Description

Technical Field

[0001] The utility model relates to the technical field of anti-rutting agent production, in particular to an anti-rutting agent production unit. Background Art

[0002] Anti-rutting agent is an asphalt modifier used to prevent rutting disease on asphalt pavement. It is mainly composed of a variety of polymers, which can significantly improve the anti-rutting ability of asphalt mixture, effectively improve the low-temperature crack resistance, reduce the fatigue damage of pavement caused by traffic load, improve the mechanical performance index of asphalt mixture, enhance the adhesion between asphalt and aggregate, reduce the occurrence of pavement spalling disease, and improve the anti-aging performance of asphalt.

[0003] For example, the Chinese utility model with publication number CN205216783U discloses an anti-rutting agent production unit, including: a mixing system, whose inlet is connected to a raw material conveyor via a feeding pipe, for heating and mixing the input raw materials to obtain a melted liquid; a granulation system connected to the discharge pipe of the mixing system, for making the melted liquid output by the mixing system into liquid particles for output; a cooling and conveying system installed at the output end of the granulation system, for conveying the liquid particles output by the granulation system and cooling them into granular anti-rutting agents. The utility model is coherent and convenient to operate, has low labor intensity, and high production efficiency.

[0004] However, this solution has certain defects. For example, during the transmission process with the conveyor steel belt, the cooling of the back of the steel belt can only cool the part of the particles that are in contact with the steel belt, but the heat above the particles still exists and is conducted downward, so that the particles cannot be completely cooled in a short time and thus separated from the steel belt. The high-temperature liquid particles have great viscosity and are easily adhered to the surface of the steel belt, which is not conducive to collection. In addition, some debris will stick to the surface of the steel belt due to its small size. If it is not cleaned up in time, it will also affect subsequent production. Utility Model Content

An air delivery pipe 8 is inserted into the cooling pillar 5 on one side of the conveyor steel belt 4, and the air delivery pipe 8 is connected to the plurality of air jet pipes 9. A small blower 6 is arranged on one side of the support frame 3, and the exhaust port of the small blower 6 is connected to the air delivery pipe 8 through an air inlet pipe 7.

[0024] The air jet pipe 9 and the air jet head 10 are arranged to be inclined, and the inclination direction is toward the side away from the rotary granulator 2 .

[0025] As an optimization scheme of the utility model, a small blower 6 is provided to output gas, which is sent into the jet pipe 9 through the air inlet pipe 7 and the air delivery pipe 8, and then ejected from the jet head 10, so that the heat in the particles on the conveyor steel belt 4 is taken away by the airflow, and the airflow is blown to one side, that is, the airflow is unidirectional, the high-temperature gas can quickly move away from the unit, and the low-temperature air on the other side can quickly reduce the temperature near the unit, so that the particles can be continuously cooled.

[0026] See also Figure 1-Figure 3 As shown, the water mist cooling structure includes a water tank 11 and a water pump 12 arranged on one side of the support frame 3. The water suction port of the water pump 12 is connected to the water tank 11 through a pipeline. A water spray pipe 15 is arranged between the cooling pillars 5 directly below the jet pipe 9. The water spray pipe 15 is located below the conveyor steel belt 4. A plurality of atomizing nozzles 16 are evenly arranged on the water spray pipe 15. The atomizing nozzles 16 are arranged facing directly upward. A water pipe 14 is inserted into the cooling pillar 5 directly below the air pipe 8. The water pipe 14 is connected to multiple water spray pipes 15. The water outlet of the water pump 12 is connected to the water pipe 14 through a water inlet pipe 13.

[0027] As an optimization scheme of the utility model, a water pump 12 is used to pump water from the water tank 11, and the water is sent into the water spray pipe 15 through the water inlet pipe 13 and the water delivery pipe 14, and then sprayed onto the conveyor steel belt 4 from the atomizing nozzle 16. The evaporation of the water mist quickly absorbs heat, and the temperature of the conveyor steel belt 4 is quickly reduced, thereby quickly cooling the part where the particles contact the conveyor steel belt 4.

[0028] See also Figure 1-Figure 4 As shown, the scraping structure includes a fixed plate 19 fixed on the support frame 3 below the conveyor steel belt 4, a scraper 18 is rotatably installed in the support frame 3 above the fixed plate 19 through a rotating shaft 17, and a number of springs 20 are provided below the scraper 18 and between the fixed plate 19, the front end of the scraper 18 is in contact with the conveyor steel belt 4, and a slag discharge plate 21 is obliquely provided at the front end of the fixed plate 19; baffles 22 are provided at both ends of the slag discharge plate 21.

[0029] As an optimization solution of the utility model, the spring 20 is used to push the scraper 18 upward, so that the scraper 18 can be used to scrape off the material adhering to the conveyor steel belt 4. When the conveyor steel belt 4 shakes or the thickness changes, the spring 20 can automatically push the scraper 18 to fit the conveyor steel belt 4, so as to maintain the scraping effect, and the scraped material can fall along the slag discharge plate 21. At the same time, the baffle 22 can prevent the material from sliding out from both sides, making it convenient for the user to collect the material slag.

[0030] The use process of this utility model:

[0031] First, start the equipment. When the anti-rutting agent particles fall onto the conveyor steel belt 4, the airflow above will quickly cool the anti-rutting agent, and the conveyor steel belt 4 will absorb the heat of the particles. At the same time, the water mist sprayed by the atomizing nozzle 16 below will absorb the heat of the conveyor steel belt 4, so that the particles can be quickly cooled. Thermal expansion and contraction cause the particles to shrink inward, thereby separating from the conveyor steel belt 4 to prevent sticking. In some special cases, the sticky materials generated will be scraped off by the scraper 18 when passing through the scraper 18 and fall from the slag discharge plate 21.
