Abstract
The invention relates to the field of sealing of activated lime shaft kilns and pipeline valves, in particular to a gas cooling device for a sealing ring. The gas cooling device is characterized by comprising a gas inlet pipeline, an annular channel and gas holes, the annular channel is arranged on the outer wall of a kiln tightly below the sealing ring, the tail end of the gas inlet pipeline is provided with a plurality of outlets connected with the annular channel, and the gas holes are evenly arranged at the top of the annular channel facing the sealing ring. 2-6 outlets are radially and evenly distributed around the circumference of the annular channel, the number of the outlets is preferably 4, and the diameter of each gas hole ranges from 0.1mm to 0.2mm. Compared with the prior art, the gas cooling device has the advantages that the sealing ring for a charging bell and a sealing surface is ensured to work for a long time within a high-temperature environmental range, gas leakage and ash leakage of the sealing ring are prevented, cooling effects can be intelligently controlled by a computer, production adjustment is facilitated, the cooling effects are remarkable, the sealing ring can be used for a kiln chamber with higher temperature, and the use range of the sealing ring is widened.
Description
Technical field
The present invention relates to the field of sealing technology of active lime shaft kiln and pipeline valve, particularly relate 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 the 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, by sealing-ring (3) sealing, kiln top sealing is by the physical environment cooling between kiln lid (1) and the kiln body (2), and 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, and 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 invention 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 the sealing-ring under the environment of high temperature gas, sealing-ring is lowered the temperature, prolong the work-ing life of rubber seal under the hot environment.
For achieving the above object, the present invention is achieved by 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 links to each other 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 invention has the beneficial effects as follows:
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 prolongs 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.

Among the figure: 1-kiln lid 2-kiln body 3-sealing-ring 4-admission passage 5-circular channel 6-pore 7-outlet 8-conduit bracket 9-flange 10-bolt
Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described further:
See Fig. 2 and Fig. 3, the gas cooling device that is a kind of sealing-ring of the present invention is implemented the status architecture synoptic 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 links to each other 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 admission passage 4 convenient fixed installations, 5 outsides are provided with flange 9 in the circular channel, and conduit bracket 8 links to each other by bolt 10 with flange 9.
In sealing-ring when cooling,, cryogenic gas is by admission passage 4 one end air inlets, through export 7, circular channel 5 and pore 6 ejections, sealing-ring 3 is cooled off; 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 cooperate 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 control air pressure.
