[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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a novel self-cleaning blade for a recycling drum, comprising a support plate 3 that securely connects a bent round steel bar 1 on its upper surface and a chain connecting plate 4 on its lower surface, enhancing the overall structural strength. The bent round steel bar 1 is fixedly connected to the upper surface of the support plate 3, and multiple bent round steel bars 1 form a special rake-shaped structure. When the recycling drum rotates, this structure effectively lifts the recycled material, causing it to form a material curtain within the drum, achieving sufficient heat exchange between the recycled material and hot air, improving drying efficiency, and reducing the adhesion of recycled material to the blades. A chain connecting plate 4 is fixedly connected to the lower surface of the support plate 3. A bolt, nut, and washer 6 is provided on one side of the outer wall of the chain connecting plate 4, which not only connects the chain connecting plate 4 to the drum fixing plate 5 but also provides a connection for the blades. The rotation of the blades allows for rotation within a certain angle range, which helps achieve the self-cleaning function. A chain body 2 is provided on one side of the outer wall of the bolt, nut, and washer 6. During the rotation of the drum, the chain body 2 moves with the chain connecting plate 4 and swings back and forth using the relatively loose connection characteristics to scrape off the recycled material adhering to the wall of the recycling drum, keeping the drum wall clean, reducing the adverse effects of adhesion on equipment operation, and improving the stability of equipment operation. A connecting component for enabling the bent round steel 1 to rotate is installed inside the chain connecting plate 4. The connecting component includes a cylinder fixing plate 5, which is used to connect to the inner wall of the hot recycling drying drum. The bolt, nut, and washer 6 is slidably connected inside the cylinder fixing plate 5, and the chain connecting plate 4 is fixedly connected to one side of the outer wall of the bolt, nut, and washer 6.

[0022] Reference Figure 1 , Figure 2 and Figure 3, multiple bending round steel 1 self-cleaning blade group, multiple bending round steel 1 group shape is rake type, by its unique shape effectively improve the reclaimed material, form material curtain, make the reclaimed material fully contact with hot air to realize heat exchange, achieve the purpose of drying, while reducing its own regeneration material adhesion, chain body 2 for scraping the regeneration drum wall adhesion of the regeneration material, in the drum rotation, chain body 2 because of relatively loose connection can swing back and forth, its swing track covers the wall, using mechanical action to remove the adhesion of the regeneration material, keep the wall clean, bolt nut washer 6 for connecting chain body 2 and chain connecting plate 4, support plate 3 for enhancing the connection strength of the structure, chain connecting plate 4 play the role of power transmission and movement, cylinder fixed plate 5 for connecting and bearing the blade working load, it is welded to the inner wall of the drum, provides the installation basis for the blade, ensures the stability of the blade position.

[0023] Working principle: when the regeneration drum starts to produce rotation, the rake-shaped blade composed of multiple bent round steels 1 moves with the drum, and due to the rake-shaped structure formed by the specific arrangement of multiple bent round steels 1, the regeneration material can be effectively lifted during rotation, so that the regeneration material forms a curtain in the drum, and in this process, the regeneration material is continuously lifted and falls, and fully contacts with hot air to achieve efficient heat exchange, and the hot air transmits heat to the regeneration material to increase the temperature of the regeneration material to achieve the purpose of drying; at the same time, the chain body 2 installed on the chain connecting plate 4 on the lower surface of the support plate 3 moves with the drum, and due to the relatively loose connection, it can swing back and forth under the action of gravity and centrifugal force generated by the rotation of the drum, and in the swinging process, the swinging track of the chain covers the part of the drum wall, and when it contacts with the drum wall, it scrapes the regeneration material adhered to the drum wall by using its own mechanical action, so that the adhesion of the regeneration material on the drum wall is effectively reduced, the drum wall is relatively clean, and the operation stability of the equipment is improved; then, the whole self-cleaning blade is connected with the drum body fixed plate 5 through bolt-nut washer 6, and this connection mode enables the blade to rotate freely within a certain angle range, and under the action of the impact force during the production rotation of the regeneration drum, the blade can rotate freely within a certain angle range, and the vibration effect generated by the rotation can loosen and fall the regeneration material adhered to the blade, so that the cleaning of the regeneration material adhered to the blade is realized, and through this function, the working efficiency of the blade during long-term operation is ensured, the influence of the adhesion of the regeneration material on the function of the blade is reduced, and the service life of the blade is prolonged; finally, the support plate 3 plays a key role in enhancing the connection strength of the structure, and it firmly connects the bent round steel 1 on the upper surface and the chain connecting plate 4 on the lower surface together to form an integral structure, and when the bent round steel 1 is subjected to the force of the regeneration material during the operation of the blade, the support plate 3 can effectively transmit the force to the chain connecting plate 4 and the whole blade structure, and at the same time, the chain connecting plate 4 not only connects the chain body 2, but also is fixed by welding with the support plate 3 and connected with the drum body fixed plate 5, so that the blade can realize the overall movement and function.
