Description

Technical Field

[0001] The utility model relates to the technical field of glass manufacturing, in particular to a backwashing device for high-aluminum ultra-thin glass water cooling equipment. Background Art

[0002] In float glass production, the molten glass is laid flat in a tin bath and formed, so the tin bath section is also called the forming section. High-aluminum ultra-thin glass is very thin, with a minimum thickness of 0.25mm. Therefore, glass forming has very high requirements for the environment in the tin bath. Once the environment in the tin bath fluctuates, it is very easy to cause unstable production quality. In order to maintain a stable ambient temperature in the bath, the tin bath section is equipped with many water-cooling devices. However, after long-term use, water-cooling devices may accumulate dirt, resulting in poor water cooling effect and even clogged water pipes, affecting the normal use of the water-cooling equipment. In order to ensure the normal operation of the water-cooling equipment, it is necessary to clean the water-cooling equipment with poor water cooling effect to remove dirt and restore the water cooling effect. Existing water-cooling equipment does not have an online cleaning function and can only be cleaned after the water-cooling equipment is removed from the tin bath. The process of removing the water-cooling equipment from the tin bath will cause environmental fluctuations in the tin bath, affecting production quality. Utility Model Content

The water-cooling device 3 maintains the ambient temperature and pressure in the tin bath where the glass liquid is located stable; the cooling water circulation pipeline is connected to one end of the water-cooling device 3. During cooling, the cooling water enters the water-cooling device 3 through the cooling water circulation pipeline and returns from the backwashing circulation pipeline; the backwashing circulation pipeline is connected to the other end of the water-cooling device 3. During backwashing, the cleaning liquid enters the water-cooling device 3 through the backwashing circulation pipeline and returns from the cooling water circulation pipeline, thereby cleaning the water-cooling device 3. As a result, the utility model solves the problem that the current water-cooling device needs to be withdrawn from the tin bath before it can be cleaned, and the process of withdrawing the water-cooling device from the tin bath will cause environmental fluctuations in the tin bath, affecting production quality.

[0026] In some embodiments, a return water tee 10 is provided on the backwash circulation pipeline, which is connected to the return water valve 4, the return water main valve 11 and the backwash water supply valve 12 respectively to realize the passage of the backwash circulation pipeline;

[0027] The return valve 4 is connected to the water cooling device 3 through a pipeline, the return main valve 11 is located at the other end, and the backwash water supply valve 12 is connected to the booster pump 15 through the backwash water supply pipe 13.

[0028] In a further embodiment, a return water temperature and pressure integrated sensor 9 is also provided on the return water tee 10 to monitor the outlet water temperature and pressure of the water cooling equipment 3 in real time. Once the temperature difference or water pressure difference exceeds the standard, an online backwash operation can be performed to clean the water cooling equipment.

[0029] In some embodiments, the cooling water circulation pipeline is provided with a cold water tee 7, a cold water main valve 6 and a backwash return valve 5, wherein the cold water valve 1 is connected to the water cooling equipment 3 through a pipeline, and the backwash return valve 5 is connected to the backwash trolley 18 storing the cleaning liquid 16 through the backwash return pipe 14, and a cold water main valve 6 is provided at the other end.

[0030] In a further embodiment, a cold water temperature and pressure integrated sensor 8 is provided on the cold water tee 7 to monitor the inlet water temperature and pressure of the water cooling device 3 in real time.

[0031] In a further embodiment, the booster pump 15 is connected to a backwashing trolley 18 storing the cleaning fluid 16 via a high-pressure pump water inlet pipe 17 .

[0032] In actual production, once the temperature difference or water pressure difference is found to be excessive, online backwashing can be performed to clean the water cooling equipment.

[0033] During backwashing: With the backwash water supply valve 12 closed, first start the booster pump 15 to pump cleaning fluid 16 into the high-pressure pump inlet pipe 17. Then, close the cold water main valve 6 and the return water main valve 11 to close the cold water pipeline. Simultaneously, open the backwash return valve 5 and the backwash water supply valve 12, open the backwash pipeline, and use the cleaning fluid 16 to circulate and clean the water-cooled equipment 3. Stop the backwashing operation until the temperature and pressure differentials indicated by the cold water temperature and pressure integrated sensor 8 and the return water temperature and pressure integrated sensor 9 return to normal. Close the backwash return valve 5 and the backwash water supply valve 12 to close the backwash pipeline. Simultaneously, open the cold water main valve 6 and the return water main valve 11 to open the cold water pipeline and resume normal use. Then, turn off the booster pump 15.

[0034] The invention aims to achieve the following objectives: real-time monitoring of the inlet and outlet water temperature and pressure of the water cooling equipment: by configuring a temperature and pressure integrated sensor at the inlet and outlet water pipes of the water cooling equipment 3, the inlet and outlet water temperature and pressure of the water cooling equipment 3 are monitored in real time, and by comparing the temperature difference and water pressure difference, the water cooling effect of the equipment is understood;

[0035] The water-cooling device 3 can be cleaned online without exiting the tin bath, without affecting normal production. A backwash cart 18 equipped with a high-pressure pump 15 is installed. Four ball valves are added to the inlet and outlet pipes of the water-cooling device 3. These valves are used to close the cooling water circulation line during production and open the backwash circulation line. The high-pressure pump 15 then delivers cleaning fluid 16 from the backwash cart 18 to the water-cooling device 3 for circulation and cleaning. For optimal cleaning results, the water flow is reversed from the original flow. After cleaning, the backwash line is closed, and the cooling water circulation line is restored for normal use.
