Abstract
The invention discloses a heating and mixing roller of a recycled asphalt aggregate. The heating and mixing roller comprises two aggregate baking rollers, wherein each aggregate baking roller comprises a barrel; a feeding end taper cylinder is arranged at the feeding end of the barrel; a feeding end labyrinth ring flange is arranged at the port of the feeding end taper cylinder; a feeding end labyrinth ring is arranged on the feeding end labyrinth ring flange; a discharge end taper cylinder is arranged at the discharge end of the barrel; a discharge end labyrinth ring flange is arranged at the port of the discharge end taper cylinder; a discharge end labyrinth ring is arranged on the discharge end labyrinth ring flange; two rolling rings and a gear are arranged at the side of the barrel; a blending straight plate, a blending sloping plate, a discharge sloping plate and a rotary plate are arranged at the lateral wall of an inner cavity of the barrel; a sleeve is arranged inside the inner cavity of the discharge end taper cylinder, and the two aggregate baking rollers are connected. The coking and deteriorating phenomena of the recycled aggregate caused by directly heating the recycled aggregate by an open fire are overcome, and aggregated rock can be fully and evenly mixed with asphalt.
Description
Technical field
The present invention relates to a kind of mixing plant of Recycled Asphalt Pavement, particularly a kind of heating mix cylinder of regeneration asphalt aggregate.
Background technology
At present, a lot of highways of China have entered the overhaul phase, the general bituminous pavement design life-span is 15 ~ 20 years, the whole nation flexible pavement overhauled in every year is nearly about 10%, approximately to have 3 ~ 50,000 li flexible pavement need in overhaul, the asphalt waste that annual milling is got off reaches millions of tons, these waste materials do not carry out regeneration, not only waste resource, and can take a large amount of land resources, environment is caused serious pollution.Therefore, the regeneration techniques of promotion and application waste material and equipment are the important measures of saving energy and reduce the cost, and can reduce to greatest extent the energy and raw-material consumption, reach the purpose of economy and resource environment " doulbe-sides' victory ".
Present domestic reworked material production, some producer utilizes naked light directly to heat to reworked material, causes reworked material that coking, denaturalization phenomenon are arranged, and has insufficient, the uniform defective of stirring.
Summary of the invention
In order to solve the problems of the technologies described above, the object of the invention is to provide a kind of heating mix cylinder of regeneration asphalt aggregate easy to maintenance, both can prevent regeneration aggregate coking, denaturalization phenomenon, again can with building stones and pitch fully, mix uniformly.
The technical solution used in the present invention is: comprise two aggregate drying rollers, described aggregate drying roller comprises cylindrical shell, the feed end of described cylindrical shell is provided with feed end cone cylinder, and the port of feed end cone cylinder is provided with feed end labyrinth ring flange, and feed end labyrinth ring flange is provided with the feed end labyrinth ring; The discharge end of cylindrical shell is provided with punishment in advance end cone cylinder, and the port of punishment in advance end cone cylinder is provided with punishment in advance end labyrinth ring flange, and punishment in advance end labyrinth ring flange is provided with punishment in advance end labyrinth ring; Be respectively equipped with a rolling ring on the side at cylindrical shell two ends, the side at cylindrical shell middle part is provided with a gear; The sidewall of described cylinder lumen is provided with and mixes and stirs straight plate, mixes and stirs swash plate and discharging swash plate, cylinder lumen and punishment in advance end cone tube inner chamber junction sidewall are provided with rotating plate, be provided with sleeve pipe in the punishment in advance end cone tube inner chamber, the punishment in advance end labyrinth ring of the first aggregate drying roller in two aggregate drying rollers and the feed end labyrinth ring of the second aggregate drying roller are connected.
The invention has the beneficial effects as follows: during work, new aggregate enters the first aggregate drying roller, and the feed hopper of regeneration aggregate in blending bin enters the second aggregate drying roller; Open burner, thermal-flame directly heats for new aggregate, high-temperature tail gas afterwards enters the second aggregate drying roller, utilizes high-temperature tail gas to carry out indirect heating to regeneration aggregate, has overcome naked light and has directly heated regeneration aggregate coking, the denaturalization phenomenon that causes to regeneration aggregate; The first aggregate drying roller, the second aggregate drying roller adopt material end labyrinth ring, feed end labyrinth ring to consist of dynamic seal (packing) and connect, have simple in structure, easy to maintenance, the advantage of good seal performance.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
The present invention is further illustrated below in conjunction with accompanying drawing.
As shown in Figure 1, the present invention includes two aggregate drying roller A, described aggregate drying roller A comprises cylindrical shell 6, and the feed end of cylindrical shell 6 is provided with feed end cone cylinder 3, the port of feed end cone cylinder 3 is provided with feed end labyrinth ring flange 2, and feed end labyrinth ring flange 2 is provided with feed end labyrinth ring 1; The discharge end of cylindrical shell 6 is provided with punishment in advance end cone cylinder 12, and the port of punishment in advance end cone cylinder 12 is provided with punishment in advance end labyrinth ring flange 13, and punishment in advance end labyrinth ring flange 13 is provided with punishment in advance end labyrinth ring 14; Be respectively equipped with a rolling ring 4 on the side at cylindrical shell 6 two ends, the side at cylindrical shell 6 middle parts is provided with a gear 5; The sidewall of described cylindrical shell 6 inner chambers is provided with and mixes and stirs swash plate 7, mixes and stirs straight plate 8 and discharging swash plate 9, cylindrical shell 6 inner chambers and punishment in advance end cone cylinder 12 inner chamber junction sidewalls are provided with rotating plate 10, be provided with the punishment in advance end labyrinth ring 14 of the first aggregate drying roller A1 among 11, two aggregate drying rollers of sleeve pipe A in punishment in advance end cone cylinder 12 inner chambers and the feed end labyrinth ring 1 of the second aggregate drying roller A2 is connected.
During work, new aggregate enters the first aggregate drying roller A1, and the feed hopper of regeneration aggregate in blending bin enters the second aggregate drying roller A2; Open burner, thermal-flame directly heats for new aggregate, high-temperature tail gas afterwards enters the second aggregate drying roller A2, utilize high-temperature tail gas to carry out indirect heating to the regeneration aggregate among the second aggregate drying roller A2, overcome naked light and directly heated regeneration aggregate coking, the denaturalization phenomenon that causes to regeneration aggregate; The first aggregate drying roller A1, the second aggregate drying roller A2 adopt material end labyrinth ring, feed end labyrinth ring to consist of dynamic seal (packing) and connect, have simple in structure, easy to maintenance, the advantage of good seal performance.
