Description

Technical Field

[0001] The utility model relates to the field of drying equipment, in particular to a rotary drying device for road and bridge construction materials. Background Art

[0002] The rotary drying equipment uses a rotating cylindrical container to dry the material placed inside it. The material can flow in from the inlet and out from the outlet continuously, forming a continuous drying process. Among them, in the drying process of the above equipment, there are generally two factors that determine the dryness of the material (the degree of drying of the material), one is the angle of the disturber 2 set in the rotary drum 1, and the other is the rotation speed of the rotary drum 1.

[0003] When the angle of the spoiler 2 is an acute angle R with the linear direction of rotation of the rotary drum 1, the material turning effect is good and the material drying can be accelerated; when the angle of the spoiler 2 is an obtuse angle with the linear direction of rotation of the rotary drum 1, the opposite is true. In the existing structure, the spoiler 2 is fixedly connected to the wall of the rotary drum 1, that is, the angle of the spoiler 2 is fixed, and it is impossible to adaptively adjust the angle of the spoiler 2 according to the required drying degree of the material.

[0021] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0022] See also Figure 1 , Figure 4 The utility model provides a rotary drying device for road and bridge construction materials, which includes a rotary drum 1 and an interference plate 2 installed on the wall of the rotary drum 1; the rotary drum 1 is mounted on a rotary support unit 3, and the axis of the rotary drum 1 after installation is set at an angle A with the horizontal plane; the rotary support unit includes a rotary drive frame 11 and a rotary driven frame 12, and the rotary drive frame 11 drives the rotary drum 1 to rotate through a gear structure (the structure of the rotary drive frame 11 and the rotary driven frame 12 and the connection method with the rotary drum 1 are both existing structures). One end of the rotary drum 1 is the feed end, and the other end is the discharge end. At the same time, a dryer is installed at one end (generally on the discharge end side). During the material drying process, the material is continuously transported from the feed end to the equipment. As the rotary drum 1 rotates, the interference plate 2 turns the material over and dries the material in cooperation with the drying airflow blown out by the dryer. Finally, the dried material flows out from the discharge end.

[0023] See also Figure 2 and Figure 3 , the connecting end of the spoiler 2 is provided with a rotating shaft 21; the wall of the rotary drum 1 is provided with a mounting hole for installing the rotating shaft 21. Specifically, the working surface of the spoiler 2 is parallel to the axis of the rotary drum 1, and the rotating shaft 21 is arranged at the side end of the working surface; the spoiler 2 can swing around the axis of the rotating shaft 21 within a predetermined angle H; an adjusting component for positioning the spoiler 2 to the required working angle is installed in the rotary drum 1. When the drying degree of the material needs to be regulated and improved, the angle of the spoiler 2 is adjusted to an acute angle with the linear direction of the rotation of the rotary drum 1 through the adjusting component. At this angle, the spoiler 2 can carry more materials and the turning effect is better. When the drying degree needs to be reduced, the angle of the spoiler 2 is adjusted to an obtuse angle with the linear direction of the rotation of the rotary drum 1 through the adjusting component. At this angle, the spoiler 2 has a limited material carrying capacity (the material is easy to slide off the spoiler 2), and the turning effect is reduced.

[0024] See also Figure 3 , Figure 5 and Figure 6 , wherein, if the interference plate 2 is distributed in a ring shape; the adjustment component includes a drive sleeve 3 coaxially sleeved in the rotating drum 1 and capable of rotating relative to the rotating drum 1; the drive sleeve 3 is provided with a through hole 4 for the interference plate 2 to pass through; there is a gap between the through hole 4 and the interference plate 2; the drive sleeve 3 is driven by a drive component to rotate within a predetermined angle. When the drive sleeve 3 rotates relative to the rotating drum 1 at a predetermined angle, it will further drive the interference plate 2 to swing at a predetermined angle (the rotating drive sleeve 3 drives the interference plate 2 to swing by the side wall of the through hole 4, Figure 3 As shown), the working state of the spoiler 2 is changed. The driving sleeve 3 can drive multiple spoilers 2, ensuring the working integration effect of the driving components.

[0025] Preferably, the inner wall of the rotary drum 1 is provided with an embedding groove 10 for installing the drive sleeve 3, and the inner wall of the drive sleeve 3 installed in the embedding groove 10 is flush with the inner wall of the rotary drum 1 to prevent the drive sleeve 3 from blocking the material.

[0026] See also Figure 1 , Figure 5 and Figure 7 The driving assembly of the utility model includes an inclined groove 31 or a spiral groove (specifically, the inclined groove 31 is selected in this embodiment) arranged on the inner wall of the driving sleeve 3, a driving rod 5 that moves along the axial direction of the rotating drum 1, and a connecting rod 6 that is arranged on the driving rod 5 and extends into the inclined groove 31 or the spiral groove. The end of the driving rod 5 is connected to a driver (a cylinder is sufficient), and the driving rod 5 is connected to the output end of the driver through a sleeve 00, and the two ends of the sleeve 00 are respectively connected to the output end of the driving rod 5 or the driver through bearings 01. Through the above structure, multiple groups of driving sleeves 3 can be operated, which increases the integration effect of the equipment. During driving, the driver drives the driving rod 5 to move (move along the axial direction of the rotating drum 1), and the moving driving rod 5 drives the rotating drum 1 to rotate through the cooperation of the connecting rod 6 and the inclined groove 31.

[0027] Furthermore, the driving rod 5 of the utility model forms a linkage structure with the rotary driving frame 11 through a belt transmission structure. The belt structure can be used to position the rotation of the driving rod 5, so that the rotation speed of the driving rod 5 is almost synchronized with the rotary drum 1, thereby avoiding the self-rotation (the driving rod 5 rotates around the axis of the rotary drum 1) when the driving rod 5 drives the driving sleeve 3 to rotate, which further causes the driving sleeve 3 to be unable to drive normally.

[0028] In addition, the groove wall of the inclined groove 31 or spiral groove and the hole wall of the through hole 4 of the utility model are provided with a blocking structure to prevent materials from entering the inside thereof, and the blocking structure is used to prevent materials from entering the connection between the driving sleeve 3 and the spoiler 2, which will not only damage the equipment, but also jam the equipment and cause the equipment to fail to work properly. The blocking structure is a hard brush structure.

[0029] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field can make various corresponding changes and deformations based on the present invention, but these corresponding changes and deformations should all fall within the scope of protection of the claims attached to the present invention.
