Referring to fig. 2, when the molten glass in the kiln body 300 flows through the corner area, the flow rate of the molten glass is abruptly changed, so that the first corner brick 311 and the second corner brick 312 at the corner and the tank wall brick joint 320 therebetween are more permeable, and corrosion of the first corner brick 311, the second corner brick 312 and the tank wall brick joint 320 is promoted. The cooling system 200 is used for simultaneously cooling the erosion-prone areas of the first corner brick 311 and the second corner brick 312 and the tank wall brick joints 320, so that the maintenance cost of the kiln body 300 is reduced, and the production reliability is improved. This embodiment refers to the vulnerable areas of first corner brick 311 and second corner brick 312 and pool wall brickwork joint 320 as corner areas.

The main duct 210 is used for conveying cooling air to the air outlet 220, and the air outlet 220 blows air to the first corner brick 311, the second corner brick 312 and the tank wall brick joint 320.

Referring to FIG. 3, in the present embodiment, the main duct 210 is a cylindrical structure, and its axial direction is parallel to the brick joints 320 of the pool wall. The direction of the primary air duct 210 parallel to the wall brickwork joints 320 is defined as the longitudinal or length direction of the primary air duct 210. At least three longitudinal rows of air outlets 220 parallel to the brick joints 320 of the pool wall are arranged on the main air duct 210 along the circumferential direction, and each longitudinal row comprises a plurality of air outlets 220.

Referring to fig. 2 and 3, a plurality of first air outlets 221 are provided at a longitudinal position of the main duct 210 opposite to the brickwork joints 320 for blowing air to cool the brickwork joints 320. A plurality of second air outlets 222 and a plurality of third air outlets 223 are respectively disposed on both sides of the first air outlet 221 along the longitudinal direction of the main duct 210. Wherein the second air outlet nozzle 222 is used for air-cooling the area of the first corner brick 311 near the pool wall brick joint 320, and the third air outlet nozzle 223 is used for air-cooling the area of the second corner brick 312 near the pool wall brick joint 320. 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 and the third air outlet nozzle are both arranged at the position, close to the pool wall brick joint 320, of the corner brick 310, so that the areas, which are easily eroded, of the first corner brick 311 and the second corner brick 312 can be cooled in a targeted manner. The first air outlet nozzles 221, the second air outlet nozzles 222 and the third air outlet nozzles 223 are arranged on the main air pipe 210 in a matrix manner; the first air outlet nozzle 221, the second air outlet nozzle 222, and the third air outlet nozzle 223 are located at the same height in the circumferential direction of the main duct 210.

In this embodiment, the diameter of the main air duct 210 is 80mm-200mm, the longitudinal distance between the air outlets of the first air outlet 221 on the main air duct 210 is set to be 5mm-30mm, and similarly, the longitudinal distance between the air outlets of the second air outlet 222 and the longitudinal distance between the air outlets of the third air outlet 223 are also set to be 5mm-30 mm. In other embodiments, the main duct 210 with a corresponding diameter may be selected according to the size of the included angle between the first corner brick 311 and the second corner brick 312, and/or the longitudinal distance between adjacent air outlets of the first air outlets 221 may be adaptively adjusted, the longitudinal distance between adjacent air outlets of the second air outlets 222 may be adjusted, and the longitudinal distance between adjacent air outlets of the third air outlets 223 may be adjusted. Similarly, the circumferential distance between the second air outlet nozzle 222 and the first air outlet nozzle 221 and the circumferential distance between the third air outlet nozzle 223 and the first air outlet nozzle 221 may also be determined according to actual needs.

The arrangement number of the first air outlet nozzle 221, the second air outlet nozzle 222 and the third air outlet nozzle 223 in the longitudinal direction of the main air duct 210 is set reasonably according to the length of the brick joint 320 of the pool wall.

In other embodiments, a set of air outlets may be further disposed beside the second air outlet 222 of the main air duct 210 along the longitudinal direction of the main air duct 210, and a set of air outlets may be further disposed beside the third air outlet 223 of the main air duct 210 along the longitudinal direction of the main air duct 210 to enlarge the cooling area and sufficiently cool the portions of the first corner brick 311 and the second corner brick 312 near the wall brick joint 320. In other embodiments, a plurality of sets of air outlets 220 arranged in parallel in the longitudinal direction may be provided as required.

In this embodiment, the air outlet 220 is a hollow flat cone structure, that is, the sizes of the openings at the two ends of the air outlet 220 are different. One end of the air inlet of the air outlet nozzle 220 is connected with the main air duct 210, and one end of the air outlet nozzle 220 faces to the positions to be cooled of the first corner brick 311 and the second corner brick 312 and the brick joint 320 of the pool wall. The aperture of the air inlet of the first air outlet nozzle 221 facing the brick joint of the pool wall is larger than that of the air outlet of the first air outlet nozzle 221, so that a strong air flow reinforced heat dissipation effect is formed at the air outlet. The aperture of the air inlet of the second air outlet nozzle 222 facing the corner brick is not larger than the aperture of the air outlet of the second air outlet nozzle 222, so that the second air outlet nozzle 222 has a larger cooling range relative to the first corner brick 311. The aperture of the air inlet of the third air outlet nozzle 223 facing the corner brick is not larger than the aperture of the air outlet of the third air outlet nozzle 223, so that the third air outlet nozzle 223 has a larger cooling range with respect to the second corner brick 312.

Referring to fig. 2, the center line of the first air outlet 221 is perpendicular to the joint 320 of the pool wall, the center line of the second air outlet 222 is perpendicular to the first corner brick 311, and the center line of the third air outlet 223 is perpendicular to the second corner brick 312. The above-mentioned mutually perpendicular positional relationship can avoid the problem that the most effective cooling effect cannot be obtained due to the wind direction deflection caused by the angle inclination of the air outlet nozzle 220.

The height of the main duct 210 is adapted to the height of the tank wall brickwork joints 320. Referring to fig. 3, in the longitudinal direction of the main duct 210, the outlet of the uppermost one of the third air outlets 223 is inclined downward by a predetermined angle to prevent the cooling air from entering the space region containing the high-temperature molten glass in the kiln 300 from the upper edge of the corner brick 310, and affecting the melting temperature of the space region. The set angle of downward inclination is 30-60 degrees. Similarly, the air outlet of the uppermost one of the first air outlets 221 and the air outlet of the uppermost one of the second air outlets 222 are inclined downward by a predetermined angle.

The air outlet nozzle 220 may be directly connected to the main air duct 210, or may be connected through other intermediate members.

Referring to fig. 3, an air volume adjusting device 230 is disposed at an air inlet of the main air duct 210, and is used for adjusting and controlling the air volume entering the main air duct 210. It should be noted that, in other embodiments, an induced duct 240 may be further provided for conveying the cooling air into the main duct 210, at this time, the air volume adjusting device 230 may be disposed at an outlet position of the induced duct 240, and the disposition position of the air volume adjusting device 230 is not limited herein as long as the air volume of the cooling air blown out from the air outlet 220 is adjusted.

The air outlet nozzle 220 is made of heat-resistant stainless steel, and may be made of other high-temperature-resistant materials. The main air duct 210 is made of heat-resistant stainless steel, and may be made of other high-temperature-resistant materials. In other embodiments, the primary air duct 210 may have an elliptical cylindrical configuration 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 one embodiment, in order to adjust and control the air output 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 tank wall brick joint 320. The temperature detection device is connected with the control terminal. The temperature detection device sends the detected temperature data to the control terminal, and the control terminal analyzes and processes the 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 detection devices for detecting the temperatures of the various locations of the wall joints 320 are provided at predetermined intervals along the length of the wall joints 320. The temperature detection devices at different positions send a plurality of detected 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, and sends out a corresponding regulation and control instruction after comparing the temperature average value with a set reference value to control the air volume adjusting device 230 to operate. A plurality of temperature detection devices are arranged on the brick joints 320 of the pool wall, and the control terminal compares the average temperature value with a set temperature reference value, so that the air volume regulation and control are 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 as to respectively obtain the real-time temperature average values of the first corner brick 311 and the second corner brick 312, and realize accurate regulation and control of cooling air volume.

The data transmission mode between the temperature detection device and the control terminal can be a signal transmitting device based on wireless transmission technologies such as Bluetooth, infrared and WIFI, can also be a wireless communication network based on GPRS, and can also be a wired transmission mode.

When the angle between the adjacent first corner brick 311 and second corner brick 312 is changed, or the center line of the first air outlet nozzle 221 is not perpendicular to the pool wall brick seam 320, and/or the center line of the second air outlet nozzle 222 is not perpendicular to the first corner brick 311, and/or the center line of the third air outlet nozzle 223 is not perpendicular to the second corner brick 312, in order to ensure that the blown cooling air obtains the maximum effective utilization rate, an angle adjusting and controlling device is provided in this embodiment, so that the air outlet nozzle 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 nozzle 221 and the pool wall brick seam 320, the angle between the center line of the second air outlet nozzle 222 and the first corner brick 311, and the angle between the center line of the third air outlet nozzle 223 and the second corner brick 312 to be perpendicular.

It should be noted that the adjacent first corner brick 311 and second corner brick 312 are vertical to the horizontal plane, and the wall brick joint 320 is also vertical 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 all adjusted to be parallel to the horizontal plane before the cooling system 200 works, when the cooling system 200 is applied to corner regions with different included angles, the angle adjusting device only needs to adjust the rotation angle of the air outlet 220 in the horizontal direction, and the central line of the air outlet 220 can be perpendicular to the corner brick 310 without adjusting the angle of the air outlet 220 in the vertical direction. 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 always vertically faces the brick joint 320 of the pool wall 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 the time can be saved. Of course, the actual working conditions are not limited to the situations, and the angle regulating device and the corresponding angle regulating measures can be flexibly arranged according to the actual conditions, so that the purpose of optimal cooling effect is achieved.

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 primary air duct 210 and can be repositioned relative to the primary air duct 210. The air outlet nozzle 220 is disposed on the adjustable assembly and is movable in synchronization with the adjustable assembly. The adjustable component can be a sizing hose and can be manually adjusted by a person. The adjustable assembly may also be a self-reversing 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 position relationship between the center line of the second nozzle 222 and the first corner brick 311 as an example, the supporting member is installed on the main duct 210, the rotating member is installed on the supporting member and can move relative to the supporting member, and the second nozzle 222 is installed on the rotating member and can move synchronously with the rotating member. The driving assembly is connected with the rotating piece to provide power for the movement of the rotating piece. The driving assembly and the position detection device are connected with the control terminal. When the central 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 sends a corresponding control instruction after processing and analyzing the received signal, and controls the driving component to operate so as to drive the rotating member 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 the moment, the position detection device sends another signal to the control terminal, and the control terminal sends a control instruction to stop the operation of the driving assembly after processing the received signal. The principle of angle adjustment between the center line of the third air outlet 223 and the second corner brick 312 is the same as described above.

The angle regulating device is arranged in the cooling system 200, so that the air outlet can be directly opposite to the area needing cooling in real time without deflection. No matter the position of the second air outlet nozzle 222 is deviated to make the center line of the second air outlet nozzle 222 not perpendicular to the first corner brick 311, or the vertical relationship is changed by moving the main duct 210 to other positions needing cooling, the position relationship can be adjusted to be perpendicular to each other in time to maintain the most effective cooling effect. In addition, the angle adjusting device is arranged in the cooling system 200, so that a hardware structure can be manufactured in batch, and the air outlet nozzle 220 with a corresponding deflection angle is not required to be arranged on the main air pipe 210 due to different included angles of each corner position.

The drive assembly may be a motor or other device that can provide power. The position detection device may be a position sensor, an alignment sensor, or the like. It should be noted that, in the case that the position detecting device is not provided, the driving assembly is controlled to drive the rotating member to rotate, and 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 assembly is controlled to be closed.

Above-mentioned cooling system 200 can cool off the adjacent turning brick 310 of various contained angles and the pool wall brickwork joint 320 between the adjacent turning brick 310, compare in single-point or local cooling, can not only cool off whole pool wall brickwork joint 320, also can cool off the more serious region of being corroded that is close to pool wall brickwork joint 320 of turning brick 310 simultaneously, and the compromise is strong, simple structure, and the cooling effect is good, has avoided the infiltration problem of glass liquid.

Above-mentioned melting furnace through setting up cooling system 200, can cool down to self kiln body 300. Prevent the molten glass from permeating from the brick joints 320 of the tank wall, and reduce the potential safety hazard. Meanwhile, the main air duct 210 and the air outlet nozzles 220 arranged on the main air duct 210 and communicated with the main air duct 200 can be manufactured in batches, and the cooling of the adjacent corner bricks 310 and the pool wall brick joints 320 with different included angles in the kiln body 300 can be realized without designing various air outlet nozzle 220 structures, so that the operation is convenient.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
