The specific embodiment

Be as shown in Figure 1 the utility model provide a kind of simple in structure, the metering device that is used for the filter throughput of filtration that the mineral after can filtering filter accurately measure.The micro computer that described metering device comprises cylinder 1 and supports the installation shaft 2 of described cylinder 1, laser detector 3 and transmission device thereof, guide rail 4, speed probe 5, drive unit 6 and dispose signal acquisition process module 8, described guide rail 4 are disposed axially in the outside of described cylinder 1 along described cylinder 1; Described laser detector 3 is installed on the described guide rail 4 by transmission device; Described transmission device is connected with the output shaft of described drive unit 6; Described speed probe 5 is arranged on the described installation shaft 2; The output of described laser detector 3 and described speed probe 5 all is connected with the input of described micro computer.After adopting the filter output metering device of described structure, import the signal acquisition process module 8 of micro computer simultaneously by the tach signal of the thickness signal of the mineral of absorption on the cylinder 1 that laser detector 3 is recorded and the cylinder 1 that speed probe 5 records, through the processing of described signal acquisition process module 8 and by the output that just can on the display of micro computer, directly demonstrate the mineral that described filter filters behind the following integrating formula integrating, thereby realize filter is filtered the accurate metering of mineral output.Described integrating formula is:

$W=\mathrm{\&rho;}\underset{t_1}{\overset{{\mathrm{<figure-callout\; id="2"\; label="t"\; filenames="HDA0000023838720000011.png"\; state="\{\{state\}\}">t</figure-callout>}}_2}{\mathrm{\&Sigma;}}}\mathrm{\&Delta;W}$

$\mathrm{\&Delta;W}=\underset{1}{\overset{n}{\mathrm{\&Sigma;}}}\mathrm{\&Delta;S}=\underset{1}{\overset{n}{\mathrm{\&Sigma;}}}a\&CenterDot;b_n\&CenterDot;C_n=a\&CenterDot;L\&CenterDot;\stackrel{\&OverBar;}{C}$

$a=2\mathrm{\&pi;\&omega;T}(r+\frac{1}{2}\stackrel{\&OverBar;}{C})$

$\stackrel{\&OverBar;}{C}=\frac{1}{n}\underset{1}{\overset{n}{\mathrm{\&Sigma;}}}{C}_n$

In the formula: ρ: the proportion of mineral

W:t1 is to the cumulative production of interior mineral of t2 period

Δ W: the instantaneous concentrate output in per scan period

A: the coating width in per scan period T is averaged the arc length at coating thickness center

T: scan period, the one way traveling time of laser detector between two limit switches

ω: filter rotating speed

R: filter radius roller

N: in per scan period, the sampling number of laser detector

Cn: the single coating thickness that laser detector detects

L: coating length is taken as filter filtering surface width

As shown in Figure 2, the integrating principle of above-mentioned integrating formula is that the mineral output W of filter can be obtained by several mine belt Δs W integrating; And Δ W can be obtained by n the little ore deposit Δ S of unit integrating, obtains the above-mentioned integrating formula of t1 to interior mineral output of t2 period thus.

Described drive unit 6 is used for driving laser detector 3 along cylinder 1 axially reciprocating, thereby realize the thickness that is adsorbed onto the mineral on the described cylinder 1 is measured, so if described drive unit 6 adopts engine device, then need when reverse in end that described laser detector 3 moves to cylinder 1, the artificial reverse operating that carries out, baroque reversing device must be set at the output of described engine, make the structure of whole metering device very complicated like this, cost is also very high, and is not easy to cooperate with micro computer.Drive unit 6 described in the utility model for this reason is a drive motors; Be provided with limit switch 7 at described guide rail 4 two ends, the output of described limit switch 7 is connected with the input of described micro computer, and the input of described drive motors is connected with the output of micro computer.So just, can make the structure of described metering device very simple, utilize cooperating of limit switch 1 and laser detector 3 and drive motors simultaneously, can realize very easily that driving laser detector 3 is along cylinder 1 axially reciprocating, and can cooperate with micro computer, the signal that makes laser detector 3 backs that limit switch 1 is sent passes to drive motors by computer, and simultaneously carry out accurate recording along the time of described cylinder 1 an axial one-stroke or a round trip by 8 pairs of laser detectors 3 of signal acquisition process module of micro computer, improve the precision of the above-mentioned formula integrating mineral thickness of utilization.

Described laser detector 3 can adopt laser thickness gauge, but operation principle according to described laser thickness gauge, when there is a large amount of gaps in testee inside, the accuracy rate of the thickness of the object that laser thickness gauge is measured is lower, can reduce the accuracy of metering so greatly, in order to improve the parasexuality of laser detector measurement data, laser detector 3 described in the utility model is a laser range finder.During use, described laser range finder is constantly measured laser emission point to the distance of having adsorbed cylinder 1 surface behind the mineral, just can calculate over time thickness through the processing of described signal acquisition process module 8 again, guarantee the accuracy of measuring attached to the mineral on cylinder 1 surface.
