The bypass components can provide a bypass path in the cooling system so as to perform maintenance on the cooling system without shutting down the water supply of the cooling system.

[0027] In order to stabilize the state of the equipment during normal production, the kiln is a key equipment for normal glass production. The cooling system is a protection system for the equipment under high temperature conditions. The cooling system effectively guarantees the working performance of the glass kiln equipment. Emergency situations may occur during the cooling process, and slow recovery or failure to discover them in time will result in the equipment not being effectively cooled. This affects the use status of the equipment and product quality. The present invention provides a cooling system for a glass kiln, which can effectively and in real time monitor the data of the water supply flow in the cooling system, and provide feedback in the first time and automatically perform corresponding effective processing in the event of a water outage.

The present invention uses the auxiliary design of the cooling standby part and specifically designs the electric automatic valve 7 in the cooling water standby pipeline 2 to ensure that the standby start-stop unit will not be mistakenly started when the main cooling part is normal, thereby further improving the stability of the cooling system.

[0032] As a preferred method, the present invention also designs a bypass pipeline 8 corresponding to the flow meter 4 and the one-way switch valve 6, and each bypass pipeline 8 is equipped with a ball valve body 5, thereby providing more bypass path options when the flow meter 4 and the one-way switch valve 6 need to be maintained or replaced, without closing the pipeline, thereby improving maintenance efficiency. In addition, the present invention also provides a ball valve body 5 on the pipeline of the pressure monitoring switch 3. The function is similar to the above-mentioned ball valve body 5, making the pressure monitoring switch 3 easy to maintain.

[0033] The present invention also provides a control method for a cooling system of a glass furnace, specifically: The main cooling part is arranged in the glass furnace and connected to an external water supply pipeline for cooling; the monitoring unit is used to monitor the working status data of the main cooling part in real time; When the control part determines that the main cooling part is abnormal based on the data monitored by the monitoring unit, the following operations are performed: Control the standby start-stop unit to start, and start the cooling standby part to supply water to the equipment of the glass furnace for cooling; At the same time, the one-way control device is controlled to ensure that the water flowing out of the cooling standby part does not flow to the water inlet direction of the main cooling part; A bypass assembly is provided in the main cooling section and the cooling standby section, and the bypass assembly can provide a bypass passage without shutting down the water supply of the cooling system, so as to perform maintenance on the cooling system; Among them, the control part determines the working status of the main cooling part according to the data fed back by the monitoring unit, and controls the opening and closing of the backup start-stop unit and the one-way control device accordingly, and uses the bypass component for maintenance to ensure the continuity and safety of the cooling process of the glass kiln.
