Abstract
The utility model discloses a novel unblocking measurement and control system for a stokehole, and the system mainly consists of a coal-bunker automatic unblocking device, a totally-closed weighing coal feeder, and an electrical appliance control system. The coal-bunker automatic unblocking device comprises a raw coal bunker, a coal-bunker unblocking device fixed on an inner side surface of the raw coal bunker, a charging coal-falling tube connected to the lower end opening of the raw coal bunker, an adjustable connector connected with the coal-bunker automatic unblocking device and the totally-closed weighing coal feeder, and an inlet automatic gate connected with the charging coal-falling tube and the adjustable connector. The electrical appliance control system comprises an unblocking device control box connected with the coal-bunker automatic unblocking device, and also comprises a coal feeder control box connected with the totally-closed weighing coal feeder. The system provided by the utility model solves a problem of blocking and stacking of coal in a coal bunker of the stokehole, and can be used for the stokeholes of a circulating fluid bed boiler, a pulverized coal furnace, and the like.
Description
Technical field
The utility model relates to a kind of stokehold block clearing TT&C system, is specially the front block clearing TT&C system of a kind of Novel furnace.
Background technology
Ensureing and continuous operation safe and reliable into coal stove, is the condition precedent of guaranteeing normal operation of boiler, and stokehold coal bunker is because coal is stifled or canopy coal and the operation of defeated device for coal unstable, may cause boiler non-normal working.
Utility model content
The utility model, according to above-mentioned the deficiencies in the prior art, provides a kind of Novel furnace front block clearing TT&C system.
In order to achieve the above object, the technical scheme that the utility model is taked is:
Block clearing TT&C system before a kind of Novel furnace, mainly formed by coal bunker automatic block clearing device, totally-enclosed Gravimetric Coal Feeders and electrical apparatus control system, described coal bunker automatic block clearing device comprise run coal bin, fixed in position the coal bunker dredging device of run coal bin medial surface, be connected to run coal bin lower port charging coal spout, connect the adjustable connector and the import self-shooter that is connected charging coal spout and adjustable connector of coal bunker automatic block clearing device and totally-enclosed Gravimetric Coal Feeders; Electrical apparatus control system comprises the dredge control box and the feeder control box that is connected totally-enclosed Gravimetric Coal Feeders that connect coal bunker automatic block clearing device.
In described dredge control box, be mounted with hydraulic efficiency pressure system, hydraulic efficiency pressure system connects coal bunker dredging device.
Described electrical apparatus control system also includes DCS system.
Described totally-enclosed Gravimetric Coal Feeders is a kind of withstand voltage totally-enclosed feeder of weighing.
The beneficial effects of the utility model are: the utility model has solved the problem of chute blockage or the canopy coal of stokehold coal bunker, can be used on before the Boiler Furnace such as circulating fluidized bed boiler, coal-powder boiler.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is electrical apparatus control system schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is illustrated.
As depicted in figs. 1 and 2, the utility model is block clearing TT&C system before a kind of Novel furnace, mainly formed by coal bunker automatic block clearing device, totally-enclosed Gravimetric Coal Feeders and electrical apparatus control system, described coal bunker automatic block clearing device comprise run coal bin 1, fixed in position the coal bunker dredging device 2 of run coal bin 1 medial surface, be connected to run coal bin 1 lower port charging coal spout 3, connect the adjustable connector 4 of coal bunker automatic block clearing device and totally-enclosed Gravimetric Coal Feeders and be connected the import self-shooter 5 of charging coal spout 3 and adjustable connector 4; Electrical apparatus control system comprises the dredge control box 6 and the feeder control box 7 that is connected totally-enclosed Gravimetric Coal Feeders that connect coal bunker automatic block clearing device.In dredge control box 6, be mounted with hydraulic efficiency pressure system, hydraulic efficiency pressure system connects coal bunker dredging device 2.Electrical apparatus control system also includes DCS system.Totally-enclosed Gravimetric Coal Feeders is a kind of withstand voltage totally-enclosed feeder of weighing.
Adopt the coal bunker dredging device 2 of HYDRAULIC CONTROL SYSTEM run coal bin 1 inwall along the upper and lower straight-line motion of inwall, coal is loose, when the disconnected coal of totally-enclosed Gravimetric Coal Feeders or chute blockage, connect limit switch, send electrical instruction, after loose, coal drops on belt, and machine ringing is interrupted, loose end cycle.
Such scheme is preferred embodiment of the utility model, but is not changing under spiritual background of the present utility model, and any improvement of doing, within all dropping on protection domain of the present utility model.
