of the present utility model is preferably described, wherein,
Fig. 1 is the schematic diagram of a kind of centrifugal blower of the utility model;
Fig. 2 is the side view of a kind of centrifugal blower of the utility model.
Embodiment
With reference to Fig. 1--the embodiment of 2 pairs of a kind of centrifugal blowers of the utility model is described further:
A kind of centrifugal blower, comprise spiral case 1, described spiral case 1 is provided with intake grill 2 and exhaust outlet 3, described intake grill 2 is arranged on the side of spiral case 1, described spiral case 1 opposite side is fixedly connected with supporting base 9, support 4 is provided with below described supporting base 9, described support 4 is provided with motor 5, impeller is provided with in described spiral case 1, described impeller is connected with motor 5 by belt wheel 8, it is characterized in that, described intake grill 2 place is connected with dust hood 6, described dust hood 6 is externally connected with containment vessel 7, described dust hood 6 is in hollow cylindrical, described dust hood 6 weeks is as fine and closely woven mesh, spongy layer is provided with in described mesh, described containment vessel 7 is in the form of annular discs, and described containment vessel 7 has multiple intake opening 71.
Preferably, described dust hood 6 is bolted on intake grill 2, the mesh on described dust hood 6 whole body assumes diamond in shape shape, distribute comparatively fine and closely woven, effectively prevent oarse-grained impurity from entering, in mesh, be also provided with spongy layer, further air filtered, ensure the quality of the air entered in impeller.
Simultaneously; described containment vessel 7 is connected with dust hood 6 by hinge; this containment vessel 7 is made up of stainless steel, and long service life, during use; containment vessel 7 is covered dust hood 6; containment vessel 7 has intake opening 71, described frame 7 is made up of with crossbeam side plate, and described side plate is all shaped steel with crossbeam; compact structure, load-bearing property is good.
Last it is noted that the foregoing is only preferred embodiment of the present utility model; be not limited to the utility model; although be described in detail the utility model with reference to previous embodiment; for a person skilled in the art; it still can be modified to the technological scheme described in foregoing embodiments; or equivalent replacement is carried out to wherein portion of techniques feature; all within spirit of the present utility model and principle; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
