In the weighing device, the windproof pipe is additionally arranged on the outer part of the weighing rod, and the weighing block and the vibration absorber are additionally arranged below the analytical balance, therefore, the weighing rod is not influenced by air flow in the measuring unit to swing, and the self mass of the analytical balance is increased, so that the vibration is avoided, the normal operation of the measuring device is guaranteed, and the measuring accuracy is improved.
Description
Technical field
The utility model relates to a kind of weighing device based on flying dust carbon residue content measurement equipment in the heat power plant boiler ash discharge flue of weightless technology.
Background technology
Flying dust carbon residue content is the important indicator of reflection fuel-burning power plant coal-burning boiler burning efficiency in the heat power plant boiler flue, detects the flying dust remaining carbon in real time and will help instructing boiler operatiopn, correctly adjusts coal-air ratio, improves combustion control level; Rationally the index of control flying dust remaining carbon helps reducing cost of electricity-generating, improves the economy of unit operation.
The boiler flue flying dust remaining carbon pick-up unit that domestic power plant comes into operation at present all is to adopt Microwave Measurement Technique to measure remaining carbon in the flying dust basically, but Microwave Measurement Technique is subjected to influence that coal changes greatly to the measuring accuracy of flying dust remaining carbon, after in case the coal of boiler combustion changes, the measuring accuracy of remaining carbon just cannot be guaranteed, even the variation tendency of the measured value of remaining carbon and actual remaining carbon is all inconsistent.And the present situation of present domestic coal in power plant the variation of coal is bigger exactly.
Flying dust remaining carbon measuring equipment based on weightless technology has the advantage that measuring accuracy height, measuring accuracy are not subjected to the influence of coal variation.This device comprises the sampling unit of drawing ash sample, the measuring unit of measuring residual carbonaceous amount in the ash sample and the control module of measuring unit.Measuring unit comprises receives apparatus for ash, firing device, ash exhauster, turn device, jacking gear, weighing device and electric device, by electrical control, a series of repetitive cycling operations such as measuring unit is received ash, calcination, weighed, ash discharge and blowback are finished the surveying work to the flying dust residual carbon content.Weighing device is used for before the calcination of weighing ash sample and the weight after the calcination, to draw the residual carbonaceous amount in the ash sample.
In in-site measurement operating process in the past, the bar of weighing is rocked by the interior airflow influence generation of measuring unit easily, and the weight of analytical balance own is little, and the inner vibration that produces of measuring unit also can make the analytical balance generation vibrate, can influence the normal operation of pick-up unit like this, accuracy of detection reduces.
Summary of the invention
Goal of the invention: in order to solve the problems of the technologies described above, the utility model provides a kind of weighing device of flying dust remaining carbon measuring equipment, can prevent effectively that air-flow impacts weigh bar and analytical balance in the measuring unit.
Technical scheme: in order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:
A kind of weighing device of flying dust remaining carbon measuring equipment, comprise the bar of weighing, regulating sleeve, day flat frame and analytical balance, be provided with analytical balance in it flat frame, analytical balance is provided with regulating sleeve, regulating sleeve is provided with the bar of weighing, be with windproof pipe in the outside of the bar of weighing, and anti-airduct and weigh and leave the gap between the bar.
In the utility model, the upper end of described anti-airduct flushes with the bar of weighing, and the lower end of anti-airduct is fixed on the base plate of measuring unit.
In the utility model, the described balancing weight that below analytical balance, is provided with, the balancing weight below is provided with vibroshock.
Beneficial effect: the weighing device of flying dust remaining carbon measuring equipment of the present utility model is by adding anti-airduct in the bar outside of weighing, and below analytical balance, be equipped with balancing weight and vibroshock, can make the bar of weighing not produced by the interior airflow influence of measuring unit rocks, and the quality of analytical balance own is strengthened, reduced the measuring unit internal vibration to its influence, avoided the generation of resonance effect, guarantee the normal operation of measurement mechanism, improved measuring accuracy.
Description of drawings
Figure is a structural representation of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing the utility model is done further explanation.
As shown in the figure, the weighing device of flying dust remaining carbon measuring equipment of the present utility model comprises the bar 1 of weighing, regulating sleeve 3, day flat frame 4 and analytical balance 5.It flat frame 4 is fixed on the base plate of measuring unit, is provided with analytical balance 5 in sky flat frame 4 inside; Regulating sleeve 3 is set on analytical balance 5, and regulating sleeve 3 tops are provided with the bar 1 of weighing; At bar 1 outer cover of the weighing airduct 2 of setting up defences, anti-airduct 2 upper ends flush with the bar 1 of weighing, and the lower end of anti-airduct 2 is fixed on the base plate of measuring unit, prevent airduct 2 inwalls and weigh and leave certain interval between bar 1 outer wall; Be provided with balancing weight 7 below analytical balance 5, balancing weight 7 belows are provided with vibroshock 6, and the base plate of vibroshock 6 bottoms and measuring unit is fixed.
Because anti-airduct 2 is to be fixed on the base plate of measuring unit, rock so be difficult for producing when being subjected in the measuring unit airflow influence, stopped flowing of air-flow.When weighing, the anti-airduct 2 and the no any contact between the bar 1 of weighing, the stability of the bar 1 that guaranteed to weigh is provided with vibroshock 6 between analytical balance 5 and measuring unit base plate, avoid the measuring unit internal vibration that analytical balance 5 is impacted.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
