Description
Technical field
The utility model relates to a kind of tuyere fastening structure that is used for the branch airduct.
Background technique
Dividing airduct is the parts that even hot blast is provided in the drying room.In order to reach the effect that blows out even hot blast, divide airduct that many air drafts mouth need be set, the high-temperature gas that blows out in the tuyere is prone to cause the tuyere distortion, and the exhaust outlet of tuyere often spacing be 8～10mm, therefore fixing tuyere and indeformable often very difficult accurately.
As shown in Figure 1, the fixing bolt 4 that passes through of existing first kind of tuyere is connected with set screw nut 7, and is connected with intermediate nut 6 in the exhaust outlet, and intermediate nut 6 has guaranteed the spacing of exhaust outlet.Loosening for preventing being connected of fixing bolt 4, intermediate nut 6 and set screw nut 7, fixing bolt 4 is connected with spring washer 5 with a side of exhaust outlet.The form that this structure adopts the high temperature fastening piece to connect can avoid the connection of tuyere loosening in a short time; But blown out down by long-term hot blast; Even if high temperature fastening piece and spring washer 5 are arranged; Each fastening piece still can inevitably produce creep strain, and then causes that the connection of tuyere is loosening, has a strong impact on dries quantity.On the other hand, the high temperature fastening piece costs an arm and a leg, and cost is higher; Specification is less, and the maintenance difficulty is installed.
As shown in Figure 2, existing second kind of tuyere two ends are fixed with fixed plate 8, and fixed plate 8 is fixedly connected on the tuyere plate through wing bolt and nut.With first kind of existing tuyere, it is inconvenient that the fastening piece of this structure is installed maintenance, costs an arm and a leg, and can produce creep strain, and then cause the loosening technical problem and the economical efficiency thereof of connection of tuyere.In addition, calculate according to intensity, the thickness of slab of this tuyere also must be thickeied, otherwise is prone to cause problem on deformation such as flange; Therefore, increased cost again further.
The model utility content
The technical problem that the utility model will solve is: connect easy becoming flexible in order to solve the existing tuyere that is used for the branch airduct, cost of production is big, and makes and install the difficult low technical problem of manufacturing efficiency that causes of maintenance.The tuyere fastening structure that is used for the branch airduct that the utility model provides a kind of and is connected firmly, manufacturing efficiency high and can reduce cost.
The utility model solves the technological scheme that its technical problem adopted: a kind of tuyere fastening structure that is used for the branch airduct; It comprises tuyere and tuyere button; Tuyere is used for to drying room uniform hot blast being provided; The tuyere two ends are fixedly connected with the tuyere plate, and the outlet of tuyere is fixed with exhaust outlet, and the two ends vertical fixing in the exhaust outlet outside has flange; The length direction of tuyere is provided with a plurality of tuyere buttons, and the tuyere fastener has straight plate, and the two ends of straight plate are socketed on the flange; The both sides vertical fixing of straight plate has flap, and flap is flush-mounted in the exhaust outlet, interference fit between the two ends of flap and the exhaust outlet; The expansion shape of tuyere button is a cross.
As preferably, the thickness of slab of tuyere button is 0.9～2.5mm.
In sum, structurally, be evenly equipped with a plurality of tuyere buttons on the length direction of tuyere, being connected firmly between tuyere and the tuyere button, the tuyere button can prevent tuyere and tuyere plate pressurized is inside, outward flanging; Flap is flush-mounted in the exhaust outlet, and interference fit between the two ends of flap and the exhaust outlet has guaranteed the spacing of exhaust outlet.
On economic benefit, the tuyere button is made simple and easy for installation, can enhance productivity; The tuyere buckle is thick little, and materials are few, and cost is little; A plurality of tuyere buttons and tuyere are connected firmly, and should not become flexible, and have reduced the thickness of slab of tuyere indirectly, have reduced cost of production.
The beneficial effect of the utility model is: this is used for connecting on the tuyere of branch airduct a plurality of tuyeres buckles, and can prevent that tuyere and tuyere plate pressurized are inside, outward flanging; Being connected firmly of tuyere and tuyere button, intensity is high, is difficult for becoming flexible, and can also further reduce the tuyere thickness of slab, reduces cost; It is little that tuyere is fastened as, and it is simple to make and install maintenance, and manufacturing efficiency is high.
