Description
Technical field
The utility model relates to a kind of modifying asphalt production unit, specifically, is a kind of hybrid modifying asphalt production unit, is used for the various modifying asphalts of continuous production, especially suitable for producing SBS modifying asphalt.
Background technology
Have with it in Modern Traffic medium pitch concrete road surface that driving is steady, comfortable, noise is low, maintenance is convenient, be easy to advantage such as reclaiming pitch and obtained application more and more widely in highway and the urban road at home and abroad.But, its work reliability and use range have been limited as the plain asphalt of one of its raw material because of himself cold short dropping down property of heat, particularly the big flow of Modern Traffic, heavy lift, at a high speed bituminous pavement is had higher requirement, as high-temperature stability, low-temperature cracking-resistance, anti-aging, antifatigue, antistripping ability, easily maintenance etc.In order to reach this requirement, must carry out modification to pitch, this has been made a large amount of research experiments both at home and abroad, from PE, EVA, PE+EVA, SBR, SBS etc., generally admit with SBS in face of a large amount of facts asphalt modification is had the good technical economic benefit.Because SBS (styrene-butadiene-styrene block copolymer) had not only had the elastic property of rubber but also have the thermoplastic properties of resin, thereby force of cohesion is big, toughness is high, in matrix pitch, be difficult to rely on they self the strength dispersion of height fast, therefore must the blended stock of matrix pitch and SBS be made multipass by shredder grinds, make SBS reach the micron order particle diameter, thereby SBS is evenly distributed in the matrix pitch.
According to the knowledge of the applicant, existing asphalt modification equipment has two kinds of structures.A kind of is circulating, milling apparatus is only established stirred pot of a grinding machine, its multipass only grinds and carries out between one jar of one mill, and the mixed slurry of SBS and matrix pitch flows out from the bottom of jar, and the top flows into, and the density of SBS is lower than pitch, even some SBS floats on bituminous top through stirring also, thereby be difficult to guarantee the grinding of all mixed slurries through identical pass, the particle diameter great disparity of SBS is bigger, this has not only influenced the performance of modified bitumen index, also wastes SBS.Another kind is a continous way streamline asphalt modification device, and its milling apparatus is one jar of one a plurality of series connection of barreling mill apparatus with said structure, uses grinding machine 3-7, stirred pot 2-6.Like this, though guaranteed SBS and of the grinding of matrix pitch blended stock by identical pass, but make the complex structure of milling apparatus, parts increase, and cost is very high, and energy consumption strengthens, it is big to take up room, when especially making wheeled apparatus, mounting or dismounting, transportation are all inconvenient, to user's overall economic efficiency is descended.
In addition, all the fail problems of inoculation of fine solution SBS of above-mentioned two kinds of structures, a large amount of theoretical investigation and engineering constructions facts have proved: 1, the blended stock of SBS and matrix pitch passes through 1-2 time grinding, and the index after 40-60 minute breed is better, SBS consumes lower, and power consumption is littler; 2, SBS breed more even more importantly than the swelling of SBS, it makes SBS form thinner, more uniform envelope reticulate chain structure to matrix pitch, and is mixed more even, more abundant with bituminous; 3, can not obtain in mechanical mill and need in conjunction with chemical modification under the situation of positive effect etc.Above-mentioned two kinds of structures, the finished product asphaltum of production is put in the storage tank, flows out while flow into, and is difficult to guarantee fully effectively to breed, thereby has caused performance of modified bitumen to reduce and the waste of SBS.
Above-mentioned two kinds of structures also have other shortcoming, as: the intermiscibility at matrix pitch and SBS is not under the good situation, lacks Aided Modification remedial measures and related device, is difficult to guarantee the up-to-standard rate of modifying asphalt; The auxiliary agent adding set is not set, under the situation that modifying asphalt need be deposited the long period, can't adds stablizer etc.
The utility model content
The purpose of this utility model is the shortcoming that overcomes existing asphalt modification equipment, provides a kind of simple and reasonable, satisfying under the identical technical requirements condition, can effectively reduce processing, the use cost of SBS consumption, energy expenditure and equipment; Can improve SBS crush efficiency, refinement granularity and dispersed homogeneous degree, have mechanically modifying and chemical modification, better adapt to the SBS modifying asphalt production unit of engineering construction needs.Realize that this purpose technical solution is:
A kind of hybrid modifying asphalt production unit, comprise the batch mixes device, milling apparatus, the inoculation device that link in regular turn, connect by pipeline between each device, pipeline is provided with valve, it is characterized in that: the shredder of described milling apparatus adopts special-purpose high speed shear homogenizing grinding machine, described inoculation device be provided with at least two parallel connections, isolate that one after the other is in that discharging is bred, bred in charging or the jar that breeds of discharging operating mode is bred, breeds, breeds in charging by valve.
Described milling apparatus is made of a shredder and a stirred pot series connection.
Described milling apparatus also can be by two shredders and a stirred pot, by grinding machine-stirred pot-grinding machine formation of connecting in proper order.
The outlet of described inoculation device is provided with the duct type shears.
Described inoculation device is provided with the auxiliary agent adding set, adds inlet with the auxiliary agent that respectively breeds jar respectively by pipeline and links.
Described batch mixes device comprises the mixing tank that the valve isolation alternately is in miscible, the miscible discharging operating mode of charging that passes through of asphalt delivery pump, the SBS electric screw transfer mechanism of being with measuring instrument and at least two parallel connections; The asphalt delivery pump links by pipeline and mixing tank, and pipeline is provided with under meter; The SBS electric screw transfer mechanism of band measuring instrument links with the SBS of mixing tank inlet respectively by pipeline.
The utility model has the advantages that:
1. the grinding effect owing to this high speed shear homogenizing grinding machine is equivalent to the effects that two to three series connection of normal mill are used, thereby can simplify the milling apparatus structure greatly, reduces grinding machine and stirred pot quantity, reduces installation cost and power consumption of the mill significantly.
2. because inoculation device is provided with the jar that breeds of at least two parallel connections, one after the other work can guarantee modifying asphalt is bred fully effectively stable performance; And can reduce the consumption of SBS, reduce the modifying asphalt cost.
3. be provided with the auxiliary agent adding set owing to breed jar, when modifying asphalt needs long period storage or performance less stable, can add auxiliary agent, make performance of modified bitumen more stable, the time lengthening is beneficial to construction, guarantees construction quality.
4. because the outlet of inoculation device is provided with the duct type shears, not under the good situation at the intermiscibility of matrix pitch and SBS, use the powerful shear agitation of shears, can improve the quality of modifying asphalt, stop substandard product.
