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 control asphalt mixing plant mix material proportioning
Method.
Technical background
In existing highway making with, in bituminous mixture flow process, production mix proportion is usually by field experimentation room root
After going out according to target gradation design, pay compound mixing station operator and use.In the middle of refinery operation scheduling process, from
Seldom, screening result is difficult to represent each particle diameter actual ratio of high-volume cold burden, when cold burden level is joined hot aggregate bin quantity of sampling quantity comprehensively
When fluctuating larger, if adhering to the production mix proportion Instructing manufacture previously worked out using laboratory, control device dispensing, often lead
When causing mix station equipment to weigh dispensing feed bin occur flash, etc. material, extreme influence produced on-site efficiency, waste the energy and former material
Material.In addition, target（Cold burden）Mix-design is very authoritative, very strict, is that qualified unit is tested out, but it is not
Whole control device, at all cannot strict implement, in the middle of producing using management very arbitrarily, blindly；Production mix proportion finally controls
Weigh, but it is synthesized at the scene, is approximation, and have multiple proportionings, unauthoritative, adjust for experimenter
Change relatively more random, but do not allow asphalt mixing apparatus operator to have any variation.
When occur flash, etc. material, when equipment productivity is greatly reduced, mixing station operator be ensure speed of production, avoid
Delay pavement construction progress needs to take measures, common method is to link up with laboratory immediately, is adjusted out new by laboratory
Production mix proportion transfers to operator to be produced.But due to raw material often pole not specification, change of size is changeable, experiment
Room can not find in time as asphalt mixing plant operator and adjust proportioning.After operator employs laboratory adjustment
After proportioning toward contact can serious flash, etc. expect.Wasting surprising, yield reduction, linking up in difficult circumstances, operator typically can
Blindly remove to adjust production mix proportion under cold burden adjustment invalid situation, but this passive type changes the problem that match ratio is brought
Exactly solve the problems, such as the material such as flash, the level that but have lost compound is joined, reason is that operator cannot predict in advance and produces
The change of asphalt mixture gradation, that is, quality cannot be ensured.
Asphalt mixing plant production mix proportion is a dynamic adjustment management work, and the economic loss that existing method causes is non-
Chang great.
Content of the invention
The quality of production cannot be ensured, cause the contradictions such as economic loss for solving the above, the present invention proposes a kind of new
The proportioning curve controlling asphalt mixing plant mix material proportioning shows and input method, and alternatively referred to as " level joins bluetooth ", it is in behaviour
Work person, experimenter and equipment room play bridge, channeling.Proportioning curve show with input method can effectively solving hot and cold
Match ratio inequivalence, misfit the material problem such as flash of generation, improve mixing station production efficiency, ensure will not be because of change simultaneously
Match ratio and bring product quality problem, make product quality stable, be finally reached and reach optimization production procedure, improve and produce effect
Rate, reduces and links up cost, reduces resource consumption, the purpose of lifting economic benefit.
To achieve these goals, the present invention sets first with reference to curve, the i.e. upper limit, lower limit and target grading curve：
First determine mineral aggregate design grading limit and the size data of various asphalt, when the hot screen grade separation obtaining each feed bin
Afterwards, with Talbol's theory formula, the maximum density target level calculating every kind of building stones particle diameter joins percent of pass and bound；Institute
The percent of pass of two particle diameters that minimum grain size, maximum particle diameter and the user having the selected material type of taking-up in particle diameter percent of pass specifies
Value, is set up equation group according to laboratory formate gradation composition computing formula and carries out matching primitives, finally calculated using Gaussian elimination method
Optimum mix proportion solution under current screening data, is then recalculated with this solution again, draws upper and lower limit, target grading curve；
Target level is write music for a song line computation formula：
P ：Level joins percent of pass
PC ：The sieve classification of single feed bin joins percent of pass
When using s feed bin, then the level of m-th screen size is joined percent of pass value and is：
Secondly, read the original production mix proportion data of asphalt mixing plant control system by way of software embeds；
With the conversion formula of Target Mixture Ratio curve, match ratio data conversion is become current cooperation further according to production mix proportion
Compare grading curve；By drag current match ratio curve on vibration equipment sieve corresponding solve the problems, such as flash, etc. material same
When make the current match ratio grading curve after change between upper and lower limit grading curve, and close to target grading curve, formed
Optimum mix proportion curve；
Finally, force to allow system read new current match ratio data, formed by conversion formula optimum mix proportion curve
New data, changes, imports to the original operating system of asphalt mixing plant.
Production mix proportion and the conversion formula of Target Mixture Ratio curve：
R ：Hot material match ratio
P ：Level joins percent of pass
P

) / (1 - R
Colophonium
/ 100)
P n(n>1) = (R Breeze + ) / (1 - R Colophonium / 100).
The invention has the beneficial effects as follows can be joined to predict by the dragging change of curve shape according to the method operator
Composition and division in a proportion change after consequence, whether suitable whether the match ratio level after change is joined transfinites, change and have a much, or exceeded mesh
So, make operator both can solve in time flash, etc. material, it is to avoid the wasting of resources reduce equipment attrition, compound can be obviously improved again
The stability of product quality, is greatly improved asphalt highway construction quality.The present invention is alternatively referred to as " level joins bluetooth ", and it is behaviour
The bridge that work person, experimenter and equipment are linked up, can save communication cost, create considerable economic benefit to construction enterprises.
