Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of belted electronic balance, comprises front weighing scale frame 1, rear weighing scale frame 2, weighing instrument 7, speed pickup 8; Front weighing scale frame 1, rear weighing scale frame 2 are provided with LOAD CELLS 6, and front weighing scale frame 1, rear weighing scale frame 2 are arranged in the frame of band conveyor, and speed pickup 8 is connected by cable with weighing instrument 7; Described front weighing scale frame 1 is connected by cable with weighing instrument 7 respectively with the LOAD CELLS 6 of rear weighing scale frame 2.
Weighing carrier roller 3 quantity on front weighing scale frame 1, rear weighing scale frame 2 can be one or more groups; As shown in Figure 1, can be adjacent between front weighing scale frame 1 and rear weighing scale frame 2; As shown in Figure 2, conveying carrier roller 4 is separated with between front weighing scale frame 1 and rear weighing scale frame 2.
Weighing instrument 7 can be computing machine, also can be programmable controller.
Embodiment:
Front weighing scale frame 1 and rear weighing scale frame 2 respectively have two groups of LOAD CELLS 6,1 passage of the signal access weighing instrument 7 after the wiring parallel connection of two groups of LOAD CELLS 6 of front weighing scale frame 1,2 passages of the signal access weighing instrument 7 after the wiring parallel connection of two groups of LOAD CELLS 6 of rear weighing scale frame 2, the signal access weighing instrument 7 of speed pickup 8; The signal of front weighing scale frame 1 and rear weighing scale frame 2 respectively with the signal of speed pickup 8 by weighing instrument 7 computing, form two groups independently for the belted electronic balance 1 of monitoring and belted electronic balance 2, show instantaneous delivery and cumulative amount respectively; Meanwhile, the signal of front weighing scale frame 1, rear weighing scale frame 2, speed pickup 8 is together processed by weighing instrument 7 jointly, forms the normal belted electronic balance weighed, display instantaneous delivery and cumulative amount.
Test condition: belt width: 1000mm; Belt speed: 2.0m/s; Band conveyor maximum delivery mass flow: M=1000t/h.
The first step: when conveyor belt scale calibration, it is E that weighing instrument 7 records the belted electronic balance range calibration number after conveyor belt scale calibration;
Under empty belt situation, same test period:
Belted electronic balance 1: measured value 1.0t;
Belted electronic balance 2: measured value 1.3t;
Weight error=(1.3-1.0)/1.3=0.23;
Under band conveyor maximum delivery mass flow service condition, same test period:
Belted electronic balance 1: measured value 98t;
Belted electronic balance 2: measured value 100t;
Weight error: (100-98)/100=0.02.
Second step: belt conveyer scale normally run adjust zero point time, under empty belt situation:
Belted electronic balance 1: measured value 1.2t;
Belted electronic balance 2: measured value 1.6t;
Weight error: (1.6-1.2)/1.6=0.25.
3rd step: analyze
1) under the empty belt situation when conveyor belt scale calibration, weight error is 0.23, under the empty belt situation that belt conveyer scale normally runs when adjusting zero point, weight error is 0.25, under sky belt situation under situation equally, the two measured weight error is different, illustrate because belt soft durometer and environmental factor change cause metering to depart from calibration condition, utilize above-mentioned measured data, find out rule, belted electronic balance range calibration number E is compensated, restores situation during calibration, keep weighing precision to stablize.
2) when conveyor belt scale calibration and under band conveyor maximum delivery mass flow service condition, weight error is 0.02, under the empty belt situation that belt conveyer scale normally runs when adjusting zero point, weight error is 0.25, and the weight error measured by the two is different, there is linear error when maximum flow and minimum flow are described, utilize above-mentioned measured data, find out rule, the correspondence correction to belted electronic balance range calibration number E when carrying out different flow, keep weighing precision during fluctuations in discharge.
The utility model is that the weighing precision of belted electronic balance is stablized shape and provided basis for estimation and solution, and structure is simple, be easy to Project Realization.
