Abstract
The utility model relates to a sealing device at an inlet of a drum slag cooler. The sealing device comprises a slag inlet pipe of the slag cooler, wherein the upper part of the slag inlet pipe of the slag cooler is shaped like a funnel; the upper end of the funnel-shaped slag inlet pipe is connected with a lengthening pipe; a circular ring clapboard is arranged in the lengthening pipe; the lengthening pipe is filled completely through a high-density heat-resistant aluminum silicate fiber felt layer above the circular ring clapboard; a fastening cover plate is arranged at the upper end of the lengthening pipe and fixed on a fixing block on the outer wall of the lengthening pipe through fastening bolts; a boiler slag discharging pipe is arranged in the lengthening pipe; and the end opening of the boiler slag discharging pipe is positioned above the fastening cover plate. The sealing device is reasonable in structure design as well as ingenious and novel in conception, and can be used for completely avoiding the potential safety hazard caused by spraying slags at the joint of the lengthening pipe and the slag discharging pipe of the slag cooler to an operating worker, so as to lighten the working intensity of the operating worker. In addition, the sealing device realizes labor saving and time saving properties when being maintained, and is low in manufacturing cost. Thus, the sealing device provided by the utility model is suitable for large-scale popularization.
Description
technical field:
The utility model belongs to steam power plant's mechanical device, and what be specifically related to is the sealing device of a kind of barrel slag cooler porch.
background technology:
Slag-discharge pipe position due to CFBB, approach and overlap with the feedback outlet of material returning device, in service at boiler, when a large amount of circulating ash is back to burner hearth, because utilizing cold slag machine, boiler carries out continuous discharging slag, cause it when fluidisation completely, a part is just along with the slag of boiler emission enters in cold slag machine, because of its good fluidity, cause the blast of burner hearth inside from here to external leakage, cause a large amount of thin ashes being mingled with slag ejection, its temperature is up to 900 ℃, equipment and operating personnel have been formed to larger harm, and the personnel that also often cause scald.
utility model content:
In order to overcome the deficiency in background technology, the utility model provides the sealing device of a kind of barrel slag cooler porch, has mainly solved cold slag machine extension pipe and slag-discharge pipe interface spray slag and easily operations staff has been caused a difficult problem for potential safety hazard.
The utility model solves the technical scheme that its technical problem adopts: the sealing device of this barrel slag cooler porch, the slag feed pipe that comprises cold slag machine, it is characterized in that: the slag feed pipe top of cold slag machine is funnel-form, funnelform slag feed pipe upper end connects extension pipe, extension pipe inside is provided with annulus dividing plate, it is real that annulus dividing plate top will lengthen pipe close by the heat-resisting alumina silicate fibre carpet veneer of high density, extension pipe upper end is provided with fastening cover plate, and by fastening bolt, be fixed on the fixed block of outer wall of extension pipe, extension pipe inside is provided with boiler slag-discharge pipe, and the port position of boiler slag-discharge pipe is in fastening cover plate top.
Effect intentionally of the present utility model: reasonable in design, novelty is skillfully constructed, thoroughly stopped the potential safety hazard that cold slag machine extension pipe and slag-discharge pipe interface spray slag cause operations staff, alleviated operating personnel's labour intensity, and keep in repair time saving and energy saving, low cost of manufacture, is easy to large-scale promotion application.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
the specific embodiment:
With reference to Fig. 1, the sealing device of this barrel slag cooler porch, the slag feed pipe 8 that comprises cold slag machine, it is characterized in that: slag feed pipe 8 tops of cold slag machine are funnel-form 7, slag feed pipe 8 upper ends of funnel-form 7 connect extension pipe 4, extension pipe 4 inside are provided with annulus dividing plate 6, annulus dividing plate 6 can guarantee that extension pipe 4 does not affect the flexible up and down of extension pipe 4 after being radially expanded being heated, annulus dividing plate 6 tops are real by extension pipe 4 plugs by the heat-resisting alumina silicate fibre carpet veneer 5 of high density, extension pipe 4 upper ends are provided with fastening cover plate 3, and by fastening bolt 2, be fixed on the fixed block of outer wall of extension pipe 4, the position of fastening cover plate 3 can not affect the flexible up and down of extension pipe 4, extension pipe 4 inside are provided with boiler slag-discharge pipe 1, and the port position of boiler slag-discharge pipe 1 is in fastening cover plate 3 tops.Because boiler is when starting and stop transport, exist downwards and the dilation making progress, for guaranteeing its free expanding, the extension pipe of slag feed pipe 8 upper ends of cold slag machine can make it have enough expansion spaces.The utility model had both guaranteed the not crimson slag of boiler, thoroughly having stopped cold slag machine extension pipe 4 is hidden danger with the safety that slag-discharge pipe 1 interface spray slag causes operations staff, do not affect again the free wxpansion of slag feed pipe 8, alleviated operating personnel's labour intensity, reasonable in design, the novelty that is skillfully constructed, low cost of manufacture, is easy to large-scale promotion application.
