Description

Technical Field

[0001] This utility model relates to the field of powder spheroidization technology, and more specifically, to a tube-type heat dissipation and rapid cooling device. Background Technology

[0002] Powder spheroidization is a technology that transforms powdered materials into spherical particles. This technology is widely used in powder metallurgy, ceramics, chemicals, and pharmaceuticals. Spheroidization can improve the material and processing properties of powdered materials, thereby increasing product quality and reducing production costs.

[0003] In the processing of powder materials, the particle shape of the powder has a significant impact on its performance. Powder spheroidization technology can transform powder materials into spherical particles, giving them better flowability and packaging properties, and improving product uniformity and stability. Traditional powders are typically irregularly shaped, have a large surface area, and poor flowability, which is detrimental to subsequent processing operations.

[0004] Existing powder spheroidization methods are as follows:

[0005] 1. Tumbler Spheroidizing Method: The powder is mixed with a spheroidizing agent and placed in a rotating drum. The tumbling motion gradually forms the particles into spheres. This method is simple and suitable for applications such as catalysts and chemical raw materials where moderate sphericity is required.

[0006] 2. High-speed airflow impact method: This method utilizes a high-speed airflow to cause powder to collide and rub against a hammerhead, achieving a four-stage sphericalization process: bending, sphericalization, adsorption, and compaction. It is commonly used in the processing of lithium-ion battery anode materials from natural and artificial graphite, improving tap density and electrochemical performance.

[0007] 3. Vacuum Induction Gas Atomization (VIGA): Suitable for metal powders such as high-temperature alloys and stainless steel. It uses inert gas to break up molten metal flow and form powder with high sphericity and narrow particle size distribution.

[0008] 4. Plasma atomization (PA): Suitable for active metals (such as titanium and zirconium), it uses plasma to impact and melt metal wires to form spherical particles, and is widely used in 3D printing and spraying.

[0009] 5. Flame spheroidization method: In a high-temperature flame of 1600-2000℃, the edges of angular powders (such as quartz) melt, and the surface tension causes them to shrink into a spherical shape. For example, the oxygen-acetylene flame method is used to process silicon micropowder.

[0010] 6. Plasma melting method: Powder is melted by an electric arc plasma high-temperature field, and the droplets are cooled to form spherical particles.

[0011] In summary, among the powder spheroidization technologies, except for the first two which use friction treatment, the others all involve melting the material to form droplets, which are then cooled to form spherical shapes. Rapidly cooling and solidifying the droplets before they collide with the processing chamber and equipment pipes, causing shape changes, helps improve spheroidization efficiency. Therefore, a tubular heat dissipation and rapid cooling device is urgently needed to solve this problem.

[0012] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0033] According to an embodiment of the present invention, a tube-type heat dissipation and rapid cooling device is provided.

[0034] Please refer to the instruction manual appendix. Figure 1-5 According to an embodiment of the present invention, a tube-type heat dissipation and rapid cooling device includes an upper housing 1, a lower housing 2 fixedly connected to the bottom end of the upper housing 1, a radiator 6 slidably installed on the inner side of the upper housing 1, an air inlet 4 fixedly connected to the right side of the top end of the upper housing 1, an exhaust port 5 fixedly connected to the left side of the top end of the upper housing 1, an upper discharge valve 7 fixedly installed at the bottom end of the lower housing 2, and a lower discharge valve 8 fixedly installed at the bottom end of the upper discharge valve 7.

[0035] Hot gas containing molten powder first enters the quenching device through the air inlet 4, and absorbs heat through the radiator 6 to cool down quickly. The lower chamber 2 at the bottom of the chamber is a slope, which can concentrate the condensed spherical powder at the discharge port. The upper discharge valve 7 and the lower discharge valve 8 are opened and closed alternately to achieve unloading without stopping the machine. At the same time, a partition plate is provided in the middle of the chamber, which makes the airflow have to flow out through the bottom of the chamber, thereby increasing the residence time of hot gas in the device and improving the cooling efficiency. Finally, the exhaust gas is discharged from the device through the exhaust port 5.

[0036] In one embodiment, please refer to the appendix to the specification. Figure 1-5 As a further embodiment of this utility model, a bracket 3 is fixedly installed on the outer side of the lower housing 2.

[0037] The height of the bracket can be selected according to the actual use environment, and the bracket also provides overall support for the device.

[0038] In one embodiment, please refer to the appendix to the specification. Figure 1-5 As a further embodiment of this utility model, the radiator 6 is provided with 4 sets, and the radiator 6 is fixedly connected to the upper housing 1 by bolts.

[0039] The combined action of multiple radiators can improve the heat dissipation efficiency of hot air containing molten powder, and the bolts also make it easy to disassemble and install the radiator 6.

[0040] In one embodiment, please refer to the appendix to the specification. Figure 1-5As a further embodiment of this utility model, the radiator 6 includes a frame plate 61, with tubes 62 fixedly installed on the inner side of the frame plate 61, and fins 63 fixedly connected to the outer side of the tubes 62.

[0041] Liquid nitrogen or other refrigerants can be introduced into the tubes, and the fins increase the contact area to absorb heat from the hot gas containing molten powder, achieving rapid cooling and condensation.

[0042] In one embodiment, please refer to the appendix to the specification. Figure 1-5 As a further embodiment of this utility model, a partition is provided in the center of the upper box 1.

[0043] This causes the hot air to flow downwards and then bend back in a U-shape to the exhaust port, increasing the contact time and area between the pressurized gas and the radiator, thus achieving good heat dissipation.

[0044] In one embodiment, please refer to the appendix to the specification. Figure 1-5 As a further embodiment of this utility model, both the air inlet 4 and the exhaust outlet 5 are connected to the upper housing 1.

[0045] This allows the hot air to circulate.

[0046] In one embodiment, please refer to the appendix to the specification. Figure 1-5 As a further embodiment of this utility model, the lower housing 2 is arranged in an inverted cone shape.

[0047] This causes the powder to concentrate at the discharge port.

[0048] In operation, hot gas containing molten powder first enters the quenching device through the inlet, where it absorbs heat and cools rapidly through the radiator. The bottom of the chamber is sloped, which helps to concentrate the condensed spherical powder at the discharge port. Continuous unloading is achieved by alternately opening and closing the upper and lower discharge valves. Simultaneously, a partition plate in the middle of the chamber causes the airflow to flow downwards and then bend back in a U-shape to the exhaust port, thereby increasing the residence time of the hot gas in the device and improving cooling efficiency. Finally, the exhaust gas is discharged from the device through the exhaust port.

[0049] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall fall within the protection scope of the present utility model.
