Description

Furthermore, this invention also relates to a glass melting furnace having an online automatic cleaning structure for industrial televisions. Background Technology

[0002] A glass melting furnace is a high-temperature, high-voltage, enclosed melting furnace. To facilitate observation of the furnace's internal conditions during production, such as the material pile, the molten glass level, and the furnace top, an industrial television needs to be installed on the furnace body to monitor changes in the furnace environment during production. However, due to the volatilization of the glass raw materials and the furnace body, as well as the corrosive effects of the liquid, the industrial television lens may become blurry, rendering the television unusable.

[0003] The existing method requires periodically removing the industrial television, manually cleaning it, and then reinstalling it before it can be used normally.

[0004] Because the industrial TV is installed on top of the furnace and is in a high-temperature, high-voltage environment, this method of handling is not only time-consuming and labor-intensive and difficult to clean, but also causes the glass melting furnace to become unsealed after the industrial TV is removed, resulting in unstable parameters such as furnace pressure, temperature and glass flow rate in the production line, which in turn affects normal production and causes unstable product quality.

[0035] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0036] Reference Figure 1 and Figure 2A preferred embodiment of the present invention provides an online automatic cleaning industrial television structure, comprising: a mounting brick assembly 10 for mounting in an installation opening in the furnace body of a melting furnace; the mounting brick assembly 10 having an installation channel connecting the inner and outer sides of the furnace body; an industrial television 20 arranged along the length of the installation channel for personnel outside the furnace to observe the conditions inside the furnace through the industrial television 20; a cooling cleaning device fitted along the length of the installation channel onto the outer circumference of the industrial television 20; the cooling cleaning device having a flushing water path 3 and a cooling water path 5; the flushing water path 3 being connected to a flushing control circuit, so that external flushing water is pumped into the flushing water path 3 under the action of the flushing control circuit to flush the observation lens embedded in the industrial television 20, and the flushed wastewater is discharged out of the cooling cleaning device; the cooling water path 5 being connected to a cooling control circuit, so that external cooling water is pumped into the cooling water path 5 under the action of the cooling control circuit to cool the industrial television 20 and the cooling cleaning device, and the cooled return water is discharged out of the cooling cleaning device.

[0037] In the online automatic cleaning industrial television structure of the present invention, the flushing control loop includes at least a flushing water supply device for supplying flushing water, a wastewater collection device for holding wastewater, a pipeline connecting the flushing water path to the flushing water supply device and the wastewater collection device, a flushing pump and a switching valve installed in the pipeline, a detection device and a controller connected to the industrial television 20 for analyzing the clarity of the television picture, and the flushing pump, the switching valve and the detection device are respectively connected to the controller; similarly, the cooling control loop includes at least a cooling water supply device for supplying cooling water, a cooling water collection device for holding the returned cooling water, a pipeline connecting the cooling water path to the cooling water supply device and the cooling water collection device, a cooling pump and a switching valve installed in the pipeline and a controller, and the pumping component and the switching valve are respectively connected to the controller.

[0038] During operation, the detection device analyzes the clarity of the industrial television image and feeds the results back to the controller. Once the detection results meet the cleaning conditions, the controller opens the valve on the pipeline. Alternatively, if no detection device is installed, the controller opens the valve at set time intervals or upon receiving instructions from external personnel. Simultaneously, the flushing pump operates, allowing the cleaning fluid in the flushing water supply device to enter the flushing water path and forming a high-pressure water jet at the embedded end of the industrial television 20 to flush the viewing lens. The flushed wastewater then flows through the flushing water path and external pipeline to the wastewater collection device. After cleaning, the controller closes the valve and the cleaning pump, thus completing the online automatic cleaning process of the industrial television lens. Similarly, due to the high ambient temperature of the industrial television 20, in order to meet the cooling and cleaning requirements of the industrial television 20, it is cooled 24 hours a day during the production process. The controller can also open the switch valve on the pipeline according to the set time interval or under the instruction sent by external personnel. At the same time, the cooling pump works, so that the cooling water in the cooling water supply device enters the cooling water circuit to cool the industrial television 20 and the cooling cleaning device respectively. The cooled water then flows from the cooling water circuit and the external pipeline to the cooling water collection device, thereby realizing the online automatic cooling of the industrial television 20 and the cooling cleaning device.

[0039] The online automatic cleaning system for industrial television structures of this invention requires no manual intervention during the entire process, achieving a high degree of automation, thus saving time and labor. The cleaning and cooling operations are simple, improving cleaning efficiency. On the other hand, since the melting furnace is completely sealed throughout the entire cleaning and cooling process, it will not affect the furnace pressure, ensuring the stability of parameters such as furnace pressure, temperature, and glass flow rate in the production line, thereby guaranteeing normal production and product quality stability.

[0040] Optionally, in this invention, heat insulation cotton is provided at the contact points between the cooling cleaning device and the installation channel to reduce heat transfer between the installation brick group 10 and the cooling cleaning device.

[0041] Optionally, such as Figures 2-5 As shown, the mounting brick assembly 10 includes a lower support brick 11 fixed to the furnace body brick in the mounting opening on the furnace body, a mounting brick 12 limited on the lower support brick 11, and an upper support brick 13 limited on the mounting brick 12. The structure is simple and easy to implement.

[0042] In this optional solution, such as Figure 3As shown, the top of the lower support brick 11 is recessed to form a first limiting step 111, and the inner sidewall of the lower support brick 11 is inclined towards the first limiting step 111 to form a guide slope 112, and the mounting brick 12 is fixedly supported on the first limiting step 111. In a specific embodiment of this optional scheme, the material of the lower support brick 11 is a brick material with high temperature and pressure resistance and high insulation performance; the guide slope 112 ensures that the lower support brick 11 does not obstruct the view of the industrial television 20, and also prevents solid dust from accumulating on it; preferably, the angle of the guide slope 112 is best between 20° and 45°; the first limiting step 111 is used for positioning and installing the mounting brick 12 to ensure reliable installation of the mounting brick 12; the length of the lower support brick 11 is 250-400mm, the width is 400-650mm, and the thickness is 100-200mm, with the thinnest part after processing not less than 50mm to avoid breakage during installation.

[0043] In this optional solution, such as Figure 4 As shown, the outer wall of the mounting brick 12 is provided with an inclined positioning slope 121 to limit the installation angle of the industrial television 20. The mounting channel is perpendicular to the positioning slope 121 and penetrates the mounting brick 12. In a specific embodiment of this optional solution, the mounting brick 12 is composed of two bricks that are completely symmetrical from left to right. The mounting channel is set at the joint of the two bricks, which facilitates the processing and setting of the mounting channel. The material of the mounting brick 12 is a brick material that is resistant to high temperature and high pressure and has high insulation performance. The positioning slope 121 determines the installation angle of the industrial television 20. To ensure the observation line and the thickness of the brick, the angle between the positioning slope 121 and the vertical direction is 10° to 25°.

[0044] Preferably, such as Figure 4 As shown, the installation channel includes a straight inclined hole 122 extending inward from a vertical positioning bevel 121, a rhomboid hole 123 located below and communicating with the straight inclined hole 122, and a conical hole 124 extending concavely from the inner sidewall of the mounting brick 12 and forming a cone shape. The industrial television 20 is located within the straight inclined hole 122, and a cooling and cleaning device is installed in the straight inclined hole 122 and the rhomboid hole 123. The constricted end of the conical hole 124 is coaxially connected to the straight inclined hole 122. In this preferred embodiment, to reduce the heat radiation from the high temperature inside the melting furnace to the industrial television 20 while meeting the line-of-sight requirements, the depth of the straight hole is approximately half the thickness of the brick, preferably 100-200 mm; the conical hole 124 is used to ensure the line-of-sight of the industrial television 20, and the thinnest edge thickness of the mounting brick 12 after processing is required to be greater than 15 mm.

[0045] In this optional solution, such as Figure 5As shown, the bottom of the upper support brick 13 is concave to form an inclined second limiting step 131, which is used to level the top of the mounting brick assembly 10, facilitating connection with the bricks in the mounting opening. The upper support brick 13 is limited and supported on the top of the mounting brick 12 by the second limiting step 131. In a specific embodiment of this optional solution, the inclined surface of the inclined second limiting step 131 ensures that the top of the upper support brick 13 is horizontal, and the second limiting step 131 is used to prevent the upper support brick 13 from moving into the furnace. The thinnest part of the upper support brick 13 after processing is not less than 30mm.

[0046] Optionally, such as Figure 6 As shown, the cooling cleaning device includes a flushing water channel cylinder 30, a wastewater collection component 40, and a cooling water channel cylinder 50 for assembling to form a cooling water channel 5. The flushing water channel cylinder 30 is a hollow cylinder, inserted into a straight inclined hole 122 from the positioning inclined surface 121 side. The wastewater collection component 40 is installed in a square inclined hole 123, and the inner end of the flushing water channel cylinder 30 communicates with the wastewater collection component 40 to form the flushing water channel 3. The cooling water channel cylinder 50 is a hollow cylinder, inserted into the inner channel of the flushing water channel cylinder 30 from the positioning inclined surface 121 side, and the industrial television 20 is axially installed in the inner channel of the cooling water channel cylinder 50. In this optional solution, such as... Figure 6 As shown, the components of the flushing water channel cylinder 30, the wastewater collection component 40, and the cooling water channel cylinder 50 are manufactured separately and then welded together. The material is high-temperature resistant stainless steel with a thickness of 0.5 to 2 mm.

[0047] In this optional solution, such as Figure 8 As shown, the flushing water circuit component 30 includes a first annular disk 31 with an inner annular cavity, a first cylindrical column 32 with an inner cylindrical cavity, and a first water inlet pipe 33 for communication with the flushing control circuit. The connecting end of the first cylindrical column 32 is fixed to the first side end of the first annular disk 31. The inner end of the first cylindrical column 32 is provided with an annular flushing ring port 320 that communicates with its inner cylindrical cavity. The first water inlet pipe 33 communicates with the second side end of the first annular disk 31. After the first cylindrical column 32 is inserted into the inclined straight hole 122 from the positioning inclined surface 121, the first side end of the first annular disk 31 abuts against the positioning inclined surface 121 for limitation. The inner annular hole of the first annular disk 31 and the inner shaft hole of the first cylindrical column 32 communicate to form an inner channel for installing the cooling water circuit component 50. The first water inlet pipe 33, the inner annular cavity of the first annular disk 31, and the inner cylindrical cavity of the first cylindrical column 32 communicate to form part of the structure of the flushing water circuit 3.

[0048] Preferably, such as Figure 9As shown, the first cylindrical column 32 includes an inner cylindrical body 321 and an outer cylindrical body 322 that are fitted together, and a heat-conducting plate 323 connected between the inner cylindrical body 321 and the outer cylindrical body 322 for heat conduction. In this preferred embodiment, the heat-conducting plates 323 are evenly spaced along the circumference of the first cylindrical column 32, and each heat-conducting plate 323 extends along the axial direction of the first cylindrical column 32, for transferring energy from the cooling water channel 5 to cool the flushing water channel cylinder 30 when the flushing water channel is not working. Preferably, as shown... Figure 9 As shown, the inner end of the inner cylinder 321 is folded inward to form an end plate 3210, and the inner end of the outer cylinder 322 is folded inward to form a cone 3220. The axial gap between the cone 3220 and the end plate 3210 forms a flushing annulus 320. In this preferred embodiment, to ensure the flushing water pressure, the minimum axial distance of the flushing annulus 320 is typically set to 0.2–1 mm.

[0049] At work, such as Figure 11 As shown, the automatic online cleaning method is as follows: The detection device analyzes the clarity of the industrial television 20 image. Once the cleaning conditions are met, the controller opens the switch valve on the control pipeline, and the cleaning pump operates to allow the cleaning fluid to enter from the inlet of the first water inlet pipe 33. A high-pressure water jet is formed at the flushing ring 320 at the embedded end of the industrial television 20 to rinse the viewing lens. After rinsing, the wastewater flows into the wastewater collection component 40 and finally flows out into the wastewater collection device. After cleaning, the controller closes the switch valve on the control pipeline and the cleaning pump, thus completing the online automatic cleaning of the industrial television lens. The entire process requires no manual intervention, improving cleaning efficiency. Furthermore, since the melting furnace is completely sealed throughout the process, it does not affect the furnace pressure, ensuring the stability of product quality.

[0050] In this optional solution, such as Figure 7As shown, the wastewater collection component 40 includes a wastewater collection tank 41 for collecting falling wastewater and a first outlet pipe 42 for discharging wastewater from the wastewater collection tank 41 outwards. The wastewater collection tank 41 is disposed within the rhomboid hole 123 and communicates with the downward-sloping inner end of the first cylindrical column 32. The first outlet pipe 42 is located within the rhomboid hole 123, with one end communicating with the wastewater collection tank 41, and the opposite end extending outwards along the rhomboid hole 123 and connecting to the flushing control circuit. The first inlet pipe 33, the inner annular cavity of the first annular disc 31, the inner cylindrical cavity of the first cylindrical column 32, the wastewater collection tank 41, and the first outlet pipe 42 are connected to form the flushing water path 3. In a specific embodiment of this optional solution, the wastewater collection tank 41 is square, which facilitates installation inside the mounting bricks. Its upper edge has an irregular shape to match the flushing water channel cylinder 30, ensuring that the view of the industrial television is not obstructed and preventing wastewater from splashing out. The front end of the wastewater collection tank 41 needs to extend 10-40mm beyond the first cylindrical column. The first water outlet pipe 42 has a downward angle to ensure that the water can be completely discharged. The first water outlet pipe 42 needs to be welded to the notch of the first annular disc 31, and the cooling water channel conducts heat to keep it at a constant temperature to prevent it from overheating and deforming or being damaged.

[0051] In this optional solution, such as Figure 10 As shown, the cooling water channel cylinder 50 includes a second annular disk 51 with an inner annular cavity, a second cylindrical column 52 with an inner cylindrical cavity, and a second inlet pipe 53 and a second outlet pipe 54 for connecting to the cooling control circuit, respectively. The connecting end of the second cylindrical column 52 is fixed to the second side end of the second annular disk 51. The inner cylindrical cavity of the second cylindrical column 52 is closed at its inner end. The second inlet pipe 53 and the second outlet pipe 54 are respectively connected to the second side end of the second annular disk 51. After the second cylindrical column 52 is inserted into the inner channel of the flushing water channel cylinder 30 from the positioning inclined surface 121 side, the second side end of the second annular disk 51 abuts against the outer end of the flushing water channel cylinder 30 for limitation. The inner annular hole of the second annular disk 51 and the inner shaft hole of the second cylindrical column 52 are connected to form an inner channel for installing the industrial television 20. The second inlet pipe 53, the inner annular cavity of the second annular disk 51, the inner cylindrical cavity of the second cylindrical column 52, and the second outlet pipe 54 are connected to form the cooling water channel 5.

[0052] Preferably, such as Figure 10As shown, the inner annular cavity of the second annular disk 51 is also provided with a first guide plate 55 to divide the inner annular cavity into two separated semi-annular cavities, and the second water inlet pipe 53 and the second water outlet pipe 54 are respectively connected to the two semi-annular cavities. The inner cylinder cavity of the second cylindrical column 52 is also provided with two opposing second guide plates 56. One end of the two second guide plates 56 is aligned with the connecting end of the second cylindrical column 52, and their opposing second ends extend toward the embedded end of the second cylindrical column 52 to divide the inner cylinder cavity into two semi-cylindrical cavities that are only connected to the embedded end of the second cylindrical column 52, and the two semi-cylindrical cavities are respectively connected to the two semi-annular cavities. The arrangement of the first guide plate 55 and the second guide plate 56 ensures that the cooling water enters from one side and exits from the other side, thereby ensuring the cooling effect of the industrial television 20. The front end of the second guide plate 56 is 30-50mm away from the embedded end of the second cylindrical column 52.

[0053] At work, such as Figure 12 As shown, complete the installation according to the industrial television lens installation diagram to ensure that the industrial television can meet the observation requirements of the melting furnace. Since the ambient temperature of the industrial television is high, in order to meet the cooling and cleaning requirements of the industrial television, cooling water is circulated in the cooling water cylinder 50 for 24 hours during the production process to achieve the purpose of cooling the industrial television. The cooling water is preferably industrial pure water with a resistance value of not less than 2MΩ*cm.

[0054] Reference Figure 1 and Figure 2 A preferred embodiment of the present invention provides a glass melting furnace, comprising: a melting furnace body, wherein the melting furnace body has an installation port, and the installation port is provided with an online automatic cleaning industrial television structure as described above. Thus, the glass melting furnace of the present invention has a high degree of automation, saves time and labor, and simplifies cleaning and cooling operations, thereby improving cleaning efficiency. On the other hand, since the melting furnace is completely sealed throughout the entire cleaning and cooling process, it will not affect the furnace pressure, ensuring the stability of parameters such as furnace pressure, temperature, and glass flow rate in the production line, thereby ensuring normal production and product quality stability.
