Abstract
The utility model discloses a quick-opening overhaul door of a slag well for a coal-fired boiler, comprising an overhaul door cover and an overhaul door outer cover plate which are rotatably connected through two groups of connecting rods formed by rotatable connection of a connecting rod 1 and a connecting rod 2; and the overhaul door cover is in threaded connection with compression bolts fixed on the overhaul door outer cover plate through a fixed hand wheel so as to lead the overhaul door cover plate to be tightly adhered to the overhaul door outer cover plate. With the quick-opening overhaul door, overhaul personal can easily open and close the overhaul door, so that the overhaul efficiency of overhaul personal can be improved.
Description
Technical field
The utility model relates to coal-burning boiler slag well technical field, relates in particular to a kind of fast-open type access door of coal-burning boiler slag well.
Background technology
The access door of coal-burning boiler is relatively heavier at present, switch maintenance door inconvenience when causing overhauling, and labor intensive influences overhaul efficiency.
The utility model content
The purpose of this utility model is at the deficiencies in the prior art, and a kind of fast-open type access door of coal-burning boiler slag well is provided, and the utility model can reduce maintainer's workload, improves overhaul efficiency.
The technical solution adopted in the utility model is: a kind of fast-open type access door of coal-burning boiler slag well, the fast-open type access door includes the access door door closure of square and at the access door outer cover plate that has the inclination angle away from access door door closure side, access door door closure outside symmetric arrangement has the access door handle, disposed inboard has the thick insulation material of 200～500mm, the access door outer cover plate is outer surface center and fixing a hold-down bolt respectively near the end face of access door cover plate up and down, two fixedly handwheel respectively with pass the access door outer cover plate on the hold-down bolt in U type hole be threaded; The link assembly that two groups of connecting rods one that are rotationally connected by connecting bolt and connecting rod two are formed is rotationally connected with access door outer cover plate and access door door closure by the place, two ends up and down of connecting bolt in the same side of access door outer cover plate and access door door closure respectively.
Further, described hold-down bolt can be done 180 ° of rotations; The inclination angle of described access door outer cover plate is 45～60 °.
The beneficial effect that the utlity model has is:
1. fixedly handwheel can make access door door closure and access door outer cover plate fully fit, and reduces the boiler inleakage.
2. the insulation material of maintenance door closure disposed inboard can effectively intercept the heat radiation in the slag well, makes the fast-open type access door remain on normal temperature.
3. the connecting rod connected mode of access door door closure and access door outer cover plate can make access door be easy to open and close.
4. the utility model compact conformation is easy to loading and unloading, the versatility height, and it is aboveground directly to be contained in various boiler slag.
5. the utility model is used for thermal power plant coal-burning boiler slag well, and is extensive in sector applications such as metallurgy, electric power, chemical industry.
