[0025] like Figure 1As shown, the embodiment relates to a glass kiln neck water bag device, the glass kiln neck water bag device part of the structure is arranged in the kiln, and is characterized in that it includes: a support assembly 10, a water bag assembly 20 and an adjustment assembly 30. The water bag assembly 20 is connected to the support assembly 10, and the water bag assembly 20 includes a cooling pipe 21, and the cooling pipe 21 is at least provided in one group, and each group of cooling pipes 21 includes an inlet pipe 211 and an outlet pipe 212, and the inlet pipe 211 and the outlet pipe 212 are connected, and the height of the inlet pipe 211 is lower than the height of the glass liquid. The adjustment assembly 30 includes a first solenoid valve 31, a second solenoid valve 32, a thermocouple 33 and a control module 34, the first solenoid valve 31 is arranged on the inlet pipe 211, the second solenoid valve 32 is arranged on the outlet pipe 212, the thermocouple 33 is at least provided in one group, and at least one group of thermocouples 33 is arranged on the outlet pipe 212, and the first solenoid valve 31, the second solenoid valve 32 and the thermocouple 33 are all electrically connected to the control module 34.

[0026] The technical solution of this embodiment is applied to the glass furnace neck water bag device, including: a support assembly 10, a water bag assembly 20 and an adjustment assembly 30. The water bag assembly 20 is connected to the support assembly 10 and supported by the support assembly 10 to prevent the water bag assembly 20 from deflecting and causing the glass liquid to overflow. The water bag assembly 20 includes a cooling pipe 21, and at least one group of cooling pipes 21 is provided. Each group of cooling pipes 21 includes an inlet pipe 211 and an outlet pipe 212. The inlet pipe 211 and the outlet pipe 212 are connected. The height of the inlet pipe 211 is lower than the height of the glass liquid. The water inlet pipe 211 is immersed in the glass liquid to cool the glass liquid, and at the same time, it can block the unmelted scum or insoluble matter in the glass liquid. The regulating assembly 30 includes a first solenoid valve 31, a second solenoid valve 32, a thermocouple 33 and a control module 34. The first solenoid valve 31 is arranged on the water inlet pipe 211, the second solenoid valve 32 is arranged on the water outlet pipe 212, at least one group of thermocouples 33 is arranged, and at least one group of thermocouples 33 is arranged on the water outlet pipe 212. The first solenoid valve 31, the second solenoid valve 32 and the thermocouple 33 are all electrically connected to the control module 34. The thermocouple 33 can detect the temperature of the water in the water outlet pipe 212 and transmit the detection result to the control module 34. The control module 34 controls the first solenoid valve 31 and the second solenoid valve 32 according to the detection result, so as to achieve accurate regulation of the water temperature of the cooling pipe 21, and thus control the cooling effect of the glass liquid within the required range. The technical solution of this embodiment effectively solves the problem of low accuracy of water temperature regulation of the neck water bag in the prior art.

[0027] It should be noted that, since the cooling water flows out through the outlet pipe 212 after sufficient heat exchange with the glass liquid, the thermocouple 33 is set on the outlet pipe 212 for detection, which can explain the heat exchange situation. Where the thermocouple 33 is specifically located in the outlet pipe 212 has little effect on the detection result. Multiple groups of thermocouples can also be set, both in the water inlet pipe 211 and the outlet pipe 212, so that the cooling water temperature change in the cooling pipe 21 can be more sensitive, which is convenient for the control module 34 to adjust the cooling water temperature in time to make it within the required range. The control module 34 can use a PLC control system. The PLC control system controls the opening of the first solenoid valve 31 and the second solenoid valve 32 according to the comparison of the detection temperature and the set temperature, and then adjusts the cooling water volume to achieve the purpose of adjusting the temperature. The thermocouple 33 and the cooling pipe 21 can be welded, or they can be connected by flanges, threads, etc. The welding connection method is not only firm and has good sealing performance, but also can avoid leakage at the connection between the thermocouple 33 and the cooling pipe 21. The thermocouple directly contacts the cooling water for temperature measurement.

[0028] It should also be noted that a mounting hole is provided on the side wall of the kiln, and the glass kiln neck water bag device is inserted into the mounting hole, and at least part of the structure extends deep into the kiln.

The cooling section is connected to the first end of the connecting section, and the second end of the connecting section is connected to the supporting section. The cooling section is located in the kiln, flush with the glass liquid surface, and penetrates into the glass liquid for heat exchange and blocking scum. The connecting section is used to connect the cooling section and the supporting section. The supporting section passes through the mounting hole on the side wall of the kiln and extends to the outside of the kiln. It is supported by the support assembly 10 to prevent deflection.

[0031] like Figure 1As shown, in some embodiments, the lifting structure 12 further includes a bracket, and the drive motor 121 is arranged on the bracket and fixed by bolts. There are multiple drive motors 121 and lifting screws 122, and the drive motors 121 and the lifting screws 122 correspond to each other one by one. The drive motor 121 is electrically connected to the control module 34. The control module 34 controls the drive motor 121 to adjust the position of the nut seat 123 on the lifting screw 122. The support structure 11 includes a support seat 111 and a support frame 112, the support seat 111 and the nut seat 123 are connected, the support seat 111 can move synchronously with the movement of the nut seat 123, the support frame 112 is arranged on the support seat 111, and can move with the movement of the support seat 111, the support frame 112 faces the direction of the cooling pipe 21, and the support frame 112 is provided with a matching hole, and the support section of the cooling pipe 21 passes through the matching hole, so as to adjust the height of the cooling pipe 21 (limited by the size of the mounting hole on the side wall of the kiln) with the movement of the support frame 112.

[0032] It should be noted that the water inlet pipe 211 and the water outlet pipe 212 are high temperature resistant stainless steel pipes that are not easily deformed. The right sides of the water inlet pipe 211 and the water outlet pipe 212 are connected to the water tank through a hose, so when the height is adjusted, the water inlet and return water are not affected.

The scraper structure 22 is arranged on one side of the cooling pipe 21 (where scum can accumulate), a chute is arranged on the outer side of the cooling section pipe wall, and the slider 221 is movably arranged in the chute. The side wall of the kiln is provided with a first opening, through which a scraper rod 223 passes. When too much scum accumulates, the operator holds the hand-held section of the scraper rod 223 to drive the first connecting section to move. The scraper rod 223 is rotatably connected to the scraper plate 222. The scraper plate 222 is connected to the slider 221 and can move along the chute to scrape the scum to one side. The side wall of the kiln has a second opening, from which the scum is removed. A material drop chute is provided below the second opening, which is connected to the outer wall of the kiln. The scum falls out of the second opening and into the material drop chute. The size of the first opening and the second opening is set to ensure that the scraping and clearing are not affected when the height of the cooling pipe 21 is adjusted.
