Abstract
The utility model relates to the fields of the sealing of an active lime shaft kiln and the sealing of a pipeline valve, and in particular relates to a gas cooling device for a sealing ring. The cooling device is characterized by comprising a gas inlet pipeline, an annular passage and gas holes, wherein the annular passage is arranged on the outer wall of a kiln body which is arranged closely below the sealing ring, the tail end of the gas inlet pipeline is provided with a plurality of outlets which are connected with the annular passage, and the gas holes are uniformly formed in the top of the annular passage in the direction facing the sealing ring, 2-6 outlets are uniformly distributed surrounding the circumference of the annular passage along the radial direction, preferably, the number of the outlets is four, and the diameters of the gas holes are 0.1-0.2mm. Compared with the prior art, the gas cooling device disclosed by the utility model has the following beneficial effects: (1) long time working of the sealing ring on a charging bell and the sealing ring on a sealing surface in a high-temperature environment can be ensured, and the occurrence of gas leakage and dust leakage can be prevented; (2) the computer intelligent control of the cooling effect can be achieved, thereby being conductive to production regulation; and (3) cooling effect is obvious so that the sealing ring can be used in a furnace chamber with high temperature, so that the application range of the sealing ring can be widened.
Description
Technical field
The utility model relates to the field of sealing technology of active lime shaft kiln and pipeline valve, particularly relates to a kind of gas cooling device of sealing-ring.
Background technology
at present, heat sink is not generally established in sealing place of active lime shaft kiln, make the applicable kiln type of sealed structure limited, in stopping property, weak point is all arranged on wearing quality and reliability, and guarantee that the reliable key of using of feeding device is life-time service and the reliability of kiln top bell sealed structure, see accompanying drawing 1, sectional view for its sealed structure, seal by sealing-ring (3) between kiln lid (1) and kiln body (2), kiln top sealing is by the physical environment cooling, sealing-ring (3) is subject to high-temperature gas impact in the kiln thorax, cause the aging acceleration of rubber seal, cause bell short sealing life, sealing effectiveness is difficult to keep, sealing effectiveness is subject to high-temperature gas and dust impact.
In recent years, along with maximization, seriation, the diversified development of active lime shaft kiln, the designed capacity of shaft furnace constantly increased, need the rational kiln top sealing heat sink of a kind of over-all properties, satisfy the shaft furnace variation, the needs of large scale development satisfy the needs of domestic lime industry.
Summary of the invention
The purpose of this utility model is to provide a kind of gas cooling device of sealing-ring, overcome the deficiencies in the prior art, cryogenic gas is guided to around sealing-ring under environment of high temperature gas, sealing-ring is lowered the temperature, extend the work-ing life of rubber seal under hot environment.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of gas cooling device of sealing-ring, comprise admission passage, circular channel and pore, the circular channel is arranged on the external wall of kiln of the tight below of sealing-ring, and the tail end of admission passage is provided with a plurality of outlets and is connected with the circular channel, and the top of circular channel evenly is provided with pore towards the sealing-ring direction.
Described outlet is 2～6 and radially evenly distributes around the circular channel circumference.
Described outlet is preferably 4.
Described hole diameter is 0.1～0.2mm.
Compared with prior art, the beneficial effects of the utility model are:
1) sealing-ring of assurance bell and trim works long hours in the hot environment scope, prevents that the grey phenomenon of sealing-ring gas leakage leakage from occuring, and sealing-ring extends work-ing life greatly.
2) cooling-down effect can be realized control with computational intelligence, is beneficial to produce to regulate.
3) cooling performance is remarkable, can make the kiln top sealing circle be used for increasing the use range of sealing-ring in the kiln thorax of higher temperature.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
See Fig. 2 and Fig. 3, the gas cooling device that is a kind of sealing-ring of the utility model is implemented the status architecture schematic diagram, comprise admission passage 4, circular channel 5 and pore 6, circular channel 5 is arranged on kiln body 2 outer walls of sealing-ring 3 tight belows, the tail end of admission passage 4 is provided with a plurality of outlets 7 and is connected with circular channel 5, and the top of circular channel 5 evenly is provided with pore 6 towards sealing-ring 3 directions.Pore 6 diameters are 0.1～0.2mm, preferred value 0.15mm.
In order to make the convenient fixed installation of admission passage 4,5 outsides are provided with flange 9 in the circular channel, and conduit bracket 8 is connected by bolt 10 with flange 9.
When sealing-ring was cooling, cryogenic gas was by admission passage 4 one end air inlets, through export 7, circular channel 5 and pore 6 ejections, carry out cooling to sealing-ring 3; The air input of admission passage 4 is subjected to computer control, as required sealing-ring 3 is carried out annular and cools, and guarantees the sealing of the reinforced process of kiln thorax reliably and with long-term.
Adopt initiatively cooling method of gas, can prevent that tightness system from owing to being heated for a long time, failure phenomenon occuring.Heat sink can coordinate with computer, realizes intelligent control according to the production technique needs, guarantees work-ing life and the sealing effectiveness of tightness system.Heat sink can prevent that dust from entering air-channel system by controlling air pressure.
