[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solution in the embodiments of the present invention.

[0026] It should also be noted that the division of multiple embodiments in the present invention is only for the convenience of description and should not constitute a special limitation. The features in various embodiments can be combined and referenced to each other without contradiction.

[0027] like Figure 1 As shown, the embodiment of the utility model provides a device 10 for preparing high-purity antimony. Specifically, the device 10 for preparing high-purity antimony includes, for example: a hydrolysis device 100, a waste liquid collection box 200, a drying device 300 and a reduction device 400.

[0028] Specifically, Figure 1As shown, the top of the hydrolysis device 100 is provided with a plurality of feed ports, and the bottom of the hydrolysis device 100 is provided with a first waste liquid discharge port 140 and a hydrolyzate discharge port 150. The waste liquid collection box 200 is provided with a first waste liquid feed port 210 and a second waste liquid feed port 220, and the first waste liquid feed port 210 is connected to the first waste liquid discharge port 140. The drying device 300 is provided with a hydrolyzate feed port 340, a second waste liquid discharge port 360 and a dried product discharge port 350, and the hydrolyzate feed port 340 is connected to the hydrolyzate discharge port 150. The second waste liquid discharge port 360 is connected to the second waste liquid feed port 220. The reduction device 400 is provided with a dried product feed port 410, and the dried product feed port 410 is connected to the dried product discharge port 350.

[0029] Secondly, if Figure 1 As shown, the first waste liquid discharge port 140 is provided with a first filter element 110, and the second waste liquid discharge port 360 is provided with a second filter element 310. A first switch valve 120 is provided between the first waste liquid feed port 210 and the first waste liquid discharge port 140. A second switch valve 130 is provided between the hydrolyzate feed port 340 and the hydrolyzate discharge port 150. A third switch valve 320 is provided between the second waste liquid discharge port 360 and the second waste liquid feed port 220. A fourth switch valve 330 is provided between the dry material feed port 410 and the dry material discharge port 350. Among them, the first filter element 110 and the second filter element 310 are, for example, filter nets.

[0030] For example, when a hydrolysis reaction occurs in the hydrolysis device 100, waste liquid and precipitate are generated. By controlling the first switch valve 120 and the second switch valve 130, the waste liquid and precipitate can flow to the waste liquid collection box 200 and the drying device 300 respectively. The precipitate entering the drying device 300 will also carry a portion of the waste liquid. At this time, by controlling the third switch valve 320 and the fourth switch valve 330, the waste liquid and the dried precipitate are controlled to enter the waste liquid collection box 200 and the reduction device 400 respectively.

[0031] The embodiment of the utility model integrates the hydrolysis device 100, the waste liquid collection box 200, the drying device 300 and the reduction device 400 so that the hydrolysis-drying-reduction reaction can be completed in the same device, thereby reducing the entry of impurities, thereby ensuring the purity of the antimony product during the production process. Secondly, the embodiment integrates the equipment so that the equipment is simple and easy to operate, stable and reliable, has low manufacturing cost, low energy consumption, high safety, and can achieve continuous production.

[0032] Alternatively, if Figure 1 and Figure 2As shown, the hydrolysis device 100 is provided with a first temperature control component, for example. The first temperature control component is used to heat the hydrolysis device 100 and monitor the temperature inside the hydrolysis device 100. Specifically, the first temperature control component includes, for example, a first thermocouple 600 and a first heater 610. The first heater 610 is, for example, a resistance heater. The first heater 610 and the first thermocouple 600 are, for example, controlled by a main controller, which is, for example, a CPU.

[0033] like Figure 1 and Figure 2 As shown, for example, the first heater 610 is used to heat the hydrolysis device 100, and the first thermocouple 600 is used to monitor the temperature in the hydrolysis device 100. When the first thermocouple 600 detects that the temperature in the hydrolysis device 100 reaches the temperature required for the hydrolysis reaction, the corresponding information is fed back to the main controller, and the main controller controls the first heater 610 to stop heating according to the corresponding information. In this embodiment, by providing the first heater 610 and the first thermocouple 600, the temperature in the hydrolysis device 100 can be monitored in real time while the hydrolysis device 100 is heated, so as to accurately grasp whether the temperature in the hydrolysis device 100 meets the temperature required for the hydrolysis reaction, so as to better perform the hydrolysis reaction and improve the reaction efficiency of the hydrolysis reaction.

[0034] Secondly, if Figure 1 and Figure 2 As shown, a liquid spraying assembly 700 is provided on the hydrolysis device 100, and the liquid spraying assembly 700 is movably connected to the hydrolysis device 100. In this embodiment, the liquid spraying assembly 700 can be rotated relative to the hydrolysis device 100, so as to adjust the angle at which the liquid spraying assembly 700 sprays the waste liquid. The liquid spraying assembly 700 is used to clean the sediment in the hydrolysis device 100. Specifically, the liquid spraying assembly 700 includes, for example, two high-pressure nozzles and four low-pressure nozzles. The pressure of the high-pressure nozzle is, for example, 1 to 2.5 MPa, and the pressure of the low-pressure nozzle is, for example, 0.3 to 1 MPa. A stirrer 800 is provided on the hydrolysis device 100, and the stirrer 800 is used to stir the materials in the hydrolysis device 100 so that they react fully. Optionally, the stirring blades of the stirrer 800 are, for example, in a shape that basically fits the bottom of the hydrolysis device 100, so as to make the stirring more thorough.

[0035] like Figure 1 and Figure 2 As shown, in this embodiment, for example, antimony trichloride powder is used as a raw material, and the antimony trichloride powder is hydrolyzed with hydrochloric acid and concentrated ammonia water to produce a precipitate, and the precipitate is antimony trioxide. After the precipitate is dried, it is reduced with hydrogen to produce an antimony product. Optionally, the multiple feed ports of the hydrolysis device 100 include, for example, a solid feed port 160, a first liquid inlet 170, and a second liquid inlet 180.

[0036] Alternatively, if Figure 1 and Figure 2 As shown, a pH meter 500 is provided on the hydrolysis device 100, and the pH meter 500 is used to monitor the pH value in the hydrolysis device 100. For example, when antimony trichloride powder reacts with hydrochloric acid and concentrated ammonia water in the hydrolysis device 100, the pH value in the hydrolysis device 100 will change because hydrochloric acid and concentrated ammonia water are introduced into the hydrolysis device 100. In this embodiment, the pH value in the hydrolysis device 100 is monitored in real time by providing a pH meter. When the pH value in the hydrolysis device 100 meets the pH value required for the hydrolysis reaction, the introduction of hydrochloric acid and concentrated ammonia water is stopped; if the pH value in the hydrolysis device 100 does not meet the pH value required for the hydrolysis reaction, the pH value in the hydrolysis device 100 can be adjusted by introducing hydrochloric acid or concentrated ammonia water. In this embodiment, by providing a pH meter, the pH value in the hydrolysis device 100 can be controlled at a pH value suitable for the hydrolysis reaction, so that the antimony trichloride powder can be better hydrolyzed, thereby improving the efficiency of the hydrolysis reaction. Secondly, a visual mirror 190 is provided on the hydrolysis device 100 , and the visual mirror 190 is used to observe the reaction conditions in the hydrolysis device 100 .

[0037] Specifically, Figure 1 and Figure 2 As shown, when the hydrolysis device 100 is performing a hydrolysis reaction, the first switch valve 120 and the second switch valve 130 are first closed, antimony trichloride powder is fed into the hydrolysis device 100 from the solid feed port 160, and hydrochloric acid is introduced from the first liquid inlet 170. The antimony trichloride powder first reacts with the hydrochloric acid, and at the same time, the agitator 800 is turned on for stirring to make the reaction more complete.

[0038] Secondly, if Figure 1 and Figure 2 As shown, after sufficient reaction, the first heater 610 is controlled to heat the hydrolysis device, and concentrated ammonia water is introduced from the second liquid inlet 180, and the agitator 800 and the pH meter 500 work simultaneously, and the pH value and temperature in the hydrolysis device 100 are monitored in real time while the reaction is sufficient, so as to maintain the pH value and temperature required for hydrolysis, so as to better perform the hydrolysis reaction. By providing the agitator 800, this embodiment can make the hydrolysis reaction more thorough, thereby improving production efficiency and reducing the waste of raw materials.

[0039] Alternatively, if Figure 1 and Figure 2 As shown, a first waste liquid flow sensor 171 is provided at the first liquid inlet 170, and the first waste liquid flow sensor 171 is used to monitor the amount of hydrochloric acid entering, so as to control the hydrochloric acid and antimony trichloride to react better. A second waste liquid flow sensor 181 is provided at the second liquid inlet 180, and the second waste liquid flow sensor 181 is used to monitor the amount of concentrated ammonia water entering, so as to control the concentrated ammonia water to react better with hydrochloric acid and antimony trichloride.

[0040] Furthermore, if Figure 1 and Figure 2 As shown, after the hydrolysis reaction is completed, the agitator 800 is turned off, the first switch valve 120 is opened, and the waste liquid flows from the first waste liquid discharge port 140 to the waste liquid collection box 200. Because the first filter element 110 is provided at the first switch valve 120, the waste liquid in the hydrolysis device 100 will flow to the waste liquid collection box 200, but the precipitate will not. At this time, the water level in the hydrolysis device 100 can be observed through the visual mirror 190. When the waste liquid has flowed out, the liquid spraying assembly 700 is opened, for example, two high-pressure nozzles are opened first to clean the precipitate in the hydrolysis device 100. After cleaning, the high-pressure nozzle is turned off, and four low-pressure nozzles are opened to wash the precipitate with water. The agitator is turned on while washing with water. At this time, the first switch valve 120 is always in an open state.

[0041] Secondly, if Figure 1 and Figure 2 As shown, after the water washing is completed, the first switch valve 120 is closed, and the four low-pressure nozzles continue to work. When the water level in the hydrolysis device 100 reaches a certain value, the second switch valve 130 and the third switch valve 320 are opened, and the sediment and waste liquid in the hydrolysis device 100 will flow from the hydrolysis product discharge port 150 to the drying device 300, and the waste liquid flowing to the drying device 300 will continue to flow from the second waste liquid discharge port 360 to the waste liquid collection box 200, because the second waste liquid discharge port 360 is provided with a second filter element 310, thus, only the waste liquid will flow out from the second waste liquid discharge port 360, and the sediment will not. In this embodiment, through the cooperation between the first switch valve 120, the second switch valve 130 and the third switch valve 320, the waste liquid and the sediment can be better separated to avoid their mutual mixing, thereby affecting the purity of the product.

[0042] Alternatively, if Figure 2 and Figure 3 As shown, a liquid level meter 230 is provided on the waste liquid collection box 200, and the liquid level meter 230 is used to monitor the height of the waste liquid in the waste liquid collection box 200. In this embodiment, a waste liquid outlet 240 is provided at the bottom of the waste liquid collection box 200, for example, and a sixth switch valve 241 is provided at the waste liquid outlet 240. When the liquid level meter 230 monitors that the waste liquid in the waste liquid collection box 200 reaches a certain height, the sixth switch valve 241 can be opened, thereby allowing the waste liquid to flow out from the waste liquid outlet 240.

[0043] like Figure 1 and Figure 2As shown, the bottom of the hydrolysis device 100 is, for example, in an inverted funnel shape, for example, the bottom of the hydrolysis device 100 is in a shape that is concave from bottom to top. The first waste liquid discharge port 140 and the hydrolyzate discharge port 150 are respectively arranged at the two ends of the bottom of the hydrolysis device 100. In this embodiment, the bottom of the hydrolysis device 100 is arranged in an inverted funnel shape, so that after the hydrolysis reaction is completed, when the waste liquid flows from the first waste liquid discharge port 140 into the waste liquid collection box 200, the hydrolysis device 100 can be tilted toward one end close to the first waste liquid discharge port 140, so that the waste liquid can flow out from the first waste liquid discharge port 140. When the washed waste liquid and precipitate flow from the hydrolyzate discharge port 150 to the drying device 300, the hydrolysis device 100 can be tilted toward one end close to the hydrolyzate discharge port 150, so that the waste liquid and precipitate can flow out from the hydrolyzate discharge port 150. This setting can prevent the waste liquid and sediment from mixing together, thereby ensuring the smooth discharge of the filtrate while also facilitating the discharge of the sediment, thereby improving the purity of the sediment.

[0044] like Figure 1 and Figure 3 As shown, the drying device 300 is provided with a second temperature control component, for example. The second temperature control component is used to heat the drying device 300 and monitor the temperature inside the drying device 300. Specifically, the second temperature control component includes, for example, a second thermocouple 380 and a second heater 390. The second heater 390 heats the drying device 300, and when the second thermocouple 380 monitors that the temperature inside the drying device 300 meets the temperature required for drying, the second heater 390 stops heating.

[0045] Alternatively, if Figure 1 and Figure 3 As shown, for example, a scraper 370 is provided in the drying device 300, and the scraper 370 is used to scrape the material in the drying device 300 to the drying material outlet 350. The drying material is, for example, ultrafine antimony trioxide. Secondly, a motor 371 is also provided on the drying device 300, and the motor 371 is connected to the scraper 370, and the scraper 370 can rotate under the drive of the motor. Optionally, the scraper 370 is, for example, arranged in a curved spiral, and this arrangement of the scraper 370 can move the sediment at the inner edge of the drying device 300 to the center position, and the scraper 370 is driven by the rotation of the motor 371 to scrape the sediment from the drying material outlet 350, and then flow to the reduction device 400. By setting the scraper 370, the sediment can be scraped out more quickly in this embodiment, thereby improving production efficiency.

[0046] like Figure 1 and Figure 3As shown, for example, a first collecting box 420 is provided between the drying device 300 and the reducing device 400, and the fourth switch valve 330 is provided between the first collecting box 420 and the dried product discharge port 350. Specifically, for example, when the sediment is drying in the drying device 300, the fourth switch valve 330 is in a closed state. When the sediment is dried, the fourth switch valve 330 is opened, and the motor 371 is turned on. The motor 371 drives the scraper 370 to rotate, so that the scraper 370 can scrape the sediment from the dried product discharge port 350 and flow to the first collecting box 420, and then flow from the first collecting box 420 to the reducing device 400.

[0047] Furthermore, if Figure 1 and Figure 3 As shown, a third temperature control component is provided on the reduction device 400. The third temperature control component is used to heat the reduction device 400 and monitor the temperature inside the reduction device 400. Specifically, the third temperature control component includes, for example, a third thermocouple 450 and a third heater 440. The third heater 440 heats the reduction device 400, and when the third thermocouple 450 monitors that the temperature inside the reduction device 400 meets the temperature required for the reduction reaction, the third heater 440 stops heating. Secondly, a hydrogen inlet 460 is provided on the reduction device 400, and the hydrogen inlet 460 is connected to the hydrogen bottle 900.

[0048] like Figure 1 and Figure 3 As shown, a second collection box 430 is provided at the bottom of the reduction device 400, and a fifth switch valve 431 is provided between the second collection box 430 and the reduction device 400. Specifically, for example, when the precipitate and hydrogen undergo a reduction reaction in the reduction device 400, the fifth switch valve 431 is in a closed state. When the reduction reaction is completed, the fifth switch valve 431 is opened, and at this time, the antimony product produced by the reduction reaction can flow to the second collection box. Among them, the antimony product obtained by the reduction reaction is, for example, ultrafine high-purity antimony. Optionally, an airflow controller 910 is provided between the reduction device 400 and the hydrogen bottle 900. The airflow controller 910 is used to achieve precise control of the flow rate of hydrogen, to avoid waste caused by too fast a hydrogen flow rate or failure to achieve the expected reduction effect due to too slow a flow rate, thereby ensuring the full progress of the reduction reaction and achieving full utilization of the material.

[0049] The embodiment of the utility model integrates the hydrolysis device 100, the waste liquid collection box 200, the drying device 300 and the reduction device 400 so that the hydrolysis-drying-reduction reaction can be completed in the same device, thereby reducing the entry of impurities, thereby ensuring the purity of the antimony product in the production process. Secondly, the embodiment integrates the equipment so that the equipment is simple and easy to operate, stable and reliable, has low manufacturing cost, low energy consumption, high safety, and can achieve continuous production, so that the equipment is suitable for large-scale production.

[0050] Secondly, by setting up the airflow controller 910, the flow rate of hydrogen can be controlled to avoid the situation where the hydrogen flow rate is too slow and the reaction is insufficient, or the flow rate is too fast and the gas is difficult to form a reverse reaction. In addition, the hydrolysis device 100, the drying device 300 and the reduction device 400 are respectively provided with temperature control components to prevent the device from being damaged by excessive temperature, thereby improving the safety of the device.
