[0002] The raw material made from phenolic plastic foam can be used to make molecular sieves. After crushing, the raw material needs to undergo pre-treatment processes such as drying and cooling. At present, most manufacturers use horizontal dryers for drying, but the cooling process mostly uses room temperature cooling, which is time-consuming and inefficient. In this regard, this paper proposes a nitrogen cooling unit that can be connected to a horizontal dryer to cool the dried material in a timely manner. Utility Model Content

[0023] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.
[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
[0025] The specific embodiments of this utility model are described below with reference to the accompanying drawings.
[0026] Example 1
[0027] This embodiment proposes a nitrogen cooling unit for the dried material; please refer to [link / reference]. Figures 1-3The nitrogen cooling unit for the dried material includes a drum 1 connected to the outlet of the horizontal dryer via a flange 2. The inner wall of the drum 1 has several spirally arranged ribs 10. The outer side of the drum 1 also has a supporting ring 3, which needs to contact the moving structure. At the other end of the drum 1 is a cover 5, which is bolted to a bearing 4. The bearing 4 surrounds the drum 1, allowing the drum 1 to rotate relative to the cover 5 (the cover 5 is fixed by a bracket). The bottom of the cover 5 is also connected to a material pipe 6, which discharges the dried material pushed out by the rotating drum 1.
[0028] Please see Figure 2 An insert 7 is provided inside the cylinder cover 5. Please refer to [link / reference]. Figure 3 The insert 7 is located below the axis of the roller 1. To further explain, there are multiple first cooling pipes 11 inside the roller 1. The first cooling pipes 11 are preferably U-shaped pipes. The first cooling pipes 11 are arranged in the insert 7 around the axis of the insert 7.
[0029] In this embodiment, both ports of the first cooling pipe 11 are located within the insert 7. Please refer to [link / reference]. Figure 1 The insert 7 is equipped with a first valve 8 and a second valve 9. The first valve 8 is connected to the inlet of all the first cooling pipes 11, and the second valve 9 is connected to the outlet of all the first cooling pipes 11. In this way, nitrogen gas is introduced into the first cooling pipes 11 and connected to the horizontal dryer drum 1, so that the drying material entering the drum 1 can fully contact the first cooling pipes 11 during the rotation of the drum 1, thereby achieving the effect of cooling and reducing temperature.
[0030] Example 2
[0031] This embodiment proposes a nitrogen cooling unit for the dried material; please refer to [link / reference]. Figure 1 , Figure 4 and Figure 5 The nitrogen cooling unit for the dried material includes a drum 1 connected to the outlet of the horizontal dryer via a flange 2. The inner wall of the drum 1 has several spirally arranged ribs 10. The outer side of the drum 1 also has a supporting ring 3, which needs to contact the moving structure. At the other end of the drum 1 is a cover 5, which is bolted to a bearing 4. The bearing 4 surrounds the drum 1, allowing the drum 1 to rotate relative to the cover 5 (the cover 5 is fixed by a bracket). The bottom of the cover 5 is also connected to a material pipe 6, which discharges the dried material pushed out by the rotating drum 1.
[0032] Please see Figure 4 An insert 7 is provided inside the cylinder cover 5. Please refer to [link / reference]. Figure 5The insert 7 is located below the axis of the roller 1. To further explain, there are multiple second cooling pipes 12 inside the roller 1. Unlike embodiment 1, in this embodiment, the second cooling pipes 12 are arranged in the insert 7 around the axis of the roller 1. Of course, the second cooling pipes 12 are all located below the axis of the roller 1. Compared with embodiment 1, in this embodiment, all the second cooling pipes 12 maintain the same distance from the inner wall of the roller 1.
[0033] In this embodiment, both ports of the second cooling pipe 12 are located within the insert 7. Please refer to [link / reference]. Figure 1 The insert 7 is equipped with a first valve 8 and a second valve 9. The first valve 8 is connected to the inlet of all the first cooling pipes 11, and the second valve 9 is connected to the outlet of all the first cooling pipes 11. In this way, nitrogen gas is introduced into the second cooling pipe 12 and connected to the horizontal dryer drum 1, so that the drying material entering the drum 1 can fully contact the second cooling pipe 12 during the rotation of the drum 1, thereby achieving the effect of cooling and reducing temperature.
[0034] Please see Figure 3 and Figure 5 Example 1 focuses on the cooling operation of a large amount of dried material entering the drum 1. Specifically, because the first cooling pipe 11 is arranged around the axis of the insert 7 in the insert 7, the first cooling pipe 11 is positioned relatively high, which can take care of the dried material at a higher position. Example 2 focuses on the cooling operation of a small amount of dried material entering the drum 1. Specifically, the second cooling pipe 12 is arranged around the axis of the drum 1 in the insert 7. All the second cooling pipes 12 maintain the same distance from the inner wall of the drum 1. When the height of the dried material inside the drum 1 is limited, all the second cooling pipes 12 can enter the dried material, resulting in a better cooling effect.
[0035] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0036] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
