DETAILED DESCRIPTION

[0029] The following will refer to the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] In order to further understand the content of the utility model, the utility model is described in detail with reference to the accompanying drawings.

[0031] Reference Figure 1 , Figure 2 and Figure 3 The utility model discloses an airflow multi-stage cooling device for carbon black production, comprising a cooling tube 1. When the three cooling tubes 1 are installed, an air inlet tube (not marked in the figure) is arranged on the left side of the first cooling tube 1, and an exhaust tube (not marked in the figure) is arranged on the right side of the last cooling tube 1. The two sides of the middle connected cooling tube 1 are respectively provided with an airflow inlet tube 12 and an airflow outlet tube 8, which are convenient for splicing. The three cooling tubes 1 are all provided with spiral heat dissipation tubes 2, which are convenient for cooling the airflow in the cooling tube 1. The outer sides of the three cooling tubes 1 are all provided with heat dissipation components. The right sides of the three cooling tubes 1 are penetrated and fixedly connected with an airflow outlet tube 8, which is convenient for airflow discharge. The outer side of the airflow outlet tube 8 is provided with an installation groove 9, and the installation groove 9 is fixedly connected with a uniformly distributed first spring 10, which can drive the telescopic sleeve 11 through the compression and expansion of the first spring 10. It is telescopic in the installation groove 9, and the other end of the first spring 10 is fixedly connected to a telescopic sleeve 11. The left side of the cooling pipe 1 passes through and is fixedly connected to an air flow inlet pipe 12, and the left side of the air flow inlet pipe 12 is fixedly connected to a sealing sleeve 13 to improve the sealing effect. The front and rear ends of the air flow inlet pipe 12 are fixedly connected to the outside with connecting blocks 14 to play a connecting role. The outside of the connecting block 14 is fixedly connected to a limiting plug block 15 in a hemispherical shape. The front and rear ends of the air flow outlet pipe 8 are fixedly connected to a connecting frame 16, and a sliding groove 17 is provided on the outside of the connecting frame 16 to limit the limiting clamping block 18. Two limiting clamping blocks 18 are slidably connected in the sliding groove 17. Support plates 19 are fixedly connected on both sides of the connecting frame 16 to support the pull rod 20. The two support plates 19 are penetrated and slidably connected with the pull rod 20.

[0032] Reference Figure 1The heat dissipation component includes a water tank 7, which is arranged on the front side of the cooling pipe 1. A connecting pipe 6 is passed through and fixedly connected to the left side of the water tank 7. A water pump 5 is fixedly connected to the other end of the connecting pipe 6. The other end of the water pump 5 is fixedly connected to the water inlet pipe 4. A water outlet pipe 3 is passed through and fixedly connected to the rear side of the water tank 7. The water outlet pipe 3 passes through the cooling pipe 1 and is fixedly connected to the right end of the spiral heat dissipation pipe 2. The cooling water can be circulated in the spiral heat dissipation pipe 2 through the heat dissipation component, thereby cooling down the high-temperature airflow in the cooling pipe 1.

[0033] Reference Figure 1 , Figure 2 and Figure 3 The telescopic sleeve 11 is arranged in the installation groove 9, and the outside of the telescopic sleeve 11 is slidably connected to the inner wall of the installation groove 9, so that the telescopic sleeve 11 can be telescoped in the installation groove 9. The opposite sides of the two pull rods 20 are fixedly connected to the limit clamp 18, and the opposite sides of the two pull rods 20 are fixedly connected to the limit block 21, so that the limit clamp 18 can be driven to move by the pull rod 20. The limit block 21 is arranged on the outside of the support plate 19, and the outer sleeve of the pull rod 20 is provided with a second spring 22, which is arranged between the limit clamp 18 and the support plate 19. The second spring 22 can be reset to drive the two limit clamps 18 to move relative to each other. The bottoms of the three cooling pipes 1 are fixedly connected to the support frame 23, which can fix the cooling pipe 1. The water inlet pipe 4 passes through the cooling pipe 1 and is fixedly connected to the left end of the spiral heat dissipation pipe 2.

[0034] Working principle: During operation, after the carbon black is produced, the temperature of the airflow coming out is relatively high, and it needs to be cooled. The high-temperature airflow enters the cooling tube 1 from the air inlet pipe (not marked in the figure) of the first cooling tube 1, and is discharged from the air outlet pipe (not marked in the figure) of the last cooling tube 1 to cool the high-temperature airflow. During cooling, the water pump 5 draws out the cooling water in the water tank 7 through the connecting pipe 6, and enters the spiral heat dissipation tube 2 in the cooling tube 1 through the water inlet pipe 4. The airflow is cooled by the spiral heat dissipation tube 2 in the cooling tube 1, and the cooling water in the spiral heat dissipation tube 2 flows back to the water tank 7 through the water outlet pipe 3 for circulation. When multiple cooling tubes 1 need to be connected and installed, align the airflow outlet pipe 8 of one cooling tube 1 with the airflow inlet pipe 12 of another cooling tube 1, so that the airflow inlet pipe 12 is aligned with the airflow outlet pipe 8 of the cooling tube 1. The limiting plug 15 on the side is inserted between the two limiting clamps 18 on both sides of the air outlet pipe 8. At this time, the two limiting clamps 18 are squeezed and slide to both sides in the slide groove 17. The two limiting clamps 18 squeeze the second springs 22 to both sides. After the limiting plug 15 enters the two limiting clamps 18, the second spring 22 is reset, driving the two limiting clamps 18 to move relative to each other again to limit the limiting plug 15. At the same time, the sealing sleeve 13 squeezes the telescopic sleeve 11. The first spring 10 is compressed and expanded and expanded, which can drive the telescopic sleeve 11 to expand and contract in the installation groove 9, so that the sealing sleeve 13 and the telescopic sleeve 11 are more closely fitted, thereby improving the sealing during connection. When disassembly is required, the limiting block 21 is pulled by hand to drive the pull rod 20 and the limiting clamp 18 to move, so as to release the restriction on the limiting plug 15 and facilitate disassembly.
