Description
Technical field
The utility model belongs to cigar mill power houses boiler-burner field, is used more particularly to a kind of boiler-burner
Air door structure.
Background technology
LOOS boiler-burners need to change spiral-flow type wind in real time according to situations such as combustion matter, burning degree in the course of the work
Door rotating speed, in actual motion, due to the frequent change of spiral-flow type air door rotating speed occur often spiral-flow type air door perform failure,
LOOS boiler-burners are shut down, and shorten the service life of the equipment, potential safety hazard be present, have impact on product quality, increase simultaneously
Add maintenance labor intensity and maintenance cost.
The content of the invention
The purpose of the utility model be for solve it is above-mentioned connected in the prior art between swirl vane and actuator it is insecure and
In the process of running a kind of boiler-burner air door structure is proposed the problem of frequent failure, shutdown.
The utility model is adopted the technical scheme that to reach above-mentioned purpose：A kind of boiler-burner air door structure,
Including eddy flow fan blade, the installation end of swirl vane is rear end, rectangular aperture is provided with the installation end of swirl vane, in rectangular aperture
The first mounting hole is arranged with other swirl vane, connector is embedded with rectangular aperture, is provided with and turns in the connector
Shaft mounting hole, flat key groove is provided with the inwall of shaft mounting hole, is provided with embedding slot in the top and bottom of connector, connector leads to
Cross embedding slot to be inlaid in rectangular aperture, second mounting hole corresponding with the first position of mounting hole is provided with connector.
Preferably, multiple first mounting holes are arranged with the swirl vane by rectangular aperture.
Preferably, it is provided with embedding slot in the front end of connector.
Had the beneficial effect that possessed by the utility model：Connector can be installed or removed quickly with swirl vane,
Convenient maintenance；On the other hand ensure that air door executer rotating shaft is not in loosening of swirl vane etc. when rotating by connector
What is connected insecure caused by situation between swirl vane and actuator and often break down in the process of running, shut down asks
Topic.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is Fig. 1 right view.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings.
As shown in figure 1, the utility model includes eddy flow fan blade 2, the installation end of swirl vane 2 is rear end, in swirl vane 2
Installation end be provided with rectangular aperture, multiple first mounting holes are arranged with the swirl vane 2 by rectangular aperture, are opened in rectangle
It is intraoral to be embedded with connector 4, shaft mounting hole 3 is provided with the connector 4, flat key groove is provided with the inwall of shaft mounting hole 3
1, embedding slot is equipped with the top of connector 4, bottom and front end, connector 4 is inlaid in rectangular aperture by embedding slot,
Connector 4 is provided with second mounting hole 5 corresponding with the first position of mounting hole.
When in use, connector 4 is inlaid in rectangular aperture first, then in the first mounting hole and the second mounting hole 5
Connector 4 is further fixedly connected by interior assembling bolt with swirl vane 2, finally assembles the rotating shaft of air door executer in rotating shaft
Mounting hole 3, this structure ensure that air door executer rotating shaft is not in the situations such as the loosening of swirl vane 2 when rotating and causes
Swirl vane and actuator between connect it is insecure and in the process of running often break down, shut down the problem of.
The present embodiment not makees any formal limitation, every foundation to shape of the present utility model, material, structure etc.
Any simple modification, equivalent change and modification that the technical essence of the utility model is made to above example, belongs to this reality
With the protection domain of new technique scheme.
