Description

Technical Field

[0001] This invention belongs to the field of crucible forming technology, specifically relating to a ceramic crucible forming equipment and forming method. Background Technology

[0002] Currently, ceramic crucibles possess excellent properties such as high temperature resistance and corrosion resistance, and are widely used in smelting and calcination processes in metallurgy, chemical industry, and materials science. At present, the forming process of ceramic crucibles mostly adopts slip casting or pressing.

[0003] During the injection and pressing of ceramic slurry, air bubbles inevitably get mixed in or remain inside the slurry. Existing equipment usually uses simple mechanical vibration or static vacuuming to remove air bubbles. For slurries with high viscosity, this method of air removal is inefficient and incomplete. Residual air bubbles can cause pores or loose structure inside the crucible after sintering, which seriously affects the mechanical strength, high temperature resistance and service life of the crucible.

[0011] Preferably, the drainage mechanism includes a water outlet pipe 1 and a bracket 2. The water outlet pipe 1 is installed and connected inside the cavity 1.

The output shaft of the drive motor is detachably connected to the lower mold housing, and the output shaft of the drive motor is eccentrically positioned relative to the center point of the lower mold housing.

[0014] A method for forming a ceramic crucible, comprising the following steps using the aforementioned ceramic crucible forming equipment: Step 1: The staff puts a measured amount of slurry into the lower mold device, and the upper mold device and the lower mold device work together; Step 2: Use an eccentric rotating device to remove air bubbles from the slurry, so that the slurry is formed into a crucible blank.

[0015] Compared with the prior art, the advantages and positive effects of the present invention are as follows: (1) Existing molding equipment usually uses simple machine vibration or static vacuuming to exhaust air. However, this application has an eccentric rotating device installed in the base, and the lower mold device is detachably connected to the top of the eccentric rotating device. The lower mold device rotates eccentrically during the molding process. The powerful centrifugal force and the eccentric vibration force work together to force the air bubbles inside the slurry to be discharged quickly. At the same time, under the action of centrifugal force, the slurry can adhere more evenly and densely to the inner wall of the lower mold shell and squeeze out excess water, which effectively improves the strength, density and yield of the ceramic crucible blank. (2) A rubber sleeve is installed inside the upper mold shell. The rubber sleeve is inflated with air in advance to expand it and tightly block the micropores on the outer periphery of the upper mold shell, effectively preventing the slurry and water from flowing back into the upper mold shell. When demolding is required, the rubber sleeve is evacuated and contracted to allow air passage, thereby extending the service life of the upper mold and reducing maintenance and cleaning costs. (3) An arc-shaped overflow transition ring is provided above the inner shell of the lower mold, and a collection plate with a collection groove is installed on the outer periphery of the lower mold shell. During the process of the upper mold pressing and squeezing the slurry and rotating eccentrically, the excess slurry can flow into the collection groove of the collection plate along the overflow transition ring under the action of centrifugal force and squeezing force, thus avoiding the waste slurry splashing and polluting everywhere. (4) After molding and dehydration, air is injected into the gap between the upper mold shell and the lower mold inner shell by an air compressor. The gas is blown out evenly through the micro-hole one of the upper mold and the micro-hole two of the lower mold, forming an air cushion between the crucible blank and the mold, so that the crucible blank can be separated from the upper and lower molds smoothly and evenly. This avoids the problem of blank deformation or damage caused by traditional mechanical forced demolding, and greatly ensures the integrity of demolding. (5) The continuous oscillation force generated by the eccentric rotation can effectively break the surface tension of the bubbles, causing the tiny bubbles to aggregate and grow larger. Then, under the action of centrifugal force, they are quickly squeezed out of the material. It can also form extremely complex turbulence and secondary eddies, which can effectively prevent substances with different specific gravities from stratifying or settling and promote the uniform mixing of the slurry.

[0041] A method for forming a ceramic crucible includes the following steps: Step 1: The staff puts a certain amount of slurry into the lower mold device 2, and the upper mold device and the lower mold device 2 cooperate. Step 2: Use an eccentric rotating device to remove air bubbles from the slurry, so that the slurry is formed into a crucible blank.

[0042] In this invention, step one includes: opening cylinder four 25, which pushes connecting plate two 26 to connect air inlet pipe two 16 with inflation pipe one 27, i.e., opening the female end of automatic connector one to connect air inlet pipe two 16 and inflation pipe one 27; closing cylinder four 25; turning on air compressor 15, pump three 23 and valve three 28 to inflate rubber sleeve 32, causing it to expand inside the upper mold shell; the expanded rubber sleeve 32 tightly blocks the micropores one on the outer periphery of the upper mold shell; closing valve three 28; and the operator injects a pre-mixed quantitative ceramic slurry into the forming cavity of the lower mold inner shell 33 of the lower mold device 2; closing the female end of automatic connector one to separate air inlet pipe two 16 and inflation pipe one 27; opening cylinder one 6, which pushes adsorption component one and drives the upper mold 5 downward; adsorption component one in the ceramic crucible... Before production, the upper mold 5 is activated to hold the slurry, allowing it to enter the slurry in the lower mold inner shell 33. The slurry is squeezed to initially fill the gap between the upper mold outer shell and the lower mold inner shell 33. Excess slurry flows into the collection groove along the arc-shaped overflow transition ring above the lower mold inner shell 33. The first adsorption component is closed, and it detaches from the upper mold outer shell. The first cylinder 6 drives the first adsorption component back to its initial position. The second cylinder 9 is activated, and the second adsorption component drives the cover plate 7 to press down. The second adsorption component has already activated to hold the cover plate 7 before the ceramic crucible is produced. The through hole of the cover plate 7 is set outside the upper mold outer shell. At the same time, the protrusion 8 below the cover plate 7 is embedded in the groove 1 of the collection plate 3, completing the closure of the entire molding cavity. The second adsorption component is closed, and it detaches from the cover plate 7. The second cylinder 9 drives the second adsorption component back to its initial position.

[0043] In this invention, step two includes: turning on drive motor one. Since the output shaft 24 of drive motor one is eccentrically set with the lower mold shell 34, the lower mold device 2 begins to perform eccentric centrifugal rotation. The strong centrifugal force and eccentric oscillation force force the air bubbles inside the slurry to be quickly discharged. Under the action of centrifugal force, the slurry is uniformly and densely attached to the inner wall of the lower mold inner shell 33. Excess slurry will be thrown out along the arc-shaped overflow transition ring above the lower mold inner shell 33 and flow directly into the collection groove of the collection plate 3. The water of the blank near the lower mold inner shell 33 is squeezed out through the micropores of the lower mold inner shell 33 under the action of centrifugal force and enters the cavity one between the lower mold inner shell 33 and the lower mold shell 34. The water falls on the inclined plate 35 and gathers to the side of the water outlet pipe. After a period of time, Turn off drive motor one, open cylinder three 12, so that drain pipe 11 contacts water outlet pipe one, and air inlet pipe three contacts air inlet pipe one 14. Open the female end of automatic connector three, and drain pipe 11 and water outlet pipe one are connected. Close cylinder three 12, open valve five and pump four, so that water in cavity one is discharged through drain pipe 11. After a period of time, close valve five and pump four, open cylinder four 25, cylinder four 25 pushes connecting plate two 26, so that air inlet pipe two 16 is connected to air inlet pipe one 27, and air inlet pipe two 29 is connected to air inlet pipe three 17. That is, open the female end of automatic connector one to connect air inlet pipe two 16 and air inlet pipe one 27. Close cylinder four 25, open pump one 19, valve three 28 and valve two 22, so that gas in rubber sleeve 32 is discharged through exhaust. After the first tube 18 is discharged, and after a period of time, pump 19, valve 3 28, and valve 2 22 are closed, and the female connector of automatic connector 2 is opened to connect inflation tube 2 29 and air inlet tube 3 17. Air compressor 15, pump 3 23, and valve 4 30 are turned on to inflate the rubber sleeve 32 and the upper mold shell. The gas enters between the crucible blank and the upper mold shell through micro-hole 1, causing the crucible blank to separate from the upper mold shell. After a period of time, valve 4 30 is closed, and the female connector of automatic connector 4 is opened to connect inflation tube 3 and air inlet tube 1 14. Valve 6, valve 1 21, and pump 2 20 are turned on, and air compressor 15 inflates the lower mold shell 34 and the lower mold inner shell 33. The gas enters between the inner side of the lower mold inner shell 33 and the crucible blank through micro-hole 2. The crucible blank is separated from the lower mold inner shell 33. Valves 6, 1, 21, 20, 15, and 3, and the female connectors of automatic connectors 4, 3, 1, and 2 are closed. Cylinders 4, 25, and 3, 12 are opened, causing the drain pipe 11 and inflation pipe 1, 27 to return to their initial positions. Cylinder 2, 9, and adsorption component 2 are opened, adsorbing and fixing the cover plate 7. Cylinder 2, 9, drives the cover plate 7 back to its initial position. Cylinder 2, 9, is closed. Cylinder 1, 6, and adsorption component 1 are opened, adsorbing and fixing the upper mold 5. Cylinder 1, 6, drives the upper mold 5 back to its initial position. The ceramic crucible blank has reached a certain strength, and the operator can then remove the formed crucible blank from the lower mold inner shell 33.

[0044] In this invention, the collection tank above the collection plate 3 can be cleaned periodically according to the amount of overflowing slurry and the solidification of the slurry in the collection tank.

[0045] In this invention, the above process can be automatically controlled by a controller.
