Description

Technical Field

[0001] This application relates to the field of anhydrous ferric phosphate processing technology, specifically to a raw material feeding device for anhydrous ferric phosphate processing. Background Technology

[0002] Anhydrous ferric phosphate is an iron-containing inorganic compound with the chemical formula FePO4. It exists in two crystal structures: monoclinic and orthorhombic. At room temperature, it is monoclinic and exhibits excellent stability and thermal stability, making it an important catalyst material. It has a wide range of applications, particularly in batteries, catalysts, electronic materials, and ceramic materials. The production process of anhydrous ferric phosphate requires strict control over purity, particle size distribution, morphology, and crystallinity to ensure the performance of the final battery material. The following are the main industrial production processes, typically employing a liquid-phase precipitation method. Ferrous sulfate (FeSO4·7H2O) or ferrous nitrate (Fe(NO3)2), along with phosphoric acid (H3PO4) or ammonium dihydrogen phosphate (NH4H2PO4), are usually introduced into the reaction vessel for processing.

[0003] When anhydrous ferric phosphate is produced, the raw materials ferrous sulfate or phosphoric acid are usually directly piped into the reactor. However, if the ferrous sulfate is not pure enough or is improperly stored, it may contain trace amounts of insoluble solid impurities (silicate, aluminate particles, etc. from the ore). Directly piped the raw materials into the reactor to produce ferric phosphate makes it difficult to remove impurities and can easily reduce the quality of ferric phosphate.

[0004] Therefore, there is an urgent need for a raw material feeding device for anhydrous ferric phosphate processing to solve the problem that the feeding device is inconvenient for removing impurities from the raw material. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a raw material feeding device for anhydrous ferric phosphate processing, which has the advantage of improving the purity of anhydrous ferric phosphate and solves the problem that the feeding device is inconvenient for removing impurities from the raw material.

[0006] To achieve the above objectives, this application provides the following technical solution: a raw material feeding device for processing anhydrous ferric phosphate, comprising a reaction vessel, a connecting pipe, a filter box, and a feed pipe, wherein the two ends of the connecting pipe are connected to the outer surface of the reaction vessel and the bottom of the filter box, the feed pipe is installed on the top of the filter box, a mixing mechanism is provided inside the reaction vessel, and a filtering mechanism is provided inside the filter box;

[0007] The mixing mechanism includes a drive motor, a connecting rod, and a filter element. The drive motor is mounted on a plate on the outside of the filter box. One end of the connecting rod is fixedly connected to the output end of the drive motor. The filter element includes a filter cylinder, a connecting sleeve, a support rod, and a filter screen. Both ends of the support rod are welded to the inside of the filter cylinder. The filter screen is disposed on the outer surface of the filter cylinder. The other end of the connecting rod is fixedly connected to one end of the filter cylinder by bolts. The connecting sleeve is rotatably connected to the outer surface of the filter cylinder. The filter cylinder is connected to the feed pipe.

[0008] Ferrous sulfate enters the filter cylinder through the connecting sleeve. As the filter cylinder rotates, the filter screen on the outside of the filter cylinder filters out impurities in the ferrous sulfate, thereby reducing the impurities in the ferrous sulfate and improving the purity of anhydrous ferric phosphate.

[0009] Preferably, a fixing cylinder is fixedly installed inside the filter box, and a flexible hose is installed outside the fixing cylinder. The outer ends of the filter cylinder are rotatably connected to the inside of the reaction vessel.

[0010] Preferably, the filter cartridge is connected to the connecting sleeve via a bearing.

[0011] Preferably, the mixing mechanism includes a second drive motor, a second connecting rod, a stirring blade, a scraper groove, and a drain hole. The second drive motor is installed on the top of the reactor. One end of the second connecting rod is fixedly connected to the output end of the second drive motor. The stirring blade is welded to the outer surface of the second connecting rod. The scraper groove is opened on both sides of the stirring blade, and the drain hole is set on both sides of the stirring blade.

[0012] Preferably, a support rod two is welded to the outer surface of the connecting rod two, and a connecting plate is fixedly connected to the outer side of the support rod two by bolts. A scraper is welded to the bottom of the connecting plate, and the scraper is an arc-shaped plate.

[0013] Preferably, a support plate is rotatably connected to the outer surface of the connecting rod 2, and the support plate is fixedly connected to the inner surface of the reactor by bolts.

[0014] Preferably, the scraper groove has an outwardly inclined opening.

[0015] In summary, this application includes at least one of the following beneficial effects:

[0016] 1. In this raw material feeding device for anhydrous ferric phosphate processing, when ferrous sulfate is fed into the filter box through the feed pipe, the ferrous sulfate enters the filter cylinder through the connecting sleeve. When the filter cylinder drives the filter screen to rotate, the filter screen on the outside of the filter cylinder filters the impurities in the ferrous sulfate, thereby reducing the impurities in the ferrous sulfate and improving the purity of anhydrous ferric phosphate.

[0017] 2. In this raw material feeding device for anhydrous ferric phosphate processing, when the raw material for anhydrous ferric phosphate is introduced into the reactor, the connecting rod two drives the stirring blade and the support rod two to rotate. The support rod two drives the scraper to rotate through the connecting plate. When the scraper rotates, it pushes the anhydrous ferric phosphate raw material on the outside to the outside through the scraper. The anhydrous ferric phosphate raw material moves up or down along the inner wall of the reactor. The scraper pushes the anhydrous ferric phosphate raw material below upwards, thereby forming a circulation of the flow of the anhydrous ferric phosphate raw material, making the anhydrous ferric phosphate raw material more thoroughly mixed and improving the quality of anhydrous ferric phosphate.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] Please see Figure 1-5A raw material feeding device for anhydrous ferric phosphate processing includes a reaction vessel 1, a connecting pipe 2, a filter box 3, and a feed pipe 4. The two ends of the connecting pipe 2 are connected to the outer surface of the reaction vessel 1 and the bottom of the filter box 3. The feed pipe 4 is installed on the top of the filter box 3. The raw material of anhydrous ferric phosphate is fed into the filter box 3 through the feed pipe 4. The reaction vessel 1 is equipped with a mixing mechanism, and the filter box 3 is equipped with a filtration mechanism. The filtration mechanism filters impurities in the raw material of anhydrous ferric phosphate. The filtered raw material of anhydrous ferric phosphate enters the reaction vessel 1 through the connecting pipe 2.

[0026] Specifically, the mixing mechanism includes a drive motor 111, a connecting rod 112, and a filter element 113. The drive motor 111 is mounted on the outer plate of the filter box 3. One end of the connecting rod 112 is fixedly connected to the output end of the drive motor 111. The filter element 113 includes a filter cylinder 114, a connecting sleeve 117, a support rod 118, and a filter screen 119. Both ends of the support rod 118 are welded to the inner side of the filter cylinder 114. The filter screen 119 is set on the outer surface of the filter cylinder 114. The other end of the connecting rod 112 is fixedly connected to one end of the filter cylinder 114 by bolts. The connecting sleeve 117 is rotatably connected to the outer surface of the filter cylinder 114. The filter cylinder 114 is connected to the feed pipe 4. A fixed cylinder 115 is fixedly installed inside the filter box 3. A flexible hose 116 is installed on the outside of the fixed cylinder 115. The outer ends of the filter cylinder 114 are rotatably connected to the inside of the reactor 1. The filter cylinder 114 is connected to the connecting sleeve 117 through bearings.

[0027] Through the above technical solution, when ferrous sulfate is introduced into the filter box 3 through the feed pipe 4, the drive motor 111 is started. The drive motor 111 drives the connecting rod 112 to rotate. When the connecting rod 112 rotates, it drives the filter cylinder 114 to rotate. Ferrous sulfate enters the filter cylinder 114 through the connecting sleeve 117. When the filter cylinder 114 drives the filter screen 119 to rotate, the filter screen 119 on the outside of the filter cylinder 114 filters the impurities in the ferrous sulfate, thereby reducing the impurities in the ferrous sulfate and improving the purity of anhydrous ferric phosphate.

[0028] When water is introduced into the feed pipe 4, the water enters the filter cylinder 114 through the connecting sleeve 117. The water washes away the impurities inside the filter cylinder 114, and the impurities are discharged through the hose 116.

[0029] Specifically, the mixing mechanism includes a second drive motor 211, a second connecting rod 212, a stirring blade 213, a scraper trough 214, and a drain hole 215. The second drive motor 211 is installed on the top of the reactor 1. One end of the second connecting rod 212 is fixedly connected to the output end of the second drive motor 211. The stirring blade 213 is welded to the outer surface of the second connecting rod 212. The scraper trough 214 is opened on both sides of the stirring blade 213. The scraper trough 214 has an outwardly inclined opening. The drain hole 215 is located on both sides of the stirring blade 213. A second support rod 216 is welded to the outer surface of the second connecting rod 212. A connecting plate 217 is fixedly connected to the outer side of the second support rod 216 by bolts. A scraper 218 is welded to the bottom of the connecting plate 217. The scraper 218 is an arc-shaped plate. A support plate 219 is rotatably connected to the outer surface of the second connecting rod 212. The support plate 219 is fixedly connected to the inner surface of the reactor 1 by bolts.

[0030] Through the above technical solution, when the raw material of anhydrous ferric phosphate is introduced into the reactor 1, the second drive motor 211 is started. The second drive motor 211 drives the second connecting rod 212 to rotate. The second connecting rod 212 drives the stirring blade 213 and the second support rod 216 to rotate. The second support rod 216 drives the scraper 218 to rotate through the connecting plate 217. When the scraper trough 214 rotates, it pushes the anhydrous ferric phosphate raw material on the outside to the outside. The anhydrous ferric phosphate raw material moves up or down along the inner wall of the reactor 1. The scraper 218 pushes the anhydrous ferric phosphate raw material below upward, so that the flow of the anhydrous ferric phosphate raw material forms a circulation, making the anhydrous ferric phosphate raw material more thoroughly mixed and improving the quality of anhydrous ferric phosphate.

[0031] The support plate 219 supports the connecting rod 212, allowing the connecting rod 212 to rotate stably.

[0032] In use, ferrous sulfate enters the filter cylinder 114 through the connecting sleeve 117. When the filter cylinder 114 drives the filter screen 119 to rotate, the filter screen 119 on the outside of the filter cylinder 114 filters the impurities in the ferrous sulfate, thereby reducing the impurities in the ferrous sulfate and improving the purity of anhydrous ferric phosphate.
