[0016] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0017] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification. Embodiment

[0018] Referring to the accompanying drawings of the specification, in an embodiment of the present invention, a novel liquid discharging structure for a cylindrical vertical container with a flat bottom cover structure includes a flange 1 and a bent pipe 2. The flange 1 is fixedly connected to the outlet of the bent pipe 2. The end of the bent pipe 2 extends into the interior of the container and is close to the bottom plate of the container. A plurality of slot holes 3 are evenly formed at the end of the bent pipe 2. The end of the bent pipe 2 is relatively short from the bottom plate, which can drain the liquid medium in the storage tank as much as possible. In order to reduce the liquid discharging resistance, some slot holes 3 are formed at the end of the bent pipe 2, and large particle impurities can be filtered to prevent them from being discharged from the storage tank along with the liquid medium. Its advantages are simple structure and economy, and its disadvantage is that the liquid discharging resistance is relatively large even when there is a relatively large amount of liquid in the storage tank. Embodiment

[0019] A novel liquid discharging structure for a cylindrical vertical container with a flat bottom cover structure includes a flange 1 and a bent pipe 2. The flange 1 is fixedly connected to the outlet of the bent pipe 2. A self-adjusting floating device 4 is arranged at the end of the bent pipe 2. The self-adjusting floating device 4 includes a hollow annular pipe shell 6, a connecting plate 7 and a sliding sleeve 8. Slot holes 3 are formed at the bottom end of the sliding sleeve 8. The sliding sleeve 8 is slidably sleeved on the tail of the bent pipe 2. A connecting plate 7 is fixedly connected to the upper part of the sliding sleeve 8, and an annular pipe shell 6 is fixedly arranged on the connecting plate 7. A limiting retaining ring 5 is fixedly arranged on the outer wall of the bent pipe 2, and the limiting retaining ring 5 is located above the sliding sleeve 8. This structure can ensure a certain distance between the end of the bent pipe and the bottom plate compared with Embodiment 1, so that the liquid discharging resistance can be reduced when there is a relatively large amount of liquid in the storage tank. The function of the slot holes is that when the sliding sleeve contacts the bottom plate, on the one hand, it plays a filtering role for the liquid medium, and on the other hand, the liquid medium can be sucked out by the pump through the slot holes. A clearance fit is adopted between the sliding sleeve and the straight section of the bent pipe. In this way, when the liquid in the storage tank is at a high liquid level, under the action of the buoyancy of the liquid, the self-adjusting floating device floats upward until it rises to the position of the positioning retaining ring and is blocked by the positioning retaining ring and no longer rises. When the liquid in the storage tank is reduced to a certain extent, the sliding sleeve of the self-adjusting floating device descends with the descent of the hollow annular pipe shell until the bottom of the sliding sleeve descends to the lower edge of the straight section of the bent pipe. After that, the self-adjusting floating device starts to work. As the liquid level descends, the sliding sleeve also descends, so that the liquid at the lower part of the straight section of the bent pipe can also be sucked out under the action of the pump.

[0020] Particularly, the flange 1 and the bent pipe 2, as well as the outer wall of the bent pipe 2 and the wall of the vertical container, are fixedly connected by welding.

[0021] The above are only the preferred embodiments of the present invention. It should be noted that for those skilled in the art, without departing from the concept of the present invention, several deformations and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicability of the patent.
