specific Embodiment 1

[0024] refer to Figure 1 to Figure 3 As shown, the cylinder wall heating device 4 includes an air collection box 41, an air induction device 42, a heating pipe 43, an air outlet pipe 44 and an external heat source. The air collection box 41 is arranged at the tail end of the drum body 1 to collect the For the exhausted flue gas, the air induction device 43 communicates with the gas collecting box 41 to introduce the high-temperature flue gas in the gas collecting box into the heating pipe 43, and the heating pipe 43 is attached to the wall of the drum body 1 to support the drum body 1. The wall is heated, the air outlet pipe 44 communicates with the heating pipe 43 and the gas collecting box 41 to form a circulating air path, and the external heat source provides high-temperature air into the heating pipe.

specific Embodiment 2

[0027] refer to Figure 4 , Figure 5 As shown, the cylinder wall heating device includes a gas collecting box 41a, a heating burner 42a and a heating pipe 43a, and the gas collecting box 41a is arranged at the tail end of the drum body 1 to collect the smoke discharged from the drum body 1 and the heating pipe 42a, The heating burner 42a provides high-temperature flue gas into the heating pipe 43a, and the heating pipe 43a is attached to the wall of the drum body 1 to heat the wall of the drum body 1, and the flue gas in the heating pipe 43a is discharged through the gas collecting box 41a.

[0028] When the above-mentioned asphalt regeneration drum is working, the recycled asphalt material enters the drum body 1 from the feed port at the front end of the drum body 1, and the recycled asphalt moves to the tail end of the drum body 1 with the rotation of the drum body 1, and at the same time, the drying material burner 3 pairs of regeneration The asphalt material is dried and...

specific Embodiment 3

[0030] refer to Figure 6 As shown, the drum body 1 includes an inner drum 11 and an outer drum 12, a heating channel 13 is formed between the inner drum 11 and the outer drum 12, and the drum wall heating device is connected to the heating channel 12 and heats it, and the drum wall heating device 4 It is heat conduction oil heating device, hot air heating device, burner heating device, electric heating device or other heating methods.

[0031] When the asphalt regeneration drum mentioned above is working, the recycled asphalt material enters the inner drum, and when the drum body 1 rotates, the inner drum 11 rotates relative to the outer drum 12, and the drum wall heating device 4 heats the drum wall of the inner drum 11 to asphalt through the heating channel. The temperature at which the raw material melts into a liquid makes the recycled material bonded on the inner wall of the cylinder have considerable fluidity.

Abstract

The invention relates to the technical field of stirring equipment, and especially relates to an asphalt regeneration roller and a method for preventing materials from being stuck on the roller internal wall. The asphalt regeneration roller comprise a roller body, a roller driving device, and a baking material combustor; the roller driving device is connected to the roller body to drive the roller body to rotate; and the baking material combustor is connected to the front end of the roller body and is used to heat the regenerated asphalt in the roller body. The asphalt regeneration roller also comprises a roller wall heating device, and the roller wall heating device is connected to the roller body and is capable of heating the wall of the roller body to a temperature at which the asphalt in the roller body can be converted into a fluid. In the conventional method, the materials stuck on the wall are removed by blades; while in the provided asphalt regeneration roller, a roller wall heating device is used to heat the inner wall of a dry roller so as to convert the stuck asphalt into fluid, thus the roller inner wall material sticking problem can be radically solved; the cleaning efficiency is high, the stable operation of the roller body can be guaranteed, and thus the production and maintenance costs are reduced.

Description

technical field [0001] The invention relates to the technical field of mixing equipment, in particular to an asphalt recycling drum and a solution to the sticky material on the inner wall of the asphalt recycling drum. Background technique [0002] Asphalt concrete regeneration equipment is the old asphalt mixture planed from the invalid asphalt pavement by using regeneration technology. Raw materials are evenly mixed to produce high-quality asphalt concrete. Since the old asphalt mixture will release a large amount of smoke when the temperature reaches above 130°C, the drying degree inside the existing asphalt recycling drum is usually below 130°C, and the heated old asphalt material is sticky and easy to stick to the drum On the inner wall and blades, it is necessary to manually clean regularly, otherwise it will affect the continuity of production, reduce production efficiency and mixing quality. [0003] In order to solve the above problems, if the applicant in this ca...
