[0002] In the process of preparing or using organic solvents, it is necessary to store the organic solvents in a container, and then use a pump and a pipeline to pump the organic solvents into the corresponding processing equipment. The existing device connection method is that the liquid inlet end of the pump is connected to the storage device through a connecting pipe, and the liquid outlet end of the pump is connected to the corresponding processing equipment through a connecting pipe. When the processing equipment is stopped, the organic solvent is not used at this time. The organic solvent in the storage device has pressure, and it is easy for the organic solvent to flow into the pipeline or the pump body, causing leakage of the organic solvent, which has caused great inconvenience to production and processing. Therefore, a valve is equipped on the pipeline to control the opening and closing of the pipeline to prevent leakage when the organic solvent is not used. However, in the busy processing process, the staff often forgets to close the valve or the valve is not completely closed, resulting in the pipeline The effect of preventing leakage is not ideal, and the organic solvent will still leak during the shutdown stage, wasting raw materials and affecting the processing environment.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0024] See also Figure 1-4 As shown, it is an embodiment of the utility model: an anti-leakage system for organic solvents, comprising a shell 10, the shell 10 has a channel 16 inside, the shell 10 has a liquid inlet end 14 and a liquid outlet end 15, the liquid inlet end 14 is provided with a first connecting pipe 11, the liquid outlet end 15 is provided with a second connecting pipe 12, the first connecting pipe 11 and the second connecting pipe 12 are both connected to the channel 16, and a baffle 20 is provided inside the shell 10. When the organic solvent is not used, the baffle 20 is inclined downward under the action of gravity, and the peripheral side of the baffle 20 is in conflict with the side wall of the channel 16, thereby forming a seal for the channel 16 to prevent the leakage of the organic solvent; when the organic solvent is used, the organic solvent with a large flow rate has an impact force on the baffle 20, so that the baffle 20 is in a nearly horizontal state, and the organic solvent can flow out through the channel 16.

[0025] The baffle 20 includes a shielding portion 21 and a sealing portion 23. There are two sealing portions 23. The shielding portion 21 has a first end 24 and a second end 25. One of the sealing portions 23 is located at the first end 24 of the shielding portion 21, and the other sealing portion 23 is located at the second end 25 of the shielding portion 21. The sealing portion 23 is made of elastic material. The end of the sealing portion 23 away from the shielding portion 21 has an inclined surface, so that the sealing portion 23 can fully contact the inner wall of the channel 16 and form a good seal for the channel 16. The front and rear sides of the baffle 20 are both provided with sealing gaskets, so that the front and rear sides of the baffle and the channel 16 can be in a sealed state. The front and rear sides of the baffle 20 are both fixedly provided with support columns 22. The support columns 22 are located at the center of the side of the baffle 20. The support columns 22 are rotatably connected to the support seats 13 on both sides of the housing 10. The support columns 22 are used to support the baffle 20 and enable the baffle 20 to rotate around the axis of the support columns 22 inside the channel 16.

[0026] A cavity 40 is provided inside the support column 22 along the length direction. In the present embodiment, the number of the cavities 40 is three to ensure the stability of the baffle 20 during rotation. In other embodiments, the number of the cavities 40 is one, two, four or more. The specific number of the cavities 40 is not limited here. The center of the cavity 40 is located near the second end 25. A flowable object is placed inside the cavity 40 so that the center of gravity of the baffle 20 and the flowable object as a whole is located near the second end 25. The flowable object is a granular object, such as sand and gravel particles, or a liquid substance.

[0027] When the processing device is in a shutdown state and there is no flowing organic solvent in the channel 16, the second end 25 can be located at the bottom and close to the liquid inlet end 14, and the first end 24 is located at the top and close to the liquid outlet end 15, forming a seal for the channel 16, and blocking the organic solvent with a lower flow rate leaking in the pipeline, thereby preventing the leakage of the organic solvent; when the processing device is in a startup state, a high-speed flowing organic solvent flows in the channel 16 under the action of the pump, and the high-speed flowing organic solvent acts on the first end 24, the baffle 20 is deflected, the channel 16 is in an open state, and the flowable object flows in the cavity 40 toward the first end 24, so that the center of gravity of the baffle 20 and the flowable object as a whole is close to the center position, so that the baffle 20 is kept in a horizontal state as much as possible to reduce the resistance of the baffle 20 to the fluid and reduce the pressure loss of the fluid.

[0028] It should be noted that even if the center of gravity of the baffle 20 and the flowable object as a whole approaches the central position, the center of gravity of the baffle 20 and the flowable object as a whole is still located at an end close to the second end 25, so that when the liquid stops flowing in the channel 16, the baffle 20 can be reset.

[0029] The liquid inlet end 14 is threadedly connected to a liquid inlet pipe 11, and the liquid outlet end 15 is threadedly connected to a liquid outlet pipe 12, wherein the end of the liquid inlet pipe 11 away from the liquid inlet end 14 is connected to a container for containing an organic solvent through a valve, and the liquid outlet pipe 12 is connected to the liquid inlet end of the pump, and the liquid inlet pipe 11 and the liquid outlet pipe 12 are coaxially arranged, so that the shell 10 can rotate around the axis of the liquid inlet pipe 11 to adjust the overall horizontality of the shell 10 and increase the stability of the device when in use.

[0030] When an organic solvent liquid is introduced into the channel 16 , a guide plate 30 is installed at the liquid inlet end 14 in order to make the liquid impact the baffle 20 and rotate the baffle 20 . The guide plate 30 is tilted so that the flow direction of the organic solvent can be toward the first end 24 , so that the baffle 20 rotates to open the channel 16 .

[0031] In this specific embodiment, when the processing device is in a shutdown state and there is no flowing organic solvent in the channel 16, the baffle 20 forms a seal on the channel 16, thereby blocking the organic solvent with a lower flow rate leaking in the pipeline and preventing the leakage of the organic solvent; when the processing device is in a startup state, a high-speed flowing organic solvent flows in the channel 16 under the action of the pump, and the high-speed flowing organic solvent acts on the first end 24, the baffle 20 is deflected, the channel 16 is in an open state, and the flowable object flows in the cavity 40 toward the first end 24, so that the center of gravity of the baffle 20 and the flowable object as a whole approaches the center position, so that the baffle 20 is kept as horizontal as possible.
