Description

Technical Field

[0001] The invention relates to the technical field of quartz plate annealing, and in particular to an annealing device for a fused quartz plate which is convenient for discharging. Background Art

[0002] Fused quartz plate is a plate made of high-purity fused quartz. Pure quartz sand is heated to above 1800℃ in an electric furnace to melt it, and then cut with professional cutting equipment to produce fused quartz plates of various sizes. It can withstand temperatures up to 1750℃ or even higher, and can maintain stable performance in high-temperature environments. It is not prone to deformation, cracking and other problems. Therefore, it is often used in fields such as thermal insulation materials for high-temperature furnaces. It is almost unaffected by any chemical substances, has good corrosion resistance, can maintain reliability and durability in a variety of chemical environments, and can be used for equipment parts that come into contact with corrosive substances in industries such as chemical and food.

[0003] Annealing of fused quartz plates is mainly to eliminate the internal stress generated during the processing of fused quartz plates. After the annealing process is completed, the equipment is cooled to a certain temperature, and the operator wears heat-insulating gloves and directly enters the equipment to take out the quartz plate. This method is simple and direct, but there are certain safety risks and low efficiency. It is not suitable for large equipment or mass production. Summary of the invention

For example, solid residues produced by the decomposition of impurities may adhere to the heating element or the thermal insulation material, reducing the heating efficiency. The quartz plate has good thermal conductivity and thermal insulation performance. It needs to be cleaned and maintained regularly to ensure the normal operation of the annealing equipment. If there are impurities left on the quartz plate, the thermal conductivity of the impurities is usually different from that of quartz. For example, the thermal conductivity of metal impurities is generally higher than that of quartz. When these impurities exist, the local thermal conductivity of the quartz plate will be changed. During the annealing process, the heat transfer will be disturbed, resulting in uneven heating of the quartz plate. In this way, at the annealing temperature, the temperature difference of different parts of the quartz plate may exceed the expected range, affecting the stress elimination effect.

Even new stress may be generated in some parts, so that the quartz plate can contact with the contact mechanism when the conveying mechanism is conveying, so that the contact mechanism can clean the contact bottom surface of the quartz plate;

[0011] Preferably, the contact mechanism comprises a contact plate, the side of the contact plate is fixedly connected to the inner side of the feed table, the top of the contact plate is fixedly connected to a contact frame, both sides of the contact frame are slidably connected to rubber plates, the side of the rubber plate away from the contact frame is in contact with the side of the conveying mechanism, and both sides of the top of the contact frame are fixedly connected to cleaning components; when the conveying mechanism drives the quartz plate to move continuously, the cleaning component continuously contacts and moves with the bottom of the quartz plate, so that the cleaning component can clean the bottom of the quartz plate, and at the same time, the cleaning component moves on the contact frame A rubber plate is disposed against the side of the roller in the conveying mechanism, so that when the roller rotates inside the feed table, the rubber plate can move against the side of the roller, so that the rubber plate can clean the side of the roller, thereby preventing impurities on the bottom contact surface of the quartz plate from adhering to the roller when the quartz plate is conveyed, thereby preventing some impurities attached to the roller from adhering to the quartz plate when the bottom of the quartz plate cleaned by the cleaning assembly passes through the roller, thereby leaving residues at the bottom of the quartz plate, increasing the cleaning and maintenance costs of the equipment;

[0012] The cleaning component comprises a cleaning frame, the bottom of the cleaning frame is slidably connected to the inner side of the contact frame, the inner side of the cleaning frame is rotatably connected to a cleaning roller, the cleaning frame is provided with sliding grooves on both sides away from the cleaning roller, the inner side of the sliding groove is slidably connected to a sliding shaft, the top of the sliding shaft is fixedly connected to a sliding plate, the side surface of the sliding plate is slidably connected to the inner side of the sliding groove, the top of the sliding plate is fixedly connected to a cleaning block, the sliding shaft is sleeved with a first spring, the top of the first spring is fixedly connected to the bottom of the sliding plate, and the bottom of the first spring is fixedly connected to the inner side of the sliding groove; when the quartz plate is transported and moved by the conveying mechanism, when the bottom of the quartz plate passes through the cleaning frame When the cleaning block is cleaned, the sliding plate drives the cleaning block to contact the bottom of the quartz plate, so that the cleaning block cleans the impurities adhered to the bottom of the quartz plate. At the same time, a cleaning roller is arranged in the middle of the cleaning frame, and the cleaning roller can clean and wipe the cleaned area of ​​the quartz plate with the cleaning block.

[0013] The beneficial effects of the present invention are as follows:

[0014] 1. The present invention sets a feeding mechanism. After the annealing work on the quartz plate is completed, the first electric hydraulic cylinder is turned on. The output end of the first electric hydraulic cylinder drives the connecting plate to move inside the feeding arm through the connecting shaft, so that the height adjustment work is performed appropriately according to the quartz plates of different sizes and thicknesses, so that the side of the quartz plate can be better clamped and fixed appropriately. The double-axis motor is turned on and the output end of the double-axis motor drives the two second screw rods inside the connecting plate to rotate, so that the clamping arm rotates on the second screw rod, so that the clamping arm clamps and fixes the two sides of the quartz plate after cooling in the annealing furnace.

[0015] 2. The present invention sets a feeding mechanism.

At the same time, the second electric hydraulic cylinder is turned on and the output end of the second electric hydraulic cylinder drives the fixed housing to move downward inside the sliding arm. At the same time, the third motor inside the fixed housing is turned on and the output end of the third motor drives the rotating block to rotate, so that the rotating block drives the clamping mechanism to rotate. Therefore, the placement position of the quartz plate is appropriately adjusted according to different angles. After the quartz plate is clamped and fixed by the clamping mechanism, the quartz plate is clamped and placed on the feeding component, so that the feeding component transports the quartz plate to the annealing furnace for annealing.

[0016] 3. The present invention provides a feeding component. When the loading mechanism clamps the quartz plate and places it on the feeding table, the conveying mechanism is opened to convey the quartz plate to the annealing furnace for subsequent annealing. At the same time, when the conveying mechanism conveys the quartz plate, since the conveying mechanism contacts and moves with the bottom of the quartz plate, impurities on the quartz plate may leave residues in the equipment during the annealing process, increasing the cleaning and maintenance costs of the equipment.

[0017] 4. The present invention sets a contact mechanism. When the conveying mechanism drives the quartz plate to move continuously, the cleaning component continuously contacts and moves with the bottom of the quartz plate, so that the cleaning component can clean the bottom of the quartz plate. At the same time, rubber plates are set against each other on the sides of the rollers in the contact frame and the conveying mechanism, so that when the rollers rotate on the inner side of the feed table, the rubber plates can move against the sides of the rollers, so that the rubber plates can clean the sides of the rollers, thereby preventing impurities on the contact surface of the bottom of the quartz plate from adhering to the rollers when the quartz plate is conveyed, thereby preventing some impurities attached to the rollers from adhering to the quartz plate when the bottom of the quartz plate cleaned by the cleaning component passes through the rollers, thereby leaving residues on the bottom of the quartz plate and increasing the cleaning and maintenance costs of the equipment.

If there are impurities remaining on the quartz plate, the thermal conductivity of the impurities is usually different from that of quartz. For example, the thermal conductivity of metal impurities is generally higher than that of quartz. When these impurities exist, the local thermal conductivity of the quartz plate will be changed. During the annealing process, the heat transfer will be disturbed, resulting in uneven heating of the quartz plate. In this way, at the annealing temperature, the temperature difference of different parts of the quartz plate may exceed the expected range, affecting the stress elimination effect. The internal stress that should have been evenly eliminated may not be completely eliminated due to the local temperature being too high or too low, and even new stress may be generated in some parts, so that the quartz plate can be transported by the conveying mechanism 33.

When the cleaning block 3447 cleans the bottom of the quartz plate, the extrusion force between the cleaning block 3447 and the impurities adhering to the bottom of the quartz plate is greater than the tensile force of the first spring 3446, so that the cleaning block 3447 slides downward in the inner side of the sliding groove 3443 through the sliding plate 3444 and the sliding shaft 3445, so as to avoid excessive extrusion force between the cleaning block 3447 and the impurities adhering to the bottom of the quartz block, which will cause extrusion damage to the side of the cleaning block 3447.

[0042] The specific workflow is as follows:

[0043] During operation, the molten quartz plate is placed on the feeding component 3 through the connecting component 6, and the molten quartz plate is fed into the annealing furnace 1 through the feeding component 3. By closing the furnace door 4, the annealing furnace 1 is mainly composed of a furnace body, a heating element, a temperature control system and other parts. The furnace body is generally made of a high-temperature resistant steel shell, and the interior is lined with insulation materials such as ceramic fibers to reduce heat loss. The heating elements are mostly resistance wires, which are evenly distributed on both sides or the bottom of the furnace body. The molten quartz plate placed in the furnace is heated by thermal radiation. When the annealing furnace 1 is turned on, the current generates heat through the resistance wire, and the heat is transferred to the quartz plate by radiation. The temperature control system monitors the temperature in the furnace through temperature sensors such as thermocouples, and adjusts the power of the heating element according to the set annealing temperature curve. For example, at the beginning of annealing, the temperature gradually increases, and the power of the heating element is relatively large. ; When approaching the annealing temperature, the power is reduced to slowly raise the temperature to the target temperature, and then maintained for a period of time to allow the stress inside the quartz plate to be fully released. After the annealing work of the molten quartz plate is completed, the molten quartz plate in the annealing furnace 1 is moved to the cooling component 2 through the connecting component 6. The cooling component 2 is a combination of natural cooling and forced air cooling. After the annealing process is completed, the natural cooling method is first used to slowly cool the molten quartz plate in the furnace so that the internal structure gradually stabilizes. When the temperature drops to a certain level, the forced air cooling system is turned on. The forced air cooling system introduces cold air into the furnace by setting vents and fans in the cooling component 2 to accelerate the cooling process. This step-by-step cooling method can avoid new stress on the quartz plate caused by a sudden drop in temperature, thereby moving the cooled quartz plate to the discharge table 5 through the connecting component 6 for discharge work;

[0044] When the quartz plate is annealed, the second motor 643 is turned on, and the output end of the second motor 643 drives the third screw rod 641 to rotate inside the connecting rod 62, so that the sliding arm 642 moves inside the connecting rod 62. At the same time, the second electric hydraulic cylinder 644 is turned on, and the fixed housing 645 is driven by the output end of the second electric hydraulic cylinder 644 to move downward inside the sliding arm 642. At the same time, the third motor 646 inside the fixed housing 645 is turned on, and the output end of the third motor 646 drives the rotating block 647 to rotate, so that the rotating block 647 drives the clamping mechanism 648 to rotate, so that the placement position of the quartz plate at different angles is appropriately adjusted. After the quartz plate is clamped and fixed by the clamping mechanism 648, the quartz plate is clamped and placed on the feeding component 3, so that the feeding component 3 transports the quartz plate to the annealing furnace 1 for annealing.

[0045] After the annealing work on the quartz plate is completed, the first electric hydraulic cylinder 634 is turned on, and the output end of the first electric hydraulic cylinder 634 drives the connecting plate 636 to move inside the lower arm 631 through the connecting shaft 635, so that the height adjustment work can be carried out according to the quartz plates of different sizes and thicknesses, so that the side of the quartz plate can be properly clamped and fixed, and the dual-axis motor 639 is turned on, and the output end of the dual-axis motor 639 drives the two second screw rods 637 inside the connecting plate 636 to rotate, so that The clamping arm 638 is rotated on the second screw rod 637, so that the clamping arm 638 clamps and fixes the two sides of the quartz plate after cooling in the annealing furnace 1. By turning on the first motor 633, the first screw rod 632 is driven to rotate inside the connecting rod 62 through the output end of the first motor 633, so as to drive the clamped quartz plate to pull, so as to move the cooled quartz plate to the discharge table 5 for discharge, which can effectively avoid the mistakes and risks that may occur in manual unloading, and is suitable for large-scale automated production;

[0046] When the loading mechanism 64 clamps the quartz plate and places it on the feeding table 31, the conveying mechanism 33 is turned on to convey the quartz plate to the annealing furnace 1 for subsequent annealing. At the same time, when the conveying mechanism 33 conveys the quartz plate, since the conveying mechanism 33 moves in contact with the bottom of the quartz plate, impurities on the quartz plate may leave residues in the equipment during the annealing process, increasing the cleaning and maintenance costs of the equipment. For example, solid residues produced by the decomposition of impurities may adhere to the heating element or the insulation material, reducing the heating efficiency and insulation performance. The equipment needs to be cleaned and maintained regularly to ensure the normal operation of the annealing equipment. If there are impurities remaining on the quartz plate, the thermal conductivity of the impurities is usually Different from quartz, for example, the thermal conductivity of metal impurities is generally higher than that of quartz. When these impurities exist, the local thermal conductivity of the quartz plate will be changed. During the annealing process, the heat transfer will be disturbed, resulting in uneven heating of the quartz plate. In this way, at the annealing temperature, the temperature difference of different parts of the quartz plate may exceed the expected range, affecting the stress elimination effect. The internal stress that should be uniformly eliminated may not be completely eliminated due to the local temperature being too high or too low. Even new stress may be generated in some parts, so that the quartz plate can be in contact with the contact mechanism 34 when being transported by the conveying mechanism 33, so that the contact mechanism 34 can clean the contact bottom surface of the quartz plate;

[0047] When the conveying mechanism 33 drives the quartz plate to move continuously, the cleaning component 344 continuously contacts and moves with the bottom of the quartz plate, so that the cleaning component 344 can clean the bottom of the quartz plate. At the same time, a rubber plate 343 is provided on the contact frame 342 and the side of the roller in the conveying mechanism 33, so that when the roller rotates inside the feed table 31, the rubber plate 343 can move against the side of the roller, so that the rubber plate 343 can clean the side of the roller, thereby preventing impurities on the contact surface of the bottom of the quartz plate from adhering to the roller when the quartz plate is conveyed, thereby preventing some impurities attached to the roller from adhering to the quartz plate when the bottom of the quartz plate cleaned by the cleaning component 344 passes through the roller, thereby leaving residues at the bottom of the quartz plate, increasing the cleaning and maintenance costs of the equipment;

[0048] When the quartz plate is transported and moved by the conveying mechanism 33, when the bottom of the quartz plate passes through the cleaning rack 3441, the sliding plate 3444 drives the cleaning block 3447 to contact the bottom of the quartz plate, so that the cleaning block 3447 cleans the impurities adhered to the bottom of the quartz plate. At the same time, a cleaning roller 3442 is provided in the middle of the cleaning rack 3441, and the cleaning roller 3442 can clean and wipe the cleaning block 3447 on the cleaned area of ​​the quartz plate. When the cleaning block 3447 cleans the bottom of the quartz plate, the extrusion force between the cleaning block 3447 and the impurities adhered to the bottom of the quartz plate is greater than the tensile force of the first spring 3446, so that the cleaning block 3447 slides downward in the inner side of the sliding groove 3443 through the sliding plate 3444 and the sliding shaft 3445, thereby avoiding excessive extrusion force between the cleaning block 3447 and the impurities adhered to the bottom of the quartz block, which will cause extrusion damage to the side of the cleaning block 3447.
