Description
Technical field
The utility model relates to a kind of central cooler, especially a kind of central cooler top petticoat pipe flexible seal device.
Background technology
In steel manufacture process, the sintered ring cold exhaust heat utilization has obtained increasing popularization.But because central cooler is not a workpiece, central cooler existence in service also exists this play to the situation of each different plaies between chassis top and the petticoat pipe; Existing seal can not effectively be eliminated the influence that this play causes sealing, thereby makes sealing just become a bottleneck, causes to have following crux in the use: between chassis top and petticoat pipe, have a large amount of cool ambient air to bleed; Influenced the temperature of utilizing of flue gas; Thereby reduced the quality that boiler produces steam, influence the whole generating system, especially when northern winter; Therefore influence then more hugely, be necessary existing central cooler is improved.
Summary of the invention
The purpose of the utility model is a kind of central cooler top petticoat pipe flexible seal device that designs for the deficiency that solves above-mentioned technology; This sealing device can solve the problem that a large amount of cold wind between chassis top and the petticoat pipe bleed, thereby improves the flue gas recirculation utilization rate and improve the flue gas utilization quality.
The central cooler top petticoat pipe flexible seal device that the utility model designed; It mainly comprises seal, seal support structure, drop bar and slide plate supporting structure; Said seal is fixedly installed on the ring cold machine smoke hood through the seal support structure; Said drop bar is fixedly installed on circular cooler trolley top through the slide plate supporting structure, and described seal is a steel spring plate; Described drop bar is obliquely installed, and said steel spring plate bottom and drop bar are fitted.
As preferably, described steel spring plate is a double-decker, and the design of double-layer spring steel plate can prolong service life of steel spring plate greatly, reduces unnecessary maintenance downtime, improves the UTILIZATION OF VESIDUAL HEAT IN time
As preferably, said seal support structure mainly is made up of fastening backing plate, the vertical supporting plate of seal, the horizontal supporting plate of seal, fastening bolt, seal pressing plate, horizontal gusset plate and perpendicular gusset plate; Said seal pressing plate, fastening backing plate, the vertical supporting plate with seal of steel spring plate set gradually and link together through fastening bolt; Horizontal supporting plate one end of said seal connects the vertical supporting plate of seal, the other end connects perpendicular gusset plate; Said perpendicular gusset plate top connects petticoat pipe, and said horizontal gusset plate is arranged between vertical supporting plate of seal and the perpendicular gusset plate; Described slide plate supporting structure mainly is made up of slide plate supporting gusset and the horizontal supporting plate of slide plate, and horizontal supporting plate one end of said slide plate connects drop bar, and the other end connects chassis; Said slide plate supporting gusset is positioned at the horizontal supporting plate of slide plate below, and one of which end and drop bar offset, the other end and chassis offset, and so not only steel spring plate and drop bar setting are more firm, and can play good sealing effectiveness.
As preferably, the vertical supporting plate with seal in the upper end of described drop bar is on same vertical line, and sealing effectiveness is best like this.
The central cooler top petticoat pipe flexible seal device of the utility model gained; Adopt steel spring plate,, reach the effect of sealing fully simultaneously to realize absorbing the play of the operating all directions of central cooler; Thereby improve the quality that fume afterheat utilizes; Reach the purpose that makes full use of of waste heat, and this version is cheap, operation expense is low; The central cooler top petticoat pipe flexible seal device of the utility model gained; Under the prerequisite that does not influence the cold technological process of former sintered ring, sealing version can absorb the play of all directions of central cooler generation in service, reaches sealing fully; Realize the complete alternation utilization of flue gas; Thereby greatly reduce station service power consumption rate, guarantee the better quality that fume afterheat utilizes, make stable, the operation efficiently of whole afterheat generating system.
