Abstract
The utility model relates to a pipeline which is used for air blast for a blastfurnace. The pipeline comprises a metallic pipeline and an inner lining fireproof material of the metallic pipeline, wherein the metallic pipeline is composed of a bent pipe 6, corrugated pipes 2 and a belly pipe 9, wherein the corrugated pipes 2 are arranged at both ends of the bent pipe 6. The pipes are connected with flanges 3. Dilatation joints 1 are arranged in the corrugated tube 2 and the inner lining material, wherein the dilatation joints 1 are sealed by aluminium silicate fibre. The utility model is characterized in that a water cooling jacket 10 is arranged at the end part of the belly pipe 9; one end of the water cooling jacket 10 is communicated with a water ingress pipe 11, and the other end of the water cooling jacket 1 is communicated with a water egress pipe 12. The water cooling jacket 10 is installed on the outer circle of the inner lining material of the metallic pipeline, and the cross section of the water cooling jacket 10 is in the shape of a broken ring. A cooling system, which is additionally arranged at the end part of the belly pipe of the utility model, enables the blast branch pipe not to glow in use and enables the service life of the blast branch pipe to be obviously prolonged. Therefore, the regular production of the blastfurnace is guaranteed.
Description
One, technical field
The utility model relates to a kind of pipeline of blast furnace air-supply usefulness.
Two, background technology
Existing blast branch pipe of blast furnace is made of metal tube and internal lining pipe material.The internal lining pipe material that uses generally adopts clay matter water glass or phosphoric acid bonded ramming mass at present, large blast furnace generally adopts high alumina matter or corundum fireproof mould material, and these materials all do not match with metal tube, poor heat stability, the non-refractory airflow scouring, intensity is lower, and crackle easily takes place, and causes airduct in use easily rubescent, its work-ing life is short, be generally 1～2 month, and needed in the production process often to change, influenced the ordinary production of blast furnace.
Novel mould material has been adopted in " blast branch pipe of blast furnace " (ZL2003 2 0126279.5), though improved the operating mode of blowpipe, but variation because of wind pushing temperature, the belly pipe end of blowpipe, especially blowpipe still rubescent phenomenon can occur, not only influence its work-ing life, also influence the ordinary production of blast furnace.
Three, summary of the invention
The purpose of this utility model provides a kind of can improve work-ing life, can avoid the novel blast-furnace blowpipe that rubescent phenomenon occurs, can make the blast furnace ordinary production.
For achieving the above object, design philosophy of the present utility model is to set up water-cooling system in the belly pipe end described in the patented technology of " blast branch pipe of blast furnace " (ZL20032 0126279.5).
Concrete technical scheme is: the utility model is made of metallic conduit and metallic conduit inner lining refractory, metallic conduit is made of corrugated tube, the belly pipe at bend pipe and two ends, connect with flange between pipe, in corrugated tube and the inner lining material dilatation joint is arranged, dilatation joint is sealed with aluminum silicate fiber; Be provided with water jacket in the belly pipe end, an end of water jacket communicates with water inlet pipe, and the other end of water jacket communicates with rising pipe.
Wherein, water jacket is installed on the cylindrical of metallic conduit end, and the transverse section of water jacket is for separating ring-type.
Owing to adopt technique scheme, metallic conduit inner lining refractory that the utility model adopted and good, high, the high temperature resistant airflow scouring of intensity of metallic conduit coupling.Added dilatation joint in corrugated tube and metallic conduit inner lining refractory, the thermal distortion that fine alleviation airduct liner of energy and corrugated tube Yin Gaowen are produced; Especially the cooling system of being set up in the belly pipe end makes that blowpipe is in use not rubescent, obviously improve work-ing life, guaranteed the ordinary production of blast furnace.
Four, description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the A-A sectional structure chart of Fig. 1.
Five, embodiment
Present embodiment comprises metal conduit and metallic conduit inner lining refractory as shown in Figure 1, and metallic conduit is made of corrugated tube [2], the belly pipe [8] at bend pipe [6] and two ends, connects with flange [3] between pipe, and flange face seals with metal packing washer [5].Dilatation joint [1] is arranged in corrugated tube [2] and the inner lining material, and dilatation joint [1] is sealed with aluminum silicate fiber.Locate to be provided with vision slit [4] at bend pipe [6], belly pipe [8] is provided with coal spouting gun [7]
As shown in Figure 2, belly pipe [9] end is provided with water jacket [10], and an end of water jacket [10] communicates with water inlet pipe [11], and the other end of water jacket [10] communicates with rising pipe [12].Water jacket [10] is installed on the cylindrical of metallic conduit inner lining material [7], and the transverse section of water jacket [10] is for separating ring-type.
The metallic conduit inner lining refractory of present embodiment and good, high, the high temperature resistant airflow scouring of intensity of metallic conduit coupling.Especially the cooling system of being set up in the belly pipe end makes that blowpipe is in use not rubescent, obviously improve work-ing life, guaranteed the ordinary production of blast furnace.
