[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-7 This utility model provides a technical solution: a device for precise removal of impurities during the refining process of yellow phosphorus, including an outer shell 1, a shell cover 2, a feed pipe 3, a discharge pipe 4, a heating wire 5, a feeding pipe 6, a separation pipe 7, a motor 8, a rotating drum 9, a stirring rod 10, a lower scraper 11, a protrusion 12, a sieve plate 13, a connecting rod 14, a connecting block 15, an upper scraper 16, and a connecting ring 17.

[0030] The lower surface of the outer shell 1 has an inverted trapezoidal recess. The upper part of the outer shell 1 is connected to the shell cover 2 by bolts. The surface of the shell cover 2 is provided with a feed pipe 3. The bottom surface of the outer shell 1 is provided with a discharge pipe 4.

The interlayer of the outer shell 1 is provided with a heating wire 5. One side surface of the outer shell 1 is provided with a feeding pipe 6. The other side surface of the outer shell 1 is provided with a separation pipe 7. The feeding pipe 6 and the separation pipe 7 are respectively provided with valves. The outer shell 1 is provided with a stirring structure. The stirring structure achieves stirring of yellow phosphorus by rotating stirring rod 10. The stirring structure includes a motor 8. The motor 8 is fixedly installed in the inverted trapezoidal recess at the bottom of the outer shell 1. The output end of the motor 8 is connected to a rotating drum 9 through the lower surface of the outer shell 1. The rotating drum 9 is inserted into the interior of the outer shell 1. The outer surface of the rotating drum 9 is provided with a ring of stirring rod 10. The outer surface of the rotating drum 9 is fixedly installed with a lower scraper 11. The lower scraper 11 is inverted trapezoidal and fits against the inner surface of the outer shell 1.

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, connect the cover 2 to the outer shell 1, open the valve of the feed pipe 3, and pour the yellow phosphorus into the outer shell 1. After feeding, close the valve of the feed pipe 3, open the valve of the feeding pipe 6, and add the reactant into the outer shell 1. After feeding, close the valve of the feeding pipe 6, turn on the heating wire 5, and use the heating wire 5 to heat the yellow phosphorus. Start the motor 8, and the motor 8 drives the rotating drum 9 to rotate. The stirring rod 10 on the outer surface of the rotating drum 9 rotates accordingly to fully stir the yellow phosphorus and reactant. During the stirring process, the stirring rod 10 continuously turns the yellow phosphorus and reactant to make them evenly mixed, accelerate the chemical reaction, and promote the full reaction of impurities and reactants to generate substances that are easy to separate. When the rotating drum 9 rotates, the lower scraper 11 rotates synchronously close to the inner surface of the outer shell 1 to scrape off the yellow phosphorus and impurities attached to the inner wall of the outer shell 1 in time, preventing the accumulation of yellow phosphorus from affecting the operation of the device. After the reaction is completed, the refined yellow phosphorus is discharged from the separation pipe 7, and the impurities in the yellow phosphorus are discharged from the discharge pipe 4 below.

[0032] The upper end of the rotating drum 9 is provided with a protrusion 12, which has a cross-shaped structure. A filter structure is provided above the protrusion 12. The filter structure achieves preliminary filtration of yellow phosphorus through the sieve plate 13. The filter structure includes the sieve plate 13, which has a W-shaped cross-section. A connecting rod 14 is provided through the center of the sieve plate 13. The connecting rod 14 is rotatably connected to the surface of the sieve plate 13. The lower end of the connecting rod 14 is provided with a groove, which engages with the protrusion 12. The upper end of the connecting rod 14 is threadedly connected to a connecting block 15, which is cylindrical. An upper scraper 16 is fixedly installed on the outer surface of the connecting block 15. The upper scraper 16 is in contact with the inner surface of the sieve plate 13. The lower surface of the sieve plate 13 is in contact with the upper surface of the connecting ring 17, which is annular. The connecting ring 17 is fixedly installed on the inner wall of the outer shell 1. The connecting ring 17 and the sieve plate 13 are connected by bolts.

[0033] like Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, the rotating drum 9 is installed inside the outer casing 1. The rotating drum 9 is connected to the connecting ring 17 by bolts. At this time, the groove at the lower end of the connecting rod 14 at the center of the screen plate 13 is aligned with the cross-shaped protrusion 12 at the upper end of the rotating drum 9, so that the two are tightly engaged. The connecting block 15 is threadedly connected to the upper end of the connecting rod 14 to ensure that the upper scraper 16 is in contact with the inner surface of the screen plate 13. When the yellow phosphorus enters from the feed pipe 3, the yellow phosphorus falls downward onto the surface of the screen plate 13. Under the action of gravity, the yellow phosphorus flows downward through the screen holes, while the impurities are intercepted on the screen plate 13. When the motor 8 drives the rotating drum 9 to rotate, it will drive the protrusion 12 to rotate, which in turn causes the connecting rod 14 to rotate. The rotating connecting rod 14 drives the connecting block 15 to rotate, which in turn drives the upper scraper 16 to rotate. The upper scraper 16 exerts force on the inner surface of the screen plate 13, scraping off the residual impurities and preventing the impurities from clogging the screen holes.

[0034] Working principle: When using this device for precise impurity removal during the refining of yellow phosphorus, yellow phosphorus is poured into the outer shell 1 and falls onto the surface of the sieve plate 13 for filtration. The heating wire 5 and motor 8 are started, and the reactant is added into the outer shell 1. The motor 8 drives the rotating drum 9 to rotate. During the rotation of the rotating drum 9, the stirring rod 10, the lower scraper 11, and the protrusion 12 will rotate synchronously. The stirring rod 10 stirs and mixes the yellow phosphorus and the reactant, while the lower scraper 11 prevents accumulation from affecting the operation of the device. The protrusion 12 drives the connecting rod 14 and the connecting block 15 to rotate, which in turn drives the upper scraper 16 to rotate, preventing impurities from clogging the sieve plate 13. After the reaction is completed, the refined yellow phosphorus is discharged from the separation pipe 7, and the impurities in the yellow phosphorus are discharged from the discharge pipe 4 below, increasing the overall practicality.
