Description
Technical Field
The utility model relates to a rubbish stove technical field specifically is a rubbish stokehold front wall and preceding water-cooling wall arrangement structure that encircles.
Background
When the smoke of the fire grate of the waste incineration boiler is mainly in the downstream direction, the front arch water-cooled wall is longer. If the front wall and the front arch water-cooled wall are designed integrally, the bending moment of the front arch to the front wall can cause overlarge stress, and the structure of the front wall and the front arch water-cooled wall is shown in figure 1, wherein 1 is the integrated front wall and the front arch water-cooled wall, 2 is a feed inlet, 3 is a grate surface, 4 is an expansion joint, and 5 is a slag outlet. In addition, the expansion joint and the guide device of the expansion joint are difficult to control due to the large upward expansion amount of the front arch water-cooled wall.
SUMMERY OF THE UTILITY MODEL
Too big in order to solve current water-cooled wall stress, the poor problem of expansion joint structural reliability, the utility model provides a rubbish stokehold front wall and preceding hunch water-cooled wall arrangement structure, it can solve the too big problem of water-cooled wall stress, improves expansion joint structural reliability.
The technical scheme is as follows: a garbage furnace front wall and front arch water-cooled wall arrangement structure comprises a furnace hearth and a grate surface and is characterized in that a front wall water-cooled wall and a rear wall water-cooled wall and a front arch water-cooled wall which are separately arranged are arranged above the grate surface, a first expansion joint is arranged between the front arch water-cooled wall and the inner wall of the furnace hearth, a second expansion joint is arranged between the front wall water-cooled wall and the rear wall water-cooled wall above the furnace hearth, and a rigid beam limiting support mechanism is arranged on the front arch water-cooled wall.
The limiting and supporting mechanism is characterized in that the limiting and supporting mechanism comprises a rigid beam, first vertical plates are fixed on two sides of the rigid beam, longitudinal I-shaped steel is fixedly welded below the first vertical plates, a gap is reserved between the longitudinal I-shaped steel and the bottom of the rigid beam, transverse I-shaped steel supporting the longitudinal I-shaped steel is arranged in the gap, abdicating holes used for the longitudinal I-shaped steel are formed in the transverse I-shaped steel, second vertical plates are movably hung on the lower portions of two sides of the transverse I-shaped steel, the bottoms of the second vertical plates are welded with fins of a water-cooled wall, a comb plate is fixed at the center of the rigid beam, the bottoms of the comb plates are welded with the fins of the water-cooled wall, and limiting steel plates located on two sides of the upper end of the transverse I-shaped steel are arranged at the bottom of the rigid beam and close to the water.
Adopt the utility model discloses afterwards, the water-cooling wall of preceding arch and front wall water-cooling wall sectional type are arranged, have effectively solved the too big problem of water-cooling wall stress, and the expansion joint between front wall and preceding arch water-cooling wall and the burning furnace also adopts the segmentation design simultaneously, has optimized the product structure, has improved the reliability of expansion joint structure.
