In order to achieve the above purpose, the invention is realized by adopting the following technical scheme:
the smoke guide sleeve is arranged on a coke oven machine in a furnace top area and consists of a main smoke guide tube, an upper sleeve, a lower sleeve and a liquid seal structure, wherein the main smoke guide tube is connected with an external smoke guide tube through a sealing flange; the bottom end of the lower sleeve is matched with a smoke guide hole seat on the top of the coke oven to realize sealing connection.
The bottom end of the lower sleeve is a spherical surface or a conical surface, and is matched with the spherical surface at the top of the smoke guide hole seat to realize sealing connection.
The liquid seal structure comprises an annular liquid containing cylinder, an annular connecting plate and an annular inserting cylinder, wherein the annular liquid containing cylinder is arranged on the upper portion of the lower sleeve, the top of the annular liquid containing cylinder is of an open structure, the annular connecting plate is fixed on the outer side of the upper sleeve, the top of the annular inserting cylinder is fixedly connected with the annular connecting plate, and the bottom of the annular liquid containing cylinder is inserted into liquid contained in the annular liquid containing cylinder.
The liquid is water.
The annular liquid containing barrel is flexibly connected with the annular connecting plate through a plurality of lock chains arranged along the circumferential direction.
Compared with the prior art, the invention has the beneficial effects that:
1) The liquid sealing structure is arranged on the smoke guide sleeve mechanically connected with the coke oven at the top of the oven, so that the smoke leakage can be effectively avoided during smoke guide alignment operation, and meanwhile, the adverse effect caused by the fact that steam generated after a liquid medium in the liquid sealing structure is heated enters the carbonization chamber to normally produce the coke oven can be avoided;
2) Compared with the conventional furnace top smoke guide device, the smoke guide sleeve has the advantages of good smoke guide sealing effect, pollution reduction, accurate alignment, good adjustability, simple structure, low manufacturing cost, convenient maintenance and the like.

In the figure: 1. the main smoke guide tube 2, the upper sleeve 3, the lower sleeve 4, the liquid seal structure 5, the smoke guide hole 6, the smoke guide hole seat 7, the smoke guide hole cover 8, the sealing flange 9 and the lock chain
Detailed Description
The following is a further description of embodiments of the invention, taken in conjunction with the accompanying drawings:
as shown in fig. 1 and 2, the smoke guide sleeve of the coke oven top is arranged on a coke oven machine in a top area and consists of a main smoke guide tube 1, an upper sleeve 2, a lower sleeve 3 and a liquid seal structure 4, wherein the main smoke guide tube 1 is connected with an external smoke guide tube through a sealing flange 8, a plurality of upper sleeves 2 are vertically arranged at the bottom of the main smoke guide tube 1, the lower sleeves 3 are arranged in one-to-one correspondence with the upper sleeves 2, the lower sleeves 3 are suspended below the upper sleeves 2, the lower sleeves 3 are flexibly connected with the upper sleeves 2, and the liquid seal structure 4 is arranged between the upper sleeves 2 and the lower sleeves 3; the bottom end of the lower sleeve 3 is matched with a smoke guide hole seat 6 at the top of the coke oven to realize sealing connection.
The bottom end of the lower sleeve 3 is a sphere or a conical surface, and is matched with the sphere at the top of the smoke guide hole seat 6 to realize sealing connection.
The liquid seal structure 4 consists of an annular liquid containing cylinder, an annular connecting plate and an annular inserting cylinder, wherein the annular liquid containing cylinder is arranged on the upper part of the lower sleeve 3, the top of the annular liquid containing cylinder is of an open structure, the annular connecting plate is fixed on the outer side of the upper sleeve 2, the top of the annular inserting cylinder is fixedly connected with the annular connecting plate, and the bottom of the annular liquid containing cylinder is inserted into liquid contained in the annular liquid containing cylinder.
The liquid is water.
The annular liquid containing barrel is flexibly connected with the annular connecting plate through a plurality of lock chains 9 arranged along the circumferential direction.
Before the smoke guide starts, the smoke guide hole cover 7 is in a tightly covered state on the smoke guide hole 5. When the coke oven conducts smoke guiding operation, the smoke guiding hole cover 7 is removed, and the furnace top coke oven machine drives the smoke guiding sleeve to descend through the driving device, so that the lower sleeve 3 is tightly butted with the smoke guiding hole 5. The upper sleeve 2 and the lower sleeve 3 adopt split type structures, in the downward moving process of the smoke guide sleeve, the height of the lower sleeve 3 can be accurately adjusted according to the specific position of the smoke guide hole 5, so that the lower sleeve is accurately butted with the smoke guide hole 5, and then smoke guide operation is carried out. In the process of adjusting the height of the lower sleeve 3, the smoke leakage can be effectively prevented through the liquid seal structure between the lower sleeve and the upper sleeve.
According to the smoke guide sleeve at the top of the coke oven, the liquid seal structure is arranged on the smoke guide sleeve mechanically connected with the coke oven at the top of the coke oven, and is far away from the carbonization chamber when smoke guide operation is not performed, so that adverse effects caused by steam generated after a liquid medium (usually water) in the liquid seal structure is heated entering the carbonization chamber to normally produce the coke oven can be avoided.
The annular liquid containing barrel and the lower sleeve in the liquid sealing structure are connected with the upper sleeve through a plurality of lock chains 9, and the liquid sealing structure is simple in structure, convenient to adjust and capable of adapting to work in a high-temperature environment. When in use, the height of the lower cylinder body is adjusted in advance according to the position of the smoke guide hole, and the lower cylinder body can continuously work in a period of time without repeated adjustment.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
