Description

Technical Field

[0001] The utility model relates to the technical field of crucibles, in particular to a crucible for ultra-high temperature sintering. Background Art

[0002] The crucible used for sintering materials is a graphite crucible that can withstand temperatures above 2000°C. The original structure was a cylindrical hollow structure with an open top and a sealed bottom to hold the materials inside. When discharging the materials, it is inconvenient to manually hold the crucible to take them out. In addition, the screw-type end cap is prone to deformation of the body, mouth or end cap after high temperature, resulting in the problem of loose cover. Utility Model Content

[0003] The utility model aims to provide a crucible for ultra-high temperature sintering. The existing crucible is inconvenient to take out by manually holding the crucible when discharging materials. In addition, the screw-type end cover is easy to deform the body or the mouth or the end cover after high temperature, resulting in the problem of loose cover.

[0004] To achieve the above-mentioned purpose, a crucible for ultra-high temperature sintering is provided, comprising: a sintering furnace, a crucible body is placed inside the sintering furnace, an opening is arranged at the upper end of the crucible body, holes are opened on both sides of the crucible body, a material removal clamp is installed inside the opening, an end cover is installed at the upper end of the crucible body, and an end cap is arranged at the upper end of the end cover.

[0005] According to the crucible for ultra-high temperature sintering, the opening is arranged flush, the opening is retracted, and the lower surface of the end cover is flush with the opening.

[0006] According to the ultra-high temperature sintering crucible, the material taking clamp chuck is installed from the inside to the outside.

[0007] The above scheme has the beneficial effects: the utility model has an opening as a retracted inlet and a body mouth as a flush opening, and the end cover is directly placed and covered on the opening, and the end face is covered by the opening flush, so that even if there is deformation, it will not be unable to be screwed or the seal will be loose, and an end cap for opening is arranged on the end cover, which can be opened by holding the end cap and lifting the end cover, and after sintering, the crucible body is clamped with a clamp and taken out of the furnace body, a hole is opened in the side wall of the crucible body for inserting the clamp, and the hole is opened above the end cover, and the way of inserting the clamp head is from the inside to the outside, because the crucible is in the sintering furnace, the distance between the crucible wall and the inner wall of the sintering furnace is very small, and the clamp extending from the inside to the outside does not occupy the space in the sintering furnace.

[0008] Additional aspects and advantages of the present invention will be given in part in the following description, and in part will become apparent from the following description, or will be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0018] Reference Figure 1-5 The utility model embodiment of the ultra-high temperature sintering crucible comprises: a sintering furnace 1, a crucible body 2 is placed inside the sintering furnace 1, an opening 4 is arranged on the upper end of the crucible body 2, openings are opened on both sides of the crucible body 2, a material taking clamp 3 is installed inside the opening, the material taking clamp 3 extends from the inside to the outside and does not occupy the space in the sintering furnace 1, an end cover 5 is installed on the upper end of the crucible body 2, and an end cap 6 is arranged on the upper end of the end cover 5 to facilitate opening the end cover 5.

[0019] The opening 4 is flush with the opening, which is convenient to open. Even if it is deformed, it will not be unable to be screwed or the seal is not tight. The opening 4 is retracted, and the lower surface of the end cover 5 is flush with the opening 4. The chuck of the material taking clamp 3 is installed from the inside to the outside.

[0020] Working principle: When in use, the crucible body 2 is placed inside the sintering furnace 1, covered with the end cover 5, the opening 4 on the lower surface of the end cover 5 is flush, and the end cap 6 is used to open it, which is more convenient when opening. In this way, even if there is deformation, it will not be impossible to screw it or the seal will not be tight. The material removal clamp 3 is inserted from the inside of the opening 4 to the outside to facilitate the removal of the crucible body 2. It is more convenient when operating, and it cannot be from the outside to the inside, because the crucible body 2 is in the sintering furnace 1, and the inner wall of the crucible body 2 is very small from the inner wall of the sintering furnace 1. The material removal clamp 3 extending from the inside to the outside does not occupy the space in the sintering furnace 1.

[0021] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
