Abstract
The utility model discloses a blast furnace coal spray gun which is applicable in spraying coal dust of metallurgy blast furnace and whose length can be adjusted. A fixed clip 8 is arranged at the outer ring at the sliding internal set 4. A locknut 5 screw thread is arranged at one end of the fixed clip 8. A movable clip 9 is arranged in the fixed clip 8. A coal spraying long pipe is through the central holes of the sliding internal set 4 and the movable clip 9 and the other end is arranged near a spraying pipe 1. A praying pipe connecting set 2 is suited at the outer ring which is against the spraying pipe 1 and the coal spraying long pipe 3. Before coal spraying, the spraying pipe 1, spraying pipe connecting with pipe 2, coal long pipe 3, movable clip 9 and seal ring 11 are assembled into a whole which is put into the sliding internal set 4 and then the movable clip is blocked in the fixed clip 8. The spraying pipe 1 is extended into the blast furnace wind gap. Coal spraying is carried out in the blast furnace. When the head of spraying pipe is burned and the entire spraying gun is not in the place, the locknut 5 will be loosen and the position of coal spraying long pipe will be moved (pulled) until the spraying pipe gets to a proper position. If the spraying pipe is fully damaged from burning, the spraying pipe connecting with set 2 will be loosen and the spray pipe 1 will be replaced for a new one. The coal spraying gun is applicable in blast furnace coal spraying with various nominal capabilities.
Description
Technical field
The utility model relates to a kind of spray gun that is applied to coal injection in the metallurgy high furnace stove, relates in particular to a kind of coal powder lance for blast furnace of adjusting coal spouting gun length.
Background technology
Coal injection is to reduce to consume the technique means that (as the reduction coke ratio) increases economic efficiency in stove in the metallurgy high furnace iron manufacturing process, one of instrument that must use in the coal powder injection process is a coal spouting gun, the length of coal spouting gun decides according to each blast furnace nominal capacity, various jet pipes can not be unified and coal spouting gun length also is fixed, if the position, front of coal spouting gun burns out to lead coal spouting gun is shortened in the coal powder injection process, need to change whole coal spouting gun, cause waste of material, increase production cost, and in operation, maintenance, increase very big workload in the replacing, influence the blast furnace operating rate that dusts, must increase coke consumption, improve coke ratio.
Summary of the invention
In order to solve the technical problem that prior art exists, it is a kind of reasonable in design, easy to use that the utility model provides, and can adjust the coal powder lance for blast furnace of the adjustable length of coal spouting gun winding-up position, reduction tuyere small sleeve and jet pipe consumption.
For achieving the above object, the technical solution adopted in the utility model is, design one sleeve fixture mechanism earlier, and this stationary installation is made of jet pipe, jet pipe adapter sleeve, coal powder injection long tube, movable clip and sealing-ring, and movable clip is sleeved in the fixation clamp.A central hole of passing stationary installation and movable clip of coal powder injection long tube, spout threads is enclosed within the jet pipe adapter sleeve.
Adopt the coal powder lance for blast furnace of a kind of adjustable length that as above technical scheme provides to compare with the existing fixedly coal spouting gun of spray gun length, its beneficial effect is:
1. this coal powder lance for blast furnace can be realized " stretching " adjusting of coal spouting gun by the coal spouting gun stationary installation, can be used on the spray gun of the various tuyere structures of blast furnace, and remedies the manufacturing installation error of actual air-supply arrangement;
2. the consumable accessory of this coal powder lance for blast furnace is a jet pipe, and remaining part is not fragile, and jet pipe burns out the back and changes easily, repeatedly uses, and is good in economic efficiency;
3. this coal powder lance for blast furnace is for a specific air-supply arrangement, and stationary installation of initial adjustment gets final product, and need not re-adjustment later on and changes, and uses easy to adjustly, and suitability is wide.
Description of drawings
Fig. 1 is the structural representation of the coal powder lance for blast furnace of a kind of adjustable length described in the utility model, also is specification digest accompanying drawing of the present utility model.
Fig. 2 is the stationary installation block construction synoptic diagram of the coal powder lance for blast furnace of described a kind of adjustable length.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
As shown in drawings, the coal powder lance for blast furnace of described a kind of adjustable length is by jet pipe 1, jet pipe adapter sleeve 2, coal powder injection long tube 3, sliding inner sleeve 4, set nut 5, stop pin 7, fixation clamp 8, movable clip 9 and sealing-ring 10 or 11 are formed, wherein the coal powder injection long tube 3, movable clip 9 is a prior art, one of fixation clamp 8 has groove, have on of groove open slot is arranged, fixation clamp 8 is sleeved on the periphery of sliding inner sleeve 4, set nut 5 screw threads are assemblied in an end of the fixation clamp 8 of open slot, and between fixation clamp 8 and sliding inner sleeve 4 are nested, sealing-ring 10 is arranged, movable clip 9 is stuck in the claw of fixation clamp 8, between movable clip 9 and the fixation clamp 8 sealing-ring 11 is arranged.A centre hole that passes sliding inner sleeve 4 and movable clip 9 of coal powder injection long tube 3, the inwall of the other end of coal powder injection long tube 3 and jet pipe adapter sleeve 2 one ends is connected, jet pipe 1 is threaded in the inwall of jet pipe adapter sleeve 2 the other ends, and jet pipe 1 is connected with coal powder injection long tube 3.Periphery at fixation clamp 8 medium positions is processed with chute 6, and stop pin 7 is connected mutually through the outer wall of chute 6 with sliding inner sleeve 4, guarantees that when rotating movable clip 9 fixation clamp 8 does not rotate.Protecting jacket 12 is sleeved on the periphery of fixation clamp 8 by set nut (5), and when sealing-ring 10 was ineffective, protecting jacket 12 can seal.
During enforcement, install coal spouting gun, sliding inner sleeve 4 is linked to each other with the spray gun anchor, make whole coal spouting gun motionless according to accompanying drawing.And arrive the position of blast-furnace tuyere according to required jet pipe, at first regulate the position of coal powder injection long tube 3 in sliding inner sleeve 4, movable clip 9 is stuck in the claw of fixation clamp 8, connect the coal powder injection flexible pipe of coming and the interface of coal powder injection long tube 3 from the coal powder injection workshop, the jet pipe 1 of coal powder lance for blast furnace is inserted in the blast-furnace tuyere, to coal powder injection in the State of Blast Furnace.When through after a while or through behind the Coal powder spray repeatedly, jet pipe 1 may burn out and shorten, operator unclamp set nut 5 earlier, move movable clip 9 coal powder injection long tube 3 is moved to left direction as shown in Figure 1, make jet pipe 1 can arrive the blast-furnace tuyere desired location.When jet pipe 1 burns out can not re-use the time fully, operator take off and burn out the jet pipe 1 that can not re-use, and the jet pipe 1 that more renews again comes into operation, and coal powder injection long tube 3 does not need more to renew, both reduced consumption, easy to operate again, coal injection operation by mistake.
