[0002] In the process of preparing metal nanopowders, the melting chamber is a crucial link. The existing melting chamber design still has some technical deficiencies, which affect the preparation efficiency and quality of metal nanopowders.

[0003] Traditional melting chambers usually lack effective cooling mechanisms, which makes it difficult to dissipate the heat generated during the melting process in a timely manner, thus affecting the quality of the product and the life of the equipment. At the same time, the setting of the observation port is often not user-friendly, which makes it inconvenient for operators to observe the melting process in real time, making it difficult to adjust the process parameters in time to ensure product quality. In addition, the existing melting chambers also have certain limitations in structural design, such as the connection method between the door cover and the cylinder, the location of the air inlet and the water outlet, etc., which may affect the performance and ease of operation of the melting chamber. Utility Model Content

[0014] In the smelting chamber for preparing metal nanopowder, efficient cooling mechanisms are set inside and outside the smelting chamber, including a barrel water inlet, a barrel water outlet, an observation water inlet, etc. These designs ensure that the heat generated during the smelting process can be dissipated in time, effectively preventing the equipment from overheating, not only protecting the equipment, but also improving the quality and stability of the product. The design of the observation port fully considers the needs of humanization. Its inclined setting enables the operator to observe the smelting process more intuitively, which is convenient for real-time adjustment of process parameters, thereby ensuring the stability and consistency of product quality. At the same time, the setting of the observation air port further prevents the observation port from being blurred due to high temperature, ensuring the clarity of observation. The structural design of the smelting chamber also fully considers practicality and convenience. The door cover is flexibly connected to the outer barrel of the smelting chamber through the door cover hinge seat, which is convenient for opening and closing. The setting of the door cover water inlet and the door cover water outlet further enhances the cooling effect of the door cover and prolongs its service life.
