Abstract
The utility model discloses a circulation fluid bed boiler coal-feeding tube anti-blocking device, comprising a coal feeding tube (3) connected with a coal feeder outlet (1) and a hearth (2), a coal feeding tube anti-blocking hole (4) opened on the coal feeding tube (3), a cover plate connected with the coal feeding tube anti-blocking hole (4). The coal feeding tube anti-blocking hole is opened on the coal feeding tube and the cover plate is connected with the coal feeding tube anti-blocking hole, the operating personnel automatically opens the anti-blocking hole and timely processes the anti-blocking hole in no need of a repair personnel when the coal feeding tube is blocked, thus the processing time of the blocked coal feeding tube is shortened and the coal is continuously supplied to the boiler. The coal feeding tube anti-blocking hole is arranged at the corner of the coal feeding tube, because the blocking positions are always at the corners, thus the sundries are conveniently taken out to increase the cleaning speed. The cover plate is connected with the coal feeding tube anti-blocking hole by a quick bolt, thus the coal feeding tube anti-blocking hole is convenient opened and closed, furthermore the maintenance speed is increased.
Description
Technical field
The utility model relates to a kind of CFBB and broadcasts coal pipe anti-block apparatus, belongs to the CFBB technical field.
Background technology
In CFBB, feeder is exported to burner hearth, and to broadcast the coal pipeline section be hermetically sealed shape, install and design in processing method when also not considering to broadcast in the boiler operatiopn coal pipe and plugging occurring; In the recirculating fluidized bed actual moving process,, foreign material, coal cinder broadcast the coal pipe because of exporting to fall into from feeder, and cause the phenomenon of plugging to take place often, when this type of situation occurring, the operations staff can only broadcast the coal pipe and handles by beaing, and DeGrain, incured loss through delay the time of handling the disconnected coal of feeder, the safe operation that jeopardizes boiler.
The utility model content
The technical problems to be solved in the utility model is: broadcast coal pipe anti-block apparatus but provide a kind of easy cleaning to broadcast the CFBB that stops up foreign material in the coal pipe, can overcome the deficiencies in the prior art.
The technical solution of the utility model: it comprise connect feeder outlet and burner hearth broadcast the coal pipe,
Broadcast the anti-plug-hole of coal pipe and be positioned at the corner of broadcasting the coal pipe.
Cover plate by the fast-assembling bolt with broadcast the anti-plug-hole of coal pipe and be connected.
Compared with the prior art, the utility model is by broadcasting the anti-plug-hole of coal pipe broadcasting to offer on the coal pipe, be connected with cover plate broadcasting on the anti-plug-hole of coal pipe, ought occur like this broadcasting under the situation of coal pipe plug, the operations staff can open anti-plug-hole voluntarily and in time handle, need not maintainer's arrival by the time, shortened the processing time of broadcasting the coal pipe plug, guaranteed to the continuous coal supply of boiler.Broadcast the anti-plug-hole of coal pipe and be positioned at the corner of broadcasting the coal pipe,, can conveniently foreign material be pulled out like this, improve cleaning speed because of managing interior blocking position multidigit in corner.Cover plate by the fast-assembling bolt with broadcast the anti-plug-hole of coal pipe and be connected, so conveniently broadcast the open and close that the coal pipe is prevented plug-hole, further improve maintenance speed.
Figure of description
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Embodiment: as shown in Figure 1, broadcast coal pipe 3 and be responsible for being connected of feeders outlet 1 and burner hearth 2, utilize cutter the corner of broadcasting coal pipe 3 and easily obstruction place offer and broadcast the anti-plug-hole 4 of coal pipe, and connect cover plate broadcasting on the anti-plug-hole 4 of coal pipe, cover plate by the fast-assembling bolt with broadcast the coal pipe and prevent that plug-hole 4 is connected.
When the situation that coal pipe 3 stops up occurring broadcasting, the operations staff can open voluntarily and broadcast the anti-plug-hole 4 of coal pipe and in time handles, need not maintainer's arrival by the time, has shortened the processing time of broadcasting 3 obstructions of coal pipe, has guaranteed to the continuous coal supply of boiler after the transformation.
Claims (3)
1. a CFBB is broadcast coal pipe anti-block apparatus, it comprise connect feeder outlet (1) and burner hearth (2) broadcast coal pipe (3), it is characterized in that: broadcast the anti-plug-hole (4) of coal pipe broadcasting to offer on the coal pipe (3), be connected with cover plate broadcasting on the anti-plug-hole (4) of coal pipe.
