Abstract
The utility model provides a coal metering device, which comprises a coal conveying belt, a belt scale, a belt scale instrument, a monitoring control device, a signal box and a limit switch, wherein the belt scale is installed on a bracket of the coal conveying belt, the coal conveying belt is provided with a rotating sensor, the belt scale and the rotating sensor are connected with the belt instrument through signal lines, the belt instrument is connected with the monitoring control device through the Ethernet, the monitoring control device is connected with the limit switch through the signal box, and the limit switch is positioned on a baffle of a discharge device on a coal bunker. The utility model has such the beneficial effects that due to adoption of the above technical solution, instant coal feeding amount and accumulated coal feeding amount can be precisely metered, and accumulated metering of coal consumption of each boiler can also be realized; running conditions of the boiler are assessed through data analysis, thereby providing reference for economical running of the boilers.
Description
Technical field
The utility model relates to a kind of WT-MSR, especially relates to a kind of coal metering device.
Background technology
China accounts for 1/4th of coal in China total amount consumed in the coal consumption with coal-burned industrial boiler at present.And using Industrial Boiler to be mostly the old boiler that tenure of use is long; Problem is a lot; One of them problem is: the boiler operatiopn measuring instrument is incomplete, and last coal amount does not have weighing system accurately to measure, and the operations staff is difficult to operation conditions is made judgement adjustment at any time.
Summary of the invention
The purpose of the utility model provides a kind of simple in structure, safe and reliable coal metering device.
The technical scheme of the utility model is: a kind of coal metering device; Comprise coal conveyer belt, belt conveyer scale, belt conveyer scale instrument, monitor controller, signal box and limit switch; Said belt conveyer scale is installed on the support of coal conveyer belt; Said coal conveyer belt is provided with rotation sensor, and said belt conveyer scale is connected said belt conveyer scale instrument with rotation sensor through signal wire, and said belt conveyer scale instrument connects said monitor controller through Ethernet; Said monitor controller is connected with said limit switch through said signal box, and said limit switch is positioned at the baffle plate place of the discharger on the coal bunker.
Advantage and the good effect that the utlity model has are:
Owing to adopt technique scheme, can realize that the instantaneous coal amount that goes up goes up the accurate measurement of coal amount with accumulative total, and also can realize cumulative measurement that through data analysis, the ruuning situation of examination boiler is for the economical operation of boiler provides reference to every steam coal amount.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
As shown in Figure 1; The utility model comprises coal conveyer belt 1, belt conveyer scale 2, belt conveyer scale instrument 4, monitor controller 5, signal box 6 and limit switch; Said belt conveyer scale 2 is installed on the support of coal conveyer belt 1; Said coal conveyer belt 1 is provided with rotation sensor 3, and said belt conveyer scale 2 is connected said belt conveyer scale instrument 4 with rotation sensor 3 through signal wire, sends the weighing-up wave and the belt turn signal of belt conveyer scale 2 to belt conveyer scale instrument 4; Said belt conveyer scale instrument 4 is issued said monitor controller 5 through Ethernet with signal; Said monitor controller 5 is connected with said limit switch through said signal box 6, and said limit switch is positioned at the baffle plate place of the discharger 7 on the coal bunker 8, and boiler 9 is positioned at said coal bunker bottom.
The computing method of last coal amount are following:
At first confirm the installation site of belt conveyer scale 2, and then confirm the spacing Y of 8 in itself and each coal bunker.
Y ÷ v (belt speed)=t
T is the time delay of individual metering, and different coal bunkers 8 are provided with different t1, t2, t3
When coal is delivered to belt conveyer scale 2 places, when belt conveyer scale 2 is gone up the coal amount by non-zero instantaneous, begin metering.If this moment, the discharge plate of 1# coal bunker was closed, limit switch feedback shutdown signal, the last coal amount cummulative metering of beginning 1# coal bunker; When the discharge plate of 1# coal bunker is opened; Limit switch feedback opening signal; Finish the last coal amount cummulative metering of 1# coal bunker; Through sequential operation; Deduct coal amount on the accumulative total in t1 time delay, then this correction of coal amount
need add on the coal bunker semi-invariant of coal on next need on the accumulative total in this section period 1# storehouse.
Consider that the situation that two or more coal bunker discharge plates are closed simultaneously can appear in execute-in-place, the individual metering control setting position right of priority, serve as preferential promptly with coal conveyer belt 1 discharge plate limit switch signal foremost.
Above embodiment specifies the utility model, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
