It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0021] The utility model embodiment provides a sodium ion removal reactor, such as Figure 1-4As shown, the reactor for sodium ion removal comprises: a reactor body 1 for sodium ion removal, the reactor body 1 is provided with a removal chamber 2 and a filter chamber 3 which are connected and distributed up and down; an electric heating block 4, the electric heating block 4 is arranged on the inner wall of the removal chamber 2 for heating; a stirring rod 5, the stirring rod 5 is rotatably mounted on the reactor body 1, and the bottom end of the stirring rod 5 extends into the removal chamber 2 for stirring the sodium ion solution to be removed; a first motor 6, the first motor 6 is fixedly mounted on the top of the reactor body 1, and the output shaft of the first motor 6 is fixedly connected to the top of the stirring rod 5 through a coupling; a detachable filter basket 7, the filter basket 7 is arranged in the filter chamber 3 for filtering the liquid after the sodium ions are removed; a first drain pipe 8 for discharging liquid into the filter basket 7, the first drain pipe 8 is fixedly connected to the bottom of the removal chamber 2, and a first solenoid valve 9 is arranged on the first drain pipe 8; a cleaning mechanism for cleaning impurities in the filter basket 7, the cleaning mechanism is arranged on the filter basket 7.

[0022] It should be noted that there are various methods for producing ferric phosphate, among which the sodium method and the ammonia method (or ammonium method) are the two mainstream processes. The sodium method, also known as the phosphoric acid method, mainly uses raw materials such as phosphoric acid, liquid alkali (such as sodium hydroxide) and ferrous sulfate to react and adjust the pH value to produce ferric phosphate. This process is widely used because its raw materials are easily available and the cost is relatively low. However, the traditional sodium method does face some challenges in the synthesis of ferric phosphate dihydrate, especially in controlling the sodium ion content; in the sodium method, raw materials such as phosphoric acid and liquid alkali themselves contain a certain amount of sodium ions. These sodium ions may not fully participate in the reaction during the reaction, or enter the final product through certain side reactions, resulting in excessive sodium ion content in ferric phosphate; in the reaction process, pH adjustment is one of the key steps. However, even with the use of precise pH control equipment, pH fluctuations may occur due to improper operation or equipment accuracy limitations, which in turn affects the removal effect of sodium ions; although the sodium ion content in the product can be reduced through subsequent separation and purification steps, these steps often increase production costs and process complexity. At the same time, existing separation and purification technologies may not be able to completely remove all sodium ions, resulting in a certain amount of sodium ions in the final product; excessive sodium ions will directly affect the purity of iron phosphate, reducing its performance as a battery material or in other application areas. For example, in the battery industry, the purity of iron phosphate has an important impact on key indicators such as battery energy density, cycle life and safety; due to the high purity requirements of downstream customers for iron phosphate materials, excessive sodium ions may cause the product to fail to meet customer needs, thereby affecting the market competitiveness and customer satisfaction of the product. Based on the above, a sodium ion removal reactor is needed to solve the above problems;

[0023] In this embodiment, the reactor body 1 is the core frame of the whole equipment, carrying all functional components; the removal chamber 2 is the main place where the sodium ion removal reaction occurs.

This design not only simplifies the transmission structure, but also improves the stirring efficiency; the detachable filter basket 7 is arranged in the filter chamber 3, which is used to filter the liquid after the sodium ions are removed. Its detachable design is convenient for cleaning and replacement, and ensures the filtering effect; the first drain pipe 8 introduces the liquid in the removal chamber 2 into the filter chamber 3 for filtering. By setting the first solenoid valve 9, the drainage time and flow rate can be accurately controlled to ensure the smooth progress of the filtration process; the cleaning mechanism is used to regularly clean the impurities in the filter basket 7 to prevent blockage and affect the filtration effect; when removing sodium ions, the dihydrate iron phosphate with a relatively high sodium ion content (150-300ppm) after conventional washing is re-pulped, and the re-pulping concentration is adjusted to 20%-30% to ensure the uniformity and efficiency of the subsequent reaction; the re-pulped dihydrate iron phosphate slurry is sent into the removal chamber 2 of the reactor body 1 to prepare for the deep removal of sodium ions; the slurry is heated to 80±5°C by the electric heating block 4, and the acidification reaction is promoted by the increase in temperature; at the same time, a certain amount of sulfuric acid is added to the slurry. By precisely controlling the amount of addition, the pH value of the slurry is adjusted to 0.5±0.5. This step is the key to removing sodium ions. The sodium ions are converted into soluble sodium salts through the acidification reaction. The first motor 6 drives the stirring rod 5 to rotate, and the bottom end of the stirring rod 5 fully stirs the slurry in the removal chamber 2 to ensure that the sulfuric acid and the slurry are evenly mixed, thereby improving the efficiency and uniformity of the acidification reaction. After the acidification reaction is completed, the liquid containing the soluble sodium salt is discharged into the filter basket 7 in the filter chamber 3 through the first drainage pipe 8. The first solenoid valve 9 controls the drainage process to ensure that the drainage is smooth and easy to control. The filter basket 7 filters the liquid to intercept the solid impurities and incompletely dissolved substances therein, and the solution containing the removed sodium ions is discharged through the filter basket 7.
