Abstract
The utility model discloses a drawable sleeve structure which comprises a first flange (1) and a material inlet and outlet pipe (2), wherein the first flange (1) is fixed at an outlet at the top end of the material inlet and outlet pipe (2), a flat cover (3) is fixed in the middle of the material inlet and outlet pipe (2), a device body (7) is fixed at the lower end of a connecting pipe (6), the upper end of the connecting pipe (6) is fixed with a second flange (5), and the second flange (5) is connected with the flat cover (3). According to the technical scheme, the material inlet and outlet pipe can be taken out as a whole during replacement, local heat treatment does not need to be performed on a device, and the material inlet and outlet pipe (2) can be rapidly replaced, thereby saving manpower and physical resources and improving production efficiency.
Description
Technical field
The utility model relates to a kind of pressurized container, relates in particular to a kind of drawing out type sleeve structure.
Background technique
In chemical process, can use a lot of pressurized containers, pressurized container must have the turnover of splendid attire thing, because washing away of material, the tube wall of pressurized container feed and exhaust tube can just must be changed this pipe when tube wall is ground to a certain degree in use by wear down, otherwise, because tube wall is thin excessively, will stays potential safety hazard even security incident takes place.At present, the structural type of existing pressurized container feed and exhaust tube all is to adopt feed and exhaust tube and apparatus body welding, this structure, when tube wall need be changed by wear down, then need the weld seam excision, make the welding of a steel pipe and apparatus body again and this weld seam heat-treated after can come into operation, and heat treatment needs the relatively time of length, can can not use the huge waste that causes manpower and materials for a long time because of equipment like this, and reduce work manufacturing efficiency.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of and feed and exhaust tube integral body can be taken out when changing, need not carry out diffusion zone to equipment again, the drawing out type sleeve structure that uses manpower and material resources sparingly, enhances productivity is to overcome the deficiencies in the prior art.
In order to solve the problems of the technologies described above, the utility model has been taked following technological scheme:
A kind of drawing out type sleeve structure comprises first flange and feed and exhaust tube, and first flange is fixed on the outlet port, top of feed and exhaust tube, flat cover is fixed on the feed and exhaust tube middle part, take over lower end and apparatus body and fix, the upper end and second flange are fixed, and second flange is connected with flat cover.
According to the technical solution of the utility model, when feed and exhaust tube need change, only need the connecting bolt between second flange and the flat cover is pulled down, take out the feed and exhaust tube that needs replacing, in the new feed and exhaust tube that will make then injects and takes over,, the bolt and nut of pulling down is tightened got final product again good bolt hole position, need not to heat-treat when mounted again, saved manpower and materials.
Description of drawings
Fig. 1 is the structural representation of a kind of drawing out type sleeve structure of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.
Embodiment
As shown in Figure 1, first flange 1 is welded on the top exit place of feed and exhaust tube 2, flat cover 3 is welded on the feed and exhaust tube middle part, flat cover 3 can be according to the needs adjustment of the feed inlet and outlet height of feed and exhaust tube 2 in the welding position of feed and exhaust tube, apparatus body 7 is welded on takes over 6 lower end, takes over 6 upper ends and 5 welding of second flange, and convenience is connected with feed and exhaust tube, second flange 5 is fixedlyed connected with flat cover 3 by bolt, is lined with big pad 4 between second flange 5 and the flat cover 3.When feed and exhaust tube 2 need be changed by wear down, only need the bolt 8, minipad 9 and the nut 10 that connect second flange 5 and flat cover 3 are pulled down, take off the feed and exhaust tube 2 of wearing and tearing, replace with new feed and exhaust tube 2, loading onto bolt can normally use, the heat treatment process that need carry out when having avoided direct the welding has been saved human and material resources, has improved manufacturing efficiency.
In a word, the above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
