Description

Technical Field

[0001] This utility model relates to the field of crucible connecting accessories, and in particular to a detachable graphite crucible connector. Background Technology

[0002] A crucible is a cup-shaped vessel used in laboratories to heat solids at high temperatures. Crucibles come in various models and specifications, and their application is not limited by production scale, batch size, or the type of material being melted. They can be selected arbitrarily, making them highly adaptable and ensuring the purity of the melted material. Crucible connectors are used to connect and fix the crucible, improving its ease of use.

[0003] Previous graphite crucible connectors have the following drawbacks: 1. They are inconvenient for clamping and fixing the crucible body, making installation and disassembly difficult, and they cannot ensure more uniform heating of the raw material or increase the melting rate of the raw material. Therefore, those skilled in the art have provided a detachable graphite crucible connector to solve the problems mentioned in the background art. Utility Model Content

[0004] The main objective of this invention is to provide a detachable graphite crucible connector to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A detachable graphite crucible connector includes a support vertical plate, a crucible body, a positioning circular plate, and a locking cover;

[0007] The positioning circular plate has a limiting hole and is fitted inside the upper end of the crucible body. Supporting vertical plates are installed at equal intervals at the bottom of the positioning circular plate. A locking screw is installed in the middle part of the supporting vertical plate through a screw hole. An arc-shaped clamp is connected to the inner end of the locking screw through a bearing and clamps the outer side of the crucible body. An integrally formed cone is provided at the inner bottom of the crucible body. A locking cover is engaged at the top of the positioning circular plate and located at the upper end of the crucible body.

[0008] As a further embodiment of this utility model: an annular insertion groove is provided on the top of the positioning circular plate and around the limiting hole, and an annular insertion block is provided on the bottom of the locking cover and directly opposite the annular insertion groove.

[0009] As a further improvement of this utility model: the top of the locking cover is provided with a lifting ring, and the bottom of the supporting vertical plate is provided with an integrally formed enlarged foot plate.

[0010] As a further improvement of this utility model: the top two sides of the positioning circular plate are connected to hanging plates by connecting pieces. The hanging plates are provided with hanging holes. When discharging material, the hooks of the two sets of material picking rods are directly hung in the hanging holes of the hanging plates on both sides, and the whole thing is lifted up to facilitate the removal of the crucible.

[0011] As a further improvement of this utility model: the crucible body, the locking cover, the lifting ring and the cone are all made of graphite material. Graphite material has an extremely high melting point and can withstand high temperature environments without melting. Graphite is a material with high thermal conductivity and strong corrosion resistance to both acidic and alkaline solutions.

[0012] As a further improvement of this utility model, the positioning circular plate, the arc-shaped clamping plate, the bearing, the locking screw, and the supporting vertical plate are all made of ceramic material.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By fitting the crucible body into the limiting hole of the positioning circular plate and tightening the locking screws, the arc-shaped clamping plate is moved towards the axis of the crucible body, which facilitates the clamping and fixing of the crucible body, making it easy to install and disassemble. The enlarged foot plate at the bottom of the supporting vertical plate improves the stability of the overall connecting parts placed in the heating furnace cavity. The cone at the bottom of the crucible body facilitates the dispersion of raw materials on the inner wall of the crucible body, making the raw materials more evenly heated and increasing the melting rate of the raw materials.

[0015] 2. When discharging, hang the two sets of material-retrieving rod hooks directly in the hanging holes of the side hanging plates, lift the whole thing up to make it easy to take out the crucible, and use the lifting ring to open the locking cover. When tilting to pick up the material, let the molten liquid flow out along the discharge channel, so that it flows in a concentrated manner and avoids spillage. Attached Figure Description
