Description

Technical Field

[0001] The utility model relates to a detection system, in particular to a jacket water detection system for a copper rod rolling vertical furnace. Background Art

[0002] In the modern metallurgical industry, the copper rod continuous casting and rolling (SCR) production line is an important equipment for manufacturing high-quality copper rod. The vertical furnace in the SCR production line undertakes the key tasks of melting and heat preservation, namely melting the electrolytic copper or copper alloy raw materials to a suitable temperature by heating and ensuring continuous supply to the casting machine for the subsequent casting process. To ensure that the molten copper liquid is maintained at a constant temperature range suitable for casting, the outer wall of the vertical furnace is usually equipped with a jacket, and the temperature is controlled by a circulating water cooling system.

[0003] However, during actual operation, due to long-term operation, the water pipes in the jacket may rust or rupture, causing cooling water to leak into the high-temperature vertical furnace. Considering that the temperature of the molten copper is as high as 1100°C to 1200°C, any water entering will quickly evaporate into steam, causing a rapid expansion in volume. This may not only trigger an explosive reaction, but may also cause the molten copper to splash, posing a serious safety hazard. In addition, this situation will also destroy the environment inside the furnace, affect the stability of the molten copper temperature and the quality of continuous casting, and even cause damage to the furnace structure, forcing the production line to stop for necessary repairs.

The Advantech digital module 7 is used to receive the signal transmitted by the KingView system PC6 and control the alarm mechanism to alarm.

[0022] See Figure 2 As shown, the alarm mechanism includes an alarm light 801 and an alarm 802; the alarm light 801 and the alarm 802 are connected to the Advantech digital quantity module 7 through a transmission line. The alarm light 801 is used to emit light to alarm, and the alarm 802 is used to emit sound to alarm.

[0023] See Figure 1 、 Figure 3 、 Figure 4 and Figure 5As shown, a calibration mechanism is also included, which includes a water tank 9, a connecting plate 10, a circulation pipe 11, a water pump 12 and a support; the water tank 9 is used to store clean water; a connecting plate 10 is installed on the top of the water tank 9; a circulation pipe 11 is provided on the upper side of the connecting plate 10; a water pump 12 is installed on the lower right side of the water tank 9, and the left end of the circulation pipe 11 is connected to the upper left side of the water tank 9, and the other end of the circulation pipe 11 passes through the top of the water tank 9 and is connected to the water outlet of the water pump 12, so that the water pump 12 can draw the clean water in the water tank 9 into the circulation pipe 11 for water circulation; the support includes a connecting frame 1301 and a movable frame 1302, the connecting frame 1301 is connected to the left side of the circulation pipe 11, and the movable frame 1302 is slidably installed on the right side of the connecting frame 1301, and the two ultrasonic flow detection probes 3 are both connected to the front side of the movable frame 1302.

[0024] See Figure 3 and Figure 4 As shown, an electromagnetic flowmeter 14 is also included; an electromagnetic flowmeter 14 is installed on the upper right side of the circulation pipe 11, and the electromagnetic flowmeter 14 is used to detect the flow rate of clean water in the circulation pipe 11.

In this way, the clean water can be circulated in the water tank 9 and the circulation pipe 11, and then the electromagnetic flow meter 14 is used. The water flow in the circulation pipe 11 is detected, and then the water flow in the circulation pipe 11 is detected by the ultrasonic flow detection probe 3, and then the data detected by the electromagnetic flowmeter 14 is compared with the data detected by the ultrasonic flow detection probe 3, so as to calibrate the data detected by the ultrasonic flow detection probe 3. After the data detected by the ultrasonic flow detection probe 3 is calibrated, the water pump 12 is controlled to be closed, and then the movable frame 1302 and the ultrasonic flow detection probe 3 are driven forward and reset by the electric push rod 15 until the ultrasonic flow detection probe 3 is flush with the water pipe 1, and then the ultrasonic flow detection probe 3 is used to calibrate the water flow in the water pipe 1. The water flow is continuously detected, and the ultrasonic flow detection probe 3 sends the detected water flow data intermittently to the ultrasonic flow controller 2. At the same time, the water pressure in the water pipe 1 is detected by the pressure sensor 5, and the pressure sensor 5 sends the detected water pressure data intermittently to the Advantech analog module 4. When the ultrasonic flow controller 2 receives the water flow data, the ultrasonic flow controller 2 sends the water flow data to the Advantech analog module 4. After receiving the water pressure data and water flow data, the Advantech analog module 4 transmits the water pressure data and water flow data to the KingView system PC6. The KingView system PC6 then receives the received data. The data is compared with the preset data to determine whether there is an abnormality: if there is no abnormality, no additional operation is required; if there is an abnormality, the KingView system PC6 will send the abnormal signal to Advantech digital module 7, and then Advantech digital module 7 will control the alarm light 801 and the alarm 802 to turn on together, so that the alarm light 801 lights up and the alarm 802 sounds an alarm, thereby reminding the workers that there is an abnormality, thereby facilitating the workers to carry out maintenance in time. After the maintenance is completed, the Advantech digital module 7 will control the alarm light 801 and the alarm 802 to turn off together, so that the alarm light 801 goes out and the alarm 802 stops sounding.
