An apparatus for preparing a lithium iron phosphate material

Abstract

This utility model discloses an apparatus for preparing lithium iron phosphate materials, relating to the field of lithium iron phosphate preparation technology. The apparatus includes a storage tank, with an activation silo fixedly connected to its bottom. An electric actuator is fixedly connected inside the diversion cone of the activation silo, and a mounting block is fixedly connected to the movable end of the electric actuator. A vibration transmission rod is rotatably connected to the top of the diversion cone, and a connecting rod is provided between the vibration transmission rod and the mounting block. By using the electric actuator and the vibration transmission rod, the apparatus can drive the mounting block to move, thereby pushing the vibration transmission rod outward through the connecting rod transmission. This allows the vibration transmission rod to form a larger vibration area at the top of the diversion cone, thus enhancing the range and effect of the vibration. When the activation silo vibrates, the vibration transmission rod also vibrates accordingly, creating vibrations at multiple locations, which can more effectively break down bridging in the lithium iron phosphate raw material and promote smooth material flow.

Description

Technical Field

[0001] This utility model relates to the field of lithium iron phosphate preparation technology, specifically to an apparatus for preparing lithium iron phosphate materials. Background Technology

[0002] Lithium iron phosphate (LFP) is a new generation of lithium-ion batteries that can power hybrid electric vehicles and pure electric vehicles. It can also store energy from wind and solar power to solve the intermittent problem of smart grids. One preparation process involves uniformly mixing lithium carbonate, carbon source, and iron phosphate, then adding ethanol for ball milling, followed by drying, sintering, and pulverizing to produce lithium iron phosphate. This process offers more relaxed reaction conditions, stronger controllability, simpler production equipment, lower process barriers, and allows for precise control of structure and morphology using wet chemical methods. The product particle size can be controlled to be fine, and the grain morphology is regular and near-spherical.

[0003] Existing equipment for preparing lithium iron phosphate materials uses storage tanks for material storage. However, if the lithium iron phosphate is not stored properly, such as being exposed to a humid environment or other adverse conditions, the interaction forces between particles may be enhanced, resulting in bridging. This will affect the discharge operation of the normal production and lead to the interruption of subsequent product production. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide an apparatus for preparing lithium iron phosphate materials, so as to solve the technical problem that the discharge operation will affect the normal production and thus lead to the interruption of subsequent product production.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an apparatus for preparing lithium iron phosphate materials, comprising a storage tank, an activation hopper fixedly connected to the bottom of the storage tank, an electric push rod fixedly connected inside the diversion cone of the activation hopper, and an installation block fixedly connected to the movable end of the electric push rod;

[0006] The top of the flow-changing cone is rotatably connected to a vibration-transmitting rod, and a connecting rod is provided between the vibration-transmitting rod and the mounting block.

[0007] By adopting the above technical solution, the electric actuator is cleverly installed inside the diversion cone of the activation hopper and fixedly connected to the mounting block through its movable end. When the electric actuator is started, it can drive the mounting block to move, which not only realizes mechanized operation, but also improves the automation level of the equipment.

[0008] Furthermore, four vibration transmission rods are provided, and the four vibration transmission rods are arranged in a circular array along the central axis of the flow-changing cone.

[0009] By adopting the above technical solution, the circular array arrangement of the four vibration transmission rods allows the vibration energy to be transmitted more evenly to the iron phosphate raw material in the storage tank, avoiding local concentration of vibration energy and ensuring that the material in the entire lower part of the silo is effectively vibrated, thereby more comprehensively breaking the bridging phenomenon and improving the flowability of the material.

[0010] Furthermore, the vibration transmission rod and the connecting rod are rotatably connected, and the vibration transmission rod is arranged in a "7" shape.

[0011] By adopting the above technical solution, the rotational connection between the vibration transmission rod and the connecting rod allows the vibration transmission rod to rotate and open flexibly under the drive of the connecting rod, enabling the vibration transmission rod to better adapt to storage tanks of different shapes and sizes, thereby improving the versatility and adaptability of the equipment.

[0012] Furthermore, the electric actuator is electrically connected to an external power supply device via a cable.

[0013] By adopting the above technical solution, the electrical connection between the electric actuator and the external power supply equipment ensures that the electric actuator can obtain a stable and reliable power supply, enabling the electric actuator to work continuously and stably, thereby ensuring the normal operation of the equipment and efficient production.

[0014] Furthermore, the storage tank is externally fixedly connected to a bracket, and the top of the storage tank is fixedly connected to a protective net.

[0015] By adopting the above technical solution, the fixed connection of the bracket provides stable support for the storage tank, ensuring the stability and safety of the storage tank during operation, and also enabling the equipment to better adapt to different working environments and installation conditions.

[0016] Furthermore, one side of the vibration transmission rod is provided with an inclined surface, and there are two inclined surfaces, which are arranged in a knife-edge structure.

[0017] By adopting the above technical solution, the inclined surface reduces the frictional resistance between the vibration rod and the surrounding structure during the opening and vibration process. Since the inclined surface has a blade-like structure, its sharp edge can cut and disperse materials more effectively, thereby reducing the driving force required for the vibration rod to move and improving the energy efficiency of the equipment.

[0018] In summary, the present invention has the following main advantages:

[0019] 1. This utility model, by setting an electric push rod and a vibration transmission rod, can drive the mounting block to move, and then push the vibration transmission rod to open outward through the linkage transmission, so that the vibration transmission rod can form a large vibration area at the top of the flow-changing cone, thereby enhancing the range and effect of vibration. When the activation silo vibrates, the vibration transmission rod will also vibrate, and vibration will be formed at multiple positions, which can more effectively break the bridging phenomenon in the iron phosphate raw material, promote the smooth flow of materials, and thus improve the quality of lithium iron phosphate materials.

[0020] 2. By setting an inclined surface, this utility model can effectively reduce the contact area with the surrounding structure during the opening process of the vibration transmission rod, thereby reducing the driving force required for opening and reducing energy consumption.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0027] The embodiments of this utility model will be described below based on its overall structure.

[0028] Example 1:

[0029] An apparatus for preparing lithium iron phosphate materials, such as Figures 1-4 As shown, it includes a storage tank 1, an activation silo 2 is fixedly connected to the bottom of the storage tank 1, an electric push rod 4 is fixedly connected inside the diversion cone 3 of the activation silo 2, and an installation block 5 is fixedly connected to the movable end of the electric push rod 4.

[0030] A vibration transmission rod 6 is rotatably connected to the top of the diversion cone 3. A connecting rod 7 is provided between the vibration transmission rod 6 and the mounting block 5. The vibration transmission rod 6 is connected to the mounting block 5 through the connecting rod 7 and can rotate at the top of the diversion cone 3. When the mounting block 5 moves, the connecting rod 7 will drive the vibration transmission rod 6 to open at the top of the diversion cone 3, forming a larger vibration area. This not only expands the range of vibration but also improves the uniformity of vibration, thereby more effectively breaking the bridging phenomenon in the raw materials and promoting the smooth flow of materials.

[0031] See Figure 3 There are four vibration transmission rods 6, which are arranged in a ring array along the central axis of the flow-changing cone 3. The four vibration transmission rods 6 work together to form a stronger vibration effect. Compared with a single vibration transmission rod, the simultaneous vibration of multiple vibration transmission rods can produce a larger vibration amplitude and a wider vibration range, thereby more effectively breaking the static friction and adhesion between materials and promoting the smooth discharge of materials.

[0032] See Figure 3 The vibration transmission rod 6 and the connecting rod 7 are rotatably connected. The vibration transmission rod 6 is set in a "7" shape. The "7" shape of the vibration transmission rod 6 allows it to form a larger vibration area when it is opened, which not only expands the range of vibration but also improves the uniformity and effectiveness of vibration, thereby more comprehensively breaking the bridging phenomenon and promoting the smooth flow of materials.

[0033] See Figure 3 The electric actuator 4 is electrically connected to an external power supply device via cable 8. This connection allows for remote control of the electric actuator 4, which not only improves the automation level of the equipment but also enables operators to monitor and operate the equipment from a safe area away from the equipment, thereby reducing operational risks and improving production safety.

[0034] See Figure 3 The storage tank 1 is externally fixedly connected to a bracket 9, and the top of the storage tank 1 is fixedly connected to a protective net 10. The combined use of the protective net 10 and the bracket 9 provides convenience for the maintenance and repair of the equipment. Operators can safely carry out the inspection and repair work of the equipment under the protection of the protective net 10.

[0035] The implementation principle of this utility model is as follows: First, the iron phosphate raw material is stored in the storage tank 1. When it is necessary to discharge the material, the electric push rod 4 is activated. The electric push rod 4 obtains power from the external power supply equipment through the cable 8 and drives the mounting block 5 to move. The movement of the mounting block 5 is transmitted through the connecting rod 7, which pushes the vibration transmission rod 6 to open outward, so that the vibration transmission rod 6 opens at the top of the flow-changing cone 3 to form a large area. Then, the activation hopper 2 is activated for a short time. The activation hopper 2 vibrates, which drives the vibration transmission rod 6 to vibrate, so that vibration can be formed at multiple positions, breaking the bridging phenomenon and promoting the smooth flow of materials. Then, the electric push rod 4 is activated to retract the vibration transmission rod 6 and continue to discharge normally.

[0036] Example 2:

[0037] See Figure 4 The vibration transmission rod 6 has an inclined surface 11 on one side. There are two inclined surfaces 11, which are arranged in a knife-edge structure. The inclined surfaces 11 also help to improve the arch breaking effect of the equipment. When the vibration transmission rod 6 vibrates, the inclined surfaces 11 can more effectively transfer the vibration energy to the material, thus improving the effectiveness of the vibration.

[0038] The implementation principle of this utility model is as follows: First, the inclined surface 11 on one side of the vibration transmission rod 6 reduces the resistance when the vibration transmission rod 6 opens, thus reducing the resistance on the connecting rod 7.

[0039] All parts not covered in this utility model are the same as or can be implemented using existing technologies, and will not be described in detail here.
