Abstract
The utility model relates to a dust cleaning device for the leaf non-working face of the centrifugal fan. The technical proposal lies in that a pipe 7 is arranged at the entrance of the fan shell. A nozzle 3 is arranged at one end of the pipe 7. The outlet of the nozzle 3 points to the rear disk of an impeller 2. The other end of the pipe is connected with an external pipe 5. A four-way electromagnetic valve 4 is arranged at the joint of the external pipe 5 and the pipe 7. The four-way electromagnetic valve 4 is connected with a time relay 6. Therein, the nozzle 3 is arranged close to the rear disk of the impeller 2 and the installation angle is that the axis of the nozzle 3 forms an angle of 60 DEG to 70 DEG with the axis of the impeller 2. The medium of the external pipe 5 is water and the pressure is 0.3 MPa to 0.4 MPa. The set time of the time relay 6 is 1 to 5 minutes. The utility model has the characteristics of a fine effect of cleaning accumulated dust on the leaf non-working face, automatic control on the dust cleaning, a simple structure and a low cost.
Description
Technical field
The utility model belongs to the centrifugal blower fan blade wheel deashing device.Relate in particular to a kind of deashing device of blade non-working surface of centrifugal blower.
Background technique
Centrifugal blower is usually used in the bigger dust-containing airflow of dispatch water content, after its operation a period of time, body vibration will occur and strengthen, and is overhauled by forced-stopping machine.Its main cause is that air-flow can not directly wash away anterior generation of fan blade non-working surface, after the dust dried cake that accumulates in this, forms inhomogeneous coming off, and causes the impeller balance to be destroyed.The general ash-clearing technology of not shutting down is: inlet is provided with nozzle at blade; wish that the deashing medium is along the impeller radial motion; directly remove the dust stratification of blade non-working surface front portion, but owing to be subjected to the influence of factors such as pressure medium size, designs of nozzles, dust stratification can not be removed effectively.
Summary of the invention
Task of the present utility model provides a kind of dust stratification that can effectively remove the blade non-working surface, can control automatically, simple in structure, centrifugal blower fan blade wheel deashing device that cost is low.
For realizing above-mentioned task, the technological scheme that the utility model adopted is: be provided with pipeline in the ingress of centrifugal blower casing, an end of pipeline is equipped with nozzle, and the hub disk of impeller is pointed in the outlet of nozzle; The other end is connected with Outer Tube, in the joint of Outer Tube and pipeline four way solenoid valve is housed, and four way solenoid valve connects with the time relay.
Wherein: nozzle is installed near the hub disk of impeller; Setting angle is that the axis of nozzle and the axis of impeller are 60 °～70 °; The medium of Outer Tube 5 is a water, and pressure is 0.3MPa～0.4MPa; The setting value of the time relay 6 is 1～5 minute.
Deashing control links with the operation control of centrifugal blower, after centrifugal blower moves a period of time, and time relay work, four way solenoid valve is opened, and deashing begins; When the deashing time reached setting value, the time relay disconnected, and four way solenoid valve cuts out, and deashing finishes.
Owing to adopt technique scheme, the utlity model has that the dust stratification of removing the blade non-working surface is effective, deashing is controlled automatically, simple in structure, characteristics that cost is low.
Description of drawings

Fig. 2 is the plan view of Fig. 1.
Embodiment
The utility model will be further described below in conjunction with the drawings and specific embodiments.
Structure of the present utility model is provided with pipeline 7 in centrifugal blower casing 1 ingress as shown in Figure 1 and Figure 2, and an end of pipeline 7 is connected with external pipe 5, and the other end is connected with nozzle 3.The outlet of nozzle 3 is pointed to the hub disk of impeller 2 and is installed, and the setting angle of nozzle 3 is: the axis angle of the axis of nozzle 3 and impeller 2 is 60 °～70 °.In the Outer Tube 5 and the joint of pipeline 7 four way solenoid valve 4 is housed, four way solenoid valve 4 is connected with the time relay 6.
The medium of the Outer Tube 5 of present embodiment is a water, and pressure is 0.3MPa～0.4MPa.The setting value of the time relay 6 is 2～3 minutes.
After centrifugal blower moved a period of time, the time relay 6 was connected, and four way solenoid valve 4 is opened, and deashing begins; When the deashing time reached setting value, the time relay 6 disconnected, and four way solenoid valve 4 cuts out, and deashing finishes.
The utility model ash-removal effect is good, deashing is controlled automatically, simple in structure, cost is low.
