A plurality of second air outlets 222 and a plurality of third air outlets 223 are respectively provided at both sides of the first air outlet 221 along the longitudinal direction of the main duct 210. The second air outlet 222 is used for performing air blast cooling on the area, close to the pool wall brick joint 320, of the first corner brick 311, and the third air outlet 223 is used for performing air blast cooling on the area, close to the pool wall brick joint 320, of the second corner brick 312. The distance between the second air outlet nozzle 222 and the first air outlet nozzle 221 is equal to the distance between the third air outlet nozzle 223 and the first air outlet nozzle 221, and the second air outlet nozzle 222 and the third air outlet nozzle 223 are both arranged at the positions of the corner bricks 310, which are close to the tank wall brick joints 320, so that the areas, which are easy to erode, of the first corner bricks 311 and the second corner bricks 312 can be cooled in a targeted manner.

Referring to fig. 3, in the longitudinal direction of the main air duct 210, the air outlet of the uppermost air outlet of the plurality of third air outlets 223 is inclined downward by a set angle, so as to avoid that the cooling air blown out from the uppermost air outlet enters the space region containing the high-temperature molten glass in the kiln body 300 from the upper edge position of the corner brick 310, and influences the melting temperature of the space region. The downward inclination is set at an angle of 30-60 deg.. Similarly, the air outlet of the uppermost air outlet of the plurality of first air outlets 221 and the air outlet of the uppermost air outlet of the plurality of second air outlets 222 are respectively inclined downwards by a set angle.

Referring to fig. 3, an air volume adjusting device 230 is disposed at the air inlet of the main air duct 210 for adjusting the air volume entering the main air duct 210. In other embodiments, an air guiding duct 240 may be further provided to convey the cooling air into the main air duct 210, and at this time, the air volume adjusting device 230 may be disposed at an outlet position of the air guiding duct 240, and the disposed position of the air volume adjusting device 230 is not limited, so long as the air volume of the cooling air blown out by the air outlet 220 is adjusted.
The air outlet 220 is made of heat-resistant stainless steel, or other high-temperature-resistant materials. The main air duct 210 is made of heat-resistant stainless steel, or other heat-resistant materials. In other embodiments, the main plenum 210 may be an oval cylindrical structure or other suitable shape.
In order to be able to automatically regulate the influencing factors of the cooling system 200, the cooling system 200 is provided with a control terminal. In an embodiment, in order to regulate and control the air supply amount in real time according to the temperature change of the kiln body 300, temperature detection devices are respectively arranged at the corresponding positions of the first corner brick 311, the second corner brick 312 and the pool wall brick joint 320. The temperature detection device is connected with the control terminal. The temperature detecting device sends the detected temperature data to the control terminal, and the control terminal analyzes and processes the detected temperature data according to the received data and generates a control instruction to control the air volume adjusting device 230 to act.
In this embodiment, a plurality of temperature detecting devices for detecting temperatures at different positions of the wall brick slit 320 are provided at a set interval along the slit length direction of the wall brick slit 320. The temperature detection devices at different positions send the detected plurality of temperature data to the control terminal. The processor in the control terminal processes and analyzes the plurality of temperature data to obtain a temperature average value, compares the temperature average value with a set reference value, and then sends out a corresponding regulation and control instruction to control the air quantity regulating device 230 to act. The plurality of temperature detection devices are arranged on the pool wall brick joints 320, and the control terminal compares the average temperature value with the set temperature reference value, so that the air quantity regulation and control can be more accurate. Similarly, a plurality of temperature detection devices at different positions are arranged in the cooled area of the first corner brick 311, and a plurality of temperature detection devices at different positions are arranged in the cooled area of the second corner brick 312, so that real-time temperature average values of the first corner brick 311 and the second corner brick 312 are respectively obtained, and accurate regulation and control of cooling air quantity are realized.
The data transmission mode of the temperature detection device and the control terminal can be a signal transmission device based on wireless transmission technologies such as Bluetooth, infrared, WIFI and the like, can also be a wireless communication network based on GPRS and the like, and can also be a wired transmission mode.
When the angle between the adjacent first corner bricks 311 and second corner bricks 312 changes, or the center line of the first air outlet 221 is not perpendicular to the pool wall brick seam 320, and/or the center line of the second air outlet 222 is not perpendicular to the first corner bricks 311, and/or the center line of the third air outlet 223 is not perpendicular to the second corner bricks 312, in order to ensure that the maximum effective utilization rate of the blown cooling air is obtained, an angle adjusting device is provided in this embodiment, so that the air outlet 220 can rotate relative to the main air duct 210, so as to correct the angle between the center line of the first air outlet 221 and the pool wall brick seam 320, the angle between the center line of the second air outlet 222 and the first corner bricks 311, and the angle between the center line of the third air outlet 223 and the second corner bricks 312 to be in a perpendicular state.
It should be noted that, the adjacent first corner brick 311 and second corner brick 312 are perpendicular to the horizontal plane, and the tank wall brick slit 320 is also perpendicular to the horizontal plane. If the central lines of the first air outlet 221, the second air outlet 222 and the third air outlet 223 are adjusted to be parallel to the horizontal plane before the cooling system 200 works, when the cooling system 200 is suitable for corner areas with different included angles, the angle adjusting device only needs to adjust the rotation angle of the air outlet 220 in the horizontal direction, so that the central line of the air outlet 220 is perpendicular to the corner brick 310, and the angle of the air outlet 220 in the vertical direction is not required to be adjusted. In addition, under the condition that the central lines of the first air outlet nozzle 221, the second air outlet nozzle 222 and the third air outlet nozzle 223 are all adjusted to be parallel to the horizontal plane, no matter how the included angle between the adjacent corner bricks 310 changes, the first air outlet nozzle 221 is always vertically opposite to the pool wall brick joints 320 between the adjacent corner bricks 310, therefore, the angle of the first air outlet nozzle 221 does not need to be adjusted, and the material cost and time can be saved. Of course, the actual working condition is not limited to the situations, and the angle adjusting device and the corresponding angle adjusting measures can be flexibly arranged according to the actual conditions, so that the aim of optimizing the cooling effect is fulfilled.
The angle regulating device comprises an adjustable component and a connecting pipe, one end of the connecting pipe is connected with the main air pipe 210, and the other end of the connecting pipe is connected with an air inlet of the air outlet nozzle 220; the adjustable assembly is mounted on the main air duct 210 and can be repositioned relative to the main air duct 210. The air outlet 220 is disposed on the adjustable assembly and is movable synchronously with the adjustable assembly. The adjustable component can be a sizing hose which can be manually adjusted by a person. The adjustable assembly may also be an automatically commutating mechanism driven by an electric device. The connecting pipe is a deformable connecting pipe, such as a high-temperature resistant stainless steel corrugated pipe and the like.
In this embodiment, the angle adjusting device further includes a driving assembly and a position detecting device, and the adjustable assembly includes a supporting member and a rotating member. Taking the positional relationship between the center line of the second air outlet nozzle 222 and the first corner brick 311 as an example, a supporting member is mounted on the main air duct 210, a rotating member is mounted on the supporting member and can move relative to the supporting member, and the second air outlet nozzle 222 is mounted on the rotating member and moves synchronously with the rotating member. The driving assembly is connected with the rotating member to provide power for the movement of the rotating member. The driving assembly and the position detection device are connected with the control terminal. When the center line of the second air outlet nozzle 222 is not perpendicular to the first corner brick 311, the position detection device sends a signal to the control terminal; the control terminal processes and analyzes the received signals and then sends corresponding control instructions, and controls the driving assembly to operate so as to drive the rotating piece to rotate and further drive the second air outlet nozzle 222 to rotate until the center line of the second air outlet nozzle 222 is perpendicular to the first corner brick 311. At this time, the position detection device transmits another signal to the control terminal, and the control terminal processes the received signal and transmits a control command to stop the driving assembly. The principle of angle regulation between the center line of the third air outlet 223 and the second corner brick 312 is as described above.
The angle adjusting and controlling device is arranged in the cooling system 200, so that the air outlet is opposite to the area to be cooled in real time and is not inclined. Whether the position of the second air outlet nozzle 222 is deviated to cause that the central line of the second air outlet nozzle 222 is not perpendicular to the first corner brick 311 or the main air pipe 210 is moved to other positions needing cooling to change the vertical relationship, the vertical relationship can be timely adjusted to the mutually perpendicular position relationship so as to maintain the most effective cooling effect. In addition, the angle adjusting device is disposed in the cooling system 200, so that a hardware structure can be manufactured in batches, and the air outlet nozzle 220 with a corresponding deflection angle is not required to be disposed on the main air pipe 210 because the included angle of each corner position is different.
The drive assembly may be a motor or other powered device. The position detection device may be a position sensor, an alignment sensor, or the like. It should be noted that, under the condition that the position detecting device is not provided, the driving component is controlled to drive the rotating member to rotate, whether the center line of the air outlet 220 is adjusted to be perpendicular to the corner brick 310 can be observed manually, and then the driving component is controlled to be closed.
Above-mentioned cooling system 200 can cool off the pool wall brick joint 320 between the adjacent corner brick 310 of various contained angles and the adjacent corner brick 310, compares in single-point or local cooling, not only can cool off whole pool wall brick joint 320, also can cool off the regional that is corroded more serious that is close to pool wall brick joint 320 of corner brick 310 simultaneously, and the compromises strongly, simple structure, and the cooling effect is good, has avoided the infiltration problem of glass liquid.
