Description

A split multifunctional crucible

technical field

The utility model belongs to the technical field of the structural design of split crucibles, in particular to a split multifunctional crucible.

Background technique

When the porous ceramic scaffold is prepared by combining the gel injection molding process and 3D printing technology, it is necessary to degrease, demould and sinter the green body. In this process, due to the high temperature 3D printing mold resin material and the organic monomer of the gel injection molding process The generation of liquid and gas needs to be discharged out of the ceramic support to maintain the biological properties of the ceramic. At present, combustion arks and arc-shaped crucibles are used, and supports of different shapes cannot be fixed in the crucible to discharge the residue.

Contents of the invention

The purpose of this utility model is to provide a split-type multi-functional crucible, through this structure, brackets of different shapes are fixed in the crucible, and the gas and liquid generated by the high temperature of the bracket are discharged to prevent dust and impurities in the furnace from falling into the crucible and contaminating it. The sample is uniformly maintained at the temperature in the crucible.

The technical scheme adopted by the utility model to solve the technical problem is: a split-type multifunctional crucible, including a crucible body, a replaceable pallet, a crucible cover, a supporting platform, a clamping platform, and a sample. The inner wall of the crucible has a raised support platform, on which a replaceable supporting plate is placed, and the length and width of the replaceable supporting plate are respectively one millimeter smaller than the length and width of the inner cavity of the crucible. There are spherical, cylindrical, and cuboid-shaped sink holes on the interchangeable pallet for placing samples of spheres, cylinders, and cuboids. There is a circular drain hole at the bottom of the sink hole. The shape and size of the sink hole on the interchangeable pallet are Different combinations are used to adapt to samples of different shapes and sizes. The joint between the top of the crucible body and the bottom of the crucible cover is a concave-convex fitting structure to avoid the crucible cover slipping off during the process of moving the crucible. The joint surface of the crucible body is concave shape, the joint surface of the crucible lid is convex, and the gap between the concave and convex fitting structures is 0.5mm. Both the crucible body and the crucible cover have raised clamping tables on the outer walls, which can prevent the crucible from slipping when being clamped by the crucible tongs. There are vent holes on the side of the crucible cover.

The utility model has beneficial effects: it can effectively fix samples of different shapes and sizes, discharge liquid and gas generated by high temperature in the crucible, maintain the temperature in the crucible evenly, and prevent dust and impurities in the furnace from falling into the crucible to pollute the samples.

detailed description

In the present utility model, for the convenience of description, the description of the relative positional relationship of each component is described according to the layout of Figure 1 of the specification, such as: up, down, front, back, left, right, inside, outside The positional relationship of etc. is determined according to the direction of the accompanying drawing 1 of the specification.

Embodiment 1, a split-type multi-functional crucible, the inner wall of the crucible body 1 has a raised support platform 4, and a replaceable pallet 2 is placed on the support platform 4, and the length and width of the replaceable pallet 2 are respectively One millimeter smaller than the length and width of the inner cavity of the crucible body 1, the interchangeable supporting plate 2 is provided with counterbores in the shape of spheres, cylinders and cuboids for placing samples 6 of spheres, cylinders and cuboids, and the bottom of the counterbores has a circular The drain hole, the shape and size of the counterbore on the interchangeable supporting plate 2 have different combinations to adapt to samples 6 of different shapes and sizes. To avoid the crucible cover 3 slipping and falling off during the process of moving the crucible, the joint surface of the crucible body 1 is concave, the joint surface of the crucible cover 3 is convex, and the gap between the concave and convex fitting structures is 0.5 mm. The outer wall has a raised clamping platform 5, which can prevent the crucible from slipping when being clamped by the crucible tongs, and the crucible cover 3 has vent holes on the side.

In practical operation, place the crucible body 1 stably on the test bench, select an appropriate replaceable pallet 2 according to the shape, size and quantity of the sample 6 to be heated, and place the selected replaceable pallet 2 on the crucible On the support platform 4 on the inner wall of the body 1, place the sample 6 in the counterbore of the corresponding shape on the replaceable support plate 2, cover the crucible cover 3, and clamp it at the clamping platform 5 outside the crucible body 1 with crucible tongs , put the crucible into the heat treatment furnace. After the heat treatment is completed, take out the crucible smoothly with crucible tongs, and open the crucible cover 3 after the crucible is completely cooled. Residue at the bottom of body 1.

The above shows the structure and usage of the utility model. Those skilled in the art should understand that this utility model is not affected by the above content. The introduction and implementation method of the above structure are only used to illustrate the utility model, and on the premise of not departing from the spirit and scope of the utility model, simple modifications and replacements by those skilled in the art are within the protection scope of the utility model.
