Description

Technical Field

[0001] This utility model relates to the field of high-temperature processing equipment technology, and in particular to a sintering crucible. Background Technology

[0002] A sintering crucible is a container used for sintering materials at high temperatures. During sintering, the material to be sintered is placed inside the crucible, which is then placed in a high-temperature furnace. Through heating, the material undergoes physical and chemical changes within the crucible, and the particles gradually bond together to form a dense structure. Sintering crucibles are generally made of ceramic, graphite, or metallic materials and are widely used in materials science research, metal smelting and casting, the photovoltaic industry, and the electronics industry.

[0003] Currently, most sintering crucibles are single-layer designs, meaning sintered products can only be placed in a single layer inside the crucible, making it impossible to sinter a large number of products at once, and the internal space of the sintering crucible is not fully utilized. Existing technology includes a multi-layer stackable sintering crucible, which allows for stacking multiple layers depending on the number of products, enabling the sintering of a large number of products at once.

[0004] However, when sintering a large number of products, such multi-layer stackable sintering crucibles require placing the sintered products on each layer of sintering crucibles before stacking the multiple layers together. This makes the sintering crucibles prone to tipping over. Furthermore, to facilitate the removal of the sintering crucibles, the crucibles are designed with open sides, which allows dust to easily enter the sintering chamber during the sintering process, affecting the performance of the sintered products. Utility Model Content

[0005] The purpose of this invention is to provide a sintering crucible to solve the problems of multi-layer sintering crucibles being prone to tipping over and dust easily entering the sintering chamber, which affects the performance of sintered products.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A sintering crucible, comprising:

[0008] The box body has a sintering cavity inside and an opening that connects the sintering cavity to the outside along a first direction. A box door is movably connected to one side of the opening of the box body and the box door is used to seal the opening.

[0009] The track assembly includes two opposing guide rails, which are respectively disposed on two opposing inner walls of the sintering cavity along a second direction, and the guide rails extend along the first direction;

[0010] A push-pull panel, wherein rollers are provided on the push-pull panel, and the push-pull panel is rotatably connected to the track assembly through the rollers. A through hole is provided on the push-pull panel, and a handle is provided on the side of the push-pull panel near the box door along the first direction.

[0011] The first direction and the second direction are two mutually perpendicular directions in the horizontal plane.

[0012] In one embodiment, multiple sets of the track assembly are spaced apart along the height direction of the sintering cavity.

[0013] In one embodiment, the two guide rails of the track assembly have guide rail grooves with opposite slot positions, and the rollers are provided on opposite sides of the push-pull plate, and the rollers roll in the guide rail grooves.

[0014] In one embodiment, the guide rail is provided with a detachable limiting structure at one end near the door along the first direction, and the limiting structure is used to limit the push-pull plate.

[0015] In one embodiment, the limiting structure is a limiting pin, which is inserted into the guide rail.

[0016] In one embodiment, the through holes are distributed in a rectangular array on the push-pull plate.

[0017] In one embodiment, the door is hinged to the box body.

[0018] In one embodiment, a door lock is provided on the door, the door lock is located on the side of the door opposite to the hinge, and a corresponding latch is provided on the box body.

[0019] In one embodiment, a sealing ring is provided on the side of the door that contacts the box body.

[0020] In one embodiment, the surface of the push-pull plate is coated with an anti-stick coating.

[0021] The beneficial effects of this utility model are:

[0022] This invention provides a sintering crucible, comprising a box body, a track assembly, and a push-pull plate. The box body contains a sintering cavity and has an opening along a first direction connecting the sintering cavity to the outside. A door is movably connected to one side of the opening for sealing. The sintering crucible is a box-type sealed structure. The track assembly includes two opposing guide rails, which are respectively located on two opposing inner walls of the sintering cavity along a second direction. The guide rails extend along the first direction, which is perpendicular to each other in a horizontal plane. Rollers are provided on the push-pull plate, which is connected to the track assembly via the rollers, reducing frictional resistance between the push-pull plate and the guide rails, resulting in smoother and more stable movement of the push-pull plate. Through holes are provided on the push-pull plate for air circulation, ensuring consistent temperature across all areas of the sintering crucible and preventing the influence of external heating devices on the temperature at different locations within the crucible. A handle is provided on the side of the push-pull plate near the door along the first direction for easy pushing and pulling. This sintering crucible utilizes a track assembly with a sliding plate that is rolled into the sintering chamber, thus dividing the internal space of the sintering chamber into layers. This makes full use of the internal space of the sintering chamber and allows for the simultaneous sintering of a large number of products. At the same time, when taking out or putting in sintered products, it is only necessary to pull out or push in the sliding plate containing the sintered products, which effectively prevents the sintering crucible from tipping over. The box-type sealing structure also prevents dust from entering the sintering chamber and affecting the performance of the sintered products. Attached Figure Description

Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar parts or parts having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0029] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] In the description of this utility model, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] like Figures 1-3 As shown, this utility model provides a sintering crucible, including a box body 1, a track assembly 2, and a push-pull plate 3. The box body 1 has a sintering cavity 11 inside, optionally shaped as a cuboid or cube. The box body 1 also has an opening along a first direction (X direction in the figure) connecting the sintering cavity 11 to the outside. A door 12 is movably connected to one side of the opening of the box body 1, used for sealing and opening the opening. The sintering crucible as a whole has a box-type sealed structure. The track assembly 2 includes two opposing guide rails 21, which are respectively disposed on two opposing inner walls of the sintering cavity 11 along a second direction (Y direction in the figure). The guide rails 21 extend along the first direction, which is a horizontal plane with two mutually perpendicular directions. The push-pull plate 3 is provided with rollers, and the push-pull plate 3 is rolledly connected to the track assembly 2 via the rollers, reducing the frictional resistance between the push-pull plate 3 and the guide rails 21, making the movement of the push-pull plate 3 on the guide rails 21 smoother and more stable. The push-pull plate 3 has through holes for air circulation between the push-pull plates 3, so that the temperature of each area inside the sintering crucible is kept consistent, avoiding the influence of external heating devices on the temperature of different positions inside the sintering crucible. The push-pull plate 3 is provided with a handle on the side near the box door 12 along the first direction, which facilitates the pushing and pulling of the push-pull plate 3 and makes it convenient to take out and put in the sintered products. The material of the handle not only needs to be resistant to high temperature, but also needs to have a low thermal conductivity to reduce heat transfer loss, such as ceramic fiber or enamel.

[0033] The sintering crucible provided by this utility model, by rolling the push-pull plate 3 to the track assembly 2 inside the sintering cavity 11, divides the internal space of the sintering cavity 11 into layers, making full use of the internal space of the sintering cavity 11, and can realize the one-time sintering of a large number of products. At the same time, when taking out or putting in sintered products, it is only necessary to pull out or push in the push-pull plate 3 containing the sintered products, which effectively prevents the sintering crucible from tipping over. The box-type sealing structure also prevents dust from entering the sintering cavity and affecting the performance of the sintered products.

[0034] Specifically, the door 12 is hinged to the body 1, facilitating its opening and closing. Correspondingly, a door lock is provided on the side of the door 12 opposite to the hinge, and a corresponding latch is provided on the body 1. After the sintered product is placed into the sintering crucible, the door 12 and the body 1 can be locked together using the door lock and latch, preventing accidental opening of the door 12 during sintering and ensuring the quality of the sintered product is not affected. In other embodiments, the door lock and latch can be replaced with other locking devices, such as a bolt locking device or a magnetic locking device.

[0035] Furthermore, multiple sets of track assemblies 2 are spaced apart along the height direction of the sintering cavity 11. The spacing between each set of track assemblies 2 can be set differently according to the size of the sintered product. Alternatively, the push-pull plates 3 can be rolled and connected to track assemblies of different heights according to the size of the sintered product, so that the height between the two push-pull plates 3 can adapt to the size of the sintered product, which facilitates the flexible and full utilization of the internal space of the sintering cavity 11.

[0036] Preferably, the two guide rails 21 of the track assembly 2 have guide rail grooves with opposite opening positions. Correspondingly, the rollers of the push-pull plate 3 are arranged on opposite sides. When installing the push-pull plate 3, the rollers are rolled and connected in the guide rail grooves of the guide rail 21 to avoid displacement of the push-pull plate 3 along the height direction of the box 1, which would affect the sintering quality of the sintered product. For example, a detachable limiting structure is provided at the end of the guide rail 21 near the box door 12 along the first direction to limit the push-pull plate 3 and prevent the push-pull plate 3 from shaking on the guide rail 21 in the first direction during the movement of the sintering crucible. When it is necessary to remove the push-pull plate 3 from the sintering chamber 11, the limiting structure can be removed. The limiting structure can be a limiting pin inserted into the guide rail 21 to limit the movement range of the rollers by physical blocking, or other detachable structures with limiting function, which will not be described in detail here.

[0037] Preferably, such as Figure 3As shown, the through holes 31 on the push-pull plate 3 are distributed in a rectangular array, further ensuring the uniformity of airflow between the push-pull plates 3, so that the temperature in each area of ​​the sintering crucible remains consistent, thus improving the sintering quality. Optionally, the shape of the through holes 31 can be circular, square, rhomboid, or elongated, and the spacing between the through holes 31 and the size of the through holes 31 can also be adjusted according to different sintering temperature requirements.

[0038] To further enhance the sealing performance of the sintering crucible, a sealing ring is provided at the contact point between the door 12 and the body 1. The sealing ring is made of high-temperature resistant material, such as high-temperature resistant asbestos or mica. The sealing ring effectively prevents dust from entering the sintering chamber 11 while reducing heat loss from the sintering crucible.

[0039] Furthermore, the surface of the push-pull plate 3 is coated with a high-temperature resistant and non-stick coating. The coating material can be a ceramic-based composite coating. The high-temperature resistant and non-stick coating can effectively prevent the sintering material from sticking to the push-pull plate 3, making it easy to clean and maintain the push-pull plate 3 while ensuring the sintering quality of the sintered product.

[0040] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
