Abstract
The utility model relates to an annular sealing element, in particular to a sealing element with two spherical surfaces, which solves the problem that an amount of dense smoke escapes from a furnace mouth during loading coal into a coke furnace. The sealing element with two spherical surfaces comprises an upper sealing ring and a lower sealing ring, wherein an excircle on the lower end of the upper sealing ring is a spherical surface, an inner circle on the upper end of the lower sealing ring and an excircle on the lower end are both spherical surfaces, and the upper and the lower sealing rings are connected through a flexible connecting member. The annular sealing element makes up the defects of the prior art, prevents the smoke from escaping during the working of a sleeve (or a side sucker), realizes the universally sealing, greatly improves the smoke collecting rate, improves the purification efficiency of the system and is suitable for being widely used, and the utility model has the advantages of simple structure, low cost, good effect and the like.
Description
Technical field
The utility model relates to a kind of lip ring, is specifically related to a kind of pair of ball face sealing spare.
Background technology
In existing side-mounted tamping coke oven coal-charging furnace roof smoke gas treatment technology, mainly contain dual mode: (1) furnace roof collecting cart is collected the flue gas of coalingging that exhaust smoke hole is discharged, enter the dust suction main by bumping mouth, deliver to terrestrial station and purify, tail gas enters atmosphere through lift pump and aiutage.This purification style has been wasted a large amount of raw gas, and unavoidably the exhaust smoke hole place has a large amount of dense smokes to escape, and this part dense smoke can not become trapped in the dust suction main.(2) place the dust-removing vehicle of furnace roof to have two sleeves movably up and down, when coalingging, sleeve puts down, the collection flue gas of coalingging, through the burning of the combustion unit on the dust-removing vehicle, after through the cleaning apparatus dedusting, gas-liquid separator separates is arranged to atmosphere by chimney by induced draft fan.This purification style has been wasted a large amount of raw gas equally, and same inevitable fire door has a large amount of dense smokes to escape, and this part dense smoke can not become trapped in sleeve and burn.And present sealing means adopts following several structures mostly: 1. soft material sealing, and life cycle is short, non-refractory; 2. single ball face sealing, the deviation that can not regulate fire door; 3. sleeve seal is poorly sealed, can not play effect.
Summary of the invention
The utility model problem that a large amount of dense smokes in fire door place escape when solving coke oven coal-charging provides a kind of pair of ball face sealing spare.
The utility model adopts following technical scheme to realize: a kind of pair of ball face sealing spare, it comprises sealing-ring, lower seal, last sealing-ring lower end cylindrical is a sphere, and circle, lower end cylindrical are sphere in the lower seal upper end, and upper and lower sealing-ring connects by flexible link.Described flexible link is a chain.
A kind of side draught pipe device that sets two ball face sealing spares, the abutting end of the fire door of side draught pipe and coking chamber are installed two ball face sealing spares, and the last sealing-ring of two ball face sealing spares is fixed on side draught pipe pipe end.
During coke oven coal-charging, sleeve (or side draught pipe) device descends, and is installed in the two ball face sealing devices in furnace roof sleeve (or the side draught pipe) device, and the sphere between dependence coking chamber furnace access cap, seat makes two ball face sealing lower peripheral surfaces and fire door seal earlier.Sleeve (or side draught pipe) device continues to descend, the spacing of dwindling lower peripheral surface, and final two spheres up and down cooperate, sealing, make flue gas not escape.Two ball face sealing devices can be very easily and fire door centering, sealing.This device effect is obvious, reaches the zero release of furnace roof flue gas substantially.
The utility model has remedied the deficiencies in the prior art, flue gas escapes when having avoided the work of sleeve (or side draught pipe) device, reach universal driving fit, improved the capture rate of flue gas greatly, improved the purification efficiency of system, have simple in structure, expense is low, effective, advantage such as be fit to promote the use of.
Description of drawings
Fig. 1 is the structure and the scheme of installation of two ball face sealing spares
Among the figure: 1-side draught pipe, the last sealing-ring of 2-, 3-chain, 4-lower seal, 5-fire door
Embodiment
In conjunction with the accompanying drawings embodiment of the present utility model is further described, embodiment is used for illustrating of the present utility model, rather than it is carried out any restriction.
Two ball face sealing spares, it comprises sealing-ring 2, lower seal 4, and last sealing-ring 2 lower end cylindricals are sphere, and circle, lower end cylindrical are sphere in lower seal 4 upper ends, and upper and lower sealing-ring connects by flexible link.Flexible link is a chain 3.
Set the side draught pipe device of two ball face sealing spares, side draught pipe 1 is installed two ball face sealing spares with the abutting end of the fire door 5 of coking chamber, and the last sealing-ring 2 of two ball face sealing spares is fixed on the pipe end of side draught pipe 1.
Before the coke oven coal-charging, the coking chamber furnace access cap is opened, side draught pipe (or sleeve) device descends under the effect of lifting device, seal between the sphere of the lower end cylindrical of lower seal 4 and fire door 5 spheres, side draught pipe (or sleeve) device continues to descend, seal between round the sphere in the sphere of the lower end cylindrical of last sealing-ring 2 and the upper end of lower seal 4, each install in place after, begin to lead cigarette.Lead after cigarette finishes, two ball face sealing devices rise with side draught pipe device.
Claims (2)
1, a kind of pair of ball face sealing spare is characterized in that it comprises sealing-ring (2), lower seal (4), and last sealing-ring (2) lower end cylindrical is a sphere, and circle, lower end cylindrical are sphere in lower seal (4) upper end, and upper and lower sealing-ring connects by flexible link.
2, pair ball face sealing spare according to claim 1 is characterized in that described flexible link is chain (3).
