Abstract
The utility model provides a blast-furnace gas spread device and comprises a spread barrel. The spread barrel is connected with a bonnet which is connected with a toothed rack. The toothed rack is meshed with a sector gear which is fixed with a lever through a shaft. The upper portion of the spread barrel is provided with a spread hole of which the upper portion is provided with a sealing ring. When spreading gas, the lever drives the toothed rack through the sector gear to lift the spread barrel up and gas flow is discharged from the spread hole to form a multi-mouth shared frequency resonance to lower noise. After the spread is finished, the sealing ring enters a valve base to cut off the gas flow, obstructs dust below the sealing ring to lead the spread device to be closed under the dust-free state, and avoids blowing-loss to lead the working life of utilization of the device largely to extend and to lead the possibility of blast-furnace damping-down production-down to be largely lowered.
Description
Technical field
The utility model relates to a kind of device of dust-laden gas discharging, particularly a kind of bleeding device that is used for the discharging of iron-smelting blast furnace furnace roof coal gas.
Background technology
The blast furnace that metallurgy industry is used to smelt iron produces a large amount of dust-laden coal gas in process of production.According to ironmaking production technique and security needs, the each blow-on of blast furnace, blowing out, overhaul and when being in accidental state, all need dust-laden coal gas is diffused.Coal gas diffusion need be finished by the coal gas diffusion device.The present Bleeding Device of Blast Furnace Gas that adopts---diffuse valve, valve gap directly is fixed on an end of lever, valve gap is that the center of circle rotates up and opens with the lever shaft during emission coal gas, and the coal gas vertical row is in the air, because dust content of gas is big, make horizontally disposed valve base surface dust stratification, when stopping to diffuse, because the valve gap edge far from lever shaft radius centered difference, causes the valve gap circumferential direction not contact with valve seat simultaneously, early clamp dust between contact site valve gap and the valve seat bonding surface, cause poorly sealed; If do not clamp dust between valve gap and the valve seat bonding surface, also can be along with diffusing reducing of area, gas speed is accelerated, and it is big that surging force becomes, and causes valve gap and valve seat to touch the position than delayed completion and blow damage because of being hit too much; The single vertically upward mouth eruption of air-flow during this gas bleeding valve emission coal gas, noise is bigger, and environment is also constituted certain sound pollution.
Summary of the invention
The purpose of this utility model is, a kind of longevity type blast furnace coal gas diffusion device is provided, and it can make valve gap valve seat circumferential direction contact synchronously, can avoid the valve gap valve seat to decrease in conjunction with top blast, can reduce and diffuse noise.
The utility model for achieving the above object, by the following technical solutions: it diffuses tube, diffuses tube upper end and is connected with valve gap, valve gap is connected with the tooth bar lower end again, tooth bar and toothed segment mesh, toothed segment is fixed together by lever shaft and lever.The no flank of tooth of tooth bar rolls with the shelves wheel and cooperates.Diffuse on the circumference compartment of terrain and have and diffuse the hole, above diffusing the hole, sealing-ring is arranged.
The utlity model has following advantage: during emission coal gas, toothed segment makes the tooth bar vertical movement under the driving of lever, make diffuse the tube rise with valve gap, coal gas stream from diffuse on the tube diffuse the hole to around discharging, avoided coal gas stream to directly the washing away of valve gap valve seat bonding surface, and formed the simultaneous resonance of speaking out of turn and to reduce noise.Diffuse finish after, valve gap descends with diffusing tube, diffuses sealing-ring on the tube and at first enters valve seat and cut off coal gas stream, dust is intercepted below sealing-ring, can effectively avoid clamping dust between valve gap and the valve seat bonding surface, bleeding device is closed under dustless state, avoid blowing damage.

Embodiment
Bleeding Device of Blast Furnace Gas of the present utility model, it diffuses tube 2, and the upper end of diffusing tube 2 is connected with valve gap 1, and valve gap 1 is connected with tooth bar 10 lower ends again, tooth bar 10 and toothed segment 11 engagements, toothed segment 11 is fixed together by lever shaft 7 and lever 12.The no flank of tooth of tooth bar 10 rolls with shelves wheel 8 and cooperates.Diffuse on tube 2 the circumference compartment of terrain and have and diffuse hole 5, diffuse hole 5 above sealing-ring 6 is arranged.The utility model is when emission coal gas, by method activation lever 12 1 ends such as windlass lay winding wire ropes or hydraulic ram withdrawals, make lever 12 drive toothed segment 11, make tooth bar 10 vertical movements, make and diffuse tube 2 with valve gap 1 rise, coal gas stream from diffuse on tube 2 circumference diffuse hole 5 to around discharging, avoided coal gas stream to directly the washing away of valve gap 1 valve seat 3 bonding surfaces, and diffused hole 5 and can form the simultaneous resonance of speaking out of turn and produce and reduce anti noise.The other end of lever 12 has weight 9, after coal gas diffusion finishes, windlass discharges wireline or hydraulic ram stretches out, under the effect of weight 9 and lever 12, toothed segment 11 drives tooth bar 10 and moves downward, valve gap 1 is descended with diffusing tube 2, the sealing-ring 6 that diffuses on the tube 2 at first enters valve seat 3 and cuts off coal gas stream, intercept dust at sealing-ring below 6, effectively avoid clamping dust between valve gap 1 and valve seat 3 bonding surfaces, bleeding device is closed under dustless state, avoid blowing damage, this bleeding device is prolonged work-ing life significantly, blast furnace staying stopping production probability is reduced significantly.
