Description
Technical Field
The utility model belongs to the technical field of expansion joints, and particularly relates to an expansion joint for a cone of a decomposing furnace.
Background
Expansion joints are a flexible structure provided on the vessel shell or pipe in order to compensate for additional stresses caused by temperature differences and mechanical vibrations. The expansion joint is used as an elastic compensation element capable of freely stretching, has the advantages of reliable work, good performance, compact structure and the like, and is widely applied to the fields of chemical industry, metallurgy and the like.
In actual production, an air root valve is required to be installed on a kiln tail decomposing furnace cone of a 5000t/d cement clinker production line, an original expansion joint (at a straight section position at the lower part of the decomposing furnace cone) is required to be removed, and an air root valve is installed, but because the air root valve is larger, the distance of the decomposing furnace cone is shorter, and the expansion of the decomposing furnace in a thermal state is considered, the expansion joint for the cone is required to be installed, but at present, the common expansion joint is used on a straight pipeline, and the installation requirement of the decomposing furnace cone is difficult to meet.
Disclosure of Invention
The utility model provides an expansion joint for a cone of a decomposing furnace, which can be used for installing a wind root valve on the cone of the decomposing furnace to meet the installation requirement on the cone.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
an expansion joint for a decomposing furnace cone, the expansion joint being tapered, comprising: the expansion joint comprises an expansion joint lower shell, an expansion joint upper shell, an upper sealing plate, a lower sealing plate and a middle corrugated pipe (aluminum silicate fiber cotton is filled in the expansion joint lower shell and the expansion joint upper shell are respectively arranged at the upper end and the lower end of the corrugated pipe, and the upper sealing plate and the lower sealing plate are used for sealing a filler between the corrugated pipe and the sealing plate; the decomposing furnace cone is divided into two sections, the upper shell of the expansion joint is welded on the decomposing furnace upper cone, and the lower shell of the expansion joint is welded on the decomposing furnace lower cone; the inner diameter of the upper shell of the expansion joint is larger than that of the lower shell of the expansion joint, so that the installation of a cone of a decomposing furnace is met, in addition, the middle filler of the corrugated pipe is sealed through the upper flange baffle plate and the lower flange baffle plate, and the two flange baffle plates are not contacted with each other, so that the expansion effect of the cone is achieved.
The beneficial effects are that: the utility model provides an expansion joint for a cone of a decomposing furnace, which solves the problem of shorter distance between the cone of the decomposing furnace when a wind root valve is installed, and the inner diameters of upper and lower flanges of the expansion joint are different in size, so that seamless connection of the cone is achieved, the condition that the distance between the cone is insufficient, the angle of the cone is ensured to be unchanged, and the expansion joint can be used for installing the wind root valve on the cone of the decomposing furnace and meets the installation requirement on the cone.

FIG. 1 is a schematic view of an expansion joint mounted on a cone according to an embodiment of the present utility model;
in the figure, a lower shell of a 1-expansion joint, an upper shell of a 2-expansion joint, a 3-upper sealing plate, a 4-lower sealing plate, a 5-corrugated pipe, an upper cone of a 6-decomposing furnace, a lower cone of a 7-decomposing furnace and 8-aluminum silicate fiber cotton.
Description of the embodiments
The utility model is described in detail below with reference to the attached drawings and the specific embodiments:
as shown in fig. 1, an expansion joint for a cone of a decomposing furnace is in a cone shape, and is arranged in the middle of the cone of the decomposing furnace for prolonging or shortening the distance between the cones; comprising the following steps: an expansion joint lower shell 1, an expansion joint upper shell 2, an upper sealing plate 3, a lower sealing plate 4 and a corrugated pipe 5; the expansion joint lower shell 1, expansion joint upper shell 2 are installed respectively in the upper and lower both ends of bellows 5, and upper seal plate 3 top is installed in expansion joint upper shell 2 bottom, and lower seal plate 4 bottom is installed in expansion joint lower shell 1 upper end, packs aluminium silicate cellucotton 8 between upper seal plate 3, lower seal plate 4 and the bellows 5, and upper seal plate 3, lower seal plate 4 are installed in the bellows both ends and are used for sealing the inside filler of bellows.
The decomposing furnace cone is divided into two sections, the upper expansion joint shell 2 is welded on the upper decomposing furnace cone 6, and the lower expansion joint shell 1 is welded on the lower decomposing furnace cone 7; the inner diameter L1 of the upper shell 2 of the expansion joint is larger than the inner diameter L2 of the lower shell 1 of the expansion joint, so that the installation of the cone of the decomposing furnace is met, the distance of the cone of the decomposing furnace is insufficient due to the installation of the expansion joint, the cone angle is kept unchanged, the wind root valve can be installed on the cone of the decomposing furnace, and the installation requirement on the cone is met.
The foregoing is merely a preferred embodiment of the present utility model and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present utility model, which are intended to be comprehended within the scope of the present utility model.
