Description

Technical Field

[0001] The utility model relates to the technical field of spinning equipment, in particular to a visual liquid level alarm system for an oil preparation room. Background Art

[0002] The oil preparation system is a system that mixes desalted water and crude oil into a finished oil. After the desalted water and crude oil are mixed in a mixing barrel, they are placed in a storage barrel for use in workshop production.

[0003] The storage barrel is equipped with a mechanical float switch, which automatically closes when the oil is full to prevent oil overflow. However, if the float switch is blocked and oil cannot flow out, it will cause oil shortage in the workshop, resulting in product degradation. During mixing, if the oil drain valve of the storage barrel is not closed, unmixed oil will flow into the storage barrel, resulting in incorrect oil concentration. Once this oil is used on site, it will also cause product degradation. The above two methods will lead to product degradation and cause huge losses. Therefore, there is an urgent need for a visual liquid level alarm system for the oil distribution room to notify personnel in time for processing. Utility Model Content

The terminal block ensures that the connection cables of the above-mentioned various components can be normally and stably connected to the programmable processing PLC master control electrical box 10 to ensure the normal operation of the entire system.

[0026] Furthermore, multiple groups of connecting wire tubes 14 are provided with wires passing through the interior thereof, and the water inlet valve monitoring switch 5, the oil inlet valve monitoring switch 7, the oil level transmitter 9, the first alarm light 11, the remote information feedback sound and light device 12 and the second alarm light 13 are all electrically connected to the master control electrical box 10 through wires. The wires are passed through the interior of the connecting wire tube 14, and the connecting wire tube 14 and the master control electrical box 10 are connected through the quick-release connector 15. The wires are then connected to the interior of the master control electrical box 10, so that the entire system can be controlled through the master control electrical box 10. When the liquid level alarm light is working, the remote information feedback sound and light device 12 also works at the same time, which can avoid the inability to discover abnormalities in the first time when no one is working in the oil distribution room, and can allow other people to Timely invention and notification of personnel to handle, the liquid level transmitter is made of stainless steel, and the power supply is 24V low voltage, which ensures that the liquid level transmitter will not be corroded by oil and malfunction, and the 24V low voltage can ensure the safety of electricity use by users. The touch screen on the programmable PLC master control box 10 controls the PLC module to process and monitor the liquid level of the storage tank 2 and the opening and closing of the valves of the mixing tank 1 and the storage tank 2. The programmable control method is used to avoid problems during use, and the program can be replaced in time to solve the problem. The oil level transmitter 9 can monitor the liquid level of the storage tank 2 in real time and feedback to the PLC module in real time. It can detect abnormalities at the first time and notify the operator through various alarm lights to handle abnormalities in time.

[0027] Then, the quick-release connector 15 includes a connector 1501 fixedly connected to the main control box 10, a movable sleeve 1502 is slidably connected to the outside of the connector 1501, a spring 1503 is provided on the outside of the connector 1501 and located inside the movable sleeve 1502, and a plurality of groups of card balls 1504 are movably installed inside the connector 1501, the card balls 1504 are carded with the connecting wire tube 14 through the card slot 1505, the connecting wire tube 14 is plugged into the connector 1501 through the slot 1506, and the connector 1501 is connected to the inside of the connecting wire tube 14.
