Abstract
The utility model relates to a fluidized bed boiler deslagging pipe capable of realizing dredging without shutdown, which belongs to the technical field of fluidized bed boiler deslagging pipe equipment and is used for dredging the fluidized bed boiler deslagging pipe. The technical scheme is as follows: the fluidized bed boiler deslagging pipe comprises a deslagging pipe, a dredging rod, a cross rod and an operating handle, wherein the dredging rod is arranged in the deslagging pipe along the axial direction of the deslagging pipe; the side wall of the deslagging pipe is provided with a slotted hole along the axial direction of the deslagging pipe; one end of the cross rod is vertically connected with the dredging rod, and the other end of the cross rod extends out of the slotted hole; and the operating handle is connected to the outer end of the cross rod. According to the utility model, the dredging rod is arranged in the deslagging pipe, so that operating personnel can control the dredging rod to move up and down through the slotted hole in the side wall of the deslagging pipe, thereby ensuring that slag blocks in the deslagging pipe can be displaced and loosened, and further dredging the deslagging pipe. The fluidized bed boiler deslagging pipe provided by the utility model is simple in structure, convenient to use and favorable in dredging effect, can realize dredging of the deslagging pipe without shutdown, avoids the problem that a boiler can not operate normally due to blockage of the deslagging pipe, and has obvious economic benefits.
Description
Technical field
The utility model relates to a kind of fluidized-bed combustion boiler slag-discharge pipe that can dredge under not blowing out state, belongs to fluidized-bed combustion boiler slag-discharge pipe equipment technical field.
Background technology
Fluid-bed boiler slagging mode mostly is bottom slagging at present, join two barrel slag coolers, each slag-discharge pipe that is 159mm * 5mm rare-earth and high chromium nickel nitrogen heat resisting cast steel by a diameter passes air compartment and is connected with air distribution plate, during normal operation, one time wind enters air distribution plate fluid bed from air compartment, unnecessary bed material enters barrel slag cooler by 159mm * 5mm rare-earth and high chromium nickel nitrogen heat resisting cast steel slag-discharge pipe, is progressively cooled and solidifies, and falling into slag-draining device.In fluidized-bed combustion boiler slag-discharge pipe in service, slagging scorification obstruction is comparatively common multiple accident, when there is slag-discharge pipe obstruction, if can not drain increasing gradually after-flame lime-ash on fluid bed bed surface in time, will cause boiler can not normally move even blowing out.
Utility model content
Technical problem to be solved in the utility model be to provide a kind of can not blowing out the fluidized-bed combustion boiler slag-discharge pipe of dredging, this slag-discharge pipe can be dredged the in the situation that of not blowing out, prevents to stop up because of slag-discharge pipe the problem that the boiler cause can not normally move.
The technical scheme solving the problems of the technologies described above is:
A kind of can not blowing out the fluidized-bed combustion boiler slag-discharge pipe of dredging, it comprises slag-discharge pipe, dredging bar, cross bar, operating grip, dredging bar is stock, dredging bar being axially placed in slag-discharge pipe along slag-discharge pipe, on the sidewall of slag-discharge pipe, have along the axial slotted eye of slag-discharge pipe, bar is vertical is connected with dredging in one end of cross bar, and the other end of cross bar stretches out the slotted eye on slag-discharge pipe sidewall, and operating grip is connected to the outer end of cross bar.
Above-mentioned can not blowing out the fluidized-bed combustion boiler slag-discharge pipe of dredging, the front end of described dredging bar is provided with sharp-pointed rifle head, rifle head is relative with blast cap direction.
Above-mentioned can not blowing out the fluidized-bed combustion boiler slag-discharge pipe of dredging, on described cross bar, be connected with baffle plate, baffle plate is along the length direction of slag-discharge pipe, baffle plate covers on the slotted eye of slag-discharge pipe sidewall.
Above-mentioned can not blowing out the fluidized-bed combustion boiler slag-discharge pipe of dredging, the slotted eye upper end anomaly platform 1.3m to 1.5m on described slag-discharge pipe sidewall.
The beneficial effects of the utility model are:
The utility model is placed dredging bar in slag-discharge pipe, and operating personnel can handle dredging bar by the slotted eye on slag-discharge pipe sidewall and move up and down, and dredging bar can be subjected to displacement looseningly by being blocked in clinker in slag-discharge pipe, and slag-discharge pipe is dredged.The utility model is simple in structure, easy to use, it is respond well to dredge, and can the in the situation that of not blowing out, to slag-discharge pipe, dredge, and prevents, because slag-discharge pipe stops up the problem that the boiler that causes can not normally move, to have significant economic benefit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, each label is: blast cap 1, air distribution plate 2, rifle head 3, dredging bar 4, cross bar 5, operating grip 6, slotted eye 7, slag-discharge pipe 8, slag cooler 9, baffle plate 10, clinker 11, air compartment 12.
The specific embodiment
The utility model is comprised of slag-discharge pipe 8, dredging bar 4, cross bar 5, operating grip 6, baffle plate 10.
In figure, show, blast cap 1 is welded on air distribution plate 2, and slag-discharge pipe 8 passes at air distribution plate 2, and slag-discharge pipe 8 lower ends are connected with slag cooler 9, has along the axial slotted eye 7 of slag-discharge pipe 8 slotted eye 7 upper end anomaly platform 1.3m to 1.5m on the sidewall of slag-discharge pipe 8.
In figure, show, dredging bar 4 is long tube, dredging bar 4 being axially placed in slag-discharge pipe 8 along slag-discharge pipe 8, bar 4 is vertical is connected with dredging in one end of cross bar 5, the other end of cross bar 5 stretches out the slotted eye 7 on slag-discharge pipe 8 sidewalls, operating grip 6 is connected to the outer end of cross bar 5, and the front end of dredging bar 4 is provided with sharp-pointed rifle head 3, and rifle head 3 is relative with blast cap 1 direction.Operating personnel hold operating grip 6 outside slag-discharge pipe 8 can make cross bar 5 move forward and backward along slotted eye 7, thereby has movement before driving dredging bar 4.
