Description

Technical Field

[0001] This application relates to the field of drying equipment technology, specifically to a paddle structure for a drying equipment. Background Technology

[0002] Paddle dryers are a type of indirect heating drying equipment widely used in industrial fields, mainly for processing high-humidity, viscous, or heat-sensitive materials.

[0003] Paddle dryers typically consist of paddles, a shell, a heating device, and a transmission system. During the rotation of the paddles, the material is heated evenly, and the moisture evaporates rapidly, thus completing the drying process. For example, Chinese utility model patent CN214746968U discloses a hollow paddle dryer. In its technical solution, the hollow paddle structure enhances the heat transfer efficiency, effectively improves the drying effect, and solves the problems of high energy consumption and low efficiency of traditional paddle dryers.

[0004] However, in the implementation of the above technical solution, since the blades are fixedly connected to the hollow blade shaft, when a blade needs maintenance or replacement, the entire blade shaft must be disassembled and the machine must be stopped, resulting in high maintenance costs, long downtime, and many limitations in use.

[0005] Therefore, it is necessary to provide a paddle structure for a drying device to solve the above problems.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0033] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0035] Example 1: As Figure 1 As shown, this application provides a paddle structure for a drying device. The structure is applied in a drying device, which includes a base 1, which serves as the support for the entire drying device. A drying cylinder 2 is fixedly installed on the base 1. The drying cylinder 2 has a drying chamber inside, and two sets of stirring mechanisms 3 are provided inside the drying chamber. The stirring mechanisms 3 are used to stir and dry the material in the drying chamber.

[0036] The stirring mechanism 3 includes a bearing 31, which is fixedly installed on the base 1. A hollow rotating shaft 32 is rotatably connected inside the bearing 31. The hollow rotating shaft 32 passes through the entire drying cylinder 2, and the other end of the hollow rotating shaft 32 is connected to a drive mechanism 4. The drive mechanism 4 drives the hollow rotating shaft 32 to rotate.

[0037] A stirring blade 33 is provided on the hollow rotating shaft 32. The stirring blade 33 is arranged along the circumference of the hollow rotating shaft 32, and there are at least two stirring blades 33. The two stirring blades 33 are distributed opposite each other. When the hollow rotating shaft 32 rotates, the stirring blades 33 can stir the material in the stirring chamber.

[0038] To dry the material in the mixing chamber, such as Figure 1 As shown, the other end of the bearing 31 is also provided with an air inlet pipe 34. The side of the bearing 31 has a convex ring 311, and the air inlet pipe 34 is sleeved on the convex ring 311. The air inlet pipe 34 is used to connect to an external heat source and introduce the hot air generated by the external heat source into the hollow rotating shaft 32. At the same time, the hollow rotating shaft 32 is provided with multiple sets of air outlets 35. When the hot air enters the hollow rotating shaft 32, it will enter the drying chamber through the air outlets 35, thereby drying the material during the stirring process. The external heat source can be a steam generator, and specific details can be found in the prior art.

[0039] To reduce the leakage of hot air and affect the drying effect, a partition ring 312 is also provided inside the bearing seat 31. The inner side of the partition ring 312 is rotatably connected to the hollow rotating shaft 32. After hot air enters from the convex ring 311 of the bearing seat 31, the leakage of hot air is reduced due to the blocking effect of the partition ring 312, thereby improving the drying effect.

[0040] The drive mechanism 4 includes a drive motor 41 and a gear set 42 disposed at one end of a hollow rotating shaft 32. The output end of the drive motor 41 is connected to the gear set 42 for transmission. The drive motor 41 can drive the gear set 42 to rotate, thereby driving the hollow rotating shaft 32 to rotate, thus completing the stirring and drying of the material.

[0041] like Figure 3 As shown, in order to prevent dead corners from forming during the mixing process, which would cause some material to accumulate and become ineffective, a conical surface 21 is provided at the bottom of the drying chamber. This conical surface 21 can guide the material to move to both sides of the two sets of mixing mechanisms 3, preventing the dead corner area between the two sets of mixing mechanisms 3 from being ineffectively mixed. In addition, the conical surface 21 has a protrusion 22 in the middle, which can prevent material accumulation and divert the material, thereby achieving uniform drying.

[0042] Example 2: Based on Example 1 above, since the stirring blade 33 is fixedly installed with the hollow rotating shaft 32, the entire stirring mechanism 3 needs to be disassembled when maintenance or replacement is required, which is cumbersome. Therefore, in this example, the following improvements are made to address this problem:

[0043] like Figure 2As shown, the stirring blade 33 is no longer directly fixed to the hollow rotating shaft 32, but is provided with a connecting cylinder 36. The connecting cylinder 36 is composed of two half-cylinders, and each half-cylinder is provided with a threaded hole 37. A bolt 38 is provided in the threaded hole 37. The hollow rotating shaft 32 is provided with the same threaded hole 37. The connecting cylinder 36 and the hollow rotating shaft 32 are fixed by the bolt 38. Since each half-cylinder is provided with a threaded hole 37, partial installation or partial disassembly can be achieved. The stirring blade 33 is fixedly installed on the connecting cylinder 36. When the stirring blade 33 needs to be repaired or replaced, it is only necessary to loosen the bolt 38 on the corresponding half-cylinder. There is no need to disassemble the entire device, which is convenient and quick.

[0044] Furthermore, based on the above, multiple sets of stirring blades 33 can be arranged on the connecting cylinder 36. When facing different materials, the number of stirring blades 33 can be quickly changed to meet different stirring needs and improve the adaptability and working efficiency of the equipment.

[0045] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
