Description

A new liquid discharge structure of a cylindrical vertical container with a flat bottom structure

technical field

The invention relates to the technical field of vertical industrial storage containers, in particular to a novel liquid discharge structure of a cylindrical vertical container with a bottom flat cover structure.

Background technique

The cylindrical vertical container with flat bottom structure is a storage device widely used in industrial production for storing various solid materials, gases and liquids. The storage tank is composed of three parts: a flat bottom, a cylindrical tank wall and a tank top. Because the bottom adopts a flat cover structure, which saves the processing cost of the head and is easy to manufacture, this structure has been widely used. One type of cylindrical vertical container with a bottom flat cover structure (as shown in Figure 1) is composed of a bottom flat cover, a cylindrical body and an oval head at the top. The drain port in Figure 1 is connected by a flange, so the drain port needs to be a certain distance higher than the bottom plate. The traditional drain pipe structure is shown in Figure 2. The advantage of this structure is that the structure is simple, and the disadvantage is that the bottom of the storage tank There is too much liquid remaining and it cannot be discharged. In view of the disadvantages of this structure, a new type of liquid discharge structure suitable for cylindrical vertical containers with a flat bottom structure is specially designed.

Preferably, the end of the elbow is provided with a self-adjusting floating device, and the self-adjusting floating device includes a hollow annular shell, a connecting plate and a sliding sleeve, and the bottom end of the sliding sleeve is provided with a slot, The sliding sleeve is slidingly sleeved on the tail of the elbow, and the upper part of the sliding sleeve is fixedly connected with a connecting plate, and the connecting plate is fixedly provided with an annular shell.

Preferably, a limit stop ring is fixedly arranged on the outer wall of the elbow, and the limit stop ring is located above the sliding sleeve.

Preferably, the flange, the elbow, and the outer wall of the elbow and the wall of the vertical container are fixedly connected by welding.

Beneficial effect: Compared with the prior art, the beneficial effect of the present invention is: under the requirement of medium corrosion allowance, the structure has certain applicability to both normal pressure storage tank and pressurized storage tank, and can Drain the liquid in the storage tank as much as possible to meet the customer's requirements.

Implementation

In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, in the case of no conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

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 than described here. Therefore, the present invention is not limited to the specific embodiments disclosed below. limit.

Example

Please refer to the accompanying drawings of the description. In the embodiment of the present invention, a new type of liquid discharge structure for a cylindrical vertical container with a bottom flat cover structure includes a flange 1 and an elbow 2, and the flange 1 is fixedly connected to the elbow. The outlet of the pipe 2, the end of the elbow 2 extends into the interior of the container and is close to the bottom plate of the container, and the end of the elbow 2 is uniformly opened with a number of slots 3 . The distance between the end of the elbow 2 and the bottom plate is relatively short, so that the liquid medium in the storage tank can be drained as much as possible. In order to reduce the liquid resistance, some slots 3 are opened at the end of the elbow 2, and large particles of impurities can be filtered to prevent them from randomly The liquid medium is discharged from the storage tank. Its advantage is that the structure is simple and economical, and its disadvantage is that even if there is a lot of liquid in the storage tank, the liquid discharge resistance is relatively large.

Example

A new type of liquid discharge structure for a cylindrical vertical container with a flat bottom structure, including a flange 1 and an elbow 2, the flange 1 is fixedly connected to the outlet of the elbow 2, and the end of the elbow 2 A self-adjusting floating device 4 is provided. The self-adjusting floating device 4 includes a hollow annular shell 6, a connecting plate 7 and a sliding sleeve 8. The bottom end of the sliding sleeve 8 is provided with a slot 3. The The sliding sleeve 8 is slidingly sleeved on the tail of the elbow 2, and the upper part of the sliding sleeve 8 is fixedly connected with a connecting plate 7, and the connecting plate 7 is fixedly provided with an annular shell 6; A limit stop ring 5 is fixedly arranged on the outer wall of 2, and the limit stop ring 5 is located above the sliding sleeve 8. Compared with Embodiment 1, this structure can ensure that there is a certain distance between the end of the elbow and the bottom plate, which can ensure that the resistance of liquid discharge can be reduced when there is a lot of liquid in the storage tank. The function of the slot is that when the sliding sleeve touches the bottom plate, one is to filter the liquid medium and the other is to allow the liquid medium to be sucked out by the pump through the slot. The sliding sleeve and the straight edge of the elbow adopt a clearance fit. In this way, when the liquid in the storage tank is at a high liquid level, the self-adjusting floating device floats upwards under the action of liquid buoyancy until it reaches the position of the positioning retaining ring and stops rising under the blocking of the positioning retaining ring. 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 decline of the hollow annular shell until the bottom of the sliding sleeve descends to the lower edge of the straight section of the elbow, after which the self-adjusting The floating device comes into play, and the sliding sleeve also descends as the liquid level descends, so that the liquid in the lower part of the straight section of the elbow can also be sucked out under the action of the pump.

In particular, the flange 1, the elbow 2, and the outer wall of the elbow 2 and the wall of the vertical container are fixedly connected by welding.

The above are only preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, some modifications and improvements can be made without departing from the concept of the present invention, and these should also be regarded as protection of the present invention. None of these will affect the effect of implementing the present invention and the practicability of the patent.
