Description
Technical field
The invention belongs to CFBB field, more particularly to a kind of 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 major part CFB boiler air distribution plate component uses bell-type windshield at present, by blast cap cover and wind
Bar is constituted, 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 there are problems that two during welding, one is that casting welding is easily cracked, insecure；Two be to remove to change
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, which weares and teares, needs periodic replacement, general during replacing to build material by laying bricks or stones using sledgehammer percussion, dismounting air distribution plate
Mode is handled, and workload is big, and the expense repaired and build material by laying bricks or stones is also added simultaneously.
The content of the invention
In order to overcome the defect of above-mentioned prior art, it is an object of the invention to provide a kind of CFBB cloth wind
Board component, to solve the problem of traditional spot welding connected mode of blast cap cover and wind bar is produced, also further reduces and changes taking for blast cap
With.
In order to achieve the above object, the technical scheme is that：
A kind of CFBB air distribution plate component, including air distribution plate 13, are fixed with wind bar 12 on air distribution plate 13,
Blast cap cover 11 is housed in the outer sheath of wind bar 12；The middle and lower part of wind bar 12 is provided with the boss 125 of fixed air distribution plate, wind bar 12
Portion is provided with the saddle 123 for accepting the lower edge of blast cap cover 11, and 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 and the fitted seal of seal groove 112 on the top of blast cap cover 11, the top dead center position of wind bar 12 are provided with attachment means
124, attachment means 124 are through the reserved connecting hole 114 in the top of blast cap cover 11 and fix.
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 present invention does not use welding manner to connect blast cap cover and wind bar, more laborsaving material-saving during installation, convenient and swift；Change
Blast cap cover need to only pull down nut, greatly eliminate the expense removed whole blast cap and build material by laying bricks or stones.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the structural representation of wind bar 12 of the present invention.
Fig. 3 is the structural representation of blast cap cover 11 of the present invention.
Embodiment
The embodiment to the present invention is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of CFBB air distribution plate component, including air distribution plate 13, it is fixed on air distribution plate 13
There is wind bar 12, blast cap cover 11 is housed in the outer sheath of wind bar 12；
As shown in Fig. 2 the middle and lower part of wind bar 12 is provided with the boss 125 of fixed air distribution plate, the middle part of wind bar 12 is provided with
The saddle 123 of the lower edge of blast cap cover 11 is accepted, 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
With the fitted seal of seal groove 112 on the top of blast cap cover 11, it is ensured that do not leaked out at blast cap perforation 114；The top dead center position of wind bar 12
Attachment means 124 are provided with, attachment means 124 are through the reserved connecting hole 114 in the top of blast cap cover 11 and fix.
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, and prevents the leakage of internal wind.
Be provided with protection platform 115 around the reserved connecting hole 114 in the top of described blast cap cover 11, effect be to protect through
Its attachment means 124 are not worn.
As shown in figure 3, the body lower part of blast cap cover 11, which is provided with conventional air outlet 111, top, is provided with seal groove 112
