[0034] Referring to Figures 1 to 9 The present application provides a full-flexibility asphalt regeneration drying drum, which comprises a drum body 1, an internal support 2, a full-flexibility chain net 3, a material guiding blade 4, a front end support 5 and a rear end support 6. The drum body 1 is arranged obliquely, and the internal support 2 is fixedly arranged inside the drum body 1. The drum body 1 comprises a material guiding blade area 10 at the front end and a chain net material lifting area 11 at the rear end. The material guiding blade 4 is arranged in the material guiding blade area 10, and the full-flexibility chain net 3 is arranged in the chain net material lifting area 11. The front end support 5 is arranged at the front end of the drum body 1 to fix the front end of the internal support 2, and the rear end support 6 is arranged at the rear end of the drum body 1 to fix the rear end of the internal support 2.

[0035] The internal support 2 is composed of three support assemblies. The three support assemblies are connected by high-strength bolts. The first support assembly 20 comprises three support rings 23 arranged coaxially with the drum body 1, six crossbars 24 extending along the length direction of the drum body 1, and a plurality of support columns 25. The three support rings 23 are arranged at intervals along the length direction of the crossbar 1.

The two support rings are arranged at intervals along the length direction of the crossbar. The support columns 25 are arranged at intervals along the circumferential direction of the support ring 23 on the last support ring 23 at the last end of the second support assembly 21 and the third support assembly 22. One end of the support column 25 is connected to the support ring 23, and the other end is connected to the inner wall of the drum body 1 as the support of the internal support 2.

[0036] The full-flexibility chain net 3 comprises a plurality of vertical chains 30 and a plurality of horizontal chains 31, the full-flexibility chain net 3 is arranged between the support rings 23 and the drum body 1 and is arranged along the circumference and is spaced, the plurality of vertical chains are arranged along the extension direction of the drum, the opposite vertical chains 30 of the adjacent two support rings 23 are connected with a plurality of horizontal chains 31 arranged along the length direction of the vertical chain 30, the first end and the last end of the vertical chain 30 are welded with the inner wall of the drum body 1 at one end and are welded with the support ring 23 on the inner support 2 at the other end, and the vertical chain 30 is not fully tensioned when being welded, so that the vertical chain 30 of the full-flexibility chain net 3 has a certain swing space, and part of the vertical chain 30 is replaced by the support column 25 when being installed, the support column 25 can also fix the end of the horizontal chain 31, the support column 25 is arranged along the circumference of the support ring 23 and is spaced, and a group of support columns 25 are arranged every interval of the support ring 23 to replace the vertical chain.

[0037] The material guiding blade 4 is arranged obliquely on the inner wall of the drum body 1 and the end of the material guiding blade 4 extends into the front end of the chain net material lifting area 11, the end of the material guiding blade 4 is placed in the middle of the two full-flexibility chain nets 3, which is beneficial to the mixed material directly rushing into the full-flexibility chain net 3.

[0038] The end of the vertical chain 30 and the support column 25 connected with the inner wall of the drum body 1 is provided with a sliding ring 7, the sliding ring 7 can slide along the vertical chain 30 and the support column 25, which is helpful to remove the mixed material adhered to the vertical chain 30 or the support column 25.

[0039] The front end support 5 comprises a front end fixed ring 50 fixedly arranged at the front end of the drum body 1 and a plurality of circumferentially distributed support plates 51, one end of the support plate 51 is fixed on the front end fixed ring 50, and the other end extends into the drum body 1 and is connected with the support ring 23 of the inner support 2.

[0040] The rear end support 6 comprises a rear end fixed ring 60 fixedly arranged at the rear end of the drum body 1 and a plurality of circumferentially distributed connecting plates 61, one end of the connecting plate 61 is fixed on the rear end fixed ring 60, and the other end is connected with the inner wall of the drum body 1, and the rear end fixed ring 60 is detachably connected with the last support ring 23 of the third support assembly 22 through high-strength bolts.

[0041] Continuing to refer to Figures 1 to 9 When the present application is used, the asphalt regeneration mixture enters the drum body 1 from the feeding end, because the drum body 1 is arranged obliquely, the asphalt regeneration mixture has a certain speed to advance forward, and sequentially passes through the material guiding blade area 10 and the chain net material lifting area 11, and finally obtains the regeneration mixture with a certain temperature.

[0042] In the guide blade area 10, since the guide blade 4 and the inner wall of the drum body 1 are arranged at an angle, the axial speed of the asphalt mixture in the guide blade area 10 is relatively fast, and when entering the chain net lifting area 11, the mixture slows down at the junction of the two areas, and the mixture is easily accumulated at this place. Therefore, the end of the guide blade 4 is extended into the chain net lifting area 11 and placed between the two pieces of full-flexible chain net 3, which is beneficial to the mixture directly entering the full-flexible chain net 3 and avoiding the accumulation of the mixture caused by the collision of the mixture with the support column 25 or the vertical chain 30.

[0043] In order to better install the full-flexible chain net 3 and ensure a certain strength, an internal support 2 is arranged in the drum body 1, the internal support 2 is designed in a split type and divided into three support assemblies, the high-strength bolts are used to connect the assemblies, the front end support 5 is arranged at the front end of the drum body 1, and the end support 6 is arranged at the end of the drum body 1 to fix the internal support 2. The stability of the internal support 2 is enhanced by welding the part of the vertical chain 30 to the cylindrical support column 25 between the internal support 2 and the middle part of the drum body 1. Compared with the general drying drum, the number of rigid support columns 25 is greatly reduced, which helps to reduce the resistance of the mixture and the probability of the mixture adhering to the inner wall of the drum body.

[0044] The full-flexible chain net 3 is divided into horizontal chains 31 and vertical chains 30. Due to the connection of the vertical chains 30, the consistency of the movement of the full-flexible chain net 3 is greatly improved, and the gap between the horizontal chains 31 is controlled within a certain range. In this way, the full-flexible chain net 3 can effectively lift the coarse material with a diameter greater than D to a certain height and then drop it, which can form a curtain to enable the asphalt recycling mixture to more fully absorb the heat of the hot air passing through the drum body 1, thereby improving the heat energy utilization rate. When the full-flexible chain net 3 is used to lift the material, the fine material can leak into the drum bottom through the gap, so as not to absorb excessive heat and cause aging of the asphalt. Due to the properties of the asphalt mixture itself, after a certain period of production of the drying drum, a certain amount of recycled material will inevitably adhere to the inner wall of the drum body 1. The horizontal chains 31 of the full-flexible chain net 3 close to the drum body 1 will swing due to their own gravity, which can brush away part of the mixture adhering to the inner wall of the drum body 1. The two vertical chains 30 at the front end and the end of the full-flexible chain net 3 are welded to the inner wall of the drum body 1 at one end and to the support ring 23 at the other end. During welding, the vertical chain 30 does not need to be fully tensioned, which allows the vertical chain 30 to have a certain swing space and can self-clean the mixture adhering to the top of the chain during the operation of the drying drum.

[0045] The position where the support column 25 and the vertical chain 30 of the full-flexible chain net 3 are connected with the inner wall of the roller body 1 is designed with a sliding ring 7, the sliding ring 7 has a certain activity space and can slide a certain distance along the vertical chain 30 or the support column 25, so as to help remove the mixture adhered on the vertical chain 30 or the support column 25

[0046] The above description is only the preferred embodiment of the present application, and cannot limit the scope of the present application. Any equivalent changes and modifications made according to the patent application scope and the content of the specification should still be within the scope of the present application.
