[0018] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0019] like Figure 1-6As shown, this embodiment of a drying device for cleaned metal raw materials includes an outer box 1. A rotating cylinder 2 is located at the center of the inner cavity of the outer box 1, serving as a storage chamber for the cleaned raw materials. A drainage unit is formed on the outer periphery of the rotating cylinder 2, and the storage chamber is connected to the inner cavity of the outer box through the drainage unit. A horizontally arranged rotating shaft 4 passes through the center of the rotating cylinder 2, with both ends of the rotating shaft 4 mounted on and protruding from the outer box 1. The rotating shaft 4 has a horizontally arranged gas channel 4.2 at its center, and one end of the rotating shaft 4 is an air inlet 4.3. Multiple sets of exhaust holes are formed on the outer periphery of the rotating shaft 4, evenly distributed circumferentially along the center line of the rotating shaft 4. The air inlet 4.3, the exhaust holes, and the gas channel 4.2 are interconnected. A handle 5 is provided at the other end of the rotating shaft 4. Shaking the handle 5 drives the rotating shaft and the rotating drum to rotate. The cleaned raw materials in the storage cavity are swung around, so that the water swung out flows into the outer box through the drain hole group. The drying gas enters the gas channel through the air inlet, and then the drying gas in the gas channel is discharged through multiple sets of exhaust holes, so that the drying gas can fully blow the swung raw materials and thoroughly dry the raw materials.

[0020] The outer box 1 includes an upper box 1.1 and a lower box 1.2. The bottom of the upper box 1.1 has a mating groove, and the top of the lower box 1.2 has a mating protrusion. The mating groove and the mating protrusion match each other, so that the mating protrusion is located in the mating groove, and the upper box and the lower box are mated and connected, making it easy for the rotating cylinder to be placed in the outer box.

[0021] The rotating drum 2 is open at one end and closed at the other. The cleaned raw materials are placed into the storage cavity through the opening. A rotating drum cover 3 is mounted on the rotating shaft 4, covering the open end of the rotating drum 2. Four rotating drum cover protrusions 3.1 are symmetrically arranged on the outer periphery of the rotating drum cover 3. Four rotating drum grooves 2.2 are formed at the open end of the rotating drum 2. The rotating drum cover protrusions 3.1 and the rotating drum grooves 2.2 match, ensuring that the rotating drum cover 3 covers the open end of the rotating drum 2, thus sealing the storage cavity. When it is necessary to add or discharge materials, the rotating drum cover can be opened.

[0022] Each vent hole group includes several vent holes 4.1 evenly distributed along the length of the rotating shaft. The drainage unit includes multiple drainage hole groups, which are evenly distributed circumferentially along the center line of the rotating drum. Each drainage hole group includes several drainage holes 2.1 evenly distributed along the length of the rotating drum.

[0023] The outer box 1, rotating cylinder 2, and rotating shaft 4 mentioned above are all made of TFL material.

[0024] The aforementioned drying gas is nitrogen.

[0025] In use, the cleaned raw materials are placed inside the rotating drum, nitrogen is introduced into the air inlet, and the handle is manually turned while the nitrogen thoroughly purges the raw materials, ensuring that each piece is completely dry. This application has a simple and ingenious structure that enables the raw materials to dry more thoroughly, avoiding abnormal parameters or metal detachment after use due to incomplete drying of the cleaned metal raw materials.

[0026] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
