Description

Technical Field

[0001] This utility model belongs to the field of crucible roasting technology, and specifically relates to a crucible roasting device. Background Technology

[0002] Graphite crucibles are a type of crucible made from graphite, clay, silica, and wax stone. They are primarily used for smelting non-ferrous metals and their alloys, such as copper, brass, gold, silver, zinc, and lead. These crucibles are characterized by high temperature resistance, strong thermal conductivity, good corrosion resistance, and long service life. The production process involves mixing the raw materials, pressing the mixture into shape using a mold, and then subjecting the pressed crucibles to subsequent firing and graphitization processes. Before firing, the crucibles need to be supported to prevent tilting or collapse, especially when firing multiple pieces, as collapse can cause them to stick together. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a crucible roasting device with a simple structure and convenient and practical design. The height of the support plate can be adjusted by adjusting the rod, so that the support plate can be adjusted according to the height of the crucible blank. At the same time, the filler is positioned by limiting ring and annular ring, so as to achieve the purpose of adjusting the height of the support point and supporting and positioning the crucible by the filler.

[0004] A crucible roasting apparatus includes a roasting furnace moving base, high-alumina bricks for lower support, a material plate, side support plates, roasting fixing devices, and a crucible blank. Two side support plates are symmetrically arranged on the roasting furnace moving base. Several material plates are arranged from top to bottom and connected between the two side support plates. Several high-alumina bricks for lower support are connected between the material plate near the roasting furnace moving base and the roasting furnace moving base. Several roasting fixing devices are arranged on the material plate, and the crucible blank is arranged on the roasting fixing devices. The roasting fixing device includes a partition plate, high-alumina bricks for lower support, and a gas guide pipe. The partition plate has a transition hole. One end of the gas guide pipe passes through the transition hole and through the material plate, and the other end is located inside the crucible blank. Several high-alumina bricks for lower support are connected between the partition plate and the material plate and are arranged around the gas guide pipe.

Detailed Implementation

[0017] The embodiments of this utility model are further described below with reference to the accompanying drawings.

[0018] Example 1

[0019] like Figures 1 to 3As shown; a crucible roasting apparatus includes a roasting furnace movable base 1, high-alumina bricks 2 for lower support, material plates 3, side support plates 4, roasting fixing devices 6, and crucible blanks 7. Two side support plates 4 are symmetrically arranged on the roasting furnace movable base 1. Several material plates 3 are arranged from top to bottom and connected between the two side support plates 4. Several high-alumina bricks 2 for lower support are connected between the material plates 3 near the roasting furnace movable base 1 and the roasting furnace movable base 1. Several roasting fixing devices 6 are arranged on the material plates 3, and the crucible blanks 7 are arranged on the roasting fixing devices 6. The roasting fixing device 6 includes a partition plate 61, high-alumina bricks 63 for lower support, and a gas guide pipe 65. The partition plate 61 has openings for... The transition hole 64 is provided. One end of the gas guide pipe 65 passes through the transition hole 64 and the material plate 3, and the other end is placed inside the crucible blank 7. Several high-alumina bricks 63 are connected between the partition plate 61 and the material plate 3 and are arranged around the gas guide pipe 65. The calcination fixing device 6 also includes an adjusting rod 66 and a support plate 67. The support plate 67 is connected to the gas guide pipe 65 through several adjusting rods 66. A limiting ring 69 is provided on the support plate 67, and filler 68 is provided inside the limiting ring 69. An annular ring 62 is provided on the partition plate 61, and filler 68 is provided between the annular ring 62 and the crucible blank 7. Heat conduction holes 5 are provided on the material plate 3. The high-alumina bricks 63 are inclined.

[0020] Adjusting the height of the support plate 67 by adjusting the depth of the crucible blank 7 using the depth adjustment rod 66, while maintaining an overflow gap between the limiting ring 69 and the bottom of the crucible blank 7 (controlled between 1mm and 5mm), filler 68 is introduced into the limiting ring 69. The filler 68 overflows the limiting ring 69, causing the bottom of the inverted crucible blank 7 to press and flatten the overflowing filler 68. The flattened filler 68 is then discharged through the overflow gap, supporting the bottom of the inverted crucible blank 7. The crucible blank 7 is then rotated until its opening contacts the partition plate 61, and the filler 68 is then introduced into the annular ring 62, allowing the filler 68 to support the bottom of the crucible blank. The outer wall of the 7-mouth section is supported and limited to prevent deformation during firing. Before firing the crucible blank 7, it needs to be preheated. The high-temperature gas generated by the combustion gas impacts the two material plates 3, making the gas pressure between the two material plates 3 higher than other areas. The high-temperature gas rises due to its flow and the higher gas pressure makes it easy for the hot gas to enter the crucible blank 7 through the gas guide pipe 65. At the same time, the hot gas is introduced into the crucible blank 7 through the transition hole 64, so that the inside and outside of the crucible blank 7 are preheated quickly. This improves the preheating effect inside the crucible blank 7, ensuring that the crucible will not collapse during firing when it is upside down, and ensuring that the crucible blank 7 will not collapse or crack during firing.
