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 through coal bunker or travelling belt, and the reinforced coal-burning boiler of continous way often adds coal-fired through travelling belt, and coal-burning boiler normally adopts coal bunker to add coal burning way but not continous way is fed in raw material.Add coal-fired boiler to 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 through 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 through sensor being set at its crucial weight bearing area.
Summary of the invention
The technical matters that the present invention will solve provides a kind of dynamic weigher of coal-burning boiler; Through 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 through 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 that the coal bunker that is provided with rotatable rocking arm, the support that is provided with the rotary joint that matches with rocking arm, rocking arm are connected the pressure sensor assembly of a top of the trellis through lifting rope; Described support is positioned at support bar under the coal bunker and is provided with the bottom LOAD CELLS, and 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, and the fixed pulley at this hinge arrangement and pivot pin sensor two ends is nested, and the pressure sensor assembly of a 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 through 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 make coal bunker possess the function of weighing, and can when adding fire coal for boiler, be that the fire coal that is loaded carries out weighing; The interpolation of fire coal and the operation of weighing are merged, effectively practiced thrift 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 fixing reinforcement of connection 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 through cooperating to detect effectively to place with bottom LOAD CELLS and pivot pin sensor.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is done further detailed explanation:
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
Like Fig. 1, shown in Figure 2, the dynamic weighing coal bunker of a kind of coal-burning boiler of the present invention comprises that xsect is trapezoidal coal bunker 1; Riveted joint has rotating rocking arm 2 in the left and right sides of coal bunker 1, and the other end of rocking arm 2 links to each other with support 3, rocking arm 2 can around with rotary joint 5 rotations of support 3 junctions; rocking arm 2 links to each other with wire sling 4 near an end of coal bunker 1, and the other end of wire sling 4 is walked around the pulley that the semi-girder at support 3 tops goes out, and said rotary joint 5 places are provided with pulley; the wheel shaft of rocking arm 2 and this pulley is fixedly connected; the chute card of pulley is put in the spin slot on the support 3, and S type sensor is set on the semi-girder, and S type sensor is connected with weighing control system.
The present invention realizes through following mode: the counterweight that will have standard weights is placed in the coal bunker 1; Can read a gravimetric value through S type pressure transducer, pivot pin sensor and bottom LOAD CELLS when lifting coal bunker 1; 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; The data of reading through S type pressure transducer, pivot pin sensor and bottom LOAD CELLS multiply by COEFFICIENT K and have just obtained coal-fired weight, and such mode of weighing 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 in the coal-fired process of weighing, occurring not exclusively falls.
Above-described only is preferred implementation of the present invention, should be pointed out that for a person skilled in the art; Under the prerequisite that does not break away from the present invention basis; 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 confirming the K value; Can satisfy the metering demand equally, these also should be regarded as protection scope of the present invention, and these can not influence effect and practical applicability that the present invention implements.
