Description

Technical Field

[0001] The utility model relates to a graphite crucible sagger loading and firing technology, in particular to a double sagger for graphite crucible roasting. Background Art

[0002] The production process of graphite crucible processing is as follows: pretreatment of raw materials (pre-crushing, calcining or drying); crushing, screening and grading of raw materials; batching of granular and powdered raw materials; adding binder and mixing with binder; forming of mixed paste; roasting of semi-finished products after forming (or firing; roasting of artificial graphite crucibles; graphitization of semi-finished products; impregnation operation to improve product density and strength; mechanical processing of products, etc.

[0003] The formed graphite crucible is usually placed in a sagger for roasting. The sagger currently used is generally a cylindrical container with a graphite crucible (such as Figure 1 and Figure 2 As shown in the figure, during the operation of loading and unloading the kiln, only one can be loaded at a time, which is inefficient, and a single sagger is cylindrical, which is difficult to realize in terms of automatic transportation and loading, affecting work efficiency. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the shortcomings of the prior art and provide a double sagger for baking a graphite crucible which has reasonable design, high working efficiency and is easy to realize mechanized operation.

[0005] The technical solution of the utility model is:

[0006] A double sagger for graphite crucible roasting comprises two saggers, wherein two saggers are arranged in parallel and at least two connecting plates are arranged between the two saggers, each sagger contains at least two graphite crucibles, and fillers are respectively filled between the graphite crucibles and the saggers and between adjacent graphite crucibles.

[0007] Furthermore, both ends of the connecting plate are arc-shaped surfaces, which can match the outer circumferential surface of the sagger and are fixed together by welding.

[0008] Furthermore: the sagger is a barrel-shaped structure, made of stainless steel, and the filler is quartz sand, river sand or other materials.

[0009] The beneficial effects of the utility model are:

[0010] 1. The utility model is composed of two circular saggers assembled together for use, and a hanging point is added in the middle of the sagger. The hanging point is also used as a positioning point for the crucible equipment, which can realize mechanical operation and reduce labor intensity.

[0011] 2. The height of a single sagger of the utility model is doubled compared with the original sagger, and the capacity is large. Four graphite crucibles can be loaded at one time, and the roasting efficiency is high, and the loading and unloading efficiency is also high.

[0012] 3. Two connecting plates are arranged between the two saggers of the utility model, which improves the overall strength and prolongs the service life. In addition, fillers are filled between the two graphite crucibles in each sagger, which ensures the roasting effect and prevents bumps and scratches.

[0013] 4. The utility model has reasonable design, high working efficiency and is easy to realize mechanized operation. The graphite steel pot will not be skewed, which saves time and effort and has good economic benefits after promotion. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Example 1: See Figure 3 -- Figure 4 , In the figure, 1-sagger, 2-filler, 3-graphite crucible, 4-connecting plate.

[0019] A double sagger for graphite crucible roasting comprises a sagger 1, wherein: two saggers 1 are arranged in parallel, and at least two connecting plates 4 (two in the figure, and three or four, determined according to needs) are arranged between the two saggers 1, at least two graphite crucibles 3 (two in the figure) are arranged in each sagger 1, and fillers 2 are respectively filled between the graphite crucibles 3 and the saggers 1 and between adjacent graphite crucibles 3.

[0020] Optimal solution: Both ends of the connecting plate 4 are arc-shaped surfaces, which can match the outer circumferential surface of the sagger 1, and are fixed together by welding.

[0021] Optimal solution: the sagger 1 is a barrel-shaped structure made of stainless steel, and the filler 2 is made of quartz sand, river sand or other materials.

[0022] When in use, first fill some filler 2 at the bottom of the sagger 1, then place a graphite crucible 3 into it, and fill the gap between the graphite crucible 3 and the sagger 1 with filler 2. If necessary, tools can be used to properly tamp the filler 2. When the filler 2 submerges the sagger 1 below, place the second sagger 1, and finally fill the gap with filler to complete the loading of the graphite crucible 3. Use the lifting equipment to hang the connecting plate 4, lift the entire sagger 1 to the desired position, and complete a working cycle.

[0023] Embodiment 2: This embodiment is basically the same as Embodiment 1, and the similarities are not repeated here. The difference is that: the graphite crucible 3 is covered with a filler 2 of more than 350 mm.

[0024] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Any simple modification made according to the technical essence of the utility model still falls within the scope of the technical solution of the utility model.
