Description
Technical field
This utility model is related to a kind of coal dust feeding system with swinging delivery pipe, is particularly well-suited to high-efficiency pulverized coal work
Industry boiler.
Background technology
German Industrial pulverized-coal fired boiler, with its safety, the feature of environmental protection（Exhaust emissions and generating plant pulverized coal boiler, gas fired-boiler phase
When）, advanced（Automatic measuring and controlling, teletransmission manipulation, unmanned）, economy（Efficiency of combustion more than 98%, boiler thermal output up to
More than 92%）, can be the succedaneum of oil and gas as clean energy resource.The small and medium-sized industrial coal powder boilers of China use for reference Germany
The technology of industrial coal powder boiler and theory, last 10 years, key core technology as coal dust tower, feed, have in combustion system
Broken through.
Chinese patent literature CN201458346U discloses a kind of pulse-free coal powder supply device, can effectively solving coal dust exist
The phenomenon compensating is piled up, blocks and conveyed to coal chute in road.But also bring another question, due to helical blade
Cannot avoid there is gap and duff pipe between, because spiral transferring tube cell bottom is provided with coal dust mixing injector, in pulverized coal flow
Thread a pipe interior formation negative pressure it is difficult to control charging rate, excessive coal dust is poured into burner hearth and formed detonation.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of swinging that carries to convey for above-mentioned prior art
The feeding system of pipe, it may ensure that the stable material-supplying of coal dust.
The technical scheme in the invention for solving the above technical problem is：A kind of feed system with swinging delivery pipe
System, it includes feed bin, first level pipe and the second horizontal tube being sequentially arranged from top to bottom, described first level pipe left end setting
There is roots blower, be connected by bridge piece between described first level pipe right-hand member and the second horizontal tube right-hand member, described first
It is provided with Venturi in horizontal tube, be connected by material blanking tube between described bin bottom and Venturi.
Described feeding system also includes spiral conveying pipeline, and described spiral conveying pipeline is provided with charging near the upside of one end
Mouthful, the downside of the other end is provided with discharging opening, described bin bottom is connected with charging aperture, described discharging opening and material blanking tube
It is connected.
Described material blanking tube top half is vertical section, and the latter half is tilting section, the tilting section of described material blanking tube and level
The angle of line is 40 ° ~ 80 °.
It is provided with blowing pipe, the position of described blowing pipe is corresponding with the position of charging aperture on the downside of described spiral conveying pipeline.
It is provided with respiratory organ, the position of described respiratory organ is corresponding with the position of discharging opening on the upside of described spiral conveying pipeline.
Compared with prior art, the utility model has the advantage of：
1st, coal dust blanking is smooth, stable, no block, and no piles up；
2nd, coal dust feed is stable, controlled, will not cause because pouring into burner for a large amount of coal dust of local decompression in powder pipeline
Detonation.
Brief description
Fig. 1 is a kind of structural representation of the feeding system with swinging delivery pipe of this utility model.
Wherein：
Roots blower 1
First level pipe 2
Second horizontal tube 3
Venturi 4
Bridge piece 5
Feed bin 6
Spiral conveying pipeline 7
Respiratory organ 8
Material blanking tube 9
Blowing pipe 10.
Specific embodiment
Below in conjunction with accompanying drawing embodiment, this utility model is described in further detail.
As shown in figure 1, one of the present embodiment carry swinging delivery pipe feeding system, it include from top to bottom according to
The feed bin 6 of secondary arrangement, first level pipe 2 and the second horizontal tube 3, described first level pipe 2 left end is provided with roots blower 1, institute
State and be connected by bridge piece 5 between first level pipe 2 right-hand member and the second horizontal tube 3 right-hand member, described second horizontal tube 3 left end
Connecting pipe accesses boiler-burner, is provided with Venturi 4, described feed bin 6 bottom and Wen Qiu in described first level pipe 2
In be connected by material blanking tube 9 between device 4, roots blower wind out forms high-speed jet through Venturi, carries
Expects pipe fall coal dust after formed wind powder mixture, enter bridge piece, through 180 ° turn to after reduction of speed, all flow after wind powder gas
Stream, enters boiler-burner through conveyance conduit.
Described material blanking tube 9 top half is vertical section, and the latter half is tilting section, the tilting section of described material blanking tube 9 and water
The angle of horizontal line is 40 ° ~ 80 °, and this angle is more than the angle of repose of coal dust；
The coal dust of material blanking tube 9 lower port is fallen due to deadweight, and the Venturi 4 of its underpart produces ejector action simultaneously,
Producing negative pressure in ash dropping hopper accelerates coal dust to flow downward, and the wind that coal dust is conveyed with roots blower forms wind powder mixture warp after mixing
Boiler is entered after all stream of bridge piece 5, deceleration after crossing Venturi 4；Bridge piece 5 is 180 ° of bend pipes, and it is permissible
Wind powder mixture after buffering Venturi 4, prevents wind powder mixture from entering boiler with too high speed；
Described feeding system also includes spiral conveying pipeline 7, and described spiral conveying pipeline 7 is provided with charging near the upside of one end
Mouthful, the downside of the other end is provided with discharging opening, described feed bin 6 bottom is connected with charging aperture, described discharging opening and blanking
Pipe 9 is connected；
It is provided with blowing pipe 10, the position of described blowing pipe 10 and the position phase of charging aperture on the downside of described spiral conveying pipeline 7
Corresponding, ensure that discharging is not lumpd, do not block；
It is provided with respiratory organ 8, the position of described respiratory organ 8 is relative with the position of discharging opening on the upside of described spiral conveying pipeline 7
Should, the pressure in spiral conveying pipeline can be made to keep basically identical with external atmosphere pressure, thus realizing stable material-supplying.
In addition to the implementation, this utility model also includes other embodiment, all employing equivalents or equivalent
The technical scheme that substitute mode is formed, all should fall within this utility model scope of the claims.
