Description

Technical Field

[0001] This invention relates to the field of crucible production technology, and in particular to a method and apparatus for producing a high-temperature resistant crucible. Background Technology

[0002] A crucible is a refractory container used in melting machines to smelt molten metals or to carry out chemical reactions. Crucibles are generally wider at the top and narrower at the bottom. They are typically made from refractory materials such as clay, porcelain clay, and quartz, or from metals that are difficult to melt. Crucibles are designed to withstand high temperatures, and different materials are chosen depending on the properties of the material being melted or corroded. Based on the raw materials used, crucibles are mainly classified as cast iron crucibles, platinum crucibles, quartz crucibles, ceramic crucibles, and graphite crucibles. Current crucible production equipment often uses extrusion molding or pressure forming methods. During this process, air bubbles are easily generated in the crucible blank, which can lead to a decrease in quality and an increase in the defect rate after subsequent drying and firing.

Summary of the Invention

[0004] The present invention aims to overcome the shortcomings of existing technologies in terms of poor crucible blank manufacturing quality and high defect rate, and provides a method and apparatus for producing high-temperature resistant crucibles with good crucible blank manufacturing quality and low defect rate.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a method for producing a high-temperature resistant crucible, comprising the following steps.

[0006] S1. Prepare the crucible slurry;

[0007] S2. Crucible blank extrusion manufacturing;

[0008] S3. Drying the crucible blank.

[0009] In crucible production, a slurry, in the form of mud, is first prepared for extruding the crucible blank. This slurry is made from graphite, clay, silica, and wax stone. After the slurry is prepared, the crucible blank is formed by extrusion molding using a molding equipment. Once the blank is formed, it is dried, completing the crucible blank production process.

[0010] The present invention also includes a production apparatus for a high-temperature resistant crucible, used for crucible blank preparation and drying, comprising a forming cavity and an adjusting frame, the adjusting frame being positioned above the forming cavity, the adjusting frame being connected to a retractable extrusion support and a drying support, the extrusion support being connected to a rotatable rotating rod, the rotating rod being positioned inside the forming cavity, a discharge assembly being slidably connected to the rotating rod, a rolling roller being connected to the rear end of the discharge assembly, a swingable shaping roller being provided on the side of the rolling roller, and a drying block being connected to the drying support. The adjusting frame is positioned above the molding cavity. An extrusion support and a drying support are connected to the adjusting frame, both of which are telescopic. The extrusion support is connected to a rotating rod, which can rotate relative to the extrusion support. A sliding discharge assembly is connected to the rotating rod. The discharge assembly is used to extrude the mud-like crucible slurry through the extrusion process. The sliding of the discharge assembly on the rotating rod, in conjunction with the rotation of the rotating rod, allows the discharge assembly to shape the extruded crucible slurry into the form of a crucible blank. Simultaneously, a rolling roller is connected to the rear end of the discharge assembly. The rolling roller compacts the extruded crucible slurry, ensuring molding quality. To avoid air bubbles during molding, which would result in poor blank quality, a shaping roller is installed on the side of the rolling roller. This shaping roller ensures the molding effect of the inner wall of the extruded crucible slurry during molding, thus ensuring the quality of the inner wall molding of the crucible blank and reducing the defect rate. After the extrusion molding of the crucible blank is completed, the extrusion support retracts, driving the rotating rod to move out of the molding cavity. At the same time, the adjusting frame moves the drying support along with the drying block connected to the drying support into the molding cavity to heat the extruded crucible blank and dry it, ensuring the preparation quality and reducing the defect rate.

[0011] Preferably, a rotary motor is connected to the lower end of the extrusion support, and the rotary motor is connected to a rotating rod. The rotary motor is connected between the extrusion chamber and the rotating rod, and the shaft of the rotary motor is connected to the center of the rotating rod. The rotation of the rotary motor can drive the rotating rod to rotate, thereby realizing the extrusion of the crucible blank through rotation and ensuring the forming quality of the crucible blank.

[0012] Preferably, the rotating rod is a telescopic rod, with two centrally symmetrical guide grooves on its two side walls. A telescopic rod is connected to the inner side wall of each guide groove, and the end of the telescopic rod is connected to the discharge assembly. The telescopic rod's length can be adjusted by its extension and retraction. The guide grooves on its side walls allow the telescopic rod to slide within them, enabling the extrusion of the crucible blank. The position of the discharge assembly, adjusted by the telescopic rod, ensures the correct extrusion position of the crucible slurry, guaranteeing the quality of crucible preparation and reducing the defect rate.

[0013] Preferably, the discharge assembly includes a guide block, a mounting block, and a discharge pipe. The guide block is connected to a telescopic rod and has a mounting groove. The mounting block is an L-shaped block, with one end inserted into the mounting groove and hinged to the bottom surface of the groove. The discharge pipe is positioned below the other end of the mounting block and connected to it. The rolling roller is positioned outside the discharge pipe and connected to the mounting block via a bracket. The mounting block has a feed hole that communicates with the discharge pipe and is externally connected to a feeding pump. The guide block is installed in the guide groove, and its side wall is connected to the telescopic rod. An installation groove is provided on the guide block, and one end of the installation block is inserted into the installation groove and hinged to the bottom surface of the installation groove. The extension and retraction of the telescopic rod can drive the guide block to move, thereby driving the installation block to move. A discharge pipe is provided below the installation block. The discharge pipe is a rectangular tube. A feed hole is provided on the installation block and is connected to the discharge pipe. A feeding pump connected to the feed hole can pump the crucible slurry into the feed hole, which is then extruded through the discharge pipe. With the rotation of the rotating rod and the extension and retraction of the telescopic rod, the crucible blank is extruded and formed. At the same time, a rolling roller connected to the installation block through a bracket compacts the extruded crucible slurry to ensure molding quality and reduce the defect rate.

[0014] Preferably, a spring is connected to the upper surface of the mounting groove, and the spring is connected to the mounting block. The spring presses the mounting block down, ensuring that the rolling roller can fully compact the extruded crucible slurry, thus ensuring the forming quality of the crucible blank and reducing the defect rate.

[0015] Preferably, a fixing block is connected to the side wall of the mounting block, and a swing rod groove is provided below the fixing block. A swing rod is connected to the swing rod groove, and a second rotating motor is connected to the swing rod. The lower end of the swing rod is connected to a shaping wheel. A swing rod groove is provided on the fixing block connected to the side wall of the mounting block, and a swing rod is hinged in the swing rod groove. The swing rod is connected to the second rotating motor, which can drive the swing rod to rotate. A shaping wheel is connected to the rotating swing rod. When extruding the bottom surface of the crucible blank, the second rotating motor drives the swing rod to rotate to a horizontal state. When extruding the side wall of the crucible blank, the second rotating motor drives the swing rod to rotate to a vertical state. The rotation of the second rotating motor can adjust the position of the shaping wheel, satisfying the function of the crucible blank at different positions during extrusion molding, ensuring the molding quality of the crucible blank, and reducing the defect rate.

[0016] Preferably, the bottom surface of the adjusting frame is provided with a guide groove, and a slider that can slide along the guide groove is provided in the guide groove. The extrusion bracket and the drying bracket are installed at both ends of the slider. The adjusting frame is provided with a guide groove, and a telescopic cylinder is connected in the guide groove. The telescopic cylinder is connected to the slider, so that the slider can slide in the guide groove. The extrusion bracket and the drying bracket are respectively installed at both ends of the slider, ensuring that the telescopic cylinder can realize the conversion between extrusion and drying by telescopic movement, achieving rapid conversion, thereby ensuring molding quality while reducing the defect rate.

[0017] Preferably, the drying block is frustoconical, and a rotating motor is connected between the drying block and the drying support. The drying block is frustoconical and has the same shape as the inner cavity of the crucible blank. As the drying block extends into the extruded crucible blank, the rotating motor performs secondary shaping on the crucible blank, ensuring the smoothness of the inner wall of the crucible blank and guaranteeing the forming quality of the crucible blank, thus reducing the defect rate.

[0018] Preferably, a heating plate is installed inside the drying block, and a temperature control system is connected to the heating plate. The external temperature control system can control the heating temperature of the heating plate to meet the process requirements, ensuring rapid drying of the crucible blank, ensuring processing efficiency while maintaining molding quality, and reducing the defect rate.

[0019] The beneficial effects of this invention are as follows: the rotating rod drives the discharge pipe to rotate, so that the crucible slurry squeezed out from the discharge pipe forms a crucible blank through rotation. With the compaction and shaping by the rolling roller and the shaping roller, the generation of air bubbles is reduced during the forming of the crucible blank, ensuring the forming quality of the crucible blank. After the crucible blank is formed, it is dried by the rotating drying block that enters the crucible blank, realizing the secondary shaping of the inner wall of the crucible blank, and ensuring drying efficiency and forming quality, thereby reducing the defect rate.

[0033] S1. Prepare the crucible slurry;

[0034] S2. Crucible blank extrusion manufacturing;

[0035] S3. Drying the crucible blank.

[0036] In crucible production, the first step is to prepare a slurry for extruding the crucible blank. This slurry is in a mud-like state. The slurry is made from graphite, clay, silica, and wax stone, with graphite comprising 45-55% of the composition, preferably in crystalline flake or needle-like forms. Refractory clay is used to enhance plasticity, stabilize the physicochemical properties, and provide high refractoriness and good thermal performance. After the slurry is prepared, the crucible blank is extruded using a molding process. Once the blank is formed, it is dried, completing the crucible blank production process.

[0037] A high-temperature resistant crucible production apparatus is used for crucible blank preparation and drying. It includes a forming cavity 1 and an adjusting frame 2. The adjusting frame 2 is positioned above the forming cavity 1. The adjusting frame 2 is connected to a retractable extrusion support 3 and a drying support 4. The extrusion support 3 is connected to a rotatable rotating rod 5, which is placed inside the forming cavity 1. A discharge assembly 6 is slidably connected to the rotating rod 5. A rolling roller 7 is connected to the rear end of the discharge assembly 6. A swingable shaping roller 8 is arranged on the side of the rolling roller 7. A drying block 9 is connected to the drying support 4.

[0038] The lower end of the extrusion support 3 is connected to a rotating motor 30, which is connected to the rotating rod 5.

[0039] The rotating rod 5 is a telescopic rod. Two centrally symmetrical guide grooves 50 are provided on both sides of the rotating rod 5. The inner side wall of the guide groove 50 is connected to a telescopic rod 51. The end of the telescopic rod 51 is connected to the discharge assembly 6.

[0040] The discharge assembly 6 includes a guide block 60, a mounting block 61, and a discharge pipe 62. The guide block 60 is connected to the telescopic rod 51. The guide block 60 is provided with a mounting groove 63. The mounting block 61 is an L-shaped block. One end of the mounting block 61 is inserted into the mounting groove 63 and hinged to the bottom surface of the mounting groove 63. The discharge pipe 62 is placed below the other end of the mounting block 61 and is connected to the mounting block 61. The rolling roller 7 is placed outside the discharge pipe 62 and is connected to the mounting block 61 through a bracket. The mounting block 61 is provided with a feed hole 64, which communicates with the discharge pipe 62. The feed hole 64 is externally connected to a feeding pump.

[0041] A spring 65 is connected to the top surface of the mounting slot 63, and the spring 65 is connected to the mounting block 61.

[0042] A fixing block 66 is connected to the side wall of the mounting block 61. A swing rod groove 67 is provided below the fixing block 66. A swing rod 68 is connected in the swing rod groove 67. A rotating motor 69 is connected to the swing rod 68. The lower end of the swing rod 68 is connected to the shaping wheel 8.

[0043] The bottom surface of the adjustment frame 2 is provided with a guide groove 20, and a slider 21 that can slide along the guide groove is provided in the guide groove 20. The extrusion bracket 3 and the drying bracket 4 are installed at both ends of the slider 21.

[0044] The drying block 9 is frustoconical in shape, and a rotating motor 90 is connected between the drying block 9 and the drying support 4. A heating plate 91 is installed inside the drying block 9, and a temperature control system is connected to the heating plate 91.

[0045] The working principle of this invention is as follows: Figure 1-6As shown, the crucible blank is formed and dried within the forming cavity 1. An adjustment frame 2 is positioned above the forming cavity 1, and a guide groove 20 is provided on the bottom surface of the adjustment frame 2. A slider 21 is positioned within the guide groove 20, and a telescopic cylinder is also installed within the guide groove 20, which drives the slider 21 to slide within the guide groove 20. An extrusion support 3 and a drying support 4 are connected to the slider 21; both the extrusion support 3 and the drying support 4 are telescopic supports. The extrusion support 3 and the drying support 4 are positioned at opposite ends of the slider 21, with a certain distance between them. A rotating motor 30 is positioned below the extrusion support 3, and a rotating rod 5 is connected to the shaft end of the rotating motor 30. Rotation of the rotating motor 30 drives the rotating rod 5 to rotate. The rotating rod 5 is a telescopic rod, and guide grooves 50 are provided on both sides of the rotating rod 5, arranged symmetrically on both sides. A telescopic rod 51 is connected to the inner wall of the guide groove 50, and a guide block 60 is connected to the end of the telescopic rod 51. The guide block 60 is placed inside the guide groove 50 and can slide within the guide groove 50 during the telescopic movement of the telescopic rod 51. A mounting groove 63 is provided on the outer end face of the guide block 60. One end of the mounting block 61 is connected to the bottom surface of the mounting groove 63 by a hinge. A spring 65 is connected inside the mounting groove 63 and is connected to the mounting block 61. The spring 65 acts as a pressure point for the mounting block 61. The mounting block 61 is L-shaped, and a discharge pipe 62 is provided below the other end of the mounting block 61. A feed hole 64 is provided on the mounting block 61 and is connected to the discharge pipe 62. A feed pump is connected to the feed hole 64 to deliver the crucible slurry to the feed hole 64 and discharge it from the discharge pipe 62, completing the extrusion process. A rolling roller 7 connected to a bracket is installed on the mounting block 61. The rolling roller 7 is positioned outside the discharge pipe 62. When the rotating motor 30 rotates and drives the rotating rod 5 to rotate, the rolling roller 7 can compact the crucible slurry discharged from the discharge pipe 62 to ensure molding quality. A fixing block 66 is provided on the side of the mounting block 61. A swing rod 68 groove 67 is provided below the fixing block 66. The swing rod 68 is installed in the swing rod 68 groove 67. The swing rod 68 is driven by the rotating motor 69 to swing. A shaping roller 8 is connected below the swing rod 68. When extruding the bottom of the crucible, the rotating motor 69 rotates to rotate the swing rod 68 to the horizontal direction, without compacting the extruded crucible slurry. When extruding the sidewall of the crucible, the rotating motor 69 rotates the swing rod 68 to the vertical direction. When the crucible slurry is extruded from the discharge pipe 62, the shaping roller 8 will compact and shape the crucible slurry on the side to ensure molding quality.

[0046] After extrusion molding is completed, the extrusion support 3 retracts, taking the rotating rod 5 out of the molding cavity 1. Then, the telescopic cylinder pushes the slider 21, adjusting the drying support 4 above the molding cavity 1 and extending the drying support 4 downwards, causing the drying block 9 to sink into the molding cavity 1. The rotating motor 3 90 rotates, driving the drying block 9 to rotate, performing secondary shaping of the inner wall of the extruded crucible blank. At the same time, a heating plate 91 is installed inside the drying block 9. The temperature of the heating plate 91 is controlled by an external temperature control system to achieve heating and drying of the crucible blank, ensuring molding quality.

[0047] The working steps of this invention are as follows: the telescopic cylinder drives the slider 21 to slide within the guide groove 20, thereby adjusting the extrusion support 3 and the drying support 4. First, the extrusion support 3 is moved above the molding cavity 1, and the length of the rotating rod 5 is adjusted. The extrusion support 3 extends, moving the rotating rod 5 to the bottom of the molding cavity 1. The rotating motor 69 is adjusted, and the swing rod 68 is rotated to a horizontal position. Adjusting the telescopic rod 51 moves the guide block 60 to the center position of the rotating rod 5. The external feeding pump feeds the crucible raw material into the feed hole 64 and extrudes it from the discharge pipe 62. The rotating motor 30 rotates, extruding the crucible slurry onto the bottom surface of the molding cavity 1. At the same time as the rotating motor 30 rotates, the telescopic rod 51 also pushes outward, matching the extension of the rotating rod 5, thereby driving the discharge pipe 62 to gradually move outward. This allows the discharge pipe 62 to achieve the extrusion molding of the bottom surface of the crucible blank through rotation and outward sliding extension. During molding, the roller 7 is set to roll the crucible slurry along with the discharge, ensuring compaction and ensuring molding quality. After the crucible bottom is formed, the rotating rod 5 continues to rotate, and the mounting block 61 is placed on the outermost side of the rotating rod 5. This allows the discharge pipe 62 to form the sidewall of the crucible blank under the rotation of the rotating rod 5. After the sidewall of the crucible blank has been formed to a certain height, the rotating motor 69 rotates, adjusting the swing rod 68 to a vertical position. This allows the shaping wheel 8 to shape the sidewall of the extruded crucible blank along with the rotation of the rotating rod 5, achieving lateral compaction and ensuring that the crucible slurry extruded from the discharge port is compacted, thus guaranteeing the forming quality. Because the crucible blank is open-shaped, during the sidewall extrusion forming, the extrusion support 3 gradually retracts upwards, while the rotating rod 5 extends as the radius of the crucible blank increases at different positions to meet the forming shape requirements of the crucible blank and ensure the forming quality of the crucible blank.

[0048] After the crucible blank is extruded, the telescopic cylinder pushes the slider 21 to move, removing the extrusion support 3 from above the molding cavity 1 and adjusting the drying support 4 above the molding cavity 1. At the same time, the drying support 4 extends downward, causing the drying block 9 to sink. A rotary motor 3 90 is connected to the lower end of the drying support 4. The rotation of the rotary motor 3 90 can drive the drying block 9 to rotate. The rotation of the drying block 9 can shape the inner wall of the crucible blank. At the same time, the heating plate 91 inside the drying block 9 is temperature controlled by an external temperature control system to ensure that the heating temperature is suitable for drying the crucible blank and ensuring the molding quality.

[0049] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
