Description

Technical Field

[0002] During the production process of lubricating oil, the lubricating oil needs to be fully reacted in the reactor before being transferred to the storage tank for storage. During the operation of the reactor, the staff needs to observe the temperature of the lubricating oil in the reactor and the pressure of the reactor to ensure the quality of the finished lubricating oil.

[0003] However, in actual production, in order to improve production efficiency, multiple reactors are usually set up to participate in the reaction at the same time, which requires staff to inspect the reactors one by one.

Due to manual inspection, it is easy for the reactor to continue working when the parameters are unqualified. After the reaction time is over, the lubricating oil in the reactor enters the storage tank, causing the lubricating oil in the entire storage tank to be unqualified, affecting the quality of the lubricating oil.

[0018] A lubricating oil production line monitoring system, combined with Figure 1 to Figure 2 As shown, it includes a reactor 1, a storage tank 2 and a control box 8. The reactor 1 is provided in multiple pieces for reacting the lubricating oil material, the storage tank 2 is used to store the finished lubricating oil, the control box 8 is used to monitor the reactor state, and a PLC controller is provided in the control box 8. The discharge end of the reactor 1 is connected to the storage tank 2 through a feed pipe 5.

[0019] A stirring blade is arranged in the reactor 1, and a stirring motor is arranged above the reactor 1. The stirring shaft of the stirring motor passes through the reactor and is connected to the stirring blade, which is used to drive the stirring blade to rotate to stir the lubricating oil material in the reactor. The input end of the stirring motor is connected to the output end of the PLC controller.

[0020] A pressure gauge 4 and an alarm 3 are provided above the reactor 1. The pressure gauge 4 is used to detect the pressure information in the reactor, and the alarm 3 is used to sound an alarm when an abnormality occurs in the reactor to remind the staff to handle it in time. The output end of the pressure gauge is connected to the input end of the PLC controller, and the output end of the PLC controller is connected to the input end of the alarm.

[0021] The alarm 3 is an audible and visual alarm. When an abnormality occurs, it reminds the staff through sound and light, so that the staff can find the abnormal reactor in time and deal with the abnormal state in time.

[0022] A sensor group is arranged inside the reactor 1 for collecting information inside the reactor. The sensor group includes a temperature sensor and a liquid level sensor. The temperature sensor is used to collect temperature information inside the reactor. The liquid level sensor is used to collect liquid level information inside the reactor. The output ends of the temperature sensor and the liquid level sensor are respectively connected to the input ends of the PLC controller.

[0023] The discharge end of the reactor 1 is provided with a discharge solenoid valve 6 for controlling the discharge of the reactor. The feed pipe 5 at the feed end of the storage tank 2 is provided with a feed solenoid valve 7 for controlling whether to feed into the storage tank. The input end of the feed solenoid valve is connected to the output end of the PLC controller.

[0024] A liquid level sensor is provided in the storage tank 2 to detect the liquid level information in the storage tank. A high-level indicator light 13 is provided above the storage tank 2 to indicate that the storage tank is full. The output end of the liquid level sensor is connected to the input end of the PLC controller, and the output end of the PLC controller is connected to the input end of the high-level indicator light. When the liquid level in the storage tank reaches the high level, the discharge solenoid valve of the reactor and the feed solenoid valve of the storage tank are closed, and the high-level indicator light is on, reminding the staff to discharge the lubricating oil in the storage tank in time.

[0025] The control box 8 is provided with an indicator light 9, a display screen 10, a setting button 11 and a control button 12. The number of the indicator lights 9 is the same as the number of the reactors 1, and is used to indicate the working status of the corresponding reactors. The indicator light 9 is a two-color indicator light. Green represents that the reactor is working normally, and red represents that the reactor is working abnormally.

The output ends of the setting button and the control button are respectively connected to the input ends of the PLC controller, and the output ends of the PLC controller are respectively connected to the input ends of the indicator light and the display screen.

[0026] When the utility model monitors the reactor, the pressure and temperature in the reactor are detected by the temperature sensor and pressure gauge of each reactor. When the temperature and pressure exceed the set value, it indicates that the reactor is working abnormally, and the indicator light of the control box corresponding to the reactor lights up. At the same time, the alarm above the reactor sounds an alarm, which can help the staff to quickly locate the reactor with abnormal operation, solve the abnormal information as soon as possible, ensure the normal operation of production, and thus ensure the qualified rate of the product. At the same time, in the process of feeding and discharging the reactor, the liquid level is detected by the liquid level sensor in the reactor and the storage tank. When the liquid level in the reactor reaches a high level, the feeding is stopped and the reaction is started. When discharging, when the finished lubricating oil in the storage tank reaches a high level, the feeding solenoid valve of the storage tank and the discharging solenoid valve of the reactor are closed at the same time to prevent the lubricating oil from overflowing.
