The wall of the upper end of the funnel cap body is upward extended and forms a concave on the upper part of the funnel cap body. The bottom of the funnel cap is inward shrunk along the radial direction and forms a locating ring. The notch is arranged on the locating ring. The funnel cap body is sheathed on a hollow connection pipe. The upper part of the connection pipe is provided with a flange along the radial direction. The flange and the notch on the funnel cap body are mutually matched and connected. The device adopted, the funnel cap can be easily assembled or disassembled from the connection pipe.
Description
Technical field
The utility model belongs to the accessory on a kind of boiler, specifically a kind of blast cap.
Background technique
The blast cap that is installed on the circulating fluidized bed boiler air distribution plate is the strength member that guarantees goods fluid, has many multi-form blast caps to be applied in circulating fluidized bed boiler at present.The connecting means of blast cap body or blast cap overcoat and connecting tube mainly contains three kinds: a. welding, and b. is threaded, and c. is sitting in by own wt on the refractory material of air distribution plate, and all there are some problems in these three kinds of Placements.Adopt welding method, later blast cap body is subjected to the fluidized bed material wearing and tearing and is difficult for changing when influencing performance; Adopt threaded connection method, also run into same problem, boiler operatiopn Apoplexy cap screw thread under the furnace high-temperature baking lost efficacy easily, when changing the blast cap body dismounting all very difficult, the third method then will strengthen the weight of blast cap body self, pushes down the upwards thrust that blast produces.
Summary of the invention
The purpose of this utility model is to design a kind of faucet type linkage structure of blast cap, with convenience installation or removal blast cap on connecting tube.
According to design proposal provided by the utility model, the inside of blast cap body is cavity, and upper end closed is provided with through hole on the wall of blast cap body bottom, it is characterized in that: radially projection or notch are set in the bottom of blast cap body.
The upper end wall of blast cap body extends upward, and forms pit on the top of blast cap body.Radially inwardly shrink the bottom of blast cap body, forms positioning ring, and above-mentioned notch is opened on the positioning ring.
During use, the blast cap body should be enclosed within on the connecting tube of hollow, and the top of connecting tube is provided with flange radially, and flange cooperatively interacts with notch on the blast cap body and is connected.
The another kind of Placement of blast cap body and connecting tube is: the blast cap body is enclosed within on the connecting tube of hollow, and the top of connecting tube is provided with the positioning ring extend radially outward, offers bayonet socket on positioning ring, and this bayonet socket cooperatively interacts with projection on the blast cap body and is connected.
The supporting ring that the connecting tube utilization is arranged at its underpart is installed on the air distribution plate in the burner hearth, laying thermal insulating material and Fire and abrasion resistant material on air distribution plate, blast cap body be positioned at Fire and abrasion resistant material above.
The utility model has the advantages that: adopt the faucet type Placement, utilize the bayonet base principle, at the bottom of former blast cap body setting positioning ring radially, at positioning ring notch is set, corresponding flange is set on the connecting tube cylindrical, when blast cap is installed, the notch of blast cap body is faced flange on the connecting tube, insert the back rotation, allow flange on the connecting tube push down positioning ring on the blast cap body, just can prevent that the blast cap body from being moved by wind.In like manner open bayonet socket on the positioning ring of connecting tube, on blast cap body inwall projection is set, insert the back rotation, the company's of allowing positioning ring is pushed down the projection on the blast cap body inwall, can prevent that also the blast cap body from being moved by wind.

Fig. 3 is the utility model mounting point figure.
Embodiment
As shown in the figure: the supporting ring 14 that connecting tube 8 utilization is arranged at its underpart is installed on the air distribution plate 3 in the burner hearth 1, laying thermal insulating material 10 and Fire and abrasion resistant material 9 on air distribution plate 3, Fire and abrasion resistant material 9 is stretched out in the upper end of connecting tube 8, and blast cap body 7 is installed on the connecting tube 8.Air-flow enters in the connecting tube 8 from the lower end of connecting tube 8, enters in the blast cap body 7 through the upper end, and then enters burner hearth 1 bottom by the through hole on the blast cap body 7 11.
The inside of blast cap body 7 is cavity, and upper end closed forms the cap shape, and through hole 11 is set on the wall of blast cap body 7 bottoms, so that ventilate, projection 13 radially is set in the bottom of blast cap body 7.Corresponding bayonet fittings on utilizing this projection 13 and being arranged at connecting tube links together blast cap body 7 and connecting tube 8 easily, and this seizing type linkage structure is convenient especially when changing blast cap, only needs to rotate blast cap, just desirable blast cap down.
Radially inwardly shrink the bottom of blast cap body 7, forms positioning ring, is used for guaranteeing between blast cap body and the connecting tube equidistant, and above-mentioned notch is opened on the positioning ring.The top of connecting tube 8 is provided with flange 12 radially, and flange 12 cooperatively interacts with notch on the blast cap body 7 and is connected.During use, blast cap body 7 is enclosed within on the connecting tube 8 of hollow, notch on the blast cap body 7 is aimed at flange 12 on the connecting tube 8 toward pressing down, and then rotation, makes flange 12 on the connecting tube 8 push down positioning ring on the blast cap body 7, and blast cap body 7 is fixed on the connecting tube 8; When needs are dismantled, same as long as rotate blast cap body 7, make notch on the blast cap body 7 aim at flange 12 on the connecting tube, up pull out then, just desirablely go out blast cap body 7.
As another kind of form, also can the positioning ring that extend radially outward be set on the top of connecting tube 8, on positioning ring, offer bayonet socket, this bayonet socket cooperatively interacts with projection 13 on the blast cap body 7 and is connected.Blast cap body 7 is enclosed within on the connecting tube 8 of hollow during use, and bayonet socket alignment protrusion 13 toward pressing down, is rotated blast cap body 7 again, makes positioning ring on the connecting tube 8 push down projection 13 on the blast cap body 7, and blast cap body 7 is fixed on the connecting tube 8, and is during dismounting, same as described above.
The upper end wall of blast cap body 7 extends upward, and forms pit 15 on the top of blast cap body 7, utilizes this pit 15 can effectively reduce the wearing and tearing at blast cap body 7 tops, prolongs its working life.
