Description
Technical Field
The utility model relates to a boiler reciprocating grate push rod technical field specifically is a seal structure that is used for reciprocating grate push rod to wear wall department.
Background
The sealing structure at the position where a push rod of a furnace recovery grate of a boiler penetrates through a wall is in a steel plate housing and skin sealing structure, as shown in figure 1, the steel plate housing and the skin sealing structure are adopted, one end of the skin is a square interface, the other end of the skin is a round interface, the skin is delivered to a site for a manufacturer in a whole block, after the push rod is installed, glue is cut and adhered to form on the site according to interface flanges at two ends of the skin, the site construction difficulty is high, and the appearance is not attractive; in the operation process, the push rod needs to do reciprocating motion, so that the problem of air leakage generated after the skin glue bonding part cracks due to improper glue selection or infirm bonding is easy to occur.
SUMMERY OF THE UTILITY MODEL
In order to solve the current push rod and wear wall department seal structure installation difficulty, the easy phenomenon that takes place to leak out of operation in-process, the utility model provides a seal structure for reciprocating grate push rod wears wall department, it can simplify the installation operation, solves the problem of leaking out.
The technical scheme is as follows: the sealing structure for the through-wall part of the push rod of the reciprocating grate comprises a steel plate housing and the push rod, wherein a first through hole is formed in the steel plate housing, one end of the push rod penetrates through the first through hole, a connecting pipe is installed at the through hole, the end part of the connecting pipe is welded and fixed with one end of a non-metal expansion joint, the other end of the non-metal expansion joint is welded and fixed with a flange, and the other end of the push rod penetrates through a second through hole in the flange and is fixedly connected with the flange.
The connecting pipe is further characterized in that the connecting pipe is a square connecting pipe, and the nonmetal expansion joint is a rectangular nonmetal expansion joint;
the flange comprises a first rectangular flange and a second circular flange, a third through hole is formed in the middle of the first rectangular flange, a matched fixing hole is formed in the first rectangular flange and the second circular flange around the third through hole, the first rectangular flange and the second circular flange are fixed through bolts and nuts, and the second through hole is formed in the middle of the second circular flange.
Adopt the utility model discloses afterwards, take over and nonmetal expansion joint can the snap-on connection, and the push rod is connected to the cooperation flange, installation easy operation, and the leakproofness obtains guaranteeing after the welding moreover, has reduced the phenomenon that leaks out to appear in the operation process.

Detailed Description
See fig. 2, fig. 3, and fig. 4, a sealing structure for a reciprocating grate push rod wall-through position, which comprises a steel plate housing 1 and a push rod 2, wherein a first through hole for one end of the push rod 2 to pass through is formed in the steel plate housing 1, a square connecting pipe 3 is installed at the through hole, the end part of the square connecting pipe 3 is welded and fixed with one end of a rectangular non-metal expansion joint 4, the other end of the rectangular non-metal expansion joint 4 is welded and fixed with a flange, and the other end of the push rod 2 penetrates through a second through hole in the flange and is.
The flange includes first rectangle flange 5 and the circular flange of second 6, and it has third through hole 7 to open in the middle of first rectangle flange 5, is provided with complex fixed orifices 8 on the first rectangle flange 5 around the third through hole 7 and on the circular flange of second 6, and first rectangle flange 5 passes through bolt and nut 9 with the circular flange of second 6 and fixes, has seted up second through hole 10 in the middle of the circular flange of second 6.
The rectangular non-metal expansion joint 4 needs to be sleeved on the push rod 2 in advance, wherein the diameter D2 of the third through hole 7 is larger than the maximum diameter D3 of the push rod 2, the second circular flange 5 is welded on the push rod 4, the diameter D1 of the second through hole 10 corresponds to the diameter of the cylindrical section of the push rod 4, welding and fixing are convenient, the square pipe 3 is connected with one end of the rectangular non-metal expansion joint 4, and the other end of the rectangular non-metal expansion joint 4 is connected to the second circular flange 6 through the first rectangular flange 5 and the bolt nut 9. In the figure 11 is a tube panel.
The utility model discloses a seal structure site operation is simple, because nonmetal expansion joint adopts whole producer to purchase, obtains improving in the quality after the shaping to the problem of leaking out that skin problem produced in the operation process has been reduced. The nonmetal expansion joint is connected with the flange through a bolt. The structure of the expansion joint is convenient for overhauling and replacing the non-metal expansion joint.
