[0002] Lithium iron phosphate is a lithium-ion battery electrode material, mainly used in various lithium-ion batteries. In the prior art, the production and processing of lithium iron phosphate requires the use of a crushing device to crush the raw materials.

[0003] According to the patent publication 202121166373.8, a product crushing device for lithium iron phosphate production and processing includes a crushing box, a crushing chamber is provided in the crushing box, a first crushing roller and a second crushing roller are provided in the crushing chamber, a second rotating shaft is axially fixed at both ends of the second crushing roller, a second gear is axially fixed at the front end of the second rotating shaft, a slider is rotatably connected to the second rotating shaft through a bearing seat, an arc-shaped slide groove is provided at the front and rear ends of the crushing chamber corresponding to the position of the slider, an arc-shaped limit rod is bolted in the arc-shaped slide groove, the arc-shaped limit rod is slidably connected to the slider, and a first spring and a second spring are sleeved on the arc-shaped limit rod, and a first limit block and a second limit block are threadedly connected on the arc-shaped limit rod. The design of the slider and the arc-shaped slide groove can adjust the crushing gap between the first crushing roller and the second crushing roller; the design of the first spring, the second spring and the first limit block and the second limit block can prevent the raw material from being sandwiched between the first crushing roller and the second crushing roller.

[0004] However, during use, the traditional crushing device design often includes two independently set crushing rollers, which are respectively deployed on both sides of the processing chamber, aiming to implement a one-time crushing process on the input raw materials by rotating in opposite directions. However, this single-pass crushing mechanism has significant limitations, that is, it cannot guarantee that all raw material particles can reach the ideal degree of refinement, and some particles may not be effectively crushed due to insufficient contact or uneven force, which in turn affects the overall crushing efficiency and finished product quality. In addition, in the iron phosphate production process, uniform mixing of raw materials is one of the key steps to ensure the quality of the final product. Unfortunately, in traditional processes, this mixing process often relies on additional, independent mixing equipment to achieve, which not only increases equipment investment and operating costs, but also leads to the need for frequent transfer of raw materials between crushing and mixing processes, which is not only inefficient, but also increases the risk of material contamination and loss. The overall operation process appears to be cumbersome and inefficient. To this end, it is necessary to design a new technical solution to solve it. Summary of the invention

However, this single-pass crushing mechanism has significant limitations, that is, it cannot guarantee that all raw material particles can reach the ideal degree of refinement, and some particles may not be effectively crushed due to insufficient contact or uneven force, thereby affecting the overall crushing efficiency and the technical problem of finished product quality.

[0029] For details, see Figure 2 The crushing assembly includes a first connecting rod 209, a first crushing roller 210, a first crushing tooth 211, and a second crushing tooth 215. The first connecting rod 209 is fixed to the top of the bottom cover 2 of the cylinder. The first crushing roller 210 is installed outside the first connecting rod 209, and a plurality of first crushing teeth 211 are fixed to the outer wall of the first crushing roller 210.

[0031] For further information, see Figure 2The annular crushing assembly includes an L-shaped plate 204, a second connecting rod 203, a second crushing roller 202, and a third crushing tooth 214. The top of the L-shaped plate 204 is connected to a dual-axis motor 205 that passes through the top plate 101 of the device. A second connecting rod 203 is fixed to one side of the bottom of the L-shaped plate 204. The bottom of the second connecting rod 203 extends into the crushing cylinder 201.

[0032] Further, see Figure 2 A water tank 3 is installed on the top of the L-shaped plate 204, and a water pump 301 is connected to the bottom of the water tank 3. The bottom of the water pump 301 passes through the L-shaped plate 204 and is connected to an atomizing nozzle 302. When it is necessary to reduce dust on the crushed particles generated during the raw material crushing process, the water pump 301 is turned on, and the water in the water tank 3 is pumped out by the water pump 301, and the water is atomized and sprayed downward through the atomizing nozzle 302, thereby reducing dust on the crushed particles generated during the crushing process. Moreover, when the L-shaped plate 204 rotates, the water tank 3 and the atomizing nozzle 302 are driven to rotate, thereby atomizing and reducing dust on different positions on the top of the crushing cylinder 201, and the dust reduction mechanism, the crushing mechanism and the mixing mechanism are integrated.

[0033] It is worth noting that see Figure 2 The upper and lower ends of one side of the water tank 3 are both connected with one end of the water pipe 303, and the other end of the water pipe 303 is detachably connected with the first pipe cover 304.

[0034] It is worth noting that see Figure 3 , a rotating rod 403 is connected to the top of the dual-axis motor 205, and the top of the rotating rod 403 extends into the mixing cylinder 4. A plurality of mixing blades 404 are installed at one end of the rotating rod 403 located in the mixing cylinder 4. In the process of the dual-axis motor 205 driving the second crushing roller 202 to move in a circular manner, the plurality of mixing blades 404 in the mixing cylinder 4 will also be driven to rotate. The raw materials in the mixing cylinder 4 can be mixed through the plurality of mixing blades 404, so that the crushing mechanism and the mixing mechanism are integrated, and there is no need to repeatedly transport the raw materials, which saves the need to set up multiple driving devices, saves energy, and solves the problem that the uniform mixing of raw materials in the iron phosphate production process is one of the key steps to ensure the quality of the final product. Unfortunately, in traditional processes, this mixing process often relies on additional, independent mixing equipment to achieve, which not only increases equipment investment and operating costs, but also leads to the need for frequent transportation of raw materials between crushing and mixing processes, which is not only inefficient, but also increases the risk of material pollution and loss, and the overall operation process appears to be cumbersome and inefficient. Technical problems.

The top and side of the mixing cylinder 4 are connected to one end of the material pipe 401, and the other end of the material pipe 401 is detachably connected to a second pipe cover 402.

[0036] It is worth noting that see Figure 4 An annular cavity 216 is provided inside the grinding cylinder 201, and a plurality of grooves are provided on the inner wall of the annular cavity 216. An annular electric heating tube 213 is installed inside the annular cavity 216. A plurality of heating wires 212 are connected to the outer wall of the annular electric heating tube 213. The ends of the plurality of heating wires 212 away from the annular electric heating tube 213 extend into the plurality of grooves. When the ground raw materials need to be dried, the annular electric heating tube 213 and the heating wires 212 are turned on. The annular electric heating tube 213 can generate heat at different positions inside the grinding cylinder 201, so as to dry the raw materials at different positions inside the grinding cylinder 201. At the same time, since the heating wires 212 are extended into the grooves, the heating speed of the inner wall of the grinding cylinder 201 can be increased, thereby further improving the drying effect.

[0037] It is worth emphasizing that see Figure 1 and Figure 2 A support column 103 is fixed on the top of the device bottom plate 1, and a mounting groove 104 is opened on the top of the support column 103. An electric telescopic cylinder 105 is installed inside the mounting groove 104. A device top plate 101 is fixed on the top of the electric telescopic cylinder 105. A control host 102 is installed on the front end of the device bottom plate 1. When the second crushing roller 202 and the third crushing teeth 214 need to be replaced and maintained, the electric telescopic cylinder 105 can be opened, and the electric telescopic cylinder 105 will drive the device top plate 101 to move upward, thereby driving the second crushing roller 202 and the third crushing teeth 214 to move out of the crushing cylinder 201.

[0038] When using a pulverizing device for producing and processing iron phosphate, first turn on the double-axis motor 205, the double-axis motor 205 drives the L-shaped plate 204 to rotate, the L-shaped plate 204 drives the second connecting rod 203, the second connecting rod 203 drives the second pulverizing roller 202 and the third pulverizing teeth 214 to rotate in a circular manner, then turn on the drive motor 207, the drive motor 207 drives the fixing rod 208, the fixing rod 208 drives the bottom cover 2 of the cylinder and the pulverizing cylinder 201 to rotate, the pulverizing cylinder 201 drives the first connecting rod 209 and the first pulverizing roller 210 to rotate, the first pulverizing roller 214 drives the first connecting rod 209 and the first pulverizing roller 210 to rotate. 0 drives the first crushing teeth 211 to rotate, and the rotating first crushing teeth 211 cooperate with the circularly moving third crushing teeth 214 to continuously crush the raw materials at different positions and angles, thereby improving the crushing effect. Moreover, after the crushing cylinder 201 rotates as a whole, the second crushing teeth 215 on the inner wall of the crushing cylinder 201 will be driven to rotate, and cooperate with the circularly moving third crushing teeth 214 to further improve the crushing effect. When it is necessary to reduce dust from the crushed materials generated during the crushing process, the water pump 301 is turned on, and the water in the water tank 3 is pumped out by the water pump 301. The atomizing nozzle 302 is atomized and sprayed downward, so as to reduce dust from the crushed particles generated during the crushing process. Moreover, when the L-shaped plate 204 rotates, the water tank 3 and the atomizing nozzle 302 are driven to rotate, so as to reduce dust from different positions on the top of the crushing cylinder 201. The dust reduction mechanism, the crushing mechanism and the mixing mechanism are integrated. When the dual-axis motor 205 drives the second crushing roller 202 to move in a circular manner, the multiple mixing blades 404 in the mixing cylinder 4 are also driven to rotate. The raw materials in the mixing cylinder 4 can be mixed by the multiple mixing blades 404. The pulverizing mechanism and the mixing mechanism are integrated, so there is no need to repeatedly transport the raw materials, which saves the need to set up multiple driving devices and saves energy. When the pulverized raw materials need to be dried, the annular electric heating tube 213 and the heating wire 212 are turned on. The annular electric heating tube 213 can generate heat at different positions inside the pulverizing cylinder 201 to dry the raw materials at different positions inside the pulverizing cylinder 201. At the same time, since the heating wire 212 is extended into the tank body, the heating speed of the inner wall of the pulverizing cylinder 201 can be increased, further improving the drying effect.
