Description

Technical Field

[0001] The utility model relates to the field of asphalt preparation, in particular to a recycled material drying drum. Background Art

[0002] Asphalt is a viscous, black, semi-solid or solid hydrocarbon substance refined from natural petroleum or extracted from asphalt ore. It mainly consists of elements such as carbon, hydrogen, and small amounts of nitrogen, oxygen, and sulfur. Asphalt is in a semi-solid or high-viscosity state at room temperature, but becomes more fluid when heated. In the preparation process of asphalt mixture, the filler is usually dried, but even so, the recycled material may still contain a certain amount of moisture. The recycled material drying drum can completely remove the moisture in the recycled material through heating and wind action to ensure that the dryness of the recycled material meets the requirements.

[0003] After retrieval, a material lifting structure of a drying drum is disclosed in the publication number: CN209759957U, which includes a base plate, a connecting piece, a plurality of material lifting blades and a plurality of loop chains. One end of the connecting piece is connected to the base plate, and the other end is connected to the inner wall of the drum; the plurality of material lifting blades are arranged at intervals on the top surface of the base plate; the plurality of loop chains are arranged at intervals at the bottom of the base plate. The loop chain is composed of a plurality of chain links in series. The chain link at the top of the loop chain is connected to the bottom of the base plate, and the chain link at the bottom of the loop chain can be in frictional contact with the inner wall of the drying drum. During operation, the loop chain swings as the drying drum rotates, and the surrounding materials are not easily adhered to the inner wall of the drum and the material lifting blades. Moreover, the chain link at the bottom of the loop chain can be in frictional contact with the inner wall of the drum. When the loop chain rotates to near the lowest position of the drum, it will have frictional contact with the inner wall of the drum to remove the sticky material on the inner wall of the drum.

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] Referring to Figures 1 - 3 , an embodiment provided by the present invention: A recycled material drying drum includes a material barrel 1, a motor 2 is fixedly connected to one side of the material barrel 1, the output end of the motor 2 is fixedly connected to a cross bar 3, a first support rod 4 is fixedly connected to the outer wall of the cross bar 3, a mounting hole 5 is opened inside the first support rod 4, a mounting groove 6 is opened inside the first support rod 4, a mounting block 7 is arranged on the outer wall of the first support rod 4, the outer wall of the mounting block 7 is slidably connected inside the mounting groove 6, a first limiting plate 9 is slidably connected inside the mounting block 7, a pin 8 is fixedly connected inside the first limiting plate 9, the outer wall of the pin 8 is slidably connected inside the mounting hole 5, a reset assembly is arranged on the outer wall of the pin 8, one end of the pin 8 is fixedly connected to a pinch block 10, a chain 17 is fixedly connected to the top of the mounting block 7, and the reset assembly includes a first spring 11, the first spring 11 is sleeved on the outer wall of the pin 8, one end of the first spring 11 is fixedly connected to one side of the first limiting plate 9, and the other end of the first spring 11 is fixedly connected to the inside of the mounting block 7;

[0040] Specifically, when the endless chain 17 needs to be replaced due to wear or other reasons, the operator can easily complete it by following a few simple steps. First, by pinching the pinch block 10, the pin 8 can be easily pulled out from the mounting hole 5. This design takes into account the humanized operation requirements, making the process of pulling out the pin 8 easy and labor-saving. After the pin 8 is separated from the mounting hole 5, the mounting block 7 can be removed from the support rod one 4. This step is also simple and clear, without the need for complex tools or skills. Next, install the new endless chain 17. The new endless chain 17 is connected to the support rod one 4 through the mounting block 7. The mounting block 7 is accurately installed on the support rod one 4 through the mounting groove 6, ensuring the stability and reliability of the endless chain 17. Subsequently, the pin 8 is slid into the interior of the mounting hole 5 for connection. During this process, the pin 8 is limited inside the mounting block 7 by the limiting plate one 9. This design not only ensures the accurate positioning of the pin 8 but also prevents the accidental detachment of the pin 8 during use. In addition, the tension support of the first spring 11 also plays a key role. The tension of the first spring 11 pushes the limiting plate one 9, thereby driving the pin 8 to insert into the mounting hole 5, making it difficult for the pin 8 to slide out. This design not only enhances the stability of the connection but also reduces the safety risk caused by the detachment of the pin 8.

[0041] Refer to Figure 4 and Figure 5

[0042] ​Specifically, during operation, the output end of the motor 2 drives the cross bar 3 to rotate. The ingenious design of the cross bar 3 lies in its ability to cooperate with the support rod one 4, enabling the endless chain 17 to efficiently agitate on the inner wall of the material barrel 1. This agitation action not only helps with the uniform mixing of materials but also prevents the materials from sticking and clogging inside the material barrel. At the same time, the cross bar 3 also drives the scraper 14 on the support rod two 12 to scrape and clean the inner wall of the material barrel 1. This design aims to prevent the recycled material from adhering to the inner wall of the material barrel, thereby ensuring the smooth progress of the production process. To ensure the stability and effectiveness of the scraper 14 during the scraping process, the device also limits the position of the scraper 14 through the limit plate two 13. In addition, the scraper 14 is supported by the tension of the second spring 16, enabling the scraper 14 to closely adhere to the inner wall of the material barrel but not get stuck by the recycled material that cannot be cleaned. It is worth mentioning that the design of this device not only considers the effects of material mixing and cleaning but also fully takes into account the durability and maintenance convenience of the equipment. For example, the material selection of the scraper 14, the precise design of the limit plate two 13, and the reasonable configuration of the second spring 16 are all to ensure that the equipment can maintain stable and reliable performance during long-term operation.

[0043] Working principle: When using this recycled material drying drum, when it is necessary to disassemble the endless chain 17 for replacement, simply pull out the pin 8 through the pinch block 10, so that the pin 8 is separated from the mounting hole 5, and then remove the mounting block 7. Subsequently, to install the new endless chain 17, just install the mounting block 7 on the support rod one 4 through the mounting groove 6, and then slide the pin 8 into the interior of the mounting hole 5 for connection. The pin 8 is limited inside the mounting block 7 by the limit plate one 9 and supported by the tension of the first spring 11, so that the tension of the first spring 11 drives the limit plate one 9 to drive the pin 8 to insert into the mounting hole 5 and is not easy to slide out. Subsequently, during operation, the output end of the motor 2 drives the cross bar 3 to rotate. The cross bar 3 drives the endless chain 17 to agitate the inner wall of the material barrel 1 through the support rod one 4. At the same time, the cross bar 3 drives the scraper 14 on the support rod two 12 to scrape and clean the inner wall of the material barrel 1 to prevent the recycled material from adhering inside the material barrel 1. The scraper 14 is limited inside the support rod two 12 by the limit plate two 13 and supported by the tension of the second spring 16, enabling the scraper 14 to closely adhere to the inner wall of the material barrel 1 and not get stuck by the recycled material that cannot be cleaned.

[0044] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
