Description

Novel ascending pipe base of coke oven

Technical Field

The utility model belongs to the technical field of coke oven iron parts in a coke oven plant, and particularly relates to a novel ascending pipe base of a coke oven.

Background

The coke oven is a furnace kiln for refining coke by using blended coal, is a main thermal equipment for coking, takes the coke as a main purpose, the blended coal volatilizes tar, water vapor, ammonia, benzene, H2S, solid particles and the like at high temperature in the coking process to form combustible gas (crude gas), and the crude gas enters a gas evolution system through equipment pipelines such as an ascending pipe, a bridge pipe, a gas collecting pipe and the like to recover products. The part with higher temperature of the raw gas is at the riser, and the base of the riser is one part of the raw gas output, and the temperature and the corrosivity born by the base are the strongest.

The traditional riser base lining is made of refractory bricks, and is easy to pulverize and fall off at a high temperature for a long time, meanwhile, due to the fact that the circular structure is not enough, gaps exist in splicing places of the refractory bricks, raw coke oven gas gradually corrodes the tube wall through the gaps, and under a high-temperature environment, the temperatures such as burnthrough, deformation and cracking can occur in 3-6 months, and the raw coke oven gas needs to be replaced again.

SUMMERY OF THE UTILITY MODEL

The novel ascending pipe base for the coke oven overcomes the defects in the prior art, solves the problems that the existing ascending pipe base is easy to corrode, burn through, crack and leak smoke and has short service life, and aims to provide the novel ascending pipe base for the coke oven.

In order to solve the technical problems, the technical scheme adopted by the utility model is as follows: the utility model provides a novel tedge base of coke oven, includes square base and circular section of thick bamboo of inserting, is connected through the connecting cylinder between square base and the circular section of thick bamboo of inserting, and the connecting cylinder is inserted a section of thick bamboo with circular and is set up with one heart, and square base lower part and resistant firebrick contact segment are square structure resistant material brace table, and four bights of brace table have preset the bolt hole, and circular hole of inserting a section of thick bamboo is circular equally, and circular cushion cap of tedge is preset to circular bottom of inserting a section of thick bamboo for be connected with the tedge is concentric.

And sealing ceramic fibers are filled between the circular inserting cylinder and the ascending tube. Sealing ceramic fibers are also arranged between the bottom of the ascending pipe and the circular bearing platform of the ascending pipe.

The square base, the round inserting cylinder and the connecting cylinder are integrally formed by cast iron pouring.

And a refractory material is poured inside the connecting cylinder.

Compared with the prior art, the utility model has the following beneficial effects: the utility model has simple structure, scientific and reasonable design and easy production and manufacture, the square structure is firmly and reliably connected with the refractory brick of the coke oven body, the smoke leakage phenomenon caused by corrosion, cracking and other problems is reduced, the service life of the riser base is prolonged, the replacement frequency of the riser base is reduced, the environmental protection level of enterprises is improved, and the utility model has remarkable social and economic benefits.

The present invention will be described in further detail with reference to the accompanying drawings.

Fig. 1 is a schematic sectional structure of the present invention.

FIG. 2 is a schematic top view of the riser base.

FIG. 3 is a schematic view of the riser base in connection with a riser.

In the figure: the device comprises a square base 1, a circular inserting cylinder 2, a connecting cylinder 3, a supporting table 4, a bolt hole 5, a circular bearing platform 6 and an ascending pipe 7.

Detailed Description

In order to make the objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

As shown in figures 1-3, the novel ascending pipe base for the coke oven comprises a square base 1 and a circular insertion cylinder 2, wherein the square base 1 is connected with the circular insertion cylinder 2 through a connecting cylinder 3. The square base 1 and the connecting cylinder 3 are both made of cast iron. The lower part of the cast iron square base 1 and the contact part of the refractory bricks are a square supporting table 4, the supporting table 4 is provided with pre-embedded bolt holes 5, the outer ring of the ascending pipe 7 is provided with a flange (not shown in the figure), and the corresponding installation and connection of the bolt and the flange hole diameter of the existing ascending pipe 7 are firmer and more reliable.

The inner structure of the upper round inserting cylinder 2 is round, the inner lining is made of refractory materials, the round bearing platform 6 of the ascending pipe is arranged and can be concentrically connected with the ascending pipe 7, and ceramic fiber materials are filled in the gap part between the inner wall of the round inserting cylinder 2 and the outer wall of the ascending pipe 7 so as to ensure that raw coke oven gas does not leak.

The square base 1 is made of cast iron and has a square structure, can be combined with a refractory brick of a coke oven body, and is stable in structure, firm and reliable. In addition, the connecting cylinder 3 is internally provided with a poured refractory material which can form a crude gas heat-insulating layer together with the ascending pipe 7, and simultaneously, the crude gas can be prevented from being corroded. A circular bearing platform 6 is preset in the upper circular insertion barrel 2 and can be connected with an ascending pipe 7 more tightly. The square structure supporting table 4 of the square base 1 is provided with the pre-buried bolt holes 5, and the pre-buried bolt holes correspond to the flange hole diameter of the existing ascending pipe through bolts, so that the connection is firmer and more reliable.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
