Description
Technical field
The present invention relates to a kind of materia metering method, it is particularly well-suited to asphalt mixing plant.
Background technology
Asphalt mixing plant is the source equipment building high-grade highway, with asphalt mixing plant life
Produce the development of manufacturing technology and the requirement of high-grade highway, the prescription more and more higher to compound.Asphalt
Level joins the total quality that accuracy relation is built to bituminous highway, does not have accurate level to join as premise, the quality of finished product material is just no
Method ensures.Therefore, how to improve the accuracy of mixture gradation, increasingly paid attention to by each manufacturer.
Different match ratios, different to the control point of grading of aggregates, the screen cloth specification of demand is also just different, therefore every kind of joins
Composition and division in a proportion always has a kind of material to play a crucial role to according to the finished product material quality that this match ratio produces, and this material is referred to as the pass of match ratio
Key material, is referred to as crucial screen cloth by the screen cloth of critical component.The proportioning accuracy of critical component and the essence of the ratio in match ratio
Degree is the key factor of impact finished product material quality.
Present manufacturer of mixing station is general in aggregate batching to adopt cumulative measurement mode in batches, each material
Batching mode is identical, there is no guarantee that the critical component technique of proportional precision and system in match ratio.
Content of the invention
Existing Weighing system for asphalt mixing plant and batching mode, the present invention provides one kind based on key
The aggregate measuring method of screen cloth, can greatly improve proportional precision in level is joined for the critical component, improve the accuracy that level is joined, carry
The quality of high finished product material.
The design of the present invention is as follows:
A kind of aggregate secondary measurement method based on crucial screen cloth, is characterized in that, comprise the following steps:
Step 1: the crucial screen cloth of determination and critical component:
Critical component is confirmed according to match ratio or retrieves the critical component mark set up during match ratio, confirm in this match ratio
Critical component；
Step 2: the pre-weighing value of calculating critical component:
Calculate the weighing desired value of each material according to match ratio and single-deck material weight of material, according to the weighing target of critical component
Value and suspension amount calculate the pre-weighing value of critical component or are directed to a certain match ratio, set the pre-weighing value of critical component as less than
The a certain fixed value of proportioning gravimetric value；
Step 3: automatic gauge dispensing, the weighing setting up critical component is interrupted identifying:
Dispensing order, dispensing algorithm and each material weighing desired value according to setting carry out dispensing respectively, and every kind of material metering is complete
Cheng Hou, records its actual variable, and critical component carries out dispensing by its pre-weighing value, and dispensing reaches the pre-weighing value of critical component
When, carry out dispensing interruption, mark is interrupted in the weighing interrupting setting up critical component during critical component metering, and records critical component
Once actual weighing value；
Step 4: the second weighing value of critical component calculates and dispensing:
According to unclassified stores actual weighing value, cooperation, when the once actual of critical component claims the secondary of magnitude calculation critical component
Weighing value, and mark is interrupted in the weighing of the metering method according to metering system setting and dispensing algorithm and critical component, according to meter
The second weighing value of critical component calculated carries out the secondary measurement of critical component, dispensing, the actual weighing value of each material when metering
When error with its desired value, the secondary measurement method of critical component can keep ratio essence in match ratio for the critical component
Degree, meets proportion requirement in match ratio for the critical component.
In step 2, the weighing desired value × setting pre-weighing ratio-key of the pre-weighing value=critical component of critical component
The suspension amount of material.
In step 3 and 4, dispensing algorithm is that every kind of material metering adopts actual suspension amount during a upper disc gage amount as this
The suspension amount of material metering, the suspension amount of every kind of material calculates when deducting closing material bin door with the actual weighing value of this kind of material
This kind of material close the door gravimetric value as the suspension amount of this material metering, because Dose times are spaced shorter, material storage twice
Level of filler material in storage, equipment barometric information, the Vibration Condition of bituminous mixing plant change less, and therefore this measures every kind of thing
Material suspension amount measured with last time that this material suspended amount is basically identical, and the actual suspension amount using a upper disk estimates this material metering
When suspension amount can improve the measuring accuracy of material.
It is an advantage of the current invention that:
The present invention provide a kind of aggregate secondary measurement method based on crucial screen cloth, improve match ratio in critical component dispensing and
Proportional precision, farthest ensures that the level of critical component joins precision, makes critical component level join and meets design requirement, improves finished product
The quality of material and quality.Metering system can be automatically performed calculating and metering in whole metering process；Can also be according to scene
Practical condition, carries out manual intervention at any time.The bituminous concrete of the aggregate secondary measurement system based on crucial screen cloth for the configuration
Mixing plant can provide and meet the finished product material that level joins requirement, improve the quality of finished product material, thus improving the quality built highway
And service life, reduce the generation of pavement disease.
Brief description
