Abstract
A kind of boiler coal feeding meter comprises coal supply auger, motor is mechanically connected by the speed reducer coupling of reduction box and coal supply auger, optoelectronic induction baffle plate is provided with at speed reducer coupling, photoelectric counter is fixedly installed on speed reducer coupling side by support, interval is had between photoelectric counter and speed reducer coupling, optoelectronic induction baffle plate rotates together with speed reducer coupling, and optoelectronic induction baffle plate is close to photoelectric counter, and photoelectric counter starts counting.The utility model has the advantage of, adopt contactless metering, meter is not fragile, long service life.
Description
Technical field
The utility model relates to a kind of boiler coal feeding meter, particularly a kind of boiler coal feeding meter for heating paper pulp.
Background technology
The heat utilizing coal burning boiler to produce heats paper pulp, is conducive to industrial gas and produces paper chapter, if but coal consumption too much can be caused high to the amount of boiler coal supply, both contaminated environment, affect again company's benefit, if paper pulp heating-up temperature can be caused inadequate to boiler coal supply deficiency, affect the production of paper chapter.In order to accurately control to boiler coal supply amount, generally can set up mechanical shift fork counter on boiler coal feeding pipeline, be very easy to damage, often have loose contact, wearing and tearing cause counting inaccurate, average one month bad 2.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of contactless, non-damageable boiler coal feeding meter.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of boiler coal feeding meter comprises coal supply auger, motor is mechanically connected by the speed reducer coupling of reduction box and coal supply auger, optoelectronic induction baffle plate is provided with at speed reducer coupling, photoelectric counter is fixedly installed on speed reducer coupling side by support, interval is had between photoelectric counter and speed reducer coupling, optoelectronic induction baffle plate rotates together with speed reducer coupling, optoelectronic induction baffle plate is close to photoelectric counter, and photoelectric counter starts counting.
Further, coal supply auger is located on framework, and coal supply auger coal-feeding end is lower than coal exit.
All right, coal supply auger coal-feeding end with enter coal bunker and be communicated with.
All right, enter coal bunker outer wall and be provided with vibrator.
The utility model advantage is, photoelectric counter does not contact with optoelectronic induction baffle plate, by the number of times of recording light electric induction baffle plate by photoelectric counter, calculate the number of times that motor drives coal supply auger to rotate, coal supply auger rotates the quantity can adding coal to boiler at every turn, can be calculated by pre-trial.
Coal supply auger coal-feeding end, lower than coal exit, makes coal enter eminence from lower and goes out, make full use of the self gravitation of coal, eliminates the distance between coal cinder and coal cinder, meter coal supply meter is counted more accurate.
Coal supply auger coal-feeding end with enter coal bunker and be communicated with, coal is introduced into after coal bunker in advance, then enters coal supply auger, and guaranteeing has stable coal amount to enter coal supply auger, and that reduces the idle running of coal supply auger can property, improves coal supply meter counting more accurate.
Enter vibrator that coal bunker outer wall establishes by vibration, the possibility that coal cinder gets lodged in coal supply auger coal-feeding end can be reduced.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model preferred structure schematic diagram.
As figure, coal supply auger 1, motor 2, reduction box 3, speed reducer coupling 4, optoelectronic induction baffle plate 5, photoelectric counter 6, coal-feeding end 7, coal exit 8, enter coal bunker 9, vibrator 10.
Detailed description of the invention
As in Fig. 1, a kind of boiler coal feeding meter comprises coal supply auger 1, motor 2 is mechanically connected with coal supply auger 1 by the speed reducer coupling 4 of reduction box 3, optoelectronic induction baffle plate 5 is provided with at speed reducer coupling 4, photoelectric counter 6 is fixedly installed on speed reducer coupling 4 side by support, has interval between photoelectric counter 5 and speed reducer coupling 4, and optoelectronic induction baffle plate 5 rotates together with speed reducer coupling 4, optoelectronic induction baffle plate 5 is close to photoelectric counter 6, and photoelectric counter 6 starts counting; Coal supply auger 1 one end is coal-feeding end 7, one end is coal exit 8, coal-feeding end 7 with enter coal bunker 9 and be communicated with, coal exit 8 is communicated with boiler, enters coal bunker 9 outer wall and is provided with vibrator 10, and Vibration on Start-up device 10 can make to produce vibration into coal bunker 9, prevents coal to be stuck in coal-feeding end 7 place.
During work, coal is introduced into in coal bunker 9, then pass through to enter coal supply auger 1 into coal bunker 9, entering coal bunker 9 makes coal stable can enter coal supply auger 1, prevent coal supply auger 1 from dallying, the coal entered in coal supply auger 1 is sent to coal exit 8 and enters in boiler, when motor 2 drives coal supply auger 1 to rotate, photoelectric counter 6 have recorded the number of times that optoelectronic induction baffle plate 5 rotates under motor 2 drives, and motor 2 drives number of revolutions to be also the number of times that coal supply auger 1 rotates.The number of times that known coal supply auger 1 rotates, rotate the quantity of adding coal to boiler each time to conjunction coal supply auger 1, namely the quantity of coal supply can be calculated, can count coal supply quantity accurately, certain interval is had between optoelectronic induction baffle plate 5 and photoelectric counter 6, the two can be adjacent but do not contact, and do not rub mutually, and not easy to wear.
As in Fig. 2, preferably, coal supply auger 1 is located on framework, and coal supply auger 1 coal-feeding end 7 is lower than coal exit 8.Utilize the gap between the deadweight minimizing coal cinder of coal and coal cinder, improve the accuracy of metering.
