Description
Technical field
The present invention relates to a kind of materia metering methods, especially suitable for asphalt mixing plant.
Background technology
Asphalt mixing plant is the source equipment for building high-grade highway, as asphalt mixing plant is given birth to
The development of manufacturing technology and the requirement of high-grade highway are produced, it is higher and higher to the quality requirement of mixture.Asphalt
Grading accuracy relation is to the total quality of bituminous highway construction, and without accurate grading as premise, the quality of finished product material is with regard to nothing
Method ensures.Therefore, the accuracy of mixture gradation how is improved, is increasingly paid attention to by each manufacturer.
Different match ratios, different to the control point of grading of aggregates, the sieve specification of demand is also just different, therefore each is matched
Composition and division in a proportion always has a kind of material to play a crucial role the finished product material quality produced according to the match ratio, which is known as the pass of match ratio
Key material is known as crucial sieve by the sieve of critical component.The proportioning accuracy of critical component and the ratio essence in match ratio
Degree is the key factor for influencing finished product material quality.
Present manufacturer of mixing station generally uses cumulative measurement mode in batches in aggregate batching, each material
Batching mode is identical, there is no guarantee that the technique and system of critical component proportional precision in match ratio.
Invention content
For the existing Weighing system and batching mode of asphalt mixing plant, the present invention provides a kind of based on key
The aggregate measuring method of sieve can greatly improve proportional precision of the critical component in grading, improve the accuracy of grading, carry
The quality of high finished product material.
The design scheme of the present invention is as follows：
A kind of aggregate secondary measurement method based on crucial sieve, characterized in that include the following steps：
Step 1：Determine key sieve and critical component：
Critical component mark when confirming that critical component or retrieval establish match ratio according to match ratio, confirms the match ratio
In critical component；
Step 2：Calculate the pre-weighing value of critical component：
The weighing desired value that each material is calculated according to match ratio and single-deck material weight of material, according to the weighing of critical component
Desired 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 a certain fixed value of proportioning gravimetric value；
Step 3：Mark is interrupted in automatic gauge dispensing, the weighing for establishing critical component：
Dispensing is carried out respectively according to the dispensing of setting sequence, dispensing algorithm and each material weighing desired value, each material meter
After the completion of amount, its practical variable is recorded, critical component carries out dispensing by its pre-weighing value, and dispensing reaches the pre- title of critical component
When magnitude, dispensing interruption is carried out, interrupts the weighing interruption mark for establishing critical component when critical component metering, and record crucial object
The primary practical weighing value of material；
Step 4：The second weighing value of critical component calculates and dispensing：
According to the practical weighing value of unclassified stores, the primary reality of when critical component is coordinated to claim magnitude calculation critical component
Second weighing value, and mark is interrupted according to the metering method of metering system setting and the weighing of dispensing algorithm and critical component, it presses
The secondary measurement of critical component, dispensing are carried out according to the second weighing value of the critical component of calculating, each material is practical when metering claims
When magnitude error occurs with its desired value, the secondary measurement method of critical component can keep ratio of the critical component in match ratio
Example precision, meets proportion requirement of the critical component in match ratio.
In step 2, weighing desired value × setting pre-weighing ratio-key of pre-weighing value=critical component of critical component
The suspension amount of material.
In step 3 and 4, dispensing algorithm is that each material metering uses practical suspension amount when upper disc gage amount as this
The suspension amount of material metering, when the suspension amount calculating of each material subtracts closing material bin door with the practical weighing value of this kind of material
Suspension amount of this kind of material shutdown gravimetric value as this material metering, since Dose times interval is shorter twice, material storage
The Vibration Condition variation of level of filler material, equipment barometric information, bituminous mixing plant in storage is little, therefore this measures each object
Material suspension amount measured that the material suspended amount is almost the same with last time, this material metering is estimated using the practical suspension amount of a upper disk
When suspension amount can improve the measuring accuracy of material.
The advantage of the invention is that：
The present invention provides a kind of aggregate secondary measurement method based on crucial sieve, improves matching for critical component in match ratio
Material and proportional precision ensure the grading precision of critical component, critical component grading are made to meet design requirement to the greatest extent, improve
The quality and quality of finished product material.Metering system can be automatically performed calculating and metering in entire metering process；It can also basis
Live practical condition carries out manual intervention at any time.The pitch of the aggregate secondary measurement system based on crucial sieve of configuration is mixed
Solidifying soil stirring equipment is capable of providing the finished product material for meeting grading requirement, improves the quality of finished product material, builds highway to raising
Quality and service life reduce the generation of pavement disease.
