Description

Technical Field

[0001] This utility model relates to an anti-adhesion recycling roller and its lifting plate structure. Background Art

[0002] Asphalt hot recycling equipment mainly uses a recycling drum to heat the recycled material, such as the asphalt recycling material heating equipment and heat energy utilization method disclosed in authorization announcement CN110280075B. During the heating process inside the drum, due to its inherent characteristics, the asphalt in the recycled material gradually melts as the temperature rises, and the fine particles and fine sand particles easily adhere to the inner wall of the drum, the lifting plates, and the lifting plate supports. Experiments show that the adhesion between the recycled asphalt and the steel plate is greatest when heated to 110 to 120°C. Therefore, during its flow heating process, the adhesion to the drum wall and lifting plates in this area is the most severe, requiring regular manual cleaning. Utility Model Content

[0003] The purpose of this invention is to provide an anti-adhesion recycling roller and its lifting plate structure to solve the problem of severe adhesion between heated asphalt and the roller wall and lifting plate.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A non-adhesive recycling drum lifting plate structure includes a lifting plate, two support seats and a cleaning chain. The support seats are used to fix the inner wall of the recycling drum, the lifting plate is fixed on the support seats, and the two ends of the cleaning chain are respectively movably sleeved on the two support seats.

[0006] Furthermore, the lifting plate is a bent plate, comprising a first plate body and a second plate body, at least one of the first plate body and the second plate body having a through hole.

[0007] Furthermore, the first plate and the second plate are bent at an angle of 100 to 130 degrees.

[0008] Furthermore, both the first plate and the second plate are provided with a plurality of through holes, which are elongated holes with their length direction along the width direction of the corresponding plate. The two support seats are arranged along the length direction of the first plate, and the first plate is fixed on the support seats.

[0009] Furthermore, the through holes are staggered along the length of the first plate.

[0010] Furthermore, the support base is made of a round tube, and a notch is provided on one side of the upper part of the round tube. A connecting plate is provided in the notch, and the lifting plate is fixed to the connecting plate by bolts.

[0011] Furthermore, the threaded portion of the bolt is located inside the circular tube.

[0012] An anti-adhesion recycling roller includes a cylinder body and a lifting plate structure as described in any of the above claims, wherein multiple lifting plate structures are provided and distributed circumferentially along the inner wall of the cylinder body.

[0013] The beneficial effects of this utility model are:

[0014] During the lifting process, fine particles in the recycled asphalt can flow out through the elongated holes on the lifting plate, reducing the residence time when the material is lifted to the high position of the drum and allowing it to quickly enter the high-temperature zone. The elongated holes on the lifting plate also reduce the adhesion between the recycled material and the steel plate. Compared to the traditional rake-tooth structure, it has higher strength and can lift large-diameter recycled material to form a better material curtain, facilitating heat exchange.

[0015] During the drum's rotation, the rings of the cleaning chain can move up and down at the circular tube section of the support base, removing the fine asphalt recycled material adhering to the support base; the chain section in the middle of the cleaning chain continuously beats and shakes against the drum wall, cleaning the recycled material adhering to the drum wall.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art are within the protection scope of the present utility model.

[0021] An embodiment of the anti-adhesion recycling drum lifting plate structure of this utility model:

[0022] like Figures 1-2As shown, a non-stick recycling drum lifting plate structure includes a lifting plate 1, two support seats 2 and a cleaning chain 3. The support seats 2 are used to fix the inner wall of the recycling drum, and the lifting plate 1 is fixed on the support seats 2.

[0023] The lifting plate 1 is a bent plate, including a first plate body 11 and a second plate body 12. The first plate body 11 and the second plate body 12 are bent at a 120-degree angle, which can also be 100 to 130 degrees in other embodiments. Two support seats 2 are arranged along the length direction of the first plate body 11, and the bottom of the first plate body 11 is fixed on the two support seats 2.

[0024] The support base 2 is made of a round tube with a notch on one side of the upper part. A connecting plate 5 is installed at the notch. The notch is formed by cutting off a section of the tube wall. The connecting plate 5 is welded to the notch. The lifting plate 1 is fixed to the connecting plate 5 by bolts 4. The connecting plate 5 provides a contact surface for the lifting plate 1 and has through holes for the bolts 4. The threaded part of the bolt 4 is located inside the round tube, so that the nut that mates with the bolt 4 is located inside the round tube, avoiding material snagging on the nut and the exposed bolt 4, and also reducing wear on the bolt 4 during use.

[0025] The support base 2 is made of round tube, which can reduce the adhesion of recycled materials.

[0026] Both the first plate 11 and the second plate 12 are provided with several through holes, which are elongated holes 13, with their length direction along the width direction of the corresponding plate. The through holes are staggered along the length direction of the first plate 11. During the lifting process, fine particles in the recycled asphalt can flow out through the elongated holes 13, reducing the residence time when the lifting plate 1 lifts the material to the high position of the drum, allowing it to quickly enter the high-temperature zone. The elongated holes 13 on the lifting plate 1 reduce the adhesion between the recycled material and the steel plate, allowing large-diameter stones to be easily washed away from the surface of the lifting plate 1. Compared to the traditional rake-tooth structure, it has higher strength, can lift large-diameter recycled material, forming a better material curtain, which is beneficial for heat exchange.

[0027] The cleaning chain 3 has two circular rings 31 at its ends, which are movably fitted onto two support seats 2, that is, onto the circular tube sections of the support seats 2. During the drum's rotation, the circular rings 31 can move up and down at the circular tube sections of the support seats 2, removing the asphalt recycling fines adhering to the support seats 2; the chain section in the middle continuously beats and shakes against the drum wall, cleaning the recycled material adhering to the drum wall.

[0028] like Figure 3 As shown, an anti-adhesion recycling roller includes a cylinder body 6 and a lifting plate structure. Multiple lifting plates are provided and distributed circumferentially along the inner wall of the cylinder body 6. The lifting plate structure is similar to... Figures 1-2 The structure shown will not be described in detail again. Figure 3The image shows a section of the recycling drum. By optimizing the structure of the lifting plates, the problem of severe adhesion between the existing drum wall and the lifting plates has been solved.
