Description

Technical Field

[0001] This utility model relates to the field of sodium salt battery solid electrolyte production technology, and in particular to a device and processing equipment for breaking up solid electrolyte precursor calcined powder. Background Technology

[0002] Sodium-ion batteries have broad application prospects in the energy storage field due to their high safety, long cycle life, and excellent low-temperature performance. Their core component, the ceramic cell, as a solid electrolyte, plays a decisive role in the overall performance of the battery. This ceramic cell is typically formed using an isostatic pressing process, which requires the raw material (alumina granulated powder) to have excellent flowability to ensure tight packing in the mold, thereby obtaining a high-quality green compact.

[0003] In the preparation of alumina granulated powder, calcination is a crucial step, used to achieve crystal phase transformation and remove impurities. However, the calcined powder generally agglomerates into hard lumps and easily adheres to the inner wall of the supporting sagger, making it unsuitable for direct use in subsequent molding. Therefore, a de-lumping process is necessary to break it down to a suitable particle size.

[0004] Currently, existing methods for breaking up and processing materials have significant drawbacks: incomplete and uneven breaking up can easily lead to bridging and blockage of powder in subsequent conveying pipelines; at the same time, materials are prone to remain on the crushing tools and the inner wall of the crucible during the crushing process, resulting in material loss and seriously affecting the continuity and efficiency of production. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned deficiencies in existing calcined powder breaking technologies by providing a calcined powder breaking device and processing equipment. This calcined powder breaking device, through the integration of a cross-shaped blade and synchronous air vibration, aims to achieve efficient and uniform breaking of calcined lumpy materials, effectively solving the problem of material adhesion to the blades and the inner wall of the crucible, thereby ensuring the continuity and stability of production and improving the overall efficiency of powder post-processing.

[0006] To achieve the above objectives, this utility model provides a calcined powder breaking device, which is installed above a conveyor line for conveying saggers, and includes: a driving mechanism; a blade fixing plate connected to the driving mechanism and driven by the driving mechanism to perform lifting and lowering movements; a cross blade fixedly installed on the blade fixing plate, with the blade tip facing downwards towards the sagger flowing on the conveyor line; and a first air vibration device installed on the blade fixing plate, the first air vibration device and the cross blade lifting and lowering synchronously, and the blade fixing plate forming a vibration transmission path from the first air vibration device to the cross blade.

[0007] The blade of the Phillips head has a symmetrical bevel structure on both sides.

[0008] The inclined plane structure is a 45° inclined plane.

[0009] The cross-shaped cutter is equipped with an additional structure for transmitting vibration.

[0010] The additional structure for transmitting vibration is at least one hole opened in the cross-shaped cutter.

[0011] There are two of the first air vibration devices, which are symmetrically installed on both sides of the cross-shaped insert.

[0012] The cross-shaped insert has a guide structure near the cutter head.

[0013] Another aspect of this utility model provides a calcined powder processing device, including the aforementioned calcined powder breaking device and a material discharge and dust removal device. The material discharge and dust removal device includes: a clamping device located downstream of the calcined powder breaking device; a dust removal box including an inlet and an outlet, the inlet being located on the side wall or top of the dust removal box, and the outlet being located at the bottom of the dust removal box; the clamping device is used to clamp the sagger processed by the calcined powder breaking device and extend it into the inlet to flip and discharge the material; and a blowing knife mechanism located at the upper edge of the inlet to form an airflow barrier.

[0051] See Figure 1 As shown in the figure, an embodiment of the present invention provides a structural diagram of a calcined powder processing device 1, which includes a calcined powder breaking device 10 and a material discharge and dust removal device 11. The calcined powder breaking device 10 is disposed above the conveyor line 3 for conveying the sagger 2, and the material discharge and dust removal device 11 is disposed beside the conveyor line 3. Exemplarily, the calcined powder breaking device 10 can be rigidly fixed to an external support (not shown) located above the conveyor line 3 by a mounting structure on its body (e.g., by bolt connection or flange fixing), thereby ensuring that the blade head 1021 of its cross cutter 102 ( Figure 3 It can stably and accurately align with the sagger 2 flowing below.

[0052] like Figure 2 and Figure 3As shown, the calcined powder breaking device 10 includes: a drive mechanism 100, a blade fixing plate 101, a cross blade 102, and a first air vibration device 103. A mounting part (not shown) may be provided on the housing of the drive mechanism 100, through which the drive mechanism 100 is rigidly fixed to an external support body (e.g., by means of bolts or flanges). The blade fixing plate 101 is connected to the drive mechanism 100 and is driven by the drive mechanism 100 to perform lifting and lowering movements. The top 1020 of the cross blade 102 is fixedly installed on the bottom of the blade fixing plate 101, and the blade tip 1021 of the cross blade 102 faces downwards towards the sagger 2 flowing on the conveyor line 3. The first air vibration device 103 is installed on the bottom of the blade fixing plate 101 and rises and falls synchronously with the cross blade 102. Preferably, there are two first air vibration devices 103, symmetrically installed on both sides of the cross blade 102. Thus, the insert fixing plate 101 forms the vibration transmission path from the first air vibration device 103 to the cross insert 102.

[0053] The drive mechanism 100 is, for example, a cylinder, a hydraulic cylinder, or an electric linear module (such as a servo motor and a ball screw). Figure 2 As shown, in this embodiment, the drive mechanism 100 is a cylinder 1000. The cylinder body of the cylinder 1000 is fixed to the external support body by bolts or flanges (not shown in the figure). The extended end of its piston rod is connected to the inserter fixing plate 101 (not shown in the figure) to drive the inserter fixing plate 101 and the cross inserter 102 and the first air vibration device 103 on it to perform synchronous lifting and lowering movements.

[0054] like Figure 3 As shown, the cutting head 1021 of the cross-shaped cutter 102 has a symmetrical bevel structure 1022 on both sides. Preferably, the bevel structure 1022 is a 45° bevel.

[0055] The cross-shaped cutter 102 is provided with additional structures for transmitting vibration. Preferably, as follows: Figure 3 As shown, the additional structure for transmitting vibration consists of multiple holes 1023 opened at the bottom of the cross-shaped cutter 102.

[0056] To optimize the crushing process and protect the crucible 2 that carries the material, this invention provides a guide structure near the cutter head 1021 on the cross-shaped cutter 102. Specifically, the guide structure consists of at least two arc-shaped guide grooves 1024 machined on each blade of the cross-shaped cutter 102. These two guide grooves 1024 extend from the top 1020 of the cross-shaped cutter 102 towards the cutter head 1021, and the distance between them gradually narrows, forming a unique arc-shaped channel.

[0057] The core design purpose of these guide grooves 1024 is to provide a pre-defined flow and deformation path for the cross-shaped cutter 102 when it cuts into the blocky material. This arc-shaped, narrowing guide structure aims to guide and quickly release the stress instantly accumulated inside the material by the cross-shaped cutter 102, allowing the stress to dissipate through the guide grooves 1024. This prevents the enormous stress from being completely transferred and acting on the sidewall of the sagger 2, fundamentally eliminating the risk of sagger wall cracking and achieving effective protection for the sagger 2.

[0058] The working process of the calcined powder breaking device 10 is as follows:

[0059] The sagger 2, fully loaded with calcined lumpy material (not shown in the figure), is conveyed through the conveyor line 3 until it stops below the calcined powder breaking device 10. At this time, the cylinder 1000 is started, driving the connected insert blade fixing plate 101, the integrated cross insert blade 102, and the first air vibration device 103 to move down synchronously.

[0060] During this process, the 45° inclined surface structure 1022 of the cross-shaped cutter head 1021 preferentially cuts into the blocky material, efficiently converting the downward pressure into tearing force on the material using the wedge principle. At the same time, the arc-shaped guide groove 1024 set on the cutter head 1021 provides a preset flow path and deformation space for the compressed material, which can quickly guide and release the stress accumulated inside the material, effectively avoiding the concentrated effect of stress on the side wall of the crucible 2, thereby protecting the crucible 2 from damage and achieving low-resistance, high-efficiency mechanical crushing without damaging the tooling.

[0061] Simultaneously, the first air vibration device 103, operating synchronously, generates high-frequency vibration. This vibration is effectively transmitted to the cross blade 102 through the vibration transmission path formed by the blade fixing plate 101. This vibration weakens the internal binding force of the material during crushing, assisting the cross blade 102 in easily cutting in; furthermore, as the cross blade 102 lifts, it thoroughly shakes off any adhering powder, achieving integrated "breaking and cleaning." In addition, multiple holes 1023 on the cross blade 102 serve as additional transmission structures, working in conjunction with the guide groove 1024 to optimize the transmission and distribution of vibration. This ensures efficient, clean, and continuous automated operation of the breaking process, effectively solving the core problems of material adhesion and uneven crushing.

[0062] After crushing is completed, cylinder 1000 drives the cross cutter 102 and the first air vibration device 103 to return to the initial position, waiting for the next working cycle.

[0063] like Figure 1 , Figure 4 as well as Figure 5As shown, the material discharge and dust removal device 11 includes: a clamping device 110, a dust collection box 112, a second air vibration device 113, and a blower mechanism 114. The clamping device 110 is located downstream of the calcined powder breaking device 10, on one side of the conveyor line 3, and is fixed to the ground or a platform where the calcined powder processing equipment 1 is located by a support frame 111. Preferably, the clamping part 1100 of the clamping device 110 (e.g., a robotic arm) is U-shaped, matching the outer contour of the sagger 2.

[0064] In some embodiments, the dust collector 112 includes an inlet 1120 and an outlet 1121. The inlet 1120 is located on the side wall or top of the dust collector 112. In this embodiment, the inlet 1120 is located on the side wall 1122 of the dust collector 112 near the conveyor line 3. The outlet 1121 is located at the bottom of the dust collector 112. A second air vibration device 113 is installed on the outer wall of the outlet 1121. In this embodiment, there are two second air vibration devices 113, which are installed on the outer walls of different sides of the outlet 1121. A blower mechanism 114 is located at the upper edge 1120a of the inlet 1120. Preferably, a plurality of conical air holes 1140 are provided below the blower mechanism 114, and the air outlet direction of the conical air holes 1140 is inclined downward toward the internal space of the inlet 1120.

[0065] The working process of the material discharge dust removal device 11 is as follows:

[0066] After being processed by the calcined powder breaking device 10, the sagger 2 is transported to the downstream station by the conveyor line 3, where it is gripped by the clamping device 110 (such as a U-shaped gripper robot) and inserted into the feed inlet 1120 of the dust collector 112. Subsequently, the clamping device 110 performs a flipping action, pouring the powder in the sagger 2 into the dust collector 112.

[0067] During this material unloading process, the blower mechanism 114, located at the upper edge 1120a of the feed inlet 1120, is simultaneously activated. Multiple conical air holes 1140 below it generate a concentrated, downward-sloping airflow, forming an effective air curtain barrier at the feed inlet 1120. This air curtain suppresses and blows the dust raised during unloading back into the dust collector 112, significantly inhibiting dust escape from the feed inlet 1120 and ensuring a clean external environment. The diameter and taper of the conical air holes 1140 can be designed according to requirements, allowing for flexible adjustment of the airflow intensity. This ensures thorough cleaning while preventing secondary dust diffusion due to excessive force. The blower mechanism 114 is small in size and does not interfere with the unloading operation of the clamping device 110, effectively solving the problem.

[0068] The poured powder eventually collects at the bottom of the dust collector 112 and is discharged through the outlet 1121 into the downstream conveying pipeline (not shown in the figure). The second air vibration device 113, installed on the outer wall of the outlet 1121, can operate periodically or continuously. The vibration it generates is transmitted to the powder indirectly through the outer wall of the outlet 1121, effectively breaking the forces between the powder particles and fundamentally eliminating the "bridging" or adhesion hazards at the outlet 1121, thus ensuring the continuity of material conveying. In addition, the second air vibration device 113 can be connected to the outer wall of the outlet 1121 through an external mounting structure (not shown in the figure), and combined with its inherent compact body structure, it achieves the effects of small size, convenient installation, and no damage to the pipeline.

[0069] In some embodiments, the first air vibration device 103 and the second air vibration device 113 are, for example, piston-type pneumatic vibrators or high-frequency air hammers (not shown in the figure). They operate by introducing compressed air, and the high-frequency vibrations generated are used to assist in crushing, prevent adhesion, and ensure smooth discharge, respectively.

[0070] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims, and all of these forms fall within the protection scope of the present invention.
