The atomized powder needs to be collected by a collection device. However, after high-temperature treatment, the powder has a high residual temperature, and the existing collection devices have low cooling efficiency, requiring at least 4 hours to cool to a safe temperature, which affects the packaging efficiency. Therefore, this is a technical problem that urgently needs to be solved. Utility Model Content

[0020] As shown in the attached figure: A rapid water-cooled high-temperature cooling material package includes a hopper 1 and an inner water jacket 2. The inner water jacket 2 is disposed in the inner layer of the hopper 1. The hopper 1 is provided with a water-cooling coil 3, which has a spiral structure and through which cooling water flows. Preferably, the hopper 1 is cone-shaped, with an inlet 5 at the bottom communicating with the inner water jacket 2, and an outlet 13 at the top communicating with the inner water jacket 2.

[0021] The advantage of this solution is that by setting up a water-cooled coil 3 inside the hopper 1, the internal cooling efficiency during powder accumulation is improved. At the same time, combined with the inner cylinder water jacket 2, both inside and outside cooling are carried out simultaneously, thereby achieving the purpose of rapid cooling and reducing the powder cooling time.

[0022] In this embodiment, the water-cooled coil 3 is in a spiral shape with a larger top and a smaller bottom, and the water flows from bottom to top to improve heat exchange. The water-cooled coil 3 is made of a high thermal conductivity metal material, such as copper or copper alloy, to improve the heat exchange efficiency of the water-cooled coil 3.

[0023] In another embodiment, at least one water-cooling coil 3 is arranged in a disc shape and multiple layers are arranged vertically; preferably, two or three water-cooling coils 3 are arranged, and the water-cooling coils 3 are connected by coils and support each other to avoid the water-cooling coils 3 from being too heavy and deforming. At the same time, a bracket 4 can also be provided to support the water-cooling coils 3.

[0024] In this embodiment, the upper end of the water-cooled coil 3 is provided with an inlet pipe 14 and an outlet pipe 10. The inlet pipe 14 is connected to a cold water source, and the outlet pipe 10 is connected to a radiator. After heat dissipation, the water can be recycled, reducing water waste. Preferably, the inlet pipe 14 and the outlet pipe 10 are respectively installed at the upper end of the silo 1 via flanges for easy inspection and maintenance. Alternatively, the inlet pipe 14 and the outlet pipe 10 are respectively fixed to the upper end of the silo 1 by through-welding.

[0025] In this embodiment, the silo 1 has a feed inlet 12 at the top, and a first valve 11 on the feed inlet 12. The silo 1 has a discharge outlet 8 at the bottom, and a second valve 7 on the discharge outlet 8. The silo 1 has a support 4 at the bottom, and rollers 6 at the bottom of the support 4. The silo 1 has lifting lugs 9.

[0026] This invention uses a water-cooling coil 3 installed inside the silo 1 to rapidly cool the interior of the accumulated powder. Combined with the water jacket 2 of the inner cylinder of the silo 1, it achieves the purpose of cooling the powder inside and outside the silo 1 simultaneously, thus realizing rapid cooling and reducing the cooling time of the powder.
