The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail:
In the drawings, described housing arranges frame 21 time, the interior connection metering of described housing 1 frame 13; One end of described metering frame 13 connects driving wheel 4, and the other end connects flower wheel 5; Described driving wheel 4 is connected with motor 3; Described annular carrier bar 6 is enclosed within on the outer rim of driving wheel 4 and flower wheel 5; The centre of described driving wheel 4 and flower wheel 5 arranges one or more bearing support 12; The top of the outside face of described bearing support 12 contacts with the lower surface on the top of annular carrier bar 6; Described metering frame 13 is connected with LOAD CELLS 14; Described LOAD CELLS 14 is connected with control instrument 17 by signal wire (SW) 16; Rotating shaft place of described motor 3 arranges speed sensor 15; Described speed sensor 15 is connected with control instrument 17 by signal wire (SW) 16; Described control instrument 17 is connected with frequency converter 11 by signal wire (SW) 16, and is connected with electrical control cabinet 10 by wire 9; The input end of described frequency converter 11 is connected with electrical control cabinet 10 by wire 9, and mouth is connected with motor 3 by wire 9; One end of described housing 1 arranges coal inlet 7, and the other end arranges coal outlet 8.
The material of described annular carrier bar is metal, makes for steel plate in the utility model.
When the utility model needs work, open electrical control cabinet 10, motor 3 entrys into service, annular carrier bar 6 moves under the effect of driving wheel 4.Fire coal is fallen on annular carrier bar 6 from coal inlet 7, in operational process, coal-fired to metering frame 13 generation application forces, this masterpiece is used for being connected to the LOAD CELLS 14 on metering frame 13, thereby produce a voltage signal that is proportional to load (fire coal), this voltage signal is sent into control instrument 17 through signal wire (SW) 16, control instrument 17 receives the impulse singla that is transmitted by signal wire (SW) 16 by speed sensor 15 simultaneously, control instrument 17 draws instant flow rate value and cumulative flow value by weight signal and speed signal are carried out the integral operation processing.17 pairs of these flows of control instrument compare with the setting flow, and feedback signal is controlled frequency converter 11, frequency converter 11 is worked according to the signal of control instrument 17 feedbacks, the synchronization of motor 3 is changed, thereby coal-fired flow is changed, approach and remain on the coal supply flow that sets.Owing to can adjust timely coal-supplying amount, thereby realized quantitatively, the even purpose of coal supply, satisfied operating needs.
The setting of bearing support 12 has guaranteed the smooth running of annular carrier bar 6.Because the material of annular carrier bar 6 is that steel plate is made, thus when running to the high temperature place, be difficult for occuring the peculiar phenomenon such as aging of endless rubber belt, thus guaranteed the reliability service of boiler.
