Description

Technical Field

[0001] This invention belongs to the field of substrate glass manufacturing and relates to a multi-stage feed system and method for high-generation substrate glass furnaces. Background Technology

[0002] Substrate glass is a key material in LCD panels, widely used in terminal display devices such as televisions and computers. Its quality is closely related to the panel's resolution, light transmittance, thickness, weight, and viewing angle. The furnace, as a crucial piece of equipment in substrate glass production, primarily undertakes the task of high-quality melting of glass powder; the quality of this melting directly affects the quality of the substrate glass.

[0003] However, during the production process, problems such as collapse and deviation of the material pile due to instability of the material pile seriously affect the efficient melting of glass powder. At the same time, it disrupts the stability of kiln pressure and liquid level, causing fluctuations, which ultimately leads to defects in the substrate glass products. Therefore, the control of the material pile in the kiln is crucial.

[0004] Currently, the control of material piles in the material mountain is mainly achieved through trial adjustments of the process. However, due to the non-independence of the process, the adjustment processes that achieve material pile control will affect each other, making it impossible to achieve precise adjustment of the material pile. Furthermore, the state of the material pile after process adjustment is unpredictable and uncertain. At the same time, process adjustment will disrupt the overall process environment of the kiln, and the kiln process cannot be fully restored after the material mountain stabilizes. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the present invention aims to provide a multi-stage diversion feeding system and method for high-generation substrate glass furnaces. The present invention realizes the visual monitoring and stability adjustment of the furnace material pile state, improves the automation level of the substrate glass production line, and effectively prevents problems such as material pile collapse and deviation caused by material pile instability.

[0006] To achieve the above objectives, the present invention employs the following technical solution:

[0007] This invention discloses a multi-stage diversion feeding system for a high-generation substrate glass furnace, including a first silo, which is connected to several first spiral feeders. The outlet of the first spiral feeders is connected to a second silo, which is connected to the furnace inlet via a second spiral feeder. A diversion device is provided at the furnace inlet, and an industrial television is arranged inside the furnace.

[0008] Furthermore, the first screw feeder includes a first screw shaft, the input end of which is connected to the output end of a first drive motor via a transmission device.

[0009] Furthermore, the second screw feeder includes a second screw shaft, the input end of which is connected to the output end of a second drive motor via a transmission device.

[0010] Furthermore, a first stepper motor is arranged on the second screw feeder. The first stepper motor is connected to the second screw shaft through a transmission device. The first stepper motor is used to realize the horizontal movement of the second screw shaft perpendicular to the second screw shaft.

[0011] Furthermore, the diversion device includes a feeding diversion plate, which is installed at the kiln inlet via a diversion shaft.

[0012] Furthermore, the feeding diversion plate is connected to a second stepper motor via a transmission device, and the second stepper motor controls the rotation angle of the feeding diversion plate via the transmission device.

[0013] Furthermore, the rotation angle of the feeding diversion plate is from 0° to 45°.

[0014] Furthermore, the kiln inlet is located on the front wall of the kiln, the thickness of the front wall of the kiln is equal to the length of the feeding diversion plate, and the height of the feeding diversion plate is less than the inner diameter of the outlet of the second screw feeder.

[0015] Based on the above structure, the present invention also discloses a working method for a multi-stage diversion feeding system for a high-generation substrate glass furnace, comprising the following steps:

[0016] Glass powder is fed into the first silo and then enters the kiln through the first screw feeder, the second silo, the second screw feeder, and the kiln inlet.

[0017] Real-time images of the material pile inside the kiln are obtained through industrial television to monitor whether the condition of the material pile is stable.

[0018] If the material pile exhibits an uneven distribution of material, the conveying rate from the first silo to the second silo is adjusted using the first and second screw feeders, thereby adjusting the size of the material pile until it falls within the threshold range.

[0019] If the material pile is not symmetrical, the discharge volume on the left and right sides of the kiln inlet is adjusted by the diversion device until the material pile is symmetrical.

[0020] Furthermore, if the material pile is asymmetrical, the discharge volume on the left and right sides of the kiln inlet is adjusted by the diversion device, and the horizontal position of the second spiral shaft is adjusted simultaneously by the first stepper motor.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] This invention includes a first silo for feeding glass powder. The first silo is connected to several first screw feeders, the outlets of which are connected to a second silo. The second silo is connected to the kiln inlet via a second screw feeder. Through a multi-stage silo and multi-stage glass powder diversion design, the feeding amount at different feed ports can be adjusted, ensuring the consistency of the powder pile size at different feed ports within the kiln. A diversion device is installed at the kiln inlet, allowing adjustment of the glass powder conveying amount on the left and right sides of the kiln inlet, achieving symmetrical adjustment of a single powder pile. An industrial television is installed inside the kiln. Real-time images of the powder pile inside the kiln are acquired through the industrial television. Machine vision algorithms are used to calculate the characteristic values ​​of the powder pile, thereby determining its state. Finally, the multi-stage diversion feeding system in the kiln achieves consistency across different powder piles and symmetrical adjustment of a single powder pile. This invention enables visualized monitoring and stability adjustment of the kiln material pile state, improves the automation level of the substrate glass production line, and effectively prevents problems such as material pile collapse and deviation caused by material pile instability.

[0023] This invention involves feeding glass powder into a first silo. The glass powder then enters the kiln through a first screw feeder, a second silo, a second screw feeder, and the kiln inlet. The multi-stage silo and multi-stage glass powder diversion design allows for adjustment of the feed rate at different inlets, ensuring consistency in the size of the powder piles at different inlets within the kiln. Real-time images of the powder piles inside the kiln are acquired via industrial television to monitor their stability. Finally, the multi-stage diversion feeding system in the kiln achieves consistency across different powder piles and adjusts the symmetry of individual piles. If uneven powder piles occur, the feed rate from the first silo to the second silo is adjusted using the first and second screw feeders, thereby adjusting the pile size until it falls within a threshold range. If the powder piles are asymmetrical, the discharge rate on both sides of the kiln inlet is adjusted using the diversion device until the piles are symmetrical. This invention enables visualized monitoring and stability adjustment of the kiln material pile state, improves the automation level of the substrate glass production line, and effectively prevents problems such as material pile collapse and deviation caused by material pile instability.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings:

[0031] See Figure 1This invention discloses a multi-stage diversion feeding system for a high-generation substrate glass furnace, comprising a first silo 3 for feeding glass powder. The first silo 3 is connected to several first spiral feeders 5, the outlets of which are connected to a second silo 4. The second silo 4 is connected to the furnace inlet via a second spiral feeder 6. Through the multi-stage silo and multi-stage glass powder diversion design, the feeding amount at different feeding ports can be adjusted, ensuring the consistency of the material pile size at different feeding ports within the furnace. A diversion device 2 is provided at the furnace inlet, which can adjust the glass powder conveying amount on the left and right sides of the furnace inlet, achieving symmetrical adjustment of a single material pile, thereby maintaining the stability of the material pile, ensuring stable melting of the glass powder, guaranteeing the stability of the furnace pressure and liquid level, reducing substrate glass defects, and extending the furnace service life. An industrial television 17 is arranged inside the furnace. This invention acquires real-time images of the material pile inside the kiln using industrial television, calculates characteristic values ​​of the material pile using machine vision algorithms, and then determines the state of the material pile. Finally, a multi-stage diversion feeding system in the kiln is used to adjust the consistency of different material piles and the symmetry of a single material pile. This invention achieves visualized monitoring and stability adjustment of the kiln material pile state, improves the automation level of the substrate glass production line, and effectively prevents problems such as material pile collapse and deviation caused by material pile instability.

[0032] See Figure 1 In another feasible embodiment of the present invention, the following modifications are made as appropriate. It includes a first silo 3, which is connected to a plurality of first screw feeders 5. The outlets of the first screw feeders 5 are connected to a second silo 4. The second silo 4 is connected to the inlet of a kiln via a second screw feeder 6. A diversion device 2 is provided at the kiln inlet, and an industrial television 17 is arranged inside the kiln.

[0033] In practical use, glass powder is fed into the first silo 3, and then enters the kiln through the first screw feeder 5, the second silo 4, the second screw feeder 6, and the kiln inlet. The multi-stage silo and multi-stage glass powder diversion design allows for adjustment of the feeding amount at different feeding ports, ensuring consistency in the size of the material piles at different feeding ports within the kiln. Real-time images of the material piles 16 inside the kiln are acquired via industrial television 17 to monitor their stability. The real-time images of the material piles inside the kiln are obtained via industrial television, and machine vision algorithms are used to calculate the characteristic values ​​of the material piles, thereby determining their state. Finally, the kiln's multi-stage diversion feeding system achieves consistency adjustment between different material piles and symmetry adjustment for a single material pile. The conveying amount from the first silo 3 to the second silo 4 is adjusted via the first screw feeder 5 and the second screw feeder 6, thereby adjusting the size of the material pile until it falls within a threshold range. The discharge amount on both sides of the kiln inlet is adjusted via the diversion device 2 until the material piles are symmetrical.

[0034] Example 1:

[0035] See Figure 1 This embodiment discloses a multi-stage diversion feeding system for a high-generation substrate glass furnace, including a first silo 3, the first silo 3 being connected to a plurality of first spiral feeders 5, the outlet of the first spiral feeders 5 being connected to a second silo 4, the second silo 4 being connected to the furnace inlet through a second spiral feeder 6, a diversion device 2 being provided at the furnace inlet, and an industrial television 17 being arranged inside the furnace.

[0036] The first spiral feeder 5 includes a first spiral shaft 7. The input end of the first spiral shaft 7 is connected to the output end of the first drive motor 9 through a transmission device. The first drive motor 9 is used to adjust the rotational speed of the first spiral shaft 7, thereby adjusting the conveying speed of the first spiral feeder 5.

[0037] The second screw feeder 6 includes a second screw shaft 8, the input end of which is connected to the output end of a second drive motor 10 via a transmission device. The second drive motor 10 is used to adjust the rotational speed of the second screw shaft 8, thereby adjusting the conveying speed of the second screw feeder 6.

[0038] The first spiral feeder 5, in conjunction with the second spiral feeder 6, adjusts the amount of material fed through different feed ports, ensuring the consistency of the size of the material pile at different feed ports in the kiln.

[0039] The second spiral feeder 6 is equipped with a first stepper motor 11, which is connected to the second spiral shaft 8 through a transmission device. The first stepper motor 11 is used to realize the horizontal movement of the second spiral shaft 8 perpendicular to the second spiral shaft 8, thereby realizing the adjustment of the amount of glass powder conveyed on the left and right sides of the second spiral shaft, and thus realizing the symmetry adjustment of a single material pile.

[0040] Example 2:

[0041] See Figure 1 This embodiment discloses a multi-stage diversion feeding system for a high-generation substrate glass furnace, including a first silo 3, the first silo 3 being connected to a plurality of first spiral feeders 5, the outlet of the first spiral feeders 5 being connected to a second silo 4, the second silo 4 being connected to the furnace inlet through a second spiral feeder 6, a diversion device 2 being provided at the furnace inlet, and an industrial television 17 being arranged inside the furnace.

[0042] The diversion device 2 includes a feeding diversion plate 12, which is installed at the kiln inlet via a diversion shaft 13.

[0043] The feeding diversion plate 12 is connected to the second stepper motor 14 through a transmission device, and the second stepper motor 14 controls the rotation angle of the feeding diversion plate 12 through the transmission device.

[0044] The material feeding diversion plate 12 can rotate from 0° to 45°.

[0045] The kiln inlet is located on the front wall 15 of the kiln. The thickness of the front wall 15 is equal to the length of the feeding diversion plate 12, and the height of the feeding diversion plate 12 is less than the inner diameter of the outlet of the second screw feeder 6.

[0046] The rotation angle of the feeding diversion plate 12 is adjusted by the second stepper motor 14, thereby adjusting the amount of glass powder on the left and right sides of the kiln inlet, thus achieving symmetrical adjustment of the single material pile.

[0047] Example 3:

[0048] See Figure 1 and Figure 2 This embodiment discloses a multi-stage diversion feeding system for high-generation substrate glass furnaces, including a feeding device 1 and a diversion device 2. The feeding device 1 includes a first hopper 3 and a second hopper 4, with a first spiral feeder 5 connected between the first hopper 3 and the second hopper 4, and the second hopper 4 connected to a second spiral feeder 6. The diversion device 2 is connected to the second spiral feeder 6 and includes a feeding diversion plate 12 and a diversion shaft 13.

[0049] The second hopper 4 includes a left second hopper 4-1 and a right second hopper 4-2, which are connected to the first hopper 3 through the left first screw feeder 5-1 and the right first screw feeder 5-2, respectively.

[0050] The input ends of the left first spiral feeder 5-1 and the right first spiral feeder 5-2 are respectively connected to the output ends of the two first drive motors 9. By adjusting the frequency of the two first drive motors 9 differently, the two first spiral shafts 7 are rotated differently, thereby realizing the differentiated conveying of glass powder from the first silo 3 to the left second silo 4-1 and the right second silo 4-2.

[0051] The second spiral shaft 8 is connected to the output end of the first stepper motor 11, which enables the second spiral shaft 8 to move left and right at the axis position, thereby adjusting the amount of glass powder conveyed on the left and right sides of the second spiral shaft 8.

[0052] The second spiral shaft 8 is moved on one side of the axis by the first stepper motor 11, and the distance is divided into 0 to 6 levels, with each level moving a distance of 0 mm to 5 mm.

[0053] The diversion device 2 includes a feeding diversion plate 12 and a diversion shaft 13. The feeding diversion plate 12 can rotate around the diversion shaft 13, and the feeding diversion plate 12 is connected to the output end of the second stepper motor 14. Under the drive of the second stepper motor 14, the feeding diversion plate 12 can rotate at multiple angles to the left and right, thereby realizing the left and right diversion feeding of glass powder.

[0054] The length of the feeding diversion plate 12 is the same as the thickness of the kiln front wall 15, and the length is 450mm to 550mm.

[0055] The height of the feeding diversion plate 12 is slightly smaller than the inner diameter of the second screw feeder 6;

[0056] The feeding diversion plate 12 has a rotation angle of 0° to 45°. The rotation angle of the feeding diversion plate 12 is divided into 0 to 9 levels by the second stepper motor 14.

[0057] The multi-stage diversion feeding system of the present invention, through multi-stage silos and multi-stage glass powder diversion design, can adjust the feeding amount at different feeding ports, ensuring the consistency of the size of the material pile at different feeding ports in the kiln; at the same time, the second spiral shaft of the second spiral feeder can move left and right at the axis position, which can adjust the amount of glass powder conveyed on the left and right sides of the second spiral shaft. Combined with the diversion device, it can further realize the symmetrical adjustment of a single material pile, thereby maintaining the stability of the material pile, realizing the stable melting of glass powder, ensuring the stability of kiln pressure and liquid level, reducing defects in substrate glass, and extending the service life of the kiln.

[0058] Based on the above structure, this invention discloses a working method for a multi-stage diversion feeding system in a high-generation substrate glass furnace. (See also...) Figure 3 This includes the following steps:

[0059] S1. Glass powder is fed into the kiln through the first hopper 3. The glass powder enters the kiln through the first screw feeder 5, the second hopper 4, the second screw feeder 6 and the kiln inlet.

[0060] S2. Acquire real-time images of the material pile inside the kiln 16 via industrial television 17 to monitor whether the material pile 16 is stable.

[0061] S3. If the material pile in the material mountain 16 exhibits a large and small pile phenomenon, the conveying amount from the first hopper 3 to the second hopper 4 is adjusted by the first screw feeder 5 and the second screw feeder 6, thereby adjusting the size of the material pile until the material pile is within the threshold range.

[0062] S4. If the material pile 16 is not symmetrical, adjust the discharge volume on the left and right sides of the kiln inlet through the diversion device 2 until the material pile is symmetrical.

[0063] See Figure 3In another feasible embodiment of the present invention, the following modifications are made as appropriate. Glass powder is fed into the kiln through the first silo 3, and then enters the kiln through the first screw feeder 5, the second silo 4, the second screw feeder 6, and the kiln inlet. The multi-stage silo and multi-stage glass powder diversion design allows for adjustment of the feeding amount at different feeding ports, ensuring consistency in the size of the material piles at different feeding ports within the kiln. Real-time images of the material piles 16 inside the kiln are acquired via an industrial television 17 to monitor their stability. The machine vision algorithm calculates the characteristic values ​​of the material piles to determine their state. Finally, the multi-stage diversion feeding system of the kiln achieves consistency adjustment between different material piles and symmetry adjustment of a single material pile. If the material pile in the sump 16 exhibits uneven size, the conveying rate from the first hopper 3 to the second hopper 4 is adjusted via the first screw feeder 5 and the second screw feeder 6, thereby adjusting the size of the material pile until it falls within a threshold range. If the material pile in the sump 16 is asymmetrical, the discharge rate on both sides of the kiln inlet is adjusted via the diversion device 2 until the material pile is symmetrical. This invention enables visualized monitoring and stability adjustment of the kiln material pile status, improves the automation level of the substrate glass production line, and effectively prevents problems such as material pile collapse and deviation caused by material pile instability.

[0064] Example 4:

[0065] See Figure 3 This embodiment discloses a working method for a multi-stage feed system for high-generation substrate glass furnaces, including the following steps:

[0066] S1. Glass powder is fed into the kiln through the first hopper 3. The glass powder enters the kiln through the first screw feeder 5, the second hopper 4, the second screw feeder 6 and the kiln inlet.

[0067] S2. Acquire real-time images of the material pile inside the kiln 16 via industrial television 17 to monitor whether the material pile 16 is stable.

[0068] S3. If the material pile in the material mountain 16 exhibits a large and small pile phenomenon, the conveying amount from the first hopper 3 to the second hopper 4 is adjusted by the first screw feeder 5 and the second screw feeder 6, thereby adjusting the size of the material pile until the material pile is within the threshold range.

[0069] S4. If the material pile 16 is not symmetrical, adjust the discharge volume on the left and right sides of the kiln inlet through the diversion device 2 until the material pile is symmetrical.

[0070] If the material pile 16 is not symmetrical, the discharge volume on the left and right sides of the kiln inlet is adjusted by the diversion device 2, and the horizontal position of the second spiral shaft 8 is adjusted simultaneously by the first stepper motor 11.

[0071] Example 5:

[0072] This embodiment discloses a working method for a multi-stage feed system for high-generation substrate glass furnaces, including the following steps:

[0073] Step 1: Acquire real-time images of the material pile 16 inside the kiln using the kiln industrial television 17, and calculate the feature values ​​of the material pile 16 using machine vision algorithms;

[0074] Step 2: Set the characteristic value threshold of material pile 16 to determine whether the state of material pile 16 is stable, that is, whether there are phenomena such as large and small material piles and material pile symmetry.

[0075] Step 3: Based on the judgment results of the state of material pile 16, adjust the state of material pile 16 by adjusting the multi-stage diversion feeding system of the kiln;

[0076] Step 4: Repeat Step 1 to calculate the adjusted characteristic value of the material pile 16 and determine whether the state of the material pile 16 is stable.

[0077] The characteristic values ​​of the material pile 16 include the width W of the material pile edge from the center of the feeding port and the height H of the material pile.

[0078] The width W of the material pile edge from the center of the feed inlet can be used to determine the symmetry of the material pile melting, as detailed below:

[0079] If the distance W from the center of the feeding port on the left edge of the material pile 16 is less than the threshold, it indicates that there is less glass powder on the left side of the material pile 16. In this case, the second spiral shaft 8 of the second spiral feeder 6 is moved to the right of the axis position by the first stepper motor 11, thereby adjusting the amount of glass powder conveyed on both sides of the second spiral shaft, i.e., the amount of powder conveyed on the left side is greater than the amount of powder conveyed on the right side. At the same time, the angle of the feeding diversion plate 12 is adjusted to the right by the second stepper motor 14 to adjust the flow of powder, i.e., the amount of powder fed on the left side of the material pile is greater than the amount of powder fed on the right side, thus completing the symmetry adjustment of the material pile 16. If the distance W from the center of the feeding port on the left edge of the material pile 16 is less than the threshold, the second spiral shaft 8 of the second spiral feeder 6 and the feeding diversion plate 12 are adjusted in the opposite direction, thereby achieving the symmetry adjustment of the material pile 16. If the distance W from the center of the feeding port on the left edge of the material pile 16 is equal to the threshold, no adjustment is made.

[0080] Conversely, based on the comparison between the distance W from the right edge of the material pile 16 to the center of the feeding port and the threshold, the left material pile is adjusted using the same adjustment method as the right side of the material pile 16.

[0081] The height H of the stockpile can be used to determine the consistency of different stockpiles, as detailed below:

[0082] If the characteristic height H of the material pile 16 is less than or equal to the set threshold, the characteristic height H of the material pile 16 is restored by increasing the rotation speed of the first screw shaft 7 and the second screw shaft 8 of the first screw feeder 5 and the second screw feeder 6; otherwise, no adjustment is made.

[0083] If the characteristic height H values ​​of the left material pile 16-1 and the right material pile 16-2 are different, it indicates that there is an inconsistency between the left and right material piles. In this case, the consistency adjustment of the left and right material piles can be achieved by differentially increasing or decreasing the rotation speed of the first spiral feeder 5 and the first spiral shaft 7 and the second spiral shaft 8 of the second spiral feeder 6.

[0084] The multi-stage diversion kiln feeding method of this invention is based on real-time images of the material pile inside the kiln obtained by industrial television. The characteristic values ​​of the material pile are calculated by machine vision algorithm to determine the state of the material pile. Finally, the consistency of different material piles and the symmetry of a single material pile are adjusted through the multi-stage diversion feeding system of the kiln. This method realizes the visual monitoring and stability adjustment of the state of the kiln material pile, improves the automation level of the substrate glass production line, and effectively prevents problems such as material pile collapse and deviation caused by material pile instability.
