Description

Technical Field

[0001] The utility model relates to the technical field of asphalt production, in particular to a roller type asphalt production device. Background Art

[0002] The drying drum is one of the main components of asphalt mixing equipment. Its main function is to heat and dry aggregate and heat the aggregate to the temperature required for high-quality asphalt mixture.

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0022] Please refer to 1-3, a drum-type asphalt production device includes an inclined bracket 1, on which a drying drum 2 is inclinedly arranged, the drying drum 2 is rotatably arranged on the inclined bracket 1 through a driving mechanism 3, a screen drum 4 is rotatably arranged inside the drying drum 2, and a plurality of storage hoppers 5 are arranged in an array on the screen drum 4.

[0023] Specifically, the driving mechanism 3 includes four friction rollers, which support the friction roller ring on the drying cylinder 2. The friction roller ring is driven by the reduction motor to rotate the friction roller, thereby realizing the rotation of the drying cylinder 2. The drying cylinder 2 is connected to the screen cylinder 4 through a bearing. The specific installation method and working principle of the driving mechanism 3 are common knowledge known to the staff in this field, and no further explanation is given here; refer to Figure 1 , the partition 21 is welded on the inner wall of the drying cylinder 2, and the heating mechanism 6 is arranged outside the drying cylinder 2. The heating mechanism 6 can be sleeved outside the drying cylinder 2, or it can be arranged inside the drying cylinder 2 in the form of a heating source. The purpose is to dry and heat the mixture in the drying cylinder 2. The specific installation method is common knowledge known to those skilled in the art and will not be explained in detail here. The utility model can screen out large pieces of the mixture by rotating the screen cylinder 4 inside the drying cylinder 2 to improve the quality of the mixture. At the same time, through the setting of the storage hopper 5, the partition 21 inside the drying cylinder 2 brings the mixture to a high place and drops it. A part of the mixture slides into the storage hopper 5. As the screen cylinder 4 rotates, the mixture in the storage hopper 5 is brought to the other side of the drying cylinder 2 and poured out, so that the mixture between the partitions 21 in the drying cylinder 2 is evenly distributed to improve the mixing efficiency of the mixture.

[0024] Furthermore, the screen drum 4 includes a cylinder body 41 , on which a plurality of round rods 42 are arranged in an array.

[0025] Specifically, refer to Figure 2 The gap formed between two adjacent round rods 42 is used to screen the mixture. As the screen drum 4 rotates, the mixture falls from between the two round rods 42, while large pieces of the mixture are retained in the screen drum 4 and discharged as the screen drum 4 rotates. At the same time, due to the arrangement of a plurality of round rods 42, when the mixture is brought to a high place and slides down, the mixture hits the round rods 42, which has a breaking effect on the mixture, thereby increasing the internal space of the mixture and making it easier to dry, thereby improving the baking efficiency of the mixture.

[0026] Furthermore, a plurality of groups of reinforcing ribs 43 are disposed on the plurality of round rods 42 .

[0027] Specifically, refer to Figure 2 By fixing three groups of reinforcing ribs 43 outside a plurality of round rods 42, the stability of the round rods 42 is enhanced, and the practicability of the device is improved.

[0028] Furthermore, the storage hopper 5 is fixedly connected to the reinforcing rib 43 , and a gap is left between two adjacent storage hoppers 5 in the axial direction of the screen drum 4 .

[0029] Specifically, refer to Figure 2 There is a gap between adjacent storage hoppers 5, and the size of the gap is not enough to accommodate the storage hopper 5, so as to ensure that the mixed material intercepted by the storage hopper 5 and the uninterrupted mixed material are close to each other, and to ensure that the weight of the mixed material retained between adjacent partitions 21 is not much different, which is greatly beneficial to the drying of the mixed material.

[0030] Furthermore, an overflow chute 51 is provided on the storage hopper 5 .

[0031] Specifically, by providing an overflow groove 51 on the storage hopper 5, the mixed material overflowing from the storage hopper 5 overflows from the overflow groove 51, and the overflowed mixed material hits the round rod 42, thereby expanding the heating area of ​​the mixed material, thereby improving the baking efficiency.

[0032] Furthermore, a slag discharge port 411 is provided on the cylinder body 41 .

[0033] Specifically, as the cylinder 41 rotates and is arranged tilted, the large pieces of mixed material in the cylinder 41 slide to one side of the screen cylinder 4, and the outlet direction of the slag discharge port 411 changes as the cylinder 41 rotates. When the slag discharge port 411 is directed vertically downward, the mixed material in the cylinder 41 is discharged; the rotation of the cylinder 41 is driven directly by a motor or, like the drying cylinder 2, by a friction device.

[0034] In this utility model, reference Figures 1 to 3 First, the mixed material is introduced from the inlet of the cylinder 41. After passing through the rotating cylinder 41, the mixed material of suitable size is discharged from between the two round rods 42 and enters the drying cylinder 2, and the mixed material is separated into different areas by the partition 21 for baking. Then, during the rotation of the drying cylinder 2, the mixed material is brought to a high place and poured. Part of the mixed material is caught by the storage hopper 5, and the other part hits the round rod 42 and is dispersed and scattered. The mixed material overflowing the storage hopper 5 overflows through the overflow trough 51. As the screen cylinder 4 continues to rotate, the mixed material in the storage hopper 5 is poured to the other side of the drying cylinder 2, passes through the round rod 42, and is scattered in the partition 21. Then the above operation is repeated until the mixed material is dried and heated to a specified temperature and then discharged from the discharge port of the drying cylinder 2.

[0035] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
