The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail:
In Fig. 1 or Fig. 4, an end of described casing 1 arranges coal feed point 8, and the other end arranges coal outlet 9, the outer setting frame 2 of casing 1, and an end of frame 2 arranges main motor 3, and the other end arranges driven pulley 5; Main motor 3 is connected with driving wheel 4, and driving wheel 4, driven pulley 5 are connected with ring chain 6 respectively, and one or more scraper plate 7 is set on ring chain 6, and main motor 3 is connected with wire 10, and wire 10 is connected with electrical control cabinet 11; Weighing device 12 is connected with coal feed point 8, and its electric part is connected with electrical control cabinet 11 by wire 10.
In Fig. 2 or Fig. 4, described weighing device 12 comprises variable-frequency motor 13, frequency converter 14, metering frame 15, LOAD CELLS 16, velocity sensor 17, holding wire 18, control instrument 19, claims body 20.Described variable-frequency motor 13 is connected with title body 20; One end of described title body 20 is connected with metering frame 15, and the other end is connected with LOAD CELLS 16 more than one or one; Described LOAD CELLS 16 is connected with holding wire 18; Described velocity sensor 17 is connected with holding wire 18; Described holding wire 18 is connected with control instrument 19; Described control instrument 19 is connected with frequency converter 14 by holding wire 18, is connected with electrical control cabinet 11 by wire 10; The input of described frequency converter 14 is connected with electrical control cabinet 11 by wire 10, and output is connected with variable-frequency motor 13 by wire 10.
In Fig. 3, described title body 20, comprise charging aperture 21, discharging opening 22, cylindrical shell 23, helical axis 24, helical blade 25, one end of described cylindrical shell 23 is provided with charging aperture 21, the other end is provided with 22, in described cylindrical shell 23, helical axis 24 is housed, one or more helical blade 25 is housed on described helical axis 24.
When the utility model needs work, open electrical control cabinet 11, the main motor 3 that arranges on frame 2 brings into operation, and ring chain 6 drives scraper plate 7 in the interior motion of casing 1 under the effect of driving wheel 4.Coal-fired enters in weighing device 12 from coal feed point 8, and this moment, weighing device 12 was started working, and measured., enter in boiler through coal outlet 9 equably and fully burn under the effect of scraper plate 7 through the fire coal after Weighing.
Fallen into by coal feed point 8 when fire coal in the title body 20 that charging aperture 21 enters weighing device 12, under the effect of variable-frequency motor 13, helical axis 24 rotations, thereby drive helical blade 25 run-in synchronisms, flow out when fire coal moves to discharging 22 in cylindrical shell 23, fall on frame 2, transport to coal outlet 9 by scraper plate 7.
