Abstract
The invention relates to the field of road pavement control technology, and in particular relates to a method for controlling the ratio of mixture of asphalt mixing equipment. The method comprises the steps of drawing target proportioning grading, upper and lower limit production grading and current proportioning grading curves by reading original proportioning data, and adjusting the current proportioning grading curve to be close to a target grading curve to the great extent, so as to achieve the optimal production proportion. The method is convenient for operators to rapidly and reasonably adjust the formula through curve adjustment, so as to timely overcome the adverse effects such as overflowing, finally achieve the optimized production flow, improve the production efficiency, reduce the communication cost and improve the economic benefit.
Description
Technical field
The present invention relates to highway making control technology field, specifically a kind of method of controlling asphalt mixing plant mix material proportioning.
Background technology
At existing highway making with in bituminous mixture flow process, production mix proportion be generally by field experiment chamber, according to target gradation design, gone out after, pay the operating personnel of compound mixing station and use.In the middle of production mix proportion design process, from hot aggregate bin quantity of sampling quantity seldom, screening result is difficult to represent each particle diameter actual ratio of cold burden in enormous quantities comprehensively, when cold burden fluctuation of aggregate graduation is larger, if adhere to, use the production mix proportion that previously worked out in laboratory to instruct and produce, control appliance batching, feed bin generation flash while tending to cause mixing station equipment weigh batching, etc. material, greatly affect produced on-site efficiency, waste energy and raw material.In addition, target (cold burden) mix-design is very authoritative, very strict, is to have the unit of qualification to test out, but its final control appliance, at all cannot strict implement, in the middle of producing, use management very arbitrarily, blindly; Production mix proportion is finally controlled weighing, but it is synthesized at the scene, is approximation, and has a plurality of proportionings, unauthoritative, adjusts to change more arbitrarily concerning experimenter, does not but allow asphalt mixing apparatus operating personnel to have any change.
When occur flash, etc. material, when equipment productivity significantly reduces, the operator of mixing station for guaranteeing speed of production, avoid delaying pavement construction progress and need to take measures, common way is to link up with laboratory immediately, the production mix proportion being made new advances by laboratory adjustment transfers to operator to produce.But due to raw material utmost point specification not often, change of size is changeable, laboratory can not be as asphalt mixing plant operator timely discovery adjust proportioning.Operator used after the proportioning after laboratory is adjusted toward contact meeting serious flash, etc. material.In surprising, the yield reducation of waste, communication difficult circumstances, operator generally can adjust and under invalid situation, remove blindly to adjust production mix proportion at cold burden, but the problem that this passive type change match ratio is brought has solved the material problems such as flash exactly, but lost the grating of compound, reason is that operator cannot predict the variation of the asphalt mixture gradation of producing in advance, that is cannot ensure the quality of products.
Asphalt mixing plant production mix proportion is a dynamically adjustment management work, and the economic loss that existing method causes is very large.
Summary of the invention
For solving the above, cannot guarantee the quality of production, cause the contradictions such as economic loss, the proportioning curve that the present invention proposes a kind of new control asphalt mixing plant mix material proportioning shows and input method, also can be described as " grating bluetooth ", it plays bridge, channeling at operator, experimenter and equipment room.Proportioning curve shows and input method can effectively solve hot and cold match ratio inequivalence, misfit the material problems such as flash of generation, improve mixing station production efficiency, guarantee can not bring product quality problem because of changing match ratio simultaneously, make constant product quality, finally reach optimization production procedure, enhance productivity, reduce and link up cost, reduce resource consumption, promote the object of economic benefit.
To achieve these goals, first the present invention sets with reference to curve, be the upper limit, lower limit and target graduation curve: mineral aggregate design grading limit and the size data of first determining various bituminous mixture, after obtaining the hot screen grade separation of each feed bin, use Talbol's theory formula, calculate maximum density target grating percent of pass and the bound of every kind of building stones particle diameter; In all particle diameter percent of pass, take out the percent of pass value of two particle diameters of the minimum grain size, maximum particle diameter and the user's appointment that are selected material type, according to laboratory formate gradation composition design formulas, set up equation group and mate calculating, use Gaussian elimination method finally to calculate the optimum mix proportion solution under current screening data, and then recalculate with this solution, draw upper and lower limit, target graduation curve;
The target level line computation formula of writing music for a song:
P: grating percent of pass
PC: the screening grating percent of pass of single feed bin
When using s feed bin, the grating percent of pass value of m screen size is so:
Pm =
；
Secondly, the mode embedding by software reads the original production mix proportion data of asphalt mixing plant control system;
According to production mix proportion, with the conversion formula of Target Mixture Ratio curve, match ratio data transaction is become to current match ratio graduation curve again; By drag the sieve of vibration equipment on current match ratio curve corresponding solve flash, etc. make in the problem of material current match ratio graduation curve after change between upper and lower limit graduation curve, and close to target graduation curve, form optimum mix proportion curve;
Finally, force to allow system read new current match ratio data, by conversion formula optimum mix proportion curve, form new data, change, import to the original operating system of asphalt mixing plant.
The conversion formula of production mix proportion and Target Mixture Ratio curve:
R: heat material match ratio
P: grating percent of pass
p1=(R breeze+R1)/(1-R pitch/100)
pn (n>1)=(R breeze+ )/(1-R pitch/100).
The invention has the beneficial effects as follows according to the method operator and can change the consequence of predicting after match ratio is changed by dragging of curve shape, whether the match ratio grating after change transfinite, change have much, whether suitable or exceed standard very clear, make operator both can solve in time flash, etc. material, avoid the wasting of resources to reduce equipment attrition, can significantly promote the stability of compound product quality again, significantly improve asphalt highway construction quality.The present invention also can be described as " grating bluetooth ", and it is the bridge that operator, experimenter and equipment are linked up, and can save communication cost, to construction enterprises, creates considerable economic benefit.
