[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1, refer to Figs. 1-3 A protective barrel conveying device includes a nitrogen pipeline 1, a control valve 2 installed on the outer wall of the nitrogen pipeline 1, a water seal insertion pipe 5 fixedly connected to the nitrogen pipeline 1 through a tee pipe, and a protective water seal 4 inserted into the outer wall of the water seal insertion pipe 5, a nitrogen branch pipe 3 fixedly connected to one end of the outer wall of the nitrogen pipeline 1, and a nitrogen hose 7 fixedly connected to one end of the outer wall of the nitrogen branch pipe 3.

[0024] In this embodiment, nitrogen is used as the driving gas. By controlling the nitrogen pressure, the nitrogen is depressurized in one step using control valve 2, and the nitrogen pressure is controlled by a water seal to ensure that it does not exceed the maximum pressure. This allows the organic liquid to be transported in an oxygen-free atmosphere. The device is simple, safe and reliable.

[0025] Example 2, refer to Fig. 3 A protective barrel conveying device is provided, wherein a quick connector 8 is fixedly connected to the outer wall of one end of a nitrogen hose 7, and an oil barrel 10 is provided at one end of the quick connector 8. An oil pouring hose 15 is provided inside the oil barrel 10, and an oil outlet flexible connection 11 is provided on the outer wall of one end of the oil pouring hose 15. An oil outlet quick connector 12 is installed between the oil outlet flexible connection 11 and the oil outlet flexible connection 12. An oil outlet pipe 16 is provided at one end of the oil outlet flexible connection 11, and a receiving container 18 is inserted into the bottom of the outer wall of the oil outlet pipe 16.

[0026] In this embodiment, the device is simple and easy to manufacture without complicated processes. Nitrogen is used as the driving gas to avoid contact between organic liquid and air, which makes it safer. The overpressure protection water seal 4 ensures that the oil drum 10 does not bulge during the oil transportation process. The oil drum 10 can hold the minimum amount of oil, and it is very convenient and quick to change drums without the occurrence of siphoning oil spillage.

[0027] Reference Fig. 2 An oil outlet quick connector 12 is installed between the oil outlet flexible connector 11 and the oil outlet flexible connector 11.

[0028] Reference Fig. 2 The top outer wall of the protective water seal 4 is equipped with a water seal vent pipe 6.

[0029] Reference Fig. 3 An oil drum balance hole 9 is provided on one side of the top outer wall of the oil drum 10, and the quick connector 8 is located inside the oil drum balance hole 9.

[0030] Reference Fig. 3An oil pouring port 13 is provided on the other side of the top outer wall of the oil drum 10, and an oil pouring hose 15 is installed inside the oil pouring port 13. An anti-static oil inlet 14 is installed on the outer wall of the other end of the oil pouring hose 15.

[0031] Reference Fig. 3 An electrostatic grounding wire 17 is fixedly connected to the bottom of the outer wall of the oil outlet pipe 16.

[0032] Reference Fig. 3 A one-way valve 19 is installed on the outer wall of the oil outlet pipe 16.

[0033] Working principle: Step 1: First disconnect the flexible connection of the pipeline from nitrogen to oil tank 10, and reduce the pressure of nitrogen by controlling the size of valve 2 to prevent nitrogen from escaping from water seal vent pipe 6;

[0034] Step 2: Connect the flexible pipe for nitrogen to enter the oil drum 10. The nitrogen will put pressure on the liquid inside the oil drum 10, and the organic liquid will be forced into the receiving container 18 through the anti-static oil inlet 14 and the one-way valve 19.

[0035] Step 3: If no nitrogen gas comes out of the water seal vent pipe 6, it means that the maximum pressure has not been exceeded. If nitrogen gas comes out of the water seal vent pipe 6, the control valve 2 needs to be closed further until no nitrogen gas comes out.

[0036] Step 4: When the liquid in the barrel is nearly empty, by changing the angle of the oil barrel 10, the anti-static oil inlet 14 inside the oil barrel 10 moves to the bottom by gravity through the flexible connection, which can maximize the compression of air and storage of oil.
