Description
Technical field
The present invention relates to a kind of discontinuous charging type coal-burning boiler, relate in particular to a kind of with the reinforced coal bunker of the discontinuous charging type coal-burning boiler of function of weighing.
Background technology
Coal-burning boiler is widely used in industry-by-industry as a kind of steam commonly used and hot water generator.At present, most of coal-burning boilers are to add fire coal by coal bunker or travelling belt, and the reinforced coal-burning boiler of continous way often adds coal-fired by travelling belt, but not the reinforced coal-burning boiler of continous way normally adopts coal bunker interpolation coal burning way.Add coal-fired boiler at adopting traditional coal bunker mode, change existing coal bunker and need spend higher cost, and the coal bunker under changing can not effectively utilize again, also increase cost virtually, and just using the cheating of LOAD CELLS weighing when coal bunker does not put down fully when utilizing conventional device to avoid coal-fired weighing fully.Often need to carry out weighing by meausring apparatus earlier for using coal bunker to add weight coal-fired in the coal-burning boiler, add the coal-fired time having increased virtually, exist error and operational numerous and diverse operation when also existing after the coal-fired weighing simultaneously in meausring apparatus adds coal bunker to.
Therefore, pressing for provides a kind of dynamic weighing of coal-burning boiler coal bunker, can in the process of coal bunker interpolation fire coal, carry out weighing by the fire coal to its loading, and, can prevent effectively when coal bunker not exclusively puts down in the weighing process that the bottom LOAD CELLS can't accurately weigh the cheating of coal-fired weight by sensor being set at its crucial weight bearing area.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of dynamic weigher of coal-burning boiler, by the coal bunker on the existing coal-burning boiler is reequiped, make it have the function of weighing, can in the process of coal bunker interpolation fire coal, carry out weighing by the fire coal to its loading, and, can effectively prevent the cheating that coal bunker not exclusively puts down in the weighing process by sensor being set at its weight bearing area.
In order to solve the problems of the technologies described above, the object of the invention is to provide a kind of dynamic weigher of coal-burning boiler, comprise the coal bunker that is provided with rotatable rocking arm, be provided with the support of the rotary joint that matches with rocking arm; rocking arm connects the pressure sensor assembly of a top of the trellis by lifting rope; the support bar that described support is positioned under the coal bunker is provided with the bottom LOAD CELLS; the rotary joint place is provided with bearing; nested pivot pin sensor in the bearing; pivot pin sensor two ends are provided with fixed pulley equally; two rocking arm ends of coal bunker are provided with hinge arrangement; the fixed pulley at this hinge arrangement and pivot pin sensor two ends is nested, and the pressure sensor assembly that props up top of the trellis all is connected with weighing control system with the pivot pin sensor.
Adopt the technique effect that technique scheme reached to be: this coal bunker is lifted by the rocking arm support and the lifting rope of its cooperation, can be effectively to the motion channeling conduct and the location of coal bunker, the lifting rope that is provided with by the support upper end lifts coal bunker, thereby coal bunker rising under the effect of rocking arm, flip-flop movement are reached boiler is added coal-fired purpose.Owing to be provided with the pressure sensor assembly of a top of the trellis, the support bar that support is positioned under the coal bunker is provided with the bottom LOAD CELLS, the pivot pin sensor at rotary joint place, such setting makes coal bunker possess the function of weighing, can when adding fire coal, be that the fire coal that is loaded carries out weighing for boiler, the interpolation of fire coal and the operation of weighing are merged, effectively saved the time; Be provided with pressure sensor assembly at a top of the trellis place simultaneously; rotating shaft place of rocking arm and coal bunker is provided with the pivot pin sensor, this pressure transducer cooperates pivot pin sensor and bottom LOAD CELLS to detect can prevent that coal bunker bottom LOAD CELLS when not exclusively putting down from can not accurately weigh the cheating of weight coal-fired in the coal bunker;
Further, the quantity of described rocking arm is two, and is symmetricly set on the both sides of coal bunker.In the support symmetria bilateralis two rocking arms are set and make better location and guiding to the lifting upset of coal bunker, can overcome the dislocation of coal bunker horizontal direction effectively.
Further, be provided with the reinforcement that is connected and fixed between described two rocking arms.Reinforcement is set eliminates two relative motions between rocking arm, keep the stable of coal bunker, also the accurate measuring accuracy of pivot pin sensor.
Further, described pressure transducer is a S type pressure transducer.The pressure that S type pressure transducer can detect top of the trellis delicately changes, and not exclusively puts down the cheating that coal bunker is just done the bottom weighing in the weighing process by cooperating to detect effectively to place with bottom LOAD CELLS and pivot pin sensor.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments:
Fig. 1 is the main TV structure synoptic diagram of coal-burning boiler dynamic weighing coal bunker of the present invention;
Fig. 2 is the plan structure synoptic diagram of coal-burning boiler dynamic weighing coal bunker of the present invention;
Embodiment
As Fig. 1, shown in Figure 2, the dynamic weighing coal bunker of a kind of coal-burning boiler of the present invention, comprise that xsect is trapezoidal coal bunker 1, riveted joint has rotating rocking arm 2 in the left and right sides of coal bunker 1; other end of rocking arm 2 links to each other with support 3; rocking arm 2 can rotate around the rotary joint 5 with support 3 junctions; an end of rocking arm 2 close coal bunkers 1 links to each other with wire sling 4; other end of wire sling 4 is walked around the pulley that the semi-girder at support 3 tops goes out; described rotary joint 5 places are provided with pulley, and the wheel shaft of rocking arm 2 and this pulley is fixedlyed connected, and the chute card of pulley is put in the spin slot on the support 3; S type sensor is set on the semi-girder, and S type sensor is connected with weighing control system.
The present invention realizes by following mode: the counterweight that will have standard weights is placed in the coal bunker 1, can pass through S type pressure transducer when lifting coal bunker 1, pivot pin sensor and bottom LOAD CELLS are read a gravimetric value, automatically calculate the weight ratio K of this gravimetric value and standard test weight by weighing control system, the penalty coefficient that this ratio K is weighed for this device, like this when weighing fire coal weight, by S type pressure transducer, the data that pivot pin sensor and bottom LOAD CELLS are read multiply by COEFFICIENT K and have just obtained coal-fired weight, the mode of weighing so both can guarantee weighing precision, the cheating when the simple coal bunker that occurs when relying on the bottom to weigh that can avoid again occurring in the process of weighing fire coal not exclusively falls.
Above-described only is preferred implementation of the present invention; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from basis of the present invention; can also make some distortion and improvement; for example can cancel pivot pin sensor or bottom LOAD CELLS; and utilize said apparatus in the switching process of coal bunker, to carry out dynamic weighing; under the situation of determining the K value; can satisfy the metering demand equally; these also should be considered as protection scope of the present invention, and these can not influence effect of the invention process and practical applicability.
