Description

Technical Field

[0001] This utility model relates to the field of pyrometallurgical technology, and in particular to a surface cooling heat dissipation device. Background Technology

[0002] Pyrometallurgical processes utilize high temperatures (usually in a molten state) to separate metals from gangue and impurities in ores through chemical reactions such as oxidation, reduction, smelting, and blowing, ultimately obtaining crude metals or metal compounds.

[0003] High-temperature flue gas is produced during pyrometallurgical processes. This high-temperature flue gas is transported through pipelines to designated locations for treatment. However, due to the high temperature, the existing pipelines have limited heat dissipation capacity. If the temperature is not reduced in time, prolonged transport can lead to damage to dust collectors, filter bags, and pipelines. Therefore, it is extremely important to reduce the temperature of the flue gas in the pipeline during the transport process. Utility Model Content

[0004] The purpose of this utility model is to provide a surface cooling heat dissipation device that can improve the heat dissipation capacity of the pipeline, thereby reducing the temperature of the flue gas inside the pipeline.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A first air blowing pipe is movably sleeved on the conveying pipe, and a plurality of first air outlet holes are opened on the inner side wall of the first air blowing pipe.

[0008] A second air blowing pipe is provided at the top of the conveying pipe, and a third air blowing pipe is provided at the bottom. Several second air outlet holes are opened vertically downward on the second air blowing pipe, and several third air outlet holes are opened vertically downward on the third air blowing pipe.

[0009] The first air outlet hole is arranged correspondingly to the heat sink, and the second and third air outlet holes are both located between the heat sinks;

[0010] The first air blowing duct is provided with a plurality of first conveying connection pipes, the second air blowing duct is provided with a plurality of second conveying connection pipes, and the third air blowing duct is provided with a plurality of third conveying connection pipes, and the first, second, and third conveying connection pipes are all connected to external cold air conveying hoses.

[0011] As an improvement, the first air blowing pipe, the second air blowing pipe, and the third air blowing pipe are all annular conveying pipes.

[0012] As an improvement, a first conveying device is provided on the left side of the conveying pipe, and a second conveying device is provided on its right side.

[0013] As an improvement: the first conveying device includes a first portal frame, which is fixed to the left side of the conveying pipe. A first lead screw drive motor is vertically downward at the top of the first portal frame. The slider of the first lead screw drive motor is slidably locked inside the first portal frame. The first air blowing pipe is connected to the slider of the first lead screw drive motor through a first connecting rod.

[0014] As an improvement: the second conveying device includes a second portal frame, which is fixed to the right side of the conveying pipe. A second lead screw drive motor is vertically downward at the top of the second portal frame. The slider of the second lead screw drive motor is slidably locked inside the second portal frame. The first air blowing pipe is connected to the slider of the second lead screw drive motor through a second connecting rod.

[0015] As an improvement, connecting flanges are fixed at both ends of the conveying pipeline.

[0016] In summary, this utility model has the following beneficial effects:

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] Please refer to Figures 1-2 A surface cooling heat dissipation device includes a conveying pipe 1, on which a plurality of heat dissipation fins 2 are evenly distributed;

[0024] A first air-blowing pipe 3 is movably sleeved on the conveying pipe 1, and a number of first air outlet holes 4 are opened on the inner side wall of the first air-blowing pipe 3.

[0025] A second air-blowing pipe 5 is provided at the top of the conveying pipe 1, and a third air-blowing pipe 6 is provided at the bottom of the pipe. Several second air outlet holes 7 are opened vertically downward on the second air-blowing pipe 5, and several third air outlet holes 8 are opened vertically downward on the third air-blowing pipe 6.

[0026] The first air outlet 4 is positioned corresponding to the heat sink 2, and the second air outlet 7 and the third air outlet 8 are both located between the heat sink 2.

[0027] A plurality of first conveying connecting pipes 9 are provided on the first air blowing duct 3, a plurality of second conveying connecting pipes 10 are provided on the second air blowing duct 5, and a plurality of third conveying connecting pipes 11 are provided on the third air blowing duct 6. The first conveying connecting pipes 9, the second conveying connecting pipes 10, and the third conveying connecting pipes 11 are all connected to external cold air conveying hoses.

[0028] In this embodiment, the external cold air delivery hose can be connected to a fan, which can blow natural wind into the external cold air delivery hose, thereby applying the natural wind to the heat sink 2.

[0029] Furthermore, the second air outlet 7 and the third air outlet 8 are both vertically downward, which can allow natural air to act between each heat sink 2, thereby reducing the temperature of the heat sink 2. The first air outlet 4 is set in correspondence with the heat sink 2, which can allow natural air to act directly on the surface of the heat sink 2, thereby reducing the temperature of the heat sink 2.

[0030] By adding heat sinks 2 to the surface of the pipe, the heat dissipation capacity of the pipe can be improved. At the same time, after the heat sinks 2 dissipate heat, the heat on the heat sinks 2 can be blown away in time through the air blowing pipe. The above operation improves the heat dissipation capacity of the pipe, thereby reducing the temperature of the flue gas inside the pipe and protecting the relevant equipment.

[0031] In this embodiment, the first air blowing pipe 3, the second air blowing pipe 5, and the third air blowing pipe 6 are all annular conveying pipes 1.

[0032] A first conveying device is provided on the left side of the conveying pipe 1, and a second conveying device is provided on its right side. The first conveying device includes a first portal frame 12, which is fixed to the left side of the conveying pipe 1. A first lead screw drive motor 14 is vertically downward mounted on the top of the first portal frame 12, and the slider of the first lead screw drive motor 14 is slidably engaged within the first portal frame 12. The first air blowing pipe 3 is connected to the slider of the first lead screw drive motor 14 via a first connecting rod 16. The second conveying device includes a second portal frame 13, which is fixed to the right side of the conveying pipe 1. A second lead screw drive motor 15 is vertically downward mounted on the top of the second portal frame 13, and the slider of the second lead screw drive motor 15 is slidably engaged within the second portal frame 13. The first air blowing pipe 3 is connected to the slider of the second lead screw drive motor 15 via a second connecting rod 17.

[0033] In this embodiment, the position of the first air blowing pipe 3 can be adjusted by the first lead screw drive motor 14 and the second lead screw drive motor 15, so as to blow external cooling air onto the heat sink 2 and reduce the temperature of the heat sink 2.

[0034] Both ends of the conveying pipeline 1 are fixed with connecting flanges 18. In this embodiment, the connecting flanges 18 are used to connect other pipelines.

[0035] Working principle: When flue gas enters the conveying pipe 1, its heat is conducted to the heat sink 2. At the same time, the first lead screw drive motor 14 and the second lead screw drive motor 15 are started, driving the first air blowing pipe 3 to move up and down in the conveying pipe 1, so that natural air is applied to the surface of the heat sink 2, thereby reducing the temperature of the heat sink 2. At the same time, natural air can also be applied to each heat sink 2 through the second air blowing pipe 5 and the second air outlet hole 7 and the third air outlet hole 8 on the third air blowing pipe 6, thereby reducing the temperature of the heat sink 2 again. Through the above operation, the temperature of the heat sink 2 is rapidly reduced, thereby achieving a rapid reduction in the temperature of the flue gas in the pipe.
