Description
The utility model relates to the commutating device of a kind of pit kiln with mixed gas (or blast furnace gas), waste gas, air and waste gas, air.
Domestic common coke oven exchange shutter has three kinds: a kind of is the shutter (being the otto type) that is used for 58 Formed Coke Furnace, and it separates transmission because of blast furnace gas cock and shutter, and two sets of transmission mechanism make complex structure, is subjected to the transmission rig restriction can't realize quick commutation; The blast furnace gas cock is because of being positive pressure operation, and the gas leak amount is big, contaminate environment, and harm people's health, and also the cock maintenance capacity is big; Air scoop is located on two forks, and openings of sizes is limited.Another kind is the shutter that is used for the IIBP Formed Coke Furnace, can only be used to burn single kind of coal gas; Main moving rod perforate is shape hole, garden, and the tie rod track is an arc, so turnaround time is long, reaches 49 seconds.Also having a kind of is thallium formula binary exchange shutter, has replaced gas cock with the coal gas thallium, has solved the big and big problem of maintenance amount of gas leak amount; Couple structure makes easy to adjustly, and the thallium configuration of staggering in addition reduces transverse width, makes compact construction; Air scoop is located on the body surface, opening is bigger, being suitable for large capacity coke oven uses, but, because coal, waste gas thallium bar adjustable height are not to get Schwellenwert, reason such as two transmissions of the angle of each position end pawl and diplopore in addition, though main moving rod and tie rod connecting hole change the oval hole into by shape hole, garden, make the tie rod track change linear into by arc, but its commutating speed being still slower, is 46 seconds.
In view of the problems referred to above that exist, the purpose of this utility model is to design that a kind of commutating speed is fast under the situation that guarantees the coke oven safe operation, and swap time is the shortest, the thermo-efficiency height, and the coke oven of good sealing effect is with the dual seal shutter that commutates fast.
For realizing this purpose, the technical measures that the utility model is taked are: (1) coal gas thallium and waste gas thallium are two thallium structures, divide inside and outside thallium, and dual seal, trim are narrow planar annular, and in the coal gas thallium thallium to meet the gas face be recessed imitative streamlining.(2) switch of strict coal gas, waste gas, air and intermittent time and guaranteeing to design the reasonable angle of each transmission rig middle-end pawl, so that the stroke of coal gas thallium and waste gas thallium is the shortest under flow and the flow rate conditions by processing requirement.
The positively effect of taking abovementioned technology to produce is: (1) single hole patrilineal line of descent with only one son in each generation is moving, it is that recessed imitative streamlining resistance is little that the interior thallium of coal gas thallium is met the gas face, the reasonable angle of each position end pawl, the minimum stroke of coal gas thallium and waste gas thallium has all determined this shutter to commutate fast, it is the shortest that narrowed down to swap time, and make the temperature fluctuation of combustion chamber little, improved thermo-efficiency.(2) coal gas thallium and waste gas thallium are two thallium dual seals, and trim is narrow planar annular, makes good sealing effect, and leakage gas is not free from environmental pollution, has improved operational condition.
Introduce the utility model coke oven in detail with dual seal commutate fast structure, principle of operation and the process of shutter below in conjunction with drawings and Examples.
