In pipeline, prevent the transition scraper chain of zanjon jam
Technical field
The utility model relates to a kind of chain.
Background technology
In the technical field that at present titanium is smelted, magnesium metal displaces Titanium as reducing agent from TiCl4, so the production of the magnesium link that is absolutely necessary.Current electrolysis magnesium is a common method of producing magnesium, the process of electrolytic magnesium is to carry out in closing down magnesium electrolysis bath, in this process, will produce a large amount of electrolysis flue gas Zhao sublimates, sublimate will be by a series of flue collection and treatments, but the sublimate in the flue gas can deposit and attached to the flue inwall, remove so need scraper plate be set in flue.
Flue length is bigger; long at present flue length reaches 70 ~ 80 meters; circular flue will be made up of the flanged (FLGD) pipeline in more piece two; the hook bank that the welding of flange and steel pipe itself has Welding Structure to stay; be lined with certain thickness sealing gasket between the flange; if consider insulation system in some joint; the furrow width that produces in this joint can reach more than the 30mm; the degree of depth reaches the thickness (can reach 28mm) of steel pipe; scraper plate will pass through these ditches smoothly in pipeline; the thickness of scraper plate just need design very greatly; otherwise scraper plate will be stuck in the inside by these ditches the time; this just might break chain, perhaps causes serious overload to shut down, and what influence was produced normally carries out.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of transition scraper chain that prevents the zanjon jam in pipeline is provided, to guarantee in flue inner wall cleaning operate as normal in service, overcomes the deficiencies such as chain jamming that prior art exists.
The utility model is to constitute like this: it comprises standard link, and scraper plate is arranged on standard link, and the transition guide pad is arranged on scraper plate.
Standard link and scraper plate, scraper plate and transition guide pad are for being welded to connect.
The utility model compared with prior art, on each scraper plate, embed three transition guide pads, can guarantee that scraper plate moves to pipe joint place and do not blocked by wide ditch in pipeline, can carry out the removing of sublimate in the whole pipe smoothly, guarantee in flue inner wall cleaning operate as normal in service.

The specific embodiment
Embodiment of the present utility model: make the loop chain of good design on request, welding scraper plate 2 on the chain link 1 of loop chain, welding transition guide pad 3 on scraper plate 2.By designing requirement, make the scraper plate 2 of arc, its radian, width, thickness etc. determine that according to the pipe design structure each scraper plate 2 has 3 transition guide pads 3, the scraper plate 2 that will have transition guide pad 3 is welded on the chain link 1 every certain distance by designing requirement.The physical dimension of transition guide pad 3 is determined according to the dimensional structure of width of striding ditch and scraper plate 2, the scraper plate that several (quantity is determined according to needs such as cleaning effects) band transition guide pads are arranged on the whole piece loop chain after making, it is the transition scraper chain, it is installed on the sprocket wheel of pipe ends, by machine driving, by the rotation of driven by motor sprocket wheel, thus even running in whole pipe, remove ducted sublimate, unblocked to guarantee flue.
