Description

Technical Field

[0001] This utility model relates to the field of ferric phosphate preparation technology, specifically a temperature-controlled reaction tank for preparing low-impurity ferric phosphate. Background Technology

[0002] A reaction vessel for preparing ferric phosphate, with authorization announcement number "CN 218981563 U", has a top cover and a bottom cover fixedly connected to the top and bottom of the outer shell, respectively. The feeding assembly includes a feeding chamber, a second motor, and a crushing roller. The heating assembly includes a sleeve fitted on the outer wall of the outer shell and a heating tube disposed inside the outer shell. This invention, through the feeding assembly, utilizes the second motor and crushing roller within the feeding assembly to perform secondary crushing of the raw materials, thereby reducing the volume of the raw materials, accelerating the reaction rate, and solving the problem of slow reaction rates in existing systems. Simultaneously, through the heating assembly, the sleeve recovers and utilizes the residual heat within the heating tube, and insulates the reaction inside the outer shell, solving the problem of low heat utilization efficiency in existing systems.

[0003] This equipment can solve the problem of low heat utilization efficiency, but the temperature of the equipment needs to be easily adjusted during the preparation process. After the temperature reaches the first processing temperature, there is no backup clean water or refrigeration device to replace and cool the hot clean water, which makes it unusable in subsequent reaction processes, thus affecting the reaction efficiency of the equipment and increasing the working time of the equipment. Moreover, the prolonged heating of clean water may cause evaporation after the water reaches the boiling point, resulting in water consumption and reducing working efficiency. In addition, the stirring blade in the equipment is located at the bottom of the stirring chamber, and there is only one. As a result, the stirring effect cannot achieve uniform stirring in a short time during use, and it is not possible to quickly and uniformly stir the material at the top of the stirring chamber. This leads to a long overall working time of the equipment during use, resulting in low practicality and applicability of the equipment. Therefore, this utility model is proposed.

The electrical components in the device need to be powered, and the device needs to be installed on a flat ground to ensure normal operation.

[0029] like Figure 1-Figure 4 As shown, this utility model provides a technical solution: a temperature-controlled reaction tank for preparing low-impurity iron phosphate, comprising:

[0030] A temperature-adjusting reaction tank 1 is used to provide different temperatures for the preparation of ferric phosphate. A stirring mechanism 2 is installed inside and at the top of the temperature-adjusting reaction tank 1 to stir the reaction tank. The temperature-adjusting reaction tank 1 includes a tank body 101. A support plate 116 is fixedly connected to one side of the tank body 101 near the bottom. An oil tank 102 is fixedly connected to the top of the support plate 116. A partition 103 is provided inside the oil tank 102, which divides the oil tank 102 into multiple oil chambers. The top and one side of the oil tank 102 near the two sides... Each tank 102 is fixedly connected to a connecting pipe 105, the inner wall of which is connected to the corresponding oil cavity. A first branch pipe 107 is provided at the top of the connecting pipe 105 located at the top of the oil tank 102. A second branch pipe 114 is provided between the other ends of the connecting pipe 105 located on one side of the oil tank 102. A heating pipe 109 is installed inside the tank 101 near one side, with both ends of the heating pipe 109 penetrating the tank 101 to the outer surface.

A extraction pipe 113 is fixedly connected to the input end of the pump 111, and the other end of the extraction pipe 113 is fixedly connected to the surface of a second branch pipe 114. The interior of the extraction pipe 113 and the interior of the second branch pipe 114 are connected. One end of the discharge pipe 108 is fixedly connected to the other end of the heating pipe 109. Fixedly connected to the surface of the first branch pipe 107, the discharge pipe 108 is connected to the interior of the first branch pipe 107.

A stirring rod 206 is disposed between each first connecting rod 205 and each second connecting rod 208. A driving component is disposed at the top of each mounting plate 201, used to drive the first rotating disk 204 to rotate. Each driving component includes... The system includes a rotary motor 202, each of which is mounted on the top of the mounting plate 201. The output end of each rotary motor 202 passes through the mounting plate 201 to the top of the first rotating disk 204. A motor mounting bracket 203 is fixedly connected to the top of each rotary motor 202, and the bottom end of each motor mounting bracket 203 is fixedly connected to the top of the mounting plate 201.

[0033] This structure enables the equipment to stir the inside of the reaction tank during use, increasing the uniformity among multiple materials and ensuring that the efficiency of material fusion is reduced during the reaction, thus ensuring a good reaction and increasing the practicality of the equipment. During use, the rotating motor 202 sequentially drives the first rotating disk 204, the first connecting rod 205, the stirring rod 206, the second connecting rod 208, and the second rotating disk 207 to rotate, achieving the effect of stirring the materials.

[0036] Step 2: Heat to 70-100℃ and react for 1-5 hours. Filter.

[0037] Step 3: Take a sample of the filtrate and test it for phosphorus, iron, and impurities. The iron to phosphorus ratio should be 1:1.0-1.2. If the iron to phosphorus ratio is not within the range, monoammonium phosphate can be added.

[0038] Step 4: Add ammonia (alkaline solution) to the solution to adjust the pH to 0.8-2.5. React at room temperature for 1-3 hours. Filter, then wash the filter cake with water.

[0039] Step 5: Add pure water to the filter cake and slurry it, then add sulfuric acid. The molar ratio of sulfuric acid to ferric phosphate is sulfuric acid:ferric phosphate = 1.1-2.0:1.

[0041] Step 7: Add ammonia (alkaline solution) to the filtrate to adjust the pH to 0.8-2.5. React at room temperature for 1-3 hours. Filter, then wash the filter cake with water.

[0042] Step 8: Add pure water to the filter cake and slurry it. Then add phosphoric acid or a mixture of phosphoric acid and sulfuric acid, heat to 90-95℃, and react for 2-5 hours.

[0043] Step 9: After the material turns white, filter and wash it with a washing conductivity of 1000 μs / cm.
