Description
Technical field
The utility model belongs to CFBB field, more particularly to CFBB air distribution plate component.
Background technology
Blast cap is the important component of CFBB, which determine CFBB whether can safely, warp
Help and stably run, the blast cap in current most of CFB boiler air distribution plate component uses bell-type windshield, by blast cap cover and wind
Bar forms, conventional to be connected form using blast cap cover lower edge and wind bar (or wind bar boss) spot welding.Due to wind bar and blast cap cover
All it is casting, therefore two is present during welding, first, casting welding easily cracks, it is insecure；Changed second, removing
Or when checking blast cap, it is necessary to blast cap can be just removed after pad is cleared up, and it is all alloy electrode typically to weld use, very
Hardly possible polishing.On the other hand, blast cap abrasion needs to regularly replace, and is typically tapped using sledgehammer during replacing, removes air distribution plate and build material by laying bricks or stones
Mode is handled, and workload is big, also adds the expense repaired and build material by laying bricks or stones simultaneously.
The content of the invention
The defects of in order to overcome above-mentioned prior art, the purpose of this utility model are to provide CFBB cloth wind
Board component, to solve the problems, such as that blast cap cover produces with wind bar tradition spot welding connected mode, also further reduce and change taking for blast cap
With.
In order to achieve the above object, the technical solution of the utility model is：
CFBB air distribution plate component, including air distribution plate 13, are fixed with wind bar 12 on air distribution plate 13, in wind bar
12 outer sheaths are equipped with blast cap cover 11；The middle and lower part of wind bar 12 is provided with the boss 125 of fixed air distribution plate, and the middle part of wind bar 12 is set
There is the saddle 123 for accepting the lower edge of blast cap cover 11, the top of wind bar 12 is provided with air holes 121, and the top of wind bar 12 is provided with sealing station
122 are provided with attachment means 124 with the fitted seal of seal groove 112 on the top of blast cap cover 11, the top dead center position of wind bar 12, connect
Device 124 is through the reserved connecting hole 114 in the top of blast cap cover 11 and fixes.
The described lower edge of blast cap cover 11 sets lower edge to seal 113, and lower edge sealing 113 is interior with wind lever bracket platform 123
Wall seal groove 1231 coordinates.
Protection platform 115 is provided with around the reserved connecting hole 114 in the described top of blast cap cover 11.
The utility model does not use welding manner connection blast cap cover and wind bar, more laborsaving material-saving during installation, convenient and swift；
Nut need to only be pulled down by changing blast cap cover, greatly eliminate the expense removed whole blast cap and build material by laying bricks or stones.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model wind bar 12.
Fig. 3 is the structural representation of the utility model blast cap cover 11.
Embodiment
Specific embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, CFBB air distribution plate component, including air distribution plate 13, it is fixed with wind on air distribution plate 13
