Description
Technical field
Boiler ventilation apparatus field is the utility model is related to, in particular a kind of primary air fan entrance dust-proof mechanism.
Background technology
, it is necessary to which blower fan long-time air feed into burner hearth, due to being influenceed by boiler slag removal operation, boiler is attached during boiler operation
Particulate pollutant is more near air, these pollutants enter blower fan especially primary air fan when inevitably in blower fan
Portion is progressively built up, and causes blower fan work abnormal, influences the service life of blower fan, influences the normal work of boiler indirectly；And contain
The more air of particulate matter enters boiler internal also can form influence to the combustion rate of burner, further influence the heat energy of boiler
Utilization rate.
The content of the invention
The utility model purpose is to solve the above problems, there is provided a kind of primary air fan entrance dust-proof mechanism, specifically by
Following technical scheme is realized：
Primary air fan entrance dust-proof mechanism, including the first air inlet pipeline, the second air inlet pipeline, air duct, some screen packs
And reversing plate, first air inlet pipeline, the second air inlet pipeline are connected to one end of the air duct, and described first enters
Air pipe line, the tube wall of the second air inlet pipeline are crossed to form crosspoint, and the reversing plate is articulated with the crosspoint and is located at air duct
Internal side, and the shape of the reversing plate is consistent with the inner section of first air inlet pipeline, the second air inlet pipeline,
Rotating shaft and external motor drive connection of the reversing plate in hinged place, connect described first when being rotated so as to the reversing plate and enter
Air pipe line and the air duct connect second air inlet pipeline and the air duct；First air inlet pipeline, second
The middle part tube wall of air inlet pipeline is respectively arranged with some inserting grooves, and some screen packs are plugged in the inserting groove；It is described
The other end of air duct docks with the air inlet of the primary air fan.
Described primary air fan entrance dust-proof mechanism, further design is for it, first air inlet pipeline, the second air intake
The middle part of pipeline is connected by the first backflushing pipe, the second backflushing pipe via the side wall of the air duct with the air duct respectively
It is logical；The first recoil blower fan, the first magnetic valve are serially connected with the middle part of first backflushing pipe；The middle part of second backflushing pipe
It is serially connected with the second recoil blower fan, second solenoid valve.
Described primary air fan entrance dust-proof mechanism, further design is for it, first air inlet pipeline, the second air intake
The entrance top of pipeline is respectively arranged with the spray head that Open Side Down.
The utility model passes through the first air inlet pipeline, the second air inlet pipeline, screen pack and reversing plate so that enters once
The air of blower fan is by fully filtering, and the switching operation for passing through reversing plate so that two air inlet pipelines can with alternately operating,
Alternately ash disposal, it is ensured that the long-time normal operation of primary air fan and boiler；By setting the first backflushing pipe, the second recoil
Pipeline can be anti-using being carried out by filtered air to another air inlet pipeline while an air inlet pipeline positive constantly inlet wind
Rush so as to automatically remove the dust on the filter screen in another air inlet pipeline；When removing dust on filter screen using backflushing pipe, lead to
Unlatching spray head is crossed, the high concentrate dust caused by operation that avoids recoiling, which is diffused into, influences the normal of another air inlet pipeline in air
Operation.
