Abstract
The utility model belongs to a pulverized coal reaction lock hopper which comprises a barrel (1), a transition section (8), an upper pipe connecting flange (3) and a lower pipe connecting flange (6). The lock hopper is characterized in that a conical shell (7) is welded between the transition section (8) and the lower pipe connecting flange (6); the conical shell (7) is formed by fixedly connecting multiple middle segments (7-2), a left segment (7-1) and a right segment (7-3) together by using assembled and welded segment weld joints (7-4). The pulverized coal reaction lock hopper disclosed by the utility model is material-saving and convenient to machine, and ensures the quality requirements.
Description
Technical field
The utility model belongs to reaction unit, a kind of coal dust reaction lock hopper of particularly using in Coal Chemical Industry MEK production equipment.
Background technology
In Coal Chemical Industry is produced, lock hopper is one of visual plant of coal liquefaction industry MEK project, and it belongs to two class pressure vessels.The cylindrical shell of equipment, fillter section, adapter are forge piece, and end socket and conical shell are 16MnR plate, the OOCr17Ni14Mo2 of inside surfacing 5mm; Equipment internal diameter is 2400mm, and cylindrical shell is 120mm by wall thickness, and the two joint cylindrical shells of 140mm form.Conical shell thickness is 100mm, and equipment height overall is 7520mm, and weight is 54810Kg.The processing request of conical shell is saved material, and compacting is convenient, ensures the quality of products, and technical difficulty is very large, adopts conventional processing method to meet to save material, easy to process, the specification requirement that guarantees two class pressure.
Summary of the invention
The object of the invention is to overcome above-mentioned technical deficiency, provide that a kind of that conical shell is made to many lobes is compressing, a kind of coal dust reaction lock hopper of then manufacturing through assembly welding and Non-Destructive Testing.
The technical scheme that the utility model technical solution problem adopts is: a kind of coal dust reaction lock hopper, comprise cylindrical shell, changeover portion, upper connecting tube flange and lower linking tube flange, and it is characterized in that welding a conical shell between changeover portion and lower linking tube flange; Conical shell is by adopting the distinguish weld seam of assembly welding to be fixed together between distinguish, left split and right split in the middle of a plurality of.
The beneficial effects of the utility model are: this utility model is saved material, easy to process, has guaranteed quality requirement.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, with embodiment, illustrate.
Fig. 1 is a kind of main pseudosection of coal dust reaction lock hopper.
In figure: 1-cylindrical shell; 2-end socket; 3-upper connecting tube flange; 4-pipe connecting flange three; 5-pipe connecting flange two; 6-lower linking tube flange; 7-conical shell; 7-1-left split; Distinguish in the middle of 7-2-; 7-3-right split; 7-4-distinguish weld seam; 8-changeover portion; 9-pipe connecting flange four; 10-pipe connecting flange one.
The specific embodiment
Embodiment, with reference to accompanying drawing, a kind of coal dust reaction lock hopper, comprises cylindrical shell 1, changeover portion 8, upper connecting tube flange 3 and lower linking tube flange 6, it is characterized in that welding a conical shell 7 between changeover portion 8 and lower linking tube flange 6; Conical shell 7 is by adopting the distinguish weld seam 7-4 of assembly welding to be fixed together between four middle distinguish 7-2, left split 7-1 and right split 7-3.Cylindrical shell 1 upper end welding end socket 2 is welded with upper connecting tube flange 3 and two pipe connecting flanges 34 on end socket 2; On the right side wall of cylindrical shell 1, weld a pipe connecting flange 25, on left side wall, be welded with pipe connecting flange 1 and pipe connecting flange 49; A lower linking tube flange 6 of lower end welding of conical shell 7.
When processing conical shell 7, first that six distinguish are compressing, then pass through assembly welding and Non-Destructive Testing, guarantee product quality and solved a process technology difficult problem.
