Since the internal space of the ladle cavity 221 is very small, after the process liquid is scooped out, the tin liquid leaks out to the bottom due to the internal attraction of the process liquid, and flows rapidly, as shown in fig. 5, in some examples, one end of the upper surface of the ladle 22 protrudes upwards to form a protrusion 222 with an inner ring wall, the inner ring wall of the protrusion 222 encloses to form the ladle cavity 221, the top end surface of the protrusion 222 is provided with a flow guiding surface 222a which gradually inclines from top to bottom towards the axis far away from the ladle cavity 221, and the flow guiding surface 222a is arranged on the outer side of the ladle cavity 221 in a surrounding manner; the arrangement of the flow guide surface 222a can gradually discharge the process liquid at the peripheral edge of the spoon cavity 221 in the process that the liquid scooping spoon 22 leaves the process liquid in the inner cavity 11, so that the process liquid is prevented from being retained at the peripheral edge of the spoon cavity 221, a large amount of process liquid is prevented from being gathered at the peripheral edge of the top of the spoon cavity 221 after the liquid scooping spoon 22 scoops the process liquid, and the process liquid in the spoon cavity 221 is prevented from being rapidly flowed when the large amount of process liquid at the peripheral edge of the top of the spoon cavity 221 flows downwards.
In some examples, as shown in fig. 4, the device further comprises a liquid scraping mechanism 4, wherein the liquid scraping mechanism 4 is provided with a scraping plate 42 and a liquid scraping power assembly 41, and the liquid scraping power assembly 41 is used for driving the scraping plate 42 to reciprocate, so that the scraping plate 42 scrapes the liquid level of the process liquid in the inner cavity 11; the scooping mechanism 2 is further configured such that, after the scraper 42 scrapes the liquid surface, the scoop cavity 221 of the scooping scoop 22 takes out the process liquid from the inner cavity 11; scraping the oxide layer (such as tin slag) on the liquid surface of the process liquid at the moving path in the process of the process liquid by the scraper 42, and then scooping the process liquid after scraping impurities by the scraper 221, so as to improve the gold removing or tin coating effect;
The scraping power assembly 41 can be, but is not limited to, an electric push rod, a linear module, a cylinder or the like, taking the scraping power assembly 41 as an example, the cylinder body of the cylinder serving as the scraping power assembly 41 is fixedly arranged on the outer wall of the container 1, the piston rod of the cylinder is fixedly connected with the scraping plate 42, heat insulation pieces are connected between the cylinder body of the cylinder and the outer wall of the container 1 and between the piston rod of the cylinder and the scraping plate 42, and the purpose of heat insulation of the cylinder is achieved; in the case of scraping, the cylinder as the scraping power unit 41 may be, but is not limited to, a displacement with the scraper 42 in the left-right direction (Y-axis direction);
