[0031] The servo motor 22 is connected to the transmission rod 2 through a gear transmission;

[0032] The outer wall of the impeller 33 is in sliding engagement with the inner wall of the rectangular tube 3;

[0033] It should be noted that: when in use, a copper sulfate solution with a pH value of 0.5 to 4.8 is introduced into the cylinder 1 from the liquid inlet pipe 131. When pouring, the liquid level is controlled to be below the powder sprinkling hole 202. Then, the reduced iron powder is placed in the hopper 1 23 and the hopper 2 31. Then, the servo motor 22 is started. The servo motor 22 drives the transmission rod 2 to rotate through the gear transmission. When the transmission rod 2 rotates, the iron powder in the placement chamber 201 is evenly sprinkled from the powder sprinkling hole 202 to the center of the cylinder 1.

[0034] In the embodiments of the present invention, please refer to Figure 1 and Figure 4, a transfer rod 4 is fixedly installed at the bottom end of the transmission rod 2, a connecting plate 41 is fixedly installed on the outer wall of the transfer rod 4, a side scraper 42 is installed on the upper part of the end of the connecting plate 41 away from the transfer rod 4, the outer wall of the side scraper 42 is slidably matched with the inner wall of the cylinder 1, and a bottom scraper 43 is installed on the lower part of the end of the connecting plate 41 away from the transfer rod 4, and the outer wall of the bottom scraper 43 is slidably matched with the inner wall of the bottom tray 11;

[0035] It should be noted that when the transmission rod 2 rotates, the transfer rod 4 is driven to rotate synchronously, thereby driving the side scrapers 42 and the bottom scraper 43 to rotate, continuously scraping the inner wall of the cylinder 1 and the bottom tray 11 to prevent the copper-clad iron powder from adhering to the inner wall of the cylinder 1;

[0036] In this embodiment, a spiral conveying rod 44 is fixedly installed at the bottom end of the adapter rod 4, so that the copper-coated iron powder precipitated after the reaction and the unreacted iron powder are continuously rotated and conveyed upward, thereby performing repeated stirring, so that the iron powder is fully coated with copper, which is beneficial to improving the processing quality.

[0041] The working principle of the dissolving kettle for producing copper-clad iron powder provided by the utility model is as follows:

[0042] During use, a copper sulfate solution with a pH value of 0.5 to 4.8 is introduced into the cylinder 1 from the liquid inlet pipe 131. When pouring, the liquid level is controlled to be below the powder sprinkling hole 202. Then, the reduced iron powder is placed in the hopper 1 23 and the hopper 2 31. Then, the servo motor 22 is started. The servo motor 22 drives the transmission rod 2 to rotate through the gear transmission. When the transmission rod 2 rotates, the iron powder in the placement chamber 201 is evenly sprinkled from the powder sprinkling hole 202 to the center of the cylinder 1. Then, the transmission rod 2 rotates through the connecting frame. 35 drives the driving bevel gear 36 to rotate, and the driving bevel gear 36 meshes with the driven bevel gear 34, thereby driving the transmission shaft 32 to rotate, thereby driving the impeller 33 to rotate synchronously, and the iron powder in the rectangular tube 3 is rotated and sprinkled from the impeller 33, thereby sprinkling the reduced iron powder around the cylinder 1, and the transmission rod 2 drives the stirring rod 21 to rotate synchronously, so that the iron powder is stirred after being sprinkled, thereby achieving stirring, so that the copper is completely coated on the surface of the iron powder particles, and the iron powder is dispersed step by step, so as to fully contact and react with the copper liquid;

[0043] Furthermore, when the transmission rod 2 rotates, it drives the adapter rod 4 to rotate synchronously, thereby driving the side scraper 42 and the bottom scraper 43 to rotate, continuously scraping the inner walls of the cylinder 1 and the bottom tray 11 to prevent the copper-clad iron powder from adhering to the inner wall of the cylinder 1. At the same time, when the side scraper 42 is scraping, the stirring rod 2 421 is synchronously driven to rotate, further stirring, making the stirring more uniform. A spiral conveying rod 44 is fixedly installed at the bottom end of the adapter rod 4, so that the copper-clad iron powder precipitated after the reaction and the unreacted iron powder are continuously rotated and conveyed upward, thereby performing repeated stirring, so that the iron powder is fully coated with copper, which is beneficial to improving the processing quality.
