[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0028] like Figs. 1-5 As shown, this embodiment proposes a rapid cooling device for high-temperature concentrated sulfuric acid processing, including a base 1, a heat exchanger 21 fixedly connected to the top wall of the base 1, and a circulation pipe 22 fixedly connected to the outer wall of the heat exchanger 21. Cooled air enters the circulation pipe 22 from the air outlet pipe 10 and returns to the heat exchanger 21 for reuse. The device also includes:

[0029] The vibrating feeding assembly includes telescopic rods 2 uniformly and fixedly connected to the top wall of the base 1. A mounting plate 4 is fixedly connected to the top wall of the telescopic rods 2, and a support plate 5 is fixedly connected to the top wall of the mounting plate 4. A strong spring 3 is sleeved on the outer wall of the telescopic rods 2 and is fixedly connected to the mounting plate 4. The end of the strong spring 3 away from the mounting plate 4 is fixedly connected to the base 1. Symmetrically distributed rotating frames 14 are fixedly connected to the top wall of the support plate 5. Rotating rods 16 are rotatably connected to the outer wall of the rotating frames 14. A drive motor 15 is fixedly connected to the outer wall of the left rotating frame 14. The output end is fixedly connected to the rotating rod 16. Symmetrically distributed eccentric wheels 17 are fixedly connected to the outer wall of the rotating rod 16. When the drive motor 15 starts, it drives the rotating rod 16 to rotate. The eccentric wheels 17 on the rotating rod 16 rotate accordingly. Due to the eccentric structure of the eccentric wheel 17, it will generate a periodic impact force on the support plate 5 during the rotation process. This causes the support plate 5 to vibrate under the cooperation of the telescopic rod 2 and the strong spring 3. The support sleeve 6 on the support plate 5 and related components will also vibrate accordingly. Since the conveying pipe 8 is installed at an angle, the material in the conveying pipe 8 is conveyed during the vibration of the conveying pipe 8.

[0030] Support sleeve 6 is fixedly connected to the top wall of support plate 5;

[0031] The cooling assembly is located on the top wall of the base 1.

[0032] like Fig. 5As shown, in a preferred embodiment, based on the above method, the cooling assembly further includes a fan 18 fixedly connected to the top wall of the base 1. The air inlet of the fan 18 is fixedly connected to an air inlet pipe 19, and the air outlet of the fan 18 is fixedly connected to an air outlet pipe 20. The end of the air inlet pipe 19 away from the fan 18 is fixedly connected to the heat exchanger 21. When the fan 18 is started, cold air is drawn from the heat exchanger 21 through the air inlet pipe 19. After being pressurized by the fan 18, the air is delivered to the air inlet pipe 11 through the air outlet pipe 20.

[0033] like Figs. 1-2 As shown, in a preferred embodiment, based on the above method, a cooling sleeve 7 is further fixedly connected to the outer wall of the top wall of the support sleeve 6. An air inlet pipe 11 is fixedly connected to the outer wall of the cooling sleeve 7, and the air inlet pipe 11 is fixedly connected to the air outlet pipe 20. An air outlet pipe 10 is also fixedly connected to the outer wall of the cooling sleeve 7, and the air outlet pipe 10 is fixedly connected to the circulation pipe 22. Cold air is delivered to the cooling sleeve 7 through the air inlet pipe 11. Its heat dissipation plate 13 conducts heat from the sulfuric acid in contact with the conveying pipe 8 and contacts the cold air, so that the cold air exchanges heat with the high-temperature concentrated sulfuric acid in the conveying pipe 8 in the cooling sleeve 7, and takes away the heat of the concentrated sulfuric acid.

[0034] like Figs. 1-2 As shown, in a preferred embodiment, based on the above method, the top wall of the support sleeve 6 is further fixedly connected to a conveying pipe 8, and the conveying pipe 8 is fixedly connected to the cooling sleeve 7. The outer wall of the conveying pipe 8 is fixedly connected to a feed pipe 9, and the outer wall of the conveying pipe 8 is also fixedly connected to a discharge pipe 12. High-temperature concentrated sulfuric acid enters the conveying pipe 8 through the feed pipe 9, and is discharged through the discharge pipe 12 after the concentrated sulfuric acid is cooled.

[0035] like Fig. 3 As shown, in a preferred embodiment, based on the above method, a uniformly distributed heat dissipation plate 13 is fixedly connected to the outer wall of the conveying pipe 8, and the heat of concentrated sulfuric acid is quickly dissipated through the heat dissipation plate 13.

[0036] Specifically, the quick cooling device for high-temperature concentrated sulfuric acid processing is used as follows: the driving motor 15 is started to drive the rotating rod 16 to rotate, and the eccentric wheel 17 on the rotating rod 16 rotates, and the eccentric structure of the eccentric wheel 17 generates a periodic impact force on the supporting plate 5 during rotation, so that the supporting plate 5 vibrates under the cooperation of the telescopic rod 2 and the strong spring 3, and the supporting sleeve 6 and related parts on the supporting plate 5 also vibrate, and since the conveying pipe 8 is installed at an angle, the conveying pipe 8 is vibrated to realize the conveying of the material in the conveying pipe 8; the fan 18 is started to draw cold air from the heat exchanger 21 through the air inlet pipe 19, and after being pressurized by the fan 18, the air is conveyed to the air inlet connecting pipe 11 through the air outlet pipe 20, and then enters the cooling sleeve 7, and the heat sink 13 of the cooling sleeve 7 conducts the heat of the concentrated sulfuric acid on the conveying pipe 8 and contacts the cold air to realize heat exchange between the cold air in the cooling sleeve 7 and the high-temperature concentrated sulfuric acid in the conveying pipe 8, so as to take away the heat of the concentrated sulfuric acid, and the cooled air enters the circulating pipe 22 from the air outlet connecting pipe 10 and returns to the heat exchanger 21 for recycling, and the concentrated sulfuric acid enters the conveying pipe 8 from the feeding pipe 9, and is discharged from the discharging pipe 12 after being cooled under the action of the vibrating feeding assembly.
