Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of inlet connectors for storage tanks, and more specifically, to an inlet connector for storage tanks. Background Technology

[0002] In numerous industries such as chemical production and oil refining, storage tanks serve as crucial equipment for storing various liquid raw materials, and their safety and service life directly impact the continuity and stability of production. The inlet connector, as a vital component connecting the storage tank to external feed pipelines, is of paramount importance in its design.

[0003] Taking the new acid tank in an acid regeneration unit as an example, the traditional inlet joint design has many drawbacks. For instance, the existing new acid tank in an acid regeneration unit has a volume of 120m³, a diameter of 4500mm, and a height of 8000mm. The new acid unloading pipe is DN65 and located at the top of the tank, connected by a flange fixed to the top. During unloading, due to the tank's height, columnar new acid directly impacts the bottom of the tank from the top pipe. Although a 30-50mm layer of fine sand is laid at the bottom to reduce wear, long-term impact causes the sand to accumulate around the tank, creating voids at the bottom. If columnar new acid impacts the bottom again, it can easily cause cracks, leading to hydrochloric acid leakage. This not only wastes raw materials but also severely pollutes the environment, posing a significant threat to personnel safety and the normal operation of the equipment.

[0004] Besides acid tanks, other types of storage tanks also face similar problems during the feeding process. For example, in some tanks storing corrosive liquids, the impact force of the liquid during feeding can cause corrosion and damage to the tank bottom and the area around the inlet, reducing the service life of the tank. Furthermore, for tanks storing flammable and explosive liquids, an improperly designed inlet can lead to safety accidents.

[0005] With the continuous expansion of industrial production scale and the increasing demands for safe production, the shortcomings of traditional tank inlet connectors in terms of impact resistance and leakage prevention have become increasingly apparent. Developing a tank inlet connector that can effectively disperse the impact force of feed, prevent liquid leakage, and extend the service life of the tank is urgently needed. This is of great practical significance for ensuring production safety, reducing production costs, and minimizing environmental pollution. Utility Model Content

[0006] To overcome the above-mentioned defects, the embodiments of this disclosure provide a feed inlet connector for a storage tank, which solves the technical problem in the prior art where long-term impact causes the fine sand spread on the bottom of the tank to accumulate in all directions, resulting in a hollowed-out bottom. Once the columnar new acid impacts the bottom of the tank again, it is very easy to cause the bottom of the tank to crack and cause hydrochloric acid leakage.

[0007] According to one aspect, at least one embodiment of this disclosure provides a feed inlet connector for a storage tank, comprising:

[0008] A flange and a lower pipe, wherein the lower pipe is disposed at the bottom of the flange;

[0009] A connecting and dispersing assembly is disposed between the flange and the lower pipe;

[0010] A docking assembly, wherein the docking assembly is disposed at the upper end of the flange;

[0011] The connecting and dispersing assembly includes a boss, which is disposed at the bottom of the flange. A mating groove is formed between the boss and the lower end of the flange. An annular groove is formed around the inner surface of the mating groove, and the lower pipe is inserted into the mating groove.

[0012] As a further technical solution, a rotating platform is provided around the lower pipe side surface, and the rotating platform slides and fits in the annular groove. Sliding grooves are provided around the inner surface of the annular groove and around the side surface of the rotating platform.

[0013] As a further technical solution, the sliding grooves are filled with a number of balls, a sealing ring is provided around the side surface of the rotary table, a number of feed holes are opened on the surface of the lower tube, and a number of buffer plates are provided on the side surface of the lower tube.

[0014] As a further technical solution, the docking assembly includes a connecting pipe, which is disposed on the top of the flange, and a pair of gaskets are fitted around the side surface of the connecting pipe.

[0015] As a further technical solution, each group of adjacent feed holes is staggered vertically.

[0016] As a further technical solution, the buffer plates are all arc-shaped transition structures, and the positions of the buffer plates and the feed holes correspond to each other.

[0017] As a further technical solution, the flange has a double-layer structure.

[0018] As a further technical solution, the lower end of the lower tube has a circular structure, and the feed hole at the lowest end is spaced apart from the bottom of the lower tube.

[0019] The beneficial effects of the embodiments disclosed herein are as follows:

[0020] 1. The beneficial effect of the connecting dispersion component in this disclosure is that it effectively solves the problem of material impacting the tank bottom during tank feeding. By setting the feed hole, the material no longer impacts the tank bottom in a concentrated manner, but instead disperses into the tank, fundamentally reducing the degree of impact on the tank bottom. The design of the buffer plate is crucial. When the material impacts the buffer plate, its arc-shaped structure disperses the impact force, reducing the direct force on the tank bottom and preventing the tank bottom from cracking due to long-term impact. Moreover, the impact of the buffer plate causes the lower pipe to rotate, changing the angle at which the material enters the tank, further dispersing the material. In addition, the ball bearings reduce the friction between the lower pipe and the docking groove, making the lower pipe rotate more flexibly, which is more conducive to material dispersion. The sealing ring ensures the sealing of the connection, preventing material leakage and avoiding material loss and environmental pollution.

[0021] 2. The beneficial effect of the docking assembly in this disclosure is that the connecting pipe, as a component connecting with an external pipeline, provides a channel for material feeding. A pair of gaskets on the side surface of the connecting pipe enhances the sealing at the connection with the external pipeline, effectively preventing material leakage. During installation, its design facilitates connection with external pipelines of different specifications; simply align the external pipeline with the connecting pipe and tighten with bolts, improving the versatility and adaptability of the joint. This allows the feed port connector to be widely used in various storage tank feeding scenarios, whether it be corrosive liquid storage tanks in the chemical industry or raw material storage tanks in oil refining, ensuring a stable and safe connection to external feed pipelines and guaranteeing the smooth progress of the feeding process.

[0033] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0034] like Figures 1-4 As shown, it illustrates an inlet connector for a storage tank according to an embodiment of the present disclosure, comprising:

[0035] Flange 1 and lower pipe 2, wherein the lower pipe 2 is disposed at the bottom of flange 1;

[0036] A connecting dispersion component 3 is disposed between the flange 1 and the lower pipe 2;

[0037] The docking assembly 4 is disposed on the upper end of the flange 1;

[0038] The connecting and dispersing component 3 includes a boss 3-1, which is located at the bottom of the flange 1. A mating groove 3-2 is formed between the boss 3-1 and the lower end of the flange 1. An annular groove 3-3 is formed around the inner surface of the mating groove 3-2. The lower pipe 2 is inserted into the mating groove 3-2. A rotating platform 3-4 is formed around the side surface of the lower pipe 2. The rotating platform 3-4 slides against the annular groove 3-3. Sliding grooves 3-5 are formed around the inner surface of the annular groove 3-3 and around the side surface of the rotating platform 3-4. Several ball bearings 3-6 are filled between the sliding grooves 3-5. A sealing ring 3-7 is formed around the side surface of the rotating platform 3-4. Several sets of feed holes 3-8 are formed on the surface of the lower pipe 2. Several buffer plates 3-9 are formed on the side surface of the lower pipe 2.

[0039] In some examples, excessive feed pressure during tank feeding operations can cause significant damage to the tank. Therefore, a connecting and dispersing assembly 3 was designed. This assembly is based on a boss 3-1 located at the bottom of flange 1. The boss 3-1 and the mating groove 3-2 at the lower end of flange 1 provide a precise and stable installation space for the lower pipe 2. The lower pipe 2 is tightly inserted into the mating groove 3-2, and its side surface rotating platform 3-4 slides against the annular groove 3-3 on the inner surface of the mating groove 3-2. This design not only forms a stable connection structure but also allows for the rotation of the lower pipe 2. Several ball bearings 3-6 filled in the sliding groove 3-5 on the inner surface of the annular groove 3-3 and the side surface of the rotating platform 3-4 of the lower pipe 2 greatly reduce the friction between the lower pipe 2 and the mating groove 3-2, allowing the lower pipe 2 to rotate relatively flexibly. The sealing rings 3-7 set around the circumference of the rotating table 3-4 act as a sturdy barrier, ensuring the sealing of the connection and effectively preventing material leakage, thus avoiding material loss and environmental pollution caused by leakage.

[0040] Several sets of feed holes 3-8 are formed on the surface of the lower pipe 2. These feed holes 3-8 allow the injected hydrochloric acid and other materials to disperse into the storage tank, avoiding concentrated impact on the tank bottom and reducing the risk of damage to the tank bottom from the source. Several buffer plates 3-9 are set on the side surface of the lower pipe 2, which play a buffering role during material injection. When the material impacts the buffer plates 3-9, the buffer plates 3-9 disperse the impact force of the material, reducing the direct force on the bottom of the storage tank, thereby effectively preventing the bottom of the tank from cracking due to excessive impact. Moreover, when the impact of the material is withstood, the impact buffer plates 3-9 can also drive the lower pipe 2 to rotate, so that the angle of the material entering the storage tank is constantly changed, further dispersing the hydrochloric acid and ensuring the safety and stability of the storage tank in all aspects.

[0041] Through the coordinated operation of components such as boss 3-1, docking groove 3-2, annular groove 3-3, ball bearing 3-6, sealing ring 3-7, feed hole 3-8, and buffer plate 3-9, the connecting dispersion assembly 3 realizes the function of dispersing and injecting hydrochloric acid and buffering impact to protect the bottom of the storage tank.

[0042] like Figures 1-4 As shown in the figure, the docking assembly 4 in this embodiment includes a connecting pipe 4-1, which is disposed on the top of the flange 1, and a pair of gaskets 4-2 are fitted around the side surface of the connecting pipe 4-1.

[0043] In some examples, during the installation of the tank inlet connector, a docking assembly 4 is designed to connect with external pipelines. This assembly includes a connecting pipe 4-1 positioned on top of the flange 1, serving as a key component for docking with the external pipeline. A pair of gaskets 4-2, fitted around the side surface of the connecting pipe 4-1, enhance the sealing and stability of the connection between the connecting pipe 4-1 and the external pipeline. During installation, the external pipeline is aligned with the connecting pipe 4-1, and the two are secured using bolts or other fasteners. The gaskets 4-2 fill the connection gaps, preventing material leakage and ensuring the safety and reliability of the feeding process. Simultaneously, this structural design facilitates the connection and installation of the docking assembly 4 with external pipelines of different specifications, improving the versatility and adaptability of the connector. Through the collaborative work of components such as the connecting pipe 4-1 and the gaskets 4-2, the docking assembly 4 achieves the function of connecting and installing with external pipelines.

[0044] For example, such as Figure 3 As shown, each group of adjacent feed holes 3-8 is staggered vertically.

[0045] In some examples, by staggering the upper and lower parts, the range of feed holes 3-8 can be further distributed, which can make the hydrochloric acid more dispersed and less likely to interfere with each other.

[0046] For example, such as Figure 2As shown, the buffer plates 3-9 are all arc-shaped transition structures, and the positions of the buffer plates 3-9 and the feed holes 3-8 are corresponding.

[0047] In some examples, the arc-shaped transition structure allows the lower tube 2 to rotate stably after being impacted by hydrochloric acid.

[0048] For example, such as Figure 4 As shown, the flange 1 has a double-layer structure.

[0049] In some examples, the double-layer structure can increase the connection strength of flange 1 and provide stronger pressure resistance.

[0050] For example, such as Figure 3 As shown, the lower end of the lower tube 2 has a circular structure, and the feed hole 3-8 at the lowest end is spaced apart from the bottom of the lower tube 2.

[0051] In some examples, the presence of gaps allows for the formation of internal buffer chambers, which can mitigate the impact of hydrochloric acid entering the system.

[0052] In practical use: First, take advantage of the double-layer structure of flange 1 and use bolts or other fasteners to securely install it on top of the storage tank, ensuring a firm installation and good seal. Next, align the connecting pipe 4-1 of the docking assembly 4 with the external feed pipe, ensuring that the pair of gaskets 4-2 on the side surface of the connecting pipe 4-1 are tightly fitted to the external pipe. Then, use bolts or other fastening devices to fix the two together, ensuring the sealing and stability of the connection. Regarding the connecting and dispersing assembly 3, insert the lower pipe 2 into the space formed by the bottom boss 3-1 and the docking groove 3-2 of flange 1, allowing the rotating platform 3-4 on the side surface of the lower pipe 2 to slide against the annular groove 3-3 in the docking groove 3-2. During dynamic fitting, the ball bearings 3-6 in the annular groove 3-3 and the sliding groove 3-5 on the side surface of the rotating table 3-4 play their role, reducing friction and allowing the lower tube 2 to rotate flexibly. The sealing ring 3-7 on the side surface of the rotating table 3-4 ensures that there is no leakage at the connection. After everything is installed, the feed pipe is opened, and the material is dispersed into the storage tank through the feed hole 3-8 on the surface of the lower tube 2. The buffer plate 3-9 buffers the impact force of the material and drives the lower tube 2 to rotate, further dispersing the material. Since the adjacent feed holes 3-8 are staggered vertically, the material can be more evenly dispersed. The gap between the bottom feed hole 3-8 and the bottom of the lower tube 2 forms a buffer cavity, which also helps to alleviate the impact force of the material.
