Description

Technical Field

[0001] The present invention relates to a production process of a quartz pot for cooking and production equipment used therefor. Background Art

[0002] Patent with publication number CN103803780A: Manufacturing method of cooking crystal pot. The cooking crystal pot is made from high-purity quartz sand with SiO2 purity above 99.9%. It is melted at high temperature by the electric arc method and completed through post-treatment. A certain thickness of high-purity quartz sand is evenly added to a rotating graphite or steel mold. The mold is returned to the melting chamber, and the graphite electrode is lowered to the center position of the mold. According to the mold size and the thickness of the added quartz sand, the corresponding current magnitude and melting time are set in the control room, and then it is melted by power-on. After the pot blank is melted, the graphite electrode is lifted, the mold is lowered, demolding and pot taking are carried out, and the outer floating sand is brushed off with a wire brush. After cooling, it is cut, polished, cleaned, and dried. The upper edge and the outside of the pot are polished, or the upper edge and the outside of the pot are burned into a vitreous state with a hydrogen-oxygen flame, and then it is cleaned, dried, and packaged. Therefore, the existing cooking quartz pots are made by the melting and forming method. The paper "Research on the Manufacture of Large-Diameter Opaque Quartz Glass Tubes by Centrifugal Electric Melting Method" published by Zhang Shixuan in the 30th volume, issue 3 of "Bulletin of the Chinese Ceramic Society" in June 2011 mentioned that the centrifugal electric melting method is to trim the powder into a predetermined shape in a rotary furnace and melt it, that is, to complete processes such as feeding and powder forming in a centrifugal furnace device... From a technological perspective, this change in the manufacturing method is from static to dynamic, from the uncontrollability of the shape of the melted product to obtaining a product with precise dimensions according to a pre-conceived idea. Moreover, compared with the traditional electric melting and blowing method, the production efficiency can be increased by 4 times, the unit power consumption is reduced by 50%, and the unit material consumption is reduced by 50%. In the power range of quartz melting, as the melting power increases, the melting rate accelerates, the melting cycle shortens, and the melting power consumption shows a trend of first decreasing to a minimum value at a certain power and then increasing. Therefore, in order to accelerate the melting rate and shorten the melting cycle, it is necessary to increase the melting power to a certain extent. Although it finally finds a suitable melting power to minimize the melting power consumption and the melting cycle is relatively short, it needs to study the relationship between the melting power and the quartz melting rate, melting cycle, and melting power consumption, and it requires investing technical R & D personnel, and both manpower and time need to be increased. The patent with publication number CN102786205B also mentioned that currently, people traditionally use the vertical quartz melting method for melting quartz. The overall structure consists of a furnace body, a furnace cover, and large and small furnace frames. During operation, the furnace is filled with heat-insulating and quartz fine materials, and a sealed space is formed by the combination of the furnace body and the furnace cover... The quartz ingots produced by this quartz melting method have a very low utilization rate (less than 30%) in the deep processing of special quartz products (such as thick-walled tubes, conical tubes, quartz rings, plates, etc.), and even cannot achieve the purpose, and the power consumption is huge, which does not meet the needs of modern energy-saving production. Although the centrifugal melting and forming method for preparing quartz products can reduce a lot of melting power consumption compared with the existing vertical quartz melting method or electric melting and blowing method, due to the not-light weight of the furnace body and the need for continuous rotation during centrifugal forming, the melting power consumption is still relatively large. Summary of the Invention

[0003] The object of the present invention is to overcome the defects existing in the prior art and provide a production process for a quartz pot for cooking. Since the rotation direction of the feeding mechanism is opposite to that of the furnace body, the furnace body can be allowed to rotate at a speed lower than the designed speed to reduce the melting power consumption. Moreover, there is no need to invest in technical R & D personnel, reducing the manpower, and the early-stage technical R & D time can be saved.

[0004] To achieve the above object, the technical solution of the present invention is to design a production process for a quartz pot for cooking, which is carried out in the following technological steps in sequence: start the rotary furnace, feed materials: add quartz powder into the furnace body of the rotary furnace, energize for melting, cool and anneal, and grind and engrave.

[0005] A further technical solution is that there is also a process of installing electrodes between the processes of shaping by the manipulator and energizing for melting; there is also a trimming process between the processes of feeding materials and energizing for melting; the trimming process is: shaping by the manipulator. If an electromagnetic induction heating device is adopted, then between the processes of shaping by the manipulator and energizing for melting, instead of the process of installing electrodes, there is a process of installing the electromagnetic induction heating device.

[0006] A further technical solution is that the process of starting the rotary furnace is: the rotary furnace rotates, after the moving platform moves close to the furnace body of the rotary furnace, the feeding mechanism feeds materials into the furnace body, and the heating device melts the quartz powder into the required quartz cookware; the feeding mechanism rotates itself during the feeding process and its rotation direction is opposite to that of the furnace body of the rotary furnace. Since the rotation direction of the feeding mechanism is opposite to that of the furnace body, the furnace body can be allowed to rotate at a speed lower than the designed speed to reduce the energy consumption (after all, the rotation of the furnace body requires more energy, while the feeding mechanism is light in weight and requires less energy for rotation, but the reverse rotation of the two allows the furnace body to rotate at a lower speed and still ensure the required centrifugal forming effect). Moreover, there is no need to invest in technical R & D personnel, reducing the manpower, and the early-stage technical R & D time can be saved.

[0007] A further technical solution is that the driving motor operates to move the feeding gun or the heating device up and down;

[0008] When the feeding gun moves to the rotation axis of the furnace body, the heating device moves to other heights to ensure that only one component of the feeding gun or the electrode heating device is located at the rotation axis of the furnace body at the same time. Since only the feeding gun or the electrode heating device is located at the rotation axis of the furnace body at the same time, when the feeding gun feeds materials, the electrode heating device is far away from the furnace body, and when heating, the feeding gun is far away from the furnace body, avoiding mutual interference.

[0009] The technical solution provided by the present invention is also a production device for a quartz pot for cooking, which is used in the production process of the quartz pot for cooking. The production device includes a rotary furnace, and the rotary furnace includes a furnace body. A gear ring is fixedly sleeved outside the furnace body. The gear ring meshes with a gear, and the gear is fixedly connected to the output shaft of a reduction motor. Both ends of the furnace body are rotatably connected to a furnace frame through bearings. A moving platform is arranged outside the furnace body, and a feeding mechanism and a heating device are arranged on the moving platform. The feeding mechanism is rod-shaped and is located on the rotation axis of the furnace body of the rotary furnace. The feeding mechanism rotates by itself during the feeding process, and its rotation direction is opposite to the rotation direction of the furnace body of the rotary furnace. A lead screw-nut mechanism is arranged on the moving platform, and a feeding gun and the heating device are fixedly connected to the nut of the lead screw-nut mechanism. Since the rotation direction of the feeding mechanism is opposite to that of the furnace body, the furnace body can be allowed to rotate at a speed lower than the designed speed, thereby reducing the melting power consumption. Moreover, there is no need to study the relationship between the melting power, the quartz melting rate, the melting cycle, and the melting power consumption, and no technical R & D personnel need to be invested, thus reducing both manpower and time.

[0010] A further technical solution is that a manipulator device for shaping is also arranged on the moving platform; the heating device is an electrode heating device. The heating device can also be an electromagnetic induction heating device. If an electromagnetic induction heating device is adopted, there will be no manipulator shaping process, and the coverage range of the electromagnetic induction heating device only covers the range of the furnace body where the finally formed quartz cookware is located. If it is an electrode heating device, it is installed at the end of the furnace body; if it is an electromagnetic induction heating device, the electromagnetic coil is sleeved outside the furnace body.

[0011] A further technical solution is that the feeding mechanism is a feeding gun. The barrel at the outlet of the feeding gun is rod-shaped, and a lengthened discharging pipe is rotatably connected at the outlet of the feeding gun. The lengthened discharging pipe is rotationally and hermetically connected to the outlet of the feeding gun. A structure for realizing the rotation of the lengthened discharging pipe is arranged on the feeding mechanism. The lengthened discharging pipe rotates by itself during the feeding process, and its rotation direction is opposite to the rotation direction of the furnace body of the rotary furnace.

[0012] A further technical solution is that the structure includes a reduction motor fixedly connected to the outer wall of the feeding gun. A gear is fixedly connected to the output shaft of the reduction motor, and a second gear ring meshing with the gear is fixedly sleeved on the outer wall of the lengthened discharging pipe.

[0013] The advantages and beneficial effects of the present invention are as follows: Since the rotation direction of the feeding mechanism is opposite to that of the furnace body, the furnace body can be allowed to rotate at a speed lower than the designed speed to reduce energy consumption (after all, the rotation of the furnace body requires more energy, while the feeding mechanism is light in weight and requires less energy for rotation. However, the reverse rotation of the two allows the furnace body to rotate at a lower speed to ensure the required centrifugal forming effect). Moreover, no technical R & D personnel need to be invested, reducing manpower and saving the previous technical R & D time.

[0014] Since only the feeding gun or the electrode heating device is located on the rotary axis of the furnace body at the same time, the electrode heating device is far away from the furnace body when the feeding gun is feeding, and the feeding gun is far away from the furnace body during heating, avoiding mutual interference.

[0015] Since the feeding mechanism rotates in the opposite direction to the furnace body, the furnace body can be allowed to rotate at a speed lower than the designed speed. This reduces the melting power consumption, and there is no need to study the relationship between the melting power, the quartz melting rate, the melting cycle and the melting power consumption, nor to invest technical R & D personnel, thus reducing both manpower and time.

Specific implementation mode

[0031] The following combines the drawings and embodiments to further describe the specific implementation mode of the present invention. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and cannot be used to limit the protection scope of the present invention.

[0032] Embodiment 1: As Figure 1 shown, the present invention is a production process of a quartz pot for cooking, formed by centrifugal method and melted under the required temperature conditions to imitate natural crystal (so this process also uses molten quartz powder at a certain temperature {higher than 1600 °C} and is prepared by centrifugal forming), and then ground and carved with an intelligent device.

[0033] The process is as follows: Start the rotary furnace → Feeding: Add quartz powder into the furnace body of the rotary furnace → Trimming: The manipulator makes the shape → Electrode installation → Electrifying and melting → Cooling and annealing → Grinding and carving.

[0034] Before feeding, the screw-nut mechanism operates to adjust the height of the feeding gun to the position of the rotation axis of the furnace body. Then, the moving platform moves back and forth to cooperate with the feeding gun to spray quartz powder, so as to fix quartz powder on the entire inner sidewall of the furnace body. The moving platform moves outwards, and the screw-nut mechanism of the feeding gun operates to adjust the height of the feeding gun to move away from the furnace body (for example, at the upper height or lower height of the furnace body). The screw-nut mechanism of the manipulator operates to make the height of the manipulator meet the requirement that the manipulator can extend into the furnace body after the moving platform approaches the furnace body instead of being blocked by the edge of the furnace body. The screw-nut mechanism of the manipulator operates in cooperation with the movement of the moving platform to complete the multi-trajectory operation of the manipulator (the multi-trajectory operation of the manipulator is specifically: it can reciprocate along the rotation axis direction of the furnace body of the rotary furnace to trim the shape of the powder; it can also move radially and adjust its angle to control the inner diameter and angle of the formed powder). After the shaping is completed, the moving platform moves outwards, and the screw-nut mechanism of the manipulator operates to make the position of the manipulator meet the requirement that when the moving platform approaches the furnace body again, the manipulator is located above or below the furnace body (that is, not at the high position of extending into the furnace body). The screw-nut mechanism of the electrode heating device operates to make the position of the electrode heating device meet the requirement that after the moving platform approaches the furnace body again, the electrode heating element can be placed in the furnace. After the electrode heating element is placed in the furnace, the quartz powder is melted into a quartz pot according to a predetermined program (the attached drawing is only a schematic diagram. In fact, the barrel length at the outlet of one of the feeding guns is much longer than that in the schematic diagram to better penetrate into the furnace body and ensure that the entire inner sidewall of the furnace body can fix quartz powder {the quartz powder is fixed on the inner sidewall of the furnace body due to centrifugal force}).

[0035] Example 2: The difference from Example 1 is that, as Figures 2 to 5 shown (for the convenience of illustration, Figure 3The mobile platform is not shown). The rotary furnace includes a furnace body 1. A gear ring 2 is fixedly sleeved outside the furnace body. The gear ring 2 meshes with a gear 3, and the gear is fixedly connected to the output shaft of a reduction motor 4. Both ends of the furnace body are rotatably connected to a furnace frame 16 through bearings 15 (other structures of the rotary furnace are prior art. For example, through a mobile platform 9, a feeding mechanism, a manipulator device for shaping, and an electrode heating device 10 are arranged on the mobile platform. After moving close to the furnace body of the rotary furnace through the mobile platform, the feeding mechanism feeds the furnace body, the manipulator trims the quartz powder in the rotary furnace into a predetermined shape, and the electrode heating device melts the quartz powder into the required quartz cookware); the feeding mechanism is rod-shaped and is located on the rotation axis of the furnace body 1 of the rotary furnace; the feeding mechanism rotates during the feeding process and its rotation direction is opposite to that of the furnace body 1 of the rotary furnace. This is equivalent to increasing the rotation speed of the furnace body, allowing the furnace body to rotate at a speed lower than the designed speed to reduce energy consumption (after all, the rotation of the furnace body requires more energy, while the feeding mechanism is light and requires less energy for rotation. However, when the two rotate in opposite directions, the furnace body can rotate at a lower speed and still ensure the required centrifugal forming effect); a lead screw-nut mechanism 11 is arranged on the mobile platform, and the feeding gun and the electrode heating device are fixedly connected to the nut of the lead screw-nut mechanism. The feeding gun (or the electrode heating device) is moved up and down by a driving motor (when the feeding gun moves to the rotation axis of the furnace body, the electrode heating device moves to another height to ensure that only one component is located at the rotation axis of the furnace body at the same time).

[0036] The feeding mechanism can adopt a feeding gun 5 of the prior art. A lengthened discharge pipe 6 is rotatably connected to the outlet of the feeding gun 5, and the lengthened discharge pipe 6 is rotationally and hermetically connected to the outlet of the feeding gun;

[0037] A reduction motor is fixedly connected to the outer wall of the feeding gun 5. A gear is fixedly connected to the output shaft of the reduction motor. The outer wall of the lengthened discharge pipe is fixedly sleeved with a second gear ring 7 that meshes with the gear (by starting the reduction motor on the outer wall of the feeding gun to drive the lengthened discharge pipe to rotate. The discharge port 8 of the lengthened discharge pipe 6 is located on the side surface near the end of the lengthened discharge pipe. In this way, the material ejected when the lengthened discharge pipe rotates is ejected towards the inner wall of the furnace body. Cooperating with the reverse rotation of the furnace body, the furnace body can rotate at a speed lower than the designed speed, reducing the melting power consumption; for the convenience of illustration, the feeding pipe of the feeding gun in the figure is not shown).

[0038] Embodiment 3: The difference from Embodiment 2 is that, as Figure 6 、 Figure 7 shown, the feeding mechanism can adopt a feeding gun 5 of the prior art. A lengthened discharge pipe 6 is rotatably connected to the outlet of the feeding gun 5, and the lengthened discharge pipe 6 is rotationally and hermetically connected to the outlet of the feeding gun;

[0039] The inner wall of the extended discharge pipe 6 is fixedly connected with a spiral protrusion 12. After such a setting, when the feeding gun sprays materials, the extended discharge pipe rotates automatically without a driving mechanism for driving the rotation of the extended discharge pipe (when spraying quartz powder, due to the impact of the sprayed materials, it first impacts the spiral protrusion on the inner wall of the extended discharge pipe, making the extended discharge pipe tend to rotate, and continuous spraying makes the rotation continue) (unlike Embodiment 2, which requires a second gear ring, a gear, and a reduction motor); it can avoid setting the driving mechanism for driving the extended discharge pipe outside the extended discharge pipe as in Embodiment 2 (setting it outside is likely to be contacted and worn by the sprayed quartz powder).

[0040] Embodiment 4: The difference from Embodiment 2 is that, as Figure 8 , Figure 9 shown, the feeding mechanism can adopt a feeding gun 5 of the prior art. A folded shaft 13 is fixedly connected to the inner side wall at the outlet of the feeding gun 5. One section of the folded shaft 13 is perpendicular to the rotation axis at the gun nozzle of the feeding gun 5, and the other section of the folded shaft is collinear with the rotation axis at the gun nozzle of the feeding gun 5. An impeller 14 is rotatably arranged on the folded shaft. An extended discharge pipe 6 is arranged at the outlet of the feeding gun 5. The inner wall of the extended discharge pipe 6 is fixedly connected to the outer peripheral edge of the impeller 14. The extended discharge pipe 6 is rotationally and sealingly connected to the outlet of the feeding gun (the blades of the impeller are designed to satisfy that when the impeller is sprayed with materials by the feeding gun, the rotation direction of the impeller is opposite to the rotation direction of the furnace body; the impeller can also adopt a structure similar to the fan blades, so that more of the sprayed quartz powder can pass through the impeller, which can ensure the sufficiency of the sprayed quartz powder).

[0041] After such a setting, when the feeding gun sprays materials, the extended discharge pipe rotates automatically without a driving mechanism for driving the rotation of the extended discharge pipe (when spraying quartz powder, due to the impact of the sprayed materials, it first impacts the impeller, thereby driving the impeller to rotate, and then the impeller drives the extended discharge pipe to rotate) (unlike Embodiment 2, which requires a second gear ring, a gear, and a reduction motor); it can avoid setting the driving mechanism for driving the extended discharge pipe outside the extended discharge pipe as in Embodiment 2 (setting it outside is likely to be contacted and worn by the sprayed quartz powder).

[0042] Embodiment 5: The difference from Embodiment 1 is that, as Figure 10 shown, the production equipment further includes an auxiliary structure for forming a quartz pot. The auxiliary structure includes two moving platforms 9. The two moving platforms 9 are respectively arranged on both sides of the furnace body 1 and are located in the axial direction of the furnace body. The lengths of the feeding guns 5 on the two moving platforms are different, one is long and the other is short; a disc-shaped baffle 17 is further arranged in the middle of the furnace body. The central position of the baffle 17 is located on the rotation axis of the furnace body;

[0043] One of the moving platforms reciprocates back and forth when the furnace body 1 rotates to evenly distribute the quartz powder fixed on the inner side wall of the furnace body due to centrifugal force on the inner side wall of the furnace body. The other moving platform 9 moves to the nearest end of the furnace cavity after the furnace body rotates and then stops moving. The quartz powder sprayed by the feeding gun on this moving platform is used to form the bottom part of the quartz pot. When the furnace body rotates, the baffle also rotates to prevent the quartz powder from adhering to the baffle.

[0044] A cylindrical connecting piece 18 is fixedly connected to the middle of the baffle 17. The inner diameter of the cylindrical connecting piece 18 is larger than the outer diameter of the extended discharge pipe. A number of through holes are provided on the cylindrical connecting piece 18 to facilitate the final spraying of the quartz powder sprayed from the extended discharge pipe 6 onto the inner side wall of the furnace body. The rotation speed of the baffle can be relatively low compared to the extended discharge pipe or the furnace body, because as long as it is ensured that the sprayed quartz powder does not adhere to the baffle 17. The part of the cylindrical connecting piece 18 exposed outside the furnace body is rotated by a structure of a reduction motor cooperating with a gear and a gear ring (the reduction motor is fixedly connected to the furnace frame 16. A gear is fixedly connected to the output shaft of the reduction motor, and a gear ring meshes with the gear. The gear ring is fixedly sleeved on the cylindrical connecting piece). There is a gap between the baffle 17 and the end of the furnace body 1, and this gap is the thickness of the bottom of the quartz pot. The cylindrical opening of the cylindrical connecting piece 18 faces the extended discharge pipe 6 with a longer length.

[0045] Based on the existing quartz rotary centrifugal melting equipment, two feeding ports are designed. One feeding port is located at the center of the bottom of the quartz pot (or accurately, directly opposite the center of the bottom of the quartz pot), and a baffle is provided in front of it to control the wall thickness of the bottom. The other feeding port is still the existing feeding port, and the material is fed into the rotating furnace by a feeding gun. The material entering the furnace forms a "cylindrical" quartz sand layer due to the centrifugal force generated by the high-speed rotation of the furnace body.

[0046] Example 6: The difference from Example 1 is that, as Figures 11 to 14As shown in the figure, the rotary furnace includes a furnace body 1. A gear ring 2 is fixedly sleeved outside the furnace body. The gear ring 2 meshes with a gear 3, and the gear is fixedly connected to the output shaft of a reduction motor 4. Both ends of the furnace body are rotatably connected to a furnace frame 16 through bearings 15. The auxiliary structure includes a moving platform 9 arranged on one side of the furnace body. A feeding mechanism and an electromagnetic induction heating device 19 are arranged on the moving platform. After the moving platform moves close to the furnace body of the rotary furnace, the feeding mechanism feeds materials into the furnace body, and the electromagnetic induction heating device 19 melts the quartz powder into the required quartz cookware. The auxiliary structure also includes a profiling mold 20 of the quartz pot arranged inside the furnace body. The profiling mold 20 is in the shape of two concentric cylinders. The profiling mold can be provided with four or six (or more even numbers, arranged in a circular array inside the furnace body 1). The feeding mechanism is a feeding gun 5. A connecting pipe 21 is arranged at the end of the profiling mold 20 close to the feeding gun. The connecting pipe is connected to the profiling mold 20 through a gap. The other end of the connecting pipe is connected to a receiving pipe 22, and the receiving pipe 22 is connected to the discharge port of the feeding gun 5. The electromagnetic induction heating device 19 is located at the furnace body 1 where the profiling mold 20 is located (not covering the connecting pipe and the receiving pipe, so that only the quartz powder centrifugally fixed at the profiling mold is heated and melted). The end of the feeding gun is the discharge port. The sprayed quartz powder enters the gap between the large and small cylinders of the profiling mold through the receiving pipe and the connecting pipe. The pipe orifice of the receiving pipe is larger than the size of the end of the feeding gun, so that the feeding of the furnace body can be completed without the feeding gun contacting the furnace body (or the receiving pipe).

[0047] A profiling mold with concentric large and small cylinders is adopted. The material is added into the gap between the concentric large and small cylinders. The profiling mold of the concentric large and small cylinders keeps rotating, and is centrifugally formed, heated and melted into the shape of the required quartz cookware.

[0048] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
