Abstract
The utility model belongs to the field of centrifugal fans, in particular to an airflow blowing device. The airflow blowing device comprises an air collector and an intake pipeline, wherein the air collector is arranged at the air outlet of a fan, the air collector is connected with one end of the intake pipeline, the intake pipeline penetrates out of the side wall of an enclosure and extends into the interior of an impeller via the air inlet of the fan, a nozzle is arranged at the other end of the intake pipeline, the nozzle is positioned at the inner side of the impeller, and an airflow control valve is arranged on the intake pipeline. The airflow blowing device can clean the impeller of the fan by utilizing the airflow generated by the fan in normal operating state, and forms strong airflow through the nozzle, so that dust is enabled to be in suspension state and cannot stay on blades, no dust is accommodated on the blades, the blades are accordingly enable to keep balance, and cannot generate vibration.
Description
Technical field
The utility model relates to a kind of gas flow purging device, relates in particular to the centrifugal blower field.
Background technique
At present, any centrifugal blower, under situation about running well, the time one is long, and the just easy dust of impeller blade non-working surface will be hung one deck ash on the blade in the course of time, because the thickness difference of dust makes the impeller disequilibrium produce vibration on the blade.
Summary of the invention
According to above deficiency of the prior art; The technical problem that the utility model will solve is: provide a kind of simple in structure, can the automated cleaning blower fan on the gas flow purging device of impeller blade dust, thereby solve because of the different bladed disk vibration problems that produce of blade dust thickness.
The utility model solves the technological scheme that its technical problem adopted: a kind of gas flow purging device; It is characterized in that: comprise wind collecting unit and intake line, wind collecting unit is arranged on the exhaust outlet place of blower fan, and wind collecting unit connects an end of intake line; Intake line passes and stretches into impeller inside from the intake grill of blower fan from the sidewall of casing; The other end of intake line is provided with nozzle, and nozzle is positioned at the impeller inboard, and control damper is set on the intake line.
Described nozzle can be provided with one group or two groups.Only need on intake line, to adorn one group of nozzle in the little blower fan and get final product, and the angle that need adorn in the blower fan greatly between two groups of nozzles and the two groups of nozzles is 85 ° ± 5 °, thereby can well clean blade.In order to prevent that nozzle and blade from touching and guaranteeing to purge effect, nozzle-end is 15mm apart from the blade closest approach.
Working principle and process:
The pressure that itself produces when utilizing blower fan to run well, by wind collecting unit with in a part of air-flow inspiration intake line, and through control damper control air-flow size; Utilize nozzle to form air blast then, the moving all blades of impeller revolution are purged one time successively, and making dust be state of suspension can not retain on blade; Discharge by exhaust outlet then; Do not have the dust of accumulation on the blade, thereby make impeller keep balance, should not produce vibration.
The beneficial effect that the utility model had is:
This gas flow purging device, the air-flow that itself produces in the time of can utilizing blower fan to run well cleans draught fan impeller, and forms air blast through nozzle; Making dust be state of suspension can not retain on blade; Free from dust stockpiles on the blade, thereby makes impeller keep balance, should not produce vibration.

Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done and to further describe:
Shown in Fig. 1～3; The gas flow purging device comprises wind collecting unit 6 and intake line 4, and wind collecting unit 6 is arranged on exhaust outlet 7 places of blower fan, and wind collecting unit 6 connects an end of intake line 4; Intake line 4 passes and stretches into impeller 1 inside from the intake grill 3 of blower fan from the sidewall of casing 8; The other end of intake line 4 is provided with nozzle 2, and nozzle 2 is positioned at impeller 1 inboard, and control damper 5 is set on the intake line 4.Described nozzle 2 can be provided with one group or two groups.Only need on intake line 4, to adorn one group of nozzle 2 in the little blower fan and get final product, and the angle that need adorn in the blower fan greatly between two groups of nozzles 2 and the two groups of nozzles 2 is 85 ° ± 5 °, thereby can well clean blade.
Working principle and process:
The pressure that itself produces when utilizing blower fan to run well, by wind collecting unit 6 with in a part of air-flow inspiration intake line 4, and through control damper 5 control air-flows sizes; Utilize nozzle 2 to form air blast then, the moving all blades of impeller 1 revolution are purged one time successively, and making dust be state of suspension can not retain on blade; Discharge by exhaust outlet 7 then; Do not have the dust of accumulation on the blade, thereby make impeller 1 keep balance, should not produce vibration.
