Description

Technical Field

[0001] The utility model relates to the technical field of firing ceramics, in particular to a bowl loading and bowl inverting structure for ceramic magnetic powder. Background Art

[0002] At present, the research on positive electrode materials of sodium ion batteries mainly focuses on three types: layered transition metal oxides, Prussian blue analogs and polyanion compounds. Polyanion materials have become one of the ideal choices for positive electrode materials of sodium ion batteries due to their low cost, green environmental protection, good structural stability and long cycle life.

[0003] In the process of firing ceramics, saggers are often used as firing containers to prevent gases and harmful substances from damaging and contaminating the body and glaze. Figure 1 and Figure 2 As shown, when the polyanion material of the sodium ion battery is fired in the sagger 1, the conventional loading method is to directly pour the material 2 into the sagger 1. During sintering, the material 2 (polyanion material) is easy to compact and expand in volume during the sintering process, which will eventually cause the sintered product to be similar to a high-hardness brick, and the fired ceramic body is easy to stick to the sagger, and automatic material pouring and crushing cannot be achieved during large-scale mass production.

[0004] Therefore, it is urgent to provide a novel ceramic powder filling and inverting bowl structure. Utility Model Content

[0005] The technical problem to be solved by the utility model is: in order to overcome the shortcomings of the prior art that materials are easy to be hardened and difficult to be broken, the utility model provides a bowl loading and bowl inverting structure for ceramic magnetic powder.

[0006] The utility model adopts the following technical solution to solve the technical problem: a ceramic powder loading and unloading structure, comprising a sagger, a profiling tool and a discharging tool, wherein the sagger is provided with a cavity, the profiling tool can be placed inside the cavity, one or more cavities are provided on the body of the profiling tool, the cavities are used to fill the ceramic powder to be sintered, and the ceramic powder is formed by shaping the cavities, with gaps between adjacent ceramic powders; the discharging tool can be embedded in the gaps between the ceramic powders, and the sintered ceramic powder is crushed by rotation.

[0007] When feeding, a contouring tool is added to leave gaps between the materials; when unloading, a discharging tool with the same shape as the contouring tool is used to crush the materials, thereby solving the problems of agglomeration and crushing.

[0008] Furthermore, the shape of the cavity can be designed according to the requirements, and can be designed as a circular or other shaped opening cavity. Preferably, the cavity is an inverted cone. The conical cavity is convenient for demoulding after molding, and is further preferably a conical cavity without edges and corners, so that the integrity of the ceramic powder can be ensured during demoulding.

[0009] More preferably, the taper of the cavity is 10%-70%.

[0010] Take a frustum as an example: The calculation method of taper: The taper of a frustum is the ratio of the difference between the base radius and the top radius to the height of the frustum, expressed as a percentage. The calculation formula is, taper = (base radius - top radius) / frustum height * 100%.

[0011] Furthermore, the profiling tool is made of plastic or ceramic material. Avoid using metal to avoid introducing other metal impurities, and plastic products are the best.

[0012] Furthermore, the unloading tool comprises a rotating shaft and a paddle, wherein the paddle is fixed to the lower end of the rotating shaft, and the upper end of the rotating shaft is used to connect the driving device, and the paddle is provided with a plurality of blades, the number of blades is the same as the number of cavities, and when the unloading tool is installed in the sagger, each blade can be embedded between adjacent ceramic powders. The upper end of the unloading tool is an automated equipment connection port, and the lower end is a rotating paddle for crushing the material.

[0013] Furthermore, a contoured cambered surface is provided on the front side of the blade, and the shape of the contoured cambered surface matches the outer shape of the cavity, so as to enclose the ceramic powder after the cavity is shaped.

[0014] Furthermore, in order to achieve reliable connection with the driving device, the upper end of the rotating shaft is cut along the axial direction to form at least one anti-rotation surface.

[0015] Preferably, there are two anti-rotation surfaces, which are symmetrically arranged along the radial direction.

[0016] Preferably, the unloading tool is made of ceramic material.

[0017] More preferably, the ceramic material is zirconia ceramic.

[0018] Furthermore, the blade surface has sharp protrusions to facilitate crushing of sintered hard materials.

[0019] Furthermore, the shape of the unloading tool matches the shape of the gap, and the outer dimensions are smaller than the dimensions of the gap. The dimensions of the unloading tool are slightly smaller than the portion of the contour tool not filled with powder, so as to ensure that the unloading tool can be inserted into the gap.

[0020] The beneficial effects of the utility model are as follows: the utility model provides a ceramic powder loading and unloading structure, which, when feeding, adds a profiling tool to leave gaps between materials to avoid forming large lumps during sintering and being difficult to break in the later stage; when breaking, the material is pried and stirred in the gap through the unloading tool to realize automatic unloading and improve work efficiency; and the gap generated by the profiling tool matches the structure of the unloading tool, which can make the front and rear process processes more closely connected and simplify the process.

[0031] The utility model is now described in further detail in conjunction with the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic tooling of the utility model in a schematic manner, so they only show the components related to the utility model, and the directions and references (for example, up, down, left, right, etc.) can only be used to help describe the features in the drawings. Therefore, the following specific embodiments are not adopted in a restrictive sense, and the scope of the subject matter for which protection is sought is limited only by the attached claims and their equivalents.

[0032] like Figure 3-Figure 6 As shown, a ceramic powder filling and unloading structure of the utility model comprises a sagger 1, a profiling tool 3 and a discharging tool 4, wherein the sagger 1 is provided with a cavity, the profiling tool 3 can be placed inside the cavity, and the body of the profiling tool 3 is provided with one or more cavities 31, the cavities 31 are inverted cones, the cavities 31 are used to fill the ceramic powder to be sintered, and the ceramic powder 5 is formed by shaping the cavities 31, and gaps are left between adjacent ceramic powders 5; the discharging tool 4 can be embedded in the gaps between the ceramic powders 5, and the sintered ceramic powders 5 are crushed by rotating. The shape of the discharging tool 4 is similar to the part of the profiling tool 3 that is not filled with powder, and the size of the discharging tool is slightly smaller than the part of the profiling tool that is not filled with powder, so that the discharging tool 4 can be conveniently embedded in the gaps between the ceramic powders 5. The cavity 31 is inverted cone, and the taper of the cavity 31 is 10%-70%. The profiling tool 3 is made of plastic or ceramic material, and metal is avoided to avoid introducing other metal impurities. Plastic products are the best.

[0033] like Figure 7-Figure 8 As shown, the unloading tool 4 includes a rotating shaft 41 and a paddle 42, wherein the paddle 42 is fixed to the lower end of the rotating shaft 41, and the upper end of the rotating shaft 41 is used to connect the driving device, and the paddle 42 is provided with a plurality of blades 43, the number of blades 43 is the same as the number of cavities 31, and when the unloading tool 4 is placed in the sagger 1, each blade 43 can be embedded between adjacent ceramic powders 5. In this embodiment, preferably, there are four blades 43, and the front side of the blade 43 is provided with a contoured camber 44, the shape of which matches the shape of the cavity 31, and can enclose the ceramic powder 5 after the cavity 31 is shaped. The surface of the blade 43 has a pointed protrusion, which can be set on the entire surface of the paddle. In this embodiment, it is preferably set on the contoured camber 44 to facilitate the crushing of hard materials after sintering. Since there are pointed protrusions on the surface of the blade 42, the shape of the unloading fixture 4 matches the shape of the gap, and the outer dimensions are smaller than the dimensions of the gap, so that the blade 42 can be smoothly inserted into the gap. The upper end of the rotating shaft 41 is cut along the axial direction to form at least one anti-rotation surface 45. There are two anti-rotation surfaces 45, which are symmetrically arranged along the radial direction. The unloading fixture 4 is made of ceramic material, preferably zirconia ceramic.

[0034] Working principle:

[0035] First, the profiling tool 3 is loaded into the empty sagger 1, and then the ceramic powder 5 to be sintered is added into the cavity 31 of the profiling tool 3. After the material is added, the powder can be appropriately pressurized to compact the powder, or it can be unpressurized. Subsequently, the profiling tool 3 is removed, and the ceramic powder 5 is formed by shaping the cavity 31, and the sagger 1 containing the shaped ceramic powder 5 is sent to the kiln for sintering.

[0036] After the powder is sintered, the automatic driving device drives the paddle 42 of the unloading tool 4 into the sagger 1, and the paddle 42 is embedded in the gap. The unloading tool 4 is rotated appropriately, and the paddle 42 moves the sintered ceramic powder 5, and the bottom surface of the ceramic powder 5 will be separated from the sagger 1, and the ceramic powder 5 is initially crushed by the rotation of the blade 42 and the pointed protrusion on the blade 42. Then, the powder is poured out of the sagger 1 and sent to the subsequent crushing and screening process.

[0037] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without departing from the scope of the utility model through the above description. The technical scope of this utility model is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
