Description

Technical Field

[0001] This utility model relates to the field of pressure furnace technology, specifically to an automatic pressure furnace for glass and ceramics. Background Technology

[0002] Glass-ceramics are inorganic non-metallic materials produced through a controlled crystallization process, combining the amorphous structure of glass with the crystalline structure of ceramics. Their microstructure consists of uniformly distributed nano- to micron-sized crystals embedded within a residual glass matrix. This unique combination endows them with excellent physicochemical properties. The process requires melting raw materials such as silicates and alumina into molten glass at high temperatures, followed by pressure molding in a pressure furnace. However, existing pressure furnaces mostly cool the material within the mold by blowing air or spraying water onto the mold to accelerate heat dissipation. Spraying water for cooling easily leads to water waste, and the water used for cooling cannot be fully recycled. Summary of the Invention

[0003] (1) Technical problems to be solved

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic pressure furnace for glass and ceramics.

When the electric fan rotates, it can also drive the conveying blades inside the conveying cylinder to rotate in conjunction with the movable plate and the movable groove. This allows the water source to circulate and cool the cooling pipe, the first circulation pipe, and the second circulation pipe as the electric fan continues to rotate. The structure is simple and easy to operate. It can perform air cooling and water cooling at the same time, which can accelerate the cooling speed of the mold and the material. It can also drive the water source to circulate when blowing air, which can further improve the cooling speed during pressure molding and will not waste the water source used for cooling.

Detailed Implementation

[0025] This specific embodiment is an automatic pressure furnace for glass and ceramics, and its structural schematic diagram is shown below. Figure 1-6 As shown, an automatic glass and ceramic pressurizing furnace includes a base 1, a furnace cover 2 installed on the top of the base 1, a pressurizing machine body 3 installed inside the furnace cover 2, ventilation holes at both ends inside the furnace cover 2, and intercepting nets installed inside the ventilation holes. A placement mold 4 is installed on the top of the base 1 corresponding to the pressurizing machine body 3. A circulating cooling mechanism is installed on the placement mold 4 and the base 1. The circulating cooling mechanism includes an air inlet component, a linkage circulation component, and a storage component. The air inlet component is used to cooperate with and drive the linkage circulation component to cool the material in the placement mold 4. The storage component is used to add and store water. When in use, the device can use the air inlet component to cooperate with and drive the linkage circulation component to cool the material in the placement mold 4, and the storage component to add and store water. The structure is simple and easy to operate. It can perform air cooling and water cooling simultaneously, which can accelerate the cooling speed of the placement mold 4 and the material. It can also drive the water source to circulate when blowing air, which can further improve the cooling speed during pressurization and molding, and will not waste the water source used for cooling.

[0026] In this embodiment, the air intake component includes an annular groove inside the placement mold 4. Both sides of the outer wall of the placement mold 4 have mating holes. A connecting pipe 5 is slidably connected to the inner side of the mating hole. A blower 6 is installed at one end of the connecting pipe 5, and an electric fan 7 is installed at one end of the inner wall of the blower 6. Multiple sets of flow holes are opened on both sides of the outer wall of the placement mold 4. A sealing ring is embedded in the inner wall of the mating hole, located on the outer wall of the connecting pipe 5. Material can be fed into the inner side of the placement mold 4 to cooperate with the pressurizer body 3 for pressurization. At this time, the electric fan 7 can be started to draw air through the vent. The air is blown through the connecting pipe 5 to the inner side of the annular groove to dissipate heat from the placement mold 4. When the electric fan 7 rotates, it can also cooperate with the movable plate 16 and the movable groove to drive the conveying blades 10 inside the conveying cylinder 8 to rotate, so that the water source circulates and cools the cooling pipe 9, the first circulation pipe 11, and the second circulation pipe as the electric fan 7 continues to rotate.

[0027] Secondly, in this embodiment, the linkage circulation assembly includes multiple sets of conveying cylinders 8 overlapping one side of the outer wall of two sets of blower cylinders 6. One side of one set of conveying cylinders 8 is equipped with a cooling pipe 9 extending into the inner side of the annular groove. One section of the cooling pipe 9 is spiral-shaped. The end of the cooling pipe 9 extending to the outside of the mold 4 is fixedly connected to one end of the other set of conveying cylinders 8. Conveying blades 10 are rotatably connected inside the two sets of conveying cylinders 8. The conveying direction of one set of upper conveying blades 10 is from bottom to top, and the conveying direction of the other set of lower conveying blades 10 is from top to bottom. A first circulation pipe 11 is installed at the bottom end of one set of conveying cylinders 8, and a second circulation pipe is installed at the bottom end of the other set of conveying cylinders 8. A movable plate 16 is installed at the axis on the other side of the electric fan 7, and a rotating column 17 is installed at the axis of the conveying blade 10. The rotating column 17 and the conveying cylinder 8 are rotatable. The rotating column 17 extends to one end of the outer side of the conveying cylinder 8 and has a movable groove. The movable plate 16 is slidably connected to the movable groove. The storage component includes a storage box 18 installed between the opposite ends of the first circulation pipe 11 and the second circulation pipe passing through the base 1. An observation window is embedded on one side of the outer wall of the storage box 18. Multiple sets of heat dissipation fins 19 are embedded on the other end of the storage box 18. A water inlet pipe is embedded on one end of the top of the cooling pipe 9. The top of the water inlet pipe is secured with a sealing cap by a latch. When the air blown by the electric fan 7 reaches the inside of the annular groove, it can also cool the water source inside the cooling pipe 9 that has become hot. After the water source enters the inside of the storage box 18, the heat can be absorbed by the multiple sets of heat dissipation fins 19 and dissipated outward, accelerating the cooling speed of the water source. When the water source circulating and cooling inside is insufficient, the sealing cap on the cooling pipe 9 can be opened to add water source through the water inlet pipe.

[0028] In addition, in this embodiment, a pressing groove is provided on one side of the outer wall of the conveying cylinder 8, and a pressing plate 12 is slidably connected to the inner side of the pressing groove. An extension plate is installed at one end of the pressing plate 12, and one end of the extension plate is fixedly connected to the outer wall of the blower 6. An abutment groove is provided inside the conveying cylinder 8 on one side of the pressing groove, and an abutment block 13 is slidably connected to the inner side of the abutment groove. The contact ends of the abutment block 13 and the pressing plate 12 are both provided with ramps. A connecting rod is installed at one end of the abutment block 13 extending to the outside of the abutment groove. If the electric fan 7 needs to be inspected and maintained, simply hold the first latching groove on the outer wall of the second connecting plate to move the second connecting plate, so that the second connecting plate drives the two sets of first springs 15 to extend, and pull the abutment block 13 away from the protruding end on the pressing plate 12. At this time, the blower 6 can be held and pulled off to inspect and maintain the electric fan 7.

[0029] Furthermore, in this embodiment, a first connecting plate 14 is slidably connected to the outer side of the connecting rod. One end of the first connecting plate 14 is fixedly connected to the outer wall of the conveying cylinder 8. A first spring 15 is installed at both ends of the other side of the outer wall of the first connecting plate 14. A second connecting plate is installed at the other end of the first spring 15. The second connecting plate is fixedly connected to one end of the connecting rod. A first snap-pull groove is opened on the other side of the outer wall of the second connecting plate. After maintenance, the blower 6 can be re-attached to the conveying cylinder 8, allowing the pressing plate 12 to enter the pressing groove and contact the abutting block 13. The two slopes squeeze each other, forcing the abutting block 13 to retract to the inside of the abutting groove. After the pressing plate 12 is completely pushed into the inside of the pressing groove, the abutting block 13 can be driven by the first spring 15 to pop out and abut against the protruding end of the pressing plate 12. At this time, the movable plate 16 can also be engaged with the movable groove to drive the conveying blade 10 to rotate in the future.

[0030] When using the automatic glass and ceramic pressure furnace of this solution, the material can be fed into the inner side of the placement mold 4 and pressurized in conjunction with the main body 3 of the press. At this time, the electric fan 7 can be started to draw air through the vent. The air is blown through the connecting pipe 5 to the inner side of the annular groove to dissipate heat from the placement mold 4. When the electric fan 7 rotates, it can also work with the movable plate 16 and the movable groove to drive the conveying blades 10 inside the conveying cylinder 8 to rotate, so that the water source circulates and cools the cooling pipe 9, the first circulation pipe 11 and the second circulation pipe as the electric fan 7 rotates continuously. When the air blown by the electric fan 7 to the inner side of the annular groove, it can also cool the water source inside the cooling pipe 9 that has become hot. After the water source enters the inner side of the storage tank 18, the heat can be absorbed by multiple sets of heat dissipation fins 19 and dissipated outward, accelerating the cooling speed of the water source. When the water source for inner circulation cooling is insufficient, the fan can be turned on. Water is added to the sealing cap on the cooling pipe 9 through the water inlet pipe. If the electric fan 7 needs to be inspected and maintained, simply fasten the first latching groove on the outer wall of the second connecting plate to move the second connecting plate. This causes the second connecting plate to extend the two sets of first springs 15, pulling the abutting block 13 away from the protruding end on the pressing plate 12. At this time, the blower 6 can be held and pulled off to inspect and maintain the electric fan 7. After the inspection and maintenance are completed, the blower 6 can be reattached to the conveying cylinder 8, allowing the pressing plate 12 to enter the pressing groove and contact the abutting block 13. The inclined pressure of the two forces the abutting block 13 to retract into the inner side of the abutting groove until the pressing plate 12 is completely pushed into the inner side of the pressing groove. Then, the abutting block 13 can be pushed out by the first spring 15 to abut against the protruding end of the pressing plate 12. At this time, the movable plate 16 can also be engaged with the movable groove to drive the conveying blade 10 to rotate.

[0031] The control method of this utility model is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Since this utility model is used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0032] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
