[0002] When storing organic matter, secondary pollution should be avoided, and toxic and hazardous waste should be ensured to pose no risk to humans. Currently, waste liquids are stored in containers with vents or ventilation tubes. The liquid in the container will evaporate into the surrounding air to a certain extent, polluting the environment and affecting the health of operators. In addition, when the waste liquid is discharged from the container, volatile and harmful gases in the container are inevitably discharged into the air. Summary of the Invention

[0003] The purpose of the present invention is to overcome the defects in the prior art and provide a waste liquid storage container with a matching discharge pipe, which can effectively solve the above-mentioned problems in the prior art.

[0009] Furthermore, the switch structure includes a piston assembly and a drive assembly, the piston assembly is used to open or close the air vent, and the drive assembly is used to drive the piston assembly to open or close the air vent.

[0010] Furthermore, the piston assembly includes a piston, a connecting rod, a guide plate, a first connecting column, a second connecting column, a spring and a guide rod. The guide rod is installed in the first pipe structure. A guide hole is opened on the guide plate. The guide plate is mounted on the guide rod through the guide hole and can move freely along the guide rod. One end of the guide plate is connected to the piston through the connecting rod, and the other end of the guide plate is connected to the first connecting column. The second connecting column is installed on the inner wall of the first pipe structure. Both ends of the spring are respectively connected to the first connecting column and the second connecting column.

[0017] Furthermore, the first pipeline structure is an inverted L-shaped structure.

[0018] The advantages and beneficial effects of the present invention are:

[0020] (2) The waste liquid storage container of the present invention is equipped with a discharge pipe to achieve smooth discharge of the stored liquid during the process, ensuring that the internal pressure of the storage container is positive, while also reducing the volatilization of the liquid during the sealing process, thereby achieving the best use effect of the sealed container.

[0021] (3) The waste liquid storage container of the present invention is simple in structure and low in cost, and is environmentally friendly and reliable. The device effectively realizes the sealing of the sealed container, ensures the smoothness of the discharge of the waste liquid, and can also accurately control the discharge volume, preventing the VOCs in the waste liquid from volatilizing into the atmosphere and causing harm to the environment and personal safety.

[0022] (4) During the liquid discharge process, both the first and second valves are opened, and the liquid is discharged through the second pipe structure, the pipe tee, and the discharge pipe; air enters the container through the air vent and the first pipe structure, forming a closed loop. When sealing is required, the first and second valves are closed, and the liquid is stored in the container, preventing harmful substances in the container from evaporating.

[0023] (5) During the liquid discharge process, both the first valve and the second valve are opened, and the liquid is discharged through the second pipe structure, the pipe tee, and the discharge pipe. During the liquid discharge process, the rotating blades are driven to rotate, and the rotating blades set at equal angles on the shaft sleeve intermittently move the lower lever between different rotating blades.

[0029] The following embodiments are further described in conjunction with the accompanying drawings and examples. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0030] according to Figures 1 to 4 As shown, the present invention is a waste liquid storage container supporting discharge pipe, which includes

[0031] A first pipe structure 1, one end of which is connected to the top of the container side wall;

The first pipeline structure 1 is provided with a vent 11, and the vent 11 is located on the side of the first valve 10 close to the pipeline tee 3.

[0034] In the above technical solution, during liquid discharge, both the first and second valves are opened, allowing the liquid to be discharged through the second pipe structure, the pipe tee, and the discharge pipe; air enters the container through the vent and the first pipe structure, forming a closed loop. When sealing is required, the first and second valves are closed, and the liquid is stored in the container, preventing harmful substances from evaporating. If the liquid in the container is highly volatile and ventilation is required to ensure stable internal pressure, the first valve on the first pipe structure can be opened.

[0035] As a preferred embodiment of the above technical solution, it also includes a regulating structure 5 and a switch structure 6, wherein the switch structure 6 is installed in the first pipeline structure 1 and is used to open or close the air vent 11; the regulating structure 5 is installed in the pipeline tee 3, and the top of the regulating structure 5 is in movable contact with the bottom of the switch structure 6; when the liquid passes through the pipeline tee 3, the liquid can open or close the air vent 11 through the regulating structure 5 and the switch structure 6.

[0036] As a preferred embodiment of the above technical solution, the switch structure 6 includes a piston assembly 61 and a drive assembly 62 . The piston assembly 61 is used to open or close the air vent 11 , and the drive assembly 62 is used to drive the piston assembly 61 to open or close the air vent 11 .

[0037] As a preferred embodiment of the above technical solution, the piston assembly 61 includes a piston 610, a connecting rod 611, a guide plate 612, a first connecting column 613, a second connecting column 614, a spring 615 and a guide rod 616. The guide rod 616 is installed in the first pipe structure 1. A guide hole is opened on the guide plate 612. The guide plate 612 is sleeved on the guide rod 616 through the guide hole and can move freely along the guide rod 616. One end of the guide plate 612 is connected to the piston 610 through the connecting rod 611, and the other end of the guide plate 612 is connected to the first connecting column 613. The second connecting column 614 is installed on the inner wall of the first pipe structure 1. The two ends of the spring 615 are respectively connected to the first connecting column 613 and the second connecting column 614. The driving assembly 62 is used to drive the guide plate 612 to move along the guide rod 616, and drive the piston 610 to move to or away from the air vent 11 through the connecting rod 611 to open or close the air vent 11.

[0038] As a preferred embodiment of the above technical solution, the driving assembly 62 includes an upper shift rod 620, a lower shift rod 621, a connecting sleeve 622, and an upper fixed column 623. The upper fixed column 623 is installed in the pipe tee 3 and is located directly below the first pipe structure 1. The connecting sleeve 622 can be rotatably sleeved and installed on the upper fixed column 623.

The upper shift rod 620 pushes the guide plate 612 to move toward or away from the air vent 11.

[0039] In the above technical solution, a stopper is provided on the side of the upper lever facing away from the guide plate. This stopper effectively prevents the upper lever from significantly deviating from the guide plate.

A plurality of rotating blades 52 are installed on the sleeve 51. The lower end of the lower lever 621 is located between the rotating blades 52. When the rotating blades 52 rotate, they can contact the lower end of the lower lever 621. As the rotating blades 52 rotate, the lower end of the lower lever 621 leaves one group of rotating blades 52 and enters the next group of rotating blades 52.

The lower lever drives the upper lever to move back and forth through the connecting shaft sleeve, driving the guide plate to move back and forth along the guide rod. The guide plate drives the connecting rod and piston connected to it to move back and forth along the direction of the air vent, thereby realizing the opening and closing of the air vent. By setting a control structure and a switch structure, the air vent can be opened during the liquid outflow process, and the air vent can be kept in a closed state when the liquid is not outflowing, thereby preventing toxic gases from volatilizing when the first valve is opened.
