AI Technical Summary
Traditional asphalt recycling drums suffer from problems such as large heat loss, slow heating rate, and severe material sticking during the heating process, which affect production efficiency and product quality.
The design combines a scraping component and an air blowing component. The scraping component uses its own gravity to scrape off easily scraped material, while the difficult-to-scrape material is loosened and removed from the wall by compressed air ejected from the compressed gas nozzle. Combined with the inclined roller design and burner heating, effective cleaning is achieved.
It effectively cleans the material stuck inside the drum, reduces material waste, ensures the inside of the drum is clean, and maintains normal working efficiency.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of asphalt recycling technology, specifically to an asphalt recycling roller that avoids material sticking. Background Technology
[0002] Asphalt recycling involves sieving, heating, storing, and metering old asphalt mixtures removed from failed asphalt pavements, then adding them to the mixers of various asphalt mixing plants in different proportions. The mixtures are then uniformly mixed with the virgin material in the mixers to produce high-quality asphalt concrete.
[0003] In the asphalt recycling process, the asphalt recycling drum is one of the key pieces of equipment, responsible for heating the recycled wet material to a suitable temperature to remove moisture and other volatile substances. However, traditional asphalt recycling drums suffer from problems such as large heat loss, slow heating rate, and severe material sticking during the heating process, which affect production efficiency and product quality. Utility Model Content
[0004] The purpose of this invention is to overcome at least one of the defects of the prior art and provide an asphalt recycling roller that avoids material sticking.
[0005] The objective of this utility model can be achieved through the following technical solutions:
[0006] A bitumen recycling roller that avoids sticking includes:
[0007] frame;
[0008] The rollers mounted on the frame have a discharge port at one end and a feed port at the other end, with a screening section on the roller wall near the discharge port.
[0009] The scraping assembly includes a mounting arm disposed within the screening section and a plurality of scraper plates spaced apart on the mounting arm;
[0010] The air blowing assembly includes a compressed gas pipe disposed within the screening section and compressed gas nozzles spaced apart on the compressed gas pipe.
[0011] Furthermore, a chain is provided between the scraper and the mounting arm, through which the scraper is suspended on the mounting arm.
[0012] Furthermore, the number of compressed gas nozzles is the same as the number of scraper blades.
[0013] Furthermore, the outlet of the compressed gas nozzle is directly opposite the scraper plate.
[0014] Furthermore, the screening section is provided with a plurality of screening holes at intervals along its circumference.
[0015] Furthermore, a hopper is provided at the lower end of the screening section.
[0016] Furthermore, the asphalt recycling drum also includes a burner, which is disposed at one end of the drum and communicates with the interior of the drum.
[0017] Furthermore, the asphalt recycling drum also includes a drive device to rotate the drum.
[0018] Furthermore, the compressed gas nozzle is equipped with a fixed throttling orifice and a gas supply valve.
[0019] Furthermore, the roller is inclined and rotatably mounted on the frame, with its inlet higher than its outlet.
[0020] Compared with the prior art, this utility model provides an asphalt recycling drum that avoids material sticking. The asphalt recycling drum uses a scraping component to scrape off easily scraped sticky material inside the drum wall by its own gravity, and loosens the sticky material that is difficult to scrape off. Then, compressed air sprayed through the compressed gas nozzle removes the sticky material from the wall surface. This can effectively clean the recycled material sticky material inside the drum, reduce raw material waste, ensure the cleanliness of the inside of the drum, and maintain normal working efficiency.
