specific Embodiment approach 1

[0020] Specific Embodiment 1: The connection structure between the ascending cylinder and the descending cylinder of the gasification furnace in this embodiment, the gasification furnace includes the ascending cylinder 1, the descending cylinder 2, and the upper and lower ends of the ascending cylinder 1 are provided with 6 to 12 Ts Shaped support assembly, the T-shaped support assembly is made up of spacer plate 3 and connecting plate 4, a plurality of circular holes 5 are set on the ascending cylinder 1, a plurality of waist-shaped holes 6 are set on the connecting plate 4, and the circular holes 5 and the number of waist-shaped holes 6 are the same, and the axes of the corresponding round holes 5 and 6 are coincident. The ascending cylinder 1 is bolted to the connecting plate 4 through hexagonal bolts 7 and hexagonal nuts 8 .

[0021] The beneficial effect of this implementation mode:

[0022] 1. The connection structure and manufacturing method of the ascending cylinder an...

specific Embodiment approach 2

[0024] Embodiment 2: This embodiment differs from Embodiment 1 in that: one end of the distance plate 3 is welded to the connecting plate 4 , and the other end of the distance plate 3 is welded to the descending cylinder 2 .

[0025] Other steps are the same as in the first embodiment.

specific Embodiment approach 3

[0026] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that: 6 to 12 groups of hole groups are evenly distributed around the upper and lower ends of the ascending cylinder 1, and each group of hole groups includes 4 round holes 5, and The four round holes 5 are arranged in a square; the connecting plate 4 is provided with four waist-shaped holes 6, and the four waist-shaped holes 6 are arranged in a square.

[0027] Other steps are the same as those in Embodiment 1 or 2.

Abstract

The invention provides a connecting structure for a rising cylinder and a descending cylinder of a gasification furnace and a manufacturing method and relates to the technical field of designing and manufacturing of the rising cylinder and the descending cylinder of the gasification furnace. The connecting structure for the rising cylinder and the descending cylinder of the gasification furnace aims at solving the problems of unreasonable hole structure, high manufacturing difficulty, poor machining and manufacturing quality and low production efficiency of the rising cylinder and the descending cylinder of the gasification furnace. The gasification furnace comprises the rising cylinder, the descending cylinder and 6-12 T-shaped supporting components which are arranged at the upper and lower ends of the rising cylinder; the T-shaped supporting components consist of distance plates and connecting plates; multiple circular holes are formed in the rising cylinder; multiple waist-shaped holes are formed in the connecting plates; the number of the circular holes is the same as that of the waist-shaped holes; the axes of the corresponding circular holes coincide with the corresponding waist-shaped holes; and through hexagon bolts and hexagon nuts, the rising cylinder is connected with the connecting plates through bolts. The invention provides the connecting structure for the risingcylinder and the descending cylinder of the gasification furnace and the manufacturing method.

Description

technical field [0001] The invention relates to the technical field of design and manufacture of an ascending cylinder and a descending cylinder of a gasification furnace. Background technique [0002] Such as Figure 1 ~ Figure 4 As shown, for a long time, in the quenching chamber of the coal-water slurry gasifier, the outer ascending cylinder is assembled with the T-shaped support assembly on the inner descending cylinder through fasteners, and eight groups of holes are evenly distributed circumferentially at the upper and lower ends of the ascending cylinder. , each hole group consists of four waist-shaped holes, four round holes and a T-shaped support component. Among them, the waist-shaped hole is processed on the rising cylinder, and the round hole is drilled on the connecting plate. Wire, manual plasma cutting and grinding" methods for processing. Due to the relatively large size of the ascending cylinder, it is difficult to process the waist-shaped hole on the asce...
