Description
Technical field
The present invention relates to asphalt mixing plant fields, and in particular to a kind of automatic blending method, one kind of bituminous mixing plant
The automatic batching system of bituminous mixing plant and a kind of bituminous mixing plant.
Background technique
Bituminous mixing plant is also referred to as asphalt concrete mixer, to produce bituminous concrete in batches.Existing asphalt mixing
Station owner will by cold burden system, drying system, hot material lifting system, shaker systems, hot aggregate bin system, metering stirring system, remove
The part such as dirt system, control system forms.Cold burden system connects drying system, and drying system connects hot material lifting system, hot material
Lifting system connects shaker systems, and shaker systems connect hot aggregate bin system, and hot aggregate bin system connection metering stirring system removes
Dirt system connects drying system, and control system is then used to control each system.
Include hot aggregate bin in hot aggregate bin system, the building stones for screening out to come from shaker systems are stored in hot aggregate bin (referred to as
Aggregate).Due to the difference of raw material, so the partial size and position in storehouse in each hot aggregate bin are different from, to vibrating screen if buying securities with all one's capital
System has damage, and hole capital after selling all securities will cause metering again and wait, and influences yield, so need to judge the material position in each feed bin, so as to
Ingredient is carried out to each feed bin.
However the bituminous mixing plant of existing structure is in process of production, because of cold burden feeding not in time or particles of aggregates mismatch
The problems such as, often there is hot aggregate bin and lack material and flash problem, waste client's energy, seriously affects equipment production production capacity.At this stage
The scarce material and flash for solving the problems, such as hot aggregate, rely primarily on manipulator's field experience, are deployed manually, to manipulator's technical ability etc.
Grade requires high, large labor intensity.
Therefore, to those skilled in the art, how to provide a kind of bituminous mixing plant automatic blending method and from
Dynamic feed proportioning system lacks material and flash time to reduce as far as possible, guarantees that equipment produces production capacity, becomes the skill of this field urgent need to resolve
Art problem.
Summary of the invention
In view of the deficiencies of the prior art, it is an object of that present invention to provide a kind of automatic blending method of bituminous mixing plant and certainly
Dynamic feed proportioning system lacks material and the appearance of flash problem so that hot aggregate bin is reduced or avoided, guarantees that equipment produces production capacity.
In order to solve the above technical problem, the present invention provides a kind of automatic blending method of bituminous mixing plant, the pitches
Mixing plant includes the N number of cold burden storehouse and N number of hot aggregate bin for storing different-grain diameter specification aggregate, and N is the integer more than or equal to 2,
The average grain diameter of aggregate stored by 1st cold burden storehouse, the 2nd cold burden storehouse ... n-th cold burden storehouse is sequentially increased, the 1st heat
The average grain diameter of aggregate stored by feed bin, the 2nd hot aggregate bin ... n-th hot aggregate bin is sequentially increased, and the 1st cold burden storehouse is corresponding
1st hot aggregate bin, corresponding 2nd hot aggregate bin ... the n-th cold burden storehouse in the 2nd cold burden storehouse corresponds to n-th hot aggregate bin, described automatic
Distribution includes the following steps:
Step 102: obtaining the storing amount of each hot aggregate bin；
Step 104: when the storing amount of i-th of hot aggregate bin is lower than the first preset value, raising the discharging speed in i-th of cold burden storehouse
Degree lowers the discharge rate in i-th of cold burden storehouse when the storing amount of i-th of hot aggregate bin is higher than the second preset value, wherein i is choosing
From the integer of 1-N, first preset value is less than second preset value.
The improvement of automatic blending method on the one hand as bituminous mixing plant of the present invention, the step 104 specifically:
