Description
Technical field
The utility model relates to a kind of distributor tightness system, relates in particular to a kind of tightness system that is used for blast-furnace distributor.
Background technology
In the blast furnace ironmaking process, distributor is very important in a blast furnace furnace roof equipment equipment, is mainly used in reasonable cloth in blast furnace; And realize the various cloth requirements of arts demand; Distributor accomplishes the cloth action through being installed in the intravital transmission mechanism of distributor case, because the distribution device of distributor needs rotation when cloth, so the distributor casing is connected with blast furnace chamber; Blast furnace gas just has an opportunity to get into the distributor casing like this; Thereby pollute the distributor transmission mechanism, and then the equipment that influences normal work-ing life, maintenance increased.The effect of sealing chamber mainly is to use nitrogen to intercept high temperature, blast furnace gas with pressure gets into the distributor casing.For this sealing chamber, require not only that device structure is simple, to intercept blast furnace gas respond well, but also require to practice thrift nitrogen use level in actual use.
There is following shortcoming in traditional distributor sealing chamber:
1, it is relatively poor that sealing chamber nitrogen intercepts the blast furnace gas effect.Coal gas gets in the distributor casing easily, makes that the intravital transmission mechanism of distributor case is polluted, and shortens the work-ing life of distributor transmission mechanism, has increased site examining and repairing intensity and number of times simultaneously, influences the carrying out of ordinary production, influences benefit.
2, nitrogen use level is big.Increase ironmaking cost.
In sum, be necessary to propose improved technique means, solve this problems referred to above.
Summary of the invention
The purpose of the utility model be to provide a kind of can good sealing effect, and the little distributor tightness system of nitrogen use level.
To achieve these goals, the said tightness system that is used for distributor of the utility model includes the annular seal space structure, and the said annular seal space structure that goes up has upper cavity, and said upper cavity one sidewall is the water-cooled trunnion; The gudgeon pivoted housing; Form between said water-cooled trunnion wall and the gudgeon pivoted housing and go up circumferential weld; And evenly offer a circle upper channel in the formation on the wall of the water-cooled trunnion of circumferential weld, this upper channel is from the horizontal by angle, and downward-sloping; Said circumferential weld one end of going up is communicated in pivoted housing cavity and casing, and the other end is communicated in high furnace cavity; Last nitrogen pipeline, the said nitrogen pipeline of going up is communicated in upper cavity.
Further, said a plurality of upper channel evenly is opened in the last outer wall upper edge week of water-cooled trunnion.
Further, annular seal space structure also has upper groove on this, and said upper groove is opened in the last outer wall upper edge week of water-cooled trunnion.
Further, it also includes the lower seal cavity configuration, and said lower seal cavity configuration has lower chamber; Said lower chamber one sidewall is a water-cooled chassis, forms between said water-cooled chassis wall and the gudgeon pivoted housing and evenly offers a circle lower channel on the wall that descends circumferential weld, said water-cooled chassis to form down circumferential weld; This lower channel is from the horizontal by angle; And downward-sloping, said circumferential weld one end down is communicated in casing, and the other end is communicated in high furnace cavity; Following nitrogen pipeline, said nitrogen pipeline down is communicated in lower chamber.
Further, said a plurality of lower channel evenly is opened in the outer wall upper edge week of water-cooled chassis.
Further, this lower seal cavity configuration also has the linchpin groove, and said low groove is opened in the following outer wall upper edge week of water-cooled trunnion.
Adopt the tightness system that is used for distributor of said structure, effectively solved sealing chamber sealing effectiveness difference that prior art exists for a long time always and nitrogen use level is big, cost is high problem.

Fig. 2 is part (I) enlarged view of Fig. 1;
Fig. 3 is part (II) enlarged view of Fig. 1.
Embodiment
In order better to understand the purpose of the utility model, characteristic and function are described in detail the structure and the function of a preferred embodiment of this practicality below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of the utility model one preferred embodiment, can be known by Fig. 1, and this distributor novel seal chamber can be divided into annular seal space structure and lower seal cavity configuration.The said annular seal space structure that goes up has upper cavity 4, and said upper cavity 4 one sidewalls are water-cooled trunnion 14; Gudgeon pivoted housing 16; Form between said water-cooled trunnion 14 walls and the gudgeon pivoted housing 16 and go up circumferential weld 5; And evenly offer a circle upper channel 7 in the formation on the wall of the water-cooled trunnion 14 of circumferential weld 5, this upper channel 7 is from the horizontal by certain angle, and downward-sloping; Said circumferential weld 5 one ends of going up are communicated in pivoted housing cavity 3 and casing 1, and the other end is communicated in high furnace cavity 11; Last nitrogen pipeline 2, the said nitrogen pipeline 2 of going up is communicated in upper cavity 4.Said lower seal cavity configuration has lower chamber 12; Said lower chamber 12 1 sidewalls are water-cooled chassis 15, form circumferential weld 9 down between said water-cooled chassis 15 walls and the gudgeon pivoted housing 16, evenly offer a circle lower channel 8 on the wall of circumferential weld under said water-cooled chassis 15 forms; This lower channel 8 is from the horizontal by certain angle; And downward-sloping, said circumferential weld 9 one ends down are communicated in casing 1, and the other end is communicated in high furnace cavity 11; Following nitrogen pipeline 13, said nitrogen pipeline 13 down is communicated in lower chamber 12.
Further, annular seal space structure also has upper groove 6 on this, and said upper groove 6 is opened in the outer wall upper edge week of water-cooled trunnion, is convenient to offering of upper channel 7;
Further, the nitrogen that flows into from last nitrogen pipeline directly is blown into circumferential weld 5 at a certain angle through said upper channel 7;
