Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0036] This embodiment provides a vacuum liquid storage tank. By providing a movable damping plate and a fixed damping plate, it can effectively suppress the oscillation and fluctuation of the liquid in the tank, reduce the noise during transportation, and improve the transportation safety.
[0037] Specifically, as Figures 1 - 3 shown, the vacuum liquid storage tank includes a tank body 100, a movable damping plate 200, a damper 300, and a fixed damping plate 400. Among them, the tank body 100 is filled with liquid. The movable damping plate 200 is arranged in the tank body 100 and is located above the liquid. The outer peripheral wall of the movable damping plate 200 is slidably connected to the inner peripheral wall of the tank body 100. One end of the damper 300 is hinged to the top of the tank body 100, and the other end is hinged to the movable damping plate 200. The fixed damping plate 400 is arranged in the tank body 100 and is located between the movable damping plate 200 and the bottom of the tank body 100. A plurality of through holes 410 for liquid to flow through are provided on the fixed damping plate 400.
[0038] When the vacuum liquid storage tank is working, generally, the liquid level in the tank body 100 is higher than the fixed anti-slosh plate 400 adjacent to the movable anti-slosh plate 200. Under the action of the damper 300, the movable anti-slosh plate 200 will float on the liquid at this time and can apply a certain degree of pressure to the liquid. When the vacuum liquid storage tank is in transportation and the liquid in the tank body 100 surges to one side of the tank due to vehicle bumps or sudden braking, etc., resulting in an instantaneous fluctuation, the liquid will impact the movable anti-slosh plate 200. At this time, the damper 300 will damp the movement of the movable anti-slosh plate 200, reduce the movement speed of the movable anti-slosh plate 200, so that the moving distance of the movable anti-slosh plate 200 within a short time is small, thereby hindering the instantaneous fluctuation of the liquid in the tank body 100. That is, through the cooperation of the damper 300 and the movable anti-slosh plate 200, the oscillation effect of the liquid in the vacuum liquid storage tank during transportation is effectively suppressed, which not only reduces the transportation noise caused by liquid oscillation, but also reduces the off-load risk caused by excessive liquid oscillation in the tank body 100, improves the vehicle-mounted environment, and enhances the safety of transporting the vacuum liquid storage tank.
[0039] Moreover, by providing a plurality of through holes 410 on the fixed anti-slosh plate 400, the liquid needs to pass through the through holes 410 to flow from one side of the fixed anti-slosh plate 400 to the other side, increasing the difficulty of liquid flow, and thus can suppress the oscillation of the liquid in the tank body 100 to a certain extent. The fixed anti-slosh plate 400 cooperates with the movable anti-slosh plate 200 to further suppress the oscillation of the liquid in the tank body 100.
[0040] It should be noted that the movement distance of the movable anti-slosh plate 200 is limited, and the movement distance of the movable anti-slosh plate 200 is related to the maximum elongation length of the damper 300. When the liquid level in the vacuum liquid storage tank is lower than the liquid level of the fixed anti-slosh plate 400, the oscillation of the liquid in the vacuum liquid storage tank is mainly suppressed by the fixed anti-slosh plate 400, and at this time, the anti-slosh effect of the movable anti-slosh plate 200 is small.
[0041] It should be noted that there is a vacuum between the top of the tank body 100 and the movable anti-slosh plate 200.
[0042] Optionally, in this embodiment, the vacuum liquid storage tank is a vertical liquid storage tank, the damper 300 extends along the axial direction (vertical direction) of the tank body 100, and the movable anti-slosh plate 200 and the fixed anti-slosh plate 400 are arranged in parallel at intervals along the axial direction of the tank body 100.
[0043] Further, continue to refer to Figure 1, a seal 500 is provided on the outer peripheral wall of the movable baffle 200, and the seal 500 is slidably attached to the inner peripheral wall of the tank body 100. By providing the seal 500, on the one hand, it can seal the gap between the movable baffle 200 and the tank body 100 to prevent the liquid in the tank body 100 from passing over the movable baffle 200 during the oscillation process; on the other hand, it can increase the friction between the movable baffle 200 and the inner wall of the tank body 100, and this friction can hinder the movement of the movable baffle 200 to a certain extent. The seal 500 cooperates with the damper 300 to further improve the ability of the movable baffle 200 to suppress liquid oscillation.
[0044] Optionally, continue to refer to Figure 3 , in this embodiment, the seal 500 is an O-ring 510, and an annular groove 511 is provided on the inner peripheral wall of the O-ring 510. The O-ring 510 is sleeved on the movable baffle 200 through the annular groove 511. The connection between the O-ring 510 and the movable baffle 200 is realized through the annular groove 511, and the structure is simple, which is convenient for the installation and disassembly of the O-ring 510.
[0045] Furthermore, continue to refer to Figure 1 , between the movable baffle 200 and the fixed baffle 400 adjacent to the movable baffle 200, a limiting flange 110 is provided on the inner peripheral wall of the tank body 100. The limiting flange 110 can abut against the movable baffle 200 to limit the movement of the movable baffle 200. By providing the limiting flange 110, it can prevent the movable baffle 200 from contacting the fixed baffle 400 and causing poor connection between the fixed baffle 400 and the tank body 100, effectively protecting the fixed baffle 400.
[0046] Optionally, the limiting flange 110 can be annular. With this setting, the limiting effect on the movable baffle 200 is better, and the force on the movable baffle 200 is more uniform.
[0047] Furthermore, in this embodiment, the side of the limiting flange 110 facing away from the movable baffle 200 abuts against the fixed baffle 400. By arranging the limiting flange 110 closely against the fixed baffle 400, while ensuring the limiting effect, it can make the movement distance of the movable baffle 200 longer, improving the oscillation suppression performance of the vacuum liquid storage tank.
[0048] Optionally, continue to refer to Figure 1 , multiple dampers 300 can be provided, and the multiple dampers 300 are arranged at equal intervals along the circumferential direction of the movable baffle 200. With such an arrangement, it can improve the force uniformity of the movable baffle 200, reduce the risk of deformation of the movable baffle 200, and thus is beneficial to extending the service life of the movable baffle 200.
[0049] In this embodiment, three dampers 300 are provided, and the three dampers 300 are arranged at intervals of 120° along the circumferential direction of the moving anti-sway plate 200. Of course, in other embodiments, the number of dampers 300 can also be other, which can be set according to actual needs, and the present application does not make specific limitations.
[0050] Further, referring to Figure 1 again, multiple fixed anti-sway plates 400 can also be provided, and the multiple fixed anti-sway plates 400 are arranged at intervals along the axial direction of the tank body 100. By providing multiple fixed anti-sway plates 400, the anti-sway effect can be further improved.
[0051] It can be understood that the number of fixed anti-sway plates 400 can be set according to the height of the tank body 100.
[0052] In this embodiment, three fixed anti-sway plates 400 are provided. In other embodiments, the number of fixed anti-sway plates 400 can also be other, such as one, two, four, etc., which can be set according to actual needs, and the present application does not make specific limitations.
[0053] Optionally, in this embodiment, the fixed anti-sway plate 400 is connected to the inner peripheral wall of the tank body 100 by welding. In other embodiments, the fixed anti-sway plate 400 can also be fixed to the tank body 100 by other means, which can be set according to actual needs, and the present application does not make specific limitations.
[0054] Optionally, in this embodiment, the damper 300 is a friction damper.
[0055] Further, as Figure 4 shown, a vacuum gauge flange interface 120 is further provided on the tank body 100. The vacuum gauge flange interface 120 is located between the moving anti-sway plate 200 and the top of the tank body 100. The vacuum gauge is installed on the tank body 100 through the vacuum gauge flange interface 120, and the vacuum gauge is used to measure the vacuum degree of the space between the moving anti-sway plate 200 and the top of the tank body 100.
[0056] Optionally, referring to Figure 4 again, a liquid level display flange interface 130 can also be provided on the tank body 100. The display module of the liquid level gauge is installed at the liquid level display flange interface 130, and the measuring module of the liquid level gauge is arranged inside the tank body 100 and is used to measure the liquid level inside the tank body 100. That is, the liquid level inside the tank body 100 can be understood in real time through the liquid level display flange interface 130, which is convenient for timely understanding of the liquid level information.
[0057] Optionally, referring to Figure 4 again, a vacuum pump flange interface 140 for connecting to a vacuum pump is provided on the tank body 100, and the vacuum pump is used to evacuate the tank body 100.
