Description

Technical Field

[0001] The utility model belongs to the technical field of high-temperature firing material turnover containers, and in particular relates to a sagger used for firing products. Background Art

[0002] In industrial production and materials science, sagger is an important container used to protect materials from the influence of the external environment under high temperature conditions or in high temperature environments. There are many shapes and materials of saggers, but for the firing of industrial materials, graphite saggers, corundum mullite saggers and metal saggers are relatively widely used to a certain extent. Among them, as for the metal saggers usually made of materials such as stainless steel, nickel-based alloys, and molybdenum, they have the following advantages that are not limited to: good durability, can withstand greater pressure and weight, suitable for long-term repeated use; strong adaptability, good moisture-proof and anti-corrosion properties; good heat transfer, high thermal conductivity, can quickly transfer heat, improve thermal efficiency, and reflect energy saving; easy operation, no additional coating treatment is required during use, which is conducive to reducing scrap rate and maintenance costs; economical and applicable, with a long service life and low comprehensive cost, suitable for large-scale production and long-term use.

[0003] There is no lack of technical information about saggers in the public Chinese patent documents, such as CN210602819U (a new type of sagger), CN210346350U (a new type of sagger), CN222481126U (a wear-resistant sagger), CN102190505B (sagger), CN214250581U (a sagger), CN210268235U (a sagger for sintering furnace), CN207262758U (a sagger) and CN218973206U (a new type of sagger structure), etc.

[0004] A typical example is the "new type of sagger" recommended by CN201116838Y, which is composed of a silicon carbide layer and an aluminum oxide layer. Although this sagger has the advantages recorded in the technical effect column of its specification, due to the different thermal expansion coefficients of silicon carbide and aluminum oxide, it is easy to generate stress at high temperatures, causing cracking or delamination; the interface bonding strength between the two is relatively weak, affecting the overall strength and durability, especially under high temperature or thermal cycle conditions; the production cost is high, the processing is difficult, and due to differences in thermal conductivity, the temperature cooling may be uneven, affecting the use effect.

[0005] A more typical example is the "metal sagger for roasting graphite workpieces" provided by CN218821669U, which is composed of welded steel plates. Through the full text interpretation of the patent, a heat inlet hole is opened in the center of the bottom of the sagger, and a connecting pipe is placed vertically on the top of the heat inlet hole, and a heat conducting pipe is detachably arranged vertically at the center of the inner cavity of the sagger and the bottom end of the heat conducting pipe is threadedly connected to the connecting pipe. Therefore, it has made contributions to the uniformity of temperature distribution in the rectangular cavity. However, as far as the sagger body is concerned, there is a risk of deformation due to insufficient strength in a high temperature environment; as for the sagger cover: there are problems such as thermal deformation, and it is picky about the firing materials because it cannot reflect good air intake and exhaust functions, because many materials such as ceramic materials, glass materials, metal powders, composite materials, refractory materials, electronic materials and catalyst carriers, etc., require reasonable air intake and exhaust during the firing process. For example, during the firing process of ceramic materials, the organic matter, moisture and gas in the materials can be discharged through the air intake and exhaust to avoid bubbles and cracks; for another example, the air intake and exhaust of metal powder during the firing process can improve the density and strength of the sintered body; for another example, the air intake and exhaust of composite materials during the sintering process can avoid internal defects, etc. In addition, the aforementioned CN218821669U has not yet provided inspiration for the manipulator to conveniently grasp the lid, to avoid water accumulation in certain parts of the lid during the cleaning process, and to prevent the lid from being misaligned relative to the sagger body. In view of the above, it is necessary to improve it, and the technical solution to be introduced below is produced in this context. Utility Model Content
