Description

Technical Field

[0001] This utility model relates to the field of sintering flux production technology, and in particular to a device for striking the drum wall of a rotary dryer to prevent material from sticking. Background Technology

[0002] Sintered flux is an important component of welding materials, and its production process typically includes key steps such as batching, granulation, drying, and sintering. Among these, the drying process is crucial to the final performance and quality of the flux, and rotary drum dryers are commonly used for this purpose.

[0003] During the drying process, flux particles with a certain level of moisture are added from the front (feeding end) of the rotary dryer and gradually move towards the rear as the drum rotates. During this process, hot air exchanges heat with the material to remove moisture. However, because the newly added flux particles have a high moisture content and a certain degree of stickiness, some particles adhere to the inner wall of the drum, especially on the front section, as the drum rotates and rises and falls. If these adhered materials are not cleaned in time, they will accumulate and thicken, forming a stubborn crust layer. This will significantly reduce the effective drying space and heat transfer efficiency of the drum.

[0004] To address the aforementioned problems, existing technologies typically employ manual cleaning during shutdown. This involves periodically stopping the dryer and having operators enter the drum to knock and scrape away debris. This method is not only labor-intensive and inefficient, but more seriously, it requires production interruption, reducing the equipment's effective operating rate and impacting overall production efficiency.

[0005] Therefore, there is an urgent need in this field for a device that can automatically remove deposits adhering to the inner wall of a rotary dryer online, in order to ensure the continuity, stability and economy of production. Summary of the Invention

[0006] This utility model addresses the shortcomings of existing technologies by providing a device for striking the drum wall of a rotary dryer to prevent material from sticking.

[0007] This utility model is achieved through the following technical solution: a device for preventing material sticking to the drum wall of a rotary dryer, comprising multiple sets of climbing structures arranged sequentially along the axial direction of the rotary dryer on the outer wall of the front section of the dryer. Each set of climbing structures includes multiple climbing blocks, each climbing block being fixedly installed on the outer wall of the drum. Each climbing block has a climbing arc surface and a vertical descending surface. The multiple climbing blocks are distributed circumferentially along the drum and face the same direction. A mounting frame is erected above the rotary dryer, and multiple sets of striking mechanisms corresponding to each set of climbing structures are installed on the crossbeam of the mounting frame.

[0008] Preferably, the mounting frame includes two portal frames, which are respectively located at both ends of the front section of the rotary dryer. The two portal frames are connected by a crossbeam, through which the rotary dryer passes. The crossbeam is located above the rotary dryer. The lower end of each portal frame is fixed to the ground.

[0009] Preferably, each striking mechanism includes a guide rod that runs through the crossbeam and is vertically arranged. An upper limit block is fixed to the upper end of the guide rod, and a lower limit block is fixed to the lower end of the guide rod. A spring is sleeved on the guide rod, and the spring is located between the lower limit block and the crossbeam. A steel striking roller is detachably installed on the lower limit block.

[0010] Preferably, the steel striking roller is rotatably mounted on the wheel frame, the wheel frame is fixedly mounted on the mounting plate, and the mounting plate is connected and fixed to the lower limit block by bolts and nuts.

[0011] Preferably, three sets of climbing structures are provided on the outer wall of the front section of the rotary drum dryer, and three sets of striking mechanisms are installed on the crossbeam of the mounting frame, with each set of striking mechanisms corresponding to one set of climbing structures.

[0012] The beneficial effects of this utility model are as follows: 1. This invention ingeniously combines the striking action with the rotation of the drum itself, achieving continuous and automatic striking of the inner wall of the front section during the drying process. It effectively shakes off adhering materials without requiring machine shutdown, completely avoiding production interruptions caused by downtime for cleaning, and significantly improving equipment utilization and overall production efficiency.

[0013] 2. The core innovation of this device lies in its driving mechanism. It eliminates the need for an independent power source (such as a motor), instead directly utilizing the kinetic energy of the rotating drum as the driving force. A simple and reliable mechanical structure converts the rotational motion into a vertical lifting and striking motion. This design is not only simple in structure and low in manufacturing cost, but also achieves energy recycling, resulting in significant energy savings.

[0014] 3. The striking frequency of the device is directly proportional to the rotational speed of the drum. When the material inside the drum is heavily adhered or the operating load may increase, even a slight change in rotational speed will directly lead to an increase in the number of strikes per unit time, thus creating an adaptive cleaning effect of "the more adhered, the more strikes," ensuring the timeliness and effectiveness of cleaning and preventing the accumulation of the adhered layer.

[0015] 4. By continuously keeping the inner wall clean, the effective drying space and optimal heat exchange efficiency of the rotary drum are ensured. This results in more uniform heating of the flux particles, fundamentally guaranteeing the drying quality. Attached Figure Description

[0017] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to describe the solution.

[0018] like Figure 1-5 As shown, this utility model includes multiple sets of climbing structures installed on the outer wall of the front section of the rotary dryer 1. These climbing structures are arranged sequentially along the axial direction of the rotary dryer 1. Each climbing structure includes multiple climbing blocks 2, each of which is fixedly installed on the outer wall of the rotary drum. Each climbing block 2 has a climbing arc surface 11 and a vertical descending surface 12. The multiple climbing blocks 2 are distributed circumferentially along the rotary drum and face the same direction. A mounting frame is erected above the rotary dryer 1, and multiple striking mechanisms corresponding to each climbing structure are installed on the crossbeam 4 of the mounting frame.

[0019] In this embodiment, the mounting frame includes two portal frames 3, which are respectively located at both ends of the front section of the rotary dryer 1. The two portal frames 3 are connected by a crossbeam 4, through which the rotary dryer 1 passes. The crossbeam 4 is located above the rotary dryer 1. The lower end of each portal frame 3 is fixed to the ground.

[0020] In this embodiment, each striking mechanism includes a guide rod 5 that passes through the crossbeam 4 and is vertically arranged. An upper limit block is fixed to the upper end of the guide rod 5, and a lower limit block 9 is fixed to the lower end of the guide rod 5. A spring 10 is sleeved on the guide rod 5, and the spring 10 is located between the lower limit block 9 and the crossbeam 4. A steel striking roller 6 is detachably installed on the lower limit block 9.

[0021] Furthermore, the steel striking roller 6 is rotatably mounted on the wheel frame 7, the wheel frame 7 is fixedly mounted on the mounting plate 8, and the mounting plate 8 is connected and fixed to the lower limit block 9 by bolts and nuts.

[0022] In this embodiment, three sets of climbing structures are provided on the outer wall of the front section of the rotary dryer 1, and three sets of striking mechanisms are installed on the crossbeam 4 of the mounting frame, with each set of striking mechanisms corresponding to a set of climbing structures.

[0023] In practical use, the rotary dryer 1 rotates, driving multiple sets of climbing structures to rotate synchronously. When the climbing block 2 contacts the steel striking roller 6, the rotation of the drum causes the steel striking roller 6 to roll and climb along the climbing arc surface 11, reaching the highest point of the climbing arc surface 11. During the climbing process, the spring 10 is compressed. As the drum rotates further, the steel striking roller 6 loses the support of the climbing arc surface 11, the spring 10 relaxes, and under the force of the spring 10, the steel striking roller 6 strikes heavily against the outer wall of the drum. Under the action of the striking force, the material attached to the inner wall of the drum can be shaken off.

[0024] This invention ingeniously combines the striking action with the rotation of the drum itself, achieving continuous and automatic striking of the inner wall of the front section during the drying process. It effectively shakes off adhering materials without requiring machine shutdown, completely avoiding production interruptions caused by cleaning, and significantly improving equipment utilization and overall production efficiency.
