Abstract
The disclosed specific air-lancing rotary feed arrangement sealed by air and pressure includes shell body with feed inlet and discharge port, rotator, major axis, and drive unit. Characters are that the arrangement also includes air distributor and sealed wind connection tube; being installed inside the shell body, rotator connected to the major axis is composed of body of rotator with hollow structure, and 3-12 pieces of case fixed on surface of rotator; air distributor is setup inside rotator, and vent hole is setup on surface of rotator; radial outer ends and two end faces of cases are connected to gap of inner wall of shell body and the tube; outer end of air distributor is connected to the tube. The arrangement also can be in use as system equipment for deslagging and fishing for dregs on bottom of boiler. Advantages are: insulating system of feeding coal from fume in high temperature so as to prevent accidents caused by walloping fume, simple structure, and not leak etc.
Description
Technical field the present invention relates to the charging gear of a kind of CFBB coal supply system in energy project field, a kind of specifically air force seal blowing rotary feeder; This device also can be used as the slagging-off of boiler furnace bottom, drags for slag equipment.
The bunker coal of the required usefulness of the present CFBB of background technology exists in the coal bunker, input to coal supply system before the boiler from coal bunker again, coal supply system equipment is nearer apart from boiler high temperature burning emulsion zone and siege, when the boiler operatiopn working conditions change, when burner hearth occurring and emitting malleation, the high-temperature flue gas anti-channeling will often take place burn out the production accident of feeder belt and other parts in coal supply system and coal bunker, even the serious accident of coal supply system blast can take place.In addition, charging gear is prone to problems such as leakage, sizing, jam, has a strong impact on the safe operation of station boiler.
Summary of the invention the objective of the invention is to solve the deficiencies in the prior art, a kind of air force seal blowing rotary feeder is provided, this device can be isolated the high-temperature flue gas of CFBB coal supply system and boiler furnace generation, avoid the anti-channeling of high-temperature flue gas and cause various accidents, this apparatus structure is simple, easy to operate, do not leak, sizing not.
In order to realize described purpose, the technical solution used in the present invention is as follows: a kind of air force seal blowing rotary feeder comprises the housing, rotor, main shaft, the drive unit that are provided with charging aperture and discharging opening; It is characterized in that: it also is provided with air distributor and sealing wind is taken over; The rotor that is connected with main shaft is installed in the housing, and rotor is by the hollow structure rotor block and be fixed on lip-deep 3～12 the storehouse lattice of rotor block and form, and is provided with air distributor in the rotor block, and the rotor block surface is provided with air vent; The radial outer end of storehouse lattice and both ends of the surface are taken over sealing wind with the gap of housing madial wall and are communicated; The air distributor outer end connects sealing wind and takes over.
Adopt technique scheme, drive the rotor rotation by drive unit, the fire coal that utilizes rotor storehouse grid space volume that charging aperture is fallen into is transferred to discharging opening continuously, evenly, hermetically and is fallen into burner hearth.Thereby can effectively prevent high-temperature flue gas from the discharging opening anti-channeling to charging aperture, with protection coal supply equipment and belt, guarantee safe operation of the boiler; Take over rotor block inner chamber and the outer wall place of being association of activity and inertia because of the sealing wind on the rotor block and to communicate, the place of being association of activity and inertia inner to rotor block and transmission mechanism carries air, prevents that on the one hand the lattice generation of rotor storehouse from gluing coal, prevents that simultaneously coal dust from entering the transmission place of being association of activity and inertia.
Description of drawings Fig. 1 is the front view of air force seal blowing rotary feeder,
