Technical field
The present invention relates to the computational methods of belt conveyor conveying capacity.
Background technology
The conveying capacity of current belt conveyor is measured typically by the belt conveyer scale on belt to it.
Such as Fig. 1, belt conveyor 1 drags conveying articles by motor 15, and belted electronic balance includes weighing instrument, metering carrying roller
11st, tachogenerator 12, weighing bracket 13 and weighing sensor 14, wherein metering carrying roller 11, tachogenerator 12, weighing bracket
13 are installed in the frame of belt conveyor 1, and weighing sensor 14 is on weighing bracket 13, when material passes through, metering support
Roller 11 detects the material on belt conveyor 1, and weight of material, in weighing sensor 14, produces a direct ratio by leverage
In the voltage signal of belt load, this information of voltage is admitted to weighing instrument；Tachogenerator 12 is by belt conveyor simultaneously
Rate signal is also fed into weighing instrument, and weighing instrument is handled rate signal with weight signal, is drawn by integral operation
One instantaneous delivery value and accumulating weight value, and show respectively.
Because belt conveyer scale is limited by the limitation of mounting condition and use condition, it is necessary to often calibration.And the current generation limits
In prior art, to being weighed by the flow of belt conveyer scale, then anti-the calibration most direct mode of belt conveyer scale is exactly with weighbridge
Come over to calibrate belt conveyer scale, need to expend substantial amounts of human and material resources during calibration.Calibration process is frequently not belt simultaneously
The actual production process of conveyer, itself also easily produces larger error.

Power consumption Max；
Step 3：The power consumption E of belt conveyor contained goods in time T is obtained by calculating Max-Min；
Step 4：Measure the cumulative weight W of belt conveyor contained goods in time T；
Step 5：The goods weight value U that belt conveyor unit power consumption amount is conveyed is obtained by calculating W/E；
Step 6：After the normal operation of belt conveyor, the loading power consumption E (u) in measurement a period of time；
Step 7：Conveying capacity of the belt conveyor in this time is obtained by calculating UxE (u).
The unloaded power consumption Min, loading power consumption Max, loading power consumption E (u) measuring method are to pass through voltameter
Measurement.
The measuring method of the unloaded power consumption Min is that the method averaged by voltameter multiple repairing weld is measured.
The measuring method of the goods cumulative weight W is to be weighed by weighbridge.
The measuring method of the present invention is by monitoring belt conveyor power consumption, by calculating with regard to that can obtain its conveying capacity, this
The technical scheme of invention has advantages below：
1) measuring method is simple and easy to do, and measuring apparatus is simplified easy to maintain；
1) belt conveyer scale need not be installed, it is to avoid the transformation to belt conveyor structure；
2) after primary calibration, severe bad border operation need not be calibrated often；
3) accumulated running time is longer, and precision is higher, improves measurement accuracy.
Brief description of the drawings
Fig. 1 is the scheme of installation that belt conveyor uses conventional belt scale measuring method；
Fig. 2 is the flow chart of inventive belt conveyer measuring method.
Embodiment
The technique effect of the design of the present invention, concrete structure and generation is described further below with reference to accompanying drawing, with
It is fully understood from the purpose of the present invention, feature and effect.
The theoretical method for being used for the estimation of its conveying capacity by monitoring belt conveyor power consumption of the present invention proves part such as
Under：
1st, to belt conveyor motor：
The power at belt conveyor motor a certain moment
UtFor a certain moment electric moter voltage, ItFor a certain moment current of electric of motor,For motor power factor
Motor runs the electricity consumed within a period of time：
Motor voltage and power factor during normal use are almost unchanged, and above formula can be reduced to：
And electric current I during motor operationt=I1t+I2t；
I1tFor the no-load consumption electric current of a certain moment belt conveyor, I2tFor the loading institute of a certain moment belt conveyor
The electric current of consumption,
So：
Electricity of the belt conveyor actual consumption in conveying articles
2nd, to belt conveyer scale：
The instantaneous delivery F=kv of materialtRt
F is flow, unit：kg/s；K is weighing coefficient；vtFor belt speed, unit：m/s；RtFor weighing section load, list
Position：kg/m.
And Rt=R1t+R2t
R1tThe load caused for belt conveyer scale support and belt weight, R2tFor the load of present period
So：F=kvt(R1t+R2t)
The cumulative amount of belt conveyer scale is：
Due to belt conveyor, speed is varied less in the process of running, can be approximately considered vtIt is constant speed always, on
Formula can be reduced to：
Belt conveyer scale actual throughput after running skin is
Acting by the goods belt conveyor of M mass is：
Belt conveyor work is electricity of the electrical consumption on conveying articles
From above formulaWithIt is the proportional relation formula of a fixed coefficient, so, it is all to pass through belt
The quality and belt conveyor actual consumption of the goods of conveyer are a fixed coefficient proportionate relationships in the electricity of conveying articles.
Find the estimation that this coefficient i.e. available power table carries out conveying capacity instead of belt conveyer scale.
Therefore, as shown in Fig. 2 the technical scheme is that,
Step 1：Belt conveyor is allowed to dally and measure the unloaded power consumption Min of belt conveyor in setting time T；
Step 2：Allow belt conveyor to convey a certain amount of goods in setting time T and measure the loading of belt conveyor
Power consumption Max；
